Inventor: KIDA NORIHIKO
IPC: B65H7/18
Filed: 1992-09-24
Abstract: PURPOSE:To improve the operability and image forming efficiency by providing a control means which performs control such that when a paper sheet is not conveyed to a paper detecting means within a specified time, an image forming means is caused to effect racing operation at a continuous image formation period, and when the paper sheet is conveyed thereto at a subsequent cycle, image forming operation is continued. CONSTITUTION:Through rotation of register rollers 136, 137, and 138, a paper sheet P in a paper conveyance passage 40 is conveyed. A control part decides it by means a paper stop switch whether the forward end of the paper sheet P is conveyed to a register roller pair 37. In this case, when the paper stop switch 48 is not turned ON even when a given time elapses, the control part decides that a jam occurs at a first copying period. When a timing of arrival to the paper stop switch 48, namely a distance between paper sheets is long, an electronic photographic copying device 1 is caused to effect racing operation and effect coping operation at a next cycle. Thus, even when the feed of paper sheets is delayed owing to the slip of a roller, it is not decided that a paper feed miss occurs but normal copying can be carried out.

Title: Color ink jet recording method
Inventor: YAJI MASAO
IPC: B41J2/21
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To occur no contact between the inks of respective color regions adjacent to each other even when the inks effuse and no lowering of image quality results. SOLUTION: On the basis of original image data, the contours of color regions AR 16 and AR 17 are extracted. On the basis of the extracted contour data, whether the color regions AR 16 and AR 17 are adjacent to each other or not is judged. When the color regions AR 16 and AR 17 are judged to be adjacent to each other, the pixels D1 and D2 adjacent to the color regions AR 16 and AR 17 are made smaller than other pixels. In this case, since no contact between the inks effused from the adjacent parts of the respective color regions AR 16 and AR 17 occurs, an image quality can be improved. Further, since no thinning of the pixels D1 and D2 adjacent to the color regions occurs, the faithful reproduction of an original image becomes possible and the lowering of an image quality can be prevented from occurring.
