Title: Medium guide apparatus for scanning system
Inventor: JIEFURII NOTSUKUSU
IPC: B41J2/44
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce the medium jam in an initial medium loading process by holding the surface-surface contact between the surfaces of a record medium and an internal drum and maximizing it, when the front end of the record medium passes on the drum surface toward the exit of a drum and/or into the exit. SOLUTION: When a hollow shielding material 42 accompanied with a laser scanning mechanism is displaced vertically along a drum 12 by a transfer mechanism during scanning, a retractable plate assembly 46 does not interfere the hollow shielding material 42. A means such as a brush for applying a pressure load is fixed to a distal rim part 52 of a fan-shaped member 50, a medium 14 is brought into a complete contact with a drum 12, and the medium floating quite near a laser scanning beam is substantially contracted during scanning operation. A cantilever member 44 paired with a flange 54 is adapted to hold the surface-surface contact between the drum 12 and a record medium 14 during feeding of the subsequent medium, which prevents the jam, floating, or buckling of the record medium 14 in the drum 12.

Title: Liquid crystal display device and power source unit for liquid crystal display device
Inventor: KABUTO NOBUAKI
IPC: G02F1/133
Filed: 1989-04-14
Abstract: PURPOSE:To prevent charge from being accumulated in a liquid crystal cell by means of turning on/off a power source by supplying a selected potential to a corresponding gate bus in a liquid crystal panel for a prescribed time by means of all analog switches in a vertical scanning circuit when a detecting circuit detects the turned on/off state of the power source. CONSTITUTION:When a detecting circuit 4 detects the turned on/off state of the power source, the selected potential is supplied by the respective analog switches in a vertical scanning circuit 2, and respective picture element transistors (TR) 13 connected to respective gate buses are all turned on. By inputting the potential equivalent to the potential of a facing common electrode instead of a video signal to a horizontal scanning circuit 3, the potential is supplied through respective drain buses D1 and D2 and the respective TRs 13 to the respective liquid crystal driving electrodes, and as a result, a voltage is not impressed to the respective liquid crystal cell 14. Thus by preventing the charge in the liquid crystal display panel from being accumulated at the time of turning on/off the power source, a baking phenomenon and a display deterioration such as a flicker are not generated even when the turning on/off operations of the power source are repeated.
