Abstract

(57) [Summary] [Purpose] To improve print quality. An inkjet print head 5 and a serial dot matrix print head 6 facing the platen 1 are mounted on a carrier 2, and the heads 5 and 6 print on the laminated copy paper 7. The inkjet print head 5 and the serial dot matrix print head 6 are mounted on the carrier 2 side by side in the stretching direction of the platen 1, and the inkjet print head 5 prints on the first sheet of the laminated copy paper 7. The serial dot matrix print head 6 is directly stamped on the first sheet of the laminated copy paper 7 to print on the second and subsequent sheets of the laminated copy paper 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a serial printer that prints on laminated copy paper used for forms and slips.

[0002]

[Prior Art]

 In this type of printer, an impact-type print head is mounted facing the platen on a carrier that is movable in parallel with the platen, and this impact-type print head is used to stack laminated copy paper via an ink ribbon. It can be printed. That is, the first sheet of the laminated copy paper is printed by the impact type print head through the ink ribbon, and at the same time, the second and subsequent sheets are copied by the printing pressure so that the laminated copy paper can be printed. It has become.

[0003]

[Problems to be solved by the device]

 However, since the impact type print head with a low resolution prints the first sheet of the laminated copy paper, the resolution of the first sheet of the laminated copy paper is low, and the impact type print head and the laminated copy paper have a low resolution. Since a large printing pressure cannot be obtained due to the interposition of the ink ribbon between the sheet and the sheet, the second and subsequent sheets of the laminated copy paper cannot be printed with high clarity and there is a problem that the printing quality is poor.

An object of the present invention is to provide a serial printer that can improve print quality.

[0005]

[Means for Solving the Problems]

 The serial printer according to the present invention includes a carrier movably provided in parallel with the platen, a non-impact print head mounted on the carrier so as to face the platen, and a non-impact type print head for printing on the first sheet of laminated copy paper. Is mounted on the carrier so as to face the platen side by side with the non-impact type print head in the stretching direction, and is directly stamped on the first sheet of the laminated copy paper to print on the second and subsequent sheets of the laminated copy paper. And an impact type print head.

[0006]

[Action]

 According to the present invention, since the first sheet of the laminated copy paper is printed by the non-impact type print head having high resolution, the resolution of the first sheet of the laminated copy paper is enhanced. Further, since the first sheet of the laminated copy paper is directly printed by the impact type print head, a large printing pressure is obtained, and the printing of the second and subsequent sheets of the laminated copy paper becomes highly clear.

[0007]

【Example】

A serial printer to which the present invention is applied will be described with reference to the drawings. In this printer, as shown in FIGS. 1 and 2, a carrier 2 is provided movably in parallel with the platen 1 via a pair of guide shafts 3 and 4.

An ink jet print head 5 as a non-impact type print head and a serial dot matrix print head 6 as an impact type print head, which are opposed to the platen 1, are mounted on the carrier 2, and these heads 5, 6 are mounted. Therefore, the laminated copy paper 7 is printed. The laminated copy paper 7 is wound around the platen 1 and conveyed by the rotation of the platen 1 in the arrow B direction.

The inkjet printhead 5 and the serial dot matrix printhead 6 are mounted on the carrier 2 side by side in the extending direction of the platen 1. The ink jet print head 5 is designed to print on the first sheet of the laminated copy paper 7, and the serial dot matrix print head 6 is directly printed on the first sheet of the laminated copy paper 7 to produce the laminated copy paper. The second and subsequent sheets of No. 7 are printed.

That is, the inkjet print head 5 and the serial dot matrix print head 6 move in parallel with the platen 1 by the movement of the carrier 2, and at the time of this movement, the inkjet print head 5 prints on the first sheet of the laminated copy paper 7. , The serial dot matrix print head 6 is directly printed on the first sheet of the laminated copy paper 7 without the ink ribbon, and the printing pressure is used to copy the second and subsequent sheets of the laminated copy paper 7. Has become.

According to the above configuration, since the first sheet of the laminated copy paper 7 is printed by the inkjet print head 5 having a high resolution, the resolution of the first sheet of the laminated copy paper 7 is increased and the laminated copy paper 7 is increased. The print quality of the first copy sheet 7 is improved.

Further, since the first sheet of the laminated copy paper 7 is directly printed by the serial dot matrix print head 6, a large printing pressure is obtained, and the printing of the second and subsequent sheets of the laminated copy paper 7 is high. It becomes clear and the printing quality of the second and subsequent sheets of the laminated copy paper 7 is also improved. Further, since the second and subsequent sheets of the laminated copy paper 7 are printed clearly, the number of copies can be increased.

In the above embodiment, the inkjet print head 5 is used as the non-impact print head, but the print head is not limited to this, and another print head such as a thermal print head may be used.

[0014]

[Effect of the device]

 As explained above, according to the serial printer of the present invention, the resolution of the first sheet of the laminated copy paper is enhanced, and the printing of the second and subsequent sheets of the laminated copy paper is highly vivid and the print quality is high. It has an excellent effect of being improved.
