With this circuit configuration, when the rotation of the motor 52 is slow and positive, no load current flows through the motor 52 and no brake is applied. However, when the rotation speed exceeds a certain number of rotations, the load current flows and the number of rotations of the motor 52 is constant.

  (Embodiment 2)

  FIG. 6 is a diagram illustrating a circuit configuration of the flow rate adjusting device 60 of the pachinko machine 1 according to the second embodiment. The front side configuration and the back side configuration of the pachinko machine 1 according to the second embodiment are the same as those shown in FIGS. 1 and 2 of the first embodiment, and therefore illustration and description of the configuration are omitted. . Further, since the mechanical configuration of the flow speed adjusting device 60 is the same as that shown in FIG. 3 of the first embodiment, the illustration and configuration description thereof are omitted. In the circuit configuration shown in FIG. 6, the same components as those in the circuit configuration shown in FIG.

  In FIG. 6, a flow-down speed adjusting device 60 includes a motor 52, a Zener diode 53, a comparator 61, voltage dividing resistors 62a to 62c, a reference voltage source 63b, a microcomputer 64, and a motor driving transistor TR1. I have.

  The comparator 61 inputs the detection voltage VM obtained by dividing the power generation voltage of the motor 52 by the voltage dividing resistors 62a and 62b to the non-inverting input terminal (+), and inputs the reference voltage VS of the reference voltage source 63b to the inverting input terminal (−). The detection voltage VM and the reference voltage VS are compared, and the comparison result (“Hi” signal or “Low” signal) is output to the microcomputer 64. The comparator 61 outputs a “Hi” signal as a comparison result when the detection voltage VM is higher than the reference voltage VS, and outputs a “Low” signal as a comparison result when the detection voltage VM is lower than the reference voltage VS.

  The voltage dividing resistors 62a and 62b have resistance values set in consideration of the power generation voltage range and internal resistance of the motor 52 and the input voltage range of the comparator 61 so that the detection voltage VM input to the comparator 61 does not become excessive. To do. The reference voltage source 63b sets a DC voltage value serving as a threshold value that makes it possible to determine whether the motor 52 is rotating based on the detection voltage VM.

  The microcomputer 64 is mounted on the discharge control device 46 described above, and executes a ball clogging detection process (described later) for determining whether or not the ball in the ball passage 41d is based on the comparison result output from the comparator 61. In the ball clogging detection process, the microcomputer 64 determines whether or not the sprocket roller 51 is rotating based on whether the comparison result from the comparator 61 is a “Hi” signal or a “Low” signal, and determines that there is a ball clogging. A notification operation and a forced ball flow down operation are performed.

  Next, the operation of the second embodiment will be described.

  A ball clogging detection process executed by the microcomputer 64 every predetermined period (for example, 10 minutes) will be described with reference to FIG. FIG. 7 is a flowchart showing a ball clogging detection process executed by the microcomputer 64. This ball clogging detection process is executed at a predetermined interrupt timing with respect to the game control process executed by the game control device 42 described above. The microcomputer 64 has a timer (not shown) that sets a monitoring time for monitoring the rotation stop time of the sprocket roller 51.

  In step S101, the microcomputer 64 determines whether or not the sprocket roller 51 has stopped rotating for a predetermined time according to the setting of the timer. In this case, the criterion is that the set time of the timer is up. If it is determined that the sprocket / roller 51 has stopped rotating for a predetermined time, the process proceeds to step S102. If it is determined that the sprocket / roller 51 is not rotating (the sprocket / roller 51 is rotating), it is determined that there is no clogging. The clogging detection process ends.

  In step S102, a signal for rotating the motor 52 forward is output, and the process proceeds to step S103.

  In step S103, the above timer is used to monitor again whether or not the sprocket roller 51 has stopped rotating for a predetermined time. If the “Hi” signal, that is, a signal indicating that the sprocket roller 61 is rotating is received from the comparator 61 a predetermined number of times (for example, once) before the timer expires, If not, the clogging detection process is terminated. If the "Hi" signal from the comparator 61, that is, a signal indicating that the sprocket roller 61 is rotating is not received a predetermined number of times (for example, once) before the timer expires, It is determined that clogging has occurred, and the process proceeds to step S104.

  In step S104, it is determined that a ball clogging has occurred due to the rotation stop determination in steps S101 to S103 described above, and a ball clogging error notification operation is executed. At this time, the microcomputer 64 sends a ball clogging error notification signal to a hall management system (not shown) to notify the store clerk that a ball clogging has occurred in the pachinko machine 1. In addition, a ball clogging error lamp (not shown) provided on the front surface of the pachinko machine is turned on.

  In step S105, it is determined whether or not a release button for canceling the error notification described above has been pressed. In this case, it is assumed that the error release button is installed, for example, at the mounting place of the discharge control device 46 on the back side shown in FIG. When the clogging is physically resolved by the clerk who confirmed the error notification described above and the error release button is pressed, the microcomputer 46 detects that the error release button has been pressed, cancels the error notification operation, The ball clogging detection process ends. Further, the error notification operation is continued until the pressing of the error release button is detected.

  FIG. 8 is an external perspective view of the game ball induction coil 70 used in the flow speed adjusting device of the pachinko machine 1 according to the third embodiment. The front side configuration and the back side configuration of the pachinko machine 1 according to the third embodiment are the same as those shown in FIGS. 1 and 2 of the first embodiment, and the illustration and description of the configuration are omitted. . The game ball induction coil 70 of FIG. 8 is installed in the above-described ball passage 41d, and has a substantially U-shaped core material (magnetic material) 71 having a gap through which the flowing game ball 100 can pass, and this core material. 71, and a coil 72 wound around an arm portion 71a.

  The game ball induction coil 70 connects both terminal portions of the coil 72 to a flow rate adjusting device 80 described later, and generates an AC magnetic field in the gap of the core material 71 by an AC drive signal supplied to the coil 72 by the flow rate adjusting device 80. Then, a change in inductance generated according to the passing speed when the game ball 100 passes through the gap is output to the flow-down speed adjusting device 80 as a coil current signal.

  FIG. 9 is a diagram illustrating a circuit configuration of the flow rate adjusting device 80 according to the third embodiment. The flow-down speed adjusting device 80 includes a power supply circuit 81, a variable output oscillation circuit 82, AC drive output transistors TR1 and TR2, a DC blocking capacitor C, the above-described game ball induction coil 70, and a current detection resistor R. A detection circuit 83, a low-pass filter 84, a differentiation circuit 85, and a voltage comparison circuit 86.

  The power supply circuit 81 includes a DC power supply, and supplies the DC power to each part in the flow-down speed adjusting device 80.

  The variable output oscillating circuit 82 oscillates based on the gaming ball falling speed detection signal (oscillation amplitude switching signal) output from the voltage comparison circuit 86 and outputs the oscillation signal (high frequency current) to the AC drive output transistors TR1, It supplies to each base electrode of TR2.

  The AC drive output transistors TR1 and TR2 amplify the oscillation signal supplied from the variable output oscillation circuit 82, and supply the AC drive signal from the common connection point to the game ball induction coil 70 through the DC blocking capacitor C.

  The game ball induction coil 70 in the figure shows the equivalent circuit of FIG. 8, and the AC drive signal supplied from the AC drive output transistors TR1 and TR2 flows through the induction coil 72, thereby causing the gap in the core material 71 described above. Generates an alternating induction magnetic field. The game ball induction coil 70 outputs a change in inductance that occurs when the game ball 100 falls through the gap to the current detection resistor R as a coil current.

  The current detection resistor R outputs an AC voltage signal corresponding to a change in the coil current output from the game ball induction coil 70 to the detection circuit 83.

  The detection circuit 83 includes a diode D and a resistor r 1, detects a positive (+) side voltage signal of an AC voltage signal output from the current detection resistor R, and outputs the detection signal to the low-pass filter 84.

  The low-pass filter 84 includes a resistor r2 and a capacitor c1, and extracts a low-frequency signal having a cutoff frequency or lower from the detection signal output from the detection circuit 83, thereby generating a continuous envelope signal from the detection signal and a differentiation circuit. Output to 85.

  The differentiation circuit 85 includes an operational amplifier OP1, a capacitor c2, and a resistor r3. The differentiation circuit 85 differentiates the envelope signal output from the low-pass filter 84, generates a phase inversion signal obtained by inverting the phase of the differentiation signal, and inverts the voltage comparison circuit 86. Output to the input terminal (-).

  The voltage comparison circuit 86 includes an operational amplifier OP2 and a reference power supply P, compares the voltage level of the phase inversion signal output from the differentiation circuit 85 with the reference voltage VS, and uses the comparison result as a game ball falling speed detection signal as a variable output oscillation. Output to the circuit 82. Specifically, when the voltage level of the phase inversion signal is greater than the value of the reference voltage VS (when the rate of change per time is greater than a specific value), the voltage comparison circuit 86 has a predetermined flow velocity of the game ball 100. And the game ball falling velocity detection signal for enhancing the alternating magnetic field of the game ball induction coil 70 is output to the variable output oscillation circuit 82.

  Next, the operation of the third embodiment will be described.

  First, when the game ball 100 passes through the gap of the core material 71 of the game ball induction coil 70, the change in coil current accompanying the inductance change generated in the game ball induction coil 70 according to the passing speed is shown in FIG. This will be described with reference to FIG.

  FIG. 10 is a diagram showing a change in coil current when the flow speed of the game ball 100 is slow. FIG. 11 is a diagram illustrating a change in coil current when the flow speed of the game ball 100 is high. In each figure, the vertical axis represents the coil current I [A], and the horizontal axis represents the time T [s]. Also, the alternate long and short dash line in each figure indicates the center position of the gap through which the game ball 100 passes.

  In each figure, when the game ball 100 passes through the gap, the first half period T1, T3 and the second half period T2, T4 are detected in order to detect the amplitude change in the time axis direction of the coil current I with reference to the gap center position. It shows the case of setting. The first half periods T1 and T3 indicate periods when the game ball 100 approaches the gap center position, that is, until the game ball 100 reaches the gap center position. The latter half periods T2 and T4 indicate periods when the game ball 100 leaves the gap center position.

  When the game ball 100 passes through the gap, the inductance of the game ball induction coil 70 gradually increases and the coil current I decreases in the first half period T1, T3, and the inductance of the game ball induction coil 70 in the second half period T2, T4. Gradually decreases and the coil current I increases. Further, since the second half periods T2 and T4 are longer than the first half periods T1 and T3 (T2> T1, T4> T3), when the game ball 100 passes through the gap, the second half periods T2 and T4 are affected by the AC magnetic field. It can be seen that the flow speed decreases at T2 and T4. Such a change tendency of the coil current I is a phenomenon that occurs regardless of the flow speed of the game ball 100.

  In the flow-down speed adjusting device 80 according to the third embodiment, the amplitude change in the time axis direction of the coil current I output from the game ball induction coil 70 is a period based on the gap center position (the first half period T1, T3 or the second half period). When the voltage comparison circuit 86 compares with the reference voltage VS every T2, T4), and the voltage level of the phase inversion signal is larger than the value of the reference voltage VS, the flow-down speed of the game ball 100 exceeds a predetermined speed. judge. The voltage comparison circuit 86 adjusts the amplitude of the AC drive signal so as to increase the AC magnetic field generated by the game ball induction coil 70 when it is determined that the flow-down speed of the game ball 100 exceeds a predetermined speed. Therefore, in the voltage comparison circuit 86, in order to determine whether the amplitude change rate per hour of the coil current I exceeds a specific threshold value (reference voltage VS), the reference power supply P that generates the reference voltage VS is used. It is connected to the non-inverting input terminal (+).

  The example of FIG. 10 shows a case where the rate of change in amplitude per time of the coil current I is lower than the reference voltage in both the periods T1 and T2, and the flow rate of the game ball 100 is low. In the example of FIG. 11, both the periods T3 and T4 show a case where the rate of change in the amplitude of the coil current per time is higher than the reference voltage VS, and the flow speed of the game ball 100 is higher than a predetermined speed. .

  Next, a specific example in which the flow speed adjusting device 80 adjusts the flow speed of the game ball 100 will be described with reference to FIG. FIG. 12 is a diagram showing a change in the coil current I when the flow velocity of the game ball 100 is faster than a predetermined velocity and the alternating magnetic field generated by the flow velocity adjusting device 80 in the game ball induction coil 70 is strengthened.

  Before the game is started, in the flow-down speed adjusting device 80, the variable output oscillation circuit 82 supplies the oscillation signal having the reference amplitude to the AC drive output transistors TR1 and TR2, and the reference amplitude is output from the AC drive output transistors TR1 and TR2. An AC drive signal is supplied to the game ball induction coil 70 to generate an AC magnetic field in the gap of the core material 71 in the game ball induction coil 70.

  Then, when the game is started by the player and the game ball 100 starts to flow down in the ball passage 41d, the inductance changes when the game ball 100 passes through the gap of the core material 71, so that the amplitude of the coil current I is timed. It changes in the axial direction. The changing state of the coil current I is shown in FIG. In the example of this figure, the first half period T5 in which the amplitude change of the coil current I appears is shorter than the first half period T1 shown in FIG. 10 (T5 <T1). It is assumed that the amplitude of the coil current I in the first half period T5 is A1.

  In the falling speed adjusting device 80, the coil current I output from the game ball induction coil 70 becomes an AC voltage signal by the current detection resistor R, becomes a detection signal consisting of a positive (+) side voltage signal by the detection circuit 83, and the low-pass filter 84. Becomes an envelope signal, and the differentiation circuit 85 becomes a phase inversion signal. The change in the amplitude of the coil current I in the time axis direction is converted into an envelope signal by the low-pass filter 84, so that the voltage level continuously changes with time. In addition, the envelope signal is differentiated by the differentiation circuit 85 and converted into a phase inversion signal, whereby a change region of the envelope signal is extracted.

  In the case of FIG. 12, since the rate of change in amplitude per time of the coil current I in the first half period T5 is large, the change in the falling region (change in voltage level) included in the phase inversion signal output from the differentiating circuit 85 also becomes large. .

  Then, the voltage comparison circuit 86 compares the voltage level of the phase inversion signal output from the differentiation circuit 85 with the reference voltage VS. Since the voltage level of the phase inversion signal exceeds the reference voltage VS (threshold value), the voltage comparison circuit 86 determines that the flow speed of the game ball 100 exceeds a predetermined speed and sets the oscillation amplitude to a large value. A speed detection signal (oscillation amplitude switching signal) is output to the variable output oscillation circuit 82. The variable output oscillation circuit 82 generates an oscillation signal having a large oscillation amplitude based on a game ball falling speed detection signal (oscillation amplitude switching signal) output from the voltage comparison circuit 86 as a base electrode of each of the AC drive output transistors TR1 and TR2. To supply.

  The AC drive output transistors TR1 and TR2 supply the game ball induction coil 70 with an AC drive signal corresponding to the oscillation signal supplied from the variable output oscillation circuit 82. Thereafter, the alternating magnetic field generated in the gap of the core material 71 of the game ball induction coil 70 is strengthened, and the flow-down speed of the game ball 100 is reduced. As a result, as shown in the second half period T6 in FIG. 12, the amplitude A2 of the coil current I output from the game ball induction coil 70 is larger than the amplitude A1 of the first half period T5 (A2> A1). The rate of change in amplitude also becomes moderate.

  The period T7 shown in the figure is a period in which the flow speed adjusting device 80 determines that the flow speed of the game ball 100 exceeds a predetermined speed and performs control to increase the AC magnetic field of the game ball induction coil 70. It shows that there is.

  Note that the flow rate adjusting device 60 shown in FIG. 6 of the second embodiment may have the circuit configuration shown in FIG. This flow-down speed adjusting device 60 deletes the voltage dividing resistor 62c for forcibly driving the motor 52 and the motor driving transistor TR1 from the flow-down speed adjusting device 60 shown in FIG. Is to do.

  Further, in the gaming ball induction coil 70 shown in FIG. 8 of the third embodiment, the positional relationship with the ball passage through which the ball flows down is not specifically shown, but the core material 71 and the ball of the gaming ball induction coil 70 are not shown. Specific examples of the positional relationship with the passage are shown in FIGS.

  14 and 15 are diagrams showing an example of the positional relationship between the cross section of the ball passage 41 through which the ball 100 flows down and the core material 71 of the game ball induction coil 70. FIG. In this case, the thickness of the wall 41z of the spherical passage 41 located near the core material 71 is characterized by being thicker than the thickness of the wall 41y of the spherical passage 41 located far from the core material 71. Thus, only the wall 41z where the ball 100 is likely to collide may be thickened in consideration of the direction of the magnetic flux generated by the game ball induction coil 70.

  Note that the game control device 43 shown in FIG. 2 of the first embodiment includes a CPU, a ROM, a RAM, an I / O, and the like, and is electrically connected to a sensor of each winning opening. 2 includes a CPU, a ROM, a RAM, an I / O, and the like, and is connected to a sensor (not shown) that detects a game ball flowing down the ball passage 41d. Based on a signal instructing the discharge of the number of gaming balls corresponding to the winning winning port from the gaming control device 43 that has received a signal from the sensor that has detected that a gaming ball has won the winning winning port, the discharging device 40 is controlled. It is configured to control.

You may make it apply to CPU, ROM, RAM, and I / O which were provided in the apparatus 43 and the discharge | emission control apparatus 46. FIG.

  The ball clogging detection process in FIG. 7 is executed at regular intervals in the second embodiment, but is executed on condition that the discharge control device 46 starts the discharge operation of the discharge device 40. Alternatively, it may be executed after a predetermined time (for example, 1 second) has elapsed since the discharge control device 46 causes the discharge device 40 to start the discharge operation. That is, the start condition / timing of the ball clogging detection process may be set as appropriate.

  Further, the present invention may be applied to a game island facility, a pachislot machine, and a parrot such as a game medium transport unit having a transport path for transporting game media such as medals and balls other than pachinko machines. For example, you may make it apply this invention to the circulation path of the game island which circulates the game ball collect | recovered from the pachinko machine etc. again to a pachinko machine.

  As mentioned above, although the Example of this invention was described, it has only illustrated the specific example and does not specifically limit this invention. That is, the present invention detects a ball path for flowing a game ball and a flow speed of the game ball flowing down the ball path, and adjusts the speed to reduce the flow speed of the game ball when the flow speed exceeds a predetermined speed. The specific configuration of the means such as the ball passage and the speed adjusting means can be appropriately changed in design.
