Publication number: 20050270928Abstract: An optical disc device is disclosed. The optical disc device includes a thermal head that is disposed at a side opposite to an optical pickup, which irradiates a laser beam for writing and erasing information, relative to a mounted optical disc, and is configured to bring a thermal head into contact with a label, which is made of a thermosensitive information display film attached on a label-side surface of the mounted optical disc, to write visible information on the label. The optical disc device also includes a low-speed rotation mechanism configured to rotate the optical disc at a low speed by a motor when the thermal head writes visible information on a label, in addition to a high-speed rotation mechanism, such as a spindle motor, configured to rotate the optical disc at high speed when the optical pickup records or reproduces the information.Type: ApplicationFiled: May 12, 2005Publication date: December 8, 2005Inventors: Hiroki Sugahara, Yasushi Okada, Katsuhiko Okabe, Akihiko Okamoto, Hiroshi Koide

Patent number: 4191104Abstract: A printer having a plurality of swingable and rotatable printing character bearing endless belts each of which is stretched around a pair of rotatable wheels, one of which is adapted to be swung into contact with a platen. The other wheel is adapted to be driven by a driving shaft to select the character to be printed. The belts are selectively swung in response to a signal from a control circuit to abut the characters selected against the platen onto a paper therebetween, and the belts are also selectively moved by the other wheels in response to electrical signals which drive a drive shaft which drives the other wheels.Type: GrantFiled: December 21, 1977Date of Patent: March 4, 1980Assignee: Copal Company LimitedInventor: Katsuhiko Okabe

Patent number: 4173420Abstract: The paper feeding mechanism in a printer has a paper feeding roller and a pressure roller cooperating with the paper feeding roller so as to feed a paper sandwiched therebetween for the printing operation of the paper, and the pressure roller is mounted on a resiliently energized swingable lever so that the pressure roller is releasably urged against the paper feeding roller for feeding the paper. The paper feeding mechanism further comprises a paper arresting member adapted to disengageably contact with and arrest the paper when actuated, an actuating lever coupled with swingable lever as well as the paper arresting member and a driving solenoid provided with a plunger actuated thereby and coupled with the actuating lever.Type: GrantFiled: March 31, 1978Date of Patent: November 6, 1979Assignee: Copal Company LimitedInventor: Katsuhiko Okabe

Patent number: 4129075Abstract: Line printer having a plurality of coaxially arranged rotatable printing rings each bearing a series of characters to selectively effect printing on a paper and a platen movable toward in contact with and away from the printing rings so as to effect printing on the paper interposed between the platen and the printing rings when the platen abuts against the printing rings, each of the printing rings being selectively arrested by a select lever actuated by the printing signal from a control system of the printer thereby positioning desired characters of the respective printing rings in the printing position at which the platen abuts against the printing rings so that a line of printing is produced on the paper simultaneously. The printer comprises a mechanism for additionally printing a mark such as an underline and the like adjacent to particular characters printed on the paper. The mechanism is moved to the printing position by a signal from the control system.Type: GrantFiled: November 4, 1977Date of Patent: December 12, 1978Assignee: Copal Company LimitedInventor: Katsuhiko Okabe

Patent number: 4104967Abstract: Line printer having a plurality of rotatable printing rings coaxially arranged adjacent each other and carrying on the peripheries thereof a plurality of characters for the printing and a movable roller pad adapted to abut against the printing rings at the predetermined printing position so that the selected characters of the printing rings held at the printing position are simultaneously printed on a paper held between the printing rings and the roller pad so as to form simultaneously a line of printing thereon in each printing cycle. The printing rings are rotated in the same direction in each printing cycle in order to eliminate a complicated mechanism for reciprocally driving the printing rings.Type: GrantFiled: November 4, 1977Date of Patent: August 8, 1978Assignee: Copal Company LimitedInventor: Katsuhiko Okabe

Patent number: 4095686Abstract: Printer having swingable printing rings which are selectively swung against a platen to print a line of selected characters on a paper by selecting a desired character from a plurality of characters provided on the periphery of each printing ring during the rotation thereof about its axis. Each printing ring is rotatably supported on a swingable printing ring supporting lever which is in turn swingably supported on a driving shaft. A plurality of driving gears are secured to the driving shaft and each of the driving gears meshes with a gear integral with the respective printing ring so as to rotate the same about its axis for selection of a desired character during the rotation thereof. Each printing ring supporting lever is urged by a spring so as to move the printing ring thereon apart from the platen. A plurality of driving levers are swingably supported on the driving shaft and each driving lever is engaged with the respective printing ring supporting lever.Type: GrantFiled: July 1, 1977Date of Patent: June 20, 1978Assignee: Copal Company LimitedInventor: Katsuhiko Okabe

Patent number: 4089263Abstract: An impact printer in which a printing drum having a plurality of lines each containing different characters is associated with printing hammers. The printing hammers are driven into contact with the characters by a driving shaft having a driving projection thereon. The driving projection is separated into driving projection sections which are axially and radially displaced along the driving shaft. Each section will selectively engage different printing hammers so that all hammers will not operate at once for the same characters. The characters in the lines are also displaced angularly of the printing drum so that some of the characters in one line will be printed responsive to one driving projection and the other characters in the one line will be printed in response to the other driving projection section.Type: GrantFiled: February 10, 1977Date of Patent: May 16, 1978Assignee: Copal Company LimitedInventors: Katsuhiko Okabe, Yoshiyuki Sudo

Patent number: 4013159Abstract: A printer having a frame, a printing head and a platen, either one of the head and the platen is fixedly secured to the frame while the other is movably mounted on the frame by movable supports so that they are moved relatively toward and away from each other for the printing operation of a paper held therebetween when abutted against each other. The movable supports comprises a pair of supporting members each movably mounting other of the head and the platen independently from each other. Each of the supporting member is biased by a spring so as to urge the other of the head and the platen against the one of the head and the platen independently from each other. Thus, the parallel relationship between the head and the platen when abutted against each other for the printing operation is insured.Type: GrantFiled: May 21, 1975Date of Patent: March 22, 1977Assignee: Copal Company LimitedInventor: Katsuhiko Okabe
