Title:
ELECTRONIC BOARD FOR PACHINKO MACHINE
Document Type and Number:
Japanese Patent JP3896551
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make circuit design easier and to realize high voltage prevention with a reduced cost, by discharging an electrified charge to an earth line after temporarily storied, and eliminating high voltage applied by static electricity on the input terminal on a control circuit board.
SOLUTION: A extending part 6 extending out in a narrow width toward a part of a printed pattern 5 on an earth line is mounted on a printed pattern 4 on the input end, and a high voltage protective means comprising a gap 7 on an insulation part in a microwidth is mounted on the approaching part between the extending part 6 of the printed pattern on the input end and the printed pattern 5 of the earth line. When charge of static electricity is stored in the printed pattern 4 on the input end of a control circuit board, the voltage at the printed pattern 4 on the input end goes up toward a high voltage. Thus, positive charge stored on the printed pattern 4 is naturally discharged jumping from the extended part 6 over the gap 7 toward the printed pattern 5 to removed the high voltage applied on the printed pattern is eliminated.
