[data communication]
Here, data communication from the sub-control circuit 200 to the liquid crystal display device 32 and data communication from the sub-control circuit 200 to the lamp substrates 132a and 132b will be described with reference to FIG.

  The communication of the clock signal and the data signal from the serial interface 222 shown in FIG. 3 to the serial-parallel conversion driver 224 is performed by a serial communication method using a differential signal. Similarly, the clock signal and data signal communication from the serial interface 242 to the serial latch driver 246a and the clock signal and data signal communication from the serial latch driver 246a to the serial latch driver 246b shown in FIG. This is performed by a serial communication system using signals.

  As shown in FIG. 5A, in the data communication of the serial communication system using these differential signals, the signal line 201a to which the differential signal A + is transmitted and the differential signal A + are different in phase by 180 °. This is performed by the common line 201b to which the motion signal A− is transmitted. In FIG. 5A, the left side of the drawing is the upstream side, and the right side of the drawing is the downstream side.

  In the middle of the signal line 201a and the common line 201b, a common mode filter (CMF) 202 for removing common mode noise is provided. Further, on the upstream side of the CMF 202, a varistor (voltage variable resistor) 203a connected to the signal line 201a and a varistor 203b connected to the common line 201b are provided. The varistors 203a and 203b are conventionally known, and when the applied voltage exceeds a threshold value called a varistor voltage, the resistance value rapidly decreases and a large current flows. The varistor voltage is a voltage when a current of 1 mA flows through the varistor. These varistors 203a and 203b have the property of absorbing noise and static electricity and absorb noise that cannot be removed by the CMF 202. In addition, the electrostatic capacity, which is the capacitor component of these varistors 203a and 203b, affects the image signal transmitted at a high speed, and is set to a low capacity of about 1 pF in consideration of this influence.

  As described above, the varistor can be used for serial data communication using differential signals such as data communication from the sub control circuit 200 to the liquid crystal display device 32 and data communication from the sub control circuit 200 to the lamp substrates 132a and 132b. By using 203a and 203b, noise that cannot be removed by the CMF 202 can be absorbed, so that noise resistance in the serial communication system using differential signals is improved. Further, by making the capacitance of the varistors 203a and 203b as low as about 1 pF, the influence on the control signal transmitted at a high speed is sufficiently suppressed.

  The positions where the varistors 203a and 203b are provided are not limited to the upstream side of the CMF 202, and may be the downstream side of the CMF 202, as shown in FIG. 5B, or as shown in FIG. In addition, both the upstream side and the downstream side of the CMF 202 may be used.

  The varistor may be applied to data communication from the main control circuit 60 to the sub control circuit 200 by a serial communication method.

If the jackpot determination random number value is 400, it is determined that the game is a special game that shifts to a probability variation state (special mode). In the case of a specific mode (for example, determined by the value of the status flag (eg, “1”)), the probability of transition to an advantageous game in which a round game advantageous to the player is performed a plurality of times is higher than in the normal mode. . In other words, the probability that it is determined to be out of place is set lower than that in the normal mode, and the probability that it is determined as a special game, a special game, and a special game that shifts to a certain change state (special mode) is higher than that in the normal mode. Each is set high. The same applies to the case of the special mode (for example, determined by the value of the status flag (for example, “2”)).
