Referring to FIG. 2, the cover 110 is rotated and opened. The cover 110 is provided with a conveying guide 130 for conveying the recording sheet on an inner bottom surface thereof.

The transport guide 130 is provided on the lower surface of the cover 110 but may not be connected to the cover 110 but may be separately formed inside the case 100.

The cover 110 is configured to be opened and closed at one side of the discharge port 140 through which the recording paper is discharged, and the discharge port 140 communicates with the accommodation space 120. In the receiving space 120, the recording paper is received in a wound state and discharged to the outside through the discharge port 140.

As described above, the cover 110 is configured to selectively open and close the accommodation space 120, and when the cover 110 is closed, the case 100 and the outlet 140 are formed. In this embodiment, the cover 110 is configured to be vertically tiltable from one side of the case 100 to cover the accommodation space 120.

In addition, the case 100 according to the present invention may further include a separate conveying roller 200 for conveying the recording sheet accommodated in the accommodating space 120 to the outside.

The conveying roller 200 has a predetermined width and is rotatably coupled to the inside of the case 100 to convey the recording sheet. The conveying roller 200 is coupled to one side of the conveying guide 130 and the recording sheet moves along the conveying guide 130 and is discharged to the outside by the rotation of the conveying roller 200.

Meanwhile, the thermal head 300 is provided on the conveyance path of the recording sheet discharged from the case 100 through the discharge port 140, and one side of the thermal head 300 contacts the recording sheet to generate heat.

Specifically, one side of the path through which the recording sheet is conveyed comes into contact with the recording sheet, generates heat, and is printed on the recording sheet to which heat is transferred. Here, the recording paper is a thermoelectric paper.

The thermal head 300 is coupled to a lower surface of the cover 110 and is located inside the accommodation space 120 according to the open / closed state of the cover 110.

The thermal head 300 according to the present invention has a shape corresponding to the shape of the conveyance guide 130 and is spaced apart from the conveyance guide 130 by a predetermined distance in a state in which the cover 110 is closed .

When the thermal head 300 is positioned inside the accommodating space 120 with the cover 110 closed, the recording sheet is transported between the thermal head 300 and the transport guide 130, The thermal head 300 is configured to contact the recording paper.

As described above, the thermal head 300 according to the present invention can print on the recording paper when the recording paper accommodated in the accommodating space 120 is transferred to the outside and discharged.

The thermal head 300 according to the present invention is coupled to the lower surface of the cover 110 to selectively adjust the position of the thermal head 300 according to the opening and closing states of the cover 110. Alternatively, The thermal head 300 may be coupled directly to the case 100 instead of the thermal head 110.

The tear bar 400 according to the present invention is configured to be slidable in the case 100 and a cutter 410 is provided at one side of the tear bar 400 so that the cutter 410 can be moved outside the case 100 .

Specifically, the tear bar 400 is slidably provided in the case 100 in the direction of the discharge opening 140, and the cutter 410 is formed on one side.

In addition, the tear bar 400 selectively exposes the cutter 410 to the outside of the case 100 according to the sliding state, so that the recording sheet is cut by pressing the user.

At this time, the cutter 410 formed on one side of the tier bar 400 is formed in a saw blade shape so that the recording paper can be cut by a general thermal printer 10 by pressing.

In the present embodiment, the tier bar 400 is configured to be slidable in the lateral direction inside the case 100, and the sliding is controlled according to the rotation state of the rotation driving unit 500 described later. Here, the tear bar 400 slides so that the cutter 410 may be exposed toward the discharge port 140.

The cutter 410 may be configured as a separate member from the tear bar 400 and may be replaced by a user. Alternatively, the cutter 410 may be configured to be replaceable by a user, May be integrally formed.

The rotation driving part 500 according to the present invention is disposed adjacent to the tear bar 400 in the case 100 and is rotatable to adjust the sliding state of the tear bar 400 according to the rotation state .

Specifically, when the cover 110 is closed, the rotation driving unit 500 rotates so that the tear bar 400 slides in the direction of the discharge port 140 so that the cutter 410 is exposed to the outside.

In the present embodiment, the rotation driving part 500 is configured to be long and rotatable in the vertical direction about the central part in the longitudinal direction. The rotation driving unit 500 is configured to slide the tier bar 400 by contacting one side of the tier bar 400 according to the rotation state.

As shown in the figure, when the cover 110 is opened, the rotation driving unit 500 rotates counterclockwise and the tier bar 400 slides to the left. When the cover 110 is closed, (400) rotates in a clockwise direction and one side pushes the tier bar (400) to the right.

At this time, as shown in the figure, the cover 110 is formed with a protrusion 112 protruding in the direction of the accommodation space 120 so that when the cover 110 is closed, the protrusion 112 protrudes from the rotation driving part 500 And presses the other side.

That is, when the cover 110 is closed, the protrusion 112 protruding from the cover 110 presses the other side of the rotation driving part 500, so that one side of the rotation driving part 500 contacts the tear bar (400) to slide in the direction of the discharge port (140).

In this embodiment, the rotation driving part 500 is formed so that one side thereof is curved upward to push the tier bar 400 from the left side.

In this way, the rotation driving part 500 according to the present invention is configured and selectively rotated by the cover 110 to adjust the sliding state of the tier bar 400. [

Of course, the protrusion 112 may be formed on the thermal head 300 rather than on the cover 110, so that the cover 110 may be pressed against the other side of the rotation driving part 500 in a closed state. It can be provided at any position.

The torsion bar 400 and the rotation driving unit 500 are driven according to an embodiment of the present invention. The rotation driving unit 500 is formed in an L shape on one side, So that an end portion of the tear bar 400 can push the right side of the tear bar 400. At this time, the other side of the rotation driving part 500 should be pressed by the protrusion 112.

Meanwhile, when the cover 110 is opened, the tier bar 400 is configured to slide in a direction opposite to the discharge port 140 and includes a separate elastic means 420 to provide a restoring force.

The elastic means 420 is configured to be slidable inwardly of the case 100 in a state in which no external force is applied to the tier bar 400. The elastic means 420 is configured to be bent in a curved shape as shown in FIG. .

The tear bar 400 is selectively bent according to a sliding state and provides a restoring force to the inside of the case 100. The tear bar 400 is rotated by the rotation driving part 500 140, the elastic means 420 is bent by the protrusion 102 protruded from the case 100.

As the elastic means 420 is bent, the tear bar 400 has a restoring force to slide to the left, which is the inner direction of the case 100. However, when the rotation driving unit 500 rotates, State is maintained.

This is because the rotation driving part 500 is kept pressed by the cover 110 and the other part of the rotation driving part 500 pushes the tier bar 400 to the right side So that the cutter 410 is exposed in the direction of the discharge port 140.

As the cover 110 is closed, the tear bar 400 slides and the cutter 410 is exposed in the direction of the discharge opening 140, so that the recording sheet can be easily cut by pressing the user.

Although not shown in the drawings, the rotary drive unit 500 according to the present invention may be configured to be symmetrical on both sides along the width direction of the recording paper in the case 100.

The rotation driving part 500 may be provided only on one side of the case 100 to slide the tier bar 400. The rotation driving part 500 may be arranged to face the inside of the case 100, And may be configured to simultaneously push the tear bars 400 in accordance with the closed state of the cover 110. [

5 and 6, a state in which the tear bar 400 is slid according to the open / closed state of the cover 110 in the thermal printer 10 according to the present invention will be described.

5 is a view showing a state in which the tier bar 400 is moved into the case 100 by the opening of the cover 110 in the thermal printer 10 of FIG. And the tier bar 400 protrudes outside the case 100 by closing the cover 110 in the printer 10.

5, when the case 100 is opened in the thermal printer 10, the tear bar 400 is slid to the left side of the case 100 due to the restoring force of the elastic means 420 So that the cutter 410 is positioned inside the case 100.

Accordingly, the tier bar 400 slides to the left so that the rotation driving unit 500 rotates counterclockwise.

In this state, since the cutter 410 is embedded in the case 100, the user can easily replace the recording paper, and it is possible to prevent the cutter 410 from being injured by the cutter 410.

6, when the cover 110 is closed and the accommodation space 120 is closed, the protrusion 112 formed on the cover 110 contacts the other side of the rotation drive part 500 And pressurized.

Accordingly, the rotation driving unit 500 rotates clockwise and one side pushes the tier bar 400 to the right. The tear bar 400 is pressed by one side of the rotation driving part 500 and slides to the right side so that the cutter 410 is exposed to the outside of the case 100.

When the cutter 410 is exposed to the outside of the case 100, the user can easily cut the recording paper using the cutter 410.

That is, as shown in FIGS. 5 and 6, the tear bar 400 slides according to the open / closed state of the cover 110, thereby controlling the exposure of the cutter 410 toward the discharge portion. Accordingly, when the user changes the recording paper, it is possible to prevent the cutter 410 from causing a scratch.

Meanwhile, in the present invention, the rotation driving part 500 is formed to be long and rotates with a rotation axis at the central part in the longitudinal direction. However, the rotation driving part 500 is formed with teeth or the like on the outer circumferential surface of the rotation driving part 500, The tear bar 400 may be pushed against the tear bar 400.

As described above, the preferred embodiments of the present invention have been described, and the present invention can be embodied in other forms without departing from the spirit or scope of the present invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the foregoing description, but may be modified within the scope and equivalence of the appended claims.
