<p>PURPOSE:To reduce the number of parts as well as to make the control achievable in an easy manner through control of operation of each copying paper feeding mechanism, by switching a single switch element in shifting a sensitive arm by action of each copying paper in leading passages at two spots. CONSTITUTION:When a switch is closed, a shaft 14a and a feeding roller 16a rotate in an arrow direction as well as when a copying paper feeding mechanism 12a is set in motion, the uppermost copying paper is fed to a leading passage 28a due to the feeding action of the roller 16a and the separating action of a claw 10a. The front end of copying paper hits a conveying roller pair 48, correcting its attitude right whereby movement of the front end of the copying paper is checked and thereby this copying paper is bent. The copying paper acts on a first sensitive arm on a sensitive member 68 which is shifted to the first sensitive position from the nonsensitive position. Next, a permanent magnet 74 is positioned at one side of a responsive region 78 from a nonresponsive region 80. In addition, a sensitive mechanism 60 is shifted to the first sensitive position and a switch element 62 is operated whereby operation of the copying paper feeding mechanism 12a is stopped; the roller pair 48 operates by movement of a document mounting stand.</p> |
