Gapless support system for contact type image sensor
CA 2098043 A1
Abstract
A contact type image sensor comprises a transparent member which can contact an original such as a document to be read, a light source for radiating light onto the original via the transparent member, a sensor for receiving light reflected by the original, an imaging element for imaging the reflected light on a light-receiving portion of the sensor, and support unit for supporting the sensor, the imaging element, the transparent member, and the light source. At least one of the imaging element and the light source is supported by the transparent member and the support unit. Preferably, the transparent member and the imaging element are supported in a tight contact state without forming a gap between them.
