The slide rail 150 may be made of metal or injection molded material. The inside of the slide rail 150 may be exposed to the outside through the slide slit 141. Accordingly, the roller assembly 230 may pass through the slide slit 141 and be connected to the slide rail 150.

A stopper 153 may be provided at the front end of the slide rail 150 to prevent the roller assembly 230 from leaving the front end of the slide rail 150. One surface of the stopper 153 facing the slide rail 150 may be provided with a buffer member 153a (see FIG. 17) that can alleviate impact when the roller assembly 230 collides.

Referring to FIG. 10 , the slide rail 150 may include a base part 151 extending front and rear and side parts 152 bent upward on both sides of the base part 151 in the width direction. The side part 152 may be bent multiple times. For example, the longitudinal cross-sectional shape of the side part 152 may have an overall 'ㄷ' shape. The first roller part (233a, see FIG. 16) of the roller assembly 230 may be disposed inside the side part 152, and the second roller part of the roller assembly 230 may be placed on the upper part of the side part 152 ( 233b, see FIG. 16) may be arranged.

At least one positioning hole 152a may be formed in the side part 152. As an example, the positioning hole 152a may be provided at the front and rear ends of the side part 152. The positioning hole 152a may be provided to determine the position of the roller assembly 230. In other words, while the roller assembly 230 slides and the roller assembly positioning member 233c is inserted into the positioning hole 152a, the position of the roller assembly 230 can be determined. Afterwards, when a predetermined external force is applied to the roller assembly 230, the roller assembly positioning member 233c is separated from the positioning hole 152a and can be slid.

Referring to FIG. 11, a position sensor 154 that senses the position of the roller assembly 230 may be disposed on at least one of the front end or the rear end of the slide rail 150. For example, the position sensor 154 may be disposed at the rear end of the slide rail 150. The position sensor 154 may be directly coupled to the rear end of the slide rail 150 or may be disposed at the rear end of the slide rail 150 while being coupled to the mount lower housing 130 or the mount upper housing 140.

For example, the position sensor 154 may include at least one of a micro switch, a reed switch, a proximity sensor, an optical sensor, and a hall sensor. When the position sensor 154 is provided as a micro switch, it is possible to determine whether the roller assembly 230 is placed at the rear end or front end of the slide rail by detecting whether the roller assembly 230 is in contact.

When the position sensor 154 is provided as a reed switch, the reed switch may be provided in the upper mount housing 140 corresponding to at least one of the front end or the rear end of the slide rail 150. As an example, the reed switch may be provided on at least one of one side of the mount upper housing 140 corresponding to the front end of the slide rail 150 or one side of the mount upper housing 140 corresponding to the rear end of the slide rail 150. there is. However, it is also possible to provide the reed switch directly on at least one of the front or rear end of the slide rail 150, or in the lower mount housing 130 corresponding to at least one of the front or rear end of the slide rail 150. Meanwhile, the roller assembly 230 may be equipped with a magnet that can turn the reed switch on/off. As an example, the magnet may be fixed to the roller assembly 230 by a separate magnet bracket. When the roller assembly 230 slides along the slide rail 150 and the magnet provided in the roller assembly 230 is disposed to face the reed switch, the reed switch may be turned on. Additionally, when the magnet moves away from the reed switch, the reed switch may be turned off. The control unit can determine the position of the roller assembly 230 through whether the reed switch is on/off.

The control unit may control the wavelength and amount of light emitted from the optical module 300 based on the position information of the roller assembly 230 received from the position sensor 154. For example, when the roller assembly 230 is located at the rear end of the slide rail 150 (when in contact with the position sensor 154), the controller sets the wavelength and light quantity suitable for the user's scalp care in the scalp care mode. The optical module 300 can be controlled to emit light. Conversely, when the roller assembly 230 is located at the front end of the slide rail (when it is not in contact with the position sensor 154), the control unit irradiates light of a wavelength and amount suitable for the user's face care in the face care mode. The optical module 300 can be controlled. At this time, the amount of light (or intensity of light) emitted in the scalp care mode may be greater than the amount of light (intensity of light) emitted in the face care mode (for the purpose of protecting the user's vision).

The second roller part 233b may be disposed on the upper part of the slide rail 150. For example, the second roller part 233b may be disposed on the upper part of the side part 152 of the slide rail 150. By arranging the first roller part 233a and the second roller part 233b inside and above the side part 152 of the slide rail 150, respectively, the roller assembly 230 slides along the slide rail 150. In this case, the roller assembly 230 can be stably supported on the slide rail 150.

The roller assembly 230 may be inserted into the slide rail 150 from the front of the mount upper housing 140 so that the side panel 232 is disposed in the gap. At this time, the roller assembly 230 may be inserted so that the first roller part 233a is disposed inside the side part 152 and the second roller part 233b is disposed on the upper part of the side part 152.

When the roller assembly 230 is inserted into the slide rail 150, a stopper 153 may be coupled to the front end of the slide rail 1520.

The light emitting module 320 can radiate light of various wavelengths corresponding to the position of the slide unit 200. For example, when the slide unit 200 is located at the rear of the mount unit 100 and radiates light to the user's scalp (scalp care mode), the light emitting module 320 is effective in scalp care or hair loss prevention. Light in a certain wavelength range can be irradiated to the user's scalp. In addition, when the slide unit 200 slides forward and is located in front of the mount unit 100 (face care mode), the light emitting module 320 emits light in a wavelength band effective for whitening or wrinkle improvement to the user. The face can be irradiated. For example, the light emitting module 320 can selectively irradiate light in the 420-480 nm, 630-690 nm, or 850-940 nm wavelength band to the user's scalp or face.

The light emitting module cover 330 may be coupled to the diffusion plate 310.
