Description

[Brief explanation of the drawing]

Fig. 1 is a sectional view of an embodiment of the present invention, Fig. 2 is a diagram for explaining the balance of the moment of inertia, Fig. 3 is a sectional view of a conventional normal pinch roller device, and Fig. 4 is a capstan view. FIG. 5 is a cross-sectional view of a conventional thin pinch roller device with a shortened axis and a shortened pinch roller for thinness. FIG. 5 is a diagram for explaining the balance of the moment of inertia of the conventional example shown in FIG. 1...capstan shaft, 2...pinch roller,
3...Pinch roller shaft, 4...Pinch roller bearing, 5...Magnetic tape. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] In a magnetic tape drive device configured to run a magnetic tape while sandwiching it between a capstan shaft and a pinch roller and at a position near the open end of the capstan shaft, a single bearing supporting the pinch roller is provided. Displace the pinch roller from the center line of the magnetic tape in the direction of the widthwise center of the pinch roller,
A magnetic tape drive device characterized in that the pinch roller is disposed at a position where the magnitude of the moment of inertia generated on both sides of the bearing is balanced when the pinch roller is pressed against the capstan shaft.
