Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a label paper cutting device for a printer that uses a long label paper.

Conventional technology Conventionally, in this type of printer, when necessary information is printed on a label attached to a long backing paper and sent out, a cutter blade is used on the output side of the printer to cut the label paper. fixedly installed,
This cutter blade is used to cut the label paper.

Problems that the invention aims to solve Cutting label paper with a fixed cutter blade installed at the output position of the printer is difficult to do with one hand;
As stated in the back of the issue, there are models in which one end of the fixed blade and one end of the movable blade are biased with elastic bodies so that they can move in the paper feeding direction, but with this type, the cutting position cannot be changed. However, it is difficult to obtain a clean cut edge in a straight line.

Means for Solving the Problem A linear cutting blade is provided on one side of the paper path of the label paper, in which a large number of labels are pasted on a long mount, and both ends of the cutting blade are connected to first and second support shafts. A cutting blade supported movably in the feeding direction of the label paper is provided, and a rotary blade having a blade portion is rotatably supported on the first support shaft, and the cutting blade is rotatably supported on the first support shaft. By providing elastic bodies on both ends of the cutting blade to bias the cutting blade in the direction, as the rotating blade rotates, the blade portion of the rotating blade is moved from the first spindle side to the cutting edge of the cutting blade. They are elastically joined in a point-contact manner toward the second support shaft.

Function: Even if the label paper is not specially pressed, the cutting point remains at one point, and as the rotating blade rotates, the cutting point moves on the cutting blade of the cutting blade, resulting in smooth cutting. Since both ends of the cutting blade are resiliently biased by an elastic body, the sharpness is the same at any position of the cutting blade, and since the position of the rotating blade is fixed, it is easy to cut labels. The position is stable in a straight line and a clean cut edge can be obtained.

Embodiment First, a main body case 1 is provided, and a keyboard 3 on which a large number of operation keys 2 are arranged and a display section 4 are provided on the entire surface of the main body case 1. On the upper surface of the main body case 1, there is provided a supply shaft 6 that holds and supplies the label paper 5 wound into a roll, a winding shaft 8 that winds up the mount 7 of the label paper 5, and the mount 7. A printer 10 as a printing unit that prints necessary information on the attached label 9, and a cutting unit 1 provided near the printer 10.
1 and more.

The printer 10 has a thermal head 12 and a roller 13 which also serves as a platen and faces the thermal head 12.

The cutting unit 11 also has a support 15 erected on a base 14 fixed to the main body case 1.
It is rotatably mounted on the

First, a hinge portion 18 having a shaft hole 17 that fits into the support column 15 is formed on the substrate 16.
A punch hole 20 for forming a paper path 19 is formed in the substrate 16, and a guide plate 22 having a guide surface 21 is attached to the punch hole 20 from the outside. Further, an upper support shaft 23 serving as a first support shaft and a lower support shaft 24 serving as a second support shaft are attached to the inner surface of the substrate 16. Compression springs 25 and 26, each serving as an elastic body, are attached, and a cutting blade 27 is attached to the outside thereof so as to be movable in the axial direction. One side edge of this cutting blade 27 is a straight cutting blade 2
It is said to be 8. Furthermore, a shaft hole 30 formed at a bent portion of a rotary blade 29 formed in an L-shape is rotatably fitted into the upper support shaft 23, and a tension spring 3
1 is biased in one direction. This rotating blade 2
9 has a linear blade portion 3 that contacts the cutting blade 28.
2 is formed. Further, a protrusion 33 on which a finger can be hung is formed at the other end of the rotary blade 29. This rotating blade 29 is fixedly attached so as not to move with respect to the traveling direction of the label 9.

Next, a cover 34 attached to the back surface of the substrate 16 is provided, and the cover 34 has a hinge portion 36 having a shaft hole 35 that fits into the support column 15.
is formed. This cover 34 has a straight edge 3
7 is formed. Further, the substrate 16 is provided with a paper path 19 along with a straight edge 37 of the cover 34.
A guide plate 38 is formed. A guide piece 39 for guiding the label paper 5 is bent on the guide plate 38, and a projecting piece 41 for rotatably holding a locking button 40 is formed on the lower outside. Furthermore, the base 14
A protrusion 42 is formed on the protrusion 42 to be joined to the protrusion 41, and an engagement hole 43 through which the locking button 40 is engaged and disengaged is formed in the protrusion 42.

In such a configuration, the label paper 5 enters the printer 10 from the supply shaft 6 and passes through the cutting unit 11.
The film is then wound onto the winding shaft 8. Then, the printer 10 receives the label 9 based on a signal from a scale or the like.
Necessary information is printed on the label paper 5, and the required number of sheets are printed by sequentially sending the label paper 5. When printing is completed, the user hooks his/her finger onto the protrusion 33 to rotate the rotary blade 29. As a result, as shown in FIGS. 7 and 8, the blade portion 32 joins the cutting blade 28 from above to below in a point-contact state, thereby cutting the label paper 5. That is, the cutting blade 27 is biased in the direction of the rotating blade 29 by the compression springs 25 and 26, but when the contact point between the blade part 32 and the cutting blade 28 is located above, the cutting blade 27 is As shown in FIG. 8a, the lower part separates from the substrate 16, and as the contact point descends, the cutting blade 27 moves toward the substrate 16. At this time, if the blade part 32 and the cutting blade 28 are not in a perfectly straight line state, the force of the compression spring 25 is made smaller than the force of the compression spring 26, so that the blade part 32 and the cutting blade 28 are Point contact is maintained over the entire length, resulting in a good cut.

The label paper thus cut is pulled out and removed together with a holder fitted to the winding shaft 8.

In order to clean the printer 10, the locking button 40 is operated to remove it from the engagement hole 43 and the cutting unit 11 is opened, as shown in FIG.
Further, cleaning of the cutting unit 11 itself is performed by opening the cover 34 as shown in FIG. At this time, if the tension spring 31 is removed, the rotary blade 29 can be rotated as shown in FIG. 9, and paper dust etc. can be completely removed.

Effects of the device As mentioned above, this device is equipped with a linear cutting blade on one side of the paper path for label paper with a large number of labels pasted on a long backing paper, and the first and second cutting blades A cutting blade supported movably in the feeding direction of the label paper by a support shaft is provided, and a rotary blade having a blade portion is rotatably supported on the first support shaft, and the cutting blade is rotatably supported by the first support shaft. By providing elastic bodies on both ends of the cutting blade that bias the cutting blade toward the moving blade, the blade portion of the rotating blade is moved toward the cutting edge of the cutting blade by the first support shaft as the rotating blade rotates. Since they are joined elastically from the side toward the second spindle side in a point contact manner, the cutting point is one point even if the label paper is not specially pressed, and the cutting point can be rotated. As the blade rotates, it moves over the cutting blade, resulting in smooth cutting.Furthermore, since both ends of the cutting blade are elastically biased, it is difficult to determine which position on the cutting blade. The sharpness is the same, and the position of the rotating blade is fixed, so
This has the advantage that the cutting position relative to the label is stable in a straight line and a clean cut edge can be obtained.
