Patent number: 6288768Abstract: An image reading device capable of reading images on the both surfaces of a document in order while moving the document at a prescribed speed includes a platen for reading the document moving at the prescribed speed, a reversible transferring device for moving the document at the prescribed speed along the platen, and a circulating passage for turning the document and sending back to the platen after reading the image on the obverse surface of the document. The circulating passage is composed of at least first and second turning paths for inverting a direction in which the document is transferred to turn the document upside down, so that the images on the obverse and reverse surfaces of the document can be continuously read with a compact mechanism and starting to scan from the same end of the document whenever the document is read.Type: GrantFiled: January 20, 1999Date of Patent: September 11, 2001Inventors: Hayato Ichinose, Shuji Ishimaru

Patent number: 5926681Abstract: A document feeding device mounted on an image processing device such as a copying machine for automatically feeding duplex original documents having images to be read on both sides to an image reading point one by one in such a manner that the document fed from a supply tray is reversed at a switchback part, sent through the image reading point to read the image on one side thereof, sent back to the switchback part to be turned upside down, again sent through the image reading point to read the image on the other side thereof, and then, discharged to a discharge tray. The documents can be rationally transported at high speed with high efficiency, and consecutively discharged to the discharge tray in the same order of page as those initially set on the supply tray.Type: GrantFiled: June 10, 1997Date of Patent: July 20, 1999Assignee: Nisce CorporationInventor: Shuji Ishimaru

Patent number: 5887865Abstract: According to a document feeder for an image-forming apparatus of the present invention, when a double-sided document fed from a feed paper stacker, the document with the front surface thereof having been read out by a document reader unit is inverted in a switch-back path provided between the document reader unit and a discharged paper stacker on which documents after having been read out will be stacked, and is conveyed again to the paper reader unit so that the back surface is read out. The document after its both surfaces have been read out is again inverted in the switch-back path and then discharged onto the discharged paper stacker. With such a construction, the documents after having been read out can be stacked in the order of sequence of pages of the documents. Furthermore, the size of the device can be decreased, contributing to shortening the time required for reading the double-sided document and to increasing the efficiency for forming images.Type: GrantFiled: June 3, 1997Date of Patent: March 30, 1999Assignees: Konica Corporation, Nisca CorporationInventor: Shuji Ishimaru

Patent number: 5601281Abstract: A document feed roller and registering rollers are driven through first and second one-way clutches so that the feed roller connected to the motor through the first one-way clutch is driven to forward a document to be processed only when the motor rotates in a positive direction, and the registering rollers connected to the motor through the second one-way clutch are driven to perform skew-correction and forward the document only when the motor rotates in a negative direction. The document is transported for a first part of a document feeding passage by the feed roller and for a second part of the passage by the registering rollers with efficiency merely by switching the rotational direction of the motor.Type: GrantFiled: December 29, 1994Date of Patent: February 11, 1997Assignee: NISCA CorporationInventors: Toshihiro Kubodera, Shuji Ishimaru
