A power supply unit is detachably attached to an accommodating chamber in a distal end portion of a temple. The power supply unit includes, from a front end toward a rear end, an electrical connection terminal; a first housing unit that holds a first battery, and that has a side surface having an arc shape in a plan view; a narrow portion that is connected to the arc-shaped side surface, and that has a side surface narrower than the side surface; and a second housing unit that has a side surface connected to the narrow side surface, and that hold a second battery. The accommodating chamber has a protruding portion that is elastically deformed so as to be fitted to the narrow portion of the power supply unit. ## Claims ### Claim 1 An eyewear comprising: an input unit that receives an input from a user; a control module that is accommodated in a temple so as to perform electric control in response to the input from the input unit; an accommodating unit that is located in a rear end portion of the temple, and that is open on an inner surface and a rear surface continuous with the inner surface of the temple so as to detachably accommodate a power supply unit; a power supply unit that has a first electrical connection terminal and a housing unit; and a second electrical connection terminal that is accommodated in the temple, and that is electrically connected to the first electrical connection terminal of the power supply unit accommodated in the accommodating unit so as to supply power from the power supply unit to the control module, wherein the accommodating unit has a protruding portion which is elastically deformed so as to be fitted to the power supply unit, wherein the housing unit is provided with a narrow portion to which the protruding portion is fitted when the power supply unit is mounted on the accommodating unit, wherein, in a state where the power supply unit is mounted on the accommodating unit, a side surface of the housing unit is covered by the protruding portion, a rear surface and an upper surface adjacent to the rear surface of the housing unit of the power supply unit in a direction in which the power supply unit is inserted into the accommodating unit are respectively exposed from the rear surface and the inner surface of the temple so as to form a portion of a surface of the temple, and the power supply unit is not exposed on an outer surface of the temple which is located on a side opposite to the inner surface of the temple, wherein the housing unit has a first housing unit that holds a first battery, and that has a side surface having an arc shape in a plan view, and a second housing unit that holds a second battery, and wherein the narrow portion has a side surface that is connected to the side surface of the first housing unit, and that is narrower than the side surface. ### Claim 2 (depends on 1) The eyewear according to claim 1, wherein a lower surface of the power supply unit is formed of a flat member which has a smooth flat surface. ### Claim 3 (depends on 2) The eyewear according to claim 2, further comprising a recessed portion or a projection portion extending in a width direction and disposed on the upper surface of the housing unit. ### Claim 4 (depends on 2) The eyewear according to claim 2, wherein, in a state where the power supply unit is mounted on the accommodating unit, the flat member is exposed from the rear surface of the temple, and the exposed flat member is colored so as to have a color which is different from at least a color of the temple. ### Claim 5 (depends on 1) The eyewear according to claim 1, wherein a thickness of the power supply unit increases from the first housing unit toward the second housing unit. ### Claim 6 (depends on 1) The eyewear according to claim 1, wherein a width of the side surface of the second housing unit is wider than a width of the side surface of the narrow portion. ### Claim 7 (depends on 1) The eyewear according to claim 1, wherein the first battery is a button battery. ### Claim 8 (depends on 1) The eyewear according to claim 1, wherein the first and second electrical connection terminals are disposed at a predetermined interval, and wherein a projection portion having a predetermined height is disposed between the first and second electrical connection terminals. ### Claim 9 (depends on 8) The eyewear according to claim 8, wherein the projection portion extends from a front end of the power supply unit to a front portion of the side surface of the housing unit, and configured to be brought into contact with or fixed to the front portion. ### Claim 10 Electronic eyeglasses comprising: a control module that is accommodated in a temple; an accommodating unit that is located in a rear end portion of the temple, and that is open on an inner surface and a rear surface continuous with the inner surface of the temple so as to detachably accommodate a power supply unit; a power supply unit that has a first electrical connection terminal; and a second electrical connection terminal that is accommodated in the temple, and that is electrically connected to the first electrical connection terminal of the power supply unit accommodated in the accommodating unit so as to supply power from the power supply unit to the control module, wherein, from a front end toward a rear end, the power supply unit includes: the first electrical connection terminal; a first housing unit that holds a first battery, the first housing unit comprising a planarly arc-shaped side surface; a narrow portion that has a side surface connected to the planarly arc-shaped side surface, wherein the side surface of the narrow portion is narrower than the planarly arc-shaped side surface; and a second housing unit that holds a second battery, wherein the second housing unit comprises a side surface connected to the side surface of the narrow portion, and wherein the accommodating unit has a protruding portion that is configured to be elastically deformed so as to be fitted to the narrow portion of the power supply unit, and wherein, in a state where the power supply unit is mounted on the accommodating unit, the planarly arc-shaped side surface of the first housing unit, the side surface of the narrow portion, and the side surface of the second housing unit are covered by the protruding portion, a rear surface and an upper surface adjacent to the rear surface of the housing unit of the power supply unit in a direction in which the power supply unit is inserted into the accommodating unit are respectively exposed from the rear surface and the inner surface of the temple so as to form a portion of a surface of the temple, and the power supply unit is not exposed on an outer surface of the temple which is located on a side opposite to the inner surface of the temple. ### Claim 11 (depends on 10) The electronic eyeglasses according to claim 10, wherein a thickness of the power supply unit increases from the first housing unit toward the second housing unit. ### Claim 12 (depends on 11) The electronic eyeglasses according to claim 11, wherein an upper surface of the first housing unit has a recessed portion or a projection portion extending in a width direction. ### Claim 13 (depends on 10) The electronic eyeglasses according to claim 10, wherein a width of the side surface of the second housing unit is wider than a width of the side surface of the narrow portion. ### Claim 14 (depends on 10) The electronic eyeglasses according to claim 10, wherein the first battery is a button battery.
