Abstract

PURPOSE: To provide a thin type printer by integrating a platen with a paper feed roller. CONSTITUTION: A paper feed roller 1 is rotated via a sub shaft 22 since a shaft 21 is rotated with a line feed motor 5, and paper 11 fixed with the paper feed roller 1 and a small roller is fed thereby. Thereafter, the shaft 21 becomes stationary, and a carriage 6 is driven by a carriage motor 10 via a pulley 91 and a pulley belt 92. Ink of an ink ribbon 8 is printed on paper 11 arranged between a printing head 7 and a platen 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device,
In particular, it relates to a printer device in which a platen and a paper feed roller are integrated.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional printer apparatus includes a paper feed roller 101 and the paper feed roller 101.
The small roller 4 that holds the paper 11 by the paper feeding roller 101 is held by the small paper feeding roller 101 and the small roller 4.
01 is rotated by the line feed motor 5, the paper 11 is fed, the carriage 6 is started by the carriage motor 10 via the pulley 91 and the pulley belt 92, and the print head 7
And the ink ribbon 8 on the paper 11 arranged between the platen 3 and the platen 3.
Ink is printed.

For this reason, the apparatus cannot be designed thinner than the total thickness of the height of the paper feed roller 101 and the diameter of the platen 3.

[0004]

As described above, in the conventional printer, since the paper feed roller and the platen are arranged independently, the thickness of the height of the paper feed roller and the diameter of the platen are combined. Below, there is a problem that the device cannot be designed thin.

Therefore, an object of the present invention is to provide a printer device which realizes a thin type by integrating a platen and a paper feed roller.

[0006]

In order to solve the above-mentioned problems, a printer device of the present invention is equipped with an ink ribbon and a print head, and the print head faces a paper to be printed via the ink ribbon. Carriage to be scanned by
A cylindrical paper feed roller covered with a belt having a shaft and two sub-shafts interlocking with the shaft, and a platen disposed between the two sub-shafts so as to face the print head, and a paper feed roller of the paper feed roller. It is characterized by comprising a motor for rotating the shaft to control the feeding of the paper and for controlling the scanning of the carriage.

Further, in order to solve the above-mentioned problems, the printer device of the present invention is characterized by being constituted by the paper feed roller provided with a plurality of the sub-shafts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a printer device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram (A) and a sectional view (B) of a printer device according to an embodiment of the present invention.

A printer device according to an embodiment of the present invention is
As shown in FIG. 1A, a carriage 6 on which an ink ribbon 8 and a print head 7 are mounted, and which is scanned by the print head 7 so as to face a paper 11 to be printed via the ink ribbon 8 and a shaft. 21 and two sub-shafts 22 interlocking with the shaft 21, and these two sub-shafts 22
A cylindrical paper feed roller 1 covered with a belt having a platen 3 arranged opposite to the print head 7 and a shaft 21 of the paper feed roller 1 are rotated to control the feeding of the paper 11. In addition, it is composed of motors 5 and 10 for controlling scanning of the carriage 6.

Further, the motors 5 and 10 are the paper feed rollers 1
Line feed motor 5 for rotating shaft 21 of
And a carriage motor 10 that controls the carriage 6 via a pulley 91 and a pulley belt 92.

Next, the operation of the printer according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1B, the operation of the printer apparatus according to the embodiment of the present invention is such that the shaft 21 of the paper 11 fixed by the paper feed roller 1 and the small roller 2 is a line feed motor. By being rotated by 5, the paper feed roller 1 is rotated via the sub shaft 22, and the paper 11 is fed.

Thereafter, during the printing operation, the shaft 21 stands still, the carriage 6 is started by the carriage motor 10 via the pulley 91 and the pulley belt 92, and the print head 7 is driven.
And the ink ribbon 8 on the paper 11 arranged between the platen 3 and the platen 3.
Ink is printed.

[0015]

As described above, according to the printer apparatus of the present invention, since the platen and the paper feed roller are integrated, the height of the paper feed roller and the combined thickness of the platen are not affected, and the apparatus is not affected. There is an effect of realizing the miniaturization and the thinning.
