Abstract

PURPOSE: To achieve the prevention of occurrence of mis copying, jam mode, etc. owing to mis-insertion and mis-alignment of originals by starting conveying and copying motions of the original only when the original has been inserted.
CONSTITUTION: When no original is inserted and a microswithch 1 is OFF, the output of an inverter 5 becomes low potential and a NAND circuit 22 cuts off the fall pulse from a differentiation circuit consisting of a capacitor 10 and resistance 11. Hence, a start signal is generated only when the insertion of the original is checked with the circuit 22. An insertion control circit 23, upon receiving of this start signal, drives an inlet solenoid 24 and motor 25, thereby stopping the original in the exposure position on the original base of the main unit of the copying machine and at the same time causing the copying motion to be started.After this, a discharge control circuit 28 upon receiving of the discharge signal owing to the exposure completion of the original and end of its copying turns ON an outlet solenoid 29, causing discharge motion to be accomplished. Thereby, mis-copying, jam mode, etc. owing to mis-insertion and mis-aligngment of the originals may be prevented.
