[Details of movable member moving mechanism]
The movable member moving mechanism 19a is a mechanism that controls the movement of the movable member 19 based on a control signal from the effect control board 200. 4 to 7 show four examples of the circuit configuration of the movable member moving mechanism 19a, respectively. First, an example of the circuit configuration of the movable member moving mechanism 19a will be described with reference to FIG. 4, and then another example of the circuit configuration of the movable member moving mechanism 19a will be described with reference to FIGS.

  The movable member moving mechanism 19a includes a stepping motor 30, and a motor control board 40 connected to the stepping motor 30, as shown in FIG. The movable member moving mechanism 19a inputs a control signal from the effect control board 200 to the motor control board 40, operates the stepping motor 30 by drive control of the motor control board 40, and moves the movable member 19 by the operation of the stepping motor 30.

The stepping motor 30 is connected to four current terminals 41b of the driver IC 41, which will be described later, inputs a current output from one or two current terminals 41b to the stator 30a, and inputs three to four currents to the stator 30b.

More specifically, the driver IC 41 is a driver IC that bipolar-drives the stepping motor 30, and has a voltage reference terminal 41a for applying a reference voltage and four current terminals 41b for outputting a constant current. The magnitude of the constant current to be output is determined according to the magnitude of the reference voltage applied to the reference terminal 41a, and the constant current is output from the four current terminals 41b based on the two-phase excitation sequence or the 1-2-phase excitation sequence. By controlling the output of the stepping motor 30, the driving of the stepping motor 30 is controlled.

  By the way, at the time of manufacturing a gaming machine, it is inspected whether or not the manufactured movable member moving mechanism can appropriately move the movable member. Specifically, in the inspection at the time of manufacturing, it is inspected whether the motor can appropriately move the movable member even if a smaller current is input to the motor than during the game. In order to input a small current to the motor, it is necessary to reduce the reference voltage applied to the voltage reference terminal of the driver IC. In a normal gaming machine, a reference signal (H level or L level) from an effect control board is directly applied as a reference voltage to a voltage reference terminal of a driver IC. For this reason, in the inspection at the time of manufacturing, it is necessary to prepare a special inspection jig capable of generating a reference voltage of a desired magnitude in place of the effect control board.

  On the other hand, the gaming machine 1 can input a reference signal output from the effect control board 200 or the inspection jig, and applies a reference voltage generated based on the reference signal to the voltage reference terminal 41a. It has. The reference voltage generation circuit 42 is configured to generate two or more different reference voltages based on the reference signal. For this reason, the gaming machine 1 does not need to prepare a special inspection jig, and can perform the inspection using the built-in reference voltage generation circuit 42 as it is, which is excellent in terms of inspection efficiency. Hereinafter, the reference voltage generation circuit 42 that generates the reference voltage applied to the driver IC 41 will be described in detail.

(Reference voltage generation circuit)
The reference voltage generation circuit 42 has a logic element (two NOT gates 50a) to which the reference signal EXT1 can be input, as shown in FIG. Further, the reference voltage generation circuit 42 includes a first wiring 51 having a first transistor Tr1, a second wiring 52 provided in parallel with the first wiring 51 and having a second transistor Tr2, A third wiring 53 connected between the junction of the first wiring 51 and the second wiring 52 and the constant voltage power supply (+ V), and a third wiring 53 connected between the junction and the voltage reference terminal 41a. 4 wirings 54. Note that the first wiring 51 has a resistance R1, the second wiring 52 has a resistance R2, the third wiring 53 has a resistance R, and the first wiring 51 and the second wiring 52, the ends opposite to the junction are connected to the ground. The resistances of the resistors R1 and R2 are different from each other. Further, a bipolar transistor or a field effect transistor (MOSFET) is used as the transistor.

  The driving state of the first transistor Tr1 and the second transistor Tr2 can be switched based on an output signal from a logic element. Specifically, when the H level is input as the reference signal EXT1, the output signal from the logic element to the first transistor Tr1 becomes H level, whereby the first transistor Tr1 is controlled to be ON, and the logic element outputs When the output signal to the second transistor Tr2 becomes L level, the second transistor Tr2 is controlled to be turned off. On the other hand, when the L level is input as the reference signal EXT1, the output signal from the logic element to the first transistor Tr1 becomes L level, so that the first transistor Tr1 is controlled to be OFF, and the logic element outputs the second transistor Tr1. When the output signal to the transistor Tr2 becomes H level, the second transistor Tr2 is controlled to be ON. That is, the reference voltage generation circuit 42 can drive one of the first transistor Tr1 and the second transistor Tr2 according to the type (H level or L level) of the input reference signal EXT1.

  The reference voltage generation circuit 42 includes a logic element (two NOT gates 50a) to which the reference signal EXT1 can be input, and a first transistor Tr1 and a second transistor that can switch the driving state based on an output signal from the logic element. Tr2, two different reference voltages can be generated in accordance with the driving states of these transistors. Specifically, when an H level is input as the reference signal EXT1, the reference voltage applied from the fourth wiring 54 to the voltage reference terminal 41a is equal to the voltage V of the constant voltage power supply, Determined by the resistance R1 and the resistance R of the third wiring 53 (Vref1 = V × R1 / (R1 + R)), and when the L level is input as the reference signal EXT1, the voltage reference terminal 41a from the fourth wiring 54. Is determined by the voltage V of the constant voltage power supply, the resistance R2 of the second wiring 52, and the resistance R of the third wiring 53 (Vref2 = V × R2 / (R2 + R)). When the H level is input as the reference signal EXT1 during the game and the L level is input as the reference signal EXT1 during the test, for example, the resistors R1, R2, and R2 are set so that Vref2 = 0.8 × Vref1. It is preferable that the resistance values of R are set respectively.

  As described above, the reference voltage generation circuit 42 has a logic element to which a reference signal can be input, and can generate two different reference voltages based on an output signal from the logic element. Since the logic element can generate two types of output signals (H level and L level) from one system of reference signal (H level or L level), the reference voltage generation circuit 42 generates two types of output signals from one system of reference signal. A reference voltage can be generated. Since the gaming machine 1 has a configuration in which a logic element capable of inputting a reference signal is provided in the reference voltage generation circuit 42, the degree of freedom in designing the reference voltage generation circuit 42 can be improved as compared with a case where the logic element is not used. . Further, the reference voltage generation circuit 42 is particularly remarkable in that two types of different reference voltages can be generated even when the reference signal to the reference voltage generation circuit 42 is only one system.

Note that the first wiring 61 has a resistance R1, the second wiring 62 has a resistance R2, the third wiring 63 has a resistance R3, and the fourth wiring 64 has a resistance R. The ends of the first wiring 61, the second wiring 62, and the third wiring 63 on the side opposite to the junction are connected to the ground. The resistances of the resistors R1, R2, and R3 are different from each other.

  The driving state of the first transistor Tr1 and the second transistor Tr2 can be switched based on an output signal from a logic element. Specifically, when the H level is input as the reference signal EXT1, the output signal from the logic element to the first transistor Tr1 becomes H level, whereby the first transistor Tr1 is controlled to be ON, and the logic element outputs When the output signal to the second transistor Tr2 becomes L level, the second transistor Tr2 is controlled to be turned off. On the other hand, when the L level is input as the reference signal EXT1, the output signal from the logic element to the first transistor Tr1 becomes L level, so that the first transistor Tr1 is controlled to be OFF, and the logic element outputs the second transistor Tr1. When the output signal to the transistor Tr2 becomes H level, the second transistor Tr2 is controlled to be ON. That is, the reference voltage generation circuit 43 can drive either the first transistor Tr1 or the second transistor Tr2 according to the type (H level or L level) of the input reference signal EXT1.

  Further, the third transistor Tr3 is also configured to be able to switch the driving state based on an output signal from the logic element. Specifically, when an H level is input as the reference signal EXTφ, the output signal from the logic element to the third transistor Tr3 becomes L level, so that the third transistor Tr3 is controlled to be OFF. On the other hand, when the L level is input as the reference signal EXTφ, the output signal from the logic element to the third transistor Tr3 becomes H level, so that the third transistor Tr3 is controlled to be ON. That is, the reference voltage generation circuit 43 can switch the driving state of the third transistor Tr3 according to the type (H level or L level) of the input reference signal EXTφ.

  The reference voltage generation circuit 43 includes a logic element (three NOT gates 50a) to which the reference signal EXT1 and the reference signal EXTφ can be input, and a first transistor Tr1 that can switch the driving state based on an output signal from the logic element. Since the transistor includes the second transistor Tr2 and the third transistor Tr3, four different reference voltages can be generated in accordance with the driving states of these transistors. Specifically, when the H level is input as the reference signal EXT1 and the H level is input as the reference signal EXTφ, the reference voltage applied to the voltage reference terminal 41a from the fifth wiring 65 is set to the constant voltage power supply. Is determined by the voltage V, the resistance R1 of the first wiring 61, and the resistance R of the fourth wiring 64. When the H level is input as the reference signal EXT1 and the L level is input as the reference signal EXTφ, The reference voltage applied to the voltage reference terminal 41a from the fifth wiring 65 is the voltage V of the constant voltage power supply, the resistance R1 of the first wiring 61, the resistance R3 of the third wiring 63, and the resistance R of the fourth wiring 64. Is determined by When the L level is input as the reference signal EXT1 and the H level is input as the reference signal EXTφ, the reference voltage applied from the fifth wiring 65 to the voltage reference terminal 41a is equal to the voltage V of the constant voltage power supply. Is determined by the resistance R2 of the second wiring 62 and the resistance R of the fourth wiring 64. When the L level is input as the reference signal EXT1 and the L level is input as the reference signal EXTφ, the fifth wiring The reference voltage applied from 65 to the voltage reference terminal 41a is determined by the voltage V of the constant voltage power supply, the resistance R2 of the second wiring 62, the resistance R3 of the third wiring 63, and the resistance R of the fourth wiring 64. You.

  As described above, the reference voltage generation circuit 43 has the logic elements to which the two systems of reference signals can be input, and can generate four different reference voltages based on the output signals from the logic elements. The logic element can generate four types of output signals from two systems of reference signals. Since the gaming machine 1 has a configuration in which a logic element capable of inputting a reference signal is provided to the reference voltage generation circuit 43, the degree of freedom in designing the reference voltage generation circuit 43 can be improved as compared with a case where the logic element is not used. . Further, since the reference voltage generation circuit 43 can generate four different reference voltages, it is particularly remarkable in that the magnitude of the constant current output from the driver IC 41 to the stepping motor 30 can be variously adjusted.
