易にできない等々がある。As described in the prior art, in the method of measuring the tape by winding the roller on the tape, the data of the true tape tension amount cannot be obtained, and the magnetic surface of the magnetic tape is not measured. Not only does the quality of the product deteriorate due to scratches, dirt, etc., but the tape during running is stopped at the time of measurement, and it not only takes time to pull the tape on the roller, but also the vibration of the roller bearing is strain gauge. There is a problem that the noise of the roller bearing vibrates the environment while the tape is running, and that the adhesive tape-coated gum tape, cellophane tape, and double-sided tape cannot be easily measured.

The compressed air set by the device (9) is supplied to the solenoid valve (11) through the blower pipe (10), and the solenoid valve (11) is opened by the solenoid valve control pulse (26) of FIG. By supplying air to the compressed air blower (13) through the blower pipe (12) and blowing a vertically long compressed air blowout pattern (14) in the width direction of the tape surface (4) onto the tape surface (4), As in 2, the tape surface (4) bends The reflected light of the infrared light spot on the tape surface (4) is reflected by the light receiving surface of the distance detecting element (6) through the aspherical light receiving lens (5), and the distance of the infrared light path length becomes the tape tension amount.

果を奏する。In the conventional measuring means, a strain gauge is attached to a leaf spring, a roller is attached to the tip of the leaf spring, and the tape surface is entangled with the roller for measurement. Therefore, noise due to vibration of the bearing in the roller is measured. It is effective to measure the tape tension amount in a non-contact manner because it mixes with the measured tension value and cannot measure accurately, and the roller noise causes the environment to be obstructed by running the tape. .
