<p>PURPOSE:To stably travel a tape by winding up a cassette side tape and a shifter side tape from a tension arm respectively around prescribed collared oscillation type and uncollared drum type guide rollers at the time of loading the tape. CONSTITUTION:When a cassette is loaded to the magnetic recording/reproducing device and a tape starts to be loaded, the cassette side tape part of the tape is wound around the 1st guide roller 110 of the tape traveling guiding mechanism from the tension arm 96 by an oscillation roller having collars on both the ends of a cylindrical roller and supporting the intermediate part of the roller by a bearing. On the other hand, the tape shifter (43) side tape is wound around the 2nd guide roller 119 constituted of supporting a cylindrical roller having collars on both the ends by two upper and lower bearings from the tension arm 96. In the constitution, the guide rollers 110, 111 almost surely absorb and adjust a height direction size difference between the magnetic tape stored in the cassette and the centers of the magnetic heads 14, 15 by rational co-operation work, and at the time of arrival of the tape at a position between a capstan 17 and the magnetic head 15, the tape is carried to a regular position.</p> |
