Description

The present invention is excellent in environmental friendliness by making everything except the label tape, which is the content, made of flammable paper, simplifies the assembly procedure, and can reduce the cost. Furthermore, the label printer can be used. It relates to a paper cartridge that can share a case with a plurality of tape widths in the above-mentioned applications.

In Patent Documents 1 to 3, in consideration of environmental pollution at the time of disposal and manufacturing cost, in a cartridge containing a strip-shaped (ribbon-shaped) printing medium, the printing medium is stored in a paper case, and the printing medium is described. A case with shared parts that can be used for different widths has been proposed.

Patent Document 1 (Japanese Patent No. 301248) describes a lid of a cartridge containing a so-called fabric ribbon, a paper cassette body (hereinafter referred to as a case) having a U-shaped cross section with a bottom piece and a side piece, a tension member, and a tension. A configuration is disclosed in which the receiving member is made of paper in consideration of environmental pollution at the time of disposal.

In Patent Document 2 (Japanese Patent Laid-Open No. 7-6497) and Patent Document 3 (Japanese Patent Laid-Open No. 2017-56711), at least the outer height dimension of the case of the cartridge containing the label tape is uniform regardless of the tape width type. A plate-shaped auxiliary plate (hereinafter referred to as a spacer) having a leg that stands up against the inner bottom surface of the case for changing the height position of the label tape in the case according to the tape width type is provided. A configuration is disclosed in which a label tape is provided on the spacer to form a case as a common member.

However, in Patent Document 1, since the fabric ribbons are stored in a state of being assembled inside the case, the case is crushed or deformed by a slight pressure from the upper and lower surfaces of the case, that is, the tape width direction. There was something. If the aggregated part of the fabric ribbon in particular of the case is deformed, the fabric ribbon may be broken or distorted and sent out, or in the worst case, the fabric ribbon may not be sent out normally.

Further, in Patent Documents 2 and 3, the label tape is placed on the upper surface of the spacer having different leg lengths depending on the tape width type. Therefore, when the spacer and the leg are made of paper, the label is placed on the spacer. The weight of the tape will be applied and it will bend or be distorted.

Hereinafter, a so-called label tape cartridge having many types of tape widths will be described. In short, it has been proposed to make a case of a cartridge having external dimensions corresponding to the types of tape widths made of paper. However, there is a problem that it is wasteful to prepare a large number of paper cases having different external dimensions corresponding to the tape width type. In addition, due to the fact that the case of the cartridge is made of paper, the pressing force of the impulsive member provided to stabilize the position of the label tape in the height direction on the printer side, especially the pressing force that differs depending on the tape width, There was a problem that it might not be able to withstand.

On the other hand, even in the past, the external dimensions of the cartridge should be uniform, and the height position of the label tape should be adjusted by placing it on spacers with different leg lengths (heights) in the case of the cartridge according to the tape width type. Was proposed. However, this configuration is based on the premise that a material with sufficient strength, such as plastic, is used, and if it is made of paper, it is strong at the part where contact or connection such as engagement with the printer side occurs. Due to a shortage, the legs, auxiliary plates, etc. may be deformed, distorted, or crushed.

Patent Registration No. 301214 Japanese Unexamined Patent Publication No. 7-6497 Japanese Unexamined Patent Publication No. 2017-56711

The problem to be solved by the present invention is that the conventional tape cartridge is made entirely of paper except for the label tape, which is the content, in consideration of environmental pollution at the time of disposal and the manufacturing cost, and the width of the printing medium. It was not possible to achieve both a configuration that can handle types.

In order to solve the above problems, the present invention houses a label tape in which a printing medium is laminated on one surface of a strip-shaped base material, and stores the label tape in a state of being wrapped around the label tape. A paper case having an insertion opening for inserting a shaft body projecting to the side into the winding center of the label tape, and a height in the upper surface-bottom surface direction in the case are divided into upper and lower sides. An upper spacer piece, which has a partition surface having substantially the same dimensions as the inside dimension of the case in a plan view, and is provided in pairs on the facing edge portions of the partition surface to secure an upper space in the case. Paper having at least the lower spacer piece among the lower spacer pieces provided in pairs on the facing edge portions adjacent to the upper spacer piece on the partition surface to secure the lower space in the case. The spacer is provided with a spacer made of paper, and the main feature of the spacer is to position the label tape on the lower side of the partition surface and to arrange the label tape in the case so that the upper spacer piece can be seen through the delivery opening of the case. And said.

In the present invention, the case can be made from one sheet of paper material having a delivery opening and an insertion opening, and the spacer is also made by bending the lower spacer piece and the upper spacer piece around the partition surface from one sheet of paper material. It has the advantage of being easy to assemble because it can be created.

Further, in the present invention, the wrapped label tape is positioned under the partition surface of the spacer in the case, and the movement of the label tape from the upper surface to the bottom surface is restricted by the partition surface and the inner bottom surface of the case. Here, since the label tape is placed on the inner bottom surface of the case that is in a stable state at the printer mounting site, that is, because it is located below the partition surface, there is little movement of the label tape from the top surface to the bottom surface. Can be stabilized.

Further, in the present invention, in the case, the partition surface having substantially the same dimensions in the plan view, the upper spacer piece and the lower portion having the same dimensions by bending the upper surface-bottom surface direction with respect to the partition surface. By reinforcing the strength against the force in the upper surface-bottom direction by the side spacer piece, it is possible to prevent the case from being deformed even if a force is applied from the printer side.

In the present invention, in consideration of environmental pollution at the time of disposal and manufacturing cost, it is made into a shared part as a housing (case) that can correspond to the width type of the printing medium, and all except the label tape which is the content is made of paper. The purpose is to store the label tape with the print medium laminated on one side of the strip-shaped base material in a wrapped state, and to send out the label tape from the inside, the delivery opening, and the shaft body projected on the printer side. A paper case with an insertion opening for inserting in the center of the label tape, and a plan view that divides the height from the top surface to the bottom surface of the case into the upper side and the lower side, which are almost the same dimensions as the inside of the case. An upper spacer piece that has a partition surface and is provided in pairs on the opposite side edges of the partition surface to secure an upper space in the case, and an opposite side adjacent to the upper spacer piece of the partition surface. It is provided with a pair of lower spacer pieces provided at the edges to secure a space under the case, a paper spacer having at least the lower spacer piece, and the spacer is the lower side of the partition surface. This was achieved by locating the label tape in the case and arranging it in the case so that the upper spacer piece can be seen through the delivery opening of the case.

Further, in the above invention, in the above case, in the case, the first side surface to the fourth side surface are continuously formed on the four side edges of the bottom surface, which is opposite to the side continuous with the bottom surface of the first side surface of the four side surfaces. An upper surface is continuously formed at the end portion, and a connection piece attached to the fourth side surface facing the first side surface is attached to the upper surface at the end portion opposite to the side continuous with the first side surface of the upper surface. It is continuously formed, and at both ends of each of the first side surface and the fourth side surface, a reinforcing piece that opposes the force in the upper surface-bottom direction by being folded inward is formed, and also with the first side surface. Box-making of paper pieces, each of which has a reinforcing piece that opposes the force in the top-bottom direction by being folded inward at the end of the adjacent second side surface and the third side surface on the side not continuous with the bottom surface. It may be configured as such.

With the above configuration, there is only one part to be attached when assembling the case (box making), which can be easily created, and the reinforcing pieces formed on the second and fourth side surfaces are partitions. Since it is located on the upper side of the surface, that is, in a space where the label tape does not exist, it does not hinder the rotation of the label tape during transportation. Further, in the above configuration, if the delivery opening is formed on the first side surface, the strength with respect to the force in the upper surface-bottom direction does not decrease as compared with the case where the delivery opening is formed on the second and fourth side surfaces.

Further, in the above invention, if a cut is formed in the insertion opening and the cut is torn to form an opening by pushing the shaft body, it is possible to easily grasp whether the insertion opening is used or not, and the present invention is not yet used. Dust and debris do not directly enter through the insertion opening under the partition surface where the label tape is present during use.

Further, in the above invention, if a confirmation window for confirming the usage status of the label tape is formed at the same position in the plan view near the center of the upper surface of the case and the partition surface of the spacer, the usage status of the label tape can be checked. Can be grasped.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 8. Reference numeral 1 is a paper cartridge used for the label printer 11 shown in FIG. Here, before explaining the configuration of the paper cartridge 1 of the present invention, the label tape P and the label printer 11 will be described below.

The label tape P has a heat-sensitive printing medium Pb laminated on a strip-shaped base material Pa, wrapped around the label tape P, and stored in a case 2 described later of the paper cartridge 1. Although the configuration of the label tape P is not limited in the present invention, the "base material Pa" in this example supports the print medium in order toward the lower layer when the layer of the print medium Pb is the uppermost surface. A "base material layer" for attaching the print medium to the adherend and a "adhesive layer" for detachably attaching the release layer, and for peeling from the adhesive layer to expose the adhesive layer. The laminated body of "release paper" (bottom surface) is generically referred to. This label tape P has a large number of tape widths (6 mm, 9 mm, 12 mm, 18 mm in this embodiment).

The label printer 11 inputs characters and the like, a mounting portion 12 on which the paper cartridge 1 is mounted, a head portion 13 having a heat-sensitive head 13a for printing on the mounting portion 12, and a transport roller 13b for feeding the label tape P. It is provided with an input unit 14 for printing, a display unit 15 for displaying input characters and the like, and a setting unit 16 for various settings.

The label printer 11 in the present embodiment has a configuration particularly related to the paper cartridge 1 of the present invention, and the mounting portion 12 is made of paper from above the mounting recess 12A into which the paper cartridge 1 is inserted and the mounting recess 12A. It is composed of a lid portion 12B that covers the upper surface of the cartridge 1.

In the mounting recess 12A, a shaft body 12Aa for inserting and positioning the label tape P into the winding center hole of the label tape P is provided so as to project upward from substantially the center of the inner bottom surface (direction in which the paper cartridge 1 is mounted). ing. Further, of the four corners of the inner bottom surface of the mounting recess 12A, positioning pins 12Ab, 12Ab, 12Ab for positioning the paper cartridge 1 are projected from the three corners in this embodiment. The head portion 13 is provided in the vicinity of the inner side surface of the mounting recess 12A on the side of the input portion 14 and the display portion 15.

Further, holes 12Ac, 12Ad, 12Ae into which the guide pieces 12Ba, 12Bb and the engaging claws 12Bc of the lid portion 12B, which will be described later, are inserted are formed in the outer edge portion of the side wall of the mounting recess 12A. Further, a hinge 12Af that allows the lid portion 12B to be opened and closed freely is provided at a predetermined outer edge portion of the side wall that is separated from the display portion 15 of the mounting recess 12A.

Further, a window 12Ba for visually confirming the consumption status of the label tape P inside the paper cartridge 1 is formed in the lid portion 12B substantially in the center with the lid portion 12B closed. Guide pieces 12Ba, 12Bb and engaging claws 12Bc are formed on the back surface of the lid portion 12B at positions corresponding to the holes 12Ac, 12Ad, and 12Ae in the mounting recess 12A, respectively.

Further, on the back surface of the lid portion 12B, on the edge portion of the window 12Ba, for example, two fixing pieces 12Bd for pressing and fixing the upper surface of the paper cartridge 1 are formed in this embodiment. That is, the label printer 11 in this embodiment has a configuration in which the entire paper cartridge 1 (configured to be compatible with the label printer 11) is positioned by the mounting portion 12, specifically, the label tape in the paper cartridge 1. The winding center of P is positioned by the shaft body 12Aa, the upper surface is positioned by the fixing piece 12Bd, and the three corners are positioned by the positioning pins 12Ab, 12Ab, 12Ab.

The paper cartridge 1 of the present invention has a portion configured according to the formation position of the positioning pin 12Ab described above of the label printer 11, but basically has the following configuration (universally). .. The paper cartridge 1 is a paper spacer 3 in which a wrapped label tape P and the label tape P are inserted into a paper case 2 to form a space corresponding to the tape width of the label tape P. And, it is equipped with.

Here, in the paper cartridge 1 of the present invention, both the case 2 and the spacer 3 are made of paper, but it is preferable to adopt the ones under the following conditions. It is an essential requirement that the paper constituting the case 2 and the spacer 3 of the paper cartridge 1 of the present invention is flammable. In this embodiment, coated paper having the following thickness was used in consideration of strength and ease of assembly.

The thickness of the paper can be adopted in the range of 230 to 450 g / m ² , with 310 g / m ² being the most suitable, and 270 to 350 g / m ² being the preferred range. If it is thinner than 230 g / m ² , it lacks shape stability after assembly, and may not be able to withstand the pressure of the printer, for example, the fixed piece 12Bd, and may be deformed. On the other hand, if it is thicker than 450 g / m ² , it is difficult to bend it at the time of assembly, and it tends to return to the initial shape due to repulsion, which may result in poor workability and increase in material cost.

However, the above range of 230 to 450 g / m ² of the paper thickness is only an experiment in which the outer shape of the case is about 75 × 75 × 22 mm. For example, when the overall size of the paper cartridge 1 is large, the above range is included. If the overall size of the paper cartridge 1 is small, the thicker one is preferable, and the thinner one is also preferable.

The case 2 is a rectangular parallelepiped, and the external dimensions do not change depending on the label tape P having a tape width of 6 mm, 9 mm, 12 mm, or 18 mm. The paper cartridge 1 of the present invention is characterized in that the outer diameter of the case 2 is unchanged, and the variation in the tape width is dealt with by the spacer 3 described later.

As shown in FIGS. 1 to 4, the case 2 is formed by bending the first side surface 2S1, the second side surface 2S2, the third side surface 2S3, and the fourth side surface 2S4 from each of the four sides of the bottom surface 2B. The first side surface 2S1 is continuously provided with a top surface 2T at the opposite end connected to the bottom surface 2B. The second side surface 2S2 and the third side surface 2S3 are adjacent to the first side surface 2S1 on both sides, and the fourth side surface 2S4 is located so as to face the first side surface 2S1.

At both ends of the first side surface 2S1 and the fourth side surface 2S4 in the direction of the second side surface 2S2 and the third side surface 2S3, as a reinforcing material that resists the force in the upper surface-bottom direction by being folded when the case 2 is assembled. The functional reinforcing pieces 2S1a and 2S1a and the reinforcing pieces 2S4a and 2S4a are formed, respectively.

Further, at the end portions of the second side surface 2S2 and the third side surface 2S3 in the upper surface direction, the case 2 is folded when the case 2 is assembled to maintain the three-dimensional shape and as a reinforcing material that resists the force in the upper surface-bottom direction. A functional reinforcing piece 2S2a and a functional reinforcing piece 2S3a are each formed. By folding the reinforcing piece 2Sa and the reinforcing piece 2S3a toward the upper surface 2T side, the reinforcing piece 2Sa and the reinforcing piece 2S3a do not interfere with the rotational operation of the label tape P located below the partition surface 3A, which will be described later.

Further, at the end of the upper surface 2T opposite to the first side surface 2S1, a connection piece 2Ta that is folded inward and is connected to the back surface (inside) of the fourth side surface 2S4 by, for example, adhesion is formed. ing. By doing so, there is only one adhesive portion for assembling the case 2, and the rest is only required to be bent or folded, which is excellent in workability. Further, in particular, by connecting the connection piece 2Ta to the back surface (inside) of the fourth side surface 2S4 by adhesion as in this example, the case 2 can be stably maintained in shape.

The case 2 is bent so that the first side surface 2S1 to the fourth side surface 2S4 stand upright at right angles to the bottom surface 2B, and the reinforcing pieces 2S1a and 2S1a of the first side surface 2S1 are the reinforcing pieces 2S4a and 2S4a of the fourth side surface 2S4, respectively. Each of them is bent toward the inside of the case 2 so as to abut against each other, and the reinforcing pieces 2S2a of the second side surface 2S2 and the reinforcing pieces 2S3a of the third side surface 2S3 are perpendicular to the second side surface 2S2 and the third side surface 2S3, respectively. Bend it into a shape and bend it toward the inside of the case 2.

Further, in the case 2, the upper surface 2T is bent so as to face the bottom surface 2B at a right angle to the first side surface 2S1, and the connection piece 2Ta of the upper surface 2T is bent so as to be located inside the fourth side surface 2S4. 2Ta and the fourth side surface 2S4 are adhered to each other. The spacer 3 loaded with the label tape P is inserted through an opening formed before bending the second side surface 2S2 and the reinforcing piece 2S2a or the third side surface 2S3 and the reinforcing piece 2S3a in the case 2.

Further, in the case 2, a delivery opening 2a for sending the label tape P out of the case 2 is formed on the first side surface 2S1. By forming the delivery opening 2a on the first side surface continuous with the bottom surface 2B and the top surface 2T in this way, it is possible to suppress a decrease in strength due to the formation of the delivery opening 2a.

Further, a window 2b for confirming whether the shaft body 12Aa of the label printer 11 penetrates the winding center of the label tape P at the center position of the upper surface 2T, and a winding end surface of the label tape P near the window 2b. A confirmation window 2c for peeping and confirming the consumption status is formed. Further, in the present embodiment of the bottom surface 2B, insertion holes 2e, 2e, 2e into which the positioning pins 12Ab, 12Ab, 12Ab of the label printer 11 are inserted are formed at the three corners, respectively.

Further, in the case 2, an insertion opening 2d into which the shaft body 12Aa of the label printer 11 is inserted is formed at the center position of the bottom surface 2B. The insertion opening 2d is formed so that the insertion opening is formed once it is used, and the winding core having a reduced remaining amount is inserted into the winding center of the label tape P by restricting the portion protruding inside the insertion opening. It is composed. In this embodiment, the insertion opening 2d has a cut 2da formed therein, and is kept closed until the shaft body 12Aa is inserted. By inserting the shaft body 12Aa, the cut 2da is cracked and the insertion opening 2d is inserted. Is formed, and the shaft body 12Aa is configured to be inserted into the case (the winding center of the label tape P).

By forming the cut 2da in the insertion opening 2d in this way, the unused paper cartridge 1 can be grasped by the fact that the insertion opening 2d is not open. Further, in the unused paper cartridge 1, it is possible to prevent dust and dirt from directly entering the lower side of the partition surface 3A to be described later where the label tape P is located.

As shown in FIGS. 5 to 8, the spacer 3 is configured according to the tape widths of 6 mm (FIG. 5), 9 mm (FIG. 6), 12 mm (FIG. 7), and 18 mm (FIG. 8) of the label tape P. However, it is configured to be stored in the case 2 having a constant external dimension without rattling.

The spacers 3 are formed in pairs (folded downward) from the partition surface 3A and the edges of the four sides of the partition surface 3A so as to face outward from the center of the partition surface 3A toward the outside. ) Spacer pieces 3SD, 3SD, and spacer pieces 3SU, 3SU (which can be bent upward). The spacer piece 3SD and the spacer piece 3SD, and the spacer piece 3SU and the spacer piece 3SU function as a reinforcing material that withstands the pressing force in the upper surface-bottom direction and the force in the twisting direction in the case 2 of the paper cartridge 1.

In this example, the spacer 3 corresponding to the tape widths of 6, 9, and 12 mm shown in FIGS. 5 to 7 has a difference from the internal height (constant) of the case 2, and the spacer 3 rattles up and down. Although the spacer pieces 3SU and 3SU that are bent upward so as not to be attached are formed, the spacer pieces 3SU and 3SU are not formed on the spacer 3 corresponding to the tape width of 18 mm shown in FIG. When the spacer piece 3 (with a width of 18 mm) shown in FIG. 8 has a large difference from the internal height of the case 2, the spacer pieces 3SU and 3SU are formed.

The spacer pieces 3SD and 3SD are bent downward with respect to the partition surface 3A, and the bending height is set to be slightly larger than the tape width of the label tape P. Then, when the spacer pieces 3SD and 3SD are inserted into the case 2, their surfaces come into contact with each other inside the second side surfaces 2S2 and 2S3. In addition, in FIGS. 5 to 8, in order to indicate the tape width “type”, the bending height of the spacer pieces 3SD and 3SD indicates the tape width. The bending height of 3SD is about 7 mm.

The spacer pieces 3SU, 3SU are bent upward with respect to the partition surface 3A, and the bending height is from the height of the first side surfaces 2S1 to 2S4 in the case 2, the heights of the spacer pieces 3SD, 3SD and the partition surface 3A. It is said that the height is reduced from the paper thickness. Then, when the spacer pieces 3SU and 3SU are inserted into the case 2, their surfaces come into contact with each other inside the first side surfaces 2S1 and 2S4.

One of the spacer pieces 3SU and 3SU comes into contact with the inside of the first side surface 2S1 in which the delivery opening 2a is formed when inserted into the case 2, but is bent upward with respect to the partition surface 3A. That is, the delivery opening 2a is not blocked in the downward direction of the partition surface 3A in which the label tape P is stored.

In short, in FIG. 5, the height of the spacer pieces 3SD, 3SD and the heights of the spacer pieces 3SD, 3SD (including the paper thickness of the partition surface 3A) are equal to the height inside the case 2, and the tape width is small. As shown, when the heights of the spacer pieces 3SD and 3SD are small, the spacer pieces 3SU and 3SU are present, and the height is large and the tape width is large, only the spacer pieces 3SD and 3SD are formed as shown in FIG. , Spacer pieces 3SU, 3SU do not exist. For example, FIG. 5 shows a spacer 3 having a tape width of 6 mm, FIG. 6 shows a tape width of 9 mm, FIG. 7 shows a tape width of 12 mm, and FIG. 8 shows a spacer 3 having a tape width of 18 mm.

Further, on the partition surface 3A, the insertion hole 3a of the shaft body 12Aa corresponding to the window 2b and the insertion opening 2d of the case 2 and the confirmation window 3b corresponding to the confirmation window 2c of the case 2 in the vicinity of the insertion hole 3a are provided. Is formed. By doing so, the usage status of the label tape P located below the partition surface 3A and the insertion status of the shaft body 12Aa can be confirmed from the outside of the case 2 (from the window 12Ba in the label printer 11).

As described above, since the paper cartridge 1 of the present invention is made entirely of paper except for the label tape P, it is flammable and therefore easy to dispose of and easy to assemble. Further, even if the paper cartridge 1 is made of paper, the upper surface-bottom surface is provided by providing the spacer pieces (3SD, 3SU) in the spacer 3 and by providing the reinforcing pieces (2S1a to 2S4a) of the case 2. Deformation and distortion due to the force received from the direction are suppressed.
