摘要： A demodulated data storage buffer is stored with bar width data sets obtained by scanning a coupon code with a scan optical system. A CPU first executes a demodulating process on these bar width data sets in accordance with a demodulation algorithm in a WPC code system. If an end guard bar (RGB) of the WPC code is contained in the demodulated data by the demodulating process, the demodulating process is executed on the same bar width data sets in accordance with a demodulation algorithm in a CODE 128 code system.

摘要： A proximity sensor receives light beams reflected from a goods. A proximity sensor control unit determines that the goods exists when a light quantity of the reflected light received by the proximity sensor exceeds a determination threshold value. The determination threshold value increases as elapsed time since the bar code was read last time becomes longer, and, as a result, a detection sensitivity decreases. A CPU restores a duty of irradiation of the laser beam back to 100% and resumes rotations of a motor for driving an operation optical system when the proximity sensor control unit determines that the goods exists.

摘要： A bar code recognizing/demodulating circuit compares with each other a demodulated data string including a start bar but excluding an end bar and a demodulated data string including the end bar but excluding the start bar among a variety of demodulated data strings obtained by a scan/convergence optical system scanning a bar code. A total sum of the numbers of digits of the two demodulated data strings is detected, and whether the total sum is larger than the number of digits of the bar code to be read is checked. If larger than the number of digits of the bar code, whether data of overlapped portions of the two demodulated data strings coincide with each other is checked. If coincident, demodulated data corresponding to the whole bar code are synthesized based on the two demodulated data strings.

摘要： An image capturing apparatus illuminate and captures an image of an object using reflected light from the object. In the apparatus, a plurality of light-emitting devices are mounted in the periphery of an image sensor, and the light of the plurality of light-emitting devices is guided to an image capturing region by a light guide member for illumination. On the image capturing apparatus having the image capturing system disposed close to the illumination system, a hood is provided for optically intercepting the image capturing system from the illumination system, with a flange disposed thereon. The light reflected on the upper face of a filter can be intercepted from being incident on an image capturing system unit. Accordingly, output light not irradiating the object and causing an image capturing noise can be intercepted, which is effective for a clear photographed image.
