Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a printing mechanism for printed matter for printing numbers on promissory notes, gift certificates, etc. This relates to a printing mechanism that prints on multiple pages.

[Prior art and its problems]

For example, in the case of a check, as shown in Figure 3, the copy 1
When the number is printed in each location with a structure that can be separated from the certificate 2, the printing positions 3 and 4 may be different in the vertical direction. When this printing was performed using a flat stand, adjustment could be easily made by simply changing the position of the printing device.

However, when printing by rotary printing, as shown in FIG. A printing device (not shown) was fixed to the rings 7 and 8 in alignment with the mounting reference lines 9 and 10. When printing with different printing positions in the vertical direction as described above, printing was performed by shifting the printing device attached to one mount ring by a predetermined amount from the mounting reference line.
This was done by trial and error, and it took a considerable amount of time to precisely match the position of the printing device attached to the matt ring.

As a printing ring that has improved this drawback, a printing ring has been proposed in which a scale is provided around the entire circumference of the mount ring, and a printing device is attached to the mount ring in alignment with the scale. However, with this structure, it is not possible to instantaneously identify the positions of the initially installed printer that are equally divided by the number of printers to be installed, and the positions must be calculated, which poses the risk of incorrect installation positions.

[Problem to be solved]

To obtain a printing mechanism that allows a printing device to be attached to a mount ring accurately and in a short time even when printing at different vertical positions using a rotary printing method.

[Means for solving problems]

The printing mechanism is mounted on a rotating shaft with a mount ring provided with mounting reference lines at equal intervals on the circumference, and a rotatable correction ring with the same diameter as the mount ring and at the same spacing as the mount ring. Fix the mount ring with the mounting reference line and correction reference line, and attach the printing device to one mount ring in alignment with the installation reference line, and attach the printing device to the other mount ring in alignment with the correction reference line. The structure is as follows.

[Effect]

Using the mount ring without a correction ring as a reference, adjust the correction ring by the amount of displacement of the printing position from the mounting reference line of the mount ring provided on both sides of the mount ring with a correction ring, aligned with the reference line of the mount ring. By rotating the correction reference line from the mounting reference line and installing the printing device in line with this correction reference line, the positions of the printing device of the mount ring without a correction ring and the printing device of a mount ring with a correction ring can be determined. is displaced by the rotation of the correction ring, and the printing position is determined relatively accurately.

〔Example〕

In the embodiment of the present invention, as in the printing example shown in Fig. 3, which is the same as the conventional example, the printing at printing position 3 of copy 1 and the printing at printing position 4 of certificate 2 are sequentially printed using a rotary printing device. The case will be explained according to the drawings.

FIG. 1 shows the state of the mount ring before the printer is attached, and it consists of a shaft 20, mount rings 23 and 27, and a correction ring 24.

Among these, the shaft 20 has a rotatable rod-like structure, and has a structure in which a fixing groove 21 extends in the extension direction.

One mount ring 23 has a short fixed body in the shape of a circular tube with both ends partially cut out, and the shaft 20 is fixed in a fixing groove 21 so as not to move in the rotational direction.

As shown in Fig. 5, the other mount ring 27 has a cylindrical shape in which the body of the one mount ring 23 is a short cylinder with both ends partially cut off, and only the correction ring portion is cut on the surface of the central part of the cylinder. As with the mount ring 23, there is a fixing groove 2 on the shaft 20.
1, it is fixed so that it does not move in the direction of rotation.

The mount ring 27 has the mount ring 27
The surface of the cylindrical part and the surface of the mount ring 27 have the same diameter.
An annular correction ring 24 is provided in the center of the mount ring 27 and is rotatably fitted into the mount ring 27.

Mounting reference lines 22 and 25 are provided at equal intervals on the surfaces of the cylindrical portions of the mount rings 23 and 27. The mounting reference lines 22 and 25 are fixed by the fixing groove 21 via the mount rings 23 and 27 so that they are at the same position in the vertical direction.

The correction ring 24 is provided with a correction reference line 26 that is different from the mounting reference line 25 and can set the vertical position.

Next, the printing device 28 is attached as shown in FIG. 2 in alignment with the attachment reference line 22 of the mount ring 23 in FIG. In this example, the mount ring 23 has four attachment reference lines 22, so in this case four printing devices 28 are also attached. Similarly, align another mount ring 27 with the correction reference line 26 on the printer 2.
Give it an 8.

At this time, rotate the correction ring 24 so as to shift the correction reference line 26 from the installation reference line 25 by the rotation of the print position corresponding to the vertical distance between the print position 3 on the copy 1 and the print position 4 on the certificate 2. , Fix the correction ring fixture 33 fixed with a screw at a predetermined position in the elongated hole.

In this way, the vertical distance between the printers 28 is shifted in accordance with the distance between the printing positions 3 on the copy 1 and the printing position 4 on the certificate 2 in the vertical direction, and the desired printing is performed. .

During actual printing, this shaft rotates to sequentially print numbers and other information.

Furthermore, by providing a plurality of such configurations, it is possible to print in many positions.

[Effect of idea]

Since the printing mechanism of the present invention has the above-mentioned configuration, once the amount of displacement of the correction reference line of the mount ring, which has a correction ring to match one of the mount rings, from the installation reference line is determined, the correction ring can be aligned with the correction reference line. Since a printing device can be attached, the time required for conventional printing positioning is reduced by approximately 30 minutes.
It can be installed easily without requiring any skill or intuition.
