とを特徴とするシートスキヤナ装置。 In a sheet scanner device that scans a moving sheet document by focusing it on a one-dimensional sensor array through an optical system from a slit-shaped reading section installed at a fixed position, a transparent document pressure plate is provided at a position on the back side of the document of the reading slit. The top surface of this mirror is a strip mirror formed of a reflective film, and a mirror that guides the reflected light from the document to the sensor array is arranged at a position opposite to the document reading side, and the relative inclination angle of the strip mirror and the mirror is determined by A sheet scanner device characterized in that the irradiation light from a longitudinal light source for illumination is set so that substantially all of the light is incident on a light sensor array.
