On the other hand, when there are no more or less balls in the storage tank 811, the detection piece 412
Is returned by the force of the return spring in a direction in which the sensor 413 is removed from the sensor 413, and the sensor 413 is turned on (ON), thereby detecting the absence of a ball. When this ball absence state is detected, a detection signal is sent to a management device (not shown) installed in a pachinko game arcade or the like, and balls are supplied to the storage tank 811 in accordance with a command from the management device.

Due to the rotation of the worm 431, the ball on the upstream side of the guide gutter 812 is broken and the ball clogging is released, and when the ball reaches the detecting piece 422, the weight of the ball causes the sensor 42 of the ball clogging detector 420 to detect the ball.
When 3 is turned off (OFF), the ball presence state is detected again. This detection signal is sent to the ball discharge control device 600, and the motor 432 returns to a stopped state according to a command from the ball discharge control device 600.

Is connected, and the emission number signal processing unit, ball clogging signal processing unit, initial setting signal processing unit, and illegal signal processing of other control units (government control device, ball rental control device, management device, etc.) of the gaming machine Units are connected to these processing units,
A discharge number signal, a ball clogging signal, an initial setting signal, and an illegal signal are output, respectively. While receiving these signals, the number-of-emissions signal processing unit, the clogging signal processing unit, the initialization signal processing unit, and the unauthorized signal processing unit turn on various lamps or generate sound effects from speakers (not shown). It is made to let. The microcomputer 1000, the input filter 1020, and the driver 1030 are supplied with a drive voltage from a power supply unit 1040.

This microcomputer 1000 is based on a winning ball signal from the accessory control device 700, a signal indicating a prize mode (winning data), a ball lending signal from the ball lending machine 20, or the like in accordance with a control program described later. The number of balls to be ejected is calculated, and the step motor 253 is rotated by an angle corresponding to the calculated value. Further, the microcomputer is equipped with a count sensor I, II (263A, 263B)
Based on the detection signals from the ball sensors I and II (262A, 262B) and the ball storage state in the ball discharge device 200 (whether or not ball clogging occurs in the ball discharge device, replenishment of the ball) Is completed), and it is determined whether or not to start discharging the ball based on the result, and then the ball is discharged.

When the rotation of the stepping motor 253 is controlled based on the purchase payout signal or the data signal including the number of winnings from the accessory control device 700 to discharge the ball, the number of discharged balls is calculated. Is the step motor 2
The number of balls detected according to the rotation angle of the stepping motor is detected by monitoring the rotation angle of 53, and whether or not the desired number of balls according to the detected rotation angle of the step motor is actually discharged is determined by the count sensors I and II.
The microcomputer 1000 determines based on the detection signal of (263A, 263B).
That is, the number of discharged balls is detected indirectly by monitoring the rotation of the step motor and directly by monitoring the number of actually discharged balls.

More specifically, the microcomputer 1
000, once a series of ball discharging operations (the discharging operation of the number of balls to be discharged set at the beginning of the discharging operation) is started once, one rotation operation of the worm (180 degrees) is performed during the discharging operation. For each rotation), it is determined whether or not a ball is present at the tip 200D of the ball discharge device based on signals from the count sensors I and II. (In this embodiment, one ball is discharged per one rotation operation), and the one rotation operation is performed (1).
80 degree idle rotation). Then, the stored number (the number of balls that were not ejected) is added to the number of balls that should have been ejected by the current series of ejection operations, and a series of ejection operations is performed based on the added value. (Correction of the rotation angle of the step motor). That is, idle rotation is performed until the tip portion 200D is replenished with balls, and the number of balls corresponding to the number of idle rotations is discharged, and the ball discharge control operation of the number of balls to be discharged set at the beginning of the discharge operation is performed. At the end of, it is done following this.

Before executing the ball discharge control, a ball presence sensor is required.
If both the count sensors I and II detect the absence of a ball when the presence of a ball is detected by I and II (262A and 262B), it is determined that the ball is clogged in the ball discharge device 200. And the ballast solenoid 280 is turned on (O
N). The ball is broken in the ball channels 259a and 259b of the ball discharging device 200 by being turned off. Further, at this time, the reverse rotation / forward rotation operation of the step motor is repeatedly performed. And then count sensors I and II
When the ball presence state is detected by one of (263A, 263B), these ball breaking controls are completed.

When there is an overflow signal from the overflow switch 818, the overflow lamp 14 is turned on. When activated, the ball breaking operation in the guide gutter 812 is performed.

FIG. 18 shows the microcomputer 1
000 shows the procedure of the main control process of the ball discharge performed by the 000. When the main control process is started, first, in step S2, it is determined whether or not the current loop is a loop immediately after the power is turned on. Only for “Yes”, the initial setting (for example, the process of setting task 1) is performed in step S4, the present loop is ended, and the process proceeds to the next loop.
On the other hand, otherwise, the process proceeds to step S6, where a task control process for determining which of the tasks 1 to 7 is to be executed in the current loop is performed. That is, in the task control process, the communication process (task 1) in step S10 is performed according to which of “task 1 to task 7” set by each control program described later is set.
Is set), the prize ball discharging process in step S12 (when task 2 is set), and step S12.
14, safe ball processing (when task 3 is set), ball clogging processing in step S16 (when task 4 is set), ball emptying processing in step S18 (when task 5 is set), Step motor positioning processing in step S20 (when task 6 is set), and purchase payout processing in step S22 (task 7
(When is set)). Based on this processing result, after step S6, any one of the task processes of steps S10 to S22 is actually performed, and when those processes are completed, the process proceeds to the next loop and the process is performed again from step S2. It has become.

FIG. 19 shows the microcomputer 1
000 shows the control processing procedure of the interrupt processing performed by the 000. This interrupt processing is performed based on the interrupt signal during the main processing (FIG. 18). When this processing is started, steps S30, S32, S34, S3
6, ie, the input processing to the input filter 1020 (FIG. 17), the output processing from the driver 1030, the timer processing, and the monitoring processing are performed. After the interruption processing is completed, the processing returns to the main processing again. In the above input processing, when the input signal from the ball-pulling sensor, which is input during execution of the ball-pulling operation, becomes high level, the microcomputer 1
000 sets task 5 in the above-described task control processing (step S6 in FIG. 18) based on the high-level signal from the ball removal sensor.

FIG. 20 shows the procedure of the monitoring process (subroutine process) performed in step S36 of the interrupt process (FIG. 19). This monitoring process is a process for detecting the storage state of the spheres in the sphere channels 259a and 259b of the sphere discharge device 200 and the discharge control unit 250, and for storing that fact. When the balls are stored at the lowermost end 252 (FIG. 5) of the worm of the ball discharge device 200 and the balls are supplied to the upstream side of the control unit 250 (in a normal state), the balls are completely contained in the ball discharge device 200. There is no ball, a ball is present at the tip 200D of the ball discharge device 200, but no ball is supplied on the upstream side of the control unit 250. Although there is a supplied ball on the upstream side of the discharge control unit 250, And a state in which no ball exists at the tip portion 200D of the ball discharge device. This monitoring process is performed by the ball discharging device 200
Is a process for judging which of the above conditions is present. When this process is started, first, step S
At 40, it is determined whether or not both of the ball presence sensors I (262A) and II (262B) have detected a ball presence state, that is, whether or not a ball is being supplied upstream of the control unit 250 of the ball discharge device 200. Is done.

If the result of this determination is "Yes", it is further determined in step S42 whether one of the count sensors I and II has detected a ball, while if "No", the flow proceeds to step S44. Similarly, it is determined whether one of the count sensors I and II detects a sphere. When the determination results of the steps S40 and S42 are both "Yes", the ball discharging device 200
Is determined to be in the above state (in a normal state), the process proceeds to step S46, the flag A is set, the other flags B and C are cleared, and the present routine ends. When the flag A is set as described above, a substantial prize ball discharging operation (the operation after step S84 in FIG. 22) is immediately started when the prize ball discharging process (task 2) on the main routine described later is executed. Become like

On the other hand, step S40 and step S40
If both of the determination results of No. 44 are “No”, it is determined that the ball discharging device 200 is in the above state, and step S48 is performed.
It is determined whether communication processing has been performed on the main routine immediately before the start of the interrupt processing (whether or not the task 1 has been set). The result of this determination is “Yes”
In this case (when the main routine is in the process of the task 1 (communication processing)), the flag C is set, the other flags A and B are cleared (step S50), and this routine ends. By setting the flag C in this manner, the later-described initial positioning process (task 6) is preferentially executed on the main routine side (performed in the later-described communication process). If the result of the determination in step S48 is negative "No", this routine ends without changing the flag values (flag A, flag B, and flag C) set at that time.

The result of the determination in step S40 is "No"
When the result of the determination in step S44 is "Yes", it is determined that the state of the stored ball in the ball discharging device 200 is as described above, and the process proceeds to step S52, where all the flags (flag A, flag B, The flag C) is cleared, and this routine ends. That is, the state of (1) is a case where all the balls in the ball discharging device 200 have been discharged as a result of the normal discharging operation by the ball discharging device. Therefore, in this state, replenishment is simply not performed. No abnormality such as clogging has occurred, and no special flag is set. still,
Since the flag A is cleared, the ball discharge operation in the prize ball discharge device (FIG. 22) described later is temporarily performed (the supply of the prize ball to the ball discharge device is completed and the input from the ball presence sensors I and II is performed). (Until the signal goes high).

On the other hand, when the result of the determination in step S40 is "Yes" and the result of the determination in step S42 is "No", that is, the ball exists at the mounting position of the ball presence sensors I and II (supply is being performed). However, if there is no ball at the tip 200D of the ball discharging device 200 (state), the flag B
Is set, other flags (flag B, flag C) are cleared (step S54), and this routine ends. When the flag B is set in this manner, when the prize ball discharge control processing (task 2) is being executed on the main routine side, the processing on the main routine side temporarily changes from the prize ball discharge control processing to the ball collapse processing (task 2). Moving to task 4), the clogged ball condition is eliminated.

Next, the communication processing (task 1) performed in step S10 of the main routine (FIG. 18) will be described with reference to FIG.
1 will be described. This communication processing is based on the data signals and the prize modes (for example, “big hit game state” and “normal game state”) of the prescribed number of discharges (for example, 7 discharges and 15 discharges) from the accessory control device 700 and the ball rental machine 20. Another)
This is a process of reading a data signal or the like indicating the above.

The communication process includes a loop following the initialization of the main routine (step S4 in FIG. 18), a step motor positioning process (task 6), a ball removal process (task 5), and a safe ball process (task 5). This is executed in the next loop in which task 3) has been completed (task 1 is set at this time), and specifically, an accessory data signal (indicating prize mode data) sent from the accessory controller 700. ), And the number of purchase / payout data sent from the ball lending machine 20. The discharge is indicated by the accessory data signal (prize ball signal, prize mode signal) from the accessory controller. The number of balls to be converted is converted into the number of rotations of the step motor, and the data is stored. When the prize balls are not discharged, the purchase discharge processing (task 7) is executed in the next and subsequent loops on condition that the purchase payout signal is received.

When the present routine is started, first, in step S60, "7 discharge processing" from the accessory control device 700.
Alternatively, it is determined whether or not a data signal indicating “15 ejection processing” or the like (the number of balls to be ejected is determined based on these signals) is sent from the accessory control device 700 side.
When the determination result of step S60 is "No", that is, when new prize ball discharge data is not sent from the accessory control device 700, the process proceeds to step S62, and the 180-degree rotation of the step motor is set to one unit. It is determined whether or not the number N of times of rotation is a value other than “0”.

By the way, the prize ball discharge control (task 2) in this embodiment is, as described later, once the control is started, until all the balls to be discharged are discharged unless an abnormality occurs. It is to be continued. Therefore, during the normal operation (normal operation) of the ball discharging device 200, the number of rotations N is "0" at the start of the communication process. When the ball is clogged, the ejection process is temporarily interrupted, and the value becomes other than “0” only when the present communication process (task 1) is executed. Therefore, the determination result of step S62 is "Ye
In the case of s ", the process proceeds to step S78 so that task 2 is set, task 1 is cleared, and the present routine is ended so that the ball discharge process once interrupted in the next loop is restarted.

On the other hand, if the decision result in the step S62 is "No", that is, if there is no prize ball to be ejected at this time (N = 0), the process proceeds to a step S64 to determine whether or not the flag C is set. It is determined whether or not it is. When the determination result is “Yes”, that is, as a result of executing the above-described monitoring process, no sphere is stored in the sphere discharging device 200, and the communication process (task 1) has already been performed at that time. If it has been started, task 6 is set in step S79 (task 1 is cleared), and this routine ends. Thus, in the next loop, the initial positioning process (FIG. 26) of the step motor for converting the ball discharge device 200 to a state in which the ball can be discharged (for example, the state shown in FIG. 6) is started.

If the result of the determination in step S64 is "N
o ", that is, when the ball discharge device 200 is not in the above-described state, the process proceeds to step S66, and it is determined whether or not a purchase payout signal is input from the ball rental machine 20. The result of this determination is" Yes " Sometimes, the task 7 is executed in step S68 so that the purchase payout process (step S22 in FIG. 18) based on the purchase payout signal is performed in the next loop.
Is set, task 1 is cleared, and this routine ends. On the other hand, if the purchase payout signal has not been input, step S68 is skipped, and the routine ends.

On the other hand, at the start of the communication process, the prize ball data signal (the signal is “seven discharges”,
When “15 ejection”, “big hit game state”, or “normal game state” is input (the determination result of step S60 is “Yes”), the microcomputer 1000 outputs the signal. The represented value is read a plurality of times (n times) as prize ball data (step S70). Next, it is determined whether or not all the data values read a plurality of times (n times) match (step S72). If the determination result is “No”, it is determined that the award ball data has not been correctly read. Then, the award ball data is read again in step S70. On the other hand, when the determination result of step S72 is "Yes", the read winning ball data is converted into the number N of rotations of the step motor, and the value is stored (step S74). By the way, step motor 2
In this embodiment, 53 is 1 for every 180 degree rotation as described above.
Since each ball is ejected, the motor is rotated by 180 degrees for each piece of prize ball data, and the number of rotations N is determined as one unit.

When the number of rotations N is calculated and stored in step S74 based on the award ball data, it is further determined in step S76 whether or not the flag C is set.
When the determination result is “Yes”, that is, when the ball discharging device 2
When 00 is in the above-described state (the state where the ball is not present at the tip end portion 200D of the ball discharge device and the ball is not supplied), the step motor initial positioning process (FIG. 26) is performed at the next execution of the main routine. Therefore, the process proceeds to step S79 described above. On the other hand, when the determination result is “No” (when the state is “,”), the process proceeds to step S78, where task 2 is set (task 1 is cleared), this routine is terminated, and the ball discharge processing is performed in the next loop. (FIG. 22)
Is done.

Next, the ball discharging process executed when the task 2 is set will be described with reference to the flowchart shown in FIG. This ball discharging process is performed when a ball is clogged during the ball discharging process when it is determined that there is prize ball data by the communication process (task 1) or after a predetermined number of ball collapses (balls described later). This is a process started when the breaking process (see FIG. 24) is performed (task 2 is set at this time).

Once the discharge process is started, a predetermined number (the number of balls to be discharged by execution of the routine; the number of balls is determined based on the award ball data read at the start of the routine) This routine is continued until the ejection of the ball is completed. Then, in this series of discharging operations, the worm 251 of the ball discharging device 200 is set at the predetermined angle (1
80 degrees) Each time it rotates, it is addressed to a certain number (in this embodiment, it is addressed to one)
Ball ejection takes place. When the ball is actually ejected, as described in detail later, immediately before the start of the worm rotation operation, whether or not the ball exists at the tip 200D based on signals from the count sensors I and II. It is determined whether or not it is. When neither of the count sensors I and II detects a sphere, the worm idles until the count sensors I and II detect a sphere.

When a predetermined number of prize balls are discharged, the prize ball discharged first and the prize ball discharged last are discharged at a low speed. Thus the first one
The purpose of discharging the pieces at a low speed is to prevent the motor from stepping out, to prevent the stepping motor from rotating at a high speed, and to discharge the first piece reliably. In addition, the reason why the last one of the ejected prize balls is ejected at a low speed is that when the step motor that has been rotating at a high speed is suddenly stopped, the stop position is changed to a desired position (the next position). (The position where the ball is locked at the tip 200D). In this ball discharge processing, the discharge speed of the first one prize ball is further increased in two steps according to whether or not the discharge of the prize ball is the first prize ball discharge after the ball clogging processing. To discharge it.
In addition, regarding the prize ball discharge other than the prize ball discharged at the beginning and the end, further according to whether or not the "big hit game state",
Two levels of ejection speed are selected.

When this routine is started, first, it is determined in a step S80 whether or not the flag A is set. The determination result is “No”, that is, the ball discharging device 200
However, when the above state (1) is not satisfied (other than the normal state), the process further proceeds to step S82 to determine whether or not the flag B is set. When the result of this determination is "Yes", it is determined that the ball discharge device 200 is in the state (ball clogged state), and the process skips to step S148, sets a re-discharge flag described later, and stops the step motor. ,
In the next step S150, task 4 is set to execute the ball breaking process in the next loop, task 2 is cleared, and this routine ends.

On the other hand, if the decision result in the step S82 is "No", the ball discharging apparatus 200 judges that the above state or the state is satisfied, and returns to the step S80 again, and returns to one of the steps S80 and S82. Steps S80 and S82 are repeatedly executed until the result of the determination turns to "Yes". During this time, if the ball is replenished into the ball discharging device 200, the ball presence sensors I and II detect this, and the flag B is set at the time of executing the above-described interrupt processing. The determination result in S82 changes to "Yes", and the flow advances to step S148. As described above, when the ball discharge device 200 is in the state at the start of the present routine, first, the ball breaking process (FIG. 24)
Is performed, and thereafter, the present process is executed.

The state of the ball discharge device 200 (normal state)
And the result of the determination in step S80 is “Yes”
In step S84, it is determined based on the data signal from the accessory control device 700 whether or not the discharge of the ball is for discharging the prize ball in the big hit game state. When the determination result is “Yes”, high-speed data (motor speed) is used as normal discharge speed control data of the step motor in order to increase the discharge speed (normal discharge speed) of prize balls other than the first prize ball and the last prize ball. Data 1) is set (step S86). On the other hand, when the determination result is "No", that is, when the discharging control of the prize ball in the normal game state other than the "big hit" is performed, the low speed data (motor Speed data 2) is set (step S8)
8) Go to the next step S90. In this way, by increasing the discharge speed of the prize balls in the jackpot game state where many prize balls are discharged and discharging the prize balls at a low speed in the normal game state, the interest of the game is enhanced. In particular, after a predetermined number of prize balls have been discharged for one safe ball (winning ball),
In a gaming machine of a type in which the safe ball is released from the back mechanism panel, the processing speed of the prize ball discharge in the jackpot game state in which a large number of safe balls (prize balls) are generated is increased. Many will not remain in the mechanism panel.

In the next step S90, the prize ball lamp is turned on (ON) in order to notify the players that the prize ball discharge processing is being executed, and then in step S92, the prize ball is re-discharged. It is determined whether the flag is set. The re-discharge flag is set in the above-described step S148 performed when the ball discharge device is in the state of 〜, and when the first prize ball is discharged after the ball clogging process is completed (described later). In step S99). Therefore, when the determination result is “Yes”, the current loop determines that the prize ball is to be discharged immediately after the ball clogging process described later is completed due to the occurrence of the ball clogging or the ball shortage, and in step S94. The low speed ejection speed of the stepping motor for ejecting the first one is further reduced (motor delay speed data 1 is set) to ensure that the first prize ball is ejected. On the other hand, if the result of the determination is "No", "motor delay data 2", which is a relatively high low speed ejection speed, is set, the step motor is rotated, and the first prize ball is ejected.

In the next step S98, the count sensor
It is determined whether the input signal from either I or II has fallen. As described above, the count sensors I and I
I outputs a high-level signal when a sphere exists in the detection unit (the tip part 200D of the sphere discharge device). Therefore, in this loop, the count sensor I or II
When the input signal from the controller has fallen, it is determined that one ball has been discharged from the ball discharging device 200, and if the re-discharge flag is set at this time, it is cleared (step S99). Next, in step S100, it is determined whether or not one rotation of the step motor has been completed (whether or not it has rotated 180 degrees), and the determination result is “Yes”.
After that, the process proceeds to step S106 and subsequent steps.

On the other hand, if the decision result in the step S98 is "No", that is, the above-mentioned step S94 or step S9
If the ball has not yet been ejected even by the rotation of the step motor in step 6, it is determined in step S102 whether or not one rotation (180 degree rotation) of the step motor has been completed. When the result is “No”, the 180 degree rotation of the step motor has not yet been completed, so in the next step S104, the step motor is set to “motor It is determined based on which of the "delay speed data 1" and the "motor delay speed data 2". When the determination result is “No”, that is, when the step motor has been rotated based on “motor delay speed data 2”, the process proceeds to step S96, and the rotation proceeds with the “motor delay speed data 2”. Is continued and “Ye
In the case of s ", the process proceeds to step S94, and the step motor is continuously rotated at" motor delay speed data 1 ".

Thereafter, during normal operation until the rotation of 180 degrees is completed, the prize ball is ejected and step S
Since the determination result of step 98 turns to “Yes”, step S
The processing after 99 is performed. On the other hand, step S10
If the determination result of No. 2 is “Yes”, that is, if the ball is not discharged despite the completion of the 180-degree rotation, the ball discharging device 200 is determined to be in the above-described state, and Proceeding to step S148, the re-discharge flag is set (and the motor is stopped), and task 4 is set (task 2 is cleared) in step S150. Thereby, control (ball plugging processing) according to the state is started in the next loop.

As described above, a series of processes from the start of this routine until the determination result of step S100 becomes "Yes" discharge one prize ball after the start of the routine (this prize ball discharge is The above two low-speed ejection speeds, that is, either the “motor delay speed data 1” or the “motor delay speed data 2” are completed.

In the processing of step S106 and subsequent steps performed when the discharge of the first piece is completed, first, in step S1
In step 06 and step S108, whether or not the number of prize balls to be discharged (corresponding to the number N of rotations of the step motor in the current loop) stored at the start of this routine is "1" and "2". Is determined individually. When the number of balls to be ejected at the start of the current loop is “1” (for example, when the number of ejected prize balls is one), (Step S10
The determination result of No. 6 is “Yes”. Since one discharge has already been completed at this time by the execution of steps S80 to S100 in the current loop, the process proceeds to step S142.
The step motor is stopped, and the prize ball lamp turned on in step S90 is turned off (OFF).
Proceeding to 144, task 3 is set (task 2 is cleared) in the next loop so that safe ball processing (task 3) for releasing the safe ball corresponding to the current prize ball discharge is performed, and task 2 is cleared. End the routine.

On the other hand, when the result of the determination in step S108 is "Yes" (when the number of prize balls to be discharged at the start of this routine is "2"), another prize ball (finally, Step S to discharge the prize ball to be discharged).
The processing after 132 is executed. As described above, in the present routine, the stepping motor is reliably positioned when the ejection is completed by setting the ejection speed of the last prize ball ejected in the routine to be slower than the ejection speed of the other prize balls. Like that. Therefore, when the number of prize balls to be discharged at the start of this routine (corresponding to the number of rotations N stored at the start of this routine) is "2", the discharge of the second prize ball is performed at a low speed by the following steps. It is performed at the speed (rotation of the motor based on “motor delay speed data 2”).

First, in step S132, whether or not a ball to be ejected is present at the tip 200D of the ball ejecting device 200 is determined according to whether or not the count sensor I or II detects a ball. When the result of this determination is “No”, that is, when there is no ball at the tip 200D,
The number of rotations N is increased by "1" (step S11).
2) After that, the step motor is idled (rotated 180 degrees) for the increased amount (step S114), and the process proceeds to step S122.

If the result of the determination in step S132 is "Ye
s "(when a ball is present at the distal end portion 200D and in a dischargeable state), the process proceeds to step S134.
The step motor is rotated based on the “motor delay speed data 2”. In the next step S136, it is determined whether or not a prize ball has been ejected by this rotation (count sensor I
Or if the input signal from II has fallen), and if the input signal has been discharged ("Yes"), step S1 is executed.
At 38, it is determined whether or not the step motor has rotated 180 degrees. After the determination turns to "Yes", steps S142 and S144 are executed, and the routine ends. On the other hand, if the result of the determination in step S136 is "N
If o "(discharge has not been performed yet), it is further determined in step S140 whether or not the step motor has rotated 180 degrees. If not, the process returns to steps S134 and S136 again. If the process is continued and the discharge is not performed despite the rotation of 180 degrees (when “Yes” in step S140), it is determined that the ball is clogged, and the process proceeds to step S146.
To update the data of the number of rotations N (calculate and store the number of balls to be discharged at this time based on the rotation angle of the already rotated motor, etc.), and re-discharge in step S148 A flag is set (the flag is a flag for storing that the routine was interrupted before the discharge of the number of balls to be discharged is still completed), and the rotation of the step motor is stopped. Then, task 4 is set (task 2 is cleared), the ball breaking process (task 4) is executed in the next loop, and this routine ends.

If the determination results in steps S106 and S108 are both "No", that is, if the number of winning balls to be ejected at the start of the current loop (number of rotations N) is greater than "2", Proceeding to S110, it is determined whether or not a ball is present at the tip 200D of the ball discharging device 200 and the ball is in a dischargeable state (whether or not the input signal from the count sensor I or II is at a high level). ). When the result of this determination is “No”, the aforementioned step S11
In step S2, the number of rotations is increased by "1", and in step S114, the step motor is idly rotated by the increased amount (180-degree rotation), and then the process proceeds to step S122 and later.

By the way, by adding "1" to the number of rotations in step S112 and rotating the stepping motor 180 degrees in step S114, the ball discharging device 200 operates as follows. That is, in the ball discharge control (task 2), once the discharge is started, the routine is continued until the discharge of a predetermined number (the number of balls to be discharged by executing the routine) is completed. During such control, a problem such as a ball not existing at the most downstream point of the worm (the position of the distal end portion 200D) may occur due to a problem such as ball clogging. When such a problem occurs, it is desirable that the clogged ball or the like be immediately eliminated and that the occurrence of the problem does not substantially affect the game (the game is not interrupted). Therefore, in the present embodiment, when the worm 251 of the ball discharging device 200 is controlled to rotate by a predetermined angle (180 degrees), it is determined whether or not a ball exists at the distal end portion 200D based on signals from the count sensors I and II. When none of the sensors I and II detects a ball, the number of balls ("1" in the present embodiment) that should have been ejected by this one rotation operation is determined this time. Is added to the number of balls “N” that should have been ejected by the series of ejecting operations described above, and the rotation operation is performed (idling in step S114), and the subsequent ball ejecting operation (steps S110, S116 to S126)
Is performed based on the added value. As a result,
The idle rotation is performed until the tip portion 200D is replenished with balls, and the discharge operation of the number of balls corresponding to the idle rotation is substantially performed by a predetermined number of ball discharge controls set at the beginning of the discharge operation. At the end of the operation (N rotation operations), it is additionally performed subsequently. Incidentally, the step S1
When the determination result of No. 10 is “Yes”, the tip 200
Since there is a ball to be ejected to D, the step motor is set to a speed (the speed set in any of the above-described steps S86 and S88) according to the playing state in order to perform a normal operation of ejecting the prize ball. And rotate (step S116)
The process proceeds to step S118 and subsequent steps.

Next, in step S118, it is determined whether or not a prize ball has been actually ejected (count sensor
Whether the input signals from I and II have fallen), and if the determination result is “Yes”, the step motor
After waiting for the rotation (the determination result of step S120 turns to "Yes"), the process proceeds to step S122. On the other hand, the determination result of step S118 is “No”
In this case, the processes of steps S116 and S118 are repeatedly executed until the step motor rotates 180 degrees (until step S128 changes to "Yes").
If the ball has not been ejected despite being rotated by degrees (when the determination in step S118 is “No” and the determination in step S128 is “Yes”), the processing proceeds to the above-described processing in step S146 and subsequent steps. , Tip 2 of ball discharge device
The control corresponding to the case where the ball clogging occurs in 00D is executed.

The prize balls are discharged by executing step S116, and the determination result in step S120 is "Y".
es ", the process proceeds to step S122,
Whether the number of rotations (corresponding to the discharge of prize balls at the normal discharge speed) by executing the processing in steps S100 and S116 to S1126 is a value smaller by "2" than the set value (number of rotations N) at the start of the routine. No, that is, it is determined whether the number of balls to be ejected is one remaining by the routine. While the determination result is “No”, the process proceeds to step S124, where it is determined whether or not the overflow switch is on. If the overflow switch has not yet overflowed, the overflow lamp remains off (step S126). Returning to step S110 to perform the next discharging operation, steps S110 and S110 are repeated until the determination result of step S122 changes to “Yes”.
Steps S116 to S126 are repeatedly executed (the prize ball discharge performed at this time is performed at one of two normal discharge speeds (a speed based on “motor speed data 1” or “motor speed data 2”)). .

If an overflow occurs during the discharge operation and the result of the determination in step S124 is "Yes", the overflow lamp is turned on (ON) in step S130, and step S1 is performed again.
A determination at 24 is made. That is, while the overflow state continues, only the steps S124 and S130 are repeated, and the overflow state is achieved by the players moving the ejected prize balls from the tray 17 (FIG. 1) to the "ball box". When it is released, the result of the determination in step S124 becomes "N" again.
Then, the discharge of the prize ball is restarted.

The discharge control (discharge at the normal discharge speed) of the prize balls other than the first one and the last one is completed.
When the number of balls to be ejected becomes one, the determination result of step S122 changes to "Yes" and step S1 is performed.
The process after 32 is started. In step S132,
As described above, whether or not the ball discharge device 200 is capable of discharging the ball (whether or not there is a ball at the tip 200D) is determined by:
The determination is made based on the input signals from the count sensors I and II. If the determination result is "No", the idling control in steps S112 and S114 is executed, and the processing is performed again from step S122.

On the other hand, if the decision result in the step S132 is "Yes", the process proceeds to the step S134, where the step motor is rotated according to the "motor delay speed data 2", and the last one is actually discharged. It is determined whether or not the sheet has been ejected (step S136). If the sheet has been ejected, the process waits until the 180-degree rotation of the step motor is completed (step S138 returns “Y”).
es "), steps S142 and S14
Execute Step 4. That is, it is determined that the discharge of the number N of prize balls stored at the start of the prize ball discharge processing is all completed, and the task 3 is set so that the safe ball processing (task 3) is started in the next loop. I do.

If the step motor has completed the 180-degree rotation before the last prize ball to be discharged is discharged ("Yes" in step S140), it is determined that the ball is clogged. The processing after step S146 described above is performed so that the ball breaking process (task 4) described later is executed in the next loop. (At this time, “1” is stored as the rotation number data in step S146.)

During the discharging process of the prize ball, the tip 20
Ball clogging occurs in 0D, the routine is interrupted once,
When the ball breaking process is performed, the prize balls to be discharged in the next prize ball discharge process (discharge process when restarted) based on the rotation angle of the step motor at that time as described above. The number (number of rotations N) is calculated and stored, and as will be described in detail later, at the end of the ball breaking process, the prize ball discharging process (task 2) is restarted based on the stored data. I have.

Next, the safe ball processing (task 3) performed in step S14 of the main routine (FIG. 18) will be described with reference to the flowchart of FIG. This safe ball processing is performed when task 3 is set, that is,
This is performed when the discharge of a predetermined number (7 or 15) of prize balls corresponding to one safe ball (winning ball) is completed (when step S144 of task 2 is executed). When this routine is started, first, the safe sensor 83
It is determined whether or not 1 (FIG. 2) detects a safe ball, that is, whether or not the input signal from the safe sensor is at a high level (step S160). In the present embodiment, the corresponding safe balls are collected only after the predetermined number of prize balls have been discharged, so if no safe balls exist at the start of this routine (the determination result is “ No "), it is determined that some kind of fraud has occurred, and the process proceeds to step S162, where the discharge device 600 sends a fraudulent signal to a fraudulent signal processing unit (not shown) on the management device side.
The occurrence of fraud is reported.

On the other hand, if the decision result in the step S160 is "Yes", the safe solenoid 833 is excited (ON) in a step S164, and then it is determined whether or not the safe sensor detects a safe ball. (Step S166). If the result of this determination is “No”, that is, if the safe ball has not yet been collected despite the safe solenoid being excited, it is determined in step S168 whether a predetermined time (eg, 200 msec) has elapsed after the solenoid was excited. Is done. Until the predetermined time elapses (the determination result is “No”), steps S164 to S164 are performed.
If S168 is repeatedly executed and the safe ball is collected during that time (when the determination result of step S166 turns to "No"), the process proceeds to step S170, and the above-described communication processing (FIG. 21) is performed in the next loop. ) Is performed (task 3 is cleared), and then a discharge number signal indicating that the discharge of a predetermined number of prize balls to one safe ball and the collection of the safe balls is completed is transmitted to the management device. Then (step S172), this routine ends. on the other hand,
When the determination result of step S168 is "Yes",
That is, after the safe solenoid is excited, a predetermined time (2
If the safe ball has not been collected even after the elapse of 00 msec), it is determined that some kind of fraud has been performed, and the process proceeds to the above-described step S162 to transmit a fraudulent signal to the management device to perform fraudulent processing. Has become.

Next, the ball clogging process (task 4) performed in step S16 of the main routine (FIG. 18) will be described with reference to the flowchart of FIG. This ball clogging process is performed when task 4 is set, that is, when ball clogging occurs during execution of the prize ball discharging process (FIG. 22) (set in step S150), or a ball removing process to be described later. (FIG. 25) When ball clogging occurs during execution (FIG. 25)
Is set in step S230), and is performed in a loop immediately after that.

When this routine is started, first, in step S180, the ball-busting solenoid 280 (FIG. 6) provided in the ball discharging device 200 is excited (ON) / demagnetized at regular intervals over a predetermined time. (OFF) is repeated, whereby the ball channels 259a and 259 of the ball discharging device 200 are turned off.
b is vibrated. After the ON / OFF control, in the next step S182, the step motor is rotated a predetermined number of times in the direction opposite to the rotation at the time of discharging, and then in step S184, the step motor is rotated forward by the same number of rotations. A series of such operations (vibration of the spherical flow path / motor reverse rotation / forward rotation) (ball clogging release operation) are continued a predetermined number of times (n times). That is, in the next step S186, it is determined whether or not the above-described series of operations has been performed a predetermined number of times (n times). If the determination result is “No”, it indicates that the clogging release operation has not been completed yet. A ball clogging signal is transmitted to a ball clogging signal processing unit (not shown) of the management device (step S188), and the operation is performed at the predetermined times (n).
Steps S180 to S188 are repeatedly executed until the number of times has reached.

When a series of ball clogging release operations are performed the above-mentioned predetermined number of times and the result of the determination in step S186 turns to "Yes", the flow advances to step S190 to determine whether or not the flag D is set. This flag D indicates whether the ball clogging has occurred during the above-described prize ball discharging process (task 2) or during the ball removing process (task 5) described later, in other words, the start of this routine. This is to determine whether the prize ball discharging process or the ball removing process has been performed in the immediately preceding loop. The flag D is set in step S230 of the ball pulling process (task 5) described later.

Therefore, if the determination result in step S190 is "No", task 2 is executed in step S192 so that the prize ball discharge processing is performed again in the next loop when the above series of ball clogging processing is completed. Is set (task 4 is cleared), and in step S196, the transmission of the ball clogging signal to the management device is stopped to indicate that the ball clogging process has been completed, and this routine ends. On the other hand, if the determination result in the step S190 is "Yes", the task 5 is set (the task 4 is cleared) and the flag D is cleared so that the ball removing process (FIG. 25) described later is restarted in the next loop. (Step S194), Step S1
After performing step 96, the routine ends. Even if the processes of steps S180 to S188 are performed a predetermined number of times (n times), even if the clogging of the ball is not actually solved, the routine is temporarily terminated and the process proceeds to the prize ball discharging process or the ball removing process. However, in this case, the clogging is detected again during these controls, and the routine returns to this routine to restart the clogging process from the beginning.

Next, the ball removing process (task 5) performed in step S18 of the main routine (FIG. 18) will be described with reference to the flowchart of FIG. When a ball-pulling operation rod is inserted into an insertion hole (both not shown) provided in the front panel 11 of the gaming machine and a ball-pulling sensor (not shown) detects that, a signal from the sensor is output. The rise is detected in the input process (step S30) of the interrupt process (FIG. 19). Then, when the rising of this signal is detected, the task control process executes task 5 on the condition that no other process is executed.
Is set, and this routine is started. When this routine is started, first, in step S200, the step motor is rotated according to the aforementioned “motor delay speed data 2”, the discharge of the ball by the ball discharge device 200 is started, and the ball removal solenoid 820 is excited. (ON), the flow path of the ball is switched to the ball drain gutter 815 side by the action of the flow path switching valve 821 shown in FIG.

In the next step S202, the count sensor
It is determined whether the input signal from I or II has fallen. When the result of this determination is "Yes", that is, when it is detected that the ball has been ejected from the tip portion 200D of the ball ejection device, the process waits for the step motor to rotate 180 degrees (step S204), and then the process from step S208 onward. Perform On the other hand, if the result of the determination in step S202 is "N
If o ", that is, if the ball has not yet been ejected even when the rotation of the step motor is started, step S206
Is executed, the step motor is rotated by 180 degrees. During that time, steps S200, S202, S206 are performed.
Is repeated, and if there is any discharge during that time (at this time, steps S202 and S204 become “Yes”), the processing after step S208 is executed. Meanwhile, 1
If the ball has not been ejected even after turning by 80 degrees (the determination result in step S206 is "Yes"), it is determined that there is no ball in the ball ejection device, and the processing from step S220 described below is executed. In the processing after step S220,
As will be described later in detail, once the ball-pulling process is automatically stopped (steps S220 to S224), and when the ball clogging is not resolved by the rotation of the worm in the automatic stop process (the count sensors I and II are set to the ball sensors). Is detected), and after executing steps S210 to S214 to be described later (in this case, step S214 is “No” and step S214 becomes “Yes” after rotating 180 degrees),
In step S230, a flag D is set to store that the ball has been clogged during the ball removing process, and a task 4 is set in the next loop so that the above-described ball clogging process (FIG. 24) is performed. Then, the process proceeds to step S232 described below,
Task 5 is cleared and this routine ends. As a result, when ball clogging occurs during the ball-pulling process, the ball-pulling process is temporarily interrupted, and in ball-pulling process (task 4), on / off control of a ball-smashing solenoid, predetermined number of reverse rotations of the step motor are performed. A series of crushing operations of the same number of forward rotations are continuously performed a predetermined number of times (n times), and after the crushing process is completed, the ball removing process is performed again.

On the other hand, in the processing after step S208 which is performed after the ejection of the ball by the ball removing operation is detected, first, it is determined whether the ball to be ejected next is located at the tip 200D of the ball ejection device 200. No (Count sensor I
Or whether the input from II is at a high level) (step S208). When the result of this determination is "Yes", the stepping motor is rotated in accordance with the "motor speed data 2" to discharge the second and subsequent balls at a high speed (step S210), and the next step is performed. S21
In step 2, it is determined whether or not the ball has been ejected (whether or not the input signal from the count sensor I or II has fallen). If the result of this determination is "No", the process proceeds to step S2.
At 14, it is determined whether or not the step motor has rotated 180 degrees, and as long as the determination result is "No", steps S210 to S214 are repeatedly executed. And 180
If the discharge has not yet been performed after the rotation has been completed (step S214 turns to "Yes"), it is determined that ball clogging has occurred, and the process proceeds to step S230. A task 4 is set to be executed, a flag D is set to store that the ball is being clogged, and the task 5 is cleared in step S232, followed by terminating the present routine.

The ball is ejected before the step motor rotates 180 degrees (the control result in step S212 is "Ye
s ") and when the 180-degree rotation has been completed (when the determination result in step S216 has turned to" Yes "), whether or not the signal from the ball removal sensor has risen again during the 180-degree rotation If the result of the determination is "No", that is, if the switch has not been pressed again after the initial ball release switch pressing operation, it is determined whether or not the ball has been pressed again (step S218). The process returns to step S208 to continue the punching process, and thereafter, repeats steps S208 to S218.If the ball release switch is pressed again by the staff during the ball punching process (the determination result in step S218 becomes " Yes "), the processing after step S228 described later is executed to stop the ball-pulling processing. The determination of whether or not there has been signal rise (reenter the high-level signal), the worm 25
1 is rotated 180 degrees (Step S216 is “Ye
s "), the warm 25
The stop of the ball-pulling process is permitted only when the ball 1 is actually rotated by 180 degrees. Therefore, the rotation position of the worm at the end of the ball-pulling process is always constant (the tip portion 200D).
(FIG. 6).

When all the balls in the ball discharging device 200 have been discharged by the ball removing process in steps S208 to S218, the determination result in step S208 becomes "N".
Then, the process proceeds to step S220, and the processes after step S220 are performed.
That is, in step S220, the step motor is rotated a predetermined number of times (n times) -1 time, and then the step motor is rotated according to the aforementioned "motor delay speed data 2" (step S222). The motor is stopped (step S224). As a result, after it is determined that the ball has been lost by executing the ball removing process (step S2).
08 is “No”), the stepping motor is further rotated a predetermined number of times, and then automatic stop of the ball removing process is performed. In this way, by automatically rotating the stepping motor a predetermined number of times after the detection of the absence of the ball and then automatically stopping the removal of the ball, if the ball is not continuously stored in the groove of the worm (input from the sensor). The signal is set to a low level), so that even if it is erroneously determined that the ball removal is completed, the ball removal process is not immediately terminated. When the sphere stored on the upstream side reaches the sensor position due to the rotation of the worm during the automatic stop operation, the fact is detected by executing step S226 (whether there is a count sensor ball) and the ball removal process is performed again. (Step S210
Is executed. In addition, the reason why the rotation of the step motor immediately before the automatic stop is delayed as described above is to accurately control the stop position of the step motor that has been rotating at a high speed until then.

When the step motor is automatically stopped in step S224, it is determined in step S226 whether a ball is present at the tip 200D of the ball discharging device (input signals from the count sensors I and II are high). Level or not). This determination result is “No”, that is,
If there is no ball at the tip portion 200D when the motor is stopped, it is determined that ball removal has been completed, and the process proceeds to step S228. The ball-pulling solenoid, which has been excited up to this point, is demagnetized (OFF), the task 5 is cleared in step S232, and this routine ends. (If the balls remain in the ball discharging device 200 after the motor is stopped as described above, the above-described step S2
Returning to 10, the ball emptying is started again. )

Next, step motor positioning processing (task 6) performed in step S20 of the main routine (FIG. 18) will be described with reference to the flowchart of FIG. This routine is started when it is determined that the ball discharge device 200 is not yet in the initial state, and the task 6 is set in step S79 of the above-described communication processing (task 1). When this routine starts,
First, in step S240, the step motor is rotated once (180 degrees) according to “motor delay speed data 2”. In the next step S242, the tip 2 of the ball discharging device
It is determined whether there is a ball at 00D (whether the input signal from the count sensor I or II is at a high level), and if the determination result is “No”, the motor is temporarily stopped (step S244) and the predetermined time ( After waiting for elapse of, for example, 500 msec (step S246), a signal indicating that initialization is in progress is transmitted to an initialization signal processing unit (not shown) of the management device (step S248), and the process returns to step S240. The process returns (this process is repeated until the ball is located at the tip 200D). On the other hand, step S24
2 is “Yes”, the leading end 200D
It is determined that a ball to be ejected is present (the initial positioning of the step motor has been performed), and the rotation of the step motor is stopped at that time (step S25).
0), and in the next step S252, task 1 is set so that communication processing is executed in the next loop (task 6 is cleared), and a signal (initial setting signal) indicating that the initial setting is being performed is sent to the management device. Stop transmission (step S25)
4), end this routine.

As described in detail above, according to the ball discharging device 200 of the first embodiment, the ball is discharged while detecting the discharge of each ball by the rotation of the step motor. Once the discharge of a predetermined number of balls by the operation control of the ball discharge device is started, it is determined every time the worm rotates whether or not a ball is present at the tip portion 200D, and no ball is present. Sometimes, the idle rotation is performed until it is present, and the number of idle rotations is added to the number of rotations “N” corresponding to a predetermined number at the beginning of the control, so that the discharge control is continued. Even if an abnormality such as a clogged ball occurs in the ejection device, the abnormality is resolved by the idle rotation of the worm, and the normal ejection of the ball and the ejection of the ball for the idle rotation are additionally performed. And will be done continuously

When the task 7 is set in the above-described task control process (step S6 in FIG. 18), a game ball purchase / payout process (task 7) is performed by the ball discharging device 200 having the above configuration. This purchase payout process is performed when the ball discharge control device 600 receives a purchase payout signal from the ball rental machine 20 (this input is determined in the above-described input process (step S30 in FIG. 19)). Based on the result, when the task 7 is set in step S68 of the above-described communication processing (FIG. 21), the processing is started. That is, when there is a purchase payout signal from the ball lending machine 20 side, the number of game balls to be lent to the player is calculated based on the content of the signal, and based on the calculated value, the stepping motor of the step motor is calculated. The number of rotations N is determined, and the step motor is actually rotated by that number of times.

Since the worm of the ball discharging device 200 of the above embodiment has one groove and is formed in a spiral shape, each time the worm rotates 360 degrees, the left and right ball channels 259 are formed.
a, one ball is discharged from 259b, a total of two balls are discharged (one ball is discharged every 180 degree rotation), but two or more grooves are spirally provided. A worm may be used instead. If a worm in which two grooves are spirally used is used, two spheres will be discharged from the right and left flow paths every 180 ° rotation, and a total of two spheres will be discharged using this relationship. What is necessary is just to perform discharge control. Further, in the ball discharge device 200 of the above embodiment, two ball channels are provided, but the number of ball channels is not limited to this, and may be one or three or more. Even when the number of ball channels is changed in this manner, the rotation angle of the step motor and the number of balls to be discharged can be kept in a fixed relationship, and a desired ball discharge control may be performed based on the relationship. . In the ball discharge device of the present embodiment, the rotation axis of the step motor and the rotation axis of the worm are coaxial so that they rotate at a ratio of 1: 1.
