ABSTRACT:
When a decoding unit 6 fails in reading bar code information, a control unit 5 writes a corresponding error code into a ring table in the storage unit 4. In an error analyzing mode, the control unit 5 causes a measurement to automatically end when the decoding unit fails to read bar code information after the same bar code information is read a preset number of times or more, when the same bar code as that previously read is read and then bar code information different from that read by the preceding reading operation is read, or when a specific read error occurs. The indicator unit 7 indicates a number of the operations of reading bar code information and a read rate by changes of light colors emitted from light emission diodes of two colors, in a second normal measuring mode, and first and second test modes.
