Abstract

PURPOSE: To prevent the operator and so on from intercepting the light path of the sensor unconsciously to prevent read impossibility, by providing a preventing means to prevent the light path of the sensor from being intercepted at the bar-code read start time and the read end time.
CONSTITUTION: A fixed scanner is incorporated in bar-code reader 1, and the bar- code on articles is read by bar-code read window 2. This read is started at the detection timing of read start sensor 3 and is terminated at the detection timing of read end sensor 4. This reader 1 is provided with light path guides 21aW21d, and further, read start auxiliary sensors 41aW41b and read end auxiliary sensors 41cW 41d are arranged on the read light path. The time from read start dependent upon sensor 3 is counted by timer 51a, and alarm is issued from alarm equipment 51b if the signal of sensor 4 is not obtained after a specified time, thus obtaining the preventing means to prevent the light path from being intercepted, read impossiblity is prevented by this preventing means.
