Description

The present invention relates to an automatic paper cutting machine for a recording apparatus.

[Conventional technology]

There are two conventional methods as an automatic cutting machine for cutting off recorded paper by using a roll wrapping paper as a recording paper and attaching the recording paper to a recording device for feeding the recording paper in a direction perpendicular to the moving direction of the recording pen. It was

The first method is to have a fixed blade fixed across the width of the recording paper and a rotary cutter that engages the cutting edge of the fixed blade to cut the paper (for example, Japanese Utility Model Laid-Open No. 58-171358). issue).

Another method is a large method related to the present invention, but the difference from the first method is that it extends as a cutting blade in the width direction of the recording paper and coincides with the feeding direction of the recording paper. Rotate in the direction (that is, the direction orthogonal to the cutting direction) to replace the rotary cutter that cuts the paper,
A rotary blade, which is disk-shaped and rotatable in a direction transverse to the feeding direction of the recording paper, that is, in the cutting direction, is configured to be movable in the cutting direction.

The most suitable structure for a paper cutting machine is to move the rotary blade along the cutting line while rotating the rotary blade to cut, but record the structure and the rotary blade that move the rotary blade to the full width of the paper. Specially providing a structure for engaging and disengaging the paper for the rotary blade complicates the structure of the entire recording apparatus.

[Problems to be solved by the invention]

As described above, conventionally, there has been no suitable automatic paper cutting machine for a recording apparatus.

The present invention has been made to solve the above-mentioned problems in the conventional art, and an object of the present invention is to provide an automatic paper cutting machine capable of beautifully cutting recorded paper by simply adding a simple structure. To aim.

[Means for solving the problem]

In the present invention, the rotary blade is attached to the pen block provided in this type of recording apparatus, and the movement of the rotary blade and the engagement and disengagement of the rotary blade and the recording paper are executed by the structure provided in the pen block. I did it.

[Action]

Since the pen block can move freely in the Y-axis direction for recording, this allows the rotary blade to move automatically, and the main part of the structure that moves the recording pen up and down is used to engage the rotary blade. Since you can leave with
The structure to be added for cutting the paper becomes simple.
