摘要:
A bar code reader includes a line sensor having a scanning range large enough to scan two or more bar codes. A portion of the scanning range having a size corresponding to a single bar code is determined as a reading range. A reading range comparator 35 determines when a bar code is positioned within the reading range, so that no other bar code within the scanning range will be read. The reader also has error detection to determine whether counted numbers of bars fall within a permissible range for a given bar code symbology.

A bar-code remote-control device includes a first key for inputting a detection instructing signal and a second key for inputting a transmission instructing signal. The device also includes a gate circuit which is opened after completion of a processing in a remote-control data transmission processing section to permit entrance of the detection instructing signal in a bar-code detection processing section and is closed upon completion of bar code detection processing in the bar-code detection processing section to prohibit entrance of the detection instructing signal in the detection processing section, so that no error occurs upon simultaneous operations against the first and second keys.

A tire pressure measuring system (TPMS) for transmitting pressure information from a tire to a vehicle body has a complicated structure when a plurality kinds of transmission data exist. A sensor unit receives a transmission electromagnetic field from a sensor control unit, and rectify-detects the received field. The counter of the sensor unit determines a rotation cycle of a tire, based on the signal obtained by the rectification detection, then switches the switch in conjunction with the rotation cycle, and sequentially sends the plurality of transmission data items for every tire rotation.
