However, in the pachinko ball ejecting apparatus using the pulse motor as described above, the heat generation amount of the pulse motor is relatively large, and the thermal influence on the electronic devices arranged in the vicinity is high. There was a problem that was inevitable. In particular, a large number of pachinko game machines are arranged adjacent to the island facility of a game store, and the island facility has a small free space, so that hot air tends to be trapped and the above-mentioned problems are remarkable. The present invention has been made in view of the above circumstances, and an object thereof is to provide a pachinko ball discharging device that can suppress heat generation, and reduce the thermal influence on electronic devices and the like arranged in the periphery.

Semicircular notches for inserting pachinko balls at equal intervals are formed, and a gear-shaped notch disk equipped with a gear at the center and the gear of this notch disk are fitted, and rotation of the notch disk can be prohibited. Notch disc stop member, stop member driving means for driving the notch disc stop member, a pulse motor for rotating the notch disc, a guide passage for guiding a pachinko ball to the notch disc, and a notch facing the guide passage. A ball detecting means which is arranged on the lower side of the disk and detects a pachinko ball sent by a notched disk, and 2-2 phase excitation at the initial and final stages of rotation of the pulse motor, and 1 during rotation.
Pulse motor rotation control means for performing −2 phase excitation.

[0006]

In the pachinko ball ejecting device of the present invention, the pulse motor is operated at the initial stage and the final stage of the rotation of the pulse motor.
The phase motor is driven and the pulse motor is driven by the 1-2 phase excitation after the pulse motor is started, that is, during rotation. Therefore, a large torque can be obtained at the initial stage of rotation and a final stage of rotation, which requires a large torque, and heat generation can be suppressed during rotation. The impact can be reduced.

Next, the operation of this embodiment will be described. In this embodiment, the ball ejection control device 902 executes the processing shown in the flowcharts of FIGS. 7 to 11. In the ball discharge control device 902, the process (main routine) shown in the flowchart of FIG. 7 is repeatedly executed every 1 ms by interruption processing when the main body of the gaming machine 1 is turned on.

In the main routine, as shown in FIG.
First, an input process is performed in step S1. In this input processing, for example, logic conversion from various detection switches and chattering prevention processing are performed. As the chattering prevention process, for example, there is a process for preventing chattering by taking into consideration the time constant of noise by performing a process of reading the signals from various detection switches twice by software.

Next, in step S2, it is determined whether or not the power is turned on. If the power is turned on, that is, if the routine is executed for the first time, the process proceeds to step S3 and the stored data in the RAM is erased (RAM clear). And initial setting is performed in step S4. As a result, the working area of the RAM is cleared, the flags are set, the output ports are reset, and the subroutine is initialized. And after this, it will be waiting for an interrupt,
The main routine is repeatedly executed from step S1 by a soft interrupt every 1 ms.

On the other hand, if it is determined in step S2 that it is not the first routine execution, that is, if it is the second or later execution, output processing is performed in step S5. In this output processing, processing such as data output to the output port and switching signal output to the solenoid is performed. Then, step S
At 6, the switch input monitoring process is performed. This input monitoring process monitors the input information of each sensor and switch, and specifically, the discharge sensor 771 and the half-end sensor 160.
And the output signals of the overflow sensor 59 and the like are monitored.

Next, in step S7, a ball payout start confirmation condition monitoring process is performed. This ball payout start confirmation condition monitoring process confirms whether or not the conditions for starting the discharge for a prize ball or ball lending are satisfied in the pachinko ball discharge device 804. For example, "a winning ball (safe ball) Confirmation is performed based on data such as "yes" or "there is a ball lending request signal".

In the following step S8, corresponding steps A to S are performed based on the result of the input monitoring process of each switch.
Processing for branching to step G is performed. Then, the following processing is performed in each branch destination step. Step A: Confirm safe balls and confirm purchase. This is because it is necessary to confirm that a safe ball has been generated due to winning, and that the player operates the conversion button 31 to purchase a pachinko ball and a ball lending request signal or a ball lending unit signal is generated. This is because it is necessary to confirm that they have been received.

Step B: Award ball data transmission / reception processing is performed. This is to receive award ball data and, when receiving award ball data, output it. Step C: Perform discharge start processing of prize balls and loan balls. By executing this process, the pachinko ball ejecting device 804 starts operating, and prize balls or lending balls are paid out.

Step D: A pachinko ball ejection process is performed. This process is performed in order to prevent ball clogging by slowing down the operation of the pachinko ball ejecting device 804 immediately before the number of ejected pachinko balls reaches the specified number. Step E: Perform discharge end processing. By this ending process, the operation of the pachinko ball discharging device 804 is stopped, and the payout of the prize ball or the rental ball is ended. The processing of steps D and E described above will be described in detail later.

Step F: Safe ball payout and wait processing are performed. In this processing, the safe solenoid 79 of the winning ball processing apparatus 801 is completed at the time when the discharge of the winning balls is completed.
When 1 is turned on once to eject only one safe ball this time, and when the next prize ball is continuously paid out, a certain wait time is provided between the ball ejecting operations for smooth operation. The discharge operation is executed.

Step G: A ball removing process is performed. this is,
This is for discharging the pachinko balls existing in the back mechanism 800 such as the storage tank 806 to the recovery flow path of the island facility by operating the ball pulling solenoid 58. When the ball punching operation is performed, that is, the game machine 1 is operated by a staff member. When the ball punching switch 161 detects that the ball punching rod has been inserted into the operation hole on the front side of, the pachinko ball discharge path is switched and the downflow gutter 808 is communicated with the ball cutting trough.

After any one of the steps A to G, the process proceeds to step S20 to control various solenoids. This is to set the drive information of the corresponding solenoid according to a predetermined step state. In particular, in this step S20,
When the branching step described above is a process related to the discharge of pachinko balls, the solenoid 72 of the stopper mechanism 720
2 is energized to disengage the stopper 721 from the gear 713 so that the pachinko balls can be discharged. Next, step S
At 21, the control process of the pulse motor 750 is performed. this is,
The drive phase of the pulse motor is controlled to control its rotation. The control process of step S21 will be described later.

Next, a subroutine for executing each processing of step D, step E and step 21 in the above main routine will be described. As shown in FIG. 8, the subroutine of step D first determines whether or not the number of pachinko balls ejected by the ejection mechanism 710 in step S30 is in a state in which “−1” is subtracted from the prescribed number. For example, if 15 prize balls are to be ejected, the “regular number = 15”, and in step S30 it is determined whether or not the number of ejected pachinko balls is the 14th.

Then, the determination result of step S30 is No.
If (for example, less than 14th), the process returns to the main routine. This sets the operating speed of the pachinko ball ejecting device 804 to the normal state until it reaches the 14th ball, and when it reaches the 14th immediately before stopping, slows down the operating speed and delays the ejection of the 15th pachinko ball. This is for preventing the ball damage and accurately stopping the pulse motor 750.

The determination result of step S30 is Yes.
If (for example, the 14th time), step S3
The process proceeds to 1 and the branch step in the main routine is set to "E", and the process returns to the main routine. This allows
After returning to the main routine, the process of step E (discharge end process) is performed.

The subroutine of step E is shown in FIG.
First, in step S40, it is determined whether or not the number of pachinko balls ejected by the ejection mechanism 710 is the prescribed number of ejected balls. If the number is (Y), the process proceeds to step S41. In step S41, the branch step in the main routine is set to "F". Then, as will be described later, the process of step F (safe ball payout and wait process) is performed when the process returns to the main routine by setting the branch step to "F".
The safe solenoid 791 is energized. That is, when the discharge of the specified number of prize balls is completed, the safe solenoid 791 of the winning ball processing device 801 is turned on once, and only one safe ball this time is discharged.

Then, in step S42, a wait timer is set. This is to set a timer for counting the wait time, although a fixed wait time is provided when prize balls are paid out continuously. For example, 200 ms is set as the wait time. With the setting of the wait time, when the prize balls are continuously paid out, the start of the pachinko ball discharging operation is delayed by an amount corresponding to a certain wait time.

Further, in the solenoid control process of step S20, a subroutine shown in FIG. 10 is executed. First, in step S101, it is determined whether or not the processing of the branch step in the main routine this time is steps C, D, E, and G, that is, whether or not the processing is related to the discharge of pachinko balls. If it is determined that the process is related to discharge (Yes), the process from step S102 is executed, and if not the process related to discharge (No), the process from step S107 is executed. In step S102, the ON information of the stopper solenoid 722 is set to drive the stopper solenoid 722, and in step S107, the OFF information of the stopper solenoid 722 is set to stop the energization of the stopper solenoid 722.

In the following step S103,
It is determined whether or not the process of the branching step is step G, that is, the punching process, and if it is the punching process (Yes).
After executing the processing of step 104, step S106
Processing is performed, and if it is not the punching processing (No), the processing of step S105 is performed, and then the processing of step S108 is performed. In step S104, ON information of the ball-punching solenoid 58 is set to energize the ball-punching solenoid 58, and in step S105, OFF information of the ball-punching solenoid 58 is set to stop energizing the ball-punching solenoid 58.

In step S106, it is determined whether or not the stopper solenoid 722 is off timing, and if it is off timing (Yes), the process of step S107 is performed and the process proceeds to step S108. If it is not off timing (No) step The process of S108 is performed. In step S107, the OFF information of the stopper solenoid 722 is set as described above.

In step S108, it is determined whether or not the branch step is step F. If the branching step is step F (Yes), step S109
To set the ON information of the safe solenoid 791 to energize the safe solenoid 791. If the branch step is not step F (No), the OFF information of the safe solenoid 791 is set to drive the safe solenoid 791 in step S110. To stop.

Furthermore, in the pulse motor control processing of step S21, the subroutine shown in FIG. 11 is executed.
First, in step S50, a ball crush process is performed. As described below, the pachinko ball is guided by the pachinko ball 702 in the ball degumming process.
And the like, and whether or not the pachinko ball is bitten by the sprocket 712 is monitored, and if the ball is jammed or bites into the sprocket 712, processing for eliminating it is performed. Is to do.

Next, in step S51, it is determined whether or not there is a reset wait flag. If the reset wait flag is set (Yes), the process returns to the main routine, and if there is no reset wait flag (N).
o) The process of step S52 is performed. As will be described later, this reset wait flag is set when the ball game is not released in the ball game process of step S50.

In step S52, it is determined whether or not the ball gami flag is set. If the ball gami flag is set (Yes), the process of step S64 described later is performed, and if the ball gami flag is not set. (N
o) The process of step S53 is performed. As will be described later, this ball gami flag is used when it is determined that a ball clogging of the game ball in the guide passage 702 or the like or the biting of the game ball into the sprocket 712 occurs in the ball gamming process of step S50, that is, the ball gami. It is set when it is determined to be the occurrence state.

In step S53, the processing of the branch step in the main routine this time is performed in step C,
It is determined whether the processing is D, E, or G, that is, whether the processing is related to the discharge of pachinko balls. And
If it is not the discharge process (No), OFF data is set in step S54 to not energize the pulse motor 750, and if it is the discharge process (Yes), step S55.
The process of is executed.

In step S55, it is determined whether or not the pulse control timer is 0, and the pulse control timer is 0.
If not, the process of step S63 is performed after updating the timer in step S56, and if it is determined that the pulse control timer is 0, that is, the update time of the pointer (described below) has expired, the process of step S57 is performed.

Here, the pulse control timer counts the update time of the pointer of the motor control data for controlling the drive phase of the pulse motor 750, and the motor control data is the time for the phase control of the pulse motor 750. It is dynamic data. This motor control data is designated by a plurality of pointers (four pointers “1” to “4” are illustrated), and when the pulse motor 750 is rotated in the normal direction, the pointer is moved in the forward direction (“1” → “4”). When the pointer is incremented and reversed, the pointer moves in the opposite direction ("4" →
Decremented to "1").

In step S57, it is determined whether or not the branch step of the main routine to be executed this time is step E, that is, whether or not the discharge end process is being performed. Then, if it is not the discharge end process (No), the timer 1 is set in step S58 and the process of step S61 is performed. If it is the discharge end process (Yes), the timer 2 is set in step S59 and then in step S60. Set the motor control pointer to "+
Increment by 1 ”. Since the timer 1 counts up the pointer update time at a timing faster than that of the timer 2, the rotation speed of the pulse motor 750 becomes slow in the case of the discharge end processing, and the pachinko balls can be prevented from being caught in the sprocket 712. .

In step S61, it is determined whether or not the branch step of the main routine to be executed this time is step C, that is, whether or not it is the discharge start process. In this step S61, if it is determined to be the discharge start processing (Yes), the motor control pointer is decremented by "-1" in step S62, and if it is determined not to be the discharge start processing (No), the above-mentioned is performed. In step S60, the motor control pointer is incremented by "+1".

In the following step S63, whether or not the branch step of the main routine to be executed this time is step D,
That is, it is determined whether or not it is a discharge process. If it is not the discharge process (No), that is, the branching steps are C, E,
If it is any one of the G discharge start process, the discharge end process, and the punching process, the 2-2 phase table is set in step S64. If it is the discharge process (Yes), the 1-2 phase table is set in step S65. These tables set the pulse application method to the pulse motor 750, that is, the energization method of the multi-phase winding. When the 1-2 phase table is set, the 1-2 phase excitation and the 2-2 phase table are set. When set, 2-2 phase excitation is performed.

By performing steps S63, S64, and S65 described above, in the case of the discharging process, that is, when the pulse motor 750 is driven by the 1-2 phase excitation during the rotation of the pulse motor 750 and is not the discharging process. , That is, 2 at the beginning or end of rotation of the pulse motor 750.
The pulse motor 750 is driven by the −2 phase excitation. Therefore, at the beginning or end of rotation of the pulse motor 750, a large torque can be obtained in the output of the pulse motor 750 to ensure smooth rotation.
It is possible to reduce the heat generation amount of the pulse motor 750 during the rotation of 50.

Next, in step S66, control data such as the drive phase of the pulse motor 750 is calculated by the motor control pointer, and the control data calculated in the following step S67 is set in the output buffer and output. Then, upon completion of step S67, the process returns to the main routine.

Further, the ball crush processing in step S50 is shown in FIG.
2 and the routine shown in FIG. 13 is executed.
First, as shown in FIG. 12, in step S70, it is determined whether or not there is a reset wait flag. If the reset wait flag is set (Yes), the processes from step S71 to step S73 are performed to execute the pulse motor. If the process returns to the control processing subroutine and the reset wait flag is not set (No), step S7
The processing after 4 is executed. The reset wait flag will be described later.

In step S71, the reset switch 7
If it is determined that the reset switch 799 has been reset (Yes).
s), the reset wait flag is cleared in step S72, and when it is determined that the reset switch 799 has not been reset (No), each motor and each solenoid is turned off in step S73. Then, after the completion of step S73, the process returns to the subroutine (pulse motor control process). As described above, the reset switch 799 is turned on by an attendant when resetting the operation of the pachinko gaming machine 1.

In step S74, it is determined whether or not the pachinko balls are being ejected. If they are being ejected (Yes), the process proceeds to step S75, and if they are not being ejected (No), the process proceeds to step S78. In step S75, the discharge sensor 771
Whether or not the detection signal of is input is determined. When it is determined that the detection signal of the discharge sensor 771 is not input (N
o), that is, the emission sensor 7 even though it is being emitted
If the detection signal is not input from 71, it is determined that an abnormality has occurred, and the monitoring flag is set in step S76. Also,
When the detection signal of the discharge sensor 771 is input (Yes
s), the number of tries and the number of repetitions are cleared in step S77, and the monitoring flag is cleared in subsequent step S78.
As will be described later, the number of repetitions is defined as the number of times the pulse motor 750 is repeatedly rotated forward and backward, and one try is defined with this number of repetitions as a specified number.

Next, in step S79, it is determined whether or not the monitoring flag is set. Then, in this step S79, when it is determined that the monitoring flag is set (Yes), the process proceeds from step S80 to step S83 and then the process proceeds to step S85, and the monitoring flag is not set. If it is determined (No), the process proceeds to step S85 after performing the process of step S84. In step S84, the monitoring timer is cleared, assuming that the above-mentioned abnormal state has been resolved.

Further, in step S80, the monitoring timer is updated, and in the following step S81, it is determined whether or not the count time of the monitoring timer has reached the specified time. This step S
In 81, when the count time of the monitoring timer reaches the specified time, that is, the discharge sensor 77
If the abnormal state in which the detection signal is not input from 1 continues for the specified time (Yes), it is determined that a ball gami has occurred and the ball gami flag is set in step S82, and then step S
At 83, the upper limit of the monitoring timer is set. If the monitoring timer has not reached the specified time (No), step S
Proceed to 85.

In step S85, as shown in FIG. 13, it is determined whether or not the ball damage flag is set. If the ball damage flag is not set (No), the process returns to the pulse motor control process subroutine, If the ball flag is set (Yes), step S8
In step 6, it is determined whether the rotation direction of the pulse motor 750 is the forward rotation timing.

Then, in this step S86,
If it is determined to be the forward rotation timing (Yes), step S8
After incrementing the motor control pointer by "+1" in step 7, the ON information of the stopper solenoid 722 is set in step S88 to energize the solenoid 722, and
When it is determined that the reverse rotation timing is reached (No), step S89
After decrementing the motor control pointer by "-1", the stopper solenoid OFF information is set in step S90 to stop the energization of the solenoid 722. And
In step S91, the number of times the pulse motor 750 is normally and reversely rotated is updated.

Steps S87 to S9 described above
By repeatedly executing the processing up to 0, the sprocket 712 repeats forward and reverse rotation, and the stopper mechanism 72
0 means that the stopper 721 contacts the gear 713 every time the reverse rotation is made,
Pachinko balls staying in the guide passage 702 or the like are swung. That is, the pachinko balls staying in the guide passage 702 and the like are swung by the sprockets 712 and the like in a state in which the ball gami flag is set and it is determined that the ball gami has occurred. For this reason, it is possible to eliminate the ball damage. In particular, as will be described later, the forward and reverse rotations of the sprocket 721 described above are repeated a prescribed number of tries with a predetermined number of iterations as one try, so that the ball damage can be reliably eliminated.

Next, in step S92, it is determined whether or not the number of iterations has reached the prescribed number, and if the number of iterations has not reached the prescribed number (No), the process returns to the subroutine, and the number of iterations reaches the prescribed number. If it has reached (Ye
s) Clear the number of iterations counted in step S93. Here, if the number of iterations has not reached the specified number, the process returns to the subroutine and the step S70 is performed again.
Since the process from 1 is repeated, if the detection signal of the discharge sensor 771 is input on the way and it is determined that the ball defect has been eliminated (see step S75), the above-described iterative process is interrupted. Therefore, prompt discharge is achieved without repeating unnecessary repetition.

Subsequently, the monitoring timer is cleared in step S94, the number of tries is updated in step S95, and it is determined in step S96 whether the number of tries reaches the specified number. In this step S96, if it is determined that the number of tries has not reached the specified number (No), the process returns to the subroutine, and if it is determined that the number of tries has reached the specified number (Yes), the number of tries in step S97. After clearing, the reset wait flag is set in step S98. Then, as described above, when the reset wait flag is set, the energization of all motors, solenoids, etc. is stopped until the reset switch 799 is turned on (see steps S71 to S73). The above-mentioned number of tries is defined with the specified number of iterations as one try.

As described above, in the pachinko ball ejection device of this embodiment, the pulse motor 750 is used as the driving source for pachinko ball ejection, and when the pachinko ball ejection start process and the ejection end process are performed, that is, in the pulse mode. Motor 7
The pulse motor 750 is driven by 2-2 phase excitation at the initial stage and the final stage of the rotation of 50, and 1-2 is generated during the discharging of the pachinko balls, that is, during the rotation of the pulse motor 750.
The pulse motor 750 is driven by phase excitation.

Therefore, the pulse motor 750 can output a large torque at the start and end of the discharge to surely start and end the discharge, and the heat generation amount of the pulse motor 750 is reduced during the discharge. Therefore, the heat effect on the surrounding electronic devices can be reduced.

In the embodiment described above, the discharging mechanism 71
Although 0 has two sprockets 712, it is needless to say that it can be applied to all that employ the pulse motor 750 regardless of the number of sprockets of the ejection mechanism.

[0077]

According to the pachinko ball ejection device of the present invention, a pulse motor is adopted as an actuator for ejecting a pachinko ball, and the rotation start (start) of the pulse motor is started.
The pulse motor is driven by 2-2 phase excitation at the time of rotation and at the end of rotation, and the pulse motor is driven by 1-2 phase excitation during rotation of the pulse motor. Therefore, a large output torque can be output to the pulse motor at the start and end of pachinko ball ejection, which requires a large torque, to ensure the start and end of ejection, and after ejection has started. During discharging, the heat generation of the pulse motor can be suppressed to reduce the heat influence on the peripheral electronic devices and the like.
