Patent number: 6612762Abstract: The present invention is intended to provide an economical printer which is simple in structure and uses a common tray but is capable of adapting itself to various recording media of different shapes. Adapters in which recording media can be firmly held can be selectively mounted in the tray. An adapter 24 has an oval opening 24a in which a recording medium 30 can be placed. The contour of the adapter 24 can fit into a recessed portion 23a formed in the tray 23. The recording medium 30 is firmly held in the adapter 24. When the adapter 24 is mounted in the recessed portion 23a in the tray 23, a keyway 23b and a protrusion 24b engaging the keyway 23b prevent the adapter 24 from shifting out of position; the adapter is held in the tray 23. Prints can be made in accurate positions on the recording medium 30.Type: GrantFiled: May 30, 2000Date of Patent: September 2, 2003Assignee: Seiko Precision Inc.Inventors: Motoharu Sakurai, Satoru Tada, Naoki Tanabe, Mikio Amakasu

Patent number: 6059464Abstract: A camera comprises a film cartridge chamber for accommodating a film cartridge containing a film. The film cartridge has a first rotational shaft. An operating member is mounted for rotation in first and second opposite directions by manual operation for winding and rewinding the film, respectively. A second rotational shaft is provided for connection to the operating member during rotation of the operating member in the first direction. A wheel train transmits rotational movement of the operating member to the first rotational shaft to wind and rewind the film. A first clutch mechanism disconnects transmission of rotational movement by the wheel train when a tensional state of the film is generated.Type: GrantFiled: November 19, 1998Date of Patent: May 9, 2000Assignee: SEIKO Precision Inc.Inventor: Motoharu Sakurai
