Claims

[Scope of Claim for Utility Model Registration] ■ Each shaft 31 of two idlers 3°4: tooth surface idler 3 for play rotation and friction idler 4 for fast forward/rewind rotation.
41 is engaged with a cam hole 6 formed in the cam plate 5, and both idlers are held in a neutral position by displacement of the cam plate 5 driven by the mode switching device 1, or one of the idlers is held in a take-up reel. In the reel stand drive device that engages with the stand 11 or the supply reel stand 12, the drive shaft 17 is provided with a gear 2 and a cylindrical portion 21 on the same axis, and the toothed idler 3 is connected to the drive cape 7. The arm 2 is supported by the drive shaft 17 so as to be freely rotatable relative to the arm 2.
2 and meshes with the gear 2 on the drive shaft 17;
The friction idler 4 is supported by a support plate 7 that is slidably disposed in a plane orthogonal to the drive shaft 17, and is disposed opposite to the cylindrical portion 21 on the drive shaft 17 so as to be able to approach and separate from it. A magnetic tape reel stand driving device in which the support plate 7 is urged toward the cylindrical portion 21 by a spring 70 with one end fixed, and the support plate 7 is linked to the cam plate 5 to follow the movement of the cam plate 5. ■ The mode switching device 9 has a roller 9 at one end with respect to a cam formed on the outer periphery of the loading disk 93 of the VTR.
2. The magnetic tape reel stand driving device according to claim 1, which is a registered utility model.
