Abstract

PURPOSE: To make high-precision measurement possible without a bad influence of vibrations, etc., by fitting a slit hole plate between a measurement light source and sensor.
CONSTITUTION: Under slit hole plate 2 where slit holes 1 of the same rectangular opening part are arranged zigzaging at constant intervals, in two parallel lines and in the logish direction symmetrically at the both ends part of the long board, long light source 3 is provided in the roller-axial direction between carrier rollers 4. Right over the slit hole street between those carrier rollers 4, a couple of sensors 5 for plate-width measurement capable of moving in the roller-axial direction, and sensor driver 6 are fixed to stand 7, and signal processor 8 operating sensor driver 6 by the reception signal of sensor 5 and plate-width detection unit 9 are connected. Consequently, the measurement basing upon the fixed length of the slit hole can be attained, so that high-precision measurement can be realized with no bad influence of vibrations, etc.
