PURPOSE:To prevent the movement at the exchanging of microfiches by pressing one end of the microfiche by means of a spring member. CONSTITUTION:A movable frame 17B moving in a Y direction is provided on a base frame 17A moving in an X direction, and a positioning member 29 is mounted on the frame 17B freely turnably by means of a projection 22. When the movable frame is pulled out to this side, the projection 21 of the member 29 engages to the sloped part of the side wall 172 of the base frame, and an upper glass plate G2 and the member 20 turn with the projection 22 as a fulcrum, and space automatically from a lower glass plate G1, thereby permitting exchanging of microfiches. When the microfiche is inserted, the leading end part of the fiche is pressed and fixed between a spring member 25 provided to the center of the member 20 and the plate G2 and therefore the occurrence of position deviation in exchanging of the microfiches is obviated. |
