Patent number: 5257064Abstract: In a copying machine provided with a recirculating document feeding apparatus (RDH), the time required for the overall copying operation is reduced. In the copying machine provided with the RDH, there are cases where the copying operation is started after the number of the documents is counted. Maximum transporting speed of the document in the copying operation is a speed determined in accordance with minimum copying magnification. However, since the transporting speed of the document be set higher than the speed determined in accordance with the minimum copying magnification, the time required for the counting operation can be reduced. Thereby, the time required for the overall copying operation can be reduced.Type: GrantFiled: August 25, 1992Date of Patent: October 26, 1993Assignee: Sharp Kabushiki KaishaInventor: Yuji Okamoto

Patent number: 5253012Abstract: A substrate holding apparatus for vertically holding a substrate to be exposed by radiation includes a substrate holding member for attracting a substrate by a magnetic force or vacuum and an engaging device for engaging the substrate on the substrate holding member. The engaging device is retractably supported by or fixed to the substrate holding member, and is engageable with or engages the substrate in such a manner that the engagement between the vertically held substrate and the engaging device is maintained even if the substrate holding member ceases to attract the substrate. Thus, dropping of the substrate by gravitation is prevented even if the substrate ceases to be attracted by the substrate holding member.Type: GrantFiled: October 2, 1991Date of Patent: October 12, 1993Assignee: Canon Kabushiki KaishaInventors: Yuji Chiba, Hidehiko Fujioka

Patent number: 5253011Abstract: A strip of exposed and developed film has a series of exposures and corresponding exposure identification numbers. The strip is conveyed through a scanning station on its way to a printing station. The exposures and identification numbers are scanned in the scanning station to produce output signals indicative of density changes. The signals are processed to generate groups of data which are combined into a data set. Each group includes the position of a respective exposure on the strip, the identification number for the exposure and the position of the identification number on the strip. Film transport is carried out in such a manner that scanning of the strip and processing of the resulting signals are completed before arrival of the strip at the printing station. A control unit uses the data set to position the exposures in the printing station and to print the exposures. The control unit also uses the data set to mark a copy of an exposure with the identification number of the exposure.Type: GrantFiled: February 11, 1992Date of Patent: October 12, 1993Assignee: AGFA-Gevaert AktiengesellschaftInventors: Wolfgang Zahn, Wilhelm Nitsch, Gunther Schnall, Gerhard Benker

Patent number: 5250980Abstract: The improved slit scanning exposure apparatus has a variable slit assembly that is provided in proximity with the exposing zone and which is composed of two slit plates movable independently of each other in synchronism with the scanning speed. The apparatus may additionally have a color filter that can be inserted into the optical path of reflected light from the image on a document in the scanning direction. The apparatus is capable of preventing flare from being admitted through an exposure slit to a light-sensitive material on the exposure position when it is being exposed from light reflected from the document image. In addition, the apparatus enables more than one document image to be edited into a single image and permits the color filter to be inserted into the optical path of reflected light without causing unevenness in colors.Type: GrantFiled: November 13, 1991Date of Patent: October 5, 1993Assignee: Fuji Photo Film Co., Ltd.Inventors: Minoru Yakubo, Ryoichi Kato

Patent number: 5235382Abstract: Apparatus for providing a background having a desired color and/or pattern on photocopies made of bulky objects comprises a cover for placement between a platen of a photocopy machine and a bulky object, such as a book, to be photocopied. In the preferred embodiment, the cover comprises a clear, transparent, flexible envelope filled with a white liquid. The cover is placed on a platen of a photocopy machine, and a book to be photocopied is placed face-down on the cover. The weight of the book, or pressure applied on the book, forces the white liquid out of the area between the pages of the book to be photocopied and the platen, allowing the photocopy machine to "see" the page or pages to be photocopied against a white background. A photocopy reproduces the page on a white background, instead of the black background which is usually present in a photocopy, made without the cover, of a page of a book.Type: GrantFiled: January 26, 1988Date of Patent: August 10, 1993Inventor: Seth M. Nehrbass
