By applying the layout shown in FIG. 9, the energy focal position R2 of the laser beam and, more Nag may overlap on the skin surface S, which is on the skin surface S over the focal position R2, it is again dissipated will be reduced laser beam density is irradiated, safety when performing treatment is ensured.

[0048] Further, as shown in FIG. 10, Tsutsujo member 52 while resisting the urging force of the coil spring 51, retracts the arrow Z2 direction, the cylindrical member 52 detects that it has moved to the retracted position the detection switch 56 may be provided. This as the detection switch 56, such as a push switch which is placed in contact with for example the rear end portion of the tubular member 52 which has moved to the retracted position is shown an example. Furthermore, in this case, in a state where movement is not detected in the detection switch 56 to the retracted position of the tubular member 52, CPU 31 and the laser drive as the light irradiation inhibiting means for inhibiting the drive of which constitute the laser light irradiation mechanism e.g. Rezadaio de 20 it may be caused to function circuit 30 (see FIG. 7). The detection result by the detection switch 56, in response to Chikaraina crab which means that the tubular member 52 is retracted to a retracted position, to add a moving system Gosuru mechanism shielding member 55a, thereby, the laser irradiation port 23 It is also possible to control the opening and closing of the not good. By using the detection switch 56 in such a form, it is this the user to more reliably prevent the irradiation of unintended laser beam.

[0049] Further, in place of the head portion 22 of the cylindrical shape shown in FIG. 4 etc., as shown in a perspective view and a plan view of FIG. 12 in FIG. 11, rectangular having the same function as the tubular member 52 the tubular member 62 may be applied to the head portion 61 of the tubular force such as the pedestal 64 is also a rectangular cross section (rectangular). The head portion 61 of this, for example, a rectangular hole (elongated hole of the square) is provided as a laser irradiation port 63. Further, the head unit 61 so as to surround the laser irradiation port 63 from the periphery, at least three or more contacts 65a to realize Tatsuchise capacitors function, 65b, 65c are located.

[0050] Here, the internal structure of the head portion 61, in addition to FIGS. 11 and 12, perform the described based on FIG. 13. Incidentally, FIG. 13 is a perspective view for schematically showing a built-in optical system head portion 61.

[0051] That is, the between the lasers irradiation port 63 at the tip of the laser diode 20 and a head portion 61 which is incorporated in the head portion 61 (the optical path of the laser beam emitted from the laser diode 20), the vertical lateral ratio lens 24b of the barrel shape for different laser spot Q is formed on the skin surface S having is arranged. The shape of the incident surface and the exit surface of the laser beam in the lens 24b is the curvature of the vertical and horizontal are formed by bulging differently. Specifically, in FIG. 13, a lens 24b illustrated in a standing posture along the arrow Y1- Y2 direction, the curvature of the horizontal cross section of the inlet elevation portion and the exit portion of the laser beam, than the curvature of the vertical section I increases are sea urchin formation. That is, the lens 24b is the laser beam emitted to the laser irradiation port 63 side while changing the aspect ratio of the cross-sectional shape of the les one The light incident from the laser diode 20 side.

[0052] The laser irradiation port 63 described above, the shape and capable of passing all of the light beam Guso such that blocking the shape (laser beam to correspond to the aspect ratio of the laser beam cross-sectional shape passing through the lens 24b are formed by elongated rectangular hole) having a size. That is, Rezasupo Tsu preparative Q to form on the skin surface S lasers light passes through the lens 24b and the laser irradiation port 63, as shown in FIG. 11 one 13, the longitudinal direction of the laser irradiation port 63 (arrow Y1 - Y2-way direction) becomes the major axis, while the lateral direction (arrow X1-X2 direction) is long narrow that Do and the minor axis of the laser irradiation port 63, the radiation spot.

[0053] Thus, in the minor axis direction of the laser spot Q formed on the skin surface S (arrow XI- X2-way direction), the head portion 61 by the user moves, treatments for skin surface S (lasers light Granting thermal action) by irradiating can be performed efficiently. Further, instead of placing the lens 24b for forming the elongated lasers spot, for example, it may be arranged a plurality of lasers diodes. In this case, the plurality of laser diodes, Les monodentate provided to the irradiation port 63 and a position opposed to, and be arranged side by side in a direction along the longitudinal direction of the laser irradiation port 63 is desirable. Further, FIG. 11, in place of the head portion 61 to that shown in such FIG. 12, as shown in the plan view of the perspective view and FIG. 15 in FIG. 14, the tubular member 72 and the pedestal 74 of the cross-section substantially positive rectangular, and a rectangular laser irradiation port 73, a lens 24c of barrel shape, and the contact 75a, 75b, may constitute a treatment unit by applying the head portion 71 with a 75c. By the head portion 71 can be expected substantially the same effects as those of the head unit 61 described above. Industrial Applicability
