Abstract

PURPOSE: To eliminate wrong paper feeding and stabilize the paper feeding amount and reduce scattering in registration by detecting the paper feeding roller pressure in a copying machine and allowing a paper feeding roller pressure adjusting apparatus to be operated by the said detected output.
CONSTITUTION: The paper feeding pressure applied to a paper feeding roller 8 is detected by a strain meter 14, and the detection signal is compared with the standard value in a balance circuit. When the pressure is below the standard value, a pulley 18 is turned, and a wire is taken-up, and the pressure applied to the roller 8 is adjusted to the standard value, then a brake 19 is operated and the pulley 18 is held at that position, and the pressure is maintained at the standard value. On the other hand, when the paper feeding pressure is above the standard value, the pulley 18 is turned, and the wire is rolled back, and the pressure is maintained at the standard value. Thus, wrong paper feeding is prevented, and the paper feeding amount can be stabilized, and scattering in registration is reduced.
