    摘要: The optical path of the light having spread at each point of an object to be shot is limited by an iris unit of a density filter. Since the density filter unit has a desired transmittance characteristic, the amount of the light passing through the density filter unit continuously changes from the center of the luminous flux toward the periphery. After the luminous flux forms an image on the image forming surface, it spreads toward the light-receptive surface of an image sensor, and becomes an image spreading on the light-receptive surface in a predetermined range.

    摘要: An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. On a circuit substrate mounted an image sensor, a plurality of light-emitting devices are mounted in the peripheral positions of the image sensor. By means of a ring-shaped light guide member, the light from the plurality of light-emitting devices is guided to an image capturing range, so as to illuminate the object. With this, by mounting a light receiving system and a light emitting system on an identical substrate, miniaturization can be achieved, and the image capturing range can be illuminated by substantially uniform light. Also, using the ring-shaped light guide member, an optical unit is housed inside the ring, thus enabling further miniaturization.

    摘要: In a bar-code reader, a reading unit reads characters from a bar code, based on parameters. A storing unit stores a plurality of signal-waveform information corresponding to a plurality of character patterns. A selecting unit makes an operator select a correct-reading character from among a plurality of the characters, if there is an occurrence of a wrong reading. A comparing unit compares a pattern corresponding to the correct-reading character selected and a pattern acquired from a plurality of signal-waveform information while changing the parameters one by one. Based on a comparison result, a parameter-setting unit sets in the reading unit, the parameters for which the occurrence of the wrong reading is least.

    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.
