Patent number: 11274007Abstract: A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.Type: GrantFiled: May 20, 2020Date of Patent: March 15, 2022Assignee: Canon Kabushiki KaishaInventors: Yuichi Obara, Masaaki Takeuchi

Patent number: 5059133Abstract: An electronic connector which has a plurality of contacts associated in one or more rows in a connector housing, a shape memory spring associated in the connector housing for driving the contacts, the shape memory spring transmitting a recovery force generated when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher and returning to the shape before the shape memory recovery by the spring force of the contact when the shape memory spring reaches below its transformation temperature. Thus, the electronic connector can mount or dismount contacts at each other without inserting or removing force or substantially without inserting or removing force in a simple structure with less number of parts.Type: GrantFiled: June 11, 1990Date of Patent: October 22, 1991Assignee: The Furukawa Electric Co., Ltd.Inventors: Toshiya Hikami, Koji Yoshida, Yuichi Obara, Kenichi Fuse
