Title: Image display system
Inventor: KIMURA KAZUO
IPC: H04N5/66
Filed: 1986-03-24
Abstract: PURPOSE:To insure the picture quality interference against arising if a display quickly changes by controlling the jump ratio of a jump scan with the aid of a signal specifying a speed that the displayed contents change. CONSTITUTION:According to an external input control signal instructing whether scrolling is executed or not a CPU 16 modifies a read top address in a VRAM 15 storing a display signal and scrolls an image displayed on a liquid crystal display 11. When a control circuit 14 receives the signal instructing the execution of scrolling, it supplies a control signal to a scan circuit 13 so as to execute the jump scan with a low ratio. When receiving the signal to deny scrolling, the control circuit 14 inputs the control signal to the scan circuit 13 so as to execute the jump scan with a great scan ratio. Thus a scan is modified when a displayed changes quickly so that the picture quality interference will not occur.

IPC: G03G15/00
Filed: 1980-05-15
Abstract: PURPOSE:To prevent adsorption of carriers on a clamping member by positioning  the surface of the clamping member further from a developing electrode than the  surface of a photoreceptor. CONSTITUTION:A sheetlike photoreceptor 2 let-out from a let-out roll 3 as shown by an arrow B passes through an opening 4 and goes to the outside of a drum 1, thereby covering the peripheral surface thereof.

A sealing member 6 which is used to close the opening 4 prevents the entry of the developer into the drum 1 and clamps the photoreceptor 2. This sheet 6 is retracted from the cylindrical surface formed by the photoreceptor 2. Then, in spite of expanding of the spacing from the developing electrode, no effect is given to the developing of image parts, and the electric field due to a developing bias power source is weakened. As a result, the sticking of the carrier to the seal 6 is prevented.
