Abstract

PURPOSE: To detect a label securely by a method wherein a photodetector and a signal-converting detector are provided on the carrying path of a carried body through which a releasing mount and a label pass.
CONSTITUTION: Light emitting diodes LED1, LED2 as light sources which are arranged through a carrying body 1 and two phototransistors PH1, PH2 as light detectors are equipped in a device. The 1st phototransistor PH1 is arranged on the carrying path 15 of the carried body through which the releasing mount 2 and the label 3 pass so that transmitting light can be given from the light emitting diode LED1 and the 2nd phototransistor PH2 is arranged on the carrying path 16 through which the releasing mount 2 only passes so that transmitting light can be given from the light emitting diode LED2. Thus, since the change of quality of the releasing mount is compensated and adjusted by the 2nd phototransistor PH2, the label can be detected reliably.
