SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS

摘要

A sheet feeding device includes a lifting plate, a pickup roller, a lifting and lowering mechanism of the lifting plate and an end cursor. The end cursor has a cursor main body and a turning cursor plate. The turning cursor plate is coupled to the cursor main body turnably around a turning shaft extending in a width direction orthogonal to the conveying direction and slidably along a lifting and lowering direction of the lifting plate. The turning cursor plate is configured to be turned toward the downstream side in the conveying direction around the turning shaft by being pushed up with the lifting of the lifting plate while the turning shaft is moved upward so that the sheet is shifted toward the downstream side along an upper surface of the lifting plate with respect to the lifting plate.

主权项

1. A sheet feeding device comprising:
a lifting plate on which sheets are to be stacked, in a sheet feeding cartridge; a pickup roller configured to feed the sheet to a conveying path; a lifting and lowering mechanism configured to turn the lifting plate with its upstream side end in a conveying direction as a turning point so as to lift and lower its downstream side end in the conveying direction with respect to the pickup roller; and an end cursor configured to be movable along the conveying direction and to abut against an upstream side edge of the sheet in the conveying direction so as to align the sheet in the conveying direction, wherein the end cursor includes:
a cursor main body; anda turning cursor plate coupled to the cursor main body turnably around a turning shaft extending in a width direction orthogonal to the conveying direction and slidably along a lifting and lowering direction of the lifting plate, and wherein the turning cursor plate is configured to be turned toward the downstream side in the conveying direction around the turning shaft by being pushed up with the lifting of the lifting plate while the turning shaft is moved upward so that the sheet is shifted toward the downstream side along an upper surface of the lifting plate with respect to the lifting plate.
