Referring to FIG. 10, in the rear camera photographing mode of the electronic device, a portion (or a portion of the electronic device) of the side surface of the exterior cover 10 may be in contact with the second surface 215 of the first support portion 210 thereon.
In the vertical photographing mode of the embodiment shown in FIG. 8, a user may simply rotate the cover portion 100 along the third rotational axis A3 by a predetermined angle (e.g., 90 degrees), and thus the same photographing mode as the embodiment shown in FIG. 10 may be implemented.
Referring to FIGS. 11A, 11B, and 11C, various examples of the horizontal photographing mode are shown. Various angles α1′, α2′, and α3′ formed by the first support portion 210 and the second support portion 220 may be an acute angle. Angles β1′, β2′, and β3′ formed by the first support portion 210 and the cover portion 100 may be changed depending on angles α1′, α2′, and α3′ formed by the first support portion 210 and the second support portion 220.
FIG. 11A illustrates a general rear camera horizontal photographing mode in which each of angle α1′ formed by the first support portion 210 and the second support portion 220 and angle β1′ formed by the first support portion 210 and the cover portion 100 is an acute angle.
FIG. 11B illustrates a rear camera vertical photographing mode that is approximately perpendicular to the ground, wherein angle α2′ formed by the first support portion 210 and the second support portion 220 is an acute angle, and angle β2′ formed by the support portion 210 and the cover portion 100 is substantially perpendicular. In this case, the user may select the front camera horizontal photographing mode instead of the rear camera horizontal photographing mode.
FIG. 11C illustrates a front camera horizontal photographing mode in which angle α3′ formed by the first support portion 210 and the second support portion 220 is an acute angle, but angle β3′ formed by the support portion 210 and the cover portion 100 is an obtuse angle.
Referring to FIGS. 11A, 11B, and 11C, a user may simply adjust angle α′ formed by the first support portion 210 and the second support portion 220 to change angle β′ formed by the first support portion 210 and the cover portion 100, whereby the mounting mode of the electronic device can be implemented more variously and freely. The user may finely adjust an inclination angle of the electronic device with respect to the ground, and if it is determined that a predetermined angle is suitable for taking a picture, the user may perform a photographing operation while stably maintaining the corresponding angle.
Based on a comparison between the embodiments of FIGS. 9A, 9B, and 9C and FIGS. 11A, 11B, and 11C, in the horizontal photographing mode of FIGS. 11A, 11B, and 11C, the side surface of the cover portion 100 may contact the second surface 215 and a portion contacting the ground may not be provided.
According to various embodiments, in the rear camera photographing mode and the front camera photographing mode, a portion of the first support portion 210 in contact with at least a portion of the electronic device or the exterior cover 10 (e.g., at least a portion of the second surface 215) may include an anti-slip portion (e.g., a portion containing a frictional material). For example, the at least a portion of the second surface 215 may be made of a material having high frictional force such as rubber and urethane. As a result, when the electronic device or the external cover is mounted on the first support portion 210, it is possible to prevent the electronic device or the external cover from sliding on the second surface 215 unless the user forcibly applies an external force.
Referring to FIGS. 5 and 8 and FIGS. 11A, 11B, and 11C together, according to various embodiments, the first support portion 210 may rotate with respect to the second support portion 220 by a first maximum allowable angle along the direction of the first rotational axis A1. According to various embodiments, the second support portion 220 may rotate with respect to the third support portion 230 by a second maximum allowable angle greater than the first maximum allowable angle along the direction of the second rotational axis A2. Here, the first maximum allowable angle may be a maximum allowable angle of angle α formed by the first support portion 210 and the second support portion 220, and may correspond to, for example, 60 degrees or 90 degrees. The second maximum allowable angle may be a maximum allowable angle of an angle formed by the second support portion 220 with respect to the third support portion 220, and may correspond to, for example, 180 degrees. On the other hand, since the third support portion 230 rotates in place in a state of being fixed to the rear surface 112 of the cover portion 100 and does not have a structure preventing rotation around the third support portion 230, thereby allowing the first support portion 210 and the second support portion 220 to rotate (rotate 360 degrees) along the direction of the third rotation axis A3 without angle limitation.
