Title: Information processor
Inventor: MIYAMOTO YOSHIO
IPC: G06F1/26
Filed: 1990-07-04
Abstract: PURPOSE:To ensure the shared application of the power off control and the auto-off control and to simplify a power circuit by actuating an auto-off function by a CPU and switching off a power supply when the operation of an operator shows a switch-off instruction. CONSTITUTION:A switch signal latch circuit 15 is provided to decide a switch on or off instruction and latches this deciding result together with an on/off control circuit 16 which controls the start/stop of a power unit 2 through the circuit 15, and a set/reset circuit 17 which resets both circuits 15 and 16 with a signal 21 of a CPU 18. Then a power supply is forcibly started with no intervention of the CPU 18 with an on instruction. Then the CPU 18 saves the data into a back-up memory 33 and resets both circuits 15 and 16 via the circuit 17 to stop the operation of the unit 2 with an auto-on/off instruction. As a result, the data are never erased despite an erroneous switch-off operation and a power circuit is simplified and miniaturized.

Title: Image forming method
Inventor: IKEGAWA AKIHITO
IPC: B41M5/40
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To simplify a device constitution and processes by a method wherein a mold releasing material layer is formed on the surface of an image reception body, and an ink layer and the image reception body are brought into contact with each other through the mold releasing material layer. SOLUTION: On the surface of an image reception body 5 which is constituted of a transparent insulating material, a silicon oil 4 which is a mold releasing material is coated by an oil coating roller 3 by a specified layer thickness. On the surface of an ink coating roller 1, an ink 2 is carried by a specified layer thickness. Then, at a contact part between the image reception body 5 carrying the silicon oil layer, and the ink coating roller 1, a laser beam 6 is cast through the transparent image reception body 5 to the ink layer. The laser beam 6 is selectively cast to the ink layer 2 based on an image information, and the ink at the cast part is heated, and the ink tenacity decreases. As a result, the ink at the area where the laser beam has been cast transfers onto the image reception body 5, and an image is formed.  At this time, on the image reception body 5, an ink image of which the tenacity has decreased is formed on the silicon oil layer, and for this reason, the ink is prevented from transferring to a non-image part by the mold releasing property.

Title: Optical scanning device
Inventor: ITO TOSHIO
IPC: H04N1/10
Filed: 1994-05-20
Abstract: PURPOSE:To ensure that a mirror is made vibrationproof so as to prevent the image-forming position of image reflected light from being moved by vibration by providing elastic foam that is held to a carriage and energizes the mirror for vibrationproofing. CONSTITUTION:A carriage 1 has a cushion holding portion 29A for holding a cushion 30 of elastic foam on the back of a mirror. A cushion holding member 29 formed by the bending of a metallic plate is installed. The cushion holding portion 29A is opposed to the back of the mirror while being almost parallel to the surface of the mirror. Foam that absorbs external impact by being deformed instantly and restores slowly from its deformed state, e.g. polyurethane foam containing asphalt, is used as the vibrationproofing cushion. Therefore, the amplitude of vibration caused by the scanning of the carriage is attenuated in a short time and so high-speed scanning is made possible. Moreover, since the distance required to attenuate vibration can be reduced, a small, albeit high-speed scanning device can be obtained.
