いた。[Prior Art] Conventionally, in devices such as copying machines and laser beam printers that perform image processing on sheet materials, some users use a large amount of sheet materials, so in order to meet the user's requests, the main body of the device has an auxiliary device. Legs were attached to allow seat storage devices with different capacities to be used.

As shown in the figure, when sheets with the maximum capacity are loaded and installed in the device, the weight of the sheets and the long length from the bottom surface 6 of the cassette to the support part 7 that supports the cassette, which is subject to the load of the sheets, as shown in the figure. There was a problem in that the cassette itself was bent in the direction of arrow a. This deflection deformation is particularly noticeable on the side opposite to the sheet feeding side, which is reinforced by various members attached to the sheet feeding side that perform sheet feeding, whereas the side opposite to the sheet feeding side is reinforced. This is because there was no such member and it was weak. Furthermore, in the case of a 200-sheet cassette, the weight of the sheets themselves was relatively light and the length was short, so that such bending deformation did not occur.

A problem was occurring.

ている。In FIG. 3, the auxiliary legs 4 for mounting a multi-capacity cassette consist of a bottom surface 9, a side surface 10 on which the main body of the image forming apparatus is loaded, etc. on the bottom surface, as in the first embodiment. Ribs 11' are provided at two locations. The mounting direction of the multi-capacity cassette is the direction of arrow b, and the rib 11' of the auxiliary leg
has an inverted T-shape, and as shown in FIG. 4, the rib surface 11-1 comes into contact with the bottom surface of the cassette when the 500-sheet cassette is completely loaded. Also, when a 700-sheet cassette is installed, the rib surface 11-
2 contacts the bottom of the cassette. By contacting the rib surface 11-2, the contact area becomes larger than that of the rib surface 11-1, so that a heavier 700-sheet cassette can be supported. Both of these contacting bottom surfaces of the cassette are on the opposite sheet feeding side. As shown in FIG. 4, the bottom surface of the 500-sheet cassette is provided with reliefs 6-1 at two locations to escape the ribs, and one of the reliefs has a width that is approximately the same as the width of the protrusion 11-3 of the rib. This makes it possible to position the cassette in the lateral direction. Also, this relief 6-1 and the rib protrusion 11
-3 are each tapered so as not to interfere with the cassette installation, so that they read into each other when the cassette is installed.
