[0007]

Embodiments of the present invention will be described below with reference to the drawings. The pachinko machine 1 as a ball game machine shown in FIG.
A frame-shaped front frame 3 is attached to the machine frame 2 so as to be openable and closable, and a game board 5 is provided so as to cover a window 4 opened in the front frame 3 from behind, and a front face of the front frame 3 below the game board 5. A ball supply tray 6 is provided, and a ball storage tray 7 and an operation handle 8 are provided below the ball supply tray 6. Further, the front frame 3 is provided with indicators such as a launch indicator 9, an overflow indicator 10, an adjustment indicator 11, and a hit indicator 12. Each of these displays has a light-emitting device such as a light-emitting diode or a lamp therein, and the light-emitting device is turned on or blinked to fire a hit ball, overflow, adjust the hit ball firing device 22,

FIGS. 2 and 3 show a hit ball launching section 13 provided below the game board 5. The hitting ball firing unit 13 includes a firing rail 1 for guiding a ball from the hitting ball firing position 14 into the game board 5.
A firing speed detector 18 for detecting the speed of a hit ball moving on the firing rail 15 is mounted on a firing speed detector mounting portion 17 provided on a base 16 above the firing rail 15. is there. The firing speed detector mounting part 17 is
It consists of a mounting hole 19 formed in the base 16 and a locking projection 20 protruding from the base 16, and a mounting projection 21 provided on the firing speed detector 18 is inserted into the mounting hole 19, and the locking projection 20 is detected for the firing speed.

This reflection type sensor includes a light emitting unit and a light receiving unit (not shown). The firing rail 15 has a black color that does not easily reflect light.

The method of detecting the firing speed by the firing speed detector 18 will be described below. Normally, light emitted from the light emitting unit toward the firing rail 15 is hardly reflected by the firing rail 15 and is not detected by the light receiving unit. Then, when the pachinko ball passes over the firing rail 15, the pachinko ball is plated so as to easily reflect light, so that the light emitted from the light emitting unit is reflected by the pachinko ball and enters the light receiving unit. The firing speed of the hit ball can be determined from the time when the reflected light is detected by the light receiving unit. That is, the shorter the time for detecting the reflected light, the higher the firing speed, and the longer the time for detecting the reflected light, the lower the firing speed. The firing speed detector 18 is not limited to the one described above, and may be any type as long as it can detect the firing speed of a hit ball. For example, a sensor (proximity sensor, photoelectric type) capable of detecting a ball at two points facing the firing rail 15 Sensors, etc.), and the firing speed may be detected by measuring the time required for the hit ball to pass through the two sensors.

FIG. 16 shows an embodiment of the operation time setting means 74. The operation time setting means 74 is provided with a plurality of units in which a diode D and a resistor R are connected in series, one end of the resistor R is connected to a “+” electrode, the other end of the diode D is grounded, An output is obtained from the contact point of the resistor R and the output is "H" depending on the direction of the connected diode D.
(High) "or" L (low) ". That is, when the cathode of the diode D is connected to the contact side, the output becomes “H”, and conversely, when the anode of the diode D is connected to the contact side, the output becomes “L”.

The setting means of the firing timing timer 69 includes:
In the connection method shown in the figure, five outputs are used, and when the output “H” is “1” and the output “L” is “0”, the output is “1-1-0-1”. −0 ”. The firing timing timer 69 is set based on the 5-bit signal. Although not shown, the setting means of the firing number timer 70, the setting means of the ball feeding solenoid timer 71, and the setting means of the rotary solenoid timer 72 have the same configuration.

FIG. 17 shows a specific method of connecting the resistor R and the diode D in the operation time setting means 74 described above. The resistor R and the diode D are bridged between the contacts provided on the printed circuit board.

FIG. 18 shows another embodiment of the operating time setting means 74, in which two resistors R are provided between the "+" electrode and the ground point, and an output is obtained from the contact point of both resistors R. so,
When the resistance R on the electrode side of “+” is smaller than the resistance R on the ground side, the output becomes “H” (FIG. 18a), and conversely, “+”
When the resistance R on the electrode side is larger than the resistance R on the ground side, the output becomes "L" (FIG. 18b).

FIG. 19 shows still another embodiment of the operating time setting means 74, in which two resistors R are provided between the "+" electrode and the ground point, and an output is obtained from the contact point of both resistors R.
A dip switch DS is provided on the ground side of the contact.
When the dip switch DS is opened and the resistance R on the ground side is not connected, the output becomes “H” (FIG. 19A). Conversely, the dip switch DS is closed, and the resistance R on the “+” electrode side is changed to the ground side. Output is “L” when the resistance is larger than R
(FIG. 19b).

FIG. 20 is a timing chart showing the set time of each timer set by the operation time setting means 74 described above. The operation time t1 of the ball feed solenoid 66 is set by the ball feed solenoid timer 71, the operation time t2 of the rotary solenoid 24 is set by the rotary solenoid timer 72, and the operation interval t3 of the ball feed solenoid 66 is set by the firing timer 70. The interval t4 from when the ball feed solenoid 66 is activated by the firing timing timer 69 to when the rotary solenoid 24 is activated is set.

In the timer setting method shown in the timing chart of FIG. 20A, after the ball feed solenoid 66 is turned on and the ball is supplied to the hit ball firing position 14, the rotary solenoid 24 is turned on after the elapse of the standby time t4 and the ball is hit. Fire. That is, t4 set by the firing timing timer 69 is substantially equal to the total value of t3 set by the firing number timer 70 and t1 set by the ball feeding solenoid timer 71.

The reason why the standby time t4 is set to a relatively long time is that it takes some time for the ball supplied to the hit ball firing position 14 by the ball feed solenoid 66 to be stabilized, and after the ball is stabilized. This is because by launching a hit ball, it is possible to accurately launch the shot by preventing uneven flying or the like.

In the method of setting the timer shown in the timing chart of FIG. 20B, the ball feeding solenoid 66 is turned on to supply the ball to the hit ball firing position 14, and the ball feeding solenoid 6
After a certain waiting time t4 has elapsed since the turn-on of the rotary 6, the rotary solenoid 24 is turned on to fire a hit ball.
Then, when the turning-on operation of the rotary solenoid 24 is completed, the ball feeding solenoid 66 is turned on again to supply the next ball to the hit ball firing position 14. That is, the firing number timer 7
T3 set by 0 is the firing timing timer 69
T4 and rotary solenoid timer 7
It becomes almost equal to the total value of t2 set in 2.

FIG. 21 is a timing chart showing the relationship between the output from the start / stop judging means 73, particularly the touch signal, and the driving of the ball feed solenoid 66 and the rotary solenoid 24. The start signal from the touch detection unit 77 and the start signal from the start switch 75 are input to the start / stop determination unit 73 as described above. When the touch signal is on and the activation signal is on, the ball feeding solenoid 66 and the rotary solenoid 24 are driven. When the touch signal is turned off, the ball feeding solenoid 66 is immediately turned on. Is stopped, the ball feeding solenoid 66 is driven once again after the touch signal is turned off, and then the ball feeding solenoid 66 is stopped. This is because even if the player releases his / her hand from the touch plate 79 for a short time, the shooting operation of the ball is performed smoothly.
That is, even if the player releases the hand from the touch plate 79 for some reason, for example, lighting a cigarette, or the touch output is momentarily turned off due to weak touch sensitivity, the firing of the ball is stopped. By performing a smooth firing without any interruption, the game can be continued without spoiling the interest of the game.

FIG. 22 is a timing chart showing the relationship between the output from the start / stop judging means 73, particularly the start signal, and the driving of the ball feeding solenoid 66 and the rotary solenoid 24. The start / stop determination means 73 drives the ball feed solenoid 66 and the rotary solenoid 24 when the touch signal is on and the start signal is on as described above. The rotary solenoid 24
Is stopped, the rotary solenoid 24 is driven once again after the activation signal is turned off, and then the rotary solenoid 24 is stopped. This is to prevent the ball from remaining at the hit ball firing position 14. That is, if the ball remains at the hitting ball firing position 14, the ball is further supplied to the hitting ball firing position 14 when the start switch 75 is turned on again, so that accurate hitting cannot be performed. This is also a cause of failure of the hit ball launching device 22.

FIG. 23 shows an overflow switch 65,
Ball feed solenoid 66 and rotary solenoid 24
5 is a timing chart showing the relationship with the driving of FIG. The ball is filled in the discharge path of the prize ball, and the overflow switch 65
Is turned on, only the driving of the ball feeding solenoid 66 is stopped without stopping the driving of the rotary solenoid 24. This is to prevent the ball from remaining at the hit ball firing position 14 as described above.

FIG. 24 is a timing chart showing the relationship between the hitting signal and the driving of the ball feed solenoid 66 and the rotary solenoid 24. When a hit signal is transmitted from the management device or the like by discharging a predetermined number of prize balls, supply of power to the control circuit is stopped by the relay 60 connected to the power supply 59, and supply and hitting of the hit ball are performed. The firing operation of is stopped.

FIG. 25 is a timing chart showing a method of adjusting the firing force of a hit ball. The rotary solenoid drive control means 64 outputs a rotary solenoid drive control signal. The rotation amount / firing force conversion means 80 outputs a signal obtained by converting a change in the voltage of the variable resistor according to the rotation amount of the operation handle 8 into a pulse signal. This pulse signal has a constant off time and a different on time. The larger the amount of rotation of the operation handle 8, the longer the on time. That is, when the amount of rotation of the operation handle 8 is small and the firing force is weakened, the number of pulses per unit time increases. When the amount of rotation of the operation handle 8 is large and the firing force is increased, the number of pulses per unit time is increased. Is less.

When the rotary solenoid drive control signal is on, the power adjusting means 68 outputs a signal equivalent to the pulse waveform during that time, and the rotary solenoid 24 outputs the signal from the power adjusting means 68. Drive based on the pulse signal. Therefore, the time during which the rotary solenoid 24 is turned off is shorter when the number of pulses per unit time is small than when the number of pulses per unit time is large. That is, if the off time of the rotary solenoid 24 during the driving of the rotary solenoid 24 is short, the firing force becomes strong,
If the off time of the rotary solenoid 24 is long, the firing force becomes weak.

A method of adjusting the firing force of a hit ball will be described with reference to the flowcharts shown in FIGS. If the adjustment processing of the flight distance range is started and the adjustment flag is not set, and the rising of the drive signal of the rotary solenoid 24 is detected, the handle rotation amount is read. Here, when the comparison rotation amount detection means 82 determines that the handle rotation amount is the comparison rotation amount for performing the adjustment, the adjustment flag is set and the firing speed timer is set.

When the firing speed is calculated by the firing speed calculating means 84, the firing speed is adjusted by the firing speed comparison and judgment means 83 and the conversion ratio setting means 86. On the other hand, when the firing speed is not calculated by the firing speed calculating means 84 and the firing timer times out, the ball absence indicator 91 is lit to indicate that there is no ball, the adjustment flag is reset, and the adjustment process is stopped. If the firing timer does not time out, the adjustment process is immediately stopped.

When it is determined by the comparative rotation amount detecting means 82 that the rotation amount of the handle is not the comparative rotation amount for performing the adjustment, the adjustment display 11 and the ballless display 91 are displayed.
Is turned off to stop the adjustment process.

In the above-described firing force adjustment processing by the firing speed comparison / judgment means 83 and the conversion ratio setting means 86 , after turning off the no-ball indicator 91, the firing speed comparison / judgment means 83 stores it in the reference firing speed storage means 85. The determined reference firing speed and the actually measured firing speed are compared and determined. If the measured firing speed exceeds the upper limit of the reference firing speed, the conversion ratio stored in the conversion ratio storage unit 87 is reduced. Conversely, if the measured firing speed is lower than the lower limit of the reference firing speed, the conversion ratio stored in the conversion ratio storage means 87 is increased. The adjustment indicator 11 flashes to indicate that adjustment is being performed.

On the other hand, if the measured firing speed is within the range of the reference firing speed, the adjustment indicator 11 is turned on to indicate that the adjustment has been completed, the adjustment flag is reset, and the adjustment process ends. . When the operation of hitting the ball is stopped by rotating the operation handle 8 back, the ball absence indicator 91 and the adjustment indicator 11 are turned off, the adjustment flag is reset, and the process is terminated.

In the hitting ball firing force adjusting device described above, the firing force of the hit ball is adjusted by adjusting the power supplied to the rotary solenoid 24 which is the driving source of the firing rod 28, but the firing force is not limited to this. The adjustment may be made by another method, for example, by changing the swing range of the firing rod 28.

In order to adjust the swing range of the firing rod 28, as described above, the upper pivoting position of the firing rod 28 is changed by changing the position of the upper cushioning member 38, and By changing the position, the downward rotation position of the firing rod 28 is changed. To determine whether or not the firing force of the hit ball is within an appropriate range, the hit ball is actually fired, and the positions of the buffer members 38 and 43 are adjusted while looking at the display on the adjustment display 11.

FIG. 28 is a schematic block diagram of a portion of the electric control device 58 used in the second embodiment related to the control of the hit ball firing device 22. This electric control device 58
Has almost the same configuration as the above-described electric control device 58 for adjusting the power supplied to the rotary solenoid 24 to adjust the firing force of the hit ball, and therefore only different portions will be described.

In the electric control device 58 of the first embodiment, the turning amount / firing force converting means 80 is connected to the firing speed comparison / determination means 83 via the conversion ratio setting means 86 and the conversion ratio storage means 87. However, in the case of the second embodiment in which the firing force of the hit ball is adjusted by adjusting the swing range of the firing rod 28, the firing speed comparison determination means 83 and the rotation amount / firing force conversion means 80 communicate with each other. In addition, the intermediate conversion ratio setting means 86 and the conversion ratio storage means 87 are also omitted. This is because the second embodiment manually adjusts the swing range of the firing rod 28 and does not require these means.

The adjustment display control means 89 is in communication with two indicators, a first adjustment indicator 11 and a second adjustment indicator 11, and the first adjustment indicator 11 swings the firing rod 28. The indication that the range should be increased is displayed, and the second adjustment indicator 11 indicates that the swing range of the firing rod 28 should be reduced.

The method of adjusting the firing force of the hit ball in the second embodiment is almost the same as that of the first embodiment. If the first adjustment indicator 11 blinks during the adjustment of the firing force of the hit ball,
The swing range of the firing rod 28 is adjusted to be large, and when the second adjustment indicator 11 blinks, the swing range of the firing rod 28 is adjusted to be small. When the firing speed comparison and determination means 83 determines that the firing force is appropriate, the first adjustment display 11 and the second adjustment display 11 are simultaneously turned on to indicate that the adjustment has been completed.
