Description
~7~9375 BATTERY CASING FOR A PAGING RECEIYER
BACKGROUND OF THE INVE:NTION
The present inYention r&lates to an improYement in a battery casing for a paging receiver and other portable radios and, more particularly, to a motor mounting structure for a paging 5 receiYer in which a motor is installed for causing a housin~ of the receiver to vibrate to alert a user of ~he receiver to reception.
Generall~, a paging receiver is provided with a battery casing for accommodating a battery which is adapted to power 10 tha receiYer, the battery casing including a battery cover. A
printed circuit board to be electrically connected to both terminals of the battery is built in the housing of the receiver.
In relation to such a paging receiver, two different approaches are available for a person to be informed of reception, i. e., 15 generation of sound and vibration of a receiver housing. A
paging receiver with the vibration type alert scheme, there~ore, is further provided with a motor to cause the housing into vibration. Usually, a pagin~ recei~er with the sound type alert scheme is modified, or remodeled, into a pa~ing receiver with 20 the vibration type alert scheme accordi~g to user's requirement.
What is required for remodeling is removing a battery casing from a printed circuit board of the sound type receiver and, then, replacing it with an alternative battery casin~. While both o~ the battery casings, particularly their spaces for 25 accommodating batteries, are substa~tially iden~ical with each other, the battery used with the alternatiYe casing is smaller in capacity than that used with the other. For example, assuming that a UM 3 battery is accommodated in the original battery ~9375 casing, it is replaced with a UM 5 battery which is smaller in capacity and size than the UM 3 battery and, thereafter, a motor adapted for the vibration of the housing is placed in the remaining space of the battery casing and fixed in place by an 5 adhesive tape or the like. The printed circuit board of each of such two different types of paging receivers is provided with a read only memory (ROM) and a label indicatiYe of its function at the back and outside of the battery accommodating space of the battery casing.
A problem with the prior art procedure for the modification of the sound type receiver to the vibration type receiver is that it involves a substantial number of steps, i. e., removing thc original battery casing from the printed circuit board, mountin~
the alternative battery casing on the printed circuit board, and 15 reconnecting the alternative battery casing to the terminals of the printed circuit board. This results in poor maneuvabilitY
and a disproportionate number of structural eiements required.
Another problem is that the motor which is fixed in place by an adhesive tape is apt to be dislocated by shocks and impacts such 2 0 as when the receiver is let fall. Further, the difference in the size of a battery to be used as previously stated is an annoYance for a user while a UM 5 battery, for example, has only a limited service life and is not available as easily as a UM 3 battery depending upon the country. Still another disadvantage is that 25 when the battery cover is removed, the motor shows itself to degrade the appearance of the receiver. In addition, one cannot see the function label on the ROM unless he or she opens the housing to uncover the printed circuit board.
SUMI~ OF THE INVENTION
It is therefore an obiect of the present invention to enhance maneuvability and reduce the number of necessary parts ~vhen a paging receiver with the sound type alert scheme is modified into a paging rsceiver with the vibration type alert scheme.
It is another object of the present invention to provide an ~7~37~
improved battery casing for a vibration type pa~ing receiver which allows the use of a battery o~ the same capacity and size as a battery which is used with a sound type paging receiYer.
It is another object of the present invention to provide an 5 improved battery casing for a vibration type pa8ing receiver which holds a motor concealed in the casing when a battery cover is removed for the replacement of the battery.
It is another obiect of the present invention to provide an improved battery casing which allows a person to see a function 10 label bonded to a ROM on a printed circuit board by merely removing a battery cover.
It is another object of the present invention to ~rovide a generally improved battery casing for a paging receiver.
A battery housing structure for a paging receiYer which has 15 a function of alerting a person to reception by causin~ a motor to Yibrate a housing of the receiver of the present invention comprises a battery container for accommodating a battery. a generally box-like motor receiving portion provided on an outer side periphery of the battery container and having a recess 2 0 which is complementary in shape to the motor, and a cover fastened to the motor receivin~ portion while covering the motor which is placed in the motor receiving portion, thsreby fixing the motor to the motor receiving portion.
The above and other objects, features and advantages of the 25 present invention will become more apparent from the followin~
detailed description taken with the accompanyin~ drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
To better understand the present inYention, a brief reference will be made to a prior art paging receiver, shown in Fig. 1.
Generall~, the prior art paging receiver 10 comprises a housing 12 and a battery cover 1d~ which forms a part of the housing 12 and is associated with a battery casing.
Fig. 2 shows a batterY casing of a paging receiver which generally appears as shown in Fig. 1 and is constructed to alert a user to reception by sound, a housing of the receiver being removed in the drawing. The battery casing, generally 2 0, is made up of a printed circuit board 22, and a batterY container 24 which is mounted on the printed circuit board 22 for 2 5 accommodating a battery 2 6 . The battery container 2 4 is provided with a positive terminal 28 and a negative terminal 30.
A ROM 32 to which a label 34 is bonded adjoins the outside of the battery container 24 opposite to the battery receiving space.
The reference numeral 3 6 designates a metal îittinX adapted to 3 0 fasten the housing 1~ and printed circuit board 2 2 together.
Fig. 3 shows in an external view a battery casing o a pa~in~
receiver of the type which informs a person of reception by the vibration of a housing of the receiver, a housing of the receiver bein8 removed for clarity. In Fig. 3, the same or similar structural elements as those shown in Fig. 2 are desiglla-ed by , .~

like reference numerals. In the battery casing 20a of Fig. 3, a motor 38 is accommodated and fixed in place by an ~dhesive tape 39.
Assume that the user of the sound type paging receiver 20 5 desires to modifY it into the vibration type receiver 20a. The user removes the battery container 24 of Fig. 2 from the printed circuit board 22 and, then, mounts a battery container 24a which is configured to accommodate the motor 38, as shown in Fig. 3. The battery container ~4a has the motor 38 fixed 10 therein by the adhesive tape 39 and is provided with a negative terminal 30a adiacent to the motor 38. A batterY 26a which is smaller than the battery 26 is used with the battery casing of Fig. 3. For example, when the battery 26 is a UM 3 battery, the battery 26 a is a UM 5 battery. The ROM 32 is located 15 adjacent to the side periphery o~ the battery container 24 or 24a which is mounted on the board 22. The positive terminal 28 and negative terminal 30 or 30a of the battery container 24 or 24a are soldered to the board 22, whereby the battery container 24 or ~4a is fixed in place. The metal fitting ~6 is soldered to the 20 board 22 in order to rigidlY connect the housing 12 to the board 2~.
As previouslY stated, the prior art procedure for the modification of the sound type paging receiver 20 into the vibration type receiver 20a has various drawbacks. Removing 25 the battery container 24 from the printed circuit board 22 and, then, mountin~ the other battery container 24a while replacing the tarminal 30 is not only time- alld labor consuming but also disproportionate in the number of necessary parts~ 3ne cannot see the function label 34 on the ROM 32 unless he or she opens 30 the housing 12 to let the board 22 show itself. Besides, the battery container 24 has to be replaced with the battery container 24a and, because the metal fitting 36 is soldsred to the board 22 independently of the battery container 24, the battery container 24a is fixed merely by soldering the terminals 2B and 35 30a and, therefore, unstable in poiition relative to the board , .

Referring to Figs. 4 to 8, a battery casing for a pagin~
receiver embodying the present invention is shown which is ~ree from the drawbacks inherent in the prior art structure aS
discussed above. The pagin~ receiver, generally 40, to which the present invention is applied is capable of notifying a user of reception by sound and the vibration of a housing selectively.
As shown in Fig. 4, the receiver 4 0 generally comprises a housing 42 and a battery cover 44 which forms a part of the housing 42. The battery cover 44 may be pulled as indicated by an arrow so as to remove it from the housin~ 42. Installed in the housing 42 and battery cover 44 is a battery casing 46 as shown in Fig. 5 . The battery casing 4 6 includes a battery container 50 which is mounted on a printed circuit board 48 to receive a battery 5 2 therein. The battery container 5 0 is provided with a motor receiving portion 56 adapted to mount a motor 54. Specifically, the motor receiving portion 56 is molded integrally with the outer periphery of the battery container 5 0 and provided with a generally box-like coni~uration, which includes a semicircular recess 58 complementary to the shape of the motor 54. A cover 60 is adapted to fix the motor 54 within the motor receiYing portion 56 from the above and also provided with a semicircular configuration ~hich is complementary to the shape of the motor 54. The cover 60 may be implemented with a thin sheet metal by way of example. The cover 60 is formed with a pawl 64 at one end thereof which is capable of mating with a notch 62 provided at the bottom of one side of the motor receiving POrtiOn 56. At the other end, the covcr 60 is formed with a tongue 72 which is used to fasten by a tapping screw 70 tbe cover 6û to a threaded hole 68 of a fixing portion 66, which is provided between the battery container 5 0 and the motor receiving portion 56.
In the above construction, to fix the motor 54 received in the portion 56 in place, the cover 60 is placed on the motor 54 from above the motor 54, then the pawl 64 of the cover 60 is ~;~7~37~
mated with the notch 62 of the portion 56, and then the ton~:ue 7 2 of the cover 60 is fastened to the fixing portion 66 by the screw 70. This maintains the motor 54 ~ixed firmly in the portion 56. Further, as shown in Figs. 5 and 6, a cushioning member 74 made o sponge or the like is laid in the recess S8 o~
the portion 56 so as to preYent the motor 54 from being dislocated or otherwise effected by shocks and impacts.
Electrical connection between the motor 54 and the printed circuit board 48 is set up by soldering terminals 78 of the rnotor 54 to terminals 76 which are connected to the printed circuit board 48.
As shown in Figs. 5 and 7, the battery casing 50 is provided with a projection 82 in a part of its side wall and alon~ the ROM
80 which adjoins the side wall of the battery container 50. The battery container 5 0 is made of a semitransparent material so that the label 84 on the ROM 80 may be seen from the outside merely by removing the battery coYer 44.
Further, as shown in Figs. 5 and 8, the battery container 50 is formed with a generally box-like proiection 86 in a par~ of its outer periphery, while a flat metal fitting 88 is press-fitted in the projection 86. Specifically, the metal fitting 88 is provided with a threaded opening 88a at its center and a tongue 88b at its lower end. The to~gue 8 8b is inserted in an opening of the printed circuit board 48 and, then, soldered thereto, whereb~
the metal fitting 8 8 is fixed in place to in turn îix the battery 2S casing 50 to the board 48. A screw 90 with which the housing 42 is provided beforehand is driYen into tha metal fitting 8~ to rigidly connect the board 48 and the housing 42 to each other.
It is to be noted that the metal fitting 8 8 is physically independent of a positive terminal, not shown, since moldin~
3 0 them together would cause an antenna which is built in the receiYer to be effected with respect to the electric field, resulting in the deterioration of sensitivity.
In summary, in accordance with this embodiment, a battery casing is molded at its outer periphery with a motor recei~lring 3 5 portion which is provided with a semicircular recess 37~
complementary to the shape of a motor. The motor which is placed in the receiYing portion is secured by a semicircular co~er which is also complementary in shape to the motor. This allows a sound type receiver to be remodeled into a ~ibration type 5 receiYer without resorting to the replacement of a battery casing, while making it possible to mount the motor by fastening onlY-When a battery coYer is removed for the replacement of a battery, the motor remains concealed so that the receiver 10 appears pleasant to the eye. In addition, it is needless for a user to replace the battery depending upon the alerting system, i. e. the sound type alert system or the vibration type alert sYstem.
Because the battery container is made of a semi-transparent l S material and because the side wall of the battery container is partly protruded complementary to the shape of a ROM, a function label which is bonded to the ROM can be seen with ease merely by removing the batterY cover.
Another ad~antage attainable with the em~odiment shown 2 0 and described is that the battery container can be fixed to a printed circuit board by press-fitting a flat metal fitting with a threaded hole in a ~enerallY box-like projection of the battery container and, then, solderin$ it to the board.
Various modifications will become possible for those skilled 25 in îhe art after receiYing the teachings of the present disclosure without departing ~rom the scope thereof.

the metal fitting 8 8 is fixed in place to in turn îix the battery 2S casing 50 to the board 48. A screw 90 with which the housing 42 is provided beforehand is driYen into tha metal fitting 8~ to rigidly connect the board 48 and the housing 42 to each other.
It is to be noted that the metal fitting 8 8 is physically independent of a positive terminal, not shown, since moldin~
3 0 them together would cause an antenna which is built in the receiYer to be effected with respect to the electric field, resulting in the deterioration of sensitivity.
In summary, in accordance with this embodiment, a battery casing is molded at its outer periphery with a motor recei~lring 3 5 portion which is provided with a semicircular recess 37~
complementary to the shape of a motor. The motor which is placed in the receiYing portion is secured by a semicircular co~er which is also complementary in shape to the motor. This allows a sound type receiver to be remodeled into a ~ibration type 5 receiYer without resorting to the replacement of a battery casing, while making it possible to mount the motor by fastening onlY-When a battery coYer is removed for the replacement of a battery, the motor remains concealed so that the receiver 10 appears pleasant to the eye. In addition, it is needless for a user to replace the battery depending upon the alerting system, i. e. the sound type alert system or the vibration type alert sYstem.
Because the battery container is made of a semi-transparent l S material and because the side wall of the battery container is partly protruded complementary to the shape of a ROM, a function label which is bonded to the ROM can be seen with ease merely by removing the batterY cover.
Another ad~antage attainable with the em~odiment shown 2 0 and described is that the battery container can be fixed to a printed circuit board by press-fitting a flat metal fitting with a threaded hole in a ~enerallY box-like projection of the battery container and, then, solderin$ it to the board.
Various modifications will become possible for those skilled 25 in îhe art after receiYing the teachings of the present disclosure without departing ~rom the scope thereof.
