Abstract
A stack of sheets (59) are placed on a movable bottom plate (53) of a cassette (52) and aligned with a leading edge and a side edge of the cassette (52). A corner separator (66) is provided at the corner of the leading and side edges. The bottom plate (53) is raised so that the top sheet (59) engages with a single feed roller (61) which is disposed adjacent to the corner separator (66). A skew preventing roller (68) engages with the top sheet (59) upstream of the feed roller (61)in a feed direction of the sheet (59). A manual lever (88) is provided to move the skew preventing roller (68) and an arm (56) for raising the bottom plate (53) clear of the cassette (52) for the purpose of detaching or inserting the cassette (52) in a frame (94). In a released position of the lever (88), a portion (122) of the lever ( 88) blocks insertion and detachment of the cassette (52) while the skew preventing roller (68) and raising arm (56) are in operative positions.
