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 extractor extracts a part that is apparently a bar-code signal from a signal that is subjected to opto-electric conversion. A narrow-band differential processor forms a waveform of an edge by differentiating by using a module frequency. The module point extractor extracts the module point from the waveform. The maximum likelihood judgment processor 5f performs ternarizing based on a maximum likelihood method by using broader information.

摘要： A still image of a moving object is restored from portions including the object in an image by using a movement distance of the object during an exposure time and the difference value between output values of adjacent pixels, the movement distance being calculated as a number of pixels. Therefore, especially in cases where a moving bar code is imaged, even if the image of the bar code is blurred as a result of the movement of the bar code during imaging, a still image of the bar code in which the outlines of the black portions and white portions of the bar code are clear can be obtained. Accordingly, bar code information can be read out from the imaged bar code.

摘要： A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector. The light-receiving surface of another detector is faced downward to receive the beam reflected by the bar code through Fresnel lens and mirror, thereby to decrease the depth of the bar code reader. Furthermore, the beam passage from the reflection mirror goes through the lower surface of the polygon mirror intersecting the axis of rotation of the polygon mirror.
