Patent ID: 8500122

Claim:
A sheet conveying apparatus comprising: a pair of sheet conveyance rotating members including a first rotating member and a second rotating member which nip a sheet and convey the sheet; and a moving mechanism which brings the first rotating member and the second rotating member into contact with each other and which separates the first rotating member and the second rotating member from each other, wherein the moving mechanism includes a first cam which moves, against a biasing force in a direction in which the first rotating member abuts against the second rotating member, the first rotating member so that the first rotating member separates from the second rotating member, a second cam which moves, against a biasing force in a direction in which the second rotating member abuts against the first rotating member, the second rotating member so that the second rotating member separates from the first rotating member, and a driving portion which drives the first cam and the second cam, wherein each of the first cam and the second cam has such a cam curved surface that when the first cam and the second cam are rotated by the driving portion, each cam curved surface moves the first rotating member and the second rotating member to each maximum separated position where the first rotating member and the second rotating member are separated from each other, and when the first rotating member and the second rotating member are abutted against each other, each cam curved surface moves the first rotating member and the second rotating member with different timing from each maximum separated position.
