Claims

[Scope of utility model registration request]

A paper feed cassette that can be inserted into and removed from the machine body in the paper feed direction, a pickup roller that is biased so as to be in constant pressure contact with the upper east surface of the sheets in the cassette, and a pickup roller that is installed in the machine body on the downstream side in the paper feed direction. In a device for preventing sheets from remaining when a cassette is removed from a friction separation sheet feeding device, which has a feed roller that is attached to the feed roller and a reverse roller that presses against the feed roller by sandwiching the sheet path, the device is integrated with the fixed shaft that holds the pickup roller. The cam member provided in the cassette moves integrally with the cassette.
and a member that engages with the cam member, the shape of the cam member being displaced upward by the engaging member in the process of pulling out the cassette from a predetermined mounting position, and causing the pickup roller to face downward. A sheet-remaining prevention device characterized in that it has a shape that causes it to rise against the urging force of.
