摘要： A POS system comprises a host computer providing a centralized control over a plurality of scanners, and a printer for printing a batch setting bar code or the like. A CPU of the scanner reads the changes in the setting from its own memory when it receives a first transmission request command and then transmits the data to the host computer as a first batch setting data. From this first batch setting data, a first batch setting bar code is generated. When this first batch setting bar code is read using the reader of the scanner whose setting has not been changed, the setting in the memory of this scanner is changed to the setting represented by the first batch setting data. Thus, setting in a plurality of scanners can speedily and accurately be changed.

摘要： A differentiation signal DF differentiated by a differentiation unit is inputted to a slice level generation unit and to comparators. A first peak-hold circuit and a voltage division circuit generate a slice level having a slice ratio SLR that is constant to a peak value VDF of the differentiation signal DF. A second peak-hold circuit generates a slice level the slice ratio SLR of which changes in accordance with the peak value VDF. The slice level generation unit outputs their synthetic slice level SLL, which is compared by the comparators with the level of the differentiation signal DF, outputting thereby binarized signals W-GATE and B-GATE. When the level of the differentiation signal DF is high, the slice level SLL approaches the peak value VDF. Therefore, noise components contained in the differentiation signal DF cannot exceed the slice level SLL. When the level of the differentiation signal DF is low, the slice level SLL has a constant ratio to the peak value VDF. Consequently, the peak value of the amplitude of the differentiation signal DF can be detected reliably.

摘要： A bar code reading apparatus including a reader for reading a bar code expressing a plurality of characters, and a CPU for decoding the characters according to a result of reading by the reader. A ratio between a character length Cy of an already decoded character E2 and a length Cz of a character E7 to be decoded is calculated. When this ratio is greater than a threshold value, the black bar width B1 and black bar width B2 are corrected according to a reference black bar width X. The CPU decodes the character E7 to be decoded according to the corrected black bar width B1 and black bar width B3.

摘要： A double-reading preventive control processing unit, when demodulated data corresponding to a whole bar code is obtained in an M10-OK buffer, notifies a reading-OK processing unit of this demodulated data on condition that a double-reading preventive timer is not actuated, stores a single-reading multi-stage buffer with this demodulated data, and actuates the double-reading preventive timer. The single-reading multi-stage buffer is capable of storing plural demodulated data in sequence from the latest one, of which the reading-OK processing unit has been notified. When demodulated data is newly obtained before the double-reading preventive timer makes a time-up, the double-reading preventive control unit checks whether or not the new demodulated data is identical with the demodulated data stored in the single-reading multi-stage buffer. When identical, this new piece of demodulated data is discarded. Whereas when not identical, the reading-OK processing unit is notified of this new demodulated data, and the single-reading multi-stage buffer is stored with the same data. The double-reading preventive timer is then re-started.

摘要： Demodulated data B containing the whole of a right block and a part of a left block is obtained after demodulated data A containing a start guard bar and based on a division reading process has been at first obtained. When demodulated data C containing an end guard bar and numerical data of three characters is thereafter obtained, a CPU aligns the demodulated data C with modulus 10-OK data obtained by synthesizing the demodulated data A with the demodulated data B on the basis of the end guard bar, and compares tenth through twelfth characters (of the numerical data) of both of data with each other. As a result of this comparison, if the tenth through twelfth characters (of the numerical data) of both of data are coincident with each other, the CPU increments an identical character counter.
