DESCRIPTION OF EMBODIMENTS

The present disclosure will be schematically described below.

A medium transport device according to a first aspect is a medium transport device installable at an in-body discharge portion in a recording device including a recording unit, the recording unit being configured to perform recording on a medium, the medium transport device including: a transport unit positioned, in the recording device, between a first discharge path through which the medium is discharged to the in-body discharge portion and a first processing unit configured to perform first processing on the medium discharged to the in-body discharge portion, the transport unit being configured to transport the medium discharged from the first discharge path to the first processing unit, and an operation unit configured to enable manual operation of the transport unit.

According to the aspect, since the medium transport device including the transport unit positioned between the first discharge path and the first processing unit includes the operation unit that enables manual operation of the transport unit, it is possible to move the medium that is jammed in a state of being engaged with the transport unit, and paper jam processing can be appropriately performed.

This effect can be obtained both in a case in which the first processing unit is slidable and a case in which the first processing unit is not slidable. In particular, the paper jam processing can be appropriately performed when the first processing unit is not slidable.

According to a second aspect, with respect to the first aspect, the transport unit includes a rotating body configured to be rotated by a power of a drive source to transport the medium. The operation unit includes an input unit configured to enable manual input of an operating force, and a switching unit configured to switch between a transmission state in which the operating force is transmitted to the rotating body, and a decoupled state in which the operating force is not transmitted to the rotating body. When the rotating body is driven by the power of the drive source, the switching unit is in the decoupled state. In other words, the operation unit includes the input unit to which a rotational force can be manually input.

According to the aspect, since the switching unit is in the decoupled state when the rotating body is driven by the power of the drive source, the power of the drive source is not transmitted to the input portion when the rotating body is driven by the power of the drive source. In this way, when the drive source drives the rotating body, the input portion does not become a load, the transport unit can be appropriately driven by the drive source, and noise and wear of components can also be suppressed.

According to a third aspect, with respect to the second aspect, the operation portion further includes a first support portion supporting the input unit, and a second support portion supporting the switching unit. The first support portion and the second support portion are rotatable relative to each other.

According to the aspect, since the first support portion supporting the input unit and the second support portion supporting the switching unit are rotatable relative to each other, when the operation unit is passed through a space through which it is difficult for the operation unit to pass when attaching the operation unit, such as a narrow space or a space with an obstacle, the operation unit can be passed through, and the operation unit can thus be attached.

Note that this aspect is not limited to the above-described second aspect, and may also be applied to the above-described first aspect.

According to a fourth aspect, with respect to the second aspect, the rotating body transports the medium downstream in a transport direction by rotating in a first rotation direction, and transports the medium upstream in the transport direction by rotating in a second rotation direction opposite to the first rotation direction. The rotating body is rotatable only in the second rotation direction when the operating force is input to the input unit.

When the jammed medium is transported downstream in the transport direction from the transport unit, that is, toward the first processing unit, there is a concern that it may become impossible to take out the medium. According to the aspect, when the operating force is input to the operation knob, since the rotating body can only rotate in a rotation direction in which the medium is transported upstream (the second rotation direction), it is possible to suppress the occurrence of a problem in which the jammed medium is transported toward the first processing unit and cannot be taken out.

Note that this aspect is not limited to the above-described second aspect, and may also be applied to the above-described third aspect.

According to a fifth aspect, with respect to the first aspect, the medium transport unit includes a unit mounting portion mounted with the first processing unit. The unit mounting portion is configured to be further mounted with a second processing unit being a unit positioned downstream of the first processing unit in a transport direction of the medium, the second processing unit being configured to perform second processing on the medium received from the first processing unit.

According to the aspect, since the second processing unit can be further mounted to the unit mounting portion to which the first processing unit is mounted, it is possible to increase the types of processing performed on the medium. Note that this aspect is not limited to the above-described first aspect, and may also be applied to any of the above-described second to fourth aspects.

According to a sixth aspect, with respect to the fifth aspect, the first processing is processing of punching the medium, and the second processing is processing of binding the medium.

According to the aspect, in a configuration in which the first processing is the processing of punching the medium, and the second processing is the processing of binding the medium, the operational effects of the above-described fifth aspect are obtained.

According to a seventh aspect, with respect to the first aspect, the operation portion is attachable and detachable.

According to the aspect, since the operation unit is attachable and detachable, it is possible to effectively utilize a mounting space of the operation unit when the operation unit is not mounted.

Note that this aspect is not limited to the above-described first aspect, and may also be applied to any of the above-described second to sixth aspects.

A recording system according to an eighth aspect includes the medium transport device according to any of the above-described first to seventh aspects, and the recording device including the recording unit configured to perform recording on the medium. A drive source is provided at the recording device.

According to the aspect, in the recording system, the operational effects of any one of the above-described first to seventh aspects can be obtained.

According to a ninth aspect, with respect to the eighth aspect, the recording system includes a first path forming member attachable to and detachable from a device main body including the first discharge path. The first discharge path is formed by attaching the first path forming member to the device main body.

According to the aspect, it is possible to expose the first discharge path by removing the first path forming member, and it is possible to easily remove the jammed medium when the jam occurs in the first discharge path.

According to a tenth aspect, with respect to the ninth aspect, the recording device includes an opening/closing body provided openably and closably with respect to the device main body, the opening/closing body being configured to be opened when the first path forming member is attached or detached. The operation unit is exposed by opening the opening/closing body.

According to the aspect, by opening the opening/closing body, it is possible to both operate the operation unit and access the first discharge path, and convenience for a user is improved.

According to an eleventh aspect, with respect to the eighth aspect, the recording unit is positioned below the transport unit, and the transport unit includes a holding unit configured to hold foreign matter generated in a transport path through which the medium is transported.

In a configuration in which the recording unit is positioned below the transport unit, there is a concern that foreign matter generated in the transport unit may fall toward the recording unit and a recording quality may deteriorate. However, according to the aspect, since the transport unit includes the holding unit capable of holding the foreign matter generated in the transport path through which the medium is transported, it is possible to suppress fall of the foreign matter generated in the transport path toward the recording unit, and it is thus possible to suppress deterioration in recording quality.

Note that this aspect is not limited to the above-described eighth aspect, and may also be applied the above-described ninth or tenth aspect.

According to a twelfth aspect, with respect to the eighth aspect, the recording unit performs recording by ejecting a liquid onto the medium.

In a configuration in which the recording unit performs recording by ejecting the liquid onto a medium, the medium is easily deformed as a result of the ink being ejected onto the medium and thus a jam is likely to occur. However, since the operation unit that enables manual operation of the transport unit is provided, it is possible to move the jammed medium, and it is possible to appropriately perform paper jam processing.

Note that this aspect is not limited to the above-described eighth aspect, and may also be applied to any one of the above-described ninth to eleventh aspects.

A recording system according to a thirteenth aspect includes the medium transport device according to any one of the second to fourth aspects, and the recording device including the recording unit configured to perform recording on the medium. The recording device includes an opening/closing body provided openably and closably with respect to a device main body including the first discharge path, the opening/closing body being configured to be opened when the first discharge path is accessed. The operation unit is exposed by opening the opening/closing body. The medium is fed into the first discharge path by inputting the operating force to the input unit. The switching unit includes a pressed portion configured to be pressed by the opening/closing body. When the opening/closing body is in a closed state, the switching unit is in the decoupled state as a result of the pressed portion being pressed by the opening/closing body, and when the opening/closing body is in an open state, the switching unit is in the transmission state as a result of the pressed portion not being pressed by the opening/closing body.

According to the aspect, since the state of the switching unit is switched in conjunction with the opening and closing of the opening/closing body, it is not necessary for the user to switch the state of the switching unit by himself or herself, and convenience for the user is improved.

According to a fourteenth aspect, with respect to the thirteenth aspect, the transport unit includes a toothed gear configured to rotate coaxially with the rotating body. The switching unit includes a switching gear positioned, in the transmission state, at a coupling position at which the switching gear is coupled to the toothed gear, and positioned, in the decoupled state, at a separation position at which the switching gear is spaced apart from the toothed gear, a displacement portion including the pressed portion and configured to displace the switching gear from the coupling position to the separation position, and a pressing portion configured to press the switching gear toward the coupling position.

According to the aspect, since the switching unit is configured to switch between the decoupled state and the transmission state as a result of the switching gear being displaced between the coupling position and the separation position, the switching unit can be configured with a simple mechanism.

A recording system according to a fifteenth aspect includes the medium transport device according to the seventh aspect, and the recording device including the recording unit configured to perform recording on the medium. In addition to the first discharge path, a device main body of the recording device is configured to form a second discharge path positioned above the first discharge path, the second discharge path being a path through which the medium is discharged to the in-body discharge portion. The first discharge path is formed by attaching a first path forming member attachable to and detachable from the device main body. The first discharge path and the second discharge path are formed by attaching, in place of the first path forming member, a second path forming member attachable to and detachable from the device main body. The operation portion is disposed, in the device main body, at a position at which the operation portion does not interfere with the first path forming member and at which the operation portion interferes with the second path forming member.

According to the aspect, since the second discharge path can be formed in addition to the first discharge path, a degree of freedom of use of the in-body discharge portion is improved.

Here, in a mode in which the medium is discharged to the in-body discharge portion using the second discharge path, the medium transport device and the first processing unit become an obstacle, and the medium transport device and the first processing unit are not used. For this reason, the operation portion is also unnecessary, and the operation portion can be removed. Then, since the operation portion is disposed at a position at which the operation portion interferes with the second path forming member, the second path forming member forming the second discharge path is attached using a space secured by removing the operation portion. Such a configuration eliminates the need to secure a space for simultaneously mounting the second path forming member and the operation unit, making it possible to suppress an increase in device size.

The present disclosure will be specifically described below.

Hereinafter, an inkjet printer 1 that performs recording by ejecting a liquid represented by ink onto a medium represented by recording paper will be described as an example of a recording device. Hereinafter, the inkjet printer 1 is simply referred to as the printer 1.

An X-Y-Z coordinate system illustrated in each of the drawings is an orthogonal coordinate system in which a Y-axis direction is a width direction intersecting a transport direction of a medium and is also a device depth direction. Of the Y-axis direction, a +Y direction, which is a direction in indicated by an arrow, is a direction from the device front surface toward the device rear surface, and a −Y direction, which is opposite to the +Y direction, is a direction from the device rear surface toward the device front surface.

Further, the X-axis direction is a device width direction, and a +X direction, which is a direction indicated by an arrow when viewed from an operator of the printer 1, is the left side, and the −X direction, which is the opposite direction, is the right side. The Z-axis direction is a vertical direction, that is, a device height direction. A +Z direction, which is a direction indicated by an arrow, is an upward direction, and a −Z direction, which is the opposite direction, is a downward direction. Hereinafter, the term “upward” when used herein means the +Z direction, and the term “downward” when used herein means the −Z direction.

Further, a G-axis direction is a normal direction with respect to an ink ejection surface 35 of a line head 34 to be described later. A +G direction, which is a direction indicated by an arrow, is a direction in which a head unit 33 to be described later moves away from a transport belt 7, and a −G direction, which is the opposite direction, is a direction in which the head unit 33 approaches the transport belt 7.

An F-axis direction is a direction parallel to the ink ejection surface 35 and is a medium transport direction at a position facing the ink ejection surface 35. A +F direction, which is a direction indicated by an arrow, is downstream in the transport direction and a −F direction, which is the opposite direction, is upstream in the transport direction. Note that, hereinafter, the direction in which the medium is transported may be referred to as “downstream” and the direction opposite thereto may be referred to as “upstream”.

In FIG. 1, the medium transport path is illustrated by a dashed line. In the printer 1, the medium is transported along the medium transport path indicated by the dashed line.

A device main body 2 of the printer 1 is provided with a first medium cassette 3 and a second medium cassette 4, which accommodate the medium before feeding. Reference signs P denote the medium stored in each of the medium cassettes. The first medium cassette 3 and the second medium cassette 4 are provided so as to be attachable to and detachable from the device main body 2, from the device front side.

The first medium cassette 3 is provided with a pick roller 9 that feeds out the accommodated medium, and the second medium cassette 4 is provided with a pick roller 10 that feeds out the accommodated medium.

Further, the first medium cassette 3 is provided with a feed roller pair 11 that feeds the fed out medium in an obliquely upward direction. The second medium cassette 4 is provided with a feed roller pair 12 that feeds the fed out medium obliquely upward, and a transport roller pair 13 that transports the medium upward.

Note that, hereinafter, unless otherwise specified, a “roller pair” refers to a pair of rollers constituted by a driving roller driven by a motor (not illustrated) and a driven roller that is in contact with the driving roller and is driven to rotate.

The medium fed out from each of the medium cassettes is transported to a transport roller pair 16 by a transport roller pair 14 and a transport roller pair 15. The medium receiving a feeding force from the transport roller pair 16 is transported to a position between the line head 34 and the transport belt 7, that is, to a position facing the line head 34.

The line head 34 is provided at the head unit 33, and performs recording by ejecting the ink onto the surface of the medium. The line head 34 is an ink ejection head configured such that nozzles (not illustrated) for ejecting the ink cover an entire region in a medium width direction, and is configured as an ink ejection head capable of recording over the entire region in the medium width direction without moving in the medium width direction. The line head 34 is an example of a recording unit that performs recording on the medium.

In the −X direction with respect to the head unit 33, a plurality of ink cartridges 38 that store the ink, a mounting portion 39 to which the ink cartridge 38 is attachable and detachable, and a reservoir tank 40, which is a portion positioned between the ink cartridge 38 and the line head 34 in the ink flow path and which stores the ink supplied from the ink cartridge 38, are provided. The ink cartridge 38 is attachable and detachable from the device front side.

The ink stored in the reservoir tank 40 is supplied to the line head 34 via an ink tube 41.

A maintenance box 42 is provided below the reservoir tank 40. The maintenance box 42 is coupled to a maintenance portion (not illustrated) by an ink tube (not illustrated), and the ink (waste ink) discharged from the line head 34 to the maintenance portion is transported to the maintenance box 42 and stored therein.

The maintenance box 42 is attachable and detachable from the device front side.

The transport belt 7 and pulleys 8a and 8b constitute a belt unit 6. The transport belt 7 is an endless belt wound around the pulleys 8a and 8b disposed along the medium transport direction. The transport belt 7 rotates as a result of at least one of the pulleys 8a and 8b being driven by a motor (not illustrated).

The medium is transported to the position facing the line head 34 while being adsorbed to a belt surface of the transport belt 7.

The medium transport path passing through the position facing the line head 34 intersects both the horizontal direction and the vertical direction, and is configured to transport the medium in an obliquely upward direction. The obliquely upward transport direction is a direction including a −X direction component and a +Z direction component in FIG. 1, and with such a configuration, the horizontal dimension of the printer 1 can be reduced.

Note that, in the embodiment, the medium transport path passing through the position facing the line head 34 is set to an inclination angle in a range from 50° to 70° with respect to the horizontal direction, and more specifically, is set to an inclination angle of 60°.

After recording is performed on a first surface of the medium by the line head 34, the medium is further transported obliquely upward by a transport roller pair 17 positioned below the transport belt 7.

The medium transport path downstream of the transport roller pair 17 branches into two paths, and an upstream flap 23 is provided at the branching portion. The upstream flap 23 switches the traveling direction of the medium.

When the medium on which the recording has been performed is discharged as it is, the medium traveling direction downstream of the transport roller pair 17 is set to a direction toward a transport roller pair 20. The transport path downstream of the transport roller pair 20 will be described later.

When recording is to be further performed on a second surface in addition to the first surface of the medium, the medium traveling direction downstream of the transport roller pair 17 is set to a direction toward a transport roller pair 22. In this way, the medium passes through a branching position K1 and is fed from the branching position K1 to an upper switch-back path H3. The transport roller pair 22 is provided on the switch-back path H3, and the medium that has entered the switch-back path H3 is transported upward by the transport roller pair 22. Depending on the size of the medium, the leading end of the medium transported in the upward direction by the transport roller pair 22 protrudes from a switch-back discharge port 52 into an in-body discharge portion 30. Here, a first guide member 50 is provided at the in-body discharge portion 30, and the medium protruding into the in-body discharge portion 30 from the switch-back discharge port 52 is supported by the first guide member 50 so as not to hang down. Note that a reference sign 50a denotes a base portion that supports the first guide member 50. Depending on the size of the medium, the medium protruding into the in-body discharge portion 30 from the switch-back discharge port 52 further protrudes from the first guide member 50 in the +X direction. However, since the first guide member 50 is provided, the medium protruding into the in-body discharge portion 30 from the switch-back discharge port 52 is suppressed from coming into contact with a second discharge tray 28 (see FIG. 2) to be described later, and is suppressed from coming into contact with a first processing unit 110 or a second processing unit 120 (see FIG. 3) to be described later. That is, it is possible to suppress damage to the medium, an increase in a transport load, a transport failure, or the like.

When the trailing end of the medium that has entered the switch-back path H3 passes through the branching position Kl, the rotation direction of the transport roller pair 22 is switched, and thus the medium is transported downward.

The medium transported downward by the transport roller pair 22 receives a feeding force from the transport roller pair 18 and the transport roller pair 19, and reaches the transport roller pair 15. The medium is then transported once more to the belt unit 6 by the transport roller pair 16 downstream of the transport roller pair 15.

Of the medium that has been once more transported to the position facing the line head 34, the second surface, which is on the opposite side of the first surface on which the recording has already been performed, faces the line head 34, and the recording can be performed by the line head 34 on the second surface of the medium.

Next, the transport path downstream of the transport roller pair 20, that is, a discharge path of the medium, will be described. A first discharge path H1 illustrated in FIG. 1 and FIG. 2, and a second discharge path H2 illustrated only in FIG. 2 can be formed as the discharge path downstream of the transport roller pair 20.

The first discharge path H1 is formed by mounting a first path forming member 48 that is attachable to and detachable from the device main body 2 (FIG. 1) or by mounting a second path forming member 49 that is attachable to and detachable from the device main body 2, in place of the first path forming member 48.

The medium transported to the first discharge path H1 is discharged to the in-body discharge portion 30 by a first discharge roller pair 25, and is supported by a first discharge tray 27. Note that, as to be described in detail later, the first discharge path H1 is also used when processing is performed on the medium by the first processing unit 110 (see FIG. 3) and the second processing unit 120 (see FIG. 3).

The in-body discharge portion 30 is an internal space provided in the device main body 2, and is a space to which the medium on which recording has been performed is discharged. The in-body discharge portion 30 is open in the −Y direction and the +X direction. A user can take out the medium on which the recording has been performed from the in-body discharge portion 30. The in-body discharge portion 30 overlaps with a housing top surface of the device main body 2 when viewed from the +Z direction.

The first discharge tray 27 and the first discharge roller pair 25 are attachable to and detachable from the device main body 2.

As illustrated in FIG. 2, the second discharge path H2 can be formed above the first discharge path H1. The second discharge path H2 is formed by mounting the second path forming member 49 that is attachable to and detachable from the device main body 2. As described above, the second path forming member 49 is a member that can be attached and detached in place of the first path forming member 48 illustrated in FIG. 1.

A downstream flap 24 is provided below the second path forming member 49, and the transport of the medium transported by the transport roller pair 20 is switched, by the downstream flap 24, between transport to the first discharge path H1 and transport to the second discharge path H2.

The second discharge tray 28 and a second discharge roller pair 26 are attachable to and detachable from the upper portion of the first discharge tray 27 in the in-body discharge portion 30. The medium transported to the second discharge path H2 is discharged to the in-body discharge portion 30 by the second discharge roller pair 26, and is supported by the second discharge tray 28.

The second discharge tray 28 is detachably provided in the in-body discharge portion 30. When the second discharge tray 28 is mounted, the first guide member 50 and the base portion 50a illustrated in FIG. 1 are removed. The second path forming member 49, the second discharge roller pair 26, and a second guide member 51 are mounted in place of the first guide member 50 and the base portion 50a. The second guide member 51 has a function the same as or similar to that of the above-described first guide member 50. That is, the second guide member 51 is a member that supports the medium protruding into the in-body discharge portion 30 from the switch-back discharge port 52.

Note that a configuration may be adopted in which the second guide member 51 is omitted by leaving the first guide member 50 mounted.

The first path forming member 48 and the second path forming member 49 can be attached and detached by opening a first opening/closing body 45 provided in the side surface of the device main body 2 in the −X direction, and a second opening/closing body 46 provided on the inside of the first opening/closing body 45. FIG. 4 illustrates a state in which the second path forming member 49 is mounted, as an example. The first opening/closing body 45 and the second opening/closing body 46 are opening/closing bodies provided in the side surface of the device main body 2 in the −X direction so as to be openable and closable, and are opening/closing bodies that are opened when the user accesses the first discharge path H1 or the second discharge path H2. The second opening/closing body 46 is located on the inside of the first opening/closing body 45. When the first opening/closing body 45 is opened, the medium transport path from the transport roller pair 17 to the transport roller pair 22 and the switch-back path H3 above the transport roller pair 22 can be opened.

By further opening the second opening/closing body 46 in addition to the first opening/closing body 45, the medium transport path between the transport roller pair 17 and the transport roller pair 20 can be exposed. At this time, when the second path forming member 49 is mounted, the second discharge path H2 can be exposed. Further, by removing the second path forming member 49 from this state, the first discharge path H1 can be exposed.

When the first path forming member 48 is mounted, the medium transport path between the transport roller pair 17 and the transport roller pair 20 can be exposed by opening the second opening/closing body 46. Further, by removing the first path forming member 48 from this state, the first discharge path H1 can be exposed.

Note that, when the first opening/closing body 45 and the second opening/closing body 46 are opened, an operation unit 80 (see FIG. 8) to be described later is exposed. The operation unit 80 will be described in detail later.

Further, as illustrated in FIG. 3, a medium transport device 60, the first processing unit 110, and the second processing unit 120 are attachable to and detachable from the in-body discharge portion 30. When mounting the medium transport device 60, the first discharge tray 27 and the first discharge roller pair 25 are removed from the state illustrated in FIG. 1, the medium transport device 60 is mounted in place of the first discharge tray 27 and the first discharge roller pair 25, and then the first processing unit 110 and the second processing unit 120 are mounted.

Note that at this time, the first processing unit 110 and the second processing unit 120 are configured to be mounted without removing the above-described first guide member 50. FIG. 16 is a view viewed in the direction of the first guide member 50 at a position X1 illustrated in FIG. 3, in which the outer shape of the first guide member 50 and the outer shape of the first processing unit 110 are indicated by solid lines, the outer shape of the device main body 2 is indicated by two-dot chain lines, and a remaining configuration is not illustrated. As illustrated in FIG. 16, a recess 110a is formed in the first processing unit 110, and the first guide member 50 can be disposed on the inside of the recess 110a. In this way, when mounting the first processing unit 110 and the second processing unit 120, the first processing unit 110 and the second processing unit 120 can be mounted without removing the first guide member 50.

Note that, although not illustrated in the drawings, the second processing unit 120 is also provided with a similar recess, so also when mounting only the second processing unit 120 without mounting the first processing unit 110, the second processing unit 120 can be mounted without removing the first guide member 50.

Further, a relay transport device (not illustrated), which relays and transports the medium to an external processing unit (not illustrated) that can be installed in the +X direction with respect to the device main body 2, can be attached to the in-body discharge portion 30, and a recess that avoids interference with the second guide member 51 is also formed in the relay transport device (not illustrated).

Referring back to FIG. 3, the medium transport device 60, the first processing unit 110, and the second processing unit 120 are mounted to the printer 1 to constitute a recording system 1S together with the printer 1.

In the embodiment, the first processing unit 110 performs punching processing, as first processing, on the medium. The reference sign 110 denotes the first processing unit that performs the punching processing on the medium. Further, in the embodiment, the second processing unit 120 performs binding processing, as second processing, on the medium. A reference sign 121 denotes the second processing unit that performs the binding processing on the medium. Further, a reference sign 122 denotes a processing tray on which the medium is temporarily stacked. The medium on which the binding processing has been performed is discharged toward a stacking tray 123 by a discharge unit (not illustrated), and is stacked. Note that details of a medium transport path and a medium transport unit in the first processing unit 110 and the second processing unit 120 are not illustrated and described. Further, the first processing and the second processing are examples, and other processing may be performed.

Further, although the two processing units, that is, the first processing unit 110 and the second processing unit 120, are provided in the embodiment, only one of the two processing units may be provided. Further, examples of processing content in the processing unit in this case include binding processing using a stapler or the like, punching processing of punching a hole in the medium, saddle stitching processing of saddle stitching a media bundle, and shift discharge processing of alternately shifting a discharge position of the media bundle in the medium width direction and discharging the media bundle.

The first processing unit 110 and the second processing unit 120 described above are mounted to a unit mounting portion 73 (see also FIG. 5) constituting the medium transport device 60, and are fixed to the medium transport device 60 by screws (not illustrated).

In FIG. 3, the medium transport device 60 is provided with a transport unit 61 that is positioned between the first discharge path H1 and the first processing unit 110, and transports the medium discharged from the first discharge path H1 to the first processing unit 110. The transport unit 61 is configured integrally with the unit mounting portion 73.

The transport unit 61 is provided with a transport roller pair 62, and the medium is transported toward the first processing unit 110 by rotation of the transport roller pair 62. In FIG. 3, a reference sign 59 denotes a drive motor that is a drive source of the transport roller pair 62. The transport roller pair 62 includes a driving roller 64 that is driven by the driving motor 59 and a driven roller 65 that can be driven to rotate. The driving roller 64 is an example of a rotating body that transports the medium by rotating in contact with the medium.

As illustrated in FIG. 5, the transport unit 61 is provided with a guide frame 71 above a base frame 70. The medium discharged from the first discharge path H1 is guided toward the transport roller pair 62 by the guide frame 71.

As illustrated in FIG. 6, guide ribs 71a are formed at the guide frame 71, and the medium discharged from the first discharge path H1 is delivered from the first discharge path H1 to the transport unit 61 by the guide ribs 71a.

At the upstream end of the guide frame 71, as illustrated in FIG. 6, a holding unit 69 is provided along the Y-axis direction, that is, along the medium width direction. In the embodiment, the holding unit 69 is formed as a concave shape. Here, as illustrated in FIG. 3, the line head 34, which is a recording unit, is positioned below the transport unit 61, and in such a configuration, there is a concern that foreign matter generated in the transport unit 61 may fall toward the line head 34 and the recording quality may deteriorate. However, since the holding unit 69 is provided, it is possible to suppress fall of foreign matter generated in the transport path in the transport unit 61, such as paper dust or the like, from the guide frame 71 toward the line head 34, and it is thus possible to suppress deterioration in recording quality.

Next, the second processing unit 120 is provided so as to be slidable in the X-axis direction with respect to the first processing unit 110, and the second processing unit 120 can be caused to slide in the +X direction, as illustrated in FIG. 15, from the state illustrated in FIG. 3, and an opening Cl can be formed between the first processing unit 110 and the second processing unit 120. As a result, when a paper jam occurs in the first processing unit 110 or the second processing unit 120, the jammed medium can be removed.

Here, in the embodiment, the first processing unit 110 is not slidable, and an opening cannot be formed between the first processing unit 110 and the transport unit 61. Therefore, when a paper jam occurs in the first processing unit 110 at a position close to the transport unit 61, or when a paper jam occurs in the transport unit 61, it is difficult to perform paper jam processing.

Therefore, the medium transport device 60 according to the embodiment is provided with the operation unit 80 (to be described later) which is an operation unit that enables manual operation of the transport unit 61, and the driving roller 64 can be manually rotated using the operation unit 80. The rotation direction of the driving roller 64 at this time is the counterclockwise direction in FIG. 3, that is, the direction in which the medium is returned to the first discharge path H1. The operation unit 80 is attachable to and detachable from the device main body 2, and FIG. 8 illustrates a state in which the operation unit 80 is attached.

The operation unit 80 can be attached and detached by opening the first opening/closing body 45 and the second opening/closing body 46 described above. FIG. 8 illustrates a state in which the above-described first path forming member 48 is mounted and the operation unit 80 is mounted. In the embodiment, the operation unit 80 is attachable to and detachable from the device main body 2, but is not limited to this example, as long as the operation unit 80 is located at a position accessible to the user. For example, the operation unit 80 may be attachable to and detachable from the transport unit 61.

The operation unit 80 includes an operation knob 81, which is an input unit to which a user can manually input an operating force, and the driving roller 64 can be rotated in the counterclockwise direction in FIG. 3 by rotating the operation knob 81. In this way, in a state of being engaged with the transport roller pair 62, it is possible to return the jammed medium to the first discharge path H1, and to remove the medium.

A mounting region AS of the operation unit 80 overlaps a mounting region of the second path forming member 49 described above, and the operation unit 80 cannot be mounted in a state in which the second path forming member 49 is mounted. The operation unit 80 is disposed at a position where the operation unit 80 does not interfere with the first path forming member 48 but interferes with the second path forming member 49.

Here, in a mode in which the medium is discharged to the second discharge tray 28 of the in-body discharge portion 30 using the second discharge path H2, the medium transport device 60 and the first processing unit 110 become an obstacle, and the medium transport device 60 and the first processing unit 110 are not used. Therefore, the operation unit 80 is also unnecessary, and the operation unit 80 can be removed. Since the operation unit 80 is disposed at a position at which the operation unit 80 interferes with the second path forming member 49, the second path forming member 49 forming the second discharge path H2 is attached using a space secured by removing the operation unit 80. Such a configuration eliminates the need to secure a space for simultaneously mounting the second path forming member 49 and the operation unit 80, making it possible to suppress an increase in device size.

Hereinafter, the configuration of the operation unit 80 will be described in detail.

In FIG. 7, the operation unit 80 is provided with a first support member 83, a second support member 84, and a support frame 93, and these members constitute a base. The operation knob 81 and the toothed gears 86 and 87 are rotatably supported by the first support member 83. Toothed gears 88 and 89 and a switching gear 90 are rotatably supported by the second support member 84 and the support frame 93. Further, the second support member 84 supports the support frame 93. The support frame 93 rotatably supports a rotary lever 91.

An arrow 81a indicating a rotation direction is marked on the operation knob 81, and further, an arrow 83a indicating the rotation direction of the operation knob 81 is marked on the first support member 83. Thus, the user can easily ascertain an operation direction of the operation knob 81.

A toothed gear 85 is a toothed gear that rotates coaxially with the operation knob 81, and meshes with the toothed gear 86. The toothed gear 87 meshes with the toothed gear 86, and the toothed gear 88 meshes with the toothed gear 87. The toothed gear 89 is integrally provided on the toothed gear 88, and the toothed gear 89 meshes with the switching gear 90. Thus, when the operation knob 81 is rotated, the switching gear 90 is configured to rotate.

As illustrated in FIG. 5, a first toothed gear 66 and a second toothed gear 67 are attached to a shaft end of a rotary shaft 63 of the driving roller 64. As illustrated in FIG. 10, the power of the driving motor 59 (see FIG. 3) is transmitted to the first toothed gear 66 via a power relay portion 58, thus causing the driving roller 64 to rotate (the clockwise direction in FIG. 3).

The switching gear 90 described above is configured to mesh with the second toothed gear 67. The switching gear 90 is configured to be displaceable between a coupling position at which the switching gear 90 is coupled to and meshes with the second toothed gear 67, and a separation position at which the switching gear 90 is spaced apart from the second toothed gear 67. When the switching gear 90 is at the coupling position, a switching unit 82 is in a transmission state in which the operating force input by the operation knob 81 is transmitted to the driving roller 64. When the switching gear 90 is at the separation position, the switching unit 82 is in a decoupled state in which the operating force input by the operation knob 81 is not transmitted to the driving roller 64. FIG. 10 illustrates a state in which the switching gear 90 is at the separation position being spaced apart from the second toothed gear 67, and the switching unit 82 is in the decoupled state.

The switching gear 90 is located at the coupling position in a state in which the second opening/closing body 46 is open, and is displaced from the coupling position to the separation position when the second opening/closing body 46 is closed from this state. Then, when the second opening/closing body 46 is opened from this state, the switching gear 90 is displaced from the separation position to the coupling position.

In FIG. 7, the operation unit 80 is provided with the switching unit 82. The switching unit 82 is provided with the switching gear 90, the rotary lever 91, and a compression coil spring 94.

The switching gear 90 is integrally provided with a cylindrical portion 90a and a flange portion 90b, and is provided to be slidable with respect to a slide shaft 97 (see FIG. 12) extending in the Y-axis direction. One end of the slide shaft 97 is supported by the second support member 84, and the other end of the slide shaft 93 is supported by the support frame 93. The switching gear 90 is displaced between the separation position (see FIG. 12) and the coupling position (see FIG. 13) by sliding in the Y-axis direction.

The rotary lever 91 is provided to be rotatable with respect to a shaft 92 extending in the Z-axis direction. The shaft 92 is a shaft supported by the support frame 93. The rotary lever 91 is provided with a first arm portion 91b and a second arm portion 91c extending from the shaft 92, and a pressed portion 91b is formed at the first arm portion 91a. The pressed portion 91a is a portion that is pressed by the second opening/closing body 46 (see FIG. 10).

The second arm portion 91c is engaged with the flange portion 90b formed integrally with the switching gear 90, and displaces the flange portion 90b, that is, the switching gear 90, in the +Y direction in accordance with the rotation of the rotary lever 91.

In FIG. 7, the compression coil spring 94 is provided between the support frame 93 and the flange portion 90b, and the flange portion 90b, namely, the switching gear 90, and the second arm portion 91c of the rotary lever 91 are pressed in the −Y direction by the compression coil spring 94.

Since the switching unit 82 is configured as described above, when the second opening/closing body 46 is closed, the pressed portion 91a is pressed by the second opening/closing body 46, as illustrated in FIG. 10. In this way, the second arm portion 91c of the rotary lever 91 displaces the flange portion 90b, namely, the switching gear 90, in the +Y direction in resistance to a pressing force of the compression coil spring 94, and the switching unit 82 is caused to be in a state in which the switching gear 90 is spaced apart from the second toothed gear 67 in the +Y direction (the separation position of the switching gear 90), that is, is caused to be in the decoupled state, as illustrated in FIG. 12.

When the second opening/closing body 46 is opened from this state, the flange portion 90b, namely, the switching gear 90, is displaced in the −Y direction by the pressing force of the compression coil spring 94, and the switching unit 82 is caused to be in a state in which the switching gear 90 is coupled to the second toothed gear 67 (the coupling position of the switching gear 90), that is, is caused to be in the transmission state, as illustrated in FIG. 13.

By opening the second opening/closing body 46 in this way, the rotation of the operation knob 81 is transmitted to the second toothed gear 67, and by rotating the operation knob 81, the driving roller 64 can be rotated.

Note that, as illustrated in FIG. 14, a one-way clutch 98 is provided between the rotary shaft 81b of the operation knob 81 and the operation knob 81, so that the rotation of the operation knob 81 is not transmitted to the rotary shaft 81b even if the operation knob 81 is rotated in the opposite direction to the arrow 81a illustrated in FIG. 7. In other words, the driving roller 64 is configured not to rotate in the clockwise direction in FIG. 3 as a result of the rotation of the operation knob 81.

As illustrated in FIG. 8 and FIG. 9, the operation unit 80 described above is fixed by screws to a first frame 100 and a second frame 101 constituting the device main body 2. More specifically, the first frame 100 includes a frame surface parallel to the X-Z plane. Two positioning holes 100b are formed in the first frame 100. As illustrated in FIG. 12 and FIG. 13, two positioning pins 96 are provided on the operation unit 80 so as to protrude from the second support member 84 in the −Y direction, and the two positioning pins 96 are inserted into the two positioning holes 100b illustrated in FIG. 9 to regulate the position of the operation unit 80 with respect to the first frame 100.

A screw hole 100a is formed in the first frame 100, and the first support member 83 of the operation unit 80 is fixed to the first frame 100 by a screw 104. A screw insertion hole 83b formed in the first support member 83 is a hole through which the screw 104 is inserted.

Next, the second frame 101 includes a first bent portion 101a and a second bent portion 101b. The first bent portion 101a and the second bent portion 101b are bent portions forming a frame surface parallel to the Y-Z plane, and the support frame 93 of the operation unit 80 is disposed between the first bent portion 101a and the second bent portion 101b.

A screw hole 101c is formed in the first bent portion 101a, and a screw hole 101d is formed in the second bent portion 101b. Then, the support frame 93 of the operation unit 80 is fixed to the first bent portion 101a by a screw 102 and is fixed to the second bent portion 101b by a screw 103. A screw insertion hole 93a formed in the support frame 93 is a hole through which the screw 102 is inserted, and a screw insertion hole 93b formed in the support frame 93 is a hole through which the screw 103 is inserted.

Here, when the support frame 93 is disposed between the first bent portion 101a and the second bent portion 101b, it is necessary for the support frame 93 to pass over the second bent portion 101b. At this time, the toothed gear 86, the first support member 83, the operation knob 81, and the like are located at positions at which these interfere with an upper portion 2a of the opening when the second opening/closing body 46 is opened, and these are an obstacle to the operation.

Therefore, in the operation unit 80 according to the embodiment, the first support member 83 is configured to be rotatable relative to the second support member 84. In FIG. 11A and FIG. 11B, a reference sign 95 denotes a coupling shaft that couples the first support member 83 and the second support member 84 so that the first support member 83 and the second support member 84 are rotatable relative to each other. The coupling shaft 95 is also a rotary shaft of the toothed gear 87.

FIG. 11A illustrates a state of the first support member 83 and the second support member 84 when the operation unit 80 is attached to the device main body 2. In this state, among the constituent elements of the operation unit 80, the upper end portion of the toothed gear 86 is the portion located furthest in the +Z direction, and the upper end portion of the operation knob 81 is the portion located next in the +Z direction. The position X1 is a position of the upper end portion of the toothed gear 86 in the Z-axis direction, in the state illustrated in FIG. 11A.

In contrast, FIG. 11B illustrates a state in which the first support member 83 has been rotated in the −Z direction from the state illustrated in FIG. 11A. A position X2 is a position of the upper end portion of the toothed gear 86 in the Z-axis direction. in the state illustrated in FIG. 11B.

By rotating the first support member 83 relative to the second support member 84 in this manner, the position of the upper end portion of the toothed gear 86 in the Z-axis direction can be lowered. As a result, interference between the upper portion 2a (see FIG. 9) of the opening and the operation unit 80 when the second opening/closing body 46 is opened can be prevented, and the support frame 93 can be disposed between the first bent portion 101a and the second bent portion 101b. As a result, the region in the Z-axis direction necessary for attaching and detaching the operation unit 80 can be reduced, and thus the dimension of the device main body 2 in the Z-axis direction can be reduced.

As described above, the medium transport device 60 according to the embodiment includes the transport unit 61 that is positioned between the first discharge path H1 of the printer 1 and the first processing unit 110 that performs the first processing on the medium discharged from the first discharge path H1 to the in-body discharge portion 30, and with the operation unit 80 that is the operation unit enabling manual operation of the transport unit 61. Accordingly, it is possible to move the medium that is jammed in a state of being engaged with the transport unit 61, and the paper jam processing can be appropriately performed.

This effect can be obtained both in a case in which the first processing unit 110 is slidable and a case in which the first processing unit 110 is not slidable. In particular, in the configuration in which the first processing unit 110 is not slidable and an opening cannot be formed between the first processing unit 101 and the conveyance section 61, as in the embodiment, the paper jam processing can be appropriately performed.

Further, in the embodiment, the transport portion 61 is provided with the driving roller 64, which is the rotating body that transports the medium by being rotated by the power of the driving motor 59, and the operation unit 80 includes the operation knob 81, which is the input unit to which the operating force can be manually input, and the switching unit 82, which can switch between the transmission state in which the operating force is transmitted to the driving roller 64 and the decoupled state in which the operating force is not transmitted to the driving roller 64. Then, when the driving roller 64 is driven by the power of the driving motor 59, the switching unit 82 is in the decoupled state illustrated in FIG. 12. In this way, when the driving roller 64 is driven by the power of the driving motor 59, the power of the driving motor 59 is not transmitted to the operation knob 81. As a result, when the driving motor 59 drives the driving roller 64, the operation knob 81 does not become a load, the transport unit 61 can be appropriately driven by the driving motor 59, and noise and wear of components can also be suppressed.

However, the present disclosure is not limited to such a configuration, and it is also possible to adopt a configuration in which the switching unit 82 is omitted, and a driving force is constantly transmitted to the operation knob 81 when the driving roller 64 is driven by the power of the driving motor 59.

In addition, in the embodiment, the operation unit 80 further includes the first support member 83 that is a first support portion supporting the operation knob 81, and the second support member 84 that is a second support portion supporting the switching unit 82, and the first support member 83 and the second support member 84 are rotatable relative to each other. In this way, when the operation unit 80 is passed through a space through which it is difficult for the operation unit 80 to pass when attaching the operation unit 80 as described above, such as a narrow space or a space with an obstacle, the operation unit 80 can be passed through, and the operation unit 80 can thus be attached.

However, the present disclosure is not limited to such a configuration, and a configuration may be adopted in which the first support member 83 and the second support member 84 are not rotatable relative to each other.

Further, in the embodiment, the driving roller 64 transports the medium downstream in the transport direction by rotating in a first rotation direction (the clockwise direction in FIG. 3) and transports the medium upstream in the transport direction by rotating in a second rotation direction (the counterclockwise direction in FIG. 3) opposite to the first rotation direction, and when the operating force is input to the operation knob 81, as described with reference to FIG. 14, the driving roller 64 can rotate only in the second rotation direction. With such a configuration, the following operational effects are obtained.

In other words, when the medium jammed in the state of being engaged with the transport unit 61 is transported from the transport unit 61 in the downstream direction, that is, toward the first processing unit 110, there is a concern that it may become impossible to take out the medium. However, when the operating force is input to the operation knob 81 as described above, since the operation knob 81 can only rotate in the second rotation direction, that is, in the direction in which the medium is transported upstream from the transport unit 61, it is possible to suppress the occurrence of a problem in which the jammed medium is transported toward the first processing unit 110 and cannot be taken out.

However, the present disclosure is not limited to such a configuration, and a configuration may be adopted in which the driving roller 64 can rotate in either the first rotation direction or the second rotation direction in accordance with the rotation direction of the operation knob 81.

Further, although the one-way clutch 98 (see FIG. 14) is provided between the rotary shaft 81b of the operation knob 81 and the operation knob 81 in the embodiment, the one-way clutch 98 may be provided at any position as long as the driving roller 64 can rotate only in the second rotation direction when the operating force is input to the operation knob 81, and may be provided at an appropriate position in a power transmission path from the toothed gear 85 to the switching gear 90. Further, a unit for enabling the driving roller 64 to rotate only in the second rotation direction when the operating force is input to the operation knob 81 is not limited to the one-way clutch 98, and may be another unit, such as a planetary gear mechanism.

Further, in the embodiment, the medium transport device 60 is provided with the unit mounting portion 73 to which the first processing unit 110 is mounted, and the unit mounting portion 73 can further mount the second processing unit 120, which is the unit positioned downstream of the first processing unit 110 in the transport direction and which performs the second processing on the medium received from the first processing unit 110. As a result, it is possible to increase the types of processing performed on the medium.

Further, in the embodiment, the first processing performed on the medium by the first processing unit 110 is the processing of punching the medium, and the second processing performed on the medium by the second processing unit 120 is the processing of binding the medium.

Further, in the embodiment, the operation unit 80 is attachable and detachable. Thus, when the operation unit 80 is not mounted, the mounting space of the operation unit 80 can be effectively utilized.

However, the present disclosure is not limited to such a configuration, and the operation unit 80 may be provided in a fixed manner.

Further, in the embodiment, the printer 1 is provided with the first opening/closing body 45 and the second opening/closing body 46, which are provided to be openable and closable with respect to the device main body 2 including the first discharge path H1. The first opening/closing body 45 and the second opening/closing body 46 are opened when attaching or detaching the first path forming member 48, that is, when accessing the first discharge path H1, and the operation unit 80 is exposed by opening the first opening/closing body 45 and the second opening/closing body 46. With such a configuration, by opening the first opening/closing body 45 and the second opening/closing body 46, it is possible to input the operating force to the operation knob 81 and to access the first discharge path H1, and convenience for the user is improved.

In the embodiment, there are the two opening/closing bodies, namely, the first opening/closing body 45 and the second opening/closing body 46, but there may be one opening/closing body, that is, a configuration may be adopted in which the operation unit 80 is exposed by opening the first opening/closing body 45. Alternatively, a configuration may be adopted in which the operation unit 80 is exposed by opening three or more opening/closing bodies.

In the embodiment, the switching unit 82 includes the pressed portion 91a that can be pressed by the second opening/closing body 46, and when the second opening/closing body 46 is in the closed state, pressed portion 91a is pressed by the second opening/closing body 46, thus causing the switching unit 82 to be in the decoupled state. When the second opening/closing body 46 is in the open state, the pressed portion 91a is not pressed by the second opening/closing body 46, thus causing the switching unit 82 to be in the transmission state. In other words, since the state of the switching unit 82 is switched in conjunction with the opening and closing of the second opening/closing body 46, it is not necessary for the user to switch the state of the switching unit 82 by himself or herself, and convenience for the user is improved.

However, the present disclosure is not limited to such a configuration, and a configuration may be adopted in which the user manually switches the state of the switching unit 82. Alternatively, a configuration may be adopted in which the state of the switching unit 82 may be switched using an actuator, such as a solenoid. In this case, a configuration may be adopted in which the user switches the state of the switching unit 82 via an operation panel (not illustrated) of the printer 1.

Further, in the embodiment, the switching unit 82 includes the switching gear 90. The switching gear 90 is positioned at the coupling position at which the switching gear 90 is coupled to the second toothed gear 67 that rotates coaxially with the driving roller 64 in the transmission state (refer to FIG. 13), and is positioned at the separation position at which the switching gear 90 is spaced apart from the second toothed gear 67 in the decoupled state (refer to FIG. 12). Further, in the embodiment, the switching unit 82 is a member including the pressed portion 91a, and is provided with the rotary lever 91 as a displacement portion that displaces the switching gear 90 from the coupling position to the separation position, and with the compression coil spring 94 as a pressing portion that presses the switching gear 90 toward the coupling position. Thus, the switching unit 82 can be configured with a simple mechanism.

Note that, in the embodiment, the switching gear 90 moves between the coupling position and the separation position by being displaced along a rotational axis line direction, but the present disclosure is not limited to this configuration. For example, the switching gear 90 may be configured to move between the coupling position and the separation position by being displaced along a radial direction.

Further, in the embodiment, the line head 34 of the printer 1 performs recording by ejecting the ink, which is an example of a liquid, onto the medium. Here, in a configuration in which the recording is performed by ejecting the ink, which is an example of the liquid, onto the medium, the medium is easily deformed as a result of the ink being ejected onto the medium, and thus a jam is likely to occur. However, since the operation unit 80 is provided that enables manual operation of the transport unit 61, it is possible to move the jammed medium, and it is possible to appropriately perform paper jam processing.

The present disclosure is not intended to be limited to the above-described embodiment, and many variations are possible within the scope of the present disclosure as described in the appended claims. It goes without saying that such variations also fall within the scope of the present disclosure.
