Abstract

PURPOSE: To make possible releasing of impact of an original platen with simple constitution by sliding a groove of a predetermined shape of a cylindrical member which is defined of turning by a spring and a pin integral with the original platen thereby braking the original platen.
CONSTITUTION: When an original platen 28 moves backward in the direction opposite from the arrow x direction upon ending of exposure, the sliding pin 35 protrusively provided to the platen 28 fits into the groove 35 of a cylincrical member 27 which is defined of turning by a spring 32, thereby sliding the groove 35. The member 27 is turned by the spiral part 30c of the groove 30 against the elastic force of the spring 32 and braking force is acceleratively applied to the platen 28 by the friction force between the pin 35 and the groove 36, thus the cushion releasing of the original platen is accomplished by the simple constitution and the original platen is stopped in the predetermined position without any deviation.
