FIG. 5 is a view showing a stylus of a display device according to an embodiment of the present invention, and FIG. 6 is a view illustrating a fixing part of a display device according to an embodiment of the present invention.

The stylus pen 420 and the fixing portion 440 can be mounted inside the barrel 410 of the roller unit 400. [ The stylus pen 420 and the fixing portion 440 can be designed to be variable in length.

Referring to FIG. 5, the stylus pen 420 is housed inside the lens barrel 410. Specifically, the stylus pen 420 may be connected to the first protrusion 430 and inserted into the barrel 410. The radius of the stylus pen 420 may be smaller than the radius of the barrel 410. Therefore, the stylus pen 420 can be housed inside the lens barrel 410 by inserting the stylus pen 420 on one side of the lens barrel 410 from the second direction D2.

In addition, the stylus pen 420 can be separated from the barrel 410. At this time, the first protrusion 430 can be separated from the barrel 410 together with the stylus pen 420. That is, the first protrusions 430 may be disposed on one side of the stylus pen 420 in the second direction D2 in the second direction D2. The pen point 420c of the stylus pen 420 may be disposed on the other side of the stylus pen 420 in the second direction D2.

The stylus pen 420 includes a first portion 420a and a second portion 420b. One side of the first portion 420a in the second direction D2 is connected to the first protrusion 430 and the other side is connected to the second portion 420b. The second portion 420b may be drawn into or out of the first portion 420a. One side of the second portion 420b in the second direction D1 is connected to the other side of the first portion 420a. A pen tip 420c of the stylus pen 420 is disposed on the other side of the second portion 420b.

The partition 410a may be disposed inside the barrel 410. The partition 410a isolates the stylus pen 420 mounted in the barrel 410 from the fixing portion 440. [

The stylus pen 420 may be inserted into the barrel 410 and the pen tip 420c connected to the other side of the second portion 420b may contact the partition wall portion 410a. In this case, the second part 420b can be drawn into the first part 420a by an external force. Therefore, the length of the stylus pen 420 can be reduced and inserted into the barrel 410.

When the stylus pen 420 is withdrawn from the barrel 410, the second portion 420b can be drawn by the user from the first portion 420a. That is, the length of the stylus pen can be extended.

Referring to FIG. 6, the fixing unit 440 is accommodated in the barrel 410. The radius of curvature of the fixing portion 440 may be smaller than the radius of curvature of the barrel 410. [ Therefore, the fixing portion 440 can be received in the barrel 410 by inserting the fixing portion 440 on the other side of the barrel 410.

Also, the fixing portion 440 housed in the lens barrel 410 can extend in the second direction D2. At this time, the second protrusion 450 may be disposed on one side of the fixing part 440 in the second direction D2 and extend together with the fixing part 440. [

The rotary member 460 may be disposed on the other side of the fixing portion 440 in the second direction D2. That is, the other side of the fixing portion 440 may be connected to the other side of the barrel 410 in the second direction D2 through the rotary member 460. [

Specifically, the fixing portion 440 may include a first extending portion 440a, a second extending portion 440b, and a third extending portion 440c. The radius of curvature of the third extension 440c is less than the radius of curvature of the barrel 410 and the radius of curvature of the second extension 440b is less than the radius of curvature of the third extension 420c, The radius of curvature of the first portion 440a is smaller than the radius of curvature of the second portion 420b.

One side of the first extension 440a in the second direction D2 is connected to the second protrusion 450 and the other side is connected to the second extension 440b. The first extension 440a may be drawn into the second extension 440b or may be drawn out.

One side of the second extending portion 440b in the second direction D2 is connected to the first extending portion 440a and the other side is connected to the third extending portion 440c. The second extending portion 440b can be inserted into the third extending portion 440c or drawn out to the outside.

One side of the third extension 440c in the second direction D2 is connected to the second extension 440b and the other side is connected to the rotary member 460. [ The third extension 440c can be drawn into the barrel 410 or drawn out.

The fixing member 440 is inserted into the barrel 410 and the rotary member 460 connected to the other side of the third extension part 440c can be brought into contact with the partition wall part 410a. In this case, the first extended portion 440c can be drawn into the second extended portion 440b by the external force, and the second extended portion 440b can be drawn into the third extended portion 440c have. Therefore, the length of the fixing portion 440 can be reduced and inserted into the barrel 410.

The rotating member 460 can be designed to be rotatable. The rotation member 460 may rotate the fixing unit 440 extending in the second direction D2 in the first direction D1 toward the storage unit 300. [ At this time, the length of the fixing portion 440 may be extended corresponding to the length of the display portion 200 in the first direction D1.

The second protruding portion 450 connected to one side of the extended fixing portion 440 may be in contact with one side of the receiving portion 300 in the first direction D1. The fixing portion 440 can be fixed by the contact of the second protrusion 450 with the receiving portion 300. [

That is, when the display unit 200 is unfolded in the first direction D1, the display unit 200 can be rewound in the direction toward the storage unit 300, which is the opposite direction of the first direction D1. The fixing portion 440 can prevent the display portion 200 from being rewound in the direction toward the receiving portion 300. [

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible. In addition, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, and all technical ideas which fall within the scope of the following claims and equivalents thereof should be interpreted as being included in the scope of the present invention .
