Claims

[Claims for Utility Model Registration] (1) A document is held between a transparent plate and the circumferential surface of a rear roller rotatably disposed via a shaft, and the document is held through the transparent plate. In the reading device in which the reading surface is irradiated with light from a light source and the reflected light from the original is guided to the reading sensor, rollers each having a diameter larger than the circumferential surface of the back roller are provided at both ends of the back roller. By providing and bringing the peripheral surfaces of these rollers into contact with the transparent plate, between the transparent plate and the peripheral surface of the back roller,
A reading device characterized in that a required gap is always ensured. (2) A document is sandwiched between a transparent plate and a circumferential surface of a rear roller rotatably disposed via a shaft, and light from a light source is directed onto the reading surface of the document through the transparent plate. In the reading device, the transparent plate is provided with a spacer member that abuts both ends of the back roller, and the transparent plate and the peripheral surface of the back roller are connected to each other. A reading device characterized in that a required gap is always maintained between the reading device.
