Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printer, and particularly to a printer equipped with a tractor feeder that automatically feeds continuous paper.

(Prior Art) Generally, when continuous paper is used in a printer, the paper is automatically fed by a tractor feeder.

This tractor feeder has a tractor unit including a tractor body having a pin, a tractor support disposed to sandwich the tractor body from both sides, and a tractor cover, and the paper is placed on both sides of the tractor unit. The formed feed hole is set so as to be engaged with the pin of the tractor body, and is held down by the tractor cover. By rotating the tractor body, continuous paper is automatically fed and printing can be performed continuously.

However, with such conventional printers,
Since the recorded continuous sheets were simply folded and placed one on top of the other, unnecessary sprocket holes had to be manually cut off from the recorded sheets, which was troublesome. In particular, in order to file and store paper, the sprocket holes on one side can be used for filing, but the sprockets on the other side are unnecessary and undesirable in terms of appearance.

Conventionally, perforations were made inside the feed holes on the other side of the continuous paper to facilitate separation.

However, the perforation hole portion still has to be separated manually, which is a tedious task.

(Purpose of the invention) Therefore, the present invention eliminates the trouble of automatically cutting off the spout hole portion of the recorded paper by providing a cutting mechanism in the tractor unit to cut off the spout hole portion of the recorded paper. The purpose is to make it easier to organize and file recorded forms.

(Structure of the Invention) In order to achieve the above object, the present invention provides a printer equipped with a tractor feeder that automatically feeds continuous paper with feed holes formed on both sides. It is characterized by being equipped with a cutting mechanism that separates the feed hole portion.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 6 are diagrams showing one embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a printer, and printer I is attached with a tractor feeder 2 that automatically feeds continuous paper. The tractor feeder 2 is connected to the housing 3 of the printer 1.
a side plate 4.5 fitted into the side plate 4.5, a guide rail 6.7 passed between the side plates 4.5, a pair of tractor parts 8a and 8b movably attached to the guide rail 6.7, As shown in FIGS. 2 to 6, each of the tractor parts 8a and 8b includes a tractor body 10 having a pin 9, and a tractor support 11 disposed to sandwich the tractor body 10 from both sides. .12, and a tractor cover 14.1 that sandwiches the continuous paper 13 between the tractor body 10 and the tractor support 11.12 on the upper and lower surfaces.
5. The paper 13 has feed holes 16a and 16b formed on both sides thereof, and the feed hole 1 is formed inside the feed hole 16b on the right side (the right side in FIG. 2) with the printed side facing up.
A perforation 17 is provided in the longitudinal direction (vertical direction) of the paper 13 along the line 6b. The paper 13 is set in the tractor feeder 2 so that the feed holes 16a and 16b are engaged with the bin 9 of the tractor main body 10, and the tractor main body 10 is driven by the rotation of the guide rail 6 to feed the paper 13.

, In the tractor section 8b on the right side in Fig. 1.2, the parts shown in Fig. 3~
A cutting mechanism 18 shown in FIG. 4 is provided.

That is, when the paper 13 is set on the tractor body 2, the tractor support 12 located inside the paper 13 has a groove 1.
9 is formed at the rear end in the paper discharge direction (arrow direction in FIG. 2), and a cutting tool 20 is housed in the groove 19. The cutting tool 20 has a substantially U-shape, and is rotatably supported by a shaft 21 at its center.

A blade 22 is formed at one end of the cutting tool 20, and a protrusion 23 (biasing means) that can protrude from the tractor support I2 is formed at the other end, and the tip thereof has a smooth flat surface. Further, the cutting tool 20 is biased by a spring 24 in a direction in which the blade 22 is housed in the groove 19. That is, the spring 24 is provided between a projection 25 formed on the blade 22 side of the shaft 21 of the cutting tool 20 and a projection 26 formed on the tractor support 12, and its elastic force causes the cutting tool 20 to move toward the shaft 21. Rotate counterclockwise in Fig. 3.4 around . The tractor cover 14 also has a blade 22.
A groove 27 is formed at a position facing the blade 22, and when the blade 22 protrudes outside the tractor support 12, its tip enters into the groove 27, as shown in FIG. The blade 22 cuts the perforation 17 when the paper 13 is set on the tractor feeder 2.
In other words, the blade 22 is disposed at a position facing the perforation 17.

In Fig. 5.6, 28 is a fixing lever that fixes the tractors 8a and 8b at appropriate positions on the guide rail 6.7, and 29 is a fixing lever that is interposed between the tractor covers 14 and 15. This is a spring that biases in the closing direction.

Next, the action will be explained.

To set the paper 13, first, the tractor main body 10
is moved along the guide rail 6.7 to match the width of the paper 13, and fixed to the guide rail 7 with the fixing lever 28.

Open the tractor cover 14.15 and remove the tractors 8a and 8b.
1. Close the tractor cover 15 by aligning the feed holes 16a and 16b of the paper 13 with the pin 9 of the tractor main body 10 from the lower part of the machine. Next, the paper 13 is similarly set on the upper part of the tractor 8a18b via the platen of the printer 1. At this time, although the tractor 8b is provided with a cutting mechanism 18, the blade 22 of the cutting tool 20 is housed in the groove 19 by a spring 24, so safety is ensured when setting the paper 13, and there is no need to inadvertently The paper 13 is never cut. Align the feed holes 16a and 16b of the paper 13 with the pin 9 of the tractor main body IO, and then insert the paper 1 with the tractor cover 14.
3, the protrusion 23 of the cutting tool 20 is pushed by the tractor cover 14. By pressing the protrusion 23,
The cutting tool 20 rotates about the shaft 21, and the blade 22 projects out of the tractor support 12, cuts through the perforation 17 of the paper 13, and enters the groove 27. After that, printing will start,
When the tractor main body 10 is driven by the rotation of the guide rail 6 to feed the paper 13 in the paper ejection direction, the perforation 17 portion of the paper 13 is cut by the blade 22 . Therefore, the paper 13 on which recording has been completed by the printer 1 is automatically cut off at the feed hole 16b portion. As a result, it is possible to save the effort of manually separating the spout hole 16b portion from the recorded paper 13, and it is possible to easily and easily file and organize the recorded paper 13.

In the above embodiment, since the cutting mechanism is provided at the rear end of the tractor support in the paper ejection direction, the paper can be easily cut without interfering with the paper feeding action of the tractor unit. In order to further enhance the effect,
The paper may be pulled downward using a paper guide, a net, or the like.

In addition, if the perforation position of the paper differs depending on the paper, multiple grooves are formed in the shaft that supports the cutting tool in a direction perpendicular to the axial direction, and cutting is performed in the groove corresponding to the perforation position among the grooves. This can be achieved by providing a position adjustment mechanism that aligns the blade with the perforation by inserting a tool.

Furthermore, it goes without saying that the present invention can also be applied to paper without perforations.

(Effects) According to the present invention, by providing the tractor unit with a cutting mechanism that cuts off the spout hole portion of the recorded paper, the spout hole portion of the recorded paper can be automatically cut off. This eliminates the hassle of separating the sheets and makes it easier to organize and file the recorded sheets.
