The anti-rotation stopper 296 protrudes downward (-Z axis direction).

The pair of anti-rotation stoppers 295 and 296 may be disposed such that the first hinge 270 and the second hinge 280 of the photographing unit 200 have a rotation angle of 0 °, that is, the first casing 251. ) And the second casing 256 are disposed to have a rotation angle of 0 ° (see FIGS. 17 and 20), so that they can be spaced apart from each other by 90 ° in the counterclockwise direction.

17 to 21 are views for explaining various rotation operations of the photographing unit of FIG.

Referring to FIG. 17, when the display apparatus 1 is disposed toward the front (+ Z axis direction) of the photographing unit 200 protruding from the display main body 10, the first casing 251 and the second casing 256 may be used. ) Are arranged to have rotation angles of 0 ° to each other.

In this case, the first locking protrusion 285 (see FIGS. 15 and 16) of the second hinge 280 (see FIGS. 15 and 16) may include the first locking groove (see FIG. 15 and FIG. 16) of the first hinge (see FIGS. 273, see FIGS. 15 and 16, and the second locking protrusion 286, see FIGS. 15 and 16 of the second hinge 280, has a second locking groove 274 of the first hinge 270. 15 and FIG. 16).

The user can appropriately rotate the photographing unit 200 in a desired direction in the horizontal direction (Y-axis direction) through a user operation as needed. Hereinafter, various rotation operations of the photographing unit 200 according to the user operation will be described.

First, the user may rotate the second casing 256 of the photographing unit 200 in a clockwise direction. According to a user's rotation operation, the second casing 256 of the photographing unit 200 may be rotated in a horizontal direction (Y-axis direction) with respect to the first casing 251.

According to the user's clockwise rotation operation, as shown in FIG. 18, the second casing 256 of the photographing unit 200 stops while being rotated 90 ° along the clockwise direction. At this time, the first locking protrusion 285 is locked to the third locking groove 275, and the second locking protrusion 286 is locked to the fourth locking groove 276. Accordingly, upon completion of 90 ° rotation of the second casing 256 in the clockwise direction, the photographing unit 200 provides a user with a hinge click. Accordingly, the photographing unit 200 faces the right direction (-Y axis direction) when viewed from the rear of the display apparatus 1 (-X axis direction).

When the user rotates clockwise again, as shown in FIG. 19, the second casing 256 of the photographing unit 200 stops while being rotated 90 ° again along the clockwise direction. That is, the second casing 256 of the photographing unit 200 is rotated 180 degrees clockwise from the initial 0 ° position. At this time, the first locking protrusion 285 is locked to the second locking groove 274, and the second locking protrusion 286 is locked to the first locking groove 273. In this case, too, the photographing unit 200 may provide a user with a hinge click feeling. Accordingly, the photographing unit 200 faces the rear of the display apparatus 1 (-X axis direction).

In addition, at this time, the pair of anti-rotation stoppers 295 and 296 are disposed to mesh with each other. Accordingly, the user does not rotate the clockwise direction. For this reason, no rotation greater than 180 ° clockwise occurs at the initial 0 ° position of the second casing 256. Therefore, a problem such as disconnection of the cable C due to the rotation of the second casing 256 can be prevented.

Referring to FIG. 20, as shown in FIG. 17, a state in which the first casing 251 and the second casing 256 are disposed to have a rotation angle of 0 ° with each other is disclosed. On the other hand, the user can also rotate the second casing 256 in the counterclockwise direction opposite to the previous FIGS. 17 to 19.

As shown in FIG. 21, when the user rotates in the counterclockwise direction, the second casing 256 of the photographing unit 200 stops while being rotated 90 ° in the counterclockwise direction. At this time, the first locking protrusion 285 is locked to the fourth locking groove 276, and the second locking protrusion 286 is locked to the third locking groove 275. In this case, too, the photographing unit 200 provides a user with a hinge click feeling. Accordingly, the photographing unit 200 faces toward the left side (+ Y-axis direction) when viewed from the rear of the display apparatus 1 (-X-axis direction).

At this time, the pair of anti-rotation stoppers 295 and 296 are disposed to mesh with each other. Accordingly, the rotation operation in the counterclockwise direction of the user is no longer made. That is, in the present embodiment, the second casing 256 of the photographing unit 200 does not rotate more than 90 ° in the counterclockwise direction.

As described above, the photographing unit 200 according to the present exemplary embodiment may be disposed in all directions in front, rear, left and right directions in the Y-axis direction while preventing disconnection of the cable C (see FIG. 14).

As such, the display apparatus 1 according to the present exemplary embodiment may expose the photographing unit 200 to the outside of the display main body 10 only when photographing, and may appropriately rotate the exposed photographing unit 200 at a desired angle. .

Therefore, the display apparatus 1 according to the present exemplary embodiment may provide the display apparatus 1 capable of securing the photographing angles of the various photographing units 200 while improving the aesthetics of the display apparatus 1.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
