ROTARY DRUM STRUCTURE FOR PICTURE PRODUCING MACHINE

摘要

PURPOSE:To sufficiently eliminate the possibility of occurring insufficient grounding of a photosensitive body by grounding the photosensitive body in such a way that electrode pieces are pressed against the peripheral surface of a drum supporting shaft while the electrode pieces are elastically deviated inward in the radial direction and grounding the photosensitive drum through the drum supporting shaft and electrode pieces. CONSTITUTION:Compression coil springs 120 and 122 constituting an elastically deviated means which acts on electrode pieces 106 and 108 elastically deviate the pieces 106 and 108 upward. The pieces 106 and 108 partially protrude upward through openings 102 and 104 and connecting terminal lines 124 and 126 are fixed to the pieces 106 and 108. The connecting terminal lines 124 and 126 extended outward through an opening 128 formed on the side wall of a box body 96 are connected to the power source circuit of a picture producing machine through suitable connecting lines. Therefore, the photosensitive body is grounded by utilizing the electrode pieces pressed against the supporting shaft of the photosensitive body and the possibility of occurring insufficient grounding can be eliminated to substantially zero or can be reduced to an extremely lower level.
