Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a conventional printer, a so-called setup operation is performed before automatically cutting the recording medium with a cutter. Here, in the setup operation, it is confirmed that the recording medium is surely placed on the platen by scanning a predetermined sensor in the main scanning direction. Then, when the setup operation is completed, the recording medium is cut by the cutter. Here, an image may be continuously printed on the recording medium and then the recording medium may be cut for each image. In a conventional printer, every time the cutting of the recording medium is completed, it is necessary to move the recording medium to the cutting position and perform the setup operation. Therefore, the longer the number of cuttings is, the longer the cumulative waiting time of the setup operation becomes, which has been a burden on the user using the printer.

[0005] The present invention has been made in view of the above, and its object is to provide an inkjet printer that can cut recording media more quickly. [Means for solving the problem]

[0006] The inkjet printer according to the present invention comprises: a platen on which a recording medium is placed; an ink head configured to be movable in the main scanning direction and ejecting ink onto the recording medium placed on the platen to print an image; a carriage positioned above the platen and movable in the main scanning direction; a carriage movement mechanism having a drive source for moving the carriage in the main scanning direction; a cutter mounted on the carriage for cutting the recording medium in the main scanning direction; a cutter movement mechanism for moving the cutter vertically; a cutter pad provided on the platen, extending in the main scanning direction and against which the cutter is pressed; and a control device for controlling the carriage movement mechanism and the cutter movement mechanism. The control device comprises: a mode selection unit configured to select between an automatic cutting mode in which the recording medium is automatically cut by the cutter and a manual cutting mode in which the recording medium is manually cut by the cutter; and when the manual cutting mode is selected, the control unit controls the cutter to move downward and press the cutter against the cutter pad, and controls the carriage to be able to move in the main scanning direction independently of the ink head.

[0007] According to the inkjet printer of the present invention, when the manual cutting mode is selected by the mode selection unit, the first control unit of the control device controls the cutter movement mechanism to move the cutter downward and press the cutter against the cutter pad. This makes the recording medium placed on the platen ready to be cut by the cutter. The first control unit then controls the carriage so that it can move independently of the ink head in the main scanning direction. This allows the user to manually move the carriage carrying the cutter. In this way, in manual cutting mode, the carriage carrying the cutter pressed against the cutter pad can be moved manually, so the recording medium can be manually cut by the cutter without going through a setup operation. Furthermore, when cutting other parts of the recording medium, the recording medium can be manually moved and cut by the cutter without going through a setup operation. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide an inkjet printer that can perform cutting of recording media more quickly. [Brief explanation of the drawing]

[0010] Hereinafter, an inkjet printer (hereinafter simply referred to as "printer") according to an embodiment of the present invention will be described with reference to the drawings. Naturally, the embodiments described herein are not intended to particularly limit the present invention. Furthermore, the same reference numerals are used for components and parts that perform the same function, and redundant explanations are omitted or simplified as appropriate.

[0011] Figure 1 is a front view showing a printer 10 according to this embodiment. The printer 10 prints on a recording medium 5. The recording medium 5 is, for example, formed in a long length and used wound in a roll. The recording medium 5 may also be a sheet-like material cut to a predetermined length from the roll. The recording medium 5 is, for example, recording paper. However, the recording medium 5 is not limited to recording paper. In addition to paper such as plain paper and inkjet printing paper, the recording medium 5 may be made from resin materials such as polyvinyl chloride (PVC) or polyester, or from metal plates made of aluminum or iron, glass plates, wooden boards, and corrugated cardboard.

[0012] In the following description, left, right, up, and down refer to the left, right, up, and down directions as viewed from the perspective of an operator facing the front of the printer 10. Furthermore, when the operator is facing the front of the printer 10, the direction from the rear of the printer 10 towards the operator is defined as the front, and the direction from the operator towards the rear of the printer 10 is defined as the rear. The symbols F, Rr, L, R, U, and D in the drawings represent front, rear, left, right, up, and down, respectively. The first carriage 28 and the second carriage 38, described later, are provided to be movable to the left and right. When the rear of the printer 10 is referred to as the upstream side and the front of the printer 10 as the downstream side, the recording medium 5 is transported from the upstream side to the downstream side and from the downstream side to the upstream side. In this embodiment, the movement direction of the first carriage 28 and the second carriage 38 is called the main scanning direction Y, and the transport direction of the recording medium 5 is called the sub-scanning direction X. Here, the main scanning direction Y corresponds to the left-right direction, and the sub-scanning direction X corresponds to the front-back direction. The main scanning direction Y and the sub-scanning direction X are orthogonal. Furthermore, the transport direction of the recording medium 5 (i.e., the sub-scanning direction X) from upstream to downstream is defined as the forward direction X1, and the direction from downstream to upstream is defined as the return direction X2. However, the main scanning direction Y and the sub-scanning direction X are not particularly limited and can be set appropriately according to the configuration of the printer 10, etc.

[0013] As shown in Figure 1, the printer 10 comprises a base member 10a extending in the main scanning direction Y, legs 11, an operation panel 12, a platen 16 on which the recording medium 5 is placed, a casing 10b attached to the base member 10a, an ink head unit 20, a cutter unit 30, a carriage movement mechanism 40, a media movement mechanism 55, a supply device 70, a winding device 90, and a control device 100. The legs 11 support the base member 10a and are provided on the lower surface of the base member 10a. The operation panel 12 is provided, for example, on the front right side of the casing 10b. However, the position of the operation panel 12 is not particularly limited. The operation panel 12 is used, for example, by an operator to perform operations related to printing and cutting the recording medium. Although not shown in the figure, the operation panel 12 is equipped with a display unit that shows information related to printing, such as resolution and ink density, as well as the status of the printer 10 during printing and the cutting mode, and an input unit for inputting information related to printing and cutting.

[0014] The platen 16 supports the recording medium 5 when printing onto it. The recording medium 5 is placed on the platen 16. The platen 16 has a mounting surface 16A (see Figure 2) on which the recording medium 5 is placed. The recording medium 5 is placed on the mounting surface 16A of the platen 16 before printing onto the recording medium 5. Printing of the print image onto the recording medium 5 and cutting of the recording medium 5 are performed on the platen 16. As shown in Figure 1, the platen 16 extends in the main scanning direction Y. As shown in Figure 2, the platen 16 is supported by the main body case 10c of the base member 10a. The main body case 10c is formed in a box shape with an open top. The internal space 17 is partitioned by the platen 16 and the main body case 10c.

[0015] As shown in FIG. 2, the platen 16 includes a plurality of suction holes 16H formed to penetrate in the vertical direction. The suction holes 16H communicate with the internal space 17. The suction holes 16H include downstream suction holes 16HF located forward (i.e., on the downstream side in the sub-scanning direction X) of an ink head 24 described later, and upstream suction holes 16HR located rearward (i.e., on the upstream side in the sub-scanning direction X) of the ink head 24. As shown in FIG. 4, the downstream suction holes 16HF and the upstream suction holes 16HR are arranged in the main scanning direction Y respectively.

[0016] As shown in FIG. 2, the printer 10 includes a fan 18. The fan 18 sucks air into the internal space 17. As shown by an arrow FL in FIG. 2, the fan 18 is configured to suck air into the internal space 17 through the suction holes 16H. Thereby, the recording medium 5 placed on the platen 16 is attracted (adsorbed) to the placement surface 16A of the platen 16, and the floating of the recording medium 5 is suppressed. The fan 18 is controlled by a control device 100 (see FIG. 1).

[0017] As shown in FIG. 4, the printer 10 includes a cutter pad 19 provided on the platen 16. The cutter pad 19 extends in the main scanning direction Y. The cutter pad 19 is embedded in the platen 16. The cutter pad 19 is provided between the upstream suction holes 16HR and the downstream suction holes 16HF with respect to the sub-scanning direction X. The cutter pad 19 is a member against which a first cutter 27, a second cutter 37, and a sheet cutter 33 described later are pressed. The cutter pad 19 is a member that suppresses damage to the first cutter 27 and the like. The cutter pad 19 is formed of, for example, rubber.

[0018] As shown in FIG. 1, the printer 10 includes a central wall 14 extending in the main scanning direction Y and the vertical direction. The central wall 14 is supported by the base member 10a. The central wall 14 is disposed above the platen 16. A gap through which the recording medium 5 can pass is formed between the central wall 14 and the platen 16. The printer 10 includes guide rails 15. The guide rails 15 extend in the main scanning direction Y. The guide rails 15 are provided on the central wall 14. The guide rails 15 are disposed above the platen 16.

[0019] As shown in FIG. 3A, the ink head unit 20 includes a first carriage 28, a plurality of ink heads 24, and a first cutter 27. The first carriage 28 engages with the guide rail 15. The first carriage 28 is configured to be movable in the main scanning direction Y along the guide rail 15. As will be described later, the first carriage 28 moves in the main scanning direction Y together with a second carriage 38 of a cutter unit 30 to be described later. The first carriage 28 is mounted with the ink heads 24 and the first cutter 27. The ink heads 24 and the first cutter 27 are configured to be movable in the main scanning direction Y as the first carriage 28 moves. The ink heads 24 discharge ink onto the recording medium 5 placed on the platen 16 to print an image. Here, five ink heads 24 are mounted on the first carriage 28. However, the number of ink heads 24 is not limited to five. The first carriage 28 is an example of an ink head carriage.

[0020] As shown in Figure 3A, the first cutter 27 is configured to cut the recording medium 5 placed on the platen 16 in the sub-scanning direction X. In this embodiment, the first cutter 27 cuts the recording medium 5 only in the sub-scanning direction X. The first cutter 27 is configured to be movable in the vertical direction (i.e., able to approach and move away from the recording medium 5) by a first cutter movement mechanism 26 (see Figure 6) controlled by the control device 100. The first cutter 27 is configured to be movable in the vertical direction by the first cutter movement mechanism 26 when positioned on one side (e.g., the right side) of the main scanning direction of the recording medium 5. As shown in Figure 3B, when the first cutter 27 cuts the recording medium 5 in the sub-scanning direction X, it is pressed against a cutter pad 19 placed on the platen 16. The first cutter 27 comes into contact with the recording medium 5. The first cutter 27 is, for example, a roller cutter (rotary cutter).

[0021] As shown in Figure 3A, the cutter unit 30 comprises a second carriage 38, a sheet cutter 33, and a second cutter 37. The second carriage 38 is engaged with the guide rail 15. The second carriage 38 is configured to be movable along the guide rail 15 in the main scanning direction Y. The second carriage 38 is detachably mounted on the first carriage 28. As will be described later, the second carriage 38 moves in the main scanning direction Y together with the first carriage 28 of the inkhead unit 20, or independently (i.e., independently of the first carriage 28). The sheet cutter 33 and the second cutter 37 are mounted on the second carriage 38. The sheet cutter 33 and the second cutter 37 are configured to be movable in the main scanning direction Y as the second carriage 38 moves. The second carriage 38 is an example of a carriage.

[0022] As shown in Figure 3A, the sheet cutter 33 is configured to cut the recording medium 5 placed on the platen 16 in the main scanning direction Y. The sheet cutter 33 is an example of a cutter. In this embodiment, the sheet cutter 33 cuts the recording medium 5 only in the main scanning direction Y. The sheet cutter 33 is configured to be movable in the vertical direction by a sheet cutter moving mechanism 34 (see Figure 6) controlled by the control device 100. The sheet cutter moving mechanism 34 is an example of a cutter moving mechanism. As shown in Figure 3C, when the sheet cutter 33 cuts the recording medium 5 in the main scanning direction Y, it is pressed against a cutter pad 19 placed on the platen 16. As shown in Figure 4, the sheet cutter 33 is located downstream (in this case forward) of the grit roller 57 and grit roller 57 (see Figure 1), which will be described later, in the sub-scanning direction X.

[0023] As shown in Figure 3A, the second cutter 37 is configured to cut the recording medium 5 placed on the platen 16 in the sub-scanning direction X. The second cutter 37 is an example of a second cutter. In this embodiment, the second cutter 37 cuts the recording medium 5 only in the sub-scanning direction X. The second cutter 37 has the same configuration as the first cutter 27. The second cutter 37 is configured to be movable vertically by a second cutter movement mechanism 36 (see Figure 6) controlled by the control device 100. The second cutter 37 is configured to be movable vertically by the second cutter movement mechanism 36 when it is positioned, for example, on the other side (e.g., the left side) of the main scanning direction of the recording medium 5. As shown in Figure 3B, when the second cutter 37 cuts the recording medium 5 in the sub-scanning direction X, it is pressed against a cutter pad 19 placed on the platen 16. The second cutter 37 comes into contact with the recording medium 5. The second cutter 37 is, for example, a roller cutter (rotary cutter).

[0024] The carriage movement mechanism 40 is a mechanism that moves the first carriage 28 of the ink head unit 20 and the second carriage 38 of the cutter unit 30 relative to the recording medium 5 placed on the platen 16 in the main scanning direction Y. The carriage movement mechanism 40 moves the first carriage 28 and the second carriage 38 in the main scanning direction Y. The configuration of the carriage movement mechanism 40 is not particularly limited. As shown in Figure 1, the carriage movement mechanism 40 includes a first pulley 41, a second pulley 42, an endless belt 43, and a carriage motor 44. The first pulley 41 is provided on the left end side of the guide rail 15. The second pulley 42 is provided on the right end side of the guide rail 15. The belt 43 is wrapped around the first pulley 41. The belt 43 is fixed to the upper rear of the second carriage 38 (see also Figure 3A). The carriage motor 44 is connected to the second pulley 42. However, the carriage motor 44 may also be connected to the first pulley 41. Here, the carriage motor 44 is driven, causing the second pulley 42 to rotate, and the belt 43 travels between the first pulley 41 and the second pulley 42. As a result, the second carriage 38 moves in the main scanning direction Y. That is, the carriage motor 44 moves the second carriage 38 in the main scanning direction Y. As will be described later, the first carriage 28 moves in the main scanning direction Y along with the movement of the second carriage 38. The carriage motor 44 indirectly moves the first carriage 28 in the main scanning direction Y via the second carriage 38. The carriage motor 44 is controlled by the control device 100. The control device 100 controls the supply and de-supply of power to the carriage motor 44. The carriage motor 44 is an example of a drive source.

[0025] As shown in Figure 3A, a first connecting member 29, which is made of a magnet, is provided on the left side of the first carriage 28. A second connecting member 39, which is made of an electromagnet, is fixed to the right side of the second carriage 38. The ON and OFF of the power supply to the second connecting member 39 is controlled by the control device 100. The first connecting member 29 is detachably connected to the second connecting member 39. In this embodiment, the first connecting member 29 and the second connecting member 39 utilize magnetic force. However, the first connecting member 29 and the second connecting member 39 are not limited to those that utilize magnetic force, and may have other configurations such as engaging members.

[0026] As shown in Figure 3A, when the ink head 24 prints a predetermined image onto the recording medium 5, the second carriage 38 and the first carriage 28 are connected. As a result, the ink head unit 20 becomes movable in the main scanning direction Y together with the cutter unit 30. That is, the carriage motor 44 (see Figure 1) drives the first carriage 28 and the second carriage 38 to move in the main scanning direction Y. On the other hand, when the sheet cutter 33 cuts the recording medium 5 in the main scanning direction Y, as shown in Figure 4, with the ink head unit 20 in the home position HP, the power supply to the second connecting member 39 is stopped, and the connection between the second connecting member 39 and the first connecting member 29 is released. As a result, with the ink head unit 20 waiting in the home position HP, only the cutter unit 30 becomes movable in the main scanning direction Y. Furthermore, when the recording medium 5 is cut in the sub-scanning direction X by the first cutter 27 and the second cutter 37, as shown in Figure 3B, the ink head unit 20 is positioned in a predetermined position (for example, a position where the first cutter 27 is located to the left of the first side pinch roller 60R described later), and the power supply to the second connecting member 39 is stopped to release the connection between the second connecting member 39 and the first connecting member 29. Then, only the cutter unit 30 is moved in the main scanning direction Y to position the cutter unit 30 in a predetermined position (for example, a position where the second cutter 37 is located to the right of the second side pinch roller 60L described later). This makes it possible to cut the portion of the recording medium 5 that is to the left of the first side pinch roller 60R and to the right of the second side pinch roller 60L. Here, the area to the left of the first side pinch roller 60R and to the right of the second side pinch roller 60L is the normal printing area, and an image is printed there. Therefore, the first cutter 27 and the second cutter 37 may cut the image printed on the recording medium 5.

[0027] The media movement mechanism 55 moves the recording medium 5, which is placed on the platen 16, relative to the first carriage 28 and the second carriage 38 in the sub-scanning direction X. The media movement mechanism 55 moves the recording medium 5, which is placed on the platen 16, in the sub-scanning direction X (i.e., the forward direction X1 and the return direction X2). When an image is printed on the recording medium 5, the media movement mechanism 55 moves the recording medium 5 in the forward direction X1. When the recording medium 5 is cut in the sub-scanning direction X by the first cutter 27 and the second cutter 37, the media movement mechanism 55 moves the recording medium 5 in the forward direction X1 or the return direction X2. By moving the recording medium 5 in the sub-scanning direction X with the first cutter 27 and the second cutter 37 in contact with the recording medium 5, the recording medium 5 is configured so that one end (here, the right end) and the other end (here, the left end) in the main scanning direction Y of the recording medium 5, which has an image printed on it by the ink head 24, are cut simultaneously. As shown in Figure 1, the media transfer mechanism 55 includes a grid roller 57, a feed motor 58 (see Figure 6), a pinch roller 60, a holding shaft 64, and a loading lever 65.

[0028] As shown in Figure 1, the grid roller 57 is provided on the platen 16. The grid roller 57 is embedded in the platen 16 such that its upper part is exposed to the outside. The grid roller 57 is arranged in parallel in the main scanning direction Y. As shown in Figure 4, the grid roller 57 is positioned behind the suction hole 16H (i.e., upstream in the sub-scanning direction X). The grid roller 57 is positioned below the pinch roller 60. The grid roller 57 holds the recording medium 5 between itself and the pinch roller 60. A feed motor 58 (see Figure 6) is connected to the grid roller 57. The feed motor 58 is controlled by the control device 100. That is, the grid roller 57 is controlled by the control device 100. When the feed motor 58 is driven and the grid roller 57 rotates with the recording medium 5 sandwiched between the grid roller 57 and the pinch roller 60, the recording medium 5 is transported in the sub-scanning direction X.

[0029] As shown in Figure 1, the pinch roller 60 is positioned above the platen 16. The pinch roller 60 is positioned below the guide rail 15. The pinch roller 60 is positioned opposite the grid roller 57. The pinch roller 60 presses down on the recording medium 5 placed on the platen 16. The pinch roller 60 includes a first side pinch roller 60R that presses down on the right end of the recording medium 5 and a second side pinch roller 60L that presses down on the left end of the recording medium 5. The pinch roller 60 can be repositioned along the holding shaft 64 in the main scanning direction Y.

[0030] As shown in Figure 1, the holding shaft 64 extends in the main scanning direction Y. The holding shaft 64 holds the pinch roller 60. By rotating the holding shaft 64 around its axis, the pinch roller 60 can be brought closer to or further away from the grid roller 57. The holding shaft 64 is rotatably supported on the base member 10a.

[0031] As shown in Figure 1, the loading lever 65 is provided on the base member 10a. The loading lever 65 is provided so as to protrude from the platen 16. The loading lever 65 is connected to the holding shaft 64. The loading lever 65 can move the pinch roller 60 vertically. Pushing up the loading lever 65 rotates the holding shaft 64 and moves the pinch roller 60 upward (i.e., away from the grit roller 57). Pushing down the loading lever 65 rotates the holding shaft 64 and moves the pinch roller 60 downward (i.e., closer to the grit roller 57). The loading lever 65 is operated by the user. When the pinch roller 60 moves upward or downward due to the operation of the loading lever 65, position information of the pinch roller 60 is transmitted to the control device 100 by a sensor (not shown).

[0032] As shown in Figure 2, the supply device 70 is positioned upstream (rear in this case) of the platen in the sub-scanning direction X. The supply device 70 rotatably supports the supply shaft 71 around which the recording medium 5 is wound. The supply device 70 includes a main body 70A, a support member 72 that supports the supply shaft 71, a drive motor 75 (see Figure 5) that rotates the supply shaft 71, a clutch 78 (see Figure 5) interposed between the drive motor 75 and the supply shaft 71, and a slip clutch 82 (see Figure 5) interposed between the drive motor 75 and the clutch 78. Note that the drive motor 75, clutch 78, and slip clutch 82 are not shown in Figures 1 and 2.

[0033] As shown in Figure 1, the main body 70A is attached to the leg portion 11. The main body 70A has a left support wall 70L provided on the left leg portion 11 and extending rearward, a right support wall 70R provided on the right leg portion 11 and extending rearward, and a pair of guide pipes 70P and 70Q (see Figure 2) that extend in the main scanning direction Y and are supported by the left support wall 70L and the right support wall 70R.

[0034] As shown in Figure 2, the supply shaft 71 is positioned below the platen 16. The supply shaft 71 is positioned behind the platen 16. As shown in Figure 1, the supply shaft 71 is formed in the shape of a cylindrical tube extending in the main scanning direction Y. The supply shaft 71 is detachably attached to the support member 72. The recording medium 5 wound around the supply shaft 71 is unwound from the supply shaft 71. The supply shaft 71 winds up the recording medium 5 moving in the return direction X2.

[0035] As shown in Figure 2, the support member 72 rotatably supports the supply shaft 71. The support member 72 rotatably supports the supply shaft 71 in a first direction S1 (counterclockwise when viewed from right to left), which is the direction of rotation of the supply shaft 71 when the recording medium 5 unwound from the supply shaft 71 moves in the forward direction X1, and in a second direction S2 (clockwise when viewed from right to left), which is the opposite direction of the first direction S1. The support member 72 is provided to be movable in the main scanning direction Y along the guide pipes 70P and 70Q. The support member 72 includes a right main body portion 72R (see also Figure 5) that engages with the guide pipes 70P and 70Q, a left main body portion 72L that engages with the guide pipes 70P and 70Q and is located to the left of the right main body portion 72R, a right support portion 73R (see also Figure 5) that is rotatably mounted on the right main body portion 72R and supports the right end of the supply shaft 71, and a left support portion 73L that is rotatably mounted on the left main body portion 72L and supports the left end of the supply shaft 71. Since the right main body portion 72R and the left main body portion 72L have the same configuration, the description of the right main body portion 72R will be explained below, and the description of the left main body portion 72L will be omitted. Similarly, since the right support portion 73R and the left support portion 73L have the same configuration, the description of the right support portion 73R will be explained below, and the description of the left support portion 73L will be omitted.

[0036] As shown in Figure 5, the right main body 72R extends in the sub-scanning direction X and in the vertical direction. The right main body 72R is formed in a roughly triangular shape when viewed from the main scanning direction Y. The right main body 72R has a tubular portion 72X and an engaging recess 72Y. The tubular portion 72X is provided at the rear vertex of the two lower vertices of the roughly triangular shape. The tubular portion 72X is configured as a circular tube extending in the main scanning direction Y. A guide pipe 70Q (see Figure 2) is inserted through the tubular portion 72X. The engaging recess 72Y is provided at the front vertex of the two lower vertices of the roughly triangular shape. The engaging recess 72Y has a roughly C-shape with the front side open when viewed from the main scanning direction Y. The engaging recess 72Y is a recess that is recessed toward the rear. A guide pipe 70P (see Figure 2) is inserted through the engaging recess 72Y.

[0037] As shown in Figure 5, the right support portion 73R is formed in a substantially cylindrical shape. The right support portion 73R is located near the upper vertex of the substantially triangular shape of the right main body portion 72R. The right support portion 73R extends to the left from the right main body portion 72R. The supply shaft 71 is mounted on the right support portion 73R. That is, the right support portion 73R is inserted into the supply shaft 71.

[0038] As shown in Figure 5, the supply device 70 includes a drive motor 75, a clutch 78, a slip clutch 82, and a support case 74 that supports them. The support case 74 is provided on the right main body portion 72R of the support member 72. The support case 74 is provided on the side opposite to the side to which the right support portion 73R is attached (the left side in this case) (the right side in this case).

[0039] As shown in Figure 5, the drive motor 75 is supported by the support case 74. The drive motor 75 is located below the clutch 78. The drive motor 75 is located to the left of the slip clutch 82. The drive motor 75 rotates the supply shaft 71 in the second direction S2 (see Figure 2) in which the recording medium 5 is wound onto the supply shaft 71. The drive motor 75 is controlled by the control device 100.

[0040] As shown in Figure 5, the slip clutch 82 is connected to the drive motor 75. The slip clutch 82 is equipped with a first gear 82A. The slip clutch 82 limits the rotational force applied to the supply shaft 71 by the drive of the drive motor 75. That is, when a torque reaction force (load from the recording medium 5) greater than a predetermined value is applied to the slip clutch 82, the sliding mechanism within the slip clutch 82 prevents the rotational force of the drive motor 75 from being applied to the supply shaft 71. When a torque reaction force less than a predetermined value is applied to the slip clutch 82, the clutch engages and the rotational force of the drive motor 75 is applied to the supply shaft 71.

[0041] As shown in Figure 5, the supply device 70 includes a first shaft 79L connected to the left end of the clutch 78 and connected to the right support portion 73R, a second shaft 79R connected to the right end of the clutch 78, and a second gear 78A provided on the second shaft 79R that meshes with the first gear 82A of the slip clutch 82. The clutch 78 is disconnected when the supply shaft 71 rotates in a first direction S1 (see Figure 2), which is the paper feeding direction in which the recording medium 5 is unwound from the supply shaft 71, and is engaged when the supply shaft 71 rotates in a second direction S2 (see Figure 2), which is the direction in which the recording medium 5 is wound onto the supply shaft 71. That is, when the supply shaft 71 rotates in the first direction S1, the first shaft 79L rotates together with the supply shaft 71, but the second shaft 79R does not rotate together with the supply shaft 71. On the other hand, when the supply shaft 71 rotates in the second direction S2, the clutch 78 connects the first shaft 79L and the second shaft 79R, so the first shaft 79L and the second shaft 79R rotate together with the supply shaft 71. The clutch 78 in this embodiment is a one-way clutch.

[0042] As shown in Figure 5, the supply device 70 is equipped with a rotary damper 85. The rotary damper 85 is positioned to rotate together with the supply shaft 71. That is, the rotary damper 85 rotates together with the right support portion 73R. The rotary damper 85 is located on the right main body portion 72R. The rotary damper 85 resists the rotation of the supply shaft 71 when the supply shaft 71 rotates in the first direction S1 (see Figure 2).

[0043] As shown in Figure 2, the winding device 90 is positioned downstream (in this case forward) of the platen in the sub-scanning direction X. The winding device 90 rotatably supports a winding shaft 91 that winds up the recording medium 5 moving in the forward direction X1. As shown in Figure 1, the winding device 90 includes a main body 90A, a support member 92 that supports the winding shaft 91, a motor 93 that rotates the winding shaft 91, a tension bar 94 that applies tension to the recording medium 5, and a support arm 95 that supports the tension bar 94. The main body 90A is attached to the leg portion 11. The main body 90A has a bottom wall 90B extending in the main scanning direction Y, a right side wall 90R located at the right end of the bottom wall 90B, and a left side wall 90L located at the left end of the bottom wall 90B.

[0044] As shown in Figure 2, the winding shaft 91 is positioned below the platen 16. The winding shaft 91 is positioned in front of the platen 16. As shown in Figure 1, the winding shaft 91 is formed in a cylindrical shape extending in the main scanning direction Y. The winding shaft 91 is detachably attached to the support member 92. The winding shaft 91 winds the recording medium 5 into a roll. The winding shaft 91 winds the recording medium 5 after printing. The support member 92 rotatably supports the winding shaft 91. The support member 92 supports the left end and the right end of the winding shaft 91, respectively. The support member 92 is provided on the bottom wall 90B of the main body 90A. The support member 92 is located between the right side wall 90R and the left side wall 90L. The motor 93 is connected to the winding shaft 91. The motor 93 rotates the winding shaft 91 in the direction of arrow M in Figure 2. The motor 93 is mounted on the support member 92.

[0045] As shown in Figure 2, the tension bar 94 is a member that applies tension to the portion of the recording medium 5 located between the platen 16 and the winding shaft 91. More specifically, the tension bar 94 applies tension to the recording medium 5 by using its own weight to push the recording medium 5 diagonally forward and downward. The tension bar 94 is formed in a cylindrical or cylindrical shape that extends in the main scanning direction Y. The tension bar 94 is positioned parallel to the winding shaft 91. The tension bar 94 is positioned below the platen 16. The tension bar 94 is positioned in front of the winding shaft 91. As shown in Figure 1, the tension bar 94 is supported by a support arm 95. The support arm 95 is pivotably mounted on the left wall 90L and the right wall 90R, respectively.

[0046] As shown in Figure 6, the overall operation of the printer 10 is controlled by the control device 100. The configuration of the control device 100 is not particularly limited. The control device 100 is, for example, a microcomputer. The hardware configuration of the microcomputer is not particularly limited, but for example, it includes an interface (I / F) for receiving print data from external devices such as a host computer, a central processing unit (CPU) for executing instructions of the control program, a ROM for storing the program executed by the CPU, RAM used as a working area for expanding the program, and a storage device such as memory for storing the program and various data. As shown in Figure 1, the control device 100 is located inside the casing 10b. However, the control device 100 does not have to be located inside the casing 10b. For example, the control device 100 may be a computer installed outside the casing 10b. In this case, the control device 100 is connected to the printer 10 in a communicative manner via wired or wireless connection.

[0047] As shown in Figure 6, the control device 100 is communicatively connected to the operation panel 12, fan 18, ink head 24, first cutter moving mechanism 26, sheet cutter moving mechanism 34, second cutter moving mechanism 36, carriage motor 44, second connecting member 39, feed motor 58, drive motor 75, and motor 93. The control device 100 controls the fan 18, ink head 24, first cutter moving mechanism 26, sheet cutter moving mechanism 34, second cutter moving mechanism 36, carriage motor 44, second connecting member 39, feed motor 58, drive motor 75, and motor 93.

[0048] As shown in Figure 6, the control device 100 includes a print control unit 102, a cut control unit 104, a movement control unit 106, a mode selection unit 108, a first control unit 110, and a second control unit 112. The functions of each part of the control device 100 are realized by a program. This program is written, for example, to a ROM mounted on a circuit board inside the printer 10 via a LAN from a PC, or to an FPGA mounted on a circuit board inside the printer 10 using a dedicated writing jig from a PC. This program is also downloaded to a PC via the internet. Furthermore, the functions of each part of the control device 100 may also be realized by a processor and / or circuits. The specific functions of these parts will be described later.

[0049] The print control unit 102 is the part that ejects ink from the ink head 24 to print an image onto the recording medium 5. The print control unit 102 controls the carriage motor 44 of the carriage movement mechanism 40 and the ink head 24. The print control unit 102 is configured to eject ink from the ink head 24 onto the recording medium 5 when the recording medium 5 moves in the forward direction X1 by the media movement mechanism 55.

[0050] The cutting control unit 104 is the part that cuts the recording medium 5 in the sub-scanning direction X using the first cutter 27 and the second cutter 37. The cutting control unit 104 is the part that cuts the recording medium 5 in the main scanning direction Y using the sheet cutter 33. The cutting control unit 104 controls the first cutter moving mechanism 26, the sheet cutter moving mechanism 34, the second cutter moving mechanism 36, the carriage motor 44 of the carriage moving mechanism 40, and the second connecting member 39. When cutting the recording medium 5 in the sub-scanning direction X, the cutting control unit 104 controls the carriage motor 44 and the second connecting member 39 to position the first carriage 28 and the second carriage 38 in predetermined positions, and then controls the first cutter moving mechanism 26 and the second cutter moving mechanism 36 to move the first cutter 27 and the second cutter 37 downwards and press them against the cutter pad 19. The cutting control unit 104 positions the first carriage 28 and the second carriage 38 in predetermined positions based on the width information of the recording medium 5 stored in the control device 100. Furthermore, when cutting the recording medium 5 in the sub-scanning direction Y, the cutting control unit 104 controls the sheet cutter moving mechanism 34 to move the sheet cutter 33 downward and press it against the cutter pad 19, and then controls the carriage motor 44 to move the second carriage 38, on which the sheet cutter 33 is mounted, in the main scanning direction Y. The cutting control unit 104 is configured to cut the recording medium 5 when the recording medium 5 moves in the forward direction X1 and the return direction X2 by the media moving mechanism 55.

[0051] The movement control unit 106 is the part that moves the recording medium 5 in the sub-scanning direction X (i.e., the forward direction X1 and the return direction X2). The movement control unit 106 controls the feed motor 58 of the media movement mechanism 55. When the ink head 24 prints an image on the recording medium 5, the movement control unit 106 controls the feed motor 58 to move the recording medium 5 in the forward direction X1 after the first carriage 28 has made one round trip in the main scanning direction Y. When the first cutter 27 and the second cutter 37 cut the recording medium 5 in the sub-scanning direction X, the movement control unit 106 controls the feed motor 58 to move the recording medium 5 in the forward direction X1 or the return direction X2. When the sheet cutter 33 cuts the recording medium 5 in the main scanning direction Y, the movement control unit 106 controls the feed motor 58 to move the recording medium 5 in the forward direction X1 or the return direction X2. Furthermore, when the sheet cutter 33 cuts the recording medium 5 in the main scanning direction Y, the movement control unit 106 may control the feed motor 58 to move the recording medium 5 in the return direction X2, wind up the recording medium 5 with the supply shaft 71, and then move the recording medium 5 in the forward direction X1. The movement control unit 106 is also the part that winds up the recording medium 5 (for example, a recording medium 5 with an image printed on it) with the winding shaft 91. The movement control unit 106 controls the motor 93 of the winding device 90. The movement control unit 106 winds up the recording medium 5 moving in the forward direction X1 with the winding shaft 91. Furthermore, the movement control unit 106 is also the part that winds up the recording medium 5 (for example, a recording medium 5 with an image printed on it) with the supply shaft 71. The movement control unit 106 controls the drive motor 75 of the supply device 70. The movement control unit 106 winds up the recording medium 5 moving in the return direction X2 with the supply shaft 71.

[0052] The mode selection unit 108 is configured to allow selection between an automatic cutting mode, in which the recording medium 5 is automatically cut by the sheet cutter 33, and a manual cutting mode, in which the recording medium 5 is manually cut by the sheet cutter 33. The user can select either the automatic cutting mode or the manual cutting mode by operating the operation panel 12. When the automatic cutting mode is selected, the recording medium 5 is automatically cut in the main scanning direction Y by the cutting control unit 104 described above.

[0053] When the manual cutting mode is selected by the mode selection unit 108, the first control unit 110 moves the sheet cutter 33 downward to press it against the cutter pad 19, and controls the second carriage 38 so that it can move independently of the ink head 24 in the main scanning direction Y. The first control unit 110 controls the second carriage 38 so that it can move independently of the ink head 24 in the main scanning direction Y by stopping the power supply to the carriage motor 44. The first control unit 110 controls the second carriage 38 so that it can move independently of the ink head 24 in the main scanning direction Y by releasing the connection between the second carriage 38 and the first carriage 28. The first control unit 110 controls the carriage motor 44 of the sheet cutter moving mechanism 34 and the carriage moving mechanism 40. The first control unit 110 controls the ON and OFF of the power supply to the second connecting member 39.

[0054] The second control unit 112 drives the fan 18 when the pinch roller 60 moves downward by the loading lever 65 while the manual cutting mode is selected by the mode selection unit 108. The second control unit 112 stops the fan 18 when the pinch roller 60 moves upward by the loading lever 65 while the manual cutting mode is selected. The second control unit 112 controls the fan 18.

[0055] Next, we will explain how to cut the recording medium 5 in manual cutting mode. Figure 7 is a flowchart showing the procedure for cutting the recording medium 5 in the main scanning direction Y in manual cutting mode. Here, we will explain as an example the case in which the recording medium 5 with the printed image is wound up by the supply shaft 71, and then cut in the main scanning direction Y while moving the recording medium 5 in the forward direction X1.

[0056] First, in step S10, the user operates the control panel 12 to select the manual cutting mode. As a result, the mode selection unit 108 selects the manual cutting mode.

[0057] In step S20, the first control unit 110 controls the sheet cutter moving mechanism 34 to move the sheet cutter 33 downward and press the sheet cutter 33 against the cutter pad 19. The sheet cutter 33 is pressed against the cutter pad 19 with a load capable of cutting the recording medium 5. Note that when the sheet cutter 33 is pressed against the cutter pad 19, the recording medium 5 is not normally located below the sheet cutter 33.

[0058] In step S30, the first control unit 110 stops supplying power to the carriage motor 44. This makes the second carriage 38, on which the sheet cutter 33 is mounted, movable by the user in the main scanning direction Y. In this embodiment, when the second carriage 38 is moved manually, the first control unit 110 stops supplying power to the second connecting member 39, thereby releasing the connection between the first carriage 28 and the second carriage 38.

[0059] In step S40, the user pushes up the loading lever 65. This causes the pinch roller 60 to move upward and separate from the recording medium 5. In other words, the state in which the recording medium 5 was held between the pinch roller 60 and the grid roller 57 is released.

[0060] In step S50, the user manually pulls out the recording medium 5 in the forward direction X1 to adjust the position to be cut by the sheet cutter 33.

[0061] In step S60, the user pushes down the loading lever 65. This causes the pinch roller 60 to move downward, pressing down on the recording medium 5 from above. In other words, the recording medium 5 is held between the pinch roller 60 and the grid roller 57.

[0062] In step S70, the second control unit 112 drives the fan 18 because the pinch roller 60 has moved downward by the loading lever 65 while the manual cutting mode is selected. As a result, the recording medium 5 placed on the platen 16 is pulled towards the mounting surface 16A of the platen 16, and the lifting of the recording medium 5 is suppressed.

[0063] In step S80, the user manually moves the second carriage 38, on which the sheet cutter 33 is mounted, in the main scanning direction Y, thereby cutting the recording medium 5 in the main scanning direction Y. Here, since the sheet cutter 33 is located in front of the pinch roller 60 and the grit roller 57, if the recording medium 5 is cut over its entire width, there is a risk that the portion of the recording medium 5 located in front of the pinch roller 60 (the recording medium 5 after cutting) will slide off the platen 16. However, since the recording medium 5 after cutting is pulled towards the mounting surface 16A of the platen 16 by the fan 18, even if the recording medium 5 is cut over its entire width, the sliding off the recording medium 5 after cutting is suppressed.

[0064] In step S90, the user pushes up the loading lever 65. This causes the pinch roller 60 to move upward and separate from the recording medium 5. In other words, the state in which the recording medium 5 was held between the pinch roller 60 and the grid roller 57 is released. Note that the second control unit 112 stops the fan 18 when the pinch roller 60 moves upward by the loading lever 65 while the manual cutting mode is selected, so the user removes the cut recording medium 5 from the platen 16 before pushing up the loading lever 65.

[0065] In step S100, the user determines whether the cutting of the recording medium 5 is complete. If the cutting of the recording medium 5 is not complete, the process returns to step S50. That is, the user manually pulls out the recording medium 5 in the forward direction X1 to adjust the position to be cut by the sheet cutter 33. On the other hand, if the cutting of the recording medium 5 is complete, the process proceeds to step S110.

[0066] In step S110, the user operates the control panel 12 to exit manual cutting mode.

[0067] As described above, according to the printer 10 of this embodiment, when the manual cutting mode is selected by the mode selection unit 108, the first control unit 110 of the control device 100 controls the sheet cutter moving mechanism 34 to move the sheet cutter 33 downward and press the sheet cutter 33 against the cutter pad 19. This makes the recording medium 5 placed on the platen 16 ready to be cut by the sheet cutter 33. The first control unit 110 then controls the second carriage 38 so that it can move independently of the ink head 24 in the main scanning direction Y. This allows the user to manually move the second carriage 38 on which the sheet cutter 33 is mounted. In this way, in manual cutting mode, the second carriage 38 on which the sheet cutter 33 is mounted, which is pressed against the cutter pad 19, can be moved manually, so the recording medium 5 can be manually cut by the sheet cutter 33 without going through a setup operation. Furthermore, when cutting other parts of the recording medium 5, the recording medium 5 can be manually moved in the sub-scanning direction X, allowing it to be manually cut by the sheet cutter 33 without going through a setup operation.

[0068] In the printer 10 of this embodiment, the first control unit 110 controls the second carriage 38 to move independently of the ink head 24 in the main scanning direction Y by stopping the power supply to the carriage motor 44. This allows the user to manually move the second carriage 38 on which the sheet cutter 33 is mounted.

[0069] In this embodiment, the printer 10, the first control unit 110 controls the second carriage 38 to move independently of the ink head 24 in the main scanning direction Y by releasing the connection between the second carriage 38 and the first carriage 28. This allows the user to manually move the second carriage 38, which is equipped with the sheet cutter 33.

[0070] The printer 10 of this embodiment includes a grid roller 57 provided on the platen 16 for moving the recording medium 5 in the sub-scanning direction X, a pinch roller 60 positioned above the grid roller 57 for holding down the recording medium 5, a loading lever 65 for moving the pinch roller 60 vertically, a main body case 10c supporting the platen 16, and a fan 18 for drawing air into the internal space 17 partitioned by the platen 16 and the main body case 10c. The platen 16 has a plurality of suction holes 16H that communicate with and penetrate the internal space 17. The fan 18 is configured to draw air into the internal space 17 through the suction holes 16H. The control device 100 includes a second control unit 112 that drives the fan 18 when the pinch roller 60 is moved downward by the loading lever 65 while the manual cutting mode is selected. With this configuration, the fan 18 is driven by the second control unit 112, causing the recording medium 5 placed on the platen 16 to be attracted to the platen 16. As a result, even after manually cutting the recording medium 5, the recording medium 5 remains attached to the platen 16, thus preventing the recording medium 5 from falling off the platen 16.

[0071] In the printer 10 of this embodiment, the second control unit 112 stops the fan 18 when the pinch roller 60 is moved upward by the loading lever 65 while the manual cutting mode is selected. This allows the user to easily move the recording medium 5 manually in the sub-scanning direction X.

[0072] The printer 10 of this embodiment includes a supply device 70 located behind the platen 16, which rotatably supports a supply shaft 71 extending in the main scanning direction Y and around which the recording medium 5 is wound; a media transfer mechanism 55 provided on the platen 16 for moving the recording medium 5 in the sub-scanning direction X; and a winding device 90 located in front of the platen 16, which rotatably supports a winding shaft 91 extending in the main scanning direction Y and for winding up the recording medium 5 after printing. The media transfer mechanism 55 is configured to move the recording medium 5 in the return direction X2 so that the recording medium 5 is wound up by the supply shaft 71 before it is cut by the sheet cutter 33. With this configuration, after continuously printing an image on a long recording medium 5, the recording medium 5 can be unwound by the supply shaft 71 and then continuously cut by the sheet cutter 33. For example, if the process of printing an image onto the recording medium 5 and then cutting the recording medium 5 with the sheet cutter 33 is repeated multiple times, it is necessary to wind the recording medium 5 onto the winding shaft 91 each time after cutting, and the portion of the recording medium 5 from the ink head 24 to the winding shaft 91 is discarded without being printed. However, since the recording medium 5 can be wound up by the supply shaft 71, it is possible to print images onto the recording medium 5 continuously and then cut the recording medium 5 continuously. This suppresses the generation of wasted material on the recording medium 5.

[0073] Preferred embodiments of the present invention have been described above. However, the embodiments described above are merely illustrative, and the present invention can be implemented in various other forms.

[0074] In the embodiment described above, the first carriage 28 could not move independently in the main scanning direction Y, but other drive sources may be provided to enable the first carriage 28 to move independently. That is, the first carriage 28 and the second carriage 38 may each be able to move independently in the main scanning direction Y.

[0075] In the embodiments described above, the first cutter 27 and the second cutter 37 are roller cutters, but their configuration is not limited as long as they can cut the recording medium 5 in the sub-scanning direction X. That is, the first cutter 27 and the second cutter 37 do not have to be circular blades. [Explanation of Symbols]
