Abstract

PURPOSE:To obtain an automatic paper cutting machine capable of cutting recorded paper neatly by attaching a rotary blade to a pen block provided on a recording device and making possible the movement of the rotary blade, and the engagement and disengagement between the rotary blade and recording paper in the pen block. CONSTITUTION:If a pen block 2 approaches a side plate 11, the first support member 6a engages with a cam engagement roller 12. If the pen block further approaches the side plate 11, the engagement section of the cam engagement roller 12 moves along the cam surface formed on the external periphery of the first support member 61, while the cam engagement roller 12 and the first support member 61 maintains their engagement status. Since the position of the cam engagement roller 12 does not change, a rotating shaft to which the first support member 61 is fixed rotates, and a rotary blade 7 fixed to the rotating shaft moves to a position where the rotary blade comes in contact with recording paper 3 to cut the recording paper.

Description

[Detailed Description of the Invention] [Industrial Application] This invention relates to an automatic paper cutter 1t and Ir machine for a recording device.

[Conventional technology]

A conventional automatic cutting machine that cuts off the recorded paper in several layers (7) using a roll of recording paper and cutting this recording paper in a direction perpendicular to the direction of the moving force of the recording pen: There was one way.

The first method includes a fixed blade that is fixed across the width of the recording paper and a rotary cutter that cuts the paper by engaging the cutting edge of the fixed blade (for example, Utility Model No. 58-171358). issue).

Also, the second method is the dog horn method that is related to the present invention, but it differs from the first method described in L in that the cutting blade extends twice in the width direction of the recording paper. 81 Rotate in the -81 roller direction (direction perpendicular to the Zunaji cutting direction l) to the feeding direction of the paper 1. Instead of the toe-4 rie cutter that cuts the paper, a disc-shaped cutter is used. The rotary blade is configured to be movable in the cutting direction, and is rotatable in the direction of cutting IVr, which is the direction of cutting the recording paper by 7 degrees with respect to the shear direction t of the recording paper.

1 Suitable as a paper cutting machine, the structure is suitable for cutting paper by moving the rotary blade along the cutting line c while rotating the rotary blade, ``ζ cutting'' 4) The structure is also suitable for engraving, but the paper width - Cup c3 = Providing a special structure for the rotary blade to move the rotary blade and a structure to attach and detach the rotary blade from the recording paper changes the overall structure of the recording device from the old 1. I end up doing this.

C-Problems to be Solved by the Invention] Heretofore, there have been suitable automatic paper cutting machines for recording devices.

This invention was made in order to solve the problems mentioned in 1 of 642 and 3 of the prior art.By simply adding a simple structure, this invention is an automatic paper cutting machine that can cut recorded paper beautifully. The purpose is to provide

[Means to solve the problem]

In this invention, a rotary blade is attached to the bump 1' dock provided in this type of recording device c, and the movement of the rotary blade and the engagement and disengagement of the rotary blade with recording paper are provided within the pen block. It is now executed according to the structure.

[Effect]

The pen block can be moved freely in the Y-axis direction for recording. G3 dirt 6. m, l: It is possible to move the rotary blade automatically, and the main part of the structure that moves the recording pen up and down can be used to engage and disengage the rotary blade. The structure added for cutting becomes simple.
