DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus and a recording method for reciprocating a recording head in a main scanning direction and conveying a recording sheet in a sub-scanning direction to record on the recording sheet.

[0002]

2. Description of the Related Art In a recording apparatus capable of recording on a long recording paper such as a roll paper in which a long strip of recording paper is wound in a roll shape, the fed long recording paper is conveyed in a sub-scanning direction. Then, ink is ejected from the head surface of the recording head that reciprocates in the main scanning direction, and recording is performed. After the recording is performed, the long recording paper is cut by a cutter provided on the downstream side in the sub-scanning direction from the recording means by the recording head, and is discharged as cut paper.

In such a recording apparatus, for example, a plurality of recordings are continuously performed on recording on roll paper, and the recording is cut at a boundary between the recordings by a cutter provided downstream of the recording means in the sub-scanning direction. The sheet is discharged as a cut sheet for each record. At this time, it is difficult to precisely match the cut position of the rolled paper after recording with the cutting position by the cutter because there is a limit in the recording paper conveyance accuracy. By shifting the position actually cut by the cutter, the margin at the beginning of the next recording is affected, and the width of the margin cut by the cutter among the margins provided with a predetermined width on the four sides of the recording is changed. However, there is a problem that the width may be slightly larger or smaller than a predetermined width. That is, since it is difficult to accurately match the intermediate position between the end position of one recording on the roll paper and the start position of the succeeding recording to the cutting position of the cutter, the width of the margin is slightly widened or narrowed. There has been a problem that there is a possibility that it will be lost.

[0004] In addition, especially when recording is performed without margins on the entire upper and lower ends or the upper, lower, left and right ends, the end position of one recording is determined.
If a series of recordings is performed without a margin between the start position of the next recording and the boundary, and the boundary is cut with a cutter, it is practically possible to accurately cut the boundary between the recordings without the margin. Is almost impossible. In other words, if cutting is performed at a position slightly deviated from the boundary between the recordings having no blank space, the recording on one side always includes a part of the recording on the other side. That is, if the roll paper is cut at a position shifted from the position to be cut after the recording, a part of the recording near the start end or near the end of the recording may be cut while being included in the adjacent recording. become.

For this reason, in the conventional recording apparatus, even when printing is performed without blanks on the entire upper and lower ends or the entire upper, lower, left and right ends, a certain amount of margin is provided between the recordings, and the margin is slightly smaller than the final cutting position. Recording in a wide recording area. Then, a position slightly outside the both ends of the margin, that is, a position slightly entering the recording area side from the end position of the recording,
The roll paper is cut twice each at a position slightly closer to the recording area than the start position of the subsequent recording. This is because the paper is cut at a position slightly in the recording area from the start or end position of the recording, and a part of the starting or end of the recording area is cut off together with the blank roll paper, so that the error in the accuracy of recording paper conveyance is obtained. The difference between the position at which the recording paper is cut by the cutter and the position at which the roll paper should be cut is absorbed. The reason for providing a blank space between adjacent recordings is that when cutting is performed near the end position of the previous recording (in the recording area), and when cutting is performed near the starting end position of the subsequent recording (in the recording area). This is because it is difficult to perform stable cutting if there is no roll paper of a certain width or more at the cutting position. This prevents a part of the recording near the start end or near the end of the recording from being cut while being included in the adjacent recording when recording is performed on the roll paper without any blank space.

[0006]

First, in the case of recording with margins, it is difficult to cut accurately at the middle position of the margin provided between the recordings as described above. There has been a problem that the width of the margin varies and it is difficult to make it uniform. Further, when performing recording without margins, as described above, recording is performed with a certain amount of margin provided at the boundary between the recordings, and at the boundary between the recordings, the vicinity of the end position of the recording (in the recording area) and the next Performing a total of two cuts near the recording start position (in the print area) as described above increases the number of cuts and lowers the throughput of printing, and at the same time discards the blank recording paper. However, there is a problem that the recording paper is wasted.

Further, after recording, the roll paper is cut by a cutter provided downstream of the recording means in the sub-scanning direction and discharged as cut paper. In preparation for the next recording, it is necessary to reversely feed the roll paper until the start end of the roll paper is located on the upstream side of the recording means, thereby causing a problem that the throughput of recording execution is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation, and a problem thereof is to reduce variations in the margin width at the upper and lower ends of recording when performing recording with margins on long recording paper. In addition, when performing recording on a long recording paper without margins, there is a need to eliminate recording paper that is wasted. Another object of the present invention is to improve the throughput when recording on a long recording sheet.

[0009]

According to a first aspect of the present invention, there is provided a recording sheet conveying means for conveying a recording sheet in a sub-scanning direction, and reciprocating in a main scanning direction. A recording apparatus includes a recording unit that records on recording paper, and a recording paper cutting unit that is disposed upstream of the position of the recording unit in the sub-scanning direction.

As described above, by providing the recording paper cutting means on the upstream side in the sub-scanning direction with respect to the recording means, when recording on a long recording paper, a long recording paper is required before one recording is completed. When the position where the paper is to be cut is conveyed to the cutting position of the recording paper cutting means, the long recording paper can be cut. Then, in the middle of the recording, the long recording paper is cut at the position to be cut, and thereafter, the recording is continued in the form of the cut sheet, so that the recording is normally performed by the paper detector provided on the upstream side of the recording means. In addition, it is possible to detect the end position of the recording paper, and it is possible to execute the recording that determines the end of the recording area in accordance with the detected position, thereby making it possible to perform recording with little variation in the margin width of the end of the recording paper. It becomes possible.
Then, the subsequent recording on a long recording sheet can be started in a state where the starting end position of the recording sheet is accurately detected by the paper detector, so that the recording with little variation in the margin width of the starting end of the recording sheet can be performed. It becomes possible.

Therefore, the position of the recording paper that is actually cut by the recording paper cutting means is displaced from the position where the recording paper is to be cut. There is no possibility that the width of the margin of the side cut by the recording paper cutting means among the margins provided by (1) is slightly larger or smaller than the predetermined width.

Further, since the recording paper cutting means is disposed upstream of the recording means in the sub-scanning direction, the rolled paper after cutting (the remaining portion excluding the portion cut into cut paper by cutting) ) Is located upstream of the recording means in the sub-scanning direction, and is not located downstream of the recording means in the sub-scanning direction. There is no need to return to the upstream position. Therefore, since it is not necessary to reversely feed the recording paper, it is possible to improve the throughput of recording execution.

Thus, according to the recording apparatus of the first aspect of the present invention, when performing recording with a margin on a long recording sheet, variation in the margin width at the upper end and the lower end of the recording is reduced. In addition to this, it is possible to improve the throughput when recording on a long recording paper.

When the cut paper Pa is discharged, the roll paper P (the remaining roll paper P excluding the cut paper Pa by cutting) is automatically fed. When the recording is executed, since the roll paper P is automatically fed in advance, the recording can be started immediately.
Thereby, the throughput of recording execution is further improved.

Since the position of the roll paper P to be cut during recording is calculated from the recording data, it is possible to determine the end of the cut paper Pa based on the calculated position. At this time, although there is a possibility that the margin width at the end of the cut sheet Pa may slightly fluctuate, the cut sheet Pa detected by the paper detector 24 may be used.
, It is possible to omit the step of determining the end of the cut sheet Pa based on the end detection signal.

As another embodiment, the present invention can be applied to a recording apparatus 50 having no automatic sheet feeding apparatus, and the same applies to a recording apparatus 50 dedicated to roll paper. . FIG. 9 is a schematic side view showing an embodiment of the present invention in a recording apparatus 50 exclusively for roll paper having no ASF.

Since there is no ASF and no paper feed roller, the roll paper cutting device 1 and the paper detector 24 are provided between the transport drive roller 53 and the paper discharge drive roller 55 on the upstream side of the recording head 62. Have been. Other configurations are the same as those in FIG.

The roll paper P is manually fed to a position where the leading end thereof can be transported by being sandwiched between the transport driving roller 53 and the transport driven roller 54. The roll paper P is
The ink is ejected from the recording head 62 mounted on the carriage 61 while the carriage 61 is reciprocated in the main scanning direction X, and is transported between the transport drive roller 53, the transport driven roller 54, and the discharge port. The paper is driven intermittently in the sub-scanning direction Y by the paper drive roller 55 and the paper discharge driven roller 56 to perform recording.

Before the roll paper P is cut, the discharge driving roller 55 and the discharge driven roller 56 disposed downstream of the recording head 62 in the sub-scanning direction Y are in a free state, The roll paper P is transported by the transport roller 53 and the transport driven roller 54 (first recording paper transport control mode).

Subsequently, the roll paper P during the recording is cut by the recording paper cutting device 1 disposed between the transport driving roller 53 and the recording head 62 (recording paper cutting control mode). At this time, the roll paper P is transported upstream of the recording head 62 by a transport driving roller 53 and a transport driven roller 54.
At the downstream side of the recording head 62, the sheet is nipped and cut by the sheet discharge drive roller 55 and the sheet discharge driven roller 56.

After the roll paper P has been cut, the transport drive roller 53 and the transport driven roller 54 hold the cut roll paper P (the remaining portion excluding the cut portion) and hold the cut roll paper P. The rolled paper P is conveyed by a discharge drive roller 55 and a discharge driven roller 56 (second recording paper conveyance control mode).

As described above, the starting end of the cut roll paper P (the remaining roll paper P excluding the portion that has become cut paper Pa by cutting) is held between the transport driving roller 53 and the transport driven roller 54. In this state, it is held at a position immediately upstream of the recording head 62. Therefore, at the time of the next recording execution, the recording can be started immediately, and the paper feeding operation is not required, so that the throughput of the recording execution is improved.

In this way, without an automatic paper feeder,
In the recording apparatus without the paper feed roller 22, the roll paper cutting device 1 is disposed between the transport driving roller 53 and the paper discharge driving roller 55 on the upstream side of the recording head 62, so that the present invention can be implemented. It is possible, and the operation and effect of the present invention can be obtained.

Further, as another embodiment, there is provided an apparatus in which a well-known borderless recording means (not shown) for performing recording with no margin on roll paper is provided in the recording apparatus 50 of the above-described embodiment. . According to the present invention, a particularly great effect can be obtained in such a recording apparatus. Hereinafter, description will be made with reference to FIGS.

As shown in FIG. 3, first, the start end of the roll paper P rotatably supported by the roll paper holder 21 is manually set by the paper feed roller 22 to a position where the paper can be automatically fed. Then, the paper feed roller 22 is controlled by the automatic paper feed control.
Rotates, and the roll paper P is fed.

Subsequently, as shown in FIG. 4, the starting end of the fed roll paper P is detected by the paper detector 24.
It is sandwiched between the transport driving roller 53 and the transport driven roller 54, and is transported in the sub-scanning direction Y by the rotational driving force of the transport driving roller 53.

The roll paper P transported between the recording head 62 and the platen 52 is ejected with ink from the recording head 62 mounted on the carriage 61 while reciprocating the carriage 61 in the main scanning direction X, and is transported. The paper is intermittently conveyed in the sub-scanning direction Y by the roller 53 and the conveyance driven roller 54, and the marginless recording is performed slightly before the start end of the roll paper P. At this point, the roll paper P has not been cut yet, and recording is performed as a series of roll paper.

Subsequently, as shown in FIGS. 5 and 6, when the position where the roll paper P is to be cut during recording is transported to the cutting position of the roll paper cutting device 1, the roll paper P is
At the position where the roll paper P is to be cut, the roll paper cutting device 1
, And the cut portion of the roll paper P becomes cut paper Pa.

Further, as shown in FIG. 7, borderless recording is continuously performed on the cut sheet Pa cut by the roll paper cutting device 1 during recording. When the end of the cut sheet Pa passes through the paper detector 24, the paper detector 24
Is self-returned to the standing position, and the end of the cut sheet Pa is detected.

Then, as shown in FIG.
After the marginless printing is performed to a position slightly beyond the end of the paper, the paper is discharged by the paper discharge drive roller 55 and the paper discharge driven roller 56. In addition, the paper feed roller 22 is a roll paper P
The roll paper P is stopped at such a position as to keep the state of sandwiching the vicinity of the start end of the remaining roll paper P (excluding the portion that has become cut paper Pa by cutting), and the roll paper P is automatically fed at any time from this state. It is possible.

As described above, before the recording is completed, the roll paper P is cut when the cutting position of the roll paper P is conveyed to the cutting position of the recording paper cutting means. By performing marginless recording to a position slightly beyond the end of the roll paper P, even if the cut position of the roll paper P is shifted from the position to be cut due to the transport error of the roll paper P,
It is possible to perform borderless recording without margins up to the end of cut paper Pa after cutting.

As a result, when marginless recording is performed on the roll paper P, the number of cuts between recordings is only one, and it is necessary to perform recording with a certain space between recordings as in the related art. And 2 in the margin of the roll paper P after recording.
No need to cut twice. Accordingly, it is possible to eliminate the blank roll paper P which is wasted and discarded, and it is possible to improve the throughput of recording execution because the number of cuts of the roll paper P between recordings is only one. Become. Further, since the roll paper P is cut between the transport drive roller 53 and the paper discharge drive roller 55, it is not necessary to reversely feed the cut roll paper P during the next recording. Marginless recording throughput is improved.

As described above, the present invention is particularly advantageous in marginless printing, in which printing is performed on roll paper without margins, so that wasteful recording paper can be eliminated and the throughput can be greatly improved. Is possible.

Further, the present invention can be implemented in a recording apparatus that performs recording on a long recording paper other than the roll paper as shown in the above embodiment, and the present invention is limited to the above embodiment. Without departing from the scope of the invention described in the claims, various modifications are possible, and it is needless to say that they are also included in the scope of the invention of the present application.
