[Problems to be solved by the invention]
Generally, the ink is not yet sufficiently dried immediately after the recording is completed, and if cutting is started immediately after the recording is completed, the ink may adhere to the roller and contaminate the roll paper. For this reason, in the printer described above, it is necessary to take an interval from the completion of recording to the start of cutting. Therefore, the processing time until the recorded and cut roll paper is completed is long.
[0005]
The present invention has been made in view of the various problems as described above, and an object of the present invention is to provide a recording medium cutting apparatus that can prevent contamination of the medium when the medium is cut, and a recording apparatus including the recording medium cutting apparatus. Is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the recording medium cutting apparatus of the present invention, a cutting unit that cuts a recording portion of a recording medium that has been transported and recorded in a transporting direction and a transporting orthogonal direction, and a cutting unit that is arranged in parallel on one side of the cutting unit. A recording medium cutting device comprising a pressing roller that sometimes presses the recording medium, wherein the cutting means first cuts a portion where the pressing roller does not roll on the recording portion and rolls on the recording portion. It is characterized by cutting the moving part later. As a result, even if the recording portion is in a dry state at the start of cutting, the pressing roller does not roll on the recording portion when cutting first, so that the recording agent does not adhere to the pressing roller. Further, when the sheet is cut later, the pressing roller rolls on the recording portion. At this point, the recording portion is in a dry state, and therefore the recording agent does not adhere to the pressing roller.
[0007]
Further, the location where the pressing roller does not roll is one end of the recording portion in the transport direction and one side in the transport orthogonal direction, and the location where the press roller rolls is the other in the transport orthogonal direction of the recording portion. And the rear end side in the transport direction. As a result, the pressing roller arranged in parallel on one side of the cutting means can press the recording medium without rolling on the recording portion at the leading end side in the transport direction of the recording portion and one side in the transport orthogonal direction. Further, the cutting means cuts the recording portion in the order of the front end side in the transport direction, one side in the transport orthogonal direction, the other side in the transport orthogonal direction, and the rear end side in the transport direction. Further, the cutting means cuts in the order of one side in the conveyance orthogonal direction of the recording portion, the leading end side in the conveyance direction, the other side in the conveyance orthogonal direction, and the rear end side in the conveyance direction. Thereby, after the cutting is completed, the cut of the recording medium is not entangled with the discharge roller or the like, and the recording medium can be smoothly discharged in the transport direction.
[0008]
In addition, when the cutting means is self-propelled in the conveyance orthogonal direction, the recording portion of the recording medium in a stationary state is cut in the conveyance orthogonal direction, and the recording medium is reversely conveyed while the cutting means is stationary. By doing so, the recording portion is cut in the transport direction. Thereby, since the cutting | disconnection means should just move only to a conveyance orthogonal direction, the moving mechanism can be comprised simply. Further, since the recording medium can be cut while being pulled in the reverse conveyance direction, the cutting accuracy can be improved.
[0009]
In addition, the cutting means includes a first cutting unit that cuts the recording portion in the conveyance orthogonal direction and a second cutting unit that cuts the recording portion in the conveyance direction. . Thereby, since the other cutting part can be moved while one cutting part is cutting, the cutting processing time can be shortened. Further, the first cutting portion and the second cutting portion are integrated. Thereby, a moving mechanism can be comprised simply. Further, the cutting means is characterized in that it includes one cutting section whose direction is freely changeable in the transport direction and the transport orthogonal direction. Thereby, since only one cutting blade is required, the replacement operation of the cutting blade is facilitated.
[0010]
In order to achieve the above object, the recording apparatus of the present invention is a recording apparatus that records on a recording medium and cuts the recording portion, and includes the recording medium cutting apparatuses. Thereby, it is possible to provide a recording apparatus that exhibits the action of each recording medium cutting apparatus.

It has come to be.
[0051]
The user can easily pull out the leading end portion of the roll paper by the bearing built in the support portion 151, and the leading end portion of the roll paper can be moved between the feed roller 152 and the pinch roller 153 by the moving mechanism of the pinch roller 153. Since it can be easily inserted and held between them, the number of man-hours for setting the roll paper can be greatly reduced.
[0052]
The pair of arm portions 154 are attached to the opposing surfaces of the two support pillars 142 of the leg portion 140 so as to be rotatable in the direction indicated by the arrows. Then, the rotation of the pair of arm portions 154 is performed by, for example, a locking member provided on the opposing surface of the support pillar 142 at the roll paper setting position shown in FIG. 10 and the roll paper feed position shown in FIG. It is positioned by being locked by a lock mechanism using an urging member or the like.
[0053]
That is, when the pair of arm portions 154 are rotated to the roll paper setting position, the feed roller 152 and the pinch roller 153 jump out to the front side of the ink jet printer 100, and the pair of arm portions 154 feed the roll paper. When rotated to the position, the feed roller 152 and the pinch roller 153 go around the back side of the ink jet printer 100 and are connected to the roll paper transport path.
[0054]
When the user inserts and pinches the leading edge of the roll paper between the feed roller 152 and the pinch roller 153, the user does not sink into the back side of the ink jet printer 100 but does not normally stand on the front side of the ink jet printer 100. Since the work can be performed at the position, the man-hours for setting the roll paper can be greatly reduced.
[0055]
In the above-described embodiment, the pair of support portions 151 are fixedly attached to the facing surfaces of the pair of arm portions 154 arranged to face each other, and rotate with the arm portions 154. Even if it is configured to be fixedly attached to a shaft concentric with the pivot shaft of the arm portion 154 attached to the opposing surfaces of the two support pillars 142, the same effect can be obtained. That is, the support part 151 may be fixed at a fixed position regardless of the rotation of the arm part 154.

Next, as shown in FIG. 12A, for example, the user pushes the feed roller 152 to the back to swing the arm unit 154, and rolls the arm unit 154 positioned at the setting position of the roll paper. Position at the paper feed position. As a result, the leading edge of the roll paper R sandwiched between the pinch roller 153 and the feed roller 152 and the entrance of the paper feed guide 157 are positioned.
[0061]
Here, when the user operates the operation panel 170 to activate the ink jet printer 100, the feed roller 152 starts to rotate as shown in FIG. 12B. Then, the roll paper R sandwiched between the pinch roller 153 and the feed roller 152 is guided by the paper feed guide 157 and sent to the upper recording unit 120. As shown in FIG. 13, the roll paper R is sandwiched between the paper feed roller 125 and its driven roller 126, and is also sandwiched between the paper discharge roller 131 and its driven roller 132 and conveyed in the sub-scanning direction. Predetermined information is recorded by ink droplets ejected from the recording head 121 moving in the scanning direction.
[0062]
After the completion of the recording, as shown in FIG. 14, the roll paper R is reversely conveyed by the reverse rotation of the paper feed roller 125 and the paper discharge roller 131, and the left side of the recording portion in the conveyance direction leading side and the conveyance orthogonal direction is the left side. The conveyance is stopped at a position coinciding with the horizontal cutting cutter 211. Then, the leading end side in the conveyance direction of the recording portion is cut by the movement of the horizontal cutting cutter 211 in the main scanning direction. At this time, the presser roller 220 rolls on the tip side of the cutting line of the horizontal cutting cutter 211 and does not interfere with the recording portion. Therefore, even when the recording portion is in a dry state, the roll paper R due to ink adhesion is used. Contamination can be prevented.
[0063]
Next, the roll paper R is conveyed by the rotation of the paper feed roller 125 and the paper discharge roller 131, and is conveyed at a position on the left side in the conveyance orthogonal direction of the recording portion and the rear end side in the conveyance direction coincides with the vertical cutting cutter 231. Stopped. Then, the left side of the recording portion in the conveyance orthogonal direction is cut by the reverse conveyance of the roll paper R by the reverse rotation of the paper feed roller 125 and the paper discharge roller 131. At this time, the presser roller 240 rolls on the left side of the cutting line of the vertical cutting cutter 231 and does not interfere with the recording portion. Contamination can be prevented.
[0064]
Next, the roll paper R is conveyed by the rotation of the paper feed roller 125 and the paper discharge roller 131, and is conveyed at a position on the right side in the conveyance orthogonal direction of the recording portion and the rear end side in the conveyance direction coincides with the vertical cutting cutter 231. Stopped. Then, the right side of the recording portion in the conveyance orthogonal direction is cut by reverse conveyance of the roll paper R by reverse rotation of the paper feed roller 125 and the paper discharge roller 131. At this time, the pressing roller 240 rolls on the left side of the cutting line of the vertical cutting cutter 231 and interferes with the recording portion. At this time, the recording portion is already in a dry state. It is possible to prevent the roll paper R from being contaminated.
[0065]
Then, the roll paper R is conveyed by the rotation of the paper feed roller 125 and the paper discharge roller 131, and is conveyed at a position where the left side in the conveyance orthogonal direction and the left side in the conveyance orthogonal direction coincides with the horizontal cutting cutter 211. Stopped. Then, the rear end side in the conveyance direction of the recording portion is cut by the movement of the horizontal cutting cutter 211 in the main scanning direction. At this time, the presser roller 240 rolls on the tip side of the cutting line of the horizontal cutting cutter 211 and interferes with the recording portion. At this time, the recording portion is already in a dry state. Contamination of the roll paper R due to adhesion can be prevented. Finally, as shown in FIG. 15, the cut roll paper CR is nipped between the paper discharge roller 131 and its driven roller 132 and discharged.
[0066]
As described above, according to the ink jet printer 100 of the present embodiment, the recording medium cutting devices 200 and 250 first cut the portions where the pressing rollers 220, 240, and 253 do not roll on the recording portion. Even when the recording portion is in a dry state at the start, ink does not adhere to the press rollers 220, 240, and 253. Since the part where the pressing rollers 220, 240, and 253 roll on the recording portion is cut later, the recording portion is in a dry state at that time, and ink adheres to the pressing rollers 220, 240, and 253 again. There is no.
[0067]
Further, the place where the pressing rollers 220, 240, and 253 do not roll is the leading end side of the recording portion in the conveyance direction and one side in the conveyance orthogonal direction, and the portion where the pressing rollers 220, 240, and 253 roll is the recording portion. The other side in the transport orthogonal direction and the rear end side in the transport direction. Accordingly, the pressing rollers 220, 240, and 253 arranged in parallel on one side of the horizontal cutting cutter unit 210, the vertical cutting cutter unit 230, and the cutter 251 are arranged on one side of the recording portion in the conveyance direction and in the conveyance orthogonal direction. The roll paper can be pressed without rolling over the recording portion. Further, the horizontal cutting cutter unit 210, the vertical cutting cutter unit 230, and the cutter 251 are arranged at the leading end side in the transport direction of the recording portion, one side in the transport orthogonal direction, the other side in the transport orthogonal direction, and the rear end side in the transport direction. Since the cutting is performed in order, the cut of the roll paper does not get entangled with the paper discharge roller 131 and the like after the cutting is completed, and the roll paper can be discharged smoothly in the transport direction.
[0068]
Further, the horizontal cut cutter unit 210 and the cutter 251 are self-propelled in the main scanning direction, whereby the recording portion of the roll paper in a stationary state is cut in the main scanning direction. In addition, while the vertical cutting cutter unit 230 and the cutter 251 are stationary, the recording portion is cut in the sub-scanning direction by reversely conveying the roll paper. Therefore, since the horizontal cutting cutter unit 210, the vertical cutting cutter unit 230, and the cutter 251 need only move in the main scanning direction, the moving mechanism can be configured simply. Further, since the cutting can be performed while pulling the roll paper in the reverse conveyance direction, the cutting accuracy can be improved.
