It is. The configuration and operation of the rotation device of the television receiver according to the first embodiment will be described with reference to the drawings. Reference numeral 10 denotes a disk-shaped base, and a circular part having a depression such that a washer 50 is fitted into the center of the base 1 and the head of the self-tapping screw 60 does not protrude from the bottom surface of the base 1. There is a rotation center hole 10a having a seat.

Reference numeral 20 denotes a cabinet of a television receiver in which electronic equipment is built. The cabinet can be inserted into the rotation center hole 10 of the base 10 on the bottom surface thereof, and the cabinet 20 can freely rotate on the base 10. Rotation center hole 10 as possible
It has an outer shape slightly smaller than the inner diameter of “a”, and has a cylindrical hole in which the self-tapping screw 6 can be screwed. The height of the rotation center boss 2 is such that when the base 10 is fitted into the cabinet 20, the height slightly protrudes from a seat around the rotation center hole 10 a of the base 10.
0a.

At the bottom of the cabinet 20, there are provided a unit roller 40 having rollers 40a connected to each other in an annular shape so as to have a radius smaller than the outer shape of the base 10 around the rotation center boss 20a, and the rollers 40a. Two rails 20b having a width such that they can ride are provided. The unit rollers 40, the rollers 40a and the rails 2b constitute rolling members for smoothly rotating the cabinet 20 on the base 10. And
A sliding piece disposed on the bottom surface of the cabinet 20 at a predetermined angle α with respect to the center line X of the cabinet 20 passing through the center of the rotation center boss 20a and between the sliding surface 10b and the base 10. Seat 2 for positioning 30
0c is provided.

The sliding piece 30 is made of, for example, a non-woven fabric and has an adhesive or an adhesive on one side, and the adhesive or the adhesive is inserted into the seat 20c so that the sliding piece 30 becomes a television. It is fixed to the cabinet 20 of the receiver. FIG. 2 is a cross-sectional view showing this state.
The base 10 has the rotation center boss 20a of the cabinet 20 of the television receiver inserted into the rotation center hole 10a, and is held by the self-tapping screw 60 via the washer 50. A roller 40a is provided on a surface of the base 10 facing the bottom surface of the cabinet 20 of the television receiver.
And a sliding surface 10b on which a sliding piece 30 fixed to a seat 20c provided at the bottom of the cabinet 20 slides.

The rotating device thus constructed inserts the rotation center boss 20a provided on the bottom surface of the cabinet 20 into the rotation center hole 10a of the base 10 as described above, and It is held by a tap screw 60. Rotation center boss 20a and rotation center hole 10a
Has a slight clearance, so that the base 10 can freely rotate around the rotation center boss 20a. Further, between the rail 20b provided on the bottom surface of the cabinet 20 and the pedestal 10c provided on the base 10, rollers 40a of unit rollers 40 are sandwiched, and the cabinet 20 is centered on the rotation center boss 20a. 4
0a enables smooth rotation. In this state, the full load of the cabinet 20 containing the electronic device is applied to the rollers 40a, but is slightly larger than the distance between the seat 20c provided on the bottom surface of the cabinet 20 and the sliding surface 10b of the base 10. By fixing the thick sliding piece 30 to the seat 20 c provided on the bottom surface of the cabinet 20, the load of the cabinet 20 is distributed to the rollers 40 a of the unit roller 40 and the sliding piece 30.

The sliding piece 30 has elasticity because it is made of a nonwoven fabric, and contracts when a load is applied. Therefore,
By changing the thickness of the sliding piece 30, the load applied to the sliding piece 30 can be adjusted. When the cabinet 20 of the television receiver is rotated, the sliding piece 30
Then, the sliding surface 10b of the base 10 is rubbed, and a frictional force against the rotation is generated. The frictional force becomes a static force that stops at a desired arbitrary position when the cabinet 20 containing the electronic device is rotated.

For example, the thickness of the sliding piece 30 is adjusted by the seat 20 c provided on the bottom surface of the cabinet 20 and the sliding surface 1 of the base 10.
0b, the sliding piece 30
Is reduced, the frictional force between the sliding piece 30 and the sliding surface 10b is reduced, the rotation of the cabinet 20 is reduced, and the static force is also reduced. Conversely, if the thickness of the sliding piece 30 is made larger than the distance between the seat 20c provided on the bottom surface of the cabinet 20 and the sliding face 10b of the base 10, the load applied to the sliding piece 30 increases. Sliding piece 30
And the frictional force between the sliding surface 10b and the cabinet 2
The rotation of 0 becomes heavier and the resting force becomes larger. Therefore, by optimally setting the thickness of the sliding piece 30, the cabinet 20 can rotate more smoothly by the rollers 40a, and
The slide piece 30 can be stopped at any desired position.

Accordingly, since the sliding surface 10b of the base 10 is slid by the nonwoven fabric of the first piece 30a, the rotating operation of the cabinet 20 rotatably mounted on the base 10 is performed smoothly. . However, when the sliding piece 30 is worn due to sliding of the first piece 30a made of a non-woven fabric or set by a load of a cabinet including a built-in electronic device, a certain thickness is required. It will be expensive. In order to solve the problem, in the present embodiment, the thickness of the nonwoven fabric of the sliding piece 30 is reduced, and the first piece 30a made of the nonwoven fabric and the second piece made of the hard rubber are used to compensate for the reduced thickness with hard rubber. Piece 30b is stuck. Hard rubber is relatively inexpensive and has excellent workability and cushioning properties.

That is, the friction coefficient of the sliding surface 10b can be changed by arbitrarily changing the surface roughness of the sliding surface 10b provided on the base 10, and the nonwoven fabric of the sliding piece 30 used in the third embodiment can be changed. The frictional force between the first piece 30a made of and the sliding surface 10b is adjusted. For example, when the base 10 is formed by plastic molding, the surface of the sliding surface 10b can be easily adjusted by applying a satin finish or a graining process to the sliding surface of the mold and changing the surface roughness. Can be changed. Therefore, the force required for rotating the cabinet and the frictional force for stopping the cabinet at a desired position can be arbitrarily set.
