Publication number: 20030117610Abstract: A film holder comprises a base member and a film pressing member, between which a film is sandwiched. The film is placed on the base member. The film pressing member has a spring portion and a contact portion. When the film pressing member is closed while a film is on the base member, the contact portion comes into contact with a surface of the film and the spring portion is elastically deformed, causing the film to be tensioned outward and to change from a curved condition to a flat condition. Thus, the film is sandwiched between the base member and the film pressing member in a flat condition, so that an image developed on the film can be sensed or read with high accuracy.Type: ApplicationFiled: December 4, 2002Publication date: June 26, 2003Applicant: PENTAX CorporationInventor: Yuichi Kurosawa

Patent number: 5198946Abstract: A head drive mechanism associated with a disk drive device is provided for driving to rotate a magnetic disk. A magnetic head is driven and a signal is recorded on the magnetic disk or a signal already recorded on the disk is reproduced. The head is mounted on a carriage, on which a protrusion is provided, and is driven in a direction parallel to the surface of the disk with the protrusion being engaged with a lead screw when the lead screw is rotated. When the carriage abuts against a stopper located at a predetermined position, the movement of the head in the radial direction of the disk is prevented. A control system further controls rotation of the screw in the direction parallel to the surface of the disk such that the carriage is held abutting against the stopper. Since the protrusion is forced against the thread portion of the screw, the head is moved away from the disk.Type: GrantFiled: August 14, 1992Date of Patent: March 30, 1993Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventor: Yuichi Kurosawa
