PURPOSE:To simplify the construction and the operation by providing a hooking means to hook a paper tray at a retreated position by the operation of an operation lever to a hooking position and a releasing means to release the hooking by the operation of the operational lever to the releasing position. CONSTITUTION:The first hooking piece 108 and the second hooking piece 110 are provided at the center of a paper tray 38, while a rail part 106 bent downward is provided on the side brim of a connection part 102. In this construction, when an operation lever 82 is operated to the hooking position, a pawl part 118 of the first rotating member 96 is fitted in a hooking hole 112, and the first hooking piece 108 is hooked in the side wall part 90 for hooking the paper tray 38 at its retreated position. When the operation lever 82 is operated on the releasing position, the rail part 106 is brought in touch with a connecting part 94 of the first rotating member 96 to release the hooking. This construction permits to hook and release the paper tray 38 by the single operation lever 82 easily and simply. |
