Document Type and Number:
WIPO Patent Application WO/2013/108467
Kind Code:
A1
Abstract:
A sheet ejection device comprises an ejection roller pair (20) which ejects a sheet by a pressure contact portion (N) in which a first roller (21) and a second roller (22) are in pressure contact with each other. In the first roller (21), protrusions (41) that protrude in a roller diameter direction in order to push the back end of the sheet ejected with the rotation of the first roller (21) are formed. The protrusions (41) are provided in a flange (45) at a predetermined distance from the peripheral end (43a) of a cylindrical portion (42) of the first roller (21) in a sheet width direction. The distance from the center of rotation of the flange (45) to the front end (41c) of each of the protrusions (41) is equal to or less than the radius of the cylindrical portion (42).
