Abstract

(57) [Summary] [Purpose] A line-type thermal transfer recording device that uses cut printing paper is equipped with a cutter that cuts the printing paper, thereby making it possible to print on the entire printing paper. [Structure] A thermal transfer recording device that has a means for holding one or both ends of cut printing paper and performs overlapping printing by reciprocating the printing paper has the disadvantage that the holding margin cannot be used for printing, resulting in a dead space. . Therefore, a cutter for cutting the printed paper is arranged on the paper discharge side of the clamping means, and the dead space is cut off after printing is completed, so that the print can be printed on the entire printed paper.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention comprises means for gripping one or both ends of the cut printing paper. The present invention relates to a recording device that performs overlapping printing by reciprocating printing paper.

0002

[Conventional technology]

As shown in Figure 4, the paper feeding method of conventional recording devices is, for example, by feeding one end of the printed paper into the It is held between two rollers, the push roller 2 and the pinch roller 3, and the roller is used as a reference. Overlapping printing was performed by moving the printing paper back and forth.

0003

[Problem that the idea aims to solve]

However, in the conventional paper feeding method, from the means of gripping the printing paper to the printing heating element, It is not possible to print at this distance, and the gripping space becomes a dead space. , it was impossible to print completely on printing paper.

0004

[Means to solve the problem]

In order to solve the above problem, in this invention, paper is cut on the paper ejection side of the means for gripping the printed paper. By placing a cutter to cut the dead space and cutting the dead space after printing is completed, the result is It is now possible to print on a full sheet of printing paper.

[0005]

[Effect]

With the above configuration, it is possible to print all the information on the printing paper.

[0006]

【Example】

Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a diagram schematically showing the mechanism of the present invention. Sent from paper feeder 7 The printing paper 11 is held between the paper feed rollers 10 and conveyed through the paper guide 8, and then transferred to the platen. After passing through 4, it is sandwiched between two rollers, namely capstan roller 2 and pinch roller 3. held. After this, the printing paper is conveyed using the two rollers as a reference, and printing (not shown) is carried out. The printing start position is determined by the start position determining means. Thermal print head 5 , the printing paper 11 and the ink sheet 6 are sandwiched between the platen 4 and a thermal pulse is generated to print. do. The ink sheet 6 has three colors, yellow, magenta, and cyan, and A color image is obtained by sequentially overlapping and printing on the printing paper 11 that is reciprocated by the means. .

[0007] By the way, the printing paper 11 is held between the capstan roller 2 and the pinch roller 3 like this. In this method, the leading edge of the printing paper 11 is exposed to a thermal beam as shown in FIG. From the heating element center 5a of the lint head 5 to the capstan roller 2 and pinch roller 3 The pinched distance a becomes a dead space where printing cannot be performed. Also printing paper At the rear end of 11, as shown in FIG. The distance b from which the paper is latched to the paper guide 8 becomes a dead space because printing cannot be performed. Become. The dead space can be used for printing paper 1 even if the paper feeding method mentioned in the embodiment is not used. If there is a method of holding 1, it exists.

[0008] In this invention, a capstan roller 2 and a pinch roller are used as a means to pinch the printing paper. A cutter 1 for cutting paper was arranged on the paper discharge side of the paper cutter 3 as shown in FIG. Next, explain its operation do. When three-color printing is completed, the printing paper 11 is in the position shown in FIG. 3. paper not shown there The feed motor is reversed and the print start position determining means moves the printing paper 11 as shown in FIG. Return to position. Next, the paper feed motor is rotated in the normal direction, and when the paper has been fed a distance a, the cutter 1 is turned on. Move it and cut off the dead space at the tip. Furthermore, the paper feed motor is rotated in the forward direction. After feeding the distance corresponding to the printing area, operate cutter 1 again to remove the dead space at the rear end. cut off the base. Finally, rotate the paper feed motor in the normal direction again to remove the dead space at the rear end. The print operation is completed by discharging the base amount. As a result, the printing paper 11 cannot be completely printed. I can do that.

[0009] With this invention, if you want a standard size, for example, A4 portrait, you can print on a full printing paper. It can be obtained by preparing printing paper with a total length of (a + 297 + b) mm. .

0010

[Effect of the idea]

According to the present invention, the cutter in the recording device cuts the unprinted sheets before and after the printing paper. By cutting out the blank space, it is possible to print on a full sheet of printing paper. It can also be used as a printer, printing pages on the edges of paper.
