Publication number: 20070091389Abstract: In an automatic original document transport device, there are provided a contact image sensor 10 for scanning an image of an original document 34, and an original document guide member 11 for guiding the original document 34 to the original document scanning surface 13a so as to incline with respect to the original document scanning surface 13a. Therefore, an angle d formed by the optical axis b of the light source 14 and transported original document 34 becomes large, resulting in sufficient radiation of light from the light source 14 to the light source 14. Therefore, when the original document 34 is scanned, an excellent image is obtained, and particularly when a pasted original document is scanned, the problem of a pasted end appearing on the image as a line can be effectively avoided.Type: ApplicationFiled: October 26, 2005Publication date: April 26, 2007Inventor: Masayuki Kakuta

Patent number: 6814353Abstract: An automatic document feeder comprising a reversing device and a discharge device is disclosed. The reversing device and the discharge device are disposed such that the distance in the horizontal direction from an original document reading position in the automatic document feeder to the discharge device is longer than the distance in the horizontal direction from the original document reading position to the reversing device. This configuration allows the use of original documents whose length in the transport direction is short, and also shortens the transport path in the automatic document feeder as well as the amount of time needed to read an original document. Furthermore, this configuration increases the visibility of original documents discharged to the discharge tray by the discharge device because the discharge device is disposed relatively far away from the original document reading position.Type: GrantFiled: April 24, 2003Date of Patent: November 9, 2004Assignee: Kyocera Mita CorporationInventors: Masayuki Kakuta, Hiroyuki Harada, Takuya Eto

Patent number: 6698752Abstract: A projecting tab formed with a bulged portion and an indent on an upper side thereof is provided inwardly projecting in a transport path. A sheet being transported in the transport path is formed into a seemingly wavy configuration in the width direction of the transport path while in contact with the projecting tab. The sheet thus formed with the seemingly wavy configuration is given with a sufficient transport backup force in a transport direction, thereby being hard to bend in the transport direction. Thus, the sheet supplied with the sufficient transport backup force is free from a curled lead end, folded or bent corner lead end of the sheet in the transport direction, and sheet jam. The arrangement of the projecting tab securely accomplishes sheet transport in a desired transport direction without a possibility of sheet transport failure.Type: GrantFiled: March 13, 2000Date of Patent: March 2, 2004Assignee: Kyocera MITA CorporationInventors: Masayuki Kakuta, Masaki Degichi, Kuniaki Araishi, Kazuyoshi Osawa, Yutaka Aso, Hideki Kitagawa

Patent number: 6209861Abstract: A sheet transport device is provided with a sheet inverting mechanism for retracting a sheet transported along a main transport route into a switchback route to invert the sheet transport direction and returning the sheet into the main transport route to turn the side of the sheet. The sheet transport device has a pair of sheet guides adapted in contact with respective opposite ends of the sheet set on a sheet setting portion to prevent a skew transport of the sheet. The sheet temporarily brought onto the sheet setting portion during a switchback operation from the switchback route is guided between of the sheet guides on the sheet setting portion. During the temporal appearance on the sheet setting portion, the opposite ends of the sheet are aligned by the respective sheet guides. Thereby, securely prevented is an occurrence of a skew transport state of the sheet during the switchback operation.Type: GrantFiled: March 8, 1999Date of Patent: April 3, 2001Assignee: Kyocera Mita CorporationInventors: Masayuki Kakuta, Masaki Deguchi, Hiroshi Kobayashi, Jun Kusakabe, Yutaka Aso, Kuniaki Araishi, Shigeo Kurando

Patent number: 6206368Abstract: In a paper transport device, a first roller serving as a separation roller is situated underneath a second roller serving as a document feed roller, together forming a roller pair. A rotary shaft of the separation roller is biased upward toward the document feed roller by means of an elastic element. One end of the rotary shaft is connected to a drive shaft via a coupler while a connecting bar is joined to the other end of the rotary shaft obliquely from above. An extreme end of the connecting bar opposite to the rotary shaft is attached to a support plate fixed to a main body of the paper transport device in such a way that the connecting bar can swing about pivot pin fixed to the support plate. In the paper transport device thus constructed, one end of the rotary shaft fitted to the coupler acts as a point of support, allowing the other end of the rotary shaft to move downward overwhelming an upward-lifting force of the elastic element when forced downward by the connecting bar.Type: GrantFiled: March 8, 1999Date of Patent: March 27, 2001Assignee: Kyocera Mita CorporationInventors: Hiroshi Kobayashi, Masayuki Kakuta, Jun Kusakabe, Masaki Deguchi, Yutaka Aso, Kuniaki Araishi, Shigeo Kurando

Patent number: 6161831Abstract: A sheet transport device is provided with a sheet inverting mechanism for performing a switchback operation in which a sheet transported along a main transport route enters a switchback route, and the sheet transport direction is inverted in the switchback route to return the sheet to the main transport route so as to turn the side of the sheet. A registration roller pair is disposed near the junction between the main transport route and the switchback route. The sheet inverting mechanism is operated in such a manner that the sheet transport is temporarily suspended until a skew correctable portion that enables correction of a skew transport state of the sheet is formed at a lead end of the sheet in the exiting direction from the switchback route after the lead end of the sheet comes into contact with the registration roller pair. Thus, the skew transport state of the sheet which is liable to occur during the switchback operation is corrected.Type: GrantFiled: March 8, 1999Date of Patent: December 19, 2000Assignee: Kyocera Mita CorporationInventors: Jun Kusakabe, Masayuki Kakuta, Hiroshi Kobayashi, Masaki Deguchi, Yutaka Aso, Kuniaki Araishi, Shigeo Kurando

Patent number: 5879000Abstract: An automatic document conveying device comprises a document table on which documents are placed; a vacuum separating/feeding means for feeding the set documents placed on the document table; a set document stopper for positioning the front ends of the documents placed on the document table; and a discharged document stopper for restraining the movement of the document discharged onto the set documents after being fed by the vacuum feeding means and subjected to image processing. A first opening and a second opening are provided in the document table. The vacuum separating/feeding means is disposed below the first opening. A feed drum connected to the vacuum chamber of the vacuum separating/feeding means via an opening/closing means is disposed below the second opening.Type: GrantFiled: April 23, 1998Date of Patent: March 9, 1999Assignee: Mita Industrial Co., Ltd.Inventor: Masayuki Kakuta
