<p>PURPOSE:To prevent the occurrence of chattering and to reduce transmission of vibration of a pass sheet guide by constraining movement of a bracket such that a stationary body is formed integrally with a body stay and a pass sheet guide in a way that the pass sheet guide is pressed against the bracket, supporting a reverse roller, by means of an energizing means. CONSTITUTION:Pass sheet guides 7 and 8 are located between a feed roller 4 and a reverse roller 5 rotated forward and reversed by means of a torque limiter. By controlling the torque limiter by means of a friction force responding to the number of sheets 1 guided and conveyed by the guides 7 and 8, the roller 5 is selectively rotated in a reverse direction to prevent the occurrence of a double feed. The pass sheet guide 8 is pressed against a bracket 11, supporting a bearing 10 of a reverse shaft 6 formed integrally with the roller 5 and securely attached to a body stay 13, by means of an energizing means 17 to exert a constraining force on the bracket 11, and transmission of vibration to the pass sheet guide 8 is reduced.</p> |
