Abstract

PURPOSE: To perform sure copying material feeding by providing the means of detecting whether transfer material is surely gripped in a gripper or not in the copying material feeder which grips the copying material in the gripper and conveys the same.
CONSTITUTION: Transfer material P (P') supplied by feed rollers 10 abuts against a static timing roller 51 and forms a deflection L1 and this causes a microswitch 103 to actuate. (Fig. A) A timing roller 51 actuates to start fast feeding so that the transfer material P (P') abuts against a gripper 53. (Fig. B) At this time, the deflection L1 is kept formed and the microswitch 103 keeps actuating. When the copying material P (P') is surely gripped by the gripper 53, the deflection becomes L2 and this causes the microswitch 103 to stop and the timing roller 51 to stop, thus ordinary feeding is resumed. (Fig. C) If the feed amount of the copying material P (P') is insufficient owing to the slip or the like of the copying material P (P') and the microswitch does not actuate as the deflection does not become L1 in the Fig. A, the copying operation is stopped.
