Specifically, the start switch of the start lever 17, the stop switch of the stop buttons 18a to 18c, the input switch of the input buttons 15 and 16, the liquidation switch of the checkout button 14, and the photointerrupters PH1 and PH2 constituting the input number determination unit 21d These are connected to the blocker solenoid 30 and the various LED elements 9 to 11 constituting the inserted medal return unit 21c.

Has been. Then, by rotating or stopping the stepping motor, the rotating operation of the rotating reels 4a to 4c and the stopping operation at the target position are realized.

  The main control board 50 is also connected to the medal payout device 5 through the payout relay board 63. The medal payout device 5 is provided with a medal payout control board 55, a medal payout sensor SE, and a payout motor MO. The medal payout control board 55 is based on a medal payout signal PAY from the main control board 50. The payout motor MO is rotated to pay out a predetermined amount of medals. The payout motor MO is a DC motor such as a brush motor, and continues to rotate as long as it receives DC 24V.

  In addition, the main control board 50 is also connected to the external concentration terminal board 56 and the rotary setting board 54. The external concentrated terminal board 56 is connected to, for example, the hall computer HC, and the main control board 50 outputs the number of inserted medals and the number of paid out medals through the external concentrated terminal board 56. Further, the rotating setting board 54 outputs a setting key signal indicating the rank setting value of the probabilistic medal payout number set by the staff.

  FIG. 6A is a schematic diagram illustrating the connection relationship among the main control board 50, the payout relay board 63, and the medal payout control board 55. As illustrated, the medal payout control board 55 receives a medal payout signal PAY and DC24V (motor drive power supply) from the main control board 50 via the payout relay board 63. Each circuit board 50, 63, 55 is connected to an adjacent circuit board via wiring connectors CN1 to CN4.

  Here, the number of wires between the medal payout control board 55 and the upstream circuit board (50, 63) is three including the ground line, which is only easier to manufacture than the conventional circuit configuration. And the possibility of illegal activities can be reduced.

  The main control board 50 includes a signal output unit 70 that outputs a medal payout signal PAY (FIG. 6A). As illustrated, the medal payout signal PAY and DC24V are output from the wiring connector CN1 together with other signals including the ground signal. Further, as shown in FIG. 6B, at the time of the medal payout operation, the drive pulse SG becomes H level and returns to the L level after the pulse time width τ corresponding to the payout number of medals.

  As specifically shown in FIG. 6C, the signal output unit 70 receives the drive pulse SG, performs an output transistor Qa that performs a switching operation, a control transistor Qc that performs a switching operation in synchronization with the output transistor Qa, and a control And an energizing transistor Qb for energizing a 24V DC power supply line when the transistor Qc is turned on. Each of the transistors Qa to Qc is a bipolar transistor, and a PNP power transistor having a large current capacity is selected as the energizing transistor Qb. The transistors Qa and Qb are NPN type transistors.

  As shown in the figure, the base terminal of the output transistor Qa receives the drive pulse SG through the base resistor Ra, and the collector terminal receives the DC power supply Vcc5V. The emitter terminal of the output transistor Qa is connected to the wiring connector CN1 as the output terminal of the medal payout signal PAY.

  The base terminal of the control transistor Qc receives the drive pulse SG through the base resistor Rc, and the collector terminal receives DC24V (motor drive power supply) via the load resistor RL and the bias resistor Rb. The emitter terminal of the control transistor Qc is connected to the ground.

  On the other hand, the emitter terminal of the energizing transistor Qb receives a motor drive power supply 24V, and a bias resistor Rb is connected between the emitter terminal and the base terminal. The collector terminal of the energizing transistor Qb is connected to the ground via the capacitor Ca, and is connected to the wiring connector CN1 as the output terminal of the motor drive power supply 24V.

  Here, as the capacitor Ca, a large-capacitance capacitance element is selected, and power supply of DC 24V is started after an appropriate delay after the drive pulse SG becomes H level. After the drive pulse SG becomes L level, the capacitor Ca is moderate. After that, the power supply of DC24V is stopped (delay time τ).

  As shown in the figure, the medal payout signal PAY is supplied to the current inflow terminal of the photocoupler PC (light emitting diode D) of the medal payout control board 55, and the output current of the light emitting diode D passes through the current outflow terminal and the wiring connector CN1. Then, it is configured to be fed back to the ground of the main control unit 50. Therefore, when the output transistor Qa is turned on, the ON current = (Vcc−Vf) / Re defined by the emitter resistance Re and the voltage drop Vf of the photodiode D flows to the light emitting diode D of the photocoupler PC. .

  Since the signal output unit 70 is configured as described above, the control transistor Qc is turned ON during the payout operation in which the drive pulse SG becomes H level, and DC24V → bias resistor Rb → load resistor RL → transistor Qc → Collector current flows through the ground path. In this embodiment, since the voltage across the bias resistor Rb is designed to be about 1 V during this ON operation, the energizing transistor Qb is also turned on in response to the ON operation of the control transistor Qc. However, since a large-capacitance capacitor Ca is connected between the collector terminal of the energizing transistor Qb and the ground, the power supply that outputs the motor drive power 24V to the wiring connector CN1 is slightly delayed from the ON operation of the energizing transistor Qb. Operation starts.

  At the time of the payout operation in which the drive pulse SG is at the H level, the output transistor Qa is also turned on in parallel with the above operation, so that the drive of the payout motor MO is started in response to the ON operation of the photocoupler PC.

  On the other hand, when payout is prohibited when the drive pulse SG is at the L level, the reverse operation is performed. That is, the power supply of the motor drive power supply 24V is stopped after the OFF operation of the output transistor Qa and the photocoupler PC.

  FIG. 7 is a flowchart for explaining the medal payout operation by the main control unit 50 including the control of the drive pulse SG described above. First, it is determined whether or not the number of medals to be paid out to the player is 0 (ST10). If the number of medals paid out is not 0, the number of credits is increased until the number of credits reaches an upper limit (for example, 50). By doing so, the payout process is executed (ST11 to ST13).

  FIG. 7 is a flowchart for explaining the medal payout operation by the main control unit 50 including the control of the drive pulse SG described above. First, it is determined whether or not the number of medals to be paid out to the player is 0 (ST10). If the number of medals paid out is not 0, the number of credits is increased until the number of credits reaches an upper limit (for example, 50). By doing so, the payout process is executed (ST11 to ST13).

  On the other hand, when the number of credits reaches the upper limit value or reaches the upper limit value in this way, the medal payout signal PAY is set to the ON level (active level) (ST15). Specifically, the energizing transistor Qb and the output transistor Qa of the main control unit 50 are turned on, and the photocoupler PC of the medal payout control board 55 is turned on. As a result, the payout motor MO starts rotating and the payout of medals is started.

  Accordingly, it is next determined whether or not the payout sensor SE (FIG. 5) has detected a medal payout (ST16), and waits for a predetermined waiting time until a medal payout is detected (ST18). If a medal payout is detected, the payout number is subtracted (ST17), and the same operation is repeated until the remaining payout number becomes zero. On the other hand, if the payout sensor SE does not detect the payout of medals even after the predetermined standby time is exceeded, it is considered that the medal hopper 5a is empty, and an abnormality notification process to that effect is executed (ST19). When the opening / closing of the door sensor is detected, it is assumed that the replenishment process by the staff has been completed, the error notification process is canceled, and the process returns to step ST15.

  If such processing is repeated, the remaining payout number will eventually become 0 (ST13), so that the medal payout signal PAY is turned off and the processing ends (ST14). Specifically, the energizing transistor Qb and the output transistor Qa of the main control unit 50 are turned off, and the photocoupler PC of the medal payout control board 55 is turned off. As a result, the rotation of the payout motor MO is stopped.

  8 to 9 are drawings for explaining the medal payout operation. As shown in FIG. 8, the medal payout control board 55 includes a signal transmission circuit 81 using a photocoupler PC, a current limiting circuit 82 using bipolar transistors Q3 and Q4, a drive control circuit 83 using a MOS transistor Q5, and a MOS transistor Q6. And a braking circuit 84.

  The drive voltage DC24V supplied from the main control board 50 is transmitted to the payout motor MO via the polyswitch RT so that the payout motor MO rotates unless the energizing transistor Qb of the main control board 50 is in the ON state. It is configured.

  The polyswitch RT is a polymer-based PTC (Positive Temperature Coefficient) thermistor. When the element temperature rises above a predetermined value, the resistance value of 1Ω or less increases rapidly in the normal state to become about 104Ω to 106Ω. Have. For example, when an excessive current flows due to a short circuit of the wiring of the payout motor MO, the DC24V power supply line is opened due to the resistance value of the polyswitch RT.

  The light-emitting diode D of the photocoupler PC is configured to emit light when a forward current flows under the condition that the output transistor Qa is turned on. When the light emitting diode D emits light, the phototransistor Tr of the photocoupler PC is turned on. As shown in the figure, the collector terminal of the phototransistor Tr is supplied with a drive voltage DC24V, and the emitter terminal is connected to the current limiting circuit 82.

  The current limiting circuit 82 includes a PNP transistor Q3, a collector resistor R4, a bias resistor R10, a current detection resistor R13 of the payout motor MO, a bias resistor R5, a capacitor C1, an NPN transistor Q4, and a current limiting resistor R8. And a reverse current blocking diode D2.

  The emitter terminal of the transistor Q3 is connected to the emitter terminal of the transistor Tr of the photocoupler PC and the current limiting resistor R8. A current limiting resistor R8 and a diode D2 are connected in series between the emitter terminal and the base terminal of the transistor Q3, and the cathode terminal of the diode D2 is connected to the base terminal of the transistor Q3. The cathode terminal of the diode D2 is connected to the collector terminal of the transistor Q4, and the emitter terminal thereof is connected to the ground. The base terminal of the transistor Q4 is connected to the ground through a capacitor C1 and a resistor R5 connected in parallel.

  The base terminal of the transistor Q4 is connected to the source terminal of the N-channel MOS transistor Q5 through the resistor R10. A resistor R13 is connected between the source terminal of the N-channel MOS transistor Q5 and the ground to monitor the drive current of the payout motor MO. The current detection resistor R13 is about 0.51Ω.

  The drive control circuit 83 includes an N channel MOS transistor Q5, a bias resistor R9, and a capacitor C3. Here, the drain terminal of the MOS transistor Q5 is connected to the (−) terminal of the payout motor MO. A resistor R9 and a capacitor C3 connected in parallel are connected between the base terminal and the source terminal.

  The braking circuit 84 includes a P-channel MOS transistor Q6, bias resistors R11, R12, R6, and R7 for voltage division, a capacitor C2, and a reverse current blocking diode D1. The source terminal and drain terminal of the P-channel MOS transistor Q6 are connected to the (+) terminal and the (-) terminal of the payout motor MO, respectively. Therefore, when the P-channel MOS transistor Q6 is turned on, the driving of the payout motor MO is prohibited.

  On the other hand, a resistor R11 is connected between the source terminal and the gate terminal of the MOS transistor Q6, and bias resistors R12, R6, and R7 are connected in series between the gate terminal and the grant. The cathode terminal of the diode D1 is connected to the connection point between the resistor R12 and the resistor R6. On the other hand, the anode terminal of the diode D1 is connected to the emitter terminal of the transistor Tr of the photocoupler PC and the resistor R8.

  Based on the above, the medal payout operation will be described. First, the case where the energizing transistor Qb and the output transistor Qa of the main control unit 50 are turned on (ST15) will be described with reference to FIG. In this case, after the output transistor Qa and the photocoupler PC are turned on, the feeding operation of the motor drive power supply 24V is started after an appropriate delay time.

  Then, an ON current Ion flows through a path of DC5V → transistor Qa → emitter resistance Re → photocoupler light emitting diode D → ground line. For this reason, the phototransistor Tr of the photocoupler is also turned on, and the direct current passing through the transistor Tr flows in the path of motor drive power supply 24V → diode D1 → resistor R6 → R7.

  In addition, the direct current passing through the transistor Tr also flows through a path of resistance R8 → resistance R9 → resistance R13 and a path of resistance R8 → resistance R9 → resistance R10 → R5. As a result, the transistor Q5 is turned on, the motor drive current flows through the path of the polyswitch RT → the payout motor MO → the transistor Q5, and the payout motor MO rotates.

  At this time, the current limiting circuit 82 functions as a negative feedback circuit that prevents an excessive motor driving current from flowing. That is, since the motor drive current flows through the current detection resistor R13, if the motor drive current increases greatly, the base potential of the transistor Q4 increases, and the collector current flows through the resistor R8 → diode D2 path.

  Then, since the transistor Q4 and the transistor Q3 are connected to each other with a thyristor structure, an increase in the collector current of the transistor Q4 causes an increase in the collector current of the transistor Q3, and the transistor Q4 is connected via the resistor R5. By increasing the collector current more and more, the two transistors Q3 and Q4 form a positive feedback loop for ON operation.

  On the other hand, when the collector current of the transistor Q4 increases toward the saturation current, the potential of the anode terminal of the diode D2 drops, so that a negative feedback loop is formed to turn the transistor Q5 OFF. Therefore, an excessive motor drive current is prevented from flowing based on the operation of transistor Q5, and the motor drive current is maintained in a predetermined range.

  By the way, at the timing when the payout motor MO is driven, the transistor Q6 is in the OFF state. The current flows through the path of the resistor R11 → the resistor R12 → the resistor R6 → the resistor R7, and the current also flows through the path of the diode D1 → the resistor R6 → the resistor R7. This is because the saturation voltage VCE and the forward voltage drop VF of the diode are suppressed to VCE + VF≈1V.

  Next, based on FIG. 9, the operation when the energizing transistor Qb and the output transistor Qa of the main control unit 50 are turned off (ST13) will be described (payout stopped state).

  In this case, since the output transistor Qa is in the OFF state, no current flows through the photocoupler PC, and the transistors Q3, Q4, and Q5 are not in the ON state. However, because of the capacitor Ca, the power supply operation of the motor drive power supply 24V is maintained for a while. Therefore, a current flows through the path of the resistor R11 → the resistor R12 → the resistor R6 → the resistor R7 → the ground. Here, since the voltage across the resistor R11 is set to be 24 * R11 / (R11 + R12 + R6 + R7) ≈3 V, the transistor Q6 is turned on by the voltage between the source terminal and the gate terminal.

  Since the ON operation of the transistor Q6 is executed when the photocoupler PC transitions from ON to OFF, the driving current of the inductive dispensing motor MO is instantaneously absorbed as the collector current of the transistor Q6, and the dispensing motor The brake is applied to the rotation of the MO. Therefore, according to the configuration of the present embodiment, medals are not overpaid by the inertial force.

  As described above, according to the present embodiment, the medal payout control board 55 reduces the possibility of illegal acts. That is, even if the medal payout line PAY (emitter terminal of the output transistor Qa) is short-circuited to the ground in the payout stop state, the payout motor MO cannot be rotated because the transistor Qa remains off. .

  Even if DC24V is abused and the photocoupler PC is turned on, if the drive pulse SG becomes L level, the power supply operation of the motor drive power supply 24V is stopped after an appropriate delay time (τ). I cannot pay medal.

  Although the embodiments of the present invention have been specifically described above, the specific description is not particularly intended to limit the present invention and can be appropriately changed. For example, while the slot machine has been described in the previous embodiment, the present invention is preferably applied to a ball game machine that implements a game ball payout process with a DC motor.

  In the embodiment, a bipolar transistor is used. However, the transistor is not particularly limited, and an FET transistor may be used. As the energizing transistor Qb, it is also preferable to use an insulated gate bipolar transistor IGBT (Insulated Gate Bipolar Transistor). In addition, it is not necessary to use individual elements. For example, as shown in FIG. 10, an analog switch A-SW may be used.

  Furthermore, as shown in FIG. 11, it is also preferable to connect the main control board 50 and the medal payout control board 55 with two wires. In this case, rotation of the payout motor MO is started on the condition that the DC 24V motor drive power supply also serves as the medal payout signal PAY and the energizing transistor Qb and the control transistor Qc are turned on. The capacitor Ca is a large-capacity capacitance element, and its function is the same as in the embodiment of FIG. The functions of the current limiting circuit 82, the drive control circuit 83, and the braking circuit 84 are the same as those in the embodiment of FIG.

  Further, when the main control board 50 and the medal payout control board 55 are connected by two wires, it is not always necessary to provide the energizing transistor Qb and the control transistor Qc for energizing and controlling DC24V. As shown, it is also preferable to control the rotation of the dispensing motor MO only by the energizing transistor Qb for energizing the ground line.
