Abstract

PURPOSE:To automatically cut off paper of a desired size for a desired sheet number with high size precision by designating the paper supply length and the cut-off sheet number and cutting off the paper with the designated supply length by the designated sheet number and discharging the cut-off paper. CONSTITUTION:When a paper size is designated, a platen roller 3 and a discharge roller 6 are reversed, the paper in the discharge path is driven backward and when the tip of the paper is detected by a 2nd sensor S2, the feeding is stopped. A rotary encoder 8 starts measuring the number of revolutions of the roller, that is, the paper feed quantity from this state and the platen roller 3 and the discharge roller 6 are both driven forward. When it is detected that the feeding of the paper by the designated feed length is finished, the platen roller 3 and the discharge roller 6 are stopped, the paper is cut off by a cutter 5 and the cut paper is discharged by the discharge roller 6. Thus, the paper of a desired size for a desired number of sheets is automatically cut off with high size precision.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a facsimile machine that uses thermal roll paper as printing paper.

<Prior Art> The above-mentioned facsimile machine is equipped with a cutter for cutting paper, but this cutter is for cutting out paper of a predetermined size after the printing operation is completed, and furthermore,
It also trims and aligns the leading edge of paper after replacing roll paper or clearing a jam.

<Problems to be Solved by the Invention> Users who have both the facsimile machine described above and a word processor that uses thermal paper may want to use facsimile paper when the word processor runs out of paper.

Conventionally, in such cases, the thermal roll paper was removed from the facsimile machine and cut to the desired size by hand, but this was extremely troublesome, the paper size was not accurate, and paper jams occurred when used in a word processor. There was also the risk of causing such problems.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily obtain a required number of sheets of a desired size from thermal roll paper by effectively utilizing a sheet cutting means originally provided in a facsimile machine.

<Means for Solving the Problems> In order to achieve the above object, the present invention is configured as follows.

That is, the present invention provides a facsimile machine that stores print paper and thermal roll paper (7), and is equipped with a paper feed mechanism for feeding the paper, a cutter for cutting the paper, and a cutter drive mechanism for driving the cutter. A designating means for designating the length and the number of sheets to be cut out, and a control means for controlling the paper feeding mechanism and the cutter drive mechanism so as to cut out and discharge a designated number of sheets of paper having a designated feeding length. .

Function> According to the above configuration, by specifying the required length of paper and the required number of sheets and issuing a paper cutting command, the required number of sheets of the desired length can be automatically cut out from the thermal roll paper. It will be done.

<Example> Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a schematic configuration of the main parts of a facsimile apparatus according to the present invention.

In the figure, ■ is a heat-sensitive roll paper, and the paper fed out from this passes through a curl correction plate 2 and then passes through a platen roller 3.
The paper is supplied between the printer and the thermal print head 4, and is then guided through a cutter 5 to a discharge roller 6, and is discharged onto a paper tray 7 provided outside the cabinet. Note that a first sensor S and a second sensor S for detecting the paper are provided in the paper path, and the rotation amount of the platen roller 3 is measured by a rotary encoder 8.

FIG. 2 schematically shows a control mechanism for cutting paper of a desired length from the thermal roll paper l.

In the figure, reference numeral 9 denotes a tanu operation section for specifying the paper feed length and the number of sheets to be cut out, which includes 10 groups of paper size specification keys, a numeric keypad 11 for specifying the number of sheets, a digital display section 12 for the number of sheets to be cut out, and a start key. 13 are provided.

Reference numeral 14 denotes a control circuit into which information from the operation section 9, the first sensor S0, the second sensor S, and the rotary encoder 8 is input, and a command from this circuit is sent to the drive circuit 15 to drive the platen roller. The motor M1 for driving the discharge roller is controlled via the drive circuit 16, and the operation of the tray 18 for driving the cutter is controlled via the drive circuit 17.

Next, the operation of paper cutout control will be explained based on the flowchart of FIG. 3.

When the start key 13 is turned on, it is confirmed whether the paper feed length, that is, the paper size is specified, and if no specification is made, the lamp 19 flashes to prompt the user to specify it. Note that if you press the start key 13 without specifying the number of sheets, cutting out only one sheet will be specified, and the digital display section 12 will display the
is displayed.

(Steps #1 to #3) When the confirmation of the paper size specification is completed, the platen roller 3 and ejection roller 6 are reversed, the paper in the ejection path is temporarily retreated, and the leading edge of the paper is detected by the second sensor S. Once this is done, the reverse transfer is stopped. (Steps #4 to #6
).

Next, from the state in which the platen roller 3 is stopped, the rotary encoder 8 starts measuring the amount of roller rotation, that is, the amount of paper feed, and both the platen roller 3 and the discharge roller 6 are driven to rotate in the normal direction. (Steps #7 and #8) Then, when it is detected from the measurement result of the row reencoder 8 that the specified feed length has been completed, both the platen roller 3 and the discharge roller 6 are stopped.Step #9 ．． #1
0), the cutter 5 is then driven to cut the paper, and only the ejection roller 6 is rotated normally to eject the cut paper.

At this time, the number of cuts is counted, and the remaining number is displayed on the digital display section 12. (Steps #11 to #14
) If there is a remaining number of sheets, the above operation is repeated, and if the count goes up, the state returns to the reset state.

(Step #15) <Effects of the Invention> As explained above, according to the present invention, the desired size can be easily and quickly cut with high dimensional accuracy without taking out the stored thermal roll paper and cutting it manually. It is possible to automatically cut out and take out a desired number of sheets of paper of the same size, thereby providing a practically convenient facsimile machine.
