JPH01146688A - Cutter for roll recording paper - Google Patents

Abstract

PURPOSE: To continuously cut the rolled recording paper and to perforate the rolled recording paper by selectively setting a movable blade at a first set position, where both of an outside and an inside blade of a rotary blade are meshed with a fixed blade, and a second set position, where the only outside blade is meshed with the fixed blade, in relation to the fixed blade. CONSTITUTION: In the case of receiving one piece per each one communication, both blades 7a, 7b of outside and inside of a rotary blade 7 are meshed with a fixed blade 6, and the rotary blade 7 is moved along the fixed blade 6 with the self-rotation of the rotary blade 7 so as to continuously cut a rolled recording paper 1 received after recording. Continuously, in the case of receiving plural pieces per each one communication, the center of rotation of the rotary blade 7 is moved to a direction for separating from the fixed blade 6, and the only outside cutting blade 7a of the rotary blade 7 is meshed with the fixed blade 6, and the received recording paper 1 is perforated between each page by the outside cutting blade 7a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting device for roll recording paper in facsimile machines and the like.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 53-54409, the conventional cutting device for roll recording paper in facsimile machines, etc. uses a cutter consisting of a fixed blade and a rotating blade to cut the roll recording paper that has passed through the recording unit into one original to be sent. It was only equipped with a continuous cutting function.

[Problem that the invention seeks to solve]

The cutting device according to the above-mentioned conventional technology can only continuously cut the roll recording paper in units of one document to be sent.
When receiving multiple sheets at the same communication rate, it is not possible to prevent the pages of the reception record sheet from being disturbed or scattered, resulting in a lack of fine-grained service for customers. To prevent dissipation, it is an object of the present invention to provide a cutting device for roll recording paper that can not only cut continuously but also cut perforations between pages.

[Means for solving problems]

The above object is to provide a roll recording paper cutting device in which a cutter section is composed of a fixed blade and a rotary blade that rotates and moves along the fixed blade. The rotary blades are arranged alternately in the circumferential direction, and the set position of the rotary blade relative to the fixed blade is set to a first set position where both the outer and inner cutting blades engage with the fixed blade, and a first set position where only the outer cutting blade is fixed. This is achieved by having a configuration that can be switched to a second set position in which the blade engages.

[Effect]

In response to signals from the control unit, the rotary blade moves along the fixed blade while rotating, and the engagement between the rotary blade and the fixed blade is changed to continuously cut the roll recording paper or make perforations. Therefore, the rotary blade is set to either the first or second set position and operated. Thereby, for example 1
If one sheet is received at the communication rate, continuous cutting is performed using both the outer and inner cutting blades of the rotary blade, and if multiple sheets are received at one communication rate, the page and page of the reception record paper are cut. In between, it becomes possible to make perforations using only the outer cutting edge of the rotary blade. However, even when receiving multiple sheets, the customer can freely select whether to cut them continuously or to add perforations. [Example] Hereinafter, an example of the present invention is shown in Fig. 1. This will be explained with reference to FIG.

Figure 1 shows the facsimile roll recording paper being received and recorded.
A layout diagram of the parts to be cut, including a roll recording paper 1, a recording paper guide 2, a thermal recording head 3, a head roller 4, cutter guides 5a and 5b, a fixed cutter blade 6, and a rotary blade 7.
are arranged as shown in the figure, and the roll recording paper 1, which has been received and recorded by the thermal recording head 3 and the spacing roller 4, is moved to the cutter guide 5a.

5blC is guided to the ivy section and cut using the fixed cutter blade 6 and the rotary blade 7). This cutting is performed by moving a disc-shaped rotary blade 7 laterally in the recording paper width direction along a rectangular fixed blade 6, and rotating the rotary blade 7 due to friction with the fixed blade 6. In the present invention, By shifting the center of rotation of the rotary blade 7 up and down to change the engagement between the fixed blade 6 and the rotary blade 7, in addition to the function of the conventional device that only continuously cuts one document to be sent, it is possible to cut the original perforation by one perforation. It was also possible to enter

FIG. 2 is a detailed view of the rotary blade 7. On the circumference of the rotary blade 70, two stages of cutting blades 7a and 7b, outer and inner, are provided alternately in the circumferential direction. Both the outer and inner cutting blades 7a and 7b are used for making perforations, and only the outer cutting blade 7a is used for making perforations. The perforation dimensions are cutting edge 7.
It can be freely selected by changing the width dimensions of a and 7b. Figure 3 is a side view of the cutter section, showing the state when the rotary blade 7 is cutting continuously. At this time, the cutting blade 7
The movable table 150 supporting the guide shaft 9 compresses the spring 8a,

4b, the rotary blade 7 is set at a lower fixed position (first set position). Then, by receiving power from the left and right gears 10a and 10b via the timing belt 11 and moving in the left-right direction while rotating, both the apocryphal and inner cutting blades 7 of the rotary blade 7 shown in FIG.
a, 7b mesh with the fixed blade 6 to continuously cut the roll recording paper 1; zero set position switching lenses 12a, 12;

When the rotary blade 7 is pushed up to the position where it contacts the upper part and set in the upper fixed position (second set position [ ), the rotary blade 7 rotates on its own axis and moves in the left and right direction, causing the rotation shown in Fig. 2. Only the outer cutting edge 7a of the blade 7 engages with the fixed blade 6, making it possible to make perforations in the roll recording paper 1.

Figure 4 shows the signal processing procedure in a conventional facsimile machine.Whether receiving one sheet or multiple sheets at one communication rate, software is used to continuously cut the roll of recording paper in the post-procedure and middle-procedure. It was configured.

FIG. 5 is a control block diagram showing an example of signal control to the cutter section in the present invention.
Distinguish between sheet reception and multiple sheet reception, and in the post-procedure in the case of single sheet reception, execute the process of continuous cutting control 17,
A continuous cutting operation signal is output to the cutter section 20. In addition, in the case of receiving multiple sheets, the number of originals to be sent is preset to the counter +8, and the counter 18 counts each time the image signal processing for one sheet is completed. Perforation control by signal 19
The process of continuous cutting control 17 is executed (by the signal from the counter 18) in the post-procedure following the final image signal processing, and the process of continuous cutting control 17 is executed. This is an example in which a continuous cutting operation signal is output to the cutter unit 20.

However, at the customer's discretion, the perforation control in the middle procedure when receiving multiple sheets can be changed to continuous cutting control.

〔Effect of the invention〕

According to the present invention, in addition to the function of continuously cutting the received and recorded roll recording paper, it is also possible to make perforations.
As a result, when receiving multiple sheets, it is possible to prevent the pages of the reception record paper from being disturbed or scattered, making it possible to provide detailed service to customers.
