Abstract
When a sheet feeding cassette (10) is mounted on an image forming apparatus or the like, a forward portion of a mounting plate (13) is urged upward so that an upper surface of the forward portion of the mounting plate (13) is brought into contact with a feed roller (11). A pair of non-slip pads (14a) and (14b) is affixed to the upper surface of the forward portion of the mounting plate (13). The non-slip pads (14a) and (14b) are members each having a plane shape of approximately L or its reversed shape and made of, for example, a rubber plate. The non-slip pads (14a) and (14b) are affixed to such a position that they do not come into direct contact with the feed roller (11). Consequently, when sheets are fed, the last sheet is not directly nipped strongly by the feed roller and the non-slip pads, to produce no buzzing noise. In addition, the non-slip pads (14a) and (14b) are in the vicinity of the feed roller (11). Accordingly, the non-slip pads (14a) and (14b) perform the function of preventing the last sheet from being fed together with the other sheets if the number of the sheets is reduced, that is, preventing the sheets from being fed together.
