25 is a solenoid, 26 is a solenoid shaft, 27
．． 28 is an arm, and 29 to 32 are shafts.

In the figure, a rotary head device t1 is provided on the chassis 2, and a loading ring 17 is provided so as to be rotatable with this by a coaxial button. Although not shown, the rotary head device 1 includes a rotary i/9 cylinder on which a magnetic head is mounted and a fixed cylinder, and these cylinders are arranged at a predetermined angle with respect to the shear 2. The loading ring 17 has
A guide pace 2° on which guides 11 to 13 are mounted is connected by means not shown. Next, a guide plate 1, which is provided with a rail-shaped or four-shaped guide surface 19 around half of the outer circumference of the rotary head device 1, is fixed to the chassis 2, and when the loading ring 17 rotates, this guide Pace 20 and move 6 to guide surface 19. A catcher 21 is provided at one end of the guide surface 19 in the vicinity of the turning head split R1. Tape out 11!
A capstan 7 is provided which is rotationally driven by a capstan motor (not shown), and a head cleaning device 22 is provided near the rotary head device 1.

The figure shows a state in which the magnetic recording/reproducing device has completed loading, and the loading ring 17 has stopped at the position shown in the figure. By stopping the lobe imbling 17, the guide pace 2o is pressed against the catcher 21 and fixed. The guides ν to 16 are each set at a predetermined position to form a tape running path, whereby the magnetic tape 4 is wound around the one-turn head device 1 at a predetermined angle. Further, the pinch roller 8 is attached to the capstan 7K with the magnetic tape 4 sandwiched therebetween.

The magnetic tug 4 passing through the gap is wound onto a take-up sling 6 which is rotated by a reel motor (not shown).

Further, in the figure, the cleaning member 23 is attached to the rotary head device 1.
In this state, the cleaning member 23 is rotatably fixed to the arm 27 by a shaft 50, and the arm 27 is rotatably fixed to the chassis 2 by a shaft 29. The arm 27 is elastically biased about the shaft 29 by a spring (not shown) in a direction (counterclockwise direction in the drawing) in which it contacts the rotary head device 1 . The arm 28 is rotatably fixed to the chassis 2 by a shaft 32, one end engages with a protrusion of the shaft 30 on the upper surface of the arm 27, and the other end is fixed to the chassis 2 and connected to the solenoid shaft 26 from the shaft 31Vc of the solenoid 25. Rotatably connected. The solenoid shaft 26 is elastically biased by a spring 24 in a direction away from the solenoid 25. The biasing force of the spring 24 is set to be greater than the biasing force of a spring (not shown) that biases the arm 27. In addition, the figure shows the shape M in which the solenoid 25 is not connected.

For this reason, the solenoid shaft 26 is not attracted to the solenoid 25, and due to the elastic biasing force of the spring 24, the solenoid shaft 26 is not attracted to the solenoid 25.
It has come to rest at the position shown in the figure.

From this point, the arm 27 receives a force to rotate clockwise in the figure about the shaft 29 via the arm 28.

Since this force is larger than the counterclockwise elastic urging force exerted on the arm 27 by the not-shown spring, the arm 27 resists the elastic urging force of the not-shown spring and stops at the position shown in the figure. Due to this, the cleaning member 23 is separated from the rotary head device.

FIG. 12 Beam 9-Jung member 23 is rotating head device 11
C is a plan view showing a state in which they are in contact. When the solenoid 25 is energized from the state shown in Fig. 11, the solenoid shaft 26
is attracted by the solenoid 25, moves to the position shown in the figure against the elastic urging force of the spring 24, and stops. Therefore, the arm 28, which is connected to the solenoid shaft 26 by the shaft 31 at -i, rotates clockwise in the figure around the shaft 32. Due to this rotation, the arm 27 rotates counterclockwise about the shaft 29 according to the elastic urging force of a spring (not shown), and the cleaning member 23 comes into contact with the rotary head device 1 . The arm 28 rotates to the resting position in FIG. 12 and stops, but at this time one end of the arm 28 and the protrusion of the shaft 30 are separated. This slanted cleaning member 26 contacts the rotary head fcf1 with a predetermined contact force due to a predetermined elastic biasing force of a spring (not shown) that biases the arm 27. In this way, the rotary head device 1 is cleaned by the cleaning member 23.

Next, the 9-Jung device! Embodiment 1 will be explained with reference to FIGS. 1 and 2. In addition, in Figure 1.2, 2

One end of the arm 28 engages with a protrusion of the shaft 29 on the upper surface of the arm 27. The arm 27 is elastically biased by a spring 40 in the counterclockwise direction in FIG. 3 about the shaft 29, but is supported by the arm 28 and stopped at the position shown in the figure. This causes the Jung member 23 to be separated from the rotating hecht device t1.

Further, the arm 49 is rotatably supported by a shaft 46, and the shaft 46 is fixed to the chassis 2 by a base 51. One end of the arm 49 is rotatably connected to the arm 48 by a shaft 45 at the position shown in the figure.
