Publication number: 20100156038Abstract: The present invention provides an apparatus for maintaining surface smoothness of note as they pass through a high speed processing machine. A note fed into the processing machine is carried through the machine by a series of conveyor belts. The note is conveyed past a line scan camera that records the note as it crosses a gap while passing from a first conveyor belt to a second conveyor belt that is approximately orthogonal to the first conveyor belt. A curved note guide redirects the path of the note as it crosses the gap between the conveyor belts. The inertia of the note causes it to remain flush against the surface of the curved guide, allowing the line scan camera to record each line of the surface of the note with equal resolution.Type: ApplicationFiled: March 9, 2010Publication date: June 24, 2010Inventors: Jerry Edwards, Bruce Blair

Publication number: 20090267291Abstract: A sheet transport switching device include a rotary guide that is pivotal about an axis orthogonal to a sheet transport direction to align a guide passage with one of two discharge destinations. A stepping motor changes the posture of the rotary guide and a controller controls the stepping motor. A lead end in-timing acquirer acquires a timing when a lead end of the sheet enters the guide passage. The controller performs, in a state that the exit of the guide passage aligns with one of the two discharge destinations, an in-timing retaining operation of retaining a rotated position of the stepping motor by supplying an energizing current of a first current value to the stepping motor at the acquired lead end in-timing, and a pass timing retaining operation of reducing the energizing current to a second value when the lead end of the sheet passes the guide passage.Type: ApplicationFiled: April 14, 2009Publication date: October 29, 2009Applicant: Kyocera Mita CorporationInventor: Fujio TABATA

Patent number: 7597320Abstract: A switchback unit has a switchback roller which receives a paper sheet conveyed in a first direction into a nip for forward rotation and backwardly rotates the paper sheet after stopping the paper sheet to feed the paper sheet to a second conveyance path. When the conveyance of the paper sheet stopped on the way to the switchback section is resumed, control is performed so that the switchback roller is forwardly rotated until a sensor detects the tip of the paper sheet, and then the switchback roller is stopped and backwardly rotated.Type: GrantFiled: March 17, 2006Date of Patent: October 6, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Yuji Matsumoto, Yukio Asari, Yoshihiko Naruoka

Publication number: 20090243199Abstract: A sheet transport direction switching device includes: a rotary guide member having a single guide passage for passing a sheet to be transported, and a support shaft extending in a direction orthogonal to a transport direction of the sheet; and a posture changing mechanism for changing the posture of the rotary guide member. The rotary guide member is operable to change the posture thereof by pivotal movement about an axis of the support shaft so that an exit of the guide passage faces one of at least two discharge destinations. The posture changing mechanism has a stepping motor for pivotally moving the rotary guide member about the axis of the support shaft.Type: ApplicationFiled: March 25, 2009Publication date: October 1, 2009Applicant: Kyocera Mita CorporationInventors: Hironori Daigo, Chisato Hatakeyama

Publication number: 20090224458Abstract: A technique in an image forming apparatus in which the front and back sides of a sheet are reversed by using a reversal conveyance path is provided for causing the sheet to wait such that the sheet is not damaged when a unit for conveying the sheet to the reversal conveyance path is pulled out for the purpose of clearing a jam or the like. A roller for conveying the sheet is controlled such that the sheet to be turned back and directed into the reversal conveyance path is caused to wait until the sheet can be conveyed into the reversal conveyance path. As a standby position of the sheet while the sheet is caused to wait, a position is set such that an upstream end portion in the second conveying direction of the sheet to be directed into the reversal conveyance path does not extend for a predetermined length or longer into another conveyance unit adjacent to the intermediate conveyance unit upstream from the intermediate conveyance unit in the second conveying direction.Type: ApplicationFiled: March 6, 2009Publication date: September 10, 2009Applicants: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Masataka MURATANI, Kazumasa Yasui, Masaya Arakawa
