[0133] When the inner wing (710) pivots and moves about the pivot axis (WA), the indicator (717) can be detected by the first sensor (S1). When the inner wing (710) pivots and moves in reverse about the pivot axis (WA), the indicator (717) can be detected by the second sensor (S2). Depending on the pivot movement of the inner wing (710), the indicator (717) can move closer to the first sensor (S1) or closer to the second sensor (S2).

The first inner wing (710a) can pivot about a pivot axis (WA). The first outer wing (730a) is coupled to the first inner wing (710a) and can pivot together with the first inner wing (710a).

[0136] When the fifth gear (642) rotates, the second wing end gear (720b) ​​of the second inner wing (710b) can rotate together with the fifth gear (642). The second inner wing (710b) can pivot around the pivot axis (WA). The second outer wing (730b) is coupled to the second inner wing (710b) and can pivot together with the second inner wing (710b).

[0137] Referring to FIG. 13, the rotational force provided by the motor (610) is transmitted through the gear sets (620, 630, 640) so that the inner wing (710) and the outer wing (730) can pivot about the pivot axis (WA). Accordingly, the wings (710, 730) can be driven with low power consumption, and miniaturization of the driving mechanism can be achieved. In addition, noise and / or vibration generated when the wings (710, 730) are driven can be reduced. In addition, the operating range of the wings (710, 730) can be varied by replacing the outer wing (730).
