Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supplies a game ball by operating an electric drive source and shoots a game ball of a pachinko machine that repels the game ball supplied by operating the electric drive source. Regarding the mechanism.

[0002]

2. Description of the Related Art A game ball launching mechanism in a conventional pachinko machine comprises a ball feeding device, a hitting ball launching device, and a drive control means, and is capable of bouncing a ball at a substantially constant speed. This ball feed mechanism uses a mechanism that operates by the weight of the supplied ball when the game ball stored in the ball supply tray is supplied, and the timing of sending the ball to the ball striking device is constant. There is. Further, a ball feeding device for sending a game ball to an hitting ball launching device by an electric drive source has also been developed, and the drive control means is configured so that the electric driving source of such a ball feeding device also maintains a constant operation timing. As a result, the timing of supplying the ball to the hitting ball launching device does not get out of order.

[0003]

However, in the conventional game ball launching mechanism, since the viewpoint is to keep the operation timing constant, the ball sending timing of the ball feeding device and the hitting timing of the hitting ball launching device. Is not configured to be variably set. Therefore, when the model of the pachinko machine is changed and the operating structure of the ball feeding device is changed, the time required to supply the ball to the ball launching device is different, so drive control means suitable for the ball feeding device is required. It is uneconomical to use. In addition, the standby ball immediately after reaching the launch position from the ball feeding device often moves slightly, and when such an unstable standby ball is repelled, the repulsion part of the launching pestle of the ball striking device releases the ball. Since the trajectory of the launch ball is not fixed because it deviates from the core, it causes so-called uneven flight,
It is desirable to set a long time from the arrival of the firing position of the standby ball to the firing by the firing pestle. Therefore, it has been desired to develop a game ball launching mechanism for a pachinko machine that allows stable setting of the driving timing of the ball feeding device and the ball launching device.

[0004]

The present invention has been made in view of the above, and a ball for pachinko game is launched by operating an electric drive source (for example, an electromagnet 12) to a launch position of a launch rail (13). Ball feeding device (1
0) and an electric drive source (eg rotary solenoid)
By activating the ball, the ball standing by at the launch position (14) of the launch rail (13) is repelled to reach the inside of the game section of the game board for the pachinko game (1).
6), a ball feed device drive control means (42) for supplying drive power to the ball feed device (10), and a ball hitting device drive control means (for example, a rotary) for supplying drive power to the ball hitting device (16). Solenoid drive control means 43 and power adjustment means 44), and the above-mentioned ball feeding device drive control means (4
2) and by controlling the drive power supply timing by the hitting ball launcher drive control means (43, 44),
Timing control means (40) for controlling the drive timing of the ball feeding device (10) and the hitting ball launching device (16);
The timing control means (40) is a ball feed device drive control means (42) and a ball launching device drive control means (43,
44), and operation timing setting means (for example, operation time setting means 49) for variably setting the timing for controlling.

[0005]

By variably setting the operation timing setting means, it is possible to change the timing at which the timing control means controls the ball feeding device drive control means and change the setting timing for operating the electric drive source of the ball feeding device. By variably setting the operation timing control means, it is possible to change the timing at which the timing control means controls the hitting ball launching device drive control means and change the setting of the timing for operating the electric drive source of the hitting ball launching device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a pachinko machine 1 equipped with a hitting ball launching device for a pachinko machine according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the pachinko machine 1 comprises a hollow box frame-shaped machine frame 2 provided with a front frame 3 which can be opened and closed at the front opening. Then, a game board (not shown) is arranged so as to close the upper part of the window portion surrounded by the metal frame of the front frame 3 from the rear side, and when a game ball, which is a game medium, is shot into the game portion of this game board. By paying game balls to various prizes or variable prize devices provided on the game board, a pachinko game in which prize balls are obtained can be performed. Further, a glass frame 5 for holding the glass 4 at a predetermined position where the board surface of the game board can be visually recognized is provided so as to be openable and closable to a position where the upper portion of the window portion of the front frame 3 can be closed, and the front panel 6 is further provided below the glass frame 5. Is provided so that it can be opened and closed, and the window portion of the front frame 3 is closed by the glass frame 5 and the front panel 6. When the glass frame 5 or the front panel 6 is in the open state, a metal frame switch (not shown) is turned on so that the state can be detected.

A ball supply tray 7 for storing balls to be supplied to a hitting ball launching mechanism, which will be described later, is provided at an appropriate position on the front surface side of the front panel 6, and a ball receiving tray 8 is provided at an appropriate position immediately below the same. Balls that cannot be stored in the ball supply tray 7 and overflowed are formed on a back mechanism board (not shown) (provided on the back side of the front frame 3 and provided with a prize ball discharge mechanism, a prize ball processing mechanism, etc.). It is guided to the ball tray 8 through the distribution gutter. When the ball cannot be discharged to the ball tray 8 and overflows into the distribution gutter, an overflow switch (not shown) provided at an appropriate position in the distribution gutter is turned on to detect the state. Is done.

The spheres stored in the sphere supply tray 7 are located on the back side of the front panel 6 from the sphere supply port 9 and the sphere feeding device 1
0 (see FIG. 3). The sphere supplied to the sphere feeding device 10 comes into contact with the sphere receiving member 11 in the first state that prevents the sphere from flowing down, and stops. Then, the ball receiving member 11
When the ball receiving member 11 is attracted to the electromagnet 12 by energizing the electromagnet 12 that is an electric drive source disposed at a proper position above the ball, the ball receiving portion 11a of the ball receiving member 11 can receive the ball. Converted to 2 states. Thus, the sphere is received by the sphere receiving portion 11a of the sphere receiving member 11 which has been converted to the second state. After that, when the energization of the electromagnet 12 is stopped, the ball receiving member 11 returns to the first state with the ball received in the ball receiving portion 11a, and the ball guided downward by the ball receiving member 11 is shown in the figure. After passing through the ball passage, the guide rail (not shown) forming a bullet ball path into the game section of the game board reaches the launch position 14 of the launch rail 13. The sphere located behind the sphere received by the sphere receiving member 11 is stopped by the sphere receiving member and waits until the sphere receiving member 11 is converted into the second state again. The electric drive source in the ball feeding device 10 is not limited to the electromagnet 12, and a solenoid, a motor or the like may be used as a drive source.

As described above, the standby ball which has reached the launch position 14 of the launch rail 13 is hit by the hit ball launching device 16 which is operated by the player operating the operating handle 15. This hitting ball launching device 16 has a mounting board 1
The launching punch 20 is fixed to the output shaft 19 of the rotary solenoid 18 fixed to 7. Further, a first punch receiving member 21 and a second punch receiving member 22 for restricting a rotation range of the launching punch 20 are provided on the mounting substrate 17, and the launching punch 20
The handle 20b of the launching pestle 20 in the first state in which the resilient part 21a of the firing pivots backward and is separated from the launch rail 13 and stands by.
Is in contact with the first punch receiving member 21 (indicated by the solid line in FIG. 6), and the resilient part 20a of the launching punch 20 faces the launching position 14 of the launching rail 13 in the second state.
0b contacts the second punch receiving member 22 (shown by the broken line in FIG. 6).

The rotary solenoid 18, which is an electric drive source of the ball-striking device 16, has, for example, four magnetic pole generators (first magnetic pole generator 23a, second magnetic pole generator 23b, third magnetic pole generator 23c, fourth magnetic pole generator). And a suction portion (first suction portion 25a, second suction portion 25b, which is aligned with the magnetic pole generation portions 23a to 23d of the stator 24). A rotor 26 having a third suction portion 25c and a fourth suction portion 25d) formed on the peripheral portion of the output shaft 19, and the rotor 26 does not come into contact with the stator 24. The output shaft 19 is mounted so as to be rotatable in the empty portion. By energizing the magnetic pole generating portions 23a to 23d of the stator 24, a magnetic field is generated from the coils of the first to fourth magnetic pole generating portions 23a to 23d, and the first to fourth attracting portions 24a made of magnetic material are generated. The suction force acts on 24d.

Therefore, the launching punch 20 has the first punch receiving member 2
In the first state in which the first suction unit 25 is in contact with the first suction unit 25,
a is the attraction force of the first magnetic pole generator 23a,
5ba is the attraction force of the second magnetic pole generating portion 23b, the third attraction portion 25c is the attraction force of the third magnetic pole generating portion 23c, and the fourth attraction portion 25d is the attraction force of the fourth magnetic pole generating portion 23d. In order to operate, the rotation startable state (see FIG. 7) is adjusted by adjusting the positional relationship between the first to fourth magnetic pole generating portions 23a to 23d and the first to fourth attracting portions 25a to 25d. .. Therefore, when the stator 24 is energized, the rotor 2
6 surely starts rotation in the direction in which the launching pestle 20 in the first state is converted to the second state.

The rotor 2 started to rotate as described above.
6, the first to fourth attracting portions 25a to 25d rotate further than the aligned state (see FIG. 8) in which the first to fourth magnetic pole generating portions 23a to 23d of the stator 24 face each other, and the launching pestle 20 moves. When it collides with the second punch receiving member 22, it is in an excessively rotated state (see FIG. 9).
(See). In addition, each magnetic pole generation portion 23a of the stator 24
Power to ~ 23d is applied to the rotor 26 as described in detail later.
Since each of the suction portions 25a to 25d of FIG. 1 stops before reaching the alignment state from the rotation startable state, while the rotor 26 reaches the over-rotation state from the alignment state, the rotor 24 is rotated in the reverse direction (the launching punch 20). To return to the first state). Therefore, the firing pestle 20 reaches the second state without the rotation speed being significantly reduced.

Then, the launch pestle 20 that has reached the second state.
Is the firing position 1 of the firing rail 13 by the firing unit 20a.
The ball on standby at 4 is repelled, and the ball again returns to the first state. Here, the handle 20b of the launching pestle 20 is shaped so as to extend only toward the resilient part 20a side with respect to the base end 20c fixed to the output shaft 19, and the first pestle receiving member 21 and the second pestle are provided. In the rotation range regulated by the receiving member 22, it functions as a biasing unit that automatically biases the launching punch 20 to the first state. Therefore, the second punch receiving member 2
The launching pestle 20 that has collided with 2 and is temporarily stopped returns to the first state by itself without applying an external force. In addition,
In order to quickly return the launching pestle 20 to the first state,
The handle 20b may be given an appropriate weight and the second punch receiving member 22 may be formed of a material having a relatively high elastic modulus such as medium soft rubber. Further, the first punch receiving member 21 is formed of a material having a low elastic coefficient and a good cushioning effect, and the launching punch 20 returned to the first state is repelled by the first punch receiving member 21, It should not rotate again to the second state.

Further, when the launching pestle 20 is in the first state, the rotor 26 is ready to start rotation, and when the launching pestle 20 is in the second state, the rotor 26 is in the over-rotation state, so that the launching pestle 20 is in a rotatable state. In order to keep the fixed relation between the output shaft 19 and the output shaft 19 constant, for example, the peripheral portion of the output shaft 19 is notched and the fitting portion 27 is formed.
And a fitting hole 28 having a required shape capable of fitting with the fitting portion 27 is formed in the base end portion 20c of the firing punch 20, and the fitting portion 27 and the fitting hole 28 are fitted together. With the launching punch 20 fitted to the output shaft 19 by means, a nut is screwed into a thread groove formed on the shaft end portion of the output shaft 19, and the launching punch 20
Is fixed to the output shaft 19. By doing so, the stator 24 of the rotary solenoid, the rotor 26, and the launching punch 20 can be assembled in a state in which the positional relationship is kept constant, and the manufacturing work of the ball striking device 16 can be easily performed. In addition, the device itself can be highly reliable. In addition, in this embodiment, since the fitting portion 27 has a symmetrical shape, the firing punch 20
The index portion 29 (punch hole or the like) for specifying the direction in which the is extended is provided. Further, when assembling the stator 24, the rotor 26, the launching punch 20 and the like, a spacer or a sealing material having good slidability is interposed.

On the other hand, in the embodiment shown in the drawings, the second
The pestle receiving member 22 is held by the holder 30. By appropriately adjusting the position of the holder 30 which is slidable in the left-right direction with respect to the mounting substrate 17, the rotatable range of the launching pestle 20 can be finely adjusted. By slightly changing the position where the launching pestle 20 reaches the second state, it is possible to increase or decrease the resilience of the standby ball. Further, as shown in FIGS. 10 and 11, by changing the stator 24 with respect to the rotor 26, the positional relationship between the stator 24 and the rotor 26 of the rotary solenoid 18 can be finely adjusted. Good.
Further, the electric drive source of the hitting ball launching device 16 is not limited to the rotary solenoid 18, and a plunger type linear solenoid or the like may be used as the electric drive source.

Next, the drive control means 31 for supplying driving power to the ball feeding device 10 and the hitting ball launching device 16 will be described with reference to the block diagram of FIG. The drive control means 31 includes the ball feeding device 10 and the hitting ball launching device 16.
Together with this, it constitutes a game ball launching mechanism.

The drive control means 31 outputs a touch signal output from the touch plate 32 when the player touches the operation handle 15 and an activation switch 33 which is turned on when the operation handle 15 is rotated. Only while the start signal is being input, drive output to the ball feeding device 10 and the hitting ball launching device 16 is performed, and the overflow detection output signal from the overflow switch 34 and the opening detection from the metal frame switch 35 described above are performed. When any of the signal and the stop signal from the management device 36 that comprehensively manages each pachinko machine 1 in the amusement store is input, the drive output to the ball feeding device 10 and the ball launch device 16 is stopped. To do.

First, the touch signal output from the touch plate 32 is the touch detection means 3 in the drive control means 31.
7, and the touch detection unit outputs the first startable signal to the start / stop determination unit 39 based on the input of the touch signal. The touch detection unit 37 is provided with a sensitivity adjustment unit 37a so that the detection sensitivity of the touch signal input from the touch plate 32 can be adjusted.

The activation signal output from the activation switch 33 is input to the firing stop means 39, and based on the activation signal being input, the firing stop means 39 outputs the second activation signal to the activation stop determination means 38. Output to. The firing stop means 39 is supposed to be supplied with an overflow detection output signal, an open detection signal, and a stop signal, and while any of the signal outputs is being inputted to the firing stop means 39, a start switch Even if the activation signal is input from 33, the output of the second activation signal is regulated.

As described above, when the first activation enable signal from the touch detection means 37 and the second activation enable signal from the firing stop means are simultaneously input, the activation stop determination means 3
The reference numeral 8 outputs a start enable signal to the timing control means 39 and also outputs a start-up signal to the display control means 41.

Then, the timing control means 40 to which the start enable signal is input outputs a drive command to the ball feeding device drive control means 42 and the rotary solenoid drive control means 43 at a predetermined timing, and the ball feed drive control means 42 outputs. A drive current is supplied to the electromagnet 12 of the ball feeding device 10 at a predetermined timing for a predetermined time, and a drive current is supplied from the rotary solenoid drive control means 43 to the rotary solenoid 18 of the hitting ball launching device 16 via the power adjusting means 44. It is supplied at a timing for a predetermined time.

On the other hand, the display control means to which the start-up signal is input from the start / stop determination means 38 outputs the display to the launch indicator 45 provided at a proper position on the front frame 3, and turns on (or blinks) the launch indicator 45. ) By displaying it, it is shown that the ball launching operation by the hitting ball launching device 16 of the pachinko machine 1 is being performed. Further, the display control means 41
Is input with an overflow detection output signal from the overflow switch 33, an opening detection signal from the metal frame 35, and a stop signal from the management device. The display control means 41 responds to each input signal. , Overflow indicator 46, gold frame open indicator 47, stop indicator 4
8 is displayed and output, and the stop condition when the ball feeding device 10 and the hitting ball launching device 16 of the pachinko machine 1 are stopped is visually displayed.

The pulse waveform supplied from the drive control means 31 to the rotary solenoid 18 of the ball striking device 16 is:
As shown in the timing chart of FIG. 13, it is shorter than when the firing pestle 20 starts the conversion from the first state to the second state and reaches the position where the stator 24 and the rotor 26 of the rotary solenoid 18 are aligned. It is supposed to turn on only for t2 hours. This t2 time is the rotary solenoid 18
Handle 2 that functions as a driving force for the robot and a biasing means for the launching pestle 20
It is set in advance by the operating time setting means 49 according to the weight of 0b or the like.

The operation time setting means 49, which is the operation timing setting means, connects a resistor R and a diode D in series between a power supply terminal and a ground terminal as shown in FIGS. It is equipped with a proper number of data output basic units configured to obtain a signal output from the connection point between the diode D and the diode D. The resistance D and the diode D can be changed by making the connection direction of the diode D different in each data output basic unit. The signal level obtained from the connection point with is changed (the signal level is high when the cathode of the diode D is connected to the resistor D side, and the signal level is low when the cathode of the diode D is connected to the ground terminal side. ), The operation time setting data constructed by the combination of the signal levels obtained from these data output basic units Idotaima 50 (t2 counting a), ball feed timer 51 (t1 counting a), (counting the t3) firing timer number 52, the firing timing timer 53 (t4
Is supplied to each of them.

When the high-level output and the low-level output supplied from these data output basic units to each timer are "1" and "0", for example, the firing timing timer 53 is used.
The data signal of "11010" is supplied to the. Although not shown in FIG. 14, a data signal is similarly supplied to the rotary solenoid timer 50, the ball feed timer 51, and the firing number timer 52, and the time measured by each timer is set based on this data signal. To be done.

Further, the output means of the "1" and "0" signals supplied from the operating time setting means 49 to each timer is not limited to the above-mentioned configuration, and for example, as shown in FIG. 16, a first resistor R1 and a second resistor R1 are provided. R2 is connected in series between the power supply terminal and the ground terminal, and the resistance value of the second resistor R2 on the ground terminal side is set to the first resistance R1.
A high-level signal output is obtained by setting the resistance value of the second resistor R2 lower than that of the first resistor R1, and a low level signal output is obtained by setting the resistance value of the second resistor R2 lower than that of the first resistor R1. The level signal output is obtained (FIG. 16).
(See (b)). Further, as shown in FIG. 17, a DIP switch DS is interposed between the first resistor R1 and the second resistor R2, and the DIP switch D
By setting S to open and close in advance, "1""0"
It may be configured to obtain a signal. In the embodiment shown in FIG. 17, the resistance value of the second resistor R2 is set lower than the resistance value of the first resistor R1, and a signal is output from between the first resistor R1 and the DIP switch DS. However, the resistance value of the second resistor R2 may be set higher than the resistance value of the first resistor R1, and a signal may be output from between the dip switch DS and the second resistor R2.

Since the rotary solenoid timer 50, the ball feed timer 51, the firing number timer 52, and the firing timing timer 53 described above are constituted by a microcomputer together with the timing control means 40 and the like, the operation time setting means 49 provides data. Although the signal is supplied to each timer, the firing timing setting means is not limited to this. For example, a graduation may be provided at preset constant intervals, and the dial may be adjusted to the graduation so that the variability can be set. Further, the variable control switch provided in the drive control means 31 may be directly operated from the outside by a remote controller without directly operating it.

As described above, the rotary solenoid timer 50 and the ball feed timer 5 in which the time count is set based on the data signal supplied from the operation time setting means 49.
1, firing number timer 52 and firing timing timer 53
For example, when a timing command is input from the timing control means 40, a predetermined time (t1 to t4) is clocked, and when each timer times out, a timing end signal is output to the timing control means 40. Then, these measured time t1
The timing control means 40 controls the energization of the electromagnet 12 of the ball feeding device 10 and the rotary solenoid 18 of the hitting ball launching device 16 based on t4.

The timing of energizing the ball feeding device 10 and the hitting ball launching device 16 having the above-described construction will be described with reference to the timing chart of FIG. 18 (a). The ball feeding device drive control means 42 converts the drive power supplied from the device power supply 54 via the power supply circuit 55 into direct current of a predetermined voltage and supplies the drive power for t1 time based on the control command from the timing control means 40. While supplying to the electromagnet 12 of the feeding device 10, the same drive power supply is repeated every t3 time from the start of the drive power supply. Further, the rotary solenoid drive control means 43, based on the control command from the timing control means 40, rotates the rotary solenoid of the hitting ball launching device 16 for t2 hours after the lapse of t4 time from the start of the driving power supply of the ball feeding device drive control means 42. The drive power is supplied to 18, and the same drive power supply is repeated every t3 time from the start of the power supply to the rotary solenoid 18.

The time t4 measured by the firing timing timer 53 is the time t3 measured by the firing number timer 52.
The time is set to be slightly longer than the sum of the time t1 measured by the ball feeding timer 51 and the time t1.
Due to the structure of No. 0, as described above, the sphere is received by the sphere receiving member 11 converted into the second state when the electromagnet 12 of the sphere feeding device 10 is turned on.
Ball receiving member 11 that returns to the first state when 2 is turned off
Is guided downwards by way of a suitable ball passage to reach the launch position 14 of the launch rail 13. Therefore, the electromagnet 12
Since it takes a predetermined time for the ball to reach the firing position 14 after turning on, the rotary solenoid 18 is driven after an appropriate delay time from the driving of the electromagnet 12. In this way, by controlling the timing of energizing the electromagnet 12 and the rotary solenoid 18, the elastic action is performed after a predetermined time period for stabilizing the standby ball that has reached the firing position 14 is reached, and immediately after the end of the elastic action. The standby ball is again supplied to the firing position 14, and a sufficient time can be secured until the next repulsive movement.

The structure of the ball feeding device is not limited to the structure of the above embodiment, and for example, the ball feeding device is configured to supply the standby ball to the firing position 14 every time the ball feeding solenoid is turned on. However, such a ball feeding device 1
The energization timing when 0 is used is as shown in FIG. That is, by setting the addition value of the time t4 measured by the firing timing timer 53 and the time t2 measured by the rotary solenoid timer 50 to be substantially equal to the time t3 measured by the firing number timer 52, the firing position 1
Immediately after firing the standby ball of No. 4, the subsequent standby ball is supplied to the launch position 14, and when a sufficient time necessary for the new standby ball to stabilize at the launch position 14 elapses, the ball is fired again. The device 16 carries out a repulsive action. In the following description of the operation control regarding the energization timing, it is assumed that drive power is supplied to the ball feeding device 10 and the hitting ball launching device 16 at the timing of FIG.

The timing control means 40 for controlling the drive timings of the ball feeding device 10 and the hitting ball launching device 16 is provided by the start / stop determining means 38 to which both the first startable signal and the second startable signal are inputted. Based on the supply of the start enable signal, the ball feeding device drive control means 4
The ON / OFF control of the ball feed solenoid drive command signal to 2 and the rotary solenoid drive command signal to the rotary solenoid drive control means 43 is performed. Therefore, when the touch signal from the touch plate 32 or the activation signal from the activation switch 33 is not input to the drive control means 31, the overflow detection signal from the overflow 34, the metal frame opening signal from the metal frame switch 35, or the management device. Any of the stop signals from the drive control means 3
If it is input to 1, the driving of the ball feeding device 10 and the hitting ball launching device 16 by the drive control means 31 is stopped.

However, the drive control of the ball feeding device 10 and the hitting ball launching device 16 is not limited to the simultaneous input of the touch signal and the launch signal. For example, the first launch enable signal from the touch detection means 37 and the launch stop means 39. The timing control means 40 may perform on / off control of the ball feed solenoid drive command signal and the rotary solenoid drive command signal based on the second startable signal. For example, in the timing chart shown in FIG. 19, the player's hand is mistakenly separated from the touch plate 32 of the operation handle 15 for a short time, or the touch signal is momentarily stopped due to poor touch sensitivity. In case,
Even after the first startable signal is stopped, the ball feed solenoid drive command signal is output only once. By doing so, the supply of the standby ball by the ball feeding device 10 is smoothly performed, and it is possible to prevent the player from unintentionally stopping the ball hitting operation. Further, in the timing chart shown in FIG. 20, when the second startable signal indicating that the ball firing operation is restricted is turned off, the output of the ball feed solenoid drive command signal is promptly stopped. However, neither the ball feeding device 10 nor the ball striking device 16 is operated. It should be noted that whether or not to output the ball feed solenoid drive command signal is determined, for example, when the rotary solenoid drive command signal is inverted to the low level, and when the second startable signal is inverted to the high level. Restart the ball feed solenoid drive command signal output.

As described above, the timing control means 4
Based on the rotary solenoid drive command signal being input from 0, the rotary solenoid drive control means 4
3 supplies the driving power from the power supply circuit 55 to the power adjusting means 44 only for t2 time, finely adjusts the supplied power by the power adjusting means 44, and supplies it to the hitting ball launching device 16. That is, the rotary solenoid drive control means 43
The electric power adjusting means 44 constitutes a hitting ball launching device drive control means for supplying driving power to the hitting ball launching device 16. Incidentally, the voltage adjusting means 44 in the present embodiment.
Is, for example, PWM (Pulse Width Mod)
The duty ratio is made different according to the ration system, and the electric power supplied to the hitting ball launching device 16 is adjusted. In addition, the switching operation for performing the voltage adjustment control of the PWM method is performed by the voltage / frequency converter 56.
It is performed based on the on-time and off-time of the pulse signal supplied (see FIG. 21).

The pulse output of the voltage / frequency converter 56 is, for example, the initial value changing means 57 and the variable adjusting means 5.
It can be adjusted by 8. The variable adjustment means 58 is configured to be operable by, for example, a player by changing the amount of rotation of the operation handle 15, and the power adjustment means is provided at approximately the midpoint of the rotation range of the operation handle 15. 44 outputs the output A (FIG. 21) to the hitting ball launching device 16
The initial value changing means 57 is adjusted so as to be supplied to the. In the case where the output A has a strong launching force of the hit ball, the amount of rotation of the operation handle 15 is reduced to obtain a drive output having a low duty ratio (for example, the output B) and a greater launching force than the output A. By increasing the amount of rotation of the operation handle 15, it is possible to variably adjust the drive output (for example, the output C) having a high duty ratio.

The amount of rotation of the operating handle 15 for adjusting the drive output supplied from the power adjusting means 44 to the hitting ball launching device 16 depends on the rotary driving force of the rotary solenoid 18, the driving time, the load (mainly the launching punch). The relationship between the weight of the firing pestle 20 and the rotation range amount of the operating handle 15 based on the ON time of the rotary solenoid 18 is as shown in the table below. ..

[Table 1]

If the amount of rotation of the operating handle 15 is small, it is difficult to finely adjust the flight distance. Therefore, it is desirable to set the amount of rotation of the operating handle 15 relatively large. ..

As described above, in the game ball launching mechanism of the pachinko machine according to the present invention, the timing control means controls the ball feeding device drive control means by variably setting the operation timing setting means. And the timing for operating the electric drive source of the ball feeding device can be changed and the operation timing control means can be variably set to change the timing at which the timing control means controls the hitting ball launcher drive control means. , The timing for operating the electric drive source of the hitting ball launching device can be changed. Therefore, it is possible to freely change the setting of the number of game balls shot per unit time,
By adjusting the drive time of the electric drive source of the hitting ball launching device, the launching force of the hitting ball can be arbitrarily changed. In addition, by setting the drive timing of both the ball feeding device and the striking device according to the structure of the ball launching device, the time from the ball delivered from the ball feeding device reaching the firing position to the firing by the launching pestle is increased. Since it is possible to set and the standby ball that has reached the launch position can be bulleted in a stable state, it is possible to provide a game ball launching mechanism of a pachinko machine that allows stable operation.
