Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer (including a copying machine) device having a mechanism for cutting a non-printed area of printed paper.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view of a conventional printer device, and FIG. 13 is a sectional view of FIG. In these figures, 1 is a main body case, 2 is a sheet, 3 is a sheet feeding cassette for storing and feeding the sheet 2, 8 is an ink sheet cassette, and 120 is a discharge tray for receiving the printed sheet 2. It is provided so as to project laterally from the body case 1. 4 is paper 2
Is a sheet feeding roller for feeding the sheet in the right direction in the drawing, 5 is a platen roller, and 6 is located below the platen roller 5.
A lower pinch roller 7 for controlling the sheet feeding of the sheet 2 is located above the platen roller 5, and an upper pinch roller 81 for controlling the sheet feeding of the sheet 2 at the time of printing is built in the ink sheet cassette 8. Ink sheet, 9 are thermal heads equipped with heating resistors, 10, 50, 51, 5
Numerals 2 and 53 are both transport rollers for transporting the sheet 2 in the left-right direction in the figure, and numeral 60 is a rotatable guide disposed inside the apparatus.

Reference numeral 13 is a cutter as a cutting mechanism for the non-printing area of the paper 2, 21 is a tip paper piece cut from the paper 2 by the cutter 13, and 22 is an output paper after the tip paper piece 21 is cut from the paper 2. . Reference numeral 17 denotes a paper piece receiving portion that projects from the side of the main body case 1 and stores the front end paper piece 21.
Reference numerals 8 and 19 denote an upper guide and a lower guide, respectively, which serve as guides for the paper 2. Also, a, b, c, d, e, f, g
A curved line with a mark indicates a trajectory traced by the leading end of the paper 2 or the output paper 22.

FIG. 14 is a partially enlarged view of FIG. 13, in which X is the paper 2 wound around the platen roller 5 and the ink sheet 8
1 shows the distance between the position p at which 1 is thermally transferred by the thermal head 9 and the contact position q between the paper 2 and the upper pinch roller 7. Similarly, Y indicates the distance between the position p and the contact position r between the sheet 2 and the lower pinch roller 6.

Next, the operation will be described. In FIG. 13, one sheet 2 is fed from the sheet feeding cassette 3 by the sheet feeding roller 4. Next, the platen roller 5 rotates counterclockwise, and the paper 2 is wound around the platen roller 5 with a constant tension between the lower pinch roller 6 and the upper pinch roller 7. In this state, the thermal head 9 is brought into pressure contact with the paper 2 via the ink sheet 81, so that the printing portion of the ink sheet 81 is printed on the paper 2 by thermal transfer. The platen roller 5 continues to rotate, and the leading edge of the sheet 2 moves leftward in the figure while the image is printed.

Here, for example, in a printer device that performs color printing, the paper 2 reciprocates several times on the platen roller 5 for each primary color of yellow, magenta, and cyan. If the tension of the paper 2 fluctuates during this reciprocating operation, a relative positional deviation between the paper 2 and the paper pressure contact surface of the platen roller 5 occurs, which causes color misregistration. Therefore, it is essential that the paper 2 is wound around the platen roller 5 with a constant tension by the lower pinch roller 6 and the upper pinch roller 7 during printing.

Therefore, as shown in FIG. 14, a position p at which the paper 2 is thermally transferred by the ink sheet 81 and the thermal head 9 and a position where the leading end of the paper 2 is sandwiched, that is, the upper pinch roller 7 of the paper 2. Distance X with contact position q
Is required for paper 2. The range of this distance X is
The ink sheet 81 is not transferred at the tip of the non-printing area. Similarly, the range of the distance Y is the non-printing area at the rear end. These X and Y appear in the range shown in FIG. In the figure, 2a is cut by a cutter 13 and is cut into two pieces of tip paper 2.
The area of 1 is referred to as the leading edge non-printing area, and the area of 2b is the area of the output paper 22 and is referred to as the output area.

As a method for narrowing the leading edge non-printing area 2a, for example, Japanese Patent Laid-Open No. 62-103168 proposes a method in which a sensor detects the leading edge of the sheet and pulls the sheet back by a predetermined amount. However, even by this, the width of the front end non-printing area cannot be made smaller than the distance X.

Therefore, after printing as shown in the figure, the sheet 2 is conveyed outside the apparatus by the conveying rollers 10, 50, 51 and 52.
A printer device has been announced in which the paper is conveyed to a position, the front end non-printing area 2a of the paper 2 is cut by a cutter 13, and the cut front paper piece 21 is discharged and accumulated in a paper piece receiving portion 17 provided outside the apparatus.

After printing the sheet 2, the conveying rollers 10, 5 are printed.
It is guided leftward in the figure by the rotation of 0 and 51, and is fed to the conveyance roller 52 at the d position. Then, the transport roller 52
Is guided to the cutter 13 and the tip non-printing area 2a is cut there. The cut front paper piece 21 is discharged and accumulated in the paper piece receiving portion 17. Next, the transport roller 5
2 is rotated in the opposite direction to reversely feed it until the leading edge of the output paper 22 returns to d, and then stopped, and at the same time, the guide 60 is rotated counterclockwise (chain line position in the figure) and cut. The leading edge of the output paper 22 is directed from d to f. Output paper 2
When the front end of 2 comes to the position f, the transport roller 51 rotates again in the original direction, and the output paper 22 is sent to the left in the drawing,
Subsequently, after being conveyed by the conveying roller 53, the sheet discharge tray 1
20 is discharged and accumulated.

[0011]

As described above, in the conventional printer device, since the cutter for cutting the non-printing area is arranged in the main body case 1 at a position apart from the printing portion, the output is carried out like the conveying roller 52. There is a problem that a mechanism for changing the traveling direction of the paper 22 is required, and the non-printing area at the rear end of the paper 2 cannot be cut and remains as it is.

The present invention has been made to solve the above problems, and can cut not only the non-printing area at the leading edge of the paper but also the non-printing area at the trailing edge, and the transport roller is rotated in the reverse direction. The purpose is to obtain a printer device that does not require complicated control.

[0013]
