The plurality of biosensor light-emitting parts (561) may be disposed further from the center of the first hole (333) than the plurality of light-receiving parts (520). Each of the plurality of biosensor light-emitting parts (561) may be disposed coaxially (e.g., X-axis or Y-axis) with the plurality of light-receiving parts (520). For example, the plurality of biosensor light-emitting parts (561) may be spaced apart from the first light-receiving part (521) along the X-axis in a direction away from the first hole (333). For example, a plurality of biosensor light-emitting parts (561) may be spaced apart from the second light-receiving part (522) along the X-axis in a direction away from the first hole (333). For example, a plurality of biosensor light-emitting parts (561) may be spaced apart from the third light-receiving part (523) along the X-axis in a direction away from the first hole (333). For example, a plurality of biosensor light-emitting parts (521) may be spaced apart from the fourth light-receiving part (524) along the X-axis in a direction away from the first hole (333).

[0115] According to one embodiment, a plurality of biosensor light-emitting units (561) may be spaced apart from each other.

[0116] According to one embodiment, the biosensor module (502) may include a plurality of biosensor light receiving units (562). The plurality of biosensor light receiving units (562) may be disposed on a third surface (e.g., 3321 in FIG. 5c). The plurality of biosensor light receiving units (562) may be spaced apart from each other. The plurality of biosensor light receiving units (562) may be spaced apart from the plurality of biosensor light emitting units (561). For example, when the plurality of biosensor light emitting units (561) are spaced apart at a certain angle from the light measuring unit (550), the plurality of biosensor light receiving units (562) may be spaced apart at a certain angle from each of the plurality of biosensor light emitting units (561).

For example, when a target amount of light is output from the plurality of light-emitting units (e.g., 510 in FIG. 9b or 9c), the output light can be irradiated onto the skin. For example, if light is output from a light-emitting unit (e.g., 510 in FIG. 9b or 9c) that is less than the target amount of light, the integrated circuit (e.g., 581 in FIG. 9b or 9c) can control the light-emitting units (e.g., 510 in FIG. 9b) again to output the target amount of light based on the amount of light measured through the light measuring unit (e.g., 550 in FIG. 9b or 9c). The light irradiated onto the skin can be reflected and received by light-receiving units (e.g., 520 in FIG. 9b or 620 in FIG. 9c). The received light can be transmitted to the processor (120) through the integrated circuit (e.g., the integrated circuit (581) in FIG. 9b or 9c).
