Abstract

PURPOSE: To simplify the unit, by providing the contrast sensor consisting of other projector and photodetector in addition to the inking line detection sensor, avoiding the misdetection due to the differene of reflection factor on the surface of wooden material, and making unnecessary the set of slice level.
CONSTITUTION: The inking line reader is located with the projector 14 providing the light emitting diode 11, slit 12 and lens 13 and the photodetector 18 providing the lens 15, slit 16 and photodiode 17, the reflected light from the surface of the wooden material 30 is received with the photodetector 18 to discriminate the inking line on the wooden material 30. In addition to the inking line read-in sensor 10 of the reader, the contrast sensor 20 consisting of the projector 22 by the light emitting diode 21, and the photodetector 26 by the lens 23, slit 24, and photodiode 25 is located, both the output signals are compared at the comparator of electric circuit provided with the reader, to avoide the misdetection due to the difference between the reflection factor from the wooden material 30, the set circuit of slice level is made unnecessary, to simplify the reader.
