Patent ID: 7979002

Claim:
A sheet processing apparatus comprising: an opening/closing member turnably supported by an apparatus body; a first conveyance portion which nips and conveys a sheet; a second conveyance portion which nips and conveys a sheet; a conveying guide which is movably supported on the opening/closing member and which guides a sheet from the first conveyance portion toward the second conveyance portion; and a guide portion which is provided on the opening/closing member and which guides the sheet from the first conveyance portion toward the second conveyance portion, wherein the guide portion forms a conveying path, through which the sheet is conveyed, together with the conveying guide, wherein in a case where a sheet is not nipped by the first conveyance portion and the second conveyance portion, the conveying guide is moved with the opening/closing member while opening the opening/closing member, and in a case where a sheet is nipped by the first conveyance portion and the second conveyance portion, a movement of the conveying guide is regulated by the nipped sheet so that the conveying guide and the guide portion are separated from each other by the nipped sheet while opening the opening/closing member, thereby opening the conveying path.
