Claims

[Scope of utility model registration request]

During tape loading, the loading mechanism moves the guide rollers and slant poles on the supply side and the slant poles, guide rollers, and pinch rollers on the take-up side from the cassette half side to the rotating drum head side, and magnetically transfers the tape from the supply side reel inside the cassette half. The tape is pulled out, the magnetic tape is wound around the rotary head drum through the guide roller and slant pole on the supply side, and then the magnetic tape is wound around the pinch roller through the slant pole and guide roller on the take-up side. In the tape running device that runs the magnetic tape along a route that passes between the capstan that presses the magnetic tape and reaches the take-up reel in the cassette half, the guide roller on the take-up side is removed, and the capstan and the pinch roller are also removed. A guide roller made of a soft elastic material that also functions as a pinch roller is provided at the position of the guide roller on the winding side when the tape runs at a constant speed, and a capstan is provided at a position corresponding to the guide roller,
When the tape is running at a constant speed, one of the guide rollers or the capstan is moved so that the magnetic tape is pressed against the magnetic tape, and when the tape is stopped or the tape is running at high speed, one of the guide rollers or the capstan is moved so that the magnetic tape is pressed against the magnetic tape. A tape running device characterized in that it is configured to include a moving mechanism that moves the tape so that it is released.
