The LED irradiating body 20 is formed by arranging seven ultraviolet LEDs 21 on a strip-shaped substrate in the same direction and arranging and fixing them in two rows of seven. The six LED irradiators 20 are provided in parallel, and are fixed with the substrate leveled so as to irradiate a downward arm to a hanging arm 41 of a link mechanism described later.
The finger rest 30 is a rectangular plate and is disposed on the lower surface of the opening frame 11 so as to face the irradiation direction of the LED irradiator 20.

  The link mechanism unit 40 includes a drooping arm 41, a horizontal arm 42, a drive arm 43, a worm wheel 44, a worm gear 45, a drive motor 46, and a tension spring 47. As shown in FIG. 2, the drooping arm 41 is formed of an elongated plate bent in a U-shaped cross section, and the opening frame 11 has both end portions facing upward and an intermediate plate portion positioned downward. A portion of about one third from below is fixed to the upper edge of the rotary shaft 41a so as to be rotatable. Six hanging arms 41 are provided, and are arranged at equal intervals in the horizontal direction. As shown in FIG. 2, the horizontal arm 42 is formed by bending both long sides of a rectangular plate upward so as to have a U-shaped cross section, and is rotatably connected to the upper end side of each hanging arm 41. Is done. The drive arm 43 is configured by an elongated plate body whose one end is rotatably connected to the end of the horizontal arm 42. The worm wheel 44 is engaged with the worm gear 45, and the rotation shaft is fixed to the side frame 12 in a cantilever manner. And the other end side of the drive arm 43 is rotatably fixed in the side surface. The worm gear 45 is fixed so as to be rotated by the drive motor 46 and is disposed so as to engage with the worm wheel 44. The drive motor 46 is fixed to the side frame 12 so that the position of the worm gear 45 is an appropriate position. The tension spring 47 is a tension spring having one end fixed to the end of the horizontal arm 42 on the side where the drive arm 42 is not fixed and the other end fixed to the opening frame 11. The connecting portion of the drive arm 43 to the worm wheel 44 rotates according to the rotation of the worm wheel 44. The horizontal arm connected to the drive arm 43 in a state where the connecting portion is located at the uppermost point and the lowermost point. The position of 42 is set to a position where the hanging arm 41 is vertical. Further, the six hanging arms 41 are provided so that the entire width is sufficiently wider than the width where the fingers are lightly opened.

  Next, the usage method and operation | movement of the ultraviolet curable resin hardening apparatus X for nail which has the above structures are demonstrated using FIG. The user inserts the finger F from the opening of the opening frame 11 so as to be substantially parallel to the rotation shaft 41a, and places the finger F on the finger rest 30 so that the nail is positioned under the LED irradiation body 20. In this state, the LED of the LED irradiation body 20 is caused to emit light, and the drive motor 46 is rotated. First, as shown in FIG. 3A, the initial state of the link mechanism portion 40 is that the connecting portion between the drive arm 43 and the worm wheel 44 is at the uppermost point, and the drooping arm 41 is facing directly below. . In this state, the LED irradiator 20 fixed to the hanging arm 41 faces directly below, and as shown in the figure, ultraviolet rays are irradiated directly above the curved surface of the nail. When the worm wheel is rotated clockwise by the drive motor 46 from this state, the drive arm 43 moves so as to push the horizontal arm 42, thereby moving the horizontal arm 42 away from the worm wheel 44. Thereby, the upper side of each drooping arm 41 also moves according to the horizontal arm 42 and rotates around the rotation shaft 41a, and the fixed LED irradiating body 20 is a curved surface of the nail in the drawing as shown in FIG. Each drooping arm 41 is inclined so as to irradiate ultraviolet rays from the upper right of. Further, when the worm wheel 44 rotates, the drive arm 43 moves so as to pull the horizontal arm 42, and the connecting portion between the drive arm 43 and the worm wheel 44 becomes the lowest point as shown in FIG. The arm 41 returns to a position facing directly below. Further, when the worm wheel 44 rotates, the drive arm 43 also moves so as to pull the horizontal arm 42, whereby the horizontal arm 42 moves in a direction approaching the worm wheel 44. As a result, the upper side of each hanging arm 41 also moves according to the horizontal arm 42 and rotates around the rotation shaft 41a, and the fixed LED irradiating body 20 is a curved surface of the nail in the drawing as shown in FIG. Each drooping arm 41 is tilted so as to irradiate ultraviolet rays from the upper left side. Further, when the worm wheel 44 rotates, the drive arm 43 moves so as to push the horizontal arm 42 and returns to the state of FIG.

  By the operation as described above, the LED irradiating body 20 swings around the rotation axis 41a while changing the irradiation direction symmetrically with respect to the direction directly below. As a result, the six LED irradiators 20 irradiate ultraviolet rays while smoothly changing the irradiation direction with respect to the finger rest 30. The nail | claw which has will be irradiated with an ultraviolet-ray directly with respect to the arbitrary surfaces on a curved surface. In addition, since the LED irradiating body 20 is provided with a plurality of ultraviolet LEDs 21 in the front-rear direction, the nails are irradiated with ultraviolet rays if they are within a certain range in the front-rear direction. That is, since it is sufficient that the nail placement range is within a certain range, restrictions on the nail placement location can be reduced.

In addition, the number of LED irradiation parts 20, the number of LED provided in LED irradiation part 20, and arrangement | positioning can be suitably changed according to the number of the nail | claw to apply, the magnitude | size of the user's hand assumed, etc. . Moreover, when using the thing with a small irradiation angle of LED provided in the LED irradiation part 20, two or more LED irradiation parts 20 are provided, or 2 LED arrange | positioned in the direction orthogonal to the rotating shaft of the LED irradiation part 20 is provided. It is desirable to provide the above width. In the former case, as shown in the operation diagram of the LED irradiation unit 20A in the case where the LEDs of FIGS. 4A to 4C are arranged in a line, by providing a plurality of LED irradiation units 20A, the LED irradiation units 20A are provided between the LED irradiation units 20A. If a nail | claw is located, even if the irradiation angle from LED is narrow, it can irradiate to the both sides of the curved surface of a nail | claw by irradiating LED from both right and left directions. In the latter case, as shown in the operation diagram of the LED irradiation unit 20B in which the LEDs of FIGS. 5A to 5C are arranged with a plurality of widths, even if the nail is positioned directly below the LED irradiation unit 20B, the LED irradiation By tilting the portion 20B, it is possible to irradiate ultraviolet rays from both sides of the curved surface of the nail by the LEDs 21a2 and 21a2 existing on both ends.
Furthermore, regarding the mechanism for moving the LED irradiation unit 20 far, the above-mentioned link mechanism unit is an example, and various changes can be made.
