Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a stylus cleaner that also cleans record needles, and includes a base body that grounds the stylus cleaner on a table such as a turntable, and a base body that can be moved up and down on the base body. The recorder is divided into a main body and a main body equipped with an operating means such as a cleaning brush supported by the record stylus, and only the main body can be moved up and down according to the height of the record stylus.

(Prior Art) The height of the record needle attached to the tip of the tone arm varies depending on the model of the record player. For this purpose, as shown in FIG. 4, a base part 2 is provided to ground the stylus cleaner 1 on a table such as a turntable, and a record stylus cleaner such as a cleaning brush 3 is provided in front of the base part 2. The actuating part 4 is formed separately, and both 2 and 4 are connected via pinion racks 5 and 6, so that the actuating part 4 can be raised and lowered according to the height of the record needle by rotating the handle 7. Something has already been proposed.

(Problem to be solved by the invention) However, in this way, the stylus cleaner 1 is divided into the base part 2 and the actuating part 4 located in front of the base part 2, and only the actuating part 4 is moved up and down. As a result, the lead wires 8 wired from the base section 2 to the actuating section 4 tend to be twisted, resulting in poor contact in the electric circuit, malfunction of the drive system, or breakage. In addition, since the actuating part 4 is located in front of the base part 2 and moves up and down, the balance of the center of gravity is unstable and it tends to wobble during work. Also, dirt and foreign matter may enter the gap a between the base part 2 and the actuating part 4. There are disadvantages in that it tends to interfere with the lifting and lowering of the actuating part 4, and furthermore, the structure is complicated and there are many failures.

(Means for Solving the Problems) For this purpose, the present invention includes a power battery 25, an electromagnet 21 driven by the power battery 25, a diaphragm 23 that transmits the movement of the electromagnet 21 to the cleaning brush 13, A stylus cleaner is composed of a main body 11 provided with a switch part 14, and a base body 10 that is grounded on a stand 28 and supports the main body 11 from below. And the base body 1
0, a screw rod 17 is provided upright, a rotation operation section 15 for the screw rod 17 is provided, and the main body 11
A threaded portion 18' is provided at the center of gravity of the threaded portion 1.
8' is screwed onto the threaded rod 17, so that the main body 11 is mounted on the upper part of the base body 10 so as to be movable up and down.

(Function) According to the above configuration, by operating the rotary operation section 15, the main body 11 is moved up and down along the threaded rod 17, and the height of the cleaning brush 13 is adjusted. In this case, the threaded part 1 screwed into the threaded rod 17
8' is located at the center of gravity of the main body 11, so the main body 11
The balance of the center of gravity is good, and there is no unnecessary wobbling during work.

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

FIG. 1 is a perspective view of a stylus cleaner 9. This stylus cleaner 9 has a plate-shaped base body 10 that is grounded on a stand 28 such as a turntable.
and a main body 11 supported from below by this base body 10. A stepped protrusion 12 is formed at the tip of the main body 11, and a cleaning brush 13 is disposed on this protrusion 12. Further, a press-type switch section 14 is provided on the upper surface of the main body 11.

Reference numeral 15 denotes a rotary operation section for raising and lowering the main body 11, and it protrudes into arc-shaped recesses 16 formed on both side walls of the main body 11. As shown in FIG. is located on the base body 10, and a screw rod 17 is erected in the center thereof.
A threaded portion 18' provided at the bottom of the main body case 18 constituting the main body 11 is screwed onto this threaded rod 17, and its lower end passes through the base body 10.
It is rotatably supported by a base body 10. Therefore, when the operating portion 15 is rotated to turn the screw rod 17, the main body 11, which is screwed and supported by the screw rod 17 via the threaded portion 18', immediately moves up and down along the screw rod 17.

Inside the main body case 18 in front of the screw rod 17, a switch body 19 operated by pressing the switch part 14, a wiring board 20, an electromagnet 21, and the cleaning brush 13 and permanent magnets 22 are mounted on both front and rear ends. A thin plate-like diaphragm 23 is installed inside. Among these, the electromagnet 21 is attached to the wiring board 20 with its working pole facing downward, and the diaphragm 23 has a permanent magnet 22 facing the working pole of the electromagnet 21 so that its approximately center portion is attached to the wiring board 20. The vibration plate 23 is fixedly supported by a chassis 24 and transmits the interlocking movement of the electromagnet 21 to the cleaning brush 13. Also, the main body case 1 behind the screw rod 17
8 contains a power battery 25 that drives the electromagnet 21.
A balance weight 26 is disposed above the power battery 25 so that the screw rod 17 supports the center of gravity of the main body 11, and the screw rod 17 supports the center of gravity of the main body 11 in the X-axis direction. It is located on the neutral axis NA (see Figure 3). 27 is a record stylus attached to the tip of the tone arm, and 28 is a turntable.

This stylus cleaner 9 has the above-mentioned configuration, and when adjusting the height of the cleaning brush 13 according to the height of the record stylus 27, lightly hold the main body case 18 with your fingers and press the operating section with your fingertips. 15, the main body 11, which is screwed and supported on the threaded rod 17 via the threaded portion 18', is rotated by the threaded rod 1.
Rising or descending along 7. When the record needle 27 is inserted into the cleaning brush 13 to an appropriate depth, the switch section 14 is operated. Then, the oscillation circuit of the wiring board 20 is driven, the electromagnet 21 repeats excitation and demagnetization, the permanent magnet 22 vibrates up and down, the diaphragm 23 also vibrates up and down, and the cleaning brush 13 also vibrates up and down to clean the record stylus 27. I do. When the cleaning work is completed in this way, the switch section 14 is operated again to stop the drive. In the above handling operation, the threaded rod 17
Since it supports the center of gravity of the main body 11, it is extremely stable, and the main body 11 does not wobble during work.

Note that the threaded rod 17 does not have to support the exact center of gravity of the main body 11, and a slight deviation is allowed.The point is that the main body 11 does not need to wobble unnecessarily during work. In the present invention, the position of the center of gravity includes the approximate position of the center of gravity.

(Effects of the Invention) As described above, according to the present invention, the height of the cleaning brush 13 can be easily adjusted by moving the main body 11 up and down by operating the rotary operation section 15. In addition, since the center of gravity of the main body 11 is supported by the threaded rod 17 erected on the base body 11, the center of gravity is extremely well balanced, so there is no need to wobble unnecessarily during work.
Further, since the components such as the power supply battery 25 and the electromagnet 21 are arranged in the main body 11, electrical wiring is also extremely advantageous.
