A bar code reader has an arrangement to communicate with a host apparatus. The bar code reader includes a read unit that reads a bar code attached to an article, and outputs bar code information corresponding to the read bar code; a term information acquisition unit that acquires term information included in the bar code information; and a term expiration check unit that checks whether the term of the article has expired based on the term information. A notification unit notifies that the term of the article has expired upon determination by the term expiration check unit that the term of the article has expired.

In a bar-code generally number of modules corresponding to each character is seven. However, if the number of modules judged from the data obtained by reading a bar code is, for example, six, the character is demodulated using a demodulation-pattern table corresponding to six modules.

Cavitation is reduced in a rotary pump while the pump performance is maintained by utilizing a low-temperature fluid source already present in the pump system. The fluid from the low-temperature fluid source receives heat from the fluid flowing to the pump, thereby lowering its temperature and the saturated vapor pressure, which increases the allowable margin for a decrease in fluid pressure and reduces the occurrence of cavitation. The pump system may be used for a liquid rocket engine. The fluid velocity of the fluid directed to the pump is low before releasing heat, so there is only a slight pressure loss at the pump. Accordingly, the temperature is lowered and the occurrence of cavitation is reduced within the pump.

A commodity information management system including a deactivator for deactivating a security tag activated and attached to a commodity after a barcode is read by a reader, a magnetic detector for detecting magnetism of the security tag having been deactivated by the deactivator, and a control section for sending the result of detection by the magnetic detector to an operator with an LED and a speaker. The operator recognizes whether the security of the security tag is released or not according to the light through the LED and sound by the speaker.

Bar with count values indicating widths of white and black bars, which are reciprocally obtained, are input to buffers connected in series at 16 stages. The bar width count values written to those buffers are sequentially shifted each time a new bar width count value is input. A comparing circuit compares the widths of the adjacent bars in the same color with each other and checks whether or not a ratio therebetween falls within a range of 0.2-5.0 times as large as each other. Results of the comparisons by this comparing circuit are written to result registers connected in series at 13 stages. The check-results written to those result registers are sequentially shifted each time a new bar width count value is input. Accordingly, if all the check results written to all the result registers indicate an "in-range" state, it follows that the fifteen or more bars consecutively meet a bar code condition. Hence, the counter lets an AND gate open. If even one of the check results written to the result registers indicates an "out-of-range" state, the counter starts counting. Then, when a count result reaches 17, the counter lets the AND gate close. Therefore, just when one of the check results written to the result registers is in the "out-of-range" state, the bar width count value written to each buffer is output. The bar width count values input thereafter are disposed of.

This invention is intended to contribute to improvements of the reading accuracy of a bar code reader and performance of a POS system or the like. To attain this object, according to the invention, when one of the data blocks constituting a bar code cannot be detected, addresses of the non-detected data block are determined based on a width of the detected data block and addresses of the center bar. The invention is constituted such that data of the previously non-detected data block is detected based on its addresses.
摘要:
An apparatus for demodulating bar codes is disclosed. In this apparatus of this invention, a distortion quantity calculation unit for calculates a distortion quantity of a bar width of a character to be demodulated by use of bar code data generated by reading the bar codes in which characters are expressed by bar widths. A distortion quantity determining unit determines whether or not a bar width distortion quantity calculated by the distortion quantity calculation unit falls within a range of predetermined values. A first demodulation unit, when determining that the distortion quantity of the bar width falls within the range of the predetermined values, demodulates the character from the bar code data by effecting a first correcting process on the bar width distortion quantity. A second demodulation unit, when determining that the distortion quantity of the bar width does not fall within the range of the predetermined values, demodulates the character from the bar code data by effecting a second correcting process on the distortion quantity of the bar width.
