Fig. 1 is a schematic perspective view showing a printing apparatus according to the present invention, and Fig. 2 is a schematic front view showing a printing apparatus according to the present invention.

1 and 2, the printing apparatus 100 according to the present invention is an apparatus for printing predetermined information on a recording paper, for example, an apparatus suitable for printing various labels, receipts or tickets, etc. can be

The printing apparatus 100 may be, for example, a thermal printer.

A thermal printer may be a special recording paper that responds to heat, or it may be a printer that can display text or pictures by applying heat to the recording paper with a head to develop color.

In addition, the recording paper used in the thermal printer may be a so-called linerless recording paper in which an adhesive is applied on one surface.

As shown in the drawing, the recording paper exists in the form of roll paper inside the printing apparatus 100 and then is unwound and transported to print predetermined information, but is not necessarily limited thereto. After being in a folded state from the outside, predetermined information may be printed while being unfolded and transported.

However, hereinafter, for convenience of explanation, a situation in which the recording paper exists in the form of roll paper inside the printing apparatus 100 and then is unwound and transported while printing predetermined information will be described as an example.

3 is a schematic cross-sectional view taken along line AA of FIG. 1, and FIG. 4 is a schematic perspective view showing a state in which the opening/closing part provided in the printing apparatus according to the present invention is rotated to open the inner space.

Also, FIG. 5 is a schematic enlarged view of A of FIG. 2 , and FIG. 6 is a schematic enlarged view of B of FIG. 3 .

First, if the term for the direction used below is defined before the detailed description, the upstream side and the downstream side are a relative concept to each other, and the recording paper P is first passed after being unwound based on the direction in which the recording paper P is transported. It is defined as the upstream side based on the position through which the position passes late, and the position through which the position passes late is defined as the downstream side based on the position through which it passes first.

3 to 6 , the printing apparatus 100 according to the present invention may include a main body 110 , a printing unit 120 , a recording paper separation unit 130 , and the like.

The body part 110 may include a body part 113 providing an internal space through which a recording paper P for printing predetermined information is transported, and an opening/closing part 115 for controlling the opening and closing of the internal space. can

The opening/closing part 115 may be locked to the body part 113 to close the internal space, and by releasing the locking, the opening/closing part 115 may be rotatable with respect to the body part 113 to open the internal space. can make it happen

The printing unit 120 is a component for printing predetermined information on the recording paper P transported in the inner space, and includes a head 122 for printing predetermined information by generating heat and the head ( 122) and may include a release roller 124 disposed in a position corresponding to the recording paper (P) for transferring.

The release roller 124 may be a roller containing a release agent or a roller coated with a release agent in order to prevent accumulation of the adhesive applied to one surface of the recording paper P.

The release agent may be provided as at least one material such as rubber, silicone resin, polyvinyl alcohol, paraffin, and wax.

The recording paper separation unit 130 is located on the downstream side of the printing unit 120 and cuts or cuts the recording paper P on which specific information is printed by the printing unit 120 so as to be separated from the remaining recording paper P. It may include a component, a movable part 132 and a fixed part 134 for doing so.

The movable part 132 can cut or cut the recording paper P printed with specific information passing through the corresponding position while moving in the vertical direction based on the fixed part 134, and may be a so-called guillotine type component. .

However, the recording paper separator 130 is not necessarily limited to a guillotine type, and may be implemented as a scissor type.

The main body 110 may be implemented by connection such as coupling of a plurality of components, and specific information is printed by the printing unit 120 while the recording paper P unwound in the form of roll paper is transported and the specific information is printed. A support guide 114 for supporting the recording paper P on which the specific information is printed while the recording paper P on which information is printed is transferred toward the recording paper separation unit 130 to be separated from the rest of the recording paper P. may include.

The support guide 114 may be provided between the printing unit 120 and the recording paper separation unit 130 , and may support and guide the recording paper P on which the specific information is printed.

Specifically, the support guide 114 may support the adhesive surface of the recording paper P on which the specific information is printed, and in this process, the contact area with the adhesive surface of the recording paper P is lowered to reduce the adhesive surface. A protrusion 116 may be provided to prevent the pressure-sensitive adhesive applied thereto from accumulating.

A plurality of the protrusions 116 may be formed to be spaced apart from each other along the transport direction of the recording paper P on which specific information is printed, and may be a kind of rib.

The separation distance between the protrusions 116 is not determined as a special value, and may be variously changed according to the performance of the adhesive applied to the adhesive surface.

However, when the protrusion 116 is formed too thick, a phenomenon in which the adhesive applied to the adhesive surface on the protrusion 116 accumulates may occur, so 0.5 mm to 1.5 mm may be preferable.

On the other hand, the main body 110 may include a pressing unit 117 for preventing the jam phenomenon in advance by preventing the end of the recording paper P on which the specific information is printed from being curled.

When the end of the recording paper P on which the specific information is printed is curled, the curled portion may be introduced into a space essential for the movable part 132 of the recording paper separation unit 130 to move in the vertical direction, in this case A jam phenomenon may occur in which the recording paper P is stagnant.

However, in the present invention, since the curling of the end of the recording paper P on which specific information is printed by the pressing unit 117 is prevented, the conventional jam phenomenon can be prevented.

Specifically, the recording paper P on which the specific information is printed passes through the support guide 114 to be separated from the rest of the recording paper P by the recording paper separation unit 130 while passing through the recording paper separation unit 130 and It passes through a corresponding position, and in this process, the pressing unit 117 prevents the end of the recording paper P on which the specific information is printed from being curled in one direction, so that the recording paper P on which the specific information is printed is jammed. In order to prevent the phenomenon, it is possible to press the recording paper P on which the specific information is printed, which is disposed in one direction of the support guide 114 and passes through the support guide 114 .

As shown in FIG. 5 , the pressing unit 117 has a wave shape when viewed from the side in the transport direction of the recording paper P printed with specific information, that is, from the side of the outlet DC through which the recording paper P is discharged. As possible, the curling of the end of the recording paper P can be prevented.

The pressing part 117 may press a region opposite to the adhesive surface of the recording paper P on which the specific information is printed passing between the protrusions 116 in order to prevent the above-described phenomenon.

The pressing part 117 may be formed to be rounded when the recording paper P on which specific information is printed is viewed from the side in the transport direction, that is, from the discharge port DC side through which the recording paper P is discharged. The lowest point among the formed portions may be located within the height range of the protrusion 116 .

Therefore, as described above, when the recording paper P is viewed from the outlet DC side through which the recording paper P is discharged, the pressing portion 117 has a concave portion pressed by the pressing portion 117 . It is possible to prevent the end of the recording paper P from being curled by making it round.

On the other hand, the pressing part 117 may be mounted on the opening and closing part 115 so as to be interlocked with the opening and closing part 115, whereby the internal space is opened by a change in state such as rotation of the opening and closing part 115, The degree of pressurization of the recording paper P may be adjusted by allowing the opening and closing portion 115 to be re-installed.

Here, when re-mounting of the pressing part 117 is necessary, the pressing part 117 is worn or damaged due to various factors, or when the characteristics of the used recording paper change and the degree of pressing the recording paper needs to be changed, etc. can

Even if the pressing unit 117 is not remounted to the opening/closing unit 115, the degree of pressing can be adjusted in response to the tension of the recording paper P on which the specific information is printed. For example, a material such as polyethylene terephthalate (PET), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC) and/or polyethylene (PE) may be implemented within a thickness of 0.1 mm to 1.0 mm.

When the pressing portion 117 is less than 0.1 mm, the pressing force for pressing the recording paper P is weakened due to the too thin thickness, so that the curling of the end of the recording paper P cannot be effectively prevented, and the pressing portion If 117 exceeds 1.0 mm, it is difficult to change the state, and the degree of pressing the recording paper P is too strong, which is an obstacle to smooth transfer of the recording paper P.

Therefore, the pressing unit 117 is preferably implemented within the numerical range of the material and the thickness as described above for the degree of pressing the recording paper P and smooth transfer of the recording paper P.

Meanwhile, the pressing part 117 is mounted on the opening/closing part 115 so that when the opening/closing part 115 is opened from the body part 113, it is interlocked with the opening/closing part 115 to move its position.

Here, since the head 122 of the printing unit 120 is mounted on the opening/closing unit 115 like the pressing unit 117 , it is moved in relation to the opening/closing unit 115 .

The head 122 is movably mounted on the opening and closing part 115 , which may be enabled by an elastic member such as a spring (not shown).

In other words, the head 122 prints characters or pictures on the recording paper P transferred by interaction with the release roller 124. For this, when the opening and closing part 115 closes the inner space, the It is necessary to press the release roller 124 with a certain amount of appropriate pressing force.

This is possible because the head 122 is mounted on the opening and closing part 115 to be movable by an elastic member (not shown).

Therefore, when the opening and closing part 115 is rotated from the body part 112 to open the inner space, the head 122 is slightly protruded by the restoring force of an elastic member (not shown).

When the opening and closing part 115 is rotated from the body part 112 , the head 122 protrudes above the lowest point of the pressing part 117 , and when the internal space is closed by the opening and closing part 115 again, the By the release roller 124, the position is moved within the lowest point of the pressing unit 117, so that the pressing unit 117 presses the recording paper P.

Of course, the downstream second support part 103 (refer to FIG. 16), which will be described with reference to FIG. 16, is also connected to the head 122 and can be mounted movably on the opening and closing part 115 like the head 122. , due to this, when the opening and closing part 115 is rotated from the body part 112, it may protrude beyond the lowest point of the pressing part 117, and when the internal space is closed by the opening and closing part 115, the pressing part ( 117), the position is moved within the lowest point, so that the pressing unit 117 presses the recording paper P.

7 is a schematic perspective view showing the cover provided in the printing apparatus according to the present invention separated.

Referring to FIG. 7 , the printing apparatus 100 according to the present invention may include a body part 110 including a body part 113 and an opening/closing part 115 as described with reference to FIGS. 1 to 6 . have.

The body part 113 is mounted on the frame part 111 so as to cover the frame part 111 providing the overall appearance of the printing apparatus 100 according to the present invention, and the recording paper separation part 130, so that the printing part ( 120) may include a cover part 112 for providing an outlet DC through which the recording paper P printed with specific information is discharged to the outside.

The cover part 112 may be detachably mounted to the frame part 111, and may include a protrusion 119 for preventing the adhesive deposited on the opposite side of the adhesive surface of the recording paper P from accumulating. can

Hereinafter, the reason why the adhesive is deposited on the opposite side of the adhesive surface of the recording paper P and the protrusion 119 will be described in detail, but the protrusion 119 is the protrusion 116 described with reference to FIGS. 1 to 6 . It should be clearly stated that and the formation location are different components.

8 is a schematic front view illustrating a cover provided in the printing apparatus according to the present invention, and FIG. 9 is a schematic bottom perspective view illustrating the cover provided in the printing apparatus according to the present invention.

Also, FIG. 10 is a schematic cross-sectional view taken along line BB of FIG. 8 , and FIG. 11 is a schematic cross-sectional view taken along line CC of FIG. 8 .

8 to 11 , the cover unit 112 is on the opposite side of the adhesive surface while the recording paper P on which specific information is printed by the printing unit 120 is discharged to the outside through the outlet DC. A protrusion 119 may be provided to prevent the deposited adhesive from accumulating.

Here, the phenomenon in which the adhesive is deposited on the opposite side of the adhesive surface of the recording paper P is related to the fact that the recording paper P is provided in the form of a roll paper.

That is, since the recording paper P is provided in the form of roll paper, the opposite side of the adhesive surface is inevitably provided in contact with the adhesive surface, and thus the opposite side of the adhesive surface of the recording paper P is applied to the adhesive surface. A case in which the adhesive is unwound and transported may occur.

Of course, the opposite side of the adhesive surface is coated, but the coating does not completely block the adhesion of the adhesive.

For the above reasons, the printing apparatus 100 according to the present invention includes a configuration for preventing the accumulation of adhesive on the components that come into contact with the opposite surface of the adhesive surface, and one of them is the protrusion 119 . .

A plurality of the protrusions 119 may be formed to be spaced apart from each other along the discharge direction of the recording paper P on which specific information is printed, and may be a kind of rib.

The cover part 112 includes a first outlet providing part 112a to provide a first outlet DC1 for discharging recording paper having a first width among the outlets DC, and a first outlet providing part 112a having a width different from the first width. A second outlet providing unit 112b for discharging recording paper having two widths may be provided.

For example, the second width may be greater than the first width, the first width may be 1.5 inches, and the second width may be 4 inches.

The first outlet providing part 112a may be present in the second outlet providing part 112b.

The first outlet providing part 112a may provide a height in the vertical direction of the first outlet DC1 higher than the height in the vertical direction of the second outlet DC2, which is a user's finger. This is so that the recording paper having the first width partially inserted and printed with specific information can be drawn out by gripping it.

In other words, when the first width is 1.5 inches, the length of the recording paper on which the specific information cut or cut by the recording paper separation unit 130 is printed is generally small, which causes it to be discharged through the first outlet DC1. In this case, it may be difficult to easily grip the discharged part as a user.

For the same reason as described above, in the case of recording paper having the first width, there may be a case in which the user has to put a finger into the first outlet DC1 to grip it and then pull it out. The first outlet providing part 112a is provided so that the height of the second outlet DC2 is higher than the vertical height of the second outlet DC2.

Meanwhile, the protrusion 119 may be formed in the first outlet providing part 112a and the second outlet providing part 112b, and the protrusion 117 formed in the first outlet providing part 112a is formed on both sides. The separation degree of the part is formed to be larger than the separation degree of the central part, so that it is possible to facilitate the insertion of the user's finger.

The protrusion 117 formed in the first outlet providing part 112a may be formed to be inclined downward along the discharge direction of the recording paper on which the specific information is printed, as shown in FIG. It is possible to prevent the end of the printed paper having the first width from being curled in one direction and from being inserted into the space (SS1, see FIG. 12 ) for the operation of the recording paper separation unit 130 .

The end of the recording paper of the first width on which the specific information is printed may be curled in one direction for reasons such as material characteristics and/or provided in the form of roll paper, but the end of the first outlet is formed to be inclined downward along the discharge direction While sliding along the providing portion 112a, it is prevented from being rolled, and at the same time, it can be prevented from being inserted into the space SS1 for the operation of the recording paper separation unit 130 .

In addition, as shown in FIG. 10(b), the protrusion 117 formed in the first outlet providing part 112a is formed to be inclined downward along the discharge direction of the recording paper on which the specific information is printed, and is rounded to have an inflection point. may be formed.

When the protrusion 117 is formed to be rounded to have an inflection point, it is possible to slide more smoothly while the ends are in contact, thereby preventing a phenomenon in which the recording paper of the first width on which the specific information is printed is stagnated during transport. At the same time, it is possible to prevent the phenomenon of drying in advance.

In addition, when the protrusion 117 is formed to be rounded to have an inflection point, a space between the first outlet providing part 112a and one surface SF of the frame part 111 opposite to that is secured, and the specific information is printed. It is possible to ensure the smooth transfer of the recording paper of the first width.

On the other hand, the protrusion 118 formed in the second outlet providing part 112b may be formed so that the separation degree of both sides is smaller than the separation degree of the other parts, so that the recording paper of the second width printed with specific information It is possible to prevent the both ends of the ends of the blades from being rolled up and being inserted into the space between them.

In other words, the protrusion 118 formed in the second outlet providing part 112b is formed so that the separation degree of both sides is smaller than that of the other parts, so that the separation space can be reduced, and the specific information is printed. Even if both ends of the end of the recording paper of the second width are slightly curled, it is not inserted into the small space.

In addition, although not shown, the spacing of the protrusions 118 formed in the second outlet providing part 112b is less than the spacing of the protruding parts 117 formed in the first outlet providing part 112a, and the specific information It is also possible to prevent both ends of the ends of the printed paper from being curled and inserted into the space existing therebetween.

The protrusion 118 formed in the second outlet providing part 112b is inclined downward along the discharge direction of the recording paper on which the specific information is printed, as shown in FIG. It is possible to prevent the end of the paper from being curled in one direction and at the same time prevent it from being inserted into the space SS1 for the operation of the recording paper separation unit 130, and the reason is along the discharge direction of the recording paper shown in FIG. Since it is the same as the protrusion 117 formed in the first outlet providing portion 112a formed to be inclined downward, a detailed description thereof will be omitted.

In addition, the protrusion 118 formed in the second outlet providing part 112b is formed to be inclined downward along the discharge direction of the recording paper on which the specific information is printed, as shown in FIG. Since the effect is the same as the protrusion 117 formed in the first outlet providing part 112a shown in FIG. 10(b), a detailed description thereof will be omitted.

12 is a schematic front view illustrating a first modified example of the cover provided in the printing apparatus according to the present invention, and FIG. 13 is a schematic enlarged view of FIG. 2A to which the first modified example of the cover is applied.

12 and 13, the cover part 112' according to the first modified example is shown in FIGS. 8 to 11 except for the protrusion 118' formed in the second outlet providing part 112b'. Since the configuration and effect are the same as those of the cover part 112 described with , descriptions other than the protrusion 118' formed in the second outlet providing part 112b' will be omitted.

The protrusion 118 ′ formed in the second outlet providing part 112b ′ may not be uniformly protruded toward one surface SF of the opposite frame part 111 .

For example, the degree to which at least one of the protrusions 118 ′ formed in the second outlet providing part 112b ′ protrudes toward one surface SF of the frame part 111 opposite to that of the other protrusions 118 ′ is determined. It may be larger, and as shown in the drawing, at least one of the protrusions 118 ′ formed on both sides may correspond to this.

The protrusion 1118' with a greater degree of protrusion is preferably at least one of the protrusions located inside the outermost protrusion 1119' among the protrusions 118' formed in the second outlet providing part 112b'. It is preferable that there is only one, and as a result, the inside of both ends of the end of the recording paper on which specific information is printed is pressed relatively more strongly, effectively preventing the both ends from being rolled up and inserted into the space existing therebetween. can

On the other hand, the protrusion 1118' having a larger protrusion degree is preferably located between the protrusions 1111' formed on the one surface SF of the frame part 111 opposite to each other. A space to ensure smooth transport is secured.

14 is a schematic front view showing a second modified example of a cover portion provided in the printing apparatus according to the present invention.

Referring to FIG. 14 , the cover part 212 according to the second modified example includes a first outlet providing part 212a that provides a first outlet DC1 for discharging recording paper having a first width among the outlets DC. ), a second outlet providing portion 212b for providing a second outlet DC2 for discharging recording paper having a second width greater than the first width, and a third width greater than the second width A third outlet providing unit 212c for providing a third outlet DC3 for discharging recording paper may be provided.

Here, the second outlet providing part 212b may exist in the third outlet providing part 212c, and the first outlet providing part 212a may include the second outlet providing part 212b and the third outlet It may be present in the providing unit 212c.

The first outlet providing part 212a may provide a height in the vertical direction of the first outlet DC1 higher than the height in the vertical direction of the second outlet DC2, which is a user's finger. This is so that the recording paper having the first width partially inserted and printed with specific information can be drawn out by gripping.

In addition, the second outlet providing unit 212b may provide a height in the vertical direction of the second outlet DC2 higher than that of the third outlet DC3 in the vertical direction. This is to allow the user to grip and withdraw the recording paper having the second width on which a finger is partially inserted and printed with specific information.

On the other hand, the protrusion 1212c formed in the third outlet providing part 212c may have a smaller spacing than the protruding part 1212b formed in the second outlet providing part 212b, so that the recording paper having a third width It is possible to prevent the both ends of the ends of the blades from being rolled up and being inserted into the space between them.

Here, the separation distance L1 between the protrusions 1212c formed in the third outlet providing part 212c may be in the range of 0.3 mm or more and 0.6 mm or less.

When the separation distance L1 is less than 0.3 mm, the interval becomes too small, and there is a problem in that the probability of a defect during manufacturing by injection increases.

In addition, when the separation distance L1 is less than 0.3 mm, the number of the protrusions 1212c increases, so that the contact area with the opposite side of the adhesive side of the recording paper increases, causing problems such as the accumulation of the adhesive. do.

When the separation distance exceeds 0.6 mm, there is a high probability that the ends of the recording paper are curled up at the interval therebetween, which may cause a problem in smooth transfer of the recording paper.

Meanwhile, the distance L2 between the innermost protrusion and the outermost protrusion among the protrusions 1212c formed in the third outlet providing part 212c may be in the range of 0.9 mm or more and 18 mm or less.

When the distance L2 is less than 0.9 mm, there is a limitation in the application range of the recording paper of the third width, and there is a problem in that the application range of the printing apparatus according to the present invention is lowered, and when it exceeds 1.8 mm, the protrusion ( 1212c) increases, so that the contact area with the opposite side of the adhesive side of the recording paper increases, resulting in problems such as the accumulation of the adhesive.

On the other hand, it was found that the configuration for the separation distance L1 and the distance L2 described above can be equally applied to the protrusion 118 formed in the second outlet providing part 112b described with reference to FIGS. 8 to 11 . put

15 is a schematic enlarged view of B of FIG. 3 .

15, one surface (SF) of the frame part 111 opposite to the first outlet providing part 112a and the second outlet providing part 112b is a guide support part ( 114) may be provided with a stepped height ST when compared to one surface.

This is because the end of the recording paper on which the specific information is printed is curled in one direction while the recording paper on which the specific information is printed is transported toward the recording paper separation unit 130 to be separated from the rest of the recording paper, so that the end is separated from the recording paper separation unit. It can be prevented from being inserted into the essential space (SS2) for the operation of the (130).

If the stepped height ST is not implemented but is implemented at the same height, the possibility that the end of the recording paper on which the specific information is printed, rolled in one direction will be inserted into the essential space SS2 increases, which eventually leads to a jam phenomenon It will inevitably cause problems.

The stepped height ST is preferably formed within the range of 1 mm or more and 10 mm or less, and if the stepped height ST is less than 1 mm, the specific information is inserted into the essential space SS2 at the end of the printed paper If it exceeds 10 mm, the end of the recording paper on which the specific information is printed provides a space to be curled by itself, and it may be impossible to smoothly transfer the recording paper on which the specific information is printed in an unfolded state. .

When the step height ST exceeds 10 mm, the space between the first outlet providing part 112a and the second outlet providing part 112b and the frame part 111 increases, so that this space is Since the end of the recording paper on which the specific information is printed functions as a space where it is curled by itself, it is preferable that the step height ST be formed to be 10 mm or less.

16 is a schematic enlarged cross-sectional view of FIG. 3C.

Referring to the preceding drawings and FIG. 13 , the main body 110 includes a first support part 101 for supporting an adhesive surface while the recording paper is transported in the internal space, and a second support part for supporting the opposite surface of the adhesive surface. 104 and a third support 108 .

Here, the second support part 104 may include a protrusion 105 for reducing the contact area with the opposite surface of the adhesive surface to prevent the adhesive deposited on the opposite surface of the adhesive surface from accumulating.

A plurality of the protrusions 105 may be formed to be spaced apart from each other along the transport direction of the recording paper P on which specific information is printed, and may be a kind of rib.

The separation distance between the protrusions 105 is not determined as a special value, and may be variously changed according to the performance of the adhesive applied to the adhesive surface.

However, if the protrusion 105 is formed too thick, a phenomenon in which the adhesive applied to the adhesive surface on the protrusion 105 is accumulated may occur. Since a line may be formed by abrasion, 0.5 mm to 1.5 mm may be preferable.

On the other hand, it is clearly stated that the protrusion 105 is a different component from the protrusions 116 and 119 described in the previous embodiment.

The second support portion 104 may include an upstream second support portion 102 and a downstream second support portion 103 respectively positioned on an upstream side and a downstream side with respect to the head 122 .

Here, the protrusion 105 may be formed on at least one of the upstream-side second support portion 102 and the downstream-side second support portion 103 .

The upstream side second support unit 102 has an upstream end 1021 formed in a rounded shape or inclined so as to provide a space S1 for accumulating the adhesive on the opposite side of the adhesive surface during the transfer of the recording paper. It may be formed in a shape. The recording paper comes into contact with the boundary portion of the upstream end 1021 as it is transported, and in this process, the adhesive on the opposite surface is accumulated in the space S1, so that the adhesive is not accumulated on other components This prevents deterioration of printing performance.

Here, the upstream end 1021 must have a large area in contact with the opposite surface of the recording paper to increase the accumulation of the adhesive on the opposite surface. For this reason, the upstream end 1021 has the protrusion 105 formed It may be a non-formed area that does not become visible.

In other words, the protrusion 105 may be formed only in a part of the upstream second support portion 102 .

On the other hand, the upstream side second support unit 102 may be coated with a release agent provided with at least one material such as rubber, silicone resin, polyvinyl alcohol, paraffin and wax to minimize the accumulation of the adhesive on the opposite surface. have.

The upstream second support part 102 may be implemented by bonding the surface of the second support part 102 with a tape containing a release agent component in addition to the method of coating with a release agent as described above in order to minimize the accumulation of the adhesive on the opposite surface, in this case The upstream end 1021 is a region where the surface is not joined with a tape containing a release agent component - the release agent component may include at least one component such as rubber, silicone resin, polyvinyl alcohol, paraffin and waxes. can be

In addition, the upstream-side second support part 102 may be implemented with a material containing a release agent itself - the release agent may include at least one of rubber, silicone resin, polyvinyl alcohol, paraffin, and waxes. In this case, the upstream end 1021 may be implemented with a material other than the release agent.

Here, since the upstream end 1021 is a part that requires the accumulation of adhesive, an uncoated area that is not coated with the release agent, an area where the surface is not bonded with a tape containing the release agent component, or a material that does not contain a release agent component is implemented It may be a region to be used, which is the region coated with the release agent, the region to which the surface is joined with the tape containing the release agent component, or the region implemented with the material containing the release agent component of the upstream second support part 102 . It could mean that it could be part of it.

The upstream second support part 102 may be roughened by a method such as corrosion to minimize the accumulation of the adhesive on the opposite surface, apart from being coated with the release agent, thereby forming fine irregularities on the surface. A degree of surface roughness may be large.

However, since the upstream end 1021 is a portion that requires the accumulation of the adhesive, it may be an area that is not roughly formed, and the rough formed area may be a part of the upstream second support unit 102 .

On the other hand, the upstream end 1021 has a third supporting part that supports the opposite surface and is present upstream from the upstream end 1021 so as to facilitate the accumulation of the adhesive deposited on the opposite surface in the space S1 . It may be located below the lowest point of 108 and the lowest point of the head 122 .

Due to this, the degree of contact with the boundary portion of the upstream end 1021 is increased in the process of transferring the recording paper, and the possibility that the adhesive on the opposite surface is accumulated in the space S1 is further increased.

The downstream end 1022 of the upstream second support unit 102 is cut or cut out of the recording paper by the recording paper separator 130, and the remaining recording paper is backfeeding - the backfeeding is cut to minimize the blank space of the recording paper. Or means to be transported to the inner space after cutting - to be formed in a rounded shape or a slope shape so as to provide a space (S2) for accumulating the adhesive on the other side of the adhesive side of the remaining recording paper in the process can

The remaining recording paper comes into contact with the boundary portion of the downstream end 1022 while being back-feeded, and in this process, the pressure-sensitive adhesive on the opposite side of the adhesive surface of the remaining recording paper is accumulated in the space S2, thereby The pressure-sensitive adhesive does not accumulate on other components, thereby preventing deterioration of printing performance.

Here, the downstream end 1022 must have a large area in contact with the opposite surface of the recording paper to increase the accumulation of the adhesive on the opposite surface. For this reason, the downstream end 1022 has the protrusion 105 formed It may be a non-formed area that does not become visible.

In other words, the protrusion 105 may be formed only in a part of the upstream second support portion 102 .

On the other hand, as described above, the upstream second support part 102 is a mold release provided with at least one material such as rubber, silicone resin, polyvinyl alcohol, paraffin and wax to minimize the accumulation of the adhesive on the opposite surface. It may be coated with zero agent, the surface may be bonded with a tape of a release agent component, or may be formed of a material containing a release agent.

However, since the downstream end 1022 is a part that requires the accumulation of adhesive, an uncoated area that is not coated with the release agent, an area where the surface is not joined with a tape containing the release agent component, or a material that does not contain a release agent component It may be an area where the release agent is coated, the area where the surface is bonded with the tape containing the release agent component, or the area implemented with a material containing the release agent component is a part of the upstream second support part 102 It could mean that it could be.

The upstream-side second support unit 102 is coated with the release agent, adhered to a tape containing a release agent component, or corroded to minimize the accumulation of the adhesive on the opposite surface separately from being implemented with a material containing a release agent component. It may be formed to be rough by the method of

However, since the downstream end 1022 is a part that requires the accumulation of the adhesive, it may be a region that is not roughly formed, and the region that is roughly formed may be a part of the upstream second support portion 102 .

On the other hand, the downstream end 1022 has a third supporting part ( It may be located in a lower direction than the lowest point of 108 and the lowest point of the head 122 .

Due to this, the degree of contact with the boundary portion of the downstream end 1022 is increased in the process of backfeeding the recording paper, and the possibility that the adhesive on the opposite surface is accumulated in the space S2 further increases, and vice versa. Even in the process of forward feeding of the recording paper, the degree of contact with the boundary portion of the downstream end 1022 is increased, so that there is a high possibility that the adhesive on the opposite surface is accumulated on the upstream side of the downstream end 1022 .

The downstream end 1032 of the second downstream support 103 is cut or cut by the recording paper separator 130, and in the process of backfeeding the remaining recording paper, it is on the opposite side of the adhesive surface of the remaining recording paper. In order to provide a space S3 for the accumulated adhesive to be deposited, it may be formed in a round shape or a slope shape.

The remaining recording paper comes into contact with the boundary portion of the downstream end 1032 while being back-feed, and in this process, the pressure-sensitive adhesive on the opposite side of the adhesive surface of the remaining recording paper is accumulated in the space S3, which causes the pressure-sensitive adhesive is not accumulated on other components, thereby preventing deterioration of printing performance.

Here, the downstream end 1032 must have a large area in contact with the opposite surface of the recording paper to increase the accumulation of the adhesive on the opposite surface. For this reason, the downstream end 1032 has no protrusion 105. It may be a non-formed area.

In other words, the protrusion 105 may be formed only in a part of the downstream-side second support 103 .

On the other hand, the downstream second support 103 may be coated with a release agent provided with at least one material such as rubber, silicone resin, polyvinyl alcohol, paraffin, and wax to minimize the accumulation of the adhesive on the opposite surface. have.

The downstream-side second support part 103 may be implemented by bonding the surface of the second support part 103 with a tape containing a release agent component in addition to the method of coating with a release agent as described above in order to minimize the accumulation of the adhesive on the opposite surface, in this case The downstream end 1032 is an area where the surface is not joined with a tape containing a release agent component - the release agent component may include at least one component such as rubber, silicone resin, polyvinyl alcohol, paraffin and waxes. can be

In addition, the upstream-side second support part 102 may be implemented with a material containing a release agent itself - the release agent may include at least one of rubber, silicone resin, polyvinyl alcohol, paraffin, and waxes. In this case, the upstream end 1021 may be implemented with a material other than the release agent.

However, since the downstream end 1032 is a part that requires the accumulation of adhesive, an uncoated area that is not coated with the release agent, an area where the surface is not joined with a tape containing the release agent component, or a material that does not contain a release agent component is implemented The region to be coated with the release agent, the region to which the surface is bonded with the tape containing the release agent component, or the region implemented with a material containing the release agent component is a part of the downstream second support part 103 It could mean that it could be.

The downstream second support part 103 is coated with the release agent, adhered to a tape containing a release agent component, or corroded, etc. It may be formed to be rough by the method of

However, since the downstream end 1032 is a portion that requires the accumulation of the adhesive, it may be an area that is not roughly formed, and the rough formed area may be a part of the downstream second support portion 103 .

On the other hand, the head 122 of the printing unit 120 is at least partially coated with the above-described release agent to prevent the pressure-sensitive adhesive on the opposite side of the pressure-sensitive adhesive surface from accumulating while the recording paper is transported in the inner space and contains a release agent component. One tape may be implemented with a material including an adhesive or a release agent component, and areas other than the heating line may be coated with the release agent, and may be implemented with a material including an adhesive or a release agent component with a tape containing a release agent component.

The non-coating method for the heating line may be implemented through various masking materials such as masking tape and various masking methods.
