(Embodiment 1) FIGS. 1 to 4 show an embodiment of a light irradiation type beauty instrument according to the present invention. Front and back, left and right, and up and down in the present invention follow the crossed arrows shown in FIGS. As shown in FIG. 2, the light-irradiating beauty device has an irradiation head 2 at the lower end (one end) of a body case 1 that also serves as a grip. ing. A power switch 5 is provided on the upper part of the front surface of the main body case 1 . The body case 1 is moved to the right and left of the irradiation head 2 inside the body case 1 by a constant amount to reduce overlapping of the irradiation areas on the skin surface and to reduce passing movement of the irradiation areas on the skin surface. A shift means 6 is provided. The shift means 6 does not have to move the main body case 1 by a strictly constant amount, and even if variations in the amount of movement cause a slight overlap of the irradiation area or a slight movement through the irradiation area, it can be practically used. No problem above. Incidentally, with respect to the amount of movement by the shift means 6, it is preferable to set the amount of movement by the shift means 6 so that the irradiation area slightly overlaps rather than to slightly move the irradiation area, because the unprocessed skin surface does not remain. is preferred.

The irradiation head 2 is constructed by housing a light source 11 and a reflector 12 inside an irradiation case 10 having an inverted V-shaped cross section, and covering a lower opening of the irradiation case 10 with a transparent protective cover 13 . The light source 11 is composed of a straight tube-shaped xenon flash lamp, and the reflector 12 collects and reflects the high-intensity light emitted from the light source 11 and radiates it from the protective cover 13 toward the skin surface. The control board 4 is provided with a voltage adjustment circuit that adjusts the high-voltage current, a capacitor 14 that charges the high-voltage current, and the like. The light source 11 is turned on to emit pulsed light with a short light emission time. The protective cover 13 is flush with the lower end surface of the main body case 1 , and the lower end surface of the protective cover 13 serves as the light projecting section 15 .

The shift means 6 includes a pair of shift rollers (shift rotating bodies) 18, a support frame 19 that rotatably supports the rollers 18, and a rolling stop structure that stops and holds the shift rollers 18 each time they roll a predetermined amount. 20 and so on. The shift roller 18 is a roller made of plastic, and has shallow grooves formed on its peripheral surface to prevent slippage. Also, a rotation side detent body 28, which will be described later, is integrally provided on one side of the shift roller 18, and both of these 18 and 28 are rotatably supported by a roller shaft 21 fixed to the support frame 19. . The shift roller 18 is arranged within the contour line of the light projecting part 15 in close contact with the skin surface in order to make the appearance of the beauty device neat and improve its design.

The support frame 19 is guided and supported by a guide frame 22 provided on the main body case 1 so as to be vertically slidable. The support frame 19 is urged downward by a compression coil-type urging spring 24 disposed between a spring bearing seat provided on the main body case 1 and a switch arm 23, and the peripheral surface of the shift roller 18 is normally pressed. It is held in a protruding posture protruding from the light projecting part 15 to the skin surface side. In this state, the shift roller 18 is applied to the skin surface, and the body case 1 is pressed against the biasing force of the biasing spring 24 , so that the support frame 19 is formed so that the peripheral surface of the shift roller 18 and the light projecting portion 15 The light projecting part 15 can be brought into close contact with the skin surface by switching to a substantially flush operating posture. When the support frame 19 is switched to the operating posture, the lighting switch 25 is turned on by the switch arm 23, so that the high voltage current charged in the capacitor 14 is supplied to the light source 11 to turn on the light source 11. It can emit light. When the light projecting unit 15 is operated to move to a new irradiation area, the support frame 19 is held in a projecting posture by the biasing spring 24 and stands by in a state where light irradiation can be started at any time. In other words, the support frame 19 in Example 1 is held in a standby posture for irradiating light in the projecting posture.

The rolling stop structure 20 includes a rotating side detent body 28 provided integrally with the shift roller 18 , a fixed side detent body 29 fixed to the support frame body 19 , and the fixed side detent body 29 and the rotating side detent body 28 . and an elastic body 30 that moves and urges in the direction of engagement. Partially arcuate click recesses 31 are formed at four locations on the peripheral surface of the rotation-side detent body 28 at regular intervals. The fixed-side detent body 29 is made of a plate spring material and is formed in an inverted convex shape, and also serves as an elastic body 30. A click convex portion 32 of a partial circular arc that engages with the click concave portion 31 is formed on the lower surface side thereof. It is According to the rolling stop structure 20 , the click concave portion 31 engages the click convex portion 32 every time the shift roller 18 makes a quarter turn, thereby stopping and holding the shift roller 18 . At this time, as shown in FIG. 4, the relationship between the distance R over which the shift roller 18 rolls and the front-to-rear width L of the light projecting portion 15 (protective cover 13) preferably satisfies (R=L). , the dimensional relationship may satisfy (R≈L) and satisfy (R<L) at the same time. In other words, it may be set such that the irradiation regions slightly overlap due to variations in the amount of movement.

When using the beauty instrument, the power switch 5 is turned on to start charging the capacitor 14 with a high voltage current, and wait until an LED (not shown) indicating the completion of charging lights up (about 3 hours). seconds). With the LED turned on, the shift roller 18 is applied to the skin surface that needs to remove unwanted hair, the body case 1 is pressed against the skin surface while resisting the spring force of the biasing spring 24, and the light projecting part 15 is pressed against the skin surface. adhere to the surface. Since the lighting switch 25 is turned on by the switch arm 23 at the same time when the light projecting part 15 comes into close contact with the skin surface, the high voltage current charged in the capacitor 14 is supplied and the light source 11 emits light. In addition, when the light source 11 emits light, the skin surface is irradiated with high-intensity pulsed light with a short emission time, thermally damaging the hair roots of the unwanted hair, and preventing the unwanted hair from regenerating. be able to.

Next, the pressing force applied to the main body case 1 is released to float the light projecting part 15 away from the skin surface, and the main body case 1 is moved to the next unwanted hair processing position while the shift roller 18 is rolled. That is, each time the light source 11 is caused to emit light to irradiate the skin surface with high-intensity pulsed light, the body case 1 is moved by a constant amount. Aim for a length of However, in practice, variations in the amount of movement often result in slight overlap of the irradiation areas and slight movement through the irradiation areas. It shall include the state where As the main body case 1 moves, the click concave portion 31 elastically deforms the fixed-side detent body 29 and escapes from the click convex portion 32. When the shift roller 18 rotates one-fourth of a turn from the start of movement, the click convex is released. The portion 32 drops into and engages with the click recess 31 to stop and hold the shift roller 18 . In this state, after confirming that the LED indicating the charging completion state is lit, the main body case 1 is again pressed against the skin side while resisting the spring force of the biasing spring 24, and the light projecting portion 15 is moved to the skin. It is brought into close contact with the surface, and the light emitting source 11 is caused to emit light to remove unwanted hair.

Thereafter, the body case 1 is moved and the light emission source 11 is repeatedly emitted to remove unwanted hair from the skin surface in a necessary range. When the unwanted hair is removed, the power switch 5 is turned off to stop charging the capacitor 14 with the high voltage current. When the shift roller 18 is switched to the projecting posture, the light projecting part 15 is floating away from the skin surface, so when moving to a new irradiation area, the light projecting part 15 is in sliding contact with the skin surface, giving an uncomfortable feeling. Alternatively, it is possible to prevent the application of unpleasant sliding contact stimulation.

The moving distance when the main body case 1 is moved is set to be the same as or slightly smaller than the front-rear width of the irradiation area of the irradiation head 2 . Therefore, when the main body case 1 is moved to irradiate the skin surface with light, the previous irradiation area and the new irradiation area largely overlap, and an increase in the number of irradiation times of the light source 11 in one cosmetic treatment can be avoided. can be prevented. Therefore, early deterioration of the light source 11 can be eliminated, and the beauty instrument can be used continuously for a long period of time. In addition, since the shift roller 18 can be stopped and held by the rolling stop structure 20 each time the shift roller 18 makes a quarter turn, it is possible to reduce variations in the amount of movement when the irradiation head 2 is shifted. It is possible to prevent the movement from occurring, and it is possible to effectively prevent an untreated skin surface that has not been irradiated with the pulsed light from remaining between the previously irradiated region and the new irradiated region.

According to the beauty tool described above, the rotation-side detent body 28 and the fixed-side detent body 29 are engaged with each other every time the shift roller 18 rotates by a predetermined amount, so that the shift roller 18 can be properly stopped and held. Therefore, the amount of rotation of the shift roller 18 can be reduced, and the waste hair can be removed evenly and accurately. Further, since the shift roller 18 is rotatably supported by the support frame 19, the shift roller 18 rolls along the skin surface, thereby moving the main body case 1 along the skin surface by a certain amount. You can move smoothly one by one. Therefore, compared with the case where the shift rotator is composed of a rotator that does not have a roller structure, it is possible to eliminate variations in the amount of movement of the irradiation head 2 .

Since the shift rollers 18 are arranged on both left and right sides of the irradiation head 2 perpendicular to the moving direction of the main body case 1, the entire weight of the beauty device can be supported by the pair of shift rollers 18, and the movement of the irradiation head 2 can be stabilized. It can be performed properly in a state where Further, since the shift rollers 18 are arranged on both the left and right sides of the irradiation area, the shift rollers 18 can be properly rotated while clearly visually checking the previous irradiation area and the new irradiation area. For example, as shown in FIG. 6, if the shift roller 18 is provided at either the front or rear of the main body case 1, it may interfere with viewing the irradiation area. Further, since the shift roller 18 is arranged within the contour line of the skin contact surface of the main body case 1, most of the shift means 6 is covered with the main body case 1, so that the shift means 6 is visible and gives a complicated impression. can be avoided as much as possible, and the appearance design of the beauty instrument can be improved.

(Example 2) Fig. 5 shows a beauty instrument according to Example 2 in which the rolling stop structure 20 is changed. In this beauty tool, a rotation-side detent body 28 is provided separately from the shift roller 18, a driving gear 35 is provided integrally with the shift roller 18, and a driven gear 36 is provided integrally with the rotation-side detent body 28. The gear ratio between the drive gear 35 and the driven gear 36 is set to 1:2, and the rotation-side detent body 28 rotates once when the shift roller 18 rotates twice. A driven gear 36 integrated with the rotation-side detent body 28 is rotatably supported by a gear shaft 37 fixed to the support frame 19 , and the click recess 31 is formed only at one place on the peripheral surface of the rotation-side detent body 28 . was established. The beauty device of Example 2 is used in the same manner as the beauty device of Example 1, but when the shift roller 18 makes two revolutions, the click projection 32 drops into the click recess 31 and engages to shift. The difference is that the roller 18 is stopped and held. The support frame 19 in Example 2 is held in a standby posture for irradiating light in a protruded posture, as in the case of the support frame in Example 1. As shown in FIG.

According to the beauty device of Example 2, when the distance moved from the previous irradiation region to the new irradiation region is constant, the diameter of the shift roller 18 is significantly reduced, compared to the beauty device of Example 1. The shift roller 18 can be made smaller and more compact. In addition, when the shift roller 18 is arranged within the contour line of the skin contact surface of the main body case 1, the conspicuousness of the shift roller 18 can be eliminated by the amount that the shift roller 18 can be made small, thereby improving the appearance of the beauty device. You can improve the design. In this embodiment as well, the main body case 1 is moved by a constant amount by the shift means 6. The constant amount is aimed at a distance corresponding to the length of the short side of the effective irradiation surface of the light projecting section 15. The same applies to the third embodiment and subsequent embodiments. Since other points are the same as those of the first embodiment, the same reference numerals are given to the same members, and the description thereof is omitted. The same applies to the third embodiment and subsequent embodiments.

(Embodiment 3) FIGS. 6 to 8 show a beauty instrument according to Embodiment 3 of the present invention, in which the shifting means 6 and the rolling stop structure 20 are changed. There, the shift means 6 is composed of the shift roller 18 arranged on the rear side of the main body case 1 (one side in the moving direction of the irradiation head 2 ) and the support frame 19 that rotatably supports the shift roller 18 . The shift roller 18 consists of a roller elongated in the left and right direction, and rotary side detent bodies 28 are integrally provided on both sides thereof. Click recesses 31 are provided at three locations on the peripheral surface of the rotation-side detent body 28 at regular intervals. The fixed-side detent body 29 is formed in a lying convex shape and fixed to the lower rear surface of the main body case 1 . A lighting switch 25 for lighting the light source 11 is provided on the upper surface of the body case 1 .

A pair of guide frames 40 are provided on the left and right sides of the rear surface of the main body case 1 so that the support frame 19 can be switched between a projecting posture, an operating posture, and a retracted posture. Guided and supported freely. The support frame body 19 is formed in a gate shape, and slide pieces 41 projecting from the right and left ends of the upper frame are slidably guided by guide frames 40 . A position holding structure is provided on the facing surfaces of the guide frame 40 and the support frame 19 in order to hold the support frame 19 in each of the protruded posture, the operating posture, and the retracted posture. The position holding structure is composed of a partially spherical clicking concave portion 42 formed at three upper and lower portions of the guide frame 40 and a partially spherical clicking convex portion 43 provided on the slide piece 41 side.

In the beauty device of Example 3, the supporting frame 19 is switched to the operating posture (the state shown in FIG. 6) in which the circumferential surface of the shift roller 18 slightly protrudes from the light projecting portion 15, and the shift roller 18 stops rolling. When the lighting switch 25 is turned on while being stopped and held by the structure 20, the light emitting source 11 emits light to remove unwanted hair. In addition, every time the body case 1 is moved from the previous irradiation area to a new irradiation area, the lighting switch 25 is pressed to cause the light emitting source 11 to emit light, thereby performing intermittent hair removal. can. In the operating posture, the peripheral surface of the shift roller 18 is made to protrude slightly beyond the light projecting section 15 because the shift roller 18 sinks into the soft skin surface when light is irradiated, allowing the light projecting section 15 to adhere to the skin surface. is. Also, after light irradiation, the light projecting portion 15 is lifted off the skin surface, and the shift roller 18 can be rotated toward the next irradiation area without any trouble.

When the supporting frame 19 is switched to the protruding posture (the state shown in FIG. 8) in which the circumferential surface of the shift roller 18 protrudes downward from the light projecting portion 15, the rotating side detent body 28 is separated from the fixed side detent body 29. Thus, the shift roller 18 can rotate freely. By rolling the shift roller 18 along the skin surface in this state, it is possible to give a rolling stimulation or rubbing stimulation to the skin surface, thereby enhancing the beauty effect. At this time, since the light projecting part 15 is separated from the skin surface, the light projecting part 15 is prevented from becoming an obstacle when performing cosmetic treatment with the shift roller 18, and the cosmetic treatment by the shift roller 18 is lightened. can do When the support frame 19 is in the retracted position in which the peripheral surface of the shift roller 18 is positioned above the light projecting unit 15, when the skin between the nose and the lips is irradiated with light for cosmetic treatment, the shift roller 18 can be shifted. The convenience of the beauty instrument can be improved by eliminating the obstruction of the roller 18.例文帳に追加As described above, the support frame 19 is supported by the main body case 1 so as to be switchable between the projecting posture and the operating posture and between the operating posture and the retracted posture. The support frame 19 that has been switched to the projecting posture is held in a roller posture for using the shift roller 18 as a cosmetic roller.

(Embodiment 4) FIGS. 9 to 11 show a beauty instrument according to Embodiment 4 in which the shifting means 6 and rolling stop structure 20 are changed. In this case, the support frame 19 is swingably supported by a swing shaft 45 fixed to the main body case 1 so that the support frame 19 can be switched between a projecting posture, an operating posture, and a retracted posture. Further, the support frame 19 is configured in the shape of a hollow case, in which a fixed gear 46 fixed to the swing shaft 45, an intermediate gear 47 meshing with the fixed gear 46, and a final gear meshing with the intermediate gear 47 are provided. A gear 48 and a rotation-side detent body 28 arranged adjacent to the final stage gear 48 are arranged. The intermediate gear 47 and the final stage gear 48 are rotatably supported by the case wall of the support frame 19 , and the rotation-side detent body 28 is fixed to the roller shaft 21 of the shift roller 18 . The final stage gear 48 is formed as a sector gear, and a triangular frame-shaped click protrusion 32 is integrally formed on the peripheral surface on which gear teeth are not formed, and the final stage gear 48 itself serves as a fixed-side articulator. 29. The shift roller 18 consists of rollers that are long in the left and right direction, like the shift roller 18 of the third embodiment.

In order to hold the support frame 19 in each of the protruded posture, the operating posture, and the retracted posture, a position holding structure is provided on the facing surfaces of the main body case 1 and the support frame 19 . As shown in FIG. 9, the position holding structure includes a steel ball 50 accommodated in a ball hole 49 formed in the main body case 1, a compression coil spring 51, and a depression formed on the support frame 19 side. It is composed of three partially spherical engaging recesses 52 and the like. When the support frame 19 is switched to each of the protruded posture, the operating posture, and the retracted posture, the balls 50 drop and engage with the respective engaging recesses 52, so that the support frame 19 can be held in each posture. can be done. A lighting switch 25 for lighting the light source 11 is provided on the front surface of the body case 1 (see FIG. 10).

As shown in FIG. 10, when the support frame 19 is switched to the projecting posture, the click protrusion 32 is separated from the rotation-side detent body 28, allowing the shift roller 18 to rotate freely. By rolling the shift roller 18 along the skin surface in this state, it is possible to give a rolling stimulation or rubbing stimulation to the skin surface, thereby enhancing the beauty effect. Thus, the support frame 19 that has been switched to the projecting posture is held in the roller posture for using the shift roller 18 as a cosmetic roller. When the support frame 19 is switched from the protruded posture to the operating posture, the intermediate gear 47 rotates counterclockwise while meshing with the fixed gear 46, and the final stage gear 48 rotates clockwise. Therefore, the click projection 32 gradually approaches the rotation-side detent body 28, and when the support frame 19 is switched to the operating posture as shown in FIG. to prevent the shift roller 18 from rolling. Also, the ball 50 is dropped into the second engaging recess 52 to hold the support frame 19 in the operating posture. When the support frame 19 is switched from the operating posture to the retracted posture, the shift roller 18 is accommodated in the recessed storage portion 53 formed in the main body case 1, thereby improving usability of the beauty device.

Since the lower peripheral surface of the shift roller 18 in the above state protrudes slightly from the light projecting portion 15 of the irradiation head 2, by pressing the lighting switch 25 while pressing the light projecting portion 15 against the skin surface, Unwanted hair can be removed by causing the light emitting source 11 to emit light. In addition, each time the main body case 1 is moved from the previous irradiation area to a new irradiation area, the rolling stop structure 20 prevents the shift roller 18 from rolling to prevent overlapping of the irradiation areas on the skin surface. can. Furthermore, the rolling stop structure 20 prevents the irradiation area from moving across the skin surface, so that unwanted hair can be removed evenly and accurately. As described above, in the beauty device of the fourth embodiment, the intermediate gear 47 and the final stage gear 48 are rotationally driven in conjunction with the swinging operation of the support frame 19 from the protruded posture to the operating posture, and fixed. The side detent body 29 engages with the rotating side detent body 28 to stop and hold the shift roller 18 .

(Embodiment 5) FIG. 12 shows a beauty instrument according to Embodiment 5 in which the shifting means 6 is changed. There, the shift roller 18 rotatably supported by the support frame 19 is rotationally driven through the gear train 57 by the rotational power of the motor 56 mounted on the support frame 19 as in the first embodiment. made self-propelled. The gear train 57 transmits the rotational power of the motor 56 at a reduced speed to slowly rotate the shift roller 18 . The support frame 19 is guided and supported by the main body case 1 so as to be vertically movable, and is pressed down by a biasing spring 24. In a normal state, the peripheral surface of the shift roller 18 is directed from the light projecting portion 15 to the skin surface side. It is held in a protruding protruding posture. As described above, in this embodiment, a driving structure including the motor 56 and the gear train 57 is provided inside the main body case 1 so that the shift roller 18 is rotationally driven by the power of the motor 56 . Further, the shift roller 18 is intermittently rotationally driven by the drive structure, and the shift roller 18 is stopped and held each time the light projecting section 15 of the irradiation head 2 faces a new irradiation area. Further, a self-propelled switch 26 is provided on the fixed wall of the main body case 1, and a switch operation arm 27 is provided on the support frame 19, so that the self-propelled switch 26 is operated when the support frame 19 is switched from the operating posture to the projecting posture. A switch operating arm 27 is turned on to start a motor 56. - 特許庁In addition, the motor 56 is stopped while the shift roller 18 faces the new irradiation area.

When using the beauty instrument, after waiting for the LED indicating the charging completion state to be turned on, the shift roller 18 is applied to the skin surface requiring removal of unwanted hair, and the body case 1 is pushed by the spring force of the biasing spring 24. The projection part 15 is brought into close contact with the skin surface by pressing against the skin surface while resisting. Since the lighting switch 25 is turned on by the switch arm 23 at the same time when the light projecting part 15 comes into close contact with the skin surface, the high voltage current charged in the capacitor 14 is supplied and the light source 11 emits light. Next, when the pressing force applied to the body case 1 is released, the support frame 19 switches from the operating posture to the projecting posture, and the self-propelled switch 26 is turned on. is self-propelled toward a new irradiation area. Furthermore, since the motor 56 stops when the beauty tool moves to a new irradiation area, the main body case 1 is pressed against the skin surface again to bring the light projecting part 15 into close contact with the skin surface, and the light emitting source 11 emits light. Perform beauty treatment. After that, the movement of the beauty tool and the light emission of the light source 11 are alternately performed to remove unwanted hair on the skin surface in a necessary range. When the power switch 5 is turned on to use the beauty equipment, there is a possibility that the support frame 19 is switched to the projecting posture and the self-propelled switch 26 is turned on. is not activated, and the motor 56 is activated only when the lighting switch 25 is turned on, and then the support frame 19 is switched to the projecting posture and the self-propelled switch 26 is turned on. In the beauty instrument according to the fifth embodiment configured as described above, the motor 56 and the gear train 57 that rotationally drive the shift roller 18 function as the shift means 6, and the motor 56 further functions as the rolling stop structure 20. are doing. As with the support frame 19 of the first embodiment, the support frame 19 of the fifth embodiment is held in a standby posture for irradiating light in the projected posture.

In the beauty tool of Example 5, the shift roller 18 is rotationally driven by a driving structure that uses the rotational power of the motor 56 as a drive source, so that the beauty tool is self-propelled and the light projecting section 15 approaches a new irradiation area. can let Therefore, compared to the case where the user moves the main body case 1 to bring the light projecting part 15 to face a new irradiation area, it is possible to eliminate large fluctuations in the amount of movement of the light projecting part 15 . In addition, the shift roller 18 is intermittently rotated by the driving structure, and is stopped and held each time the light projecting part of the irradiation head 2 faces a new irradiation area. It can be self-propelled and the overlap of the illuminated areas or the over-movement of the illuminated areas can be further reliably reduced. When using the beauty instrument, the user only needs to hold the main body case 1 in a proper posture, so that the beauty treatment can be carried out easily without the trouble required for the beauty treatment. Moreover, since the rolling stop structure 20 can be omitted, the structure of the beauty instrument can be simplified.

(Example 6) Figs. 13 and 14 show a beauty instrument according to Example 6 in which the shifting means 6 is changed. There, a cylindrical cap frame 59 is detachably attached to the outer surface of the irradiation head 2 of the main body case 1, and the cap frame 59 supports the support frame body 19 so as to be switchable between a projecting posture, an operating posture, and a retracted posture. made it The support frame 19 switched to each posture is held by the position holding structure described in the fourth embodiment. Further, a recumbent J-shaped roller housing portion 60 is provided on the upper rear surface of the cap frame 59 , and a triangular frame-shaped click convex portion 32 is provided at the free end of the roller housing portion 60 that also serves as the fixed-side detent body 29 . When the support frame 19 is switched to the operating posture, the click protrusion 32 is engaged with the click recess 31 of the rotating side detent body 28 that rotates together with the shift roller 18, and the shift roller in this state. The peripheral surface of 18 slightly protrudes from the light projecting portion 15 of the irradiation head 2 . A lighting switch 25 for lighting the light source 11 is provided on the front surface of the body case 1 (see FIG. 13). The cap frame 59 in this embodiment does not need to be formed in a cylindrical shape, and may be formed in a C-shaped cross section or in a cylindrical body whose cylindrical wall is divided by a plurality of longitudinal grooves.

When the beauty tool is used, similarly to the beauty tool of the fourth embodiment, the lighting switch 25 is pressed while the light projecting part 15 is pressed against the skin surface, so that the light source 11 emits light to remove unwanted hair. It can be performed. As shown in FIG. 13, when the cap frame 59 is removed from the main body case 1 and the support frame 19 is switched to the projecting posture, the shift roller 18 becomes rotatable. By rolling, a rolling stimulus or a rubbing stimulus can be given to the skin surface, and the cosmetic effect can be enhanced. When the support frame 19 is switched to the retracted posture, the shift roller 18 is held on the front side of the main body case 1, contrary to the operating posture.

According to the beauty tool of the sixth embodiment, when the support frame 19 is switched to the operating posture, the shift roller 18 is housed in the roller housing portion 60, so that other objects may contact the shift roller 18 by mistake. As a result, the roller accommodating portion 60 can prevent the support frame 19 from being switched to the projecting posture. In addition, since the cap frame 59 removed from the body case 1 can be used to apply a rolling stimulus or a rubbing stimulus to the skin surface, the support frame body 19 can be applied to the body case 1 while the rolling stimulus is applied. Compared to the case, the cosmetic treatment can be easily and simply performed. Furthermore, since the support frame 19 is held by the position holding structure in a state of being switched to each posture, it is possible to reliably prevent the posture of the support frame 19 from being changed unless the user has a clear intention. . The support frame 19 that has been switched to the projecting posture is held in a roller posture for using the shift roller 18 as a cosmetic roller.

(Embodiment 7) FIGS. 15 and 16 show a beauty instrument of Embodiment 7 in which the shifting means 6 is changed. There, a hollow cylindrical shift rotor 18 arranged at the lower end of the main body case 1 is rotatably supported by a support frame 19 . The shift rotator 18 has a regular hexagonal cross section, and inside it, there are an irradiation head 2 having an irradiation case 10, a light source 11, and a reflector 12, and a head frame 62 for fixedly supporting the head 2. established. The head frame 62 is integrated with the roller shaft 21 provided on the support frame 19 and supports the irradiation head 2 in a fixed manner. As shown in FIG. 16, the shift rotator 18 has a base frame 18a and a transparent irradiation window plate 18b fixed to each side, and the bearings 18c at both ends can be rotated by the roller shaft 21. supported by A protective cover 13 of the irradiation head 2 is formed in a downwardly curved shape. The body case 1 is supported by a support frame 19 so as to be vertically movable, and is pushed up by a biasing spring 24 .

In use, by pushing down the body case 1 with the irradiation window plate 18b in close contact with the skin surface, the lighting switch 25 is switched to the ON state and the light source 11 emits light to remove unwanted hair. . Next, the pressing force on the main body case 1 is released, and with the lighting switch 25 turned off, the shift rotor 18 is rotated to move the beauty tool to a new irradiation area. When the beauty tool is operated to move, the side portion including the irradiation window plate 18b is received by the skin surface every one-sixth rotation of the shift rotator 18, and the state can be maintained.

As described above, the side portions (stable peripheral surfaces) 63 between the adjacent top portions of the shift rotor 18 come into contact with the skin surface to prevent rolling, so the shift rotor 18 itself has a rolling stop structure. It can double as 20. Therefore, the manufacturing cost can be reduced by simplifying the structure of the beauty instrument by the amount that the rolling stop structure 20 can be omitted. Further, since the irradiation head 2 is housed inside the shift rotor 18, the shift rotor 18 can receive the drop impact, and the light source 11 can be well prevented from being damaged by the drop impact. Since the irradiation head 2 is fixedly supported by the head frame 62, even when the shift rotator 18 rotates toward a new irradiation area, the irradiation head 2 is positioned on the extension of the main body case 1, and both The positional relationship between 1 and 2 is always constant. Therefore, when using the beauty tool, the light projecting part 15 can be directly faced to the skin surface and appropriate beauty treatment can be performed only by placing the main body case 1 in the orthogonal posture with respect to the skin surface. Therefore, it is possible to reliably prevent misuse in which the light source 11 emits light when the main body case 1 is inclined with respect to the skin surface and the irradiation window plate 18b, which does not face the light projecting part 15, is in contact with the skin surface. . Note that the shift rotor 18 may be formed in a cylindrical shape.

(Embodiment 8) FIGS. 17 to 19 show a beauty instrument of Embodiment 8 in which the shifting means 6 is changed. There, the irradiation head 2 is fixed to one end of the body case 1 that also serves as a grip, and a cylindrical shift roller 18 is arranged around it. The peripheral surface of the irradiation case 10 and the protective cover 13 that constitute the irradiation head 2 are formed in a continuous circular cross-section, and the base end of the irradiation case 10 is fixed to the main body case 1 . The shift roller 18 has a transparent cylindrical irradiation cylinder wall 64 , and a moderation ring 65 fixed to the base end side of the wall 64 is rotatably cantilevered on the body case 1 . A rolling stop structure 20 is provided between the body case 1 and the moderation ring 65 . In FIG. 19, the rolling stop structure 20 includes a steel ball 67 housed in a ball hole 66 formed in the body case 1, a compression coil spring 67a, and four dents formed on the inner surface of the detent ring 65. of engagement recesses 69.

Next, after waiting for a capacitor (not shown) to be charged with a high voltage current, the shift roller 18 is rotated. Drop-in engagement allows the shift roller 18 to be held stationary. After that, the light emission of the light source 11 and the rotational movement of the shift roller 18 are alternately performed to remove unwanted hair from the necessary area of the skin surface.

(Embodiment 9) FIG. 20 shows a beauty instrument of Embodiment 9 in which the shifting means 6 is changed. There, the shift rotor 18 is formed in the shape of an equilateral triangle with three tops 68 . According to this shift rotator 18, each time the shift rotator 18 rolls over the top 68 toward a new irradiation area by a predetermined amount, the side portion (stabilization) between the adjacent tops 68 of the shift rotator 18 is changed. The peripheral surface) 63 contacts the skin surface to prevent rolling. In this way, if the shift rotator 18 itself also serves as the rolling stop structure 20, the structure of the beauty instrument can be simplified to the extent that the rolling stop structure 20 can be omitted, and the manufacturing cost can be reduced. In addition, when the shift rotator 18 rotates, the light projecting part 15 is separated from the skin surface, so that unnecessary rubbing of the skin surface by the light projecting part 15 can be eliminated and the skin surface can be protected. . Furthermore, the shift rotor 18 can be stopped and held in a stable state as compared with the shift rotor 18 having an elliptical shape, which will be described below. As can be appreciated from this embodiment, the shift rotor 18 can be formed in the shape of a regular polygon with three or more apices 68 .

(Embodiment 10) FIG. 21 shows a beauty device of Embodiment 10 in which the shifting means 6 is changed. There, the outer shape of the shift rotor 18 is formed in an elliptical shape with a pair of top portions 68 . According to this shift rotator 18, every time the shift rotator 18 rolls over the top 68 toward a new irradiation area by a predetermined amount, the peripheral surface (stability) between the adjacent tops 68 of the shift rotator 18 is changed. The peripheral surface) 63 contacts the skin surface to prevent rolling. The peripheral surface 63 serving as the stable peripheral surface is a peripheral surface having a large radius of curvature that contacts the skin surface while intersecting the minor axis of the ellipse. In the shift means 6 according to this embodiment, the shift rotator 18 itself also serves as the rolling stop structure 20 in the same way as the shift means 6 according to the ninth embodiment. The structure can be simplified and the manufacturing cost can be reduced.

(Embodiment 11) FIGS. 22 and 23 show a beauty instrument of Embodiment 11 in which the shifting means 6 is changed. There, the shift means 6 is composed of four protruding structures 70 provided near the peripheral corners of the light projecting portion 15 of the irradiation head 2, and the structures 70 are compression coil springs (elastic bodies) 71. , pushing and biasing in the direction of advancing from the irradiation case 10 . The protruding structure 70 is formed in the shape of a round shaft, has a circular depression 72 formed at its lower end, and forms a ring-shaped shaped portion 73 around the depression 72 .

When using a beauty tool, the light emitting part 15 is brought into close contact with the skin surface while resisting the spring force of the spring 71 to cause the light emitting source 11 to emit light. At this time, the shaping portion 73 bites into the skin surface, and four ring-shaped pressing marks are formed on the skin surface. By making the light projecting unit 15 face the new irradiation area, the previous irradiation area and the new irradiation area can be adjacent to each other just enough. Especially in this embodiment, since the center of the projecting structure 70 is positioned on the extended line of the long side of the light projecting section 15, the previous irradiation area and the new irradiation area can be accurately connected. In addition, since only a plurality of projecting structures 70 are provided around the light projecting part 15, the structure of the beauty instrument can be significantly simplified and lowered compared to the shift means 6 having the shift rotator 18 as a moving element. Cost can be reduced. Furthermore, since the protruding structure 70 is urged forward by the spring 71, when the protruding structure 70 is pressed against the skin surface, the elastic body 71 is elastically deformed to absorb excessive pressing force. Therefore, it is possible to prevent the shaping portion 73 from unnecessarily digging into the skin surface, and to avoid damage to the skin surface due to deep pressing traces.

(Embodiment 12) FIG. 24 shows a beauty instrument of Embodiment 12 in which the projecting structure 70 is changed. There, the protruding structure 70 is formed by a rectangular frame-shaped protruding rib surrounding the periphery of the light projecting section 15, and a mesh-shaped shaping section 73 is protrusively formed on the protruding end surface thereof. Similar to the protruding structure 70 described in the eleventh embodiment, the protruding structure 70 of this embodiment has a protruding end surface of the protruding structure 70 when the light projecting part 15 is brought into close contact with the skin surface and the light emitting source 11 is caused to emit light. Then, the shaping portion 73 bites into the skin surface, and a rectangular frame-shaped pressing trace and a mesh-like pressing trace are formed on the skin surface. When the beauty tool is moved to a new irradiation area, the previous pressing trace is used as an index to direct the light projecting part 15 to face the new irradiation area. The previous irradiation area and the new irradiation area can be adjoined just enough by making the light projecting part 15 face the new irradiation area in a state of overlapping with the inner peripheral edge of the square frame-shaped pressing trace.

(Embodiment 13) FIG. 25 shows a beauty instrument of Embodiment 13 in which the projecting structure 70 is changed. There, the shift means 6 is composed of four stamp bodies 74 provided near the peripheral corners of the light projecting section 15 . The stamp body 74 is composed of a shaping portion 73 formed of a round shaft-shaped porous rubber material and an ink absorbing mat 75 arranged adjacent to the shaping portion 73. The shaping portion 73 is pressed against the skin surface. Thus, stamp traces can be formed continuously. The printing ink stored in the ink-absorbing mat 75 can be easily erased with tissue paper or the like, and is made of plant-derived dye-based ink that does not cause rough skin or eczema. It is formed by diluting the undiluted ink with water.

When using a beauty tool, the light projecting part 15 is brought into close contact with the skin surface and the light emitting source 11 emits light. At this time, the shaping unit 73 is in close contact with the skin surface and four stamp marks are formed. can be made to face the new irradiation area. Therefore, it is possible to perform beauty treatment evenly by preventing overlap of irradiation areas or movement of irradiation areas. Further, since a plurality of stamp bodies 74 are simply provided around the light projecting part 15, the structure of the beauty instrument can be significantly simplified and the cost can be reduced compared to the shift means 6 having the shift rotary body 18 as a moving element. . Since the center of the stamp body 74 is positioned on the extended line of the long side of the light projecting part 15 as in the projecting structure 70 of the eleventh embodiment, the previous irradiation area and the new irradiation area are accurately connected. be able to.

(Embodiment 14) FIG. 26 shows a beauty instrument with a modified switch structure for causing the light source 11 to emit light. There, a switch structure is provided between the shift roller 18 and the support frame 19 to permit the supply of the drive current to the light source 11 . Specifically, a conductive terminal 78 is embedded and fixed in the click concave portion 31 of the rotating side detent body 28 , and a pair of contact terminals 79 electrically connected by the conductive terminal 78 is provided in the click convex portion 32 of the fixed side detent body 29 . The control circuit 80 supplies a high-voltage driving current to the light emitting source 11 to emit light under the lighting condition that these terminals 78 and 79 are electrically connected. The conductive terminal 78 and the contact terminal 79 constitute a switch 81 for turning on the light source 11 . According to such a switch structure, every time the shift roller 18 stops, the light emitting source 11 can automatically emit light to perform cosmetic treatment.

According to the above-described switch structure, the light source 11 can automatically emit light at the same time that the shift roller 18 rolls a predetermined amount and stops. . Therefore, the time and effort required for the cosmetic treatment can be further saved, and the cosmetic treatment can be performed more easily. In addition, according to this switch structure, every time the shift roller 18 stops, the light source 11 can be turned on to emit light.

(Embodiment 15) FIG. 27 shows a beauty instrument of Embodiment 15 in which the switch structure for causing the light source 11 to emit light is further modified. In this case, the switch 81 is constructed by providing a pair of contact terminals 79 that come into contact with the skin surface on each side of the shift rotor 18 formed in the shape of an equilateral triangle. According to such a switch structure, the pair of contact terminals 79 become conductive through the skin surface at the same time when the shift rotor 18 rolls by a predetermined amount and stops. can supply a high voltage driving current to the light emitting source 11 to emit light. Therefore, like the beauty instrument of the fourteenth embodiment, it is possible to save the user's time and effort and quickly remove unwanted hair.

(Embodiment 16) Figs. 28 and 29 show a beauty instrument in which the shift means 6 is changed and the switch structure for causing the light source 11 to emit light is changed. There, an accommodation pocket 83 is provided on the rear side of the light projecting unit 15 of the irradiation case 10, and an LED light source 84, a condenser lens 85, and a CMOS image sensor 86 are accommodated therein. The shift means 6 is configured with a shift notification structure. Reference numeral 87 is a projection window. The shift notification structure emits at least one notification signal of light, sound, and vibration to notify the user that the irradiation case 10 has moved by a predetermined amount.

When using a beauty tool, the light projecting part 15 is brought into close contact with the skin surface and the light emitting source 11 emits light. Next, the beauty tool is moved to a new irradiation area. At this time, since the amount of movement of the irradiation case 10 can be known from the difference in the image read by the CMOS image sensor 86, when the irradiation case 10 has moved a predetermined amount, Then, the shift notification structure (not shown) is activated, the movement of the irradiation case 10 is stopped, and the light projecting section 15 can be made to face the new irradiation area. According to the beauty instrument that optically reads and quantifies the amount of movement of the irradiation case 10 and notifies it by the shift notification structure, the previous irradiation area and the new irradiation area can be adjacent to each other just enough. Simultaneously with the operation of the shift notification structure, a high-voltage drive current can be supplied to the light emitting source 11 to emit light, so the shift means 6 can also serve as a switch structure for causing the light emitting source 11 to emit light. In this way, the operation of the shift notification structure and the lighting of the light source 11 may be performed at the same time. can be controlled to In that case, since the shift notification structure can notify in advance that the light emitting source 11 will be turned on soon, the user should prepare mentally for the light emission or take preventive measures such as looking away from the light emitting area. be able to. Incidentally, when the operation of the shift notification structure and the lighting of the light source 11 are simultaneously performed, the user cannot take the preventive measures described above, so that the user feels uncomfortable or surprised until he/she gets used to handling the beauty device. may be

According to the shift means 6 configured as described above, every time the light projecting section 15 is moved by a predetermined amount, a notification signal can be emitted in the shift notification structure so that the light projecting section 15 faces a new irradiation area. Therefore, it is possible to prevent overlapping of the irradiation areas or movement of the irradiation areas so that the cosmetic treatment can be performed evenly. Also, by confirming any one of light, sound, and vibration, it is possible to sensuously recognize that the light projecting unit 15 has faced a new irradiation area, so it is not necessary to move the light projecting unit 15 slowly. It is possible to improve the usability of the beauty instrument by quickly moving and operating it. Furthermore, every time the light projecting unit 15 faces a new irradiation area, a driving current can be supplied to the light emitting source 11 to automatically cause the light emitting source 11 to emit light. As described above, according to the beauty tool of the sixteenth embodiment, the light emitting source 11 can automatically emit light each time the light projecting unit 15 is operated to move from the previous irradiation area to a new irradiation area. A series of cosmetic treatments can be performed quickly and lightly.

In the sixteenth embodiment, the CMOS image sensor 86 detects the amount of movement of the irradiation case 10, and when the light projecting unit 15 moves to a new irradiation area, a notification signal is emitted with the shift notification structure, and the light source 11 is automatically turned on. However, instead of the sensor 86, the rotation of the shift roller 18 can be used to detect the amount of movement of the irradiation case 10. FIG. For example, a plurality of magnets are embedded in the peripheral surface of the rotating side detent body 28 at regular intervals, and the magnets are turned on when the magnets approach or leave the support frame 19 that supports the fixed side detent body 29 or the main body case 1 . - A reed switch for turning off can be provided, and the shift means 6 can be composed of a magnet, a reed switch, and a shift notification structure. Alternatively, a magnet may be fixed to a magnet holding portion provided on the roller shaft 21 that supports the shift roller 18 or to a magnet holding portion provided within the wall of the shift roller 18, and the reed switch may be turned on and off. . However, when the roller shaft 21 is provided with a magnet, it is supported by the support frame 19 so that the roller shaft 21 can rotate together with the shift roller 18 . When the beauty appliance is used, the reed switch is turned on and off by a magnet in response to the rotation of the rotary-side detent body 28. By measuring the number of turns and activating the shift notification structure, light is projected. After confirming that the unit 15 has moved to a new irradiation area, the light source 11 can automatically emit light. In this case, the magnet may be embedded in only one place on the peripheral surface of the rotating side detent body 28 .

In the fourteenth to sixteenth embodiments, every time the light projecting section 15 is moved by a predetermined amount, the switch for supplying the drive current to the light emitting source 11 is switched to the ON state to automatically turn on the light emitting source 11. I made it glow, but it's not necessary. For example, in a state in which the main body case 1, which has been floating away from the skin surface, is switched to the irradiation posture, the switch that supplies the driving current to the light emitting source 11 is switched to the ON state so that the light emitting source 11 can emit light. There may be. Such a switch structure can be applied to the beauty tools of Examples 1, 5, 7, and 9 to 13, and a switch operation is performed to turn on the light-emitting source 11 when using the beauty tool. Since it is not necessary, it is possible to quickly remove unwanted hair while saving the user's trouble. The shift rotor 18 may be configured using a rubber crawler as a rolling element.
