Description

  The present invention relates to a photo-hair dyeing device used when hair is dyed using light.

  Conventionally, as a method of dyeing (dying) hair, a method of applying various hair dyes such as an oxidative hair dye to the hair and coloring the hair by using a chemical change thereof is known. In recent years, a technique for photo-hair dyeing that dyes hair using light has been developed.

  This photo-hair dyeing technique is a method of applying a photo-hair coloring agent (for example, a photosensitive acid hair dye) containing a specific substance (for example, silver salt) that reacts with light to develop color, and then applying sunlight or hair to the hair. Color is developed by applying light from a fluorescent lamp (specifically, ultraviolet rays) (see Patent Document 1).

JP 2008-69131 A

  However, in the technique of Patent Document 1, since hair is dyed by sunlight or light from a fluorescent lamp, the light irradiation state, such as the intensity of light and from which direction the light is irradiated, is not stable, and hair is not easily dyed. There was a problem of uneven hair dyeing.

In particular, among the hairs on the head, it is difficult for light to hit the inner hair, so there is a problem that the hair dyeing is slow and the unevenness of the hair dyeing is large.
The present invention has been made in view of these problems, and an object of the present invention is to provide a photo-hair dyeing apparatus capable of quick and non-uniform photo-hair dyeing.

It is characterized by that.

  In the present invention, based on the change in the state of the light received by the light receiving sensor, the state of the hair dye is determined, and the result of the determination of the state of the hair dye is, for example, sound, voice, light ( Since notification is made to the user or the like using light for notification, which is different from the light for hair dyeing), vibration, and the like, it is possible to realize light hair dyeing that is quicker and more uniform than in the past.

(2) The invention of claim 2 is characterized in that the light emitting mechanism is a plate shape, a brush shape in which a large number of pins are erected, or a comb shape having a large number of comb teeth.
The present invention exemplifies a preferable structure of the light emitting mechanism.

(3) The invention of claim 3 includes a first member and a second member sandwiching the hair, and the light emitting mechanism is provided on a side of the first member facing the hair.
In this invention, since light is irradiated in the state which pinched hair, photo-hair dyeing can be performed efficiently.

(4) The invention of claim 4 is characterized in that a reflection portion for reflecting the light emitted from the light emitting mechanism is provided on the surface of the second member facing the first member.
In this invention, since the reflection part which reflects light facing the light emission mechanism is provided, light can be efficiently irradiated with respect to hair. Therefore, it is possible to carry out photo hair dyeing more effectively.

(5) The invention of claim 5 is characterized in that when the state of hair dyeing is determined by the control unit, the state of light emitted from the light emitting unit is controlled based on the state of hair dyeing. And
In the present invention, since the degree of light irradiation (light quantity, etc.) is controlled in accordance with the state of hair dyeing, hair can be dyed without unevenness.

  (6) According to the invention of claim 6, the light receiving sensors are arranged at a plurality of locations on the side facing the hair, and the light emitting portions are arranged at a plurality of locations, and the dyes are dyed depending on the position by signals from the light receiving sensors. When it is determined that there is unevenness in the state of the hair, control is performed so as to change the state of the light emitted from each light emitting unit so as to make the hair dye uniform.

  In the present invention, when the hair dyeing state is uneven depending on the position of the hair (for example, the position of the hair on the head), the light irradiation state (light quantity, etc.) is controlled according to the position so that there is no unevenness. Therefore, it is possible to carry out hair dyeing without unevenness.

  (7) The invention according to claim 7 irradiates from each light emitting part so that the light emitting part is arranged at a plurality of locations on the side facing the hair, and the state of hair dyeing at each position of the hair dyeing target is different. Control is performed so as to change the state of the light to be emitted.

  In the present invention, by using a plurality of light emitting portions, for example, only hair at a desired position can be dyed with respect to the hair on the head. Therefore, various displays (depending on the degree of hair dyeing) can be performed by the hair on the head.

(8) The invention of claim 8 is characterized in that an imaging member (for example, an optical fiber) for photographing the scalp or hair is provided on the side facing the hair.
Thereby, the state of a scalp and hair can be visually recognized using the camera and monitor connected to the optical fiber, for example. Therefore, for example, when the degree of hair dyeing is not sufficient, it is possible to promote hair dyeing by increasing the amount of light irradiation at a desired location.

  Embodiments to which the present invention is applied will be described below with reference to the drawings.

a) First, the structure of the photohair dyeing apparatus of a present Example is demonstrated.
As shown in FIG. 1, the photohair dyeing device 1 of this embodiment is a brush-like device, in which a number of plastic pins 5 for scooping hair are formed on a plastic columnar body 3. It is.

  Specifically, the main body 3 has a shape in which the distal end portion 7 has a wide plate shape and the handle portion 9 becomes narrower toward the root side, and one side of the distal end portion 7 (that is, the pin 5 is formed). The plate-like light-transmitting substrate 11 made of a transparent plastic capable of transmitting light is formed on the light-transmitting side.

  Further, the pin 5 is also made of a transparent plastic capable of transmitting light, and the translucent substrate 11 protrudes perpendicularly to the translucent substrate 11 on one surface (outer surface) of the translucent substrate 11. It is formed integrally with the substrate 11.

In addition, the pin 5 and the translucent board | substrate 11 are called the translucent part 13, and the said main body 3 is comprised with the material which does not permeate | transmit light except the translucent part 13. FIG.
Further, as shown in FIG. 2B, in the main body 3, a light emitting unit that irradiates light to the translucent substrate 11 so as to be in contact with the side of the base side of the translucent substrate 11 (left side in the figure). 17 is attached. The light emitting unit 17 is a device that irradiates light having a wavelength capable of photodyeing (specifically, light including ultraviolet rays), and a fluorescent lamp, an LED that generates ultraviolet rays, or the like can be employed.

The light emitting unit 17 may be disposed in the light transmitting unit 13 (for example, in the light transmitting substrate 11), and the light emitting unit 17 and the light transmitting unit 13 are collectively referred to as a light emitting mechanism 18.
In addition, light from the outside of the light-transmitting substrate 11 (below FIG. 2B) is received at the substantially center of the light-transmitting substrate 11 (see FIGS. 2A and 2C). A light receiving sensor 15 that outputs a signal according to the state of light (the amount of light) is attached. The light receiving sensor 15 is disposed between the pins 5.

  Furthermore, the main body 3 of the photohair dyeing device 1 can adjust the light emission state (light quantity) of the switch 19 for turning on and off the photohair dyeing device 1, the speaker 21 for generating electronic sounds and sounds, and the light emitting unit 17. A dimming knob 23 is attached.

  As shown in FIG. 3, the switch 19, the light control knob 23, the light receiving sensor 15, the light emitting unit 17, the speaker 21, and the like are connected to an electronic control device 25 that controls the operation of the photohair dyeing device 1. The electronic control device 25 is connected to a cord 27 (see FIG. 2B) for supplying power from a household power source.

b) Next, the operation of the photohair dyeing apparatus 1 of the present embodiment will be described.
In the case of performing photo hair coloring, a well-known photo hair coloring agent (for example, photosensitive acid hair coloring as shown in JP-A-2008-69131) capable of performing photo hair coloring is previously applied to the hair on the head. Apply to.

And after setting the light quantity level with the light control knob 23 in advance, after pressing the switch 19 of the photohair dyeing apparatus 1, the pin 5 of the photohair dyeing apparatus 1 is put into the hair.
Therefore, as shown in FIG. 4, by operating the switch 19 (step 100), light is emitted from the light emitting portion 17 to the light transmitting substrate 11 (step 110), and the light is shown in FIG. As shown, light is transmitted from the inside of the light transmitting substrate 11 to the inside of the pin 5 so that light is applied to the hair from the lower part of the light transmitting substrate 11, the side or tip of the pin 5 (that is, from the light transmitting portion 13). Irradiation promotes photo-dyeing.

  Moreover, when light is irradiated from the translucent part 13, hair is gradually dyed as time passes, and the color of the hair changes (for example, the hair coloring of gray hair proceeds and is colored black). Therefore, when hair is dyed, the state of light received by the light receiving sensor 15 (particularly reflected light) changes. Specifically, when the hair changes from white hair to black hair, the amount of received light (the reflected light from the hair) decreases.

  Therefore, in this embodiment, when the output of the light receiving sensor 15 after the light is irradiated from the translucent part 13 is monitored and it is determined that the amount of received light has decreased more than a predetermined value, that is, the hair dyeing has sufficiently progressed. If it is determined (step 120), the fact is notified to the user by sound or voice using the speaker 21 (step 130).

The user knows that the hair has been sufficiently dyed by this notification, and in that case, the user can change the position of hair dyeing and dye the hair in other places.
In addition, since the degree of progress of photo hair dyeing can be known by the temporal change of the signal of the light receiving sensor 15, for example, when the hair dyeing does not progress easily, control for increasing the light amount of the light emitting unit 17 may be performed.

c) As described above, in this embodiment, the photo-hair dyeing apparatus 1 can quickly and reliably carry out photo-hair dyeing regardless of the state of sunlight or room lighting.
Further, in this embodiment, when performing photo-dyeing, the user is notified according to the degree of progress of photo-dyeing, so that the user can reliably perform photo-dyeing.

  In particular, when hair is dyed alone, it is difficult to confirm the degree of hair coloring at the top and rear of the head. can do.

In this embodiment, the light emitting unit 17 is disposed at one location adjacent to the light transmitting substrate 11. However, a plurality of light emitting units 17 are disposed adjacent to or within the light transmitting substrate 11. May be.
The transparent portion 13 can be made of a transparent plastic and has a solid structure. However, since the light transmitting portion 13 only needs to be able to irradiate light, the inside may be hollow and the periphery may be a frame made of transparent plastic (the same applies hereinafter). ).

Furthermore, when it is determined that the hair coloring has progressed sufficiently, the light irradiation from the light emitting unit 17 may be turned off or the amount of light may be reduced.
Alternatively, when the photohair dyeing device 1 is separated from the hair, the state of the light received by the light receiving sensor 15 (light quantity, etc.) changes rapidly. It may be determined that the light has been released, and the light irradiation from the light emitting unit 17 may be turned off or the amount of light may be reduced.

Next, the second embodiment will be described, but the description of the same contents as the first embodiment will be simplified.
