The present application is based on, and claims priority from JP Application Serial Number 2021-170783, filed Oct. 19, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a medium transport device and a recording apparatus.
In the related art, various configurations such as a recording apparatus have been used as a medium transport device that transports a medium. Among them, there is a medium transport device having an outer door and an inner door in order to cover the inside of the device main body and to enable access to the inside of the device body as needed. For example, JP-A-2002-356244 discloses a sheet transport device including an outer door section attached to a device main body and an inner door section attached to the outer door section.
In a medium transport device having an outer door and an inner door, it is desirable to variously change the state according to the type of work performed by a worker, such as when the outer door and the inner door are closed, when the outer door is opened and the inner door is closed, when the outer door is opened and the inner door is removed, or when the outer door and the inner door are opened. Here, in a configuration in which an inner door is attached to an outer door as in the sheet transport device of JP-A-2002-356244, it is sometimes difficult to close the inner door while the outer door is open. In addition, when the position of an outer hinge, which is the pivot axis of the outer door, and the position of an inner hinge, which is the pivot axis of the inner door, are separated from each other, then the device tends to be larger, so it is often desirable that the position of the outer hinge and the position of the inner hinge be near each other.
In order to overcome the above-described problems, a medium transport device according to the disclosure includes a device main body having a transport path for transporting a medium, an outer door, an inner door disposed with respect to the device main body to the inside of the outer door, an outer hinge that openably and closably attaches the outer door to the device main body, and an inner hinge that openably and closably attaches the inner door to the device main body, wherein a pivot axis of the outer hinge and a pivot axis of the inner hinge both extend in a first direction and the outer hinge and the inner hinge overlap when viewed from a direction intersecting an outer door surface of the outer door in a closed state.
The present disclosure will be described in general terms.
A medium transport device according to a first aspect includes a device main body having a transport path for transporting a medium, an outer door, an inner door disposed with respect to the device main body to the inside of the outer door, an outer hinge that openably and closably attaches the outer door to the device main body, and an inner hinge that openably and closably attaches the inner door to the device main body, wherein a pivot axis of the outer hinge and a pivot axis of the inner hinge both extend in a first direction and the outer hinge and the inner hinge overlap when viewed from a direction intersecting an outer door surface of the outer door in a closed state.
According to this aspect, the outer hinge and the inner hinge overlap when viewed from a direction intersecting an outer door surface of the outer door in a closed state. That is, since the position of the outer hinge and the position of the inner hinge are close to each other, the device can be miniaturized. Further, since both the outer door and the inner door are attached to the device main body, the outer door and the inner door can be brought into various states such as, in addition to a state in which the outer door and the inner door are closed and a state in which the outer door and the inner door are open, the inner door being removed while the outer door is in an open state, and a state in which the inner door is closed while the outer door is in an open state.
In a medium transport device according to a second aspect, with respect to the first aspect, the device main body has a fixing surface to which is fixed the inner hinge and the fixing surface is arranged so as to be inclined at an acute angle with respect to the outer door surface of the outer door in the closed state.
In general, when the position of the outer hinge and the position of the inner hinge are close to each other, it is difficult to remove the inner door while the outer door is attached. This is because the outer door becomes an obstacle and it is difficult to access the inner hinge. However, according to this aspect, the fixing surface is disposed so as to be inclined at an acute angle with respect to the outer door surface of the outer door in the closed state. For this reason, it is possible to suppress the likelihood of the outer door becoming an obstacle and making it difficult to access the inner hinge, and it is possible to easily remove the inner door in a state where the outer door is open.
In a medium transport device according to a third aspect, with respect to the first aspect, the device main body has a fixing surface for fixing the inner hinge by a fixing member and the fixing surface is arranged so that when the inner hinge is fixed by the fixing member, the fixing member does not interfere with the outer door in an open state.
According to this aspect, the fixing surface is arranged so that when the inner hinge is fixed by the fixing member, the fixing member does not interfere with the outer door in an open state. For this reason, it is possible to suppress a situation in which it is difficult to fix the inner hinge to the fixing surface due to the fixing member interfering with the outer door, and it is possible to easily remove the inner door in a state in which the outer door is open.
In a medium transport device according to a fourth aspect, with respect to any one of the first aspect to the third aspect, a regulation section is provided that regulates an opening angle of the outer door.
According to this aspect, the regulation section is provided that regulates the opening angle of the outer door. For this reason, it is possible to suppress the outer door from colliding with an external device, an external wall, or the like because the outer door is excessively opened.
In a medium transport device according to a fifth aspect, with respect to any one of the first aspect to the fourth aspect, the inner door in a closed state, together with the device main body, constitutes at least a portion of a first transport path of the transport path.
According to this aspect, the inner door in the closed state constitutes at least a portion of the first transport path together with the device main body. Since the inner door also serves the dual role of at least a portion of the first transport path, the apparatus configuration can be simplified. In addition, by opening the inner door together with the outer door, it is possible to easily remove the medium in a case where a transport failure of the medium occurs in the first transport path.
In a medium transport device according to a sixth aspect, with respect to the fifth aspect, the inner hinge is disposed outside a medium transport region of the first transport path, with respect to a width direction, which intersects a transport direction of the medium.
According to this aspect, the inner hinge is disposed to the outside of the medium transport region of the first transport path, with respect to a width direction. Therefore, it is possible to suppress the medium that is being transported in the first transport path, from being interfered with by the inner hinge.
In a medium transport device according to a seventh aspect, with respect to any one of the first aspect to the sixth aspect, the inner door in a closed state, together with the outer door in the closed state, constitutes at least a portion of a second transport path of the transport path.
According to this aspect, the inner door in the closed state constitutes at least a portion of the second transport path together with the outer door in the closed state. Since the inner door also serves the dual role of at least a portion of the second transport path, the apparatus configuration can be simplified. In addition, by opening the outer door, it is possible to easily remove the medium in a case where a transport failure of the medium occurs in the second transport path.
In a medium transport device according to an eighth aspect, with respect to any one of the first aspect to the seventh aspect, the inner door has an attachment surface for the inner hinge, the attachment surface, while the inner door is in the closed state, intersecting the outer door surface of the outer door in the closed state and the inner hinge is disposed so that, when viewed from a direction facing the attachment surface for the inner hinge, the inner hinge does not protrude from the attachment surface for the inner hinge.
According to this aspect, the inner hinge is disposed so that, when viewed from a direction facing the attachment surface for the inner hinge, the inner hinge does not protrude from the attachment surface for the inner hinge. Therefore, since interference of the inner hinge with the device main body and the outer door can be suppressed, the inner door can be arranged close to the device main body and the outer door, and the apparatus can be miniaturized.
In a medium transport device according to a ninth aspect, with respect to any one of the first aspect to the eighth aspect, the device main body includes a holding section configured to hold a first unit that is attachable and detachable after the inner door is removed, and the holding section is disposed, with the inner door in the closed state as a reference, on the opposite side than the outer door in the closed state.
According to this aspect, the device main body includes the holding section that holds the first unit that is attachable and detachable after removing the inner door. Therefore, various first units can be attached to the device main body. Although the holding section is, with reference to the inner door in the closed state, disposed on the opposite side than the outer door in the closed state, when the first unit is to be attached or detached, the inner door can be easily removed while the outer door is in the open state.
A medium transport device according to a tenth aspect, with respect to the ninth aspect, includes the first unit.
According to this aspect, the first unit is provided. Therefore, it is possible to perform various processes on the medium transported to the first unit.

According to this aspect, the first unit is configured to be connectable to the second unit and is a transport unit that transports the medium to the second unit. Therefore, it is possible to perform various processes on the medium transported to the second unit via the transport unit.
A medium transport device according to a twelfth aspect, with respect to the eleventh aspect, includes the second unit, wherein the second unit is configured to transport the medium to an external apparatus.
According to this aspect, it is possible to transport the medium to an external device. Therefore, various processes can be performed on the medium transported to the external apparatus.
A recording apparatus according to a thirteenth aspect includes the medium transport device according to any one of the first aspect to the eleventh aspect and a recording unit that performs recording on the medium.
According to this aspect, in the recording apparatus having the outer door and the inner door, it is possible to bring the outer door and the inner door into various states, such as bringing the inner door into a closed state in a state where the outer door is opened, while suppressing an increase in size of the apparatus.
Hereinafter, as an embodiment, a specific example of a recording apparatus as an example of a medium transport device according to the disclosure will be described.
As shown in
The device main body 12 includes a case 11 serving as an outer shell and a plurality of frames 60 shown in
As shown in
In addition, the device main body 12 is provided with an inner door 40, which is a door that opens and closes, at the inner side, which is to the + X direction side of the outer door 30, that is, at the inner side of the outer opening 12A. As shown in
As shown in
The transport section 20 includes a transport belt 22 wound around two pulleys 21, a registration roller pair 23 that performs skew correction or the like of the sheet P, pairs of transport rollers 24 that transport the sheets P, a plurality of flaps 25 that switch the paths through which the sheets P are transported, and a medium width detection unit 26 that detects the Y direction width of the sheets P. A transport path T3 toward the discharge section 13 and a inversion path T4 for reversing the front and back of sheets P are provided at the downstream side of the transport belt 22 in the transport path T. Note that when the inner door 40 in the closed state as shown in
The transport path T3 is provided with a discharge port E1 and a discharge port E2 through which sheets P are discharged. However, in the state of
In addition, the device main body 12 is provided with an ink tank 27, which stores the ink Q, and a control section 29, which is a control circuit board which controls the operation of each section of the printer 10. The line head 28 is at a position downstream from the medium width detection unit 26 in the transport direction of the sheets P and at a position facing the transport belt 22. The line head 28 is an example of a recording section, and performs recording by ejecting ink Q supplied from the ink tank 27 onto sheets P fed from the feeding section 50.
The control section 29 is configured to include a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and a storage, none of which are shown, and controls transport of the sheets P in the printer 10 and operations of sections including the line head 28, the transport section 20, and the feeding section 50.
How the outer door 30 and the inner door 40 are attached to the device main body 12 will be described next with reference to
Here, as shown in
As shown in
Here, as shown in
In summary, the printer 10 of the present embodiment includes the device main body 12 having the transport path T for transporting the sheet P, the outer door 30, the inner door 40 disposed to the inside of the outer door 30 with respect to the device main body 12, the outer hinge 31 for openably and closably attaching the outer door 30 to the device main body 12, and the inner hinge 41 for openably and closably attaching the inner door 40 to the device main body 12. The pivot axis 15 of the outer hinge 31 and the pivot axis 5 of the inner hinge 41 both extend in the Z direction as a first direction, and the outer hinges 31 and the inner hinge 41 are disposed at positions overlapping each other when viewed from the X direction, which is a direction intersecting the outer door surface 30B of the outer door 30 in the closed state.
In this way, by arranging the outer hinge 31 and the inner hinge 41 at positions that overlap when viewed from the X direction, the position of the outer hinge 31 and the position of the inner hinge 41 can be close to each other, so that the device can be made smaller. Further, since both the outer door 30 and the inner door 40 are attached to the device main body 12, the outer door 30 and the inner door 40 can be brought into various states such as, in addition to a state in which the outer door 30 and the inner door 40 are closed and a state in which the outer door 30 and the inner door 40 are open, the inner door 40 being removed while the outer door 30 is in an open state, and a state in which the inner door 40 is closed while the outer door 30 is in an open state. Note that “the outer hinges 31 and the inner hinge 41 are arranged at positions overlapping each other when viewed from the X direction” includes not only an arrangement in which the outer hinges 31 and the inner hinge 41 completely overlap each other when viewed from the X direction but also an arrangement in which the outer hinges 31 and the inner hinge 41 only partially overlap each other when viewed from the X direction.
Here, from another point of view, in addition to being a medium transport device, the printer 10 according to the embodiment is a recording apparatus including the line head 28 that performs recording on sheets P. Therefore, in the recording apparatus having the outer door 30 and the inner door 40, it is possible to bring the outer door 30 and the inner door 40 into various states, such as bringing the inner door 40 into a closed state in a state where the outer door 30 is opened, while suppressing an increase in size of the apparatus.
Further, as described above, the device main body 12 has the fixing surface 60A for fixing the inner hinge 41, and the fixing surface 60A is arranged to be inclined at an acute angle with respect to the outer door surface 30B of the outer door 30 in the closed state. In general, when the position of the outer hinge 31 and the position of the inner hinge 41 are close to each other, it is difficult to remove the inner door 40 while the outer door 30 is attached. This is because the outer door 30 becomes an obstacle and it is difficult to access the inner hinge 41. However, in the printer 10 of the present embodiment, the fixing surface 60A is disposed so as to be inclined at an acute angle with respect to the outer door surface 30B of the outer door 30 in the closed state. For this reason, it is possible to suppress the likelihood of the outer door 30 becoming an obstacle and making it difficult to access the inner hinge 41, and it is possible to easily remove the inner door 40 in a state where the outer door 30 is open.
Further, from another viewpoint, as shown in
Hereinafter, the arrangement and configuration of the outer door 30 and the inner door 40 will be described in more detail with reference to
Using a different expression, the inner door 40 has the attachment surface 40C of the inner hinge 41, which is the X-Z plane that, when the inner door 40 is in the closed state, intersects with the Y―Z plane, which is the outer door surface 30C of the outer door 30 in the closed state. As shown in
The printer 10 of this embodiment can use sheets P of various sizes, but the position that corresponds to the end in the -Y direction, which is the widthwise direction of the sheet P, when the largest sheet P is used is the maximum medium width direction end position L1 indicated by the alternate long and short dash line in
Using a different expression, the inner hinge 41 is disposed to the outside of the medium transport region in the transport path T3, as the first transport path, and in the inversion path T4, as the second transport path, with respect to the widthwise direction, which intersects the transport direction of the sheet P. For this reason, in the printer 10 of the present embodiment, it is possible to suppress sheets P being transported in the transport path T3 and in the inversion path T4 from interfering with the inner hinge 41. It should be noted that in the printer 10 according to this embodiment, the inner hinge 41 is disposed to the outside of the medium transport region in the widthwise direction with respect to both the transport path T3 and the inversion path T4. However, the present disclosure is not limited to such a configuration, and for example, a configuration may be adopted in which the inner hinge 41 is disposed to the outside of the medium transport region in the width direction of one of the transport path T3 and the inversion path T4 . However, it is desirable to adopt a configuration in which the inner hinge 41 is disposed to the outside of the medium transport region in the width direction with respect to at least the transport path T3.
In the printer 10 of the present embodiment, the opening angle of the outer door 30 is restricted.
As shown in
In the printer 10 of the present embodiment, the outer door 30 and the inner door 40 are configured and arranged as described above. Since the outer door 30 and the inner door 40 are configured and arranged as described above, the inner door 40 in the closed state configures together with the device main body 12 at least a portion of the transport path T3, which is a first transport path among the transport path of the sheets P. Since the inner door 40 has a dual role as at least a portion of the first transport path, the apparatus configuration can be simplified. In addition, by opening the outer door 30, or opening the inner door 40 together with the outer door 30, it is possible to easily remove a sheet P in a case where a transport failure of the sheet P occurs in the transport path T3, which is a first transport path.
The inner door 40 in the closed state, along with the outer door 30 in the closed state, configures at least a portion of the inversion path T4, which is a second transport path of the transport path of the sheet P. As described above, since the inner door 40 also serves the dual role as at least a portion of the second transport path, the apparatus configuration can be simplified. In addition, by opening the outer door 30, it is possible to easily remove a sheet P in a case where a transport failure of the sheet P occurs in the inversion path T4, which is a second transport path.
Various units and external devices can be connected to the printer 10 of the present embodiment. Here, among the various units, there is a first unit configured to be attached to and detached from the inner opening 12B side by removing the inner door 40 from the device main body 12, and a second unit which can be connected to the first unit from outside the device main body 12 without detaching the inner door 40 from the device main body 12. Examples of the first unit include a medium transport unit 100 (to be described later), a switching unit of the sheet P transport path, a sensor unit, and the like, and examples of the second unit include a post-processing unit 70 (to be described later), a relay unit 81, a discharge tray attached separately from the discharge section 13, a stapler (finisher) unit, and the like. Further, as will be described later, examples of the external device include a stapler device. Examples of attachment of various units and external devices of the printer 10 according to this embodiment will be described in more detail below with reference to
As shown in
As shown in
For example, as shown in
In the printer 10 of the embodiment, since the Y direction lengths of the first discharge port guide section 90 and the medium transport unit 100 are longer than the Y direction length of the inner door 40, the first discharge port guide section 90 cannot be taken out and the medium transport unit 100 cannot be attached unless the inner door 40 is detached from the device main body 12, but the configuration is not limited to this. The configuration may be one in which the Y direction lengths of the first discharge port guide section 90 and the medium transport unit 100 may be shorter than the Y direction length of the inner door 40, and the first discharge port guide section 90 may be pulled out while the inner door 40 is in an open state and the inner door 40 is still attached to the device main body 12, and the configuration may be one in which the medium transport unit 100 can be attached and detached with the inner door 40 in an open state while the inner door 40 is still attached to the device main body 12.
Here, in the printer 10 of the present embodiment, by mounting the medium transport unit 100, it is possible to guide the discharge direction of the sheet P such that the sheet P transported on the transport path T3 is directed toward the second discharge port E2 and not toward the first discharge port E1. Said in opposite terms, when the sheet P is to be discharged toward the first discharge port E1 instead of the second discharge port E2, then the first discharge port guide section 90 is attached. For example, as shown in
Here, the entire post-processing unit 70 shown in
As described above, the device main body 12 includes the holding section 60B, which holds the first unit that has various configurations, such as the first discharge port guide section 90, and that can be attached and detached by removing the inner door 40. The holding section 60B is disposed on the + X direction side of the inner door 40, that is, with the inner door 40 in the closed state as a reference point, on the opposite side than the outer door 30 in the closed state. In this manner, since the device main body 12 has the holding section 60B for holding the first unit, which can be attached and detached by removing the inner door 40, various first units can be attached to the device main body 12. Although the holding section 60B for the first unit is, with reference to the inner door 40 in the closed state, disposed on the opposite side than the outer door 30 in the closed state, when the first unit is to be attached or detached, the inner door 40 can be easily removed while the outer door 30 is in the open state. In addition, by regarding the printer 10 as one apparatus including the first unit, it is possible to perform various processes on the medium transported to the first unit.
Further, as shown in
As described above, the printer 10 shown in
The relay unit 81 may be used together with the medium transport unit 100 as in the present embodiment, or may be used instead of the medium transport unit 100. Note that the units and external devices are not particularly limited.
Although the embodiments of the present disclosure are based on the above-described configuration, it is of course possible to change or omit a partial configuration without departing from the gist of the present disclosure. For example, the present disclosure includes a configuration in which an external device such as the post-processor device unit 80 is connected to the second unit, and also includes a configuration in which the second unit can execute desired processing without the external device being connected to the second unit.
