Abstract

This prevents damage to the blade of the second cutter when it moves from a detached state to an attached state. [Solution] The printer 1 includes a cutter 70 and a cutter 60 that cut paper transported by a transport mechanism, and a housing. The cutter 70 is supported by the housing. The cutter 60 is detachable from the housing and can be in an attached state where it is attached to a mounting position X on the housing, and a detached state where it is removed from the mounting position X. Furthermore, in the attached state, the cutter 60 can be in a contact state where it is in contact with the cutter 70, and a non-contact state where the blade portion 60B of the cutter 60 is not in contact with the cutter 70. The cutter 60 takes the non-contact state when it moves from the detached state to the attached state.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In a configuration where the second cutter is detachable from the housing as in Patent Document 1, when the second cutter changes from the detached state where it is removed from the housing to the attached state where it is attached to the housing, there is a risk that the blade portion of the second cutter contacts the first cutter and gets damaged. If the blade portion of the second cutter is damaged, problems may occur in cutting the recording medium.

[0005] Therefore, an object of the present disclosure is to provide a recording apparatus capable of suppressing damage to the blade portion of the second cutter when the second cutter changes from the detached state to the attached state in a configuration where the second cutter is detachable from the housing.

Means for Solving the Problems

[0006] The recording device of this disclosure comprises a transport mechanism for transporting a recording medium, a recording unit for recording an image on the recording medium transported by the transport mechanism, a first cutter and a second cutter for cutting the recording medium transported by the transport mechanism, and a housing. The first cutter is supported by the housing, and the second cutter is detachable from the housing and can be in a mounted state where it is mounted in a mounting position on the housing, and a detached state where it is removed from the mounting position. Furthermore, in the mounted state, the second cutter can be in a contact state where it is in contact with the first cutter so as to cut the recording medium through the cooperation of the blade portion of the first cutter and the blade portion of the second cutter, and in a non-contact state where the blade portion of the second cutter does not come into contact with the first cutter. The second cutter takes the non-contact state when it moves from the detached state to the mounted state. [Effects of the Invention]

[0007] According to the recording device of this disclosure, when the second cutter moves from a detached state to an attached state, the second cutter enters a non-contact state. As a result, when the second cutter moves from a detached state to an attached state, the blade of the second cutter does not come into contact with the first cutter, and damage to the blade of the second cutter can be suppressed.

[Modes for carrying out the invention]

[0009] <First Embodiment> As shown in Figure 1, the printer 1 according to the first embodiment of this disclosure comprises a housing 1A, a paper feed tray 10 that is detachable from the housing 1A, and a paper output tray 20. The printer 1 corresponds to the "recording device" of this disclosure.

[0010] Printer 1 further comprises a transport mechanism 3, a head 5, a cutter unit 6, a cutter 70, a scanning mechanism 4, and a control unit 100, as shown in Figure 2. The transport mechanism 3, head 5, cutter unit 6, scanning mechanism 4, and control unit 100 are supported by the housing 1A.

[0011] In the following description, the vertical direction is defined based on the state in which the printer 1 is installed on the installation surface G in a usable state (state shown in Figure 2), the front-to-back direction is defined with the side of the housing 1A with the opening 1B being the front side (front or forward) and the side of the housing 1A with the opening 1C being the back side (back or rear), and the left-to-right direction is defined when viewing the printer 1 from the front side. The left-to-right direction corresponds to the "first direction" in this disclosure.

[0012] The transport mechanism 3 is configured to transport paper S along the transport path T in the transport direction, and includes rollers 13 and an arm 14, roller pairs 3A to 3C, a separating member 3F, a pair of guide members 3G, and a transport motor (not shown) for driving each of the rollers.

[0013] The transport path T is a path that goes from the paper feed tray 10, through a pair of guide members 3G, under the head 5, and toward the paper output tray 20. The transport path T has a U-shaped section TU on the upstream side in the transport direction relative to the head 5. The separation member 3F, cutter unit 6, cutter 70, roller pair 3A, and the pair of guide members 3G are arranged in the U-shaped section TU. The cutter unit 6, cutter 70, and roller pair 3A are located at the bottom UX of the U-shaped section TU. The cutter unit 6 and cutter 70 are located downstream in the transport direction relative to the separation member 3F and upstream in the transport direction relative to the roller pair 3A.

[0014] The paper feed tray 10 is movable forward through the opening 1B from the state of being mounted on the housing 1A. The paper feed tray 10 includes rollers 51 and 52, a roll paper storage section 11 capable of storing a roll paper R, and a cut paper storage section 12 capable of storing a plurality of cut papers (not shown) stacked in the vertical direction. The cut papers stored in the cut paper storage section 12 are supported on the upper surface of a support plate 19 arranged along the bottom plate 18 of the paper feed tray 10. When using the roll paper R in the paper feed tray 10, the cut papers are removed from the cut paper storage section 12 (see FIG. 2), and when using the cut papers, the roll paper R is removed from the roll paper storage section 11.

[0015] The paper S is a general term for the paper unrolled from the roll paper R and the cut papers, and corresponds to the "recording medium" of the present disclosure. The cut paper refers to a paper having a length shorter than that of the paper constituting the roll paper R along the conveyance path T.

[0016] The roll paper R is formed by winding a long paper S around the outer peripheral surface of a cylindrical core member RC in a roll shape. The roll paper R is stored in the roll paper storage section 11 with its rotation axis RX (the central axis of the core member RC) along the left-right direction.

[0017] The rollers 51 and 52 are arranged at the bottom of the roll paper storage section 11. The rollers 51 and 52 are driven rollers rotatable about an axis along the left-right direction. When the roll paper R is stored in the roll paper storage section 11, the outer peripheral surface of its lower portion is supported by the rollers 51 and 52. When setting the roll paper R, the roll paper R is manually rotated in the direction of arrow Q in FIG. 2 to unwind the paper S from the roll paper R. Then, the paper S is passed through the gap between the lower surface of the support plate 19 and the upper surface of the bottom plate 18, and the leading end of the paper S is sandwiched between the roller 13 and the roller 15. In this state, the conveyance motor is driven under the control of the control unit 100, and when the roller 13 rotates, the paper S unwound from the roll paper R is fed rearward.

[0018] The roller 13 is supported at one end 14A of the arm 14 and is rotatable about an axis 13X along the left - right direction. The other end 14B of the arm 14 is supported by the housing 1A via an axis 14X along the left - right direction. The arm 14 is pivotable about the axis 14X with the other end 14B as a fulcrum.

[0019] When the cut paper is not stored in the cut - paper storage portion 12 in the state where the paper feed tray 10 is attached to the housing 1A, the roller 13 contacts the roller 15 through a notch portion (not shown) of the support plate 19 (see FIG. 2). When the cut paper is stored in the cut - paper storage portion 12 in the state where the paper feed tray 10 is attached to the housing 1A, the roller 13 contacts the uppermost cut paper among the cut papers stored in the cut - paper storage portion 12. At this time, the conveyance motor is driven under the control of the control unit 100, and the roller 13 rotates to feed the cut paper backward.

[0020] The paper S (paper unwound from the roll paper R or cut paper) fed from the paper feed tray 10 by the roller 13 contacts the separating member 3F, moves along the separating member 3F, and is guided to the roller pair 3A.

[0021] The separating member 3F is disposed behind the roller 13 and extends in a diagonal direction intersecting both the up - down direction and the front - rear direction. Fine irregularities are formed on the surface of the separating member 3F along the conveyance path T. The irregularities suppress double feeding (a phenomenon in which a plurality of cut papers are conveyed in an overlapping state). That is, the separating member 3F has a function of separating the cut paper contacting the roller 13 from other cut papers.

[0022] The roller pairs 3A to 3C are arranged in this order from the upstream side in the conveyance direction and convey the paper S conveyed by the roller 13 in the conveyance direction. The roller pair 3A is disposed between the cutter unit and the pair of guide members 3G in the conveyance direction. The roller pair 3A guides the paper S conveyed from the roller 13 to the roller pair 3B.

[0023] Roller pair 3B feeds the paper S guided by roller pair 3A to the head 5. Roller pair 3C ejects the paper S transported by roller pair 3B to the output tray 20. The paper S transported by roller pairs 3B and 3C is fed forward.

[0024] Each roller pair 3A to 3C consists of a drive roller that rotates when driving force is transmitted from the transport motor, and a driven roller that moves along with the drive roller. When the transport motor is driven by the control unit 100, the drive roller and driven roller of roller pair 3A to 3C rotate with the paper S nipping, and the paper S is transported in the transport direction.

[0025] The print head 5 includes a plurality of nozzles (not shown) formed on its lower surface and a driver IC (not shown). The print head 5 corresponds to the "recording unit" in this disclosure. When the paper S transported by the transport mechanism 3 passes a position facing the lower surface of the print head 5, the driver IC is driven by the control unit 100, causing ink to be ejected from the nozzles, the ink to land on the paper S, and an image to be recorded on the paper S. The print head 5 may be either a line-type print head that ejects ink from nozzles while its position is fixed, or a serial-type print head that ejects ink from nozzles while moving in the left-right direction.

[0026] The cutter unit 6 is configured to cut the paper S unwound from the roll paper R between the separating member 3F and the roller pair 3A in the transport path T. The cutter unit 6 includes a cutter 60 and a holder 61 for holding the cutter 60. The cutter unit 6 is also detachably attached to a carriage 8 supported by a housing 1A.

[0027] The carriage 8 is capable of reciprocating in the left-right direction by the scanning mechanism 4. The left-right direction is parallel to the paper S along the transport path T and intersects with the transport direction A (see Figure 2: the transport direction near the cutter unit 6). The scanning mechanism 4 corresponds to the "movement mechanism" in this disclosure.

[0028] As shown in Figure 3, the scanning mechanism 4 includes a guide rail 4X extending in the left-right direction, a pair of pulleys 4A spaced apart from each other in the left-right direction (only one of the pair of pulleys 4A is shown in Figure 3), a belt 4B wound around the pair of pulleys 4A and to which the carriage 8 is fixed, and a cutting motor (not shown). The pair of pulleys 4A and the belt 4B are attached to the guide rail 4X. The guide rail 4X supports the carriage 8 fixed to the belt 4B and the cutter unit 6 mounted on the carriage 8. The guide rail 4X is supported by the housing 1A.

[0029] Another guide rail 4Y is positioned in front of guide rail 4X, opposite guide rail 4X with the transport path T (see Figure 2) in between. Guide rail 4Y extends in the left-right direction and is separated from guide rail 4X in the front-rear direction by a small gap. The transport path T is formed in this gap.

[0030] The guide rail 4Y is supported by the housing 1A. A cutter 70 is attached to the guide rail 4Y. The cutter 70 is a fixed blade fixed to the guide rail 4Y, while the cutter 60 is a disc-shaped rotating blade. Furthermore, the cutter 70 is supported by the housing 1A via the guide rail 4Y, whereas the cutter 60, together with the holder 61, is detachable from the housing 1A (carriage 8). The cutter 60 and the cutter unit 6 including it can be in a mounted state attached to the housing 1A (see Figure 3) and a detached state removed from the mounting position X of the housing 1A.

[0031] Cutter 70 corresponds to the "first cutter" in this disclosure, and cutter 60 corresponds to the "second cutter" in this disclosure. When mounted, cutter 60 cooperates with cutter 70 to cut the paper S transported by the transport mechanism 3. In this embodiment, cutters 60 and 70 are both made of metal material, but they may be made of other materials such as synthetic resin as long as they can cut the paper S.

[0032] As shown in Figures 3 and 4, the cutter 70 extends in a long length in the left-right direction. As shown in Figure 5, the cutter 70 is L-shaped and has a portion 71 that covers the lower surface of the guide rail 4Y and a portion 72 that covers the side surface that defines the transport path T on the guide rail 4Y. The portion 72 of the cutter 70 extends in a first direction D1 along the transport path T and has a base portion 70A and a blade portion 70B provided at the tip of the base portion 70A. The first direction D1 is a direction that intersects the left-right direction and corresponds to the "second direction" of this disclosure.

[0033] As shown in Figure 4, the base portion 70A has a first portion 70A1 and a second portion 70A2. Both the first portion 70A1 and the second portion 70A2 are strip-shaped portions extending in the left-right direction. The first portion 70A1 covers the side surface that defines the transport path T on the guide rail 4Y. The second portion 70A2 is positioned on the portion of the first portion 70A1 excluding the right end, and constitutes a stepped portion 70D that protrudes above the upper surface 70A3 of the first portion 70A1.

[0034] The blade portion 70B of the cutter 70 includes a cutting region 70B1 that works in cooperation with the blade portion 60B of the cutter 60 to cut the paper S, and a non-cutting region 70B2 that is aligned with the cutting region 70B1 in the left-right direction. The cutting region 70B1 is the region where the blade portion 70B is located at the upper end of the second portion 70A2 and extends in the left-right direction. The cutting region 70B1 is also longer than the transport path T in the left-right direction. The transport path T is located within the cutting region 70B1 in the left-right direction.

[0035] The non-cutting region 70B2 is the region where the blade portion 70B is located at the upper end of the right end of the first portion 70A1, that is, downstream in the cutting direction from the cutting region 70B1. Furthermore, the non-cutting region 70B2 is located below the cutting region 70B1 in the first direction D1. In other words, as shown in Figure 4(b), the non-cutting region 70B2 is further away from the cutter 60 than the cutting region 70B1 when the cutter unit 6 is mounted in the mounting position X in the first direction D1.

[0036] Furthermore, the second portion 70A2 has an inclined surface 70A4 at its right end, which is the boundary between the cut region 70B1 and the uncut region 70B2. The inclined surface 70A4 slopes downward as it moves to the right (the cutting direction described later), and its right end is connected to the upper surface 70A3 of the first portion 70A1.

[0037] As shown in Figure 6, the cutter 60 has a disc-shaped base 60A and a blade portion 60B provided on the periphery of the base 60A, and is supported by a holder 61 so as to be rotatable about an axis 60X. As shown in Figure 5(b), when the cutter 60 is mounted, it extends in a second direction D2 that intersects the first direction D1, and the blade portion 60B is positioned in close proximity to the blade portion 70B.

[0038] When the cutting motor (scanning mechanism 4) is driven by the control unit 100, the belt 4B moves in the left-right direction, and the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the home position H outside the transport path T into the transport path T (see Figure 3). At this time, the cutter 60 rotates due to the drive of the cutting motor. The paper S unwound from the roll paper R is cut in the width direction of the paper S by the fixed cutter 70 and the cutter 60 which rotates while moving in the left-right direction.

[0039] Mounting position X, as shown in Figure 3, is located at the right end of the guide rails 4X and 4Y, and is the position for attaching and detaching the cutter unit 6 to the carriage 8. Home position H is located at the left end of the guide rails 4X and 4Y, and is the starting position for cutting the paper S. In other words, when cutting the paper S, the cutter 60 moves from home position H in the cutting direction to the right. When the cutting of the paper S is complete, the cutter 60 moves to the left (opposite direction to the cutting direction) and returns to home position H.

[0040] A sensor E is provided at the home position H, which is electrically connected to the control unit 100. When the cutter unit 6 is in the home position H, the sensor E makes contact with the cutter unit 6 and outputs an ON signal to the control unit 100. When the cutter unit 6 is not in the home position H, the sensor E moves away from the cutter unit 6 and outputs an OFF signal to the control unit 100. When recording using roll paper R, the control unit 100 receives an ON signal from the sensor E and controls the transport motor, driver IC, and cutting motor to perform a recording process that records an image on the paper S.

[0041] An opening 1C (see Figure 2) is formed in the rear wall of the housing 1A. Through the opening 1C, the portion of the housing 1A including the mounting position X (the carriage 8 at mounting position X) is exposed to the outside of the housing 1A. The opening 1C is formed in the portion of the housing 1A that faces the bottom UX of the U-shaped portion TU described above.

[0042] A cover 21 is attached to the rear wall of the housing 1A to cover the opening 1C. The cover 21 is rotatable about an axis 21X that runs in the left-right direction and is provided at the lower end of the opening 1C. By rotating about the axis 21X, it can selectively take on a closed position that closes the opening 1C (see solid line in Figure 2) and an open position that opens the opening 1C (see dashed line in Figure 2).

[0043] The housing 1A is provided with a cover sensor (not shown) electrically connected to the control unit 100. The cover sensor outputs an ON signal to the control unit 100 when the cover 21 is in the open position and an OFF signal to the control unit 100 when the cover 21 is in the closed position. When the control unit 100 receives an ON signal from the cover sensor, it controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the home position H to the mounting position X. This allows the cutter unit 6 to be attached to and detached from the carriage 8 at the mounting position X through the opening 1C by positioning the cover 21 in the open position (see dashed line in Figure 2). Furthermore, when the control unit 100 receives an OFF signal from the cover sensor, it controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the mounting position X to the home position H.

[0044] The carriage 8 has a bottom wall 8T (see Figure 5) and a pair of side walls 8S spaced apart from each other in the left-right direction (only one of the pair of side walls 8S is shown in Figure 3). The cutter unit 6 is positioned between the pair of side walls 8S and is supported on the support surface 8A (see Figure 5), which is the upper surface of the bottom wall 8T. A leaf spring 31 is attached to the support surface 8A. The cutter unit 6 is supported on the support surface 8A with an upward biasing force applied by the leaf spring 31.

[0045] A lever 9 is attached to the carriage 8, as shown in Figure 3. The lever 9 has an axis 9C that runs in the left-right direction and is rotatable relative to the carriage 8 about the axis 9C. The axis 9C is inserted into a hole 8C formed in the side wall 8S of the carriage 8.

[0046] The lever 9 can rotate around the axis 9C to selectively take between a release position (see Figure 5(a)) in which the cutter unit 6 is released from the carriage 8, and a fixed position (see Figure 5(b)) in which the cutter unit 6 is fixed to the carriage 8.

[0047] When mounting the cutter unit 6 onto the carriage 8 at mounting position X, the user, with the lever 9 in the released position (see Figure 5(a)), grasps the handle 61Z provided at the rear end of the holder 61 and moves the cutter unit 6 forward, inserting it between the pair of side walls 8S (see Figure 3) of the carriage 8. This temporarily positions the cutter unit 6 in the left-right direction relative to the carriage 8 by the pair of side walls 8S. At this time, the protrusion 61X provided at the rear end of the holder 61 is positioned within the recess 8X of the carriage 8. Also, the front end of the cutter unit 6 is lifted upward by the biasing force of the leaf spring 31, and the blades 60B and 70B are separated from each other. At this time, the front end 9A of the lever 9 is in contact with the slope 61C formed at the boundary between the upper surface 61A and the front surface 61B of the holder 61.

[0048] Subsequently, by pushing down the rear end 9B of the lever 9, the lever 9 is moved from the release position (see Figure 5(a)) to the fixed position (see Figure 5(b)). At this time, the front end 9A of the lever 9 moves along the inclined surface 61C of the holder 61 and reaches the upper surface 61A of the holder 61. Consequently, the front end 9A of the lever 9 presses against the upper surface 61A of the holder 61, and the cutter unit 6 is pressed toward the support surface 8A against the biasing force of the leaf spring 31. As a result, the cutter unit 6 is fixed to the carriage 8 and becomes mounted. At this time, the distance between the blades 60B and 70B in the first direction D1 is smaller than the distance when the lever 9 is in the release position (see Figure 5(a)), and becomes a predetermined distance suitable for cutting the paper S.

[0049] Here, the positional relationship of the cutter 60 with respect to the cutter 70 will be explained. In this embodiment, as shown in Figure 4(b), when the cutter unit 6 moves from the detached state to the mounted state at the mounting position X of the housing 1A, the blade portion 60B of the cutter 60 faces the non-cutting region 70B2 in the first direction D1. In other words, the cutter 60 takes a non-contact state, away from the blade portion 70B of the cutter 70, so that the blade portion 60B does not come into contact with the blade portion 70B of the cutter 70 in the first direction D1. Then, when the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the mounting position X to the home position H, or from the home position H to the mounting position X, the blade portion 60B of the cutter 60 comes into contact with the blade portion 70B of the cutter 70 when the cutter unit 6 is at a position other than the mounting position X.

[0050] As shown in Figure 4, the cutter 60 is mounted on the holder 61 in a position that is not parallel to the left and right directions, but is tilted diagonally downward to the right when mounted. In other words, as shown in Figure 4(a), the cutter 60 is positioned at an angle to the cutter 70 such that, when in contact, its left end is further away from the cutter 70 along the first direction D1 than its right end. When the cutter unit 6 moves in the cutting direction from the home position H to the mounting position X, the blades 60B and 70B make contact with each other so as to be able to cut the paper S. The left end corresponds to "one end" in this disclosure, and the right end corresponds to "the other end" in this disclosure.

[0051] When removing the cutter unit 6 from the carriage 8 in mounting position X, the user lifts the rear end 9B of the lever 9, moving the lever 9 from the fixed position (see Figure 5(b)) to the released position (see Figure 5(a)). At this time, the front end 9A of the lever 9 moves from the upper surface 61A of the holder 61 to the inclined surface 61C. Consequently, the pressure applied by the front end 9A of the lever 9 is released, and the cutter unit 6 moves upward due to the biasing force of the leaf spring 31, with the convex portion 61X positioned in the concave portion 8X. At this time, the distance between the blade portions 60B and 70B in the first direction D1 becomes larger than the distance when the lever 9 is in the fixed position (see Figure 5(b)).

[0052] Subsequently, with the lever 9 in the release position (see Figure 5(a)), the user grasps the handle 61Z provided at the rear end of the holder 61 and moves the cutter unit 6 backward, pulling it out from the pair of side walls 8S of the carriage 8. This removes the cutter unit 6 from the carriage 8, putting it into a detached state.

[0053] As described above, according to the printer 1 of this embodiment, when the cutter 60 moves from the detached state to the attached state, the cutter 60 takes a non-contact state. As a result, when the cutter 60 moves from the detached state to the attached state, the blade portion 60B of the cutter 60 does not come into contact with the cutter 70, and damage to the blade portion 60B of the cutter 60 can be suppressed.

[0054] The blade portion 70B of the cutter 70 includes a cutting region 70B1 provided at the upper end of the second portion 70A2 that constitutes the stepped portion 70D, and a non-cutting region 70B2 provided at the upper end of the right end of the first portion 70A1. When the cutter 60 moves from a detached state to an attached state, the blade portion 60B of the cutter 60 faces the non-cutting region 70B2 in the first direction D1. This simple configuration of providing a step in the cutter 70 prevents damage to the blade portion 60B of the cutter 60.

[0055] In the configuration in which the cutter 60 is positioned at an angle as described above, if the non-cutting area 70B2 is located upstream to the right (in the cutting direction) relative to the cutting area 70B1, the blade portion 60B of the cutter 60 may come into contact with the boundary portion (the left side of the stepped portion 70D) between the cutting area 70B1 and the non-cutting area 70B2 and be damaged when the cutter 60 moves in the cutting direction. In contrast, in this configuration, since the non-cutting area 70B2 is located downstream to the right (in the cutting direction) relative to the cutting area 70B1, the blade portion 60B of the cutter 60 does not come into contact with the right side of the stepped portion 70D when the cutter 60 moves in the cutting direction. Therefore, damage to the blade portion 60B of the cutter 60 can be avoided.

[0056] <Second Embodiment> Next, with reference to Figure 7, a printer 1 according to the second embodiment of this disclosure will be described. In this embodiment, the printer 1 further includes a roller 201, the mounting position X and home position H are located at the left end of the guide rails 4X, 4Y, and the configuration of the cutter 270 is slightly different from the configuration of the cutter 70 of the first embodiment. Components similar to those in the first embodiment described above are indicated by the same reference numerals and their description is omitted. The cutter 270 corresponds to the "first cutter" of this disclosure.

[0057] The cutter 270 is otherwise the same as the cutter 70 described above, except that it has a portion 272 that extends uniformly in the left-right direction instead of the portion 72 of the first embodiment. The portion 272 extends in a first direction D1 along the transport path T and has a base portion 270A and a blade portion 270B provided at the tip of the base portion 270A. The blade portion 270B of the cutter 270 also has a cutting region 270B1 that cuts the paper S in cooperation with the blade portion 60B of the cutter 60. The cutting region 270B1 extends to the right from the right end of the region of the blade portion 270B that faces the roller 201.

[0058] The roller 201 is positioned between two guide rails 4X and 4Y and is supported in front of guide rail 4X. In other words, the roller 201 is supported by the housing 1A via guide rail 4X. Note that the roller 201 may also be supported by the housing 1A via members other than guide rail 4X.

[0059] As shown in Figure 7(a), the roller 201 is positioned at the left end of the guide rail 4X. The roller 201 is rotatably supported about an axis 201X that intersects both the left-right direction and the first direction D1. The axis 201X corresponds to the “axis of rotation” in this disclosure.

[0060] The roller 201 is positioned so that its upper part protrudes above the blade portion 270B of the cutter 270. More specifically, as shown in Figure 7(c), the upper end of the roller 201 is positioned above the left end of the cutter 60 in the contact state. The contact state refers to the state in which the blade portion 60B of the cutter 60 comes into contact with the blade portion 270B of the cutter 270 when the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the mounting position X (home position H) to the right end of the guide rails 4X, 4Y, or when the cutter unit 6 moves from the right end of the guide rails 4X, 4Y to the mounting position X (home position H), while the cutter unit 6 is in a position other than the mounting position X.

[0061] The cutter 60 is positioned to be movable vertically in the axial direction of the shaft 60X. The cutter 60 is also biased downward in the axial direction by a spring (not shown).

[0062] With this configuration, when the cutter unit 6 moves from the detached state to the mounted state at the mounting position X of the housing 1A, the base 60A of the cutter 60 comes into contact with the circumferential surface 201A of the roller 201, as shown in Figure 7(a). In other words, the circumferential surface 201A comes into contact with the base 60A of the cutter 60, excluding the blade portion 60B. As a result, the cutter 60 takes a non-contact state in which the blade portion 60B is separated from the blade portion 270B of the cutter 270 in the first direction D1. The circumferential surface 201A corresponds to the "contact portion" in this disclosure.

[0063] When cutting the paper S unwound from the roll paper R, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move in the cutting direction to the right from the home position H (i.e., mounting position X), as shown in Figure 7(b). At this time, since the cutter 60 is biased downward by a spring, as it moves from the home position H in the cutting direction, the blade portion 60B at the right end of the cutter 60 approaches the blade portion 270B of the cutter 270 and comes into contact with it.

[0064] When the cutting of the paper S unwound from the roll paper R is complete, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move to the left, in the opposite direction to the cutting direction, as shown in Figure 7(c). At this time, just before the cutter 60 returns to the home position H, the left end of the cutter 60 comes into contact with the circumferential surface 201A of the roller 201. As the cutter 60 moves to the left while in contact with the roller 201, the roller 201 rotates counterclockwise in Figure 7, lifting the cutter 60 upward. In this way, the cutter 60 takes a non-contact state where the blade portion 60B is separated from the blade portion 270B. Also, because the roller 201 rotates when the cutter 60 is moved toward the home position H (i.e., mounting position X), it is possible to prevent the blade portion 60B of the cutter 60 from digging into the circumferential surface 201A of the roller 201. Therefore, damage to the blade portion 60B of the cutter 60 can be avoided.

[0065] In this embodiment, when the cutter 60 moves from the detached state to the mounted state, the portion of the cutter 60 other than the blade portion 60B comes into contact with the circumferential surface 201A of the roller 201, resulting in a non-contact state. As a result, the blade portion 60B of the cutter 60 does not come into contact with the cutter 270, thus preventing damage to the blade portion 60B of the cutter 60. Furthermore, because the cutter 60 comes into contact with the circumferential surface 201A when moving from the detached state to the mounted state, the position of the cutter 60 is maintained. Therefore, the cutter 60 is less likely to come close to the cutter 270, effectively preventing the blade portion 60B of the cutter 60 from coming into contact with the cutter 270.

[0066] Furthermore, the contact point that the cutter 60 makes when moving from the detached state to the attached state is the circumferential surface of the roller 201. As a result, the cutter 60 can be smoothly moved from the attached position X along the left-right direction as the roller 201 rotates.

[0067] Furthermore, when the scanning mechanism 4 cuts the paper S, it moves the cutter 60 from the home position H (i.e., the mounting position X) in the cutting direction. In the printer 1 of the first embodiment, the home position H and the mounting position X are at different ends of the guide rails 4X and 4Y. Therefore, space is required at the home position H and the mounting position X to accommodate the carriage 8, which increases the length of the printer 1 in the left-right direction. In contrast, in this embodiment, the mounting position X and the home position H are at the same position. Therefore, it is possible to reduce the length of the printer 1 in the left-right direction.

[0068] <Third Embodiment> Next, with reference to Figure 8, a printer 1 according to the third embodiment of this disclosure will be described. The printer 1 in this embodiment is substantially the same as the printer 1 of the second embodiment, except that it is equipped with a chute member 301 instead of the roller 201 described above. Components similar to those in the first and second embodiments described above are indicated by the same reference numerals and their descriptions are omitted. The chute member 301 corresponds to the "contact portion" in this disclosure.

[0069] The blade portion 270B of the cutter 270 has a cutting region 270B1 that works in cooperation with the blade portion 60B of the cutter 60 to cut the paper S. The cutting region 270B1 extends to the right from the right end of the region of the blade portion 270B that faces the chute member 301.

[0070] The chute member 301 is positioned between two guide rails 4X and 4Y and is supported in front of the guide rail 4X. In other words, the chute member 301 is supported by the housing 1A via the guide rail 4X. The chute member 301 may also be supported by the housing 1A via members other than the guide rail 4X.

[0071] As shown in Figure 8(a), the chute member 301 is positioned at the left end of the guide rail 4X. The chute member 301 extends in the first direction D1 and in the left-right direction. Furthermore, in the first direction D1, the upper part of the chute member 301 is positioned so as to protrude above the blade portion 270B, so as to protrude towards the cutter 60 side of the cutter 270. More specifically, as shown in Figure 8(c), the upper end of the chute member 301 is positioned below the left end of the cutter 60 facing the cutting area 270B1 and towards the cutter 270 side. This makes it possible to move the cutter 60 onto the chute member 301 when moving it to the mounting position X by moving it to the left in the opposite direction to the cutting direction.

[0072] A radius 302 is provided at the upper right corner of the chute member 301. This allows the cutter 60 to smoothly ride onto the chute member 301 when it is moved to the mounting position X by moving it to the left.

[0073] With this configuration, when the cutter unit 6 moves from the detached state to the mounted state at the mounting position X of the housing 1A, the base portion 60A of the cutter 60 comes into contact with the upper end of the chute member 301, as shown in Figure 8(a). In other words, the upper end of the chute member 301 comes into contact with the base portion 60A of the cutter 60, excluding the blade portion 60B. As a result, the cutter 60 takes a non-contact state in which the blade portion 60B is separated from the blade portion 270B of the cutter 270 in the first direction D1.

[0074] When cutting the paper S unwound from the roll paper R, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move in the cutting direction to the right from the home position H (i.e., mounting position X), as shown in Figure 8(b). At this time, since the cutter 60 is biased downward by a spring, as it moves from the home position H in the cutting direction, the blade portion 60B at the right end of the cutter 60 approaches the blade portion 270B of the cutter 270 and comes into contact with it.

[0075] When the cutting of the paper S unwound from the roll paper R is complete, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move to the left, in the opposite direction to the cutting direction, as shown in Figure 8(c). At this time, just before the cutter 60 returns to the home position H, the bottom surface of the cutter 60 comes into contact with the radius 302 of the chute member 301. As the cutter 60 moves to the left while in contact with the radius 302, it is lifted upward by the chute member 301. In this way, the cutter 60 takes a non-contact state.

[0076] In this embodiment, when the cutter 60 moves from the detached state to the attached state, the part of the cutter 60 other than the blade portion 60B comes into contact with the upper end of the chute member 301, resulting in a non-contact state. As a result, the blade portion 60B of the cutter 60 does not come into contact with the cutter 270, and damage to the blade portion 60B of the cutter 60 can be suppressed. In addition, because the cutter 60 comes into contact with the upper end of the chute member 301 when moving from the detached state to the attached state, the posture of the cutter 60 is maintained. Therefore, the cutter 60 is less likely to come close to the cutter 270, and contact between the blade portion 60B of the cutter 60 and the cutter 270 can be effectively suppressed.

[0077] The upper part of the chute member 301 protrudes above the cutter 270. This effectively prevents the blade portion 60B of the cutter 60 from coming into contact with the cutter 270 when the cutter 60 moves from the detached state to the attached state.

[0078] <Fourth Embodiment> Next, with reference to Figure 9, a printer 1 according to the fourth embodiment of this disclosure will be described. In this embodiment, the printer 1 has its mounting position X and home position H at the left end of the guide rails 4X, 4Y, and the configuration of the cutter 470 differs from that of the cutter 70 in the first embodiment. Components similar to those in the first embodiment described above are indicated by the same reference numerals and their descriptions are omitted. The cutter 470 corresponds to the "first cutter" in this disclosure.

[0079] The cutter 470 extends lengthwise in the left-right direction. The base 470A of the cutter 470 has a first portion 470A1 and a second portion 470A2. Both the first portion 470A1 and the second portion 470A2 are strip-shaped portions that extend in the left-right direction. The first portion 470A1 covers the side surface that defines the transport path T on the guide rail 4Y. The second portion 470A2 is positioned on the left end of the first portion 470A1 and constitutes a stepped portion 470D that protrudes above the upper surface 470A3 of the first portion 470A1.

[0080] The blade portion 470B of the cutter 470 includes a cutting region 470B1 that works in cooperation with the blade portion 60B of the cutter 60 to cut the paper S, and a non-cutting region 470B2 that is aligned with the cutting region 470B1 in the left-right direction. The cutting region 470B1 is a region where the blade portion 470B is located at the upper end portion of the first portion 470A1, excluding the left end, and extends in the left-right direction.

[0081] The non-cutting region 470B2 is the region where the blade portion 470B is located at the upper end of the second portion 470A2, that is, upstream of the cutting region 470B1 in the cutting direction. Also, the non-cutting region 470B2 is above the cutting region 470B1 in the first direction D1. In other words, as shown in Figure 9(a), the cutting region 470B1 is further away from the cutter 60 than the non-cutting region 470B2 in the first direction D1. The stepped portion 470D constitutes the boundary between the cutting region 470B1 and the non-cutting region 470B2.

[0082] In this configuration, when the cutter unit 6 moves from a detached state to a mounted state at mounting position X of the housing 1A, the base portion 60A of the cutter 60 comes into contact with the rightmost corner of the stepped portion 470D, as shown in Figure 9(a). In other words, the rightmost corner of the stepped portion 470D comes into contact with the base portion 60A of the cutter 60, excluding the blade portion 60B. As a result, the cutter 60 takes a non-contact state in which the blade portion 60B is separated from the cutter 470 (blade portion 470B) in the first direction D1. The stepped portion 470D corresponds to the "contact portion" in this disclosure. This contact portion can be provided by a simple configuration of providing a step in the cutter 470.

[0083] When cutting the paper S unwound from the roll paper R, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move in the cutting direction to the right from the home position H (i.e., mounting position X), as shown in Figure 9(b). At this time, since the cutter 60 is biased downward by a spring, as it moves from the home position H in the cutting direction, the blade portion 60B at the right end of the cutter 60 approaches the blade portion 470B of the cutter 470 and comes into contact with it.

[0084] Furthermore, the right end of the second portion 470A2, which is the downstream end in the cutting direction, has an inclined surface 470A4 at the boundary between the cutting region 470B1 and the non-cutting region 470B2. The inclined surface 470A4 slopes downward as it progresses in the cutting direction, and its right end connects to the upper surface 470A3 of the first portion 470A1.

[0085] As shown in Figure 9(b), the upstream end of the inclined surface 470A4 in the cutting direction is further away from the cutting area 470B1 than the left end of the cutter 60 in the first direction D1 when the blade portion 60B of the cutter 60 is in contact with the blade portion 470B of the upper surface portion 470A3 of the first portion 470A1. In other words, the upstream end of the inclined surface 470A4 in the cutting direction is positioned above the left end of the cutter 60. The contact state refers to the state in which the blade portion 60B of the cutter 60 comes into contact with the blade portion 470B of the cutter 470 when the carriage 8 and the cutter unit 6 mounted on the carriage 8 move from the mounting position X (home position H) to the right end of the guide rails 4X, 4Y, or when the cutter unit 6 moves from the right end of the guide rails 4X, 4Y to the mounting position X (home position H), while the cutter unit 6 is in a position other than the mounting position X.

[0086] The inclination angle θ1, which is the angle of the inclined surface 470A4 with respect to the left-right direction, is greater than the acute angle θ2 formed between the cutter 60 and the cutting area 470B1 of the cutter 470 when the cutter 60 is in contact, as shown in Figure 9(c), and is less than or equal to twice the angle θ2. The inclination angle θ1 is the angle obtained by subtracting the obtuse angle θ3 formed between the inclined surface 470A4 and the cutting area 470B1 (upper surface 470A3) of the cutter 470 from 180°.

[0087] When the cutting of the paper S unwound from the roll paper R is complete, the control unit 100 controls the cutting motor so that the carriage 8 and the cutter unit 6 mounted on the carriage 8 move to the left, in the opposite direction to the cutting direction, as shown in Figure 9(c). At this time, just before the cutter 60 returns to the home position H, the left end of the cutter 60 comes into contact with the inclined surface 470A4. As the cutter 60 moves to the left, it moves upward along the inclined surface 470A4. When the cutter 60 returns to the home position H, where the base 60A comes into contact with the rightmost corner of the stepped portion 470D, it enters a non-contact state.

[0088] When the cutter 60 is moved along the inclined surface 470A4 to the home position H (i.e., the mounting position X), the acute angle θ4 between the inclined surface 470A4 and the cutter 60 becomes less than or equal to angle θ2. In other words, the angle θ4 of the left end of the cutter 60 with respect to the inclined surface 470A4 when the cutter 60 moves in the reverse direction from the cutting area 470B1 to the non-cutting area 470B2 is less than or equal to the angle θ2 of the right end of the cutter 60 with respect to the cutting area 470B1 when the cutter 60 moves in the cutting direction from the non-cutting area 470B2 to the cutting area 470B1. Therefore, even if the blade portion 60B at the left end of the cutter 60 comes into contact with the inclined surface 470A4 when the cutter 60 is moved in the reverse direction, the blade portion 60B is less likely to be damaged.

[0089] In this embodiment, when the cutter 60 moves from the detached state to the attached state, the part of the cutter 60 other than the blade portion 60B comes into contact with the rightmost corner of the stepped portion 470D, thus creating a non-contact state. As a result, the blade portion 60B of the cutter 60 does not come into contact with the cutter 470, and damage to the blade portion 60B of the cutter 60 can be suppressed. In addition, because the cutter 60 comes into contact with the rightmost corner of the stepped portion 470D when moving from the detached state to the attached state, the posture of the cutter 60 is maintained. Therefore, the cutter 60 is less likely to come close to the cutter 470, and contact between the blade portion 60B of the cutter 60 and the cutter 470 can be effectively suppressed.

[0090] The blade portion 470B of the cutter 470 includes a non-cutting region 470B2 provided at the upper end of the second portion 470A2 that constitutes the stepped portion 470D, and a cutting region 470B1 provided at the upper end of the first portion 470A1 excluding the left end. When the cutter 60 moves from a detached state to an attached state, the blade portion 60B of the cutter 60 faces the non-cutting region 70B2 in the first direction D1. This simple configuration of providing a step in the cutter 70 prevents damage to the blade portion 60B of the cutter 60.

[0091] While preferred embodiments of this disclosure have been described above, this disclosure is not limited to the embodiments described above, and various modifications are possible as long as they are within the scope of the claims.

[0092] In each of the embodiments described above, the cutter 60 included in the cutter unit 6 is disc-shaped and rotates, but is not limited to this and may be fixed to the cutter unit 6. The cutter unit 6 may also cut cut paper.

[0093] The inclined surfaces 70A4 and 470A4 may extend along a direction perpendicular to the left-right direction (first direction D1) if the upper end of the first direction D1 is closer to the cutters 70 and 470 than the left end of the cutter 60. Also, the inclination angle θ1 may be greater than twice the angle θ2.

[0094] The recording medium is not limited to paper; it may also be cloth or plastic film. In other words, the recording medium may be made of any material. Furthermore, the recording medium is not limited to a sheet form.

[0095] The head 5, acting as the recording unit, may eject liquids other than ink (for example, a processing liquid that causes components in the ink to coagulate or precipitate). Furthermore, the recording unit is not limited to a liquid ejection method, but may also use a laser method, a thermal transfer method, or the like.

[0096] This disclosure is not limited to printers, but is also applicable to facsimile machines, copiers, multifunction devices, etc. [Explanation of Symbols]
