Contact type image sensor and information processing apparatus
First Claim
1. A contact type image sensor comprising:
- (a) a transparent substrate having photosensors mounted thereon;
(b) a focusing unit, disposed on said transparent substrate on a side opposite to a side where the photosensors are mounted, for focusing light from an original upon the photosensors; and
(c) a frame for holding said transparent substrate and said focusing unit, wherein said transparent substrate has a light shielding layer and is not covered with the light shielding layer in an area corresponding to a focusing area of said focusing unit.

Abstract
In a contact type image sensor having a sensor array mounting photosensors, a focussing unit for focussing light from an original upon the photosensors, and a frame for holding in position the sensor-array and focussing unit, the focussing unit abuts on the sensor array. In a contact type image sensor having a sensor array having a plurality of face-down sensor chips with a plurality of pixels mounted on a transparent substrate in line, a rod lens array for focussing light from an original, a light source for illuminating the original, and a frame for holding in position the sensor array, rod lens array, the transparent substrate is covered with a light shielding layer in an area other than an area on which the pixels of the sensor chips are mounted and an area corresponding to a focussing area of the rod lens array.

10. A contact type image sensor comprising:
-
(a) photosensors;
(b) a support member for supporting an original;
(c) a focusing unit for focusing light from the original upon the photosensors;
(d) a frame for holding said photosensors, said focusing unit, and said support member; and
(e) a focusing unit holding member different from said support member and disposed between said support member and said focusing unit, for positioning said focusing unit relative to said frame in an optical path direction of said focusing unit and wherein a thickness in the optical path direction of said focusing unit holding member between said support member and said focusing unit is set so that an original support surface of said support member is positioned in a range of a depth of focus of said focusing unit, and said focusing unit holding member abuts on said support member and said focusing unit. - View Dependent Claims (11, 12, 13, 14)
