Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll paper cutter for the Fakusumi River.

A roll paper cutter for facsimile machines as shown in FIG. 1 is known.

In Figure 1, reference numeral 1 indicates the roll paper, reference numeral 2 indicates a holding roller that holds the roll paper, reference numeral 3 indicates a decurling roller that straightens the curl of the roll paper 1, and reference numerals 4 and 5 rotate in the direction of the arrow. 6 is a print head, that is, a plotter that applies a voltage corresponding to the image to the roll paper 1 to form an electrostatic latent image, and 7 is an electrode provided opposite the plotter 6. 8 represents a roller, 8a represents a fixed blade of the roll paper cutter 8, and 8b represents a rotating blade of the roll paper cutter 8. The rotary blade 8b of the roll paper cutter 8 rotates in the direction of arrow a, and the fixed blade 8a
The roll paper 1 is cut when the rotary blade 8b comes into contact with the rotary blade 8b. In the paper cutter 8 shown in FIG.
Since the distance A from the recording part of block 16 to the cutting part of roll paper 1 cannot be shortened due to the presence of a fixed blade, it takes a long time to record on the roll vapor with plotter 6 and to cut the roll vapor. This method has disadvantages in that it takes a long time to make a copy after reception is completed, and there are many blank spaces at the leading edge of the paper. roll paper 1
In order to shorten the time from recording in block 6 to cutting the roll paper 1, there is a device that feeds the roll paper at high speed and scrapes it, but it has the disadvantage of being expensive. It is an object of the present invention to provide a roll paper that reduces the time required from recording on a roll paper with a plotter to cutting the roll paper, has fewer blank areas at the leading edge of the paper, and has less impact on the plotter when cutting the roll paper. Our goal is to provide cutters. The present invention will be explained below based on the embodiments shown in FIGS. 2 and 3.

In FIG. 2, reference numeral 1 indicates the roll paper, reference numeral 2 indicates the holding roller holding the roll paper, and reference numeral 3 indicates the holding roller holding the roll paper.
is a decal ring that corrects curls on roll paper.

4 and 5 are transport rollers rotated in the direction of the arrow, 6 is a block 1 which applies a voltage according to the image to the roll vapor to form a static latent image, and 7 is the plotter mentioned above. Electrode rollers provided opposite to 6 are shown, respectively. of the present invention. The vapor cutter 9 consists of a fixed blade 9a provided on the back of the stylus board of the blotter 6, and a rotary blade 9b that reciprocates along the fixed blade 9a. The fixed blade 9a is.
- Slightly longer than the width of Le Paper 1. The above rotary blade gb is
It is rotatably supported on a movable table 9c. The above moving table 9
c is a guide shaft 9d provided parallel to the fixed blade 9a;
It is movably supported at 9d. The moving table 9c moves integrally with a belt 9e attached to a pulley provided on the rotating shaft of a forward/reverse rotation motor (not shown) and a guide pulley provided opposite the pulley. It is attached to belt 9e. That is, the moving table 9c
is directly fixed to one end of the belt 9e and connected to the end of the belt 9e via a spring 9f. Due to the rotation of the pulley provided on the rotating shaft of the forward/reverse rotation motor, the movable table 9c is reciprocated along the fixed blade 9a in the direction of arrow b, and as the movable table 9c moves, the rotary blade 9b comes into contact with the fixed blade 9a. It moves back and forth while doing so. In the case of continuous reception, it is also possible to separate the rotary blade from the fixed blade by using a return ladder or the like. The rotary blade 9b
is rotated by the frictional force when moving while contacting the fixed blade ga, and when moving in one direction, the fixed blade g
Cut the roll paper 1 located between a. In the roll vapor cutter 9 of the present invention, since the fixed blade ga is provided on the back of the stylus board of the blotter 6, the distance B between the cutting part of the roll paper 1 and the recording part of the plotter 6 is very short. ``The time from recording on roll paper I with plotter 6 to cutting roll vapor 1 is short, and there is less blank space at the tip of the paper.
Moreover, since the roll paper is held between the electrode rollers facing the plotter 6, it is possible to prevent the tip of the roll paper from sagging due to the cutting force generated during cutting, and the rotary blade 9b Since the plotter 6 reciprocates, there is an effect that there is less impact on the plotter 6 when cutting the roll vapor.
