The acceleration pattern 1 is a pattern having the smallest acceleration. The acceleration patterns 2 and 3 and 4 increase in order, and the acceleration pattern 5 maximizes the acceleration of the ball launching motor 65.

In FIG. 18, t0 is the start point of one cycle TC, but during t0 to t1, the ball firing motor 6 is
No. 5 does not rotate, and in any of the acceleration patterns 1, 2, 3, 4, and 5, the ball discharge plate 62 stops at the origin and is in a standby state. t1 is the actual rotation start time, and t1 to
It accelerates according to each acceleration pattern at t2, reaches the maximum acceleration at t2, then rapidly decelerates, returns to the origin at t3, and stops, and one cycle TC is completed in the stopped state. Further, at times t2, t21, t22, ...
.. is also constant in TC.

In these acceleration patterns 1 to 5, t2, t21, t22, ...
2 is the lowest point in the casing 61, that is, the release point at which the ball is launched toward the launch path 7. In this embodiment, t2, t21, t22, ...
By changing the time width from t0 to t1 for each acceleration pattern, it is set so that the same time point is obtained in any of the acceleration patterns 1 to 5. Therefore, even if the player operates the handle portion 32 to change the firing intensity, the balls are always fired at regular intervals, and the player can perform the handle operation with a stable feeling.

The selection of the acceleration patterns 1 to 5 is made in the firing intensity adjusting section 321 of the handle section 32. The firing intensity adjusting unit 321 includes a firing intensity adjusting volume having an output voltage range of 0 to 5 V, which is configured by a power supply VDD and a variable resistor, as shown in FIG.
The selection voltage Vin when the player operates the handle portion 32 is converted into a digital value of full scale 0-255 (in the case of decimal display) by the 8-bit A / D converter 606 as the emission intensity data.

The CPU 600 selects an acceleration pattern based on the digital value. Select voltage V
The example of selection of the acceleration patterns 1-5 with respect to in is shown. In this example, when the selection voltage Vin is 3.0V, the digital value is 152. In this case, the CPU 600 is
The acceleration pattern 3 is selected from the 0 acceleration pattern table.

The acceleration pattern data for the ball firing motor 65 is given in the ROM 602 as a data string as shown in FIG. Figure 21 shows acceleration pattern 1
The acceleration pattern data in the address area J at the time of is shown. The CPU 600 reads the acceleration pattern data of the ROM 602 in the order of addresses every 2 mS, and when the read data is “1”, outputs a pulse ON signal for the phase Φ to output each of the ball firing motors 65. The pulse widths of the phases Φ1 to Φ4 are controlled to rotate the ball firing motor 65 in a predetermined acceleration pattern.

Incidentally, the acceleration pattern data is one cycle 6
It is composed of data corresponding to 06 mS. This value is 100 balls per minute on a pachinko machine under administrative guidance.
It is a numerical value derived from the fact that it is authorized to launch up to a ball. Therefore, if the administrative guidance changes, this numerical value will inevitably change.
It can be easily implemented by rewriting the contents of 602.

Further, the ROM 602 stores an origin stop time table for acceleration patterns as shown in FIG. At the origin stop time DT, a command to start rotation is issued to the ball launching motor 65, the ball launching motor 65 starts to rotate, and the ball launching plate 6 is securely driven.
It is the time until 2 moves away from the origin.

At the origin stop time DT, the origin detector 63 is turned on if the ball discharge plate 62 does not rotate to a certain angle even if the ball firing motor 65 starts rotating.
This is provided to prevent the switch from OFF to OFF.
After the origin stop time DT has elapsed, the signal state from the origin detector 63 surely indicates the non-origin. As will be described later, the origin stop time DT is monitored to detect an operation error or the like of the ball discharge disc 62.

Next, detailed contents of the launch ball supply control and the launch control will be described with reference to the flowcharts of FIGS. 23 to 35. First, a flow chart showing the overall control shown in FIGS. 23 and 24 will be described. When the power is turned on, the above C
When the reset of the PU 600 is released, the CPU 600
Executes the program from the start address of the ROM 601.

At this time, an initial completion flag and an initial 1 completion flag each consisting of 2 bytes are set outside the work area of the RAM 603 in advance. R above
Since the data of AM603 is indefinite when the power is turned on, when the logical product of arbitrary 2-byte data is taken, the probability that all 16-bit data is 0 is close to 0 (all bits are 0). The probability is 2 minus the 16th power), which are defined as the initial completion flag and the initial 1 completion flag, and when the logical product of 2-byte data is 0, each flag is defined as being set.

In the first loop, since the initial completion flag is not set due to the above principle, the initial processing routine S2 described later is executed to set the initial completion flag, and the interval timer built into the CPU 600 is set. After starting, an interrupt (INT) is generated every 2 mS (S1, S2).
In this example, the start address of the interrupt routine is
It matches the start address of the ROM 601.

After the initial completion flag is set in S2, the input processing routine (S3) and the launch ball supply processing routine (S4 in FIG. 23, S in FIG. 24) every 2 mS.
4 '), the emission processing routine (S5 in FIG. 23, S5' in FIG. 24) and the output processing routine (S6) are executed in a time division manner, and the next interrupt is waited in an infinite loop. The total processing time for each interrupt is certainly shorter than the interval time of 2 mS. Also,
The result of each processing routine is stored in the work area of the RAM 603 and passed to the next processing routine.

In the initial processing routine of S2, as shown in FIG.
As shown in FIG. 5, first, the state of the initial 1 completion flag is determined in S2-1, and if the flag is clear, S2 is set.
-2 clears the work area (timer, flag, etc.) of the RAM 603, sets the I / O port built in the CPU 600 in S2-3, sets the interval timer to 2 mS in S2-4, and then sets the interval timer. The timer interrupt is enabled (S2-5), the initial 1 completion flag is set in S2-6, and the value of the initial wait timer is set to 100 (200 mS) in S2-7.

When the flag is set in S2-1, steps S2-2 to S2-7 are skipped. Next, in S2-8, the state of the initial wait timer is judged, and if it is not 0, 1 (2 mS) is subtracted from the value of the initial wait timer (S2-9), and the input processing routine (S3) is executed to execute the initial processing routine. To finish.

Further, if the value of the initial wait timer is 0 in S2-8, the initial completion flag is set (S2-10), and the initial processing routine ends. This initial weight timer is provided to wait for the input to be fixed when the power is turned on. Note that this initial processing routine is not executed until the power is turned on again after the power is turned off once.

In the input processing routine of S3, as shown in FIG.
As shown in (1), first, in S3-1, the A / D conversion data (emission intensity data) from the A / D converter 606 is read, and subsequently, the presence or absence of various input signals is determined. That is, in S3-2, it is determined whether or not there is an input from the handle stop detection unit 322, and if there is an input, the handle stop ON timer is incremented and the handle stop OFF timer is cleared (S3-3), and there is no input. For example, the handle stop ON timer is cleared and the handle stop OFF timer is incremented (S3-4).

In S3-5, it is determined whether or not there is an input from the touch detection unit 323. If there is an input, the touch ON timer is incremented and the touch OFF timer is cleared (S3-6). The ON timer is cleared and the touch OFF timer is incremented (S3-7).

At S3-8, the management computer 10 is operated.
Whether or not the completion signal is input is determined from 0. If there is an input, the completion signal ON timer is incremented and the completion signal OFF timer is cleared (S3-9). If there is no input, the completion signal ON timer is cleared. The completion signal OFF timer is incremented (S3-10).

In S3-11, it is determined whether or not there is an input from the origin detector 63. If there is an input, the origin ON timer is incremented and the origin OFF timer is cleared (S3-12). If there is no input, the origin is detected. The ON timer is cleared and the origin OFF timer is incremented (S3-13).

Subsequently, in S3-14, the sphere feeding device 8 or the sphere feeding device 8'is set to the state of the sphere feeding reference point by the reference point detector 83 or the reference point detector 83 '. If it is determined that it is located at the reference point, the supply reference point ON timer is incremented, the supply reference point OFF timer is cleared (S3-15), and it is located at the reference point. If not, the supply reference point ON timer is cleared and the supply reference point OFF timer is incremented (S
3-16).

In S3-17, the sphere detector 84 determines whether or not spheres can be supplied from the upper tray 21 to the sphere supply device 8 or the sphere supply device 8 '(that is, The presence or absence of a ball on the upper tray 21 is detected), and if there is an input, the ball supply ON timer is incremented and the ball supply OFF timer is cleared (S3-
18) If there is no input, the sphere supply ON timer is cleared and the sphere supply OFF timer is incremented (S3-19).

In S3-20, the presence or absence of the operation of the ball discharging switch 22 is detected, and if the operation of the ball discharging switch 22 is detected, the ball discharging switch ON timer is incremented (S3-21) and the input processing routine is ended. Also,
If the operation of the ball discharging switch 22 is not detected, the ball discharging switch ON timer is cleared (S3-22), and the input processing routine ends.

As described above, in the pachinko machine of the present invention, the presence or absence of various inputs is checked by the input processing routine.
It is configured so that it can be surely judged only by checking each timer.

The firing ball supply processing routine of S4 and S4 'is composed of a normal processing routine, an error processing routine, an initial processing routine, and a ball discharging processing routine, as shown in FIGS. The launch ball supply processing routine of S4 and S4 'can be used in any of the disk type ball supplying apparatus 8 and the lifting belt type ball supplying apparatus 8'.

In the launch ball supply processing routine of S4,
The normal processing routine is for performing control for supplying the balls to the ball launching device 6 one by one, and the operating condition is that the ball discharging flag is cleared (S4-1) and the control computer 100 completes the operation. No signal, drop switch 2
2 is not operated (S4-2, S4-3), the supply motor reverse rotation flag and the supply motor forward rotation flag are clear (S4-4, S4-5), and the sphere supply device 8 or the sphere The supply device 8'is in the sphere supply state (S4-
6), with the upper tray 21 having a ball (S4-7),
When there is no supply motor error (S4-8), there is no launch motor error (S4-9), and the value of the launch motor rotation timer is 300 mS (S4-10) (in order to take timing with the above ball launching device 6). ), And set the supply motor rotation timer to 200 mS (S4-11).

The supply motor rotation timer detects an abnormality in the sphere supply motor 85 and the supply reference point detector 83 or the supply reference point detector 83 ', and can be surely synchronized with the firing cycle. If the sphere can be supplied to the sphere launching device 6, the time is not limited.

Then, the supply motor forward rotation flag is set (S4-12), and the sphere supply motor 85 is rotated in the output processing routine of S6 described later. Further, when the supply reference point is reached within the specified time (within the time set in the supply motor rotation timer) after the ball supply motor 85 starts rotating, the supply motor forward rotation flag and the supply motor rotation timer are cleared. Then, the ball supply motor 85 is stopped (S4-33 to S4-44).

The above-mentioned operation is a normal operation,
In S4-33, S4-43, and S4-44, the supply motor rotation timer and the supply reference point ON timer are monitored, and even if the time set by the supply motor rotation timer is exceeded, the ball feeding table 82 or the lifting belt is set. 87
Is continuously stopped at the supply reference point or has not reached the supply reference point, the ball supply motor 85 or the supply reference point detector 83 (or the supply reference point detector 8).
It is determined that at least one of 3 ') is abnormal, and the error processing routine is executed.

It is considered that the cause of the error is that the ball supply motor 85 cannot be rotated in the forward direction due to the locking of the sphere supply motor 85 due to the inclusion of foreign matter or the like.
The ball supply motor 85 is operated for a certain time (20 in this case).
mS) After reverse rotation, normal rotation is continued for a certain time (normal 20
A value obtained by adding 20 mS for the number of reverse rotations to 0 mS) is executed.

That is, as shown in S4-45 to S4-52, the supply motor forward rotation flag is cleared, the supply motor rotation timer is set to 20 mS, the supply reference point OFF flag is cleared, and the supply motor reverse rotation flag is set. Is set, the supply motor error counter is incremented, the number of times the error processing routine is executed by the supply motor error counter is checked, and if it is less than 5, it is determined whether the supply motor rotation timer has counted 20 mS. , 20 mS has elapsed, the supply motor reverse rotation flag is cleared.

Then, S4-8, S4-15, and S4
At -12, the sphere supply motor 85 is normally rotated by a value obtained by adding 20 mS to the number of reverse rotations of 200 mS. Here, in S4-50, if the ball supply motor 85 does not operate normally even if the error processing routine is executed five times, a warning of a supply device error is displayed and the system is stopped (S4-53, S4-54).

The initial processing routine is such that when the power is turned on, if the ball feeding table 82 or the hoisting belt 87 is not at the supply reference point, the ball feeding table 82 or the hoisting button is forcibly forced even if the operating condition is not satisfied. This is a processing routine for rotating the belt 87 to the supply reference point, and the processing content is the same as the normal processing routine. However, 8 above
If it is 2 or the above-mentioned lifting belt 87 is located at the supply reference point, this processing routine is not executed (S
4-6, S4-13, and S4-42).

The ball discharging processing routine is executed when a completion signal is received from the management computer 100 in S4-2 or when the ball discharging switch 22 is operated in S4-3, and the ball is shot at the forced termination such as stopping. When the ball is stopped or the ball discharge switch 22 is operated, the upper tray 2
When the balls on the upper tray 1 are ejected, when the balls remain on the upper tray 21, the operation of ejecting the balls to the lower tray 31 is performed.

Prior to this ball discharging operation, first, the ball discharging plate 62 of the ball discharging device 6 is moved from the launch origin position and the ball discharging flag is set (S4-16 to S4).
4-23). This prevents the ball from entering the ball launching device 6.

Next, the sphere supply motor 85 is rotated at a constant speed in the positive direction until a certain time (for example, the time for the hoisting belt 87 to make one revolution) elapses after the sphere detector 84 stops detecting the sphere. Then, all the balls on the upper tray 21 are discharged to the discharge gutter 86 (S4-24 to S4-3).
2).

Also in the launch ball supply processing routine of S4 ', the normal processing routine performs control for supplying the balls to the ball launching device 6 one by one, and the operation condition is that the discharge flag is cleared. (S4'-1), there is no completion signal from the management computer 100, and the ball discharge switch 22 is not operated (S4'-2, S4'-).
3) When the supply motor reverse rotation flag and the supply motor forward rotation flag are cleared (S4'-4, S4'-5), the ball supply device 8 or the ball supply device 8'is in the ball supply state (S4). ′ -6), with the ball on the upper tray 21 (S4′-7), there is no supply motor error (S4).
4'-8), there is no firing motor error (S4'-
9), the value of the firing motor rotation timer is 300 mS (S
4'-10) (for timing with the ball launching device 6), the supply motor rotation timer is set to 200.
Set mS (S4'-11).

The supply motor rotation timer detects an abnormality of the ball supply motor 85 and the supply reference point detector 83 (or the supply reference point detector 83 '), and is reliable in synchronization with the firing cycle. The above ball launching device 6
There will be no time limit as long as spheres can be supplied.

Then, the supply motor forward rotation flag is set (S4'-12), and the ball supply motor 85 is rotated in the output processing routine of S6 described later. Furthermore, within the specified time (within the time set in the supply motor rotation timer) after the ball supply motor 85 starts rotating.
When the supply reference point is reached, the supply motor forward rotation flag and the supply motor rotation timer are cleared to stop the ball supply motor 85 (S4'-24 to S4'-3).
3).

The above-mentioned operation is a normal operation,
At S4'-24, S4'-34, and S4'-35, the supply motor rotation timer and the supply reference point ON timer are monitored, and the ball feeding table 82 or the above-mentioned feeding table 82 is used even after the time set by the supply motor rotation timer is exceeded. When the feeding belt 87 continues to stop at the supply reference point or does not reach the supply reference point, the ball supply motor 85 or the supply reference point detector 83 (or the supply reference point detector 8).
It is determined that at least one of 3 ') is abnormal, and the error processing routine is executed.

It is considered that the cause of the error is that the sphere supply motor 85 could not be rotated in the forward direction due to the locking of the sphere supply motor 85 due to, for example, the inclusion of foreign matter. (20 mS in some cases) After performing reverse rotation, normal rotation is performed for a certain time (a value obtained by adding 20 mS for the number of times of reverse rotation to normal 200 mS).

That is, S4'-45 through S4'-52
, Clear the supply motor forward rotation flag,
How many times the supply motor rotation timer was set to 20 mS, the supply reference point OFF flag was cleared, the supply motor reverse rotation flag was set, the supply motor error counter was incremented, and the error processing routine was executed by the supply motor error counter If it is less than 5 times, it is determined whether the supply motor rotation timer has counted 20 mS, and when 20 mS has elapsed, the supply motor reverse rotation flag is cleared.

Then, in S4'-8, S4'-15, and S4'-12, the number of reverse rotations to 200 mS is 20 mS.
The sphere supply motor 85 is rotated forward by a value obtained by adding. Here, in S4'-41, if the ball supply motor 85 does not operate normally even if the error processing routine is executed five times, a warning of a supply device error is displayed and the system is stopped (S4'-). 44, S4'-4
5).

In the initial processing routine, when the above is not at the supply reference point when the power is turned on, even if the operating condition is not satisfied, the ball feeding table 82 or the lifting belt 8 is forced.
7 is a processing routine for rotating 7 to the supply reference point, and the processing content is the same flow as the normal processing routine. However,
This processing routine is not executed when the above-mentioned ball feeding table 82 or the above-mentioned lifting belt 87 is located at the supply reference point (S4'-6, S4'-13, and S4 ').
-33).

The ball discharging processing routine is executed when a completion signal is received from the management computer 100 in S4'-2 or when the ball discharging switch 22 is operated in S4'-3, and the ball is discharged at the forced termination such as stopping. When the ball is left on the upper tray 21 when the ball is left on the upper tray 21 when the discharge of the ball is stopped or the ball discharge switch 22 is operated, the operation of discharging the ball to the lower tray 31 is performed. It is what you do.

Prior to this ball discharging operation, first, the supply motor forward rotation flag is cleared and the ball discharging flag is set (S4'-16 to S4'-18).

Next, the sphere supply motor 85 is rotated in the reverse direction at a constant speed until a predetermined time (for example, the time for the sphere 82 to make one revolution) elapses after the sphere detector 84 stops detecting the sphere. For example, all the balls on the upper tray 21 are discharged to the discharge gutter 86 (S4'-19 to S4'-2.
3).

The launch processing routines S5 and S5 'correspond to the launch ball supply processing routines S4 and S4', respectively, and as shown in FIGS. 31 to 34, a normal processing routine, an error handling routine, and an initial processing. It consists of routines. The normal processing routine is 606
The ball launching motor 65 is controlled so that the ball launching device 6 launches a ball for each mS.

The operating condition of the normal processing routine of the firing processing routine S5 is that the discharge flag is cleared and the firing stop switch of the handle portion 32 is not pressed by the player so that the touch detection portion of the handle portion 32 is turned on. When the player is touching, there is no completion signal from the management computer 100, and the value of the firing motor rotation timer for managing the number of firings per minute of the ball launching device 6 is 0 (S5- 1 to S5-8), select the acceleration pattern data table according to the A / D converter conversion data (firing intensity data), and set the head address of the table to the motor data address (S5
-9).

Further, the firing motor rotation timer is set to 606.
mS is set (S5-14), and the firing motor forward rotation flag is set (S5-16). As a result, the ball firing motor 65 starts rotating by the output processing routine (S6) described later.

When the ball discharge plate 62 returns to the launch origin within a specified time after the ball launch motor 65 starts rotating, it is determined to be normal operation, and the launch motor forward rotation flag is cleared to set the above. The ball firing motor 65 is stopped (S5-17 to S5-25).

At this time, if the ball discharge board 62 does not return to the launch origin within the specified time, it is determined to be an abnormal operation (S5-17, S5-26, S5-27), and the error processing routine is executed. To do.

It is considered that the cause of the error is that the ball firing motor 65 could not be rotated in the forward direction due to the inclusion of foreign matter or the like. Therefore, in the error processing routine, the ball firing motor 65 is kept for a certain time (this In this case, 20 mS) is reversely rotated, and then forward rotation is performed for a fixed time (a value obtained by adding 20 mS to the normal number of 606 mS for the number of times of reverse rotation).

That is, as shown in S5-28 to S5-35, the firing motor forward rotation flag is cleared, the firing motor rotation timer is set to 20 mS, the firing origin OFF flag is cleared, and the firing motor reverse rotation flag is set. Set, increment the firing motor error counter, check how many times the firing motor error counter has executed the error processing routine, and if less than 5 times, determine whether the firing motor rotation timer has counted 20 mS, When 20 ms has passed, the firing motor reverse rotation flag is cleared.

Then, S5-13, S5-15 and S5
At -16, the ball firing motor 65 is normally rotated by a value obtained by adding 20 mS to the number of reverse rotations to 606 mS.

Here, in S5-33, if the ball firing motor 65 does not operate normally even if the error processing routine is executed five times, a warning of a launcher error is displayed and the system is stopped (S5). -36, S5-
37).

The initial process routine is a process for forcibly rotating the ball discharge disc 62 to the launch origin even if the operating condition is not satisfied when the ball discharge disc 62 is not at the launch origin when the power is turned on. The processing content is the same as the normal processing. However, this process is not performed when the ball discharge board 62 is located at the launch origin (S5-4,
S5-10, and S5-25).

The operating condition of the normal processing routine of the firing processing routine S5 'is that the player is touching the touch detection portion of the handle portion 32 while the firing stop switch of the handle portion 32 is not pressed by the player. And
There is no completion signal from the management computer 100,
When the value of the firing motor rotation timer for managing the number of firings per minute of the ball launching device 6 is 0 (S5'-1)
Through S5'-7), an acceleration pattern data table corresponding to the A / D converter conversion data (firing intensity data) is selected, and the head address of the table is set to the motor data address (S5'-8).

Further, the firing motor rotation timer is set to 606.
mS is set (S5'-13), and the firing motor forward rotation flag is set (S5'-15). As a result, the ball firing motor 65 starts rotating by the output processing routine (S6) described later.

If the ball discharge board 62 returns to the launch origin within a specified time after the ball launch motor 65 starts rotating, it is determined to be normal operation and the launch motor forward rotation flag is cleared to The ball firing motor 65 is stopped (S5'-16 to S5'-24).

At this time, if the ball discharge board 62 does not return to the launch origin within the specified time, it is judged to be an abnormal operation (S5'-16, S5'-25, S5'-26), and error processing is performed. Run the routine.

It is considered that the cause of the error is that the ball firing motor 65 cannot be rotated in the positive direction due to the locking of the ball firing motor 65 due to, for example, the inclusion of foreign matter. In this case, 20 mS) is reversely rotated, and then forward rotation is performed for a fixed time (a value obtained by adding 20 mS to the normal number of 606 mS for the number of times of reverse rotation).

That is, S5'-27 through S5'-34
Clear the firing motor forward rotation flag as shown in
Set the launch motor rotation timer to 20 mS, clear the launch origin OFF flag, set the launch motor reverse rotation flag, increment the launch motor error counter, and determine how many times the launch motor error counter executed the error handling routine. If it is less than 5 times, it is determined whether the firing motor rotation timer has counted 20 mS. When 20 mS has elapsed, the firing motor reverse rotation flag is cleared.

Then, in S5'-12, S5'-14 and S5'-15, 20m for the number of times of reverse rotation to 606mS.
The ball firing motor 65 is rotated forward by a value obtained by adding S.

Here, in S5'-32, if the ball firing motor 65 does not operate normally even if the error processing routine is executed five times, a warning of a launcher error is displayed and the system is stopped ( S5'-35, S
5'-36).

The initial processing routine is a processing for forcibly rotating the ball discharge board 62 to the discharge origin even if the operating condition is not satisfied when the ball discharge disk 62 is not at the discharge origin when the power is turned on. The processing content is the same as the normal processing. However, this process is not performed when the ball discharge board 62 is located at the launch origin (S5'-
3, S5'-9, and S5'-24).

As shown in FIG. 35, the output processing routine S6 is composed of a control routine related to the ball supply motor 85 and a control routine related to the ball firing motor 65. Among them, S6-1 to S6-6 are flows related to the ball supply motor 85, and S6-7 to S6-
Reference numeral 15 is a flow related to the ball firing motor 65.

S6-1 and S6-2 are control of the supply motor rotation timer. If the value of the supply motor rotation timer is not 0, the value of the supply motor rotation timer is decremented.

Further, S6-3 to S6-6 are output controls to the ball supply motor 85, and when the supply motor forward rotation flag is set, the ball supply motor 85 is rotated forward. , The data is output to the output port of the CPU 600, and when the supply motor reverse rotation flag is set, the data is output to the output port of the CPU 600 so as to rotate the ball supply motor 85 in the reverse direction.

S6-7 and S6-8 are controls of the firing motor rotation timer. If the value of the firing motor rotation timer is not 0, the value of the firing motor rotation timer is decremented.

Further, S6-9 to S6-15 are output control to the ball firing motor 65, and when the firing motor forward rotation flag is set and the value of the firing motor rotation timer is larger than 606 mS, In order to rotate the ball supply motor 85 forward at a fixed speed, the CP
When data is output to the output port of U600 and the value of the firing motor rotation timer is 606 mS or less, the data of the motor data address is read and the data is output to the output port of the CPU600 based on the data.

At this time, if the firing motor reverse rotation flag is set, data is output to the output port of the CPU 600 so as to reversely rotate the ball firing motor 65.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the embodiment shown here, and is not limited to the configuration described in the claims. It can be implemented appropriately. For example, in the embodiment of the present invention, once the discharging switch is operated, the discharging operation is not stopped until all the balls on the upper tray are discharged.
The present invention is not limited to this, and the ball discharging operation may be performed only while the ball discharging switch is operated.
