  Hereinafter, the same or equivalent components, members, and processes shown in the drawings are denoted by the same reference numerals, and repeated descriptions are appropriately omitted. In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. Also, in the drawings, some of the members that are not important for describing the embodiment are omitted.

  1 to 5 are external views of the beauty roller 1. 1 is a top view of the cosmetic roller 1, FIG. 2 is a bottom view of the cosmetic roller 1, FIGS. 3 and 4 are front views showing the usage state of the cosmetic roller 1, and FIG. 5 is a right side view showing the state of the cosmetic roller 1. It is. The beauty roller 1 includes two rollers 10, a handle 20, a display unit 28, and an imaging unit 40.

  Each roller 10 is a rotating body rotatably supported by a bifurcated portion 21 on one end side of the handle 20. Each roller 10 is formed in a substantially spherical shape in the present embodiment, but may be formed in a substantially elliptical shape, a substantially cylindrical shape, or other shapes.

  Each roller 10 is provided such that the interval between the rotation axes X increases as the distance from the handle 20 increases. Accordingly, when the beauty roller 1 is moved in the direction of arrow R in the state where the roller 10 is pressed against the skin 3 as shown in FIG. 5, the two rollers 10 cause the gap between the two rollers 10 as shown in FIG. The skin 3 is picked up so that it may be caught in. On the contrary, when the beauty roller 1 is moved in the direction of the arrow L in the state where the roller 10 is pressed against the skin 3 as shown in FIG. 5, the two rollers 10 cause the gap between the two rollers 10 as shown in FIG. The skin 3 is pushed out. That is, the two ways of picking up and spreading the skin 3 are possible. When the skin 3 is picked up or spread out, blood flow in the contact portion and circulation of lymph fluid are promoted. In addition, the skin is lifted up and tensioned.

  The display unit 28 is provided on the upper surface of the handle 20. In particular, the display unit 28 is provided at a position that avoids a portion gripped by the user when the beauty roller 1 is used for its original purpose (that is, when the roller 10 is pressed against the skin 3 and rolled). Thereby, the display on the display unit 28 can be confirmed even when the handle 20 is held. The display unit 28 is a touch panel display device such as a liquid crystal panel or an organic EL panel, and displays information on a screen and accepts a user operation input.

  The imaging unit 40 is a camera for acquiring a visible light image, and includes an imaging lens and a solid-state imaging device (for example, a CCD image sensor or a CMOS image sensor). The solid-state imaging device generates an image signal corresponding to an image formed by the imaging lens. An image signal generated by the solid-state imaging device is sent to a control unit (described later).

  The imaging unit 40 is provided on the lower surface of the bifurcated portion 21 of the handle 20. FIG. 6 is a view of the state where the skin 3 is picked up by the beauty roller 1 as seen from the beauty roller 1 side, particularly from the imaging unit 40 side. The imaging unit 40 is disposed so that the imaging region includes a portion of the skin 3 picked up by the two rollers 10 (portion surrounded by a dotted line).

  The imaging unit 40 is configured not to be focused beyond the necessary farthest distance. That is, the imaging unit 40 is configured so as not to be focused beyond the distance from the imaging unit 40 to the skin 3 that is the subject when the roller 10 is pressed against the skin 3. As an example, the subject distance of the imaging unit 40 is 2 mm to 10 mm. Thereby, it can prevent that the imaging part 40 of the beauty roller 1 is used for a sneak shot.

  Returning to FIGS. 1 to 5, at least one light source 41 for illuminating the imaging region is provided around the imaging unit 40. In FIG. 2, two light sources 41 are provided so as to sandwich the imaging unit 40. In order to image the picked up portion of the skin 3 (that is, a curved surface portion), if the light source 41 is provided only on one side of the imaging unit 40, a shadow is likely to be formed, but the imaging unit 40 is sandwiched as shown in FIG. Since the light source 41 is provided on the screen, the generation of shadows is suppressed. The light source 41 is, for example, an LED (light emitting diode).

  A plurality of display lamps (for example, LEDs) 26 are provided on the upper surface of the handle 20. The plurality of display lamps 26 are arranged in a V shape, and a display lamp 26b larger than the other display lamps 26a is provided at a position corresponding to the bottom of the V shape. The display lamp 26 is display-controlled as will be described later.

  7 is a cross-sectional view taken along line AA in FIG. The beauty roller 1 further includes a shaft 14, a heater 60, a first fixed side wiring member 32 a to a fourth fixed side wiring member 32 d that are collectively referred to as a fixed side wiring member 32, and a first that is collectively referred to as a movable side wiring member 34. The first movable side wiring member 34 a to the fourth movable side wiring member 34 d and a slip ring mechanism 70 are further provided. The roller 10 includes a base portion 11 and a cover portion 12.

  The base portion 11 and the shaft 14 are fixed to each other. The base portion 11 and the shaft 14 are particularly in a state where the shaft 14 enters the roller 10 and the center axis of the shaft 14, the rotation axis X of the roller 10, and the center axis of the shaft 14 substantially coincide with each other. Fixed to each other. The opposite side of the shaft 14 from the roller 10 is rotatably supported by a bearing (not shown) fixed to the handle 20. That is, the roller 10 and the shaft 14 are rotatably supported by the handle 20, and rotate integrally with the handle 20 about the center axis of the shaft 14 and thus the rotation axis X of the roller 10.

  The cover portion 12 is a member that occupies most of the outer surface of the roller 10 and is joined to the cover portion 12 with an adhesive. The joint portion is polished so as to be smoothly connected after the adhesive is dried.

  The heater 60 is a planar heater and is attached to the inner surface of the roller 10 to heat the roller 10 from the inside. Thereby, when the roller 10 is applied to the skin 3, it can suppress giving a user unpleasant coldness. The heater 60 is a film heater in the present embodiment, and includes a flexible film 61 and a conductive member (not shown) attached to the film 61 and generating heat by power feeding.

  The film 61 has flexibility. “Flexibility” refers to the property of being elastically deformable along the inner surface of the roller 10. The conductive member is, for example, a conductive resin, and has flexibility like the film 61. Therefore, the heater 60 can be elastically deformed (curved) along the inner surface of the roller 10 having a three-dimensional curved surface shape, and the gap between the heater 60 and the inner surface of the roller 10 can be reduced. Can be contacted. Thereby, the heat from the conductive member can be efficiently transmitted to the roller 10.

  8 and 9 are diagrams showing the heater 60. FIG. 8 is a view showing the shape of the heater 60 before being placed in the roller 10, and FIG. 9 is a view showing the shape of the heater 60 when being placed in the roller 10.

  When the heater 60 is elastically deformed along the inner surface of the roller 10, no gap is formed between the heater 60 and the inner surface of the roller 10. In other words, the heater 60 is formed in a shape that does not cause wrinkles. Is done. In the present embodiment, the heaters 60 are formed radially. Specifically, the heater 60 includes a center portion 62 and a plurality (six in this case) of extending portions 63 extending radially from the center portion 62. The heater 60 is disposed in the roller 10 so that the rotation axis X of the roller 10 passes through the approximate center of the center portion 62. If the contact area between the heater 60 and the inner surface of the roller 10 is increased, the contact area between the conductive member and the inner surface of the roller 10 can be increased by spreading the conductive member correspondingly. Can be conveyed to the roller 10. Therefore, the size of the central portion 62 and the number and width of the extending portions 63 are determined by simulation and experiment so that the contact area between them and the inner surface of the roller 10 is as large as possible.

  FIG. 10 shows another example of the heater 60. FIG. 10 corresponds to FIG. In this example, the extending portion includes a base portion 63 a connected to the center portion 62 and a widened portion 63 b connected to the end portion of the base portion 63 a on the opposite side of the center portion 62. The base part 63a is formed to have a constant width, and the widened part 63b is formed to increase in width as the distance from the center part 62 and the base part 63a increases. In particular, the widened portion 63b is arranged so that the adjacent widened portions 63b do not overlap each other when the heater 60 of FIG. 10 is disposed in the roller 10 so that the rotation axis X of the roller 10 passes through the approximate center of the central portion 62. It is formed. According to the heater 60 of FIG. 10, the contact area with the inner surface of the roller 10 can be made wider than that of the heater 60 of FIGS.

  Returning to FIG. 7, a protrusion 12 a that protrudes into the roller 10 is provided on the inner surface of the cover portion 12 of the roller 10. The tip of the extension part 63 of the heater 60 (that is, the end opposite to the center part 62) contacts the protrusion 12a. Thereby, it can suppress that the heater 60 arrange | positioned in the roller 10 in the elastically deformed state returns to planar shape by the restoring force, As a result, a clearance gap arises between the heater 60 and the inner surface of the roller 10. Can be suppressed. In FIG. 7, the protrusion 12 a is provided in an annular shape so as to surround the rotation axis X. However, the protrusion 12 a is not limited to this, and may be provided only at a portion that contacts the distal end portion 63 c of the extending portion 63, for example.

  FIGS. 11-14 is a perspective view which shows the slip ring mechanism 70 and its periphery. 12, the display of the shaft 14 is omitted, the display of the lid 16 is further omitted in FIG. 13, and the display of the wiring housing 18 is further omitted in FIG. FIG. 15 is a sectional view of the shaft 14. With reference to FIGS. 11 to 14 in addition to FIG. 7, a configuration for supplying electric power to the roller 10 which is a rotating body will be described.

  The slip ring mechanism 70 includes a first conductive ring 71a to a fourth conductive ring 71d, which are collectively referred to as a conductive ring 71, and a first slider 72a to a fourth slider 72d, which are collectively referred to as a slider 72, and are insulated. A ring 73. The conductive ring 71 is a ring-shaped member having conductivity. The slider 72 is a member having conductivity.

  The first slider 72a to the fourth slider 72d are in pressure contact with the outer peripheral surfaces of the first conductive ring 71a to the fourth conductive ring 71d, respectively. The slider 72 according to the present embodiment is an elastic body and is pressed against the outer peripheral surface of the conductive ring 71 by its own elasticity. Therefore, the conductive ring 71 and the slider 72 corresponding to the conductive ring 71 are also in sliding contact with each other when the roller 10 and the shaft 14 rotate relative to each other. Further, the slider 72 has a plurality of branches at the tip that contacts the outer peripheral surface of the conductive ring 71. Here, for example, when the beauty roller 1 is used, the conductive ring 71 and the slider 72 may be relatively displaced so as to be pressed against each other. When the tip of the slider 72 is deformed by this relative displacement, the connection state between the slider 72 and the conductive ring 71 may not be maintained. In the present embodiment, the tip of the slider 72 is branched, and the connection state with the conductive ring 71 is maintained unless all the branched tip portions are deformed. The possibility that the connection state cannot be maintained can be reduced. The slider 72 may be pressed against the outer peripheral surface of the conductive ring 71 by being biased by biasing means such as a spring. The conductive ring 71 and the slider 72 may be made of any material as long as they have conductivity, but those having high wear resistance and low electrical resistance are preferable.

  The insulating ring 73 is a ring-shaped insulator, and surrounds the shaft 14 and is fixed to the shaft 14. The insulating ring 73 includes a small diameter portion 73a and a large diameter portion 73b having a larger diameter than the small diameter portion 73a. A conductive ring 71 is fixed to the outer periphery of the small diameter portion 73a. That is, the insulating ring 73 is fixed to the shaft 14, and the conductive ring 71 is fixed to the insulating ring 73. Therefore, the conductive ring 71 rotates integrally with the shaft 14. The small-diameter portion 73a protrudes between the adjacent conductive rings 71 more radially outward than the conductive rings 71 to prevent the conductive rings 71 from contacting each other, and the slider 72 corresponds to the corresponding conductive ring 71 (for example, the first sliding ring). The moving element 72a prevents contact with anything other than the first conductive ring 71a).

Each of the first fixed side wiring member 32a, the second fixed side wiring member 32b, the third fixed side wiring member 32c, and the fourth fixed side wiring member 32d has a power supply portion (not shown in FIGS. 7 and 11 to 15). And the other end of the first slider 72a through a wiring (not shown) mounted on the substrate 44,
The second slider 72b, the third slider 72c, and the fourth slider 72d are electrically connected.

  The movable side wiring member 34 is formed in an elongated plate shape. Each of the first movable side wiring member 34a, the second movable side wiring member 34b, the third movable side wiring member 34c, and the fourth movable side wiring member 34d has a first conductive ring 71a, a second conductive ring 71b, and a third one at one end. It is connected to the conductive ring 71 c and the fourth conductive ring 71 d and extends into the roller 10 through the hollow shaft 14. The movable wiring member 34 rotates integrally with the shaft 14 and the roller 10.

Summary,
(1) The first fixed-side wiring member 32a, the corresponding wiring mounted on the substrate 44, the first slider 72a, the first conductive ring 71a, and the first movable-side wiring member 34a are electrically connected in this order,
(2) The second fixed side wiring member 32b, the corresponding wiring mounted on the substrate 44, the second slider 72b, the second conductive ring 71b, and the second movable side wiring member 34b are electrically connected in this order,
(3) The third fixed side wiring member 32c, the corresponding wiring mounted on the substrate 44, the third slider 72c, the third conductive ring 71c, and the third movable side wiring member 34c are electrically connected in this order,
(4) The fourth fixed side wiring member 32d, the corresponding wiring mounted on the substrate 44, the fourth slider 72d, the fourth conductive ring 71d, and the fourth movable side wiring member 34d are electrically connected in this order. .
The conductive ring 71 and the slider 72 corresponding to the conductive ring 71 are in sliding contact with each other when the roller 10 and the shaft 14 rotate relative to each other, and the electrical connection state thereof is maintained. . Therefore, even when the roller 10 is rotating, the roller from the handle 20 which is a fixed body through the fixed side wiring member 32, the wiring mounted on the substrate 44, the slider 72, and the conductive ring 71 movable side wiring member 34. 10 can be supplied with power.

  The shaft 14 is provided with a non-conductive wiring housing 18. Each of the movable side wiring members 34 is accommodated in a groove 18 a formed in the wiring housing 18. Each groove 18 a is closed by a non-conductive plate-like lid 16. That is, the movable side wiring members 34 are isolated from each other. Accordingly, even if the movable side wiring member 34 vibrates due to an impact applied to the beauty roller 1, it is possible to prevent the movable side wiring members 34 from coming into contact with each other and causing a short circuit. Moreover, since the movable side wiring member 34 can move only in the groove 18a even if vibration is applied, that is, it is restricted so as not to move greatly, it is prevented from being broken by moving greatly.

  In the present embodiment, the first fixed-side wiring member 32a and the first movable-side wiring member 34a are connected to the heater 60 and a thermistor (not shown) as a protection circuit for the first fixed-side wiring member 32a and the first movable-side wiring member 34a. Used as a line to supply. Although not shown, the second fixed side wiring member 32b and the second movable side wiring member 34b are connected to the cover part 12 and are used as lines for supplying a weak current called microcurrent to the human body. Specifically, it is used as a part of a current path including the power supply unit, the roller 10, the human body, and the handle 20. Microcurrent is a very weak current of, for example, μA. By flowing it through the skin and stimulating the cells, sleeping cells are activated, lymph flow is improved, and blood circulation is promoted. Or increase your metabolism.

  The third fixed-side wiring member 32c and the third movable-side wiring member 34c are used as a ground line that is a common return line. The fourth fixed side wiring member 32d and the fourth movable side wiring member 34d are connected to a thermistor (not shown), and are used as lines through which signals from the thermistor flow.

  Here, generally, when a current flows through the wiring, a magnetic field is generated around the current. The magnetic field is large near the wiring and decreases with distance from the wiring. In addition, when the magnetic field changes, an induced current can flow through the wiring in the range covered by the magnetic field. Accordingly, when a current flows through the first movable side wiring member 34a and the second movable side wiring member 34b, a magnetic field is generated, and if the fourth movable side wiring member 34d exists within the range covered by the magnetic field, the magnetic field changes. An induced current can flow through the fourth movable-side wiring member 34d. This becomes noise for the signal from the thermistor.

  On the other hand, in the present embodiment, the distance between the fourth movable side wiring member 34d and the first movable side wiring member 34a or the second movable side wiring member 34b is set to be the third movable side wiring member 34c that is a ground line therebetween. It is relatively far away by arranging. Thereby, it is possible to prevent an induced current from flowing through the fourth movable side wiring member 34d due to a current flowing through the first movable side wiring member 34a and the second movable side wiring member 34b. That is, noise with respect to the signal from the thermistor can be reduced. Thereby, accurate temperature management becomes possible.

  FIG. 16 is a block diagram showing the function and configuration of the beauty roller 1. The beauty roller 1 further includes a power supply unit 30 and a control unit 80. The power supply unit 30 is electrically connected to the control unit and supplies power. The power supply unit 30 may be a secondary battery such as a lithium ion battery or a replaceable primary battery.

  The control unit 80 includes a first communication unit 81, a second communication unit 82, and a data processing unit 84. Each block of the control unit 80 can be realized in hardware by an element such as a CPU of a computer or a mechanical device, and is realized in software by a computer program or the like. Draw functional blocks. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

  The 1st communication part 81 communicates with information processing terminals (for example, a smart phone, a tablet, etc.) by 1st near field communication, for example, Wi-Fi (trademark). The second communication unit 82 communicates with the information processing terminal by second short-range wireless communication different from the first short-range wireless communication, for example, Bluetooth (registered trademark).

  The data processing unit 84 includes a display control unit 90, an energization control unit 92, an image processing unit 94, and a transmission / reception control unit 96.

  The display control unit 90 displays various information on the display unit 28. The display control unit 90 displays various operation screens on the display unit 28, for example.

  The energization control unit 92 supplies power to the heater 60 from the power supply unit 30 to heat the roller 60 to heat the roller 10 in accordance with a user operation via the display unit 28, or heats the roller 10, or from the power supply unit 30 to the heater 60. The supply of the electric power is stopped and the heat generation of the heater 60 is stopped. At this time, the energization control unit 92 may change the lighting mode of the display lamp 26 according to the heating of the roller 10. For example, when the supply of power to the heater 60 is started, the display lamp 26a closest to the roller 10 is turned on, the number of display lamps 26a to be turned on is increased as heating progresses, and a large display is displayed when the roller 10 is heated to a predetermined temperature. All the display lamps 26 including the lamp 26b may be turned on. In this case, the user can grasp the heating state of the roller 10 at a glance.

  Further, the energization control unit 92 may change the electric power supplied from the power supply unit 30 to the heater 60 in accordance with a user operation to heat the roller 10 to a relatively high temperature or low temperature. In this case, the energization control unit 92 may change the color that causes the display lamp 26 to shine when the roller 10 is heated to a comparatively low temperature and when the roller 10 is heated to a relatively high temperature. Thereby, the user can grasp at a glance whether the heating is performed at a low temperature or at a high temperature.

  Further, the energization control unit 92 supplies the microcurrent to the human body from the power supply unit 30 via the roller 10 or stops the supply in accordance with a user operation via the display unit 28. The energization control unit 92 may turn on the display lamp 26 while supplying the microcurrent to the human body. Thereby, the user can realize that the microcurrent is flowing in the body.

  Further, the energization control unit 92 supplies power from the power supply unit 30 to the imaging unit 40 in accordance with a user operation via the display unit 28 and causes the imaging unit 40 to perform imaging, or from the power supply unit 30 to the imaging unit 40. The power supply is stopped and the imaging by the imaging unit 40 is stopped. The energization control unit 92 causes the imaging unit 40 to take an image only when there is an imaging instruction and the roller 10 is rotating, and does not cause the imaging unit 40 to take an image when the roller 10 is not rotating even if there is an imaging instruction. You may control so. Thereby, it can suppress that the imaging part 40 is used for a sneak shot.

  The image processing unit 94 performs signal processing such as A / D conversion and noise removal on the image signal generated by the imaging unit 40. Further, the image processing unit 94 performs predetermined compression processing, and generates image data in, for example, JPEG (Joint Photographic Coding Experts Group) format.

  The transmission / reception control unit 96 controls transmission / reception of data. The transmission / reception control unit 96 transmits image data based on the image signal generated by the imaging unit 40 to the information processing terminal via the first communication unit 81, and transmits / receives other data via the second communication unit 82. By using the first communication unit 81 only for transmission of image data, it is possible to prevent a delay in transmission of image data.

  Next, the effect produced by the beauty roller 1 configured as described above will be described. According to the beauty roller 1, the wiring member for supplying the power from the power supply unit 30 to the roller 10 passes through the shaft 14. Thereby, the freedom degree of design of the beauty roller 1 improves. Further, since the wiring member rotates near the central axis of the shaft 14 as compared with the case where the wiring member is provided outside the shaft 14, the wiring member is rotated when the wiring member rotates with the rotation of the roller 10 and the shaft 14. The load due to the centrifugal force is suppressed. As a result, for example, it is possible to prevent the connection portion between the wiring member and the conductive ring 71 from being damaged. Further, the wiring member can be protected by the shaft 14.

  Further, according to the beauty roller 1, the roller 10 and the shaft 14 are rotated together, and the slip ring mechanism 70 is disposed in the handle 20. Thereby, the space of the roller 10 can be used effectively.

  The present invention has been described based on the embodiments.

For example, the shaft 14 may be fixed to the handle 20, and the roller 10 may be rotated with respect to the shaft 14 and thus the handle 20. In this case, the slip ring mechanism 70 may be disposed in the roller 10 and the fixed side wiring member 32 may be passed through the shaft 14. Further, for example, the first shaft may be fixed to the handle 20, the second shaft may be fixed to the roller 10, and the second shaft and thus the roller 10 may be rotated with respect to the first shaft and thus the handle 20. In this case, for example, the connection portion between the first shaft and the second shaft has a double cylinder structure, the slip ring mechanism 70 is disposed between them, and the fixed side wiring member 32 is passed through the first shaft, The movable side wiring member 34 may be passed through the second shaft.

(Modification 4)
Although not particularly mentioned in the embodiment, the beauty roller 1 may function as an ion introducer. Although not particularly limited, in this modification, the second fixed-side wiring member 32b and the second movable-side wiring member 34b for supplying a microcurrent are also used for supplying a weak current for ion introduction. In this case, the beauty roller 1 can be used by switching between the function of supplying a microcurrent and the function of an ion introducer.

  As the waveform of the weak current for ion introduction, various modes such as a direct current in which the current and voltage are constant, a pulse current, and a sine wave alternating current can be adopted, and a plurality of these various waveforms are combined. It is also possible. Here, a case where a weak current having a waveform shown in FIG. 18 is supplied will be described.

  The energization control unit 92 controls the potential difference between the two electrodes so that the roller 10 (first electrode) has a low potential with respect to the handle 20 (second electrode), and generates a plurality of pulse voltages between the two electrodes. Apply once. Thereby, a negative pulse current like a waveform F1 shown in FIG. 18 flows from the roller 10 to the skin 3 a plurality of times. As a result, the lotion applied to the skin 3 can penetrate more into the skin 3. Note that the user may be able to specify the magnitude of the pulse voltage applied between the electrodes by the energization control unit 92 and the weak current flowing through the human body via the display unit 28.

  The energization control unit 92 applies a pulse voltage once between the electrodes while controlling the potential difference between the electrodes so that the roller 10 has a high potential with respect to the handle 20. As a result, a positive pulse current like a waveform F <b> 2 shown in FIG. 18 flows from the roller 10 to the skin 3. It is possible to neutralize the bias of charge generated on the skin 3 in the ion introduction step.

Any of the following functions may be performed in accordance with a user operation via the display unit 28.
・ Microcurrent ・ Microcurrent and heater (low temperature)
・ Microcurrent and heater (high temperature)
・ Ion introduction, ion introduction and heater (low temperature)
・ Ion introduction and heater (high temperature)

  According to this modification, since the beauty roller 1 can also function as an ion introducer, the roller 10 is applied to the skin 3 while rolling it against the skin 3 to pick up or spread the skin 3. The beauty liquid can penetrate into the skin 3. Further, since the wiring member for supplying the microcurrent can be used for supplying a weak current for ion introduction, a dedicated wiring member for ion introduction becomes unnecessary, and the manufacturing cost of the beauty roller 1 can be suppressed.

(Modification 5)
FIG. 19 is a schematic diagram illustrating a schematic configuration of a wireless power feeding system 100 including the beauty roller 1. The wireless power feeding system 100 includes a power feeding device 110 and a beauty roller 1 as a power receiving device.

  The power feeding device 110 includes a first permanent magnet 112, a first coil 114, a power source 116, and a control unit 118. The power supply device 110 supplies power to the beauty roller 1 wirelessly. The first coil 114 is wound around the first permanent magnet 112. The control unit 118 applies an AC voltage or a DC voltage from the power supply 116 to the first coil 114.

  The beauty roller 1 further includes a second permanent magnet 122, a second coil 124, and a detection unit 126. The beauty roller 1 receives power from the power supply device 110 wirelessly. The second coil 124 is wound around the second permanent magnet 122. The detection unit 126 detects the current or voltage of the second coil 124.

An operation of the wireless power feeding system 100 will be described.
The south pole of the second permanent magnet 122 of the beauty roller 1 and the north pole of the first permanent magnet 112 of the power supply device 110 are adjacent to each other, and the central axis of the second coil 124 of the beauty roller 1 and the first pole of the power supply device 110. The beauty roller 1 is arranged with respect to the power feeding device 110 so that the central axis of the second coil 124 is arranged substantially coaxially. The control unit 118 applies a voltage from the power source 116 to the first coil 114 in accordance with a user operation via an operation unit (not shown) of the power supply apparatus 110. Thereby, the magnetic field generated in the first coil 114 fluctuates, an electromotive force is generated in the second coil 124 by electromagnetic induction, and power is supplied from the first coil 114 to the second coil 124 wirelessly. . The supplied power is stored in the power supply unit 30.

  The detection unit 126 detects the current or voltage of the second coil 124 during wireless power feeding. The detection value by the detection unit 126 is transmitted to the control unit 118 of the power supply apparatus 110 at a predetermined cycle. The control unit 118 stops the application of voltage from the power supply 116 to the first coil 114 when the detection value by the detection unit 126 is out of the range of the assumed value. That is, wireless power feeding is stopped. In addition, as a case where the detection value by the detection unit 126 deviates from the range of the assumed value, for example, the beauty roller during wireless power feeding is a counterfeit product, or the magnetic force is amplified between the beauty roller 1 and the power feeding device 110, for example. There are cases where there is something to be done. In this case, the control unit 118 detects on the display unit (not shown) of the power supply apparatus 110 that, for example, the current or voltage outside the range of the assumed value has been detected, so that the wireless power supply is stopped, or the beauty roller is a counterfeit product. You may display that there is a possibility that it is.

  According to this modification, by preventing power supply to counterfeit goods, it is possible to reduce the willingness to purchase counterfeit goods and consequently prevent counterfeit goods from spreading. In addition, when current or voltage exceeding the range of the assumed value is supplied to the beauty roller 1, there is a possibility that the beauty roller 1 may malfunction, and this can be prevented.

  Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment generated by the combination has the effects of the combined embodiment and the modified examples.
