[1] Example FIG. 1 shows the appearance of the facial facial device 1 of the embodiment. FIG. 1A shows only the appearance of the facial device 1, and FIG. 1B shows a state in which the facial device 1 is covered with cotton 70. FIG. 2 shows the front, side, and back of the facial device 1. FIG. 2A shows the front surface, FIG. 2B shows the side surface, and FIG. 2C shows the back surface.

The facial treatment device 1 is a device that mainly applies beauty treatment to the user's face, and is an example of the "beauty treatment device" of the present invention. The facial device 1 includes a head portion 10 and a main body 50. The head portion 10 is a portion pressed against the user's skin. The main body 50 is a rod-shaped portion having a first surface 51, two second surfaces 52, and a third surface 53, both of which are elongated surfaces, and is a portion gripped by the user. The main body 50 is an example of the "grip portion" of the present invention. The head portion 10 is provided at one end of the main body 50 in the longitudinal direction A1 of the first surface 51.

In the facial toning device 1, the side facing the first surface 51, that is, the side provided with the head portion 10, faces the side surface, and the side facing the second surface 52 faces the third surface 53. The back is the back. The first surface 51 is provided with an operation button 54 operated by the user.
The operation button 54 may be a touch-type switch displayed on the liquid crystal panel or may be a mechanical switch. The operation button 54 accepts an operation of selecting the operation mode of the facial device 1 and an operation of starting the operation in the selected operation mode.

In this embodiment, the configuration related to the operation in the cleansing mode for removing stains on the skin while performing deep heat to warm the deep layers of the skin will be described. The head portion 10 includes an electrode portion 20, a columnar portion 30, and a stopper 40. Both the above-mentioned deep heat and dirt removal are performed by passing an electric current through the skin. The electrode portion 20 is a portion provided with an electrode to which a voltage for passing an electric current is applied to the skin in deep heat and dirt removal. Hereinafter, the voltage for deep heat is referred to as "first voltage", and the voltage for removing stains is referred to as "second voltage". The electrode portion 20 includes a first electrode 21 and a second electrode 22.

The first electrode 21 is an electrode having a circular outer circumference, and in this embodiment, it is an annular electrode having an opening in the center. The second electrode 22 is a ring-shaped electrode having an opening in the center, is concentric with the first electrode 21, and is arranged outside the outer periphery of the first electrode 21. Due to these shapes and arrangements, the distance between the first electrode 21 and the second electrode 22 is constant anywhere on the circumference. A high frequency voltage (a voltage indicating a high frequency, also referred to as an RF (Radio Frequency) voltage) is applied between the first electrode 21 and the second electrode 22 as the above-mentioned first voltage.

The columnar portion 30 is a columnar portion having a circular cross section, and has a cylindrical shape in this embodiment. The columnar portion 30 has a bottom surface 31 and a side surface 32, and an electrode portion 20 is attached to the bottom surface 31. The bottom surface 31 is an example of the “mounting surface” of the present invention. The columnar portion 30 has a housing that forms an internal space for arranging wiring and the like, and the housing is formed by using an electrically insulating material such as plastic, non-metal, or ceramic. As a result, even if a voltage is applied to the electrode portion 20, no current flows through the housing of the columnar portion 30, and current flows through the user's skin.

A ring 60 is fitted in the columnar portion 30. The ring 60 is a ring-shaped magnetic material having an inner diameter larger than the outer circumference of the columnar portion. The ring 60 is made of a material exhibiting ferromagnetism such as iron, cobalt, nickel, alloys thereof or ferrite. The stopper 40 is connected to the opposite side of the bottom surface 31 of the columnar portion 30, and is a portion that stops the ring 60 when the ring 60 is fitted into the columnar portion 30.

The stopper 40 has a magnet portion 41 and a notch portion 42. Each of the magnet portions 41 has four magnets embedded in the stopper 40 in this embodiment. As shown in FIG. 1 (b), the bottom surface 31 of the columnar portion 30 is covered with cotton 70 obtained by molding cotton fibers into a sheet shape. Cotton 70 is an example of the "porous coating" of the present invention. In this way, the cotton 70 covering the bottom surface 31 is sandwiched and fixed by the ring 60 attracted to the magnet portion 41 and the columnar portion 30 (specifically, the side surface 32 thereof).

The stopper 40 has an annular shape, but a notch 42 is formed by cutting off a part of the outer peripheral side thereof.
FIG. 3 shows the stopper 40 and the like in an enlarged manner. In FIG. 3, the first electrode 21, the second electrode 22, and the ring 60 are hatched for easy identification. The first electrode 21, the second electrode 22, the columnar portion 30, and the stopper 40 (circular outer peripheral portion) are all arranged so as to be concentric with the center point P1 as the center.

Further, the ring 60 fitted in the columnar portion 30 is also in a state of being substantially concentric with these. Assuming that the direction from the center point P1 toward the outer circumference is the radial direction A2, the notch portion 42 has a smaller radial dimension than the circular outer circumference of the ring 60 fitted in the columnar portion 30 of the stopper 40. It is a part. That is, the dimension B1 in the radial direction A2 on the outer circumference of the ring 60> the dimension B2 in the radial direction A2 in the notch 42 of the stopper 40.

By providing the notch 42, the ring 60 in which the cotton 70 is fixed can be pushed from the back side, so that the ring 60 can be easily removed as compared with the case where the notch 42 is not provided. The columnar portion 30, the stopper 40, and the ring 60 may be shaped so as to be able to fix the cotton 70. For example, the columnar portion may be in the shape of a truncated cone whose cross section becomes smaller as it is closer to the bottom surface 31. Further, the stopper may be in the shape of a polygonal plate, or may be in the shape of a disk having a radius smaller than the outer circumference of the ring 60 and having no notch (still stopping the ring 60). Because the ring 60 can be pushed from the back side).

The portion of the fixed cotton 70 that covers the bottom surface 31 of the columnar portion 30 is a contact portion 71 that comes into contact with the user's skin. The contact portion 71 is a portion to which stains on the skin adhere when the head portion 10 of the facial device 1 operating in the cleansing mode is pressed against the user's skin. In the cleansing mode, the contact portion 71 is impregnated with a cleansing lotion to make it easier to remove stains.

A third electrode 55 is provided on the third surface 53 of the main body 50. The third electrode 55 is an oval-shaped electrode extending from one end to the other in the longitudinal direction A1 of the third surface 53. Since the third electrode 55 is provided in such a wide range, the hand of the user who holds the main body 50 always comes into contact with the third electrode 55. The above-mentioned second voltage (voltage for removing dirt) is applied between the third surface 53 and the electrode portion 20.

As the second voltage, a DC voltage or a pulse voltage is used. The direct current voltage is a voltage having a constant magnitude and direction and a direct current flowing when applied. It should be noted that even if the magnitude is not constant and fluctuates slightly, it may be regarded as a DC voltage as long as the direction is constant. Further, the pulse voltage means a voltage when a period in which a DC voltage is applied and a period in which a DC voltage is not applied are alternately repeated. Hereinafter, the case where the pulse voltage is used as the second voltage will be described, but a DC voltage may be used instead of the pulse voltage.

FIG. 4 shows the configuration of the electronic circuit of the facial device 1. In addition to the electrode unit 20 having the first electrode 21 and the second electrode 22 and the third electrode 55, the facial device 1 includes a first power supply unit 81, a second power supply unit 82, a voltage control unit 83, and resistance measurement. A control circuit board 80 having a unit 84 is provided. The control circuit board 80 is a board provided with a circuit for controlling voltage, and is composed of electronic elements (for example, a capacitor, a coil, an IC chip, a memory, etc.).

The first power supply unit 81 applies a high frequency voltage as the first voltage between the first electrode 21 and the second electrode 22. The first power supply unit 81 has an oscillation circuit that generates a high frequency voltage, a booster circuit that boosts the oscillated voltage, and the like, and applies a high frequency voltage of, for example, about 1 [MHz] to 4 [MHz]. When the head portion 10 in a state where the high frequency voltage is applied by the first power supply portion 81 is pressed against the user's skin, a high frequency current flows through the skin through the lotion soaked in the cotton 70.

Since the distance between the first electrode 21 and the second electrode 22 is constant anywhere on the circumference as described above, the distance between the first electrode 21 and the second electrode 22 is uniform. High frequency current flows. Therefore, it is possible to apply a high frequency current over a wide range and evenly to the user's skin located between the first electrode 21 and the second electrode 22, the heat generation area of the user's skin is wide, and the stimulation by energization is generated. Become even. As a result, compared to the case where a high-frequency current is passed between spherical electrodes, for example, the amount of heat generated per unit area of the skin becomes smaller, and the high-frequency current, which has been a problem in the past, makes it easier for the skin to have heat locally. It is designed to prevent the user from feeling uncomfortable.

The second power supply unit 82 has an oscillation circuit for generating a pulse voltage, a booster circuit for boosting the oscillated voltage, and the like, and has an electrode unit 20 (one or both of the first electrode 21 and the second electrode 22) and a third. A pulse voltage is applied between the electrodes 55. When the user grasps the main body 50 of the facial device 1 and presses the head portion 10 against the skin, a weak direct current is transmitted into the user's body through the hand touching the third electrode 55 and the lotion soaked in the cotton 70. Current flows.

In the cleansing mode, the second power supply unit 82 applies a pulse voltage to the electrode unit 20 so that the third electrode 55 side has a negative potential. As a result, the skin side has a negative potential with respect to the head portion 10, and so-called ion derivation is performed in which the waste products and stains that are negatively charged and adhere to the skin are adsorbed on the cotton 70. In the facial device 1, deep heat by a high frequency voltage and dirt removal by a pulse voltage are alternately performed.

The voltage control unit 83 controls the high frequency voltage applied by the first power supply unit 81 by controlling the first power supply unit 81, and the pulse voltage applied by the second power supply unit 82 by controlling the second power supply unit 82. To control. The voltage control unit 83 is an example of the “control unit” of the present invention. The voltage control unit 83 controls so that the first period in which the high frequency voltage is applied and the second period in which the pulse voltage is applied alternate. The voltage control unit 83 controls, for example, to make both the first period and the second period have the same length (for example, about 5 to 15 seconds).

Further, the voltage control unit 83 uses the measurement result by the resistance measurement unit 84 to control both voltages.
The resistance measuring unit 84 measures the resistance value between the first electrode 21 and the second electrode 22. In this embodiment, the resistance measuring unit 84 measures the electric resistance (resistance) as a resistance value. As shown in FIG. 1 (b), the resistance measuring unit 84 has the first electrode 21 and the first electrode 21 and the state in which the cotton 70 is fixed and soaked with the cosmetic water (the state before the head portion 10 is pressed against the user's skin). Since a current flows through the lotion due to the high frequency voltage applied between the second electrodes 22, the resistance value of the lotion is measured. Then, in a state where the head portion 10 is pressed against the user's skin, an electric current flows through the cosmetic water to the user's skin, so that the resistance measuring unit 84 determines a resistance value indicating the combined resistance of the cosmetic water and the user's skin. Measure.

This resistance value (electrical resistance) changes depending on the skin condition of the user, the type of lotion, and the like.
For example, it is known that when a high-frequency current is applied to the skin of the human body, the skin generates heat and the impedance inside the skin gradually decreases as the temperature of the skin rises. Therefore, as the temperature of the skin rises, the amount of current flowing between the first electrode 21 and the second electrode 22 increases, and the measured resistance value decreases. The resistance measuring unit 84 measures the resistance value at a predetermined time interval (for example, every 0.5 seconds), and supplies the measured resistance value to the voltage control unit 83 each time.

The voltage control unit 83 controls the high frequency voltage and the pulse voltage according to the resistance value thus measured by the resistance measurement unit 84. For example, the voltage control unit 83 increases the high frequency voltage (increasing the amplitude of the high frequency voltage) as the measured resistance value increases. In order to perform this control, the voltage control unit 83 stores, for example, a first control table in which a range of resistance values and a high frequency voltage are associated with each other.

FIG. 5 shows an example of the first control table. In the example of FIG. 5, the high frequency voltages "Vrf1", "Vrf2" and "Vrf3" (Vrf1 <Vrf2 <Vrf3) are within the range of resistance values "less than R11", "more than R11 and less than R12" and "more than R12". Are associated with each other. When the measurement result is supplied from the resistance measuring unit 84, the voltage control unit 83 applies the high frequency voltage associated with the first control table to the range of the resistance value including the measurement result. As a result, the voltage control unit 83 increases the high frequency voltage as the measured resistance value increases as described above.

The larger the resistance value between the first electrode 21 and the second electrode 22, the smaller the current flowing through the skin when a high frequency voltage is applied, and the less the inside of the skin becomes warm. For example, when the resistance value of the lotion α is less than R11 and the resistance value of the lotion β is R12 or more, the latter is less likely to warm the inside of the skin than the former if the high frequency voltage is the same. Such a difference in the ease of warming the inside of the skin occurs depending on the individual difference of the skin for each user, and also due to the difference in the skin condition of the same user.

Therefore, by performing the above control (voltage control by the voltage control unit 83), it is caused by differences in skin conditions such as individual differences in skin, skin condition, and type of lotion, as compared with the case where this control is not performed. The difference in the magnitude of the current flowing through the skin can be reduced to reduce the temperature difference inside the skin (that is, the difference in the deep thermal effect). In addition, as the skin temperature rises, the resistance value decreases as described above, so that the high frequency voltage also decreases. This also prevents the inside of the skin from being overheated. Further, as described above, since the resistance measuring unit 84 measures the resistance value of the cosmetic water even before the head unit 10 is pressed against the user's skin, the head unit 10 is compared with the case where the above control is not performed. It is possible to reduce the difference in the magnitude of the current flowing through the skin (particularly the difference caused by the difference in the type of lotion) even before it is pressed against the user's skin.

Further, the voltage control unit 83 increases the pulse voltage (increasing the DC voltage included in the pulse voltage) as the measured resistance value increases. In order to perform this control, the voltage control unit 83 stores, for example, a second control table in which the range of the resistance value and the pulse voltage are associated with each other.
FIG. 6 shows an example of the second control table. In the example of FIG. 6, the pulse voltages “Vp1”, “Vp2” and “Vp3” (Vp1 <Vp2 <Vp3) are within the range of resistance values “less than R21”, “R21 or more and less than R22” and “R22 or more”. Are associated with each other.

When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies the pulse voltage associated with the second control table to the range of the resistance value including the measurement result. As a result, the voltage control unit 83 increases the pulse voltage as the measured resistance value increases as described above.

The larger the resistance value between the first electrode 21 and the second electrode 22, the smaller the current flowing through the skin when a pulse voltage is applied, and the less dirt and the like adsorbed on the cotton 70 (the effect of ion derivation is small). Become). Therefore, by performing the above control, the difference in the magnitude of the current flowing through the skin due to the individual difference of the skin, the condition, the type of the lotion, etc. can be reduced, and the dirt adsorbed on the cotton 70 can be prevented. The difference (ie, the difference in the effect of iontophoresis) can be reduced.

Further, the voltage control unit 83 lengthens the first period in which the high frequency voltage is applied as the measured resistance value becomes larger. In order to perform this control, the voltage control unit 83 stores, for example, a third control table in which the range of the resistance value and the first period are associated with each other.
FIG. 7 shows an example of the third control table. In the example of FIG. 7, the first period (Trf1 <Trf2 <Trf3) of "Trf1", "Trf2" and "Trf3" is provided in the range of resistance values "less than R31", "more than R31 and less than R32" and "more than R32". ) Is associated.

When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies a high frequency voltage to the range of the resistance value including the measurement result during the first period associated with the third control table. .. As a result, the voltage control unit 83 lengthens the first period (the period in which the high frequency voltage is applied) as the measured resistance value increases as described above. In this case, in a situation where the inside of the skin is difficult to warm up, the deep thermal effect is enhanced by lengthening the first period.

For example, when the inside of the skin is difficult to warm even when a high frequency voltage is applied at the maximum, the deep thermal effect can be enhanced by lengthening the first period. On the contrary, when the inside of the skin becomes too warm even if the high frequency voltage is applied at the minimum, the deep thermal effect can be suppressed by shortening the first period. Further, even when the first period is changed, the magnitude of the current flowing through the skin due to the individual difference of the skin, the condition of the skin, the type of the lotion, etc. is the same as the case of changing the high frequency voltage. The difference can be reduced to reduce the temperature difference inside the skin (ie, the difference in deep thermal effect).

Further, the voltage control unit 83 lengthens the second period in which the pulse voltage is applied as the measured resistance value becomes larger. In order to perform this control, the voltage control unit 83 stores, for example, a fourth control table in which the range of the resistance value and the second period are associated with each other.
FIG. 8 shows an example of the fourth control table. In the example of FIG. 8, the first period (Tp1 <Tp2 <Tp3) of "Tp1", "Tp2" and "Tp3" is provided in the range of resistance values "less than R41", "more than R41 and less than R42" and "more than R42". ) Is associated.

When the measurement result is supplied from the resistance measurement unit 84, the voltage control unit 83 applies a pulse voltage to the range of the resistance value including the measurement result during the second period associated with the fourth control table. .. As a result, the voltage control unit 83 lengthens the second period (the period in which the pulse voltage is applied) as the measured resistance value increases as described above. In this case, in a situation where dirt or the like is difficult to be adsorbed on the cotton 70, the effect of ion derivation is enhanced by lengthening the second period.

For example, if dirt or the like is not sufficiently adsorbed on the cotton 70 even when a maximum pulse voltage is applied, the effect of ion derivation can be enhanced by lengthening the second period. Further, even when the second period is changed, the magnitude of the current flowing through the skin due to the individual difference of the skin, the condition of the skin, the type of the lotion, etc. is the same as the case of changing the pulse voltage. The difference can be reduced to reduce the difference in dirt and the like adsorbed on the cotton 70 (that is, the difference in the effect of ion derivation).

The first to fourth control tables are not limited to those shown in FIGS. 5 to 8. For example, the range of the resistance value may be two or four or more. Further, each of the above controls may be performed using the relational expression between the resistance value and the high frequency voltage, the pulse voltage, and the first period or the second period. In short, any method may be used as long as the higher the resistance value, the higher the high frequency voltage, the higher the pulse voltage, and the longer the first period or the second period.

The facial device 1 performs a voltage control process for controlling a high frequency voltage and a pulse voltage based on the above configuration.
FIG. 9 shows an example of the operation procedure of the facial device 1 in the voltage control process. This operation procedure is started when the operation of setting the operation mode of the facial device 1 to the cleansing mode and starting the operation is performed. First, the facial device 1 (first power supply unit 81 or second power supply unit 82) starts applying either a high frequency voltage or a pulse voltage (step S10). Which voltage to start from may be determined in advance, or may be the one applied at the end of the previous time.

Next, the facial device 1 (resistance measuring unit 84) measures the resistance value between the first electrode 21 and the second electrode 22 (step S11). Subsequently, the facial device 1 (voltage control unit 83) determines the high frequency voltage to be applied based on the measured resistance value (step S12). Next, the facial device 1 (voltage control unit 83) determines the pulse voltage to be applied based on the measured resistance value (step S13). Subsequently, the facial device 1 (voltage control unit 83) determines the first period and the second period based on the measured resistance value (step S14). The operations of steps S12 to S14 may be performed in different order or in parallel.

Next, the facial device 1 (voltage control unit 83) determines whether or not the measurement interval has elapsed (step S21), and if it determines that the measurement interval has elapsed (YES), returns to step S11 (measurement of resistance value). To operate. If the facial device 1 (voltage control unit 83) determines that the voltage has not elapsed (NO), the application period (the first period when a high frequency voltage is currently applied, and the pulse voltage when a pulse voltage is applied) is applied. It is determined whether or not the second period) has elapsed (step S22).

If the facial equipment 1 (voltage control unit 83) determines that the elapse has not occurred (NO) in step S22, the facial equipment 1 returns to step S21 (determination of the elapse of the measurement interval) to perform an operation, and determines that the elapse (YES). In this case, the type of voltage to be applied is changed (changed to a pulse voltage when a high frequency voltage is currently applied, and changed to a high frequency voltage when a pulse voltage is applied) (step S23). After step S23, the facial device 1 (voltage control unit 83) returns to step S21 (determination of the passage of measurement interval) to perform an operation.

In this embodiment, by controlling the high frequency voltage and the pulse voltage as described above, the difference in the magnitude of the current flowing through the skin due to the individual difference of the skin, the condition of the skin, the type of the lotion, etc. By making it smaller, the difference in deep thermal effect and the effect of ion derivation are reduced. As described above, according to this embodiment, it is possible to reduce the fluctuation of the effect of the cosmetological treatment (deep heat effect and effect of ion derivation) when the situation changes.

Further, in this embodiment, cleansing by ion derivation is performed while warming the inside of the skin by alternately applying a high frequency voltage and a pulse voltage. As described above, the warmer the inside of the skin, the easier it is for the current to flow. Therefore, in this embodiment, by simultaneously performing deep heat, the effect of ion derivation can be enhanced as compared with the case where only the pulse voltage is applied.

Further, in this embodiment, the ring 60, which is a magnetic material, is attracted by the magnet portion 41 provided on the stopper 40 to fix the cotton 70. When the head portion 10 is pressed against the user's skin, the magnetic force generated by the magnet portion 41 passes through the ring 60 and reaches the skin. As a result, a force is applied to the ions in the blood component to activate the movement of the ions and promote blood circulation. In Facial Toning Device 1, the mechanism for fixing the cotton 70 (magnet portion 41 and ring 60) is also used to promote blood circulation, as compared with the case where they are made into another mechanism.
The device can also be miniaturized.

[2] Modifications The above-mentioned examples are merely examples of the implementation of the present invention, and may be modified as follows. In addition, the above-mentioned examples and each modification may be carried out in combination as necessary.

[2-1] Frequency control In the above embodiment, the voltage control unit 83 controls the high frequency voltage, but the frequency of the high frequency voltage may be controlled. In this case, the voltage control unit 83 increases the frequency of the high frequency voltage as the measured resistance value increases. The voltage control unit 83 may perform this control using the control table as described with reference to FIG. 5, or may perform this control using the relational expression between the resistance value and the frequency of the high frequency voltage.

It is known that the higher the frequency of the high frequency voltage, the faster the temperature inside the skin rises. Therefore, even if the frequency of the high frequency voltage is controlled as in this modification, the individual differences in the skin, the condition of the skin, the type of lotion, etc. are the same as in the case of controlling the high frequency voltage in the example of FIG. The difference in the magnitude of the current flowing through the skin due to the difference can be reduced, the temperature difference inside the skin (that is, the difference in the deep thermal effect) can be reduced, and the inside of the skin can be overheated. It can also be prevented.

[2-2] Target of voltage control In the above embodiment, the voltage control unit 83 performs all of the high frequency voltage control, the pulse voltage control, the first period control, and the second period control. At least one or more controls may be performed. Further, the second power supply unit 82 applies the above-mentioned DC voltage instead of the pulse voltage, or applies an AC voltage whose polarity is reversed, and the voltage control unit 83 controls those voltages.

You may. In this case, the negative ion-charged lotion is adsorbed on the skin and easily permeates. In addition, since the skin is warmed to the inside by the deep heat and the cells are activated, the lotion is more easily permeated.

[2-6] Operation Mode In the above embodiment, the facial device 1 is operated in the cleansing mode, but the present invention is not limited to this, and for example, it may be operated in the mode in which the above-mentioned ion introduction is performed while performing deep heat. It may operate in a mode in which only deep heat is performed, a mode in which only dirt is removed, or a mode in which only ion introduction is performed.

[2-7] Direct contact with the skin In the above embodiment, the facial device 1 was used with the bottom surface 31 of the columnar portion 30 covered with the cotton 70, but was used without the cotton 70 covered. You may. In that case, by operating the facial equipment 1 in, for example, the mode in which only the above-mentioned deep heating is performed, the resistance value is measured in a state where the first electrode and the second electrode are in direct contact with the user's skin, and the measured resistance value is measured. Since the high frequency voltage corresponding to the above is applied, it is possible to reduce the fluctuation of the deep thermal effect when the condition such as the skin condition changes, as in the embodiment.

[2-8] First Electrode In the above embodiment, the first electrode has a ring shape with an opening at the center, but may have a disk shape with no opening at the center. Even in that case, since the distance between the first electrode and the second electrode is constant anywhere on the circumference, the heat generation area of the user's skin can be widened and the stimulation by energization can be made uniform.

[2-9] Electrode section In the above embodiment, both the electrode sections are provided with a ring-shaped first electrode and a second electrode, but the present invention is not limited to this. The electrode portion may be provided with, for example, a polygonal and annular first electrode and a second electrode, or may be provided with a rod-shaped first electrode and a second electrode arranged in parallel. Regardless of the shape, it is desirable that the larger the portion where the distance between the first electrode and the second electrode is the shortest, the wider and evenly the high frequency current can be passed.

[2-10] Resistance value In the above embodiment, the resistance measuring unit 84 measures the electrical resistance (resistance) as the resistance value between the first electrode 21 and the second electrode 22, but the resistance is not limited to this, and for example, the first. The reactor between the electrode 21 and the second electrode 22 may be measured as a resistance value. In short, a value indicating the difficulty of current flow between the first electrode 21 and the second electrode 22 may be measured as a resistance value. note that,
A value that represents the ease of current flow, such as conductance, may also be treated as a resistance value because it represents the difficulty of current flow if it is reciprocal.

[2-11] Method for measuring resistance value In the above embodiment, the resistance measuring unit 84 has the first electrode 21 and the second electrode 21 and the second electrode 21 due to the current flowing when a high frequency voltage is applied between the first electrode 21 and the second electrode 22. Although the resistance value between the electrodes 22 is measured, the method for measuring the resistance value is not limited to this. The resistance measuring unit 84 has, for example, the first electrode 21 and the first electrode 21 due to the current flowing when a measuring voltage (for example, a DC voltage) for measuring the resistance value is applied between the first electrode 21 and the second electrode 22. The resistance value between the two electrodes 22 may be measured.

In this case, for example, the resistance measuring unit 84 measures the resistance value by first applying the measuring voltage before the first power supply unit 81 applies the high frequency voltage for deep layer heating, and the height corresponding to the measured resistance value. By controlling the voltage control unit 83 so that the high frequency voltage and the pulse voltage are applied, the difference in the magnitude of the current flowing through the skin can be seen at the start of the beauty treatment as compared with the case where this control is not performed. Can be made smaller from. Further, the resistance measuring unit 84 may provide another pair of electrodes on the bottom surface 31 of the columnar portion 30 to measure the resistance value between them, or a sensor that outputs a value indicating electric resistance on the bottom surface 31.
