  The apparatus main body 10 includes a rechargeable secondary battery, a power cable for inputting the power of the secondary battery, the power of the commercial power source, and the like to the light irradiation unit 20, and the light of the light irradiation unit 20 A signal transmission / reception cable for controlling the irradiation timing can also be provided.

The apparatus main body 10 has rounded corners as a whole so that the user can easily hold it with one hand. The apparatus main body 10 has a gentle "<" shape as a whole (generally a substantially arc shape).
The light irradiation unit 20 is detachably attached to the distal end portion 10a. Although not shown here, the distal end portion 10 a includes a holding mechanism for holding the light irradiation unit 20.

  The holding mechanism is not particularly limited as long as the light irradiation unit 20 can be prevented from easily falling off from the distal end portion 10a. The holding mechanism is, for example, a magnet. In this case, it is desirable to form at least a part of the light irradiation unit 20 with a metal. The tip portion 10a and the light irradiation unit 20 may include magnets having opposite polarities.

The terminal portion 110 is exposed at the rear end portion 10b.
The partition portion 10 c is located at the tip portion 10 a inside the apparatus main body 10. The partition part 10c faces the light irradiation part 20 with which it was mounted | worn. Although not shown here, the partition 10c is provided with a contact terminal that is electrically connected to the light irradiator 20 and the like. The above holding mechanism may be provided in the partition portion 10c.

The ventilation hole 10d penetrates from the front surface of the apparatus main body 10 to the back surface. The ventilation hole 10d is an exhaust port.
Ventilation hole 10e penetrates from the surface of partition part 10c to the back. In this embodiment, the vent hole 10d is an intake port.

  The terminal part 110 is provided in order to connect the light irradiation type beauty apparatus 1 with a commercial power source. The light irradiation part 20 can irradiate light with a commercial power supply, or can charge a secondary battery. The terminal part 110 is connected to the control board 130 by a cable (not shown).

  The operation unit 112 includes, for example, a switch and a display. The operation unit 112 is provided on the surface of the apparatus main body 10. The operation unit 112 is located on the opposite side of the ventilation hole 10d. The switches are, for example, a main switch, a light irradiation switch, and an operation mode changeover switch for the user to turn on and off the main power supply of the light irradiation type beauty apparatus 1.

When the user operates the light irradiation switch, the user can manually irradiate light from the light irradiation unit 20 at a desired timing.
By operating the operation mode switch, the intensity of light emitted by the light irradiation unit 20 can be changed, or the function of the light irradiation switch can be prevented from being used.

  The display includes, for example, a light emitting diode (LED) and a liquid crystal screen. The display allows the user to know the current mode of the light-irradiating beauty device 1.

  The cooling fan 114 is, for example, a sirocco fan or a turbo fan. The cooling fan 114 takes in outside air into the apparatus main body 10 through the light irradiation unit 20 and the ventilation hole 10e attached to the tip 10a (see “Air1” in the figure). The taken-in air inside the apparatus main body 10 exits from the ventilation hole 10d (see “Air2” in the figure).

(About the light irradiation unit 20)
As shown in FIGS. 2 and 3, the light irradiation unit 20 includes a housing 210 (a main body having a first surface in contact with the skin surface), a xenon tube 212 (light emitting element), a transmission glass 214, a decoration roller 216, A contact roller unit 220 is provided. The light irradiation unit 20 irradiates the skin with light from the xenon tube 212.

  The light irradiation unit 20 is detachably attached to the apparatus main body 10. With this structure, for example, when the xenon tube 212 has deteriorated over time, it can be replaced with a new light irradiation unit 20.

  The casing 210 includes a skin contact surface 210a (first surface), an opening 210b (an opening provided in the main body having the first surface), a roller opening 210c, a touch sensor unit 210d (contact detection means), and a ventilation hole 210e. Is provided. The housing 210 accommodates the xenon tube 212, the transmission glass 214, and the contact roller unit 220.

  Skin contact surface 210 a is the front surface of housing 210. Skin contact surface 210a contacts the user's skin surface during the hair removal process. The surface of the skin contact surface 210a is preferably coated with glass or plastic so that it can move smoothly on the user's skin surface.

  The opening 210b is provided from the skin contact surface 210a toward the inside of the housing 210. Light from the xenon tube 212 is irradiated from the opening 210b. The opening 210b has a substantially rectangular shape. The long side of the opening 210b is along the rotation axis direction of a contact roller 226 (a roller portion that is rotatably provided with a part exposed from the first surface) included in the contact roller portion 220.

  The length of the short side of the opening 210b is “the length of the width along the direction orthogonal to the rotation axis of the contact roller 226”. Here, “along the direction perpendicular to the rotation axis of the contact roller 226” has the same meaning as “along the moving direction of the light-irradiating beauty device 1”. The “rotating shaft of the contact roller 226” will be described later as the contact roller shaft 225.

  The roller opening 210c is provided from the skin contact surface 210a toward the inside of the housing 210. A part of the contact roller 226 is exposed from the roller opening 210c. A part of the periphery of the roller opening 210 c is raised to accommodate a contact roller shaft 225 that is a rotation shaft of the contact roller 226.

  The touch sensor unit 210d is a part around the opening 210b in the skin contact surface 210a. The touch sensor unit 210d includes, for example, a capacitive touch sensor. The capacitive touch sensor may be either a surface type or a projection type. The touch sensor is electrically connected to the control board 130.

  When the skin surface of the user contacts the touch sensor unit 210d, a current flows or a voltage is applied between the touch sensor and the control board 130. The control board 130 senses whether or not the skin surface of the user is in contact with the periphery of the opening 210b by detecting the current and voltage. The touch sensor unit 210d may include an electronic circuit, convert these currents or voltages into digital signals, and output the digital signals to the control board 130. The touch sensor unit 210d may output a signal indicating the presence or absence of contact. For example, there is contact: 1 and no contact: 0.

  The touch sensor is not particularly limited as long as it can detect contact with the user's skin surface. The touch sensor unit 210d can include various types of touch sensors such as a resistive film method, a surface acoustic wave method, an infrared method, and an electromagnetic induction method. The touch sensor unit 210d can also include an illuminance sensor that detects the illuminance in the opening 210b. The illuminance sensor detects, for example, the illuminance in the opening 210b that changes when the opening 210b is blocked by the user's skin. The control board 130 can perceive whether or not the user's skin surface is in contact with the touch sensor unit 210d based on the detected illuminance.

  The ventilation hole 210e penetrates from the front surface of the housing 210 to the back surface. The ventilation hole 10d is an intake port. When the cooling fan 114 of the apparatus main body 10 is driven, outside air flows into the housing 210 from the ventilation holes 210e. This inflowing air cools the xenon tube 212. The air that flows in from the ventilation hole 210e flows into the apparatus main body 10.

The xenon tube 212 is disposed in the opening 210b.
The transmissive glass 214 is fitted into the opening 210b. The transmission glass 214 cuts off ultraviolet rays contained in the light of the xenon tube 212. The transmissive glass 214 prevents the user from inadvertently putting a finger or the like inside the opening 210b.

The decoration roller 216 is provided on a side surface of the casing 210 (a surface connecting the skin contact surface 210a and a surface facing the apparatus main body 10 on the opposite side).
The decoration roller 216 rotates corresponding to the rotation of the contact roller 226. The decoration roller 216 is disposed so as not to contact the user's skin.

The decoration roller 216 is a roller for grasping whether or not the contact roller 226 is rotating normally.
During the hair removal process, the contact roller 226 comes into contact with the user's skin surface. At this time, the contact roller 226 is hidden from the apparatus main body 10 and the casing 210 and is not visible to the user. In this case, it is difficult for the user to know whether the contact roller unit 220 is rotating normally. By looking at the decorative roller 216 that rotates, the user can indirectly know whether or not the contact roller unit 220 is rotating.

(About the contact roller 220)
As shown in FIGS. 4 and 5, the contact roller unit 220 includes a substrate 221, shaft holding bases 222 and 223, a decoration roller shaft 224, a contact roller shaft 225, a contact roller 226, a contact roller gear 227, a decoration roller gear 228, and a detection unit. 230 (signal output means).

  The substrate 221 holds the shaft holders 222 and 223, the decoration roller shaft 224, the contact roller shaft 225, the contact roller 226, the contact roller gear 227, the decoration roller gear 228, and the detection unit 230. An electronic circuit connected to the detection unit 230 is formed on the substrate 221. This electronic circuit includes a connection pin 221a for signal transmission / reception. The electronic circuit includes electronic elements (for example, an IC chip, a resistance element, a capacitor, and a coil element) not shown.

  The shaft holding bases 222 and 223 are columns. The shaft holding bases 222 and 223 are provided on the substrate 221. The shaft holding bases 222 and 223 face each other with a predetermined distance. The shaft holding bases 222 and 223 are spaced apart along the long side of the opening 210b shown in FIG.

The shaft holding base 222 includes through holes 222a and 222b.
The through holes 222a and 222b are arranged in series in order from the bottom (substrate 221 side) to the top. The decorative roller shaft 224 is rotatably inserted into the through hole 222a. The contact roller shaft 225 is rotatably inserted into the through hole 222b.

  The shaft holding base 223 includes through holes 223a and 223b. The through holes 223a and 223b are arranged in series from the bottom (substrate 221 side) to the top. The arrangement position (height from the substrate 221) of the through hole 223a corresponds to the through hole 222a. Similarly, the arrangement position of the through hole 223b corresponds to the through hole 222b.

The decorative roller shaft 224 is rotatably inserted into the through hole 223a. The contact roller shaft 225 is rotatably inserted into the through hole 223b.
The lengths of the decoration roller shaft 224 and the contact roller shaft 225 in the longitudinal direction are longer than the distance between the shaft holding bases 222 and 223. Therefore, the left and right ends of the decorative roller shaft 224 and the left and right ends of the contact roller shaft 225 are positioned outside the shaft holding bases 222 and 223, respectively.

  Locking members (not shown) are provided at portions of the contact roller shaft 225 and the decorative roller shaft 224 that are located outside the shaft holding bases 222 and 223. The locking member prevents the contact roller shaft 225 from falling off the shaft holding bases 222 and 223. The locking member is not particularly limited as long as it is a structure that can prevent this dropout. The locking member is, for example, a flange or nut wider than the diameter of the through holes 222a, 222b, 223a, and 223b. The flanges and nuts are caught on the shaft holding bases 222 and 223, thereby preventing the dropping.

Decoration rollers 216 are attached to the left and right ends of the decoration roller shaft 224, respectively. The decoration roller shaft 224 and the decoration roller 216 rotate integrally.
The contact roller 226 has a cylindrical shape. The contact roller 226 is in contact with the user's skin surface. The contact roller 226 is disposed at the center of the contact roller shaft 225. The contact roller 226 rolls on the skin surface. The contact roller 226 and the contact roller shaft 225 rotate integrally.

  The contact roller 226 is made of rubber or plastic. The surface of the contact roller 226 is subjected to processing (for example, uneven processing) for increasing the frictional force on the user's skin surface.

  The contact roller gear 227 is provided on the contact roller shaft 225. The contact roller gear 227 is located between the contact roller 226 and the shaft holding base 223. The contact roller gear 227 and the contact roller shaft 225 rotate integrally. The contact roller gear 227 is in contact with the decorative roller gear 228. When the contact roller gear 227 rotates, the decorative roller gear 228 also rotates.

  The decoration roller gear 228 is provided on the decoration roller shaft 224. The decorative roller gear 228 and the decorative roller shaft 224 rotate integrally.

(About the detection unit 230)
The detection unit 230 includes a holding unit 231, detection targets 232a and 232b, and a sensor 233.
The holding portion 231 is provided on the decorative roller shaft 224. The holding portion 231 is sandwiched between the decorative roller gear 228 and the shaft holding base 222. The holding portion 231 and the decorative roller shaft 224 rotate integrally.

  As shown in FIG. 5, the holding portion 231 includes holding holes 231a and 231b. The holding unit 231 accommodates the detection targets 232a and 232b. The holding part 231 has a cylindrical shape.

  The holding holes 231a and 231b are respectively provided on the side surfaces of the holding portion 231. The holding holes 231 a and 231 b are provided from the side surface of the holding part 231 toward the center of the holding part 231. The holding holes 231 a and 231 b are shifted from each other by 180 ° in the circumferential direction of the holding portion 231. That is, the two holding holes 231a and 231b are located on opposite sides of the decoration roller shaft 224.

  The detection targets 232a and 232b are disposed in the holding holes 231a and 231b, respectively. The detection targets 232a and 232b are, for example, magnets. Here, the detection targets 232a and 232b are neodymium magnets.

  The sensor 233 is fixed at a position on the substrate 221 corresponding to the holding unit 231. The sensor 233 detects the magnetic field of the detection targets 232a and 232b. A signal (current or voltage) corresponding to the strength of the magnetic field detected by the sensor 233 flows or is applied between the sensor 233 and the control board 130.

Here, “flowing or being applied between the sensor 233 and the control board 130” is defined as “the detection unit 230 outputs a signal to the control board 130”. The control board 130 controls the light emission of the xenon tube 212 based on the output of this signal.
The sensor 233 includes, for example, a hall element. The control board 130 detects the voltage generated in the Hall element.

  The sensor 233 may include an electronic circuit, and a current or voltage may be converted into a digital signal and output to the control board 130. The sensor 233 can also compare a current or voltage value with a predetermined threshold. Corresponding to the result of this comparison, the sensor 233 may output a digital signal indicating that the detection targets 232a and 232b have been detected to the control board 130. For example, the sensor 233 indicates that “1: detection target is detected” when the current or voltage value is equal to or greater than the threshold value, and “0: detection target is not detected” when the current or voltage value is lower than the threshold value. Output a signal.

  In the contact roller unit 220 configured as described above, the contact roller shaft 225 and the contact roller gear 227 rotate integrally as the contact roller 226 rotates. Further, the contact roller gear 227 rotates the decorative roller gear 228. As a result, the decorative roller shaft 224, the holding portion 231 and the decorative roller 216 also rotate.

  In summary, when the contact roller 226 rotates, the holding portion 231 and the decoration roller 216 rotate.

  When the holding unit 231 rotates, the detection target 232a approaches the sensor 233. The sensor 233 detects the magnetic field of the detection target 232a. When the holding unit 231 further rotates (here, approximately 180 °), the detection target 232b approaches the sensor 233 this time. This time, the sensor 233 detects the magnetic field of the detection target 232b.

  Corresponding to the rotation of the holding unit 231, the sensor 233 sequentially repeats a signal that detects the detection target 232 a and a signal that detects the detection target 232 b in order, and outputs them to the control board 130. When this signal is input to the control board 130, the xenon tube 212 emits light.

(Regarding relationship between holding portion 231 and opening 210b)
Next, the relationship between the holding portion 231 and the opening 210b of the apparatus main body 10 will be described with reference to FIG. FIG. 6 shows a cross section of the holding portion 231 and shows the opening 210b from the front.

  The dashed line in the figure is an imaginary line indicating that the opening 210b, the sensor 233, and the holding unit 231 illustrated by a solid line correspond to each other, and that the opening 210b, the sensor 233, and the holding unit 231 illustrated by a broken line correspond to each other. It is.

  The opening 210b has a dimension of vertical width v [mm] × horizontal width h [mm]. The vertical width v [mm] is the length of the short side of the opening 210b, and the horizontal width h [mm] is the length of the long side of the opening 210b. The cross section of the holding portion 231 has a circular shape with a circumferential length c [mm] (not shown).

Here, the relationship between the circumferential length of the holding portion 231 and the vertical width of the opening 210b is expressed by the following Equation 1.
v = c / a (1)
v: Vertical width of the opening 210b.
c: the circumferential length of the holding portion 231.
a: Variable

  One of the vertical width v and the circumferential length c may have an error of several [mm] relative to the other. The variable a is a number greater than 0. Here, the variable a is 2 corresponding to the number of detection targets.

  “C / 2” means the length of a half circumference of the holding portion 231. That is, the length of the half circumference of the holding portion 231 means substantially the same as the vertical width v. When the holding unit 231 is rotated by a half circumference, the light-irradiating beauty device 1 is moved on the user's skin by the vertical width v [mm] of the opening 210b.

Next, the number of detection targets and the rotation angle θ1 of the holding portion 231 necessary for light emission of the xenon tube 212 in this embodiment will be described.
The number of detection targets and the rotation angle θ1 of the holding portion 231 necessary for light emission of the xenon tube 212 are expressed by the following formula 2.
θ1 = 360 / a (2)
θ1: Rotation angle required from the first light emission to the second light emission of the xenon tube 212 a: Number of detection targets.

Here, the number of detection targets is 2 (detection targets 232a and 232b). Therefore, the rotation angle required from the first light emission to the second light emission is 180 °.
When the holding unit 231 is rotated by the rotation angle θ1, the light-irradiating beauty device 1 is moved on the user's skin by the vertical width v [mm] of the opening 210b.

(Regarding the control board 130)
Next, the function of the control board 130 will be described with reference to FIG. FIG. 7 is a functional block diagram of the control board 130.

  As illustrated in FIG. 7, the control board 130 includes a memory unit 131, a detection control unit 132, a fan control unit 133, a voltage conversion unit 134, and a light emission control unit 135. These functions are realized by circuit elements (for example, arithmetic, memory IC chip, resistance element, capacitor, coil element). The control board 130 can also include a charging circuit for a secondary battery.

  The memory unit 131 stores firmware, various threshold values, a conversion table, and the like in advance.

The detection control unit 132 is connected to the operation unit 112 shown in FIG. 1, the touch sensor unit 210d shown in FIG. 2, and the detection unit 230 shown in FIG. The detection control unit 132 detects an operation of the operation unit 112 by the user. An analog signal or a digital signal output from the touch sensor unit 210 d or the detection unit 230 is input to the detection control unit 132.
When the detection unit 230 includes a Hall element, the detection control unit 132 can also detect a voltage generated in the Hall element.

  The detection control unit 132 can compare the magnitude of the voltage or current input from the detection unit 230 or the touch sensor unit 210 d with the threshold value stored in the memory unit 131. When the current (or voltage) input from the touch sensor unit 210d is larger than, for example, a threshold value, the detection control unit 132 sets a “flag indicating that the user's skin surface is in contact with the periphery of the opening 210b” ( For example, “1” of the digital signal is held in the memory).

  When the current (or voltage) input from the detection unit 230 is larger than, for example, a threshold value, the detection control unit 132 sets a “flag for causing the xenon tube 212 to emit light” (for example, “1” of the digital signal is held in the memory). ). If it is smaller than the threshold value, a “flag not to cause the xenon tube 212 to emit light” is set (for example, “0” of the digital signal is held in the memory).

  This flag may be set based on a digital signal input from the detection unit 230 or the touch sensor unit 210d (for example, a signal indicating “1: detection target is detected”, “0: detection target is not detected”). Good.

  The fan control unit 133 is connected to the cooling fan 114 shown in FIG. The fan control unit 133 turns driving of the cooling fan 114 on and off.

  The voltage conversion unit 134 converts electric power obtained from a commercial power source or a secondary battery. This conversion is, for example, rectifying an alternating current into a direct current, boosting or dropping a voltage. The electric power converted by the voltage converter 134 is used for light emission of the xenon tube 212 and the like.

The light emission control unit 135 controls the memory unit 131, the detection control unit 132, the fan control unit 133, and the voltage conversion unit 134.
The light emission control unit 135 includes a capacitor that temporarily stores electricity supplied to the xenon tube 212 and a charging circuit for the capacitor.

  The light emission control unit 135 supplies the electricity stored in the capacitor to the xenon tube 212. As a result, the xenon tube 212 emits light.

(Light emission control example 1)
The light emission control unit 135 causes the xenon tube 212 to emit light when all of the following conditions (1) to (3) are met.

(1) A “flag indicating that the user's skin surface is in contact with the opening 210b” stands.
(2) The “flag for causing the xenon tube 212 to emit light” is set.
(3) The electricity necessary for making the xenon tube 212 emit light is stored in the capacitor.

(Light emission control example 2)
The light emission control unit 135 causes the xenon tube 212 to emit light even when the following conditions (1) and (2) are met.
(1) The detection control unit 132 detects an operation of the operation unit 112 by a user (for example, a manual light emission button pressing operation).
(2) The electricity necessary for making the xenon tube 212 emit light is stored in the capacitor.

  As described above, the light-irradiating beauty device 1 can perform the hair removal process by irradiating the skin with the light from the xenon tube 212.

(effect)
According to the light irradiation type beauty apparatus 1 configured as described above, it is possible to reduce the troublesomeness of the operation during the hair removal process.
(Specific examples of effects)

(1) By providing the contact roller 226, the light irradiation type beauty device 1 can be smoothly moved on the skin surface by the contact roller 226.

  Here, an example of the operation at the time of hair removal processing of a conventional product (hereinafter simply referred to as “device”) will be described. This apparatus includes a flash lamp and an irradiation port for irradiating the skin surface with light from the flash lamp. In such an apparatus, 1) after irradiating the part to be subjected to hair removal treatment with the light of the flash lamp, 2) to lift the apparatus once away from the skin surface, and 3) to the part to be subjected to another hair removal treatment. 4) The hair removal treatment can be performed by irradiating the newly contacted skin surface with the light of the flash lamp.

In this case, the lifting of the apparatus and the contact with the site to be subjected to the hair removal process are repeated as many times as the number of sites to be subjected to the hair removal process.
The operation of bringing the lifted device into contact with the site where the hair removal process is desired is a three-dimensional operation of vertical, horizontal, and depth for the user. In this case, there is a case where the device comes into contact with a place different from the place the user thinks, or the arm holding the device gets tired.

  In this hair removal treatment method, the user needs to determine the position of the irradiation port for each site where the hair removal treatment is to be performed. This positioning may take time due to fatigue.

  In the light irradiation type beauty apparatus 1, by providing the contact roller 226, the light irradiation type beauty apparatus 1 can be moved one-dimensionally along the skin surface smoothly on the skin surface. Accordingly, it is possible to prevent the light-irradiating beauty apparatus 1 from coming into contact with a place different from the place that the user has thought of, and the arm holding the light-irradiating beauty apparatus 1 from getting tired. As a result, the position of the opening 210b resulting from the contact work can be quickly determined.

(2) In the light irradiation type beauty apparatus 1, the detection unit 230 rotates in synchronization with the rotation of the contact roller 226, and the xenon tube is moved every time the light irradiation type beauty apparatus 1 moves by the vertical width v [mm] of the opening 210b. 212 emits light. As a result, the light from the xenon tube 212 can be continuously applied to the hair removal target for each vertical width of the opening 210b.

  Thereby, irradiation unevenness can be reduced, and the user does not need to press the trigger button of the xenon tube 212 for each part where hair removal processing is desired. Further, it is not necessary to be aware that the opening 210b is positioned for each part where the hair removal process is desired.

  One meaning of the irradiation unevenness is that “the area on the skin surface irradiated with light by the first light emission of the xenon tube 212 is separated from the area on the skin surface irradiated with light by the second light emission. Will create a range that is not irradiated. " Since the hair removal effect cannot be obtained in the range where this light is not irradiated, it is necessary to irradiate the xenon tube 212 again.

  One meaning of the irradiation unevenness is “the area on the skin surface irradiated with light by the first light emission of the xenon tube 212 overlaps the area on the skin surface irradiated with light by the second light emission. That is, the portion where the light of the tube 212 is irradiated more than necessary than the other hair removal target portions will come out.

(Modification 1)
The light irradiation type beauty device 1 according to the first embodiment has been described above. The light irradiation type beauty apparatus 1 can be variously modified.

(1) The detection targets 232a and 232b and the sensor 233 may be interchanged. That is, the holding unit 231 includes two sensors corresponding to the detection targets 232a and 232b, and the substrate 221 includes one detection target corresponding to the sensor 233.

(2) The detection targets 232a and 232b may be light emitting elements (for example, LEDs). The sensor 233 may be a light receiving element (for example, a photodiode).

(3) The contact roller 226 or the contact roller shaft 225 may include each element of the detection unit 230. In this case, the light-irradiating beauty device 1 is a decorative roller shaft 224. The decoration roller gear 228 and the decoration roller 216 may not be provided. As a result, the light irradiation part 20 can be made thin.

(4) The light-irradiating beauty device 1 may be provided with either one of the detection targets 232a and 232b. Furthermore, the circumferential length of the holding portion 231 may be shorter than the vertical width of the opening 210b. For example, the length may be half. In this case, the light emission control unit 135 causes the xenon tube 212 to emit light each time the holding unit 213 rotates twice.

(5) The detection unit 230 may be a mechanical contact sensor.
(6) The skin contact surface 210a may include an electrode for allowing current to flow through the user's skin surface. By passing an electric current through the user's skin, muscles can be forced to exercise. As a result, it is possible to expect the effect of removing the waste products and giving the skin “gloss” and “tension”.

(7) The shape of the opening 210b may be changed (for example, a rectangular shape, a triangular shape, a trapezoidal shape, a perfect circular shape, an elliptical shape, a star shape, etc.).

(8) The light irradiation type beauty apparatus 1 may include an acceleration sensor. The acceleration sensor detects that the light-irradiating beauty device 1 is moved. The light emission control unit 135 causes the xenon tube 212 to emit light when the acceleration sensor detects that “the light irradiation type beauty apparatus 1 is moved”, and when the light irradiation type beauty apparatus 1 is not moved. Does not cause the xenon tube 212 to emit light (improves safety).

(9) The apparatus main body 10 and the light irradiation unit 20 may be integrally formed.
(10) The light irradiation unit 20 may include a halogen lamp or an LED lamp.

(11) A temperature sensor may be disposed in the vicinity of the xenon tube 212. The temperature sensor is, for example, a thermistor. The light emission control unit 135 causes the xenon tube 212 to emit light corresponding to the temperature of the temperature sensor. As a result, failure of the xenon tube 212 due to high temperature can be prevented.

(12) An attachment with a filter that covers the opening 210 b of the light irradiation unit 20 may be attached to the housing 210. The attachment is attached to the casing 210 by a magnet, for example. The filter is any one of a band pass filter, a low pass filter, and a high pass filter. Light of a specific wavelength can be extracted and supplied to the user's skin surface. The effect of beautifying the skin with light of this specific wavelength can be expected.

(13) The housing 210 and the attachment of the above (12) may include a Peltier element. The Peltier element gives a warm and cool feeling to the user's skin. The Peltier element can lower the temperature of the skin warmed by the light from the xenon tube 212.

(14) The apparatus main body 10, the skin contact surface 210a, or the attachment of the above (12) may include an electrode. This electrode is used, for example, for ion introduction and ion derivation.

Iontophoresis refers to a cosmetic method aimed at penetrating vitamin C derivatives and placenta deep into the skin using a weak current.
Ion derivation refers to a cosmetic method that aims to remove dirt (for example, old keratin) on the skin by passing a weak current in the opposite direction to ion introduction.

For example, the electrode of the apparatus body 10 is an anode, and the electrode of the housing 210 is a cathode. The user can cause a weak current to flow through the user's body by grasping the electrode of the apparatus body 10 and applying the electrode of the housing 210 to the skin surface.
(15) The contact roller shaft 225 may include the decoration roller 216.

[Second Embodiment]
Next, the light irradiation type beauty apparatus 2 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a schematic diagram of a detection unit 330 (signal output means) included in the light-irradiating beauty device 2 of the second embodiment.

  In FIG. 8, the same components as those in the first embodiment shown in FIG. 5 are given the same reference numerals, and the description thereof is omitted.

The detection unit 330 corresponds to the detection unit 230 of the first embodiment. The detection unit 330 includes detection targets 232a and 232b and sensors 333a and 333b.
The detection targets 232a and 232b are shifted from each other by 180 ° in the circumferential direction of the holding portion 231 and are shifted from each other along the long axis direction of the holding portion 231 (the direction in which the 224 decorative roller shaft 224 extends).

  The sensors 333a and 333b correspond to the sensors 233a and 233b. The sensor 333a is fixed at a position on the substrate 221 corresponding to the detection target 232a. The sensor 333a detects the magnetic field of the detection target 232a.

  The sensor 333b is fixed at a position on the substrate 221 corresponding to the detection target 232b. The sensor 333b detects the magnetic field of the detection target 232b.

  In the light irradiation type beauty apparatus 2, the light emission control unit 135 (see FIG. 7) can individually identify the sensors 333a and 333b. The light emission control unit 135 causes the xenon tube 212 to emit light based on the signals output from the sensors 333a and 333b.

  When the light emission control unit 135 causes the xenon tube 212 to emit light based on the signal output from the sensor 333a, the light emission control unit 135 does not cause the xenon tube 212 to emit light unless there is a signal output from the sensor 333b.

  That is, the light emission control unit 135 of this embodiment does not cause the xenon tube 212 to emit light even if the second and subsequent signals are input when signals are continuously output from the same sensor (for example, the sensor 333a).

  The light-irradiating beauty device 2 may be operated so as to reciprocate on the skin surface. In the forward path, for example, the xenon tube 212 emits light once based on a signal output from the sensor 333a. Thereafter, the light-irradiating beauty device 2 is immediately moved in the reverse direction (return direction).

  Since the sensor 333a detects the detection target 232a in the return path, the sensor 333a continuously outputs the detection signal in the forward path and the return path. When the xenon tube 212 emits light based on the signal in the return path, the light from the xenon tube 212 is irradiated once again within a short time to the portion irradiated once in the forward path.

In some cases, the hair removal process has already been performed in the forward path, and the hair removal effect may be weak even if light from the xenon tube 212 is irradiated again in the return path. In some cases, power used for light emission of the xenon tube 212 is wasted.
In the light irradiation type beauty apparatus 2, such waste of electric power can be prevented.
It is desirable that the control of the light emission control unit 135 in the light-irradiating beauty device 2 with respect to the xenon tube 212 can be released at any time by the user operating the operation unit 112.

FIG. 9 is a schematic diagram showing a second modification of the light irradiation type beauty apparatus 1 or the light irradiation type beauty apparatus 2.

  The light-irradiating beauty device 1 may include a plurality of contact roller shafts 225 corresponding to the contact rollers 226a to 226g (see contact roller shafts 225a to 225g in FIG. 9). In this case, the contact rollers 226a to 226g rotate independently of each other.

  The contact roller shafts 225a, 225b and 225c can be integrated. In this case, the contact rollers 226a, 226b and 226c rotate integrally. The same applies to the contact roller shafts 225h and 225d. In this case, the contact rollers 226h and 226d rotate integrally.

The first casing unit 310 and the second casing unit 320 rotate relative to each other about the central axis P as a rotation axis.

  When the user removes the force, the rotation of the first connection portion 31b and the second connection portion 31c (the first housing portion 310 and the second housing portion 320) stops. The hinge 31 is connected to the first connecting portion 31b and the second connecting portion 31c (the first connecting portion 31c at the time when the user releases the force until the user applies force to the first housing portion 310 and the second housing portion 320 next time. The opening angle of the housing part 310 and the second housing part 320) is maintained.

  In addition, the 1st connection part 31b and the 2nd connection part 31c may rotate in the direction of arrow Ar of FIG.

  When the light-irradiating beauty device 3 is pushed or pulled on the skin surface or pressed against the skin surface, the first connection portion 31b and the second connection portion 31c are hard enough to rotate so that they do not rotate with each other (rotation). It is desirable that the hinge 31 has a resistance strength of

  The light-irradiating beauty device 3 includes a lock mechanism that detects that the light-irradiating beauty device 3 is pushed and pulled on the skin surface or is pressed against the skin surface by a sensor and prevents the hinge 31 from rotating. May be. As the lock mechanism, for example, a mechanism that inhibits the rotation of the hinge 31 by an electromagnetic valve using a solenoid can be considered.

The sensor unit 324 is a position sensor for detecting the opening angle of the first connection unit 31b and the second connection unit 31c.
The sensor unit 324 outputs a detection result (for example, a digital signal indicating an angle value or an analog signal based on current or voltage) to the control board 315.

  The sensor unit 324 includes, for example, a rotary encoder. The rotary encoder is attached to the hinge 31 and detects the rotation angle of the second connection part 31c with respect to the first connection part 31b.

  The sensor unit 324 may include an illuminance sensor. The illuminance sensor, for example, measures the illuminance in the hinge housing part 320e. The measured illuminance is converted into an opening angle of the first casing unit 310 and the second casing unit 320.

  The sensor unit 324 may detect the opening angle of the first housing unit 310 and the second housing unit 320 instead of the opening angle of the first connection unit 31b and the second connection unit 31c. A hall sensor may be provided as the sensor unit 324.

(Regarding the control board 315)
Next, the function of the control board 315 will be described with reference to FIG. FIG. 13 is a functional block diagram of the control board 315. The control board 315 corresponds to the control board 130 shown in FIG.

These functions are realized by a control circuit formed by circuit elements (for example, arithmetic operation, memory IC chip, resistance element, capacitor, coil element).

  The light emission control unit 316 corresponds to the light emission control unit 135. The light emission control unit 316 calculates the opening angle of the first connection unit 31b and the second connection unit 31c (or the first housing unit 310 and the second housing unit 320) based on the calculation result output from the sensor unit 324. To do.

  An example of this calculation is to refer to a conversion table stored in the memory unit 131 and convert a detection result (for example, a current value, a voltage value, or an illuminance value) output from the sensor unit 324 into an angle. . When the detection result is a digital signal indicating an angle value, this conversion step can be omitted.

  The light emission control unit 316 switches the light emission pattern of the xenon tube 212 in accordance with the opening angle.

(Example of light emission pattern)
(1) First light emission pattern (opening angle: 0 degree)
As shown in FIG. 11, when the opening angle of the first connection part 31b and the second connection part 31c is 0 degree, the light emission control part 316 has the same light emission pattern as that of the first and second embodiments or each modification. Then, the xenon tube 212 is caused to emit light. That is, the light emission control unit 316 causes the xenon tube 212 to emit light according to the rotation of the contact roller 226.

(2) Second light emission pattern (opening angle: 45 degrees or more)
As shown in FIG. 12, when the opening angle of the first connection portion 31 b and the second connection portion 31 c is 45 degrees or more, the light emission control unit 316 causes the xenon tube 212 to emit light corresponding to the rotation of the contact roller 226. Instead, the xenon tube 212 is caused to emit light only when the operation switch 322 is pressed. In this case, when the operation switch 322 is pressed once, the xenon tube 212 emits light once.

(3) Third light emission pattern (opening angle: larger than 0 degree and smaller than 45 degrees)
When the opening angle of the first connection portion 31b and the second connection portion 31c is greater than 0 degree and less than 45 degrees, the light emission control unit 316 does not cause the xenon tube 212 to emit light in response to the rotation of the contact roller 226. When the operation switch 322 is pressed, the xenon tube 212 is caused to emit light continuously. In this case, when the operation switch 322 is pressed once, the xenon tube 212 emits light a plurality of times.

(4) Modification Example of Light Emission Pattern The opening angle that is a condition for causing the xenon tube 212 to emit light with the first light emission pattern is not limited to 0 degrees. For example, in the case of 0 degree to 15 degrees, You may comprise so that it may light-emit with the light emission pattern.

  The pattern corresponding to the opening angle may be further finely divided. Further finely divided patterns can be differentiated by changing the interval from the light emission to the next light emission, the number of times of light emission, or the light emission intensity of the xenon tube 212.

  When the emission intensity of the xenon tube 212 is varied, for example, the first pattern is weaker than the other emission patterns, the second emission pattern is the strongest of the emission patterns, and the third emission pattern is The xenon tube 212 is controlled to have an intermediate strength.

  Further, the xenon tube 212 continuously emits light (continuously flashes) while the operation switch 322 is pressed, and the xenon tube 212 stops emitting light when the operation switch 322 is not pressed. Good.

  Alternatively, the xenon tube 212 may emit light in response to the rotation of the contact roller 226 while the operation switch 322 is being pressed.

  In any of the patterns described above, it is desirable not to cause the xenon tube 212 to emit light when the user's skin surface is not in contact with the periphery of the opening 210b of the light irradiation unit 20a.

(About effect)
According to the light irradiation type beauty apparatus 3 configured as described above, it is possible to reduce the troublesomeness of the operation during the hair removal process.

(Concrete example)
(1) As shown in FIG. 11, according to the light irradiation type beauty device 3 in which the opening angle of the first connection part 31b and the second connection part 31c is 0 degrees, the first and second embodiments and the respective modifications The same effect as the example can be obtained.

  (2) According to the light-irradiating beauty device 3, the user has the most opening angle of the first housing unit 310 and the second housing unit 320 by the hinge 31 in accordance with the site where hair removal processing is desired. It can be adjusted to an easy angle (improved operability in hair removal treatment).

  In order to effectively irradiate the skin surface to be subjected to the hair removal treatment with light from the xenon tube 212, it is desirable that the opening 210b of the light irradiation unit 20a is in contact with the skin surface in a horizontal state as much as possible. . When abutting in this way, the angle formed between the first housing portion 310 and the skin surface is inevitably a substantially right angle.

  Although it is easy to make the angle formed between the first housing part 310 and the skin surface by raising and lowering the shoulders and elbows, bending and stretching, and the rotation of the wrist, the human body has many curved surfaces and is excluded. Since the distance from the shoulder of the skin surface of the hair target varies, a burden may be applied to the shoulder, elbow, and wrist depending on the part that the user wants to remove.

  Therefore, depending on the part where the user wants to remove hair, as shown in FIG. 11, the first housing part 310 and the second housing part 320 are linear (the first housing part 310 and the second housing part If the opening angle of 320 is approximately 180 degrees), as shown in FIG. 12 when the burden on the elbow or wrist is small, the first housing 310 and the second housing 320 are relatively The person who was rotating may have less burden on the shoulders, elbows and wrists.

  For example, when performing hair removal on a part that is longer than the other side of the body, such as legs and arms, and that is far from the shoulder of the light-irradiating beauty device 3, the first housing part When the 310 and the second housing 320 are arranged in a straight line, the burden on the shoulder, elbow, and wrist is less, and the operability of the light-irradiating beauty device 3 is often better.

  When hair removal is performed on a side or face, such as a leg or arm, which is smaller in area, and when the hair-irradiating beauty device 3 has a shorter distance from the shoulder than a leg or arm, When the second casing 320 is rotated with respect to the one casing 310, the burden on the shoulder, elbow, and wrist is less, and the operability of the light irradiation type beauty device 3 is often good.

  In addition, when removing hair at a blind spot such as the back and neck muscles, the direction where the second housing part 320 is rotated with respect to the first housing part 310 is more effective on the shoulders, elbows and wrists. In many cases, the burden is small and the operability of the light-irradiating beauty device 3 is good.

According to the light irradiation type beauty device 3, the angle of the second housing part 320 with respect to the first housing part 310 can be varied in accordance with the position of the skin surface to be subjected to the hair removal process, so that the operability is good. The hair removal treatment can be applied to various parts of the body in the state.
By improving the operability, it is possible to prevent the user from taking care of the hair removal process.

  (3) According to the light-irradiating beauty device 3, as shown in FIG. 12, when the first housing part 310 and the second housing part 320 are relatively rotated, the operation switch 322 is exposed. Since the operation switch 322 is disposed in the second housing unit 320 and is located near the user's finger, the user can easily press the operation switch 322.

  Further, as already described, the operation switch 322 is inclined at a predetermined angle with respect to the skin contact surface 210a as a whole. This inclination makes it easier for the operation switch 322 to hit and push the user's finger.

  (4) According to the light-irradiating beauty device 3, the light emission pattern of the xenon tube 212 is switched in accordance with the opening angle of the second connection portion 31c with respect to the first connection portion 31b. There is no need to switch. As a result, the operability related to switching of the light emission pattern of the xenon tube 212 is improved.

  (5) According to the light irradiation type beauty apparatus 3, the ventilation hole 310e is provided in the rear-end part 310b including the opposing surface 310c of the 1st housing | casing part 310, for example, as shown in FIG. When the housing part 310 and the second housing part 320 are arranged in a straight line, the tip part 320a of the second housing part 320 is covered so as not to touch the user's finger.

  For this reason, it can prevent that the airflow in the 1st housing | casing part 310 is inhibited by a user's finger | toe. The xenon tube 212 can be cooled stably.

  As described above, a slight gap is provided between the ventilation hole 310e and the second housing part 320. For this reason, the ventilation hole 310e is not blocked by the second housing part 320.

  (6) As shown in FIG. 12, the facing surface 310 c is inclined so as to be separated from the user's finger (for example, the thumb F in FIG. 12) holding the second housing part 320. For this reason, it is possible to prevent the ventilation hole 310e from being blocked by the user's finger.

As a result, it is possible to prevent the airflow in the first housing unit 310 from being obstructed by the user's finger. The xenon tube 212 can be cooled stably.

For example, a click hinge whose angle can be changed in stages may be adopted as the hinge 31.
For example, the apparatus main body 30 and the light irradiation unit 20a may be integrally formed.
Instead of light emission from the xenon tube 212, the hair may be removed with a laser.
The light irradiation part 20a may have a Peltier element, for example, and may warm or cool the skin surface. The contact roller 226 may have, for example, a cylindrical shape, a polygonal column shape, or a spherical shape.

  The light irradiation unit 20a may include an electrode, and a current may be applied to the skin surface for the purpose of exercising the muscle to force the muscle to contract. The forced contraction movement of the muscle due to the electric current is referred to as Electrical Muscle Stimulation (EMS). The current is preferably an alternating current, and the frequency is not particularly limited.
