Description

  The present invention relates to a printer.

  The printer has a glue surface on one side and a linerless roll paper with the glue side wrapped around the core in a roll shape. There is one that allows predetermined printing on the non-side surface.

  The roll paper used in such a printer tends to be sticky on both sides with respect to the roll paper feeding direction in a state of being wound around the core.

  Therefore, when such roll paper is directly stored in the roll paper storage portion of the printer and both side surfaces of the roll paper are regulated by side regulating members such as a paper guide in order to regulate the position in the width direction. The frictional resistance acting between the respective side surface regulating members and both side surfaces of the roll paper becomes very large due to the glue on the roll paper side.

  As a result, even if the roll paper is fed out by the conveyance system during printing, the paper cannot be fed due to the frictional resistance, and even if the paper can be fed, the paper can be stably fed at a normal paper feed speed. It is easy to get lost.

  Therefore, in the conventional roll paper storage unit, for example, as shown in FIG. 6, one end of a core mounting shaft 32 having a step portion 32 a is fixed to one side plate 31 of the roll paper storage unit, and the core mounting shaft 32 is rolled. The core 33 of the paper 30 is inserted and held so as to be rotatable.

  In a state where the roll paper 30 is inserted into the core mounting shaft 32, the portion of the core 33 is in contact with the stepped portion 32 a of the core mounting shaft 32 so that the side surface 30 a of the roll paper 30 does not contact the inner surface of the side plate 31. By doing so, an increase in frictional force due to the adhesive adhered to the inner surface of the roll paper 30 adhering to the side plate 31 is prevented.

  An annular convex portion 36 is also formed around the core attachment shaft insertion hole 35 on the other side plate 34 so that the side surface 30 b of the roll paper 30 does not contact the side plate 34.

  However, as the roll outer diameter of the roll paper becomes smaller, the feeding side rolls up, and the glue surface of the roll paper may come into contact with the inner surface of the storage unit cover. Further, there is a problem that frictional resistance is generated between the peripheral surface of the roll paper and the bottom surface of the storage unit.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to enable more smooth roll paper feeding.

  In order to solve the above-described problems and achieve the object, a printer according to the present invention includes a storage unit that stores roll paper that is glued on the inner surface side and is fed from the end of winding, and the storage unit. A storage section cover that can be opened and closed, and a plurality of ribs are formed on the inner surface of the storage section cover that faces the glue surface of the roll paper when the roll paper is conveyed. Features.

  According to another aspect of the present invention, there is provided a printer including: a storage unit that stores and stores a roll paper having an adhesive surface on the inner surface side; and a plurality of ribs formed on the bottom surface.

  According to the present invention, even if the roll paper roll-out side rolls up due to the roll outer diameter of the roll paper being reduced, the roll paper has a glue surface that is difficult to stick to the inner surface of the storage unit cover. Can be prevented from being fed out, and roll paper can be fed out more smoothly.

  Further, according to the present invention, the roll paper can be fed more smoothly by reducing the frictional resistance between the peripheral surface of the roll paper and the bottom surface of the storage unit.

FIG. 2 is a schematic configuration diagram showing only main parts of the portable printer having the roll paper storage unit. FIG. 3 is a schematic view showing a state in which the bearing portion of the platen is engaged with the swing plate in the process of closing the storage unit cover of the portable printer. FIG. 4 is a schematic diagram showing a state in which when the roll diameter of the roll paper is reduced, the feeding side is rolled up and the glue surface comes into contact with the inner surface of the storage unit cover. FIG. 5 is a longitudinal sectional view similar to FIG. 1 showing an embodiment in which both sides of the roll paper can be regulated by a movable roll paper guide plate. FIG. 6 is a front view partially showing a cross section of an example of a roll paper storage unit for setting roll paper using a conventional core mounting shaft.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a longitudinal sectional view showing a roll paper storage portion of the printer according to the present invention together with the roll paper, and FIG. 2 is a schematic configuration diagram showing only main parts of the portable printer having the roll paper storage portion.

  The portable printer shown in FIG. 2 is a small portable printer, and the roll paper 10 stored as shown in the storage position of the roll paper storage unit 2 provided in the frame 1 is indicated by an arrow A from the winding end side. The roller-shaped platen 3 that rotates in the direction is fed in the direction indicated by the arrow B.

  The platen 3 is in pressure contact with the thermal head 4 via the roll paper 10 during printing, and the roll paper 10 performs desired printing by the thermal head 4.

  The roll paper 10 used in the portable printer is, for example, a roll-shaped paper in which a label piece 12 is preliminarily pasted with glue at a predetermined interval in the roll paper feeding direction on a base paper (liner) 11 and wound around a core 13. It is a thing.

  Then, the roll portion of the roll paper 10 is set in the roll paper storage section 2 of the frame 1, and the winding end side is pulled out as shown in FIG. 2, while being pressed against the platen 3 and the platen 3. The part of the mount 11 is sent out in the direction of arrow C by the peel roller 5 rotating in the direction of the arrow.

  A peeling member 6 is provided on the downstream side of the platen 3 in the roll paper conveyance direction so as to be close to the platen 3. Therefore, after the desired printing is performed on the label piece 12 of the roll paper 10, the roll paper 10 sent out in the direction indicated by the arrow B has the label piece 12 itself as a result of the conveying direction being changed abruptly by the peeling member 6. It peels from the mount 11 due to the strength of the waist, and is separated from the mount 11 and discharged in the direction of arrow E.

  The platen 3 is rotatably supported at one end of the storage unit cover 7, and the storage unit cover 7 is placed above the storage position of the roll paper storage unit 2 and above the roll paper 10 set at the storage position. The right end portion in FIG. 2 is attached to the frame 1 so that it can be opened and closed by a shaft 8 so as to cover it.

  A gear (not shown) is fixed to one end of the shaft portion that supports the platen 3, and when the storage cover 7 is closed as shown in FIG. 2, the gear is provided on the frame 1 side. It meshes with a drive gear (not shown) so that it can rotate.

  Further, the peel roller 5 is rotatably attached to a swing plate 14 rotatably attached to the frame 1 by a shaft 9, and the swing plate 14 is counteracted in FIG. Although it is urged to rotate clockwise, as shown in FIG. 3, in the process of closing the housing cover 7, the bearing portion 3 a that supports the shaft portion of the platen 3 is laterally U-shaped on the swing plate 14. 2 is brought into contact with the engaging portion 14a formed at the bottom and pushed down, the position shown in FIG.

  On the contrary, when the storage portion cover 7 is opened, the bearing portion of the platen 3 is disengaged from the engaging portion 14a of the swing plate 14, so that the swing plate 14 is rotated counterclockwise in FIG. 2 by the biasing force of the spring. Then, the peel roller 5 is retracted to a position where it does not interfere with the platen 3.

  Thus, in this portable printer, the swinging plate 14 holding the peel roller 5 rotates in conjunction with the opening / closing operation of the storage section cover 7.

  As described with reference to FIG. 2, the roll paper storage unit 2 stores, for example, the roll paper 10 in which a large number of label pieces 12 are adhered to each other with glue at predetermined intervals along the feeding direction.

  Then, with the roll paper 10 stored in the storage position of the roll paper storage unit 2, the roll paper 10 is misaligned in the width direction (front and back in FIG. 2) and shifted in the width direction to the print position. Therefore, it is necessary to regulate the positions of both side surfaces with respect to the feeding direction of the roll paper 10 with the side surface regulating members.

  In view of this, in this portable printer, as the side surface regulating member, the side surface on one conveyance reference side of the roll paper 10 is directly regulated by the inner surface 1a of the frame 1 as shown in FIG. Further, the other side surface of the roll paper 10 is regulated by a roll paper guide plate 15 that functions as a side surface regulating member.

  The roll paper guide plate 15 is a sheet metal guide plate that can be inserted into and removed from the frame 1. The roll paper 10 is placed on the storage unit bottom surface 2 a on which the roll paper is placed at the storage position of the roll paper storage unit 2 of the frame 1. By inserting a lower end into each of the guide plate insertion grooves 16 formed at intervals in the width direction, it is possible to move to a position suitable for the width of the roll paper 10.

  The surface (inner surface) that regulates the side surface of the roll paper 10 of the roll paper guide plate 15 is subjected to non-adhesive treatment. In this embodiment, the non-adhesive treatment is applied by applying the anti-sticking paint 20. Is going.

  For example, the trade name Bicoat (Yoshida SKT), the trade name Papyres (Natoco Paint Co., Ltd.), the trade name Deflick (Kawabe Laboratories), etc. are used as the anti-sticking paint.

  Further, similarly to the non-adhesive treatment, similarly to the non-adhesive treatment, the inner surface 1a of the frame 1 that regulates the other side surface of the roll paper 10 is pasted with a seal member 17 that is coated with a paste-preventing paint 20 on one side and glued on the back side. In addition, the surface to which the paper sticking prevention paint 20 is applied is brought into contact with the side surface of the roll paper 10.

  As described above, the roll paper storage unit of the printer performs the non-adhesion process on the inner surface 1a of the frame 1 that regulates the positions of both side surfaces of the roll paper 10 and the inner surface of the roll paper guide plate 15, respectively. In the case where the piece 12 is located up to both ends in the width direction of the mount 11, the glue attached to the label piece 12 is attached to both side surfaces of the roll paper 10, and the glue becomes a sliding resistance and rolls. Although it is easy to prevent the paper from being fed out, the frictional resistance can be reduced by the non-adhesive treatment, so that the roll paper can be smoothly fed out.

  The roll paper 10 can be set in the roll paper storage unit 2 simply by placing the roll paper 10 on the storage unit bottom surface 2 a of the roll paper storage unit 2. Therefore, unlike the conventional roll paper storage unit, it is not necessary to insert the roll paper core into the core mounting shaft provided on the printer side, so the roll paper can be easily set to the storage position accordingly. be able to.

  Further, since the core is not used for setting the roll paper, even if the outer diameter of the entire roll paper is the same, a larger amount of roll paper can be stored as much as the diameter of the core can be reduced.

  Further, as shown in FIG. 1, the roll paper storage unit of the printer is provided with a plurality of ribs 19 along the feeding direction of the roll paper 10 on the storage unit bottom surface 2 a of the frame 1. Therefore, the frictional resistance between the peripheral surface of the roll paper 10 and the storage unit bottom surface 2a of the frame 1 is reduced, and the roll paper 10 can be fed out more smoothly.

  By the way, the roll paper storage unit 2 is not configured to insert the core 13 provided at the center of the roll paper 10 into the core mounting shaft on the printer side and set the roll paper 10 as described above. As the roll is used, the outer diameter of the roll gradually decreases, so that a large empty space can be formed above the roll paper storage unit 2.

  Therefore, as shown in FIG. 4, when the roll paper 10 'to be used has a glue surface 10a on the entire inner surface side, the roll paper 10' has a smaller roll outer diameter. Since there is a space that allows dancing in the direction indicated by the arrow G, the feeding side may be rolled up as shown in the figure, and the glue surface 10a may be in contact with and adhered to the inner surface of the storage portion cover 7.

  However, the roll paper storage unit 2 is provided with a plurality of ribs 18 along the feeding direction of the roll paper 10 on the inner surface of the storage unit cover 7 as shown in FIG. Even if the feeding side of the roll paper 10 'is rolled up, the roll paper 10' prevents the roll paper 10 'from being unable to be fed because the adhesive surface 10a is difficult to stick to the inner surface of the storage cover 7. be able to.

  FIG. 5 is a longitudinal sectional view similar to FIG. 1 showing an embodiment in which the left and right side surfaces of the roll paper can be regulated by a movable roll paper guide plate.

  The roll paper storage unit of the printer according to this embodiment is a sheet metal roll paper guide that allows the left and right sides of the roll paper 10 to be inserted into and removed from the frame 1 with respect to the embodiment described with reference to FIGS. The plates 15 and 25 are regulated, and an anti-sticking paint 20 is applied to the inner surfaces thereof.

  According to this roll paper storage unit, if the left and right roll paper guide plates 15 and 25 are inserted and set in the guide plate insertion grooves 16 and 16 at left and right symmetrical positions as shown in the drawing, the roll paper 10 is set to the center reference. Can guide.

  In each of the above-described embodiments, when the anti-sticking coating 20 is used as a non-adhesive treatment for preventing the friction resistance between the roll paper side surface and the side surface regulating member from being increased due to the influence of the glue on the roll paper side surface. As an example of the non-adhesive treatment, the inner surface 1a of the frame 1 that restricts one side surface of the roll paper 10 may be subjected to a texture treatment by resin molding, for example.

  In that case, the other side surface of the roll paper 10 may be directly regulated by the inner surface of the other frame 1, and the inner surface 1a may be subjected to a texture treatment by resin molding. If it does so, since non-adhesion processing can be performed only by resin molding, manufacture becomes easy.

  Further, a roll paper guide plate made of resin that can be inserted into and removed from the frame 1 (the shape is similar to that of the roll paper guide plates 15 and 25) is provided, and the surface of the roll paper guide plate that regulates the roll paper 10 is formed as a mold. An embossing process may be performed by molding.

  Further, the storage unit bottom surface 2a on which the roll paper 10 at the storage position of the frame 1 shown in FIG. 1 is placed is subjected to a texture treatment (for example, a resin material is formed by molding) together with a plurality of ribs 19 provided there. May be. By doing so, the frictional resistance between the roll paper 10 and the storage portion bottom surface 2a can be further reduced, so that the roll paper 10 can be fed out more smoothly.
