Abstract
A contact type image sensor, which includes a transparent member which can contact an original 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 a support unit for supporting the sensor, the imaging element, the transparent member, and the light source. The imaging element and the light source are supported by the transparent member and the support unit.
Claims27
A contact type image sensor, comprising:
- a transparent member which can contact an original to be read;
- a light source for radiating light onto the original via said 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 said sensor;
- and
- support means for supporting said sensor, said imaging element, said transparent member, and said light source,
- wherein said imaging element and said light source are supported by said transparent member and said support means.
An information processing apparatus comprising:
- a contact type image sensor comprising:
- a transparent member which can contact an original to be read;
- a light source for radiating light onto the original via said 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 said sensor;
- and
- support means for supporting said sensor, said imaging element, said transparent member, and said light source, wherein said imaging element and said light source are supported by said transparent member and said support means;
- and
- means for supporting an original on an original reading surface of said sensor.
A contact type image sensor, which comprises a support member for supporting a sensor array for performing photoelectric conversion, an imaging element for imaging light reflected by an original on said sensor array, a transparent member for defining a reading surface of the original, and a light source for illuminating the original,
- wherein said support member has a first support member having positioning portions for determining positions of said light source, said imaging element, and said sensor array, and a second support member having two opposing portions extending in a longitudinal direction of said support member, and a crossing portion crossing said opposing portions,
- said second support member clamping said imaging element by said opposing portions via said first support member,
- said first support member and said sensor array being clamped between said transparent member and said crossing portion, and
- said opposing portions clamp said transparent member.
A contact type image sensor comprising:
- a support member for supporting a sensor array for performing photoelectric conversion;
