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： 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 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.

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 light source and a light responsive sensor are optically coupled to recognize information such as bar codes recorded on an object. The light source projects illumination light onto the object and the sensor receives the reflected light the density of which represents the recorded information. The sensor is swept to convert the light density into an image signal which is then passed through a filter. An image signal, the low frequency noise signal component resulting from the fluctuation of the illumination light being excluded therefrom by the filter, is available for recognizing the recorded information precisely.
