PURPOSE:To eliminate restriction of the length of lines by using a constant voltage diode using sufficiently high Zener voltage when driving a magnet for receiving coins, using a sub-constant voltage diode in other conditions thereby charging condensers alternately. CONSTITUTION:The sub-constant voltage diode ZD2 is connected with the constant voltage diode ZD1 in the same direction and in parallel, and Zener voltage of the ZD2 is set lower than Zener voltage of the ZD1, for instance 4V. Accordingly, the constant voltage diode ZD1 goes to off state. At the same time, condensers C2-C6 are charged by Zener voltage of the sub-constant voltage diode ZD2, thereby each power source is supplied. As considerable electric power is required for driving a magnet CM, the sub-constant voltage diode ZD2 is cut off from a DC loop, and loop current is supplied to the constant voltage diode ZD1. Thus, condensers C2-C6 are charged quickly in a short time by the sufficiently high Zener voltage to prevent the occurrence of impediments for receiving coins. |
