Abstract

PURPOSE:To measure stably a size change and a meandering state of tape width, by imaging through an optical system on a CCD image sensor images of both edges of a tape that travels on a tape guide not restricted in the width direction. CONSTITUTION:Images of both edges of a tape on a tape guide are imaged through an optical system on a CCD image sensor, and an absolute value of size of tape width and a variation of the width are measured from said images. For example, tape to be inspected 5 is passed through the upper part of the tape guide 12 incorporating an illuminating lamp 12a in built-in manner and restricted in the width direction, and images of both edges of the tape are imaged, using an optical system comprising a movagle mirrow cylinder 13, a fixed mirrow cylinder 14 and others, on a CCD image sensor part 15a of a camera part 15, and are subjected to a signal processing by a printed board 15b and an attached electronic circuit 15c. Thereby an absolute value, a variation and a meandering state of the tape width can be measured continuously, simply, stably and accurately.
