Abstract

PURPOSE:To reduce the size of constitution and to utilize space effectively, by tensing a torsion coil spring nearly at right angles to a line running through both centers of rotation of a capstan and a pinch roller with a lever, and bringing the pinch roller into press contact with the capstan. CONSTITUTION:When a tension lever 33 is drawn as shwon by an arrow D, a pin base 29 rotates around a shaft 23 as a fulcrum as shown by an arrow E through the torsion coil spring 32 and a rotary lever 27 has the other end side pressed by a pin 30 to rotate around a shaft 26 as a fulcrum as shown by an arrow F. Consequently, a pinch lever 23 is pressed by one end of the rotary lever 27 to rotate against a spring 25 as shown by an arrow A, bringing the pinch roller 22 into press contact with the capstan 21. When the tension lever 33 is further drawn successively as shown by the arrow, the pin 31 leaves the end part of the long-sized hole 34 of the tension lever 33. In this state, when the tension lever 33 is stopped, the pinch roller 22 comes into press contact with the capstan 21 with specific pressure based upon the recoiling force of the torsion coil spring 32. Thus, the press contact of the pinch roller 22 with the capstan 21 is controlled.

As a device for controlling the pinch roller 1llJ for bringing the pinch ruler into pressure contact with the capstanshin through the magnetic tube 1 only during recording and reproduction, a device made by Kirinari shown in FIG. 1 has conventionally been used. That is, 1 is the capstan,
1 is a pinch roller, and J is a pinch lever that supports the pinch roller 2 and the capstan 1 in a **i possible manner. The pinch lever 3 is rotatably provided with a shaft 41 as a fulcrum, and is given a rotational force by a spring 5 in the direction of the arrow A to move the pinch roller 2 away from the steering wheel 1.

An intermediate portion 7a of a rotating lever 7 whose one end is pivotally supported by a shaft 6 is in contact with the pinch lever 3. A pin 8 is attached to the other end of this rotating lever 7, and a pin 8 is attached to the other end of the rotating lever 7.
',' The elongated hole 10 formed at one end of the L-bar 9 is connected to the tension lever 1, and the coil spring 12 is stretched between the pin 8 and the pin 11 provided on the tension lever 9. has been done.

When the rotating lever 1 is rotated in the direction of the arrow C, the pinch lever 3 is rotated in the opposite direction to the arrow C against the force of the spring, and the pinch roller 2 is rotated in the direction of the magnetic peak f. Press it against Stan 1. In this state, as shown in FIG. 1(b), the distance between pin 8 and pin 11 is equal to
The pinch roller 2 expands slightly against the capstan 1, and the pressing force of the pinch roller 2 against the capstan 1 is given by the restoring force of the coil spring 1, which is in an expanded state from when it is stretched.

By the way, in the state shown in FIG. 1(b), the tension lever 9 is stopped after moving a predetermined distance in the direction of arrow B, but the stopping position varies by one movement depending on the dimensional tolerance. Even if the distance between the pin 8 and the bottle 1 changes somewhat due to this fluctuation, it is important to prevent the pressure force of the pinch roller 1 against the capstan 1 from changing greatly in order to obtain stable tape running 1. For this purpose, it is necessary to reduce the spring constant of the coil spring 12 by 1. However, if the spring constant of the coil spring 11 is reduced by /J-, its outer diameter becomes large, which becomes a factor leading to an increase in the size of the device.

In addition, in the structure shown in FIG. 1, the tension lever 9 is pulled in the direction in which the pinch row 22 is pressed against the capstan 1, that is, in the direction parallel to the koji passing through the inner rotation center t of the capstan 1 and the pinch row 22, which makes space effective. It was also disadvantageous in terms of usage.

\Even if you use 1 small item, its external dimensions will not increase that much. In addition, in the conventional r & position, the coil spring 12 is in an expanded state compared to when it is in the vertical position, so its shape becomes large, but in this invention, the torsion coil spring JJ is twisted even when the pinch roller 22 is pressed. There is only a slight change in the corners and no increase in external dimensions; therefore,
