A transmission shaft 11 is installed at a position deviated from the center of the shaft 10.
Then, a rotational force is transmitted to the transmission shaft 11 by a timing belt 12 mounted between the drive disk 9 and a pulley provided coaxially. Further, the transmission shaft 11 projects from the driven disk 10, and this projecting portion is formed on the capstan input shaft 13.

In FIGS. 1 and 2, the capstan 7 is rotatably installed inside a driven disk 10, and a capstan drive shaft 14 of the capstan 7 is projected to the outside of the driven disk 10. ing. The capstan input shaft 13 and the capstan drive shaft 14 are both spline shafts.

A speed change pulley unit 15 is detachably provided on a capstan input shaft 13 and a capstan drive shaft 14 which are projected from the driven disk 10. The speed change pulley unit 15 has two pulleys 17 and 18 rotatably provided on a unit substrate 16 at the same distance as the distance between the capstan input shaft 13 and the capstan drive shaft 14 and different in outer diameter. 1
Timing belt 19 is attached to 7,18. Further, the shaft holes at the central portions of the pulleys 17 and 18 are structured so that they can be detachably fitted to the splines of the capstan input shaft 13 and the capstan drive shaft 14.

Reference numeral 20 denotes a stopper pin for fixing the unit substrate 16 to the driven disk 10, which is provided on the driven disk 10 so as to be slidable in the axial direction, and the base end portion 21 facing the driven disk 10 has the pin as a driven disk. A spring 22 for urging the inside of 10 is attached, and a front rectangular stopper piece 23 is provided at the tip. Furthermore, a through hole 24 having a shape through which the stopper piece 23 can pass is formed in the central portion of the unit substrate 16.

The speed change pulley unit 15 can obtain a capstan of a desired rotation speed by preparing a plurality of combinations in which the outer diameters of the pulleys 17 and 18 are different.

Reference numeral 25 denotes a sprocket provided on the capstan 7 for interlocking with the other capstan 7a (see FIG. 4) by a chain 26.

The embodiment is configured as described above, and the capstan input shaft 13 of the transmission shaft 11 protruding from the driven disk 10 on the take-up side and the capstan drive shaft 14 of the capstan 7 are provided with a unit substrate.
The shaft holes of 16 pulleys 17 and 18 are fitted to connect the transmission shaft 11 and the capstan 7, and the stopper pin 20 is inserted into the through hole 24.
