    Abstract: A scanning apparatus includes a sheet holder for holding a sheet to be scanned in the shape of a segment of a cylinder, a light source for irradiating the sheet with light, a spinner including a converging lens for converging light from the light source on the surface of the sheet, and a light detector for photoelectrically detecting light from the sheet, a spindle motor including a plurality of rolling balls in a bearing for rotating the spinner coaxially with a center axis of the cylinder, and a sub-scanning device for moving the sheet holder relative to the spinner in a direction parallel to the center axis, and the rolling balls are provided so that the vibrational frequency F of the bearing satisfies the formula Fb/6.ltoreq..vertline.F-n1.times.Fb.vertline..ltoreq.Fb/2 wherein Fb is the rotational frequency of the spindle motor and n1 is a positive integer. According to the thus constituted scanning apparatus, it is possible to read an image which contain no visibly recognizable wave-like unevenness even when the image is read at high density at a reduced scanning pitch.

    Abstract: An imaging module mounting apparatus is provided to improve dynamic performance without creating an overconstraint condition causing misalignment of the imaging module. Three solid mounts are used to establish and maintain critical location datums of the imaging module. A single or plurality of variably flexible mounts are used, depending on the size of the module, to maintain alignment while minimizing any overconstraint condition caused by the imaging module being distorted out of plane due to thermal distortion and/or static distortion of the mounting frame due to movement of the machine. The variably flexible mount is filled with a high-viscosity silicon polymer. Due to the high-viscosity of the medium, the mount does not respond to fast or high-frequency vibration and appears to be a rigid mount with regard to such movement. The mount will react to very low frequency or static distortion such as that caused by movement of the machine and/or thermal distortion and maintain the imaging module in the proper position to prevent perceptible image defects.

    Abstract: A laser imaging apparatus, such as a laser scanner or laser printer, includes a gas or diode laser which produces a laser beam and an optical system for directing the laser beam onto a object to be scanned or printed. The laser beam is encompassed in a sealed housing from the laser's output to a point at which the beam is no longer subjected to turbulent environment in order to eliminate laser beam pointing instabilities resulting from a turbulent environment caused by thermal sources, cooling fans, etc.
