Claims

[Claims for Utility Model Registration] (1) A document table having a reading section, a reading optical system that forms an image of light from the surface of the document incident through the reading section, and a reading optical system arranged at an image forming position of the reading optical system. An image reading device main body including a line sensor for reading an original image; a light source; a film feeding mechanism that feeds the film in front of the light source in a sub-scanning direction perpendicular to the reading line direction that is the main scanning direction; a magnifying projection device including a projection optical system that magnifies and projects an image; and the image reading device main body and the magnifying projection device are arranged so that the reading optical system and the projection optical system coincide with each other. An image reading device characterized in that: (2) A document table having a reading section, a reading optical system that forms an image of light from the surface of the document that has entered through the reading section, and a line sensor that is arranged at the image formation position of the reading optical system and reads the document image. an image reading device main body, a light source, a film feeding mechanism that feeds the film in front of the light source in a sub-scanning direction perpendicular to a reading line direction that is a main scanning direction, and a main body disposed facing the document table. An image reading device comprising an enlargement projection device including a transmissive screen elongated in the scanning direction and a projection optical system for enlarging a film image and projecting the enlarged film image onto the transmissive screen. (3) Claim 1 characterized in that the lenses constituting the projection optical system are provided movably in the optical path direction.
or the image reading device according to 2. (4) The image reading device according to claim 1 or 2, wherein the film feeding mechanism feeds the film in the sub-scanning direction in synchronization with the reading speed of the line sensor.
