<p>PURPOSE:To eliminate the interference of the upper part of a sheet rear end regulating plate provided at a receiving plate at the time of being put into/out of an image forming device even when the receiving plate is placed in the inclined state due to its front end moving up in association with the decrease of cut sheets. CONSTITUTION:A sheet rear end regulating plate 29 provided at a receiving plate according to the size of cut sheets is formed of a fixed supporting plate 30 fitted to the receiving plate 24, a movable regulating plate 31 pivotally supported in the eccentric state at the fixed supporting plate 30, and a spring 32 for energizing the movable regulating plate 31 rotatably toward the bottom plate 22a of a cassette body 22. The upper edge 30c of the fixed supporting plate 30 is formed into such height as not to protrude from the upper edge 22c of the cassette body 22 at the maximum ascent time of the receiving plate 24. The movable regulating plate 31 is provided with a high edge part 31b formed to be the approximately same height as the upper edge 22c of the cassette body 22 at the time of placing the maximum quantity of the cut sheets, and a low edge part 31d formed into such height as not to protrude from the upper edge 22c of the cassette body 22 at the maximum ascent time of the receiving plate 24.</p> |
