Abstract

PURPOSE: To hold the original in a prescribed position stably without fluttering, by providing a pressure-fixing plate switching device which controls the switching movement so that the movement speed near the closure position of the original pressure-fixing plate may be lowered.
CONSTITUTION: Gear 18 fixed to rotary shaft 17 fitted to the back end of pressure-fixing plate 7 gears with fan-shaped gear 20 which rotates with fixed shaft 19 as the center, and slide rod 20a of this gear 20 is provided with groove 20b, and pin 22 provided on crank board 21 is linked to this groove. Crank board 21 is fixed to driving shaft 24 of motor unit 23, and the outside circumferential face constitutes a cam face to give signals to opening position detection sensor 25 and closure position detection sensor 26 provided near the outside circumference of crank board 21, and motor unit 23 controls driving and stopping. As a result, the original is prevented from fluttering, and the original can be held in a prescribed position stably.
