Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a stylus cleaner for cleaning a record stylus, and in particular, to a means for adjusting the height of a cleaning brush according to the height of a record stylus. Regarding.

(Prior art) The height of the record stylus attached to the tip of the tone arm varies depending on the model of the record player, but in order to accommodate this, a base for placing the stylus cleaner on a turntable etc. It is known to be divided into an operating section and an operating section provided with cleaning tools such as a cleaning brush and an ultrasonic cleaning tank, and the operating section can be moved up and down. FIG. 6 shows a conventional stylus cleaner of this kind, and this stylus cleaner 1 consists of a base part 2 placed on a table such as a turntable, and an operating part 4 equipped with a cleaning brush 3. It's on. A rack 5 is protruded from the rear end of the actuating part 4. This rack 5 is engaged with a pinion 6 attached to the tip of the base part 2, and the actuating part 4 is raised and lowered by rotating the handle 7. I was starting to let them do it.

(Problem to be solved by the invention) However, when this device is driven, the actuating part 4
vibrates in the vertical direction, but since the rack 5 is designed to move in the vertical direction, that is, in the same direction as the vibration direction, the pinion 6 that meshes with the rack 5 gradually loosens with the vibration, and the actuating part 4 slides off. The cleaning brush 3 moves away from the record stylus, making it difficult to perform the cleaning operation.
Since a locking structure for positioning the actuating part 4 at an arbitrary position is required separately, the structure becomes complicated.

In addition, in order to insert the record stylus into the cleaning brush to the best depth for cleaning, it is necessary to be able to finely adjust the height of the operating section. Since the amount of rotation of the circumferential surface of the pinion 6 is equal to the amount of rotation of the circumferential surface of the pinion 6, it is difficult to finely adjust the height of the cleaning tool 3 by slightly moving the operating portion 4. Furthermore, since the actuating portion 4 is cantilevered by the base portion 2 via the rack pinions 5 and 6, there is a problem in that the support of the actuating portion 4 becomes unstable.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a stylus cleaner in which the height of the cleaning brush is less likely to change unnecessarily during operation, and the height of the cleaning brush can be easily finely adjusted.

(Means for Solving the Problems) For this purpose, the present invention divides the main body into a base portion 9 and an actuating portion 11, and the base portion 9 includes a power source battery.
8 and a switch section 16, and an electromagnet 26 driven by the power supply battery 18 in the operating section 11, a cleaning brush 10, and an electromagnet 2.
A diaphragm 28 is disposed to transmit the motion of 6 to the cleaning brush 10. Further, a threaded rod 22 is provided upright on the base portion 9, a rotation operating portion 24 for the threaded rod 22 is provided, and a threaded portion 23 is provided in the operating portion, and this threaded portion 23 is connected to the threaded rod 22. By screwing the actuating part 11 onto the base part 9, the actuating part 11 can be moved up and down.

(Function) According to the above configuration, the height of the cleaning brush 10 can be easily adjusted by moving the operating section 11 up and down by operating the rotation operating section 24. Further, since the means for raising and lowering the actuating part 11 is composed of a threaded rod 22 provided upright on the base part 9 and a threaded part 23 screwed thereto, the actuating part 11 can be raised and lowered during work.
Even if the cleaning brush 1 vibrates, the operating part 11 does not easily slip down unnecessarily, and the cleaning brush 10 maintains a predetermined height. Furthermore, since the amount of elevation of the actuating part 11 is determined by the thread pitch of the screw rod 22, by reducing the thread pitch, the height of the cleaning brush 10 provided on the actuating part 11 can be finely adjusted.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the stylus cleaner, and FIGS. 2 and 3 are perspective views of a base portion and an operating portion, respectively.
Base part 9 placed on a table such as a turntable
and an operating section 1 equipped with a cleaning brush 10.
It is divided into 1 and 1. Key-shaped guide grooves 12 formed in the vertical direction on both sides of the tip of the base portion 9
By inserting the hook-shaped protrusions 13 formed on both sides of the rear end of the actuating part 11 so as to be able to move up and down, the actuating part 11 is inserted into the base part 9 so that it can move up and down.
In order to ensure close contact between the two parts 9 and 11, an arc-shaped convex part 14 is formed on the distal end surface of the base part 9, and a concave part 15 corresponding to the convex part 14 is formed on the rear end surface of the actuating part 11. , the concave and convex portions 14 and 15 are brought into close contact with each other. Reference numeral 16 denotes a switch section provided on the upper surface of the base section 9, and when pressed, a drive system is driven and the cleaning brush 10 disposed at the tip of the operating section 11 is driven.

A balance weight 17, a power battery 18, and a switch body 19 are installed inside the rear part of the base part 9 (see FIG. 4), and a mounting plate 20 extending toward the operating part 11 is provided at the bottom of the base part 9. It is extended and the mounting plate 2
A threaded rod 22 is rotatably installed in a mounting hole 21 formed at 0. This threaded rod 22 is the operating part 1
1, and is threaded at a predetermined pitch in a direction perpendicular to the vertical direction. This threaded rod 22 is screwed onto a threaded portion 23 provided at the bottom of the actuating portion 11 to support the actuating portion 11. When the operating section 24 is rotated, the operating section 11 moves up and down along the threaded rod 22.

As shown in FIG. 5, the threaded rod 22 is located at the center of the rotation operation section 24, but recesses 25 are formed in both side walls of the operation section 11 to facilitate rotation operation of the operation section 24. The operating portion 24 slightly protrudes laterally from this recessed portion 25. In this configuration, by lightly holding both side walls of the base portion 9 between the thumb and middle finger, the rotary plate 24 can be easily rotated with the index finger (see the chain line in FIG. 1).

Built into the actuator 11 is a well-known drive system, including an electromagnet 26 driven by an excitation circuit of a circuit board 27, a cleaning brush 10 at its tip, and a permanent magnet 29 at its rear end. The electromagnet 26 and the diaphragm 28 are attached to a chassis 30.
The electromagnet 26 and the permanent magnet 29 are placed opposite each other with a slight gap. 31 is the tone arm, 3
2 is a record needle.

This stylus cleaner 8 is constructed as described above, and when adjusting the height of the cleaning brush 10 in accordance with the height of the record stylus 32 attached to the tip of the tone arm 31, the operating section 24 is used to adjust the height of the cleaning brush 10. The actuating portion 11 is raised and lowered by rotating the actuating portion 11. Since the operating portion 24 protrudes from the recesses 25 formed in both side walls of the actuating portion 11 as described above, the rotating operation can be easily performed. When the threaded rod 22 is rotated by the rotation operation of the operating portion 24, the actuating portion 11, which is screwed and supported by the threaded rod 22 through the threaded plate 23, moves up and down. When adopted, the amount of elevation of the actuating part 11 is determined by the screw pitch formed in the threaded rod 22, so it can be made much smaller than the amount of rotation of the threaded rod 22, and therefore, precise fine movement of the actuating part 11 is possible. Thus, the height of the cleaning brush 10 can be finely adjusted according to the height of the record stylus 32.

Now, by adjusting the height of the actuating part 11 through the above operation, the record needle 32 is moved to the cleaning brush 1.
0 to the optimum depth for cleaning, then operate the switch section 16. Then, the oscillation circuit of the circuit board 27 starts driving, the electromagnet 26 repeats excitation and demagnetization, and in response, the permanent magnet 29 vibrates up and down, and the cleaning brush 10 attached to the tip of the diaphragm 28 also vibrates up and down. Then, the record needle 31 is cleaned.

Now, with the vibration of the diaphragm 28, the actuating part 11 also slightly vibrates up and down, but the rotation direction of the threaded rod 22, which constitutes the means for raising and lowering the actuating part 11, is
Since the direction is perpendicular to the vibration direction of the actuating part 1
1, the screw rod 22 loosens due to the vibration of the actuator 11.
The cleaning brush 1 will not fall off.
0 is maintained at the initially set height, and cleaning of the record needle 32 is reliably carried out to the end.

(Effect of the invention) As explained above, the present invention has the main body at the base part 9.
A power supply battery 18 and a switch part 16 are arranged on the base part 9 side, and an electromagnet 26 driven by the power supply battery 18 and a cleaning part are provided on the operation part 11 side. A vibration plate 28 is provided to transmit the motion of the brush 10 and the electromagnet 26 to the cleaning brush 10, and a threaded rod 22 is provided upright on the base portion 9, and a rotation operation portion 24 for the threaded rod 22 is provided. , and by providing a threaded portion 23 on the operating portion and screwing this threaded portion 23 onto the threaded rod 22, the operating portion 11 is mounted on the base portion 9 so as to be movable up and down. The height can be easily adjusted. Moreover, since the means for raising and lowering the actuating part 11 is composed of the threaded rod 22 erected on the base part 9 and the threaded part 23 screwed into this, even if the actuating part 11 vibrates during work, The operating portion 11 is unlikely to slip down unnecessarily, and the cleaning brush 10 is maintained at a predetermined height. In addition, the amount of elevation of the actuating part 11 is determined by the screw rod 2.
The height of the cleaning brush 10 provided in the operating section 11 can be finely adjusted by reducing the screw pitch. Furthermore, since the switch section 16 is provided on the base section 9 side, even if force is applied when operating the switch section 16, the vertical state of the operating section 11 will not be affected.
