The optimum operation time is determined by a predetermined ratio between the non-discharge time as the non-error area and the excessive discharge time (for example, A: B =
4: 6), and the setting and correction are made at the same ratio within these non-error areas according to the non-discharge time and the excessive discharge time obtained from the test operation of the solenoid 59 during the rewrite operation.

Next, the contents of the control will be described with reference to the flowcharts of FIGS. FIG. 13 shows a main routine of the ball discharging process. When the winning ball is detected by the winning ball detector 23, the number of prize balls to be discharged is set, and it is determined whether or not the current discharging is a discharging operation which is continuous with the previous discharging. The number of emissions is corrected if necessary (0.07 to 0.1
1). Then, balls solenoid 59 of the discharge device 15 requests only times intermittently on-- turns off control, the solenoid 25 of the winning ball processing apparatus 17 the discharge process is completed
Is turned on and off once to discharge one winning ball (0.12 to 0.15). When a ball lending request is generated, the number of balls to be loaned is set based on a signal from the control unit 200 of the ball lending apparatus 2, and a discharging process based on the number is performed (0.16 to 0.18).

When the power of the pachinko ball is turned on, the solenoid 59 is used.
And setting of the operation time, the setting instruction switch 85 is turned on, the predetermined time has elapsed, the predetermined number of discharges has been counted,
When at least one condition among the detection of the discharge error is satisfied, the process shifts to the setting process of the operation time of the solenoid 59 (0.01 to 0.06).

FIG. 14 is a subroutine for explaining the discharging process performed in steps 0.12 and 0.18 of FIG. 13. When an ejection request is issued, a set stored value of the operation time of the solenoid 59 is read out, and the discharging is performed based on this. On condition that there is a ready ball, the on / off control of the solenoid 59 is repeatedly performed until the count value counted via the detector 69 reaches the required number (set number) (1.01 to 1.06).

The operation time setting process of the solenoid 59 (performed in steps 0.01 and 0.06 in FIG. 13) is performed as shown in FIG. The gate 71 is opened, and a non-discharge time setting process (a process for setting a maximum discharge impossible time during which the ball is not discharged even when the solenoid 59 is opened and closed);
Individual discharge time setting processing (similarly, processing of setting the minimum excess discharge time that causes two balls to be discharged by one opening / closing operation of the solenoid 59), and rewriting the optimal operation time based on these results. When the operation is completed, the open / close gate 71 is returned to the closed state (2.01 to 2.0
5).

In the non-discharge time setting processing, as shown in FIG. 16, a preset stored value is read out, and on condition that there is a discharge preparation ball, the solenoid 59 is turned on and off based on this, and the detector 69 discharges the discharge ball. Check for (3.
01-3.04). If there is a discharge ball, the on-off control of the solenoid 59 is repeated while reducing the operation time of the solenoid 59, for example, every 1 msec until there is no discharge ball, and the operation time when the discharge ball is not detected is changed to the current non-discharge time. Is set and stored (3.05 to 3.09). If there is no ejected ball, the on / off control of the solenoid 59 is repeated until the ejected ball is detected while extending the operation time in the same manner, and when the ejected ball is detected, the previously set stored value is stored as it is as the current non-ejected time (3). .10 to 3.1
4).

In the two-ejection time setting process, as shown in FIG. 17, a preset stored value is read out, and on the condition that there is an ejection preparation ball, the presence or absence of the ejection ball is confirmed by the detector 69 based on this (see FIG. 17). 4.01 to 4.04). If there are two or more discharge balls, the on / off control of the solenoid 59 is repeated while the operation time of the solenoid 59 is shortened every 1 msec until the ball is switched to one discharge, and switching to one discharge is performed. Is stored as the current two discharge time (4.05 to 4.09).

If there are no two ejected balls, the on / off control of the solenoid 59 is repeated while extending the operating time in the same manner, and the operating time when the two ejected balls are detected is set and stored as the current two ejected balls. (4.10-4.14).

Next, the overall operation will be described. When each of the winning holes of the game board is won, the winning ball is guided to the processing device 17 and once stopped by the locking claw 24a of the stopper mechanism 22 thereof. When a request for discharging a prize ball is generated by turning on the detector 23, the solenoid 59 of the ball discharging device 15 is turned on and off intermittently by the number of times of operation according to the set number, and the sprockets 56a, 56 per one operation time. b
The rotated every predetermined angle, the sprocket 56a, 56b
The pachinko balls are dropped one by one alternately from. Detector 6
When the counted number of ejected balls detected at 9 reaches the set number, the solenoid 59 is kept in the OFF standby state until the next ejection request occurs. When the ball discharging operation is completed, the solenoid 25 of the winning ball processing device 17 is turned on and off once to release one winning ball via the locking claw 24a.

The control unit 200 of the ball rental device 2
When a request to discharge a loaned ball is generated based on a command from the controller, the solenoid 59 of the ball discharging device 15 is turned on and off in the same manner as described above according to the number of requests, and the sprockets 56a, 5
A set number of lending balls are discharged through 6b. By pressing the ball lending button 9 on the front of the pachinko machine 1, the lending balls can be repeatedly discharged within the range of the card balance.

It should be noted that the sprocket 56
The balls that fall sequentially and alternately through a and 56b
Is discharged to the supply tray 6 and the tray 7 on the front of the pachinko machine 1.

In this case, the stopper mechanism 37 of the ball discharging device 15 includes sprockets 56a and 56b for restricting the flow of the pachinko balls in the parallel path, a locking member 58 for preventing the rotation of the sprockets 56a and 56b, and locking. The sprockets 56a and 56b rotate with the weight of a pachinko ball, and do not require a driving force, because the structure includes a solenoid 59 for releasing the member 58 and the like.

As described above, when a pachinko ball discharge request is generated, the solenoid 59 is intermittently turned on and off with the set operation time corresponding to the number of times of operation corresponding to the number of requests, so that the solenoid 59 is controlled in accordance with the number of discharge requests. Compared to the conventional case in which the operation is controlled so as to be kept ON only for the operation time, one operation time of the solenoid 59 can be set to a constant appropriate value irrespective of the number of balls required for discharge, that is, set according to the number of requests. Since there is no need to change the value, it is easy to respond to the pachinko machine 1 including the ball rental device 2. Also, the solenoid 59
Since the discharge is controlled for each ball via, the error is relatively small and the discharge accuracy of the ball can be improved.

By the way, the optimal operation time of the solenoid 59 may have a slight difference due to a variation in the manufacturing of the components of the pachinko machine 1, abrasion of the components over time due to use, heat generation of the drive unit, and the like. The supply voltage may gradually change due to a change in the supply voltage or the like. In this case, when a specific condition is satisfied, the operation time of the solenoid 59 is corrected by executing a predetermined rewrite operation, thereby effectively preventing a discharge error. .

The rewriting operation is performed by the solenoid 59 if necessary.
The maximum non-discharge time during which the solenoid 59 is not discharged even if the solenoid 59 is operated once based on the signal of the detector 69 while shortening or extending the operation time every 1 msec. The minimum two ejection times at which two balls are ejected by the operation of the above are determined. These results, that is, appropriate design values for these in an actual non-error area corresponding to a change in the state of the ball ejection device 15 and the like. Therefore, the configuration of the control system can be simplified as compared with the case where the design value itself is corrected, and a highly accurate correction value (optimum operation time of the solenoid 59) can be obtained.

As the conditions for starting the rewriting operation, in addition to turning on the power of the pachinko machine 1 and turning on the setting instruction switch 85, the elapse of a predetermined time or the detection of a predetermined number of discharge balls and the detection of a discharge error are also added to the conditions. Thorough measures can be taken against emission errors.

During the rewriting operation, the opening / closing gate 71 of the ball drain gutter 70 opens to shut off the downstream side of the discharge gutter 36, so that the falling balls from the sprockets 56a and 56b are collected through the ball drain gutter 70. Will be.
