Title: Cleaning assisting device for electrophotographic photoreceptor
Inventor: WATANABE TOSHIO
IPC: G03G21/10
Filed: 1980-05-29
Abstract: PURPOSE:To use a cleaning assisting device while the force of pressing to a photoreceptor is weakened by forming a cleaning blade by laminating a conductive layer and insulating layer alternately, and by applying an AC voltage to conductive layers. CONSTITUTION:The external circumference part of a photoreceptor 1 consists of a conductive layer 1a, photosensitive layer 1b and dielectric layer 1c, and a cleaning blade 2 is formed by laminating a conductive layer 2a and insulating layer 2b repeatedly and alternately; respective conductive layers 2a are connected to an AC power source 4. This cleaning blade 2 is brought into light contact with the photoreceptor 1 and an AC high voltage is applied to the conductive layers 2a, and consequently an unbalanced electric field is established between the conductive layer 1a of the photoreceptor 1 and the conductive layers 2a of the blade 2. As a result, charges of the photoreceptor surface and toner are eliminated, and the toner is stirred to improve mechanical scraping-off operation.

IPC: H04N5/225
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve an S/N at the time of photoelectric conversion while easily enlarging a photographing screen by arranging and synthesizing image information which is photoelectrically converted by means of plural image pickup elements in accordance with the position relation of image spaces before division. SOLUTION: An optical element 1 arranged on the image space-side of a photographing optical system Z divides the image space into plural spaces by polarizing light passing through a prescribed range which is previously set by reflection or refraction. The plane of reflection in the optical element 1 selectively reflects the passing light of the prescribed range, mirrors the left half, does not reflect passing light except for prescribed light on the plane of reflection in the optical element 1 and forms the right half. In the image spaces which are thus divided, structure by a photographing optical system Z partially forms an image. The plural image pickup elements 2a and 2b individually image-pick up the optical images and convert them into image information.  An image synthesis means 3 rearranges image information which are individually picked up based on the position of the image space before division and obtains image information for the whole area of the photographing screen.
