READING MODULE, IMAGE READING DEVICE COMPRISING SAME, AND IMAGE FORMING DEVICE

WIPO Patent Application WO/2018/100820

A1

A reading module (50) comprising: a light source (31) that irradiates a document (60); an optical system (40) that comprises a mirror array (35) and a diaphragm (37) and forms an image using, as image light, reflected light from the light irradiated on to the document (60) from the light source (31); a sensor (41) having arranged therein a plurality of image-forming areas (41a, 41b) that convert the image light formed into an image by the optical system (40), into electric signals; a case (30); and a light-shielding wall (43) that blocks stray light incident to each image-forming area (41a, 41b). The mirror array (35) has a plurality of reflective mirrors (35a–35c) that have aspherical recessed reflective surfaces and are coupled in an array shape in a main scanning direction. The optical system (40) is fixed to the case (30) at one point in the main scanning direction and each light-shielding wall (34) is arranged at a position displaced by a prescribed amount from the boundary of each image-forming area (41a, 41b) in the opposite direction to the side on which the optical system (40) is fixed.
