る。In view of the above-mentioned problems, the present invention has been developed in the anti-gravity direction.
The present invention provides a magnetic recording/reproducing device which aims to reliably press the shear idler 3 onto the supply reel stand 1 by adding the following.Means for solving the problemIn order to solve the above problem. The magnetic recording and reproducing apparatus of the present invention is provided with two reel stands for winding and supplying the magnetic tape and one motor serving as a driving source at predetermined positions, and for transmitting the rotational force of the motor to the reel stand. In a magnetic recording and reproducing device, an idler is provided between the reel stands,
The magnetic recording/reproducing apparatus uses the idler by operating it in a vertical direction, and has a configuration in which a full-force member is provided and the idler is biased in a counter-gravity direction.
