Patent number: 7224495Abstract: An image reading unit includes an image sensor for converting light from a document into an electric signal, and a circuit board provided with the image sensor on one side. In the image reading unit, a heat dissipating member for controlling a temperature of the image sensor is attached to one side of the circuit board, and a shield member for reducing a noise is provided on the other side of the circuit board. The heat dissipating member and the shield member are connected by a heat conductive member. Also, the heat dissipating member is interposed between the image sensor and the circuit board.Type: GrantFiled: May 14, 2002Date of Patent: May 29, 2007Assignee: Nisca CorporationInventors: Kenichi Yui, Osamu Sumiya

Patent number: 7123389Abstract: An image reading unit includes a light source for illuminating a document, a plurality of reflecting devices for reflecting the light from the document, a condensing device for condensing the light reflected by the reflecting devices, and a reading device disposed at a condensing position at a rear side of the condensing device. The light source is disposed at a forward side of the condensing device. A plurality of reflecting devices includes a final reflecting device and a reciprocating reflecting device. The final reflecting device forms a linear optical path together with the reading device, and the reciprocating reflecting device forms at least one reciprocating optical path crossing the linear optical path between the condensing device and the reading device. Accordingly, the image reading unit can be made small.Type: GrantFiled: May 14, 2002Date of Patent: October 17, 2006Assignee: Nisca CorporationInventor: Kenichi Yui

Patent number: 7051941Abstract: An image reading apparatus includes a scanning unit disposed in a box-shaped casing for scanning a stationary original in a sub-scanning direction to read the original; a supporting unit for supporting one side of the scanning unit in a main scanning direction and guiding the one side of the scanning unit in the sub-scanning direction; a driving source for moving the scanning unit in the sub-scanning direction; a drive transmitting unit for transmitting a drive of the driving source to the scanning unit; and first and second reinforcing plates attached to the casing along the sub-scanning direction for reinforcing the casing. The first reinforcing plate forms a guide unit for supporting the other side of the scanning unit in the main scanning direction and guiding the scanning unit in the sub-scanning direction. The driving source and the drive transmitting unit are fixed to the second reinforcing unit.Type: GrantFiled: March 2, 2004Date of Patent: May 30, 2006Assignee: Nisca CorporationInventor: Kenichi Yui

Patent number: 6513806Abstract: A recording device for recording information data such as images and characters on a recording card has one or more card transfer paths intersecting with a first transfer path extending from a card supply means at one or more intersection points. At the intersection point, there is placed a card turning means for turning the card or transferring the card between the card transfer paths. The technically ingenious arrangement of the card transfer paths and the card turning means enables materialization of making the compact, high-performance recording device capable of handling and processing the card effectively and producing various types of information cards such as credit card, license card and IC card with high efficiency.Type: GrantFiled: March 13, 2001Date of Patent: February 4, 2003Assignee: Nisca CorporationInventor: Kenichi Yui
