[0170] FIG. 17 is a diagram illustrating a status indicator 1700 of the storage case 1 according to various embodiments.

[0171] Referring to FIG. 17, the status indicator 1700 of the storage case 1 may include a light-transmissive area 1113 (see FIGS. 4 and 9) provided (or formed) by the first cover member 111, the light-shielding layer 29 (see FIG. 9), and the light waveguide 28, and a plurality of light sources 30 (see FIG. 5). The status indicator 1700 may be provided (or formed) in the form of a circular band. The storage case 1 may be configured to selectively turn on or off the plurality of light sources 30 so as to visually indicate the status of the storage case 1 and/or the status of the wearable ring device 4 placed in the storage case 1 through the status indicator 1700.

[0172] According to various embodiments, memory (not separately illustrated) included in the storage case 1 may store instructions which, when executed by at least one processor (not separately illustrated) included in the storage case 1, cause the storage case 1 not to emit light from the status indicator 1700 in the folded state. To prevent or suppress the status indicator 1700 from emitting light, the storage case 1 may turn off all of the plurality of light sources 30.

[0173] According to various embodiments, the memory included in the storage case 1 may store instructions which, when executed by at least one processor included in the storage case 1, cause the battery level of the wearable ring device 4 to be displayed via the status indicator 1700 in response to a transition of the storage case 1 from a folded state to an unfolded state while the wearable ring device 4 is placed in the storage case 1.

[0174] According to various embodiments, when the wearable ring device 4 is placed in the storage case 1 and when the storage case 1 is in the unfolded state, a first electrical signal may be generated from the dome switch 252 (see FIG. 2) in response to a short push (e.g., less than about 3 seconds) of the push button 251 (see FIG. 2). According to various embodiments, the memory included in the storage case 1 may store instructions which, when executed by at least one processor included in the storage case 1, cause the status indicator 700 to display the remaining battery level of the battery of the wearable ring device 4 in response to the first electrical signal.

[0175] According to various embodiments, the memory included in the storage case may store instructions which, when executed by at least one processor included in the storage case 1, cause the status indicator 1700 to display the battery level of the battery 22 (see FIG. 2) of the storage case 1 in response to a transition of the storage case 1 from the folded state to the unfolded state when the wearable ring device 4 is not placed in the storage case 1.

[0176] According to various embodiments, when the wearable ring device 4 is not placed in the storage case 1 and when the storage case 1 is in the unfolded state, a first electrical signal may be generated from the dome switch 252 (see FIG. 2) in response to a short push (e.g., less than about 3 seconds) of the push button 251 (see FIG. 2).

[0177] The memory included in the storage case 1 may store instructions which, when executed by at least one processor included in the storage case 1, cause the status indicator 1700 to display the battery level of the battery 22 (see FIG. 2) of the storage case in response to the first electrical signal.

[0178] In various embodiments, the storage case 1 may turn on more of light sources 30 (see FIG. 5) in a clockwise direction so that a larger area of the status indicator 1700 emits light in the clockwise direction as the remaining battery level of the battery (e.g., the battery 22 of the storage case 1 or the battery of the wearable ring device 4) increases. For example, reference numeral 1701 denotes the status indicator 1700 when the remaining battery level of the battery is about 25%, and about one-fourth of a status indicator (e.g., an indicator of the circular band) may emit light. For example, reference numeral 1702 denotes the status indicator 1700 when the remaining battery level of the battery is about 50%, and about one-half of the status indicator may emit light. For example, reference numeral 1703 denotes the status indicator 1700 when the battery is fully charged, and the entire status indicator may emit light.

[0179] According to various embodiments, when the wearable ring device 4 is placed in the storage case 1 and when the storage case 1 is in the unfolded state, a second electrical signal may be generated from the dome switch 252 (see FIG. 2) in response to a long push (e.g., about 3 seconds or more) of the push button 251 (see FIG. 2). According to various embodiments, the memory included in the storage case 1 may store instructions which, when executed by at least one processor included in the storage case 1, cause pairing (also referred to as a pairing mode) to be performed for establishing wireless communication (e.g., short-range communication such as Bluetooth, Bluetooth Low Energy (BLE), Wi-Fi Direct, or IrDA) between the wearable ring device 4 and an external electronic device (e.g., a smartphone) in response to the second electrical signal. The memory included in the storage case 1 may store instructions which, when executed by at least one processor included in the storage case 1, cause the status indicator 1700 to display the pairing in response to the second electrical signal. For example, the storage case 1 may be configured such that the plurality of light sources 30 (see FIG. 5) blink sequentially during pairing corresponding to the second electrical signal.

[0180] According to various embodiments, the operation of a status indicator 1700 may vary depending on the state of the storage case 1 and/or the state of a wearable ring device 4 disposed in the storage case 1.

[0181] According to various example embodiments of the disclosure, a storage case (e.g., the storage case 1) for a wearable ring device (e.g., the wearable ring device 4) includes a first housing (e.g., the first housing 11) and a second housing (e.g., the second housing 12). The first housing is configured to support the wearable ring device. The first housing includes a protrusion (e.g., the first protrusion 1112) configured to allow the wearable ring device to be fitted thereon. The second housing is rotatably connected to the first housing via a hinge (e.g., the hinge 13). The second housing includes a light-transmissive member (e.g., the light-transmissive member 121) having a recess (e.g., the first recess R1) configured to receive the protrusion of the first housing (e.g., the first protrusion 1112) and the wearable ring device in a folded state of the storage case. The second housing includes a ring-shaped support member (e.g., the second support member 123) coupled to the light-transmissive member so as to have an inclined surface (e.g., the inclined surface 123A) configured to surround the wearable ring device in the folded state of the storage case. The inclined surface (e.g., the inclined surface 123A) of the support member (e.g., the second support member 123) is configured to reflect light so that the wearable ring device is visible through the light-transmissive member of the second housing in the folded state of the storage case.
