Abstract:
A mounting structure for an inverter circuit board for a light source lamp of an image reader in which mounting means for mounting the inverter circuit board for a light source lamp of an image reader onto a carriage is located to be operated from the direction in which the carriage moves in one embodiment. The inverter circuit and heat dissipation plate are removably mounted to an end of the full rate carriage. In another embodiment, the circuit board is mounted to the top for access from above the carriage.
Abstract:
A position adjustment apparatus couples an imaging unit, which includes an imaging sensor and a focusing lens unit, to a base frame and is capable of adjusting a position of the imaging unit. The image sensor reads a document image and the focusing lens unit forms the document image by using the image sensor. The position adjustment apparatus may include an adjustment frame on which the focusing lens unit and the image sensor are installed, a height fixing member for coupling the adjustment frame to the base frame so as to fix a height of the adjustment frame at a fixed support position, and first and second adjustment members for coupling the adjustment frame to the base frame so as to adjust the height of the adjustment frame at first and second adjustable support positions. An image reading apparatus may include the imaging unit and the position adjustment apparatus.
Abstract:
An image sensor has a supporting member for integrally supporting a reading system including illuminating means for illuminating an original document, a photoelectrically converting means and imaging means for imaging light reflected by the surface of the original document onto the photoelectrically converting means, and has a member disposed on the side surface of the supporting member. The image sensor has two or more substantially independent spaces formed in the supporting member. The illuminating means, the imaging means and the photoelectrically converting means are accommodated in one of the spaces.

Abstract:
An imager (50-1) for imaging a document (12) moving in a document track (14) in a table top document processing machine (10) includes a housing which is made of several portions which are designed to be assembled quickly with a minimum of fasteners. A first line of green LEDs (82-1) and a second line of red LEDs (82-2) are located in the housing to illuminate a scanning line (84) from which image data about the document is obtained by an optical system including a CCD device (100). The imager (50-1) is also designed so that it can be used on either side of the document track (14) to image the front or rear of the document. When two such imagers are used, a white reference member (198) located in one of the imagers is used by the other imager for calibrating the imager to ensure repeatable and uniform data.
