Description

[Technical Field]

[0001] The present disclosure relates to a recording device, and more particularly to a recording device configured to have a replaceable separating member for preventing multiple feeding of recording media. [Background technology]

[0002] Recording devices such as printers and copiers are equipped with a feeding unit that feeds recording media to a recording unit using a feeding roller. This feeding unit is equipped with a separating member such as a separating roller that separates the recording media one by one to prevent double feeding, where two or more recording media are fed at once.

[0003] However, the separating member may become worn due to friction with the recording medium, causing the separating member to deteriorate and reducing its performance in separating the recording medium. Therefore, the recording device includes a configuration for replacing a separating member whose performance in separating the recording medium has decreased due to wear. Patent Document 1 discloses a recording device equipped with a replaceable separation roller, and the recording device disclosed in Patent Document 1 replaces the separation roller by opening the exterior cover and removing the roller mounting unit to which the separation roller is attached.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The embodiments for carrying out the present disclosure will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, and relative positions of the components of the embodiments described below may be changed as appropriate depending on the configuration and various conditions of the recording device to which the present disclosure is applied. The scope of the present disclosure is not limited to the embodiments described below.

[0011] <Embodiment 1> Fig. 1(a) is a perspective view showing a recording device 1 according to this embodiment. As shown in Fig. 1(a), in the recording device 1, a reading device 3 is provided on the top of a main body 2 so as to be able to be opened and closed freely, and a touch panel type display device 4 for receiving user operations is provided on one side of the main body 2.

[0012] Fig. 1(b) is a perspective view showing the open state of the recording device 1 according to this embodiment. As shown in Fig. 1(b), when the recording device 1 is in the open state, the main body 2 of the recording device 1 is opened and the ink tank cover 5 provided on the main body 2 is opened, revealing the ink inlet 6, through which ink can be injected into the ink tank 7.

[0013] 1(a) and 1(b), arrows X, Y, and Z, which are perpendicular to each other, respectively represent the width, depth, and height directions of the recording device 1. Furthermore, arrows X, Y, and Z in FIGS. 2 to 13 represent the same directions as those shown in FIG.

[0014] The recording device 1 in this embodiment is a serial type inkjet recording device that records an image by ejecting ink supplied from an ink tank 7 onto a recording medium, but the present invention can also be applied to other types of serial type recording devices.

[0015] In this embodiment, "recording" not only includes the formation of meaningful information such as characters and figures, but also includes the formation of images, patterns, designs, etc. on a recording medium, or the processing of the medium, regardless of whether the information is meaningful or insignificant, and whether it is visible to humans or not. The recording medium in this embodiment is sheet-like, and more specifically, sheet-like paper may be used as the recording medium. In other embodiments, the recording medium may be cloth, plastic film, etc.

[0016] Fig. 2 is a perspective view showing the recording device 1 according to this embodiment, excluding a part of the main body 2, and Fig. 3 is a cross-sectional view showing a schematic view of the inside of the recording device 1 according to this embodiment, excluding a part of the main body 2. As shown in Figs. 2 and 3, the recording device 1 includes a first feeding unit 20, a second feeding unit 30, a transport unit 40, and a discharge unit 50 to transport a recording medium 200.

[0017] In this embodiment, the sub-scanning direction, which is the direction in which the recording medium 200 is transported, is the Y direction when viewed in a plan view of the recording device 1, and further, the source of the recording medium 200 is defined as the upstream side, and the destination of the recording medium 200 is defined as the downstream side.

[0018] The recording device 1 in this embodiment has a first feeding path for feeding the recording medium 200 from the first feeding unit 20 and a second feeding path for feeding the recording medium 200 from the second feeding unit 30, and can selectively use the first feeding path and the second feeding path to feed the recording medium 200.

[0019] Specifically, the first feeding unit 20 includes three feeding rollers 21, 22, and 23 having an axial direction parallel to the X direction. The feeding rollers 21 and 22 are configured to rotate by the driving force of a driving source 25 (e.g., a motor) and to transport the recording medium 300 loaded on a loading tray 24 disposed at the rear of the main body 2.

[0020] The loading platform 24 of the recording apparatus 1 in this embodiment can be expanded from a stored state as shown in FIG. 1(a) to an open state as shown in FIG.

[0021] The second feeding unit 30 is installed at the bottom of the main body 2 of the recording device 1 and includes a feeding cassette 31 that is detachably attached to the front of the main body 2 of the recording device 1 along the Y direction. The recording medium 200 stored in the feeding cassette 31 is fed to the transport unit 40, bypassing the rear side of the main body 2 of the recording device 1. Specifically, the recording medium 200 stored in the feeding cassette 31 is pressed against the feeding roller 61 by a pressure plate 65, and is fed by the rotation of the feeding roller 61. The recording medium 200 passes through a first separation roller 62 and a second separation roller 63, both of which serve as separating members, and then passes through a transport path P1 formed by being sandwiched between the guide portion 70 and the internal guide 32 of the main body 2. The separation action of the first separation roller 62 and the second separation roller 63 will be described later with reference to FIG. 5. After passing through the transport path P1, the recording medium 200 passes through a transport path P2 formed by being sandwiched between the internal guide 32 and the upper surface guide 33, and then reaches the transport unit 40. The guide portion 70 that constitutes this conveying path is configured to be detachable from the main body 2, as will be described later with reference to FIG. 6 etc., and this allows the second separation roller 63 to be replaced.

[0022] The transport unit 40 is disposed downstream of the first feeding unit 20 and includes a transport roller 41 having an axial direction parallel to the X direction. The rotation of a drive source 43 (for example, a motor) is transmitted to the transport roller 41 via drive transmission means 44, 45, thereby allowing the transport roller 41 to rotate so as to transport the recording medium 200 or the recording medium 300 transported from the first feeding unit 20 or the second feeding unit 30. In detail, the transport roller 41 is pressed against a driven roller 42, and the recording medium 200 or the recording medium 300 is transported while being sandwiched in the nip portion between the transport roller 41 and the driven roller 42.

[0023] The discharge unit 50 is disposed downstream of the transport unit 40 and includes a discharge roller 51 having an axial direction parallel to the X direction. The rotation of the drive source 43 is transmitted to the discharge roller 51 via four drive transmission means 44, 45, 46, and 47, thereby allowing the discharge roller 51 to rotate so as to discharge the recording medium 200 or 300 transported from the transport unit 40. In this embodiment, the discharge roller 51 is pressed against a spur 52, and the recording medium 200 or 300 is transported while being sandwiched in the nip portion between the discharge roller 51 and the spur 52.

[0024] The recording unit 10 is configured to record an image on the recording medium 200 or 300. The recording unit 10 includes a carriage 11. The recording head 12 mounted on the bottom of the carriage 11 includes a plurality of ejection ports for ejecting ink, and ejects ink supplied from the ink tank 7 shown in FIG. 1 via an ink supply tube (not shown) to record an image on the recording medium 200 or 300 transported by the transport unit 40.

[0025] 2 and 3 includes a drive mechanism 16 that reciprocates the carriage 11 in a predetermined direction (main scanning direction). In this embodiment, the main scanning direction, which is the direction in which the carriage 11 reciprocates, is the X direction shown in FIG. 2. The movement of the carriage 11 is defined as scanning, and recording an image with the recording head 12 while moving the carriage 11 is defined as recording scanning. The drive mechanism 16 for driving the carriage 11 includes a guide rail 14 for guiding the movement of the carriage 11 in the main scanning direction, and a belt transmission mechanism 15 that transmits driving force from a drive source 13 (e.g., a motor) to the carriage 11 to move it in the main scanning direction.

[0026] In this embodiment, the recording medium 300 or recording medium 200 fed from the first feeding unit 20 or the second feeding unit 30 is intermittently transported by the transport unit 40, and the transport of the recording medium 300 or recording medium 200 and the recording of an image by the recording unit 10 are performed alternately.

[0027] Specifically, the transport unit 40 transports the recording medium 200 or 300 to a line position (position in the sub-scanning direction) where an image is to be formed on the recording medium, and stops at that line position. While the transport of the recording medium 200 or 300 is stopped, the carriage 11 is moved to perform a recording scan. Next, the transport unit 40 transports the recording medium 200 or 300 to the next line position, and the same procedure is repeated. This allows the image to be recorded on the entire recording medium 200 or 300. When the image recording is completed, the discharge unit 50 discharges the recording medium 200 or 300 from the main body 2.

[0028] Fig. 4 is an enlarged cross-sectional view of a portion a of the recording device shown in Fig. 3. As shown in Fig. 4, the feed roller 61 and the first separation roller 62 are rotatably attached to a first holder 64 fixed to the main body 2.

[0029] The pressure plate 65, which is installed in the storage space of the feed cassette 31, can rotate around a rotation center 65a. When the pressure plate 65 is rotated around the rotation center 65a by a drive source (not shown), one end of the pressure plate 65 rises, and the recording media 200 loaded in the feed cassette 31 come into contact with and are pressed against the feed roller 61.

[0030] Here, when the recording medium 200 comes into contact with the feed roller 61 and the feed roller 61 rotates, the recording medium 200 is transported to the nip portion between the first separation roller 62 and the second separation roller 63. In detail, the driving force provided by the drive source 25 is transmitted to the feed roller 61 and the first separation roller 62, causing the feed roller 61 and the first separation roller 62 to rotate so as to transport the recording medium 200 to the transport path P1 (downstream side).

[0031] The second separation roller 63 is rotatably attached to an arm 66, and the arm 66 is fixed to a second holder 67 so as to be rotatable around a rotation center 66a. A torque limiter (not shown) is provided at the rotation center of the second separation roller 63, and the arm 66 is biased by a spring 68, so that the second separation roller 63 is pressed against the first separation roller 62. When multiple recording media 200 are conveyed to the nip portion between the first separation roller 62 and the second separation roller 63 in an overlapping state due to friction between the recording media 200, the recording media 200 come into contact with a wall surface 67a of the second holder 67, and several recording media 200 are separated and conveyed to the nip portion between the first separation roller 62 and the second separation roller 63.

[0032] FIG. 5A is a diagram illustrating the forces acting on a recording medium 200 as it passes through the nip between the first separation roller 62 and the second separation roller 63 of the recording device according to this embodiment. As shown in FIG. 5A, a single recording medium 200 enters the nip between the first separation roller 62 and the second separation roller 63, and the recording medium 200 receives a force F1 in the feeding direction from the rotating first separation roller 62. This force F1 causes the second separation roller 63 to rotate, but the torque limiter prevents it from rotating. As a result, the recording medium 200 receives the force F1 in the direction opposite to the feeding direction. This force F1 generates a clockwise moment about the center of rotation 66a in the second separation roller 63 and the arm 66, increasing the pressure force N between the first separation roller 62 and the second separation roller 63. As this pressure force N increases, it exceeds the limit of the torque limiter of the second separation roller 63, causing the second separation roller 63 to rotate, allowing the recording medium 200 to pass through the nip. That is, if the conveyance resistance set by a torque limiter (not shown) provided on the second separation roller 63 is T and the friction coefficient between the first separation roller 62 and the second separation roller 63 and the recording medium 200 is μ1, when the relationship F1=μ1N>T is satisfied, that is, when the force F1 becomes greater than the conveyance resistance T, the torque limiter will rotate freely and the second separation roller 63 will rotate in response. This causes the recording medium 200 to be fed downstream. Note that even when the recording medium 200 is not present in the nip portion between the first separation roller 62 and the second separation roller 63, the second separation roller 63 can rotate in response to the first separation roller 62 in a similar manner.

[0033] 5(b) is a diagram illustrating how one recording medium 200 is separated and conveyed from a plurality of recording media 200 by the first separation roller 62 and the second separation roller 63 of the recording device according to this embodiment, i.e., how double feeding is prevented. As shown in FIG. 5(b), when two recording media 200 enter the nip portion between the first separation roller 62 and the second separation roller 63, the coefficient of friction μ2 between the two recording media 200 is smaller than the coefficient of friction μ1 between the first separation roller 62 and the second separation roller 63 and the recording media 200. In other words, the relationship between the force F1 that the upper recording medium 200 receives from the first separation roller and the force F2 that the upper recording medium 200 receives from the lower recording medium 200 is F1=μ1N>F2=μ2N. Furthermore, when the conveying resistance T is appropriately set by the torque limiter, F1 = μ1N>T>F2 = μ2N, and because the conveying resistance T is greater than the force F2, the torque limiter stops the rotation of the second separation roller 63, stopping the feeding of the lower recording medium 200. As a result, the force F1 that the upper recording medium 200 receives from the first separation roller is greater than the force F2 that the upper recording medium 200 receives from the lower recording medium 200, so the two recording media 200 slide against each other, and only the upper recording medium 200 passes through the nip portion and is fed.

[0034] FIG. 6(a) is a perspective view showing a state in which the guide unit 70 of the recording device 1 according to this embodiment is attached to the main body 2, and FIG. 6(b) is a perspective view showing a state in which the guide unit 70 of the recording device 1 according to this embodiment is detached from the main body 2. As shown in FIG. 6(b), the guide unit 70 has a guide surface 70p and an exterior surface 70e facing the guide surface 70p. The guide surface 70p, together with the internal guide 32 (see FIG. 3), forms a transport path P1 (see FIG. 3) for transporting the recording medium 200. The guide unit 70 is attached to the storage unit 26 of the main body 2 with the guide surface 70p facing the storage unit 26 of the main body 2. In the attached state, the exterior surface 70e of the guide unit 70 is exposed and connected to the exterior of the main body 2, as shown in FIG. 6(a).

[0035] The structure for attaching and detaching the guide portion 70 to and from the main body 2 will be described below.

[0036] 7(a) and (b) are cross-sectional views showing the configuration of attachment and detachment of a guide unit 70 according to a first embodiment of the present disclosure. An operation unit 72c is provided on the restricting portion 72 of the guide unit 70, an operation window 71a is formed in the housing 71 of the guide unit 70, and the operation unit 72c is exposed to the outside of the operation window 71a. A user can move the two operation units 72c close to each other in the operation window 71a along the operation direction H (FIG. 7(b)).

[0037] 7(a), the guide part 70 has two restricting parts 72, and a spring 74 is disposed between the two restricting parts 72. The elastic force of the spring 74 urges each restricting part 72 outward in the X direction from inside the housing 71 of the guide part 70. This allows the protruding part 72b of each restricting part 72 to fit into a first positioning hole 81 formed in the second side surface 26a of the accommodation part 26 of the main body 2.

[0038] Furthermore, each of the restricting portions 72 of the guide portion 70 has an elongated sliding groove 72a formed obliquely with respect to the X direction, with a boss portion 76a of the movable portion 76 engaging with this. With this configuration, when the restricting portions 72 are urged and moved toward the outside of the guide portion 70 by the elastic force of the springs 74, as described above, the boss portion 76a of the movable portion 76 moves along the sliding groove 72a in the Z direction and in the opposite direction. This movement allows the protruding portions 76b of the movable portion 76 to fit into second positioning holes 83 formed in the fourth side surface 26b adjacent to the second side surface 26a of the accommodation portion 26.

[0039] When attaching the guide unit 70 to the main body 2, as described above, the user inserts their finger into the operation portion 72c and moves the restricting unit 72 along the operation direction H. As a result, the protrusions 72b of the restricting unit 72 and the protrusions 76b of the movable unit 76 are housed within the guide unit 70 (see FIG. 7(b)). Then, in this state, the guide unit is placed at a predetermined position in the accommodation portion 26 of the main body 2, and the user removes their finger from the operation portion 72c, thereby causing the restricting unit 72 to move as described above. This movement of the restricting units 72 causes the protrusions 72b of the restricting units 72 to fit into the first positioning holes 81, and in conjunction with this, the protrusions 76b of the movable unit 76 fit into the second positioning holes 83, and the guide unit 70 is attached to and fixed to the main body 2.

[0040] On the other hand, when removing the guide part 70 from the main body 2, the user inserts his / her finger into the operating part 72c to move the restricting part 72 in the H direction (see FIG. 7(b)). This causes the protruding part 72b of the restricting part 72 to disengage from the first positioning hole 81 and move back to the first side surface 70a of the guide part 70. In addition, the protruding part 76b of the restricting part 72 disengages from the second positioning hole 83. As a result, the guide part 70 can be removed from the main body 2.

[0041] The guide portion may include only the protrusion 72b of the restricting portion 72, and the guide portion may be attached to the main body simply by fitting the protrusion 72b into the first positioning hole 81.

[0042] In this embodiment, the first positioning hole 81 is formed at the center of the second side surface 26a, and the protruding portion 72b of the regulating portion 72 may be able to protrude or retract to the center of the first side surface 70a, and the second positioning hole 83 is formed at the center of the fourth side surface 26b, and the protruding portion 76b of the movable portion 76 is able to protrude or retract to the center of the third side surface 70b. This makes it possible to suppress deformation of the guide portion 70 when the guide portion 70 is attached to the main body 2 and the first separation roller 62 and the second separation roller 63 rotate to feed the recording medium 200, and to reduce feeding problems of the recording medium 200 caused by changes in the relative positions of the first separation roller 62 and the second separation roller 63.

[0043] The second separation roller 63, which is part of the separation roller of the recording device 1, is attached to the guide unit 70 (see FIGS. 3 and 4). Therefore, by removing the guide unit 70 from the main body 2, the second separation roller 63 can be removed from the main body 2 together with the guide unit 70. Then, it becomes possible to replace the second separation roller 63 whose separation performance has deteriorated due to wear or the like with a new second separation roller 63. Then, the guide unit 70 replaced with the new separation roller is attached to the main body 2 by the above-mentioned operation.

[0044] 8(a), when the guide unit 70 is removed from the main body 2, the second holder 67 to which the second separation roller 63 is attached is exposed from the main body 2, allowing the user to touch the second holder 67. Furthermore, as shown in FIG. 8(b), the second holder 67 is pulled out from the guide unit 70 along the Y direction and separated from the guide unit 70 together with the second separation roller 63. Here, the second holder 67 equipped with a new second separation roller 63 is attached to the guide unit 70, and by attaching it to the main body 2 together with the guide unit 70, replacement of the second separation roller 63 is completed.

[0045] On the other hand, when attaching the second holder 67 to the guide part 70, the flange part 67c of the second holder 67 is slid in the groove part 71h of the guide part 70 along the Y direction. The boss parts 67b of the second holder 67 are fitted into the fitting holes 71g of the guide part 70, thereby attaching the second holder 67 to the guide part 70. The angle and position of the second holder 67 with respect to the guide part 70 can be determined by the angle of the groove part 71h with respect to the flange part 67c and the position of the fitting holes 71g with respect to the boss parts 67b.

[0046] 5, the force F1 shown in Fig. 5 is opposite to the direction in which second holder 67 is removed, and the direction of the pressure contact force N shown in Fig. 5 is substantially perpendicular to flange portion 67c. As a result, when recording medium 200 is fed, second holder 67 is not subjected to a force in a direction in which it would come off guide portion 70, so that it is possible to achieve both ease of replacement of second holder 67 and the function of holding second holder 67 to guide portion 70.

[0047] Furthermore, if the feed roller 61 and the first separation roller 62 are deteriorated and are no longer able to convey the recording medium 200, it is necessary to replace them with new feed rollers 61 and new first separation rollers 62. As shown in FIG. 9(a), when the guide unit 70 is separated from the main body 2, the housing unit 26 of the main body 2 is exposed, allowing the user to access the first holder 64 to which the feed roller 61 and the first separation roller 62 are attached. As a result, as shown in FIG. 9(b), the first holder 64 is pulled out from the main body 2 along the Y direction and separated from the main body 2 together with the feed roller 61 and the first separation roller 62. As a result, the first holder 64 equipped with the new feed roller 61 and the new first separation roller 62 is attached to the main body 2, completing the replacement of the feed roller 61 and the first separation roller 62.

[0048] When attaching the first holder 64 to the main body 2, the flange portion 64a of the first holder 64 is slid in the groove portion 17 of the main body 2 along the Y direction. Furthermore, the boss portions 64b of the first holder 64 are fitted into the fitting holes 18 of the guide portion 70, thereby attaching the first holder 64 to the main body 2. The angle and position of the first holder 64 with respect to the main body 2 can be determined by the angle of the groove portion 17 with respect to the flange portion 64a and the position of the fitting holes 18 with respect to the boss portions 64b.

[0049] 5, the force F1 shown in Fig. 5 is opposite to the direction in which the first holder 64 is removed, and the direction of the pressing force N shown in Fig. 5 is substantially perpendicular to the flange portion 64a. As a result, when the recording medium 200 is fed, the first holder 64 is not subjected to a force in a direction in which it would be removed from the main body 2, so that it is possible to achieve both ease of replacement of the first holder 64 and the function of holding the first holder 64 to the main body 2.

[0050] As described above, in the recording device 1 of this embodiment, the main body 2 and the guide unit 70 can be easily attached and detached, and therefore the feed roller 61, the first separation roller 62, and the second separation roller 63 can be easily replaced. In other words, the technology described in this specification can contribute to the realization of a sustainable society, such as a carbon-free / recycling-based society.

[0051] <Embodiment 2> The embodiment shown in Figures 10-11 shows an alternative similar to the embodiment shown in Figures 6-7.

[0052] Fig. 10 is a perspective view showing a guide unit 90 to be removed from the main body 2 of the recording device 1 according to the second embodiment of the present disclosure. Figs. 11(a) and 11(b) are cross-sectional views showing the configuration of the guide unit 90 for attaching and removing the guide unit according to the second embodiment of the present disclosure.

[0053] 10 and 11(a), the guide portion 90 has two restricting portions 92, each of which has a first biasing portion 92a, and the housing 91 of the guide portion 90 has two second biasing portions 91c, each of which corresponds to the first biasing portion 92a, with springs 94 disposed between each of the first biasing portions 92a and the corresponding second biasing portion 91c. The elastic force of these springs 94 biases the protruding portions 92b of each restricting portion 92 from the inside of the housing 91 of the guide portion 90 outward in the X direction. This allows the protruding portions 92b of each restricting portion 92 to fit into the first positioning holes 81 formed in the second side surface 26a of the accommodation portion 26 of the main body 2.

[0054] In this embodiment, the guide unit 90 is provided with a moving unit 98, which has an operating unit 99 and is installed in an operating window 91e formed in the housing 91 of the guide unit 90, and the operating unit 99 moves between a first position 93a and a second position 93b of the operating window 91e, causing the moving unit 98 to move along the X direction.

[0055] The moving part 98 has a sliding groove 98a that is an elongated hole formed at an angle with respect to the X direction, and a boss part 96a of the movable part 96 is engaged with this sliding groove 98a. When the operation part 99 moves into the operation window 91e, the sliding groove 98a of the moving part 98 moves in the X direction, and the boss part 96a of the movable part 96 moves along the sliding groove 98a in the Z direction and the opposite direction. This movement causes the protruding part 96b of the movable part 96 to protrude or retract to the third side surface 90b, and can be fitted into (see FIG. 11(a)) or detached from (see FIG. 11(b)) the second positioning hole 83.

[0056] In detail, as shown in Figure 11(a), when the operating part 99 is located at the first position 93a of the operating window 91e, the boss part 96a of the movable part 96 is located at the end 97a close to the third side surface 90b of the sliding groove 98a, and the protrusion part 96b of the movable part 96 protrudes to the third side surface 90b and can fit into the second positioning hole 83.

[0057] Therefore, when the protrusion 92b of the restricting portion 92 fits into the first positioning hole 81 of the accommodating portion 26, the operating portion 99 is moved to the first position 93a of the operation window 91e, and the protrusion 96b of the movable portion 96 can fit into the second positioning hole 83 of the accommodating portion 26. This allows the guide portion 90 to be attached to the main body 2.

[0058] 11(b), when the operation unit 99 is moved to the second position 93b of the operation window 91e along the direction T shown in FIG. 10, the moving unit 98 moves in the X direction relative to the housing 91, and the sliding groove 98a also moves in the X direction. As a result, the boss 96a of the movable unit 96 moves along the sliding groove 98a in the Z direction and in the opposite direction (the V direction shown in FIG. 11(b)). This movement allows the protruding unit 96b of the movable unit 96 to disengage from the second positioning hole 83.

[0059] Furthermore, when the user moves the two operating portions 92c within the operating window 91a along the operating direction H and brings them closer to each other, the protrusion 92b of the restricting portion 92 moves along the operating direction H and comes out of the first positioning hole 81. Therefore, when the protrusion 96b of the movable portion 96 is released into the second positioning hole 83, the protrusion 92b of the restricting portion 92 can be released from the first positioning hole 81 by bringing the operating portions 92c closer to each other. On the other hand, when the protrusion 92b of the restricting portion 92 is released from the first positioning hole 81, the protrusion 96b of the movable portion 96 can also be released into the second positioning hole 83. This allows the guide portion 90 to be removed from the main body 2.

[0060] In this embodiment, an elastic force in the X direction may be applied to the operating unit 99 by an elastic member (not shown). The elastic force urges the operating unit 99 in the X direction and fixes it at the first position 93a and the second position 93b.

[0061] As described above, in the recording device 1 of this embodiment, the main body 2 and the guide unit 90 can be easily attached and detached, and therefore the feed roller 61, the first separation roller 62, and the second separation roller 63 can be easily replaced. In other words, the technology described in this specification can contribute to the realization of a sustainable society, such as a carbon-free / recycling-based society.

[0062] <Embodiment 3> The embodiment shown in Figures 12-13 shows an alternative similar to the embodiment shown in Figures 6-7.

[0063] 12(a) and (b) are cross-sectional views showing the configuration of the guide unit 100 according to the third embodiment of the present disclosure for attaching and detaching the guide unit.

[0064] In this embodiment, the guide unit 100 has one restricting portion 103, and a spring 105 is disposed between the restricting portion 103 and the biasing portion 101d of the housing 101. Due to the elastic force of the spring 105, the protruding portion 103b of the restricting portion 103 protrudes from the inside of the housing 101 of the guide unit 100 along the X direction to a first side surface 102a of the housing 101 and fits into a first positioning hole 81 formed in a second side surface 26a of the main body 2. More specifically, the housing 101 has two opposing first side surfaces 102a, and the protruding portion 103b of the restricting portion 103 protrudes into one first side surface 102a, and a fixing portion 101f is formed on the other first side surface 102a. The fixing portion 101f can fit into a third positioning hole 82 that faces the first positioning hole 81 of the main body 2.

[0065] On the other hand, the restricting portion 103 has a sliding groove 103a which is an elongated hole formed at an angle with respect to the X direction, and a boss portion 107a of the movable portion 107 is engaged with this sliding groove 103a. When the restricting portion 103 is urged and moved toward the outside of the guide portion 100 by the elastic force of the spring 105, the sliding groove 103a moves along the X direction, and the boss portion 107a of the movable portion 107 moves in the Z direction along the sliding groove 103a (see FIG. 11(a)), protruding from the third side surface 102b and being able to fit into the second positioning hole 83.

[0066] As a result, when the fixed portion 101f engages with the third positioning hole 82 opposite to the first positioning hole 81, the movement of the regulating portion 103 causes the protruding portion 103b of the regulating portion 103 to engage with the first positioning hole 81, and in conjunction with this, the protruding portion 107b of the movable portion 107 engages with the second positioning hole 83, and the guide portion 70 is attached to and fixed to the main body 2.

[0067] 12(b), when removing the guide unit 100 from the main body 2, the user inserts his / her finger into the operation portion 103c to move the restriction portion 103 in the H direction, causing the protrusion 103b of the restriction portion 103 to disengage from the first positioning hole 81 and move back to the first side surface 102a of the guide unit 100, and in conjunction with this, the protrusion 107b of the movable portion 107 to disengage from the second positioning hole 83. At that time, the guide unit 100 can be removed from the main body 2 by rotating the guide unit 100 about the fixed portion 101f in the direction indicated by the arrow R in FIG.

[0068] As described above, in the recording device 1 of this embodiment, the main body 2 and the guide unit 100 can be easily attached and detached, and therefore the feed roller 61, the first separation roller 62, and the second separation roller 63 can be easily replaced. In other words, the technology described in this specification can contribute to the realization of a sustainable society, such as a carbon-free / recycling-based society.

[0069] Although the above-described embodiment relates to a configuration in which a separation roller is used as a separation member, the application of the present invention is not limited to this configuration. For example, a separation member in the form of a friction pad can also be used. In the case of a friction pad, multiple recording media are fed and their leading edges abut against the slope of the friction pad. Due to the force relationship acting between the slope and each of the multiple recording media, the topmost recording media is separated and fed.

[0070] In the above-described embodiment, the protrusions (72b, 92b, 103b) integral with the restricting portions move in a direction perpendicular to the short sides of the guide portions to engage with them, but this is not limiting. The protrusions (72b, 92b, 103b) integral with the restricting portions may move in a direction perpendicular to the long sides of the guide portions to engage with them.
