Patent number: 6707565Abstract: An image output system having an image output device for performing a specified output process with respect to image data, and an image input device for providing the image data via reading an image from a document, or via an external device. Both the image input device and image output device have controllers for controlling the respective devices. The controller of the image output device outputs a reset signal to the system controller of the image input device when a response from the controller of the image input device is not appropriate, and continues to output the reset signal until a predetermined time elapses and the response from the controller of the image input device is judged to be appropriate.Type: GrantFiled: October 29, 1998Date of Patent: March 16, 2004Assignee: Minolta Co., Ltd.Inventors: Tadashi Ohira, Toshikazu Kawaguchi, Hideyuki Kanbayashi, Tsutomu Yamazaki

Patent number: 6594039Abstract: The present invention provides an image reading device and image reading method which reduce the total reading time and do not produce color drift when reading a plurality of documents comprising a mix of color and monochrome documents. The present invention provides for reading all documents by moving the documents during reading past a fixed position reader. If the documents are determined to be color documents, the documents are read by moving the reader during reading past fixed position documents. The present invention also provides an image forming apparatus, which reduces the total reading time when reading a mix of color and monochrome documents. The present invention additionally provides a computer program product for use in an image reading system to operate the system in the prescribed manner.Type: GrantFiled: April 21, 2000Date of Patent: July 15, 2003Assignee: Minolta Co., Ltd.Inventor: Hideyuki Kanbayashi

Publication number: 20020075503Abstract: In a printer-copiers system of an office area (“OA”) network, an automatic document feeder (ADF) is used in an image output device which selectively outputs the image read from the document or received from an external device (for printing or facsimile transmission). If some trouble occurs during the reading of a document and disables the read operation, the conventional image output device is brought into a substantially non-operating state (system down), when viewed from the external device, and remains therein till the trouble is removed and the read operation is enabled. Unless the user promptly takes the proper measures, not only the copy job but also the print job stagnates. It is therefore an object of the present invention to minimize the duration of a period during which the read operation is disabled by promptly canceling the hang-up of the processor for controlling the reading of the document.Type: ApplicationFiled: October 29, 1998Publication date: June 20, 2002Inventors: TADASHI OHIRA, TOSHIKAZU KAWAGUCHI, HIDEYUKI KANBAYASHI, TSUTOMU YAMAZAKI

Patent number: 6400466Abstract: A copying system consisting of a scanner and a printer which are directly connected, including a printer controller controlling a printer engine based on data received from an external computer via a network line, an interface switching unit switching the occupancy of the printer engine between the printer controller and the scanner, and a controller that makes the printer controller occupy the printer engine by means of controlling the interface switching unit when a trouble occurs while the printer engine is occupied by the scanner.Type: GrantFiled: September 30, 1998Date of Patent: June 4, 2002Assignee: Minolta Co., Ltd.Inventors: Tsutomu Yamazaki, Hideyuki Kanbayashi, Toshikazu Kawaguchi, Tadashi Ohira

Patent number: 6002429Abstract: An image sensing device that provides image data to an external device adjusts the resolution at which the image is sensed in accordance with format requirements of the external device. The format requirements of the external device can be automatically detected, or entered by a user. The operating parameters of a line sensor, to scan the image in a subscanning direction, are varied in accordance with the format requirements. These operating parameters can be the integration cycle of the sensor, and/or the speed at which the image is optically scanned past the sensor.Type: GrantFiled: May 23, 1996Date of Patent: December 14, 1999Assignee: Minolta Co., Ltd.Inventors: Keizou Ochi, Takashi Iida, Hideyuki Kanbayashi, Takashi Kondo

Patent number: 5134444Abstract: An image forming apparatus which develops two latent images formed on a photoreceptor with developing agents respectively containing first and second toners of different colors, and is so constructed that, a clear image is obtained by processing mixed-color separation to restrain the mixed-color as much as possible, in response to respective consumptions of a first toner and a second toner, or every time a fixed amount of first toner is consumed, and further, in response to the amount of first toner mixed into a second developing agent detected when a fixed amount of first toner is consumed.Type: GrantFiled: May 14, 1991Date of Patent: July 28, 1992Assignee: Minolta Camera Kabushiki KaishaInventors: Kenji Tabuchi, Tateki Oka, Hideyuki Kanbayashi

Patent number: 4891670Abstract: A copying machine in which copying magnification can be changed comprises a slide lever for selecting an arbitrary copying magnification and a CPU for calculating the copying magnification based on the amount of travel of the slide lever, wherein the CPU controls the copying machine such that the copying operation is carried out at desired prescribed magnification rates regardless of the set position of the slide lever in the equal scale magnification region and in prescribed magnification copying regions which are frequently used and that the copying operation is carried out at a magnification rate corresponding to the set position of the slide lever in particular magnification set regions other than the above described regions.Type: GrantFiled: June 24, 1988Date of Patent: January 2, 1990Assignee: Minolta Camera Kabushiki KaishaInventor: Hideyuki Kanbayashi

Patent number: 4796065Abstract: An apparatus for detecting image density in an image forming machine includes a first sensor for receiving mainly a regular reflecting light reflected from a reference toner image, and a second sensor for receiving mainly scattered reflecting light reflected from the reference toner image. The output signals from each sensor are compared with each other so as to produce a differential signal. Upon presetting the difference signal to be nil for a predetermined image density, an increase or a decrease of the reference toner image will invite a change of plus/minus sign of the differential signal.Type: GrantFiled: March 6, 1987Date of Patent: January 3, 1989Assignee: Minolta Camera Kabushiki KaishaInventor: Hideyuki Kanbayashi
