Overhead image reading apparatus

Abstract

The overhead image reading apparatus includes a line sensor 20 which has light receiving elements arranged one-dimensionally to read the image of a document 75 in a one-dimensional direction, a white LED 26 which emits light, a collimator lens 28 which converts light emitted from the white LED to straight-line light, a diffuser plate 29 which converts light converted to straight-line light by the collimator lens to linear irradiation light 90, and line light source units 25 which irradiate linear irradiation light onto a reading region of an image by the line sensor. Moreover, the apparatus includes a rotary head section 5 which holds the line sensor and the line light source units as a single body and rotates the line sensor and the line light source units as a single body when the line sensor reads the image.
