きるため、走行開始直後においても走行が安定する。As mentioned above, it is possible to set the height of the magnetic tape 2 only by adjusting the inclination angle of the inclined guide 10, but it is possible to set the height of the magnetic tape 2 by simply adjusting the inclination angle of the inclined guide 10. By lightly abutting the end of the magnetic tape, more stable tape running can be obtained. In addition, in the case of only the inclined guide 10, when the magnetic tape 2 is in a stopped state (stop), the magnetic tape 2 will fall down due to its own weight, and if it starts running in this state, the running of the magnetic tape 2 immediately after starting running will be interrupted. It becomes stable. For this reason, a guide 9 with a flange is provided, and this lower flange 9b
By lightly contacting the lower edge of the magnetic tape 2, the magnetic tape 2 can be set at a predetermined height even when it is stopped, so that running is stable even immediately after starting running.
