    摘要: An optical scanner suitable for use with a bar code reader includes a light source for generating a laser beam, a laser beam scanning device, a scanning pattern generating optical system, and a signal light condensing optical system for deflecting scattered signal light scattered by an object to be read to introduce the light to a photo-detector. The scanning pattern generating optical system or signal light condensing optical system includes two reflective holograms disposed substantially in parallel with each other to produce a reflection beam having an angle of reflection which is different from an angle of incidence of the laser beam thereon. The scanner is a miniaturized apparatus as a result of the reflection holograms.

    摘要: A laser beam scanning system includes a laser for emitting a laser beam modulated with image information to be recorded and a deflecting device, such as polygon mirror, for deflecting the laser beam over a predetermined angle repetitively, so that the laser beam is scanned on a scanning surface, thereby an image is formed on the scanning surface. When a plurality of laser beams are used at the same time, the plurality of laser beams are arranged in an array inclined with respect to the scanning direction. In this case, a sync sensor generates a sync signal in response to a laser beam received in the first place. When a polygon mirror is so structured to have a reflecting surface which is defined by a curved surface having a predetermined radius of curvature, a f.theta. lens may be discarded. In this case, when a transparent layer is formed on this curved reflecting surface, no distortion in scanning speed is produced even without using any electrical correction. Besides, it is also preferable to control the intensity of laser beam so as to maintain the image density of a resultant image at constant.

    摘要: A moving device assembly includes a moving device and a shield. The moving device is movable between a first position and a second position, to move a detector including a detection surface relative to an opposing member disposed opposite the detector. The shield shields the detection surface of the detector. As the moving device is at the first position, the detector is at a proximal position at which the detector is near the opposing member, and as the moving device is at the second position, the detector is at a shield position at which the detector is separated from the opposing member and the detection surface of the detector is shielded by the shield.

    摘要: A position Z of an image sensor is moved to an initial position A (image forming position) in a Z axis direction. An exposing operation is performed at a position A, and it is determined whether or not an exposing time counted by a timer has reached ta. If the exposing time has reached ta, an image sensor 27 is moved to a position B. The exposing operation is performed at the position, and it is determined whether or not a total exposing time has reached ta+tb. If the total exposing time t has reached ta+tb, the image sensor is moved to a position C, and the exposing operation is performed at the position. Thus, the output distribution of the image sensor can be assigned a desired low pass filter characteristic.

    摘要: Positioning displacement characteristics of each of scanning beams are obtained in advance. The positioning displacement characteristics is indicative of a relation between temperature and a displacement amount by which each of the scanning beams is displaced in a sub-scanning direction. A displacement control is performed based on the positioning displacement characteristics by shifting the positioning displacement characteristics in a direction opposite to that of a trend of the positioning displacement characteristics within a pixel pitch.
