The front cover 7a is provided with an operation panel 6 for performing operations for performing various print settings and recording, and for displaying previews of print settings and print images.

The discharge tray 12 can be configured to be switchable between a storage state (FIG. 1) stored in the housing 2 and a protruding state (FIG. 2) protruding forward from the housing 2. 2 that protrudes forward from the recording medium, the recording medium can be received and ejected.
The discharge tray 12 is configured to be switchable between a stored state and a projected state by a motor (not shown).

The medium tray 11 shown in FIG. 2 can store a plurality of media and is detachable from the housing 2. The medium can be sent out from the mounted medium tray 11 toward the recording head 10.
The medium transport path in the printer 1 will be described later.

  As shown in FIG. 2, a medium supply port 9 capable of supplying the medium to a recording head 10 (FIG. 3) is provided in an upper portion of the housing 2. When the downstream side (+ Y side) in the medium transport direction with respect to the recording head 10 is the front of the apparatus and the upstream side (−Y side) is the rear side of the apparatus with respect to the recording head 10, the medium supply port 9 Is provided.

The medium supply port 9 can be covered by the supply port cover 3 as a “first opening / closing body”. The medium supply port 9 has a first state in which the medium supply port 9 is covered by a first rotation shaft 13 located on the rear side (−Y side) of the apparatus with respect to the medium supply port 9 as shown in FIG. It rotates between the second state (FIG. 2 as an example) in which the medium supply port 9 is opened more than the first state (FIG. 1).
By opening the supply port cover 3 as shown in FIG. 2, the medium can be fed to the recording head 10 using the medium supply port 9.
Note that the second state refers to a state in which the medium supply port 9 is more open than the first state. In addition to the state shown in FIG. 2 in which the medium supply port 9 is completely opened, for example, as shown in FIGS. It also includes a state that is slightly open than the state.
The supply port cover 3 is attached to the housing 2 via a displacement member 30 described later. The displacement member 30 will be described later in detail.

  The supply port cover 3 functions as a “medium support section” that supports the medium set in the medium supply port 9 in the second state shown in FIG. Thus, the medium P can be stably supplied from the medium supply port 9.

Further, in the printer 1, the image reading mechanism 4 is provided rotatably with respect to the upper part of the housing 2. That is, the image reading mechanism 4 is a “second opening / closing body” in the printer 1. The image reading mechanism 4 is configured to cover a portion other than the medium supply port 9 in an upper portion of the housing 2 by a second rotation shaft 14 located in front of the apparatus (+ Y side) with respect to the first rotation shaft 13. The supply port cover 3 rotates in the same direction as the supply port cover 3 between a third state (FIG. 1) and a fourth state (FIG. 5) farther from the upper part than the third state. That is, as shown in FIG. 6, the rotation axis S1 of the first rotation shaft 13 and the rotation axis S2 of the second rotation shaft 14 are arranged in parallel.
Note that the fourth state refers to a state in which the third state is open farther from the housing 2 than the third state, and includes a state until completely opened as well as a completely opened state as shown in FIG.
Further, in the present embodiment, the image reading mechanism 4 as the “second opening / closing body” covers the entire upper portion of the housing 2 except for the medium supply port 9, but the “second opening / closing body” is in the third state. In the above, a component that covers at least a part of the upper part of the housing 2 other than the medium supply port 9 may be used.

The second rotation shaft 14 of the image reading mechanism 4 will be described in more detail.
The image reading mechanism 4 is rotatably connected to the housing 2 at connection portions 24 (FIGS. 2 and 6) provided on both sides of the medium supply port 9 in the X-axis direction. As shown in FIG. 6, each of the connecting portions 24 is provided with a second rotating shaft 14. The second rotating shaft 14 is supported by a bearing (not shown) provided on the housing 2 side. Then, the image reading mechanism 4 rotates so as to open and close the upper part of the housing 2.

As shown in FIG. 4, the image reading mechanism 4 includes an apparatus main body 40 having a reading unit 42 (FIG. 3) therein, and an original table cover 5 that can open and close an original table 41 provided on the upper part of the apparatus main body 40. ing. When the platen cover 5 is opened as shown in FIG. 4, the platen 41 is exposed. The document is placed on the document table 41 such that the reading surface faces the document table 41.
As shown in FIG. 3, the document table cover 5 has a rotation shaft 15 immediately in front (+ Y side) of the free end 3 b of the supply port cover 3. In the present embodiment, the front end 3b of the supply port cover 3 and the rear end 5a of the platen cover 5 are provided close to each other, but when the platen cover 5 is opened as shown in FIG. The front end 3b of the mouth cover 3 is provided at an interval so as not to interfere with the rear end 5a of the document table cover 5.

The image reading mechanism 4 is provided such that the apparatus main body 40 enters the housing 2 and the upper surface of the document table cover 5 is flush with the upper surface of the supply port cover 3 in the third state (FIG. 1). ing.
A notch 8 is provided on both sides of the housing 2 as shown in FIG. 5, and when the image reading mechanism 4 is in the closed third state as shown in FIG. 8 so that the side surface 43 of the apparatus body 40 is exposed. Thus, the user can put the hand on the side surface 43 and open the image reading mechanism 4 toward the fourth state.

By the way, as described above, if the leading end 3b of the supply port cover 3 and the rear end 5a of the document table cover 5 are provided close to each other, there is a sense of unity between the supply port cover 3 and the document table cover 5. Appearance and appearance are improved. However, when the image reading mechanism 4 is opened toward the fourth state shown in FIG. 5, the rear end 5 a of the document table cover 5 which is also the rear end of the image reading mechanism 4 interferes with the supply port cover 3. May not open.
If the distance between the front end 3b of the supply port cover 3 and the rear end 5a of the platen cover 5 is increased, the problem of the interference can be avoided. It is difficult to obtain an aesthetic appearance based on this, and the size of the device is also increased.

Here, in order to suppress interference with the supply port cover 3 (first opening / closing body) when the image reading mechanism 4 (second opening / closing body) is opened, the printer 1 sets the third state ( A movement mechanism 25 (FIG. 6) that slides the first rotation shaft 13 upward or in one direction behind the apparatus in conjunction with the rotation from the state shown in FIG. 1 to the fourth state (FIG. 5). .
The moving mechanism 25 of the present embodiment slides the first rotation shaft 13 of the supply port cover 3 in the rear of the apparatus, that is, in the −Y direction.

  The first rotation shaft 13 of the supply port cover 3 is moved in the −Y direction by the movement mechanism 25 in conjunction with the rotation of the image reading mechanism 4 from the third state (FIG. 1) to the fourth state (FIG. 5). The image reading mechanism 4 can be prevented from interfering with the supply port cover 3 when the image reading mechanism 4 is opened. The moving mechanism 25 can be realized by a simple configuration as described below.

■■■ About moving mechanism ■■■
The moving mechanism 25 according to the present embodiment shown in FIGS. 8 to 15 is provided with the first rotation shaft 13 and has a first position D1 (FIG. 11) and a device rearward (−) with respect to the first position D1. A displacement member 30 (see also FIG. 7) displaceable between a second position D2 (FIG. 12) located on the Y side) and the displacement member 30 as shown in FIG. When the first opening / closing body is in the first state and the image reading mechanism 4 (the second opening / closing body) is in the third state, it is located at the first position D1 as shown in FIG. When the second opening / closing member is rotated from the third state in FIG. 1 to the fourth state in FIG. 5, the supply port cover 3 (first opening / closing member) is rotated by the image reading mechanism 4 (second opening / closing member). It is configured to be displaceable from a first position D1 (FIG. 11) to a second position D2 (FIG. 12) by an external force received from the body.
Note that, in FIG. 11 or FIG. 12, the positions indicated by reference numerals D1 and D2 indicate the positions of the first rotation shaft 13 provided on the displacement member 30 at the first position D1 and the second position D2, respectively. .

The moving mechanism 25 will be described more specifically.
As described above, the supply port cover 3 is attached to the housing 2 via the displacement member 30.
FIG. 7 shows a perspective view of the displacement member 30 alone. The displacement member 30 has a first rotation shaft 13. The first rotation shaft 13 is attached to the displacement member 30 on a bearing 3 a (FIG. 9) provided on the supply port cover 3, so that the supply port cover 3 can rotate with respect to the displacement member 30. Then, the displacement member 30 is attached to the casing 2, and the supply port cover 3 is attached to the casing 2 so as to open and close the medium supply port 9.

  As shown in FIG. 7, the displacement member 30 includes guide portions 32 on both sides in the device width direction (X-axis direction). A guide groove 33 (FIG. 9) is provided inside the housing 2. The guide portion 32 (FIG. 7) can be fitted into the guide groove 33 and attached to the housing 2. By being guided along the guide groove 33, the displacement member 30 is slidable in the Y-axis direction.

  As shown in FIG. 1, the displacement member 30 is provided when the supply port cover 3 is in the first state and the image reading mechanism 4 is in the third state, that is, when both the supply port cover 3 and the image reading mechanism 4 are in the housing. When the shutter 2 is in the closed state, as shown in FIGS. 9 and 11, it is located at a first position in front of the apparatus (+ Y side). When the displacement member 30 is located at the first position D1, the first rotation shaft 13 is located inside the housing 2 in the front-rear direction of the device (Y-axis direction) as shown in FIG. .

  When the image reading mechanism 4 (the second opening / closing body) rotates from the third state in FIG. 1 to the fourth state in FIG. 5, that is, when the image reading mechanism 4 is opened, Since the end 5a (the rear end 5a of the document table cover 5) and the front end 3b of the supply port cover 3 are close to each other, the rear end 5a contacts the front end 3b as it is. However, since the first rotation shaft 13 of the supply port cover 3 is provided on the displacement member 30, the image reading mechanism 4 is further opened after the rear end 5a contacts the front end 3b, and the supply port cover 3 is opened. When an external force including a component in the −Y direction is applied, the entire supply port cover 3 including the first rotating shaft 13 can be retracted in the −Y direction. When the displacement member 30 is located at the second position D2, the first rotation shaft 13 is located outside the housing 2 in the front-rear direction of the device (Y-axis direction) as shown in FIG.

  As shown in FIGS. 10 and 12, when the displacement member 30 moves to the second position D <b> 2 and the first rotation shaft 13 moves in the −Y direction, the supply port cover 3 at the rear end 5 a of the image reading mechanism 4. Can interfere with the leading end 3b, and the image reading mechanism 4 can be opened smoothly. Since the supply port cover 3 overlaps the connecting portion 24 (FIGS. 2 and 6) which is a part of the image reading mechanism 4 in the height direction (Z-axis direction), the supply port cover 3 moves in the opening direction of the image reading mechanism 4. When turned, the supply port cover 3 is also pushed up by the image reading mechanism 4 and turned in the opening direction.

  Since the moving mechanism 25 is configured as described above, the supply port cover 3 is moved in conjunction with the rotation of the image reading mechanism 4 from the third state (FIG. 1) to the fourth state (FIG. 5). A mechanism for sliding backward can be formed with a simple configuration and at low cost.

  Incidentally, as shown in FIG. 4, the image reading mechanism 4 can be opened while the original platen cover 5 is open. Also in this case, as shown in FIG. 13, the rear end 5 a contacts the front end 3 b of the supply port cover 3, and the image reading mechanism 4 rotates to the fourth state, so that the −Y direction component is applied to the supply port cover 3. Including external force. Then, the displacement member 30 moves in the -Y direction toward the second position D2.

Subsequently, another configuration of the moving mechanism 25 will be described.
The displacement member 30 attached to the housing 2 is pressed from the second position D2 toward the first position D1. More specifically, as shown in FIG. 8, provided between a spring hook 31 of the displacement member 30 and a housing-side spring hook 35 serving as a “fixing member” fixed inside the housing 2. And a tension spring 34 as a "spring member" for pulling the displacement member 30 from the second position D2 side to the first position D1 side.

  When the displacement member 30 is pressed (pulled) from the second position D2 toward the first position D1, the image reading mechanism 4 (second opening / closing body) is brought into the fourth state (FIGS. 5 and 10). , And FIG. 12) to the third state (FIGS. 1, 9, and 11), the displacement member 30 automatically returns from the second position to the first position D1. Therefore, the supply port cover 3 (the first opening / closing body) is also automatically changed from the second state (for example, FIGS. 5, 10, and 12) to the first state (FIGS. 1, 9, and 11). . Thus, the possibility that the supply port cover 3 remains open can be reduced.

The configuration in which the displacement member 30 is pressed from the second position D2 toward the first position D1 can be easily realized by the above configuration using the tension spring 34.
Note that, for example, a configuration in which a coil spring is provided between the displacement member 30 and the inner wall behind the device of the housing 2 to press the displacement member 30 from the second position D2 toward the first position D1 is also possible. It is.

As shown in FIGS. 2 and 6, the supply port cover 3 (first opening / closing body) is in the first state (FIG. 1) independently of the rotation of the image reading mechanism 4 (second opening / closing body). ) And a second state (FIG. 2). Therefore, when recording is performed by setting a medium in the medium supply port 9, the medium is supported by setting the supply port cover 3 to the second state (FIG. 2) without interlocking with the rotation of the image reading mechanism 4. It can be used as a medium support.
The supply port cover 3 may be provided with a lock mechanism for holding the supply port cover 3 at the opening angle shown in FIGS. 2 and 6.

More specifically, the first feed roller 16 that is rotationally driven by a drive source (not shown) is provided on a roller support member 28 that swings about a swing shaft 28 a, and is stored in the medium tray 11. By rotating in contact with the uppermost medium, the uppermost medium is sent out from the medium tray 11 to the rear side (−Y side) of the apparatus.

  On the downstream side of the first feed roller 16, an intermediate roller 17 is provided, which is rotationally driven by a drive source (not shown). The intermediate roller 17 causes the medium to be curved and inverted, and the apparatus front side (+ Y side). Sent to. Reference numerals 18a, 18b, and 18c denote driven rollers that can be driven and rotated. The medium is nipped by the driven roller 18a and the intermediate roller 17, and is nipped by the driven roller 18b and the intermediate roller 17 to the downstream side. Is sent. The driven roller 18c will be described later.

[Third Embodiment]
In the third embodiment, another example of the moving mechanism will be described with reference to FIGS.
In the present embodiment, the “second opening / closing body” is the document table cover 5 that opens and closes the document table 41 of the image reading mechanism 4 that reads an image of a document, as in the second embodiment.

The moving mechanism 60 according to the present embodiment performs the first rotation in conjunction with the rotation of the platen cover 5 from the third state (FIGS. 1 and 6) to the fourth state (FIGS. 4 and 17). In this configuration, the shaft 13 is slid in one direction above the apparatus (in the + Z direction).
The moving mechanism 60 is provided with a displacement member 61 and a cam member 62 as shown in FIGS. The displacement member 61 is configured to be displaceable between a first position F1 (FIG. 16) and a second position F2 (FIG. 17) located above the apparatus with respect to the first position F1. The positions indicated by reference numerals F1 and F2 indicate the positions of the upper ends of the displacement members 61 at the first position F1 and the second position F2, respectively.

The cam member 62 transmits the rotation of the document table cover 5 from the third state (FIG. 16) to the fourth state (FIG. 17) to the displacement member 61 by changing the movement force in the upward direction (+ Z direction) of the apparatus. Specifically, the cam member 62 is formed as a rotating body that rotates about a rotation shaft 63 whose rotation axis is a direction along the X-axis direction that intersects the displacement direction (Z-axis direction) of the displacement member 61. I have.
The cam member 62 is arranged such that one end thereof can contact a contact portion 65 provided on the rear end side (−Y side) of the document table cover 5 when rotated. The displacement member 61 is arranged so as to be able to contact the lower end portion (61 a) of the displacement member 61 (−Z direction).

As shown in FIG. 17, when the platen cover 5 rotates from the third state to the fourth state, the cam member 62 is pressed by the contact portion 65 and rotates counterclockwise in plan view. Then, by the rotation of the cam member 62, the displacement member 61 is displaced from the first position F1 to a second position F2 above the apparatus. At this time, the upper end 61b of the displacement member 61 contacts the supply port cover 3, and the supply port cover 3 slides upward integrally with the displacement member 61. Thus, the first rotation shaft 13 of the supply port cover 3 can be slid upward.
The supply port cover 3 is attached to the housing 2 via an attachment member 64. The attachment member 64 is attached to the housing 2 with a play that allows the supply port cover 3 to move upward. Has been.

  As described above, the displacement member 61 that can be displaced between the first position F1 and the second position F2 above the first position F1 and the second position of the platen cover 5 (second opening / closing body). And a cam member 62 that converts the rotation from the third state to the fourth state into an upward moving force and transmits the rotation to the displacement member 61. The displacement member 61 includes a supply port cover 3 (first opening / closing body). In the first state, when the platen cover 5 is in the third state (FIG. 16), the platen cover 5 is located at the first position F1 and rotates from the third state to the fourth state. (FIG. 17), the original platen cover 5 (the second platen) is moved by the moving mechanism 60 which comes into contact with the supply port cover 3 and is displaced toward the second position F2 by the moving force received via the cam member 62. In conjunction with the rotation of the opening / closing body from the third state to the fourth state, the first rotating shaft 13 is moved upward. A configuration for sliding in one direction can be easily realized.

  In the present embodiment, a tension spring 66 is provided between the displacement member 61 and the inside of the housing 2, and the displacement member 61 is moved from the second position F2 (FIG. 17) to the first position F1 (FIG. 16). ), That is, pressed in the −Z direction.

  The printer 1 as an example of the recording apparatus according to the present invention has been described above. However, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention described in the claims. Yes, they are also included in the scope of the present invention.

<<<< Another configuration that can avoid interference between the platen cover and the supply port cover >>>>
Interference between the platen cover 5 and the supply port cover 3 can be avoided by adopting a configuration as described below.
For example, as shown in FIG. 18, a shaft hole 71 provided on the housing 2 side and serving as a bearing for receiving the rotation shaft 15 of the document table cover 5 is formed as a long hole elongated in the height direction (Z-axis direction). I do. When the platen cover 5 is closed (the state of the platen cover 5 indicated by a solid line in FIG. 18), the rotating shaft 15 is provided below the shaft hole 71.
When the shaft hole 71 is formed in a long hole, the document table cover 5 can be opened while the rotating shaft 15 is positioned above the shaft hole 71 as in the document table cover 5 indicated by a dotted line in FIG. Therefore, even when the supply port cover 3 is closed, interference between the document table cover 5 and the supply port cover 3 can be avoided.

As shown in FIG. 19, a long shaft hole 72 which is provided on the housing 2 side and is a bearing for receiving the rotation shaft 15 of the document table cover 5 is inclined in a direction ascending toward the front of the apparatus. It may be provided. In a state where the platen cover 5 is closed (the state of the platen cover 5 indicated by a solid line in FIG. 19), the rotating shaft 15 is positioned below the shaft hole 72 and at the rear of the apparatus (−Y side). Is provided.
When the shaft hole 72 is formed in a long hole inclined in a direction ascending toward the front of the apparatus, the rotating shaft 15 is positioned above the shaft hole 71 and like the document table cover 5 indicated by a dotted line in FIG. Since the platen cover 5 can be opened while being positioned in front of the apparatus (+ Y side), interference between the platen cover 5 and the supply port cover 3 can be avoided even when the supply port cover 3 is closed.

Further, a configuration as shown in FIG. 20 can be adopted. In FIG. 20, a torsion spring 73 is provided on the first rotating shaft 13 of the supply port cover 3, and the supply port cover 3 is pressed in the opening direction.
A hook 74 is provided on the distal end 3b side of the supply port cover 3, and engages with the engaging portion 75 of the document table cover 5 when the supply port cover 3 is closed as shown in FIG. . As a result, the supply port cover 3 pressed in the opening direction is kept closed.

  When the platen cover 5 is opened, the engaging portion 75 also rotates clockwise in plan view, so that the hook 74 is disengaged from the engaging portion 75. At the same time when the hook 74 is disengaged from the engaging portion 75, the supply port cover 3 is automatically opened by the pressing force of the torsion spring 73, and is completely opened as shown in FIGS. Since the supply port cover 3 is completely opened only by slightly rotating the document table cover 5, the possibility that the open document table cover 5 interferes with the closed supply port cover 3 can be avoided.

  Further, in the printer 1, the first rotation shaft 13 which is the rotation axis of the supply port cover 3 and the second rotation shaft 14 which is the rotation axis of the image reading mechanism 4 are both connected to the housing 2. When the image reading mechanism 4 is opened from the third state to the fourth state, interference occurs between the image reading mechanism 4 and the supply port cover 3. The image reading mechanism 4 and the supply port cover 3 are integrally rotated when the image reading mechanism 4 is opened, for example, by attaching the rotation shaft 13 to the connecting portion 24 of the image reading mechanism 4. Can be. That is, since the relative position between the image reading mechanism 4 and the supply port cover 3 does not change when the image reading mechanism 4 is opened and closed, there is a problem of interference between the image reading mechanism 4 and the supply port cover 3 when the image reading mechanism 4 is opened and closed. Can be avoided.
