发明名称 Sheet conveying apparatus and image forming apparatus
摘要 A sheet conveying apparatus, including: a first conveying portion; a second conveying portion arranged downstream of the first conveying portion; a shutter member rotated by the pressure of the sheet and including a plurality of abutment surfaces against which a leading edge of the sheet conveyed by the first conveying portion abuts to correct a skew feed of the sheet; and an urging portion which provides the shutter member with an urging force for positioning one abutment surface at an abutment position at which the leading edge of the sheet abuts against the one abutment surface, the urging portion providing the shutter member with an urging force for rotating the shutter member to position another abutment surface at the abutment position after the leading edge of the sheet is nipped by the second conveying portion.

主权项 1. A sheet conveying apparatus, comprising: a first conveying portion which conveys a sheet; a second conveying portion provided downstream of the first conveying portion which conveys the sheet conveyed by the first conveying portion; a shutter member which rotates by being pressed by the conveyed sheet and includes a plurality of abutment surfaces against which a leading edge of the sheet conveyed by the first conveying portion abuts, the plurality of abutment surfaces being formed in a peripheral direction of the shutter member; a shaft connected to the shutter member to rotatably support the shutter member; a first rotary member connected to the shaft; a second rotary member connected to the first rotary member; anda biasing portion connected to a part of the second rotary member located offset with respect to a rotation center of the second rotary member to hold the second rotary member at a predetermined position and to position one abutment surface of the plurality of abutment surfaces upstream of the second conveying portion,wherein the second rotary member rotates at a speed ratio of the second rotary member to the first rotary member when the first rotary member rotates, the speed ratio being the same number as a number of the plurality of abutment surfaces.
