2. Description of the Related Art In a pachinko game machine, as is well known, a CP is used.
A game control circuit board composed of U, RAM, ROM, etc. is provided. The game board is provided with various forms of variable winning devices which are opened and closed by a solenoid, a motor, etc., and a lamp which blinks at the time of a big hit. Electrical loads such as solenoids, motors, lamps, and the like are configured to operate by switching elements such as power transistors provided on the game control circuit board opening and closing based on instructions from the CPU.

[0003] Meanwhile, since the game board surface is very complicated, an unexpected external force is applied to the electric load of the solenoid, the motor, the lamp, and the like, or a trouble such as a short circuit of a lead wire is easily caused. Therefore, when an overcurrent flows, a switching element such as a power transistor may be broken. Therefore, conventionally, a fuse has been provided in series with the electric load so that overcurrent is cut off by fusing.
