[Details of movable member moving mechanism]
The movable member moving mechanism 19 a 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. 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 performance 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.

Specifically, the driver IC 41 is a driver IC for bipolar driving 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 stepping motor 30 is driven and controlled by outputting while switching.

By the way, when a game machine is manufactured, 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 manufacture, it is inspected whether the motor can properly move the movable member even if a current smaller than that during the game is input to the motor. 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 the performance control board is directly applied to the voltage reference terminal of the driver IC as a reference voltage. For this reason, in the inspection at the time of manufacture, it is necessary to prepare a special inspection jig capable of generating a desired magnitude of reference voltage in place of the performance control board.

On the other hand, the game machine 1 can input the reference signal output from the performance control board 200 or the inspection jig, and the reference voltage generation circuit 42 that applies the 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 be able to generate two or more different reference voltages based on the reference signal. Therefore, the game machine 1 does not need to prepare a special jig for inspection, and can be inspected using the built-in reference voltage generation circuit 42 as it is, which is excellent from the viewpoint of inspection efficiency. The reference voltage generation circuit 42 that generates the reference voltage to be applied to the driver IC 41 will be described in detail below.

The first transistor Tr1 and the second transistor Tr2 are configured such that their drive states can be switched based on the output signal from the logic element. Specifically, when 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 When the output signal to the second transistor Tr2 becomes L level, the second transistor Tr2 is controlled to be 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, whereby 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 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.

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 Tr1 whose drive state can be switched based on the output signal from the logic element. Tr2, two different reference voltages can be generated according to the drive state of these transistors. Specifically, when the 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 the voltage V of the constant-voltage power supply and the voltage V of the first wiring 51. determined by the resistance R1 and the resistance R of the third wiring 53 (Vref1=V.times.R1/(R1+R)). is determined by the voltage V of the constant voltage source, the resistance R2 of the second wiring 52 and the resistance R of the third wiring 53 (Vref2=V.times.R2/(R2+R)). When an H level is input as the reference signal EXT1 during a game and an L level is input as the reference signal EXT1 during a test, for example, the resistors R1, R2 and R2 are connected so that Vref2=0.8×Vref1. A resistance value of R may be 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 the 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 can generate two types of output signals from one system of reference signal. A reference voltage can be generated. Since the gaming machine 1 is configured to provide a logic element capable of inputting a reference signal to the reference voltage generation circuit 42, it is possible to improve the degree of freedom in designing the reference voltage generation circuit 42 compared to the case where no logic element is used. . Moreover, the reference voltage generation circuit 42 is particularly remarkable in that it can generate two different reference voltages even if the reference signal to the reference voltage generation circuit 42 is only one system.

The third transistor Tr3 is also configured to be able to switch its drive state based on the output signal from the logic element. Specifically, when H level is input as the reference signal EXTφ, the output signal from the logic element to the third transistor Tr3 becomes L level, thereby turning off the third transistor Tr3. On the other hand, when L level is input as the reference signal EXTφ, the output signal from the logic element to the third transistor Tr3 becomes H level, whereby 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 reference signal EXTφ to be input.

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 65 to the voltage reference terminal 41a is determined by the voltage V of the constant voltage source, 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. be.

As described above, the reference voltage generation circuit 43 has logic elements capable of receiving two systems of reference signals, 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 to the reference voltage generation circuit 43 is provided, it is possible to improve the degree of freedom in designing the reference voltage generation circuit 43 compared to the case where no logic element is used. . Moreover, 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 that the driver IC 41 outputs to the stepping motor 30 can be variously adjusted.
