ADVANTAGE OF THE INVENTION According to this invention, the fuse which interrupts | blocks the overcurrent to the demand side part with respect to a power supply device can be collected in the part which protruded outside the case cover of the circuit board, and maintenance inspection and replacement | exchange of a fuse can be performed easily. Further, in the present invention, the output unit is an AC output unit for outputting an alternating current, a coarse rectification output unit for outputting a coarse rectification after full-wave rectification, and an output unit for outputting a constant-voltage DC. DC output unit supplies AC power to AC operating components such as a card unit, supplies rough rectified DC to DC operating components such as lamps and electromagnetic solenoids for 24 VDC, and various ICs. A constant voltage of 5 volt DC is supplied to the control element as an operating power supply, and a constant voltage of 12 VDC of DC is supplied to other components such as sensors, motors, and electromagnetic solenoids for 12 VDC. Can be used properly.
Further, in the present invention, if an AC 100 volt detection indicator is disposed on a portion of the circuit board that protrudes outside the case cover, the detection of the AC 100 volt can be appropriately confirmed from outside the power supply device. Further, in the present invention, such that the side where the fuse for interrupting the overcurrent to the demand part connected to the input part, the output part, and the output part is disposed is lower.
If the power supply is mounted on the back of the front frame of the pachinko machine,
There is no inconvenience that the input section, the output section, and the fuse are subject to thermal deterioration due to heat radiation from the power supply device to the outside.
