Abstract

PURPOSE:To smoothly rotate a rotary part mainbody and to improve adjustment operability by fitting a bearing to a recessed part and installing an operation piece, a part of which is inserted into the hole part of the bearing and the other of which covers the surface of the bearing. CONSTITUTION:The rotary part mainbody 4 where the recessed part 8 which fits the bearing 7 to a cylindrical surface is installed and where an axis part 5 which is fitted to a jog shuttle 2 is installed is given. The bearing 7 is fitted to the recessed part 8, and the operation piece 9, a part of which is inserted into the hole part of the bearing 7 and the other part covers the surface of the bearing is given. Consequently, the bearing 7 fitted to the lower part of the operation piece 9 rotates between the rotary part mainbody 4 even if a finger is brought into contact with the operation piece 9 to rotate it. Thus, the rotary part mainbody 4 can smoothly be rotated without the occurrence of friction on the finger.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a rotating shaft for adjustment operation used in a tuning section of a television receiver, audio equipment, or the like.

BACKGROUND ART In recent years, there has been a demand for individualization of electrical products such as television receivers and audio equipment, and greater emphasis has been placed on improving design and operability.

An example of the above-mentioned conventional rotating shaft for adjustment operation will be described below with reference to the drawings.

FIG. 3 shows a perspective view of a conventional rotating shaft. In Figure 3, 1 is a printed board, 2 is a jog shuttle,
3 is a panel, 4 is a rotating part body, 5 is a shaft part, and 6 is an operating part.

A jog shuttle V2 is fixed to a printed circuit board 1 by soldering, a shaft 6 is attached to the jog shuttle 2, and the surface of the rotating body 4, which is integrally formed with the shaft 5, is a spring) V3. It is located on the same level or slightly protruding from the hole, and the operating part 6 is provided with an appropriate indentation on the surface of the rotating part main body 4 so that it can be easily touched by fingers. .

The operation of the rotating shaft configured as described above will be described below.

To rotate the jog shuttle 2, touch the operating section 6 with your finger and rotate the rotating section main body 4 to rotate the shaft section 6.
The jog shuttle /I/2 connected to the motor will rotate.

Problems to be Solved by the Invention However, with the above configuration, when rotating the rotating part main body 4, friction occurs between the fingers and the operating part 6, and as a result, the operability during rotation and the contact feel of the fingers are affected. It had the problem of not being good.

In view of the above-mentioned problems, the present invention provides a rotating shaft that can improve the operability when rotating the rotating shaft, reduce the friction between the fingers and the operation part, and improve the touch feel. be.

Means for Solving the Problems In order to solve the above problems, the rotating shaft of the present invention includes a rotating body having a cylindrical surface provided with a concave portion for mounting a bearing, and a shaft portion for mounting on a jog shuttle. A bearing is mounted in the recess, and an operating piece is provided, a part of which is inserted into the hole of the bearing, and the other part of which covers the surface of the bearing.

With the above-described configuration, the present invention has the above-mentioned configuration, so that even if the finger touches the operating piece and rotates, the bearing attached to the lower part of the operating piece rotates between the main body of the rotating part, so that the finger does not experience any friction. The main body of the rotating part can be rotated smoothly.

Embodiment Hereinafter, a rotating shaft according to an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 shows a perspective view of a rotating shaft in an embodiment of the present invention.

FIG. 2 is a perspective view showing the assembly specifications of the rotating shaft in one embodiment of the present invention.

In Figure 2, 1 is a printed board, 2 is a jog shuttle, 3 is a panel, 4 is a rotating body, and 5 is a jog shuttle)/L
2 is a shaft part for mounting the rotating part main body 4, 7 is a bearing, 8 is a recessed part for mounting the bearing 7 on the rotating part main body 4, and 9 is a recessed part for mounting the rotating part main body 4. This is an operation piece that can be operated by touching it. Operation piece 9
The shaft portion thereof is inserted into the hole portion of the bearing 7 and installed in the recess 8, and the surface plate portion covers the bearing 7 and becomes substantially flush with the surface of the rotating part main body 1.

The rotating shaft configured as above is shown in Fig. 1 below.
Its operation will be explained using FIG. In Figure 2,
A bearing 7 installed between the operating piece 9 and the rotating part main body 40
Therefore, when the operating piece 9 is brought into contact with a finger and rotated, the operating piece 9 does not rotate, the bearing 7 rotates, and the rotating part main body 4 rotates.

As described above, according to this embodiment, while the recess 8 for mounting the bearing 7 is provided on the cylindrical surface, the jogshaft)/
It comprises a rotating part main body 4 provided with a shaft part 6 to be attached to l/2,
While the bearing 7 is installed in the recess 8, the operation piece 9 is partially inserted into the hole of the bearing 7 and the other part covers the bearing surface, so that the operation piece 9 and the finger can be connected to each other. Friction is eliminated, thereby allowing the rotating section main body 4 to rotate smoothly.

Effects of the Invention As described above, according to the present invention, while a recessed portion for mounting a bearing is provided on a cylindrical surface, a jogshaft) tV
The rotating part main body is provided with a shaft part to be mounted on the rotating part body, and a bearing is mounted in the recessed part, and an operating piece is provided in which a part is inserted into the hole part of the bearing and the other part covers the surface of the bearing. As a result, there is no friction between the operating piece and the fingers that come into contact with it, which allows the main body of the rotating part to rotate smoothly, thereby improving the adjustment operability and the quality of the product itself.
