2. Description of the Related Art Conventionally, in order to adjust the launching force of a hitting ball launched by a hitting ball launching device, the amplitude of the launching rod can be adjusted while actually firing the ball in a pachinko machine manufacturing process or at each amusement store.

The firing speed corresponding to the momentum is stored in the firing speed storage means 88. Further, the speed of the hit ball shot during the game is calculated by the shooting speed calculation means 85 as described above and input to the shooting speed storage means 88. The rotation amount of the operation handle 8 at this time is determined by the rotation amount determination means 82. Then, the actually calculated firing speed and the firing speed corresponding to the determination rotation amount stored in the firing speed storage means 88 are output to the firing speed comparison determination means 84.

FIG. 18 shows an embodiment of the operating time setting means 74. This 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 side is connected to the "+" electrode, the other end of the diode D side is grounded, and the diode D The output is obtained from the contact point of the resistor R and the resistor R.
(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 is
In the connection method shown in FIG. 18, 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. 19 shows a specific method of connecting the resistor R and the diode D in the above-mentioned operating time setting means 74. The resistor R and the diode D are bridged between the contacts provided on the printed board.

FIG. 20 shows another embodiment of the operating time setting means 74. Two resistors R1 and R2 are provided between the "+" electrode and the ground point, and the two resistors R1 and R2 are connected to each other. In order to obtain the output, when the resistance R1 on the "+" electrode side is smaller than the resistance R2 on the ground side, the output becomes "H" (see FIG. 20).
a) On the contrary, when the resistance R1 on the electrode side of "+" is larger than the resistance R2 on the ground side, the output becomes "L" (FIG. 20).
b).

FIG. 21 shows still another embodiment of the operating time setting means 74. Two resistors R1 and R2 are provided between the "+" electrode and the ground point, and output from the contact points of both resistors R1 and R2. And the DIP switch DS on the ground side of the contact
The output is "H" when the dip switch DS is opened and the ground-side resistor R2 is not connected (Fig. 21a), and conversely, the dip switch DS is closed and the "+" electrode side The output becomes "L" when the resistance R1 of R is larger than the resistance R2 on the ground side (FIG. 21b).

FIG. 22 is a timing chart showing the set time of each timer set by the operation time setting means 74 described above. The ball feed solenoid timer 71 sets the operation time t1 of the ball feed solenoid 66, the rotary solenoid timer 72 sets the operation time t2 of the rotary solenoid 24, and the firing number timer 70 sets the operation interval t3 of the ball feed solenoid 66. A firing timing timer 69 sets an interval t4 from the activation of the ball feeding solenoid 66 to the activation of the rotary solenoid 24.

In the timer setting method shown in the timing chart of FIG. 22A, after the ball feed solenoid 66 is turned on to supply the ball to the hitting firing position 14, the rotary solenoid 24 is turned on after the lapse of the waiting time t4 to hit the ball. Fire. That is, t4 set by the firing timing timer 69 is t3 set by the firing number timer 70 and t3 set by the ball feed solenoid timer 71.
It is almost equal to the sum of 1.

As described above, the reason why the waiting time t4 is set to a relatively long time is that it takes some time for the ball supplied to the ball striking position 14 by the ball feeding solenoid 66 to stabilize, and after the ball stabilizes. This is because by firing a ball, it is possible to prevent uneven flying or the like and perform accurate ball firing.

In the timer setting method shown in the timing chart of FIG. 22b, the ball feed solenoid 66 is turned on to supply the ball to the hitting firing position 14, and the ball feed solenoid 6
After a certain waiting time t4 has elapsed since 6 was turned on, the rotary solenoid 24 is turned on to fire a hit ball.
Then, when the 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 hitting 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 set by
It is almost equal to the total value of t2 set in 2.

FIG. 23 is a timing chart showing the relationship between the output from the start / stop determination means 73, particularly the touch signal, and the drive of the ball feed solenoid 66 and the rotary solenoid 24. As described above, the touch signal from the touch detection means 77 and the activation signal from the activation switch 75 are input to the activation stop determination means 73. The ball feed solenoid 66 and the rotary solenoid 24 are driven when the touch signal is turned on and when the activation signal is turned on. However, when the touch signal is turned off, the ball feed solenoid 66 is immediately driven. Is not stopped, but the ball feed solenoid 66 is driven once again after the touch signal is turned off, and then the ball feed solenoid 66 is stopped. This is to allow the ball to be smoothly ejected even if the player releases his / her hand from the touch plate 79 for a short time.
That is, even if the player releases the touch plate 79 for some reason, such as lighting a cigarette, or the touch output is momentarily turned off due to weak touch sensitivity, the ball is stopped from being emitted. By smoothly launching the game, it is possible to continue the game without spoiling the interest of the game.

FIG. 24 is a timing chart showing the relationship between the output from the start / stop determination means 73, particularly the start signal, and the drive of the ball feed solenoid 66 and the rotary solenoid 24. As described above, the start / stop determination means 73 drives the ball feeding solenoid 66 and the rotary solenoid 24 when the touch signal is on and when the start signal is on, but the start signal is off. Rotary solenoid 24
Is not stopped, but the rotary solenoid 24 is driven 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 hitting firing position 14. That is, if the ball remains at the hitting ball launching position 14, the ball is further supplied to the hitting ball launching position 14 when the start switch 75 is turned on again, and the ball cannot be accurately hit. This is also because it may cause a failure of the hitting ball launching device 22.

FIG. 25 shows an overflow switch 65,
Ball feed solenoid 66 and rotary solenoid 24
4 is a timing chart showing the relationship with the driving of the. The discharge path of the prize balls is filled with balls, and the overflow switch 65
When is turned on, the drive of the rotary solenoid 24 is not stopped, but only the drive of the ball feed solenoid 66 is stopped. This is to prevent the ball from remaining at the hitting firing position 14 as described above.

FIG. 26 is a timing chart showing the relationship between the stop signal and the driving of the ball feed solenoid 66 and the rotary solenoid 24. When a stopping signal is transmitted from the management device or the like by discharging a predetermined number of prize balls, the relay 60 connected to the power source 59 stops the supply of power to the control circuit, and supplies and hits the ball. The firing operation of stops.

FIG. 27 is a timing chart showing a method of adjusting the firing force of a hit ball. A rotary solenoid drive control signal is output from the rotary solenoid drive control means 64. Further, the rotation amount / firing force conversion means 80 outputs a signal obtained by converting a change in the voltage of the variable resistor due 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 rotation amount of the operating handle 8, the longer the on time. That is, when the amount of rotation of the operating handle 8 is small and it is desired to weaken the firing force, the number of pulses per unit time is large, and when the amount of rotation of the operating handle 8 is large and it is desired to strengthen the firing force, the number of pulses per unit time. Will be 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 power from the power adjusting means 68. It drives based on a pulse signal. Therefore, the rotary solenoid 24 is turned off for a shorter time when the number of pulses per unit time is smaller than when the number of pulses per unit time is large. That is, when the rotary solenoid 24 is driven, the off time of the rotary solenoid 24 is short, the firing force becomes strong,
If the ON time of the rotary solenoid 24 is long, the firing force becomes weak.

A method of adjusting the firing force of the hit ball will be described with reference to the flowcharts shown in FIGS. 28 and 29 show the adjustment processing of the flight distance range. In the case where the adjustment process of the flight distance range is started and the adjustment flag is not set, when the rising of the drive signal of the rotary solenoid 24 is detected, the handle rotation amount is read. If the comparison rotation amount detection means 83 determines that the handle rotation amount is the comparison rotation amount for adjustment, the adjustment flag is set and the firing speed timer is set.

When the firing speed is calculated by the firing speed calculation means 85, the firing speed comparison determination means 84 and the conversion ratio setting means 91 adjust the firing force. On the other hand, when the firing rate is not calculated by the firing rate calculation means 85 and the firing timer times out, the no-sphere display 96 is lit to indicate that there is no sphere, 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 83 that the handle rotation amount is not the comparison rotation amount for the adjustment, the adjustment indicator 11 and the no-sphere indicator 96.
Turn off and cancel the adjustment process.

In the process of adjusting the firing force by the firing speed comparison / determination means 84 and the conversion ratio setting means 91 described above, after the ballless display 96 is turned off, the firing speed comparison / judgment means 84 stores it in the reference firing speed storage means 90. When the measured firing rate exceeds the upper limit of the reference firing rate, the conversion rate stored in the conversion rate storage unit 92 is reduced. On the contrary, when the measured firing rate is below the lower limit of the reference firing rate, the conversion ratio stored in the conversion ratio storage unit 92 is increased. Then, the adjustment indicator 11 blinks to indicate that the adjustment is in progress.

On the other hand, when the measured firing speed is within the range of the reference firing speed, the adjustment indicator 11 is turned on to display that the adjustment is completed, the adjustment flag is reset, and the adjustment processing is completed. .. Then, when the operation handle 8 is turned back and the firing operation of the hit ball is stopped, the no-ball indicator 96 and the adjustment indicator 11 are turned off, the adjustment flag is reset, and the process ends.

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

In order to adjust the swing range of the launch rod 28, the upper pivoting position of the launch rod 28 is changed by changing the position of the upper cushioning member 38, as described above, and the lower cushioning member 43 is moved. By changing the position, the downward pivoting position of the firing rod 28 is changed. In order to judge whether or not the launching force of the hitting ball is within the proper range, the hitting ball is actually shot and the positions of the buffer members 38 and 43 are adjusted while watching the display of the adjustment indicator 11.

The firing rate storage process will be described with reference to FIG. When the firing rate storage switch 87 is turned on, the firing rate storage flag is set, "1" is assigned to the storage count memory x, and the firing rate storage indicator 94 is turned on.
Then, if the firing speed storage flag is set, the value of the storage count memory x is checked, and if the value of x is less than "20", the x-th operation handle turning amount is output and a hit ball is fired. .. Here, when a hit ball is fired and the firing speed of the hit ball is detected, the firing speed corresponding to the xth memory location is stored, and "1" is added to x. When the firing rate storage flag is set and the value of x becomes "20" or more, the firing rate storage flag is reset, the firing rate storage indicator 94 is turned off, and the process is terminated. That is, the rotation amount and the firing speed corresponding thereto are stored 20 times when the value of x is "1" to "20".

The automatic adjusting process of the firing speed will be described with reference to FIG. When the rising of the drive signal of the rotary solenoid, which is the drive source of the hitting ball launching device, is detected, the automatic adjustment flag is set and the amount of rotation of the operation handle at that time is read. Then, the rotation amount determination means 82 determines which rotation amount the read rotation amount corresponds to among the 20 levels of rotation amounts output by the rotation amount automatic output means 86. When the firing speed of the hit ball is detected when the automatic adjustment flag is set, the firing speed Mx corresponding to each rotation amount stored in the firing speed storage means 88.
(X is an integer from 1 to 20) is compared with the actually detected firing rate, and if Mx is greater than the actual firing rate, the conversion ratio stored in the conversion ratio storage unit 92 is increased. On the other hand, when M (x + 1) is smaller than the actually detected firing speed, the conversion ratio stored in the conversion ratio storage unit 92 is reduced.

[0062]

As described above, according to the present invention, the launching force of a hit ball is detected by the velocity of the ball shot on the launch rail, and the reference launch velocity is compared with the actually measured launch velocity. By doing so, it is determined whether the launch force of the hit ball is proper, and if it is not appropriate, the proper launch force is adjusted by adjusting the amount of power supplied to the rotary solenoid that is the drive source of the launch rod. adjust.

Therefore, even if the power supply voltage supplied to the pachinko machine changes during the game, or the rotary solenoid, which is the drive source of the firing circuit or the ball striking device, changes its characteristics due to heat or the like, the amount of rotation of the operating handle. Since the launching force of the hitting ball is kept constant, it is possible to stably launch the hitting ball. For this reason, inconveniences such as that the launching force of the hit ball is unstable and the hit ball does not reach the place intended by the player is eliminated, and the enjoyment of the game is enhanced.
