[0007] The present invention will now be briefly described. The media transport device of the first aspect comprises a device main body having a transport path for transporting a medium, an outer door, an inner door arranged inside the outer door with respect to the device main body, an outer hinge that attaches the outer door to the device main body so that it can be opened and closed, and an inner hinge that attaches the inner door to the device main body so that it can be opened and closed, wherein the rotation axis of the outer hinge and the rotation axis of the inner hinge both extend in a first direction, and the outer hinge and the inner hinge are arranged in positions that overlap when viewed from a direction intersecting with the outer door surface of the outer door in a closed state.

[0008] According to this aspect, the outer hinge and the inner hinge are arranged at positions where they overlap when viewed from a direction intersecting with the outer door surface of the outer door in the closed state. In other words, the positions of the outer hinge and the inner hinge are close to each other, so that the device can be made compact. In addition, since both the outer door and the inner door are configured to be attached to the device body, the outer door and the inner door can be in various states, such as closing the outer door and the inner door, opening the outer door and the inner door, removing the inner door with the outer door open, or opening the outer door and closing the inner door.

[0009] The medium conveying device of the second aspect is characterized in that, in the first aspect, the device body has a fixing surface for fixing the internal hinge, and the fixing surface is arranged so as to be inclined at an acute angle with respect to the surface of the outer door when the outer door is in a closed state.

[0010] Generally, if the position of the outer hinge and the position of the inner hinge are close to each other, it is difficult to remove the inner door while the outer door is still attached. This is because the outer door gets in the way and makes it difficult to access the inner hinge. However, according to this embodiment, the fixing surface is arranged to be inclined at an acute angle with respect to the outer door surface of the outer door in the closed state. This makes it possible to prevent the outer door from getting in the way and making it difficult to access the inner hinge, and makes it easy to remove the inner door with the outer door open.

[0011] The medium conveying device of the third aspect is characterized in that, in the first aspect, the device body has a fixing surface for fixing the internal hinge with a fixing member, and the fixing surface is positioned such that the fixing member does not interfere with the external door in an open state when the internal hinge is fixed with the fixing member.

[0012] According to this aspect, the fixing surface is arranged so that the fixing member does not interfere with the outer door in the open state when the inner hinge is fixed with the fixing member. Therefore, it is possible to prevent the fixing member from interfering with the outer door, making it difficult to fix the inner hinge to the fixing surface, and it is easy to remove the inner door with the outer door open.

[0013] The medium conveying device according to a fourth aspect is any one of the first to third aspects, further comprising a regulating portion that regulates an opening angle of the outer door.

[0014] According to this aspect, the restricting portion restricts the opening angle of the outer door, which makes it possible to prevent the outer door from opening too far and colliding with an external device, an external wall, or the like.

[0015] The media conveying device of the fifth aspect is characterized in that, in any one of the first to fourth aspects, the inner door, when closed, together with the device main body forms at least a part of the first conveying path of the conveying path.

[0016] According to this aspect, when the inner door is closed, it constitutes at least a part of the first transport path together with the device body. The inner door also serves as at least a part of the first transport path, which can simplify the device configuration. In addition, by opening the inner door together with the outer door, if a transport failure occurs with the medium on the first transport path, the medium can be easily removed.

[0017] The media transport device of the sixth aspect is characterized in that, in the fifth aspect, the inner hinge is positioned outside the transport area of ​​the medium in the first transport path in a width direction intersecting the transport direction of the medium.

[0018] According to this aspect, the inner hinge is disposed outside the transport area of ​​the medium on the first transport path in the width direction, which makes it possible to prevent the medium being transported on the first transport path from interfering with the inner hinge.

[0019] The media conveying device of the seventh aspect is characterized in that, in any one of the first to sixth aspects, the inner door, when in a closed state, together with the outer door in a closed state, forms at least a part of a second conveying path of the conveying path.

[0020] According to this aspect, when the inner door is closed, it constitutes at least a part of the second transport path together with the outer door in the closed state. The inner door also serves as at least a part of the second transport path, so that the device configuration can be simplified. In addition, when the outer door is opened, if a transport failure occurs in the second transport path, the medium can be easily removed.

[0021] The medium conveying device of the eighth aspect is characterized in that, in any one of the first to seventh aspects, the inner door has a mounting surface of the inner hinge that intersects with the outer door surface of the outer door when the inner door is in a closed state, and the inner hinge is positioned so that it does not protrude from the mounting surface of the inner hinge when viewed from the direction opposite to the mounting surface of the inner hinge.

[0022] According to this aspect, the inner hinge is disposed so as not to protrude from the mounting surface of the inner hinge when viewed from the direction opposite to the mounting surface of the inner hinge. This prevents the inner hinge from interfering with the device body or the outer door, so that the inner door can be disposed close to the device body and the outer door, thereby making the device more compact.

[0023] The medium conveying device of the 9th aspect is any one of the first to eighth aspects, characterized in that the device body has a holding section that holds a detachable first unit by removing the inner door, and the holding section is positioned on the opposite side of the outer door in a closed state with respect to the inner door in a closed state.

[0024] According to this aspect, the device body has a holding section that holds the first unit that can be attached and detached by removing the inner door. Therefore, various first units can be attached to the device body. In addition, the holding section is disposed on the opposite side of the outer door in a closed state with respect to the inner door in a closed state, and when attaching or detaching the first unit, the inner door can be easily removed with the outer door open.

[0025] The medium conveying device according to a tenth aspect is the medium conveying device of the ninth aspect, further comprising the first unit.

[0026] According to this aspect, the first unit is provided, and therefore various processes can be performed on the medium transported to the first unit.

[0027] The media transport device of the 11th aspect is characterized in that, in the 10th aspect, the device main body is capable of connecting a second unit to the first unit without removing the inner door, and the first unit is a transport unit that transports the media to the second unit.

[0028] According to this aspect, the first unit is configured to be connectable to the second unit and is a transport unit that transports the medium to the second unit, and therefore various processes can be performed on the medium transported to the second unit via the transport unit.

[0029] The medium conveying device according to a twelfth aspect is the medium conveying device of the eleventh aspect, further comprising the second unit, the second unit being configured to be capable of conveying the medium to an external device.

[0030] According to this aspect, it is possible to transport the medium to the external device, and therefore various processes can be performed on the medium transported to the external device.

[0031] A recording device according to a thirteenth aspect includes the medium conveying device according to any one of the first to eleventh aspects, and a recording unit that records on the medium.

[0032] According to the present aspect, in a recording device having an outer door and an inner door, the size of the device can be prevented from increasing, while the outer door and the inner door can each be in a variety of states, such as leaving the outer door open and the inner door closed.

[0033] Hereinafter, as an embodiment, a specific example of a recording device as an example of a medium conveying device according to the present invention will be described. A printer 10 as a recording device or a part thereof is shown in FIG. 1 to FIG. 22. The printer 10 is configured as an inkjet type device that performs recording by ejecting ink Q, which is an example of a liquid, onto paper P, which is an example of a medium. The XYZ coordinate system shown in each figure is an orthogonal coordinate system. The X direction is the device width direction when viewed from the operator of the printer 10, and is a horizontal direction. The arrow direction of the X direction is the +X direction, and the opposite direction to the arrow direction is the -X direction. The Y direction is the width direction that intersects with the conveying direction of the paper P and the device depth direction, and is a horizontal direction. The arrow direction of the Y direction is the +Y direction, and the opposite direction to the arrow direction is the -Y direction. The Z direction is an example of the device height direction, and is a vertical direction. The arrow direction that is upward in the Z direction is the +Z direction, and the opposite direction to the arrow direction that is downward in the Z direction is the -Z direction. In this embodiment, "upward" means a direction that includes an upward component in the Z direction. "Down" means a direction that has a downward component in the Z direction.

[0034] 1, in the printer 10, the paper P is transported through a transport path T indicated by a dashed line. The direction in which the paper P is transported on the transport path T differs at each portion of the transport path T. The printer 10 includes a device main body 12, a transport unit 20, a feed unit 50, and a line head 28.

[0035] The device body 12 includes a case 11 that serves as an outer shell, and a number of frames 60 as shown in Fig. 2 and the like. In the +Z direction from the center in the Z direction of the device body 12, an ejection section 13 is formed, which includes a space into which the recorded paper P is ejected. The device body 12 is also provided with a number of paper cassettes 14. An outer opening 12A that opens in the X direction is formed at the end of the device body 12 in the -X direction. The device body 12 is provided with an outer door 30 that opens and closes the outer opening 12A.

[0036] As shown in Figs. 2 to 4, the outer door 30 is formed in a substantially plate-like shape having a predetermined thickness. As shown in Figs. 4 and 5, the outer door 30 has an outer hinge 31 provided at the end of the device body 12 in the -X direction and the end in the -Y direction as a rotation axis 15 along the Z direction. This allows the outer door 30 to rotate around an axis along the Z direction. The outer door 30 opens or closes the outer opening 12A as it rotates around the rotation axis 15, thereby opening and closing a part of the conveying path T1 and the reversing path T4, which are part of the conveying path T. In other words, the outer door 30 can be rotated between an open position that exposes a part of the conveying path T1 and the reversing path T4, and a closed position that hides the conveying path T1 and the reversing path T4. As shown in Fig. 1, a part of the outer door 30 forms the conveying path T1, and another part forms the reversing path T4.

[0037] In addition, the device body 12 is provided with an inner door 40, which is an opening / closing door, on the inside of the outer door 30 on the +X direction side, i.e., inside the outer opening 12A. As shown in Figs. 3 and 4, the inner door 40 is formed in a substantially plate shape having a predetermined thickness. As shown in Fig. 4, the inner door 40 has an inner hinge 41 provided at the end of the device body 12 in the -X direction and the end in the -Y direction, i.e., at a position close to the outer hinge 31, as a rotation axis 5 along the Z direction. This allows the inner door 40 to rotate around an axis along the Z direction. The inner door 40 opens or closes the inner opening 12B as it rotates around the rotation axis 5, thereby opening and closing a part of the conveying path T1 and the reversing path T4, which are parts of the conveying path T. In other words, the outer door 30 is rotatable between an open position that exposes a part of the conveying path T3 and a closed position that hides the conveying path T3. 1, a part of the inner door 40 forms the transport path T3, and another part forms the reversing path T4. In other words, the inner door 40 constitutes at least a part of the transport path T3 as the first transport path and the reversing path T4 as the second transport path.

[0038] As shown in FIG. 1, a plurality of paper cassettes 14 store paper P. The paper P stored in the paper cassette 14 is transported along a transport path T by a pick roller 16 and a pair of transport rollers 17 and 18. The transport path T is a junction of a transport path T1 along which the paper P is transported from an external device (not shown) and a transport path T2 along which the paper P is transported from a manual feed tray 19 provided in the device body 12 via a feed roller 66. The area in the -X direction from the center in the X direction of the printer 10 is configured as a transport unit 20 that transports the paper P. The feed unit 50 is provided on the periphery of the manual feed tray 19 at the end of the printer 10 in the -X direction. The paper P on the manual feed tray 19 is fed along the transport path T2 by the feed unit 50, and then transported along the transport path T by the transport unit 20.

[0039] The transport section 20 includes a transport belt 22 wound around two pulleys 21, a pair of registration rollers 23 for performing skew correction and the like for the paper P, a plurality of transport roller pairs 24 for transporting the paper P, a plurality of flaps 25 for switching the path along which the paper P is transported, and a medium width detection unit 26 for detecting the width of the paper P in the Y direction. Downstream of the transport belt 22 in the transport path T are provided a transport path T3 toward the discharge section 13 and a reversing path T4 for reversing the front and back of the paper P. When the inner door 40 is closed as shown in FIG. 1, a surface 40A on the +X direction side together with the device body 12 constitutes the transport path T3, and a surface 40B on the -X direction side together with a surface 30A on the +X direction side of the outer door 30 in the closed state constitutes a reversing path T4.

[0040] The transport path T3 is provided with an outlet E1 and an outlet E2 for discharging the paper P. However, in the state shown in FIG. 1, the flap 25 allows the paper P to be discharged from the outlet E1 to the discharge section 13. The printer 10 of this embodiment is configured to allow various units to be attached to the +X direction side of the inner opening 12B in the device main body 12, and by attaching a desired unit, various processes can be performed on the paper P discharged from the outlet E1 and the outlet E2.

[0041] The device body 12 is also provided with an ink tank 27 that contains ink Q, and a control unit 29 that is a control board that controls the operation of each part of the printer 10. The line head 28 is located downstream of the medium width detection unit 26 in the transport direction of the paper P and in a position facing the transport belt 22. The line head 28 is also an example of a recording unit, and performs recording by ejecting ink Q supplied from the ink tank 27 onto the paper P fed from the feed unit 50.

[0042] The control unit 29 is configured to include a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage (not shown), and controls the transport of paper P in the printer 10 and the operation of each part including the line head 28, the transport unit 20, and the feed unit 50.

[0043] 5 to 10, how the outer door 30 and the inner door 40 are attached to the device body 12 will be described below. In particular, the configurations and arrangements of the outer hinge 31 that attaches the outer door 30 to the device body 12 and the inner hinge 41 that attaches the inner door 40 to the device body 12 will be mainly described.

[0044] 5 is a view with the case 11 partially removed, and as shown in FIG. 5, the printer 10 has two external hinges 31 attached to the frame 60 at the end on the -Y direction side of the -X direction side of the device body 12. As shown in FIGS. 7 and 8, the external hinge 31 has a frame fixing part 310 that is fixed to the frame 60, and an external door fixing part 311 that is fixed to the external door 30. The frame fixing part 310 has a flat plate part 310A that is screwed to the frame 60 with screws 52, a flat plate part 310B that is perpendicular to the flat plate part 310A in a plan view seen from the Z direction, and holes 310C provided in two places, one at the +Z direction end and one at the -Z direction end of the flat plate part 310B. The outer door fixing part 311 has a screw fastening part 311A ​​that is screwed to the outer door 30, and a hole forming part 311B in which a plurality of holes 311C are provided. A rod-shaped member 312 is provided that passes from the hole 310C at the +Z direction end part through the plurality of holes 311C to the hole 310C at the -Z direction end part. The rod-shaped member 312 forms the rotation axis 15.

[0045] 5, the printer 10 of this embodiment is configured so that the outer hinge 31 can be exposed when the outer door 30 is closed, and so that the outer hinge 31 can be attached to and detached from the outside of the device body 12 when the outer door 30 is closed. This configuration allows the components of the printer 10 to be effectively arranged inside the outer door 30. If the outer hinge 31 could not be attached to and detached from the device body 12 from the outside when the outer door 30 was closed, and the outer hinge 31 was attached and detached from the outer opening 12A side, which is on the inside of the device body 12, when the outer door 30 was open, it would be difficult to access the outer hinge 31 depending on the arrangement of the components of the printer 10 inside the outer door 30.

[0046] As shown in FIG. 6, the inner hinge 41 is attached near the outer hinge 31. In detail, the inner hinge 41 is attached to the frame 60 at the end of the -X direction side and the -Y direction side of the device body 12, at a position overlapping the outer hinge 31 when viewed from the X direction. In this way, the inner hinge 41 is provided on the same side as the outer hinge 31 with respect to the device body 12, so that the inner door 40 can be automatically closed by closing the outer door 30 when both the outer door 30 and the inner door 40 are open. In addition, since both the outer door 30 and the inner door 40 are attached to the end of the -X direction side and the -Y direction side of the device body 12, the worker can access the outer opening 12A from the front side, that is, the +Y direction side, and the outer door 30 can be prevented from being an obstacle to work. Note that the frame 60 to which the outer hinge 31 is attached and the frame 60 to which the inner hinge 41 is attached are different frames, but they may be attached to the same frame 60. 9 and 10, the inner hinge 41 has a frame fixing part 410 fixed to the frame 60 and an inner door fixing part 411 fixed to the inner door 40. The frame fixing part 410 has a flat plate part 410A screwed to the frame 60 and a hole forming part 410B in which holes 410C are provided at two locations, a +Z direction end and a -Z direction end. The inner door fixing part 411 has a flat plate part 411A screwed to the inner door 40 and a hole forming part 411B in which holes 411C are provided at two locations, a +Z direction end and a -Z direction end. A rod-shaped member 412 is provided which passes from hole 410C at the end of the flat plate portion 411A in the +Z direction through hole 411C of hole forming portion 411B to hole 410C at the end of the flat plate portion 411A in the -Z direction. The rod-shaped member 412 forms a rotation axis 5.

[0047] 6, in the printer 10 of this embodiment, the fixing surface 60A of the frame 60 that fixes the inner hinge 41 is disposed at an acute angle in a plan view relative to the Y direction, that is, the outer door surface 30B of the outer door 30 in the closed state. Note that in the printer 10 of this embodiment, the acute angle Θ is 30°, and is preferably between 30° and 45°, but is not limited to this range of angles, as shown in FIG.

[0048] In summary, the printer 10 of this embodiment includes an apparatus body 12 having a transport path T for transporting paper P, an outer door 30, an inner door 40 disposed inside the outer door 30 with respect to the apparatus body 12, an outer hinge 31 that mounts the outer door 30 to the apparatus body 12 so as to be openable and closable, and an inner hinge 41 that mounts the inner door 40 to the apparatus body 12 so as to be openable and closable. The rotation shaft 15 of the outer hinge 31 and the rotation shaft 5 of the inner hinge 41 both extend in the Z direction as a first direction, and the outer hinge 31 and the inner hinge 41 are disposed in positions that overlap when viewed from the X direction, which is a direction intersecting with the outer door surface 30B of the outer door 30 in a closed state.

[0049] In this way, by arranging the outer hinge 31 and the inner hinge 41 at positions where they overlap when viewed from the X direction, the outer hinge 31 and the inner hinge 41 can be positioned close to each other, thereby making it possible to miniaturize the device. Also, by configuring both the outer door 30 and the inner door 40 to be attached to the device body 12, in addition to the outer door 30 and the inner door 40 being in a closed state or in an open state, the outer door 30 and the inner door 40 can each be in various states, such as removing the inner door 40 with the outer door 30 open, or opening the outer door 30 and closing the inner door 40. In addition, "arranging the outer hinge 31 and the inner hinge 41 in a position where they overlap when viewed from the X direction" includes an arrangement in which the outer hinge 31 and the inner hinge 41 completely overlap when viewed from the X direction, as well as an arrangement in which the outer hinge 31 and the inner hinge 41 only partially overlap when viewed from the X direction.

[0050] From another perspective, the printer 10 of this embodiment is a medium transport device, and also a recording device that includes a line head 28 that records on paper P. Therefore, in a recording device having an outer door 30 and an inner door 40, it is possible to suppress an increase in size of the device, while allowing the outer door 30 and the inner door 40 to be in various states, such as keeping the outer door 30 open and the inner door 40 closed.

[0051] As described above, the device body 12 has a fixing surface 60A for fixing the inner hinge 41, and the fixing surface 60A is disposed so as to be inclined at an acute angle with respect to the outer door surface 30B of the outer door 30 in the closed state. Generally, if the positions of the outer hinge 31 and the inner hinge 41 are close to each other, it becomes difficult to remove the inner door 40 while the outer door 30 is attached. This is because the outer door 30 gets in the way and makes it difficult to access the inner hinge 41. However, in the printer 10 of this embodiment, the fixing surface 60A is disposed so as to be inclined at an acute angle with respect to the outer door surface 30B of the outer door 30 in the closed state. This makes it possible to prevent the outer door 30 from getting in the way and making it difficult to access the inner hinge 41, and makes it easy to remove the inner door 40 with the outer door 30 open.

[0052] 6 and 13 described later, the device body 12 has a fixing surface 60A to which the inner hinge 41 is fixed by screws 51 that are fixing members, and the fixing surface 60A is arranged so that the screws 51 do not interfere with the outer door 30 in the open state when the inner hinge 41 is fixed by the screws 51. Therefore, the printer 10 of this embodiment can prevent the screws 51 from interfering with the outer door 30 and making it difficult to fix the inner hinge 41 to the fixing surface 60A, and can easily remove the inner door 40 with the outer door 30 open. Note that an arrangement in which the fixing member does not interfere with the outer door 30 includes not only a case in which the fixing member itself does not interfere with the outer door 30, but also a case in which it is possible to prevent interference with tools such as a screwdriver when the fixing member is the screw 51 as in the printer 10 of this embodiment.

[0053] The arrangement and configuration of the outer door 30 and the inner door 40 will be described in more detail below with reference to Figures 11 to 17. As shown in Figures 11 and 12, the inner door 40 is substantially flat with a surface 40A and a surface 40B facing opposite directions, and is attached by screwing an inner hinge 41 to a mounting surface 40C located at the end of the surface 40A and the surface 40B in the -Y direction.

[0054] In other words, the inner door 40 has a mounting surface 40C of the inner hinge 41, which is an XZ plane that intersects with the YZ plane that is the outer door surface 30C of the outer door 30 in the closed state. As shown in FIG. 12, the inner hinge 41 is disposed so as not to protrude from the mounting surface 40C when viewed from the Y direction, which is the direction facing the mounting surface 40C. With this configuration, interference of the inner hinge 41 with the device main body 12 and the outer door 30 can be suppressed. For this reason, in the printer 10 of this embodiment, as shown in FIG. 14, the inner door 40 can be disposed close to the device main body 12 and the outer door 30, and the device can be made compact. As shown in Figure 14, the gap G1 between the inner door 40 and the device main body 12 forms a transport path T3 as the first transport path, and the gap G2 between the inner door 40 and the outer door 30 forms an inversion path T4 as the second transport path, but the gap G1 and gap G2 can be made narrow.

[0055] The printer 10 of this embodiment can use paper P of various sizes, but when the largest size of paper P is used, the position corresponding to the end of the paper P in the -Y direction, which is the width direction, is the width direction end position L1 of the largest medium, represented by a dashed line in Figure 13. Here, as shown in Figure 13, the position of the inner hinge 41 is on the -Y direction side of the width direction end position L1 of the largest medium.

[0056] In other words, the inner hinge 41 is disposed outside the medium transport area in the transport path T3 as the first transport path and the inversion path T4 as the second transport path in the width direction intersecting with the transport direction of the paper P. Therefore, the printer 10 of this embodiment can prevent the paper P being transported on the transport path T3 and the inversion path T4 from interfering with the inner hinge 41. Note that the printer 10 of this embodiment is disposed outside the medium transport area in the width direction with respect to both the transport path T3 and the inversion path T4. However, this is not limited to such a configuration, and may be configured such that, for example, the inner hinge 41 is disposed outside the medium transport area in the width direction with respect to one of the transport path T3 and the inversion path T4. However, it is preferable that the inner hinge 41 is disposed outside the medium transport area in the width direction with respect to at least the transport path T3.

[0057] Furthermore, in the printer 10 of this embodiment, the opening angle of the outer door 30 is restricted. Fig. 15 shows the outer door 30 in its fully open state. In other words, the printer 10 of this embodiment is provided with a restricting unit 6 that restricts the opening angle of the outer door 30, as shown in Figs. 16 and 17. For this reason, the printer 10 of this embodiment is configured to prevent the outer door 30 from opening too far and colliding with an external device, an external wall, or the like.

[0058] 16 and 17, the printer 10 of the present embodiment is configured to allow cables such as a USB cable 7 and a power cable to be connected to the case 11. For this reason, by configuring the printer 10 of the present embodiment to allow cables and the like to be arranged in the case 11 of the device body 12, the printer 10 can prevent the outer door 30 from opening too far and colliding with the cables or a wall around the installation location by configuring the outer door 30 to be regulated. The restricting portion 6 of the present embodiment has an XZ plane, and is configured to restrict the opening angle of the outer door 30 by abutting the XZ plane against the open outer door surface 30B. The restricting portion 6 is not particularly limited in configuration, and may be a string-like member or a spring-loaded member that restricts the outer door 30 from opening too far, in addition to a configuration such as a contact portion with the outer door 30 that abuts against the open outer door 30 as the restricting portion 6 of the present embodiment to restrict the outer door 30 from opening too far, or may be a cable attached to the device body 12 that also serves as the restricting portion 6.

[0059] In the printer 10 of this embodiment, the outer door 30 and the inner door 40 are configured and arranged as described above. With the outer door 30 and the inner door 40 configured and arranged as described above, when the inner door 40 is closed, it constitutes at least a part of the transport path T3, which is the first transport path of the transport path for the paper P, together with the device body 12. In this way, the inner door 40 also serves as at least a part of the first transport path, which can simplify the device configuration. Furthermore, by opening the outer door 30 or opening the inner door 40 together with the outer door 30, if a transport failure occurs with the paper P on the transport path T3, which is the first transport path, the paper P can be easily removed.

[0060] Furthermore, when the inner door 40 is closed, it constitutes, together with the outer door 30 in the closed state, at least a part of the reversing path T4, which is the second transport path of the transport path for the paper P. In this way, the device configuration can be simplified by the inner door 40 also serving as at least a part of the second transport path. Furthermore, by opening the outer door 30, if a transport failure occurs with the paper P in the reversing path T4, which is the second transport path, the paper P can be easily removed.

[0061] The printer 10 of this embodiment can be connected to various units and external devices. Among the various units, there is a first unit configured to be attached and detached from the inner opening 12B side after removing the inner door 40 from the device body 12, and a second unit that can be connected to the first unit from the outside of the device body 12 without removing the inner door 40 from the device body 12. Examples of the first unit include the medium transport unit 100, a switching unit for the transport path of the paper P, and a sensor unit, which will be described later, and examples of the second unit include a post-processing unit 70, a relay unit 81, and a paper discharge tray and a stapler (finisher) unit, which are attached separately from the discharge unit 13, which will be described later. Examples of external devices include a stapler device, which will be described later. Hereinafter, examples of mounting various units and external devices in the printer 10 of this embodiment will be described in more detail with reference to FIG. 18 to FIG. 22.

[0062] 18, the inner door 40 can be removed from the device body 12. When removing the inner door 40 from the device body 12, the inner door 40 can be easily removed from the device body 12 by removing the screw 51 that fastens the fixing surface 60A of the frame 60 of the device body 12 to the flat plate portion 410A of the frame fixing portion 410 of the inner hinge 41 using a screwdriver, without the screw 51 or the screwdriver interfering with the outer door 30 or the like.

[0063] As shown in FIG. 18, a first discharge outlet guide section 90 is provided in the inner opening 12B, which is an area inside the inner door 40 on the +X direction side of the inner door 40. The first discharge outlet guide section 90 serves to guide the discharge direction of the paper P transported through the transport path T3 so that the paper P heads toward the first discharge outlet E1 instead of the second discharge outlet E2. The first discharge outlet guide section 90 can also be regarded as the first unit. The first discharge outlet guide section 90 is fastened to the frame 60 of the device body 12 with the screw 53, and can be easily removed from the device body 12 by using a screwdriver with the inner door 40 removed from the device body 12, as shown in FIG. 19.

[0064] The medium transport unit 100 can be attached to the printer 10 in the state shown in FIG. 19, for example, as shown in FIG. 20. Here, the first discharge port guide section 90 can be attached to and detached from the holding section 60B as the frame 60 provided in the space 12C inside the inner opening 12B. Then, the medium transport unit 100 can be attached to the holding section 60B after the first discharge port guide section 90 is removed. In detail, the medium transport unit 100 is attached to the holding section 60B by fitting the screw 54 through the medium transport unit 100 into the screw hole 60C formed in the holding section 60B. The medium transport unit 100 also switches the transport path of the paper P, as will be described later. Note that units that can be attached to the printer 10 are not limited to the medium transport unit 100. In addition, the medium transport unit 100 of this embodiment is configured to be attached to the device main body 12 in the +X direction via the inner opening 12B, but may be configured to be attached to the device main body 12 from the outside in the -X direction.

[0065] In the printer 10 of this embodiment, the length in the Y direction of the first discharge outlet guide section 90 and the medium transport unit 100 is longer than the length in the Y direction of the inner door 40, so the first discharge outlet guide section 90 cannot be taken out and the medium transport unit 100 cannot be attached unless the inner door 40 is removed from the device body 12, but this is not limited to a configuration. The length in the Y direction of the first discharge outlet guide section 90 and the medium transport unit 100 may be shorter than the length in the Y direction of the inner door 40, so that the first discharge outlet guide section 90 can be taken out with the inner door 40 attached to the device body 12 and opened, or the medium transport unit 100 can be attached with the inner door 40 attached to the device body 12 and opened.

[0066] Here, by mounting the medium transport unit 100, the printer 10 of this embodiment can guide the discharge direction of the paper P so that the paper P transported along the transport path T3 heads toward the second discharge port E2 instead of the first discharge port E1. Conversely, when the paper P is discharged toward the first discharge port E1 instead of the second discharge port E2, the first discharge port guide section 90 is mounted. Then, as shown in FIG. 21, for example, a post-processing unit 70 can be mounted as a second unit whose transport path is connected to the second discharge port E2. There is no particular limitation on the type of the post-processing unit 70, and for example, a sensor unit that detects the paper P, a mounting unit that mounts the discharged paper P, a drying unit that dries the ink ejected on the paper P, a stapler unit that can bind multiple papers P together, a unit that can perform punching, and the like can be used. Also, instead of the medium transport unit 100, the post-processing unit 70 may be configured to be directly mounted on the device main body 12. In this case, the transport path of the post-processing unit 70 may be connected to the first discharge outlet E1 instead of the second discharge outlet E2.

[0067] Here, the post-processing unit 70 shown in FIG. 21 can be connected to the device main body 12 as a whole, and the unit constitutes a part of the printer 10. Meanwhile, the printer 10 of this embodiment may be configured to be able to connect to an external device that is a device separate from the printer 10, as shown in FIG. 22, for example. In FIG. 22, an intermediate unit 81 as a second unit connected to the first discharge port E1 or the second discharge port E2, and a post-processing unit 80 as an external device connected to the intermediate unit 81 are shown in addition to the printer 10. Here, the intermediate unit 81 can be considered to constitute a part of the printer 10, and can also be considered to be an external device separate from the printer 10. Here, for example, the post-processing unit 70 can be considered to be able to be placed on the printer 10, and the post-processing unit 80 can be considered to be installed separately from the printer 10. Like the post-processing unit 70, the post-processing unit 80 is not particularly limited in type, and may be, for example, a drying device that dries the ink ejected onto the paper P, a stapler device that can staple multiple sheets of paper P together, or a device that can perform punching, saddle-stitching, etc.

[0068] As described above, the device body 12 has the holding part 60B that holds the first unit of various configurations that can be attached and detached by removing the inner door 40, such as the first discharge port guide part 90. The holding part 60B is disposed on the +X direction side of the inner door 40, that is, on the opposite side of the outer door 30 in the closed state with the inner door 40 in the closed state as a reference. In this way, since the device body 12 has the holding part 60B that holds the first unit that can be attached and detached by removing the inner door 40, various first units can be attached to the device body 12. Furthermore, the first unit is disposed on the opposite side of the outer door 30 in the closed state with the inner door 40 in the closed state as a reference, but when attaching and detaching the first unit, the inner door 40 can be easily removed with the outer door 30 open. Furthermore, by regarding the printer 10 as one device equipped with the first unit, various processes can be performed on the medium transported to the first unit.

[0069] 22, the device body 12 can connect the relay unit 81 as the second unit to the medium transport unit 100 as the first unit without removing the inner door 40. The medium transport unit 100 is a transport unit that transports the paper P to the relay unit 81. With this configuration, it is possible to perform various processes on the paper P transported to the second unit via the first unit by using the second unit or an external device that can perform the desired process.

[0070] 22 includes the relay unit 81 as the second unit, and the relay unit 81 is configured to be able to transport paper P to the post-processing device unit 80, which is an external device. Therefore, by using an external device capable of performing desired processing in this manner, various processes can be performed on the transported paper P.

[0071] The relay unit 81 may be used together with the medium transport unit 100 as in this embodiment, or may be used in place of the medium transport unit 100. There are no particular limitations on the units or external devices.

[0072] Although the embodiment of the present invention is based on the configuration described above, it is of course possible to modify or omit a part of the configuration without departing from the scope of the present invention. For example, the present invention includes a configuration in which an external device such as a post-processing device unit 80 is connected to the second unit, and also includes a configuration in which an external device is not connected to the second unit and the second unit can execute a desired process.
