The springs included in the door cushions 127 and 128 absorb the impact applied to the inner case 120 and prevent the door outer 130 Can support.

4 is a view showing a detailed configuration of a first fixing part of a thermal printer according to an embodiment of the present invention.

(이하, A라 한다)와 같은 형태 및

(이하, B라 한다)와 같은 형태를 포함할 수 있다. 예를 들어, 이너 케이스(120)에는 A 형태의 제1 고정부(123)가 형성되고 도어 아우터(130)에는 B 형태의 제1 고정부(133)가 형성될 수 있고, 상기 A 형태 및 B 형태의 제1 고정부는 이너 케이스(120)와 도어 아우터(130)가 수직 방향이 되는 경우, 고정될 수 있다. 따라서, 사용자는 도어 아우터(130)가 오픈되어 고정되므로, 프린터 용지를 용이하게 교체할 수 있다.4, when the door outer 130 is maximally opened so as to be perpendicular to the inner case 120, the door outer 130 may be fixed by the first fixing portions 123, 124, 133, have. Specifically, the first fixing portions 123, 124, 133, and 134

(Hereinafter referred to as " A ") and

(Hereinafter referred to as " B "). For example, an A-shaped first fixing portion 123 may be formed on the inner case 120 and a B-shaped first fixing portion 133 may be formed on the door outer 130, The first fixing part may be fixed when the inner case 120 and the door outer 130 are vertically oriented. Therefore, the user can easily replace the printer paper because the door outer 130 is opened and fixed.

5A to 5C are views for explaining the process of coupling the door outer of the thermal printer to the inner case according to an embodiment of the present invention.

5A, when the door outer 130 is opened and fixed, the door outer 130 is coupled to the first hinge portions 121 and 122 and the second hinge portions 131 and 132, And can be rotated from the upper side to the lower side. 5B, the angle formed between the door outer 130 and the inner case 120 is fixed by the first fixing portions 123, 124, 133, and 134 to a predetermined size, The outer rotor 130 is rotated from the upper side to the lower side by gravity.

The door outer 130 may then contact at least one door cushion 127, 128 formed in the inner case 120. In this case, the door cushions 127 and 128 can absorb a shock applied to the door outer 130 and the inner case 120, including a spring.

5C, the door fixing member 130 and the second fixing portions 125, 126, 135, and 136 formed on the inner case 120 may be coupled to each other.

6A and 6B are views for explaining a detailed configuration of the first hinge portion and the second hinge portion according to the embodiment of the present invention.

6A, the first hinge portions 121 and 122 are formed of a plurality of hinge holes 121 and 122, and are engaged with the second hinge portions 131 and 132 formed on the door outer 130, So that the outer rotor 130 can be rotated from the upper side to the lower side about the rotation axis fixed to the inner case 120. In this case, the second hinge portions 131 and 132 may include a plurality of hinge protrusions 131 and 132, and each of the hinge protrusions 131 and 132 may include a protrusion that is inclined at a predetermined angle. For example, as shown in FIG. 6B, the hinge protrusion 132 may be a protrusion including a sloped surface on one side and a sloped surface inclined by 15 degrees on the opposite side. One side of the hinge protrusion 132 according to one embodiment of the present invention is formed as a protrusion including an inclined surface inclined at 15 degrees so that when the door outer 130 is separated from the inner case 120, ) Is rotated 15 degrees backward and can be easily separated. However, the present invention is not limited thereto, and the hinge protrusions 131 and 132 may be formed of protrusions inclined at an angle of 0 to 90 degrees in addition to 15 degrees. The user can easily separate and fasten the door outer 130 and the inner case 120 since the door outer 130 can be rotated and rotated backward by an angle of the hinge protrusions 131 and 132 .

The thermal printer and force system according to various embodiments of the present invention can easily separate and connect the door outer of the thermal printer so that the user can easily replace the printer paper, .

In addition, when the door outer of the thermal printer is separated or coupled, the impact applied to the door outer and inner case can be minimized, thereby preventing the door outer and the inner case from being damaged.

Although the preferred embodiments of the present invention have been illustrated and described using specific terms, such terms are used only for the purpose of clarifying the present invention, and the embodiments of the present invention and the described terminology should be construed to cover the technical scope and scope of the following claims It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention.

For example, in the above description, a display device such as a monitor is described as an object to be fixed to the mounting mechanism of the present invention. However, if a device other than a monitor needs a separate mounting mechanism for use such as a speaker and a wall- It will be apparent to those skilled in the art that the present invention is not limited thereto and can be extended.

Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should be within the scope of the present invention.
