    摘要: A contact image sensor comprises a housing, a light source provided on the upper part of the housing to irradiate light to a document, lenses arranged in the housing and provided at least on an entering side and an outgoing side to focus reflected light from a reading position of the document, an aperture angle regulation member having an inclined surface to reflect a part of light irradiated from the light source at the reading position of the document and an aperture portion into which the reflected light enters directly to regulate an aperture angle to permit the reflected light passing through the aperture portion to be irradiated to the lens on the entering side, and a light receiving element array to receive and photoelectrically convert the reflected light focused after passing through the lenses.

    摘要: According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The photoelectric conversion element outputs an electric signal obtained by converting the light from the detection position of the document. The light-emission controller changes the light quantity of the light emitted by the light-emitting element. The detection processor detects the presence or absence of the document at the detection position of the document based on the presence or absence of a change of an output value corresponding to the change of the light quantity caused by the light-emission controller in an output value from the photoelectric conversion element.
