Abstract

PROBLEM TO BE SOLVED: To provide a scanner printer device provided with a CCD sensor precisely reading image data of a medium. SOLUTION: When the medium 6 is inserted between a platen 3 and a printing head 1 before starting the reading of image data, a roller 7 is in the state of pushing the medium 6 to the platen 3 by the enlongation and contraction of a shaft 8. Consequently a CCD sensor 4 starts the reading of image data with the moving of a carriage 2 and the roller 6 is in direct contact with the medium 6 at the time of the moving of the carriage 2 to prevent the flawing of the medium 6 until all the image data of the medium 6 are read. In addition, while the shaft 8 is enlongated and contracted to perfectly press the medium 6 with contact with the platen 3, the CCD sensor 4 reads image data of the medium 6.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scanner printer, and more particularly to a CCD for reading image data of a medium.
The present invention relates to a scanner printer provided with a sensor.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional scanner printer apparatus includes a print head 1 for performing printing via an ink ribbon 5, a platen 3 provided to face the print head 1, and a platen 3. A carriage 2 mounted with an ink ribbon 5 and a print head 1 moving opposite to 3;
It comprises a medium 6 inserted between the platen 3 and the print head 1 from which image data printed or recorded is read, and a CCD sensor 4 arranged on the carriage 2 for reading the image data of the medium 6.

[0003]

However, in the conventional scanner printer device, since the CCD sensor is not completely parallel to the surface of the medium from which the image data is read, the image data which has been expanded and contracted is read from the image data of the actual medium.
In addition, since the image data at the bottom of the read row is read again as the image data at the top of the next row, there is a problem that the same image data continues at the boundary of each row of the read image data. .

Accordingly, an object of the present invention is to provide a scanner printer provided with a CCD sensor for accurately reading image data of a medium.

[0005]

In order to solve the above-mentioned problems, a scanner printer according to the present invention includes a print head for performing printing via an ink ribbon, and a platen provided to face the print head. A carriage on which the ink ribbon and the print head are mounted to move in opposition to the platen; a medium inserted between the platen and the print head, from which image data printed or recorded is read; and image data of the medium. A CCD sensor for reading, a carriage mounted with the ink ribbon and the print head and moved to face the platen, a roller for holding the medium, and the medium and the CCD
And a mechanism arranged on the carriage so as to keep a predetermined distance from the sensor.

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

FIG. 1 is a configuration diagram of a scanner printer according to an embodiment of the present invention.

As shown in FIG. 1, a scanner printer according to an embodiment of the present invention includes a print head 1 for printing via an ink ribbon 5 and a platen 3 provided opposite the print head 1. A carriage 2 on which an ink ribbon 5 and a print head 1 that move opposite to the platen 3 are mounted; a medium 6 that is inserted between the platen 3 and the print head 1 to read image data printed or recorded; CCD for reading image data of this medium 6
A sensor 4, a carriage 2 on which an ink ribbon 5 and a print head 1 are mounted and moves to face a platen 3, a roller 7 for holding a medium 6, and a medium 6
And a mechanical means arranged on the carriage 2 so as to keep the distance between the CCD sensor 4 and the CCD sensor 4 at a predetermined value.

The mechanism means includes a shaft 8 which is extendable and retractable between the roller 7 and the CCD sensor 4.
The CCD 2 is arranged on the carriage 2 so as to keep a predetermined distance between the CCD 2 and the CCD sensor 4.

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

As shown in FIG. 1, the operation of the scanner printer according to one embodiment of the present invention is as follows.
When the roller 7 is inserted between the rollers 6, the roller 7 presses the medium 6 against the platen 3 by the expansion and contraction of the shaft 8.

Accordingly, CC is moved with the movement of the carriage 2.
The roller 7 moves the carriage 2 until the D sensor 4 starts reading the image data and reads all the image data of the medium 6.
The CCD sensor 4 reads the image data of the medium 6 while directly contacting the medium 6 at the time of the movement, thereby preventing the medium 6 from being damaged, and expanding and contracting the shaft 8 to completely press the medium 6 against the platen 3. Perform

[0013]

As described above, according to the scanner / printer apparatus of the present invention, since the CCD sensor is always parallel to the surface of the medium from which the image data is read, it is possible to read the image data which does not expand and contract. In addition, since the image data of the read row is not read again in the next row, there is an effect of preventing the same image data from continuing on the boundary of each row of the read image data.
