Description

[Detailed Description of the Invention] The present invention relates to a recording device that records on a long recording medium.

In general, this type of recording device has different timings when cutting a long recording medium to the required length, such as an after-cut method in which the recording medium is cut after recording, and an after-cut method in which the recording medium is cut before recording. There are two main types of methods: a pre-cut method in which the recording medium is cut, and a method in which the recording medium is cut during recording.

However, in the after-cut method, after recording, it is necessary to transport the recording medium in the opposite direction to that during recording, and the recording medium conveying means must have a reversing function, and the recording speed cannot be increased. Indeed, there was a disadvantage that a higher recording speed was disadvantageous because the proportion of time required to cut the recording medium increased.

On the other hand, in the pre-cut method, in order to ensure a certain cutting length or more, it is necessary to increase the conveyance distance of the recording medium from the cutting section to the recording section, which makes the device larger and more complicated, and the paper The drawback was that it was more likely to get clogged.

In addition, in the method of cutting the recording medium while recording, when the recording medium is cut, the recording medium on the recording unit side is pulled in the cutting direction, which not only affects recording but also If further development and fixing are to be carried out later, the recording medium will be developed and fixed at the time of cutting.
If it reaches the fixing section, it has the disadvantage that it can cause uneven development and uneven fixing.

The present invention has been made to solve the above-mentioned conventional drawbacks, and it is possible to cut the recording medium while recording without affecting recording, development, and fixing, simplify the recording medium conveyance means, and To provide a recording device which requires less time for cutting and can use a recording medium economically by reducing the margin of the recording medium.

An embodiment of the present invention will be explained below.

This embodiment shows an example in which the present invention is applied to a facsimile recording device.
is pulled out from the roll 1, passes through a roller 3, a paper feed roller 4, a cutting device 6 having a cutter 5, and a paper feed roller 7 in order, and is sent between a recording head 8 and a head presser roller 9, and is sent to the recording head 8. Recording is performed using the paper feed roller 10, a developing device 11, a fixing device 12, and a paper feed roller 13 before being sent to a stacker 14.

When the recording paper 2 passes through the cutting device 6 by a required length corresponding to the length of the document to be recorded while the recording head 8 is recording on the recording paper 2, The cutter 5 is automatically rotated to cut the recording paper 2.

Further, the driving rotation speed of the paper feed roller 4 is set higher than that of the paper feed roller 7, so that while both rollers 4 and 7 are being driven,
As shown in FIG. 2, the recording paper 2 is cut by a cutting device 6.
The sheet is conveyed with a bend between the sheet and the paper feed roller 7.

Further, when the cutting device 6 cuts the recording paper 2, the paper feed roller 4 temporarily stops rotating, and then the recording paper 2 on the recording head 8 side separated from the roll 1 side by the cutting is transferred. The recording paper 2 continues to be conveyed by the conveyance means after the paper feed roller 7, and rotation is restarted at the same time when the deflection of the recording paper 2 that occurred before the cutting is eliminated.

The operation of this device will be explained below.

When recording is started, the recording paper 2 is conveyed along the path with a bend between the cutting device 6 and the paper feed roller 7, but the recording paper 2
While recording on the recording paper 2, when the recording paper 2 passes through the cutting device 6 by the required length corresponding to the length of the document to be recorded, the cutting device 6 rotates the cutter 5. to cut the recording paper 2.

In this recording apparatus, during this cutting, the recording paper 2 is conveyed in a bent state between the cutting device 6 and the roller 7 in front of the recording head 8, so that the recording paper 2 is The recording paper 2 will not be pulled by the cutter 5.

Therefore, the recording on the recording paper 2 by the recording head 8 is not affected at all by the cutting, and at the time of the cutting, the recording paper 2 on the recording head 8 side
Even if a portion of the toner reaches the developing device 11 or the fixing device 12, the cutting will never cause uneven development or fixing.

Now, the recording paper 2 on the recording head 8 side separated from the roll 1 side by the above-mentioned cutting is transferred to the paper feed roller 7.
The paper continues to be transported by the subsequent transport means in the same manner as before the cutting, and the remaining recording is carried out in the recording head 8, developed and fixed in the developing device 11 and the fixing device 12, respectively, and finally, Stadka 14
It is transported to and stocked.

On the other hand, since the paper feed roller 4 temporarily stops rotating at the same time as the cutting, the conveyance of the recording paper 2 on the roll 1 side that remains after the cutting is temporarily stopped. Therefore, there is no problem in which the leading edge of the recording paper 2 on the roll 1 side catches up with the trailing edge of the recording paper 2 on the recording head 8 side and the two overlap.

Furthermore, as the conveyance of the recording paper 2 on the recording head 8 side progresses and the deflection of the recording paper 2 on the recording head 8 side that occurred before the cutting is eliminated, the rotation of the paper feed roller 4 is resumed. The recording paper 2 on the stopped roll 1 side is conveyed to the recording head 8,
Thereafter, recording, development, fixing, cutting, etc. are performed in the same manner as above.

Note that when restarting the conveyance of the recording paper 2 on the roll 1 side that has been temporarily stopped after cutting as described above, the paper feed rollers 4, 7 and The recording paper 2 on the roll 1 side may be rapidly fed to a predetermined position of the recording head 8 by rotating the head presser roller 9 rapidly.

Further, although the above embodiment is an example in which the present invention is applied to a facsimile machine, the present invention can be applied to a printer other than a facsimile machine as long as it records on a long recording medium and cuts this recording medium. Needless to say, the present invention can also be applied to heat-sensitive recording devices and other recording devices.

As described above, the recording device according to the present invention cuts a recording medium such as a recording paper during recording, and at least during the cutting, the recording medium is deflected at least between the cutting device and a recording section such as a recording head. (a) Unlike the after-cut method, there is no need to transport the recording medium in the opposite direction to that during recording after recording, so the recording medium conveying means There is no need to provide a reversing mechanism in the recording medium, and the mechanism of the conveying means can be simplified, and the proportion of time required to cut the recording medium does not increase as the recording speed increases.

(b) Unlike the pre-cut method, there is no need to increase the transport distance of the recording material from the cutting section to the recording section, so the device becomes larger and more complex, and the recording material is more likely to become clogged in the transportation path. There is no risk of it happening.

(c) Unlike conventional methods in which cutting is performed during recording, there is no risk of cutting affecting recording, development, fixing, etc.

(D) Since cutting is performed while recording,
Because the cutting length of the recording medium and the position of the recordable portion of the recording medium are not restricted by the positional relationship between the recording section and the cutting section, the margins of the recording medium can be reduced, making the recording medium economical. Can be used.

It has excellent effects such as.
