Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut sheet issuing apparatus having a function of cutting a continuous sheet and issuing a cut sheet such as a label.

[0002]

2. Description of the Related Art Generally, an apparatus of this type will be described with reference to FIGS. First, a print head 2 is resiliently brought into contact with a platen 1 formed in a roll shape, and a release sheet 4 is attached to a long mount 3 between the print head 2 and the platen 1. Printed paper 5 is inserted. On the downstream side of the printing unit by the print head 2, there is provided a release plate 6 for sharply bending the mount 3 to release the release paper 4. At the tip of the print head 2, a cutting blade 7 which is opposed to the peeling plate 6 with a predetermined space is fixedly provided. This cutting blade 7 is formed in a sawtooth shape perpendicular to the longitudinal direction of the release paper 4, and
It is formed so as to project obliquely forward.

In such a structure, printing is performed by the print head 2 while feeding the print paper 5. At this time,
Since the mount 3 is bent by the release plate 6, the release paper 4 is separated from the mount 3. Then, the release paper 4 protruding from the release plate 6 is separated at the cutting blade 7 by holding the leading end of the release paper 4 by hand, and is used as a label or a receipt.

[0004]

When the peeling paper 4 is cut by the cutting blade 7, there is a gap between the peeling plate 6 and the cutting blade 7, so that the peeling paper 4 is cut only by biting into the cutting blade 7. That is, the release paper 4 itself is not pressed. Therefore, the sharpness of the release paper 4 is not always good. That is, since a part of the release sheet 4 must be cut in a floating state, it is difficult to cut at a certain position reliably and with good sharpness.

[0005]

Means for Solving the Problems A printing paper in which a release paper is adhered to a long backing paper, a printing section for printing on the release paper of the printing paper, and the release paper by sharply bending the mounting paper And a cutting blade provided in a direction orthogonal to the longitudinal direction of the release paper, and a printing paper holding unit for holding the printing paper between the cutting blade and the peeling unit.

[0006]

The printing paper on which predetermined items are printed by the printing unit is issued after the release paper is peeled off by the peeling unit. When the release paper is cut by the cutting blade, the release paper is cut by the cutting blade and the peeling unit. Therefore, the cutting edge is sandwiched by the printing paper holding portion, so that the cutting edge can be bite well, so that the sharpness is good and the cutting at a certain position can be surely performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. First, the frame 12 is provided inside the housing 11.
The printer unit 14 is formed on one surface of the vertical wall 13 of the frame 12. The vertical wall 13
A support portion 15 extending in the horizontal direction is integrally provided on the upper edge, and each component of the printer unit 14 is attached to the support portion 15. That is, the head holding plate 18 is attached to the printer frame 16 by the fulcrum shaft 17.
Are mounted so as to be able to be raised and lowered, and the head mounting plate 19 is also mounted so as to be able to be raised and lowered. The head mounting plate 19 is provided with a support shaft 20 projecting therefrom, and the head pressing plate 18 is formed with a shaft hole 21 through which the support shaft 20 is inserted. A compression spring 22 is attached to the support shaft 20 provided in this manner, and the head attachment plate 19 is attached downward with respect to the head holding plate 18 positioned by the printer frame 16 by the compression spring 22. It is being rushed. Further, a print head 23 is mounted on the head mounting plate 19. Further, the print head 2 is provided on the printer frame 16.
A platen 24 in the form of a roll is attached to face the platen 3, and a driving unit (not shown) is connected to the platen 24. Next, a peeling plate 25 as a peeling section is attached to the printer frame 16.
The peeling plate 25 can be moved vertically by a spring 26, and is fixedly and resiliently attached in the front-rear direction.

Next, a release sheet 28 is placed on the long backing sheet 27.
Is affixed to form a printing paper 29, and this printing paper 2
9 is wound in a roll shape and held on a holding shaft 30. The print paper 29 passes between the print head 23 and the platen 24, and only the mount 27 is bent by the peeling plate 25 and wound by a winding shaft 31 connected to a drive unit (not shown). Further, a sensor 32 for detecting the presence or absence of the printing paper 29 is provided in the insertion path of the printing paper 29.
Is provided. Further, a sensor 33 for detecting the presence or absence of the peeled release paper 28 is provided near the release plate 25.

A cutting blade 35 having a serrated cutting portion 34 formed in a direction perpendicular to the longitudinal direction of the printing paper 29 is mounted on the front surface of the head mounting plate 18. The cutting blade 35 is detachably attached by two fixing screws 36. And
The cut portion 34 is formed so as to protrude horizontally toward the front, and the lower surface thereof abuts on the peeling plate 25, whereby
A printing paper holding portion 37 is formed.

In such a configuration, the printing paper 29 is sent out by the driving rotation of the platen 24, and printing is performed on the surface of the release paper 28 by the printing head 23. Then, the printing paper 29 by the platen 24
The take-up shaft 31 is also driven at the same time as the feeding, and the mount 27 is wound. The tensile force on the mount 27 is the platen 2
4 is set so as not to affect the feeding of the printing paper 29 by the backing sheet 4, but the backing sheet 27 is pulled in a tensioned state so that the backing sheet 27 is sharply bent at the position of the peeling plate 25, whereby the peeling sheet 28 Is peeled off from the mount 27 and protruded forward. At this time, the peeling plate 25 is pressed down by the cutting blade 35 and is slightly sunk. In this state, the force from the winding shaft 31 acts on the peeling plate 25, but the force acts in the backward direction and does not act in the vertical direction, so that the peeling plate 25 does not move.

When the necessary items are printed as labels or receipts, the release paper 28 peeled off by the release plate 25 is cut by the cutting blade 35. In the cutting, the paper is projected forward as in the prior art. The leading edge of the release sheet 28 is grasped and pulled upward. As a result, the release paper 28 of the printing paper 29 held between the cutting blade 35 and the release plate 25 is cut by the cutting portion 34 of the cutting blade 35 while being held by the printing paper holding portion 37, Cut with good sharpness. Also, the cutting position is accurate, and the cutting position does not shift during cutting. The release paper 28 formed continuously in this manner becomes a label or a receipt of an arbitrary length.

Next, the peeling plate 25 shown in FIG. 7 is formed by bending a plate material, and any shape can be used as long as it has an acute angle portion at the tip. .

[0013]

According to the present invention, as described above, a printing paper in which a release paper is stuck to a long backing paper, a printing portion for printing on the release paper of the printing paper, and the mounting paper are bent sharply. A peeling section that peels off the release paper, a cutting blade provided in a direction orthogonal to the longitudinal direction of the release paper, and a printing paper holding section that holds the printing paper between the cutting blade and the peeling section. Since the printing paper on which the predetermined items are printed in the printing section is issued because the peeling paper is peeled off at the peeling section, when the cutting paper is cut with the cutting blade, the peeling paper is cut with the cutting blade and the peeling section. Since the paper is held by the printing paper holding portion, the cutting edge is well bitten, whereby the sharpness is good and the cutting at a certain position can be surely performed.
