CONSTITUTION:With start of a copying action, a drive system 3 first turns and a release member 14 touches an automatic release member 13. Thus the member 14 turns clockwise the member 13. As a result, a cable 12 is pulled to turn downward a hook part 7a of a hook lever 7 agaist a spring 8. Thus the hook of an original board 2 is released, and at the same time a drive member 5 provided to the system 3 engages a hook bar 6 of the board 2 to start the move of the board 2. On the other hand, when the manual release is desired for the board 2, the tip of a manual release lever 9 is pressed down. Thus the part 7a is turned downward by the cable 12 regardless of an automatic release lever 13 to release the hook of the board 2. |
