It is provided with a skin abnormality detection unit 88. The skin abnormality detection unit 88 receives the light emitting unit 138 that irradiates the test light toward the measured part on the skin surface and the test light reflected by the measured part, and outputs an electrical output value according to the amount of received light. Includes a light receiving unit 139. When the electrical output value of the light receiving unit 139 is equal to or higher than a predetermined electrical reference value, it is determined that the device under test is in a normal state, while when the electrical output value is lower than the electrical reference value, the subject is subject to measurement. It is determined that the measuring unit is in an abnormal state. A predetermined lower limit electrical reference value smaller than the electrical reference value is set. When the electrical output value of the light receiving unit 139 is lower than the lower limit electrical reference value, it is determined that the measured unit is not in an abnormal state.

On the contrary, if the amount of received light is less than the reference amount of light, the measured portion is determined to be in an abnormal state. According to this determination method, the skin condition can be determined by a simple and quantitative standard of the amount of light, so that the configuration of the skin abnormality detection unit 88 can be simplified and the skin condition can always be accurately determined. Further, when the light receiving amount of the light receiving unit 139 is less than a predetermined lower limit reference light amount smaller than the reference light amount, if it is determined that the measured part is not in an abnormal state, a part that does not need to be cared for (for example, a mole) is accurately detected. Therefore, it is possible to prevent the relevant part from being unnecessarily cared for.

The light emitting unit 138 irradiates the area to be measured on the skin surface with inspection light, and the light receiving unit 139 that receives the reflected light at that time outputs an electrical output value such as a current or voltage according to the amount of received light. Then, if the electrical output value of the light receiving unit 139 is equal to or higher than a predetermined electrical reference value, it is determined that the measured unit is in a normal state, and conversely, if the electrical output value is lower than the electrical reference value, the subject is subject to measurement. The measuring unit determines that it is in an abnormal state. According to this determination method, the skin condition can be determined based on a simple and quantitative standard called an electrical output value, so that the configuration of the skin abnormality detection unit 88 can be simplified and the skin condition can always be accurately determined. .. Further, when the electrical output value of the light receiving unit 139 is less than a predetermined lower limit electrical reference value smaller than the electrical reference value, if it is determined that the device under test is not in an abnormal state, a portion that does not need to be cared for (for example, It is possible to accurately detect a mole) and prevent unnecessary care of the relevant part.

By increasing the output of the skin stimulus source 116 in the abnormal part of the skin surface, it is possible to care strongly and intensively for the part and save the user the trouble of switching and operating the output of the skin stimulus source 116. Further, when the notification body 89 is activated on the abnormal portion of the skin surface, the portion can be immediately notified to the user to promote intensive care of the portion.

When it is determined that the part to be measured on the skin surface is not in an abnormal state (for example, it is a mole), if the output of the skin stimulus source 116 is attenuated or stopped, it is more certain that the part is unnecessarily cared for. Can be prevented. Further, when the alarm body 89 is activated in this case, the user is immediately notified that the measured portion is not in an abnormal state (for example, a mole), and care is taken not to give unnecessary stimulation to the portion. Can be prompted.

It can also be attached with a cap 64 and the cotton mat M can be pressed against the skin surface for care. When the cotton mat M is used, the cotton mat M may be impregnated with the beauty liquid, or the cotton mat M may be pressed against the skin surface to which the beauty liquid is directly applied. On the other hand, when the cotton mat M is attached, the cotton mat M is interposed between the skin surface and the measuring unit 143, so that the skin condition cannot be measured by the skin abnormality detecting unit 88. Therefore, if the cotton mat M is switched to the "skin abnormality detection mode" while the cotton mat M is attached, or if the cotton mat M is attached while the "skin abnormality detection mode" is selected, the normal "ion introduction mode" is used. The control to automatically shift to "" is performed, and the details will be described later.

In the "ion derivation mode", "ion introduction mode" and "skin abnormality detection mode", each time the user presses the level changeover switch 105, the pulse current supplied from the current source 175 to the skin stimulator 3 and the grip electrode 10 The strength switches in three stages of "weak", "medium", and "strong". Specifically, in the "ion derivation mode" and "ion introduction mode", a voltage of 6V at "weak", 8V at "medium", and 10V at "strong" is applied to the current source 175. Each is applied. In the "skin abnormality detection mode", the control unit 115 causes the current source 175 based on the drive intensity set by the user with the level changeover switch 105 and the care level determined based on the detection result of the skin abnormality detection unit 88. The voltage applied to is automatically controlled. In this embodiment, the applied voltage is 6 V when the drive intensity is "weak" and the care level is "1", the applied voltage is 8 V when the drive intensity is "medium" and the care level is "1", and the drive intensity is The applied voltage when the care level was "1" at "strong" was set to 10 V, respectively, and the applied voltage was set to increase by 1 V each time the care level increased by one at each drive intensity. The maximum value of the care level is "5", and the applied voltage at this time is 10V when the driving intensity is "weak", 12V when the driving intensity is "medium", and 14V when the driving intensity is "strong". ..

It should be noted that each of the above voltage values is only an example, and it is of course possible to adopt a value other than the above. The same applies to the voltage values and the like listed below. It is only an example that the drive intensity set by the level changeover switch 105 is set to 3 levels and the maximum value of the care level based on the detection result of the skin abnormality detection unit 88 is set to "5", which is different from this. The number of steps and the maximum value may be adopted. Further, in this embodiment, the intensity of the pulse current is changed by changing the voltage applied to the current source 175 to a large or small value and changing the peak value of the pulse current supplied from the current source 175 to a large or small value. Instead of the method, or in combination with this method, a method of changing the duty ratio of the pulse current to a large or small value may be adopted.

As shown in FIGS. 8 and 9, the control unit 115 supplies pulse current from the current source 175 to the skin stimulator 3 and the grip electrode 10 based on the input signals from the switches 103 to 105 and the temperature sensor 167. It controls the drive current supplied to the heater 164 and the vibrator 118, and the display contents on the display units 109, 110, and 117. Further, the control unit 115 has a timer 176 capable of measuring the driving time of the beauty device, and a storage unit 177 that stores a reference voltage V0 (electrical reference value: an electrical output value corresponding to a predetermined reference light amount) described later. Be prepared. The light emitting element 138 is composed of a light emitting diode and is connected to the control unit 115 via a regulator 178, and a resistor (for example, 100Ω) is connected in series to the light emitting element 138. The inspection light emitted from the light emitting element 138 is purple visible light, and its peak wavelength is about 400 nm. The light receiving element 139 is composed of a photodiode and is connected to the control unit 115 via an operational amplifier 179. Specifically, the light receiving element 139 is connected to the inverting input terminal (−) of the operational amplifier 179, and the output terminal of the operational amplifier 179 is connected to the control unit 115.

When a voltage is applied from the control unit 115 to the light emitting element 138 via the regulator 178, the element 138 emits light and the inspection light is emitted toward the user's skin surface. The inspection light is reflected by the user's skin surface and reaches the light receiving element 139. The amount of reflected light at this time changes depending on the skin color of the user, that is, the amount of melanin. Specifically, in the case of a user with dark skin and a large amount of melanin, the amount of reflected light is reduced because the inspection light is absorbed in a relatively large amount on the skin surface. Conversely, for users with white skin and low melanin, the amount of reflected light is large because the amount of test light absorbed is relatively small. Further, even when used by the same user, more inspection light is absorbed and the amount of reflected light is smaller in an abnormal part such as a stain caused by melanin than in a normal part without a stain or the like. The skin abnormality detection unit 88 according to this embodiment detects skin abnormalities such as spots based on the difference in the amount of reflected light. Visible light of purple (380 to 430 nm) is more easily absorbed by melanin than visible light of other colors having a longer wavelength than that, and therefore the difference in the amount of reflected light when irradiating the normal part and the abnormal part is large. , Excellent in detecting skin abnormalities.

The more inspection light that is reflected by the user's skin and reaches the light receiving element 139, the larger the current flows through the light receiving element 139, and the larger voltage is output from the operational amplifier 179 to the control unit 115. This output voltage V can be obtained by multiplying the current I flowing through the light receiving element 139 and the resistor R (for example, 50 MΩ) arranged in the negative feedback circuit. The control unit 115 compares the output voltage V from the operational amplifier 179 with the reference voltage V0 stored in the storage unit 177, and if the output voltage V is the reference voltage V0 or more (V ≧ V0), the inspection part is normal. On the contrary, if the output voltage V is less than the reference voltage V0 (V <V0), the inspection portion is determined to be abnormal. In this embodiment, the amplifier circuit is configured so that the output voltage V increases as the current I increases, but conversely, the amplifier circuit may be configured so that the output voltage V decreases as the current I increases. ..

The reference voltage V0 is a variable that changes according to the skin color of the user. The whiter the color of the normal portion, the higher the voltage is set, and the blacker the color, the lower the voltage. As shown in the flowchart of FIG. 10, when the use of the beauty device in the "skin abnormality detection mode" is started, the control unit 115 sets the reference voltage V0 to, for example, 1.0 V (step S1), and sets the current source 175. The care level of the heater 164 and the vibrator 118 is set to "1" (step S2). Here, the voltage value of 1.0 V is slightly higher than the voltage value (about 0.8 V) output from the operational amplifier 179 when the test light is irradiated from the light emitting element 138 toward the mole. The care level "1" is a care level that generates an electric current stimulus or the like applied to a normal part of the skin surface.

In the next step S3, it is checked whether or not the cotton mat M is attached to the outer surface of the skin stimulator 3. Since a general cotton mat M is white and does not contain melanin at all, if the cotton mat M is irradiated with the test light, the amount of reflected light is larger than that when the skin surface is irradiated with the test light. By using this mechanism, it is possible to determine whether or not the cotton mat M is attached. Specifically, the output voltage V output from the operational amplifier 179 to the control unit 115 is set to a predetermined maximum voltage VM (upper limit electrical reference value: electrical output value corresponding to a predetermined upper limit reference light amount) (for example, 2.8 V). ), If the output voltage V exceeds the maximum voltage VM (YES in step S3), it is determined that the cotton mat M is attached to the outer surface of the skin stimulator 3, and the "skin abnormality detection mode" is terminated. Then (step S4), the process shifts to the normal “ion introduction mode”. On the other hand, if the output voltage V is equal to or less than the maximum voltage VM (NO in step S3), it is determined that it is not the cotton mat M but the user's skin that faces the measuring unit 143, and the next step S5 Proceed to.

In the next step S5, the output voltage V is compared with the reference voltage V0. In the initial state where the reference voltage V0 is set to 1.0V, in most cases, the output voltage V exceeds the reference voltage V0 (V> V0), and the output voltage V is set as the new reference voltage V0 in the next step S6. Set. In the next step S7, if the care level is set to other than "1", the care level is set to "1" and the process returns to step S3. When the user moves the beauty device along the skin surface, the reference voltage V0 is repeatedly updated in step S6, and the reference voltage V0 corresponding to the user's skin color is set. That is, the output voltage V in the fairest part of the user's skin, that is, the normal part without stains, is set as the final reference voltage V0. The reference voltage V0 stored in the storage unit 177 is reset to an initial value (for example, 1.0 V) each time the power of the beauty device is turned off.

In step S5, if the output voltage V and the reference voltage V0 are equal (V = V0), the process proceeds to step S7 without going through step S6, and if the care level is set to other than "1", the care level is set to "1". Set to "1" and return to step S3. On the other hand, if the output voltage V is lower than the reference voltage V0 (V <V0) in step S5, the process proceeds to step S8, and the output voltage V is set to a predetermined minimum voltage Vm (lower limit electrical reference value: predetermined lower limit reference light amount). Compare with the corresponding electrical output value). The minimum voltage Vm is a constant set to 0.8 V, which is the same as the output voltage value when the mole is irradiated with the inspection light, and is stored in the storage unit 177 in advance. When the output voltage V is lower than the minimum voltage Vm (YES in step S8), it is determined that the skin stimulator 3 is facing a mole that does not need to be cared for, so as not to give unnecessary stimulation to the mole. The care level of each skin stimulus source 116 is set to "0" or more and "1" or less (step S9), the output of each skin stimulus source 116 is stopped or attenuated, and the process returns to step S3. The care level "0" is a care level at which the output of the skin stimulus source 116 is stopped and no irritation is generated from the skin stimulus source 116. The care levels of the current source 175, the heater 164, and the vibrator 118 here may be individually set between "0" and "1".

If the output voltage V is equal to or greater than the minimum voltage Vm in step S8 (NO in step S8), the process proceeds to step S10, and the difference between the reference voltage V0 and the output voltage V is compared with the predetermined constant C. The constant C is a positive number stored in advance in the storage unit 177 (C> 0). If the difference between the reference voltage V0 and the output voltage V is equal to or less than the constant C (YES in step S10), the care level is set to "2", which is stronger than "1" (step S11), and the process returns to step S3. On the contrary, when this difference exceeds the constant C (NO in step S10), the process proceeds to step S12.

In step S12, the difference between the reference voltage V0 and the output voltage V is compared with a value twice the constant C. If this difference is not more than twice the constant C (YES in step S12), the care level is set to "3", which is stronger than "2" (step S13), and the process returns to step S3. On the contrary, when this difference exceeds twice the constant C (NO in step S12), the process proceeds to step S14, and the difference between the reference voltage V0 and the output voltage V is compared with the value three times the constant C. If this difference is 3 times or less of the constant C (YES in step S14), the care level is set to "4", which is stronger than "3" (step S15), and the process returns to step S3. On the contrary, when this difference exceeds 3 times the constant C (NO in step S14), the care level is set to “5” which is stronger than “4” (step S16), and the process returns to step S3.

Summarizing steps S10 to S16, when the difference between the reference voltage V0 and the output voltage V is equal to or less than the constant C (0 <V0-V≤C), the care level is set to "2", and this difference exceeds the constant C. The care level is set to "3" when it does not exceed twice (C <V0-V ≦ 2C). Further, when the difference between the reference voltage V0 and the output voltage V exceeds twice the constant C and does not exceed three times (2C <V0-V ≦ 3C), the care level is set to "4", and this difference is set to the constant C. The care level is set to "5" when it exceeds 3 times (3C <V0-V). Instead of the constant C used in this embodiment, for example, a variable that changes according to the reference voltage V0 can be used.

As described above, in step S9, when a mole is detected (YES in step S8), the output of each skin stimulus source 116 is stopped or attenuated. In the present invention, the attenuation of the output (care level) of the skin stimulus source 116 is a concept that includes not only reducing the output (care level) to the minimum output excluding the stopped state but also maintaining the output (care level) at the minimum output. That is, in step S9, when the care level of the skin stimulus source 116 is set to "1", if the care level immediately before that is "2" or higher, the care level is lowered to "1" in step S9. On the other hand, if the care level immediately before that is already "1", the care level is maintained at "1" in step S9, but in the present invention, these are included and referred to as attenuation.

When the user grasps the grip portion 101 with his / her hand and touches the grip electrode 10 and brings the skin stimulator 3 into contact with the skin surface such as the face, the internal circuit of the beauty device connecting the skin stimulator 3 and the grip electrode 10 and the user. An electrically closed loop consisting of the human body is formed. The control unit 115 determines whether or not the stimulation surface 3a is in contact with the skin surface based on the presence or absence of the formation of the closed loop. That is, the skin stimulator 3 according to the present embodiment functions as a skin detection sensor that detects that the stimulating surface 3a is in contact with the skin surface. The control unit 115 supplies a pulse current for skin stimulation from the current source 175 to the skin stimulator 3 and the grip electrode 10 and supplies a drive current to the vibrator 118 only in the state of detecting this closed loop. Further, the control unit 115 supplies electric power to the light emitting element 138 to drive the skin abnormality detection unit 88 only in the state of detecting this closed loop, and also supplies electric power to the head display unit 117 to emit light. Let me. When the electrically closed loop is not formed, that is, when the stimulation surface 3a is separated from the skin surface, the pulse current for skin stimulation and the drive current of the vibrator 118 are supplied, and the skin abnormality detection unit 88 is driven. When the light emitting display of the head display unit 117 is stopped, the power consumption of the beauty device can be suppressed.

The skin detection sensor may be composed of an optical sensor or the like that is separate from the skin stimulator 3. When the optical sensor is arranged on the stimulating surface 3a of the skin stimulating body 3, the stimulating surface 3a comes into contact with the skin surface, so that the optical sensor cannot receive room light. Taking this opportunity, a signal is transmitted from the optical sensor to the control unit 115, and the control unit 115 that receives this signal determines that the stimulation surface 3a has come into contact with the skin surface, and supplies a pulse current from the current source 175. , Start driving the skin abnormality detection unit 88 and the like.

Next, a case where the beauty device according to this embodiment is used in the "skin abnormality detection mode" will be described. As described above, the "skin abnormality detection mode" is a drive mode in which ions are introduced while driving the skin abnormality detection unit 88, and the control unit 115 not only drives the skin abnormality detection unit 88 but also the skin stimulator 3 A pulse current for skin stimulation is supplied to the grip electrode 10, and the heater 164 and the vibrator 118 are further driven. That is, while measuring the user's skin condition, current stimulation, thermal stimulation, and vibration stimulation are applied to the skin surface. When the skin abnormality detection unit 88 detects an abnormal part such as a spot, the current stimulation or the like is automatically enhanced in the abnormal part to strongly and intensively care for the abnormal part. That is, in the normal part of the skin surface, the care level of the skin stimulation source 116 (current source 175, heater 164, vibrator 118) is set to "1", and in the abnormal part, "2" to "2" depending on the degree of abnormality. Set to "5". In the mole portion, the care level of each skin stimulus source 116 is set to "0" to "1".

In the timing chart of FIG. 11, when the user turns on the power switch 103 and operates the mode selection switch 104 to select the “skin abnormality detection mode” (time point t0), the control unit 115 displays the mode display unit 109. The current source 175 is controlled so as to switch to start timing by the timer 176 and to start supplying a weak pulse current for skin detection to the skin stimulator 3 and the grip electrode 10. At the same time, the control unit 115 lights the light emitting element 138 of the skin abnormality detection unit 88 for a moment (for example, 0.2 seconds). When the light emitting element 138 is temporarily turned on when the "skin abnormality detection mode" is selected, the drive mode is switched to the "skin abnormality detection mode" in combination with the display switching of the mode display unit 109. It can be clearly recognized by the user. The light emitting element 138 is temporarily turned on and then turned off, and is turned on again when the skin detection state in which an electrically closed loop is formed (time point t1 described later) is reached. The user cannot confirm that the light emitting element 138 is lit in the skin detection state, that is, in the state where the skin stimulator 3 is in contact with the skin surface. Temporarily turning on the light emitting element 138 when the "skin abnormality detection mode" is selected also means having the user confirm the operation of the light emitting element 138. That is, the user can know that the light emitting element 138 is in the normal state and has not failed, and the state of light emission such as the light emitting color in the lighting state through the temporary lighting of the light emitting element 138. Approximately 5 seconds after the power is turned on, the control unit 115 starts energizing the heater 164 to preheat the skin stimulator 3. The care level of the heater 164 at this time is "1". The control unit 115 controls the heater 164 on and off so as to maintain the surface temperature of the stimulating surface 3a of the skin stimulator 3 at about 40 ° C. based on the input signal from the temperature sensor 167.

In the beauty device according to this embodiment, the drive mode is reset to the "ion derivation mode" every time the power is turned off, so that the time when the "skin abnormality detection mode" is selected with the mode selection switch 104 after the power is turned on is , At the time point t0 in the timing chart of FIG. 11, in the beauty equipment in which the drive mode is memorized even when the power is turned off, if the power is turned off with the "skin abnormality detection mode" selected, the following Since the "skin abnormality detection mode" is selected from the beginning when the power is turned on, the time when the power switch 103 is turned on is the time t0 in FIG. Further, even in the beauty appliance having only the "skin abnormality detection mode" as the drive mode, the time point when the power switch 103 is turned on is the time point t0 in FIG.

When the user grips the grip portion 101 and brings the skin stimulator 3 into contact with the skin surface, the electrically closed loop described above is formed. The control unit 115 that detects this closed loop supplies a pulse current for skin stimulation from the current source 175 to the skin stimulator 3 and the grip electrode 10, supplies a drive current to the vibrator 118, and emits light from the head display unit 117. The display and the irradiation of the inspection light from the light emitting element 138 to the skin surface are started (time point t1). At this time, the care level of the current source 175 and the vibrator 118 is "1", and the care level of the heater 164 is also maintained at "1". The head display unit 117 indicates that the care level of the skin stimulus source 116 is "1", for example, with blue light.

When the care level is "1", the pulse current for skin stimulation supplied to the skin stimulator 3 is weak, so that the user cannot easily recognize that the current is being supplied. Therefore, in this embodiment, when the pulse current of the care level "1" is supplied, the vibrator 118 and the heater 164 are driven at the same time, and the head display unit 117 is made to emit light. Since it is easy for the user to recognize that the vibrator 118, the heater 164, and the head display unit 117 are energized regardless of the care level, the user can recognize that the energization is applied to the care level "1". It can be recognized that the pulse current of is supplied. That is, the vibrator 118, the heater 164, and the head display unit 117 function as an energizing display body that indicates that the pulse current for skin stimulation is supplied to the skin stimulating body 3.

Between time points t1 and time point t4, the reference voltage V0 is updated a plurality of times according to the procedure described with reference to FIG. At the time point t2, the output voltage V on the light receiving side fell below the reference voltage V0, so that the care level of the skin stimulus source 116 temporarily rose to "2", and at the next time point t3, the output voltage V increased. By exceeding the reference voltage V0, the reference voltage V0 is updated and the care level returns to "1". After the reference voltage V0 is set to 2.4V at the time point t4, the reference voltage V0 has not been updated. Therefore, at the time point t4, the skin abnormality detection unit 88 faces the fairest part of the user's skin. You can see that it was done. Of course, the voltage value of 2.4V is just an example, and if another user with a different skin color uses a beauty device, the reference voltage V0 will change. Further, even when one user continues to use the beauty device, the reference voltage V0 may change accordingly if the part to be cared for changes. Further, even if one user continues to use the beauty device for the care of one place, the reference voltage V0 may fluctuate due to the influence of the daily living environment and the like.

From the time point t5 to just before the time point t6, the output voltage V fluctuates between the reference voltage V0 (2.4V) and the minimum voltage Vm (0.8V), and the care level of the skin stimulus source 116 is "2" to "". It fluctuates between "5". During this time, the head display unit 117 indicates that the care level is "2" to "5" with lights of different colors. For example, the care level "2" can display green light, the care level "3" can display yellow light, the care level "4" can display orange light, and the care level "5" can display red light. When a light other than blue indicating the care level "1" is displayed on the head display unit 117, it is possible to notify the user that the skin abnormality detection unit 88 has detected the skin abnormality. That is, the head display unit 117 according to this embodiment constitutes a notification body 89 that notifies the user that the skin abnormality detection unit 88 has detected the skin abnormality. The user can also recognize that the skin abnormality detection unit 88 has detected the skin abnormality by increasing the care level of the vibrator 118, that is, by increasing the vibration and sound caused by the vibrator 118. Further, the user can recognize that the skin abnormality detecting unit 88 has detected the skin abnormality by increasing the care level of the heater 164, that is, increasing the surface temperature of the stimulating surface 3a. That is, the vibrator 118 and the heater 164 not only form the skin stimulus source 116, but also form the notification body 89 together with the head display unit 117.

As described above, the vibrator 118, the heater 164, and the head display unit 117 function as an energization display body for the pulse current for skin stimulation. That is, the vibrator 118 and the heater 164 have three roles of the skin stimulus source 116, the notification body 89, and the energization display, respectively, and the head display unit 117 has two roles of the notification body 89 and the energization display. I have. Contrary to this embodiment, the vibrator 118, the heater 164, and the head display unit 117 are stopped when the pulse current of the care level "1" is supplied, and the vibrator 118 and the like are supplied when the pulse current of the care level "2" or higher is supplied. Although the vibrator 118 and the like cannot be used as the energizing display body in the form of driving the vibrator, the role as the skin stimulating source 116 and the notification body 89 remains.

In this embodiment, the color of the head display unit 117 changes as the care level changes, but instead, the head display unit 117 is made a single color and its illuminance is gradually increased as the care level increases. It may be higher. In this case, the color of the head display unit 117 can be arbitrarily selected from blue, red, green, and the like. Further, a sounding means such as a buzzer or a synthetic voice can be adopted in place of or in combination with the light emitting means such as the head display unit 117. In this case, the user is informed that the care level has changed through hearing by changing the timbre of the sounding means as the care level changes or by gradually increasing the volume of the sounding means as the care level rises. I can inform you.

At time point t6, the output voltage V on the light receiving side shows 0.8 V, which is equal to the minimum voltage Vm. In this case, the control unit 115 determines that the skin abnormality detection unit 88 is facing the mole, sets the care level of the current source 175 and the vibrator 118 to "0" or more and "1" or less, and also sets the heater 164. Set the care level of to "1". Further, the control unit 115 blinks the head display unit 117 in an arbitrary color. The user can recognize that the skin abnormality detection unit 88 is facing the mole based on the fact that the head display unit 117 is switched to the blinking display and the vibration and sound of the vibrator 118 are weakened. The head display unit 117 at the time of mole determination can be displayed in a discolored state in which the color changes every few seconds, or can be turned off. Further, in this embodiment, each skin stimulus source 116 (current source 175, vibrator 118, heater 164) was driven at the time of mole determination, but instead, at least one of the skin stimulus sources 116 at the time of mole determination was driven. The care level may be set to "0" to stop the stimulation applied to the skin surface from the skin stimulation source 116.

At the time point t7, the electrically closed loop disappears when the user separates the skin stimulator 3 from the skin surface, and the control unit 115 that cannot detect this closed loop stops the irradiation of the inspection light from the light emitting element 138. At the same time, the pulse current supplied from the current source 175 to the skin stimulator 3 and the grip electrode 10 is switched from the one for skin stimulation to the weak one for skin detection. Further, the control unit 115 sets the care level of the vibrator 118 to "0" and sets the care level of the heater 164 to "1" to put it in a preheated state, and further turns off the head display unit 117. At the next time point t8, the control unit 115 re-detects the electrically closed loop, so that the irradiation of the inspection light from the light emitting element 138 is restarted. When 3 minutes have passed since the timer 176 started timing, the control unit 115 turns off the skin stimulus source 116, cuts off the power supply to the light emitting element 138 and the head display unit 117, and stops the beauty equipment. (Time point t9). That is, the power of the beauty equipment is turned off. If the power switch 103 is operated by the user before 3 minutes have passed from the start of timekeeping, the control unit 115 stops the beauty device at that time as in the case of 3 minutes, and powers the beauty device. Cut off.

As shown in FIG. 12, regarding the output voltage V based on the light receiving amount of the light receiving element 139, three determination regions with the minimum voltage Vm (0.8V) and the maximum voltage VM (2.8V) as boundaries are assumed. Can be done. When the output voltage V is included in the "mole determination region" having a minimum voltage Vm or less, the control unit 115 determines that the skin stimulator 3 faces the mole. When the output voltage V is included in the "sheet body determination region" exceeding the maximum voltage VM, the control unit 115 determines that the cotton mat M is attached to the outer surface of the skin stimulator 3. The upper limit of 3.0 V in the "sheet body determination region" is substantially equal to the voltage value output from the operational amplifier 179 when 100% of the inspection light emitted from the light emitting element 138 is reflected. Further, when the output voltage V is included in the "skin condition determination region" of the minimum voltage Vm or more and the maximum voltage VM or less, the control unit 115 compares the output voltage V with the reference voltage V0, and the skin condition is normal or abnormal. Is determined. The initial value of the reference voltage V0 is set to a low value within the range of the "skin condition determination region", preferably close to the minimum voltage Vm, and fluctuates (rises) according to the user's skin color within the range of the same region. To do. The reference voltage V0 does not fall below the minimum voltage Vm or exceed the maximum voltage VM.

On the other hand, the timing chart of FIG. 13 shows a case where the “skin abnormality detection mode” is selected with the white cotton mat M attached to the outer surface of the skin stimulator 3. The period from the time point t0 to immediately before the time point t1 is the same as in FIG. 11 described above, but at the time point t1 when the irradiation of the inspection light is started, since the cotton mat M is attached, the output on the light receiving side is output. The voltage V shows 3.0 V, which exceeds the maximum voltage VM. At the next time point t10, the control unit 115 that has received the high output voltage V determines that the cotton mat M is attached, stops the irradiation of the inspection light, ends the "skin abnormality detection mode", and is normal. We are shifting to the "ion introduction mode". At the time of this transition, the head display unit 117 switches to a red blinking display. Based on this, the user can recognize that the skin abnormality detection unit 88 is not functioning because the cotton mat M is attached. After the time point t10, the output of each skin stimulus source 116 (current source 175, heater 164, vibrator 118) is maintained at a constant value corresponding to the care level "1" in the "skin abnormality detection mode". Since the time points t11 to t13 in FIG. 13 are the same as the time points t7 to t9 in FIG. 11, the description thereof will be omitted. The time interval between the time point t1 and the time point t10 is extremely short, but in FIG. 13, for convenience of illustration, this interval is set longer than the actual time.

In this embodiment, the head display unit 117 is switched to a red blinking display in order to notify the user that the function of the skin abnormality detection unit 88 has stopped at the time point t10. Instead, for example, the head display unit 117 is used. It may be lit or blinked in a color different from that when the skin abnormality detection unit 88 is driven, or it may be a discolored display in which the color changes at regular intervals. Further, instead of changing the display mode of the head display unit 117, or in conjunction with the change of the display mode, control may be performed to change the operating state of the voice means such as a buzzer. This voice control may switch the voice means from a stopped state to an operating state, or may change the volume or timbre of the voice means. It is also possible to use a synthetic voice that informs the user of the stoppage of the function of the skin abnormality detection unit 88 in words.

(Example 2) FIG. 14 shows Example 2 of the beauty device according to the present invention, which is different from the previous Example 1 in that a pair of upper and lower optical path forming bodies 140 and 141 are provided.

In the stimulating surface 3a of the skin stimulating body 3, a measuring unit 143 configured on the front surface of the lens 142 of the skin abnormality detecting unit 88 is arranged. According to this beauty device, when the stimulating surface 3a is brought into contact with the skin surface, the measuring unit 143 faces the skin surface at the same time, so that the skin stimulus is performed while checking the condition of the skin surface with the skin abnormality detecting unit 88. It is possible to take care of the skin surface by the body 3. Therefore, the time required for detecting and caring for skin abnormalities can be significantly shortened as compared with the conventional beauty method in which the skin health sensor and the beauty device are used separately. Moreover, the position of the abnormal part of the skin surface can be precisely identified in real time, and the identified abnormal part can be accurately and intensively cared for.
