[0005]

Since the command voltage setting circuit in the conventional pachinko machine driver device is configured as described above, the following problems exist. That is, in the case of the configuration of FIG. 2 described above, each surge eliminating capacitive element absorbs static electricity, noise, etc. so that static electricity, noise, etc. from the outside will not be included in the command voltage output. However, since the surge eliminating capacitive element is directly connected between the first terminal of the variable resistor, that is, the cathode terminal of the shunt regulator and the ground, the command from the shunt regulator depends on the capacitance of the surge eliminating capacitive element. The voltage output may oscillate, the command voltage output becomes unstable with wavy or fluttering, and the command voltage output at the level corresponding to the rotating position of the steering wheel is not stable, which seriously hinders the pachinko ball firing control. Was coming.

The present invention has been made to solve the above problems, and in particular, eliminates the oscillation phenomenon of the output of a shunt regulator by a surge eliminating capacitive element,
An object of the present invention is to provide a command voltage setting circuit in a driver device for a pachinko machine that stabilizes the command voltage output.
