At the same time, it is fitted into a groove 12 provided in the case 1.1'.

Reference numeral 13 denotes an electrostatic voltmeter electrically connected to the current collector plate, and a scale plate 5 is attached to the electrostatic voltmeter 13 so as to be exposed from the outer surface of the cases 1 and 1'.

FIG. 4 shows the internal structure of the needle-shaped discharge electrode section 4.

Figure 7 shows an electrical circuit diagram, and 23 is a power source battery 9.
switch connected to, 24. 24' is input terminal, 25
is the capacitor 2 connected between the input terminals 24 and 24'
A dividing resistor 6.27 is connected in parallel to the capacitor 25, and a light emitting diode 28 and a resistor 29 are connected to the connection point of the dividing resistor 26.27.

A capacitor 30 is connected to the resistor 29. One end of the capacitor 30 is connected to the base of the transistor 31, and the other end is connected to the primary coil 7a of the high voltage transformer 7.

Further, the primary coil 7a of the high voltage transformer 7 is connected to the collector of the transistor 31.

The emitter of transistor 31 is connected to input terminal 24'.

32 is a secondary side terminal of the high voltage transformer 7.

In the above circuit configuration, the operation of the static electricity eliminator of the present invention will be explained.

When a DC voltage is applied between the input terminals 24 and 24' via the switch 23, the base current is supplied to the transistor 31 by the resistors 26 and 27, and the current flows through the primary coil 7a of the high voltage transformer 7 and the capacitor 30. Positive feedback is provided and the high voltage transformer 7 oscillates.

The secondary coil 7b of this high voltage transformer 7 has several thousand times as many turns as the primary coil 7a, and generates a high voltage.

A high-voltage AC voltage is generated at the secondary terminal 32 of the high-voltage transformer 7, and is supplied to the plurality of discharge electrodes 19 shown in FIG.

When this supply applies a potential to the discharge electrode 19 and forms an unequal electric field, corona discharge starts from the point where the electric field becomes stronger.

This corona discharge decomposes molecules in the air into ionic molecules, and these ionic molecules combine with opposite polarity charges on a record or the like to neutralize static electricity.

In addition, when generating ionized air to remove static electricity from the plurality of discharge electrodes 19, the switch 23 is closed by simply pressing the push button 2 shown in FIG. 1, and the ionized air can be generated. Therefore, for example, when removing static electricity from a resin flat plate such as a record disc that is charged with static electricity, press the push button 2 with the current collecting plate 14 in the static electricity eliminator of the present invention facing the resin flat plate such as a record disc.
If the switch 23 is closed by pressing , the static electricity can be easily removed.

Furthermore, by using the scale plate 5 of the electrostatic voltmeter 13 built into the cases 1 and 1', it is possible to easily check whether there is a charge or whether static electricity has been removed by bringing the current collecting plate 14 close to the charged object.

The support plate 11, which also supports the current collector plate 14 and is attached to the opening 10 of the case 1゜1', is made of polypropylene with high insulation resistance. When removing static electricity by holding the current collecting plate 14 facing a resin flat plate such as a record, the electric charge on the current collecting plate 14 is removed from the case 1, 1' made of ABS resin.
Even if an attempt is made to ground the support plate 11 through the support plate 11, the insulation resistance of the support plate 11 is very large, so the grounding as described above will not occur.

As described above, according to the present invention, a low-voltage power supply section, an oscillation circuit unit connected to the low-voltage power supply section, a high-voltage transformer, and a discharge electrode section that generates ionized air to remove static electricity by operating a switch are provided. Since the static electricity eliminator itself can be made compact, static electricity charged on a resin flat plate such as a record disc can be easily removed by simply operating a switch.

In addition, the support plate that supports the current collector plate of the discharge electrode section that is attached to the ABS resin case is made of Bonpropylene, which has a high insulation resistance. When removing static electricity by holding it in your hand, you can prevent the electric charge on the current collector plate from being grounded through the ABS resin case, and as a result, the electrostatic voltmeter always operates reliably. can be made to do so.
