Abstract
Description
[[TECHNICAL FIELD]]
[0001] The present invention relates to an image recording apparatus that records an image. [[BACKGROUND ART]]
[0002] As an example of an image recording apparatus that records an image, Patent Document 1 describes a combined recording and cutting apparatus that records an image on a medium and cuts the medium on which the image has been recorded. In the combined recording and cutting apparatus described in Patent Document 1, a cutting section is disposed below a recording section. The medium on which an image has been recorded by the recording section is conveyed by a reversing guide roller to a medium support belt of the cutting section such that the recording surface of the medium on which the image is recorded faces downward. The cutting section includes a cutting section carriage, a cutter head, and a cutter. The cutting section carriage is movable in a horizontal direction orthogonal to the conveyance direction of the medium. The cutter head is mounted on the carriage so as to be capable of moving up and down and rotating about a vertical axis. The cutter is held by the cutter head. Then, with the lower end of the cutter penetrating the medium, the cutting section carriage is moved, and the medium support belt is driven to move the medium, thereby cutting the medium.

[0003] [[Patent Document 1]] Japanese Unexamined Patent Application Publication No. 2007-55038 [[SUMMARY OF THE INVENTION]] [[Problem to be Solved by the Invention]]
[0004] In this case, the recording and cutting combined device described in Patent Document 1 is configured such that the leading edge of the medium being recorded is gripped by the medium support belt. It is also considered that the trailing edge of the medium being cut is gripped by the medium support belt. In such a configuration, it is difficult to have the medium support belt perform both the transport operation corresponding to recording and the transport operation corresponding to cutting simultaneously. In other words, when one medium is being cut, another medium with an image recorded on it cannot be kept waiting near the cutting section. If another medium with an image recorded on it cannot be kept waiting when one medium is being cut, the efficiency of image recording and medium cutting becomes poor when recording and cutting images on multiple media consecutively.
[0005] The object of the present invention is to provide an image recording device capable of efficiently recording and cutting images on a recording medium. [Means for solving the problem]
[0006] The image recording apparatus of the present invention comprises a recording unit for recording an image on a recording medium, a cutting unit for cutting the recording medium on which the image has been recorded in the recording unit into a free shape, and a transport unit having a transport path for transporting the recording medium on which the image has been recorded in the recording unit to the cutting unit, and transporting the recording medium along the transport path. The transport path has a waiting position for a second recording medium, which has an image recorded in the recording unit and is separate from the first recording medium, to wait while the first recording medium on which the image has been recorded is being cut in the cutting unit. [Effects of the Invention]
[0007] According to the present invention, while the first recording medium is being cut in the cutting section, the second recording medium on which an image has been recorded in the recording section can be kept waiting at a waiting position on the transport path. Therefore, after the cutting of the first recording medium is completed in the cutting section, the second recording medium that was waiting at the waiting position can be transported to the cutting section. As a result, the recording of images on multiple recording media and the cutting of recording media on which images have been recorded can be performed efficiently. [Brief explanation of the drawing]

[0009] Preferred embodiments of the present invention will be described below.
[0010] <Overall Configuration of Printer> As shown in FIGS. 1 and 2, the printer 1 of the present embodiment includes a housing 1A, a recording section 2, a paper discharge tray 3, a manual feed tray 4, a paper cassette 5, a cutting section 6, and a conveyance section 7. In the present embodiment, the printer 1 corresponds to the "image recording apparatus" of the present invention.
[0011] Hereinafter, as shown in FIGS. 1 and 2, description will be given with definitions of upward direction, downward direction, forward direction, rearward direction, left direction, and right direction. The downward direction is opposite to the upward direction. The rearward direction is opposite to the forward direction. The right direction is opposite to the left direction. In addition, a generic term for directions parallel to the upward direction and the downward direction is the vertical direction. A generic term for directions parallel to the forward direction and the rearward direction is the front-rear direction. A generic term for directions parallel to the left direction and the right direction is the left-right direction. The vertical direction is orthogonal to the front-rear direction and the left-right direction. The front-rear direction is orthogonal to the left-right direction.
[0012] The housing 1A is formed in a substantially rectangular parallelepiped shape. In the housing 1A, a front surface 1A1 that is an end face in the forward direction and a rear surface 1A2 that is an end face in the rearward direction face each other in the front-rear direction. The recording section 2, the paper discharge tray 3, the manual feed tray 4, the paper cassette 5, the cutting section 6, and the like are provided in the housing 1A.
[0013] The recording unit 2 is the part for recording images onto the recording paper S. In this embodiment, the recording paper S is a sheet of paper or a single sheet cut to a predetermined size. In this embodiment, the recording paper S corresponds to the "recording medium" of the present invention.
[0014] As shown in Figure 2, the recording unit 2 is located at the top of the housing 1A. The recording unit 2 is also located between the front 1A1 and the rear 1A2 in the front-to-back direction. As shown in Figures 2 and 3, the recording unit 2 includes a head carriage 11, a sub-tank 12, a head 13, a platen 14, and transport rollers 15 and 16.
[0015] The head carriage 11 mounts the sub-tank 12 and the head 13. The head carriage 11 is supported by two guide rails 19A and 19B that extend in the left-right direction, allowing it to move to the left and to the right. The head carriage 11 is connected to the head carriage motor 106 shown in Figure 6 via a belt or the like (not shown). The head carriage 11 moves to the left and to the right along the guide rails 19A and 19B as the head carriage motor 106 is driven.
[0016] Here, printer 1 is equipped with four cartridge mounting sections 21. The four cartridge mounting sections 21 are located at the front of the upper part of the housing 1A and are positioned to the right of the paper output tray 3. The four cartridge mounting sections 21 are arranged side by side in the left-right direction.
[0017] Each cartridge mounting section 21 has an opening at the front, through which the ink cartridge 22 can be inserted and removed. In other words, the printer 1 can insert ink cartridges 22 through the openings on the front 1A1 of the housing 1A and the openings on the cartridge mounting sections 21. The ink cartridge 22 that stores black ink is removablely installed in the leftmost cartridge mounting section 21. The ink cartridge 22 that stores yellow ink is removablely installed in the second cartridge mounting section 21 from the left. The ink cartridge 22 that stores cyan ink is removablely installed in the second cartridge mounting section 21 from the right. The ink cartridge 22 that stores magenta ink is removablely installed in the rightmost cartridge mounting section 21.
[0018] Although a detailed explanation is omitted, one or more covers may be provided over the opening on the front surface 1A1 of the housing 1A and the opening of the cartridge mounting section 21. In this embodiment, the ink corresponds to the "recording material" of the present invention.
[0019] The ink cartridges 22 installed in each cartridge mounting section 21 are connected to the sub-tank 12 via tubes 23. The ink in the ink cartridges 22 is supplied to the sub-tank 12 via tubes 23.
[0020] The print head 13 is connected to the bottom surface of the sub-tank 12. The print head 13 has a nozzle surface 13A with a plurality of nozzles 10 on its lower side. The print head 13 ejects ink supplied from the sub-tank 12 from the plurality of nozzles 10. More specifically, the plurality of nozzles 10 are arranged in the front-to-back direction to form a nozzle row 9. Four rows of nozzle rows 9 are arranged side-by-side on the nozzle surface 13A. The print head 13 ejects black ink from the plurality of nozzles 10 that form the rightmost nozzle row 9. The print head 13 ejects yellow ink from the plurality of nozzles 10 that form the second nozzle row 9 from the right. The print head 13 ejects cyan ink from the plurality of nozzles 10 that form the second nozzle row 9 from the left. The print head 13 ejects magenta ink from the plurality of nozzles 10 that form the leftmost nozzle row 9.
[0021] The platen 14 is located below the head 13. The platen 14 supports the recording paper S from below.
[0022] The transport rollers 15 and 16 are rollers whose axial direction is in the left-right direction. Transport roller 15 is positioned behind the head 13 and platen 14. Transport roller 16 is positioned in front of the head 13 and platen 14. The transport rollers 15 and 16 are driven and rotated by the roller drive device 107 shown in Figure 6, and transport the recording paper S forward.
[0023] The output tray 3 is the part that ejects the recording paper S on which an image has been recorded by the recording unit 2 when the recording paper S on which an image has been recorded by the recording unit 2 is not cut by the cutting unit 6. The output tray 3 is located at the top of the housing 1A and is positioned in front of the recording unit 2 and the transport rollers 16.
[0024] The manual feed tray 4 is a tray on which recording paper S is supplied to the recording unit 2. The manual feed tray 4 is a so-called MPF or multi-purpose tray. The manual feed tray 4 can hold one sheet of recording paper S or multiple sheets stacked vertically. The manual feed tray 4 is located at the top of the housing 1A, behind the recording unit 2 and the transport rollers 15. The manual feed tray 4 is also located above the paper cassette 5 and behind the paper cassette 5. The manual feed tray 4 is connected to the housing 1A at its front. The surface on which the recording paper S is placed on the manual feed tray 4 extends downwards towards the front. In other words, the surface on which the manual feed tray 4 is placed is inclined with respect to the horizontal plane so that it slopes downwards towards the front. The recording paper S placed on the manual feed tray 4 is supplied into the housing 1A from the front of the manual feed tray.
[0025] The printer 1 also includes a tray feed path 51 and a tray feed roller 61 for supplying recording paper S from the manual feed tray 4 to the recording unit 2. The tray feed path 51 extends from the paper feed opening at the front of the manual feed tray 4 to a position below the head 13. The tray feed roller 61 is a roller whose axis is oriented in the left-right direction. The tray feed roller 61 is located above the mounting surface on the manual feed tray 4 where the recording paper S is placed. The tray feed roller 61 is driven and rotated by the roller drive device 107 shown in Figure 6, and transports the recording paper S. The recording paper S placed on the manual feed tray 4 is transported to the tray feed path 51 by the tray feed roller 61, and then transported to the recording unit 2 by the transport roller 15. When multiple sheets of recording paper S are stacked on the manual feed tray 4, the uppermost sheet of recording paper S is transported by the tray feed roller 61.
[0026] The paper cassette 5 is a tray on which recording paper S supplied to the recording unit 2 is placed. The paper cassette 5 is located in the center of the housing 1A in the vertical direction. The paper cassette 5 is removably mounted in the cassette mounting section 1B. Specifically, the paper cassette 5 can be inserted into and removed from the cassette mounting section 1B from the front. The cassette mounting section 1B is located below the transport rollers 15, 16 and the manual feed tray 4. One sheet of recording paper S, or multiple sheets stacked vertically, are placed in the paper cassette 5.
[0027] The printer 1 also includes a cassette paper feed path 52, a pickup roller 62, and a cassette paper feed roller 63 for supplying recording paper S from the paper cassette 5 to the recording unit 2. The cassette paper feed path 52 extends upward from a position behind the paper cassette 5, merges with the tray paper feed path 51 at the merging section 51A, and extends to a position below the head 13 of the recording unit 2.
[0028] The pickup roller 62 is a roller whose axis is oriented in the left-right direction. The pickup roller 62 is located above the mounting surface of the paper cassette 5 on which the recording paper S is placed. The pickup roller 62 is driven and rotated by the roller drive device 107 shown in Figure 6, and transports the recording paper S. The recording paper S placed in the paper cassette 5 is transported to the cassette paper feed path 52 by the pickup roller 62. When multiple sheets of recording paper S are stacked vertically in the paper cassette 5, the uppermost sheet of recording paper S is transported to the cassette paper feed path 52 by the pickup roller 62.
[0029] The cassette paper feed roller 63 is a roller whose axis is oriented in the left-right direction. The cassette paper feed roller 63 is provided in the cassette paper feed path 52. The cassette paper feed roller 63 is driven and rotated by the roller drive device 107 shown in Figure 6, and transports the recording paper S. The recording paper S is transported to the cassette paper feed path 52 by the pickup roller 62, and then transported to the recording unit 2 by the cassette paper feed roller 63.
[0030] As described above, the recording paper S is supplied to the recording unit 2 from the manual feed tray 4 and the paper cassette 5. However, the printer 1 may be equipped with only one of the manual feed tray 4 and the paper cassette 5. In other words, the printer 1 may be supplied with the recording paper S to the recording unit 2 from only one of the manual feed tray 4 and the paper cassette 5.
[0031] <Cut section> The cutting section 6 is a part for cutting the recording paper S on which the image is recorded into any shape. The free shape can be any shape other than a straight line, such as a circle, square, or star shape. The cutting section 6 is also capable of cutting the paper into a predetermined shape along the contour of the recorded image. The cutting section 6 can also cut the recording paper S in a straight line. The cutting section 6 is located at the bottom of the housing 1A, between the front 1A1 and the rear 1A2 of the housing 1A. The cutting section 6 is also positioned below the recording section 2, the output tray 3, the manual feed tray 4, and the paper cassette 5. As shown in Figures 1 and 4, the cutting section 6 includes a cutter cartridge 31, a cutter carriage 32, a sensor 33, and a cutting section roller 34.
[0032] As shown in Figures 4 and 5(a) to (c), the cutter cartridge 31 comprises a housing 41, a cutter 42, and a holder 43. The housing 41 is cylindrical in shape.
[0033] The cutter 42 has a base 42A and a cutter blade 42B. The base 42A is cylindrical in shape. The base 42A is attached to the lower end of the housing 41 via a bearing 44. The bearing 44 has its axis oriented in the vertical direction. The cutter 42 is rotatably supported on the housing 41 around the axis of the cylindrical base 42A, which is parallel to the vertical direction. The cutter blade 42B is connected to the lower end of the base 42A. The cutter blade 42B is thin and plate-like in shape. The lower end of the cutter blade 42B is inclined with respect to the horizontal direction.
[0034] The holder 43 is cylindrical in shape. The holder 43 is held at the lower end of the housing 41 so as to be movable upward and downward. The entire or a part of the cutter blade 42B is located inside the cylindrical holder 43. A spring 45 is also positioned between the housing 41 and the upper end of the holder 43. The holder 43 is biased downward by the spring 45.
[0035] The cutter carriage 32 is supported by two guide rails 39A and 39B that extend in the left-right direction, allowing it to move in the left and right directions. The cutter carriage 32 is connected to a cutter carriage motor 108 shown in Figure 6. As the cutter carriage motor 108 is driven, the cutter carriage 32 moves along the guide rails 39A and 39B in the left and right directions.
[0036] Furthermore, the cutter carriage 32 is provided with a cutter mounting section 46. The cutter cartridge 31 is mounted on the cutter mounting section 46 by fixing the housing 41 to the cutter mounting section 46.
[0037] Furthermore, the cutter mounting section 46 is connected to a lifting device 47 shown in Figure 6. The lifting device 47 moves the cutter mounting section 46 upward and downward. The cutter cartridge 31 moves upward and downward in conjunction with the upward and downward movement of the cutter mounting section 46.
[0038] Sensor 33 is mounted on the cutter carriage 32. Sensor 33 is used to detect mark M, which will be described later.
[0039] The cutting roller 34 is a roller whose axis is oriented in the left-right direction and is located behind the cutter cartridge 31 and cutter carriage 32. The cutting roller 34 is driven and rotated by the roller drive device 107 shown in Figure 6, and transports the recording paper S in the forward and backward directions. A paper sensor 73 is also located behind the cutting roller 34. The paper sensor 73 is for detecting when the recording paper S reaches the cutting section 6.
[0040] Furthermore, a support member 35 is positioned at the bottom of the housing 1A. The support member 35 is a roughly rectangular plate-shaped member. The support member 35 is located below the cutting section 6. The support member 35 extends from a position that overlaps with the cutting section 6 when viewed from above, to a position behind the position that overlaps with the cutting section 6 when viewed from above. The support member 35 supports the recording paper S from below when the recording paper S is cut at the cutting section 6.
[0041] When cutting the recording paper S in the cutting section 6, the lifting device 47 lowers the cutter mounting section 46, thereby lowering the cutter cartridge 31. More specifically, the cutter cartridge 31 is lowered until the cutter blade 42B of the cutter 42 penetrates the recording paper S, depending on the thickness of the recording paper S to be cut.
[0042] Before the cutter cartridge 31 is lowered, the entire cutter blade 42B is located inside the holder 43, as shown in Figure 5(b). When the cutter cartridge 31 is lowered, the lower end of the holder 43 comes into contact with the recording paper S. This applies an upward force to the holder 43, causing it to move upward against the biasing force of the spring 45. As a result, as shown in Figure 5(c), the tip of the cutter blade 42B is exposed from the holder 43 and penetrates the recording paper S.
[0043] Then, with the tip of the cutter blade 42B penetrating the recording paper S, the cutter carriage 32 is moved to the left or right depending on the shape to be cut from the recording paper S. Also, with the tip of the cutter blade 42B penetrating the recording paper S, the cutter roller 34 moves the recording paper S forward or backward depending on the shape to be cut from the recording paper S. This makes it possible to cut the recording paper S into any shape.
[0044] Furthermore, when the recording paper S is cut by the cutter blade 42B, the cutter blade 42B and the recording paper S move relative to each other in the forward, backward, left, and right directions. As described above, the cutter 42 is rotatably supported with respect to the housing 41. Therefore, when the cutter blade 42B and the recording paper S move relative to each other, the cutter 42 rotates in accordance with the direction of the relative movement.
[0045] <Conveying Section> The transport unit 7 is the part that transports the recording paper S on which images have been recorded in the recording unit 2. As shown in Figure 2, the transport unit 7 is equipped with a transport path 50 on which the recording paper S is transported. The transport path 50 has a paper discharge path 53, a reversal transport path 54, and a transition path 55.
[0046] Furthermore, the transport unit 7 includes a first switchback roller 64, an upstream path roller 65, a second switchback roller 66, and a downstream path roller 67. Rollers 64 to 67 are rollers for transporting the recording paper S along the transport path 50. In addition, the transport rollers 15 and 16 that constitute the recording unit 2 and the cutting unit roller 34 that constitutes the cutting unit 6 also serve as rollers that constitute the transport unit 7.
[0047] Rollers 64 to 67 are all rollers whose axial direction is in the left-right direction. Rollers 64 to 67 are driven and rotated by the roller drive device 107 shown in Figure 6 to transport the recording paper S. The roller drive device 107 has one or more motors for driving the rollers 61 to 63 and each roller that constitutes the transport section 7. The roller drive device 107 also includes gears, etc., that connect the one or more motors to each roller. Each motor of the roller drive device 107 may be provided for one roller, or it may be provided in common for two or more rollers.
[0048] <Paper output path, reversal transport path, first switchback roller> The paper output path 53 is the path for outputting the recording paper S, on which an image has been recorded in the recording unit 2, to the paper output tray 3. The paper output path 53 extends forward from the recording unit 2 to the paper output tray 3. The inversion transport path 54 is the path for transporting the recording paper S, on which an image has been recorded in the recording unit 2, back to the recording unit 2 after inverting its front and back sides.
[0049] The reverse transport path 54 includes a path that branches off from a branching section 53A located between the recording unit 2 and the output tray 3 of the output paper path 53. The reverse transport path 54 extends backward from the branching section 53A, passing below the recording unit 2, and merges with the cassette paper feed path 52 at the merging section 52A. The merged reverse transport path 54 and the cassette paper feed path 52 then merge with the tray paper feed path 51 at the merging section 51A. The merged reverse transport path 54, cassette paper feed path 52, and tray paper feed path 51 then extend to the recording unit 2.
[0050] Furthermore, a guide member 71 is provided at the branching section 53A. The guide member 71 is movable between a reversal guide position shown by a solid line in Figure 2 and a paper discharge guide position shown by a dashed line in Figure 2. The reversal guide position is the position when guiding the recording paper S from the paper discharge path 53 to the reversal transport path 54. The paper discharge guide position is the position when guiding the recording paper S along the paper discharge path 53. The guide member 71 is also biased from the paper discharge guide position toward the reversal guide position by a spring (not shown).
[0051] The first switchback roller 64 is located downstream of the branching point 53A of the paper discharge path 53. In other words, the first switchback roller 64 is located forward of the branching point 53A of the paper discharge path 53. The transport rollers 15, 16 and the first switchback roller 64 enable the transport of the recording paper S on which images have been recorded in the recording unit 2 along the paper discharge path 53.
[0052] When the recording paper S is transported forward along the paper output path 53, the guide member 71 is pushed by the recording paper S and moves from the inversion guide position towards the paper output guide position against the biasing force of a spring (not shown). Therefore, the recording paper S can be transported ahead of the guide member 71. In addition, the recording paper S on which an image has been recorded in the recording unit 2 can be transported to the paper output tray 3. Furthermore, a paper sensor 74 for detecting the recording paper S is positioned behind the first switchback roller 64.
[0053] Furthermore, when the recording paper S on which an image has been recorded in the recording unit 2 is transported by the first switchback roller 64 until the rear end of the recording paper S reaches in front of the guide member 71, the guide member 71 is no longer pressed by the recording paper S. Then, the guide member 71 returns to the reverse guide position due to the biasing force of a spring (not shown). After that, the roller drive device 107 rotates the first switchback roller 64 in the opposite direction to transport the recording paper S backward. In other words, a switchback can be performed to swap the front and rear ends of the recording paper S heading from the recording unit 2 to the cutting unit 6. When the recording paper S is transported backward, it is guided by the guide member 71 located in the reverse guide position and transported to the reverse transport path 54. Here, additional rollers for transporting the recording paper S may be arranged in the reverse transport path 54.
[0054] <Migration path> The transition route 55 includes an upstream route 55A, a switchback route 55B, and a downstream route 55C.
[0055] <Upstream Route> The upstream path 55A is a transport path for transporting the recording paper S to the switchback path 55B. The upstream path 55A is located upstream of the switchback path 55B in the transition path 55. The upstream path 55A branches off from the branching point 54A of the reversing transport path 54. The branching point 54A is located between the junction 52A with the cassette paper feed path 52 and the junction 51A with the tray paper feed path 51 in the reversing transport path 54. In other words, the branching point 54A is located above the junction 52A and below the junction 51A. The upstream path 55A extends rearward from the branching point 54A. Also, the upstream path 55A is located below the tray paper feed path 51. The upstream path 55A extends downward toward the manual feed tray 4.
[0056] Furthermore, a guide member 81 is positioned in the upstream path 55A. The guide member 81 is movable in the front-rear direction between a first position and a second position by a moving mechanism (not shown). The first position is the position shown by the solid line in Figure 2. The second position is the position forward of the first position, shown by the dashed line in Figure 2.
[0057] The guide member 81 has a guide surface at its front that guides the conveyed recording paper S. The guide surface extends in the vertical direction. When the guide member 81 is in the first position, the recording paper S that has been conveyed along the reversal conveyance path 54 is guided by the guide surface of the guide member 81. Also, when the guide member 81 is in the first position, the guide surface of the guide member 81 forms part of the rear wall of the path that conveys the recording paper S toward the recording unit 2. Therefore, the recording paper S is conveyed along the reversal conveyance path 54. When the guide member 81 is in the second position, the recording paper S that has been conveyed along the reversal conveyance path 54 passes below the guide member 81. Therefore, the recording paper S is conveyed to the upstream path 55A.
[0058] <Switchback route> The switchback route 55B is a transport path that performs a switchback on the recording paper S that has been transported from the upstream route 55A and transports it toward the downstream route 55C.
[0059] The switchback path 55B is formed by the portion of the tray forming member 8 that is below the manual feed tray 4. Therefore, the switchback path 55B is located behind the upstream path 55A and below the manual feed tray 4. The switchback path 55B extends inclined with respect to the front-to-back direction, sloping downwards as it moves forward. In other words, the transport path for transporting the recording paper S in the switchback path 55B extends inclined with respect to the horizontal plane, sloping downwards towards the front. It can also be said that the switchback path 55B extends along the surface on which the recording paper S is placed in the manual feed tray 4.
[0060] Furthermore, a portion of the switchback path 55B is defined by the media support surface 8A and the opposing surface 8B of the tray forming member 8. The media support surface 8A is formed by the lower portion of the tray forming member 8 and is a surface that supports the recording paper S from below. The opposing surface 8B is formed by the upper portion of the tray forming member 8. In other words, the opposing surface 8B is formed by the portion of the tray forming member 8 that acts as a partition separating the manual feed tray 4 from the switchback path 55B. The opposing surface 8B faces the media support surface 8A. A portion of the front of the recording paper S located in the switchback path 55B is covered by the media support surface 8A and the opposing surface 8B.
[0061] Furthermore, a portion of the rear of the recording paper S located in the switchback path 55B is exposed. In other words, a portion of the recording paper S is configured to protrude behind the rear end of the manual feed tray 4 in the switchback path 55B. It can also be said that a portion of the recording paper S is configured to protrude above the upper end of the manual feed tray 4 in the switchback path 55B. In short, the switchback path 55B is provided with an opening that allows a portion of the recording paper S to protrude to the outside. A paper sensor 75 for detecting the recording paper S is also positioned in front of the switchback path 55B.
[0062] <Downstream Route> The downstream path 55C is a transport path for transporting the recording paper S transported from the switchback path 55B to the cutting section 6. The downstream path 55C is located downstream of the switchback path 55B in the transition path 55. The downstream path 55C has a path section 55C1 and a path section 55C2.
[0063] The path section 55C1 is located in front of and below the switchback path 55B. Furthermore, the path section 55C1 is located below the upstream path 55A. The path section 55C1 extends from a position in front of the switchback path 55B to the upper surface of the support member 35. Additionally, the path section 55C1 extends in a direction inclined with respect to the front-to-back direction, becoming downward as it approaches the front. In other words, the path section 55C1 extends inclined with respect to the horizontal plane, becoming downward as it approaches the front.
[0064] The path portion 55C2 is formed by the portion of the upper surface of the support member 35 that is located in front of the path portion 55C1 and behind the cut portion 6. The path portion 55C2 extends from the front and lower end of the path portion 55C1 to the cut portion 6, substantially parallel to the front-to-back direction.
[0065] Furthermore, a guide member 72 is positioned between the upstream path 55A and path section 55C1 and the switchback path 55B in the front-rear direction. The guide member 72 is configured to be movable between a downstream guide position shown by a solid line in Figure 2 and an upstream guide position shown by a dashed line in Figure 2. The downstream guide position is the position when guiding the recording paper S from the switchback path 55B to the path section 55C1. The upstream guide position is the position when guiding the recording paper S from the upstream path 55A to the switchback path 55B. The guide member 72 is also biased from the upstream guide position toward the downstream guide position by a spring or the like (not shown).
[0066] <Upstream path roller, second switchback roller, downstream path roller> The upstream path roller 65 is located in the upstream path 55A. The second switchback roller 66 is located in the switchback path 55B. The downstream path roller 67 is located in the path portion 55C1 of the downstream path 55C.
[0067] The roller drive unit 107 drives the upstream path roller 65 and the second switchback roller 66, which are rotated in one direction. As a result, the recording paper S is transported from the upstream path 55A to the switchback path 55B. The guide member 72 is pushed by the recording paper S being transported from the upstream path 55A to the switchback path 55B. Therefore, the guide member 72 moves from the downstream guide position to the upstream guide position against the biasing force of a spring (not shown). When the rear end of the recording paper S being transported from the upstream path 55A to the switchback path 55B passes the guide member 72, the guide member 72 is no longer pushed by the recording paper S. Then, the guide member 72 returns to the downstream guide position due to the biasing force of a spring (not shown).
[0068] Furthermore, the roller drive device 107 drives the second switchback roller 66, causing it to rotate in the opposite direction to the one described above. As a result, the recording paper S on the switchback path 55B is fed forward and downward. The recording paper S fed out from the switchback path 55B is guided by the guide member 72 located at the downstream guide position. Consequently, the recording paper S is transported from the switchback path 55B to the path portion 55C1 of the downstream path 55C.
[0069] As explained above, the second switchback roller 66 can perform a switchback to swap the front and rear ends of the recording paper S being transported toward the cutting section 6 in the upstream path 55A. In other words, the second switchback roller 66 can perform a switchback so that the rear end of the recording paper S being transported toward the cutting section 6 in the upstream path 55A becomes the front end of the recording paper S being transported toward the cutting section 6 in the downstream path 55C.
[0070] When the downstream path roller 67 is driven by the roller drive device 107, the recording paper S that has been transported to path section 55C1 is transported through path sections 55C1 and 55C2 to the cutting section 6.
[0071] <Electrical configuration of the printer> Next, the electrical configuration of printer 1 will be described. As shown in Figure 6, printer 1 is equipped with a control unit 100. The control unit 100 includes a CPU 101, ROM 102, RAM 103, memory 104, ASIC 105, 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.
[0072] The control unit 100 controls the motors of the head carriage motor 106, head 13, roller drive unit 107, cutter carriage motor 108, lifting device 47, switching motor 83, etc. The control unit 100 also receives signals from sensor 33 and paper sensors 73-75.
[0073] In addition to the configuration described above, printer 1 is also equipped with an operation panel 99. The operation panel 99 has a display unit and an operation unit. The display unit is, for example, a liquid crystal display. The operation unit is, for example, hard keys, a touch panel provided on the display unit, etc. Under the control of the control unit 100, various screens are displayed on the display unit of the operation panel 99. Signals corresponding to user operations on the operation unit of the operation panel 99 are transmitted from the operation panel 99 to the control unit 100.
[0074] Furthermore, the control unit 100 may be configured such that only the CPU 101 performs the various processing. Alternatively, the control unit 100 may be configured such that only the ASIC 105 performs the various processing. Alternatively, the control unit 100 may be configured such that the CPU 101 and the ASIC 105 cooperate in performing the various processing. Alternatively, the control unit 100 may be configured such that one CPU 101 performs the processing independently. Alternatively, the control unit 100 may be configured such that multiple CPUs 101 share the processing responsibilities. Alternatively, the control unit 100 may be configured such that one ASIC 105 performs the processing independently. Alternatively, the control unit 100 may be configured such that multiple ASICs 105 share the processing responsibilities.
[0075] <Control during recording> Next, we will describe the control by the control unit 100 when the printer 1 records an image onto the recording paper S and cuts the recording paper S on which the image has been recorded.
[0076] Printer 1 can perform normal single-sided recording, normal double-sided recording, cut single-sided recording, and cut double-sided recording. Normal single-sided recording is an operation in which an image is recorded on only one side of the recording paper S and the recording paper S is not cut at the cutting unit 6. Normal double-sided recording is an operation in which an image is recorded on both sides of the recording paper S and the recording paper S is not cut at the cutting unit 6. Cut single-sided recording is an operation in which an image is recorded on only one side of the recording paper S and the recording paper S is cut at the cutting unit 6. Cut double-sided recording is an operation in which an image is recorded on both sides of the recording paper S and the recording paper S is cut at the cutting unit 6.
[0077] <Control during normal single-sided recording> The control unit 100 performs processing according to the flowchart in Figure 7(a) when performing normal single-sided recording. The printer 1 can perform normal single-sided recording on one sheet of recording paper S. When performing normal single-sided recording on one sheet of recording paper S, the processing according to the flowchart in Figure 7(a) is started by inputting a recording instruction signal that instructs normal single-sided recording. Inputting a recording instruction signal that instructs normal single-sided recording can be done, for example, by operating the operation panel 99 or a PC connected to the printer 1.
[0078] Furthermore, the printer 1 can perform normal single-sided recording on multiple sheets of recording paper S in succession. When the control unit 100 performs normal single-sided recording on multiple sheets of recording paper S in succession, it processes each of the multiple sheets of recording paper S according to the flowchart in Figure 7(a). The processing according to the flowchart in Figure 7(a) for the first sheet of recording paper S on which an image is recorded begins when a recording instruction signal indicating normal single-sided recording is input. The processing according to the flowchart in Figure 7(a) for the second and subsequent sheets of recording paper S on which images are recorded begins at timings that will be explained later.
[0079] To explain the flowchart in Figure 7(a) in detail, the control unit 100 first performs the paper feeding process (S101). In the S101 paper feeding process, the control unit 100 controls the roller drive device 107 to supply recording paper S from the manual feed tray 4 to the recording unit 2. Specifically, as shown in Figure 8(a), the control unit 100 causes the tray feed roller 61 to supply recording paper S from the manual feed tray 4 to the recording unit 2 through the tray feed path 51.
[0080] Alternatively, in the S101 paper feeding process, the control unit 100 controls the roller drive device 107 to supply recording paper S from the paper cassette 5 to the recording unit 2. Specifically, as shown in Figure 8(b), the control unit 100 causes the pickup roller 62 and the cassette paper feed roller 63 to supply recording paper S from the paper cassette 5 to the recording unit 2 through the cassette paper feed path 52.
[0081] Whether to supply the recording paper S from the manual feed tray 4 or the paper cassette 5 is determined, for example, based on a recording instruction, setting information pre-stored in the memory 104, etc.
[0082] Next, the control unit 100 performs recording processing (S102). In the recording processing of S102, the control unit 100 repeatedly performs recording path processing and recording transport processing to record an image on the recording paper S.
[0083] The recording path processing is a process in which ink is ejected from multiple nozzles 10 toward the recording paper S while moving the head carriage 11 to the left or to the right. The control unit 100 controls the head carriage motor 106 to move the head carriage 11 to the left or to the right during the recording path processing. The control unit 100 also controls the head 13 to eject ink from multiple nozzles 10 toward the recording paper S during the recording path processing.
[0084] The recording and transport process involves controlling the roller drive unit 107 to transport the recording paper S forward a predetermined distance on the transport rollers 15 and 16.
[0085] During recording in the recording unit 2, the recording paper S is transported along the tray feeding path 51, the top surface of the platen 14, and the paper discharge path 53.
[0086] Next, the control unit 100 performs the recording and paper ejection process (S103). In the recording and paper ejection process of S103, the control unit 100 controls the roller drive device 107 to transport the recording paper S on which the image is recorded to the paper ejection tray 3. Specifically, the control unit 100 uses the transport rollers 15, 16 and the first switchback roller 64 to transport the recording paper S forward to the paper ejection tray 3.
[0087] Next, the control unit 100 determines whether or not it is necessary to record an image on the next recording sheet S (S104). If it is necessary to record an image on the next recording sheet S (S104: YES), the control unit 100 starts processing for the next recording sheet S (S105). The processing started in S105 is the processing for the next recording sheet S according to the flowchart in Figure 7(a). Then, the control unit 100 finishes processing for the current recording sheet S according to the flowchart in Figure 7(a). If it is not necessary to record an image on the next recording sheet S (S104: NO), the control unit 100 finishes processing for the current recording sheet S according to the flowchart in Figure 7(a) without executing the process in S105.
[0088] <Control during normal double-sided recording> The control unit 100 performs processing according to the flowchart in Figure 7(b) when performing normal double-sided recording. The printer 1 can perform normal double-sided recording on a single sheet of recording paper S. When performing normal double-sided recording on a single sheet of recording paper S, the processing according to the flowchart in Figure 7(b) is initiated by the input of a recording instruction signal that instructs normal double-sided recording. The input of a recording instruction signal that instructs normal double-sided recording can be performed, for example, by operating the operation panel 99 or a PC connected to the printer 1.
[0089] Furthermore, printer 1 can perform normal double-sided recording on multiple sheets of recording paper S in succession. When performing normal double-sided recording on multiple sheets of recording paper S in succession, control unit 100 processes each of the multiple sheets of recording paper S according to the flowchart in Figure 7(b). The processing according to the flowchart in Figure 7(b) for the first sheet of recording paper S on which an image is recorded begins when a recording instruction signal indicating normal double-sided recording is input. The processing according to the flowchart in Figure 7(b) for the second and subsequent sheets of recording paper S on which images are recorded begins at timings that will be explained later.
[0090] To explain the flowchart in Figure 7(b) in detail, the control unit 100 performs the same paper feeding process as in S101 (S201). Next, the control unit 100 performs the first recording process (S202). The first recording process in S202 is the same process as the recording process in S102. The first recording process records an image on one side of the recording paper S.
[0091] Next, the control unit 100 performs a paper inversion process (S203). In the paper inversion process in S203, the control unit 100 controls the roller drive device 107 to invert the recording paper S, on which an image is recorded on one side, so that it is fed back to the recording unit 2. Specifically, the control unit 100 causes the transport rollers 15, 16 and the first switchback roller 64 to transport the recording paper S forward.
[0092] Then, as shown in Figure 9(a), the control unit 100 transports the recording paper S until the rear end Eb of the recording paper S is in front of the branching section 53A. At this point, when the first recording process in S202 is completed, the recording paper S is detected by the paper sensor 74. The control unit 100 transports the recording paper S forward until the recording paper S is no longer detected by the paper sensor 74. This allows the recording paper S to be transported until the end Eb of the recording paper S is in front of the branching section 53A.
[0093] The control unit 100 then rotates the first switchback roller 64 in the reverse direction to transport the recording paper S backward. In other words, it performs a switchback on the recording paper S. As a result, the recording paper S is guided by the guide member 71 located at the inversion guide position, as shown by Sa in Figure 9(b), and transported from the paper discharge path 53 to the inversion transport path 54. The guide member 81 is also located at the first position. Therefore, the recording paper S transported along the inversion transport path 54 is supplied back to the recording unit 2 with its front and back sides reversed, as shown by Sb in Figure 9(b).
[0094] Next, the control unit 100 performs a second recording process (S204). The second recording process in S204 is the same as the recording process in S102. The second recording process records an image on the other side of the recording paper S. The control unit 100 then performs a recording paper ejection process similar to that in S103 (S205).
[0095] The control unit 100 then determines whether or not it is necessary to record an image on the next recording sheet S (S206). If it is necessary to record an image on the next recording sheet S (S206: YES), the control unit 100 starts processing for the next recording sheet S (S207). The processing started in S207 is the processing for the next recording sheet S according to the flowchart in Figure 7(b). Then, the control unit 100 finishes processing for the current recording sheet S according to the flowchart in Figure 7(b). If it is not necessary to record an image on the next recording sheet S (S206: NO), the control unit 100 finishes processing for the current recording sheet S according to the flowchart in Figure 7(b) without executing the process in S207.
[0096] <Control during single-sided recording after cutting> The control unit 100 performs processing according to the flowchart in Figure 7(c) when performing cut-side-side recording. The printer 1 can perform cut-side-side recording on a single sheet of recording paper S. When performing cut-side-side recording on a single sheet of recording paper S, the processing according to the flowchart in Figure 7(c) is initiated by the input of a recording instruction signal that instructs cut-side-side recording. The input of a recording instruction signal that instructs cut-side-side recording can be performed, for example, by operating the operation panel 99, a PC connected to the printer 1, etc.
[0097] Furthermore, the printer 1 can perform continuous single-sided cutting recording on multiple sheets of recording paper S. When the control unit 100 performs continuous single-sided cutting recording on multiple sheets of recording paper S, it processes each of the multiple sheets of recording paper S according to the flowchart in Figure 7(c). The processing according to the flowchart in Figure 7(c) for the first sheet of recording paper S on which an image is recorded and then cut begins when a recording instruction signal indicating single-sided cutting is input. The processing according to the flowchart in Figure 7(c) for the second and subsequent sheets of recording paper S on which images are recorded and then cut begins at timings that will be explained later.
[0098] To explain the flowchart in Figure 7(c) in detail, the control unit 100 executes the same processes as S101 and S102, as in S301 and S302.
[0099] In the recording process for normal single-sided recording and the first and second recording processes for normal double-sided recording described above, the control unit 100 causes image P to be recorded on the recording paper S, for example, as shown in Figure 10(a). Image P is an image corresponding to the image data input along with the recording instruction. In contrast, in the recording process of S302, the control unit 100 causes mark M to be recorded on the recording paper S in addition to image P, for example, as shown in Figure 10(b).
[0100] Mark M is used to adjust the cutting position when cutting the recording paper S. In Figure 10(b), four marks M are recorded at the four corners of the recording paper S. However, the number of marks M may be 1 to 3 or 5 or more. Also, the position where the marks M are recorded does not have to be at the four corners of the recording paper S. Furthermore, although the marks M are L-shaped in Figure 10(b), the marks M may have a different shape.
[0101] Next, the control unit 100 executes the transport process (S303). In the transport process in S303, the control unit 100 performs the process according to the flowchart in Figure 11. To explain in detail, the control unit 100 first determines whether or not there are any waiting recording sheets S (S501).
[0102] In this embodiment, the waiting recording sheet S in S501 is the recording sheet S waiting at the switchback position of the switchback path 55B. The control unit 100 determines that there is a waiting recording sheet S in S501 if, for example, the second transport process in S506 (described later) for the previous recording sheet S has not been started. On the other hand, the control unit 100 determines that there is no waiting recording sheet S in S501 if, for example, the second transport process in S506 (described later) for the previous recording sheet S has been started.
[0103] The control unit 100 waits if there is any waiting recording paper S (S501: YES). If there is no waiting recording paper S (S501: NO), the control unit 100 then executes the first transport process (S502). In the first transport process of S502, the control unit 100 transports the recording paper S to the switchback position of the switchback path 55B.
[0104] Specifically, the control unit 100 controls the roller drive unit 107 to transport the recording paper S forward using the transport rollers 15, 16 and the first switchback roller 64. At this time, as shown in Figure 9(a), the control unit 100 transports the recording paper S until the rear end Eb of the recording paper S is in front of the branching section 53A. That is, the control unit 100 transports the recording paper S forward until the recording paper S is no longer detected by the paper sensor 74. In this embodiment, the position of the recording paper S when it is no longer detected by the paper sensor 74 corresponds to the "switchback position" and the "first switchback position" of the present invention.
[0105] The control unit 100 then controls the switching motor 83 to move the guide member 81 to the second position. The control unit 100 then controls the roller drive device 107 to transport the recording paper S backward to the first switchback roller 64. That is, it causes a switchback to be performed on the recording paper S. As a result, the recording paper S is guided by the guide member 71 located in the reverse guidance position and transported from the paper discharge path 53 to the reverse transport path 54. Sc in Figure 12(a) shows the recording paper S being transported from the paper discharge path 53 to the reverse transport path 54. Also, the guide member 81 is in the second position. Therefore, the recording paper S being transported along the reverse transport path 54 is transported from the reverse transport path 54 to the upstream path 55A. Here, Sd in Figure 12(a) shows the recording paper S being transported from the reverse transport path 54 to the upstream path 55A.
[0106] Furthermore, when the recording paper S is transported forward to the position shown in Figure 9(a), the edge Ea of the recording paper S is the front end of the recording paper S facing from the recording unit 2 to the cutting unit 6. The opposite end Eb of the recording paper S is the rear end of the recording paper S facing from the recording unit 2 to the cutting unit 6. On the other hand, when the recording paper S is transported backward from the position shown in Figure 9(a), the edge Eb is the front end of the recording paper S facing from the recording unit 2 to the cutting unit 6. The edge Ea is the rear end of the recording paper S facing from the recording unit 2 to the cutting unit 6. In other words, the front and rear ends of the recording paper S facing from the recording unit 2 to the cutting unit 6 are swapped when transporting to the position shown in Figure 9(a) and when transporting from the position shown in Figure 9(a). In this embodiment, the combined paper discharge path 53 and the first switchback roller 64 correspond to the "switchback section" and "first switchback section" of the present invention.
[0107] The control unit 100 then causes the upstream path roller 65 and the second switchback roller 66 to transport the recording paper S to the switchback position of the switchback path 55B. At this point, just before the edge Eb of the recording paper S reaches the switchback path 55B, the paper sensor 75 begins to detect the recording paper S. Then, just before the edge Ea of the recording paper S reaches the switchback path 55B, the edge Ea passes below the paper sensor 75, and the paper sensor 75 no longer detects the recording paper S. The position of the recording paper S when the paper sensor 75 no longer detects the recording paper S is the switchback position of the switchback path 55B. After the paper sensor 75 detects the recording paper S, the control unit 100 causes the upstream path roller 65 and the second switchback roller 66 to transport the recording paper S until a certain amount of time has elapsed since the recording paper S was no longer detected. This allows the recording paper S to be transported to the switchback position of the switchback path 55B. Se in Figure 12(a) shows the recording paper S in the process of being transported to the switchback position of the switchback path 55B.
[0108] In this embodiment, the switchback position on the switchback path 55B corresponds to the "switchback position" and the "second switchback position" of the present invention. The recording sheet S shown by the dashed line in Figure 2 represents the recording sheet S located at the second switchback position.
[0109] Returning to Figure 11, the control unit 100 then determines whether or not it is necessary to record and cut an image on the next recording sheet S (S503). If the control unit 100 determines that it is necessary to record and cut an image on the next recording sheet S (S503: YES), it starts processing for the next recording sheet S (S504). Then, the control unit 100 proceeds to S505. The processing started in S504 is the processing for the next recording sheet S according to the flowchart in Figure 7(c). If the control unit 100 determines that it is not necessary to record and cut an image on the next recording sheet S (S505: NO), it proceeds to S505 without executing the processing in S504.
[0110] In S505, the control unit 100 determines whether or not the recording paper S is being cut at the cutting unit 6. If the cutting unit 6 is cutting the recording paper S (S505: YES), the control unit 100 waits. That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not cutting the recording paper S (S505: NO), the control unit 100 executes the second transport process (S506). After the second transport process in S506, the control unit 100 returns to the flowchart in Figure 7(c).
[0111] In the second transport process in S506, the control unit 100 controls the roller drive unit 107 to transport the recording paper S to the cutting unit 6. Specifically, the control unit 100 rotates the second switchback roller 66 in the opposite direction to that used in the first transport process. As a result, the recording paper S is guided by the guide member 72 located at the downstream guide position and transported from the switchback path 55B to the path portion 55C1 of the downstream path 55C. In other words, a switchback is performed for the recording paper S. Sf in Figure 12(b) shows the recording paper S being transported from the switchback path 55B to the path portion 55C1.
[0112] The control unit 100 then causes the downstream path roller 67 and the cutting section roller 34 to transport the recording paper S to the cutting section 6. More specifically, the control unit 100 transports the recording paper S to the cutting section 6 through the path sections 55C1 and 55C2. Sg in Figure 12(b) shows the recording paper S in transit to the cutting section 6. By being transported as described above, the recording paper S is transported to the cutting section 6 with the image recording surface from the recording process in S302 facing upwards.
[0113] Furthermore, when transporting the recording paper S to the switchback path 55B, end Eb is the front end of the recording paper S heading from the recording section 2 to the cutting section 6. End Ea is the rear end of the recording paper S heading from the recording section 2 to the cutting section 6. On the other hand, when transporting the recording paper S from the switchback path 55B to the cutting section 6, end Ea is the front end of the recording paper S heading from the recording section 2 to the cutting section 6. End Eb is the rear end of the recording paper S heading from the recording section 2 to the cutting section 6. In other words, the front and rear ends of the recording paper S heading from the recording section 2 to the cutting section 6 are swapped when transporting to the switchback path 55B and when transporting from the switchback path 55B. In this embodiment, the switchback path 55B and the second switchback roller 66 together correspond to the "switchback section" and "second switchback section" of the present invention.
[0114] Returning to Figure 7(c), the control unit 100 then performs mark detection processing (S304). In the mark detection processing of S304, the control unit 100 causes the sensor 33 to sequentially detect the four marks M on the recording paper S. Specifically, the control unit 100 controls the cutter carriage motor 108 to move the cutter carriage 32 to the left and right so that each mark M can be detected by the sensor 33. The control unit 100 also controls the roller drive device 107 to move the recording paper S forward and backward on the cutting roller 34 so that each mark M can be detected by the sensor 33. The control unit 100 then acquires information on the left-right position of the cutter carriage 32 and the front-back position of the recording paper S when each mark M is detected by the sensor 33.
[0115] The control unit 100 then performs the cutting process (S305). In the cutting process of S305, the control unit 100 controls the lifting device 47 to lower the cutter cartridge 31. Specifically, the control unit 100 lowers the cutter cartridge 31 until the cutter blade 42B of the cutter 42 penetrates the recording paper S. Then, the control unit 100 moves the cutter carriage 32 and moves the recording paper S to the cutting roller 34, causing the cutter 42 to cut the recording paper S. At this time, the control unit 100 moves the cutter carriage 32 and the recording paper S according to the position of the image recording area on the recording paper S. Also, when cutting the recording paper S, the control unit 100 adjusts the cutting position of the recording paper S based on the information acquired in S304. Then, with the above control, the control unit 100 causes the cutter 42 to cut the recording paper S along the outline of the recorded image P, for example, as shown by the dashed line in Figure 10(b).
[0116] After the cutting process in S305, the control unit 100 performs the cut and paper ejection process (S306). In the cut and paper ejection process in S306, the control unit 100 controls the roller drive device 107 to eject the recording paper S, which has been cut in the cutting unit 6, forward to the cutting unit roller 34. With the completion of the cut and paper ejection process in S306, the process according to the flowchart in Figure 7(c) is completed.
[0117] <Control during recording on both sides of a cut surface> The control unit 100 performs processing according to the flowchart in Figure 7(d) when performing double-sided cutting recording. The printer 1 can perform double-sided cutting recording on a single sheet of recording paper S. When performing double-sided cutting recording on a single sheet of recording paper S, the processing according to the flowchart in Figure 7(d) is initiated by the input of a recording instruction signal that instructs double-sided cutting recording. The input of a recording instruction signal that instructs double-sided cutting recording can be performed, for example, by operating the operation panel 99 or a PC connected to the printer 1.
[0118] Furthermore, the printer 1 can perform continuous double-sided recording on multiple sheets of recording paper S. When the control unit 100 performs continuous single-sided recording on multiple sheets of recording paper S, it processes each of the multiple sheets of recording paper S according to the flowchart in Figure 7(d). The processing according to the flowchart in Figure 7(d) for the first sheet of recording paper S on which an image is recorded and then cut begins when a recording instruction signal indicating double-sided recording is input. The processing according to the flowchart in Figure 7(d) for the second and subsequent sheets of recording paper S on which images are recorded and then cut begins at timings that will be explained later.
[0119] To explain the flowchart in Figure 7(d) in detail, the control unit 100 executes the same processes as S201 to S204, specifically S401 to S404. However, in the first recording process of S402, the control unit 100 records the image P on one side of the recording paper S, for example, as shown in Figure 10(a). Furthermore, in the second recording process of S404, the control unit 100 records the image P and the mark M on the other side of the recording paper S, for example, as shown in Figure 10(b).
[0120] Next, the control unit 100 executes the same processes as S303 to S306, from S405 to S408, and completes the process according to the flowchart in Figure 7(d). The recording paper S is transported as described above by the transport process in S405, and is transported to the cutting unit 6 with the image recording surface from the second recording process in S404 facing upwards.
[0121] Furthermore, in this embodiment, the control unit 100 performs the processing as described above to cause single-sided recording and double-sided recording to be performed on multiple sheets of recording paper S. Therefore, as shown in Figure 13(a), at the same time that a recording sheet Sh is cut in the cutting unit 6, an image may be recorded on another recording sheet Si in the recording unit 2. In addition, the transport path 50 is configured so that the recording sheet Si being recorded in the recording unit 2 and the recording sheet Sh being cut in the cutting unit 6 do not come into contact. In the example of Figure 13(a), the recording sheet Sh corresponds to the "first recording medium" of the present invention. Also, in the example of Figure 13(a), the recording sheet Si corresponds to the "second recording medium" of the present invention.
[0122] However, it is not limited to the possibility that an image may be recorded on another sheet of paper in the recording unit 2 at the same time as an image is cut on a sheet of paper in the cutting unit 6. It is not necessary for an image to be recorded on another sheet of paper in the recording unit 2 at the same time as an image is cut on a sheet of paper in the cutting unit 6.
[0123] Furthermore, in this embodiment, as shown in Figure 13(b), the recording paper Sj located at the switchback position of the switchback path 55B does not come into contact with another recording paper Sk being cut at the cutting unit 6. Also, the recording paper Sj does not come into contact with another recording paper Sl being recorded with an image at the recording unit 2. In the example of Figure 13(b), the recording paper Sk corresponds to the "first recording medium" of the present invention. Also, in the example of Figure 13(b), the recording paper Sj corresponds to the "second recording medium" of the present invention. Also, in the example of Figure 13(b), the recording paper Sl corresponds to the "third recording medium" of the present invention.
[0124] <Effects> In this embodiment, while one recording sheet S is being cut in the cutting unit 6, another recording sheet S on which an image has been recorded in the recording unit 2 can be kept waiting at the switchback position. Therefore, after the cutting of the aforementioned recording sheet S is completed in the cutting unit 6, the other recording sheet S that has already been recorded and was kept waiting can be quickly transported to the cutting unit 6. As a result, the next recording sheet S is supplied to the cutting unit 6 quickly, improving the operational efficiency of the cutting unit 6. In addition, the recording unit 2 can transport the recorded recording sheet S to the waiting position regardless of the operational status of the cutting unit 6, thus improving the operational efficiency of the recording unit 2. Thus, image recording and cutting of multiple recording sheets S can be performed efficiently.
[0125] Furthermore, in this embodiment, the recording paper S waiting at the switchback position does not come into contact with the recording paper S being cut at the cutting unit 6. This prevents malfunctions caused by another recording paper S waiting at the switchback position coming into contact with the cutting of one recording paper S at the cutting unit 6.
[0126] Furthermore, in this embodiment, the recording paper S waiting at the switchback position does not come into contact with another recording paper S that is being recorded by the recording unit 2. This allows the recording unit 2 to record an image onto another recording paper S while the recording paper S is waiting at the switchback position. Moreover, it prevents problems caused by the recording paper S waiting at the switchback position coming into contact with the recording paper S during the recording process by the recording unit 2. As a result, it is possible to efficiently record and cut images onto multiple sheets of recording paper S.
[0127] <Variation> 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.
[0128] The flow of the cutting and transport process in single-sided cutting and double-sided cutting is not limited to that of the embodiments described above.
[0129] <Example 1> In Modification 1, the control unit 100 processes the cutting and transport process in S303 and S405 according to the flowchart in Figure 14. More specifically, the control unit 100 executes the processes S601 to S605, which are the same as S501 to S505 in the above embodiment. Then, if the cutting unit 6 is cutting the recording paper S (S605: YES), the control unit 100 waits. That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not cutting the recording paper S (S605: NO), the control unit 100 then determines whether the elapsed time T is equal to or greater than the drying time Td (S606).
[0130] In single-sided cutting recording, the elapsed time T is the time elapsed since the recording of the image on the recording paper S by the recording unit 2 in the recording process of S302 was completed. In double-sided cutting recording, the elapsed time T is the time elapsed since the recording of the image on the recording paper S by the recording unit 2 in the second recording process of S405 was completed. The drying time Td is the time that is expected to be required for the ink on the recording paper S on which the image has been recorded to dry. The drying time Td is determined in advance, for example, by experimentation, and is stored in memory 84.
[0131] The control unit 100 waits if the elapsed time T is less than the drying time Td (S606: NO). That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the elapsed time T is equal to or greater than the drying time Td (S606: YES), the control unit 100 performs the same second transport process as in S506 (S607).
[0132] In Modification 1, when the cutting of a certain recording sheet S is completed in the cutting unit 6, if the elapsed time T is equal to or greater than the drying time Td, another recording sheet S is transported to the cutting unit 6. This allows the cutting unit 6 to immediately cut the other, dried recording sheet S after the cutting of the previous recording sheet S is completed. In other words, by having the recorded recording sheet S wait in the standby position, drying time can be ensured while waiting for supply to the cutting unit 6.
[0133] On the other hand, if the elapsed time T is less than the drying time Td when the cutting of one recording sheet S is completed in the cutting unit 6, the other recording sheet S is transported to the cutting unit 6 after the elapsed time T has become equal to or greater than the drying time Td. This allows the ink adhering to the other recording sheet S to be sufficiently dried before it is cut in the cutting unit 6. As a result, ink is less likely to adhere to the cutter 42, cutting unit roller 34, etc. of the cutting unit 6. In addition, the degradation of the image quality of the recorded image caused by cutting the recording sheet S before the ink adhering to it has sufficiently dried can be suppressed.
[0134] <Modification 2> In Modification 2, the printer 1 can record an image on the recording paper S using a first recording mode and a second recording mode. The second recording mode is a recording mode in which less ink is used to record the same image data than in the first recording mode. The first recording mode is, for example, a recording mode for recording an image on glossy paper. The second recording mode is, for example, a recording mode for recording an image on plain paper. In Modification 2, along with a recording instruction signal, a signal indicating which recording mode, the first recording mode or the second recording mode, should be used for recording is input to the control unit 100.
[0135] In the modified example 2, the control unit 100 processes the cutting and transport process in S303 and S405 according to the flowchart in Figure 15. More specifically, the control unit 100 executes the processes S701 to S705, which are the same as S501 to S505 in the above embodiment. Then, if the cutting unit 6 is cutting the recording paper S (S705: YES), the control unit 100 waits. That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not cutting the recording paper S (S705: NO), the control unit 100 then determines whether or not it is in the first recording mode (S706).
[0136] If the first recording mode is selected (S706:YES), the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B for a predetermined time (S707). The control unit 100 then performs the second transport process, which is the same as S506 in the above-described embodiment (S708). If the high-speed recording cut-off mode is selected (S706:NO), the control unit 100 performs the second transport process without performing the process in S707 (S708).
[0137] In Modification 2, the conditions that the cutting unit 6 is cutting the recording paper S and that the system is in the first recording mode correspond to the "first condition" of the present invention. Furthermore, the conditions that the cutting unit 6 is not cutting the recording paper S and that the system is in the second recording mode correspond to the "second condition" of the present invention.
[0138] In the modified example 2, when the first condition is met, the recording paper S on which the image is recorded is made to wait at the switchback position of the switchback path 55B before being transported to the cutting section. On the other hand, when the second condition is met, the recording paper S on which the image is recorded is transported to the cutting section 6 without being made to wait at the switchback position of the switchback path 55B. This allows the recording paper S on which the image is recorded to be transported to the cutting section 6 appropriately according to the conditions.
[0139] Specifically, in Modification 2, the first condition includes the condition that the image was recorded in the first recording mode, which has a larger amount of ink adhesion than the second recording mode. This allows the recording paper S to be cut in the cutting unit 6 after the ink adhering to the recording paper S has dried. As a result, it is possible to make it less likely for ink to adhere to the cutter 42, cutting unit roller 34, etc. of the cutting unit 6. In addition, it is possible to suppress the deterioration of the image quality of the recorded image caused by cutting the recording paper S before the ink adhering to the recording paper S has dried sufficiently. Furthermore, in Modification 2, the second condition includes the condition that the image was recorded in the second recording mode, which has a smaller amount of ink adhesion than the second recording mode. This makes it possible to start cutting the recording paper S on which the image has been recorded as early as possible.
[0140] In variation 3, printer 1 can record images onto recording paper S and cut the recording paper S in both a normal recording and cutting mode and a high-speed recording and cutting mode. The high-speed recording and cutting mode completes the recording of images onto recording paper S and the cutting of recording paper S in a shorter time than the normal recording and cutting mode.
[0141] In the modified example 3, the control unit 100 processes the cutting and transport process in S303 and S405 according to the flowchart in Figure 16. More specifically, the control unit 100 executes the processes S801 to S805, which are the same as S501 to S505 in the above embodiment. Then, if the cutting unit 6 is cutting the recording paper S (S805: YES), the control unit 100 waits. That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not cutting the recording paper S (S805: NO), the control unit 100 then determines whether or not it is in normal recording cutting mode (S806).
[0142] If the control unit 100 is in normal recording cutoff mode (S806:YES), it causes the recording paper S to wait for a predetermined time at the switchback position of the switchback path 55B (S807). The control unit 100 then performs the second transport process similar to S506 in the above embodiment (S808). If the control unit 100 is in high-speed recording cutoff mode (S806:NO), it performs the second transport process without performing the process in S807 (S808).
[0143] In Modification Example 3, the conditions that the cutting unit 6 is cutting the recording paper S and that the system is in normal recording cutting mode correspond to the "first condition" of the present invention. Furthermore, the conditions that the cutting unit 6 is not cutting the recording paper S and that the system is in high-speed recording cutting mode correspond to the "second condition" of the present invention.
[0144] In the third modified example, when the first condition is met, the recording paper S on which the image is recorded is made to wait at the switchback position of the switchback path 55B before being transported to the cutting section. On the other hand, when the second condition is met, the recording paper S on which the image is recorded is transported to the cutting section 6 without being made to wait at the switchback position of the switchback path 55B. This allows the recording paper S on which the image is recorded to be transported to the cutting section 6 appropriately according to the conditions.
[0145] Specifically, in Modification 3, the first condition includes the condition that the normal recording and cutting mode is selected. This allows the recording paper S to be cut after the ink has dried sufficiently, when it is not required that the recording and cutting of the image be completed in a short time. As a result, it is possible to reduce the likelihood of ink adhering to the cutter 42, cutting roller 34, etc. of the cutting section 6. It is also possible to suppress the deterioration of the image quality of the recorded image caused by cutting the recording paper S before the ink adhering to the recording paper S has dried sufficiently. Furthermore, in Modification 3, the second condition includes the condition that the high-speed recording and cutting mode is selected. This allows the recording of the image and cutting of the recording paper S to be completed in a shorter time compared to the normal recording and cutting mode, when it is required that the recording and cutting of the image be completed in a short time.
[0146] <Modification 4> In the modified example 4, the control unit 100 performs processing according to the flowchart in Figure 17(a) when performing single-sided recording after cutting. More specifically, the control unit 100 performs the same processing S901 to S906 as S301 to S306 in the above embodiment. The control unit 100 then determines whether or not it is the first recording sheet S (S907). Here, the first recording sheet S is the first recording sheet S on which an image is recorded and cut out of a plurality of recording sheets S on which images are recorded consecutively and then cut out.
[0147] If it is the first recording sheet S (S907: YES), the control unit 100 displays a confirmation screen 120 as shown in Figure 17(c) on the display unit of the operation panel 99 (S908). Then, the control unit 100 terminates the process according to the flowchart in Figure 17(a). On the other hand, if it is not the first recording sheet S (S907: NO), the control unit 100 terminates the process according to the flowchart in Figure 17(a) without executing the process in S908.
[0148] The confirmation screen 120 is a screen for confirming with the user whether or not to continue recording and cutting images on multiple sheets of recording paper S. The confirmation screen 120 has a message section 121 and selection sections 122 and 123. The message section 121 is the part where a message is displayed to confirm with the user whether or not to continue recording and cutting images on multiple sheets of recording paper S. The selection section 122 is the part that the user selects when deciding to continue recording and cutting images on multiple sheets of recording paper S. The selection section 123 is the part that the user selects when deciding not to continue recording and cutting images on multiple sheets of recording paper S.
[0149] For example, the user checks the quality of the output produced by recording an image on the first recording sheet S and then cutting it. If the user determines that there are no problems with the quality of the output, they perform the operation to select the selection unit 122 on the operation panel 99. On the other hand, if the user determines that there are problems with the quality of the output, they perform the operation to select the selection unit 123 on the operation panel 99.
[0150] Furthermore, in the modified example 4, when performing double-sided cutting recording, the control unit 100 processes according to the flowchart in Figure 17(b). In detail, the control unit 100 executes the S1001 to S1008 processes, which are the same as S401 to S408 in the above-described embodiment. Subsequently, the control unit 100 executes the S1007 and S1008 processes, which are the same as S907 and S908.
[0151] Furthermore, in the modified example 4, the control unit 100 processes the cutting and transport processes in S903 and S1005 according to the flowchart in Figure 18. In detail, the control unit 100 executes the processes S1101 to S1104, which are the same as S501 to S504 in the above-described embodiment. Then, if it is not necessary to record an image on the next recording sheet S and cut it (S1103: NO), the control unit 100 proceeds to process S1105. Also, after processing S1104, the control unit 100 proceeds to process S1105.
[0152] In S1105, the control unit 100 determines whether or not it is the first recording sheet S. If it is the first recording sheet S (S1105: YES), the control unit 100 executes the second transport process (S1108). The second transport process in S1108 is the same process as the second transport process in S506 of the above embodiment. Then, the control unit 100 returns the process to the flowchart in Figure 17(a) or Figure 17(b).
[0153] If the control unit 100 is not the first recording sheet S (S1105: NO), it then determines whether the cutting unit 6 is currently cutting the recording sheet S (S1106). If the cutting unit 6 is currently cutting the recording sheet S (S1106: YES), the control unit 100 waits. That is, the control unit 100 has the recording sheet S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not currently cutting the recording sheet S (S1106: NO), the control unit 100 then determines whether a continuation operation has been performed on the operation unit of the operation panel 99 (S1107). A continuation operation is the operation in which the selection unit 122 of the confirmation screen 120 in Figure 17(c) is selected.
[0154] The control unit 100 waits if no further operation is performed on the operation panel 99 (S1107: NO). That is, the control unit 100 waits for the recording paper S to be placed at the switchback position of the switchback path 55B. If a further operation is performed on the operation panel 99 (S1107: YES), the control unit 100 proceeds to the second transport process in S1108.
[0155] Furthermore, when the operation to select the selection unit 123 is performed on the operation unit of the confirmation screen 120, the subsequent recording and cutting of images on the recording paper S may be stopped.
[0156] In Modification 4, the condition that it is the first recording sheet S corresponds to the "second condition" of the present invention. Furthermore, the condition that it is the second or later recording sheet S, and that the recording sheet S is being cut by the cutting unit 6, or that no further operation is being performed, corresponds to the "first condition" of the present invention. Here, the second or later recording sheet S refers to the recording sheet S that is the second or later among a plurality of recording sheets S on which images are continuously recorded and cut, and on which images are recorded and cut.
[0157] In Modification 4, when the first condition is met, the recording paper S on which the image is recorded is made to wait at the switchback position before being transported to the cutting section. On the other hand, when the second condition is met, the recording paper S on which the image is recorded is transported to the cutting section 6 without being made to wait at the switchback position. This allows the recording paper S on which the image is recorded to be transported to the cutting section 6 appropriately according to the conditions.
[0158] Specifically, in Modification 4, when the first recording sheet S is transported from the recording unit 2 to the cutting unit 6, the cutting unit 6 is not in the process of cutting another recording sheet S. In Modification 4, the first condition includes the condition that it is the first recording sheet S. Therefore, the first recording sheet S is transported to the cutting unit 6 without being held at the switchback position. This allows the cutting of the first recording sheet S at the cutting unit 6 to start as quickly as possible.
[0159] Furthermore, with respect to the second recording sheet S mentioned above, when it is being transported from the recording unit 2 to the cutting unit 6, the cutting unit 6 may be cutting another recording sheet S. In the modified example 4, the second condition includes the condition that it is the second or subsequent recording sheet S. Therefore, the second and subsequent recording sheets S can be made to wait at the switchback position. Then, after the cutting unit 6 has finished cutting the recording sheet S on which the image was recorded first, the recording sheet S can be transported from the switchback position to the cutting unit 6. As a result, the recording and cutting of images on multiple recording sheets S can be performed efficiently.
[0160] Furthermore, in Modification 4, the user checks the quality of the output generated by recording an image on the first recording sheet S and then cutting it. When the user determines that there are no problems with the quality of the output, they perform a continuation operation on the operation panel 99. In Modification 4, as described above, the second and subsequent recording sheets S can be kept waiting at the switchback position. Therefore, the second recording sheet S can be kept waiting at the switchback position until a continuation operation is performed. When a continuation operation is performed, the second recording sheet S can be transported from the switchback position to the cutting unit 6. As a result, cutting of the second recording sheet S at the cutting unit 6 can be started as quickly as possible after the continuation operation. In addition, if the quality of the output is poor, the recording of images on the second and subsequent recording sheets and cutting can be stopped. Therefore, the consumption of unnecessary ink and recording sheets S can be reduced.
[0161] <Modification 5> In Modification 5, when performing single-sided recording after cutting, the control unit 100 processes according to the flowchart in Figure 19(a). More specifically, the control unit 100 performs the same processes S1201 to S1206 as in S901 to S906 of Modification 4. Subsequently, the control unit 100 determines whether the first recording sheet S has been ejected (S1207).
[0162] If the first recording sheet S has not been ejected (S1207: NO), the control unit 100 displays a confirmation screen 120 as shown in Figure 17(c) on the operation panel 99 (S1208). Then, the control unit 100 terminates the process according to the flowchart in Figure 19(a). On the other hand, if the first recording sheet S has been ejected (S1207: YES), the control unit 100 terminates the process according to the flowchart in Figure 19(a) without executing the process in S1208.
[0163] Furthermore, in Modification 5, when performing double-sided cutting recording, the control unit 100 processes according to the flowchart in Figure 19(b). In detail, the control unit 100 executes the processes S1301 to S1308, which are the same as S1001 to S1008 in Modification 4. Subsequently, the control unit 100 executes the processes S1309 and S1310, which are the same as S1307 and S1308.
[0164] Furthermore, in the cutting and transport process of S1203 and S1305, the control unit 100 performs the processing according to the flowchart in Figure 20.
[0165] In more detail, the control unit 100 executes the processes S1401 to S1404, which are the same as those in the above-described embodiment. Then, if the control unit 100 determines in S1403 that recording and cutting of the next recording sheet S is not necessary (S1403: NO), it proceeds to S1405. Also, after the process in S1404, the control unit 100 proceeds to S1405.
[0166] In S1405, the control unit 100 determines whether or not the cutting unit 6 is currently cutting the recording paper S. If the cutting unit 6 is currently cutting the recording paper S (S1405: YES), the control unit 100 waits. That is, the control unit 100 has the recording paper S wait at the switchback position of the switchback path 55B. If the cutting unit 6 is not currently cutting the recording paper S (S1405: NO), the control unit 100 determines whether or not the first recording paper S has been ejected (S1406). Note that in S1405, when the process according to the flowchart in Figure 20 is the process for the first recording paper S, it is determined that the cutting unit 6 is not currently cutting the recording paper S.
[0167] If the first recording sheet S has not been ejected (S1406: NO), the control unit 100 proceeds to the second transport process in S1408. The second transport process in S1408 is the same as the second transport process in S506 of the above-described embodiment.
[0168] If the first recording sheet S has been ejected (S1406: YES), the control unit 100 determines whether a continuation operation has been performed on the operation panel 99 (S1407). If no continuation operation has been performed on the operation panel 99 (S1407: NO), the control unit 100 waits. That is, the control unit 100 has the recording sheet S wait at the switchback position of the switchback path 55B. If a continuation operation has been performed on the operation panel 99 (S1407: YES), the control unit 100 proceeds to the second transport process in S1408.
[0169] In Modification 5, the condition that the first record sheet S has been ejected corresponds to the "second condition" of the present invention. Furthermore, the condition that the state is other than the second condition corresponds to the "first condition" of the present invention.
[0170] In Modification 5, when the first condition is met, the recording paper S on which the image is recorded is made to wait at the switchback position before being transported to the cutting section. On the other hand, when the second condition is met, the recording paper S on which the image is recorded is transported to the cutting section 6 without being made to wait at the switchback position. This allows the recording paper S on which the image is recorded to be transported to the cutting section 6 appropriately according to the conditions.
[0171] Specifically, in Modification 5, the second condition includes the condition that the first recording sheet S has not been ejected. Therefore, the first recording sheet S is transported to the cutting unit 6 without being held at the switchback position. This allows the cutting of the first recording sheet S in the cutting unit 6 to start as quickly as possible.
[0172] Furthermore, the first condition is that the state is other than the second condition described above. Therefore, the second recording sheet S can be kept waiting at the switchback position until the continuation operation is performed. When the continuation operation is performed, the second recording sheet S, which will have an image recorded on it and be cut, can be transported from the switchback position to the cutting unit 6. As a result, the cutting of the second recording sheet S, which will have an image recorded on it and be cut, at the cutting unit 6 can be started as quickly as possible. In addition, if the quality of the output corresponding to the first recording sheet S is poor, the recording and cutting of images on the second and subsequent recording sheets S can be stopped. Therefore, the consumption of wasted ink and recording sheets S can be reduced.
[0173] Furthermore, the first and second conditions may be different from those described in variations 2-5.
[0174] <Variation 6> Furthermore, the switchback position may be a different position from that described in the above-described embodiment. For example, in modified example 6, as shown in Figure 21, the transition path 161 in the printer 160 has an upstream path 161A, a switchback path 161B, and a downstream path 161C.
[0175] The upstream path 161A branches off from the reversal transport path 54 at the branching section 54A. The upstream path 161A also extends backward from the branching section 54A. Furthermore, the upstream path 161A curves downward midway and then curves forward. In other words, the upstream path 161A is a path that extends backward, curves in a U shape, and then extends forward. An upstream path roller 162 is also provided for the upstream path 161A.
[0176] Furthermore, in the printer 160, the path member 166 is positioned below the paper cassette 5 and above the cutting section 6. Also, when viewed from above, the paper cassette 5 and the path member 166 overlap.
[0177] The switchback path 161B is formed between the paper cassette 5 and the path member 166 in the vertical direction. The lower surface of the paper cassette 5 is the upper wall surface of the switchback path 161B. The upper surface of the path member 166 is the lower wall surface of the switchback path 161B.
[0178] Therefore, the switchback path 161B is located below the paper cassette 5 and above the cutting section 6. The switchback path 161B extends forward from the front end opposite the branching section 54A of the upstream path 161A. Furthermore, the switchback path 161B extends at an angle with respect to the front-to-back direction, so that it rises as it extends forward. In other words, the switchback path 161B extends at an angle with respect to the horizontal plane so that the front is higher. A second switchback roller 163 is also provided with respect to the switchback path 161B.
[0179] Furthermore, when the paper cassette 5 is pulled forward from the housing 1A and removed from the housing 1A, the switchback path 161B and the second switchback roller 163 are exposed. In other words, the second switchback roller 163 and the switchback path 161B become visible from the opening into which the paper cassette 5 is installed. Also, the second switchback roller 163 and the switchback path 161B become accessible from the opening into which the paper cassette 5 is installed. In addition, any jammed recording paper S in the switchback path 161B becomes visible and accessible from the opening into which the paper cassette 5 is installed. A paper sensor 169 is located behind the second switchback roller 163.
[0180] The downstream path 161C is located behind the switchback path 161B and below the upstream path 161A. The downstream path 161C extends backward and downward from its position behind the switchback path 161B, and then curves downward. The downstream path 161C further curves downward and forward, extending to the upper surface of the support member 35. In other words, the downstream path 161C is a path that extends backward, curves in a U shape, and extends forward. A downstream path roller 164 is also provided on the downstream path 161C.
[0181] Furthermore, a guide member 165 is positioned between the upstream path 161A and the downstream path 161C and the switchback path 161B in the front-rear direction. The guide member 165 is configured to be movable between a downstream guide position shown by a solid line in Figure 21 and an upstream guide position shown by a dashed line in Figure 21. The downstream guide position is the position when guiding the recording paper S from the switchback path 161B to the downstream path 161C. The upstream guide position is the position when guiding the recording paper S from the upstream path 161A to the switchback path 161B. The guide member 165 is also biased from the upstream guide position towards the downstream guide position by a spring or the like (not shown).
[0182] In the modified example 6, the control unit 100 can perform normal single-sided recording, normal double-sided recording, cut single-sided recording, and cut double-sided recording by processing according to the flowcharts in Figures 7(a) to (d), similar to the embodiments described above.
[0183] In modification 6, the control unit 100 also performs the transport process in S303 and S405 according to the flowchart in Figure 11. However, in modification 6, in the first transport process in S502, the control unit 100 controls the roller drive device 107, etc., to transport the recording paper S to the switchback path 161B.
[0184] Specifically, the control unit 100 causes the first switchback roller 64 to transport the recording paper S until the rear end of the recording paper S is in front of the branching section 53A. The control unit 100 then moves the guide member 81 to the second position. The control unit 100 then causes the first switchback roller 64 to transport the recording paper S backward. As shown in Figure 22(a), the recording paper S is then transported from the paper discharge path 53 to the reversal transport path 54, and further transported from the reversal transport path 54 to the upstream path 161A.
[0185] The control unit 100 further drives the upstream path roller 162 and the second switchback roller 163 to transport the recording paper S to the switchback path 161B. Specifically, after the recording paper S is detected by the paper sensor 169, the control unit 100 transports the recording paper S until the recording paper S is no longer detected by the paper sensor 169.
[0186] In Modification 6, the position of the recording paper S when the paper sensor 169 does not detect the recording paper S corresponds to the "switchback position" and "second switchback position" of the present invention. Furthermore, the combination of the switchback path 161B and the second switchback roller 163 corresponds to the "switchback section" and "second switchback section" of the present invention.
[0187] When the recording paper S is transported to the switchback path 161B, the guide member 165 is pushed by the recording paper S and moves toward the upstream guide position against the biasing force of the spring. Therefore, the recording paper S is guided to the switchback path 161B by the guide member 165 located in the upstream guide position. When the transport of the recording paper S to the switchback path 161B is complete, the guide member 165 returns to the downstream guide position due to the biasing force of the spring.
[0188] In the second transport process in S506, the control unit 100 controls the roller drive unit 107 to transport the recording paper S to the cutting unit 6. Specifically, the control unit 100 rotates the second switchback roller 163 in the opposite direction to that used in the first transport process.
[0189] Then, as shown in Figure 22(b), the recording paper S is fed backward from the switchback path 161B. In other words, a switchback is performed for the recording paper S. Furthermore, the recording paper S is guided to the guide member 165 located at the downstream guide position. Therefore, the recording paper S is transported from the switchback path 161B to the downstream path 161C.
[0190] Furthermore, the control unit 100 drives the downstream path roller 67 and the cutting section roller 34 to transport the recording paper S through the downstream path 161C and the upper surface of the support member 35 to the cutting section 6.
[0191] Furthermore, in the embodiment described above, the first switchback position is the position where the recording paper S after the switchback is transported toward the reversal transport path 54. On the other hand, the second switchback position is the position where the recording paper S after the switchback is transported toward the cutting section 6 without being transported toward the reversal transport path 54. The second switchback position is located downstream of the first switchback position in the transition path 55. However, it is not limited to this. The second switchback position may be located upstream of the first switchback position in the transition path 55.
[0192] Furthermore, although the transport path 50 had two switchback positions in the above-described embodiment, it is not limited to this. The transport path of the transport unit may have only one switchback position. The recording paper S may then be kept waiting at this single switchback position.
[0193] Alternatively, the transport path of the transport unit may have three or more switchback positions. The recording paper S may then be kept waiting at one of these three or more switchback positions.
[0194] Furthermore, in a printer where the transport path of the transport unit has two or more switchback positions, the recording paper S may be kept waiting at any of the switchback positions.
[0195] Furthermore, although the recording paper S was placed in standby position at the switchback position in the above example, this is not the only option. The recording paper S may be placed in standby position other than the switchback position on the transport path of the transport unit. In a configuration in which the recording paper S is placed in standby position other than the switchback position on the transport path of the transport unit, the transport path of the transport unit does not necessarily have a switchback position.
[0196] Furthermore, in the above example, the standby position is a position where the recording paper S located in the standby position does not come into contact with another recording paper S being cut by the cutting unit 6. However, this is not limited to this. The standby position may also be a position where the recording paper S located in the standby position comes into contact with another recording paper S being cut by the cutting unit.
[0197] Furthermore, in the above example, the standby position is a position where the recording paper S located in the standby position does not come into contact with another recording paper S that is currently being recorded by the recording unit 2. However, this is not limited to this. The standby position may also be a position where the recording paper S located in the standby position comes into contact with another recording paper S that is currently being recorded by the recording unit 2.
[0198] Furthermore, although the sensor 33 was provided on the cutter carriage 32 in the above-described embodiment, this is not the only possible configuration. For example, the sensor 33 may be attached to the portion of the housing 1A where the cutting section 6 is located.
[0199] Furthermore, in the above-described embodiment, the sensor 33 detected a mark M recorded on the recording paper S along with the image P, but it is not limited to this. The sensor 33 may also detect the image P recorded on the recording paper S.
[0200] Furthermore, the sensor 33 is not even necessary. For example, if the variation in the position of the recording paper S when it is transported to the cutting unit 6 is sufficiently small, the cutting unit 6 can appropriately cut the image based on the image data of the image being recorded.
[0201] Furthermore, while the above examples involved printers capable of normal single-sided recording, normal double-sided recording, cut single-sided recording, and cut double-sided recording, they are not limited to these. A printer may not be capable of one or both of normal single-sided and normal double-sided recording. Similarly, a printer may not be capable of one of either cut single-sided or cut double-sided recording.
[0202] Furthermore, in the above examples, the recording unit was equipped with a so-called serial head that ejects ink from nozzles while moving together with the carriage, but it is not limited to this. For example, the recording unit may be equipped with a so-called line head that extends along the entire length of the recording paper S in the left-right direction.
[0203] Furthermore, in the above examples, the recording unit recorded an image by ejecting ink from a nozzle toward the recording paper, thereby adhering the ink as a recording agent to the recording paper. In other words, the recording unit was a so-called inkjet type. However, it is not limited to this. For example, the recording unit may record an image on the recording paper by adhering toner as a recording agent to the recording paper. In other words, the recording unit may be a so-called laser type. [Explanation of Symbols]
