Description

  A recording apparatus comprising: a recording material support member that supports a recording material in a recording execution area; and a conveyance device that conveys the recording material supported by the recording material support member, and a computer that controls the recording apparatus It relates to a control program to be executed.

  Generally, in a recording apparatus such as an ink jet printer or a dot impact printer, a recording material is transported to a recording execution area, and dots are formed on the recording surface of the recording material supported by the recording material support member in the recording execution area. The recording is performed on the recording material. At this time, since the recording material is conveyed while being supported by the recording material support member, the recording material is conveyed while being in sliding contact with the recording material support member. For this reason, static electricity is generated mainly by frictional charging at the portion where the recording material support member and the recording material are in sliding contact, and the static electricity is accumulated between the recording material support member and the recording material. Become. The electrostatic force causes a suction force to act between the recording material support member and the recording material, thereby increasing the sliding resistance and increasing the conveyance load of the recording material. That is, static electricity accumulated between the recording material support member and the recording material can cause a decrease in the conveyance accuracy of the recording material, and a decrease in the conveyance accuracy in the recording apparatus can cause a decrease in the recording accuracy. .

  As a conventional technique capable of solving such a problem, for example, a recording apparatus including a recording material support member subjected to an antistatic treatment is known. More specifically, the recording material support member of this prior art is formed of a plastic mixed with a conductive substance or a surface active agent, or an antistatic coating is applied to the surface. According to the related art, since the antistatic treatment is performed on the recording material support member that is in sliding contact with the recording material, the generation of static electricity is reduced, so the recording material support member and the recording material It is possible to reduce a decrease in recording accuracy due to static electricity accumulated in the meantime (see, for example, Patent Document 1).

JP 2000-289290 A

  However, plastics incorporating conductive materials or surfactants are generally more expensive than plastics that are not. For this reason, when a recording material support member formed of such plastic is employed, the cost of the recording apparatus may increase significantly. Further, if an antistatic coating is applied to the surface of the recording material support member, this increases the number of manufacturing processes, and there is a risk that the cost of the recording apparatus will increase significantly. In addition, since the antistatic treatment effect of members subjected to such antistatic treatment gradually deteriorates due to wear or deterioration due to aging, there is a recent need for extending the life of recording devices. May not be possible.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a recording material support member and a recording material without using a recording material support member that has been subjected to antistatic treatment. It is intended to reduce a decrease in recording accuracy due to static electricity accumulated during the period.

<First Aspect of the Present Invention>
According to a first aspect of the present invention, there is provided a recording material support member that supports a recording material in a recording execution area, a conveyance device that conveys the recording material supported by the recording material support member, and the recording material A recording apparatus comprising: a negative pressure generating device that generates a negative pressure in a suction hole formed in a support surface of a support member; and a control device, wherein the control device generates a negative pressure in the suction hole. In this state, a means for conveying the recording material before recording to a predetermined standby position supported by the recording material support member, and before starting recording on the recording material, In the state where no pressure is generated or in the state where a negative pressure lower than that at the time of execution of recording is generated in the suction hole, the standby position is once set by performing transport in the forward feed direction and transport in the reverse feed direction. After transporting the recording material to a position different from Means for transporting the recording medium to, and means for performing recording on the recording medium in a state in which negative pressure is generated in the suction hole, it is a recording apparatus wherein.

  In the process of transporting the recording material before recording to a predetermined standby position supported by the recording material support member, for example, a so-called skew removal operation or cueing / positioning operation of the recording material is generally performed. It is. These operations are a negative pressure that generates a negative pressure in the suction hole formed on the support surface of the recording material support member (the surface that supports the recording material, and the portion where the recording material is in sliding contact, the same applies hereinafter). In a recording apparatus provided with a generating device, it is desirable to carry out in a state in which a negative pressure is generated in the suction hole in order to realize more accurate skew removal and cueing / positioning of the recording material. Also, when recording on the recording material, in order to achieve higher accuracy recording by transporting the recording material with higher accuracy, the suction holes formed on the support surface of the recording material support member are also loaded. It is desirable that pressure be generated. In a state in which a negative pressure is generated in the suction hole, the recording material is adsorbed on the support surface of the recording material support member, so that the recording material support member is deformed due to warpage or curl deformation of the recording material. This is because the recording material is restrained from floating from the support surface.

  On the other hand, when the recording material is attracted to the support surface of the recording material support member, the sliding resistance of the recording material increases. For this reason, static electricity generated at the portion where the recording material support member and the recording material are in sliding contact with each other increases, and as a result, static electricity accumulated between the recording material support member and the recording material increases. It becomes. In particular, in the so-called skew removal operation, cueing / positioning operation, etc. of the recording material, the recording material attracted to the support surface of the recording material support member is conveyed in the forward feed direction and in the reverse feed direction. In many cases, the above-described conveyance is repeated alternately and a plurality of times, so that static electricity tends to be accumulated.

  For this reason, in the first aspect of the present invention, when the recording material before recording is first transported to the standby position, a negative pressure is generated in the suction hole. Thereby, for example, a so-called skew removal operation, cueing / positioning operation, and the like of the recording material can be performed with high accuracy.

  Next, before starting recording on the recording material at the standby position, in a state where a negative pressure is not generated in the suction hole or in a state where a negative pressure lower than that at the time of recording is generated in the suction hole, Transport in the forward direction and transport of the recording material in the reverse direction. As a result, the static electricity accumulated between the recording material support member and the recording material in the process of transporting the recording material before recording to the standby position is discharged before starting recording on the recording material. Is promoted and reduced. This is because the recording material is removed from the support surface of the recording material support member by setting the suction hole to a state where no negative pressure is generated or a state where a negative pressure is generated in the suction hole. This is considered to be due to the fact that the space between the two is slightly lifted and the distance between the two is increased, thereby promoting the natural discharge of static electricity accumulated between the recording material support member and the recording material into the atmosphere. Further, by carrying the paper in the forward direction and the backward direction from that state, the conveying device comes into contact with a wide range of the recording material, and thereby, the recording material passes through the conveying device. This is thought to be due to the accelerated discharge of static electricity to the housing.

  The transport in the forward feed direction and the transport in the reverse feed direction are performed in a state where no negative pressure is generated in the suction holes or in a state where a negative pressure lower than that at the time of recording is generated in the suction holes. Therefore, the recording is performed in a state where the sliding resistance of the recording material is greatly reduced. Accordingly, it is considered that the static electricity generated at the portion where the recording material support member and the recording material are in sliding contact with each other is suppressed to an extremely small amount.

  Then, after the recording material is transported to the standby position again, recording on the recording material is performed in a state where a negative pressure is generated in the suction hole. Accordingly, recording can be performed on the recording material with relatively little static electricity accumulated between the recording material support member and the recording material, so that the recording material support member and the recording material can be recorded. A decrease in recording accuracy due to static electricity accumulated with the material can be reduced. In addition, by performing recording in a state where a negative pressure is generated in the suction hole, it becomes possible to convey the recording material with high accuracy, and thus it is possible to realize highly accurate recording.

  As described above, according to the first aspect of the present invention, the recording material support member that has been subjected to the antistatic treatment is accumulated between the recording material support member and the recording material without using the recording material support member. An effect is obtained that a reduction in recording accuracy due to static electricity can be reduced.

<Second Aspect of the Present Invention>

Means for performing recording on the recording material in a state where the suction hole is in a state where no negative pressure is generated in the suction hole or a state where a negative pressure lower than that at the time of recording is generated in the suction hole. And a means for conveying the recording material after execution of recording to a position where there is an unrecorded portion at a predetermined standby position supported by the recording material support member.

  As described above, by performing recording on the recording material in a state where negative pressure is generated in the suction hole, it becomes possible to convey the recording material with high accuracy, thereby realizing high accuracy recording. Can do. However, for example, when continuous recording is performed on a long recording material wound on a shaft (so-called roll paper, etc.), a high sliding contact resistance is generated by the negative pressure generated in the suction hole. In such a state, the recording material continues to be in sliding contact with the support surface of the recording material support member. For this reason, the static electricity accumulated between the recording material supporting member and the recording material is gradually gradually discharged into the atmosphere gradually, but often gradually increases at a pace exceeding it.

  With respect to such static electricity, the second aspect of the present invention performs suction when the recording material is transported to a position where there is an unrecorded portion at the standby position after recording on the recording material. A state where no negative pressure is generated in the hole or a state where a negative pressure lower than that at the time of recording is generated is set in the suction hole. Accordingly, the static electricity accumulated between the recording material and the recording material support member during the recording is promoted and reduced, as in the first aspect.

  Then, recording on the unrecorded portion of the recording material is started from this state. As a result, recording on an unrecorded portion of the recording material can be continued in a state where static electricity accumulated between the recording material support member and the recording material is relatively small. In addition, by performing recording in a state where a negative pressure is generated in the suction hole, it becomes possible to convey the recording material with high accuracy, and thus it is possible to realize highly accurate recording.

  As described above, according to the second aspect of the present invention, the recording material support member subjected to the antistatic treatment is accumulated between the recording material support member and the recording material without using the recording material support member. An effect is obtained that a reduction in recording accuracy due to static electricity can be reduced.

And a predetermined member supported by the recording material support member in a state in which no negative pressure is generated in the suction hole or in a state in which a negative pressure lower than that during execution of recording is generated in the suction hole. Means for transporting an unrecorded portion of the recording material after cutting to a standby position of Having, it is a recording apparatus wherein.

  When recording is performed on the recording material, the recorded portion of the recording material is cut, and when the recording material is transported to a position where there is an unrecorded portion at the standby position after cutting, the suction hole In a state where no negative pressure is generated or a negative pressure lower than that at the time of recording is generated in the suction hole. Accordingly, the static electricity accumulated between the recording material and the recording material support member during the recording is promoted and reduced, as in the first aspect.

  Then, recording on the unrecorded portion of the recording material is started from this state. As a result, recording on an unrecorded portion of the recording material can be continued in a state where static electricity accumulated between the recording material support member and the recording material is relatively small. In addition, by performing recording in a state where a negative pressure is generated in the suction hole, it becomes possible to convey the recording material with high accuracy, and thus it is possible to realize highly accurate recording.

<First embodiment>
A first embodiment of recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIGS. 3 and 10.

FIG. 10 is a side view of an essential part of the inkjet printer 1, and schematically shows the positional relationship between the transport position of the cut sheet P or roll paper RP and each component.
The standby position C is a recording start position when ink is ejected from the head surface of the recording head 17 to execute recording. The cutting position D is a position where the roll paper RP can be cut by the cutting device 29. The first transport position Y1 is set upstream of the recording paper support member 13 in the sub-scanning direction Y, and the leading edge of the cut sheet P or roll paper RP in the sub-scanning direction Y is located at the first transport position Y1. In this state, it is set to a position where the support surface of the recording paper support member 13 is opened (position where the support surface of the recording paper support member 13 is not substantially in contact with the cut paper P or roll paper RP). . The second transport position Y2 is set downstream of the recording paper support member 13 in the sub-scanning direction Y, and can be set at any position as long as it is downstream of the standby position C in the sub-scanning direction Y. .

FIG. 3 is a flowchart of the first embodiment, and illustrates a procedure for executing recording on the cut sheet P.
In this embodiment, all procedures are executed with the suction device 37 in the suction OFF state (a state where no negative pressure is generated in the suction hole of the recording paper support member 13; the same applies hereinafter). That is, in this embodiment, the suction device 37 may not be provided in the inkjet printer 1.

  First, the cut sheet P before recording is fed to the standby position C (FIG. 10) (step S1). More specifically, the cut sheet P is fed by an automatic feeding device (not shown), and a so-called skew removing operation, cueing / positioning operation, and the like are performed on the fed cut sheet P. . Then, the cut sheet P before recording is conveyed to a position where the leading end in the sub-scanning direction Y reaches the standby position C.

  Subsequently, the cut sheet P before recording is fed back to the open position (step S2). More specifically, the recording paper support member 13 is transported in the reverse feeding direction RY by transporting the cut sheet P before recording to a position where the leading end in the sub-scanning direction Y reaches the first transport position Y1 (FIG. 10). The support surface of is temporarily opened. As a result, the static electricity accumulated between the recording paper support member 13 and the cut sheet P in the process of so-called skew removal operation, cueing / positioning operation, etc. is accelerated and reduced.

  This is because once the support surface of the recording paper support member 13 is opened, spontaneous discharge of static electricity accumulated between the recording paper support member 13 and the cut paper P into the atmosphere is promoted. It is considered a thing. Furthermore, in the process of transporting the cut sheet P to at least the position where the support surface of the recording paper support member 13 is opened, the transport drive roller 11 contacts the wide range of the cut sheet P, whereby the cut sheet P It is thought that this is because it is promoted that static electricity is discharged to the casing of the ink jet printer 1 through the transport driving roller 11.

  Subsequently, the cut sheet P before recording is conveyed again to the standby position C (step S3). More specifically, the cut sheet P before recording is conveyed in the sub-scanning direction Y to the position where the leading edge in the sub-scanning direction Y reaches the standby position C. That is, the cut paper P before recording is transported from the standby position C to the first transport position Y1, the support surface of the recording paper support member 13 is once opened, and then the cut paper P is transported to the standby position C again. (Reference E2 in FIG. 10). As a result, the static electricity accumulated between the recording paper support member 13 and the cut paper P can be recorded on the cut paper P with relatively little static electricity. It is possible to reduce a decrease in recording accuracy due to the above.

  From this state, recording is performed on the cut sheet P (step S4), and the cut sheet P is discharged (step S5). Subsequently, it is determined whether or not unrecorded data remains (step S6). If unrecorded data remains (Yes in step S6), the process returns to step S1 to feed the next cut sheet P. If no unrecorded data remains (No in step S6), the procedure is terminated as it is.

  In this way, according to the present invention, the recording paper support member or the like that has been subjected to antistatic treatment is used, and this is caused by static electricity accumulated between the recording paper support member 13 and the cut paper P. A decrease in recording accuracy can be reduced.

<Second embodiment>
A second embodiment of recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG. 4 and subsequently FIG.
FIG. 4 is a flowchart of the second embodiment, and illustrates a procedure for executing recording on the roll paper RP.
In this embodiment, all the procedures are executed with the suction device 37 in the suction OFF state. That is, in this embodiment, the suction device 37 may not be provided in the inkjet printer 1.

  The procedure from steps S11 to S14 in the second embodiment (FIG. 4) is the same as the procedure from steps S1 to S4 in the first embodiment (FIG. 3) except that the target is roll paper RP. is there. That is, in steps S12 and S13 of the second embodiment, the roll paper RP before recording is transported from the standby position C to the first transport position Y1 and the support surface of the recording paper support member 13 is moved as in the first embodiment. After being released once, the roll paper RP is conveyed again to the standby position C (reference numeral E2 in FIG. 10). As a result, the static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of so-called skew removal operation, cueing / positioning operation, etc. is accelerated and reduced.

  After recording on the roll paper RP (step S14), the roll paper RP is cut near the boundary between the recorded portion and the unrecorded portion (step S15), and the recorded portion of the cut roll paper RP is discharged (step S15). Step S16). More specifically, after recording is performed, the roll paper RP is conveyed in the sub-scanning direction Y to the position where the vicinity of the boundary between the recorded portion and the unrecorded portion reaches the cutting position D (FIG. 10). And the vicinity of the boundary between the unrecorded portion is cut by the cutting device 29, and the recorded portion of the cut roll paper RP is discharged.

  Subsequently, it is determined whether or not unrecorded data remains (step S17). If no unrecorded data remains (No in step S17), the unrecorded portion of the roll paper RP is sent back to the standby position C (step S18), and the procedure is terminated. More specifically, the unrecorded portion of the roll paper RP is conveyed in the reverse feeding direction RY until the leading end in the sub-scanning direction Y reaches the standby position C, and the procedure ends (reference E4 in FIG. 10).

  On the other hand, if unrecorded data remains (Yes in step S17), the process returns to step S12. That is, the unrecorded portion of the roll paper RP is sent back to the open position (step S12). More specifically, the unrecorded portion of the roll paper RP with the leading end in the sub-scanning direction Y at the cutting position D is transported in the reverse feed direction RY to a position that reaches the first transport position Y1 (FIG. 10). Thus, the support surface of the recording paper support member 13 is once opened. Accordingly, static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of recording on the roll paper RP is accelerated and reduced. Subsequently, the unrecorded portion of the cut roll paper RP is conveyed to the standby position C (step S13). More specifically, the unrecorded portion of the roll paper RP is conveyed in the sub-scanning direction Y until the leading end in the sub-scanning direction Y reaches the standby position C.

  That is, the unrecorded portion of the roll paper RP after cutting is reversely fed from the cutting position D to the first transport position Y1 to once open the support surface of the recording paper support member 13, and then the unrecorded portion of the roll paper RP is removed. Transport to the standby position C (reference numeral E5 in FIG. 10). Thereby, recording is continued on the unrecorded portion of the cut roll paper RP in a state where the static electricity accumulated between the unrecorded portion of the roll paper RP after the cut and the recording paper support member 13 is relatively small. It becomes possible to do. Therefore, even when recording is continuously performed on the roll paper RP and the recorded portions are sequentially cut, it is possible to reduce a decrease in recording accuracy due to the static electricity.

  In this way, according to the present invention, recording due to static electricity accumulated between the recording paper support member 13 and the roll paper RP can be performed without using a recording paper support member or the like that has been subjected to antistatic treatment. A decrease in accuracy can be reduced.

<Third embodiment>
A third embodiment of the recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG. 5 and subsequently FIG.
FIG. 5 is a flowchart of the third embodiment, and illustrates a procedure for recording on the cut sheet P.

  First, the suction device 37 is operated to make the suction ON state (a state in which negative pressure is generated in the suction hole of the recording paper support member 13; the same applies hereinafter) (step S21), and the cut sheet P before recording is waited. Feed to position C (FIG. 10) (step S22). The feeding procedure in step S22 is the same as the feeding procedure in step S1 (FIG. 3) in the flowchart of the first embodiment. By performing so-called skew removal operation, cueing / positioning operation, etc. in the suction ON state in this manner, the cut sheet P is prevented from floating from the recording paper support member 13 during these operations. It can be performed with higher accuracy.

  Subsequently, the operation of the suction device 37 is stopped to make the suction OFF state (step S23), and the cut sheet P before recording is conveyed in the normal feeding direction (sub-scanning direction Y) (step S24). More specifically, the cut sheet P before recording is transported in the sub-scanning direction Y to the position where the leading end in the sub-scanning direction Y reaches the second transport position Y2 (FIG. 10) in the suction OFF state. Subsequently, the cut sheet P before recording is conveyed in the reverse feed direction (reverse feed direction RY) (step S25). More specifically, the cut sheet P before recording is conveyed in the reverse feed direction (reverse feed direction RY) to the position where the leading edge in the sub-scanning direction Y reaches the standby position C in the suction OFF state.

  That is, in the suction OFF state, the cut sheet P before recording is transported from the standby position C to the second transport position Y2, and then transported to the standby position C again (reference numeral E1 in FIG. 10). Thereby, static electricity accumulated between the recording paper support member 13 and the cut paper P in the process of feeding the pre-recorded cut paper P to the standby position C starts recording on the cut paper P. Before, its discharge is promoted and reduced.

  This is because when the operation of the suction device 37 is stopped and the suction is turned off, the cut sheet P is slightly lifted from the support surface of the recording paper support member 13 and the interval therebetween is increased, whereby the recording paper support member This is thought to be due to the accelerated natural discharge of static electricity accumulated between the paper 13 and the cut sheet P into the atmosphere. Furthermore, the conveyance drive roller 11 contacts the wide range of the cut sheet P by performing conveyance in the forward feeding direction (sub-scanning direction Y) and conveyance in the reverse feeding direction (reverse feeding direction RY) from that state. Therefore, it is considered that the discharge of static electricity from the cut sheet P to the casing of the inkjet printer 1 through the transport driving roller 11 is promoted.

  The conveyance in the forward feeding direction and the conveyance of the cut sheet P in the reverse feeding direction are performed in the suction OFF state, and therefore, performed in a state in which the sliding resistance of the cut sheet P is greatly reduced. become. Therefore, it is considered that the static electricity generated at the portion where the recording paper support member 13 and the cut sheet P are in sliding contact with each other at this time is suppressed to an extremely small amount.

  Then, after the cut sheet P is conveyed again to the standby position C (step S25), the suction sheet is turned on (step S26), and recording is performed on the cut sheet P (step S27). Thereby, recording can be executed on the cut sheet P in a state where the static electricity accumulated between the recording sheet support member 13 and the cut sheet P is relatively small. It is possible to reduce a decrease in recording accuracy caused by static electricity accumulated between the cut paper P. In addition, by performing recording in the suction ON state, it is possible to transport the cut sheet P with high accuracy, and thus it is possible to realize high accuracy recording.

  Subsequently, the cut sheet P after execution of recording is discharged (step S28), and the suction is turned off (step S29). Subsequently, it is determined whether or not unrecorded data remains (step S30). If unrecorded data remains (Yes in step S30), the process returns to step S21, and the next cut sheet P is fed in the suction ON state. If unrecorded data does not remain (No in step S30), the procedure is terminated as it is.

  In this way, according to the present invention, the recording paper support member or the like that has been subjected to antistatic treatment is used, and this is caused by static electricity accumulated between the recording paper support member 13 and the cut paper P. A decrease in recording accuracy can be reduced.

<Fourth embodiment>
A fourth embodiment of the recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG. 6 and FIG.
FIG. 6 is a flowchart of the fourth embodiment and illustrates a procedure for executing recording on the roll paper RP.

  The procedure from Steps S31 to S37 in the fourth embodiment (FIG. 6) is the same as the procedure from Steps S21 to S27 in the third embodiment described above (FIG. 5) except that the target is roll paper RP. is there. That is, in steps S34 and S35 of the fourth embodiment, as in the third embodiment, after the roll paper RP before recording is transported from the standby position C to the second transport position Y2 in the suction OFF state, the standby position is again set. It will carry to C (code | symbol E1 of FIG. 10). Thereby, the static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of feeding the roll paper RP before recording to the standby position C, before starting recording on the roll paper RP, The discharge is promoted and reduced.

  After recording on the roll paper RP (step S37), it is determined whether or not unrecorded data remains (step S38). If unrecorded data remains (Yes in step S38), the suction OFF state is set (step S39), and the roll paper RP is moved in the reverse feed direction RY to a position where the unrecorded portion of the roll paper RP becomes the standby position C. After the conveyance (step S40), the process returns to step S34. More specifically, after the roll paper RP is conveyed in the reverse feed direction RY to the position where the vicinity of the boundary between the recorded portion and the unrecorded portion of the roll paper RP reaches the standby position C in the suction OFF state (FIG. 10). No. E3), the process returns to step S34. In this way, by transferring the unrecorded portion of the roll paper RP back to the standby position C in the suction OFF state, it is accumulated between the recording paper support member 13 and the roll paper RP in the process of executing recording on the roll paper RP. Similarly to the case where the procedures of steps S33 to S35 are performed, the static electricity is accelerated and reduced before the next recording is started on the unrecorded portion of the roll paper RP.

  On the other hand, if no unrecorded data remains (No in step S38), the roll paper RP is cut near the boundary between the recorded portion and the unrecorded portion (step S41), and the cut roll paper RP is recorded. The part is discharged (step S42). More specifically, after recording, the roll paper RP is conveyed in the sub-scanning direction Y to the position where the vicinity of the boundary between the recorded portion (last recorded portion) and the unrecorded portion reaches the cutting position D (FIG. 10). Then, the vicinity of the boundary between the recorded portion and the unrecorded portion is cut by the cutting device 29, and the recorded portion of the cut roll paper RP is discharged. Then, after the suction OFF state is set (step S43), the unrecorded portion of the roll paper RP is sent back to the standby position C (step S44), and the procedure is finished. More specifically, after the suction OFF state is set, the unrecorded portion of the roll paper RP is conveyed in the reverse feeding direction RY to the position where the leading edge in the sub-scanning direction Y reaches the standby position C, and the procedure is finished ( Symbol E4 in FIG.

  In this way, according to the present invention, recording due to static electricity accumulated between the recording paper support member 13 and the roll paper RP can be performed without using a recording paper support member or the like that has been subjected to antistatic treatment. A decrease in accuracy can be reduced.

<Fifth embodiment>
A fifth embodiment of recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG.
FIG. 7 is a flowchart of the fifth embodiment, and illustrates a procedure for executing recording on the roll paper RP.
In the fourth embodiment described above, recording is continuously performed on the roll paper RP without cutting, whereas in the fifth embodiment, when recording is continuously performed on the roll paper RP, the roll paper RP is recorded. The point of difference is that the recorded portion is cut each time recording is performed.

  The procedure from step S51 to step S57 (FIG. 7) of the fifth embodiment is the same as the procedure from step S31 to S37 (FIG. 6) of the fourth embodiment described above, and a description thereof will be omitted.

  After recording on the roll paper RP (step S57), the roll paper RP is cut near the boundary between the recorded portion and the unrecorded portion (step S58), and the recorded portion of the cut roll paper RP is discharged (step S58). Step S59). More specifically, after recording is performed, the roll paper RP is conveyed in the sub-scanning direction Y to the position where the vicinity of the boundary between the recorded portion and the unrecorded portion reaches the cutting position D (FIG. 10). And the vicinity of the boundary between the unrecorded portion is cut by the cutting device 29, and the recorded portion of the cut roll paper RP is discharged.

  Subsequently, after the suction OFF state is set (step S60), the unrecorded portion of the roll paper RP is sent back to the standby position C (step S61). More specifically, in the suction OFF state, the unrecorded portion of the roll paper RP is conveyed in the reverse feeding direction RY to the position where the leading end in the sub-scanning direction Y reaches the standby position C (reference numeral E4 in FIG. 10). In this way, by transferring the unrecorded portion of the roll paper RP back to the standby position C in the suction OFF state, it is accumulated between the recording paper support member 13 and the roll paper RP in the process of executing recording on the roll paper RP. Similarly to the case where the procedure of steps S53 to S55 is executed, the static electricity is accelerated and reduced before the next recording is started on the unrecorded portion of the roll paper RP.

Then, it is determined whether or not unrecorded data remains (step S62). If no unrecorded data remains (No in step S62), the procedure is terminated as it is. If unrecorded data remains (Yes in step S62), the process returns to step S54 to continue recording on the unrecorded portion of the roll paper RP.
Note that the static electricity accumulated between the recording paper support member 13 and the roll paper RP during the process of recording on the roll paper RP has already been promoted and reduced in the procedure of step S61. Therefore, depending on the level of static electricity accumulated between the recording paper support member 13 and the roll paper RP when the procedure of step S61 is executed, the process returns to step S56 as it is and immediately enters the unrecorded portion of the roll paper RP. Recording may be continued.

  In this way, according to the present invention, recording due to static electricity accumulated between the recording paper support member 13 and the roll paper RP can be performed without using a recording paper support member or the like that has been subjected to antistatic treatment. A decrease in accuracy can be reduced.

<Sixth embodiment>
A sixth embodiment of recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG.
FIG. 8 is a flowchart of the sixth embodiment, and illustrates a procedure for executing recording on the cut sheet P.

  The procedure from Steps S71 to S73 (FIG. 8) in the sixth embodiment is the same as the procedure from Steps S21 to S23 in the third embodiment (FIG. 5), and a description thereof will be omitted. After the suction OFF state is set (step S73), it is determined whether or not the type of the cut sheet P fed is glossy paper (step S74). The type of the cut sheet P fed here can be specified by referring to the type of the cut sheet P selected by the user on the setting screen of the printer driver, for example.

  If the type of the cut sheet P before recording is not glossy paper (No in step S74), after the sheet P before recording is conveyed in the normal feed direction (sub-scanning direction Y) ( In step S75, the sheet is conveyed in the reverse feed direction (reverse feed direction RY) (step S76). Steps S75 and S76 (FIG. 8) are the same as steps S24 and S25 (FIG. 5) of the third embodiment described above. That is, in the suction OFF state, the cut sheet P before recording is transported from the standby position C to the second transport position Y2, and then transported again to the standby position C (reference numeral E1 in FIG. 10). By this procedure, static electricity accumulated between the recording paper support member 13 and the cut paper P in the process of feeding the cut paper P before recording to the standby position C starts recording on the cut paper P. Before that, the discharge is promoted and reduced. Hereinafter, the procedure of steps S75 and S76 (FIG. 8) is referred to as “first pre-recording transport operation”.

  On the other hand, when the type of the cut sheet P before recording is glossy paper (Yes in step S74), the sheet P before recording is fed back to the open position (step S77). It is transported again to the standby position C (step S78). Steps S77 and S78 (FIG. 8) are the same as steps S2 and S3 (FIG. 3) of the first embodiment described above. That is, in the suction OFF state, the cut sheet P before recording is transported from the standby position C to the first transport position Y1, the support surface of the recording paper support member 13 is once opened, and then the cut sheet paper is again reached to the standby position C. P is conveyed (reference numeral E2 in FIG. 10). By this procedure, static electricity accumulated between the recording paper support member 13 and the cut paper P in the process of feeding the cut paper P before recording to the standby position C starts recording on the cut paper P. Before that, the discharge is promoted and reduced. Hereinafter, the procedure of steps S77 and S78 (FIG. 8) is referred to as “second pre-recording transport operation”.

  The first pre-recording transport operation (procedures in steps S75 and S76) and the second pre-recording transport operation (procedures in steps S77 and S78) are both processes in which the cut sheet P before recording is fed to the standby position C. The discharge of static electricity accumulated between the recording paper support member 13 and the cut paper P can be promoted, and the static electricity can be reduced. When the operations are compared, the first pre-recording conveyance operation (reference numeral E1 in FIG. 10) does not convey the cut sheet P to the position where the support surface of the recording sheet support member 13 is opened. The transport amount of the paper P can be made smaller than the second pre-recording transport operation (reference numeral E2 in FIG. 10). Therefore, it can be performed in a shorter time, and is more advantageous than the second pre-recording transport operation in terms of throughput. On the other hand, in the second pre-recording transport operation, since the support surface of the recording paper support member 13 is once opened, the discharge of static electricity accumulated between the recording paper support member 13 and the cut sheet P is further promoted. Therefore, the effect of reducing the static electricity is higher than that in the first pre-recording transport operation.

For this reason, the sixth embodiment of the present invention suppresses a decrease in throughput for other cut paper P having a property that is relatively difficult to be charged with static electricity such as plain paper (No in step S74). The first pre-recording transport operation that can be executed in a shorter time is selected and executed (steps S75 and S76). On the other hand, for the cut sheet P having a property that the static electricity is relatively easily charged, such as glossy paper (Yes in step S74), the static electricity accumulated between the recording paper support member 13 and the cut sheet P is reduced. The second pre-recording transport operation with higher effect is selected and executed (steps S77 and S78). As a result, it is possible to accurately reduce a decrease in recording accuracy due to static electricity accumulated between the recording paper support member 13 and the cut sheet P, and to minimize a decrease in throughput due thereto. Become.
Note that whether or not the cut sheet P is easily charged with static electricity depends on the material of the cut sheet P, the structure and material of the coat layer, and the like. That is, whether or not the cut sheet P is easily charged with static electricity can be specified by the type of the cut sheet P.

  Then, after the suction is turned on (step S79), recording on the cut sheet P is started (step S80). As a result, it is possible to convey the cut sheet P with high accuracy, and thus it is possible to realize highly accurate recording. The procedure from step S79 to S83 (FIG. 8) of the sixth embodiment is the same as the procedure from step S26 to S30 (FIG. 5) of the third embodiment described above, and thus the description thereof is omitted.

  In this way, according to the present invention, the recording paper support member or the like that has been subjected to antistatic treatment is used, and this is caused by static electricity accumulated between the recording paper support member 13 and the cut paper P. A decrease in recording accuracy can be reduced.

<Seventh embodiment>
A seventh embodiment of recording control executed by the control device 100 in the inkjet printer 1 will be described with reference to FIG. 9 and subsequently FIG.
FIG. 9 is a flowchart of the seventh embodiment, and illustrates a procedure for executing recording on the roll paper RP.

  The procedure from step S91 to S100 in the seventh embodiment (FIG. 9) is the same as the procedure from step S71 to S80 in the sixth embodiment described above (FIG. 8) except that the target is roll paper RP. is there. That is, in steps S95 to S98 of the seventh embodiment, the roll paper RP before recording is waited by the first pre-recording transport operation (steps S95 and S96) or the second pre-recording transport operation (steps S97 and S98). The static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of feeding to the position C is accelerated and reduced before the recording is started on the roll paper RP.

  After recording on the roll paper RP (step S100), the roll paper RP is cut in the vicinity of the boundary between the recorded portion and the unrecorded portion (step S101), and the recorded portion of the cut roll paper RP is discharged (step S101). Step S102). More specifically, after recording is performed, the roll paper RP is conveyed in the sub-scanning direction Y to the position where the vicinity of the boundary between the recorded portion and the unrecorded portion reaches the cutting position D (FIG. 10). And the vicinity of the boundary between the unrecorded portion is cut by the cutting device 29, and the recorded portion of the cut roll paper RP is discharged.

  Subsequently, after the suction OFF state is set (step S103), it is determined whether the type of roll paper RP is glossy paper (step S104). If the type of roll paper RP is not glossy paper (No in step S104), the unrecorded portion of the roll paper RP is sent back to the standby position C (step S105). More specifically, in the suction OFF state, the unrecorded portion of the cut roll paper RP is transported in the reverse feed direction RY to the position where the leading edge in the sub-scanning direction Y reaches the standby position C (reference E4 in FIG. 10). ). By this procedure, the static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of recording on the roll paper RP starts the next recording on the unrecorded portion of the roll paper RP after the cutting. Before that, the discharge is promoted and reduced. Hereinafter, the procedure of FIG. 9 (FIG. 9) is referred to as “first post-recording transport operation”.

  On the other hand, if the type of roll paper RP is glossy paper (Yes in step S104), the unrecorded portion of the roll paper RP is sent back to the open position (step S106) and then conveyed again to the standby position C. (Step S107). Steps S106 and S107 (FIG. 9) are the same as steps S12 and S13 (FIG. 4) of the second embodiment described above. That is, in the suction OFF state, the unrecorded portion of the cut roll paper RP is fed back from the cutting position D to the first transport position Y1 to once open the support surface of the recording paper support member 13, and then the roll paper RP The unrecorded portion is conveyed to the standby position C (reference numeral E5 in FIG. 10). By this procedure, the static electricity accumulated between the recording paper support member 13 and the roll paper RP in the process of recording on the roll paper RP starts the next recording on the unrecorded portion of the roll paper RP after the cutting. Before that, the discharge is promoted and reduced. Hereinafter, the procedure of steps S106 and S107 (FIG. 9) is referred to as “second post-recording transport operation”.

  The first post-recording transport operation (procedure in step S105) and the second post-recording transport operation (procedure in steps S106 and S107) are both performed in the process of recording on the roll paper RP and the recording paper support member 13 and the roll paper RP. It is possible to promote the discharge of static electricity accumulated between and reduce the static electricity. In contrast, the first post-recording transport operation (reference numeral E4 in FIG. 10) does not transport the roll paper RP to the position where the support surface of the recording paper support member 13 is opened. Can be made smaller than the second post-recording transport operation (reference numeral E5 in FIG. 10). Therefore, it can be performed in a shorter time, and is more advantageous than the transport operation after the second recording in terms of throughput. On the other hand, in the second post-recording transport operation, since the support surface of the recording paper support member 13 is once opened, the discharge of static electricity accumulated between the recording paper support member 13 and the roll paper RP is further promoted. Therefore, the effect of reducing the static electricity is higher than that in the first post-recording transport operation.

  For this reason, in the seventh embodiment of the present invention, priority is given to suppressing a reduction in throughput for other roll paper RP having a property that is relatively difficult to be charged with static electricity such as plain paper (No in step S104). Then, the first post-recording transport operation that can be executed in a shorter time is selected and executed (step S105). On the other hand, for the cut sheet P that has a property of being relatively easily charged with static electricity such as glossy paper (Yes in step S104), the static electricity accumulated between the recording paper support member 13 and the roll paper RP is reduced. Priority is given to the effect, and the second post-recording transport operation with higher effect is selected and executed (steps S106 and S107). Accordingly, it is possible to appropriately reduce a decrease in recording accuracy due to static electricity accumulated between the recording paper support member 13 and the roll paper RP, and to minimize a decrease in throughput. .

  Then, it is determined whether or not unrecorded data remains (step S108). If no unrecorded data remains (No in step S108), the procedure is terminated as it is. If unrecorded data remains (Yes in step S108), the process returns to step S99 to continue recording on the unrecorded portion of the roll paper RP.

  In this way, according to the present invention, recording due to static electricity accumulated between the recording paper support member 13 and the roll paper RP can be performed without using a recording paper support member or the like that has been subjected to antistatic treatment. A decrease in accuracy can be reduced.

<Other embodiments and modifications>
The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  For example, step S2 (FIG. 3) of the first embodiment, step S12 (FIG. 4) of the second embodiment, step S77 (FIG. 8) of the sixth embodiment, and steps S97 and S106 (FIG. 9) of the seventh embodiment. ), If a large part of the support surface of the recording paper support member 13 is substantially open, for example, part of the cut paper P or roll paper RP is supported by the recording paper support member 13. Even in a state where it is in contact with the surface, the purpose of promoting spontaneous discharge of static electricity into the atmosphere is achieved. And, it is more preferable that all the support surfaces of the recording paper support member 13 are opened, since the natural discharge of static electricity into the atmosphere can be further promoted.

  Further, for example, in the third to seventh embodiments, instead of setting the “suction OFF state”, the suction ON state may be set with a suction force weaker than that during feeding and recording. That is, a negative pressure lower than that at the time of feeding the sheet paper P or the roll paper RP and at the time of recording may be generated in the suction hole of the support surface of the recording paper support member 13.

  In the first embodiment and the second embodiment, the suction device 37 is not an essential component, and an embodiment in which the suction device 37 is not provided (an embodiment in which the suction device is always in the suction OFF state) has been described as an example. When providing 37, it is good also as a suction-on state always. Alternatively, if the suction is turned on only at the time of feeding and recording, and the suction is turned off at other times, the cut sheet P or the cut paper P from the support surface of the recording paper support member 13 at the time of feeding and recording. This is more preferable because the static electricity accumulated between the recording paper support member 13 and the cut paper P or the roll paper RP can be further reduced while preventing the roll paper RP from floating.

  Further, in the second embodiment, the fourth embodiment, the fifth embodiment, and the seventh embodiment, the mode in which the roll paper RP is cut by the cutting device 29 has been described as an example, but not limited to the roll paper RP, for example, The cut sheet P may be cut by the cutting device 29 after recording. For example, two A4 size landscape images are recorded side by side in the vertical direction (sub-scanning direction Y) on an A3 size cut sheet P. At that time, after recording the first image, the recorded portion is cut. If a second image is recorded on the unrecorded portion of the cut sheet P, two A4 size photographs can be obtained from one A3 sheet P.
