Abstract

PURPOSE: To reduce the damage of a photoreceptor by reducing impact force during contact by bringing a breaking-away pawl into contact with the photoreceptor only at need and then by breaking a form away by increasing the contact pressure by steps.
CONSTITUTION: Tip 2a of breaking-away pawl 2 provided around fixed shaft 3 in an oscillatory state is in contact with photoreceptor 1 by its own weight. Between both sides of fixed shaft 3 as a boundary, weight W2 of read-end part 22 is greater than weight W1 of tip-side part 21 and the contact is made with contact pressure P1 of weight (W2-W1). Right before form A carried in contact with photoreceptor 1 reaches breaking-away pawl tip 2a. electric signal R1 is sent to solenoid 8 to separate L-shaped lever 13 supporting weighting member 5, and consequently oscillatory arm 4 is lowered to apply breaking-away pawl 2 with weight W3 of curved piece 6. As a result, the contact pressure of pawl 2 to photoreceptor 1 is P2 by weight (W2-W1)+W3. Thus, the contact pressure to pawl 2 increases by steps, so that impact force in contact can be reduced.
