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： 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.

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.
摘要翻译： 激光束扫描系统包括用于发射用待记录的图像信息调制的激光束的激光器和诸如多面镜的偏转装置，用于使激光束重复地偏转预定角度，使得激光束被扫描 扫描表面，从而在扫描表面上形成图像。 当同时使用多个激光束时，多个激光束被布置成相对于扫描方向倾斜的阵列。 在这种情况下，同步传感器响应于首先接收的激光束产生同步信号。 当多面镜被构造为具有由具有预定曲率半径的曲面限定的反射表面时，可以丢弃fθ透镜。 在这种情况下，当在该弯曲反射面上形成透明层时，即使不进行任何电校正，也不会产生扫描速度的变形。 此外，还优选控制激光束的强度，以便使得到的图像的图像浓度保持恒定。
