<p>PURPOSE:To suppress the slackness of a tape, and to realize stable tape travel by providing a contact prevention guide for preventing the contact of the tape occurring between respective guides at the incoming side and the vicinity of the outgoing side of a cylinder. CONSTITUTION:The tape 1 in a cassette 2 is drawn out along a loading route A, and is wound around the cylinder 3 extending over a wide angle a little less than 360 deg.. Then, in a loading finished state, the parts of the tape 1 positioned at tape paths 1a, 1b are in contact with the tape contact prevention guide 4 installed at a guide plate 15 respectively from both sides, and wound themselves around it by the prescribed angle. The tape 1 held in such a manner absorbs the slackness of the tape occurring on the tape paths 1a, 1b in a tension released state at the time of a stop mode at the finish of tape loading or the slackness of the tape occurring by the travel regulation of the tape during the tape travel and so on, and prevents the contact of the tape to the tape on the tape paths 1a, 1b. Thus, the slackness of the tape 1 is suppressed, and the stable tape travel is secured.</p> |
