Moving. At least one pair (two pieces) of contactors is preferably provided, and two pairs (four pieces) are more preferably provided. Also, a plurality of cam followers may be provided corresponding to each of the plurality of cam grooves. For example, when increasing the number of contacts with the skin surface from four to six or eight, it is preferable to double the annular cam grooves to increase the number of contacts.

Further, the contacts 3a, 3b, 3c and 3d have a first surface S1, a second surface S2, a third surface S3 and a fourth surface S4 that come into contact with the user's skin. It is preferable that the first surface S1, the second surface S2, the third surface S3, and the fourth surface S4 have surfaces having a large frictional force against the user's skin surface. The first surface S1, the second surface S2, the third surface S3, and the fourth surface S4 can be made of materials such as silicone rubber and gel pads. Moreover, you may have an adhesive layer.

In addition, in the present embodiment, the first surface S1, the second surface S2, the third surface S3, and the fourth surface S4 are circular in plan view, but may be any shape such as a rectangle or an oblong shape. can be done. Further, the materials, shapes, etc. of the first surface S1, the second surface S2, the third surface S3, and the fourth surface S4 may be different from each other. Furthermore, depending on the site to be treated, the condition of the skin, etc., the contactor may be replaced with another contactor having a desired shape and material for the surface that contacts the skin, thereby stretching the skin more stably. be able to.

The sizes of the first surface S1, the second surface S2, the third surface S3, and the fourth surface S4 are not particularly limited. , preferably from 1.5 mm to 5.0 mm in diameter.

The driving source 5 drives the first rotating shaft 50 to rotate the disk-shaped cam 2 fixed to the second rotating shaft 20 via the first transmission gear 6 and the second transmission gear 7 . The drive source 5 may be, for example, an electric motor. The number of revolutions of the driving source 5 can preferably be arbitrarily set according to the location and condition of the skin surface to be treated, and can be, for example, 20 to 60 rpm. Further, the drive source 5 is connected to a power supply source such as a rechargeable battery, a dry battery, or a commercial power source.

The cover 9 has a circular shape that covers the disk-shaped cam 2 and is fitted to the substrate 8 . The cover 9 has elongated insertion holes 9a, 9b, 9c and 9d formed along the moving directions L1, L2, L3 and L4 of the contacts at positions corresponding to the contacts 3a, 3b, 3c and 3d. there is As shown in FIG. 2, contacts 3a, 3b, 3c, and 3d are inserted through the respective insertion holes, and are movably fixed within the insertion holes 9a, 9b, 9c, and 9d. Further, as shown in FIG. 3, the contactors 3a, 3b, 3c, and 3d are restricted from moving in the rotation direction R of the disk-shaped cam 2 by the insertion holes 9a, 9b, 9c, and 9d. As shown in FIGS. 1 and 3, the cam followers 31a, 31b, 31c, and 31d are held by the bottom surface of the cam groove 21 (the end surface of the cam groove 21 in the Y-axis direction) and the cover 9. As shown in FIGS.

With this structure, for example, the cover 9 can be removed to replace the contacts 3a, 3b, 3c, and 3d, or the disc-shaped cam 2 and the contacts 3a, 3b, 3c, and 3d can be replaced together as described later. The number of contacts can be varied to provide different extension patterns.

Next, the movement of the contacts 3a, 3b, 3c and 3d (the shape of the cam grooves 21) will be described.

The cam groove 21 is, for example, an annular shape along the circumference of the disk-shaped cam 2, and has a first diameter of the disk-shaped cam 2 and a second diameter perpendicular to the first diameter. It has a wavy shape in which four protruding portions 211, 212, 213, and 214 are provided at equal intervals. With this shape, the contacts 3a, 3b, 3c, and 3d can be reciprocated in four directions (radial directions) about an arbitrary point on the skin surface of the user parallel to the skin surface. Therefore, the skin can be stably stretched without the contactors 3a, 3b, 3c, and 3d in contact with the skin being separated from the skin. In addition, since it can be radially expanded and contracted in four directions, it is possible to give stimulation to the skin by repeating two-dimensional expansion and expansion release (contraction) in the radial direction.

In this embodiment, an example of repeating extension and contraction in four directions has been shown, but the direction of extension and contraction can be selected by, for example, changing the number and positions of the convex portions.

The contacts 3a, 3b, 3c, and 3d are positioned, for example, on the first diameter of the disk-shaped cam 2 with the second rotating shaft 20 interposed therebetween, and are perpendicular to the first diameter. The contacts 3b and 3d are arranged on the second diameter to sandwich the second rotating shaft 20. As shown in FIG. The cam followers 31a, 31b, 31c and 31d of the contacts 3a, 3b, 3c and 3d are similarly arranged and engaged with the cam grooves 21, respectively. As the disk-shaped cam 2 rotates, the cam followers 31a, 31b, 31c, and 31d move. Based on the movement of the cam followers 31a, 31b, 31c, and 31d, the contacts 3a, 3b, 3c, and 3d move in the moving direction L1. , L2, L3, and L4. In other words, the contacts 3a, 3b, 3c, and 3d are parallel to the user's skin surface and can reciprocate in four directions (radial directions) around an arbitrary point on the skin surface. Specifically, the contacts 3a and 3c can move in the Z-axis direction, and the contacts 3b and 3d can move in the X-axis direction simultaneously on the same plane in directions away from each other or in directions toward each other. Therefore, as shown in FIG. 5, by bringing the contacts 3a, 3b, 3c, and 3d into contact with the user's skin, the contacts 3a, 3b, 3c, The skin can be stretched stably without the 3d separating from the skin. Furthermore, it is possible to give a stimulus that repeats two-dimensional extension and contraction (pinch) of the user's skin centering on an arbitrary point on the user's skin. In FIG. 5, the contact 3a moves in the direction perpendicular to the plane of the paper (towards the front and the back of the plane of the paper), and the contacts 3b and 3d move in the left-to-right direction of the plane of the paper.

Further, since the contacts 3a, 3b, 3c, and 3d can all be moved along the skin surface, the beauty tool 1 is held stationary against the skin surface, and the disk-shaped cam 2 is rotated. As a result, the skin surface can be stimulated by repeated stretching and contraction (pinch).

In the case of this embodiment, the contact between the cam groove 21 and the cam followers 31a, 31b, 31c, and 31d is schematically assumed to be a sliding contact. , 31b, 31c, and 31d can make sliding contact with each other by reducing the coefficient of friction. In order to reduce the friction between the cam groove 21 and the cam followers 31a, 31b, 31c and 31d, rolling friction may be used, or the cam followers 31a, 31b, 31c and 31d may be formed of bearings.

The shape of the cam grooves 21 is not limited to the shape and number of cam grooves exemplified in this embodiment, and can be changed as appropriate according to the intended stimulus, and the stretching method (rhythm, pattern) can be controlled with a simple configuration. . For example, if the range of extension is to be widened, the amplitude of the waveform can be increased, and if the range of extension is to be decreased, the amplitude can be decreased. For this purpose, for example, a disk-shaped cam having a desired cam groove and a plurality of contactors assembled with a plurality of cam followers inserted into the cam groove are set, the cover 9 is removed, and a disk-shaped cam is formed. Replace the set of cams and contacts. This makes it possible to provide beauty instruments 1 with different extension methods.

In the case of FIG. 1, the cam groove 21 has a wavy shape in which four protrusions 211, 212, 213, and 214 protruding toward the circumference are provided on a circular groove at regular intervals. However, for example, the basic shape of the cam groove can be an elliptical groove. In the case of this elliptical groove, when four cam followers 31a, 31b, 31c, and 31d are inserted at intervals of 90° with respect to the center of the second rotating shaft 20, the disk-shaped cam 2 rotates to generate four grooves. When a pair of contactors among the contactors moves from the major axis direction to the minor axis direction of the ellipse relative to the cam groove, it becomes a pinching operation, and the other pair moves relatively from the minor axis direction to the minor axis direction. When it moves in the axial direction, it becomes an extension motion. Therefore, the direction orthogonal to the direction of pinching motion is stretching motion, and stretching and contraction can be applied to the skin surface at the same time.
