In the image read device, the thicknesses of the second and third mirror elements may be different from each other. Further, the thickness of the first mirror element may be larger than the width of the reflecting surface of the first mirror element as viewed in the slow scan direction.

Abstract: A scan guide upon image reading by an image reading apparatus having a driving mechanism constructed by a rack and a pinion gear is stably performed. The pinion gear is provided on a downstream side of two contact portions which are in contact with a guide rail of the reading scan. A straight line drawn in a pressure angle direction from a contact point of the rack and the pinion gear upon reading and scanning passes between the two contact portions with the guide rail, so that a stable positional relation between a driving force of the gear and the contact portions is obtained. The stable guiding can be performed.

Abstract: A combination of an optical module and a transmitting and carrying structure includes an optical module, at least one carrying seat, and two rollers. The at least one carrying seat is combined with the optical module, for mounting the two rollers. The two rollers are located at the two opposite sides of the optical module. The two opposite sides of the optical module are perpendicular to the movement direction of the optical module. Thus, the at least one carrying seat and the two rollers are used to support and transmit the optical module, so that the optical module may be well balanced. In addition, the assembly height and the cost of fabrication are reduced.

Abstract: When the speed of carriages that are moved in an image processing device is increased in order to accelerate the processing speed, the acquired image data is degraded due to vibrations being transmitted to the carriages from a motor which drives the carriages. The present invention provides a vibration damping mechanism for such image processing devices wherein weights are provided at selected positions on the transmission paths of the vibrations from the motor to the carriages in order to damp the vibrations. Preferably, the weights are made of a permanent magnet material and the housing is made of a material, such as steel, that is attracted by a magnet. This enables the weights to be attached at any desired positions, such as on the housing base plate, on the lower housing, and at perimeter walls of the housing which support the carriages where vibrations, without the weights, would be excessive.
