Summary of the Invention

Problems to be Solved by the Invention

[0004] In a printer such as that of Patent Document 1, when performing borderless recording, the ink that protrudes from the edge of the paper may adhere to the constituent members of the printer. As a result, the ink adhering to the constituent members adheres to the paper that is next fed, and the paper becomes dirty.

[0005] Therefore, an object of the present invention is to provide an image recording apparatus, an image recording system, and a control method for the image recording apparatus that can reduce the adhesion of a coloring material to a recording medium to be fed next and prevent the recording medium from being soiled.

Means for Solving the Problems

[0006] The image recording apparatus of the present invention comprises a recording unit that records an image by attaching a colorant to a recording medium that is fed in the feeding direction, and a control unit, wherein the control unit controls the recording unit to selectively perform bordered recording, in which there is a margin around the edge of the recording medium, and borderless recording, in which there is no margin around the edge, by attaching the colorant to the recording medium so that it extends beyond the edge, wherein when performing bordered recording, the image is recorded on the recording medium based on a first reference position in the width direction of the recording medium, which is a direction intersecting the feeding direction, and when performing borderless recording, the image is recorded on the recording medium based on a second reference position in the width direction that is different from the first reference position.

[0007] Furthermore, the control method for an image recording apparatus of the present invention is a control method for an image recording apparatus comprising a recording unit that records an image by attaching a colorant to a recording medium being fed in the feeding direction, wherein the recording unit is controlled to selectively perform bordered recording, where there is a margin around the edge of the recording medium, and borderless recording, where there is no margin around the edge, by attaching the colorant to the recording medium so that it extends beyond the edge, and when performing bordered recording, the image is recorded on the recording medium based on a first reference position in the width direction of the recording medium, which is a direction intersecting the feeding direction. When performing the aforementioned borderless recording, the image is recorded on the recording medium based on a second reference position that is different from the first reference position in the width direction.

[0008] When performing borderless recording, if the image is recorded on the recording medium based on the same reference position as when performing bordered recording, i.e., the first reference position, the colorant that extends beyond the edge of the recording medium may adhere to the components of the image recording device. As a result, the colorant adheres to the next recording medium being fed, causing it to become dirty. In this regard, the present invention records the image on the recording medium based on a second reference position, which is different from the first reference position, when performing borderless recording. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording device. As a result, it is possible to reduce the adhesion of colorant to the next recording medium being fed, which can cause it to become dirty.

[0009] In a first aspect, the image recording system of the present invention comprises a recording unit that records an image by attaching a colorant to a recording medium being fed in the feeding direction, a notification unit, and a control unit, wherein the control unit controls the recording unit to selectively perform bordered recording, where there is a margin around the edge of the recording medium, and borderless recording, where there is no margin around the edge, by attaching the colorant to the recording medium so that it extends beyond the edge, and when performing bordered recording, the image is recorded on the recording medium based on a first reference position in the width direction of the recording medium, which is a direction intersecting the feeding direction, and when performing borderless recording, the image is recorded on the recording medium based on a second reference position in the width direction that is different from the first reference position, and when performing borderless recording, the notification unit is notified if the recording medium is not positioned at the second reference position.

[0010] Furthermore, in a second aspect, the image recording system of the present invention comprises a recording unit that records an image by attaching a colorant to a recording medium being fed in the feeding direction, a notification unit, and a control unit, wherein the control unit controls the recording unit to selectively perform bordered recording, where there is a margin around the edge of the recording medium, and borderless recording, where there is no margin around the edge, by attaching the colorant to the recording medium so that it extends beyond the edge, and when performing bordered recording, the system records an image on the recording medium based on a first reference position in the width direction of the recording medium, which is a direction intersecting the feeding direction, and when performing borderless recording, the system records an image on the recording medium based on a second reference position in the width direction that is different from the first reference position, and when performing borderless recording, the system causes the notification unit to notify information indicating that the recording medium should be placed at the second reference position.

[0011] When performing borderless recording, if the image is recorded on the recording medium based on the same reference position as when performing bordered recording, i.e., the first reference position, the colorant that extends beyond the edge of the recording medium may adhere to the components of the image recording device. As a result, the colorant adheres to the next recording medium that is fed, causing it to become dirty. In this regard, the present invention records the image on the recording medium based on a second reference position, which is different from the first reference position, when performing borderless recording. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording device. Furthermore, when performing borderless recording on a recording medium, if borderless recording is performed on a recording medium that is not positioned at the second reference position, the colorant that extends beyond the edge of the recording medium is more likely to adhere to the components of the image recording device, but this can be prevented by notification from the notification unit. As a result, it is possible to reduce the adhesion of colorant to the next recording medium that is fed, causing it to become dirty.

[0012] Furthermore, in a third aspect, the image recording system of the present invention comprises a recording unit that records an image by attaching a colorant to a recording medium being fed in the feeding direction, and a control unit, wherein the control unit controls the recording unit to selectively perform bordered recording, in which there is a margin around the edge of the recording medium, and borderless recording, in which there is no margin around the edge, by attaching the colorant to the recording medium so as to extend beyond the edge, and when performing bordered recording, the system records an image on the recording medium based on a first reference position in the width direction of the recording medium, which is a direction intersecting the feeding direction, and when performing borderless recording, the system records an image on the recording medium based on a second reference position in the width direction that is different from the first reference position, and when performing borderless recording, the system performs error processing if it obtains a signal indicating that the recording medium is not at the second reference position.

[0013] When performing borderless recording, if the image is recorded on the recording medium based on the same reference position as when performing bordered recording, i.e., the first reference position, the colorant that extends beyond the edge of the recording medium may adhere to the components of the image recording device. As a result, the colorant adheres to the next recording medium that is fed, causing it to become dirty. In this regard, the present invention records the image on the recording medium based on a second reference position, which is different from the first reference position, when performing borderless recording. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording device. Furthermore, when performing borderless recording on a recording medium, if borderless recording is performed on a recording medium that is not positioned at the second reference position, the colorant that extends beyond the edge of the recording medium is more likely to adhere to the components of the image recording device. However, if borderless recording is not performed and error processing is executed, this can be prevented. As a result, it is possible to reduce the adhesion of colorant to the next recording medium that is fed, causing it to become dirty. [Effects of the Invention]

[0014] According to the image recording apparatus and control method of the present invention, when performing borderless recording, the image is recorded on the recording medium based on a second reference position different from the first reference position. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording apparatus. As a result, it is possible to reduce the adhesion of colorant to the next recording medium being fed and the contamination of the recording medium. Furthermore, according to the image recording system of the first and second aspects of the present invention, when performing borderless recording, the image is recorded on the recording medium based on a second reference position different from the first reference position. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording device. When performing borderless recording on a recording medium, if borderless recording is performed on a recording medium that is not positioned at the second reference position, the colorant that extends beyond the edge of the recording medium is more likely to adhere to the components of the image recording device, but this can be prevented by notification from the notification unit. As a result, it is possible to reduce the adhesion of colorant to the next recording medium being fed and the contamination of the recording medium. Furthermore, according to the third aspect of the present invention, when performing borderless recording, the image is recorded on the recording medium based on a second reference position different from the first reference position. This reduces the adhesion of colorant that extends beyond the edge of the recording medium to the components of the image recording device. When performing borderless recording on a recording medium, if borderless recording is performed on a recording medium that is not positioned at the second reference position, colorant that extends beyond the edge of the recording medium is likely to adhere to the components of the image recording device. However, if borderless recording is not performed and error processing is executed, this can be prevented. As a result, it is possible to reduce the adhesion of colorant to the next recording medium being fed and the contamination of the recording medium. [Brief explanation of the drawing]

[0016] [First Embodiment] A preferred first embodiment of the present invention will be described below.

[0017] <Overall printer configuration> As shown in Figures 1 and 2, the image recording system 100 according to the first embodiment includes a printer 1 and an external device 101 that is communicatively connected to the printer 1. In this embodiment, the external device 101 is a PC having a display unit 102 and a control unit 103 as shown in Figure 6, but it may also be a smartphone or the like. The printer 1 includes a carriage 2, a head 4, a platen 5, transport rollers 6A, 6B, 7A, 7B, a paper setting unit 8 for accommodating recording paper S, two paper feed rollers 9A, 9B, a control unit 80, etc. The printer 1 corresponds to the "image recording device" of the present invention, and the recording paper S corresponds to the "recording medium" of the present invention.

[0018] The carriage 2 is supported by two guide rails 11 and 12, which are spaced apart in the front-rear direction. Guide rails 11 and 12 extend in the left-right direction. The carriage 2 is connected to the carriage motor 86 shown in Figure 6 via a belt or the like (not shown). By driving the carriage motor 86, the carriage 2 can be moved left and right along the guide rails 11 and 12. In this embodiment, the carriage 2, the two guide rails 11 and 12, the belt, and the carriage motor 86 constitute the "movement mechanism" of the present invention.

[0019] In this embodiment, the left direction is a horizontal direction, and the right direction is the opposite direction to the left direction. Also in this embodiment, the front direction is horizontal and perpendicular to the left and right directions, and the rear direction is the opposite direction to the front direction. The right direction corresponds to the "first direction" of the present invention, and the left direction corresponds to the "second direction" of the present invention. Note that the direction including both the left and right directions is the left-right direction, and the direction including both the front and rear directions is the front-back direction. In this embodiment, the left-right direction corresponds to the "width direction of the recording medium" of the present invention. Also in this embodiment, the up direction is perpendicular to the front-back direction and the left-right direction, and the down direction is the opposite direction to the up direction. The direction including both the up and down directions is the up-down direction.

[0020] The print head 4 is mounted on the carriage 2. The print head 4 has a nozzle surface 4A on its underside that has multiple nozzles 10, and ejects ink from the multiple nozzles 10. More specifically, the nozzle surface 4A has a nozzle row 19 in which multiple nozzles 10 are arranged in the front-to-back direction. The print head 4 also has four rows of nozzle rows 19 arranged in the left-to-right direction. The nozzle rows 19 eject black, yellow, cyan, and magenta inks in the order from left to right. The print head 4 is also connected to four ink cartridges (not shown) via four tubes (not shown). The print head 4 is supplied with the four colors of ink from the four ink cartridges. In this embodiment, the print head 4 and carriage 2 correspond to the "recording unit" of the present invention, and the ink corresponds to the "colorant" of the present invention.

[0021] The platen 5 is positioned below the carriage 2 and the head 4. The platen 5 has a facing surface 5A that extends in the left-right and front-back directions and faces the nozzle surface 4A of the head 4. The platen 5 supports the recording paper S from below at the image recording position by the head 4. The recording position is a position where the platen 5 can face the head 4. Regardless of the size of the recording paper S, the recording paper S supported by the platen 5 is within the range in which the platen 5 is positioned in the left-right direction. In this embodiment, the platen 5 corresponds to the "support part" and "constituent member of the image recording device" of the present invention.

[0022] The support of the recording paper S by the platen 5 will now be explained in detail. As shown in Figure 3, a plurality of ribs 16 are arranged on the opposing surface 5A of the platen 5. The plurality of ribs 16 are arranged with spacing in the left-right direction and protrude upward from the opposing surface 5A of the platen 5 toward the nozzle surface 4A of the head 4. Here, the spacing between the plurality of ribs 16 may be equal, or at least some of them may be different. The recording paper S is supported by the platen 5 by contacting the upper ends of at least some of the plurality of ribs 16. Note that since the recording paper S is supported by the platen 5 by contacting the ribs 16 in this way, the recording paper S does not come into contact with the opposing surface 5A of the platen 5.

[0023] Furthermore, the ribs 16 that contact the recording paper S differ depending on the size of the recording paper S in the left-right direction. Specifically, the ribs 16 that contact the recording paper S differ depending on the position of the right edge ER of the recording paper S, which is the rightward leading edge of the recording paper S, and the position of the left edge EL of the recording paper S, which is the leftward leading edge of the recording paper S.

[0024] More specifically, when the recording paper S is, for example, a B5-sized recording paper S1, as shown in Figure 3, the recording paper S1 is supported by the fourth rib 16 from the right edge of the platen 5, the fourth rib 16 from the left edge of the platen 5, and multiple ribs 16 between these two ribs 16. When the recording paper S2 is larger than the recording paper S1, for example, an A4-sized recording paper, the recording paper S2 is supported by the third rib 16 from the right edge of the platen 5, the third rib 16 from the left edge of the platen 5, and multiple ribs 16 between these two ribs 16. The recording paper S1 corresponds to the "first recording medium" of the present invention, and the recording paper S2 corresponds to the "second recording medium" other than the size of the recording paper S1. Note that the size of the recording paper S1 may be A4, B4, or any size arbitrarily set by the user.

[0025] The transport rollers 6A and 6B are positioned behind the carriage 2, head 4, and platen 5. The transport rollers 6A and 6B are rollers whose axial direction is parallel to the left-right direction. Transport roller 6B is positioned below transport roller 6A, so that the recording paper S can be sandwiched between transport rollers 6A and 6B. Transport roller 6B is connected to the transport motor 87 shown in Figure 6 via gears or the like (not shown). When the transport motor 87 is driven, transport roller 6B rotates, and transport roller 6A rotates in response. This allows the recording paper S sandwiched between transport rollers 6A and 6B to be transported forward.

[0026] The transport rollers 7A and 7B are positioned in front of the carriage 2, head 4, and platen 5. The transport rollers 7A and 7B are rollers whose axial direction is parallel to the left-right direction. Transport roller 7B is positioned below transport roller 7A, so that the recording paper S can be sandwiched between transport rollers 7A and 7B. Transport roller 7B is connected to the transport motor 87 shown in Figure 6 via gears or the like (not shown). When the transport motor 87 is driven, transport roller 7B rotates, and transport roller 7A rotates in response. This allows the recording paper S sandwiched between transport rollers 7A and 7B to be transported forward.

[0027] The paper setting unit 8 includes a paper feed tray 8A and a manual feed tray 8B. The paper feed tray 8A is detachably mounted on a tray mounting unit 17 located below the platen 5 of the printer 1. As shown in Figures 1 and 4, the paper feed tray 8A has a paper storage unit 21 with an open top. Multiple sheets of recording paper S are stored in the paper storage unit 21 in a stacked vertically. The paper storage unit 21 is also provided with a first regulating unit 22A and a second regulating unit 22B, as shown in Figures 4 and 5. In this embodiment, the first regulating unit 22A and the second regulating unit 22B correspond to the "pair of regulating units" of the present invention, the first regulating unit 22A corresponds to "one of the regulating units" of the present invention, and the second regulating unit 22B corresponds to "the other regulating unit" of the present invention.

[0028] The manual feed tray 8B is attached to the rear part of the housing 1A of the printer 1. The manual feed tray 8B is configured to be rotatable relative to the housing 1A about a pivot axis 8X at one end. The pivot axis 8X is parallel in the left-right direction. As shown in Figure 1, the manual feed tray 8B is rotatable between a closed position shown by a dashed line and an open position shown by a solid line. In the open position, multiple sheets of recording paper S are placed on the top surface of the manual feed tray 8B, stacked vertically. The manual feed tray 8B is also provided with a first restricting section 22A and a second restricting section 22B.

[0029] In this embodiment, the first restricting unit 22A and the second restricting unit 22B provided on the paper feed tray 8A will be described below, but the first restricting unit 22A and the second restricting unit 22B provided on the manual feed tray 8B can also restrict the recording paper S in the same way as the first restricting unit 22A and the second restricting unit 22B provided on the paper feed tray 8A. Furthermore, the left-right positional relationship between the first restricting unit 22A and the second restricting unit 22B provided on the manual feed tray 8B and the first restricting unit 22A and the second restricting unit 22B provided on the paper feed tray 8A is the same.

[0030] As shown in Figure 5, the first regulating section 22A has a regulating section body 22A1 and a detachable section 22A2. The regulating section body 22A1 is a plate-shaped member extending in the front-rear and up-down directions. The detachable section 22A2 is configured to be detachably attached to the regulating section body 22A1 and has thickness in the left-right direction. As shown in Figure 5(b), the detachable section 22A2 has a groove 22A3 that opens downward. The groove 22A3 extends in the front-rear direction and is shaped to fit with the regulating section body 22A1. The detachable section 22A2 is configured to be attached to the regulating section body 22A1 from above, making it possible to easily attach the detachable section 22A2 to the regulating section body 22A1.

[0031] As shown in Figures 4 and 5, the first regulating section 22A is designed to regulate and position the right edge ER of the recording paper S stored in the paper storage section 21 by contacting the right edge ER of the recording paper S in the left-right direction, with the regulating section body 22A1 or the attachment / detachment section 22A2 being the regulating section body 22A1 or the attachment / detachment section 22A2 being the attachment / detachment section. Specifically, the regulating section body 22A1 has a body contact surface 22A5 that can contact the right edge ER of the recording paper S. The body contact surface 22A5 is the left side of the regulating section body 22A1. The attachment / detachment section 22A2 also has a contact surface 22A6 that can contact the right edge ER of the recording paper S. The contact surface 22A6 is the left side of the attachment / detachment section 22A2.

[0032] The second restricting section 22B is located to the left of the first restricting section 22A and extends in the front-to-back direction. The second restricting section 22B has a shape symmetrical to the main restricting section body 22A1 in the left-to-right direction. The second restricting section 22B contacts the left edge EL of the recording paper S stored in the paper storage section 21 to restrict and position the position of the left edge EL of the recording paper S in the left-to-right direction. In other words, the second restricting section 22B has a contact surface 22B1 that can contact the left edge EL of the recording paper S. The contact surface 22B1 is the right side of the second restricting section 22B. Furthermore, the first restricting section 22A and the second restricting section 22B are movable symmetrically to the left and right with respect to the central axis C1 extending in the front-to-back direction, in accordance with the left-to-right size of the recording paper S stored in the paper storage section 21.

[0033] More specifically, the regulating body 22A1 of the first regulating section 22A is connected to the rack gear 26A. The rack gear 26A is connected to the front end of the regulating body 22A1 and extends to the left from the connection point with the regulating body 22A1. Furthermore, the first regulating section 22A and the rack gear 26A are movable to the left and right along the guide groove 27A which extends in the left-right direction.

[0034] The second restrictor 22B is connected to the rack gear 26B. The rack gear 26B is connected to the rear end of the second restrictor 22B and extends to the right from the connection point with the second restrictor 22B. The second restrictor 22B and the rack gear 26B are movable to the left and right along the guide groove 27B which extends in the left-right direction.

[0035] Furthermore, a pinion gear 28 is positioned between the rack gear 26A and the rack gear 26B in the front-rear direction, and the pinion gear 28 meshes with the rack gears 26A and 26B.

[0036] With the above configuration, when the user moves the regulating unit body 22A1 to the right, the rack gear 26A moves to the right together with the regulating unit body 22A1, and the pinion gear 28 rotates. Due to the rotation of the pinion gear 28, the rack gear 26B moves to the left, and the second regulating unit 22B moves to the left together with the rack gear 26B. When the user moves the regulating unit body 22A1 to the left, the rack gear 26A moves to the left together with the regulating unit body 22A1, and the pinion gear 28 rotates. Due to the rotation of the pinion gear 28, the rack gear 26B moves to the right, and the second regulating unit 22B moves to the right together with the rack gear 26B. When the user moves the second regulating unit 22B to the right, the rack gear 26B moves to the right together with the second regulating unit 22B, and the pinion gear 28 rotates. As the pinion gear 28 rotates, the rack gear 26A moves to the left, and the regulating body 22A1 moves to the left together with the rack gear 26A. When the user moves the second regulating body 22B to the left, the rack gear 26B moves to the left together with the second regulating body 22B, and the pinion gear 28 rotates. As the pinion gear 28 rotates, the rack gear 26A moves to the right, and the regulating body 22A1 moves to the right together with the rack gear 26A. Furthermore, in the movements described above, the magnitude of the movement distance of the regulating body 22A1 and the magnitude of the movement distance of the second regulating body 22B are the same. Thus, in this embodiment, the regulating body 22A1 and the second regulating body 22B can move symmetrically to the left and right with respect to the central axis C1. The central axis C1 passes through the center in the left-right direction between the regulating body 22A1 and the second regulating body 22B. Furthermore, the manual feed tray 8B is also provided with rack gears 26A, 26B, guide grooves 27A, 27B, and a pinion gear 28, and the regulating unit body 22A1 and the second regulating unit 22B provided on the manual feed tray 8B can move in the same way as the regulating unit body 22A1 and the second regulating unit 22B provided on the paper feed tray 8A.

[0037] Furthermore, since the regulating unit body 22A1 and the second regulating unit 22B are movable symmetrically to the left and right with respect to the central axis C1, as shown in Figure 4, the recording paper S, which is stored in the paper storage unit 21 and positioned by the regulating unit body 22A1 and the second regulating unit 22B, is positioned such that, regardless of its size, the center position between the left end EL and the right end ER in the left-right direction coincides with the central axis C1. In this embodiment, the central axis C1 corresponds to the "first reference position" of the present invention. In the manual feed tray 8B as well, the recording paper S, which is placed on the upper surface of the manual feed tray 8B and positioned by the regulating unit body 22A1 and the second regulating unit 22B, is positioned such that, regardless of its size, the center position between the left end EL and the right end ER in the left-right direction coincides with the central axis C1. The left-right position of the central axis C1 is in the same positional relationship in both the paper feed tray 8A and the manual feed tray 8B.

[0038] On the other hand, as shown in Figure 5, the recording paper S, which is positioned by the first regulating section 22A and the second regulating section 22B, with the attachment / detachment section 22A2 mounted on the regulating section body 22A1, is positioned such that, regardless of its size, the positions of the centers of the left end EL and the right end ER in the left and right directions coincide with an axis C2 parallel to the central axis C1, which is shifted a predetermined distance to the left from the central axis C1. The axis C2 passes through the center in the left-right direction between the contact surface 22A6 of the first regulating section 22A, with the attachment / detachment section 22A2 mounted on the regulating section body 22A1, and the contact surface 22B1 of the second regulating section 22B. The predetermined distance here is half the left-right separation distance between the main body contact surface 22A5 and the contact surface 22A6. In this embodiment, axis C2 corresponds to the "second reference position" of the present invention. The attachment / detachment section 22A2 is positioned so that the left-right center of the recording paper S coincides with axis C2, which is the second reference position. Furthermore, the left-right position of axis C2 is the same in both the paper feed tray 8A and the manual feed tray 8B.

[0039] In the printer 1 of this embodiment, bordered or borderless recording can be performed on the recording paper S1. When performing bordered or borderless recording, the position of the recording paper S1 is selectively restricted by a first restricting unit 22A, in which a detachable part 22A2 is attached to the restricting unit body 22A1, or by a first restricting unit 22A from which the detachable part 22A2 has been removed. When performing bordered recording, the recording paper S1 is positioned by a first restricting unit 22A from which the detachable part 22A2 has been removed and a second restricting unit 22B. As shown in Figure 4, when restricting the position of the recording paper S1, the first restricting unit 22A and the second restricting unit 22B take a first restricting position in which the main body contact surface 22A5 of the restricting unit body 22A1 is in contact with the right edge ER of the recording paper S1, and the contact surface 22B1 of the second restricting unit 22B is in contact with the left edge EL of the recording paper S1. In this embodiment, the rightmost edge ER of the recording paper S1 corresponds to the "first edge" of the present invention.

[0040] On the other hand, when performing borderless recording, the recording paper S1 is positioned by the first regulating unit 22A and the second regulating unit 22B, which have a detachable unit 22A2 attached to the regulating unit body 22A1. As shown in Figure 5, when regulating the position of the recording paper S1, the first regulating unit 22A and the second regulating unit 22B take a second regulating position in which the contact surface 22A6 of the detachable unit 22A2 contacts the right edge ER of the recording paper S1, and the contact surface 22B1 of the second regulating unit 22B contacts the left edge EL of the recording paper S1. The first regulating position and the second regulating position are different from each other in the left-right direction.

[0041] In the printer 1 of this embodiment, whether recording with a border or borderless recording is performed on the recording paper S2, the position of the recording paper S2 is restricted by the first restricting unit 22A and the second restricting unit 22B, which are formed by removing the attachment / detachment unit 22A2 from the restricting unit body 22A1. In other words, when restricting the position of the recording paper S2, the first restricting unit 22A and the second restricting unit 22B take a first restricting position in which the body contact surface 22A5 of the restricting unit body 22A1 contacts the right edge ER of the recording paper S2, and the contact surface 22B1 of the second restricting unit 22B contacts the left edge EL of the recording paper S2. In this embodiment, the right edge ER of the recording paper S2 corresponds to the "second edge" of the present invention.

[0042] In this way, the recording paper S restricted by the first restricting section 22A and the second restricting section 22B, which are in the first restricting position, has its left-right center coincide with the central axis C1. On the other hand, the recording paper S restricted by the first restricting section 22A and the second restricting section 22B, which are in the second restricting position, has its left-right center coincide with axis C2.

[0043] Furthermore, as shown in Figures 4 and 5, the first regulating unit 22A is provided with an attachment sensor 22A4 that detects whether or not the attachment / detachment unit 22A2 is attached to the regulating unit body 22A1. In this embodiment, the attachment sensor 22A4 is a mechanical switch, but any sensor capable of detecting whether or not the attachment / detachment unit 22A2 is attached to the regulating unit body 22A1 may be used, such as an optical sensor or a magnetic sensor. In this embodiment, the attachment sensor 22A4 corresponds to the "detection unit" of the present invention. As a modified example, a sensor that detects the position of the recording paper S regulated by the first regulating unit 22A and the second regulating unit 22B may be provided in place of the attachment sensor 22A4, and the regulating unit body 22A1 may be detected based on the position of the recording paper S detected by the sensor.

[0044] The mounting sensor 22A4 outputs a signal to the control unit 80 indicating the mounting status when the detachable part 22A2 is mounted on the regulating unit body 22A1, and a signal indicating the non-mounted status when the detachable part 22A2 is not mounted on the regulating unit body 22A1.

[0045] As shown in Figure 1, the paper feed roller 9A is located on the tray mounting section 17. The paper feed roller 9A is biased downward by a spring (not shown) and pressed against the recording paper S stored in the paper storage section 21 of the mounted paper feed tray 8A. The paper feed roller 9B is located near the rotation axis 8X of the manual feed tray 8B. The paper feed roller 9B is also biased downward by a spring (not shown) and pressed against the recording paper S placed on the upper surface of the manual feed tray 8B. These paper feed rollers 9A and 9B are connected to the paper feed motors 88A and 88B shown in Figure 6 via gears (not shown). When the paper feed motor 88A is driven, the paper feed roller 9A rotates. When the paper feed motor 88B is driven, the paper feed roller 9B rotates. When the paper feed roller 9A rotates, the single recording paper S located furthest upward among the multiple recording papers S stored in the paper storage section 21 is fed backward. The recording paper S, which is fed backward by the paper feed roller 9A, is transported along the paper feed path 18 located behind the paper feed roller 9A. As shown by arrow A in Figure 1, the transport direction changes from backward to forward, and the paper is supplied to the transport rollers 6A and 6B.

[0046] When the paper feed roller 9B rotates, the uppermost sheet of recording paper S among the multiple sheets of recording paper S placed on the upper surface of the manual feed tray 8B is fed forward. The recording paper S fed forward by the paper feed roller 9B merges with the paper feed path 18 midway through and is transported along the paper feed path 18, and supplied to the transport rollers 6A and 6B. The transport rollers 6A and 6B then transport the supplied recording paper S forward.

[0047] In this embodiment, the paper setting unit 8, paper feed rollers 9A, 9B, paper feed path 18, and transport rollers 6A, 6B correspond to the "feeding unit" of the present invention. The direction of arrow A, in which the recording paper S is transported from the paper setting unit 8 to the platen 5 by this feeding unit, corresponds to the "feeding direction" of the present invention. Furthermore, the direction of arrow A is perpendicular to the left-right direction, and the center of the recording paper S transported from the paper setting unit 8 to the platen 5 is positioned on the central axis C1 or axis C2. As a result, by feeding the recording paper S1 or recording paper S2 in an appropriate position in the paper setting unit 8, it is possible to reduce the amount of ink that spills over the edge of the recording paper S and adheres to the upper surface of the rib 16 of the platen 5, as will be described later.

[0048] Furthermore, as shown in Figure 2, the carriage 2 is provided with a media sensor 89 to detect the recording paper S being transported by the transport rollers 6A and 6B. The media sensor 89 has a light-emitting element 89A and a light-receiving element 89B. The light-emitting element 89A and the light-receiving element 89B face the platen 5. The light-emitting element 89A irradiates light toward the platen 5. The light-receiving element 89B outputs a signal corresponding to the amount of light received. In this embodiment, the media sensor 89 corresponds to the "edge detection unit" of the present invention.

[0049] Here, the recording paper S is white, while the platen 5 is black. When the recording paper S is not facing the media sensor 89 of the platen 5, the light emitted from the light-emitting element 89A hits the black platen 5 and is hardly reflected. Therefore, in this state, the amount of light received by the light-receiving element 89B is below the threshold. When the recording paper S is facing the media sensor 89 of the platen 5, the light emitted from the light-emitting element 89A hits the white recording paper S and is reflected. Therefore, in this state, the amount of light received by the light-receiving element 89B is above the threshold.

[0050] This allows the system to detect that the recording paper S being transported by the transport rollers 6A and 6B has reached the position on the platen 5 facing the media sensor 89, based on the change in the amount of light received by the light receiving element 89B from below a threshold to above a threshold, while the carriage 2 is positioned so that the media sensor 89 is facing the portion of the platen 5 that overlaps with the recording paper S.

[0051] <Electrical configuration of the image recording system> Next, the electrical configuration of the image recording system 100 will be described. As shown in Figure 6, the image recording system 100 consists of a control unit 80 of the printer 1 and a control unit 103 of the external device 101, which are connected to each other in a manner that allows them to communicate with one another. These control units 80 and 103 consist of a CPU, ROM, RAM, memory, ASIC, etc. CPU is an abbreviation for Central Processing Unit. ROM is an abbreviation for Read Only Memory. RAM is an abbreviation for Random Access Memory. ASIC is an abbreviation for Application Specific Integrated Circuit. The control unit 80 controls the operation of the carriage motor 86, head 4, transport motor 87, paper feed motors 88A, 88B, light-emitting element 89A of the media sensor 89, etc. The control unit 80 also receives signals from the mounting sensor 22A4 and the light-receiving element 89B of the media sensor 89. The control unit 103 controls the operation of the display unit 102. In this embodiment, the display unit 102 corresponds to the "notification unit" of the present invention.

[0052] Furthermore, the control units 80 and 103 may perform various processing solely with the CPU, solely with the ASIC, or collaboratively with the CPU and ASIC. Also, the control units 80 and 103 may be performed by a single CPU alone, or by multiple CPUs sharing the processing. Similarly, the control units 80 and 103 may be performed by a single ASIC alone, or by multiple ASICs sharing the processing.

[0053] <Control during recording> Next, the processing performed by the control units 80 and 103 when recording an image onto the recording paper S in the image recording system 100 will be described.

[0054] The image recording system 100 is capable of both bordered and borderless recording of images onto recording paper S by the printer 1. Bordered recording is a recording operation in which an image is recorded such that margins M are created on the left, right, front, and back edges of the recording paper S, as shown in Figure 7(a) for example, when recording image G1 onto the recording paper S. Borderless recording is a recording operation in which an image is recorded such that no margins are created on the left, right, front, and back edges of the recording paper S, as shown in Figure 7(b) for example, when recording image G2 onto the recording paper S.

[0055] In the image recording system 100, the control units 80 and 103 perform processing according to the flowchart in Figure 7(c) to record on the recording paper S. When the control unit 80 receives a recording command from the control unit 103 instructing it to record an image on the recording paper S, it starts the flowchart in Figure 7(c). In this embodiment, the recording command is transmitted to the control unit 80 based on the user's operation of the external device 101. The recording command may also be transmitted to the control unit 80 based on the user's operation of an operation unit (not shown) of the printer 1. The recording command also includes image data of the image to be recorded, paper size information indicating the size of the recording paper S, recording type information indicating whether to perform bordered or borderless recording, and transport information indicating whether to transport the recording paper S placed in the paper feed tray 8A or the manual feed tray 8B.

[0056] When sending a recording command from the external device 101 to the control unit 80 of the printer 1, as shown in Figure 8(a), the user selects the recording paper size displayed on the display unit 102 of the external device 101, checks the checkbox if borderless recording is to be performed, and then presses the OK button to send the command. Figure 8(a) shows a screen where B5 size is selected as the recording paper size and borderless recording is to be performed, but other recording paper sizes such as A4 may also be used, or the user may uncheck the checkbox and select bordered recording.

[0057] In the external device 101 of this embodiment, when the checkbox for borderless recording is checked, the control unit 103 controls the display unit 102 to display the message "Attach the attachment unit and attach the B5 size recording paper" as information to restrict the recording paper S1 at the second restriction position using the first restriction unit 22A and the second restriction unit 22B, as shown in Figure 8(b). As a result, with the user attaching the attachment unit 22A2 to the restriction unit body 22A1, the first restriction unit 22A and the second restriction unit 22B take the second restriction position and position the recording paper S1. At this time, the left-right centers of the first restriction unit 22A and the second restriction unit 22B are located on axis C2. Therefore, the left-right center of the recording paper S1 also coincides with axis C2. The control unit 103 may also notify the display unit 102 of information other than the above message as information to position the center of the recording paper S1 on axis C2 using the first regulating unit 22A and the second regulating unit 22B.

[0058] In the printer 1 of this embodiment, recording is performed on recording paper S2 restricted by the first restriction unit 22A and the second restriction unit 22B, which take the first restriction position, in both bordered and borderless recording modes. At this time, the left-right centers of the first restriction unit 22A and the second restriction unit 22B are located on the central axis C1. Therefore, the left-right center of the recording paper S2 also coincides with the central axis C1. Consequently, even if A4 size is selected for the recording paper S2 and the checkbox for borderless recording is checked, the control unit 103 does not perform control to notify the display unit 102 of information indicating that the center of the recording paper S2 should be positioned on axis C2. Because the control unit 103 does not perform such notification control, the control of the control unit 103 becomes easier.

[0059] To explain the flowchart in Figure 7(c) in detail, the control unit 80 determines whether or not to perform borderless recording based on the recording type information (S101). If the control unit 80 determines in S101 to perform bordered recording and not borderless recording (S101: NO), it proceeds to the paper feeding process in S105.

[0060] If the control unit 80 determines in S101 that borderless recording should be performed (S101:YES), it determines whether the paper size is B5 size based on the paper size information (S102). If the control unit 80 determines in S102 that the paper is not B5 size (S102:NO), it proceeds to the paper feeding process in S105. On the other hand, if the control unit 80 determines in S102 that the paper is B5 size (S102:YES), it determines whether the attachment / detachment unit 22A2 is attached based on the signal from the attachment sensor 22A4 (S103). In other words, the control unit 80 checks whether the center of the recording paper S1 is on axis C2.

[0061] If the detachable part 22A2 is not attached to the regulating unit body 22A1, the center of the recording paper S1 will not be positioned on axis C2. Therefore, in S103, if the signal from the mounting sensor 22A4 indicates that it is not attached, the control unit 80 determines that the detachable part 22A2 is not attached (S103: NO). In other words, the control unit 80 can confirm whether the center of the recording paper S1 is on axis C2 based on whether or not the detachable part 22A2 is attached to the regulating unit body 22A1.

[0062] Next, as shown in Figure 8(b), the control unit 80 outputs a control signal to the control unit 103 to display the message "Attach the attachment unit and restrict the B5 size recording paper" on the display unit 102, and the control unit 103 controls the display unit 102 based on the control signal to display the above message (S104). In this way, the user is informed that the first restriction unit 22A and the second restriction unit 22B should position the center of the recording paper S1 on axis C2. In this embodiment, the signal indicating the non-attached state corresponds to the "signal indicating that the recording medium is not in the second reference position" of the present invention, and the notification process in S104 corresponds to the "error processing" of the present invention. After S104, the process returns to S103, and the process in S103 is executed. In S103, the control unit 80 determines that the attachment unit 22A2 has been attached if the signal from the attachment sensor 22A4 is a signal indicating the attached state (S103: YES), and executes the paper feeding process (S105).

[0063] In the paper feeding process of S105, the control unit 80 controls the paper feed motor 88A or paper feed motor 88B based on the transport information to supply recording paper S from the paper setting unit 8, and controls the transport motor 87 to transport the supplied recording paper S to the transport rollers 6A and 6B to a position detected by the media sensor 89.

[0064] Next, the control unit 80 determines whether or not it is a borderless recording, similar to S101 (S106). If it is a bordered recording (S106: NO), the control unit 80 executes the first image data generation process (S107). In the first image data generation process in S107, the control unit 80 generates image data of image G1 in Figure 7(a), which is an enlarged or reduced version of the image indicated by the image data included in the recording command. Then, the process proceeds to the recording process in S109.

[0065] If borderless recording is required (S106: YES), the control unit 80 executes a second image data generation process (S108). In the second image data generation process in S108, the control unit 80 generates image data of image G3, as shown in Figure 9, which extends beyond the recording paper S in the left, right, front, and rear directions by enlarging or reducing the image indicated by the image data included in the recording command. At this time, the control unit 80 generates image data of image G3 by enlarging or reducing the image indicated by the image data included in the recording command by a predetermined magnification corresponding to the size of the recording paper S. The rightward overhang distance WR from the right edge ER of the recording paper S and the leftward overhang distance WL from the left edge EL of the recording paper S are both the same. Then, the process proceeds to the recording process in S109.

[0066] In the recording process of S109, the control unit 80 repeatedly performs a recording path in which ink is applied to the recording paper S by controlling the carriage motor 86 to move the carriage 2 to the left or to the right, and controlling the head 4 to eject ink from multiple nozzles 10 toward the recording paper S, and a transport operation in which the transport motor 87 is controlled to transport the recording paper S toward the forward direction by the transport rollers 6A, 6B, 7A, 7B, thereby recording an image onto the recording paper S.

[0067] In this case, if image data is generated in the first image data generation process in S107, the control unit 80 generates ejection data to cause the head 4 to eject ink from multiple nozzles 10 based on the image data generated in S107. Similarly, if image data is generated in the second image data generation process in S108, the control unit 80 also generates ejection data to cause the head 4 to eject ink from multiple nozzles 10 based on the image data generated in S108. Then, when the recording pass is performed, the control unit 80 controls the head 4 based on the ejection data to eject ink from the multiple nozzles 10.

[0068] In step S109, the control unit 80 determines the image recording position W1 when performing borderless recording on recording paper S1 based on axis C2, as shown in Figure 10(b), and determines the image recording positions W2 to W4 when performing bordered recording on recording paper S1, when performing bordered recording on recording paper S2, and when performing borderless recording on recording paper S2, as shown in Figure 3(b), based on the central axis C1. Recording positions W1 and W4 are the ranges in which ink is ejected based on image G3, and recording positions W2 and W3 indicate the ranges in which ink is ejected based on image G1.

[0069] The control unit 80 predetermines the recording position W1 as a position where the horizontal center of image G3 coincides with the reference central axis C1. Then, when performing borderless recording on recording paper S1, the control unit 80 redetermines the predetermined recording position W1 by shifting it based on the amount by which axis C2 is shifted horizontally relative to the reference central axis C1. As a result, when performing borderless recording on recording paper S1, ink is ejected from the head 4 onto the recording paper S1 at a timing such that the horizontal center of image G3 coincides with axis C2. On the other hand, in any case of performing bordered recording on recording paper S1, bordered recording on recording paper S2, or borderless recording on recording paper S2, the control unit 80 predetermines the recording positions W2 to W4 as positions where the horizontal centers of images G1 and G3 coincide with the reference central axis C1. As a result, ink is ejected from the head 4 onto the recording paper S1 and S2 at a timing such that the horizontal center of image G1 or image G3 coincides with the central axis C1.

[0070] Here, we will describe the state in which the recording sheets S1 and S2, which are restricted by the first restricting section 22A and the second restricting section 22B that take the first restricting position, are transported from the paper setting section 8 onto the platen 5. In both cases, the center of the recording sheet S restricted by the first restricting section 22A and the second restricting section 22B that take the first restricting position is positioned on the central axis C1 on the platen 5. As shown in Figure 3, in the state in which the recording sheet S1 is transported onto the platen 5, the distance to the right between the right end ER of the recording sheet S1 and the rib 16A closest to the right of the right end ER, and the distance to the left between the left end EL of the recording sheet S1 and the rib 16B closest to the left of the left end EL, are both distance L1. In this embodiment, distance L1 corresponds to the "first distance" and "fourth distance" of the present invention. Here, the distance to the right of the right edge ER of the recording sheet S1 and the rib 16A closest to the right of the right edge ER, and the distance to the left of the left edge EL of the recording sheet S1 and the rib 16B closest to the left of the left edge EL, do not necessarily have to be the same. If they are not the same, the shorter distance should be designated as L1.

[0071] On the other hand, when the recording paper S2 is transported on the platen 5, the distance to the right between the right edge ER of the recording paper S2 and the rib 16C closest to the right of the right edge ER, and the distance to the left between the left edge EL of the recording paper S2 and the rib 16D closest to the left of the left edge EL, are both distance L2. Distance L2 is greater than distance L1 and the overhang distances WR and WL. On the other hand, distance L1 is less than the overhang distances WR and WL. In this embodiment, distance L2 corresponds to the "second distance" of the present invention. Here, the distance to the right between the right edge ER of the recording paper S2 and the rib 16C closest to the right of the right edge ER, and the distance to the left between the left edge EL of the recording paper S2 and the rib 16D closest to the left of the left edge EL, do not necessarily have to be the same. If they are not the same, the shorter distance may be used as L2.

[0072] As explained above, when borderless recording is performed on the recording paper S2, which is restricted by the first restriction section 22A and the second restriction section 22B that take the first restriction position, the upper surfaces of the ribs 16C and 16D are in a position where almost no ink from overflowing from the recording paper S2 adheres to them. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur. Accordingly, the recording paper S2 may be restricted by the first restriction section 22A and the second restriction section 22B that take the first restriction position, regardless of whether bordered or borderless recording is performed. On the other hand, when borderless recording is performed on the recording paper S1, which is restricted by the first restriction section 22A and the second restriction section 22B that take the first restriction position, the upper surfaces of the ribs 16A and 16B are in a position where ink from overflowing from the recording paper S1 is likely to adhere to them. Therefore, a problem is likely to occur where the ink adhering to the upper surface of the rib 16 transfers to the next feeding of recording paper S, causing the recording paper S to become soiled.

[0073] Next, we will describe the state in which the recording paper S1, restricted by the first restricting section 22A and the second restricting section 22B which take the second restricting position, is transported from the paper setting section 8 onto the platen 5. As shown in Figure 10, the recording paper S1 transported onto the platen 5 has its left-right center positioned on axis C2 and is supported by the fourth rib 16 from the right end of the platen 5, the third rib 16 from the left end of the platen 5, and multiple ribs 16 between these two ribs 16. The distance to the right between the right end ER of the recording paper S1 and the rib 16A closest to the right of the right end ER, and the distance to the left between the left end EL of the recording paper S1 and the rib 16D closest to the left of the left end EL, are both distance L3. Distance L3 is greater than distance L1 and the overhang distances WR and WL. In this embodiment, distance L3 corresponds to the "third distance" and "fifth distance" of the present invention. Here, the distance to the right of the right edge ER of the recording sheet S1 and the rib 16A closest to the right of the right edge ER, and the distance to the left of the left edge EL of the recording sheet S1 and the rib 16D closest to the left of the left edge EL, do not necessarily have to be the same. If they are not the same, the shorter distance should be designated as L3.

[0074] As explained above, when borderless recording is performed on the recording paper S1, which is restricted by the first restriction unit 22A and the second restriction unit 22B that take the second restriction position, the upper surfaces of the ribs 16A and 16D are in a position where almost no ink that has spilled from the recording paper S1 adheres to them. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is unlikely to occur.

[0075] When the recording process in S109 is completed, the flow ends. In this way, the recording of the image onto the recording paper S in the image recording system 100 is completed.

[0076] As described above, in the image recording system 100 of this embodiment, when performing borderless recording, if the image is recorded on the recording paper S1 based on the same reference position as when performing bordered recording, i.e., the central axis C1, ink that spills over the edge of the recording paper S1 may adhere to the upper surface of the rib 16 of the platen 5 of the printer 1. As a result, ink adheres to the next feeding of recording paper S, and the recording paper S becomes dirty. In this regard, in the present invention, when performing borderless recording, the image is recorded on the recording paper S1 based on an axis C2 different from the central axis C1. This reduces the amount of ink that spills over the edge of the recording paper S1 adhering to the upper surface of the rib 16. As a result, it is possible to reduce the amount of ink that spills over the edge of the recording paper S and becomes dirty.

[0077] Furthermore, in S109, the control unit 80 records the image based on the central axis C1, whether bordered or borderless recording is performed on the recording paper S2. This simplifies the control by the control unit 80.

[0078] The first restricting section 22A and the second restricting section 22B are configured such that when the first restricting section 22A is moved to one side in the left-right direction, the second restricting section 22B is moved to the other side by the same amount. This configuration allows the left-right centers of the first restricting section 22A and the second restricting section 22B to be selectively positioned on either the central axis C1 or axis C2 when the recording paper S is sandwiched between them in the left-right direction. Even if the configuration allows the second restricting section 22B to be moved to the other side by the same amount as when the first restricting section 22A is moved to one side in the left-right direction, if the left-right centers can only be positioned on one of the central axes C1 and axis C2, then to position the center on the other axis, it is necessary to position the recording paper S without using either restricting section, making it extremely difficult to accurately transport the recording paper S along arrow A. However, in this configuration, the left-right centers of the first regulating section 22A and the second regulating section 22B can be selectively positioned on either the central axis C1 or axis C2, thereby improving the accuracy of the left-right transport position of the recording paper S.

[0079] When performing borderless recording on the recording paper S1, the control unit 80 determines the predetermined recording position W1 to be on an axis C2 that is offset to the left or right with respect to the reference central axis C1. This makes it easy to determine the recording position W1 when performing borderless recording on the recording paper S1.

[0080] In S103, the control unit 80 checks whether the center of the recording paper S1 is on axis C2. This makes it possible to more reliably reduce the amount of ink that spills over the edge of the recording paper S1 and adheres to the upper surface of the rib 16.

[0081] In S103, if the control unit 80 receives a signal from the mounting sensor 22A4 indicating that it is not mounted (S103: NO), it executes the notification process in S104. When performing borderless recording on the recording paper S1, if borderless recording is performed on a recording paper S1 whose center is not aligned with axis C2, ink that spills over the edge of the recording paper S1 is likely to adhere to the upper surface of the rib 16 of the platen 5. However, the notification from the display unit 102 allows the user to know that they must change the position of the recording paper S1, thereby preventing ink from adhering to the upper surface of the rib 16. In other words, the adhesion of ink that spills over the edge of the recording paper S1 to the upper surface of the rib 16 can be reduced more reliably. As a result, it is possible to reduce the amount of ink that adheres to the next feeding of recording paper S and stains the recording paper S.

[0082] When performing borderless recording on the recording paper S1, the control unit 103 uses the first regulating unit 22A and the second regulating unit 22B to inform the display unit 102 of information to position the center of the recording paper S1 on axis C2. This also prevents ink that has spilled over the edge of the recording paper S1 from easily adhering to the upper surface of the rib 16 of the platen 5. As a result, it is possible to reduce the amount of ink that adheres to the next feeding of recording paper S and stains the recording paper S.

[0083] [Second Embodiment] Next, with reference to Figures 11 and 12, an image recording system according to a second embodiment of the present invention will be described. The image recording system in this embodiment is the same as that of the first embodiment, except that the configuration of the platen 5 is different from that of the first embodiment. In configurations similar to those in the first embodiment, the same reference numerals are used and their descriptions are omitted.

[0084] In this embodiment, the platen 5 does not have multiple ribs 16, but has three recesses 5B1 to 5B3 on the opposing surface 5A. In this embodiment, the opposing surface 5A supports the recording paper S from below.

[0085] Each recess 5B1 to 5B3 extends in the front-to-back direction and opens upward. The length of each recess 5B1 to 5B3 in the front-to-back direction is longer than the nozzle surface 4A of the head 4. Furthermore, the front end of each recess 5B1 to 5B3 is located further forward than the front end of the nozzle surface 4A, and the rear end of each recess 5B1 to 5B3 is located further back than the rear end of the nozzle surface 4A. A foam 5C that absorbs ink is provided on the bottom surface of each recess 5B1 to 5B3. The foam 5C is made of a porous material such as a sponge. In this embodiment, the recesses 5B1 to 5B3 correspond to the "receiving region" of the present invention, and the region of the opposing surface 5A excluding the recesses 5B1 to 5B3 corresponds to the "support region" of the present invention.

[0086] The three recesses 5B1 to 5B3 are spaced apart from each other in the left-right direction. The three recesses 5B1 to 5B3 and the opposing surface 5A are arranged side by side in the left-right direction. Of the three recesses 5B1 to 5B3, the rightmost recess 5B1 and the leftmost recess 5B2 are positioned to overlap with the right edge ER and left edge EL of the recording paper S2 when the recording paper S2, which is restricted by the first restricting section 22A and the second restricting section 22B that take the first restricting position, is transported from the paper setting section 8 onto the platen 5, as shown in Figure 11. The left-right center of the recording paper S2 is located on the central axis C1.

[0087] More specifically, the right edge ER of the recording paper S2 is positioned on the recess 5B1, and the distance between the right edge ER and the right edge of the recess 5B1, and the left edge EL of the recording paper S2 is positioned on the recess 5B2, and the distance between the left edge EL and the left edge of the recess 5B2, are both distance L4. Here, distance L4 is the same distance as distance L2 in the first embodiment. Therefore, even if borderless recording is performed on the recording paper S2, all ink that spills to the right from the right edge ER is received by the recess 5B1, and all ink that spills to the left from the left edge EL is received by the recess 5B2. As a result, the ink does not adhere to the opposing surface 5A.

[0088] On the other hand, recesses 5B1 and 5B2 are positioned apart to the right and left, respectively, when the recording paper S1, which is restricted by the first restricting section 22A and the second restricting section 22B that take the first restricting position, is transported from the paper setting section 8 onto the platen 5, and does not overlap with the right edge ER and the left edge EL of the recording paper S1. The left-right center of the recording paper S1 is positioned on the central axis C1.

[0089] More specifically, the distance between the right edge ER of the recording paper S1 and the left edge of the recess 5B1, and the distance between the left edge EL of the recording paper S1 and the right edge of the recess 5B2, are both distance L5. In this way, the recording paper S1, which is restricted by the first restricting section 22A and the second restricting section 22B that take the first restricting position, has its right edge ER and left edge EL separated from the recesses 5B1 and 5B2 by a distance of L5. Therefore, when borderless recording is performed on the recording paper S1, ink that spills to the right from the right edge ER and ink that spills to the left from the left edge EL adheres to the opposing surface 5A. In this embodiment, distance L5 corresponds to the "first predetermined distance" of the present invention.

[0090] Of the three recesses 5B1 to 5B3, recess 5B3, located between recess 5B1 and recess 5B2 in the left-right direction, overlaps entirely in the vertical direction with the recording paper S1 and S2 restricted by the first restricting section 22A and the second restricting section 22B, which assume the first restricting position, as shown in Figure 11(a). However, as shown in Figure 12, recess 5B3 is positioned to overlap with the right edge ER of the recording paper S1 when the recording paper S1 restricted by the first restricting section 22A and the second restricting section 22B, which assume the second restricting position, is transported from the paper setting section 8 onto the platen 5. The left-right center of the recording paper S1 is located on axis C2.

[0091] More specifically, the right edge ER of the recording paper S1 is positioned on the recess 5B3, and the separation distance between the right edge ER and the right edge of the recess 5B3 is distance L4. The left edge EL of the recording paper S1 is positioned on the recess 5B2, and the separation distance between the left edge EL and the left edge of the recess 5B1 is distance L6, which is greater than distance L4. Therefore, even if borderless recording is performed on the recording paper S1, all ink that spills to the right from the right edge ER is received by the recess 5B3, and all ink that spills to the left from the left edge EL is received by the recess 5B2. As a result, the ink does not adhere to the opposing surface 5A. In this embodiment, distance L4 corresponds to the "second predetermined distance" of the present invention.

[0092] Thus, in the platen 5 of this embodiment, when performing borderless recording on the recording paper S1, the recording paper S1, which is restricted by the first restricting section 22A and the second restricting section 22B that take the second restricting position, is transported from the paper setting section 8 to the platen 5, and S108 and S109 are performed in the same manner as in the first embodiment, so that ink is easily received in the recesses 5B2 and 5B3 and ink is less likely to adhere to the opposing surface 5A. Therefore, the problem of ink adhering to the opposing surface 5A transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur.

[0093] [Third Embodiment] Next, with reference to Figures 13 to 16, an image recording system according to a third embodiment of the present invention will be described. The image recording system in this embodiment is the same as in the first embodiment, except that the configuration of the first regulating unit 322A and the second regulating unit 322B differs from that of the first regulating unit 22A and the second regulating unit 22B of the first embodiment, and the method for determining the recording positions W1 to W4 in S109 is different. In this embodiment as well, the same reference numerals are used to indicate components similar to those in the first embodiment, and their descriptions are omitted. In this embodiment as well, the first regulating unit 322A and the second regulating unit 322B are provided in the manual feed tray 8B.

[0094] As shown in Figures 13 and 16, the first restricting portion 322A in this embodiment has a restricting portion body 322A1 and a detachable portion 322A2. The restricting portion body 322A1 is a plate-shaped member extending in the front-rear and up-down directions. The detachable portion 322A2 is configured to be detachably attached to the restricting portion body 322A1 and has thickness in the left-right direction. As shown in Figure 16(b), the detachable portion 322A2 has a groove portion 322A3 that opens downward. The groove portion 322A3 extends in the front-rear direction and can be fitted with the restricting portion body 322A1. The detachable portion 322A2 is configured to be attached to the restricting portion body 322A1 from above, making it possible to easily attach the detachable portion 322A2 to the restricting portion body 322A1.

[0095] As shown in Figures 13 and 16, the first regulating section 322A is for regulating and positioning the right edge ER of the recording paper S stored in the paper storage section 21 by contacting the right edge ER of the recording paper S in the left-right direction, with the regulating section body 322A1 or the attachment / detachment section 322A2 being the regulating section body 322A1 or the attachment / detachment section 322A2 being the attachment / detachment section 22A2. Specifically, the regulating section body 322A1 has a body contact surface 322A5 that can contact the right edge ER of the recording paper S. The body contact surface 322A5 is the left side of the regulating section body 322A1. The attachment / detachment section 322A2 also has a contact surface 322A6 that can contact the right edge ER of the recording paper S. The contact surface 322A6 is the left side of the attachment / detachment section 22A2.

[0096] The second restricting section 322B is located to the left of the first restricting section 322A and extends in the front-to-back direction. The second restricting section 322B has a shape that is symmetrical to the main restricting section body 322A1 in the left-to-right direction. The second restricting section 322B contacts the left edge EL of the recording paper S stored in the paper storage section 21 to restrict and position the position of the left edge EL of the recording paper S in the left-to-right direction. In other words, the second restricting section 322B has a contact surface 322B1 that can contact the left edge EL of the recording paper S. The contact surface 322B1 is the right side of the second restricting section 322B.

[0097] Furthermore, the main body 322A1 of the first restricting unit 322A is fixed to the paper storage unit 21. In other words, the main body 322A1 of the restricting unit does not move in the left-right direction. Therefore, the first restricting unit 322A, to which the attachment / detachment unit 322A2 is attached, also does not move in the left-right direction. On the other hand, the second restricting unit 322B is configured to be movable in the left-right direction along a pair of guide grooves 327 that run in the left-right direction. In other words, the second restricting unit 322B can move to the left and right to match the left-right size of the recording paper S stored in the paper storage unit 21.

[0098] In this embodiment, the recording paper S stored in the paper storage section 21 is positioned in the left-right direction based on the main body contact surface 322A5 or contact surface 322A6 of the first regulating section 322A. The main body contact surface 322A5 is the surface that becomes the reference position K1 during positioning. The contact surface 322A6 is the surface that becomes the reference position K2 during positioning. In this embodiment, the reference position K1 corresponds to the "first reference position" of the present invention, and the reference position K2 corresponds to the "second reference position" of the present invention. In this embodiment, the left-right position of the main body contact surface 322A5 is the same position as the main body contact surface 22A5 of the first regulating section 22A that takes the first regulating position when regulating the recording paper S2 in the first embodiment. In other words, as shown in Figure 14, in this embodiment, when the right end ER of the recording paper S2 is restricted by the main body contact surface 322A5 and the left end EL is restricted by the contact surface 322B1 for positioning, the center positions of the left end EL and the right end ER of the recording paper S2 coincide with the aforementioned central axis C1.

[0099] In this embodiment, the first restricting position is the position at which the first restricting section 322A and the second restricting section 322B restrict the position of the recording paper S when the right edge ER of the recording paper S is restricted by the main body contact surface 322A5 and the left edge EL is restricted by the contact surface 322B1. On the other hand, the second restricting position is the position at which the first restricting section 322A and the second restricting section 322B restrict the position of the recording paper S when the right edge ER of the recording paper S is restricted by the contact surface 322A6 and the left edge EL is restricted by the contact surface 322B1.

[0100] When the recording paper S2, which is restricted by the first restricting section 322A and the second restricting section 322B that take the first restricting position, is transported from the paper setting section 8 onto the platen 5, as shown in Figure 15, the distance L2 in the rightward direction between the right edge ER of the recording paper S2 and the rib 16C closest to the right of the right edge ER, and the distance L2 in the leftward direction between the left edge EL of the recording paper S2 and the rib 16D closest to the left of the left edge EL are the same distance L2 as in the first embodiment. When borderless recording is performed with the recording paper S2 transported from the paper setting section 8 onto the platen 5, the upper surfaces of the ribs 16C and 16D are in a position where almost no ink that has spilled over from the recording paper S2 adheres to them. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur. Therefore, in this embodiment as well, the recording paper S2 may be restricted by the first restriction unit 322A and the second restriction unit 322B, which take the first restriction position, regardless of whether bordered or borderless recording is performed.

[0101] As shown in Figure 13, when the recording paper S1 is restricted by the first restriction section 322A and the second restriction section 322B, which take the first restriction position, the center position of the left edge EL and the right edge ER of the recording paper S1 is positioned to the right of the aforementioned central axis C1. When this recording paper S1 is transported from the paper setting section 8 onto the platen 5, as shown in Figure 15, the distance to the right of the right edge ER of the recording paper S1 and the rib 16C closest to the right of the right edge ER is distance L2, but the left edge EL of the recording paper S1 partially overlaps with the rib 16E. In this way, when the recording paper S1 is transported from the paper setting section 8 onto the platen 5 and borderless recording is performed, the ink that has spilled from the recording paper S1 is in a position where it is likely to adhere to the upper surface of the rib 16E. Therefore, the ink that has spilled from the recording paper S1 is likely to transfer to the next feeding of the recording paper S, causing the recording paper S to become dirty.

[0102] As shown in Figure 16, the recording paper S1, restricted by the first restricting section 322A and the second restricting section 322B which take the second restricting position, has its left-right center coincide with axis C2. Therefore, when the recording paper S1 is transported from the paper setting section 8 onto the platen 5, the state shown in Figure 10(b) is achieved, and the distance L3 is the distance to the right between the right edge ER of the recording paper S1 and the rib 16A closest to the right of the right edge ER, and the distance L3 is the distance to the left between the left edge EL of the recording paper S1 and the rib 16D closest to the left of the left edge EL. As a result, even when borderless recording is performed while the recording paper S1 is transported onto the platen 5, almost no ink spills from the recording paper S1 onto the upper surfaces of the ribs 16A and 16D. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur.

[0103] In this embodiment, in S109, the image recording position W1 when performing borderless recording on recording paper S1 is determined based on the reference position K2, and the image recording positions W2 to W4 when performing bordered recording on recording paper S1, when performing bordered recording on recording paper S2, and when performing borderless recording on recording paper S2 are determined based on the reference position K1.

[0104] The control unit 80 predetermines the recording position W1 as the position where the right edge of image G3 extends beyond the reference position K1 by a distance WR. Then, when performing borderless recording on recording paper S1, the control unit 80 redetermines the predetermined recording position W1 by shifting it based on the amount by which the reference position K2 has shifted horizontally relative to the reference position K1. As a result, when performing borderless recording on recording paper S1, ink is ejected from the head 4 onto recording paper S1 at a timing such that the right edge of image G3 aligns with the position where it extends beyond the reference position K2 by a distance WR. On the other hand, when performing borderless recording on recording paper S2, the control unit 80 predetermines the recording position W4 as the position where the right edge of image G3 extends beyond the reference position K1 by a distance WR. As a result, ink is ejected from the head 4 onto recording paper S2 at a timing such that the right edge of image G3 aligns with the position where it extends beyond the reference position K1 by a distance WR. Furthermore, when performing bordered recording on recording paper S1, or when performing bordered recording on recording paper S2, the control unit 80 determines the recording positions W2 and W3 so that the right edge of image G1 leaves a margin M to the left of the reference position K1. As a result, ink is ejected from the head 4 onto recording paper S1 and S2 at a timing such that the right edge of image G1 leaves a margin M to the left of the reference position K1.

[0105] In this embodiment, when recording with a border on the recording paper S1, the detachable part 322A2 is removed from the regulating part body 322A1, and the recording paper S1 is regulated by the first regulating part 322A and the second regulating part 322B which take the first regulating position, thereby recording with a border on the recording paper S1, similar to the first embodiment. Furthermore, when recording without a border on the recording paper S1, the detachable part 322A2 is attached to the regulating part body 322A1, and the recording paper S1 is regulated by the first regulating part 322A and the second regulating part 322B which take the second regulating position, thereby reducing the amount of ink that spills over from the right edge ER and left edge EL of the recording paper S1 and adheres to the upper surface of the rib 16, similar to the first embodiment.

[0106] The first restricting unit 322A and the second restricting unit 322B are configured such that only the second restricting unit 322B is movable in the left-right direction, and when the recording paper S is held in the left-right direction, the right edge of the recording paper S can be selectively positioned at either the reference position K1 or the reference position K2. Even if the second restricting unit 322B is configured to be movable in the left-right direction, if the right edge of the recording paper S can only be positioned at either the reference position K1 or the reference position K2, then to position it at the other reference position, it would be necessary to position the recording paper S without using the first restricting unit 322A, making it extremely difficult to accurately transport the recording paper S along arrow A. However, in this configuration, when the recording paper S is held in the left-right direction, the right edge of the recording paper S can be selectively positioned at either the reference position K1 or the reference position K2, thus improving the accuracy of the left-right transport position of the recording paper S.

[0107] [Fourth Embodiment] Next, with reference to Figures 17 to 19, an image recording system according to the fourth embodiment of the present invention will be described. The image recording system in this embodiment is the same as the third embodiment except that the configuration of the first regulating unit 422A differs from that of the first regulating unit 322A in the third embodiment, and a sensor 461 is provided instead of the mounting sensor 22A4 in the first embodiment. In configurations similar to the third embodiment, the same reference numerals are used and the description is omitted. The sensor 461 in this embodiment corresponds to the "detection unit" of the present invention. In this embodiment as well, the first regulating unit 422A and the sensor 461 are provided in the manual feed tray 8B.

[0108] As shown in Figures 17 and 18, the first restricting section 422A in this embodiment has a third restricting section 431 and a fourth restricting section 441, and is intended to contact the right edge ER of the recording paper S stored in the paper storage section 21, thereby restricting and positioning the position of the right edge ER of the recording paper S in the left-right direction. In other words, the third restricting section 431 has a contact surface 431A that can contact the right edge ER of the recording paper S. The contact surface 431A is the left side of the third restricting section 431. The fourth restricting section 441 also has a contact surface 441A that can contact the right edge ER of the recording paper S. The contact surface 441A is the left side of the fourth restricting section 441.

[0109] As shown in Figure 17, the third restricting section 431 is a plate-shaped member extending in the front-rear and up-down directions. The bottom surface of the paper storage section 21 has a recess 451 that opens upward. The recess 451 has a planar size that can accommodate the third restricting section 431. The third restricting section 431 is configured to be rotatable relative to the paper storage section 21 about a rotation axis 431B at its lower end. The rotation axis 431B is parallel to the front-rear direction.

[0110] The third restricting section 431 is configured to be able to take two positions: a restricting state in which it is erected vertically, as shown in Figure 17(b), and a retracted state in which it is housed in the recess 451, as shown in Figure 18(b). When the third restricting section 431 is in the restricting state, it is in a position where the contact surface 431A can restrict the right edge ER of the recording paper S. On the other hand, when the third restricting section is in the retracted state, it is housed in the recess 451 and is in a position where it cannot restrict the recording paper S.

[0111] As shown in Figure 18, the fourth restricting section 441 is a plate-shaped member extending in the front-rear and up-down directions. The fourth restricting section 441 is positioned further to the right of the second restricting section 322B and the third restricting section 431. The third restricting section 431 and the fourth restricting section 441 are fixed to the paper storage section 21 and do not move in the left-right direction. Furthermore, the fourth restricting section 441 has the same configuration as the restricting section body 322A1 of the third embodiment described above.

[0112] In this embodiment, the recording paper S stored in the paper storage section 21 is positioned in the left-right direction based on the contact surface 431A or contact surface 441A of the first regulating section 422A. The contact surface 441A is the surface that becomes the reference position K1 during positioning. The contact surface 431A is the surface that becomes the reference position K2 during positioning. In this embodiment, the reference position K1 corresponds to the "first reference position" of the present invention, and the reference position K2 corresponds to the "second reference position" of the present invention. In this embodiment, the left-right position of the contact surface 441A is the same position as the main body contact surface 322A5 in the third embodiment described above. The left-right position of the contact surface 431A is the same position as 322A6 in the third embodiment described above.

[0113] In this embodiment, the first restricting position is the position at which the first restricting section 422A and the second restricting section 322B restrict the position of the recording paper S when the right edge ER of the recording paper S is restricted by the contact surface 441A and the left edge EL is restricted by the contact surface 322B1. On the other hand, the second restricting position is the position at which the first restricting section 422A and the second restricting section 322B restrict the position of the recording paper S when the right edge ER of the recording paper S is restricted by the contact surface 431A and the left edge EL is restricted by the contact surface 322B1.

[0114] In this embodiment as well, similar to the third embodiment, when borderless recording is performed on the recording paper S2, which is restricted by the first restricting unit 422A and the second restricting unit 322B that take the first restricting position, after it has been transported from the paper setting unit 8 onto the platen 5, the upper surfaces of the ribs 16C and 16D are in a position where almost no ink that has spilled from the recording paper S2 adheres to them. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur. Accordingly, in this embodiment as well, the recording paper S2 may be restricted by the first restricting unit 422A and the second restricting unit 322B that take the first restricting position, regardless of whether bordered recording or borderless recording is performed.

[0115] As shown in Figure 18, the recording paper S1 restricted by the first restricting section 422A and the second restricting section 322B, which take the first restricting position, has the center of the left edge EL and the right edge ER of the recording paper S1 positioned to the right of the aforementioned central axis C1. The recording paper S1 restricted by the first restricting section 422A and the second restricting section 322B, which take the first restricting position, is in a position where ink that has spilled from the recording paper S1 is likely to adhere to the upper surface of the rib 16E when borderless recording is performed while it is being transported from the paper setting section 8 onto the platen 5, similar to the third embodiment. As a result, the ink that has spilled from the rib 16E is likely to transfer to the next feeding of recording paper S, causing the recording paper S to become dirty.

[0116] As shown in Figure 17, the recording paper S1, restricted by the first restricting section 422A and the second restricting section 322B which take the second restricting position, has its left-right center coincide with axis C2. Therefore, when the recording paper S1 is transported from the paper setting section 8 onto the platen 5, it is in the state shown in Figure 10(b). Consequently, even if borderless recording is performed while the recording paper S1 is transported from the paper setting section 8 onto the platen 5, almost no ink that has spilled from the recording paper S1 adheres to the upper surfaces of the ribs 16A and 16D. Therefore, the problem of ink adhering to the upper surface of the ribs 16 transferring to the next feeding of recording paper S and soiling the recording paper S is less likely to occur.

[0117] Sensor 461 is located within recess 451. Sensor 461 detects whether the recording paper S is restricted by the third restriction unit 431 or the fourth restriction unit 441. Sensor 461 is a known mechanical switch and contacts the third restriction unit 431 when the third restriction unit 431 is in a containment state. At this time, sensor 461 outputs a signal to the control unit 80 indicating that the fourth restriction unit 441 is restricting the recording paper S and that sensor 461 is in contact with the third restriction unit 431. On the other hand, sensor 461 does not contact the third restriction unit 431 when the third restriction unit 431 is in a restricting state. At this time, sensor 461 outputs a signal to the control unit 80 indicating that the third restriction unit 431 is restricting the recording paper S and that sensor 461 is not in contact with the third restriction unit 431. As a modified example, a sensor for detecting the position of the recording paper S regulated by the third regulating unit 431 and the second regulating unit 322B may be provided in place of sensor 461, and based on the position of the recording paper S detected by the sensor, it may be detected whether the third regulating unit 431 or the fourth regulating unit 441 is regulating the recording paper S.

[0118] In this embodiment as well, when image recording is performed on the recording paper S1, as shown in Figure 19, after S101 and S102 described above, the control unit 80 determines whether or not the third regulating unit 431 will regulate the recording paper S1 based on the signal from the sensor 461 (S201).

[0119] If the control unit 80 determines in S201 that the fourth regulating unit 441 is regulating the recording paper S1 (S201: NO), it outputs a control signal to the control unit 103 to display a message on the display unit 102 indicating that "the third regulating unit 431 is not regulating the recording paper S1". The control unit 103 then controls the display unit 102 based on the control signal to display the message (S202). This allows the user to be informed that the recording paper S1 is not being regulated by the third regulating unit 431 and to be prompted to have the third regulating unit 431 regulate it.

[0120] After S202, the process returns to S201 and the processing of S201 is executed. When the user sets the third restricting unit 431 upright to enter the restricting state, the sensor 461 outputs a signal indicating that the third restricting unit 431 restricts the recording paper S. At this time, the position of the recording paper S1 is restricted by the third restricting unit 431 and the second restricting unit 322B of the first restricting unit 422A, which takes the second restricting position. If the control unit 80 determines in S201 that the third restricting unit 431 restricts the recording paper S1 (S201: YES), it executes the paper feeding process of S105 described above. Thereafter, the same flow as in the first embodiment described above is executed, and borderless recording is performed on the recording paper S1.

[0121] In this embodiment as well, when performing borderless recording on the recording paper S1, the third restricting section 431 is set to a restricting state, and the recording paper S1 is restricted by the third restricting section 431 and the second restricting section 322B of the first restricting section 422A, which takes the second restricting position. This reduces the amount of ink that spills over from the right edge ER and left edge EL of the recording paper S1 onto the upper surface of the rib 16, similar to the first embodiment. Furthermore, when performing bordered recording on the recording paper S1, the third restricting section 431 is set to a stowed state, and the recording paper S1 is restricted by the fourth restricting section 441 and the second restricting section 322B of the first restricting section 422A, which takes the first restricting position. This allows for bordered recording on the recording paper S1, similar to the first embodiment.

[0122] In this way, by simply changing the regulating unit that regulates the recording paper S1 with the second regulating unit 322B to either the third regulating unit 431 or the fourth regulating unit 441, the first regulating unit 422A and the second regulating unit 422B can selectively take the first regulating position and the second regulating position as their regulating positions. In other words, the right edge ER of the recording paper S can be selectively placed at either the reference position K1 or K2, and an image can be recorded on the recording paper S based on the reference positions K1 or K2. The same effect can be obtained with configurations similar to those of the embodiments described above.

[0123] The third regulating unit 431 is configured to selectively select between a position where the recording paper S1 is regulated at the second regulating position and a position where it cannot be regulated. This makes it possible to easily change the regulating position that restricts the position of the recording paper S1.

[0124] The fourth regulating section 441 is fixed to the paper storage section 21. This simplifies the configuration of the first regulating section 422A.

[0125] A sensor 461 is provided. This allows it to determine whether the regulating position for the recording paper S1 is the first regulating position or the second regulating position.

[0126] [Fifth Embodiment] Next, with reference to Figures 20 and 21, an image recording system according to the fifth embodiment of the present invention will be described. The image recording system in this embodiment is the same as in the first embodiment, except that the configuration of the first regulating unit 522A and the configuration of the interlocking mechanism 520 that interlocks the first regulating unit 522A and the second regulating unit 22B are different from the configuration of the first embodiment. In this embodiment as well, the same reference numerals are used to indicate the same components as in the first embodiment, and their descriptions are omitted. In this embodiment as well, the first regulating unit 522A and the interlocking mechanism 520 are provided in the manual feed tray 8B.

[0127] The first regulating section 522A has the same configuration as the regulating section body 22A1 of the first embodiment and has a contact surface 522A1 that can contact the right edge ER of the recording paper S. The interlocking mechanism 520 has two gear units 520A and 520B instead of the pinion gear 28 described above.

[0128] As shown in Figure 20(b), the gear unit 520A has three pinion gears 520A1 to 520A3. These pinion gears 520A1 to 520A3 are arranged in a line in the front-to-back direction, with two pinion gears 520A1 and 520A2, and two pinion gears 520A2 and 520A3 meshing with each other. The three pinion gears 520A1 to 520A3 are all the same size and consist of pinion gears with the same number of teeth.

[0129] The gear unit 520B has three pinion gears 520B1 to 520B3. These pinion gears 520B1 to 520B3 are also arranged in a line in the front-to-back direction, with two pinion gears 520B1 and 520B2, and two pinion gears 520B2 and 520B3 meshing with each other. The three pinion gears 520B1 to 520B3 are of different sizes and consist of pinion gears with different numbers of teeth.

[0130] The interlocking mechanism 520 is configured to selectively take between two states: a first state in which only one of the two gear units 520A and gear unit 520B, gear unit 520A, engages with the two rack gears 26A and 26B, and a second state in which only the other gear unit 520B engages with the two rack gears 26A and 26B. In other words, the interlocking mechanism 520 takes the first state by positioning the lever of a switching mechanism (not shown) to the first position. In this state, pinion gear 520A1 engages with rack gear 26A, and pinion gear 520A3 engages with rack gear 26B. On the other hand, the interlocking mechanism 520 takes the second state by positioning the lever to a second position different from the first position. In this state, pinion gear 520B1 engages with rack gear 26A, and pinion gear 520B3 engages with rack gear 26B.

[0131] The two gear units 520A and 520B have different gear ratios when transmitting the movement of the first restricting unit 522A to the second restricting unit 22B. As shown in Figure 20(a), when the gear unit 520A is positioned with the first restricting unit 522A and the second restricting unit 22B at their furthest outer positions in the left-right direction, the first restricting unit 522A is moved to the left by a distance L7 to restrict the right edge ER of the recording paper S1, and the second restricting unit 22B is moved to the right by a distance L8 to restrict the left edge EL. Distances L7 and L8 are the same. In this way, the gear unit 520A has the same function as the pinion gear 28 of the first embodiment.

[0132] As shown in Figure 20(a), when the gear unit 520B is positioned with the first restricting section 522A and the second restricting section 22B at their furthest outward positions in the left-right direction, moving the first restricting section 522A to the left by a distance L7 to restrict the right edge ER of the recording paper S1 will move the second restricting section 22B to the right by a distance L9. Distance L9 is shorter than distance L8. Thus, the gear ratio of the gear unit 520B is such that the second restricting section 22B moves by a distance smaller than the distance the first restricting section 522A is moved.

[0133] With this configuration, when the interlocking mechanism 520 is in the first state, when the first restricting unit 522A moves a distance L7, the second restricting unit 22B moves a distance L8. On the other hand, when the interlocking mechanism 520 is in the second state, when the first restricting unit 522A moves a distance L7, the second restricting unit 22B moves a distance L9.

[0134] When the interlocking mechanism 520 takes the first state, if the right end ER of the recording paper S1 is restricted by the first restricting unit 522A and the left end EL is restricted by the second restricting unit 22B, the left-right center of the recording paper S1 coincides with the central axis C1. At this time, the first restricting unit 522A and the second restricting unit 22B take the first restricting position.

[0135] On the other hand, when the interlocking mechanism 520 takes the second state, as shown in Figure 21, the first restricting unit 522A and the second restricting unit 22B are positioned at their furthest outer positions in the left-right direction. When the first restricting unit 522A is moved to the left by a distance L10 to restrict the right edge ER of the recording paper S1, the second restricting unit 22B is moved to the right by a distance L11, which is shorter than L10, to restrict the left edge EL. At this time, the left-right center of the recording paper S1 coincides with axis C2. At this time, the first restricting unit 522A and the second restricting unit 22B take the second restricting position.

[0136] In this embodiment, when performing bordered recording on the recording paper S1, the interlocking mechanism 520 is made to take a first state, and the recording paper S1 is restricted by the first restricting section 522A and the second restricting section 22B which take a first restricting position, thereby performing bordered recording on the recording paper S1, similar to the first embodiment. Furthermore, when performing borderless recording on the recording paper S1, the interlocking mechanism 520 is made to take a second state, and the recording paper S1 is restricted by the first restricting section 522A and the second restricting section 22B which take a second restricting position, thereby reducing the adhesion of ink that has spilled over from the right edge ER and left edge EL of the recording paper S1 to the upper surface of the rib 16, similar to the first embodiment.

[0137] The interlocking mechanism 520 is configured to be switchable between a first state and a second state, making it possible to switch the restricted position between the first restricted position and the second restricted position. Furthermore, with a simple configuration of the interlocking mechanism 520 in which the gear ratios of the two gear units 520A and 520B are different, it is possible to selectively position the recording paper S1 between the first restricted position and the second restricted position.

[0138] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications are possible as long as they are within the scope of the claims.

[0139] Furthermore, the media sensor 89 can also detect the positions of the right edge ER and left edge EL of the recording paper S when it reaches a position on the platen 5 opposite the media sensor 89. As shown in Figure 22, after S108 and before the recording process of S109 is performed, the control unit 80 determines, based on the detection signal from the media sensor 89, whether the recording paper S1 was restricted to a predetermined position by the first and second restricting units located at the second restricting position (S301). In other words, the control unit 80 derives the left-right edge positions of the recording paper S1 based on the timing of acquiring the detection signal from the media sensor 89. Then, based on the edge positions of the recording paper S1, it determines whether the recording paper S1 was restricted to a predetermined position. The predetermined position here refers to either the position where the center of the recording paper S1 is located on axis C2, which is the second reference position, or the position where the right edge ER of the recording paper S1 is located on reference position K2.

[0140] If the control unit 80 determines in S301 that the recording paper S1 is not restricted to a predetermined position (S301: NO), it outputs a control signal to the control unit 103 to display information on the display unit 102 indicating that the recording paper S1 is not restricted to a predetermined position. The control unit 103 then controls the display unit 102 based on the control signal to display the information (S302). After S302, the process returns to S301, and the process in S301 is executed. If the control unit 80 determines in S301 that the recording paper S1 is restricted to a predetermined position (S301: YES), it executes the recording process in S109.

[0141] In this way, the control unit 80 acquires a detection signal from the media sensor 89 when performing borderless recording, and can use it to confirm the position of the recording paper S1 without providing a separate sensor from the media sensor 89. The media sensor 89 may be attached to the carriage 2 to perform control according to the position of the left and right edges of the recording paper S, and by using this media sensor 89, the overall configuration of the device can be simplified.

[0142] Furthermore, the paper setting unit 8 in each of the above embodiments may have only either the paper feed tray 8A or the manual feed tray 8B. Also, the first regulating unit and the second regulating unit may be provided only in either the paper feed tray 8A or the manual feed tray 8B.

[0143] In the first and second embodiments, the first restricting unit 22A and the second restricting unit 22B may be configured to be individually movable to any position in the left-right direction. Alternatively, the first restricting unit 22A and the second restricting unit 22B may be configured to be detachable and to be positioned at any position in the left-right direction. In these cases as well, it is sufficient that the first restricting unit 22A and the second restricting unit 22B are configured to selectively take between the first restricting position and the second restricting position. In this case, in the recording process of S109, if bordered recording is to be performed, the image should be recorded on the recording paper S based on the central axis C1, and if borderless recording is to be performed, the image should be recorded on the recording paper S1 based on axis C2. This makes it possible to obtain the same effects as in the first and second embodiments.

[0144] The third restricting portion 431 in the fourth embodiment may be configured to be detachable. In this case, when the third restricting portion 431 is attached, it can take on a second restricting position together with the second restricting portion 322B, and when the third restricting portion 431 is removed, the fourth restricting portion 441 and the second restricting portion 322B can take on a first restricting position. In this case as well, the same effects as in the fourth embodiment can be obtained. Furthermore, the fourth restricting portion 441 may be configured to be movable in the left-right direction, or it may be configured to be detachable.

[0145] The attached sensors 22A4 and 461 do not necessarily have to be provided. In this case, in S103, the user may determine whether the recording paper S1 is in the second reference position. Specifically, the user can select YES or NO in response to the question "Is the recording paper S1 in the second reference position?" displayed on the display unit 102. Alternatively, the above message or other information may be displayed on a display unit (not shown) of the printer 1 instead of the display unit 102. Furthermore, the control units 80 and 103 do not need to perform control to display the message or other information on the display unit 102.

[0146] In the second embodiment described above, there may be no three forms 5C, or there may be one or two forms 5C. Also, through holes may be used instead of recesses 5B1 to 5B3.

[0147] The notification unit may be the display unit or speaker of the printer 1. In this case, notifications to the user may be made not only by images including messages displayed on the display unit, but also by sound from the speaker, controlled by the control unit 80. Furthermore, as an error handling measure, the transport of the recording paper S may be stopped.

[0148] In each of the embodiments described above, when performing borderless recording on the recording paper S1, the control unit 80 records an image on the recording paper S1 based on the axis C2 or the reference position K2. At this time, the adhesion of excess ink from both the right edge ER and the left edge EL of the recording paper S1 to the upper surface of the rib 16 or the opposing surface 5A supporting the recording paper S1 was reduced, but the adhesion of excess ink from either the right edge ER or the left edge EL may also be reduced.

[0149] In the embodiments described above, examples were given in which the present invention is applied to an inkjet printer equipped with a so-called serial head that ejects ink from multiple nozzles while moving left and right with the carriage, but the invention is not limited to this. For example, the present invention can also be applied to an inkjet printer equipped with a so-called line head that extends along the entire length of the platen 5 in both left and right directions. Furthermore, the present invention can also be applied to a laser printer that records images by adhering toner to recording paper. In this case, the toner corresponds to the "colorant" of the present invention. [Explanation of symbols]
