Patent number: 7722040Abstract: In an embodiment of the invention, a cam of a pitch adjustment mechanism can be slid and moved along a first shaft. When a sheet is a standard paper, the pitch adjustment mechanism is ejected from an adjustment position by an urging force of a movement spring and is moved to a standby position, and slide contact between the cam and a second shaft is released. When a sheet is a thick paper, a solenoid is turned on, the pitch adjustment mechanism is disposed at the adjustment position by a plunger, and it is prevented that the registration roller pair abruptly come in contact with each other after the thick paper passes through.Type: GrantFiled: September 2, 2008Date of Patent: May 25, 2010Assignees: Kabushiki Kaisha Toshiba, Toshiba TEC Kabushiki KaishaInventor: Toshihiro Matsushima
