[0001]
BACKGROUND OF THE INVENTION
The present invention particularly relates to a label issuing device that prints on a label using a thermal head.
[0002]
[Prior art]
As a conventional label issuing device, for example, one disclosed in Japanese Patent Laid-Open No. 2001-106216 and disclosed in FIG. 3 is known.
[0003]
In this label issuing device, the recording paper 1 wound around the core material S is used. A roll-like recording paper 1 temporarily attached with a label 1b at a predetermined interval to the belt-like mount 1a is stored in a recording paper storage portion 2a provided in the main body 2, and the recording paper 1 is loaded from the recording paper storage portion 2a. It is configured to be pulled out and sent to the label issuing unit 2b as a discharge port.
[0004]
A platen roller 5 is attached to the lid 3 of the main body 2, and comes into contact with the print head 4 in a state where the lid 3 is positioned at the closed position (state shown in FIG. 3).
[0005]
In addition, a peeling member 9 is provided in the vicinity of the discharge side of the platen roller 5 in parallel with the platen roller 5 at a distance, and at a position facing the peeling member 9 with the recording paper 1 interposed therebetween. A roller-shaped label issuance switching member 10 is provided on the surface of the main body 2 so as to bend the belt-like mount 1a by pressing the belt-like mount 1a of the recording paper 1 against the peeling member 9. The label issuance switching member 10 is rotatably supported by a movable body 11 that is slidably mounted along a direction intersecting the length direction of the platen roller 5 (the direction of arrow F in FIG. 3).
[0006]
As the movable body 11 slides, the label issuance switching member 10 is printed from the label issuance portion 2b when the label issuance switching member 10 is located above the contact position between the print head 4 and the platen roller 5. The labels 1b are sequentially discharged together with the belt-like mount 1a, and the labels 1b are continuously issued.
[0007]
On the other hand, when the label 1b is peeled and issued, the movable body 11 is moved downward to move the label issuance switching member 10 to the position indicated by the two-dot chain line, and the label issuance switching member 10 is moved beyond the peeling member 9. Is brought into contact with the platen roller 5 and positioned.
In the process of moving the movable body 11 to such a position, the belt-like mount 1a is pressed against the peeling member 9 by the label issuance switching member 10, and is folded back toward the platen roller 5 at the contact portion with the peeling member 9. In addition, in a state where the platen roller 5 and the label issuance switching member 10 are sandwiched, the through hole 12 formed in the movable body 11 is in contact with the print head 4 and the platen roller 5. It is made to oppose in the part vicinity. Then, the belt-like mount 1a is conveyed from the contact portion between the print head 4 and the platen roller 5 through the peeling member 9 to the outside of the main body 2 from the contact portion between the label issuance switching member 10 and the platen roller 5. Is formed, and the conveying path exhibits a state of being largely bent, which is referred to as turning in the peeling member 9. The turning label 1b of the strip 1a in the peeling member 9 is peeled off from the strip 1a by its own rigidity so that the label 1b can be issued alone.
In addition, 14 in FIG. 3 shows the clip in the case of attaching to an operator etc.
[0008]
However, in such a conventional label issuing device, the peeling member 9 is required when the peeling is issued. Especially in a portable printer that is required to be light and compact, not only the peeling member 9 but also the peeling member 9 is required. Therefore, it has been desired to develop an apparatus that can reduce the number of peeling members and also has good peelability of the label 1b from the belt-like mount 1a.
[0009]
[Problems to be solved by the invention]
The present invention has been made paying attention to the problems as described above, and provides a label issuing device that improves the peelability of the label from the strip mount after reducing the peeling member 9. Let it be an issue.

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 and 2.
In addition, about the part similar to the past, only the same code | symbol is attached | subjected and duplication description is abbreviate | omitted.
[0012]
FIG.1 and FIG.2 has shown the enlarged side view of the label issuing part 2b vicinity as a discharge port, respectively.
In the label issuing apparatus according to the present embodiment, a guide plate 20 for guiding the recording paper 1 is disposed on the upstream side of the print head 4.
The guide plate 20 is provided so as to be close to or away from the platen roller 5 by using fine adjustment means such as screws (not shown), and a recording paper is provided between the guide plate 20 and the platen roller 5. The recording paper 1 fed out from the storage portion 2a passes therethrough. When passing, the recording paper 1 is guided by the guide plate 20 and conveyed to the print head 4.
[0013]
Since the guide plate 20 for guiding the recording paper 1 can be moved closer to and away from the platen roller 5 by means of fine adjustment means (not shown), the platen roller 5 and the recording paper 1 on the upstream side of the print head 4 The contact area changes. That is, when the guide plate 20 approaches the platen roller 5, the recording paper 1 is pressed toward the platen roller 5, increasing the contact area with the platen roller 5, while the guide plate 20 is separated from the platen roller 5. As a result, the contact area between the platen roller 5 and the recording paper 1 decreases. The contact area between the platen roller 5 and the recording paper 1 is hereinafter referred to as “circumferential contact area” because the recording paper 1 is in contact with the circumferential surface of the platen roller 5, that is, in circumferential contact.
[0014]
The recording paper 1 guided by the guide plate 20 is sandwiched between the print head 4 and the platen roller 5 and is issued from the label issuing unit 2b.
[0015]
In the vicinity of the label issuing portion 2 b of the main body 2, a movable body 11 provided with a through hole 12 and a roll-shaped label issuance switching member 10 is provided slidably with respect to the main body 2.
[0016]
FIG. 1 shows a state in which the label issuance switching member 10 is positioned above the contact position between the print head 4 and the platen roller 5 and the recording paper 1 as the movable body 11 slides. At this time, the printed label 1b is sequentially discharged together with the belt-like mount 1a from the label issuing unit 2b, and the label 1b is continuously issued.
On the other hand, when the label 1b is peeled and issued, the movable body 11 is slid downward and the label issuing switching member 10 is moved beyond the apex position of the platen roller 5 as shown in FIG. 5 to be positioned. At this time, the through hole 12 formed in the movable body 11 is positioned so as to face the label issuing portion 2b.
[0018]
Here, the positional relationship among the label issue switching member 10, the platen roller 5, the print head 4, and the guide plate 20 at the time of release is described in detail.
As shown in FIG. 2, the platen roller 5 rotates about the rotation center O.
When the vertical line passing through the rotation center O of the platen roller 5 is V, and the horizontal line perpendicular to the vertical line V is H, the print head 4 and the platen roller 5 are substantially at the apex of the upper part where the vertical line V intersects the outer peripheral surface of the platen roller 5. The contact is made in the vicinity of the position V1.
On the other hand, the label issuance switching member 10 abuts on the downstream side from the vertex position H1 on the left end side where the horizontal line H intersects the outer peripheral surface of the platen roller 5.
Further, as described above, the guide plate 20 is disposed so as to be able to approach and separate from the platen roller 5. When the guide plate 20 is brought close to the platen roller 5, the recording guided by the guide plate 20 is performed. The paper 1 comes closer to the rightmost apex position H2 where the horizontal line H intersects with the outer peripheral surface of the platen roller 5 to increase the peripheral contact area between the platen roller 5 and the recording paper 1 and, conversely, When the guide plate 20 is separated from the platen roller 5, the recording paper 1 comes closer to and comes into contact with the vertex position V 1 of the vertical line V of the platen roller 5 so that the circumferential contact area between the platen roller 5 and the recording paper 1 is reduced. It has become.
[0019]
Next, the usage state of the label issuing device will be described.
[0020]
When the label 1b is continuously issued, the movable body 11 is slid to the upper part of the main body 2 as shown in FIG. Along with the sliding, the movable body 11 opens the label issuing portion 2b of the main body 2, and the label issuing switching member 10 is positioned above the contact position between the print head 4 and the platen roller 5.
[0021]
In this state, the recording paper 1 is pulled out from the recording paper storage unit 2a, passed between the guide plate 20 and the platen roller 5, and further sandwiched between the print head 4 and the platen roller 5 to the label issuing unit 2b. When the label issuing device is operated by turning on a switch (not shown), the recording paper 1 sandwiched between the print head 4 and the platen roller 5 temporarily attaches the label 1b to the belt-like mount 1a as the platen roller 5 rotates. It is continuously issued from the label issuing unit 2b in a state.
[0022]
Next, when the label 1a is peeled and issued, the recording paper 1 is pulled out from the recording paper storage unit 2a, passed between the guide plate 20 and the platen roller 5, and sandwiched between the print head 4 and the platen roller 5. The label is issued to the label issuing unit 2b, and the belt-like mount 1a is placed in a standby state at the lower part in a state where the belt-like mount 1a is in contact with the platen roller 5.
At this time, the guide plate 20 is positioned at a position closest to the platen roller 5 by a fine adjustment means (not shown) such as a screw, and is adjusted so that the circumferential contact area between the platen roller 5 and the recording paper 1 is maximized. To do.
And as shown in FIG. 2, the movable body 11 is slid to a downward part. As the movable body 11 slides, the label issuance switching member 10 is positioned downstream from the apex position H1 (left end side) of the horizontal line H of the platen roller 5, and the label issuance switching member 10 moves the belt-like mount 1a. The belt-like mount 1a is positioned so as to be pressed against the platen roller 5, and is folded back in a direction away from the label issuing unit 2b in contact with the platen roller 5.
Further, as the movable body 11 slides, the through hole 12 formed in the movable body 11 is positioned to face the label issuing portion 2b.
[0023]
In this state, when a switch (not shown) is turned on to operate the label issuing device, the belt-like mount 1a is sandwiched between the print head 4 and the platen roller 5 while being guided by the guide plate 20, and changes its direction in the vicinity of the through hole 12. Then, a conveying path is formed in which the platen roller 5 is rapidly rounded and turned away from the label issuing unit 2b, and is further sandwiched and pulled between the bell issuing switching member 10 and the platen roller 5.
[0024]
The conveyance path includes an increase in the circumferential contact area accompanying the approach of the guide plate 20 to the platen roller 5 on the input side of the print head 4, and the label issuance switching member 10 on the left end side of the horizontal line H on the downstream side. It is positioned downstream from the apex position H1 and contacts the platen roller 5, and is formed in an arc shape that reaches the half circumference of the platen roller 5, so that the circumferential contact area is large, and the platen roller 5 is sharply rounded. Since the belt-like mount 1a turned around the through-hole 12 is further sandwiched and pulled between the label issue switching member 10 and the platen roller 5, the label 1b temporarily attached to the belt-like mount 1a is easily peeled off. , It will be issued from the through hole 12.
[0025]
In addition, the applicant obtained in practice that the platen roller 5 has a smaller diameter than the conventional one and a diameter of about 10 mm, the turning property is good, and the peelability of the label 1b from the belt-like mount 1a is good. Yes.
[0026]
Note that the approach and separation of the guide plate 20 with respect to the platen roller 5 is such that the upper end portion 20a side of the guide plate 20 is lower than the horizontal line H passing through the rotation center O of the platen roller 5 and the rear end portion of the lower end portion 20b. If the upper end 20a side is swung with the side as a fulcrum, it can be implemented more efficiently, and a larger area of contact between the platen roller 5 and the recording paper 1 can be obtained.
[0027]
【The invention's effect】
The label issuing device according to the present invention guides the recording paper so as to make a circular contact with the platen roller by the guide plate on the upstream side of the print head, and the belt mount on the downstream side of the print head. Is provided with a pressure roller that presses against the platen and bends away from the discharge port, so that the recording paper contacts the platen roller on the input side of the print head, the print head, and the pressure roller and the platen roller. Since the belt-like mount is turned in a long range of position, and the platen roller is rounded, there is an effect that the peelability of the label from the belt-like mount is good even without a peeling means.
