[0010] The beauty device 1 of this embodiment is a beauty device having a contact surface that comes into contact with the skin, and includes a main body, a base supported by the main body, a flexible contact member supported by the base and forming the contact surface, and an electrode that detects cosmetics on the surface of the skin that comes into contact with the contact surface, the electrode slidably passing through the base and engaging with the contact member so that the tip of the electrode protrudes from the contact surface.

[0011] As shown in FIG. 1, the beauty device 1 is configured as part of a beauty system 100. In the beauty system 100, the beauty device 1 is connected to a mobile device 2 so as to be able to communicate wirelessly or via a wired connection. In this specification, a beauty device refers to a device used for beauty purposes, such as substituting for the application of cosmetics, without affecting the structure or function of the human body, including the skin. The beauty device 1 is an example of a beauty device according to this embodiment.

[0012] The beauty device 1 constitutes an applicator that a user U uses to apply cosmetics or for application actions (see FIGS. 1 and 2). The beauty device 1 includes a main body 10, a handle 20, a contact member 30, a cosmetic sensor 40, contacts 50, a base 60, suspenders 70, and a frame 80 (see FIGS. 2 to 9).

[0013] In this specification, the term "cosmetics" is not particularly limited and includes, for example, skin care cosmetics such as lotion, serum, emulsion, cream, etc. (also called basic cosmetics), and makeup cosmetics such as foundation, blush, lipstick, gloss, eyebrow pencil, eyeliner, eye shadow, mascara, nail polish, perfume, etc. Furthermore, "application" refers to the act of painting (or daubing) cosmetics.

[0014] The main body 10 includes a substrate 11, an acceleration sensor 12, a pressure sensor 13, a vibration motor 14, a communication module 15, and a locking portion 16 (see FIGS. 2 to 8).

[0015] The substrate 11 is provided with a computer (not shown). The computer has a central processing unit (CPU), a memory, an information input unit, and an information output unit (not shown). The CPU has a control unit and can control the beauty device 1. Specifically, the CPU controls the acceleration sensor 12, the pressure sensor 13, the vibration motor 14, and the communication module 15, and performs various processes such as calculation, control, storage, transfer, input, output, transmission, and reception of information. The control unit may be configured separately from the CPU.

[0016] The memory constitutes a temporary storage device that stores information to be calculated when the CPU executes processing. The information input unit receives information from the mobile terminal 2 and inputs the information to the beauty device 1. The information output unit outputs information such as detection results obtained by the beauty device 1. The information output from the information output unit is transmitted to the mobile terminal 2.

[0017] The acceleration sensor 12 is an element or device supported by the main body 10 and detects the acceleration generated in the beauty device 1 during the cosmetic application operation. For example, the application speed of the cosmetic during the application operation using the beauty device 1 can be measured from the acceleration detected by the acceleration sensor 12.

[0018] The pressure sensor 13 is an element or device supported by the main body 10 and detects the pressure generated in the beauty device 1 during the cosmetic application operation. The pressure sensor 13 detects the contact pressure (or pressing force) P when the contact surface 31 of the contact member 30, which will be described later, comes into contact with the skin (see FIGS. 8, 9, and 19). In this specification, skin refers to the skin of a person's face, neck, arms, legs, etc. The contact pressure refers to the pressure (or pressing force) generated on the contact surface 31 when the contact surface 31 comes into contact with the skin.

[0019] The vibration motor 14 is an element or device that has the function of notifying the user U of the sensation of operating the beauty device 1 or information from the mobile terminal 2 by vibration or vibration sound. The communication module 15 transmits information obtained by the beauty device 1 to the mobile terminal 2 and receives information transmitted from the mobile terminal 2.

[0020] The locking portion 16 includes sliders 16A and 16B. The locking portion 16 locks a contact member 30 (described later) to the main body 10 by the sliders 16A and 16B so that the contact member 30 can slide in the height direction (Z direction) relative to the main body 10 (see FIGS. 2, 3, 4, 7, 8, 9, and 19).

[0021] In the beauty device 1, the configurations of the substrate 11, acceleration sensor 12, pressure sensor 13, vibration motor 14, and communication module 15 are not limited. For example, the pressure sensor 13 may be of any type and material. In addition, the beauty device 1 may include auxiliary devices such as a hard disk drive (HDD) and a modular jack (not shown).

[0022] The handle 20 constitutes a grip (or a handle) for applying or performing the application action of the cosmetic. The handle 20 includes a knob 21 and a joint 22. The knob 21 constitutes the part of the handle 20 that the user U grips (or holds). The joint 22 constitutes the part that connects the knob 21 to the main body 10.

[0023] The knob 21 is configured by screwing an upper portion 21A and a lower portion 21B together with fixing portions 23 (23A, 23B). The knob 21 is provided with a push-button switch 24. The switch 24 is connected to the substrate 11 via a fixing member (not shown) (e.g., a harness member, a flexible member, etc.). By operating the switch 24, the user U can switch the beauty device 1 on and off or change the operating state of the beauty device 1.

[0024] The knob 21 also has a built-in LED lamp 26 (see FIGS. 6 and 8). The LED lamp 26 lights up or flashes to indicate the operating state of the beauty device 1. In the present disclosure, the upper portion 21A of the knob 21 is transparent or translucent, so that the LED lamp 26 can be seen lit or flashing from outside the knob 21.

[0025] The handle 20 houses a battery 25 that constitutes the power source for the beauty device 1 (see FIG. 8). The battery 25 is controlled by the above-mentioned CPU and supplies power to each of the elements 11 to 15, 40 of the beauty device 1. The battery 25 is housed in the handle 20 so as to be replaceable by opening and closing the above-mentioned fixing portion 23. In the present disclosure, a portion of the battery 25 is also housed in the main body 10, but the entire battery 25 may also be housed in the main body 10.

[0026] The contact member 30 has an end 37 locked by the locking portion 16 (slider 16A, 16B) so as to be slidable in the height direction (Z direction) relative to the main body 10 (see Figures 2, 3, 4, and 7). The contact member 30 is flexible. Here, flexibility refers to the property of being easily elastically deformed. The material of the contact member 30 is not limited, but is preferably an elastic material, such as elastomer or rubber, with silicone rubber being preferred.

[0027] As shown in Figures 11 and 12, the contact member 30 has a circular outline in a plan view. The shape of the contact member is not limited to this, and the outline in a plan view may be rectangular, elliptical, or the like. The contact member 30 is supported by a base 60, which will be described later. The contact member 30 is provided with a contact surface 31, recesses 32 and 33, through-holes 34 and 35, and protrusions 36 (see Figures 8 to 12). The contact member 30 is an example of a contact member that constitutes the beauty device according to this embodiment.

[0028] The contact surface 31 is a part of the contact member 30 that comes into contact with the skin. Specifically, the contact surface 31 constitutes the surface that is brought into contact with the skin (or the skin) of the user U when applying or performing an application operation of the cosmetic material. The contact surface 31 is an example of a contact surface formed on a contact member that constitutes the beauty device according to this embodiment.

[0029] Tips (flanges) 42B, 43B of electrodes 42, 43 of cosmetic sensor 40, which will be described later, are fitted into recesses 32, 33 (see FIGS. 8 to 10 and 12). Openings 32B, 33B that communicate with through-holes 34, 35 that penetrate contact member 30 in the thickness direction (Z direction) are provided in bottoms 32A, 33A of recesses 32, 33. Peripheral walls 34A, 35A of through-holes 34, 35 face side surfaces 42F, 43F of bases 42A, 43A of electrodes 42, 43 of cosmetic sensor 40 (see FIGS. 8 to 13).

[0030] The protrusion 36 is formed as a circular protrusion, and together with the peripheral walls 34A, 35A of the through holes 34, 35, supports the pedestal 60, which will be described later, in the thickness direction (Z direction) of the contact member 30 (see FIGS. 8 to 11). A crease (not shown) corresponding to the periphery of the contact surface 31 is provided between the protrusion 36 and the end portion 37 (see FIGS. 8, 9, and 11).

[0031] Cosmetic sensor 40 is controlled by a CPU and detects cosmetics on the surface of the skin with which contact surface 31 of contact member 30 comes into contact (see FIGS. 8, 9, 13 to 16). Cosmetic sensor 40 includes a sensor main body 41 housed in a recess 84 of frame 80, which will be described later, electrodes 42 and 43 exposed on contact surface 31 to detect cosmetics on the surface of the skin with which contact surface 31 comes into contact, and lead wires 44 and 45 that electrically connect electrodes 42 and 43 to sensor main body 41 (see FIGS. 8 and 9).

[0032] Here, the cosmetic sensor is a sensor capable of detecting cosmetic ingredients. The detected cosmetic indicates the amount or concentration of ingredients such as water or oil contained in the cosmetic. The electrodes constitute terminals of the cosmetic sensor that detect the cosmetic ingredients. In this embodiment, a system is adopted in which the cosmetic sensor detects the moisture content of the cosmetic. However, the detection system of the cosmetic sensor is not limited to this system, and a detection system using an optical sensor such as a photoreflector may also be adopted.

[0033] The electrodes 42, 43 are exposed on the contact surface 31. The electrodes 42, 43 have cylindrical bases 42A, 43A and extending portions at one end (tips 42B, 43B) of the bases 42A, 43A in the longitudinal direction (Z direction) of the bases 42A, 43A that extend in the radial direction (R direction) of the bases 42A, 43A (see FIG. 14 ). The tips (extending portions) 42B, 43B form flanges that are fitted into the recesses 32, 33 of the contact member 30.

[0034] Tips 42B, 43B of electrodes 42, 43 have end faces 42E, 43E that protrude in the height direction (Z direction) from contact surface 31 (see FIGS. 8 to 10, 13, and 15). Tips 42B, 43B may have any shape, but are preferably curved. Here, a curved surface refers to a portion of a spherical surface.

[0035] Holes 42C and 43C are formed in bottom surfaces 42G and 43G of bases 42A and 43A. Lead wires 44 and 45 are fitted into holes 42C and 43C. Grooves 42D and 43D are formed in side surfaces 42F and 43F of bases 42A and 43A. O-rings 46 and 47 are fitted into grooves 42D and 43D (see FIGS. 8 to 10, 13, and 14). The material of the O-ring is not particularly limited, but is preferably a flexible member, and for example, elastomer, rubber, or the like can be used.

[0036] The contactor 50 is a member that comes into contact with the pressure sensor 13 and transmits the contact pressure P generated on the contact surface 31 of the contact member 30 to the pressure sensor 13 (see FIGS. 8, 9, and 19). The contactor 50 may be provided integrally with the contact member 30, or may be provided separately from the contact member 30 on a member having a contact surface. The contactor 50 is supported on a frame 80 of the main body 10 via a base 60 and suspenders 70, which will be described later.

[0037] The form of the contactor 50 is not limited, but it is preferable that the contactor 50 has flexibility. The material of the contactor 50 is not limited, and for example, elastomer, rubber, etc. can be used, and among these, silicone rubber is preferable.

[0038] The contact 50 includes a base 51 and a plurality of protrusions 52. The shape of the base 51 is not limited, and in this embodiment, the base 51 has a disk shape. A surface 51A of the base 51 is provided with a plurality of protrusions 52 (see FIGS. 8 and 9).

[0039] The base 51 of the contact 50 is supported by a pedestal 60, which will be described later. A side surface 51C of the base 51 faces a side surface 62A of a recess 62, which will be described later, of the pedestal 60. A circular fitting groove 53, which fits into a fitting protrusion 63 of the pedestal 60, is formed on a back surface 51B of the base 51. The base 51 is fixed to the pedestal 60 by fitting the fitting groove 53 into the fitting protrusion 63 of the pedestal 60 (see FIGS. 8 and 9).

[0040] The plurality of protrusions 52 are formed independently on the surface 51A of the base 51. The base ends 52A of the protrusions 52 are connected to the base 51. The number of protrusions 52 is not limited and can be two or more, preferably five or more, and more preferably seven or more. In this embodiment, nine protrusions 52 are provided on the surface 51A of the base 51 (see FIGS. 8 and 9).

[0041] The dimensions of the protrusion 52 are not limited. For example, the length in the left-right direction (X direction) or the front-rear direction (Y direction) can be 1 mm to 15 mm, preferably 2 mm to 10 mm, and more preferably 3 mm to 5 mm. The length in the height direction (Z direction) can be 0.5 mm to 10 mm, preferably 1 mm to 8 mm, and more preferably 2 mm to 5 mm.

[0042] The shape of the protrusions 52 is arbitrary, but it is preferable that the protrusions 52 have a shape that tapers toward the pressure sensor 13. In this specification, a shape that tapers toward the pressure sensor 13 refers to a shape in which each protrusion 52 of the contactor 50 extends in a tapered manner toward the pressure sensor 13 when the contactor 50 faces the pressure sensor 13. Specifically, the side end 52B of the protrusion 52 has a conical shape that tapers from the base end 52A toward the tip end 52C (see FIGS. 8 and 9).

[0043] The protrusion 52 is provided so as to be able to come into contact with the pressure sensor 13. Specifically, when the contact surface 31 of the contact member 30 is not in contact with the skin, the contactor 50 is arranged so that the tip 52C of the protrusion 52 is spaced a given distance from the pressure sensor 13 (see FIGS. 8 and 9). Here, "spaced a given distance" means that the contactor 50 is arranged with respect to the pressure sensor 13 with a predetermined distance between the tip 52C of the protrusion 52 and the pressure sensor 13.

[0044] The base 60 supports the contactor 50 while fixing the contact member 30. The base 60 is provided so as to be slidable in the height direction (Z direction) relative to the main body 10 together with the contact surface 31 of the contact member 30 (see FIGS. 8, 9, and 19). The shape of the base 60 is not limited, and in this embodiment, it has a disk shape.

[0045] The base 60 has a base 61, a recess 62, a pair of through holes 64, 65, and a circular side wall 66. The recess 62 accommodates the contactor 50 such that the side surface 51C of the contactor 50 faces the side surface 62A. The fitting protrusion 63 is formed on the bottom surface 62B of the recess 62 and fits into the fitting groove 53 of the contactor 50 (see FIGS. 8, 9, 17, and 18). The electrodes 42, 43 of the cosmetic sensor 40 are slidably inserted through the pair of through holes 64, 65. The circular side wall 66 fits into the other end 73 of the suspender 70 (described later) (see FIGS. 8 and 9).

[0046] In the base 60, a pair of through-holes 64, 65 are formed by cylindrical side surfaces 64A, 65A. Parts of the bases 42A, 43A of the electrodes 42, 43 are inserted into the side surfaces 64A, 65A of the through-holes 64, 65. O-rings 46, 47 fitted in the grooves 42D, 43D of the bases 42A, 43A slide in contact with the side surfaces 64A, 65A. This allows the electrodes 42, 43 to slide liquid-tightly relative to the base 60 (see FIGS. 8 to 10, 19, and 20).

[0047] The form of the base 60 is not limited, but it is preferable that it has rigidity. The material of the contactor 50 is not limited, and for example, insulating resin, ceramic, etc. can be used, and among these, insulating resin is preferable. Furthermore, among insulating resins, polyacetal (polyoxymethylene (POM)) is more preferable from the viewpoint of imparting chemical resistance, abrasion resistance, etc. to the base.

[0048] The suspenders 70 support the contacts 50 on the main body 10. The suspenders 70 are made of a flexible material. Here, a flexible material refers to a material that is easily elastically deformed. The material of the flexible material that makes up the suspenders 70 is not limited, and can be, for example, elastomer, rubber, etc., with rubber having a rubber hardness of approximately 30 being preferred. The suspenders 70 are an example of a flexible material that makes up a part of the beauty device according to this embodiment.

[0049] Suspenders 70 have a base 71, one end 72, and the other end 73. The form of the flexible member that makes up suspenders 70 is not particularly limited, but it is preferable that base 71 be formed as a pleated tubular body (see Figures 8 and 9). Here, a tubular body with pleated side walls refers to a cylindrical shape in which the side surface of the cylinder extends in an accordion-like (or stepped) manner from one bottom surface to the other bottom surface (see Figures 8 and 9).

[0050] The spacing between the bases 71 of the cylindrical bodies constituting the suspenders 70 in the radial direction (X direction) becomes shorter from the main body 10 side toward the contactor 50 side (see FIGS. 8 and 9). Here, the spacing between the bases 71 in the radial direction (R direction) of the cylindrical bodies 70 refers to the distance between the bases 71 facing each other in the radial direction (X direction) of the cylindrical bodies 70. Furthermore, the spacing between the bases 71 becoming shorter from the main body 10 side toward the contactor 50 side means that the cylindrical bodies 70 become tapered from the main body 10 side toward the contact member 30 side (see FIGS. 8 and 9).

[0051] The suspenders 70 are arranged so that the contacts 50 are suspended from the main body 10 via the suspenders 70. Here, "suspended" means that the suspenders 70 are suspended or hung from the main body 10. In the present disclosure, one end 72 of the suspenders 70 is fitted into an end (fitting groove) 85 of a circular frame 80, which will be described later, and the other end 73 of the suspenders 70 is fitted into the side wall 66 of the base 60 (see FIGS. 8 and 9).

[0052] As a result, the base 60 is supported on the main body 10 by the suspenders 70 while supporting the contacts 50. Specifically, the contacts 50 are supported via the suspenders 70 made of a flexible material so as to be slidable in the height direction (Z direction) relative to the main body 10 together with the contact members 30 and the base 60 (see FIGS. 8, 9, and 19).

[0053] The frame 80 is fixed to the main body 10 (see FIG. 8). The shape of the frame 80 is not limited, and in this disclosure, the frame 80 has a disk shape. The frame 80 has a base 81, a clearance 82, a recess 83, a recess 84, and an end 85.

[0054] The base 81 forms the framework of the frame 80. The clearance 82 is provided approximately in the center of the base 81 and contributes to reducing the weight of the beauty device 1 (main body 10). The recess 83 is formed on the side of the base 81 opposite to the side where the clearance 82 is provided and accommodates the pressure sensor 13. The recess 84 is formed around the recess 83 and accommodates the cosmetic sensor 40. The end 85 forms a fitting groove and fits one end 72 of the suspender 70 (see Figures 8 and 9).

[0055] The form of the frame 80 is not limited, but it is preferable that the frame 80 has rigidity. The material of the frame 80 is not limited, and for example, insulating resin, ceramic, etc. can be used, and among these, insulating resin is preferable. Furthermore, among insulating resins, ABS resin (acrylonitrile-butadiene-styrene copolymer) is more preferable from the viewpoint of imparting adhesiveness to the frame 80 with the suspenders 70, pressure sensor 13, etc.

[0056] In this configuration, the base 60 is supported in a state of being suspended from the frame 80 via the suspenders 70. As a result, a space G is formed within the main body 10 of the beauty device 1 between the base 60 supporting the contactor 50 and the frame 80 supporting the pressure sensor 13. In this way, when no contact pressure P is generated on the contact surface 31 of the contact member 30, the contactor 50 is separated from the pressure sensor 13, and when contact pressure P is generated, the contactor 50 can come into contact with the pressure sensor 13 (see FIGS. 8, 9, and 19).

[0057] The mobile terminal 2 is a mobile communication terminal (e.g., a smartphone) equipped with computer functions. The mobile terminal 2 is connected to the beauty device 1 so as to be able to communicate wirelessly. Note that instead of the mobile terminal 2, a personal computer or the like connected via a wire may also be used as a communication terminal capable of wirelessly communicating with the beauty device 1. The mobile terminal 2 may also be connected to the beauty device 1 so as to be able to communicate via a network line, whether wired or wireless.

[0058] The mobile terminal 2 includes a main body, a display, and a camera (none of which are shown). The main body has a built-in computer and a communication module (not shown) that perform various processes such as calculation, control, storage, transfer, input, output, transmission, and reception of information. The main body also has a built-in auxiliary storage device (not shown), which stores a computer-readable program for applying or supporting the application operation of the beauty device 1 according to this embodiment.

[0059] The display visually displays information such as text and images output by the computer within the main body. The camera is a camera (or an in-camera) with a lens (not shown) provided on the display side of the mobile terminal. The camera is controlled by the computer within the main body, captures an image of the user U, and the image of the user U is captured.

[0060] The captured image of the user U is displayed on the display as a user image (not shown). The user image includes, for example, an area consisting of an image of the user U's face to which the cosmetic material is to be applied. Part of the area also includes an application area to which the cosmetic material is partially applied. By displaying various information in these areas, application or application operations using the cosmetic device 1 are supported.

[0061] In this embodiment, as described above, the electrodes 42, 43, which detect the presence of cosmetics on the surface of the skin in contact with the contact surface 31, are fitted into the contact member 30 so as to protrude from the contact surface 31, thereby enabling the detection of the presence of cosmetics on the contact surface 31 in contact with the skin (see FIGS. 8 to 10). Furthermore, when the electrodes 42, 43 are pressed into the contact member 30 by the contact pressure P generated on the contact surface 31, the contact member 30 into which the electrodes 42, 43 are fitted can bend. Furthermore, the electrodes 42, 43 pressed into the contact member 30 are slidably inserted through the base 60, allowing them to move within the base 60 (see FIGS. 19 and 20).

[0062] With this mechanism, in this embodiment, when the tips 42B, 43B of the electrodes 42, 43 are pressed, the contact member 30 deforms and can be displaced by a distance M so that the tips 42B, 43B of the electrodes 42, 43 are flush with the contact surface 31 (see FIGS. 19 and 20). As a result, when the contact surface 31 comes into contact with the skin, the tips 42B, 43B of the electrodes 42, 43 protruding from the contact surface 31 are less likely to cause an obstruction. Therefore, in this embodiment, it is possible to detect the cosmetic on the contact surface 31 that is in contact with the skin without interfering with the functions of the beauty device 1 (e.g., application operation, measurement of application pressure, measurement of application speed, etc.).

[0063] In this embodiment, as described above, the tips 42B, 43B of the electrodes 42, 43 form flanges, and the contact member 30 is formed with recesses 32, 33 into which the flanges 42B, 43B fit (see FIGS. 8 to 10). As a result, even if the tips 42B, 43B of the electrodes 42, 43 are pressed, the periphery of the recesses 32, 33 of the contact member 30 deforms, and the tips 42B, 43B of the electrodes 42, 43 can be displaced by a distance M so as to be flush with the contact surface 31 (see FIGS. 19 and 20). As a result, when the contact surface 31 comes into contact with the skin, only a portion of the contact member 30 deforms, and it is possible to provide a beauty device 1 in which the tips 42B, 43B of the electrodes 42, 43 protruding from the contact surface 31 are unlikely to cause an obstruction.

[0064] In this embodiment, as described above, by making the tips 42B, 43B of the electrodes 42, 43 curved, the tips 42B, 43B of the electrodes 42, 43 protruding from the contact surface 31 can smoothly contact the skin (see FIGS. 8 to 10, 13, 15, 16, 19, and 20). This reduces the discomfort felt by the skin when the contact surface 31 contacts the skin. Furthermore, since friction between the tips 42B, 43B of the electrodes 42, 43 and the skin can be reduced, the operation of the beauty device 1 (for example, application operation, etc.) becomes smoother.

[0065] In this embodiment, as described above, by forming the contact member 30 from an elastic material, the contact member 30 deforms when a pressing force (contact pressure P) is applied to the electrodes 42, 43 while maintaining the engagement of the electrodes 42, 43, and returns to its original shape when the pressing force (contact pressure P) on the electrodes 42, 43 is released (see FIGS. 8 to 12, 19, and 20). This allows the tips 42B, 43B of the electrodes 42, 43 to become flush with the contact surface 31 only when contact pressure P is applied to the contact surface 31 where the contact surface 31 comes into contact with the skin. Therefore, in this embodiment, the cosmetic on the contact surface 31 in contact with the skin can be detected with high accuracy without interfering with the function of the beauty device 1.

[0066] 21 and 22 are diagrams showing a beauty device according to a second embodiment. The beauty device 1 according to this embodiment is a beauty device having a contact surface that comes into contact with the skin via a sheet, and includes a main body, a base supported by the main body, a flexible contact member supported by the base and forming the contact surface, and an electrode that detects the cosmetic on the sheet with which the contact surface comes into contact, the electrode slidably passing through the base and fitting into the contact member so that the tip of the electrode protrudes beyond the contact surface.

[0067] Here, the sheet is made of paper, nonwoven fabric, resin film, etc., and is used while impregnated with a cosmetic. The contact surface that comes into contact with the skin via the sheet refers to the contact surface that comes into contact with the skin while covered with the sheet. The cosmetic on the sheet refers to the cosmetic ingredients contained in the sheet.

[0068] Specifically, in the beauty device 1 according to the second embodiment, a sheet S soaked in a cosmetic material is placed on the contact surface 31 of the contact member 30 in a state where it is fixed by a holder 38 in the beauty device 1 according to the first embodiment described above (FIGS. 2 to 20). The holder 38 is configured to include a frame 38A and a knob 38B. A user U can place the sheet S on the contact surface 31 by covering the contact surface 31 of the contact member 30 with the sheet S, pinching the knob 38B of the holder 38, and fitting the frame 38A of the holder 38 into the contact surface 31 (see FIGS. 21 and 22).

[0069] In this embodiment, the electrodes 42, 43 that detect the cosmetics on the sheet S that the contact surface 31 contacts are fitted into the contact member 30 so as to protrude from the contact surface 31, thereby making it possible to detect the cosmetics contained in the sheet S that the contact surface 31 contacts (see FIGS. 8 to 10). Furthermore, when the electrodes 42, 43 are pressed into the contact member 30 by the contact pressure P generated on the contact surface 31 that contacts the sheet S, the contact member 30 that fits the electrodes 42, 43 can bend. Furthermore, the pressed electrodes 42, 43 are slidably inserted through the base 60, and can move within the base 60 (see FIGS. 19 and 20).

[0070] With this mechanism, in this embodiment, when the tips 42B, 43B of the electrodes 42, 43 are pressed, the contact member 30 deforms and can be displaced by a distance M so that the tips 42B, 43B of the electrodes 42, 43 are flush with the contact surface 31 that contacts the sheet S (see FIGS. 19 and 20). As a result, when the contact surface 31 contacts the skin via the sheet S, the tips 42B, 43B of the electrodes 42, 43 that protrude from the contact surface 31 are less likely to cause an obstruction. Therefore, in this embodiment, the cosmetic material contained in the sheet S that contacts the contact surface 31 can be detected without interfering with the function of the beauty device 1.

[0071] <Cosmetic sensor> The cosmetic sensor according to this embodiment can be configured as a cosmetic sensor that constitutes part of the above-described beauty device 1. That is, cosmetic sensor 40 according to this embodiment is a cosmetic sensor that detects cosmetics on the surface of the skin that comes into contact with contact surface 31, and has electrodes 42, 43 that are slidably inserted into base 60 that supports flexible contact member 30 on which contact surface 31 is formed, and tips 42B, 43B of electrodes 42, 43 are fitted into contact member 30 so as to protrude from contact surface 31 (see FIGS. 1 to 18).

[0072] In this embodiment, the electrodes 42, 43 of the cosmetic sensor 40, which detects cosmetics on the surface of the skin with which the contact surface 31 comes into contact, are fitted to the contact member 30 so as to protrude from the contact surface 31, thereby enabling the detection of cosmetics on the contact surface 31 in contact with the skin (see FIGS. 8 to 10). Furthermore, when the electrodes 42, 43 are pressed into the contact member 30 by the contact pressure P generated on the contact surface 31, the contact member 30 into which the electrodes 42, 43 are fitted can bend. Furthermore, the electrodes 42, 43 pressed into the contact member 30 can slidably pass through the base 60 and move within the base 60 (see FIGS. 19 and 20).

[0073] Due to this mechanism, in this embodiment, when tips 42B, 43B of electrodes 42, 43 of cosmetic sensor 40 are pressed, contact member 30 deforms and displaces by distance M so that tips 42B, 43B of electrodes 42, 43 are flush with contact surface 31 (see FIGS. 19 and 20). As a result, when contact surface 31 comes into contact with the skin, tips 42B, 43B of electrodes 42, 43 of cosmetic sensor 40, which protrude from contact surface 31, are less likely to cause an obstruction. Therefore, in this embodiment, cosmetics on contact surface 31 in contact with the skin can be detected without interfering with the function of beauty device 1 equipped with cosmetic sensor 40 (see FIGS. 19 and 20).
