In particular, the contact surface 111 comprises a plurality of electrodes 112 arranged such that adjacent electrodes 112 have different polarities, and through these electrodes 112, electrical stimulation such as high frequency is applied to the user's skin. Also, it detects whether the contact surface 111 is in contact with the skin via the electrode 112 .

Further, the contact surface 111 has regions 114 arranged such that there are a plurality of places where the shortest distance between the electrodes 112 is a predetermined length in the plurality of electrodes 112 facing each other. Further description will be made below using specific examples.

In the example of the contact surface 111a, five electrodes 112 with different widths and lengths are arranged. Here, a rectangular region 114a is provided by arranging the straight portion 113a of the electrode 112a and the straight portion 113b of the electrode 112b such that the shortest distance is a predetermined length.

The number of electrodes 112 arranged on the contact surface 111 may be 10 or more (contact surface 111b), or the areas of the electrodes 112 may be substantially the same (contact surface 111c and contact surface 111b). 111d).

Moreover, even if the electrodes 112 are curved, it is preferable that the electrodes 112 are arranged parallel to each other. 5 and 6 are diagrams showing an example of the contact surface 111 on which the curved electrodes 112 are arranged.

Also, like the contact surface 111h, there may be a portion other than the region 114 where the shortest distance between the electrodes is not the predetermined length.

7 and 8 are diagrams showing an example of the contact surface 111 on which the electrode 112 without the straight portion 113 is arranged. As shown in FIG. 7, even if the arranged electrodes 112e and 112f do not have the straight portion 113, they should be arranged so that there are a plurality of places where the shortest distance between the electrodes is a predetermined length. is preferred. The contact surface 111j shown in FIG. 7 has a curved region 114c, and the width of the region 114c is constant.

2. Functional Configuration This section describes the functional configuration of the first embodiment. FIG. 10 is a functional block diagram showing functions of the beauty device 1. As shown in FIG. As described above, information processing by software (stored in the storage unit 14 ) is specifically realized by hardware (control unit 15 ), and can be executed as each functional unit included in the control unit 15 .

Specifically, the beauty device 1 (the control unit 15) includes a detection unit 151, an adjustment unit 152, a determination unit 153, a specification unit 154, and an output unit 155 as functional units.

3. Details of Information Processing In Section 3, an information processing method executed by the beauty device 1 will be described with reference to activity diagrams. FIG. 11 is an activity diagram showing an example of information processing by the beauty device 1. As shown in FIG. As shown below, the information processing method comprises the following steps. Note that the order of the following processes can be changed as appropriate, and a plurality of processes may be executed simultaneously, or not all of them need to be executed.

When using the beauty device 1, the user applies lotion, milky lotion, or the like, activates the beauty device 1, and selects an arbitrary treatment mode. Hereinafter, it is assumed that the cosmetic device 1 having two electrodes 112 arranged on the contact surface 111 is used (see FIG. 1).

First, as a preparation before treatment, an output reference is set when the entire surface of the electrode 112 is brought into contact with the skin. First, the user brings the beauty device 1 into contact with the skin so that the entire electrode 112 touches the skin. When the detection unit 151 detects that the entire surface of the electrode 112 is in contact with the treatment target, the output unit 155 outputs power of a preset voltage (A101).

The determination unit 153 determines the current value output at this time as an output reference when the entire surface is in contact with the treatment target (A102). As a result, it is possible to record the skin condition when the beauty device 1 is in use, as the electric resistance changes according to the user's skin type and cosmetics applied to the skin. Note that the output criteria may be set in advance.

Once the output criteria are determined, the user can start treatment using the beauty device 1 . When the detection unit 151 detects that the beauty device 1 touches the user's skin, the output unit 155 outputs power to apply a predetermined beauty effect (A103).

At A<b>104 , the detection unit 151 detects the contact rate of the treatment target with respect to the entire surface of the electrode 112 . Specifically, when the current value output at this time is lower than the reference value determined in A102, the detection unit 151 newly calculates the ratio of the current value to the output reference in A103, the surface of the electrode 112. It is detected as the ratio of contact with the treatment target to the whole. For example, an output reference power is applied, and the reference current value that actually flows is set to "1". At this time, when the current value actually output at A103 is 0.5, 50% of the entire surface of the electrode 112 arranged on the contact surface 111 is in contact with the treatment target. In this way, the detection unit 151 detects the contact rate of the treatment target with respect to the entire surface of the electrode 112 based on the comparison between the determined output reference and the current value of the output power.

The adjusting unit 152 adjusts the power so that the amount of current decreases as the contact ratio decreases, and the output unit 155 continues to output the adjusted power for a predetermined time (A105).

For example, the adjustment unit 152 adjusts the output power as follows according to the ratio of the contact area.
(1) When the contact ratio is 90% or more, output power of 100% of the output standard.
(2) When the contact ratio is 60% or more and less than 90%, the power of 85% or more and less than 95% of the output standard is output. Preferably, the power output is 90% of the output standard.
(3) When the contact ratio is 40% or more and less than 60%, the power of 75% or more and less than 85% of the output standard is output. Preferably, the power output is 80% of the output standard.
(4) When the contact ratio is 20% or more and less than 40%, the power of 55% or more and less than 75% of the output standard is output. Preferably, the power output is 60% of the output standard.
(5) If the contact ratio is 19% or less, output power equal to or greater than 35% and less than 55% of the output standard. Preferably, the power output is 40% of the output standard.

Note that it is preferable to return to A103 and repeat the series of processes after a predetermined period of time has elapsed. In addition, when the contact surface 111 touches the skin again and the treatment is restarted after the current has become 0 because the user completely separates the electrode 112 from the skin in order to perform treatment on another site, A103 back to Further, when the treatment mode is switched, it is preferable to return to A101, and when the user stops the activation of the beauty device 1, this information processing ends.

In this way, the area where the skin is in contact with the electrode 112 is detected, and the power is adjusted to the output according to the contact ratio (contact area) with the skin. As a result, when the area of contact with the contact surface 111 is small, such as when a part with many irregularities such as the nose and chin is to be treated, current flows intensively in the contact area, but the amount of current is reduced. It is possible to prevent the temperature from rising rapidly.

4. Modifications In Section 4, a process in which three or more electrodes 112 are arranged on the contact surface 111 to have a plurality of regions 114 will be described.

4.1 Modification 1
When a plurality of regions 114 are provided, electric power is output between the electrodes, and the current value actually flowing through the skin is taken as the reference current value “1”. Then, in A104, the contact ratio of each region 114 with respect to the entire surface is detected based on the comparison between the actual current value and the reference current value, and then the contact ratio of each region 114 is detected. That is, the detection unit 151 compares the output reference set for each region 114 with the current value of the power output for each region 114, and detects the ratio of contact with the treatment target with respect to the entire surface of each region 114. do. After that, the power is adjusted to the output according to the contact ratio.

The determination unit 153 determines the output reference for each region 114 by periodically outputting power to different regions 114 (A102). For example, as shown in FIG. 3, when there are four regions 114 (regions 114a, 114b, 114c, and 114d), the output unit 155 outputs a state in which all the regions 114 are in contact with the treatment target. , and periodically outputs power to each region 114 . For example, the determination unit 153 applies a predetermined electric power to the skin, sets the current value output in 0.01 second elapsed time after the start of output as the reference current value actually flowing through the skin, Determines the output criteria for In other words, this reference current value becomes the output reference for each region 114 .

In A103, when the electrode 112 touches the skin again, power is periodically output to each region 114, similarly to when the output reference was determined. , the amount of current for each region 114 is specified. For example, when the reference current value (output reference) of each region 114 is set to "1", the output unit 155 outputs a current value of "1" to each region 114 for 0.01 seconds.

In this case, 0.01 second is output for each of the four areas 114 . For example, assuming that the area 114a, the area 114b, the area 114c, and the area 114e are output in order, one cycle takes 0.04 seconds as follows.
(1) The area 114a is to be output from the start of output to 0.01 seconds.
(2) The output target from 0.01 seconds to 0.02 seconds is the area 114b.
(3) The output target from 0.02 seconds to 0.03 seconds is the area 114c.
(4) The output target from 0.03 seconds to 0.04 seconds is the area 114e.

In A103, the current value output from the start of output until 0.01 seconds has passed is "1", and the current value output from 0.01 seconds after the start of output to 0.02 seconds is " 0.5", it is specified that the entire surface of the area 114b that is the output target from 0.01 seconds to 0.02 seconds is not in contact with the treatment target.

On the other hand, the detection unit 151 determines that the current value output from 0.01 seconds to 0.02 seconds is a current value that is 50% of the reference current value “1” that is the output reference. Therefore, it is determined that the contact ratio of this region 114 to the entire surface is 50%. After that, the adjustment unit 152 adjusts the power so that the amount of current that is output from 0.05 seconds after the cycle starts anew to 0.06 seconds becomes 80% of the output reference ( A104). Similarly, in the third cycle, the amount of current output from 0.09 seconds to 0.1 seconds is also adjusted. In this way, the detection unit 151 detects the contact ratio for each region 114 based on the comparison between the output reference for each region 114 and the current value for each specified region 114, and the adjustment unit 152 detects the contact ratio for each region 114. every time, the power is adjusted to the output corresponding to the contact ratio (A105). In addition, by periodically repeating the output in this way, the contact ratio can be detected for each area 114 even if the area 114 to be output cannot be individually recognized for each time unit during the period. If the process at A105 has been executed for a predetermined time, the process may be returned to A103 and repeated, and if the cycle has been repeated a predetermined number of times, the process may return to A103.

4.2 Modification 2
When the areas 114 to be output can be individually identified in advance, the determining unit 153 determines the output reference for each area 114 by outputting the power for each area 114, and the detecting unit 151 outputs power for each area 114. A contact rate can be detected. In this case, the detection unit 151 can detect the contact ratio for each region 114 even if power is not periodically output.

4.3 Modification 3
In the above example, the electrodes 112 function both to detect contact with the skin and to apply electrical stimulation. Contact availability may be detected via a light receiving element. The light receiving elements are arranged at regular intervals of 1 mm or more and 4 mm or less on the contact surface 111 on which the linear electrodes 112 (see FIGS. 3 and 4) are arranged, for example. Specifically, they are 1, 2, 3, and 4 mm, and may be within a range between any two of the numerical values exemplified here. In this case, the detection unit 151 determines that the entire surface of the electrode 112 is out of contact when the amount of light received by the light receiving element is higher than the threshold. For example, assume that three light receiving elements are arranged between the electrodes. At this time, when the amount of light received by two of the three light receiving elements is higher than the threshold value, the detection unit 151 determines that the light receiving elements are out of contact, and the area in contact with the electrode 112 is one-third. Determine that there is. Thus, in A104, the detection unit 151 determines the ratio of the contact area by the ratio of the number of light receiving elements determined to be non-contact to the total number of light receiving elements arranged on the surface of the contact surface 111. To detect.

Furthermore, light emitting elements may be arranged at predetermined intervals together with the light receiving elements. In this case, when the amount of light received by the light-receiving element from the light-emitting element is lower than the threshold, the detection unit 151 determines that the amount of light reflected from the light-emitting element is small and the light-receiving element is not in contact with the skin. In this manner, the detection unit 151 may determine whether or not the electrode 112 is in contact by measuring the reflection from the light emitting element.

To summarize the above, as explained in Section 1, the electrodes 112 are arranged so that the skin can be stimulated evenly over a wide area. If a part of the skin is not in contact with the skin, the electric current may flow intensively in the contact part, resulting in excessive heat. By adjusting the output according to the needs, it can be used more safely by general users with peace of mind.
