Claim:
A sheet conveying apparatus having: a pair of first conveying rotary members configured to convey a sheet; an openable and closable conveying guide configured to guide the sheet conveyed by said pair of first conveying rotary members; a pair of second conveying rotary members configured to convey a sheet guided by said openable and closable conveying guide; and an obstructing member movable between a first position and a second position, wherein the obstructing member positioning at the first position allows a sheet conveyed by said pair of first conveying rotary members to come into the nip portion of said pair of second conveying rotary members and the obstructing member positioning at the second position obstructs an entrance to the nip portion of said pair of second conveying rotary members so that the obstructing member prevents a sheet conveyed by said pair of first conveying rotary members from coming into the nip portion of said pair of second conveying rotary members; wherein in a state in which said conveying guide is closed said obstructing member positions at the first position, and the sheet conveyed by said pair of first conveying rotary members is guided to said pair of second conveying rotary members by said openable and closable conveying guide, and in the state in which said conveying guide is opened, said obstructing member is positioned at the second position, and the sheet is conveyed to outside of a main body of said sheet conveying apparatus, wherein said obstructing member positioning at the second position covers at least a part of a peripheral surface portion of one of said pair of second conveying rotary members, and wherein said obstructing member is pivotably supported, and a pivot center of said obstructing member is provided downstream with regard to the nip portion of said pair of said second conveying rotary members in a conveying direction of said pair of second conveying rotary members.
