Abstract

An electrophotographic printing machine frequently employs a drum having a replenishable photoreceptor, The photoreceptor drum employs a take-up spool 18 and a take-up gear 62 mounted on one end of the support shaft thereof. Take-up gear 62 meshes with drive gear 64. Rotation of drive gear 64 in the direction of arrow 68. Rotation of gear 62 in the direction of arrow 68 rotates take-up spool 18 also in the direction of arrow 68 so as to advance the used portion of photoconductive belt 14 thereon and to advance the unused portion of photocon-ductive belt 14 from supply spool 16 about the exterior surface of drum 10, Arm 70 is connected to gear 64. Rotation

A PHOTOCONDUCTOR INCREMENTING APPARATUS (Cont~d)

of arm 70 in the direction of arrow 72 rotates gear 64 in the
direction of arrow 66 As drum 10 rotates in the direction of
arrow 12, arm 70 contacts shaft 74 of solenoid 76~ Shaft 74 of
solenoid 76 extends into contact with arm 70 only upon being
energized.~ When solenoid 76 is de~energized, shaft 74 is
retracted and will no longer engage arm 70~ Thus, shaft 74 is
adapted to reciprocate in the direction of arrow 78~

In operation, drum 10 rotates in the direction of arrow 12
causing arm 70 to engage shaft 74 of solenoid 76~ When arm 70
engages shaf...
