<p>PROBLEM TO BE SOLVED: To make a paper container retractable smoothly without any backlash in a simple structure as well as to improve the operability and a work feeling by using a positive a slip-off preventing mechanism of this paper container fitting in the vertical direction. SOLUTION: In the case where a paper feeding cassette 22 as a paper container, by way of example, is housed in a device body 21, it is necessary to shift a notch part 27 at a rear part of the paper feeding cassette 22 to a projection 31 in the vertical direction in time of fitting for cassette slip-off prevention in the vertical direction, but the paper feeding cassette 22 and a slide bearing member 37 both are able to turn round a connecting part at the inner part along a long hole 47 as using the connecting part at this side as a turning center, so that the notch part 27 and the projection 31 are made easily fittable along with a smooth movement with no backlash of the paper feeding cassette 22 by the slide bearing member 37.</p> |
