DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper ruler used in a cutting machine for cutting paper and the like, and more particularly, to a method for easily positioning a paper ruler and eliminating a displacement of the paper ruler. The present invention relates to a positioning structure of a paper ruler.

[0002]

2. Description of the Related Art First, an outline of a typical paper cutting machine will be described with reference to FIG. The paper cutting machine is provided with a rail 2 extending along one end of a long side of a rectangular flat paper board 1, and one end of the rail 2 is held by a holding section 3. The other end of the screw 2 is lifted by a predetermined angle. Also, two guide rulers 7 are fixed to the paper table 1 at right angles to the rail 2 and in parallel with each other. A paper ruler 8 is provided so as to be movable.

When cutting the paper, the position of the paper ruler 8 is adjusted in advance according to the size of the paper to be cut, and the paper ruler 8 is fixed to the guide ruler 7.
The other end of the rail 2 is pivoted upward, and the paper is placed on the paper base 1 so as to be located between the rail 2 and the paper base 1, and the leading edge of the paper comes into contact with the paper ruler 8. With rail 2 tilted, rail 2
The locking claw 5 provided at the tip of the paper table is locked to the locking portion 4 provided on the paper base 1, and the paper is held between the upper surface of the paper base 1 and the paper holding plate 9 provided on the lower surface of the rail 2. And fix the paper so that By moving the slider 6 along the rail 2, the rotating blade held by the slider 6 cuts the paper while rotating.

The positioning and fixing of the paper ruler 8 are as follows.
Conventionally, this was performed as follows. That is, a magnet is attached to the back of the paper ruler 8 and the paper table 1, and the paper ruler 8 is moved and positioned against the magnetic force of the magnet.
The magnetic force fixed the paper ruler 8 to the paper table. As another means, as shown in FIG.
Screws are screwed into screw holes 801 provided at both ends of the paper hitting ruler 8, and the paper hitting ruler 8 is connected to the guide ruler 7 with the screws loosened.
The paper ruler 8 is fixed to the guide ruler 7 by tightening a screw.

[0005]

The above-mentioned conventional paper ruler 8 described above.
Positioning and fixing have the following problems.
First, in the case of using a magnet, if the attraction of the magnet is weak, when cutting, the hand of an operator touches, or when the paper comes into contact, the paper contact ruler 8 is easily shifted. As a result, there is a problem that the paper cannot be cut into a desired size. When the attraction force of the magnet is increased in order to solve this problem, the paper ruler 8 is strongly attracted to the paper table 1, so that the displacement of the positioned paper ruler 8 is eliminated. A new problem arises, such as difficulty in fine adjustment when fixing the ruler 8 at a predetermined position.

Next, in the case of using the screw mechanism, it is easy to adjust the paper contact ruler 8 to a desired position, and
There is no problem in that the paper ruler 8 is securely fixed to the guide ruler 7 and does not shift. However, during repeated positioning, the guide ruler 7 has a screw trace,
The part may be damaged gradually. As described above, when the surface of the guide ruler 7 on which the screw hits is damaged, the tip of the screw that has been tightened is guided by the damaged portion and moves. In some cases, the alignment may not be possible, and if the degree of damage is large, the fixing strength of the paper ruler 8 may be reduced. 8 is shifted.

[0007] In any of the devices using the magnet and the screw mechanism, the positioning of the paper contact ruler 8 is performed by visually measuring the paper contact ruler 8 on the ruled line written on the paper board 1. As a result, the position of the paper ruler 8 slightly changes. Also, since there is some gap (so-called play) in the fitting between the guide ruler 7 and the paper ruler 8,
An error may occur in the parallelism between the rail 2 and the paper ruler. Therefore, for example, after positioning the paper ruler 8 and cutting the paper to the size of the standard paper B5, the position of the paper ruler 8 is adjusted, then the paper is cut to the A4 size, and the paper ruler 8 is moved. In the case where the paper is cut to the size of B5, if there is a small deviation in the positioning of the paper ruler 8 and an error in the parallelism as described above, the paper of the size B5 which has been cut first and the paper which has been cut later are cut. There is a problem that irregularity occurs with the B5 size.

Therefore, according to the present invention, the work of positioning the paper ruler can be easily performed, the paper ruler can be securely fixed on the paper table, and the positioning of the paper ruler does not vary. An object of the present invention is to provide a positioning structure for a paper ruler.
