Description

CROSS REFERENCE TO RELATED APPLICATION

This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2005-045268, filed on Feb. 22, 2005.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a gaming machine having a speaker and, more particularly, to a speaker enclosing structure.
2. Description of Related Art
Hitherto, a gaming machine having a speaker on a front door is known as described in Japanese Patent Application Laid-Open No. 2003-180959.
The gaming machine described in Japanese Patent Application Laid-Open No. 2003-180959 includes a built-in speaker having a sound emitting part in which a speaker grille formation part is formed in a front portion. The built-in speaker is attached to an upper part of a front door from the rear side so that the sound emitting part faces forward. Moreover, to improve the sound quality, an enclosure covers the rear of the sound emitting part of the built-in speaker, thereby forming a single closed space in cooperation with the speaker grille formation part. That is, the rear of the sound emitting part of the built-in speaker is sealed by the enclosure.
As described above, in the conventional gaming machine, a sound emitting face of the built-in speaker, that is, the rear face of the speaker grille formation part of the sound emitting part has to be covered with a speaker box (enclosure).
According to the size of the speaker box, the characteristics of sound also change. To be specific, the larger the speaker box is, that is, the larger the capacity of the speaker box is, the more the characteristics of sound improve.
Consequently, a gaming machine having a speaker box of capacity which is as large as possible to improve the characteristics of sound (sound quality) is conventionally desired.
However, the body of the conventional gaming machine is provided with boards such as a display control board for controlling display of an effect image and gaming parts such as a ball path. In relation with the limit of the arcade facility, and the like, the size of the gaming machine is regulated. In a gaming machine of a limited size, a speaker box has to be formed.
A gaming machine provided with a speaker box having capacity as large as possible for improvement of the characteristics of sound (sound quality) is not realized or proposed at present.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a gaming machine in which a speaker enclosing box having a large capacity can be formed under limit of the size of the gaming machine itself.
A gaming machine of the present invention includes: a body supported by an outer frame to be attached to a game machine island in a game arcade, provided with a predetermined mechanism necessary to execute a game, and formed integrally with a speaker enclosure having an opening and enclosing a speaker; and a lid covering the opening, and the lid is fit to the speaker enclosure, thereby forming a speaker enclosing box.
Since the body and the speaker enclosure are integrally formed, the space of the amount of the speaker enclosure (the space of the amount of the thickness of the speaker enclosure) in the case of forming the speaker enclosure separately from the body can be assured, and the speaker enclosing box (speaker box) can be increased according to the assured increase amount. Thus, the speaker enclosing box having large capacity can be formed under limit of the size of the gaming machine itself. Since the capacity of the speaker enclosing box can be increased, the sound quality can be improved. Since the body and the speaker enclosure are integrally formed as described above, it is not necessary to separately form the speaker enclosure. Consequently, the number of parts can be suppressed, efficiency of the assembling work of the gaming machine can be improved, and the cost can be reduced. Further, since the speaker enclosure is formed integrally with the body, the rigidity of the body can be increased by the speaker enclosure.
According to the present invention, the gaming machine may further include a storing tank in which gaming balls are stored. In the speaker enclosure, a box for enclosing the speaker is formed by a bottom portion, a top portion, side portions, and a rear portion, and the opening is formed so that the speaker is enclosed into the box from the surface side of the body. The storing tank is provided on the back side of a portion existing in the rear portion.
Since the storing tank is provided on the back side of a portion existing in the rear portion, the storing tank is supported by the side and bottom portions of the box of the speaker enclosure. Thus, the rigidity of the body even provided with the storing tank can be improved.

The gaming machine according to the present invention realizes improvement in the sound quality at the time of producing an effect related with sound (sound effect).
A speaker enclosure constructing a speaker enclosing box (speaker box) will now be described with reference to FIGS. 7 to 10.
FIG. 7 is a perspective view showing the front of the body (in the state where the attached parts are detached) according to the embodiment, and FIG. 8 is a perspective view showing the back (the rear) of the body illustrated in FIG. 7.
In the body 10, as shown in FIGS. 7 and 8, each of a speaker enclosure 310 having an opening 210 and enclosing the speaker 110, and a speaker enclosure 320 having an opening 220 and enclosing the speaker 120 is integrally formed.
In the speaker enclosure 310, bosses (attaching parts) 201 a, 201 b, 201 c, and 201 d for fixing the lid 410 which will be described later after the lid 410 is fit in the speaker enclosure 310 are formed around the opening 210.
Similarly, also in the speaker enclosure 320, bosses (attaching parts) 202 a, 202 b, 202 c, and 202 d for fixing the lid 420 which will be described later after the lid 420 is fit in the speaker enclosure 320 are formed around the opening 220.
As shown in FIG. 8, bosses (attaching parts) 203 a and 203 b for fixing one side in the longitudinal direction of the storing tank 130 are formed in the portion facing the opening 210 in the speaker enclosure 310, that is, on the back side of the body 10.
Similarly, bosses (attaching parts) 203 c and 203 d for fixing the other side in the longitudinal direction of the storing tank 130 are formed in a side portion in the position facing the opening 220 in the speaker enclosure 320, that is, on the back side.
Next, paying attention to the speaker enclosure 310 in the body 10, the speaker enclosure and the speaker enclosing box will be described.
In the speaker enclosure 310, as shown in FIG. 9, a box for enclosing the speaker 110 is formed by a bottom portion 311, a top portion 312, side portions 313 and 314, and a rear portion 315, and the opening 210 from which the speaker 110 is enclosed into the box from the surface side of the body 10 is formed. That is, the speaker enclosure 310 has a space (box) in which the speaker 110 is enclosed.
With the configuration of the body 10 in which the speaker enclosure having the space (box) is integrally formed, the following effects (1) to (3) can be expected.
(1) Since the body 10 and the speaker enclosure 310 are integrally formed, the space of the member of the speaker enclosure 310 (the space of the amount corresponding to the thickness of the member of the speaker enclosure) in the case of forming the speaker enclosure 310 separately from the body 10 can be assured. Consequently, the speaker enclosing box (speaker box) can be increased according to the assured increased space. Under limit of the size of the gaming machine, the speaker enclosing box having large capacity can be formed.
(2) In the body 10, the two speaker enclosures 310 and 320 each having a space (box) are integrally formed, so that the rigidity of the body 10 can be increased by the two speaker enclosures 310 and 320 each formed to have a space (box).
(3) Since the body 10 and the two speaker enclosures 310 and 320 are integrally formed, it is not necessary to separately form speaker enclosures. Consequently, the number of parts can be suppressed, efficiency of the assembling work of the pachinko gaming machine 1 can be improved, and the cost can be reduced.
In the speaker enclosure 310, as shown in FIG. 9, vibration regulating parts (ribs) 311 a, 312 a, 313 a, 314 a, and 315 a (in FIG. 9, the vibration regulating part 314 a is not shown) that regulate vibrations of the speaker enclosure 310 are formed on the inside of the bottom portion 311, top portion 312, side portions 313 and 314, and rear portion 315, respectively. Each of the vibration regulating parts 311 a, 312 a, 313 a, 314 a, and 315 a has a projection shape projected from the speaker enclosure 310.
In the embodiment, the vibration regulating parts (ribs) 311 a, 312 a, 313 a, 314 a, and 315 a are formed integrally with the speaker enclosure 310.
In other words, the vibration regulating parts, the speaker enclosure 310, and the body 10 are integrally formed.
FIG. 10 is a cross section showing a section of the speaker enclosure 310 seen from the direction A of FIG. 9. In FIG. 10, the portion indicated by the thick line corresponds to the speaker enclosure 310.
In the example shown in FIG. 10, the bottom portion 311, top portion 312, side portion 313, rear portion 315, and vibration regulating parts 311 a, 312 a, 313 a, and 315 a are illustrated as separate members. In the embodiment, as described above, the bottom portion 311, top portion 312, side portion 313 and rear portion 315, and vibration regulating parts 311 a, 312 a, 313 a, and 315 a are integrally formed.
Since the speaker enclosure 320 has a configuration similar to that of the speaker enclosure 310, description of the configuration of the speaker enclosure 320 will not be repeated.
As described above, by the configuration of the speaker enclosure in which the vibration regulating parts are integrally formed, the following effects (1) to (4) can be expected.
(1) For example, in the speaker enclosure 310, the vibration regulating parts 311 a, 312 a, 313 a, 314 a, and 315 a for regulating vibrations of the speaker enclosure 310 are formed. Consequently, unnecessary vibrations of the speaker enclosure 310 caused by sound vibrations (residual sound vibrations) of the speaker 110 are prevented, and the sound quality can be improved.
(2) For example, since the vibration regulating parts are formed on the inside of the speaker enclosure 310, the space in the speaker enclosure 310 is effectively used, unnecessary vibrations of the speaker enclosure 310 caused by the sound vibrations (residual sound vibrations) of the speaker 110 are prevented, and the sound quality can be improved.
(3) Since the projections are formed as the vibration regulating parts in, for example, the speaker enclosure 310, the rigidity of the speaker enclosure 310 can be increased by the projections.
(4) Since the vibration regulating parts and, for example, the speaker enclosure 310 are integrally formed, it is unnecessary to separately form the vibration regulating parts and the number of parts can be suppressed. Thus, efficiency of the assembling work of the gaming machine can be improved, and the cost can be reduced.
In the embodiment, as already described, the storing tank 130 is provided in each of portions existing in the positions facing the openings 210 and 220 in the boxes of the speaker enclosures 310 and 320, that is, the back side of the rear portion.
With respect to, for example, the speaker enclosure 310, the bosses 203 a and 203 b are formed in the back surface of the rear portion 315. Therefore, one side in the longitudinal direction of the storing tank 130 is fixed by attaching parts such as screws. In this case, the speaker enclosure 310 supports the storing tank 130 by the bottom portion 311 and the side portions 313 and 314.
With respect to the speaker enclosure 320 as well, in a manner similar to the case of the speaker enclosure 310, the bosses 203 c and 203 d are formed in the portions existing in the positions facing the opening 220, that is, in the rear portion. Therefore, the other side in the longitudinal direction of the storing tank 130 is fixed by attaching members such as screws. In this case, the speaker enclosure 320 supports the storing tank 130 by the bottom portion (which corresponds to the bottom portion 311) and the side portions (which correspond to the side portions 313 and 314).
As described above, the storing tank 130 is provided in the portion existing in the position facing the openings 210 and 220 in the box formed by the bottom portion, the top portion, the side portions, and the rear portion, that is, on the back side of the rear portion, so that the storing tank 130 is supported by the side portions and the bottom portion in the box of the speaker enclosure. Thus, the rigidity of the body 10 having the storing tank 130 can be improved.
The lid as a component of the speaker enclosure, that is, the lid which is fit in the above-described speaker enclosure will now be described with reference to FIGS. 11 to 15.
FIG. 11 is a perspective view showing the back of the lid 410, and FIG. 12 is a perspective view showing a state where the speaker 110 is mounted on the lid 410 illustrated in FIG. 11.
The lid 410 is formed by, as shown in FIG. 11, a bottom portion 411, a top portion 412, side portions 413 and 414, and a front portion 415. An opening (opening portion) is formed in a portion (rear portion) facing the front portion 415. Such a lid 410 covers the opening 210 in the speaker enclosure 310 so that the opening faces the speaker enclosure 310.
A sound emitting opening 416 for emitting sound generated by the speaker 110 is formed in the front portion 415 of the lid 410. The speaker 110 is attached to the sound emitting opening 416 in the lid 410.
Specifically, bosses 417 a, 417 b, 417 c, and 417 d for fixing the speaker 110 are formed in portions around the sound emitting opening 416 in correspondence with attachment holes 111 a, 111 b, 111 c, and 111 d, respectively, (the attachment hole 111 d is not shown in FIG. 12) of the speaker 110 shown in FIG. 12.
Ribs 418 a and 418 b are provided near the bosses 417 a and 417 d, respectively. In the case where the speaker 110 is placed in a predetermined position in the sound emitting opening 416 to fix the speaker 110 in the sound emitting opening 416, the movement of the speaker 110 is regulated by the ribs 418 a and 418 b, so that the four bosses 417 a to 417 d and the four attachment holes 111 a to 111 d of the speaker 110 match with each other. Consequently, the speaker 110 can be easily fixed to the sound emitting opening 416.
By screwing fittings such as screws to the four bosses 417 a to 417 d via the four attachment holes 111 a to 111 d of the speaker 110, the speaker 110 is fixed to the sound emitting opening 416 in the lid 410. FIG. 13 is a perspective view showing the front of the lid 410 to which the speaker 110 is fixed as described above.
In the embodiment, the position of disposing the sound emitting opening 416 can be changed (design can be changed) within the range that the speaker 110 in the front portion 415 can be attached. That is, the design can be changed so that the sound emitting opening 416, that is, the speaker 110 is disposed in a desired position in the front portion 415 in consideration of the bosses 417 a to 417 d and the ribs 418 a and 418 b.
In this case, even when the design of the position of disposing the sound emitting opening 416 is changed, no influence is exerted on, for example, the speaker enclosure 310 in which the speaker 110 is housed and the cover 6 covering the lids 410 and 420. Consequently, the designer can concentrate on a design change of the sound emitting opening 416, that is, only the lid.
Since, for example, the speaker 110 is attached to the sound emitting opening 416 in the lid 410 as described above, without changing the design of the speaker enclosure 310, the design of the position of disposing the speaker 110 can be easily changed by changing the design of the position of disposing only the sound emitting opening 416 in the lid 410 (design change of only the lid).
In the embodiment, as shown in FIG. 11, vibration regulating parts (ribs) 411 a, 412 a, 413 a, 414 a, and 415 a for regulating vibrations of the lid 410 (the vibration regulating part 414 a is not shown in FIG. 11) are formed in the bottom portion 411, top portion 412, side portions 413 and 414, and front portion 415 of the lid 410, respectively. Each of the vibration regulating parts is formed integrally with the lid 410 and has a projection shape which projects from the lid 410.
Since the vibration regulating parts (projections) 411 a, 412 a, 413 a, 414 a, and 415 a are formed in the lid 410, unnecessary vibrations of the lid 410 caused by sound vibrations (residual sound vibrations) of the speaker 110 are prevented and the sound quality can be improved.
On the outside of the side portion 413, as shown in FIG. 12, attachment parts 419 a and 419 b which are attached in correspondence with the bosses 201 a and 201 b of the speaker enclosure 310 and to which fittings such as screws are inserted are formed. Similarly, on the outside of the side portion 414, attachment parts 419 c and 419 d attached in correspondence with the bosses 201 c and 201 d, respectively, of the speaker enclosure 310 are formed.
In the side portion 414, a wire leading notch 401 for connecting a wire (not shown) from the speaker 110 to a predetermined control board (for example, a control board having a sound control circuit for generating a sound signal) is formed. Although the notch 401 is formed in the center of the side portion 414, for example, it may be formed in an arbitrary position between the fitting parts 419 c and 419 d.
In the embodiment, as shown in FIG. 14, the fitting portion which is fit to the speaker enclosure 310 in the lid 410 is formed in a stair shape. Concretely, the tip of the fitting portion in the lid 410 has steps, and the lower step comes into contact with the front end face of the fitting portion of the speaker enclosure 310. The step having a short distance between the front end face of the step in the fitting portion of the lid 410 and the front portion 415 of the lid 410 is set as a lower step.
For example, the portion 412 b fit to the speaker enclosure 310, in the top portion 412 of the lid 410 has a stair shape having a lower step 412 c and a higher step 412 d. Although a portion fit to the speaker enclosure 310, in each of the side portions 413 and 414 of the lid 410 is not shown in FIG. 14, the portion has a stair shape having a lower step and a higher step like the case of the fitting portion 412 b.
As shown in FIG. 14, a fitting portion 411 b fit to the speaker enclosure 310 in the bottom portion 411 of the lid 410 similarly has a stair shape having a lower step 411 c, a step 411 d higher than the step 411 c, and a step 411 e higher than the step 411 d. In this case, a recessed shape is formed by the steps 411 c, 411 d, and 411 e.
On the other hand, in the speaker enclosure 310, as shown in FIG. 15, fitting portions 311 b, 312 b, 313 b, and 314 b which fit to the lid 410 in the bottom portion 311, top portion 312, and side portions 313 and 314 of the speaker enclosure 310 are formed in a projected shape. FIG. 16 is a cross section of a main part of the speaker enclosure 310 seen from the direction B of FIG. 15.
In the case where the lid 410 is fit in the speaker enclosure 310, for example, the step 412 c in the fitting portion 412 b in the top portion 412 of the lid 410 shown in FIG. 14 comes into contact with a front end face 312 c of the fitting portion 312 b in the top portion 312 of the speaker enclosure 310 shown in FIGS. 15 and 16. The step 411 c in the fitting portion 411 b in the bottom portion 411 of the lid 410 shown in FIG. 14 comes into contact with the front end face 311 c of the fitting portion 311 b in the bottom portion 311 of the speaker enclosure 310 shown in FIG. 16. The front end face 313 c of the fitting portion 313 b in the side portion 313 of the speaker enclosure 310 shown in FIG. 16 comes into contact with a lower step (step 413 c shown in FIG. 11) in the fitting portion 413 b in the side portion 413 of the lid 410.
Next, the speaker enclosing box formed when the speaker enclosure and the lid are fit to each other will be described with reference to FIGS. 17 and 18.
In the embodiment, as shown in FIG. 17, the lid 410 (refer to FIG. 13) to which the speaker 110 is attached is fit to the speaker enclosure 310 (refer to FIG. 9), thereby forming a speaker enclosing box 510. In this case, the lid 410 is fit to the speaker enclosure 310 so that the opening in the lid 410 faces the opening 210 in the speaker enclosure 310, thereby forming the speaker enclosing box 510.
In the case where the lid 410 is fit to the speaker enclosure 310 as described above, as shown in FIG. 17, the bosses 201 a, 201 b, 201 c, and 201 d of the speaker enclosure 310 match the four attachment parts 419 a, 419 b, 419 c, and 419 d of the lid 410. Consequently, by screwing the fittings such as screws to the four bosses through the four attachment holes, the lid 410 is fixed to the speaker enclosure 310.
Moreover, in the case where the lid 410 is fit to the speaker enclosure 310, as shown in FIG. 18, the tip of the fitting portion 312 b of the speaker enclosure 310 overlaps the step 412 d in the fitting portion 412 b of the lid 410.
In a manner similar to the case of the fitting portion 312 b, the tips of the fitting portions of the side portions 313 and 314 of the speaker enclosure 310 also overlap higher steps (steps corresponding to the step 412 d in the fitting portion 412 b) in the fitting portion of the side portions 413 and 414 of the lid 410.
Further, the tip of the fitting portion 311 b of the bottom portion 311 of the speaker enclosure 310 is fit to the fitting portion 411 b having the recessed shape in the bottom portion 411 of the lid 410, so that it naturally overlaps the fitting portion 411 b.
FIG. 18 is a cross section showing a section of the speaker enclosing box 510 seen from the direction C of FIG. 17.
When the fitting portion formed in a stair shape in each of the bottom portion 411, top portion 412, and side portions 413 and 414 of the lid 410 is fit to the fitting portion formed in a projected shape in each of the bottom portion 311, top portion 312, and side portions 313 and 314 of the speaker enclosure 310, the inside of the speaker enclosing box 510 is sealed.
Obviously, when the lid 420 (refer to FIG. 5) to which the speaker 120 is attached is fit in the speaker enclosure 320 (refer to FIG. 7), in a manner similar to the case of the speaker enclosing box 510, a speaker enclosing box 520 having high sealing performance is formed.
FIGS. 19A and 19B shows a state in which the lid 410 to which the speaker 110 is attached and the lid 420 to which the speaker 120 is attached are fit to the body (in a state where attached parts are detached) 10 shown in FIG. 7 (the state in which the speaker enclosing boxes 510 and 520 are formed). FIG. 19A is a front view showing the front of the body 10, and FIG. 19B is a side view showing a side face of the body 10.
With the configuration of the speaker enclosing box described above, the following effects (1) to (6) can be expected.
(1) Since the body 10 and the two speaker enclosures 310 and 320 are integrally formed, the space of the amount of the speaker enclosures (the space corresponding to the thickness of the member of the speaker enclosure) in the case of forming the speaker enclosures 310 and 320 separately from the body can be assured. According to the space of the assured increase amount, the speaker enclosing box (speaker box) can be increased. Thus, a speaker enclosing box having large capacity under limit of the size of the gaming machine itself can be formed.
(2) Since the capacity of the speaker enclosing boxes 510 and 520 can be increased as described above, the quality of sound generated from the speakers 110 and 120 can be improved.
(3) As described above, the fitting portion between the lid 410 and the speaker enclosure 310 is formed in a stair shape, so that sealing performance of the inside of the speaker enclosing box can be increased. Moreover, the speaker enclosing box 510 having large capacity can be formed under limit of the size of the gaming machine itself.
(4) Since the fitting portion of the lid 410 and the speaker enclosure 310 is formed in a stair shape, the sealing performance of the speaker enclosing box when the lid is fit to the speaker enclosure can be increased. The sound quality can be further improved.
(5) Since the lid 410 and the speaker enclosure 310 are fit to each other by a recess and a projection, that is, the recess-shaped fitting portion of the lid 410 and the projection-shaped fitting portion of the speaker enclosure 310, the sealing performance in the speaker enclosure box can be further increased.
(6) When the lid 410 is fit to the speaker enclosure 310, the projected portion and the recessed portion are fit to each other. In particular, by engagement between the recess-shaped fitting portion 411 b in the lid 410 and the projection-shaped fitting portion 311 b in the speaker enclosure 310, the lid 410 is prevented from being easily tilted (dropped) forward (to the front) from the speaker enclosure 310. Consequently, the lid can be temporarily fixed to the speaker enclosure, and an assembling work (fixing) such as screwing can be performed easily.
Although the vibration regulating parts are provided on the inside of the speaker enclosure and also on the inside of the lid in the foregoing embodiment, the invention is not limited to the embodiment but may employ the following configuration.
The vibration regulating parts may be provided on the outside of the speaker enclosure and also on the outside of the lid.
With the configuration, unnecessary vibrations in each of the speaker enclosure and the lid caused by sound vibrations of the speaker can be regulated, so that sound quality can be improved.
In the case where the vibration regulating parts are provided on the inside of the speaker enclosure and also on the inside of the lid, however, as compared with the case of providing the vibration regulating parts on the outside of the speaker enclosure and also on the outside of the lid, the vibration regulating parts do not hinder members provided on the outside of the speaker enclosing box. In addition, the space in the speaker enclosing box can be effectively used. It is consequently more preferable to provide the vibration regulating parts on the inside of the speaker enclosure and on the inside of the lid.
Although the vibration regulating parts are provided for both of the speaker enclosure and the lid in the foregoing embodiment, the invention is not limited to the embodiment but may employ the following configuration.
For example, the vibration regulating parts are provided for the speaker enclosure or the lid. In the case where the vibration regulating parts are provided for the speaker enclosure, unnecessary vibrations of the speaker enclosure are regulated. On the other hand, in the case where vibration regulating parts are provided for the lid, unnecessary vibrations of the lid are regulated.
In the case where the vibration regulating parts are provided for the speaker enclosure or the lid, as compared with the case where no vibration regulating parts are provided for the speaker enclosure and the lid, the sound quality can be improved. However, in the case of providing the vibration regulating parts for the speaker enclosure or the lid, as compared with the case of providing the vibration regulating parts for both of the speaker enclosure and the lid, the sound quality may be lower. Consequently, it is more preferable to provide the vibration regulating parts for both of the speaker enclosure and the lid.
Further, the speaker enclosure and the vibration regulating parts provided for the speaker enclosure are integrally formed and the lid and the vibration regulating parts provided for the lid are integrally formed in the foregoing embodiment. However, the invention is not limited to the configuration but may also employ a configuration in which the speaker enclosure and the vibration regulating parts are formed separately, and the lid and the vibration regulating parts are formed separately.
Further, although the fitting portion of the lid is formed in a stair shape (the lower step and the higher step) and the fitting part of the speaker enclosure is formed in a projected shape in the foregoing embodiment, the invention is not limited to the embodiment but may be embodied as follows.
The fitting portion of the lid is formed in a projected shape and, on the other hand, the fitting portion of the speaker enclosure is formed in a stair shape.
With the configuration, when the fitting portion (projection) of the lid and the fitting portion (stair shape) of the speaker enclosure are fit to each other, the inside of the speaker enclosing box is sealed so that the sound quality can be further improved.
Further, in the foregoing embodiment, the fitting portion 411 b of the lid 410 is formed so as to have a recess and the fitting portion 311 b of the speaker enclosure 310 is formed so as to have a projection. However, the invention is not limited to the configuration but may employ the following configuration.
The fitting portion 411 b of the lid 410 is formed so as to have a projection, and the fitting portion 311 b of the speaker enclosure 310 is formed so as to have a recess.
With the configuration, by engagement between the projection-shaped fitting portion 411 b in the lid 410 and the recess-shaped fitting portion 311 b in the speaker enclosure 310, the lid 410 is prevented from being easily tilted (dropped) forward (to the front) from the speaker enclosure 310. Consequently, the lid 410 can be temporarily fixed to the speaker enclosure 310, and an assembling work (fixing) such as screwing can be performed easily.
Further, in the foregoing embodiment, the lid is fit to the speaker enclosure from the surface side of the body. The invention, however, is not limited to the embodiment but may employ the following configuration.
Specifically, as shown in FIG. 20, a lid 610 (a hatched portion in FIG. 20) is fit to the speaker enclosure 300 from the back side of the body 10.
In FIG. 20, in the speaker enclosure 300, for example, the lid 410 shown in FIG. 14 and the speaker enclosure 310 shown in FIG. 15 are formed integrally, and the rear portion 315 of the speaker enclosure 310 is open. Projection-shaped vibration regulators for regulating vibrations are formed in the portions corresponding to the lid 410 and the speaker enclosure 310.
Reference numerals 301, 302, and 303 denote vibration regulating parts (projections) corresponding to the vibration regulating parts 311 a, 312 a, and 313 a.
On the other hand, in the lid 610, fitting portions 611 and 612 which are fit to the speaker enclosure 300 are formed in a stair shape. The fitting portion 612 is formed so as to have a recess. In the lid 610, vibration regulating parts 613 and 614 each having a projected shape and regulating vibrations of the lid 610 are formed. The vibration regulating part 614 is a projection formed in the vertical direction (the direction from the fitting portion 611 to the fitting portion 612), and the vibration regulating part 613 is a projection formed in the lateral direction.
In this case as well, by fitting the lid 610 to the speaker enclosing member 300, a speaker enclosing box 600 having high sealing performance is formed and the sound quality can be improved.
Although the case of applying the present invention to a gaming machine in which a pachinko gaming machine itself is attached to a gaming stand has been described above, the invention is not limited to the case. The invention can be applied to various gaming machines such as a pachinko-slot gaming machine (slot machine), a “Jankyu (a kind of pachinko games)” gaming machine, a pinball, and various gaming machines set in a game arcade.
While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
