摘要

A sheet pickup apparatus and image forming apparatus are provided. The sheet pickup apparatus includes a roller support member rotatably disposed in a sheet feeding unit and comprising roller support portions connected by a hinge, a driving shaft rotatably disposed in an end of the roller support member to transmit rotational force to the roller support member, a pickup roller rotatably disposed in another end of the roller support member, a damper member disposed to absorb impact force by limiting rotation of the roller support member, and a power transmitting member disposed in the roller support member to transmit the rotational force to the pickup roller.

主权项

1. A sheet pickup apparatus, which is disposed in a sheet feeding unit of an image forming apparatus, the sheet pickup apparatus comprising:
a roller support member rotatably disposed in the sheet feeding unit, the roller support member comprising at least two roller support portions connected by at least one hinge; a driving shaft rotatably disposed in one end of the roller support member connected in the sheet feeding unit, the driving shaft to transmit rotational force to the roller support member; a pickup roller rotatably disposed in another end of the roller support member; a damper member disposed to absorb impact force by limiting rotation of the roller support member; and a power transmitting member disposed in the roller support member, the power transmitting member to transmit the rotational force of the driving shaft to the pickup roller, wherein, when the driving shaft receives the rotational force from a driving source of the sheet feeding unit, the roller support member is rotated to hit against the damper member, and then a roller support portion in which the pickup roller is disposed is rotated so that the pickup roller is brought into contact with a sheet loaded in the sheet feeding unit and picks up the sheet.
