Here, if the terms for the upstream side and the downstream side are defined, the position where the recording sheet R0 fed out of the roll paper R and fed first is the upstream side, and the recording sheet R0 passing the upstream side passes later The downstream side.

When the terms for the first recording sheet R1 and the second recording sheet R2 are defined, the first recording sheet R1 and the second recording sheet R2 are both recorded on the recording sheet R0, The first recording sheet R1 is one area of the recording sheet R0 that is printed first by the printing unit 20 than the second recording sheet R2 and the second recording sheet R2 is a region of the first recording sheet R2 Lt; RTI ID = 0.0 > R1. ≪ / RTI >

The recording paper cutting device 30 essentially has a first cutting part 310 for cutting between the first recording sheet R1 and the second recording sheet R2 which are shifted in mutually approaching directions or mutually spaced directions and passing between the first and second recording sheets R1 and R2 And a second cutting unit 320. The second cutting unit 320 includes a first cutting unit 320 and a second cutting unit 320. [

For example, the first cutting portion 310 may be a movable cutter that is movable toward the second cutting portion 320, and the second cutting portion 320 may be a movable cutter for moving the first cutting portion 310 It can be a fixed cutter.

However, it is noted that the second cutting unit 320 may be implemented as a movable cutter, and the first cutting unit 310 may be implemented as a fixed cutter, both of which may be implemented as a movable cutter.

Hereinafter, the first cutting portion 310 is a movable cutter and the second cutting portion 320 is a fixed cutter.

The first cutting portion 310 may be disposed to be movable in a case 306 mounted in an internal space S1 provided by the main body portion 10, And may include a first case 302 and a second case 304 to provide an installation space S2 in which the cutting portion 310 is installed.

The second case 304 may be a kind of cover member for the first case 302, and all known methods may be used for the fastening method.

At least one or more other components may be disposed on the first case 302 together with the first cutting unit 310. Specifically, the first cutting unit 310 may be provided with a driving force for moving the first cutting unit 310 At least one driving force transmitting portion G rotating by the driving force providing portion D may be disposed.

The driving force providing portion D may be a kind of step motor, and the rotational axis I of the driving force providing portion D may be disposed in the installation space S1.

The first gear G1 may be mounted on the rotating shaft I and the first gear G1 may be rotated in conjunction with the rotation of the rotating shaft I. [

The first gear G1 may be connected to a driving force transmitting portion G that rotates by the driving force so that a driving force of the driving force providing portion D is transmitted to the first cutting portion 310. [

The driving force transmitting portion G is a gear assembly including a plurality of gears and includes a second gear G2 meshing with the first gear G1 and a third gear G3 meshing with the second gear G2 ).

The second gear G2 includes a second-first gear G2-1 that meshes with the first gear G1 and a second-second gear G2-2 that meshes with the third gear G3 .

The diameter of the second-first gear G2-1 and the diameter of the second-second gear G2-2 may be different from each other. For example, May be larger than the diameter of the second-second gear G2-2.

The difference in diameter between the first gear G1, the second-first gear G2-1, the second-second gear G2-2, and the third gear G3 is determined by the difference D of the third gear G3 by the driving force provided by the first cutting unit 310 and the second gear G2 by the driving force, In consideration of the reduction ratio related to the degree of the positional shift of the gears.

The position of the first cutting portion 310 may be related to the rotation angle of the third gear G3. The driving force transmitting portion G of the third gear G3 may have an eccentric portion E projecting eccentrically on the bottom surface thereof.

The first cutting part 310 has a deflection part H which is formed to be deviated from the center and receives the eccentric part 310 so that the rotation of the eccentric part E, In a direction approaching and spaced apart from the base 320.

Specifically, when the third gear G3 is rotated by the driving force of the driving force providing portion D, the eccentric portion E protruding eccentrically rotates, and thereby the eccentric portion E The first cutting unit 310 performs a linear motion by the deflecting unit H.

The eccentric part E may be provided with a rigid beam guiding steel part 308 for reinforcing the rigidity of the eccentric part E and substantially the rigid beam guiding part 308 mounted on the eccentric part E may be provided with a biasing Is inserted into the portion (H).

Therefore, when the eccentric portion E rotates with the rotation of the third gear G3, the stiffness-conservation-strength portion 308 directly contacts the deflection portion H, so that the durability E of the eccentric portion E Can be increased.

7 to 10 are views for explaining the process of cutting the recording sheet by the recording sheet cutting apparatus provided in the printing apparatus according to the present invention. Fig. 3 is a schematic perspective view showing a cutting portion. Fig.

The first cutting portion 310 is moved in the direction of approaching the second cutting portion 320 in the installation space S2 of the first case 302 by the rotation of the third gear G3 It is possible to cut between the first recording sheet R1 and the second recording sheet R2 as shown in FIG. 10, but it is also possible to cut between the first recording sheet R1 and the second recording sheet R2 A perforated line may be formed.

Whether or not the perforated line is formed or cut between the first recording sheet R1 and the second recording sheet R2 depends on the degree to which the first cutting unit 310 is moved toward the second cutting unit 320 And will be described in detail below.

Referring to FIG. 7, the first cutting unit 310 may have a substantially V shape. When the first cutting unit 310 approaches the second cutting unit 320, And cut between the second recording sheets R2 toward the center from both ends in the width direction.

The cutting guide portion 308 may be formed at both ends of the first cutting portion 310 to be upwardly inclined along a direction approaching the second cutting portion 320. The cutting guide portion 308 may be formed, May be a component that first contacts the second cutting unit 320 when the first cutting unit 310 approaches the second cutting unit 320.

When the first cutting unit 310 approaches the second cutting unit 320 to cut between the first recording sheet R1 and the second recording sheet R2 as shown in FIG. 8, The bottom of the first cutting portion 310 may be inclined upwards toward the direction of approaching the second cutting portion 320 by the contact with the second cutting portion 320, This is because it is located below the upper surface of the portion 320.

In other words, when the first cutting portion 310 approaches the second cutting portion 320, the cutting guide portion 308 first comes into contact with the second cutting portion 320, 1 cutting portion 310 is naturally moved upwardly inclined along the upper surface of the second cutting portion 320.

In the meantime, the recording paper cutting apparatus 30 according to the present invention is configured such that the first cutting unit 310 is moved upward toward the direction of approaching the second cutting unit 320 while being in contact with the second cutting unit 320 And a pressing force providing unit 330 for applying a pressing force to the first cutting unit 310 so that the first cutting unit 310 is moved in an inclined position.

The pressing force providing portion 330 includes a contact portion 332 contacting the first cutting portion 310 and an elastic portion 334 pressing the contact portion 332 to contact the first cutting portion 310, And may further include a position movement guide portion 336 for guiding the movement of the contact portion 332 (see FIG. 5).

Specifically, the position movement guide part 336 can be fixed to the second case 304, and the elastic part 334, which is a kind of spring, can be inserted to support the elastic part 334, The contact portion 332 can be moved up and down along the position movement guide portion 336.

The contact portion 332 can maintain the contact state with the first cutting portion 310 by the elastic portion 334 mounted on the position movement guide portion 336, When the first cutting portion 310 is elastically deformed when the first cutting portion 310 contacts the second cutting portion 320 and the contact is released after the first cutting portion 310 is contacted with the second cutting portion 320, The contact between the contact portion 332 and the first cutting portion 310 can be maintained by the restoring force due to the elastic deformation.

As described above, when the first cutting portion 310 is moved toward the second cutting portion 320 to cut between the first recording sheet R1 and the second recording sheet R2, the pressing force The first cutting part 310 and the second cutting part 320 may be moved up and down in a state of being in contact with the second cutting part 320 by the feeder 330. As a result, The contact pressure is applied and the accuracy of cutting can be assured.

The recording paper cutting apparatus 30 according to the present invention senses whether the first cutting unit 310 is moved or not and determines whether the first cutting unit 310 and the second cutting unit 320 (See FIGS. 4 and 5) for acquiring information on whether or not the first recording sheet R1 and the second recording sheet R2 are cut.

The position movement sensing unit 340 may be a kind of sensing object sensed by the sensor 301 mounted on the upper surface of the first case 302 and conversely the sensing object may be mounted on the upper surface of the first case 302 The position movement sensing unit 340 may be a sensor.

When the third gear G3 is rotated by the driving force of the driving force providing portion D so that the first cutting portion 310 performs a straight movement toward the second cutting portion 320, The first recording sheet R1 and the second recording sheet R2 are cut.

This is the case where the first cutting portion 310 is moved to a position exceeding the perforated line forming space S3 toward the second cutting portion 320 as shown in FIG. 10, When the first cutting portion 310 is moved toward the second cutting portion 320 only before the perforated line forming space S3 or is moved without completely exceeding the perforated line forming space S3, A perforated line may be formed between the first recording sheet R1 and the second recording sheet R2.

The perforated line forming space S3 may be formed in the center of the first cutting unit 310 as a kind of space provided in the first cutting unit 310. [

Whether the first recording sheet R1 and the second recording sheet R2 are cut or whether a perforated line is formed between the first recording sheet R1 and the second recording sheet R2 is determined based on whether the third gear G3 And may be appropriately controlled by a control unit (not shown).

On the other hand, a recording sheet that can be used for a printing apparatus may be a recording sheet coated with an adhesive on one side thereof, and an adhesive applied to one side of the recording sheet serves as a factor for lowering the cutting performance.

Here, one surface of the recording sheet to which the adhesive is applied may be one surface facing the fixed cutter.

The movable cutter and the stationary cutter used in the printing apparatus are polished at opposite angles, and the edges formed at the opposite angles are abutted against each other to cut the recording paper.
