[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing device for printing characters and graphics on a printing paper, and more particularly to a printing paper cutting member.

[0002]

[Prior Art]

 As shown in FIG. 5, the structure of the conventional printing device is such that the printing paper cutting member 22 is mounted on the upper surface of the printing device main body 21, and the main part of the DD cross section has the structure as shown in FIGS. there were.

That is, in FIG. 3, FIG. 4, and FIG. 5, 21 is a printer main body, 22 is a printing paper cutting member, 23 is printing paper, 22 A is the cutting edge of the printing paper cutting member 22, and 24 is a platen. In order to print on the printing paper 23 in cooperation with the non-printing head, 25 is a paper feed roller for discharging the printing paper 23, and the blade edge 22A of the printing paper cutting member 22 is the platen 24 and the paper feeding roller. From the extension line C of the straight paper path between 25, the printing paper 23 is deflected to the front side (left side in the drawing) so as not to hit the printing paper cutting member 22 in FIG. 3, or noise in FIG. In order to prevent it, it was common to deviate to the back side (right side in the figure) to close the opening as much as possible.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, it is necessary to greatly pull the printing paper 23 toward the front side when cutting the printing paper 23 in FIG. 3, and in FIG. There is a problem in that the printing paper 23 is deformed because it hits the printing paper cutting member 22 when the paper is fed in, or the printing paper 23 is caught and a predetermined amount of paper cannot be fed.

Therefore, the present invention has been made in order to solve such a conventional problem, and an object thereof is to prevent the printing paper 23 from being deformed and to feed the printing paper 23 by a predetermined amount. The purpose of the present invention is to provide a printing device that can reliably cut the printing paper 23 and that can be easily fed.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the printing apparatus of the present invention is a printing apparatus having a printing paper cutting member for cutting printing paper, in which the blade edge of the printing paper cutting member is a straight paper path between the platen and the paper feed roller. It is characterized by being provided on the extension line.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a main part of a cross section taken along the line AA in FIG. 2 of a printing device according to an embodiment of the present invention. 2 is a printing paper cutting member, 2A is a cutting edge of the printing paper cutting member, and 3 is The printing paper 4 is a platen for printing on the printing paper 3 in cooperation with a printing head (not shown), and 5 is a paper feed roller for discharging the printing paper 3.

Next, the positional relationship among the blade edge 2A of the printing paper cutting member 2, the platen 4 and the paper feed roller 5 will be described. The blade edge 2A of the printing paper cutting member 2 is a straight paper path between the platen 4 and the paper feed roller 5. It is arranged on the extension line B of.

By arranging the blade edge 2A of the printing paper cutting member 2 in this way, in the normal state, the printing paper 3 is deformed to the back side by its own weight as shown in FIG. It can be arranged without hitting the member 2.

Therefore, since the printing paper 3 does not hit the printing paper cutting member 2 in the normal state, the printing paper 3 is not deformed and the printing paper 3 is reliably fed by a predetermined amount. Further, since the cutting edge 2A is located on the extension line B of the straight paper path between the platen 4 and the paper feed roller 5, the printing paper 3 can be easily cut. Since the cutting edge 2A of the printing paper cutting member 2 can be arranged on the back side of the conventional example shown in FIG. 3, the opening can be made smaller than that of the conventional example shown in FIG. 3, and the noise reduction effect can be improved. It

As described above, according to the present invention, in the printing apparatus having the printing paper cutting member 2 for cutting the printing paper 3, the blade edge 2A of the printing paper cutting member 2 is placed between the platen 4 and the paper feed roller 5. Since it is provided on the extension line B of the straight paper path, the printing paper 3 is not deformed, the printing paper 3 is reliably fed by a predetermined amount, and the printing paper 3 can be easily cut. Can be provided.

[0013]

[Effect of the device]

 As described above, according to the present invention, it is possible to provide a printing device that does not deform the printing paper, reliably feeds the printing paper by a predetermined amount, and can easily cut the printing paper. Have.
