Paper feeding device and image forming apparatus

摘要

A paper feeding device includes a pressing member, a restricting mechanism, and an interlocking mechanism. The pressing member is movable up and down between a pressing position and a release position. The pressing position causes a pressure to a paper sheet against the feed roller. The release position causes a release of the pressure. The restricting mechanism is movable between a restricting position and a removal position. The restricting position causes a restriction on moving up of the pressing member to the pressing position. The removal position causes a removal of the restriction. The interlocking mechanism is configured to move the restricting mechanism to the removal position in interlock with rotation of the feed roller.

主权项

1. An image forming apparatus, comprising:
a paper feeding device configured to press a paper sheet placed on a tray against a feed roller to feed the paper sheet to a feeding destination by rotation of the feed roller; and an image forming portion configured to form an image on a paper sheet fed from the paper feeding device, wherein the paper feeding device includes:
a pressing member movable up and down between a pressing position and a release position, the pressing position causing a pressure to a paper sheet against the feed roller, the release position causing a release of the pressure;a restricting mechanism movable between a restricting position and a removal position, the restricting position causing a restriction on moving up of the pressing member to the pressing position, the removal position causing a removal of the restriction; andan interlocking mechanism configured to move the restricting mechanism to the removal position in interlock with rotation of the feed roller, the interlocking mechanism includes:
an interlocking rotating body configured to rotate in interlock with rotation of the feed roller;a contacting member configured to move the restricting mechanism in contact with the restricting mechanism; anda pressure contact member configured to bring the interlocking rotating body into pressure contact with the contacting member, and the contacting member is configured to press the restricting mechanism and move the restricting mechanism to the removal position by an interlocking action in association with the rotation of the feed roller in pressure contact, to stop the interlocking action and be brought into slidable contact with the interlocking rotating body in a rotating state after the restricting mechanism has reached the removal position, and to press the restricting mechanism until the rotation of the feed roller stops.
