Description

[Detailed description of the invention] This invention is an ultrasonic record stylus cleaner that cleans the record stylus by immersing it in a small amount of cleaning liquid while attached to the pink amplifier arm and applying ultrasonic vibration to the cleaning liquid. In particular, the present invention has the added advantage of making it possible to attach and detach a small-sized cleaning tank filled with cleaning liquid to a hand-held case, thereby facilitating filling, discharging, replacing, etc. of cleaning liquid.

Playing a record with dust, oil, and fats attached to the record stylus not only causes noise but also damages both the sound groove of the record and the record stylus.

For this reason, conventionally, before playing a record, the record stylus is cleaned with a special brush impregnated with cleaning liquid such as alcohol, but the cleaning process is troublesome and the cleaning effect is poor. There were also drawbacks, such as contact with the mounting part, etc., causing damage and the needle breaking.

The present invention solves these drawbacks, and is designed to include a small cleaning tank that can be attached to and removed from a handheld case, and to electrically connect the ultrasonic vibrator to the output end of the oscillation unit.

An embodiment of the present invention σ) will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a hand-held case, which has an elongated shape that can be held by hand and carried to the lower part of the record needle of the pink amplifier arm a.The tip thereof is formed into an arcuate surface 2, and the upper surface of the tip has an inner diameter of about 20 mm. , forming a fitting hole 3 with a depth of about 10 sn,
Furthermore, a pair of receiving terminals 4 are exposed and provided at the bottom of the fitting hole 3σ).

In addition, a switch rotor is installed on the top surface that can be turned on and off by sliding or seesaw operation.

A unit board 8 on which an oscillation circuit unit 7 is mounted is mounted inside the handheld case 1, and the output end of the unit I is electrically connected to the receiving terminal 4 by a lead wire.

Inside the handheld case 1, open the bottom cover 5 and insert the battery 10.
Attach the battery terminal 9 consisting of a fixed terminal and a spring terminal that can be inserted and engaged, and turn on the switch to connect the battery 1.
0 to the oscillation circuit unit 7.

Note that power may be supplied to the oscillation circuit unit 7 by inserting a cord terminal of a known σ converter connected to a power line into the hand-held case 1.

Reference numeral 11 denotes a small cleaning tank which is fitted almost tightly into the above-mentioned fitting hole 3 so as to be able to escape from the hand-held case 1σ), so that the collar 12 is engaged with the top surface of the case 1, and a diaphragm acts on the inner bottom of the tank. The ultrasonic transducer 13 fixed in a sealed container 15 is placed inside the container 15.
A pin-shaped σ fixed together with the oscillator 13 and protruding from the bottom of the vibrator 13)
A pair of electrodes 14 are made to penetrate the sealed container 15 and the small cleaning tank 11 in a watertight manner and protrude downward.

The electrode 14 is designed to fit into the receiving terminal 4.

The present invention is based on a small cleaning tank 1 that is removed from a handheld case 1.
1 is filled with a cleaning liquid 16 such as an alcohol solution, and then tightly fitted into the fitting hole 3 of the handheld case 1 as shown in FIG. After fixing the cleaning tank 11, use the hand-held case 1 to gently transport it to the bottom of the record needle attached to the pink amplifier arm a as shown in Figure 4, immerse the record needle in the cleaning solution, and then remove the oscillation circuit. Power is supplied to the unit 7, and ultrasonic vibrations are applied to the cleaning liquid 16 via the ultrasonic vibrator 13 and the sealed container 15 to clean the record stylus.

The present invention is based on the configuration illustrated above, and the small cleaning tank 11 filled with the cleaning liquid 16 has an ultrasonic transducer 13 inside it.
is fixed, and an electrode 14 is protruded from the bottom surface of the cleaning tank 11. When the electrode 14 is fitted into the fitting hole 3 of the handheld case 1, the electrode 14 is inserted into the receiver attached to the bottom of the fitting hole 3 on the handheld case side. This compact cleaning device has a structure in which the cleaning tank 11 is fitted into the terminal 4 to automatically create an electrical connection between the ultrasonic vibrator 13 and the output side of the oscillation circuit unit 7, and at the same time fix the cleaning tank 11 to the handheld case 1. Since the tank 11 can be removed from the hand-held case 1 at will, filling the cleaning liquid, returning and discharging the washing-liquid bottle, or replacing the cleaning liquid can be carried out at a location away from the hand-held case 1. Since the vibrator 13 is fixed inside, a sufficient cavity shoring effect of the cleaning liquid can be generated despite the small size.

In addition, it is possible to drive the oscillation circuit 7 with a small amount of power supply and apply ultrasonic cavitation to the cleaning liquid, so it can only be used for ultrasonic cleaning of record needles with a small surface area. amplifier arm a
Since the small cleaning tank 11 can be carried to the underside of the record needle with the hand-held case 1 while still attached to the record needle, washing the needle is no different than when using the dedicated brush mentioned above, and the entire immersion surface of the record needle is cleaned. Since it can be cleaned without the need for other operations, the completeness of cleaning and the ease of use are not comparable to brushes, and it also has various effects such as being small and lightweight and extremely easy to handle.
