Title:
PRINTED CIRCUIT BOARD, DEVICE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2017120925
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the area required for a contact part to reduce a force required during assembly, and easily perform visual check of the contact part.SOLUTION: There is provided a printed circuit board 101 on which a circuit generating voltage is mounted, the printed circuit board comprising a slit 104 that penetrates through the printed circuit board 101 and a jumper wire 103 that is provided across the slit 104 and applied with a voltage, when attached to a charging part 317 to which an arm part 202 of a helical torsion coil spring having elasticity is connected, an arm part 203 of the helical torsion coil spring passing through the slit 104 comes into contact with the jumper wire 103, and thereby a voltage is supplied to the charging part 317 via the helical torsion coil spring.SELECTED DRAWING: Figure 2
