    摘要: A laser radar including laser beam generating means, photo detecting means, a mirror, light deflecting means, and rotation driving means. The laser beam generating means emits a laser beam having an axis thereof. The photo detecting means detects a reflected laser beam that is reflected back by an object. The mirror includes a through-hole that passes the laser beam and a reflecting surface that reflects a reflected laser beam reflected back by the object toward the photo detecting means. The light deflecting means deflects the laser beam toward a measuring region and reflects the reflected laser beam from the object toward the mirror. The rotation driving means rotates the light deflecting means so as to direct the laser beam toward the measuring region.

    摘要: A portable radio station 1a transmits a communication-quality-confirmation pattern data "f" to a stationary radio station 2a, wherein a first communication quality information "1" is produced by measuring erroneous bits of the received signal. The first communication quality information "1" is transmitted from the stationary radio station 2a to the portable radio station 1a, together with a communication-quality confirmation pattern data "n". The portable radio station 1a receives both the first communication quality information "1" and the communication-quality confirmation pattern data "n", and produces a second communication quality information by measuring erroneous bits of the received signal. Then, the first and second communication quality information are independently displayed on a display section 18 of the portable radio station 1a.

    摘要: A 2-dimensional code reader includes a camera for scanning a surface which carries a 2-dimensional code thereon, an amplifier for amplifying electric signals fed from the camera, a device for identifying a code-region out of the scanned surface and a device for detecting information contained in the 2-dimensional code. The amplifying rate or gain is controlled according to a signal level representing a brightness of the identified code-region, not depending on a brightness of a whole scanned surface. The amplifier may includes an automatic gain controller which controls the amplifying rate according to the brightness of the whole scanned surface. In this case, the amplifying rate is adjusted based on an areal ratio of the code-region to the whole scanned surface area to obtain a clear image of the code, irrespective of the brightness of the scanned surface. Some symbol marks may be included in the 2-dimensional code in order to effectively identify the code-region on the scanned surface.

    摘要: An optical information reader which can promptly eliminate mirror reflection regions with high accuracy without the need for a plurality of expensive CCDS. When it is discriminated that mirror reflection regions exist in an image of a two-dimensional code obtained by a CCD under illumination condition 1, the condition is changed to illumination condition 2 and an image is obtained. If there is a mirror reflection region also in the new image, the previously obtained image and the new image are synthesized by calculating the OR. When no mirror reflection regions exist in the synthesized image, a decoding is executed. Since it is sufficient to use only one CCD in the optical information reader, system cost is minimized. As images are obtained by the same CCD, even if images are synthesized, a positional deviation does not occur, the mirror reflection regions can be promptly eliminated with high accuracy, and an obtained image is accordingly very accurate.

    摘要: To accurately read optical information more than an opening diameter of a read opening without the read opening contacted with a reading object, in a reader for reading a bar code by irradiating light from a light source to a bar-code label, converging the reflected light through a mirror and a stop by a lens and focusing the converged light on a line image sensor with a shutter, a wavelength detector for detecting a wavelength of the reflected light and a light guide for irradiating light spots indicative of a readable range to the label are provided. Whether a reading state is in a contact reading state in which a read opening contacts the label or in a noncontact reading state in which the read opening separates from the label is determined based on a wavelength of the reflected light detected by the wavelength detector. A light emission quantity and a shutter speed are controlled so as to keep an incident light quantity to the image sensor at an optimum value on a basis of the decided result and reflected light intensity obtained by integrating a line sensor output.

    摘要: A power supply apparatus suitable for a hand-held terminal or the like. In response to a power supply switch turning on, a voltage of a battery is supplied to a boosting voltage circuit and maintained through a diode at a charge capacitor and then applied to a memory, thereby allowing the hand-held terminal to operate normally. While the power supply switch is turned off, the supply voltage stored in the capacitor and applied to the memory is compared with a reference voltage in a comparator. When the supply voltage is lower than the reference voltage, the comparator outputs a signal to a control circuit couple the battery to the boosting circuit for a predetermined time so as to re-charge the capacitor and therefore guarantee back-up of the memory. This arrangement allows the use of the hand-held terminal for a longer time than is normally achieved concurrently with a normal operation of the hand-held device.

    摘要: A great number of bar codes are recorded in dual directions on a bar code information card. Each bar code is comprised of a plurality of bar symbols juxtaposed in parallel to each other. A plurality of bar codes, constituting one group bar code, are arranged in one direction which is orthogonal to the bar symbol and a plurality of group bar codes are arranged in the other direction in which the bar symbol extends. A great deal of bar-coded information is recognized by transferring the bar code information card in the longitudinal direction of the bar symbol and scanning the bar code orthogonally thereto.
