Sheet paper feeding apparatus

Abstract

Abstract PURPOSE: To prevent a sheet paper from soiling and wrinkling by making a reverse roller follow the motion of a load when a load torque higher than the fixed value is applied, in case of a feeding apparatus having a mechanism for preventing double-feed. CONSTITUTION: When a sheet 11 is applied, a solenoid 10 operates to press a regular rotation roller 1 to a reverse roller 2. In the case that one sheet 11 is fed, it advances by the regular rotation roller 1. Because the driving force of this roller is large, a friction clutch 3 slips and the reverse roller 2 follows the motion of a sheet. In the case that two sheets are fed, they slips from each other, since the coefficient of friction between the sheets is small, and the upper sheet 11a advances and the lower sheet 11b is stopped by the reverse roller 2. In this way, any soiling and wrinkling of the sheet due to slippery contact with the reverse roller is prevented from generating. COPYRIGHT: (C)1982,JPO&Japio
