FIG. 1 to FIG. 8 show an example of an embodiment for carrying out the present invention. FIG. 1 is a view showing the entire skin beautifying device D. FIG. 2 is a front view panel 1a of the infrared facial device 1 in front. FIG. 3 is a diagram showing a state viewed from the front after removing the lens, FIG. 3 is a diagram showing a state in which the infrared facial device 1 represented by a cross-sectional view along the line AA in FIG. 2 is brought close to the face, and FIG. It is a figure which shows the state which made the part 4 contact | abut on the face.

  FIG. 5 is an enlarged cross-sectional view of the state in which the laser irradiation unit 4 is viewed from the side, and FIG. 6 is a side view of the state in which the laser irradiation unit 4 is in contact with the skin Y of the human body and is irradiated with the laser beam L. FIG. 7 is a schematic diagram showing the relationship between the components inside the laser irradiation unit 4 and the laser beam L, FIG. 7 is an enlarged view taken along the line BB in FIG. 6, and FIG. It is a figure which shows the process at the time of irradiating the skin Y of a human body with the laser beam L.

  The skin beautifying device D includes a laser irradiation unit 4, an infrared facial device 1, and a control box 10 in which these devices are electrically connected via first and second cables 31 and 32 (control device of the present invention). The infrared facial device 1 and the control box 10 mainly constitute an infrared irradiation device E, while the laser irradiation unit 4 and the control box 10 mainly constitute a laser irradiation device F. The control box 10 is supplied with current from a household power supply via a power cable 33 to a power supply circuit (not shown) provided in the control box 10.

  In addition, a television receiver 35 (display device of the present invention) is electrically connected to the control box 10 via a third cable 34. At both ends of each of the first, second, and third cables 31, 32, and 34, these cables 31, 32, and 34 are connected to the laser irradiation unit 4, the infrared facial device 1, and the television receiver 35 and the control box. Connection plugs (not shown) for detachably connecting to 10 are respectively attached. The connection plugs at one or both ends of at least one of the cables 31, 32, and 34 are omitted as necessary, and the omitted ends are directly attached to the respective devices so as not to be detachable. You may make it connect.

  Further, on the front surface of the control box 10, a power switch 36 for energizing or cutting off the current from the household power source through the power cable 33 and the current from the power circuit for irradiating infrared rays are used for the infrared beauty. An infrared irradiation selection switch 6 for energizing or interrupting the device 1 is provided. An infrared switch 15 is provided on the front face of the infrared facial device 1 to energize or cut off the current supplied from the power supply circuit to the infrared facial device 1 to the power supply unit such as the infrared light source 2b of the infrared facial device 1. Is provided.

  Furthermore, the front face of the control box 10 is irradiated with a laser beam L selection switch 37, a stain irradiation selection switch 38, so that the output of the laser beam L can be appropriately selected according to the skin condition of the human body. When equipped with an acne irradiation selection switch 39, a pore irradiation selection switch 40, and a live hair irradiation selection switch 41, when the laser irradiation unit 4 is used, among these switches 37 to 41 (irradiation mode selection means of the present invention) Any one switch is selected and operated. In the vicinity of the selection switches 37 to 41 on the front surface of the control box 10, a guidance display (not shown) that briefly explains the functions of the selection switches 37 to 41 is attached. For each of these selection switches 37 to 41, which of the five laser light sources 4a to 4e (see FIGS. 5 and 6) to be described later is to be energized and the laser beam of the energized laser light source. An irradiation mode associated with the output level is set in advance.

  Therefore, the user simply sees the guidance display in the vicinity of each of the selection switches 37 to 41 of the control box 10 and selects and presses the desired selection switch, and the irradiation method corresponding to the selection switch is automatically selected. Therefore, the setting operation of the irradiation method is extremely easy.

  The adjustment of the output of the laser beam L is performed by increasing or decreasing the voltage in a state where the duty ratio between the energization time and the interruption time of the current pulse when energizing the laser irradiation unit 4 from the power supply circuit is kept constant. . That is, the voltage is set so that the output becomes a predetermined output by increasing the voltage to increase the output of the laser beam L and decreasing the voltage to decrease the output. Is done. Accordingly, the output of the laser beam is preset for each of the selection switches 37 to 41. Instead of this output adjustment method, a method of adjusting the duty ratio while keeping the voltage level constant may be employed.

  The power switch 36, the infrared switch 15, and the selection switches 6, 37 to 41 are push button switches each having a light emitting diode (not shown) disposed therein. Each time the switch 36 is pressed, power is supplied from the power supply circuit in the control box 10 to the infrared facial device 1 and the laser irradiating unit 4, and every time the infrared irradiation selection switch 6 is pressed, power is supplied to the infrared facial device 1 and infrared rays. Each time the switch 15 is pressed, a state in which energization to the infrared light source 2b and the like in the infrared facial device 1 is allowed and prohibited is alternately performed repeatedly. While the light emitting diode is turned on, the light emitting diode is turned off when the light emitting diode is in a prohibited state, so that the energized state can be easily recognized with the naked eye.

  Each of the selection switches 37 to 41 is in a state where any one of these switches is pressed (selected state) (this is a first-pressed selection switch). When any one of the selection switches other than the first push selection switch (this is used as the second push selection switch) is pressed, the selection of the first push selection switch is automatically released, and the light emitting diode of the selection switch Is turned off, while the light-emitting diode of the push selection switch is turned on. When the selected switch among the selection switches 37 to 41 is pressed again, the selection of the switch is released and the light emitting diode of the switch is turned off.

  In addition, the laser irradiation unit 4 and the infrared facial device 1 are electrically connected to one control box 10 via the first and second cables 31 and 32, respectively. Can be used at the same time, so that when one of the two users is using the infrared irradiation device E, the other user can use the laser irradiation device F. it can. For this reason, it is not necessary to provide the control apparatus for both apparatuses separately, and the skin beautifying apparatus D can be provided at low cost.

  In addition, one user uses the infrared facial beauty device 1 to irradiate the part of the human body to be subjected to the skin treatment with infrared rays in advance, and then irradiate the part with the laser beam by the laser irradiation unit 4. Thus, after the part of the human body is warmed to some extent by the thermal effect of the infrared irradiation, the laser beam is subsequently applied to the part of the human body. Therefore, even if the output of the laser beam is relatively low Sufficient skin treatment can be performed.

  In this way, various types of irradiation can be easily selected by a simple operation of appropriately selecting the six selection switches 6, 37 to 41 provided in one control box 10.

  As shown in FIG. 1, the infrared facial device 1 is provided with an infrared irradiation unit 2 that emits infrared rays through a window 3. In addition, as shown in FIG. 2, a pair of left and right guide shafts 11a and 11b (guide members of the present invention) are fixed in the infrared facial device 1 so that the longitudinal direction thereof is along the vertical direction. The support shafts 2a and 2a provided at both ends of the infrared irradiation unit 2 are respectively held by the guide shafts 11a and 11b. The support units 2a and 2a are guided by the guide shafts 11a and 11b and are irradiated with the infrared irradiation unit 2. Is moved in the vertical direction (in the direction of the broken line arrow shown in FIGS. 1 and 2) by a driving device (not shown). In this way, when irradiating infrared rays over a wide area of the human skin, it is only necessary to maintain the posture while the part of the human body to be irradiated is positioned in the vicinity of the infrared irradiation unit 2 of the infrared facial device 1. Irradiation work becomes easy.

  The front panel 1a of the infrared facial device 1 has a long hole-shaped notch so that the support portions 2a, 2a at both ends of the infrared irradiation unit 2 can move in the vertical direction while being guided by the guide shafts 11a, 11b. Portions 1b and 1b are formed.

  As shown in FIG. 3, the infrared irradiating section 2 is pivoted on the support sections 2a and 2a so as to be swingable in the vertical direction around the support shafts 14 and 14 provided on the support sections 2a and 2a, respectively. It is supported.

  Further, an infrared light source 2b is provided at the front end of the infrared irradiation unit 2, and a roller 12 is provided at the rear end. The roller 12 has a wave of a plate 13 whose one side surface is formed into a wave shape. The roller 12 is in contact with the shape portion 13a, and the roller 12 moves along the wave shape portion 13a of the plate 13 as the infrared irradiation portion 2 moves in the vertical direction. The infrared irradiation unit 2 swings in the vertical direction at an angle of.

  For this reason, as a result of the change in the irradiation angle of the infrared ray irradiated from the infrared light source 2b of the infrared irradiation unit 2 (see FIG. 3), the surface of the human body (for example, the face) has a relatively large undulation and small unevenness such as skin wrinkles. It is possible to irradiate infrared rays uniformly and reliably without remaining in every corner. Thereby, a sufficient thermal effect can be obtained for wrinkles such as the face, tarmi, and the like.

  Next, the laser irradiation unit 4 will be described in detail with reference to FIGS. The laser irradiation unit 4 emits a laser beam L having a wavelength of around 780 nm (nanometers) and five laser light sources 4a to 4e having the same light emission characteristics, and light emitted from these laser light sources 4a to 4e. Two lenses 42 a and 42 b for focusing the laser beam L and the imaging device 16 are provided. The imaging device 16 is composed of a solid-state imaging device such as a charge coupled device sensor (CCD) or a complementary metal oxide semiconductor (CMOS).

  As shown in FIGS. 6 and 7, the five laser light sources 4a to 4e are arranged in a line so as to be substantially along the direction in which the surfaces of the lenses 42a and 42b spread.

  Further, the laser irradiation unit 4 is provided with a push button type laser irradiation switch 5 in the vicinity of the holding unit 7 held by the user, and the user operates the laser irradiation switch 5 while holding the holding unit 7 with one hand. can do. When the switch 5 is pressed, the output of the laser beam L emitted from any of the laser light sources 4a to 4e is switched from a predetermined low output lower than the output during the skin beautifying operation to a predetermined high output during the skin beautifying operation.

  Moreover, when the laser irradiation part 4 is made to contact | abut the skin Y of the human body at the edge part on the opposite side to the holding part 7 of the laser irradiation part 4, it detects that the laser irradiation part 4 contacted the skin Y. A contact sensor 8 (contact detection means of the present invention) is provided, and a detection signal of the contact sensor 8 is transmitted to a controller (not shown) provided in the control box 10. When the controller receives the detection signal from the contact sensor 8, the controller automatically emits a laser beam from any of the laser light sources 4a to 4e of the laser irradiation unit 4, while the laser irradiation unit 4 is detached from the skin Y of the human body. Thus, when the detection signal of the contact sensor 8 is interrupted, the emission of the laser beam is automatically stopped. For this reason, laser beams are not unnecessarily emitted from the laser light sources 4a to 4e.

  On the other hand, the enlarged image captured by the imaging device 16 can be visually confirmed on the screen of the television receiver 35. For this reason, it is possible to easily and surely irradiate the part to be irradiated while confirming the state of the skin on the screen of the television receiver 35.

  Further, when the skin light Y emitted from the laser light sources 4a to 4e irradiates the skin Y of the human body with the predetermined output lower than the output during the skin beautifying operation, the irradiated skin region is imaged. The part imaged by the apparatus 16 and irradiated with the laser beam L is displayed in a color that can be identified on the screen of the television receiver 35 with respect to other parts not irradiated.

  For this reason, it is possible to irradiate with the laser beam L having an output lower than that at the time of the skin beautifying operation, and to confirm the irradiated human body part by the television receiver 35. Before, it is possible to position the laser irradiation unit 4 at the site to be irradiated accurately and easily while confirming in advance the portion of the human body to which the laser beam L is irradiated by the television receiver 35. As a result, it is possible to accurately and surely irradiate only the portion to be irradiated with the laser beam with the predetermined high output during the skin beautifying operation.

  When the skin beautifying device D configured as described above is used, first, the control box 10 to which the infrared beauty device 1, the laser irradiation unit 4 and the television receiver 35 are connected is connected to a household power supply via the power cable 33. After the connection, the power switch 36 of the control box 10 is turned on.

  Next, when using the infrared facial device 1, the infrared irradiation selection switch 6 provided on the front surface of the control box 10 is pressed and turned on, and infrared rays are transmitted from the power supply circuit in the control box 10 through the second cable 32. Power is supplied to the facial device 1. Next, when the infrared switch 15 provided on the front panel 1a of the infrared facial device 1 is turned on, infrared rays are emitted from the infrared light source 2b of the infrared irradiation unit 2, and the infrared irradiation unit 2 swings in the vertical direction while moving up and down. Move in the direction. At this time, when a face or the like is brought close to the infrared irradiation unit 2, a thermal effect can be sufficiently obtained for wrinkles or tarmi on the face or the like.

  When the use of the infrared facial device 1 is finished, the infrared switch 15 is pressed again to turn it off.

  On the other hand, when the laser irradiation unit 4 is used, the human body to be irradiated with the laser beam L after appropriately selecting and pressing any one of the selection switches 37 to 41 provided on the front surface of the control box 10. The laser irradiation unit 4 is brought into contact with the part. Then, a detection signal from the contact sensor 8 of the laser irradiation unit 4 is transmitted to the controller in the control box 10, and in advance according to the irradiation mode corresponding to one of the selection switches 37 to 41 that has already been selected. A laser beam is automatically emitted from any of the laser light sources 4a to 4e of the determined laser irradiation unit 4. The laser beam emitted at this time is emitted at a predetermined output lower than the output during skin beautification work. The user observes an enlarged image of the part projected on the screen of the television receiver 35, and the laser irradiation unit 4 so that the part to be irradiated with the laser beam L coincides with the irradiation position of the laser beam L currently irradiated. Is positioned with respect to the human body.

  When the positioning is completed, the laser irradiation switch 5 of the laser irradiation unit 4 is pressed again to switch the output of the laser beam L emitted from any one of the laser light sources 4a to 4e to a predetermined high output during skin beautifying work. As a result, laser beam irradiation (irradiation during skin-beautifying work) is started with a predetermined output corresponding to the irradiation mode. When the laser irradiation switch 5 is pressed, the irradiation time of the laser beam is measured by a timer device (not shown) provided in the control box 10, and when a preset set time has elapsed, the laser irradiation unit The output of the laser beam emitted from any one of the four laser light sources 4a to 4e at the time of skin beautification is automatically switched to a predetermined low output lower than the output. For this reason, when it is desired to subsequently irradiate another part of the human body with the laser beam, the user can quickly move to the positioning operation of the laser irradiation unit 4 performed while looking at the screen of the television receiver 35. In addition, when the laser irradiation unit 4 is detached from the skin Y of the human body before the set time elapses and the detection signal of the contact sensor 8 is interrupted, the irradiation of the laser beam is stopped. The measurement of the timer device is reset.

  6 and 7 show a state in which only the laser light sources 4b, 4c and 4d are energized corresponding to the irradiation mode of the selected selection switch, and the laser beam L is emitted only from these laser light sources. ing.

  When it is desired to irradiate the laser beam L over a wide area of the skin Y of the human body, as shown in FIG. 8, after irradiating the irradiation region R1 first and completing the irradiation process, the irradiation position of the laser irradiation unit 4 is determined. The irradiation regions R2 and R3 are subsequently irradiated with a shift. At this time, since the laser irradiation unit 4 is provided with five laser light sources 4a to 4e, if at least two or more laser light sources are used for simultaneous irradiation, even if one irradiation is performed, a certain amount is obtained. The laser beam L can be applied to a skin area having a large area. For this reason, irradiation work can be performed efficiently and irradiation unevenness (shaded portion in FIG. 8) can be reduced as compared with the conventional irradiation step shown in FIG.

  When the use of the laser irradiation unit 4 is temporarily interrupted, the laser irradiation unit 4 in contact with the user's skin is detached from the user's skin Y. Thereby, the detection signal of the contact sensor 8 of the laser irradiation unit 4 is interrupted, and the emission of the laser beam is automatically stopped. When resuming use of the laser irradiation unit 4, the laser irradiation unit 4 is brought into contact with the skin Y of the user again. Then, the detection signal of the contact sensor 8 is transmitted to the controller in the control box 10, and a predetermined low output laser beam lower than the output during skin beautifying work is emitted from the laser irradiation unit 4. Thereafter, when the laser irradiation switch 5 is pressed again, the laser irradiation switch 5 is switched to a predetermined high-power laser beam during skin beautifying work.

  Further, as another method for temporarily interrupting the use of the laser irradiation unit 4, the selected selection switch may be pressed again to cancel the selection of the selection switch. When the use of the laser irradiation unit 4 is completely terminated, the power switch 36 is pressed again to turn it off.

  In the present embodiment described above, the five laser light sources 4a to 4e are arranged in a line so as to be substantially along the direction in which the surfaces of the lenses 42a and 42b spread, but at least two laser light sources are arranged in a line. It is enough to arrange. Further, three or more laser light sources may be arranged in a plurality of rows so as to be substantially along the direction in which the surfaces of the lenses 42a and 42b spread. Thus, when laser beams are simultaneously irradiated from a plurality of laser light sources, it is possible to irradiate a wider area of the skin with a single irradiation. For this reason, irradiation work can be performed more efficiently and irradiation unevenness can be further reduced.

  In the present embodiment, for each of the selection switches 37 to 41, which of the laser light sources 4a to 4e is energized (selection of the laser light source) and the laser beam of the laser light source to be energized is selected. The irradiation mode is set in advance in association with both the output level (laser beam output), but instead of “selection of laser light source” or “laser beam output” The irradiation mode may be set in advance in association with only one of them.

  In the present embodiment, when the preset time has elapsed from when the laser irradiation switch 5 of the laser irradiation unit 4 is pressed, the timer device in the control box 10 is activated to output the laser beam. In addition to being able to switch from a predetermined output during skin beautification to a predetermined low output lower than the output, in addition to this, a second timer device is provided separately, and by setting the time of the timer device, The user may arbitrarily set the irradiation time of the laser beam by the output during the skin beautifying operation. In addition to such a method, the irradiation time may be set in advance in association with the type of each of the irradiation selection switches 37 to 41.

  In the present embodiment, the infrared irradiation unit 2 is energized from the power circuit in the control box 10 by pressing the infrared irradiation selection switch 6 and pressing the infrared switch 15 of the infrared facial device 1. Although it comprised so that the operation | movement of the infrared irradiation part 2 might be started, it replaces with this and the sensor which detects that a human body approached the infrared facial device 1 is provided, and operation | movement of the infrared irradiation part 2 is carried out with the detection signal of this sensor. You may make it start.

  Furthermore, in the present embodiment, the infrared irradiation unit 2 is moved in the vertical direction by being guided by the guide shafts 11a, 11b arranged in the vertical direction, but instead, the guide member is moved in the horizontal direction. The infrared irradiating unit 2 may be moved in the left-right direction while being guided by the guide member.
