Abstract: An electronic filing apparatus files documents employing an optically readable mark sheet. A scanner reads a set of data sheets including the mark sheet and original sheets. The mark sheet sets reading conditions for scanning the original sheets in the scanner according to marks on the mark sheet. Original image data on the original sheets is read based on the set reading conditions and filed in a storage device. For filing small amounts of information, both control mark and original image information may be included on a single sheet. The mark sheet may include marks representing search terms descriptive of the content of the original image data which can be used by an operator to search the electronically registered and filed documents.

Abstract: An image rotating device is described which includes a storage unit for storing image information and a tilt indicating unit for imputting information necessary to corect the tilt of the image information stored in the storage unit. Further, an image processing unit devides the image information, stored in the storage unit, into a plurality of areas according to the information supplied by the tilt indicating unit. It then affects a parallel movement of each area to accomplish the correction of the tilt of the image information.

Abstract: A display system includes a memory device, a central processing unit, a converting circuit and a display device. The memory device is for sequentially storing image data at addresses corresponding to positions in line and column directions of an original image to be displayed. The central processing unit controls the overall operation of the system and also retrieves the image data selectably either from every line or every Mth line. The converting circuit sequentially and temporarily stores the retrieved image data by extracting selectably either every bit or every Nth bit of the retrieved image data sequentially, M and N being integers greater than 1. These serial data formed by the converting circuit are displayed by the display device.
