The control unit causes the notification unit to output notification information based on the result of collation of the blood vessel information and the reference information at the time of current use. For this reason, it becomes easy for a user to recognize that the irradiation position of near-infrared light is not appropriate. When the user recognizes that the irradiation position of the near infrared light is not appropriate, the user can change the irradiation position of the near infrared light. For this reason, it becomes difficult to produce the dispersion | variation in the irradiation position of the near-infrared light for every use of an optical hair growth device.

  In this way, the present optical hair grower notifies the difference between the irradiation position of the near infrared light at the time of use this time and the irradiation position of the reference near infrared light, so that each time the light hair growing apparatus is used.

(1) The alerting | reporting part 80 outputs alerting | reporting information based on the collation conditions not being satisfied. For this reason, the user can recognize that the irradiation position of near-infrared light is not appropriate, and can change the irradiation position. For this reason, it becomes difficult to produce the dispersion | variation in the irradiation position for every use of the optical hair grower 1. FIG. For this reason, the fall of the hair-growth effect becomes difficult to occur.

  (2) The light source unit 60 includes a plurality of light emitting / receiving elements 61. For this reason, the following effects are acquired when compared with a virtual light source part. In addition, the description regarding this effect does not intend to exclude a virtual light source part from one form of the light source part which the optical hair growth device 1 can take.

  A virtual light source part has a plurality of light emitting elements and a plurality of light receiving elements as one form. The total number of light emitting elements and light receiving elements in the virtual light source unit matches the total number of light emitting and receiving elements 61 in the light source unit 60. The light source unit 60 has a larger number of elements that emit light in the light irradiation control than the virtual light source unit. For this reason, a more preferable hair-growth effect is easily obtained.

  As another embodiment, the virtual light source unit has the same number of light emitting elements as the light emitting / receiving elements 61 in the light source unit 60 and a plurality of light receiving elements. The virtual light source unit can set the number of elements to emit light in the light irradiation control to the same number as the light source unit 60. However, since there are a plurality of light receiving elements, the size of the light source unit 60 is increased. Since the light source unit 60 has the light emitting / light receiving element 61 to have a light emitting function and a light receiving function, the number of elements is smaller than that of the virtual light source unit. For this reason, it contributes to size reduction of the optical hair growth device 1.

  (3) The optical hair growth device 1 has an irradiation position confirmation unit 33. For this reason, the operator can start the blood vessel information matching process at an arbitrary timing. For this reason, the opportunity which the light receiver 100 can recognize the shift | offset | difference of the irradiation position of near infrared light increases.

  The light emitting / receiving element 61 of the embodiment has the form of an LED lamp. However, the configuration of the light emitting and receiving element 61 is not limited to the content exemplified in the embodiment. The light emitting / receiving element 61 of the modified example has a form of a laser diode as an example. Note that even when the light source unit 60 includes a light emitting element or a light receiving element, the modification according to the above modification is established.

  The light emitting / receiving element 61 of the embodiment irradiates near-infrared light that shows an intensity peak at a wavelength of 1450 nm. However, the spectrum of near-infrared light irradiated by the light emitting / receiving element 61 is not limited to the content exemplified in the embodiment. The spectrum of near-infrared light emitted by the light emitting / receiving element 61 of the modification has an intensity peak at at least one of the specific absorption wavelengths of water in the near-infrared region. Examples of the specific absorption wavelengths of water include 950 nm, 1150 nm, and 1790 nm.

However, the configuration of the light source unit 60 is not limited to the content exemplified in the embodiment. The light source unit 60 of the modified example irradiates near infrared light having different spectra from some or all of the plurality of light emitting / receiving elements 61 set in the light emitting state.

-The control part 40 of embodiment performs light source operation control (refer FIG. 3 and FIG. 4). However, the content of the light source operation control is not limited to the content exemplified in the embodiment. The control part 40 of a modification has at least one of the following (a)-(c) as an example of another form of light source operation control.
(A) The control unit 40 performs steps S21 and S22 simultaneously.
(B) The control unit 40 omits steps S11, S12, and S15.
(C) The control unit 40 omits steps S13 to S15.

  -The control part 40 of embodiment performs the blood vessel information collation process based on operation of the irradiation position confirmation part 33 in light irradiation control. However, the content of the light irradiation control is not limited to the content exemplified in the embodiment. The control unit 40 according to the modification executes the blood vessel information collation process without depending on the operation of the irradiation position confirmation unit 33 in the light irradiation control. For example, when the control unit 40 determines in step S23 that the end condition is not satisfied, the control unit 40 proceeds to step S11. For this reason, the blood vessel information matching process is performed without depending on the operation of the irradiation position confirmation unit 33. According to this modified example, during the execution of the light irradiation control, variations in the irradiation position of the near infrared light are less likely to occur.

  -Irradiation position confirmation control of embodiment does not have the information correction process shown below. The irradiation position confirmation control of the modification has an information correction process. The control unit 40 performs information correction processing in the irradiation position confirmation control. The information correction process determines whether body hair information is included in the synthesized blood vessel information or the blood vessel information before synthesis. The body hair information indicates information on the body hair of the light receiver 100 existing at the irradiation position of the light source unit 60. In the information correction process, when body hair information is included in the synthesized blood vessel information or the blood vessel information before synthesis, one of the first correction process and the second correction process is executed. In the first correction process, a portion corresponding to body hair information in the blood vessel information is deleted. In the second correction process, the generated synthetic blood vessel information is discarded and the synthetic blood vessel information is generated again. As an example, the controller 40 performs an information correction process between step S15 and step S16. According to this modified example, a situation in which the determination of the matching condition becomes inaccurate is less likely to occur.

  When the storage reference information signal SSM is received from the control unit 40, the storage unit 50 of the embodiment discards the already stored reference information I and stores the reference information I included in the received storage reference information signal SSM To do. However, the structure of the memory | storage part 50 is not restricted to the content illustrated by embodiment.
