SUMMARY OF THE INVENTION
The above and other disadvantages of prior art arcade gun amusement devices are overcome by the present invention of an amusement game comprising a target, a plurality of balls, an operator fired gun for shooting the balls toward the target, means for automatically returning the balls from the target to the gun, means for automatically loading one ball at a time into the gun for firing, and wherein the gun has a breech for receiving each ball as it is loaded into the gun, a breech door, and the automatic ball means load the balls from below into the gun breech, and further including a resilient finger mounted on the breech door for imparting a rotational force to each ball upon loading, while simultaneously deflecting each ball to contact the top, interior portion of the gun breech, to cause `- mb/JL~ ~ 3 ~
" ~g35~8 the ball to spin into the gun breech, whereby each ball is caused to positively roll itself into the gun breech by rotational inertia, upon loading.
In the preferred embodiment of the invention,t the gun is gimballed such that the gun has limited movement about vertical and horizontal axes so as to allow the gun to be accurately aimed by the player.
The balls are loaded from beneath the gun along the t horizontal and vertical axes of movement of the gun.

35!!~&1 DET~ILED DESCRIPTION OF A PREFERRED EMsODI~NT
~ ~eferring now more particularly to FIG. 1, the amuse-ment gun device 10, according to the invention, is illustrated.
The gun 12 is pivotally mounted ln a console 11 so that it may be pivoted about both a horizontal and a vertical axis to aim the yun. The operator controls the firing of the gun through a push button switch 28 on a pair of handles on the gun. Upon firing, the gun lobs a rubber ball 14 toward a target 16. The target 16 is inclined and includes a plurality of ball re-10 ceiving receptacles of varying diameters 18. Each of the ball ~;
receiving receptacles is connected to a passageway 20 in the bottom of the game which allows the balls to return under the force of gravity to the player area at the console 11. A motor driven belt lift mechanism 22 raises the balls from the bottom of the game to the top of the console area where they are stored in a curved, horizontal rack 24 for automatic reloading into the gun 12, as will be e~plained in greater detail hereinafter.
Referring now more particularly to FJGS. 2, 3 and 8, ~-the mechanism by which the returned balls are loaded into the gun will be explained. The balls 14, as mentioned above, return down the return tube 20 to the base of a lift belt 22.
The belt 22 is rotated by an electric motor 48 which is under the control of a photo optic sensor 50 mounted across the upper, horizontal ball return passage 24. As long as the photo optic sensor 50 does not sense the presence of any balls, the motor 48 causes the belt 22 to lift the balls upwardly and deposit them at the mouth of the curved chute 24. As soon as the balls have backed up to the point where they block the photo optic sensor 50, ~he motor 48 is shut down. I~ will be ik/Gb l ,j ~6~93 1¦ appreciated that the motor 48 is connected to an external 2 source of powex (not shown) through a switch 52 which is 3 ! controlled by the photo optic sensor 50.
4 The belt 22 has a plurality of projecting fingers 54 .5¦ which support the balls during thellifting operation. The i 61 balls are retained over the fingers 54 by means of a verticàl 7 ¦ sleeve 56 which surrounds one side of the belt 22.
8 I The sloping chute 24 leads the balls to the openi~g 9 ¦ of a horizontal ball passage 32, as best shown in FIG. 3.

35!!~&1 DET~ILED DESCRIPTION OF A PREFERRED EMsODI~NT
~ ~eferring now more particularly to FIG. 1, the amuse-ment gun device 10, according to the invention, is illustrated.
The gun 12 is pivotally mounted ln a console 11 so that it may be pivoted about both a horizontal and a vertical axis to aim the yun. The operator controls the firing of the gun through a push button switch 28 on a pair of handles on the gun. Upon firing, the gun lobs a rubber ball 14 toward a target 16. The target 16 is inclined and includes a plurality of ball re-10 ceiving receptacles of varying diameters 18. Each of the ball ~;
receiving receptacles is connected to a passageway 20 in the bottom of the game which allows the balls to return under the force of gravity to the player area at the console 11. A motor driven belt lift mechanism 22 raises the balls from the bottom of the game to the top of the console area where they are stored in a curved, horizontal rack 24 for automatic reloading into the gun 12, as will be e~plained in greater detail hereinafter.
Referring now more particularly to FJGS. 2, 3 and 8, ~-the mechanism by which the returned balls are loaded into the gun will be explained. The balls 14, as mentioned above, return down the return tube 20 to the base of a lift belt 22.
The belt 22 is rotated by an electric motor 48 which is under the control of a photo optic sensor 50 mounted across the upper, horizontal ball return passage 24. As long as the photo optic sensor 50 does not sense the presence of any balls, the motor 48 causes the belt 22 to lift the balls upwardly and deposit them at the mouth of the curved chute 24. As soon as the balls have backed up to the point where they block the photo optic sensor 50, ~he motor 48 is shut down. I~ will be ik/Gb l ,j ~6~93 1¦ appreciated that the motor 48 is connected to an external 2 source of powex (not shown) through a switch 52 which is 3 ! controlled by the photo optic sensor 50.
4 The belt 22 has a plurality of projecting fingers 54 .5¦ which support the balls during thellifting operation. The i 61 balls are retained over the fingers 54 by means of a verticàl 7 ¦ sleeve 56 which surrounds one side of the belt 22.
8 I The sloping chute 24 leads the balls to the openi~g 9 ¦ of a horizontal ball passage 32, as best shown in FIG. 3.
The balls are caused to enter the passage 32 by means of a
11 pneumatia actuator 30 which ejects a plunger upon the application
12 1 of a control signal. The plunger of the actuator 30 pushes one
13 ¦ ba~11 at a time into the entrance of the passaae 32. As best
14 ¦ shown in FIG. 5, the passage 32 terminates in a vertical lS passage 34 to forrn a right angle elbow. At the botto~ of the 16 elbow is disposed a pneumatic actuator 36 which raises a 17 plunger 37 to lifl: one ball 14 at a time up into the breech 58 18 of the gun.
1~¦ Referring now more particularly to FIGS. 4, 6 and 10, 20¦ the operation of :Loading the ball 14 into the breech 58 ~ill be 21¦ described in greater detail. Because the plunger 37 only 22 ¦ travels a portion of the way up the vertical passage 34, it 23 ¦ does not literally push the ball into the breech 58 but sim~ly 24 ¦ propels the ball upward with sufficient velocity so that the ball's inertia ~ Ll caxry it upward until it strikes the 26 interior surface of the open breech door 38. ~ore particularly, 27 as best shown in FIG. 10, the ball 14 first strik~s an in~ardly 28 bent, bottom portion 62 of a curved spring deflector 60 fastened 29 to the interior st~rface of the breech door 38. The impact of 301 the ball 14 on the bottom portion ,62 causes the ball 14 to begi~
311 ., .
3S9~ 1 1¦ rotating in a counter-clockwise direction, as vie~led in FIG. lO.
21 As the ball continues its travel upwardly, it collides with an 3 , arcuately curved, top portion 64 o~ the deflector 60, causin~ it 4 I to elastically deflect towards the surface of the breech door 38. ¦
5 I This arcuately curved portion 64 co~tinues its deformation ul~til 6 I it meets with a correspondingly curved stop 66 on the breech 7 ! door 38 near the top o~ the breech door. At this point, the 8 ¦ deflector 60 no longer deflects and the ball is caused to ~ebo~nd 9 into the breech 58 where it strikes the top surface of the breech.¦
As soon as the spinning hall hits the top surface of the brçech 11 58, it rolls itself into the breech and then rebounds downwardly 12 to the bottom surface of the breech where its forward momentu~ is 13 stopped because the collision of the rotating ball with the bGttom 14 surface of the breech 58 tends to pull ~he ball backwards against lS the forward momentum of the ball. The net result is that the ball 16 simply stops all motion at this point in the breech. The ba'l is 17 prevented from rolling out of the breech by the deflector 60 18 which has now resiliently snapped back to its original position.
19 ~s will be explained in greater detail hereinafter, the control system for the breech door actuator 40 is timed such that the 21 breech door 38 is immediately caused to be closed, thereby 2~ holding the ball 14 within the breech. Co~pressed ai~ is then 23 supplied to the sealed breech throuyh a pneumatic hose 68 ~itted 24 into the breech door 38 and connected to a source of compressed 2~ ~ir. -26 The door actuator 40 has an extendible plunger 70. The 27 en~ of ~he ~lunger 70 is pivotally connccted to a ~rackct ~2 28 attached to the door 38. The breech door 38 is pivoted about 29 a hin~e 74 to the casting which constitute~ the breech 58.
~s previously mentioned, the gun h~s a limited decJree 31 I ;
32 , 11 of movement about both a vertical and a horizontal axis. The 2¦ gun has an outer shellor casting 76 which supports or is atkached j 3 I to all of the gun components either directly or indirectly. This j 4 ¦casting76 terminates at its lower end in an inwardly extending, annular flange 78 which is support~d on a cylindrical,flat 6 member or table 80.

Because the plunger 37 only 22 ¦ travels a portion of the way up the vertical passage 34, it 23 ¦ does not literally push the ball into the breech 58 but sim~ly 24 ¦ propels the ball upward with sufficient velocity so that the ball's inertia ~ Ll caxry it upward until it strikes the 26 interior surface of the open breech door 38. ~ore particularly, 27 as best shown in FIG. 10, the ball 14 first strik~s an in~ardly 28 bent, bottom portion 62 of a curved spring deflector 60 fastened 29 to the interior st~rface of the breech door 38. The impact of 301 the ball 14 on the bottom portion ,62 causes the ball 14 to begi~

21 As the ball continues its travel upwardly, it collides with an 3 , arcuately curved, top portion 64 o~ the deflector 60, causin~ it 4 I to elastically deflect towards the surface of the breech door 38. ¦
5 I This arcuately curved portion 64 co~tinues its deformation ul~til 6 I it meets with a correspondingly curved stop 66 on the breech 7 ! door 38 near the top o~ the breech door. At this point, the 8 ¦ deflector 60 no longer deflects and the ball is caused to ~ebo~nd 9 into the breech 58 where it strikes the top surface of the breech.¦
As soon as the spinning hall hits the top surface of the brçech 11 58, it rolls itself into the breech and then rebounds downwardly 12 to the bottom surface of the breech where its forward momentu~ is 13 stopped because the collision of the rotating ball with the bGttom 14 surface of the breech 58 tends to pull ~he ball backwards against lS the forward momentum of the ball. The net result is that the ball 16 simply stops all motion at this point in the breech. The ba'l is 17 prevented from rolling out of the breech by the deflector 60 18 which has now resiliently snapped back to its original position.
19 ~s will be explained in greater detail hereinafter, the control system for the breech door actuator 40 is timed such that the 21 breech door 38 is immediately caused to be closed, thereby 2~ holding the ball 14 within the breech. Co~pressed ai~ is then 23 supplied to the sealed breech throuyh a pneumatic hose 68 ~itted 24 into the breech door 38 and connected to a source of compressed 2~ ~ir. -26 The door actuator 40 has an extendible plunger 70. The 27 en~ of ~he ~lunger 70 is pivotally connccted to a ~rackct ~2 28 attached to the door 38. The breech door 38 is pivoted about 29 a hin~e 74 to the casting which constitute~ the breech 58.
~s previously mentioned, the gun h~s a limited decJree 31 I ;

The 2¦ gun has an outer shellor casting 76 which supports or is atkached j 3 I to all of the gun components either directly or indirectly. This j 4 ¦casting76 terminates at its lower end in an inwardly extending, annular flange 78 which is support~d on a cylindrical,flat 6 member or table 80. As best shown in FI~. 7, the casting76.may 7 be pivoted abou~ a vertical axis which is co-~xial with the 8 axis of symmetry 35 of the vertically extending passage 34. T~e 9 degree of pivotal movement about this vertical axis is controlled by t~o projecting pins 82 which are circumferentially spaced on ;
11¦ the casing 76 from an outer sleeve 84 which is co-axial with the 12 horizontal pipe or passage 32. This co-axial pipe 84 rotates 131 inlhorizontal yokes 86 which are bolted to a stationary framc 14¦ ~8 of the entire console. In this manner, the gun is also

The scoring console includes a score indicator 27 such as an LED display or a lamp field, or ~, ll ¦ an electro-mechanical indicator or the like.

22¦ Referring now more particularly to FIG. ll~, the game 23 ¦ is initially actuated when the player deposits a coin in the 241 coin slot 26, thereby closing a switch 94 which supplies a 251 ground connection ~logic low) over a lead 96 to one input of a 26¦ flip-flop circuit 98.

2I The output signal on the lead 100 is also supplied 3I through a transistor 110 to the microprocessor (not shown) 41 via leads 112 and 114. The "game on" signal consists of a logic sl high which, in this circuit, is th~ equivalent of a positivei ~-61 going voltage. A correspcnding logic low output signal fro~
7 ¦ the flip-flop 98 is obtained over a lead 116 when the game is 8 ¦ initially activated. This logic low over the lead 116 is 9 ¦ supplied to one input of an inverted OR gate 118 whose 10 I output is supplied to a re-set bus 120. j ~ , 11 I Before the game can begin, it is necessary to determine 12 I that the gun is not jammed. To this end, the jammed gun sensor 13 ¦ 92~ which is a photo optic sensor, supplies an output signal 14 ¦ via a ~ead 122 to one input of an .inverted ~ID gate 124. The 15 ¦ inverted output o the AND gate 124 is supplied to one input 16 ¦ of an ~ND gate 126. The inverted output of the AND gate 126~is 17 ¦ supplied via a lead 128 to one input of the inverted OR gate 118.
18 ¦ From the schemmatic diagram it can be seen that the output on 19 ¦ the lead 123 in the absence of a gun jam will be a logic low 20 ¦ and thus the output of the inverted OR gate 118 will be a logic 21 ¦ high.
22 ¦ Since the gun is loaded and ready to fire'before the 23 ¦ coin slot switch '34 is actuated, the actuation of ~he switch 94 24 ¦ enables the game to be played in the absence of a gun jam signal.
2~ ¦ The gun is fired ~hen the player depresses the gun trigger 26 ¦ switch 28 which sends a logic low to one input of a NAND gate 27 ¦ ~30. The output of the N~ND gate 130 is fed to the nega~i~e 28 going inpu~ of a multivibrator 13~. It can be seen that the 29 dep ssion of the trigger switch 128 ca~ses a logic hlqh to be 32 ' -13 l~

delivered from the output of the NAND gate 130 to the input of the mul~ivibrator 132.
This causes the multivibrator 132 to be triggered sucn that a rising squarewave output signal appears at one output ~ead 134 of the multivibrator 132 and a negative going square-wave to appear at another output lead 136 of the multi-vibrator 132. The lead 134 constitutes a bus which supplies ~ontrolling signa.ls to the actuators 44, 40, 30 and 36 and a ball count signal to the microprocessor via leads 153.
By counting the number of fired balls the microprocessor can determine when to generate a "game over" signal to shut off the gamer The negative going signal on lead 136 is supplied through a transistor switch amplifier 138 to a relay or valve actuator 140 which releases a volume of compressed air into the gun breech to fire the gun. Simultaneously, the positive going signal on lead 134 is supplied to the negative going inputs of a series of multivibrators associated with the other actuators, as will be explained in greater detail hereinafter.
The negative going signal on the lead 136 is supplied to an .:
inverted input to still another multivibrator 142. The multlvibrator 142 supplies a delay signal which is sufficiently long to ensure that the gun has been reloaded before it is again fired~ An output signal in the form of a negative going ~`
pulse is supplied via lead 144 to the other input of the inverted AND gate 124 and to one i.nput of a NAND gate 146. The lead 144 is also connected to one input of an inverted AND
gate 148 whose output is fed to the other input to the multi-vibrator 98. The other input of the inverted AND gate 148 is JK o~ .
10~3598 1 ¦ supplied through a photo optic coupler 150 from the microprocessor 2 ¦ (not shown) over leads 152. The microprocessor sends the "game 3 ¦ over" signal through the leads 152 and the photo optic coupler, 4 150 to the input of the invert~d AND gate 148. The reason for. ~
the photo optic coupler 150 is to e~liminate the possibility Qf ~' 6 ground loops and thus isolate the microprocessor from the ~!
7 game controi circuitry. The output from the photo optic coupler 8 150 to the input of the inverted ~D gate 148 is normally a 9 logic low ~7hile the game is on and is a logic high when the 10 game~is over. Thus, the signal supplied via the lead 144 I , ll simultane,ously with ~he "game over" ~ignal will cause the 12 flip-flop 98 to be re-set and the game to be stopped, as will 13 be~explained in greater detail hereinater. , 14 Referring now more particularly to FIG. llB, it will be 15 I seen that the positive going output pu].se from the multivibrator 16 ¦ 132 upon the firing of the gun is supp].ied via the bus 134 to 17¦ the input of a multivibrator 154 whose output is supplied 'hrough 18 ¦ a transistor amplifier 156 to energize the recoil actuator 44 19 ¦ through a valve or relay 44'. As will be noted from the ' 20 ¦ waveform diagram of PIG. 9, this reccil ta~;es place immedia~ely 21 ¦ after the cessation of the positive going pulse from the output 22 ¦ of the multivibrator 132, that is in~mediately afte~ t~e firing ~`

A second output from the multivibrator 158 is supplied 6 to trigger a multivibrator 162 whose output is coupled through 7 a transistor amplifier 164 to a relay or valv~,30' of the 8 horizontal input injector actuator 30. This enSUres that a 9 ball will be moved through the horizontal passage 32 only after ¦
10 ¦the hreech door has been first opened and then closed.
11 ¦ The output signal via the lead 134 is also supplied 12 to the input of the multivibrator 166 whose output is 13 s~plied to a second multivibrator 168 whose output is coupled 14 ¦through a transistor amplifier 170 to a relay or ~alve 36' for 15 ¦ the breech injector actuator 36. The purpose of having the two 16 ¦ multivibrators 166 and 168 is to interpose a finite delay to 17 ¦ allow the breech door 38 to be fully opened before the breech 18 ¦ injector actuator 36 raises a ball vertically in the passage 34 19 I into the breech.

22 ¦ Referring again to FIG. llA, when the gun,jams, a logic 231 high signal is supplied via the lead 122 to the inverted A~D
241 gate 124. Prior to depressing the trigger switch 28, the stat~s 25¦ of the lead 144 will be a logic high. The output of the inverte~

61 inoperable for the duration of the signal. This logic low ~, 71 signal via the lead 120 is also supplied to th'e input of a 81 NAND gate 172 whose other input is connected to the lead 128.
91 The output of the N~JD gate 172 is supplied as one input to an 10¦ inverted AND gate 174. The other input to ~he inverted AND ; .
11¦ gate 174 is a logic high. The output of the lnverted ~ND gate 12¦ 174 is supplied to the inverted re-set input to the multivibrator 13¦ 13~, Whenever the output of the inverted AND gate 174 is a 14¦ logic low, the multivibrator 132 will be rendered inoperable.
~¦ This condition will exlst whenever both of the inputs to the 161 NAND gate 172 are simultaneously logic lows. Thus, a jammed 17¦ gun sensor signal will not disable the multivibrator 132 but 18¦ will disable all of the remaining multivibrators so that the 19 ¦ gun will be fired each time the trigger is pulled but no new 20¦ balls will be loaded into the breach nor will the breech door 211 be opened, nor will recoil take place. 1 22¦ In a similar manner, when the "game over"'input signal 23 is received from the microprocessor along the leads 152, the 24 input via the lead 116 to the NOR gate 118 is a logic high ;, 25 I because the flip-10p 98 has been re-set.

Thus, the signal supplied via the lead 144 I , ll simultane,ously with ~he "game over" ~ignal will cause the 12 flip-flop 98 to be re-set and the game to be stopped, as will 13 be~explained in greater detail hereinater. , 14 Referring now more particularly to FIG. llB, it will be 15 I seen that the positive going output pu].se from the multivibrator 16 ¦ 132 upon the firing of the gun is supp].ied via the bus 134 to 17¦ the input of a multivibrator 154 whose output is supplied 'hrough 18 ¦ a transistor amplifier 156 to energize the recoil actuator 44 19 ¦ through a valve or relay 44'. As will be noted from the ' 20 ¦ waveform diagram of PIG. 9, this reccil ta~;es place immedia~ely 21 ¦ after the cessation of the positive going pulse from the output 22 ¦ of the multivibrator 132, that is in~mediately afte~ t~e firing ~`
2~1 has ceased. This is accomplished because the multivibrator 154 ~4¦ is triggered on the negative going edge of the output pulse from 25 ¦ the multivibrator 132. "

1¦ Similarly, the outpu~ on lead 134 is 2 fed to the input of a multivibrator 158 whose output is supplied 3 through a transistor amplifier 160 to a relay or valve 4 ¦actuator 40' to energize the actuator 40 which opens the breech 5 ¦door. A second output from the multivibrator 158 is supplied 6 to trigger a multivibrator 162 whose output is coupled through 7 a transistor amplifier 164 to a relay or valv~,30' of the 8 horizontal input injector actuator 30. This enSUres that a 9 ball will be moved through the horizontal passage 32 only after ¦
10 ¦the hreech door has been first opened and then closed.
11 ¦ The output signal via the lead 134 is also supplied 12 to the input of the multivibrator 166 whose output is 13 s~plied to a second multivibrator 168 whose output is coupled 14 ¦through a transistor amplifier 170 to a relay or ~alve 36' for 15 ¦ the breech injector actuator 36. The purpose of having the two 16 ¦ multivibrators 166 and 168 is to interpose a finite delay to 17 ¦ allow the breech door 38 to be fully opened before the breech 18 ¦ injector actuator 36 raises a ball vertically in the passage 34 19 I into the breech. This delay is supplied by the ~ultivibrator~166 20 ¦ whereas the multivibrator 168 determines how long the valve to 21 ¦ the actuator 36 remains open.
22 ¦ Referring again to FIG. llA, when the gun,jams, a logic 231 high signal is supplied via the lead 122 to the inverted A~D
241 gate 124. Prior to depressing the trigger switch 28, the stat~s 25¦ of the lead 144 will be a logic high. The output of the inverte~
26 ¦ AND gate 124 will therefore be a lDgic high and the output of 27 ¦ the AND gate 126 will also be a logic high. This will caulse the 28 ;' 301 , ' .

1093~98 1 I output of the NOR gate 118 to be a logic low. Once a logic low 2 ¦ appears on the re-set bus lead 120, all of the multivibrators 142, 154, 158, 162, 166 and 168 are supplied with a re-set 41 signal (which enters the multivibrators as a logic high because 51 it is supplied to their inverting ~nputs) which renders themj ;~
61 inoperable for the duration of the signal. This logic low ~, 71 signal via the lead 120 is also supplied to th'e input of a 81 NAND gate 172 whose other input is connected to the lead 128.
91 The output of the N~JD gate 172 is supplied as one input to an 10¦ inverted AND gate 174. The other input to ~he inverted AND ; .
11¦ gate 174 is a logic high. The output of the lnverted ~ND gate 12¦ 174 is supplied to the inverted re-set input to the multivibrator 13¦ 13~, Whenever the output of the inverted AND gate 174 is a 14¦ logic low, the multivibrator 132 will be rendered inoperable.
~¦ This condition will exlst whenever both of the inputs to the 161 NAND gate 172 are simultaneously logic lows. Thus, a jammed 17¦ gun sensor signal will not disable the multivibrator 132 but 18¦ will disable all of the remaining multivibrators so that the 19 ¦ gun will be fired each time the trigger is pulled but no new 20¦ balls will be loaded into the breach nor will the breech door 211 be opened, nor will recoil take place. 1 22¦ In a similar manner, when the "game over"'input signal 23 is received from the microprocessor along the leads 152, the 24 input via the lead 116 to the NOR gate 118 is a logic high ;, 25 I because the flip-10p 98 has been re-set. This will produce 26 ¦ a logic low output signal from the NOR gate 118 which will 27 ¦ also prevent any of the multivibrators from operating. Molreover, 28 ¦ because the signal appearing on t~le lead 128 is also a logic 29 ¦ low, the ou~put of the N~ND gate 17~ will be a logic high and
30 ¦ the output of the inverted AND gate 174 will be a logic low
31 I ;
32 I , ~ -17~ , ~3S~8 1¦ whic~ results in the multivibrator 132 also beincJ disabled.
21 Since it is difficult to tune each game ~o operate at an ¦
31 identical firing rate when it is desired to operate a plurality ¦
4¦ of the gun amusement devices in compe~ition, it is necessary to 5¦ ensure that the firing rates of al~ of the guns doe not exce~d a ;~-6¦ certain standardized rate in order to render the guns co~pe~itive.
71 To this end, the arcade operator can supply a'squarewave input 8¦ from an external generator (not shown) via leads 176 to a ~hotio 9 ¦ OptlC coupler 178 whose output is supplied to one input of the 10¦ N~D gate 146. The other input of the N~D gate 146 is ;
11¦ supplied via lead 144. It will be remembered that the function 12 ¦ of the output of the NAND gate 146 is to block further actuation t 13 ¦ up~n the depression of the trigger switch 28 until reloading s 14¦ completed. By supplying a squarewave input si~nal to the other 1~1 input to the NA~D gate 146 the same result can be achieved, 16¦ namely that the various guns which are simultaneously suppli~d 17 ¦ with the squarewave signal may not fire at a rate t~hich exceeds 18 I the period o~ the squarewave signal. A sinqles play-only 19 ¦ ground connection 180 which normally shorts out this input ~0 ¦ to the NAND gate 146 is opened for such competitive play.
21 ¦ Referring now more particularly to FIG. llC, some o,f 22¦ the more functional aspects of the control circuit will be 231 briefly discussed. When the microprocessor detects that too 241 many coins have been fed into the coin slot 26, it sends a ;
