Abstract

PURPOSE: To realize an early detection for the faulty state of the tape travelling, by providing an optical detection means.
CONSTITUTION: The endless tape 11 coiled around the outer circumference surface of cylindrical ring-shaped fixed reel jumps over the fixed reel from the innermost circumference of the tape coil part to be coiled around the outermost circumference of a tape through the tape lead-out hole 21 formed to the fixed reel and via the head 23, capstan 24, pinch roller 25 plus the guides 26a and 26b. The tape state detecting means consists of the light source 41 and the optical detector 42 and is located so as to receive the reflection of the capstan 24. Accordingly, the optical path 43 is cut off to detect the faulty state in case the tape is wound round the capstan 24 or the tape is detached from the guide 26a to have a sag.
