Description

  The present invention relates to a roll paper cutting control method for an ink jet recording apparatus having a configuration capable of recording on roll paper.

  As an ink jet recording apparatus capable of executing recording on roll paper, a recording execution means for executing recording on recording paper including roll paper, and roll paper disposed on the downstream side in the sub-scanning direction of the recording execution area by the recording execution means 2. Description of the Related Art An ink jet recording apparatus that includes a roll paper cutting unit such as a cutter and has a configuration capable of performing recording on roll paper and cutting the roll paper after execution of recording at an appropriate cutting position is known.

  In such an ink jet recording apparatus, recording execution control and roll paper cutting control that are generally performed in the past are first performed based on the recording paper size information included in the recording data and the recording area and recording on the roll paper. A cutting position near the end of the region is determined. Subsequently, recording is performed on the recording area of the roll paper by the recording execution means. Then, the paper is cut at a predetermined cutting position and discharged in the same manner as a cut sheet such as plain paper.

  When the roll paper after recording is cut near the end of the recording area, the roll paper is conveyed in the sub-scanning direction until the vicinity of the end of the recording area reaches a cutting position that can be cut by the roll paper cutter. Then, the roll paper is cut by a roll paper cutter. After cutting, the roll paper on the upstream side in the sub-scanning direction from the cutting position of the roll paper cutter is transported in the direction opposite to the sub-scanning direction until the starting edge reaches the recording start position of the recording execution means, and the next recording area Is recorded.

  Therefore, when continuously executing a plurality of recording areas, after each recording area has been recorded, the roll paper is transported in the sub-scanning direction, cut, and transported in the direction opposite to the sub-scanning direction. The recording of the next recording area is repeated. Therefore, this causes a problem that the throughput of recording execution decreases.

  As a conventional technique for solving such a problem, when a plurality of recording areas are continuously recorded, there is a recording area in which recording is performed next when recording is completed up to the end of one recording area. Is known in which the next recording area is directly executed without cutting the roll paper at that time. Since the roll paper cutting operation described above is not executed for each recording area, the throughput of recording execution can be improved.

  In addition, the cutting of the roll paper in the vicinity of the start end and the end of the recording area after the recording is performed is performed when the user presses an operation button for cutting and discharging the roll paper after all the recording ends. The paper is conveyed in the direction opposite to the sub-scanning direction, and the roll paper is cut and discharged by the roll paper cutter at all positions to be cut. Alternatively, it is possible to cut and discharge only the vicinity of the final end of the plurality of recording areas. Alternatively, while continuously performing recording in a plurality of recording areas, cutting is performed when the position to be cut between the recording areas reaches the cutting position of the roll paper cutter during recording, and only the last recording area is recorded by the user. Can be cut and discharged by a roll paper cutter by pressing the operation button.

By the way, in an ink jet recording apparatus having a configuration capable of executing recording on roll paper, generally, the roll paper before execution of recording remaining in the ink jet recording apparatus is on the roll paper holder side, that is, in the paper feeding direction. A roll paper discharge button for discharging in the direction opposite to the sub-scanning direction is provided. In the case of single-sheet paper, it can be discharged in the sub-scanning direction, but the roll paper is not rolled in the sub-scanning direction because a series of long recording paper is wound in a roll shape. It is conveyed and discharged in the opposite direction.

  However, when the above-mentioned operation button is pressed, if the recording-executed recording area that should be discharged in the sub-scanning direction remains on the roll paper, pressing this roll-paper discharge button has already executed the recording. In the state where the recording area remains, it is discharged to the roll paper holder side. As a result, there arises a problem that it becomes impossible to cut the vicinity of the start end and the vicinity of the end of the recorded recording area with a roll paper cutter.

  The present invention has been made in view of such a situation, and the problem is that the roll paper is discharged to the roll paper holder side in a state where the recording area where recording has been performed remains on the roll paper. It is to prevent the vicinity of the start end and the vicinity of the end of the recorded recording area from being cut by a roll paper cutter.

  In order to achieve the above object, the invention according to claim 1 of the present application relates to an operation of ejecting ink onto the recording paper while reciprocating the recording head in the main scanning direction, and intermittently conveying the recording paper in the sub-scanning direction. In the ink jet recording apparatus that executes recording on the recording paper by alternately repeating the operation to perform, when recording on roll paper, the vicinity of the start end of the recording area of the predetermined length in the sub-scanning direction on the roll paper and A roll paper cutting control method for cutting the roll paper in the vicinity of the end, wherein when the roll paper is discharged in a direction opposite to the sub-scanning direction, a recording area that has not been cut on the roll paper and has been executed If there is, the roll paper is cut in the vicinity of the start and end of the recording area where the recording has been performed, and then the roll paper is discharged in the direction opposite to the sub-scanning direction. A Lumpur paper cutting control method.

  Roll paper remaining in the ink jet recording apparatus with the recorded recording area remaining on the recording surface is cut by a roll paper cutter and discharged in the sub-scanning direction, regardless of whether it is automatic or manual. It should be. However, when a plurality of recording areas are continuously recorded on the roll paper, the roll paper is transported to the cutting position every time one recording area is recorded as described above from the viewpoint of throughput of recording execution. It can be said that it is wasteful to cut.

  Further, as described above, it can be said that cutting at a position to be cut after performing recording of a plurality of recording areas at once in one stroke is one method that does not reduce the throughput. Furthermore, there is a need to discharge the roll paper in a form that does not cut at the position where it should be cut, and the recording area recorded on the roll paper is not necessarily cut for each recording area. Therefore, it is assumed that there are many cases where the ink jet recording apparatus is in a recording standby state in a state in which the roll paper having a recorded recording area remains in the ink jet recording apparatus from the variations of the roll paper cutting control. I can say that.

  In the roll paper cutting control method according to the first aspect of the present invention, when there is a recording-executed recording area that is not cut on the roll paper, the roll-paper cutting control method is performed in the vicinity of the start and end of the recording area that has been recorded After the roll paper is cut, the roll paper is discharged to the roll paper holder side in the direction opposite to the sub-scanning direction. Can be discharged.

  Thus, according to the roll paper cutting control method according to the first aspect of the present invention, the roll paper is discharged to the roll paper holder side in a state where the recording area where recording has been performed remains on the roll paper. Therefore, it is possible to obtain an effect that it is possible to prevent the vicinity of the start end and the end end of the recorded recording area from being cut by the roll paper cutter.

  According to the second aspect of the present invention, the operation of ejecting ink onto the recording paper while reciprocating the recording head in the main scanning direction and the operation of intermittently conveying the recording paper in the sub-scanning direction are repeated alternately. In the ink jet recording apparatus that performs recording on the recording paper, when recording on the roll paper, the roll paper is positioned near the start and end of the predetermined length recording area in the sub-scanning direction on the roll paper. Roll paper cutting control method, and when the roll paper is discharged in the direction opposite to the sub-scanning direction, if there is a recording-executed recording area that is not cut on the roll paper, The roll paper cutting control method is characterized in that after the roll paper is cut in the vicinity of the final end of the recording area where recording has been performed, the roll paper is discharged in a direction opposite to the sub-scanning direction.

  As described above, when there is an unrecorded recording area on the roll paper, the roll paper is cut in the sub-scanning direction after cutting the roll paper in the vicinity of the final end of the recorded recording area. Since the paper is discharged to the roll paper holder in the direction, the roll paper can be discharged to the roll paper holder in a state where the recording area that has been recorded does not remain on the roll paper.

  Also, by cutting the roll paper in the vicinity of the final end of the recording area where recording has been performed, it is possible to minimize the transport amount when the roll paper is transported in the direction opposite to the sub-scanning direction. When the sheet is conveyed in the direction opposite to the sub-scanning direction, it is possible to minimize the influence on the recording surface on which the roll paper has been recorded by the paper discharge serrated roller or the like.

  Thereby, according to the roll paper cutting control method according to the invention described in claim 2 of the present application, as in the invention described in claim 1 of the present application, in a state where the recording area where recording has been performed remains on the roll paper, Since it is possible to prevent the roll paper from being discharged to the roll paper holder side, it is possible to prevent the roll paper cutter from being able to cut the vicinity of the start and end of the recorded recording area. The effect is obtained.

  Further, by cutting the roll paper in the vicinity of the final end of the recording area where the recording has been performed, when the roll paper is transported in the direction opposite to the sub-scanning direction, the recording of the roll paper by the discharge paper-feeding roller, etc. The effect that the influence on the recording surface can be minimized is also obtained.

When there is no next recording data, the recording execution control is terminated at that time, the roll paper cutting control request waiting state is maintained, and when the roll paper cutting control request is manually operated, The roll paper is transported until the position at which the end of recording at the end of recording reaches the roll paper cutting position, and the roll paper is cut and discharged in the sub-scanning direction. With roll paper cutting control method That.

  As described above, when continuous recording on the roll paper is performed, the next recording is performed as it is without cutting the roll paper at the end of recording of one recording area, and the recording that has been recorded on the roll paper is performed. By cutting the roll paper when the position to be cut between the areas reaches the roll paper cutting position, it is possible to improve the throughput when recording a plurality of recording areas continuously on the roll paper.

  When there is no next recording data, that is, when the last recording area of a plurality of continuous recording areas has been recorded, the roll paper of the last recording area portion is not cut and is not cut in the ink jet recording apparatus. It will be in a standby state in the state which remained in. From this standby state, it is possible to continue recording by the next recording execution control request, and if there is a roll paper cutting control request in the standby state, the end of the recording area where the recording has ended It is also possible to transport the position to be cut to the roll paper cutting position, cut it and discharge it.

  For this reason, when a plurality of recording areas are continuously recorded on the roll paper, the last recorded area is always left in the ink jet recording apparatus and is in a standby state. . That is, the roll paper cutting control method described above has an effect of improving throughput when continuously recording a plurality of recording areas on the roll paper, but the last recorded area is an ink jet recording apparatus. It will remain inside. Therefore, if the roll paper is discharged backward from this state, that is, to the roll paper holder side disposed in the direction opposite to the sub-scanning direction, the recorded recording area remains and is discharged.

If the roll paper discharge button 58 has been pressed (Yes in step S1), it is subsequently determined whether or not a recording operation on the roll paper P is being executed (step S2). If the recording operation on the roll paper P is being executed (Yes in step S2), the recording operation on the roll paper P is continued as it is (step S3), and the process returns to step S1.

  If the recording operation on the roll paper P is not being executed (No in step S2), that is, if the ink jet recording apparatus 50 is not in the recording operation and is in the recording standby state, the ink jet recording apparatus 50 continues. It is determined whether or not there is a recorded recording area on the remaining roll paper P (step S4). If there is no recorded area on the roll paper P (No in step S4), the roll paper P is moved rearward, that is, on the roll paper holder 21 side, and the transport drive roller 53 is moved in the direction opposite to the sub-scanning direction Y. The roll paper P is discharged by rotating it (step S8).

  Needless to say, this discharge operation is executed only when the paper detector 24 detects the roll paper P, that is, when the roll paper P remains in the ink jet recording apparatus 50. It is what is done. Then, when the paper detector 24 stops detecting the roll paper P, the rotation of the transport driving roller 53 is stopped. Alternatively, the length of the roll paper P remaining in the ink jet recording apparatus 50 is calculated from the transport amount in the sub-scanning direction Y so far, and the rotation is performed so that the roll paper P of that length is discharged. It is also possible to discharge the roll paper P by rotating the transport driving roller 53 by an amount.

  On the other hand, if there is a recorded area on the roll paper P (Yes in step S4), it is determined whether or not a cutting request is set for the recorded area (step S5). If there is a recording area in which a cutting request is set (Yes in step S5), the roll paper P for which the cutting request is set is transported to the cutting position of the roll paper cutter 57 and cut. The sheet is discharged in the scanning direction Y (step S6), and the process returns to step S4.

  If there is a recorded recording area (Yes in step S4) and there is no recording area for which a cutting request is set (No in step S5), the end of the recorded recording area is cut by the roll paper cutter 57. It is transported to a position, cut, and discharged in the sub-scanning direction Y (step S7). As a result, the recorded recording area of the roll paper P is completely cut and discharged in the sub-scanning direction Y. Then, the roll paper P is discharged by rotating the transport drive roller 53 in the reverse direction to the sub-scanning direction Y toward the back, that is, the roll paper holder 21 side (step S8).

  FIG. 4 is a schematic plan view of the ink jet recording apparatus 50 according to the present invention, and shows a state in which the roll paper P is fed.
