構。[Claims for Utility Model Registration] In a magnetic tape recording device having a rotation mechanism in which a supply reel stand and a take-up reel stand rotate in accordance with the rotational direction of a drive means via a transmission means, a drive gear which is attached to the shaft and has a large diameter tooth portion and a small diameter tooth portion and rotates when the rotational driving force of the drive means is transmitted thereto; An intermediate gear having a gear and a second intermediate gear coaxially having a large-diameter tooth portion press-fitted into a cylindrical portion of the first intermediate gear, to which the rotational driving force of the drive gear is transmitted, and a second intermediate gear having a large-diameter tooth portion. The rotational driving force of the first intermediate gear is transmitted to the idler gear, which engages with the reel base teeth of either the supply reel base or the take-up reel base when it moves, and the idler gear, which is rotatable around the rotation axis of the drive gear. A rotary lever is fitted to the shaft and the rotating shaft of the intermediate gear and idler gear is attached to it, and the rotary lever is located at the lower end of the cylinder of the intermediate gear and has an inclined surface at the end so that it can slide. The intermediate gear is moved up and down along the axis, and the large-diameter teeth of the drive gear, the small-diameter teeth of the intermediate gear, and the large-diameter teeth of the idler gear engage, and the small-diameter teeth of the drive gear and the large-diameter teeth of the intermediate gear engage with each other. It consists of a gear and a switching lever that selects either engagement between the small-diameter teeth of the intermediate gear and the idler gear, and when the drive means rotates, the idler gear moves between the supply reel stand and the take-up depending on the direction of rotation. Rotation of a magnetic tape recording device characterized in that the reel base is selectively engaged with any one of the reel base teeth of the reel base, and the selected reel base is rotated at low speed and high speed by operating a switching lever. mechanism. A switching lever has an inclined surface at its end and raises or lowers the intermediate gear by sliding the switching lever;
It is composed of an idler gear that engages with the intermediate gear and engages with the teeth of either the supply reel stand or the take-up reel stand.If the switching lever does not slide and the intermediate gear does not rise, The rotational driving force of the driving means is transmitted to the small-diameter teeth of the driving gear, the teeth of the second intermediate gear, the teeth of the first intermediate gear, and the teeth of the idler gear, and the idler gear is connected to the supply reel by the rotational direction of the driving means. The magnetic tape is moved in one direction between the stand and the take-up reel stand and engages with the teeth of either the supply reel stand or the take-up reel stand to perform low-speed playback of the magnetic tape on the forward or return path; When the switching lever slides and the intermediate gear rises, the rotational driving force of the driving means is transmitted to the large-diameter teeth of the driving gear, the teeth of the first intermediate gear, and the teeth of the idler gear, and the rotational driving force is transmitted to the large-diameter teeth of the driving gear, the teeth of the first intermediate gear, and the teeth of the idler gear.
