Abstract
PURPOSE: To identify the error signal, by performing several times of information read-in with the process of the rotary operation deflection after comparison.
CONSTITUTION: The bar code written on the tag card 2 is read in with the detector 1. Rotary deflection system is adopted for the detector 1. The read-in information detected is interpreted 3 and data output is picked up via the buffer memory 4. Simultaneously, the scanning direction is checked by utilizing the characteristics on the bar code constitutuion, that is, the symbol at the both ends, and the scanning direction is adjusted by preforming the rotary deflection of the detector 1. The read-in signal is outputted for several times every angle in the process of the rotary deflection, and a plurality of readings are made to the same bar code. Further, it is compared 5 with the preceding signal of the buffer memory 4 and error identification is made, and if it is in error, the data output is cancelled. With this method, read-in error can be reduced.
