[0028] Hereinafter, the present invention will be briefly described.

[0029] The recording system involved in the first embodiment is characterized in that it comprises: a discharge unit, which is provided in the device body and discharges the medium recorded by the recording unit; a loading unit, which is provided in the device body and can load the medium discharged from the discharge unit; a post-processing unit, which performs post-processing on the medium discharged from the discharge unit in the discharge direction; a relay conveying unit, which is provided in the device body and can convey the medium discharged from the discharge unit to the post-processing unit, and the relay conveying unit has at least one switching component; and a control unit, which controls the discharge of the medium from the discharge unit, and the switching component can switch between a first state and a second state, the first state is a state of constituting a relay path of the medium from the discharge unit to the post-processing unit, and the second state is a state of opening the relay path toward the loading unit, and when the switching component is in the second state, the control unit discharges the medium from the discharge unit to the loading unit.

[0030] According to this aspect, when the post-processing unit is operable, the state of the switching member becomes the first state. The medium recorded by the recording unit is discharged from the discharge unit in the discharge direction and then conveyed to the post-processing unit by the relay conveying unit to be post-processed in the post-processing unit.

[0031] On the other hand, when the post-processing unit cannot operate, the state of the switching member is set to the second state, so that the relay path is opened toward the placement unit. Here, the medium recorded by the recording unit is discharged from the discharge unit in the discharge direction, and then falls from the open part of the relay path to the placement unit and is placed on the placement unit.

[0032] Thus, when the post-processing unit cannot operate, the operation of the recording system can be prevented from being stopped by placing the medium on the placing unit, thereby suppressing a decrease in the productivity of the recording system. In addition, since the medium is discharged using the placing unit provided in the device body, the enlargement of the recording system can be suppressed compared to a configuration in which the medium is discharged to a device other than the device body.

[0033] The recording system involved in the second method is characterized in that, in the first method, the relay conveying section has: an upper path component, constituting an upper portion of the relay path in the device height direction; and a lower path component as the switching component, constituting a lower portion of the relay path in the device height direction, a rotating mechanism portion for conveying the medium by being driven to rotate is provided in the upper path component, and the rotating mechanism portion is not provided in the lower path component.

[0034] According to this aspect, when the state of the lower path member is switched to the first state or the second state, since the rotating mechanism is not provided in the lower path member, the state of the lower path member can be switched more easily than in a configuration in which the rotating mechanism is provided in the lower path member.

[0035] The recording system involved in the third method is characterized in that, in the second method, the relay transport unit has a first rotating shaft extending in the medium width direction intersecting both the discharge direction and the device height direction, the first rotating shaft supports the lower path component to be rotatable, and the lower path component switches between the first state and the second state by rotating around the first rotating shaft.

[0036] According to this aspect, since the lower path member rotates about the first rotation axis, the movable range of the lower path member is smaller than that of a configuration in which the lower path member slides, and thus the space required for switching between the first state and the second state can be reduced.

[0037] A recording system according to a fourth aspect is characterized in that, in the third aspect, a base end portion of the lower path member is rotatably provided on the first rotation axis, and the placement portion is located outside a rotation trajectory of a front end portion of the lower path member opposite to the base end portion.

[0038] According to this embodiment, since the lower path member does not have the loading section in the rotation area, the lower path member can be rotated regardless of the arrangement of the loading section. Thus, since a space for accommodating the medium is ensured between the lower path member and the loading section, when the lower path member is in the second state, the number of sheets of the medium that can be loaded on the loading section can be suppressed from decreasing.

[0039] The recording system involved in the fifth aspect is characterized in that, in the third aspect or the fourth aspect, the loading portion is provided with a protrusion that supports the loaded medium, and the lower path member is provided with a recessed portion into which a part of the protrusion can be inserted when the lower path member is in the second state.

[0040] According to this aspect, in the configuration in which the protrusion is provided on the placement portion, when the lower path member is in the second state, the lower path member and the placement portion can be arranged close to each other by inserting the protrusion into the recessed portion of the lower path member. In other words, the rotation range of the lower path member is not easily restricted by the protrusion. Thus, in the configuration in which the lower path member contacts the placement portion, a larger space can be ensured to be formed on the placement portion.

[0041] The recording system involved in the sixth embodiment is characterized in that in any one of the third to fifth embodiments, the lower path component has a first lower path component and a second lower path component located downstream in the discharge direction relative to the first lower path component, the first lower path component is capable of rotating around the first rotation axis, and the relay transport unit switches the first state and the second state by rotating the first lower path component around the first rotation axis.

[0042] According to this aspect, since the lower path member is divided into the first lower path member and the second lower path member and the first lower path member is rotatable, when poor conveyance of the medium occurs in the middle of the lower path member, the medium can be easily removed from the lower path member.

[0043] The recording system involved in the seventh mode is characterized in that, in the sixth mode, the relay conveying section has a second rotating shaft extending along the width direction of the medium and supporting the second lower path component so as to be rotatable, and the downstream end of the second lower path component in the discharge direction is supported by the second rotating shaft so as to be rotatable.

[0044] According to this method, when the medium remains in the relay conveying unit due to poor conveying, the first lower path member and the second lower path member are rotated to open left and right. In this case, since the range of the opened relay path becomes larger, it is easy to remove the medium from the relay conveying unit.

[0045] The recording system according to the eighth aspect is characterized in that, in the seventh aspect, a detection unit is provided for detecting the open state and the closed state of the second lower path member, and the control unit stops the discharge unit from discharging the medium when the detection unit detects the open state.

[0046] According to this aspect, when the second lower path member is in the open state, the medium is not discharged from the discharge section toward the relay transport section, thereby preventing the medium from falling from the relay path on the way to the post-processing section.

[0047] The recording system involved in the ninth mode is characterized in that, in the second mode, the lower path component has a first lower path component and a second lower path component located downstream in the discharge direction relative to the first lower path component, and the first lower path component is configured to be able to retreat from the relay path, and the lower path component switches from the first state to the second state by retreating from the relay path by the first lower path component.

[0048] According to this method, the lower path component is divided into the first lower path component and the second lower path component. Here, since the first lower path component can be withdrawn from the relay path, when the medium is poorly conveyed in the middle of the relay path, the medium can be easily removed from the lower path component by withdrawing the first lower path component from the relay path.

[0049] The recording system involved in the tenth embodiment is characterized in that, in any one of the sixth to ninth embodiments, a recess is provided at one of the downstream end of the first lower path component in the discharge direction and the upstream end of the second lower path component in the discharge direction, and a convex portion capable of being inserted into the recess is provided at the other of the downstream end of the first lower path component in the discharge direction and the upstream end of the second lower path component in the discharge direction, the recess and the convex portion are capable of relative movement with respect to each other in the height direction of the device, and when the lower path component is in the first state, at least a portion of the convex portion is inserted into the recess.

[0050] According to this embodiment, in the first state in which at least a portion of the convex portion is inserted into the concave portion, the medium transported by the relay transport portion is supported by at least one of the first lower path member and the second lower path member at any position in the discharge direction. Thus, when viewed from the width direction of the medium, compared with a configuration in which the first lower path member and the second lower path member do not overlap in the discharge direction, poor transport of the medium in the relay transport portion can be suppressed.

[0051] Furthermore, since the recessed portion and the convex portion are movable relative to each other in the device height direction, interference between the first lower path member and the second lower path member can be prevented even if either the first lower path member or the second lower path member is retracted from the relay path first.

[0052] The recording system involved in the eleventh embodiment is characterized in that, in any one of the second to tenth embodiments, the discharge portion includes a bending portion, which performs a bending action to deform the medium so that the shape of the medium becomes a waveform when observed from the discharge direction, and the bending portion is capable of switching the presence or absence of the bending action, and the bending portion does not perform the bending action on the medium when the lower path component is in the first state, and performs the bending action on the medium when the lower path component is in the second state.

[0053] According to this aspect, when the lower path member is in the first state, the medium entering the lower path member is not bent, and therefore the relay transport unit can easily transport the medium.

[0054] On the other hand, when the lower path component is in the second state, the bending portion bends the medium entering the lower path component, thereby increasing the rigidity of the medium relative to the force acting in the discharge direction, thereby suppressing the reduction in the loading capacity of the medium caused by curling of the medium on the loading portion.

[0055] The recording system involved in the twelfth embodiment is characterized in that, in any one of the second to eleventh embodiments, the discharge section includes a guide component that guides the medium in the discharge direction, and a straight line extending from the front end of the guide component to the discharge direction is used as an imaginary line, and the lower path component is located below the imaginary line in an orthogonal direction orthogonal to the discharge direction.

[0056] According to this embodiment, when the medium is discharged from the discharge portion, the lower path member is not located above the front end of the guide member in the orthogonal direction, thereby preventing poor transport of the medium caused by the front end of the medium being caught on the lower path member.

[0057] The recording system involved in the thirteenth embodiment is characterized in that, in any one of the first to twelfth embodiments, a receiving portion for receiving the medium is provided at the upstream end of the switching component in the discharge direction, and the receiving portion is convex above the device height direction of the device body in the second state of the switching component, and when the switching component is in the first state, the control portion causes the discharge portion to discharge the medium at a first speed; when the switching component is in the second state, the control portion causes the discharge portion to discharge the medium at a second speed faster than the first speed.

[0058] According to this aspect, when the switching member is in the first state, the medium is discharged to the relay transport unit at the first speed. On the other hand, when the switching member is in the second state, movement of the medium may be restricted by the receiving unit.

[0059] Here, according to this aspect, when the switching member is in the second state, the ejection unit is ejected at a second speed faster than the first speed, so that the accelerated medium passes over the receiving unit and falls toward the placement unit. Thus, compared with a configuration in which the ejection speed of the medium is not changed, defective ejection of the medium can be suppressed.

[0060] The recording system involved in the fourteenth embodiment is characterized in that, in any one of the first to thirteenth embodiments, a determination unit is provided, which determines whether the size of the medium in the discharge direction is a size that can be loaded on the loading unit, and when the determination unit determines that the medium can be loaded, the control unit causes the discharge unit to discharge the medium; when the determination unit determines that the medium cannot be loaded, the control unit causes the discharge unit not to discharge the medium.

[0061] According to this aspect, when the determination unit determines that the size of the medium in the discharge direction is a size that cannot be placed on the placement unit, the medium having a size that cannot be placed on the placement unit will not be discharged to the placement unit. This can prevent the medium from passing over the placement unit at the downstream end in the discharge direction and coming into contact with the post-processing unit and the like and being deformed.

[0062] Implementation Method 1

[0063] Hereinafter, as an example of an embodiment of the present invention, a recording system 1 according to Embodiment 1 will be described in detail.

[0064] like Figure 1 As shown, as an example, the recording system 1 includes a supply unit 2, a printer unit 10, a scanner unit 4, a relay unit 60, and a post-processing unit 6. The recording system 1 is configured as an inkjet recording system that performs recording by ejecting ink Q as an example of liquid onto paper P as an example of a medium. It should be noted that the XYZ coordinate system shown in each figure is an orthogonal coordinate system.

[0065] The X direction is an example of the depth direction of the device when viewed from an operator (not shown) operating the recording system 1, and is a horizontal direction. The X direction is an example of the width direction of the medium intersecting both the conveying direction and the discharge direction of the paper P. The direction toward the inside of the X direction is defined as the +X direction, and the direction toward the outside is defined as the -X direction.

[0066] The Y direction is an example of the width direction of the device when viewed from the operator, and is a horizontal direction. The direction toward the left side of the Y direction is referred to as the +Y direction, and the direction toward the right side is referred to as the -Y direction.

[0067] The Z direction is an example of the height direction of the device and is a vertical direction. The upward direction of the Z direction is defined as the +Z direction, and the downward direction is defined as the -Z direction.

[0068] It should be noted that when each direction is not distinguished between + and -, it is simply described as the X direction, the Y direction, and the Z direction.

[0069] The supply unit 2 stores the paper P. The paper P stored in the supply unit 2 is fed into the printer unit 10 .

[0070] The printer unit 10 is arranged in the -Y direction with respect to the supply unit 2. The printer unit 10 includes a discharge unit 30, a placement unit 40, and a relay unit 60, which will be described later. The printer unit 10 will be described in detail later.

[0071] As an example, the scanner unit 4 is attached to an end portion in the +Z direction of the printer unit 10. The scanner unit 4 reads information of a document (not shown).

[0072] The relay unit 60 constitutes an end portion of the printer unit 10 in the +Z direction, and is located in a position in the -Z direction relative to the scanner unit 4. The relay unit 60 will be described in detail later.

[0073] The post-processing unit 6 is an example of a post-processing unit that performs post-processing on the paper P discharged from the discharge unit 30 in the discharge direction. The post-processing unit 6 is provided at a position in the +Z direction relative to the supply unit 2 and in the -Y direction relative to the printer unit 10. Specifically, the post-processing unit 6 is arranged downstream of the discharge unit 30 in the discharge direction of the paper P. The post-processing unit 6 has a path TB for conveying the paper P fed from the printer unit 10. A binder 7 and a tray 8 are provided at the downstream portion of the path TB.

[0074] As an example of post-processing, the binding machine 7 performs binding processing for binding a predetermined number of sheets of paper P. The bundle of paper P after the binding processing is discharged to the tray 8. It should be noted that the post-processing of the paper P includes: punching processing for punching holes in the paper P, folding processing for folding a bundle of paper P, cutting processing for cutting the paper P, folding processing for folding the paper P, binding processing for stapling the paper P, etc.

[0075] As an example, the printer unit 10 includes a device body 12, a paper storage section 14 for storing paper P, a paper conveying section 16 for conveying paper P, a recording section 20 for recording on paper P, a discharge section 30 for discharging paper P, a placement section 40 for placing discharged paper P, and a relay unit 60 for conveying paper P. In the following description, as an example of a discharge direction, the discharge direction in which the discharge section 30 discharges the paper P is referred to as an E direction, which is indicated by an arrow E.

[0076] like Figure 2 As shown, the printer unit 10 further includes a control unit 50, a folding unit 34, a paper sensor 55, an opening and closing sensor 56, an interlock circuit 58, and a rotating mechanism unit 80. The folding unit 34, the opening and closing sensor 56, the interlock circuit 58, and the rotating mechanism unit 80 will be described later.

[0077] The control unit 50 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, a RAM (Random Access Memory) 53, a memory (not shown), and a determination unit 54. The control unit 50 controls the conveyance operation of the paper P in the printer unit 10, the discharge operation of the paper P from the discharge unit 30 described later, and the operation of each unit including the recording unit 20 and the relay unit 60.

[0078] As an example, the paper sensor 55 is located in a conveying path T ( Figure 1 ) is provided upstream of the recording unit 20. As an example, the paper sensor 55 is an optical sensor capable of measuring the time during which light is blocked by the paper P. Time information measured by the paper sensor 55 is sent to the determination unit 54.

[0079] The determination unit 54 recognizes the size of the paper P being transported based on the time information sent from the paper sensor 55 and the information of the transport speed of the paper P preset in the determination unit 54. Then, the determination unit 54 compares the preset speed of the placing unit 40 ( Figure 1 ) and the size of the paper P being transported to determine whether the size of the paper P in the E direction is a size that can be placed on the placement section 40 described later.

[0080] Note that, when the size of paper in the E direction that can be placed on the placement portion 40 is different between the first state and the second state of the first lower path member 92 described later, the above determination criterion may be switched according to the state of the first lower path member 92 .

[0081] like Figure 1 As shown, the device body 12 is composed of a frame 12A that forms the outer contour of the printer unit 10 and a frame member not shown. A vertical wall 13 ( Figure 3 ).

[0082] The vertical wall 13 is a wall portion that stands upright in the +Z direction at the end portion in the +Y direction of the placement portion 40. An opening 13A ( Figure 5 ).

[0083] The paper storage unit 14 is provided at a position closer to the −Z direction than the center in the Z direction of the apparatus main body 12. As an example, the paper storage unit 14 includes four paper cassettes 15.

[0084] The paper conveying unit 16 is provided in the apparatus body 12. As an example, the paper conveying unit 16 includes a pickup roller 17, a paper feed roller 18, a separation roller 19, a plurality of conveying rollers 21, a belt unit 22, and a motor (not shown).

[0085] As an example, the transport path T includes a paper feeding path T1, a straight path T2, a discharge path T3, a return path T4, and a reversing path T5. A portion of the reversing path T5 is provided in a position in the +Z direction relative to the recording unit 20 described later and in the -Z direction relative to the placement unit 40. In addition, a portion of the reversing path T5 can be opened by rotating the placement unit 40.

[0086] The paper P in the paper storage unit 14 is fed to the transport path T by the rotation of the pickup roller 17 and the paper feed roller 18, and is separated one by one by the separation roller 19. The plurality of transport rollers 21 and the belt unit 22 transport the separated paper P toward the recording unit 20 in the transport direction, and then transport the recorded paper P toward the discharge unit 30. Each roller is driven to rotate by a motor (not shown).

[0087] As an example, the recording unit 20 is configured as a line head facing the belt unit 22. The recording unit 20 has a plurality of nozzles (not shown) arranged corresponding to the entire area in the X direction of the paper P. The recording unit 20 performs recording on the paper P by ejecting ink Q supplied from an ink tank (not shown) toward the paper P from the plurality of nozzles.

[0088] The discharge unit 30 is provided in the apparatus body 12. The discharge unit 30 discharges the paper P recorded by the recording unit 20 to the relay unit 60 or the loading unit 40 described later. As an example, the discharge unit 30 includes a discharge roller pair 31, a discharge guide 32, and a bending unit 34 ( Figure 4 ).

[0089] like Figure 4 As shown in FIG. 5 , the discharge roller pair 31 is arranged to be rotatable around a rotation axis along the X direction. The discharge roller pair 31 includes a driving roller 31A that is rotated by a motor (not shown) and a driven roller 31B that rotates as the driving roller 31A rotates. It should be noted that the discharge roller pair 31 is indicated by a dotted line. Based on the determination unit 54 ( Figure 2 ) in the paper size determination result, the control unit 50 ( Figure 2 ) determines whether the driving roller 31A rotates.

[0090] Specifically, when the determination unit 54 determines that the paper P can be placed on the placement unit 40 ( Figure 1 ), the control unit 50 causes the discharge unit 30 to discharge the paper P. In addition, when the determination unit 54 determines that the paper P cannot be placed on the placement unit 40, the control unit 50 causes the discharge unit 30 not to discharge the paper P. When the discharge unit 30 does not discharge the paper P, the control unit 50 causes the conveying path T( Figure 1 ) stops conveying the paper P.

[0091] When the lower path member 86 described later is in the first state, the control unit 50 causes the discharge unit 30 to discharge the paper P at a first speed V1 (mm / sec). In addition, when the lower path member 86 is in the second state described later, the control unit 50 causes the discharge unit 30 to discharge the paper P at a second speed V2 (mm / sec). The second speed V2 is faster than the first speed V1. It should be noted that the illustration of the first speed V1 and the second speed V2 is omitted. When the lower path member 86 is in the second state, the control unit 50 causes the paper P to be discharged from the discharge unit 30 to the loading unit 40.

[0092] The discharge guide 32 is provided downstream of the nip position of the discharge roller pair 31 in the E direction of the paper P. As an example, the discharge guide 32 has a lower wall portion 32A and an upper wall portion 32B. The discharge guide 32 is an example of a guide member that guides the paper P in the E direction.

[0093] The length of the lower wall 32A in the X direction is longer than the length of the paper P in the X direction. The lower wall 32A is tilted so that the end in the -Y direction is closer to the +Z direction than the end in the +Y direction. The lower wall 32A supports the paper P discharged from the discharge roller pair 31 and guides it to the relay unit 60 described later.

[0094] The upper wall portion 32B faces the lower wall portion 32A. When the leading end of the paper P discharged from the discharge roller pair 31 rises, the upper wall portion 32B contacts the paper P to restrict the rise.

[0095] The folding unit 34 is configured to be switchable between the folding operation and the non-folding operation of the paper P. The folding operation of the paper P is an operation of deforming the paper P so that the shape of the paper P becomes a wave when the paper P is viewed from the E direction.

[0096] The corrugated shape is not limited to a shape in which hills and valleys are alternately arranged in the paper width direction, but includes a shape having at least one hill or a shape having at least one valley.

[0097] When an external force in the E direction is applied to the bent paper P, the paper P becomes corrugated, thereby increasing the rigidity of the paper P against the external force, and the paper P is not easily deformed. Figure 4 Only one bend 34 is shown.

[0098] As an example, the bending section 34 includes a holder 35, a pressing roller 36, and a holder driving section 37. In addition, a rotating shaft 38 is provided on a frame (not shown) of the device body 12. The rotating shaft 38 extends in the X direction.

[0099] The holder 35 is located at a position aligned with the driving roller 31A in the X direction. The holder 35 is a member that is long in one direction. The base end of the holder 35 is connected to the rotating shaft 38. Thus, the front end opposite to the base end of the holder 35 can rotate around the rotating shaft 38.

[0100] The pressing roller 36 is arranged with the X direction as the axial direction, and is rotatably supported by the front end of the holder 35. The pressing roller 36 is composed of a plurality of disc-shaped members arranged at intervals in the X direction. The pressing roller 36 bends the paper P by contacting the paper P discharged from the clamping portion of the discharge roller pair 31 from a position in the +Z direction to a position in the -Z direction.

[0101] As an example, the holder driving unit 37 is configured to include: a spring (not shown) that applies a pressing force including a component in the -Z direction to the holder 35; and a motor 37A that rotates the holder 35 in a direction that resists the pressing force. The holder driving unit 37 is driven by the control unit 50 ( Figure 2 ) control. The motor 37A rotates the rotating shaft 38 by being energized. It should be noted that the motor 37A releases the holding of the rotating shaft 38 in the non-energized state.

[0102] When the lower path member 86 described later is in the first state, the bending unit 34 drives the holder driving unit 37 to retract the holder 35 and the pressing roller 36 from the discharge path T3 of the paper P. That is, when the lower path member 86 is in the first state described later, the bending unit 34 does not perform a bending operation on the discharged paper P.

[0103] In addition, when the lower path member 86 is in the second state described later, the bending portion 34 makes the holder driving portion 37 in the non-energized state, and the holder 35 and the pressing roller 36 protrude toward the discharge path T3 of the paper P. That is, when the lower path member 86 is in the second state, the bending portion 34 performs a bending operation on the paper P. The operation of the bending portion 34 is controlled by the control portion 50.

[0104] like Figure 1 As shown, as an example, the placement unit 40 is provided in the apparatus body 12 at a position in the +Z direction relative to the recording unit 20 and the reversing path T5. The placement unit 40 is a portion where at least one sheet of paper P discharged from the discharge unit 30 can be placed.

[0105] As an example, the placement portion 40 is configured to include a shaft portion 42, a first bottom portion 44, a second bottom portion 46, and a release lever 48 ( Figure 3 ).

[0106] The shaft portion 42 extends in the X direction. Both ends of the shaft portion 42 in the X direction are supported by a frame member (not shown) of the device body 12 .

[0107] The first bottom portion 44 is formed in a plate shape. The width of the first bottom portion 44 in the X direction is wider than the width of the paper P in the X direction. The base end portion of the first bottom portion 44 in the +Y direction is connected to the shaft portion 42 in a rotatable manner. Thus, the front end portion of the first bottom portion 44 in the -Y direction can rotate around the shaft portion 42. The first bottom portion 44 constitutes the upper portion of the reversing path T5. In this way, the first bottom portion 44 can open and close the reversing path T5 by rotating.

[0108] When the reversing path T5 is closed, the first bottom portion 44 is arranged in an inclined state with the front end in the -Y direction closer to the +Z direction than the base end in the +Y direction. The end surface of the first bottom portion 44 in the +Z direction is defined as an upper surface 44A.

[0109] The second bottom portion 46 is located in the -Y direction relative to the first bottom portion 44. The second bottom portion 46 is fixed to a frame member (not shown) of the device body 12. The end surface of the second bottom portion 46 in the +Z direction is set as the upper surface 46A. The upper surface 46A is inclined in such a manner that the end in the -Y direction is closer to the +Z direction than the end in the +Y direction. In addition, the upper surface 46A constitutes the loading surface 43 together with the upper surface 44A in the closed state of the first bottom portion 44. Paper P is loaded on the loading surface 43.

[0110] Release lever 48 ( Figure 3 ) is provided at the end portion in the -X direction of the first bottom portion 44. The release lever 48 has a function of locking the first bottom portion 44 to a frame member not shown. In addition, the release lever 48 releases the lock of the first bottom portion 44 by being operated.

[0111] like Figure 5 As shown in the figure, when the mounting portion 40 is viewed from the X direction, the inclined direction in which the mounting surface 43 extends is set as the A direction. In the A direction, the direction having a component in the +Z direction is set as the +A direction, and the direction having a component in the -Z direction is set as the -A direction. In addition, the direction orthogonal to the A direction is set as the B direction. In the B direction, the direction having a component in the +Z direction is set as the +B direction, and the direction having a component in the -Z direction is set as the -B direction.

[0112] like Figure 3 As shown, the relay unit 60 is provided at a position in the -Y direction and the +Z direction relative to the central portion of the device body 12. The relay unit 60 is located in the +Z direction relative to the placement portion 40 and is opposite to the placement portion 40. In addition, when viewed from the position in the +Z direction toward the -Z direction, the relay unit 60 covers the placement portion 40. It should be noted that the device body 12 is provided with a cover member 24.

[0113] The cover member 24 covers the ends of the relay unit 60 in the -X direction and the -Y direction. The delivery port 23 is formed at the end of the cover member 24 in the -Y direction. The delivery port 23 is a port for delivering the paper P to the post-processing unit 6 ( Figure 1 ) is sent out through the opening.

[0114] like Figure 5 As shown in FIG. 1 , the relay unit 60 is an example of a relay conveying unit that can convey the paper P discharged from the discharge unit 30 to the post-processing unit 6. In addition, as an example, the relay unit 60 includes a main frame 62 ( Figure 6 ), the upper path member 72, the rotating mechanism 80, the lower path member 86, the first rotating shaft 87, the second rotating shaft 88, the spring member 125 and the spring member 127 ( Fig.10 ). It should be noted that, in the transport path T of the paper P, the path between the discharge unit 30 and the post-processing unit 6 is referred to as the relay path TA. In other words, the transport path T includes the relay path TA.

[0115] like Figure 6 As shown, as an example, the main frame 62 is configured to include a front frame 63, a rear frame 64, a left frame 65, and a right frame 66.

[0116] The front frame 63 is composed of a side plate having a predetermined thickness in the X direction. The front frame 63 is located in the -X direction relative to the relay path TA. The front frame 63 has a lateral portion 63A extending in the Y direction, a longitudinal portion 63B extending from the end of the lateral portion 63A in the -Y direction to the -Z direction, and an inclined portion 63C extending from the end of the lateral portion 63A in the +Y direction to a position in the +Y direction and the -Z direction.

[0117] The lateral portion 63A is provided with a gear portion 85 to be described later. The longitudinal portion 63B is provided with a drive motor 83 to be described later. The longitudinal portion 63B rotatably supports the end portion in the -X direction of the second rotating shaft 88 to be described later. The inclined portion 63C rotatably supports the end portion in the -X direction of the first rotating shaft 87 to be described later.

[0118] A first notch 63D and a second notch 63E are formed at the end of the lateral portion 63A in the -Z direction. The first notch 63D can accommodate a portion of a first operating portion 108 described later. The second notch 63E can accommodate a portion of a second operating portion 126 described later.

[0119] The lateral portion 63A is provided with a contacted portion (not shown) that contacts the magnets 91 and 123 described later. The first lower path member 92 described later is maintained in the first state by the contact between the magnet 91 and the contacted portion. In addition, the second lower path member 112 is maintained in the closed state by the contact between the magnet 123 and the contacted portion.

[0120] The rear frame 64 is located in the +X direction relative to the front frame 63. The rear frame 64 has the same size and shape as the front frame 63. The rear frame 64 rotatably supports the +X direction end of the first rotating shaft 87 and the +X direction end of the second rotating shaft 88 described later.

[0121] The left frame 65 connects the end of the front frame 63 in the +Y direction and the end of the rear frame 64 in the +Y direction in the X direction. The left frame 65 is composed of a plurality of plate materials, and covers a part of the relay path TA.

[0122] The right frame 66 connects the end of the front frame 63 in the -Y direction and the end of the rear frame 64 in the -Y direction in the X direction. The right frame 66 is composed of a plurality of plates and is located in the -Z direction relative to the relay path TA. The right frame 66 is formed with an outlet 68 for discharging the paper P. The outlet 68 includes a discharge port 23 ( Figure 3 )middle.

[0123] like Figure 5 As shown, the upper path member 72 is arranged at the upper part in the +Z direction relative to the center of the relay path TA in the Z direction. A rotating mechanism 80 described later is provided on the upper path member 72. As an example, the upper path member 72 has an inclined wall 74 and an upper wall 76.

[0124] The inclined wall 74 is located downstream of the discharge guide 32 in the E direction. The inclined wall 74 is inclined so that the end in the -Y direction is closer to the +Z direction than the end in the +Y direction. In other words, the inclined wall 74 extends obliquely upward relative to the discharge guide 32.

[0125] The upper wall 76 extends in the -Y direction from the end portion in the -Y direction of the inclined wall 74. As an example, the upper wall 76 is connected to the inclined wall 74. The portion where the upper wall 76 and the inclined wall 74 are connected is curved.

[0126] The rotating mechanism 80 is driven to rotate to convey the paper P from the discharge unit 30 to the post-processing unit 6. As an example, the rotating mechanism 80 includes a plurality of upper rollers 82, a drive motor 83 ( Figure 6 ), a plurality of toothed rollers 84 and a gear portion 85 ( Figure 6 ).

[0127] The plurality of upper rollers 82 are arranged at intervals in the E direction in the upper path member 72. In addition, a plurality of the plurality of upper rollers 82 are also arranged in the X direction. The plurality of upper rollers 82 rotate around a rotation axis along the X direction. Parts of the outer peripheral surfaces of the plurality of upper rollers 82 are exposed from the upper path member 72 to the relay path TA and can contact the paper P.

[0128] The plurality of toothed rollers 84 are provided at intervals in the E direction at positions different from the plurality of upper rollers 82 in the upper path member 72. The plurality of toothed rollers 84 rotate around a rotation axis along the X direction. A plurality of teeth (not shown) are provided on the outer periphery of the plurality of toothed rollers 84. The outer diameter of the toothed rollers 84 is smaller than the outer diameter of the upper rollers 82. The plurality of toothed rollers 84 rotate by contact with the paper P being transported.

[0129] like Figure 6 As shown, the driving motor 83 is driven by the control unit 50 ( Figure 2 ) control action, thereby causing multiple upper rollers 82 to rotate or stop.

[0130] The gear portion 85 has a plurality of drive gears 85A and a plurality of transmission gears 85B. The drive gear 85A is attached to the end portion in the -X direction of the upper roller 82. The transmission gear 85B transmits the driving force from the drive motor 83 to the drive gear 85A.

[0131] like Figure 5 As shown, the lower path member 86 is configured to be closer to the lower part in the -Z direction than the center in the Z direction of the relay path TA. The lower path member 86 is an example of a switching member. The lower path member 86 is configured to be able to switch between a first state, which is a state of configuring the relay path TA of the paper P from the discharge section 30 to the post-processing unit 6, and a second state, which is a state of opening the relay path TA toward the placement section 40. As an example, the lower path member 86 is not provided with the drive motor 83 and the gear section 85 as the rotating mechanism section 80.

[0132] As an example, the lower path member 86 includes a first lower path member 92 and a second lower path member 112. The width of each of the first lower path member 92 and the second lower path member 112 in the X direction is wider than the width of the paper P in the X direction.

[0133] The first lower path member 92 is rotatable about a first rotating shaft 87 described below.

[0134] The second lower path member 112 is rotatable about a second rotation shaft 88 described below.

[0135] Here, the first lower path member 92 of the lower path member 86 switches between the first state and the second state by rotating about the first rotation axis 87. It should be noted that in this embodiment, as an example, the first state and the second state are not defined for the rotation of the second lower path member 112.

[0136] Figure 7 The first lower path member 92 is shown in a state where it is arranged along the XY plane.

[0137] When viewed from the Z direction, the first lower path member 92 is formed into a rectangular shape in which the dimension in the X direction is longer than the dimension in the Y direction. The first lower path member 92 has a predetermined height in the Z direction. Specifically, the first lower path member 92 includes an upper wall 93, a first inclined wall 95, a second inclined wall 96, a curved wall 98, a front end portion 102, two side walls 105, a protrusion 106, and a first operating portion 108. It should be noted that the end portion in the +Y direction of the first lower path member 92 is set as a base end portion 101.

[0138] The upper wall 93 is formed in a plate shape having a predetermined thickness in the Z direction. A plurality of ribs 93A are provided on the upper wall 93 to protrude from the upper wall 93 in the +Z direction. In addition, a plurality of roller receiving portions 93B are provided on the upper wall 93 to rotatably receive rollers (not shown). In addition, a contact portion 93C is provided at the end of the upper wall 93 in the +X direction to stand upright from the upper wall 93 in the +Z direction.

[0139] When the lower path member 86 is in the first state described later, the abutment portion 93C is in contact with the main frame 62 ( Figure 6 ) part to ensure a space for a relay path TA between the upper wall 93 and the main frame 62. In addition, a magnet 91 is installed at a portion of the end of the upper wall 93 in the -X direction that is closer to the -Y direction than the center in the Y direction.

[0140] The first inclined wall 95 extends obliquely downward from the end portion of the upper wall 93 in the +Y direction toward a position in the +Y direction and the −Z direction.

[0141] The second inclined wall 96 extends obliquely downward from the +Y direction end of the first inclined wall 95 toward a position in the +Y direction and the -Z direction. The angle formed by the second inclined wall 96 with respect to the Y direction is larger than the angle formed by the first inclined wall 95 with respect to the Y direction.

[0142] The curved wall 98 curves from the end portion of the upper wall 93 in the −Y direction toward a position in the −Y direction and the −Z direction.

[0143] The front end portion 102 has a vertical wall 102A, a plurality of convex portions 103, and a plurality of concave portions 104. In other words, the plurality of convex portions 103 and the plurality of concave portions 104 are provided at the downstream end of the first lower path member 92 in the E direction.

[0144] The vertical wall 102A extends from the end portion of the curved wall 98 in the -Y direction toward the -Z direction.

[0145] The plurality of convex portions 103 protrude obliquely downward from the vertical wall 102A in the -Y direction and the -Z direction. The plurality of convex portions 103 are arranged at intervals in the X direction. Figure 8 ), the protrusion 103 has a size that allows it to be inserted along the Z direction.

[0146] The convex portion 103 has a parallelogram shape when viewed from the X direction. A side wall 103A is provided at an end portion in the -Y direction of the convex portion 103. Side walls 103B are provided at both ends of the convex portion 103 in the X direction.

[0147] The plurality of recesses 104 are arranged at intervals in the X direction. The recess 104 is composed of a vertical wall 102A and two side walls 103B. Figure 8 ) can be inserted into the recess 104 along the Z direction.

[0148] The two side walls 105 extend from both ends of the upper wall 93 , the first inclined wall 95 , and the second inclined wall 96 in the X direction toward the −Z direction.

[0149] The protrusion 106 is provided at the base end portion 101. The protrusion 106 protrudes outward from the side wall 105 in the X direction. The protrusion 106 supports the first rotating shaft 87 ( Figure 5 ).

[0150] The first operating portion 108 extends in the -X direction from the peripheral portion of the portion where the magnet 91 is provided on the side wall 105 in the -X direction. The first operating portion 108 is held and rotated by an operator (not shown). The distance from the first operating portion 108 to the front end portion 102 is shorter than the distance from the first operating portion 108 to the protrusion 106.

[0151] like Fig. 9 As shown in the figure, as an example, the receiving portion 94 is formed by the first inclined wall 95 and the second inclined wall 96. That is, the receiving portion 94 for receiving the paper P is provided at the upstream end of the first lower path member 92 in the E direction. In the second state of the first lower path member 92, the receiving portion 94 is convex in the +Z direction. Here, a straight line extending from the front end of the lower wall portion 32A in the E direction to the +E direction is set as an imaginary line K. The imaginary line K is indicated by a single-dot chain line K.

[0152] The first lower path member 92 is located below the imaginary line K in the orthogonal direction that is orthogonal to the E direction.

[0153] exist Fig. 9 In FIG. 1 , the first lower path member 92 in the first state is indicated by a two-dot chain line, and the first lower path member 92 in the second state is indicated by a solid line.

[0154] Figure 8 The second lower path member 112 is shown in a state where it is arranged along the XY plane.

[0155] When viewed from the Z direction, the second lower path member 112 is formed into a rectangular shape whose dimension in the X direction is longer than that in the Y direction. The second lower path member 112 has a predetermined height in the Z direction. Specifically, the second lower path member 112 includes an upper wall 113, a vertical wall 114, an inclined wall 116, a front end portion 118, two side walls 122, a protrusion 124, a second operating portion 126, and a detected portion 128. It should be noted that the end portion in the -Y direction of the second lower path member 112 is set as the base end portion 111.

[0156] The upper wall 113 is formed in a plate shape having a predetermined thickness in the Z direction. A plurality of ribs 113A are provided on the upper wall 113 so as to protrude from the upper wall 113 in the +Z direction. In addition, a plurality of roller receiving portions 113B are provided on the upper wall 113 so as to rotatably receive a plurality of rollers (not shown). In addition, a contact portion 113C is provided at the end portion of the upper wall 113 in the +X direction so as to stand upright from the upper wall 113 in the +Z direction.

[0157] The abutment portion 113C is formed by contacting with the main frame 62 ( Figure 6 ) to ensure a space for a relay path TA between the upper wall 113 and the main frame 62. In addition, a magnet 123 is installed at a portion of the upper wall 113 in the -X direction that is closer to the +Y direction than the center in the Y direction.

[0158] The vertical wall 114 extends from the end portion of the upper wall 113 in the -Y direction toward the -Z direction.

[0159] The inclined wall 116 extends obliquely downward from the end portion of the upper wall 113 in the +Y direction toward a position in the +Y direction and the −Z direction.

[0160] The front end portion 118 has the inclined wall 116, a plurality of convex portions 119, and a plurality of concave portions 121. In other words, the plurality of convex portions 119 and the plurality of concave portions 121 are provided at the upstream end of the second lower path member 112 in the E direction.

[0161] A plurality of convex portions 119 protrude from the inclined wall 116 in the +Y direction. The plurality of convex portions 119 are arranged at intervals in the X direction. Figure 7 ), the protrusion 119 has a size that allows it to be inserted along the Z direction.

[0162] The convex portion 119 has an upper surface 119A located at the end in the +Z direction and an inclined surface 119B extending obliquely downward from the end in the +Y direction of the upper surface 119A. Side walls 119C are provided at both ends in the X direction of the convex portion 119.

[0163] The plurality of recesses 121 are arranged at intervals in the X direction. The recess 121 is a portion formed by the two side walls 119C and the inclined wall 116. The convex portion 103 ( Figure 7 ) can be inserted into the recess 121 along the Z direction.

[0164] The two side walls 122 extend toward the −Z direction from both ends of the upper wall 113 , the vertical wall 114 , and the inclined wall 116 in the X direction.

[0165] The protrusion 124 is provided at the base end portion 111. The protrusion 124 protrudes outward from the side wall 122 in the X direction. The protrusion 124 supports the second rotation shaft 88 ( Figure 5 ).

[0166] The second operating portion 126 extends in the -X direction from the peripheral portion of the portion where the magnet 123 is provided on the side wall 122 in the -X direction. The second operating portion 126 is held and operated by an operator (not shown). The distance from the second operating portion 126 to the front end portion 118 is shorter than the distance from the second operating portion 126 to the protrusion 124.

[0167] The detected portion 128 is a portion extending from the end in the +Y direction to the +X direction on the side wall 122 in the +X direction. As an example, the detected portion 128 is formed in a prism shape. When the second lower path component 112 is arranged along the XY plane, in other words, when the lower path component 86 is in the first state, the detected portion 128 blocks the opening and closing sensor 56 ( Figure 2 In addition, when the second lower path member 112 is in a state of opening the relay path TA, the detected portion 128 does not block the light of the opening and closing sensor 56.

[0168] like Figure 5 As shown, the first rotating shaft 87 is located at the position of the -Y direction and the -Z direction relative to the center of the E direction of the discharge guide 32. The first rotating shaft 87 is supported by a frame member (not shown) of the device body 12 so as to be rotatable. The first rotating shaft 87 extends in the X direction intersecting both the E direction and the Z direction. The first rotating shaft 87 is composed of a cylindrical member. The first rotating shaft 87 supports the first lower path member 92 so as to be rotatable.

[0169] Specifically, the base end portion 101 of the first lower path member 92 is attached to the first rotating shaft 87. In addition, the first lower path member 92 switches between the first state and the second state by rotating around the first rotating shaft 87.

[0170] The second lower path member 112 is located downstream in the E direction relative to the first lower path member 92 .

[0171] The second rotating shaft 88 is located in the -Z direction relative to the upper wall 76. The second rotating shaft 88 is rotatably supported by a frame member (not shown) of the device body 12. The second rotating shaft 88 is composed of a cylindrical member extending in the X direction. The second rotating shaft 88 rotatably supports the second lower path member 112.

[0172] Specifically, the base end portion 111 of the second lower path member 112 in the -Y direction is attached to the second rotating shaft 88. In other words, the downstream end portion of the second lower path member 112 in the E direction is rotatably supported by the second rotating shaft 88. In addition, the second lower path member 112 is rotated around the second rotating shaft 88 to switch between a closed state in which the relay path TA is formed and an open state in which the relay path TA is opened.

[0173] In the first state of the lower path member 86, the first lower path member 92 forms the upstream portion of the relay path TA by facing the inclined wall 74. The first lower path member 92 is disposed facing the inclined wall 74 as the first state of the first lower path member 92.

[0174] In the first state of the lower path member 86 , the second lower path member 112 forms a downstream portion of the relay path TA by being opposed to the upper wall 76 .

[0175] Fig.10 The state of the relay unit 60 viewed from the -X direction is shown.

[0176] As an example, the spring member 125 is configured as a helical torsion spring. One end of the spring member 125 is attached to the rear frame 64. The other end of the spring member 125 is attached to the side wall 105 of the first lower path member 92 in the +X direction.

[0177] The spring member 125 functions as a bistable spring. That is, when the first lower path member 92 is switched from the first state to the second state, the spring member 125 presses the first lower path member 92 in the -Z direction. When the first lower path member 92 is switched from the second state to the first state, the spring member 125 presses the first lower path member 92 in the +Z direction.

[0178] As an example, the spring member 127 is configured as a cylindrical torsion spring. One end of the spring member 127 is attached to the rear frame 64. The other end of the spring member 127 is attached to the side wall 122 of the second lower path member 112 in the +X direction.

[0179] The spring member 127 functions as a bistable spring. That is, in the relay path TA ( Figure 5When the second lower path member 112 is switched from the open state to the closed state, the spring member 127 presses the second lower path member 112 in the -Z direction. When the second lower path member 112 is switched from the open state to the closed state, the spring member 127 presses the second lower path member 112 in the +Z direction.

[0180] like Fig.11 As shown, in the second state of the lower path member 86, the first lower path member 92 is away from the inclined wall 74 in the -Z direction, and the upstream portion of the relay path TA is opened toward the placement portion 40. The configuration state in which the first lower path member 92 opens the upstream portion of the relay path TA is the second state of the first lower path member 92.

[0181] In the second state of the lower path member 86, as an example, the second lower path member 112 is separated from the upper wall 76 in the -Z direction, and the downstream portion of the relay path TA is opened toward the placement portion 40. It should be noted that the configuration state in which the second lower path member 112 opens the downstream portion of the relay path TA is the open state of the second lower path member 112.

[0182] like Fig.12 As shown, the first lower path member 92 is in the second state and the second lower path member 112 is in the closed state, which is included in the second state of the lower path member 86. In this case, the paper P discharged from the discharge unit 30 is conveyed to the placement unit 40 along the first lower path member 92.

[0183] like Fig.13 As shown, when the first lower path member 92 is in the second state and the second lower path member 112 is in the closed state, the paper P discharged to the placement portion 40 can be taken out only from the inside of the opening area S indicated by the dashed line S as viewed from the +X direction.

[0184] When viewed from the +X direction, the open area S is an area surrounded by the front frame 63 , the placement portion 40 , the first lower path member 92 , and the second lower path member 112 .

[0185] like Fig.14 As shown, the recessed portion 104 and the recessed portion 121 are open in the +Z direction and the -Z direction. Thus, the convex portion 103 and the recessed portion 121 can move relative to each other in the Z direction. The convex portion 119 and the recessed portion 104 can move relative to each other in the Z direction.

[0186] When the lower path member 86 is in the first state, specifically, when the first lower path member 92 is in the first state and the second lower path member 112 is in the closed state, a portion of the convex portion 103 is inserted into the concave portion 121 . A portion of the convex portion 119 is inserted into the concave portion 104 .

[0187] When the lower path member 86 is in the first state, the convex portion 103 and the concave portion 121 are spaced apart from each other in the X and Z directions and are in a non-contact state. The convex portion 119 and the concave portion 104 are spaced apart from each other in the X and Z directions and are in a non-contact state.

[0188] With the above configuration, when the paper P passes from the first lower path member 92 to the second lower path member 112 , a portion of the paper P in the X direction is supported by at least one of the first lower path member 92 and the second lower path member 112 .

[0189] like Figure 2 as well as Figure 8 As shown, the opening and closing sensor 56 detects the detected portion 128 of the second lower path member 112. Specifically, the opening and closing sensor 56 is an example of a detection unit that detects the open state and the closed state of the second lower path member 112. In other words, the opening and closing sensor 56 detects the open state and the closed state of the second lower path member 112.

[0190] The opening and closing sensor 56 is provided in the -Y direction relative to the detected portion 128 in the second lower path member 112 in the closed state. As an example, the opening and closing sensor 56 is an optical sensor having a light emitting portion and a light receiving portion (not shown). Information on the presence or absence of light detected by the opening and closing sensor 56 is sent to the control unit 50.

[0191] When the light emitted from the light emitting portion is received by the light receiving portion, the opening / closing sensor 56 determines that the state of the detected portion 128 is not detected, that is, the second lower path component 112 is in the open state, and sends non-detection information to the control unit 50. In addition, when the light emitted from the light emitting portion is not received by the light receiving portion, the opening / closing sensor 56 determines that the state of the detected portion 128 is detected, that is, the second lower path component 112 is in the closed state, and sends detection information to the control unit 50. In this way, the opening / closing sensor 56 directly detects the open state and the closed state of the second lower path component 112.

[0192] Figure 2 The interlock circuit 58 is shown in the lower path component 86 ( Figure 5 ) is in the first state. In addition, the interlock circuit 58 cannot be energized when the lower path component 86 is in the second state. Here, by detecting whether the interlock circuit 58 can be energized, the first state and the second state of the lower path component 86 can be detected. For the circuit using the interlock circuit 58, a well-known interlock circuit can be used. It should be noted that even if only the interlock circuit 58 is detected whether it can be energized, the open and closed state of the first lower path component 92 and the open and closed state of the second lower path component 112 cannot be distinguished.

[0193] In the present embodiment, as an example, the control unit 50 determines the first state and the second state of the first lower path member 92 based on the detection result of the opening and closing sensor 56 and the detection result of the interlock circuit 58 .

[0194] Specifically, when the opening / closing sensor 56 detects the closed state of the second lower path member 112 and the interlock circuit 58 cannot be energized, the control unit 50 determines that the first lower path member 92 is in the second state. On the other hand, when the interlock circuit 58 can be energized, the control unit 50 determines that the first lower path member 92 is in the first state.

[0195] When the paper P is being conveyed and the opening and closing sensor 56 detects that the second lower path member 112 is in an open state, the control unit 50 stops the paper P discharge unit 30 from discharging the paper.

[0196] Next, the operation of the recording system 1 according to the first embodiment will be described. Figures 1 to 14 , the recording of individual figure numbers is omitted.

[0197] According to the recording system 1, when the post-processing unit 6 is operable, the state of the lower path member 86 is in the first state. After the paper P recorded by the recording unit 20 is discharged from the discharge unit 30 in the E direction, it is conveyed to the post-processing unit 6 by the relay unit 60 and post-processed in the post-processing unit 6.

[0198] On the other hand, when the post-processing unit 6 cannot be operated, the lower path member 86 is in the second state, so that the relay path TA is opened toward the placement portion 40. In addition, as an example, the second lower path member 112 is in the closed state.

[0199] The paper P recorded by the recording unit 20 is discharged from the discharge unit 30 in the direction E, and then falls from the open portion of the relay path TA toward the placement unit 40 and is placed on the placement unit 40 .

[0200] Thus, when the post-processing unit 6 cannot be operated, the operation of the recording system 1 can be prevented from being stopped by placing the paper P on the placing portion 40, thereby suppressing a decrease in the productivity of the recording system 1. In addition, since the paper P is discharged using the placing portion 40 provided in the apparatus main body 12, it is possible to suppress an increase in the size of the recording system 1 compared to a configuration in which the paper P is discharged to a device other than the apparatus main body 12.

[0201] According to the recording system 1 , when the state of the lower path member 86 is switched to the first state or the second state, since the rotating mechanism 80 is not provided in the lower path member 86 , the state of the lower path member 86 can be switched more easily than in a configuration in which the rotating mechanism 80 is provided in the lower path member 86 .

[0202] According to the recording system 1 , by rotating the lower path member 86 about the first rotation axis 87 , the movable range of the lower path member 86 is made smaller than that of a configuration in which the lower path member 86 is slid, thereby reducing the space required for switching between the first state and the second state.

[0203] According to the recording system 1, since the lower path member 86 is divided into the first lower path member 92 and the second lower path member 112, and the first lower path member 92 is rotatable, when poor transportation of the paper P occurs in the middle of the lower path member 86, the removal operation of removing the paper P from the lower path member 86 can be simply performed.

[0204] According to the recording system 1, when the paper P remains in the relay unit 60 due to poor conveyance, the first lower path member 92 and the second lower path member 112 are rotated to open the relay unit 60. In this case, the area of ​​the open relay path TA becomes larger, so that the paper P can be easily taken out from the relay unit 60.

[0205] According to the recording system 1 , when the second lower path member 112 is in the open state, the paper P is not discharged from the discharge section 30 toward the relay unit 60 , thereby preventing the paper P from falling from the relay path TA on the way to the post-processing unit 6 .

[0206] According to the recording system 1, in the first state in which at least a part of the convex parts 103 and 119 is inserted into the concave parts 104 and 121, the paper P conveyed by the relay unit 60 is supported by at least one of the first lower path member 92 and the second lower path member 112 at any position in the E direction. Thus, when viewed from the X direction, compared with a configuration in which the first lower path member 92 and the second lower path member 112 do not overlap in the E direction, it is possible to suppress poor conveyance of the paper P in the relay unit 60.

[0207] Furthermore, since the recesses 104 and 121 and the protrusions 103 and 119 are movable relative to each other in the Z direction, interference between the first lower path component 92 and the second lower path component 112 can be prevented even if either the first lower path component 92 or the second lower path component 112 is retracted from the relay path TA first.

[0208] According to the recording system 1 , when the lower path member 86 is in the first state, the paper P entering the lower path member 86 is not bent, and therefore the relay unit 60 can easily convey the paper P.

[0209] On the other hand, when the lower path member 86 is in the second state, the bending portion 34 bends the paper P entering the lower path member 86 to increase the rigidity of the paper P against the force acting in the direction E. As a result, the paper P is less likely to curl, and a decrease in the loading performance of the paper P in the loading portion 40 due to the curling of the paper P can be suppressed.

[0210] According to the recording system 1, when the paper P is discharged from the discharge section 30, the lower path component 86 will not be located at a position closer to the top than the front end of the discharge guide 32 in the Z direction orthogonal to the E direction, thereby suppressing the poor conveyance of the paper P caused by the front end of the paper P hanging on the lower path component 86.

[0211] According to the recording system 1 , when the lower path member 86 is in the first state, the paper P is discharged toward the relay unit 60 at the first speed V1 .

[0212] On the other hand, when the lower path member 86 is in the second state, the movement of the paper P may be restricted by the receiving portion 94 .

[0213] Here, according to the recording system 1, when the lower path member 86 is in the second state, the paper P is discharged at the second speed V2 faster than the first speed V1 in the discharge section 30, and the accelerated paper P passes over the receiving section 94 and falls toward the placement section 40. Thus, compared with a configuration in which the discharge speed of the paper P is not changed, discharge failure of the paper P can be suppressed.

[0214] According to the recording system 1, when the determination unit 54 determines that the size of the paper P in the E direction is a size that cannot be placed on the placement unit 40, the paper P of the size that cannot be placed is not discharged to the placement unit 40. Thus, the downstream end of the paper P in the E direction can be prevented from passing over the placement unit 40 and contacting the post-processing unit 6 or the like to be deformed.

[0215] Implementation Method 2

[0216] Next, a recording system 130 according to Embodiment 2 will be described with reference to the drawings. It should be noted that the same components as those of the recording system 1 according to Embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

[0217] like Fig.15 As shown, the recording system 130 of the second embodiment has the following structure: in the recording system 1 ( Figure 1 ), replace the upper path component 72 ( Figure 5) and an upper path component 132 is provided to replace the first lower path component 92 ( Figure 5 ) and a first lower path member 136 as an example of a lower path member is provided. The other configurations are the same as those of the first embodiment.

[0218] The upper path member 132 forms an upper portion in the +Z direction relative to the center of the relay path TA in the Z direction. The upper path member 132 is provided with a rotation mechanism 80. As an example, the upper path member 132 has an inclined wall 134 and an upper wall 76.

[0219] The inclined wall 134 is located downstream of the discharge guide 32 in the E direction. The inclined wall 134 is inclined so that the end in the -Y direction is closer to the +Z direction than the end in the +Y direction. In other words, the inclined wall 134 is a wall extending obliquely upward relative to the discharge guide 32.

[0220] The first lower path member 136 is formed in a plate shape having a predetermined thickness. The first lower path member 136 is formed in a rectangular shape whose dimension in the X direction is longer than that in the E direction. It should be noted that the upstream end of the first lower path member 136 in the E direction is set as the base end 137. In addition, the downstream end of the first lower path member 136 in the E direction is set as the front end 138. That is, the front end 138 is located at a position opposite to the base end 137. The base end 137 is rotatably provided on the first rotating shaft 87.

[0221] Here, when the first lower path member 136 rotates about the first rotation axis 87 , the trajectory drawn by the distal end portion 138 is referred to as a rotation trajectory R. In addition, a region inside the rotation trajectory R is referred to as a rotation region SR.

[0222] The placement portion 40 is located outside the rotation trajectory R of the front end portion 138. In other words, when the first lower path member 136 rotates, the first lower path member 136 and the placement portion 40 are not in contact.

[0223] Next, the operation of the recording system 130 according to the second embodiment will be described.

[0224] According to the recording system 130, since there is no placement section 40 in the rotation region SR of the first lower path member 136, the first lower path member 136 can be rotated to a position facing the vertical wall 13. That is, the first lower path member 136 can be rotated regardless of the arrangement of the placement section 40. Thus, a space for accommodating the paper P is ensured between the first lower path member 136 and the placement section 40, so when the first lower path member 136 is in the second state, it is possible to suppress a decrease in the number of paper P that can be placed on the placement section 40.

[0225] Implementation 3

[0226] Next, the recording system 140 according to Embodiment 3 will be described with reference to the drawings. It should be noted that the same components as those of the recording system 1 or the recording system 130 are denoted by the same reference numerals, and description thereof will be omitted.

[0227] like Fig.16 As shown, the recording system 140 of the third embodiment has the recording system 1 ( Figure 1 ) is provided with a plurality of protrusions 142 and a plurality of recesses 144. The other structures are the same as those of the recording system 1.

[0228] The plurality of protrusions 142 are provided on the upper surface 44A of the placement portion 40 . The plurality of protrusions 142 protrude from the upper surface 44A in the +B direction. As an example, the plurality of protrusions 142 are formed in a quadrangular column shape extending in the A direction. The plurality of protrusions 142 can support the paper P placed on the protrusions 142 .

[0229] A plurality of recessed portions 144 are provided in the convex portion 103 of the first lower path member 92. Specifically, the plurality of recessed portions 144 are portions where the ends of the convex portion 103 in the +A direction are cut off, and are arranged at intervals in the X direction. The plurality of recessed portions 144 are open in the +A direction and the -B direction. The recessed portion 144 has a size that allows a portion of the protruding portion 142 in the A direction to be inserted in the second state of the first lower path member 92. Thus, in the second state of the first lower path member 92, a portion of the protruding portion 142 can be inserted into the recessed portion 144.

[0230] Here, when viewed from the X direction, the edge of the recessed portion 144 and the protruding portion 142 overlap within a range of a height H1 in the Z direction.

[0231] Next, the operation of the recording system 140 according to the third embodiment will be described.

[0232] According to the recording system 140, in the configuration in which the placement section 40 is provided with the protrusion 142, when the first lower path member 92 is in the second state, the first lower path member 92 and the placement section 40 can be arranged close to each other by inserting the protrusion 142 into the recess 144 of the first lower path member 92. In other words, the rotation range of the first lower path member 92 is not easily restricted by the protrusion 142. Thus, in the configuration in which the first lower path member 92 is in contact with the placement section 40, a larger space can be ensured to be formed on the placement section 40.

[0233] Implementation 4

[0234] Next, a recording system 150 according to Embodiment 4 will be described with reference to the drawings. It should be noted that the same components as those of the recording systems 1, 130, and 140 are denoted by the same reference numerals, and description thereof will be omitted.

[0235] like Fig.17 As shown, the recording system 150 of the fourth embodiment has the following structure: in the recording system 130 ( Fig.15 ), the first rotating shaft 87 and the second rotating shaft 88 are not provided, a lower path member 152 is provided instead of the lower path member 86, and a lifting unit 156 is added. It should be noted that the other configurations are the same as those of the recording system 130.

[0236] As an example, the lower path member 152 includes a first lower path member 153 and a second lower path member 154 located downstream in the E direction with respect to the first lower path member 153 .

[0237] The first lower path member 153 is provided so as to be retractable from the relay path TA in the −Z direction.

[0238] As the first lower path component 153 withdraws from the relay path TA, the lower path component 152 switches from the first state to the second state.

[0239] Specifically, the first lower path member 153 has a predetermined thickness in the B direction and is formed in a plate shape extending in the A direction. The first lower path member 153 switches between a first state and a second state by driving a lifting unit 156 described later. In the first state, the first lower path member 153 faces the inclined wall 74 and forms the relay path TA. In the second state in which the first lower path member 153 is retracted from the relay path TA in the -Z direction, it is placed on the placement unit 40.

[0240] The second lower path member 154 is formed in a plate shape having a predetermined thickness in the Z direction. In addition, as an example, the second lower path member 154 is fixed in a state facing the upper wall 76 and forming the relay path TA.

[0241] As an example, the lifting unit 156 is configured to include a linear slider (not shown). The lifting unit 156 has a movable unit (not shown) that rises in the +Z direction or falls in the -Z direction when energized. The first lower path member 153 is attached to the movable unit.

[0242] Next, the operation of the recording system 150 according to the fourth embodiment will be described.

[0243] According to the recording system 150, the lower path member 152 is divided into a first lower path member 153 and a second lower path member 154. Here, since the first lower path member 153 can be retracted from the relay path TA, when a conveyance failure of the paper P occurs in the middle of the relay path TA, the paper P can be easily removed from the lower path member 152 by retracting the first lower path member 153 from the relay path TA.

[0244] The recording systems according to the embodiments and modifications of the present invention are based on the above-described configurations, and it is apparent that some configurations may be changed, omitted, combined, etc. without departing from the gist of the present invention.

[0245] First Modification

[0246] exist Fig.18 , as a first modification of the recording system 1, a configuration in which a retreat path TB and a retreat tray 25 are provided in the apparatus body 12 is shown. The retreat path TB branches from a part of the conveying path T and extends to the end in the +Y direction of the apparatus body 12. The retreat tray 25 receives the paper P discharged from the retreat path TB.

[0247] In the first modified example of the recording system 1, the operation of the post-processing unit 6 is stopped, and when the paper P is discharged from the discharge unit 30 to the loading unit 40 via the relay unit 60, if the amount of paper P loaded on the loading unit 40 exceeds a set amount, the paper P is discharged to the evacuation tray 25 via the evacuation path TB. This can prevent the paper P from being discharged to the loading unit 40 in excess of the allowable amount.

[0248] Second Modification

[0249] exist Fig.19 As a second modification of the recording system 1, a method is shown in which the upper path component 72 and the lower path component 86 ( Figure 5 ) and has a linear upper path member 162 and a plate-like lower path member 164. In the second modification, the first rotating shaft 87 ( Figure 5 ).

[0250] The upper path member 162 is inclined such that the end portion in the +Y direction is closer to the +Z direction than the end portion in the −Y direction.

[0251] The lower path member 164 has a predetermined thickness in the B direction and extends in the +A direction. The base end portion 165 of the lower path member 164 in the +A direction rotates around the second rotation axis 88. The lower path member 164 switches between a first state in which the lower path member 164 forms the relay path TA together with the upper path member 162 and a second state in which the lower path member 164 retreats in the -Z direction from the relay path TA.

[0252] In the second modification of the recording system 1, when the lower path member 164 is in the second state, the paper P is discharged to the space portion on the placement portion 40. In this way, the lower path member 164 may be formed of a single member.

[0253] It should be noted that the first rotating shaft 87 may be provided instead of the second rotating shaft 88, so that the base end portion of the lower path member 164 in the -A direction rotates around the first rotating shaft 87. In addition, the lifting portion 156 ( Fig.17 ) to raise and lower the lower path component 164.

[0254] Other variations

[0255] In the recording system 1, a roller constituting a part of the rotating mechanism section 80 may be provided in the lower path member 86. The first rotating shaft 87 may not be provided, and the first lower path member 92 may be removed to switch from the first state to the second state. The opening and closing sensor 56 may not be provided. The concave portions 104 and 121 and the convex portions 103 and 119 may not be formed in the first lower path member 92 and the second lower path member 112, and the first lower path member 92 and the second lower path member 112 may be separately configured in the E direction. The bending portion 34 may not be provided. The first lower path member 92 may be located below the end portion of the discharge guide 32 in the E direction in the Z direction. The discharge section 30 may discharge the paper P at a fixed discharge speed regardless of the first state and the second state of the lower path member 86. In addition, the determination section 54 may not be provided, and the paper P may be discharged by the discharge section 30. In addition, instead of inserting the protruding portion 142 into the recessed portion 144 provided in the convex portion 103 of the first lower path member 92 , the protruding portion 142 may be inserted into the recessed portion 104 .

[0256] For the second lower path member 112 , a state in which the relay path TA is formed may be referred to as the first state, and a state in which the relay path TA is opened may be referred to as the second state.
