Description

[Technical Field]

[0001] The present disclosure relates to a recording device capable of recording an image on a sheet. [Background technology]

[0002] Patent Document 1 describes a recording device that includes a recording head and a platen that supports the recording medium during recording. The recording device has a path that passes through the recording area and a reversing path that reverses the sheet. The recording area is located between the recording head and the platen. The reversing path is located between a platen support member that supports the platen and a jam processing cover provided on the side of the recording device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-107865 Summary of the Invention [Problem to be solved by the invention]

[0004] When a sheet jams in the reverse path, the user rotates the jam clearing cover around the pivot shaft to expose the reverse path and remove the jammed sheet. When a sheet jams in the path through the recording area, the user opens the jam clearing cover and then rotates the platen support member around the pivot shaft to access the path through the recording area. This means that the user needs to ensure there is space around the jam clearing device.

[0005] The present disclosure has been made in view of the above circumstances, and has as its object to provide a recording device in which space for jam clearance can be easily secured. [Means for solving the problem]

[0006] (1) A recording device according to the present disclosure includes a housing, a first guide member located within the housing and having a first guide surface that defines a first transport path and a second guide surface that defines a second transport path located below the first transport path, and a second guide member located below the first guide member and having a third guide surface that defines the second transport path. The first guide member is movable between a first position where the first guide surface guides a sheet transported along the first transport path and a second position located below the first position, and the second guide member is movable between a third position where the third guide surface guides a sheet transported along the second transport path and a fourth position where the second transport path is open, and the first guide member at the second position is located above the second guide member at the fourth position.

[0007] When a sheet jams in the first transport path, the second guide member can be moved to the fourth position and the first guide member can be moved to the second position. The jammed sheet is exposed downward from the first transport path. Furthermore, when a sheet jams in the second transport path and the second guide member is moved to the fourth position and the first guide member is moved to the second position, the jammed sheet is exposed and hanging down from the second transport path. Furthermore, when a sheet jams in the second transport path and the second guide member is movable to the fourth position and the first guide member is supported by the jammed sheet, the jammed sheet is exposed downward from the second transport path. Therefore, the first and second guide members do not compress the surrounding space, ensuring space for the user to insert their hand into the device. Jam clearance is possible even when the first and second transport paths are inaccessible from above, and the user can easily access the jammed sheet exposed downward, regardless of whether the sheet jams in the first or second transport path.

[0008] (2) The second guide member in the third position supports the first guide member, and the first guide member may move to the second position in conjunction with the second guide member moving from the third position to the fourth position.

[0009] When the first guide member is movable from the first position, it can be supported on the second guide member. When the second guide member is in the fourth position, the first guide member moves downward under its own weight to the second position, exposing the first and second conveying paths downward. This allows the user to clear the jammed sheet without having to worry about where it is.

[0010] (3) The second conveying path may be connected to a downstream position downstream in the conveying direction on the first conveying path and an upstream position upstream in the conveying direction, and the first guide member may move to the first position and the second position by rotating the downstream side of the first conveying path in the conveying direction from the first rotating shaft around a first rotating shaft, and the second guide member may move to the third position and the fourth position by rotating the downstream side of the second conveying path in the conveying direction from the second rotating shaft around a second rotating shaft.

[0011] Because the first guide member and the second guide member open in the same direction, the user can easily find the jammed sheet. Also, a compact device can be realized that does not require a large space around the device.

[0012] (4) At least one of the first guide member or the second guide member may have a convex portion protruding from the second guide surface or the third guide surface, and the first guide member and the second guide member at the third position may abut at the convex portion.

[0013] When the first guide member is released from the first position, the second guide surface of the first guide member can be prevented from colliding with the third guide surface of the second guide member and being damaged.

[0014] (5) The convex portion may be a roller.

[0015] Since the convex portion is rotatable, it is possible to prevent the second guide surface or the third guide surface from being damaged by friction with the convex portion.

[0016] (6) The device may further include a lever that moves to a fifth position where the second guide member is held in the third position and a sixth position where the second guide member can be moved to the fourth position.

[0017] The user can easily use the lever to switch the second guide member from the third position to the fourth position, thereby facilitating jam clearance.

[0018] (7) The device may further include a slider that moves between a seventh position that supports the first guide member at the first position and an eighth position that allows the first guide member to move to the second position.

[0019] The first guide member can be accurately positioned at the first position by moving the slider.

[0020] (8) The slider may have a guide portion that guides the first guide member at the second position to the first position during the process of moving from the eighth position to the seventh position.

[0021] Even when the first guide member is in the second position, it can be easily moved to the first position by moving the slider.

[0022] (9) The device may further include a tray located below the second guide member and capable of being pulled out relative to the housing, and the slider may move from the seventh position to the eighth position in conjunction with the tray being pulled out relative to the housing.

[0023] A user can move the first guide member from the first position to the second position by the simple operation of pulling out the tray.

[0024] (10) The slider may move from the eighth position to the seventh position in conjunction with the tray being pushed into the housing.

[0025] (11) The sheet conveying device may further include a third guide member located upstream of the second guide member in the second conveying path in the conveying direction to partition the second conveying path, a tray located below the second guide member and removable with respect to the housing, and a slider moving in conjunction with the tray. The third guide member may be movable between a ninth position where the third guide member guides a sheet conveyed through the second conveying path and a tenth position where the third guide member enters the second conveying path by rotating a downstream side of the second conveying path in the conveying direction from the third rotation shaft about a third rotation shaft, and the slider may be movable between a seventh position and an eighth position where the third guide member supports the third guide member at the tenth position.

[0026] When the tray is pulled out, the third guide member, which was in the ninth position, enters the second conveying path and moves to the tenth position, making it easier for the user to access the first conveying path and the second conveying path when removing jammed sheets.

[0027] (12) The third guide member may be movable along the third rotation axis, and the recording device may further include a biasing member that biases the third guide member in one direction along the third rotation axis. The third guide member may be separated from the slider by moving in the other direction along the third rotation axis against the biasing member.

[0028] When a downward load is applied to the third guide member in the tenth position, the third guide member moves in the other direction along the third rotation shaft against the biasing force of the biasing member and separates from the slider. This allows the third guide member to move from the tenth position to the ninth position. Therefore, even if a sheet gets jammed in the second conveying path and is caught between the third guide member, the user can remove the jammed sheet simply by pulling it downward.

[0029] (13) The sheet conveying device may further include a reversing roller that conveys the sheet to the second conveying path, and the distance between the first guide member at the first position and the reversing roller may be 297 mm or less.

[0030] The distance between the first guide member and the reversing roller in the first position is set to be equal to or less than the dimensions of an A4-sized sheet. Therefore, when a sheet gets stuck while being nipped by the reversing roller, the leading edge of the sheet hangs down. This allows the user to easily find the jammed sheet and clear the jam.

[0031] (14) The sheet conveying device may further include a reversing roller that conveys the sheet to the second conveying path, and the distance between the first guide member at the first position and the reversing roller may be 127 mm or less.

[0032] Even with the smallest size L sheet, users can easily remove jammed sheets. [Effects of the Invention]

[0033] According to the present disclosure, space for jam clearance work can be easily secured. [Brief explanation of the drawings]

[0035] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings as appropriate. Note that the embodiment described below is merely one example of the present disclosure, and it goes without saying that the embodiment of the present disclosure can be modified as appropriate without departing from the gist of the present disclosure. In the following description, the up-down direction is defined based on the state of FIG. 1 in which the multifunction device 10 is installed so that it can be used, the front-rear direction is defined with the side where the opening 13 is provided as the front side, and the left-right direction is defined when looking at the multifunction device 10 from the front side.

[0036] [Overall structure of the multifunction device 10] As shown in FIG. 1, the multifunction device 10 is generally formed in the shape of a thin rectangular parallelepiped, with a printer unit 11 provided at the bottom. The multifunction device 10 is an example of a recording device. The multifunction device 10 has various functions such as a print function, a facsimile function, and a copy function. As the print function, the multifunction device 10 has a function of recording images on both sides of recording paper 12 using an inkjet method. The recording paper 12 is an example of a sheet. Note that the multifunction device 10 may also record images on the recording paper 12 using a method other than the inkjet method, for example, an electrophotographic method.

[0037] As shown in FIG. 1, the printer unit 11 has a housing 14 with an opening 13 formed in a front surface 75. The housing 14 has a first transport path 65 (described later) and a second transport path 71 (shown in FIG. 2) inside.

As shown in FIG. 2, the printer unit 11 includes a side frame 53 (shown in FIG. 3), a slider 103 (shown in FIG. 4), a feed tray 20, a discharge tray 21, a feed unit 16, a recording unit 24, a pair of transport rollers 59, a pair of discharge rollers 44, a pair of reversing rollers 45, a pair of re-transport rollers 30, a flap 49, a first guide member 54, a rear rotating unit 74, a previous moving body 105, and a first biasing member 17 (shown in FIG. 8A). The feeding tray 20 is an example of a tray, the rear rotating unit 74 is an example of a second guide member, and the front moving body 105 is an example of a third guide member.

[0038] [Side frame 53] As shown in FIG. 3, the side frame 53 is a sheet metal member elongated in the front-rear direction. The side frame 53 rotatably supports a shaft 31 of the conveying roller 60, a shaft 70 of the discharge roller 62, and a shaft 69 of the reversing roller 67, which will be described later. The shaft 31 is an example of a first rotation shaft, and the shaft 69 is an example of a third rotation shaft. The side frame 53 includes a left side frame 114 located on the left side of the housing 14 and a right side frame 115 located on the right side as shown in FIG. 8(A). The left side frame 114 and the right side frame 115 are symmetrical with respect to a plane perpendicular to the left-right direction. In this embodiment, only the left side frame 114 will be described, and a description of the right side frame will be omitted. The left side frame 114 has a vertical portion 220, a horizontal portion 221, and a lever member 218.

[0039] The vertical portion 220 extends in the up-down and front-rear directions. The vertical portion 220 follows the side surface of the housing 14. The vertical portion 220 has a first positioning portion 260 and a second positioning portion 261. The first positioning portion 260 and the second positioning portion 261 are portions where a part of the vertical portion 220 is bent inward by 90 degrees in the left-right direction. The second positioning portion 261 is located rearward of the first positioning portion 260.

[0040] The horizontal portion 221 is located at the bottom of the left side frame 114. The horizontal portion 221 extends in the front-to-rear and left-to-right directions. The horizontal portion 221 extends inward in the left-to-right direction from the lower end of the vertical portion 220. The lever member 218 is located closer to the front of the left side frame 114 in the front-to-rear direction. The lever member 218 is longer in the up-to-down direction than in the front-to-rear direction. The lever member 218 is located on the surface of the vertical portion 220 facing right. The upper end of the lever member 218 is pivotally supported so that it can swing around the left-to-right direction as a rotation center. The lever member 218 hangs down from the left side frame 114, and its lower end extends below the horizontal portion 221.

[0041] The horizontal portion 221 has a notch 225. The notch 225 is a through hole that receives the rotation of the lever member 218. The lever member 218 hangs down from a pivot position within the notch 225. The slider 103 is placed on the horizontal portion 221.

[0042] [Slider 103] The slider 103 is moved to a seventh position and an eighth position forward of the seventh position by inserting and removing the feed tray 20. The slider 103 positions or releases the position of the first guide member 54 at a predetermined position. As shown in FIG. 4A, the slider 103 is a member that is long in the front-rear direction and narrow in the left-right direction, and is a linear cam that moves in the front-rear direction within the housing 14 by inserting and removing the feed tray 20. The slider 103 includes a left slider 116 and a right slider 117 located inside the left side frame 114 and the right side frame 115. The left slider 116 and the right slider 117 are symmetrical with respect to a plane perpendicular to the left-right direction. In this embodiment, the left slider 116 will be described in detail, and a description of the right slider 117 will be omitted. The left slider 116 is located on the horizontal portion 221 shown in FIG. 3. The left slider 116 is slidable on the horizontal portion 221 in the front-to-rear direction to a seventh position and an eighth position.

[0043] As shown in FIGS. 4(A), (B), and (C), the left slider 116 has a first cam surface 255, a second cam surface 125, a third cam surface 126, a pressing portion 216, and a first receiving surface 217. The first cam surface 255 is located toward the front of the left slider 116, approximately in the center of the left slider 116 in the front-to-rear direction. The first cam surface 255 is a horizontal surface facing upward. The first cam surface 255 has a first inclined surface 130 that slopes downward as it extends rearward. The first inclined surface 130 is a surface that is continuous with the rear end of the first cam surface 255. The first inclined surface 130 is an example of a guide portion. Note that in FIGS. 4(A), (B), and (C), the lever member 218 located on the side frame 53 is shown to illustrate the positional relationship between the lever member 218 and the left slider 116.

[0044] As shown in FIG. 4(B), second cam surface 125 is located toward the rear of left slider 116 in the front-to-rear direction. Second cam surface 125 is a horizontal surface facing upward. Second cam surface 125 is located higher than first cam surface 255. Second cam surface 125 has third inclined surface 132 that slopes upward while facing rearward. Third inclined surface 132 is continuous with the rear end of second cam surface 125. Third cam surface 126 is located behind third inclined surface 132.

[0045] Third cam surface 126 is a horizontal surface facing upward. Third cam surface 126 is continuous with the rear end of third inclined surface 132. As shown in FIG. 8(A), third cam surface 126 has second inclined surface 131 that slopes downward while facing right. Second inclined surface 131 is continuous with the right end of third cam surface 126. Third cam surface 126 is located forward and above first cam surface 255. Third cam surface 126 is located above second cam surface 125.

[0046] The pressing portion 216 is located at the front end of the left slider 116. The pressing portion 216 is a surface that faces forward. As shown in FIG. 4(C), it is located towards the front of the left slider 116. The first receiving surface 217 is located in front of the lever member 218. The first receiving surface 217 is a surface that faces rearward. The first receiving surface 217 protrudes downward from the underside of the main body of the slider 103, behind the pressing portion 216 and in front of the lever member 218. The underside of the main body of the slider 103 is the surface that rubs against the upper surface of the horizontal portion 221 of the side frame 53 when the slider 103 moves in the front-rear direction.

[0047] [Feed Tray 20] The feed tray 20 can be inserted into the housing 14 through the opening 13 and can be removed from the housing 14. As shown in FIG. 2 , the feed tray 20 supports recording paper 12. The discharge tray 21 is supported above the feed tray 20. The upper surface of the discharge tray 21 supports recording paper 12 on which an image has been recorded by a recording unit 24, which will be described later. The discharge tray 21 can be inserted into the housing 14 through the opening 13 together with the feed tray 20 and can be removed from the housing 14.

[0048] The feed tray 20 can be manually moved by a user between an inserted position shown in Fig. 2 where it is inserted into the housing 14 and a removed position shown in Fig. 6(A) where it is removed from the housing 14. Plain paper of a size equal to or smaller than A4 and equal to or larger than L size is used as the recording paper 12.

[0049] As shown in FIG. 5, the feed tray 20 has a first abutment surface 235 and a second abutment surface 236. The first abutment surface 235 is located near the center of the feed tray 20 in the front-to-rear direction. The first abutment surface 235 faces rearward. When the feed tray 20 moves from the removal position shown in FIG. 6(A) to the insertion position shown in FIG. 6(B), the feed tray 20 presses the pressing portion 216 of the slider 103 against the first abutment surface 235. When the first abutment surface 235 of the feed tray 20 presses the pressing portion 216 of the slider 103, the slider 103 moves from the eighth position to the seventh position. In this way, the slider 103 moves from the eighth position to the seventh position in conjunction with the insertion of the feed tray 20.

[0050] The second abutment surface 236 is located near the center of the feed tray 20 in the front-to-rear direction and is located rearward of the first abutment surface 235. The second abutment surface 236 faces forward. The second abutment surface 236 is located lower than the first abutment surface 235. When the feed tray 20 moves from the insertion position to the removal position, the second abutment surface 236 abuts against the lever member 218 and causes it to swing, and the lever member 218 abuts against the first receiving surface 217 and presses the slider 103 forward, moving it to the eighth position. In this way, the slider 103 moves from the seventh position to the eighth position in conjunction with the removal of the feed tray 20.

[0051] [Feeding section 16] As shown in FIG. 2, the feed unit 16 is located above the feed tray 20 in the insertion position. The feed unit 16 is supported by a rear pivot unit 74. The feed unit 16 includes a feed roller 25, a feed arm 26, a drive transmission mechanism 27, and a support shaft 28. The feed roller 25 is supported at the tip end of the feed arm 26. The feed arm 26 is rotatable around the support shaft 28 provided at the base end. This allows the feed roller 25 to come into contact with and separate from the recording paper 12 supported by the feed tray 20.

[0052] The feed roller 25 rotates by transmitting the driving force of a transport motor (not shown) through a drive transmission mechanism 27 made up of multiple meshed gears. As a result, of the recording sheets 12 supported on the feed tray 20, the uppermost recording sheet 12 in contact with the feed roller 25 is fed to the first transport path 65.

[0053] [First conveying path 65] 2, in the internal space of the housing 14, a first conveying path 65 extends from the rear end of the feed tray 20. The first conveying path 65 includes a curved portion 33 and a straight portion 34. The curved portion 33 extends upward while curving from the rear end of the feed tray 20, and is connected to the straight portion 34 behind a pair of conveying rollers 59, which will be described later. The straight portion 34 extends in the front-rear direction from the connection position with the curved portion 33 to a pair of reversing rollers 45, which will be described later.

[0054] The curved portion 33 is defined by an outer guide member 18 and an inner guide member 19 that face each other at a predetermined distance. The straight portion 34 is defined at the position where the recording unit 24 is arranged by a nozzle surface 89 of the recording unit 24, a first guide surface 52 positioned opposite the nozzle surface 89, and an upper surface 80 of the flap 49. The recording paper 12 supported on the feed tray 20 is fed to the curved portion 33 by the feed roller 25, and is transported from the curved portion 33 to the straight portion 34 along the transport direction 15.

[0055] [Records 24] The recording unit 24 is located downstream of the conveying rollers 60 and upstream of the discharge rollers 62 in the conveying direction 15. The recording unit 24 includes a carriage 40 and a recording head 38. The carriage 40 is supported by two guide rails (not shown) arranged at a distance in the front-to-rear direction so as to be able to move back and forth in the left-to-right direction. The guide rails are supported at both left and right ends by a left side frame 114 and a right side frame 115. The left side frame 114 is located to the left of the straight portion 34, and the right side frame 115 is located to the right of the straight portion 34.

[0056] The recording head 38 is mounted on the carriage 40. Ink is supplied to the recording head 38 from an ink cartridge (not shown). Nozzles 39 are formed on the underside of the recording head 38. When the carriage 40 moves left and right, the recording head 38 ejects ink droplets from the nozzles 39 toward the first guide member 54. As a result, an image is recorded on the recording paper 12 that has been transported along the straight portion 34 in the transport direction 15 and supported by the first guide member 54.

[0057] [Pair of conveying rollers 59, pair of discharge rollers 44, and pair of reversing rollers 45] 2, a conveying roller pair 59 is arranged upstream of the recording unit 24 in the conveying direction 15 in the straight section 34. A discharge roller pair 44 is arranged downstream of the recording unit 24 in the conveying direction 15 in the straight section 34. A reversing roller pair 45 is arranged downstream of the discharge roller pair 44 in the straight section 34 in the conveying direction 15.

[0058] The conveying roller pair 59 includes a conveying roller 60 arranged below the straight portion 34 and a pinch roller 61 arranged above the straight portion 34 opposite the conveying roller 60. The discharge roller pair 44 includes a discharge roller 62 arranged below the straight portion 34 and a spur roller 63 arranged above the straight portion 34 opposite the discharge roller 62. The reversing roller pair 45 includes a reversing roller 67 arranged below the straight portion 34 and a spur roller 68 arranged above the straight portion 34 opposite the reversing roller 67.

[0059] The pinch roller 61 is biased toward the conveying roller 60 by a coil spring (not shown), so that the pair of conveying rollers 59 can nip the recording paper 12 .

[0060] The conveying roller 60, the discharge roller 62, and the reverse roller 67 rotate forward when a forward driving force from a motor (not shown) is transmitted thereto, and rotate reversely when a reverse driving force is transmitted thereto. The pinch roller 61 rotates in conjunction with the rotation of the conveying roller 60. The spur roller 63 rotates in conjunction with the rotation of the discharge roller 62. The spur roller 68 rotates in conjunction with the rotation of the reverse roller 67.

[0061] When the rollers 60, 62, and 67 rotate forward while the recording paper 12 is nipped between the roller pairs 59, 44, and 45, the nipped recording paper 12 is transported in the transport direction 15. On the other hand, when the rollers 60, 62, and 67 rotate backward, the nipped recording paper 12 is transported in the opposite direction to the transport direction 15.

[0062] [First guide member 54] As shown in FIG. 2, the first guide member 54 is located downstream of the conveying rollers 60 and upstream of the discharge rollers 62 in the conveying direction 15, below the first conveying path 65. The first guide member 54 has a conveying path component 42 and a pressure-receiving member 55. The conveying path component 42 has a first guide surface 52 that defines the first conveying path 65. The first guide member 54 is movable between a first position shown in FIG. 9 where the first guide surface 52 guides the recording paper 12 conveyed through the first conveying path 65, and a second position shown in FIG. 11 that is located downward and away from the first position. When the first guide member 54 is in the first position, the conveying path component 42 and the pressure-receiving member 55 are each positioned.

[0063] The transport path component 42 supports the recording paper 12 transported through the first transport path 65. The transport path component 42 is supported rotatably around the shaft 31 of the transport roller 60. The transport path component 42 has an upstream end in the transport direction 15 supported by the shaft 31. The transport path component 42 has a first guide surface 52 and an abutment portion 265. When the first guide member 54 is in the first position, the distance D1 between the downstream tip 156 of the transport path component 42 in the transport direction 15 and the nip position of the reversing roller pair 45 is set to 127 mm or less in the front-to-rear direction.

[0064] The first guide surface 52 is the surface facing upward of the first guide member 54 in the first position. The first guide surface 52 faces the nozzle surface 89 of the recording unit 24 from below, with the straight portion 34 interposed therebetween.

[0065] The contact portion 265 is located at the rotational tip of the first guide member 54. The contact portion 265 protrudes downward from the second guide surface 50 when positioned at the first position.

[0066] The pressure receiving member 55 has a connecting portion (not shown), and is loosely fitted at the connecting portion to a connected portion (not shown) of the transport path component member 42. Due to this loose fitting, the first guide surface 52 of the first transport path component member 42 is provided so that it can be displaced downward relative to the pressure receiving member 55. The magnitude of this displacement is constrained within a certain range by the loose fitting, so the pressure receiving member 55 rotates integrally with the first transport path component member 42 and the first guide member 54. The pressure receiving member 55 has a second guide surface 50 and a pinch roller 23. The pinch roller 23 is an example of a convex portion.

[0067] The second guide surface 50 is a surface facing downward when the first guide member 54 is in the first position. The second guide surface 50 defines, from above, a second transport path 71 located below the first transport path 65. The pinch roller 23 will be described later.

[0068] When the first guide member 54 moves from the first position to the second position, its downstream end in the conveying direction 15 enters the second conveying path 71. When the first guide member 54 is in the second position, its downstream end in the conveying direction 15 is at the lowest position. The first guide member 54 in the second position is supported by a rear pivot unit 74 in a fourth position, which will be described later. As shown in FIG. 7 , when the slider 103 is in the seventh position, the first guide member 54 is positioned at the first position with the abutment portion 265 supported by the first cam surface 255. When the slider 103 moves from the seventh position to the eighth position, the support of the abutment portion 265 by the first cam surface 255 is released, and the first guide member 54 moves away from the first position.

[0069] [Second conveying path 71] As shown in FIG. 2 , the second conveying path 71 is a path that passes below the straight portion 34 and above the feed roller 25. The second conveying path 71 is located on the opposite side of the straight portion 34 in the up-down direction relative to the discharge roller 62. The second conveying path 71 is located upstream of the reversing roller pair 45 in the conveying direction 15 and downstream of the discharge roller pair 44 in the conveying direction 15, and is a path that branches off from the straight portion 34 at a downstream position 101 that is downstream in the conveying direction. In other words, the second conveying path 71 branches off from the straight portion 34 on the side facing the first guide member 54 in the up-down direction. The second conveying path 71 also merges with the curved portion 33 at an upstream position 102 that is upstream of the conveying roller pair 59 in the conveying direction 15. The second conveying path 71 is defined by a guide surface 77 of the flap 49, an upper surface 113 of the previous moving body 105, a second guide surface 50, and a third guide surface 76, which will be described later. In the second transport path 71, the recording paper 12 is transported in a reverse transport direction 106. The reverse transport direction 106 is the direction from the downstream position 101 to the upstream position 102 in the second transport path 71, and is indicated by a dashed line in FIG.

[0070] [Re-conveying roller pair 30] As shown in FIG. 2 , the re-conveying roller pair 30 is located in the second conveying path 71. The re-conveying roller pair 30 is located behind the discharge roller pair 44 in the front-rear direction. The re-conveying roller pair 30 includes a re-conveying roller 22 arranged below the second conveying path 71 and a pinch roller 23 arranged above the second conveying path 71 to face the re-conveying roller 22. The re-conveying roller 22 is arranged in a rear turning unit 74 (described later). The pinch roller 23 is arranged in the first guide member 54 (described above). The re-conveying roller 22 is driven by a motor (not shown). The pinch roller 23 is supported by the first guide member 54, and a portion of its outer circumferential surface protrudes from the second guide surface 50. The pinch roller 23 rotates in accordance with the rotation of the re-conveying roller 22. The re-conveying roller 22 is supported by the rear turning unit 74, and a portion of its outer circumferential surface protrudes from the third guide surface 76. The re-conveying roller 22 nip the recording paper 12 together with the pinch roller 23. The re-conveying roller 22 rotates forward regardless of whether the driving force of the motor is forward or reverse. When the re-conveying roller 22 rotates forward while the recording paper 12 is nipped between the re-conveying roller pair 30, the nipped recording paper 12 is transported in the reverse transport direction 106.

[0071] [Flap 49] 2, the flap 49 is located between the discharge roller pair 44 and the reversing roller pair 45 on the straight section 34. When the recording paper 12 is transported along the straight section 34 and passes over the upper surface 80, and the reversing roller 67 is rotated in the reverse direction to be transported in the opposite direction, the flap 49 changes its position from a first state indicated by a solid line in FIG. 2 to a second state indicated by a dashed line in FIG. 2, and guides the recording paper 12 to the second transport path 71. When the flap 49 is located in the first state, it guides the recording paper 12 downstream in the transport direction 15 on the first transport path 65.

[0072] In the first state, the flap 49 is rotated counterclockwise in FIG. 2 around the shaft 70 of the discharge roller 62. In the second state, the flap 49 is rotated clockwise in FIG. 2 around the shaft 70. The flap 49 has an upper surface 80 and a guide surface 77. The upper surface 80 is the surface that faces upward when the flap 49 is in the first state. The guide surface 77 is the surface that guides the recording paper 12 to the second transport path 71, and intersects with the second transport path 71 when the flap 49 is in the second state.

[0073] [Rear rotation unit 74] As shown in FIG. 2, the rear turning unit 74 is located below the second conveying path 71 and above the feeding tray 20 in the insertion position. The rear turning unit 74 is supported rotatably about a shaft 43 located below the shaft 31. The shaft 43 is parallel to the shaft 31. The shaft 43 is an example of a second turning shaft. The shaft 43 supports the downstream end of the rear turning unit 74 in the reverse conveying direction 106.

[0074] The rear turning unit 74 is movable between a third position where the third guide surface 76 guides the recording paper 12 being transported in the first transport path 65, and a fourth position shown in Fig. 11 where the second transport path 71 is opened. The third position is the position where the rear turning unit 74 has rotated the most clockwise around the shaft 43 in Fig. 2. The fourth position is the position where the rear turning unit 74 has rotated the most counterclockwise around the shaft 43.

[0075] The rear rotation unit 74 rotatably supports the aforementioned feed arm 26. The rotational driving force of the re-conveyance roller 22 is transmitted to the feed roller 25 by a drive transmission mechanism 27 of the feed arm 26.

[0076] The rear turning unit 74 has the aforementioned re-conveying roller 22, a third guide surface 76, an engaging portion 84, and a second biasing member 85. The engaging portion 84 is an example of a lever. The third guide surface 76 is a surface that faces upward when the rear turning unit 74 is in the third position. When the rear turning unit 74 is in the third position, the third guide surface 76 faces the second guide surface 50 of the first guide member 54 from below, with the second conveying path 71 between them.

[0077] The engaging portion 84 is located at the upstream end of the rear turning unit 74 in the reverse conveying direction 106. The engaging portion 84 is reciprocable between a fifth position where it engages with the housing 14 and a sixth position where it is disengaged from the housing 14. The engaging portion 84 protrudes from the rear turning unit 74 and engages with the housing 14. This engagement positions the rear turning unit 74 at the third position. The second biasing member 85 biases the engaging portion 84 toward the engaged position. The engaging portion 84 is movable to the sixth position against the biasing force of the second biasing member 85 by manual operation by the user.

[0078] [Previously moving body 105] As shown in FIG. 2, the preceding moving body 105 is located upstream of the rear rotating unit 74 in the reverse conveying direction 106. The preceding moving body 105 is supported rotatably around the shaft 69 of the reverse roller 67. The shaft 69 is an example of a third rotating shaft. The preceding moving body 105 is rotatable between a ninth position where it guides the recording paper 12 being conveyed in the second conveying path 71 and a tenth position where it rotates counterclockwise in FIG. 2 from the ninth position so that its downstream end in the reverse conveying direction 106 enters the second conveying path 71. The preceding moving body 105 is supported from below by the discharge tray 21 inserted into the housing 14 and positioned at the ninth position. The preceding moving body 105 is supported from below by the slider 103 positioned at the eighth position and positioned at the tenth position. The ninth position is indicated by a solid line in FIG. 2, and the tenth position is indicated by a dashed line.

[0079] 8(A), the previous moving body 105 has a main body 150, a left support portion 151, a right support portion 152, and a protrusion 153. The main body 150 is a portion that extends downstream in the reverse conveying direction 106 along the second conveying path 71 when the previous moving body 105 is in the ninth position. The main body 150 supports the recording paper 12 being conveyed through the second conveying path 71.

[0080] The left support portion 151 is located on the left side of the front end of the previous moving body 105. The right support portion 152 is located on the right side of the front end of the previous moving body 105. A shaft 69 is inserted through the left support portion 151 and the right support portion 152. A first biasing member 17 is located between the right support portion 152 and the right side frame 115. This biases the previous moving body 105 leftward relative to the right side frame 115. The previous moving body 105, which is biased leftward by the first biasing member 17 and is located in the ninth position, abuts against an abutment piece 154 fixed to the left end of the shaft 69 at the left support portion 151. The previous moving body 105 in the ninth position can move rightward against the biasing force of the first biasing member 17.

[0081] The protrusion 153 protrudes leftward from the left-facing surface of the main body 150. The tip portion 155 of the protrusion 153 is hemispherical. As shown in FIG. 8(A), when the previous moving body 105 is in the ninth position, the protrusion 153 is located above the second cam surface 125. In other words, the protrusion 153 is not supported by the second cam surface 125. When the previous moving body 105 is in the tenth position, the protrusion 153 is located on the third cam surface 126 as shown in FIG. 8(B).

[0082] [Jam Clearance] When a jam occurs, the printer unit 11 performs jam clearance as follows: When a jam occurs, the slider 103 is in the seventh position, the first guide member 54 is in the first position, the rear rotating unit 74 is in the third position, and the front moving body 105 is in the ninth position shown in Figures 2 and 9.

[0083] (1) Remove the feed tray 20 and the discharge tray 21. When the slider 103 slides from the seventh position to the eighth position in conjunction with the feeding tray 20 being pulled out from the insertion position to the removal position, the first guide member 54 is released from the first position. Specifically, as the slider 103 moves from the seventh position to the eighth position, the abutment portion 265 moves from above the first cam surface 255 to the lower end of the first inclined surface 130. This allows the first guide member 54 to move from the first position to the second position under its own weight. At this time, the rear turning unit 74 is maintained in the third position due to the engagement between the engagement portion 84 and the housing 14, as shown in FIG. 10 .

[0084] 2 and 4, when the discharge tray 21 is removed together with the feed tray 20, the slider 103 of the previous moving body 105 moves from the seventh position to the eighth position, and the tip portion 155 comes into contact with the third inclined surface 132 from a position above the second cam surface 125, and then slides on the third inclined surface 132 and moves onto the third cam surface 126. As a result, the previous moving body 105 moves from the ninth position to the tenth position as shown in FIG. 10, and the space below the previous moving body 105 and near the discharge roller 62 becomes wider.

[0085] (2) The rear turning unit 74 is moved from the third position to the fourth position. When a user inserts their hand through the opening 13 and moves the engagement portion 84 of the rear turning unit 74 from the fifth position to the sixth position to disengage the engagement portion 84 from the housing 14, the rear turning unit 74 rotates around the shaft 43 due to its own weight and moves from the third position to the fourth position, as shown in FIG. 11 . If a jam occurs in the first conveyance path 65, the first guide member 54 rotates around the shaft 31 due to its own weight and moves from the first position to the second position, thereby opening the first conveyance path 65. At this time, the first guide member 54 is supported by the rear turning unit 74 in the fourth position. This allows the user to access and remove the recording paper 12 jammed in the first conveyance path 65. At this time, the front moving body 105 is in the tenth position.

[0086] If a jam occurs in the second conveying path 71, the recording paper 12 will be jammed in the second conveying path 71. If the leading edge of the recording paper 12 is located behind the rear guide portion 107, the recording paper 12 will be stretched across the pair of reversing rollers 45 and the rear guide portion 107, as shown in FIG. 12. At this time, the first guide member 54 is supported by the recording paper 12 at a position intermediate between the first and second positions. The first guide member 54 is supported by the recording paper 12 jammed in the second conveying path 71, and the rear rotating unit 74 moves to the fourth position, opening the second conveying path 71. At this time, the front moving body 105 is in the tenth position.

[0087] On the other hand, if a jam occurs in the second conveyance path 71 and the leading edge of the recording paper 12 is positioned forward of the rear guide portion 107 because the recording paper 12 is relatively small, the rear side of the recording paper 12 is nipped by the pair of reversing rollers 45, causing the leading edge to hang down, as shown in FIG. 13. In this case, the first guide member 54 moves from the first position to the second position under its own weight and is supported by the rear rotating unit 74 in the fourth position. This opens the first conveyance path 65 and the second conveyance path 71. At this time, the forward moving body 105 is positioned at the tenth position. The user can easily find and remove the recording paper 12 hanging down from the second conveyance path 71 through the opening 13.

[0088] When recording paper 12 becomes jammed in second conveyance path 71, the user inserts their hand through opening 13 to remove recording paper 12. At this time, previous moving body 105 moves from the ninth position to the tenth position so that space is secured below previous moving body 105. This narrows second conveyance path 71, making it difficult to pull out jammed recording paper 12. In this case, the user can release previous moving body 105 from the tenth position by strongly pulling recording paper 12 downward.

[0089] Specifically, the preceding moving body 105 in the tenth position receives a downward load when the recording paper 12 in the second conveying path 71 is pulled downward. At this time, as shown in Figures 8(B) and (C), the main body 150 moves to the right against the biasing force of the first biasing member 17. As a result, the leading end portion 155 is guided to the second inclined surface 131 and moves downward while sliding along the second inclined surface 131. When the preceding moving body 105 receives a further downward load, as shown in Figure 8(C), the leading end portion 155 leaves the second inclined surface 131 and moves downward while sliding along the surface of the left slider 116 facing right.

[0090] (3) The rear turning unit 74 is returned from the fourth position to the third position. After clearing the jam, the user returns the rear turning unit 74 from the fourth position to the third position, and engages the engaging portion 84 with the housing 14. At this time, the pinch roller 23 is pressed by the re-conveyance roller 22. As a result, the first guide member 54 is pushed up from the second position to a position close to the first position shown in FIG.

[0091] (4) Insert the feed tray 20 and the discharge tray 21. As the feed tray 20 is pushed into the opening 13, the slider 103 slides from the eighth position to the seventh position. Specifically, as the slider 103 moves from the eighth position to the seventh position, the abutment portion 265 slides on the first inclined surface 130 and moves onto the first cam surface 255. As a result, as shown in FIG. 9, the first guide member 54, which has been pushed up by the re-conveyance roller 22, is positioned at the first position. As shown in FIG. 8(A), when the discharge tray 21 and the feed tray 20 are inserted, the previous moving body 105 is supported by the discharge tray 21 at the height of the ninth position, and is urged leftward by the urging force of the first urging member 17, so that the protrusion 153 is positioned above the second cam surface 125.

[0092] [Effects of the embodiment] When recording paper 12 is jammed in the first transport path 65, the rear turning unit 74 can move to the fourth position and the first guide member 54 can move to the second position. At this time, the first guide member 54 overlaps the rear turning unit 74. Therefore, the first guide member 54 and the rear turning unit 74 can be stored compactly without taking up too much space. The jammed recording paper 12 is exposed downward from the first transport path 65. Furthermore, when relatively small-sized recording paper 12, such as L-size paper, is jammed in the second transport path 71, the rear turning unit 74 moves to the fourth position and the first guide member 54 moves to the second position, causing the leading edge of the jammed recording paper 12 to hang down from the second transport path 71. In this case, the user can easily find the recording paper 12 through the opening 13. The first guide member 54 overlaps the rear turning unit 74. Furthermore, when a relatively large size recording sheet 12, such as A4, becomes jammed in the second transport path 71, the recording sheet 12 may become suspended between the pair of reversing rollers 45 and the rear guide portion 107. At this time, the rear pivot unit 74 moves to the fourth position, and the first guide member 54 becomes supported by the jammed recording sheet 12, exposing the jammed recording sheet 12 downward from the second transport path 71. This also ensures space for the user to insert their hand through the opening 13 to clear the jam. Jams can be cleared even when the first transport path 65 and the second transport path 71 are inaccessible from above, and the user can easily access the jammed recording sheet 12 exposed downward, regardless of whether the jam occurs in the first transport path 65 or the second transport path 71.

[0093] When the first guide member 54 is movable from the first position, it can be supported on the rear turning unit 74. When the rear turning unit 74 is in the fourth position, the first guide member 54 moves downward by its own weight to the second position, exposing the first conveying path 65 and the second conveying path 71 downward. This allows the user to insert their hand through the opening 13 and clear the jammed recording paper 12 without having to worry about where it is.

[0094] Because the first guide member 54 and the rear pivot unit 74 open toward the opening 13, the user can easily find the location of the jammed recording paper 12. Also, a compact device can be realized that does not require a large space around the device.

[0095] When the first guide member 54 is released from the first position, the second guide surface 50 of the first guide member 54 can be prevented from colliding with the third guide surface 76 of the rear turning unit 74 and being damaged by wear.

[0096] Since the pinch roller 23 is rotatable, the second guide surface 50 or the third guide surface 76 can be prevented from being damaged or worn due to friction with the pinch roller 23.

[0097] The user can use the engaging portion 84 to easily switch the rear turning unit 74 from the third position to the fourth position, thereby facilitating jam clearance.

[0098] The first guide member 54 can be accurately positioned at the first position by the movement of the slider 103.

[0099] The user can move the first guide member 54 from the first position to the second position by simply pulling out the feed tray 20.

[0100] When the feed tray 20 is pulled out, the previously moving body 105, which was in the ninth position, enters the second conveying path 71 and moves to the tenth position, expanding the space below the previously moving body 105. This makes it easier for the user to access the first conveying path 65 and the second conveying path 71 when removing jammed recording paper 12.

[0101] When a downward load is applied to the previous moving body 105 in the tenth position, the previous moving body 105 moves to the right along the shaft 69 against the biasing force of the first biasing member 17 and separates from the slider 103. This allows the previous moving body 105 to move from the tenth position to the ninth position. Therefore, even if the recording paper 12 becomes jammed in the second conveying path 71 and is pinched between the previous moving body 105, the user can reliably remove the jammed recording paper 12 simply by pulling it downward.

[0102] Even if the recording paper 12 is the smallest size, L size, the user can easily remove the jammed recording paper 12.

[0103] [Variation 1] In the above-described embodiment, when moving the first guide member 54 from the second position to the first position, the rear turning unit 74 is moved from the fourth position to the third position to turn the first guide member 54 from the second position to a position close to the first position, and then the feeding tray 20 is inserted to move the slider 103 from the eighth position to the seventh position, thereby positioning the first guide member 54 at the first position. However, the movement of the first guide member 54 from the second position to the first position is not limited to this.

[0104] The first guide member 54 may move from the second position to the first position in conjunction with the movement of the slider 103 from the eighth position to the seventh position. When the first guide member 54 is in the second position, the abutment portion 265 is located on the first inclined surface 130 of the left slider 116, and slides on the first inclined surface 130 and moves onto the first cam surface 255 in conjunction with the movement of the slider 103 from the eighth position to the seventh position. This positions the first guide member 54 at the first position. The first inclined surface 130 is an example of a guide portion.

[0105] [Effects of Modification Example 1] Even when the first guide member is in the second position, it can be moved to the first position by simply moving the slider, without the need to perform an operation to rotate the rear rotating unit 74.

[0106] [Variation 2] In the above embodiment, the downstream leading end 156 of the transport path forming member 42 in the transport direction 15 when the first guide member 54 is in the first position is separated from the nip position of the reversing roller pair 45 by a distance D1 of 127 mm or less in the front-to-rear direction. However, this is not the only possible configuration. As shown in FIG. 14, the distance D2 between the leading end 156b of the transport path forming member 42b and the nip position of the reversing roller pair 45b may be greater than 127 mm. In addition, in the printer unit 11b, the recording paper 12 used for image recording may be, for example, A3 size, which is larger than A4 size.

[0107] Printer unit 11b is longer in the front-to-rear direction than printer unit 11 of multifunction peripheral 10 according to the embodiment. In other words, straight section 34b and second transport path 71b are longer in the front-to-rear direction than those of printer unit 11, and therefore first guide member 54b, rear turning unit 74b, and feed tray 20b are longer in the front-to-rear direction than first guide member 54, rear turning unit 74, and feed tray 20 of the above-described embodiment. Also, the distance between transport roller pair 59b and discharge roller pair 44b is longer in the front-to-rear direction than the distance between transport roller pair 59b and discharge roller pair 44 of multifunction peripheral 10 according to the above-described embodiment.

[0108] In the printer unit 11b according to the second modified example, the separation distance D2 between the downstream tip 156b of the conveying path component 42b in the conveying direction 15b of the first guide member 54b at the first position and the nip position of the reversing roller pair 45b is set to be greater than 127 mm and equal to or less than 297 mm. When the rear turning unit 74b is at the third position, the re-conveying roller pair 30b is located rearward of the tip 156b of the first guide member 54b at the first position in the front-rear direction.

[0109] [Effects of Modification Example 2] The distance D2 between the leading edge 156b of the transport path component 42b in the first guide member 54b at the first position and the nip position of the reversing roller pair 45b is set to be equal to or less than the dimension of the long side of the A4 size recording paper 12. Therefore, when the recording paper 12 becomes jammed while being nipped by the reversing roller pair 45b, the leading edge of the recording paper 12 hangs down, allowing the user to easily find the jammed recording paper 12 and clear the jam easily.

[0110] [Other variations] In the above-described embodiment, in the first guide member 54, a portion of the outer peripheral surface of the pinch roller 23 protrudes from the second guide surface 50, and in the rear turning unit 74, a portion of the outer peripheral surface of the re-feed roller 22 protrudes from the third guide surface 76. In other words, the pinch roller 23 and the re-feed roller 22 are arranged so that the second guide surface 50 and the third guide surface 76 do not come into contact with each other. However, this configuration is not limited to this. The first guide member 54 may have, for example, a protrusion protruding from the second guide surface 50 to prevent contact with the rear turning unit 74. The protrusion is an example of a convex portion. Alternatively, the first guide member 54 may not have a protrusion, but the third guide surface 76 of the rear turning unit 74 may have a protrusion. A configuration may also be adopted in which protrusions are provided on both the second guide surface 50 and the third guide surface 76 to prevent contact between the first guide member 54 and the rear turning unit 74. The protrusion may be made of an elastic material such as rubber or silicone.

[0111] In the above embodiment, the recording unit 24 is located between the pair of conveying rollers 59 and the pair of discharging rollers 44, but the present invention is not limited to this configuration. The recording unit 24 may be located in any position where it can record an image on the recording paper 12.
