Japanese Unexamined Patent Publication No. 2015-12409

As described above, in the conventional image recording apparatus, a sheet accommodating portion and a recording portion are provided in order from the bottom. Therefore, the vertical size of the multifunction device becomes large.

Further, in the conventional image recording device, since the recording unit is provided above the accommodating unit, in order to move the sheet in and out of the accommodating unit, the accommodating unit is moved and pulled out from the housing of the image recording device. Action was needed. Therefore, since it is necessary to provide the image recording device with a mechanism for moving the accommodating portion, the number of parts is increased by the amount of the mechanism.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an image recording apparatus capable of suppressing an increase in the number of parts and suppressing an increase in size.

(1) The image recording device according to the present invention is located inside the housing and the housing, and is formed inside the housing and the housing for accommodating the sheet. It extends to the discharge port formed on the outer surface of the housing without being inverted, and is located at a position offset in the horizontal direction with respect to the housing portion inside the housing and the transport path through which the sheet passes. A recording unit for recording an image on a sheet located in a transport path, a first opening formed above the accommodating portion and allowing the accommodating space of the sheet in the accommodating portion to be exposed to the outside of the housing, and the above. It includes a first position for exposing the first opening to the outside of the housing and a first opening / closing wall supported by the housing so as to be movable to a second position for closing the first opening.

Since the accommodating unit and the recording unit are provided at positions offset in the horizontal direction from each other, the height of the image recording device can be suppressed as compared with the configuration in which the accommodating unit and the recording unit are located above the accommodating unit.

By moving the first opening / closing wall to the first position, the sheet accommodated in the accommodating portion can be taken in and out through the first opening. Therefore, since it is not necessary to provide the image recording device with a mechanism for moving the accommodating portion, it is possible to suppress an increase in the number of parts of the image recording device.

According to the present invention, it is possible to suppress an increase in size while suppressing an increase in the number of parts.

Hereinafter, embodiments of the present invention will be described. It goes without saying that the embodiments described below are merely examples of the present invention, and the embodiments of the present invention can be appropriately changed without changing the gist of the present invention. Further, in the following description, the vertical direction 7 is defined with reference to the state in which the multifunction device 10 is usably installed (the state shown in FIG. Is defined, and 9 in the left-right direction (an example in the width direction) is defined when the multifunction device 10 is viewed from the front. The vertical direction 7, the front-rear direction 8, and the left-right direction 9 are orthogonal to each other. In the present embodiment, the vertical direction 7 is the vertical direction, and the front-rear direction 8 and the horizontal direction 9 are the horizontal directions.

The multifunction device 10 (an example of an image recording device) has a function of recording an image on paper 15 (an example of a sheet, see FIG. 2) and a function of reading an image on paper 17 (see FIG. 4). .. As shown in FIGS. 1 and 2, the multifunction device 10 includes a housing 14. The housing 14 has a substantially rectangular parallelepiped box shape. The lengths of the housing 14 in the front-rear direction 8 and the left-right direction 9 are longer than the length of the housing 14 in the vertical direction 7. The length of the housing 14 in the front-rear direction 8 is shorter than the length of the housing 14 in the left-right direction 9. The long-short relationship in each direction of the housing 14 is not limited to the above relationship. For example, the length of the housing 14 in the left-right direction 9 may be shorter than the length of the housing 14 in the front-rear direction 8.

The outer surface of the housing 14 includes a front surface 71, a rear surface 72, an upper surface 73, a lower surface 74, a right surface 75, and a left surface 76. The front surface 71, the rear surface 72, the right surface 75, and the left surface 76 are examples of side surfaces.

A discharge port 21 is formed on the front surface 71. The paper 15 on which the image is recorded or the paper 17 on which the image is read in the internal space 16 of the housing 14 is discharged to the outside of the housing 14 through the discharge port 21.

As shown in FIG. 1, a power switch 18 for starting / stopping the multifunction device 10 and various LEDs 19 are provided on the front surface 71.

The upper surface 73 of the housing 14 is composed of an upper surface of the upper wall 81 of the housing 14 and an upper surface of the opening / closing wall 82 (an example of the first opening / closing wall) of the housing 14. The upper wall 81 is a wall constituting the front upper portion of the housing 14. The opening / closing wall 82 is a wall forming the rear upper portion of the housing 14. In the present embodiment, the opening / closing wall 82 is provided from the right end to the left end of the housing 14, but the opening / closing wall 82 does not have to extend from the right end to the left end of the housing 14.

As shown in FIG. 2, the opening / closing wall 82 is rotatably supported by the upper wall 81. The opening / closing wall 82 has a covering position (an example of a second position) shown in FIGS. 1 and 2 and an exposed position (an example of the second position) shown in FIG. 3 centered on a shaft 83 provided at the rear end portion extending in the left-right direction 9. It can be rotated to (an example of the first position). As shown in FIG. 2, when the opening / closing wall 82 is in the covering position, the accommodating portion 31, which will be described later, is covered with the opening / closing wall 82 from above. As shown in FIG. 3, when the opening / closing wall 82 is in the exposed position, the accommodating portion 31 is exposed from above the housing 14 to the outside.

As shown in FIGS. 1 and 2, an opening 84 is formed in the upper surface 73 of the housing 14 (the upper surface of the opening / closing wall 82 in the present embodiment). The opening 84 may be formed on the upper surface 73 of the upper wall 81, not on the upper surface of the opening / closing wall 82. The opening 84 communicates with the transport path 39 described later. The paper 17 is inserted into the transport path 39 through the opening 84 (see FIG. 4). The opening 84 is formed long in the left-right direction 9 in accordance with the paper 17 so that the paper 17 can be inserted.

The cover 85 is rotatably supported by the opening / closing wall 82. The cover 85 can be rotated to a closed position shown in FIG. 2 and an open position shown in FIG. 4 around a shaft 86 provided at the rear end portion extending in the left-right direction 9. As shown in FIG. 2, when the cover 85 is in the closed position, the opening 84 is closed. As shown in FIG. 4, when the cover 85 is in the open position, the opening 84 is open.

When the cover 85 is in the closed position, the upward facing surface 851 of the outer surface of the cover 85 is flush with the upper surface 73 of the opening / closing wall 82. When the cover 85 is in the closed position, the surface 851 does not have to be flush with the upper surface 73 of the opening / closing wall 82, but the surface 851 is located below the upper surface 73 (that is, above the upper surface 73). It is preferable that it does not protrude).

As shown in FIG. 4, when the cover 85 is in the open position, the front-facing surface 852 of the outer surface of the cover 85 extends forward (that is, toward the discharge port 21) as it goes downward. There is. That is, the surface 852 of the cover 85 in the open position extends diagonally forward and downward from the upper end thereof. The surface 852 of the cover 85 in the open position can come into contact with the paper 17 inserted into the opening 84.

The cover 85 may extend from the upper end thereof to a position other than diagonally forward and downward. Further, the multifunction device 10 does not have to include the cover 85.

As shown in FIG. 2, the rear surface 72 of the housing 14 is provided with an opening / closing wall 87 (an example of a second opening / closing wall). The opening / closing wall 87 is rotatably supported by another portion of the housing 14. The opening / closing wall 87 has an upright position (an example of a fourth position) shown in FIG. 2 and a lodging position (third position) shown in FIG. 5 centered on a shaft 88 provided at the lower end thereof and extending in the left-right direction 9. It is rotatable to one example).

As shown in FIG. 2, when the opening / closing wall 87 is in the upright position, the accommodating portion 31 is covered with the opening / closing wall 87 from the rear. As shown in FIG. 5, when the opening / closing wall 87 is in the inverted position, the accommodating portion 31 is exposed from the rear of the housing 14 to the outside.

The multifunction device 10 does not have to include the opening / closing wall 87. That is, the rear surface 72 of the housing 14 does not have to be openable and closable. In this case, it goes without saying that the opening 42 described later is not formed on the rear surface 72.

The housing 14 has an internal space 16. The internal space 16 is partitioned by the inner surface of the housing 14. A housing unit 31, a feeding unit 33, a transport roller pair 34, a discharge roller pair 35, a recording unit 36, a platen 27, and a reading unit 37 are arranged in the internal space 16 of the housing 14. The transport paths 38 and 39 are formed in the internal space 16 of the housing 14.

The accommodating portion 31 has a box shape that is open upward. The length of the accommodating portion 31 in the front-rear direction 8 and the length in the left-right direction 9 is longer than the length of the accommodating portion 31 in the vertical direction 7. The length of the accommodating portion 31 in the front-rear direction 8 is shorter than the length of the accommodating portion 31 in the left-right direction 9. The long-short relationship in each direction of the accommodating portion 31 is not limited to the above-mentioned relationship. For example, the length of the accommodating portion 31 in the left-right direction 9 may be shorter than the length of the accommodating portion 31 in the front-rear direction 8.

The accommodating section 31 has an accommodating space 89 for the paper 15. The accommodating portion 31 is fixed to the housing 14. The accommodation space 89 is partitioned by a bottom surface 77, a front surface of the opening / closing wall 87, a right inner surface 78 of the housing 14, a left inner surface of the housing 14 (a surface facing the right inner surface 78 to the left and right, not shown), and an inclined wall 32. ing. The accommodating portion 31 can accommodate the paper 15 by stacking the paper 15 on the inside thereof.

As shown in FIG. 3, when the opening / closing wall 82 is in the exposed position, the accommodation space 89 is exposed to the outside of the housing 14 through the opening 40 (an example of the first opening). As a result, the paper 15 can be taken in and out of the accommodating portion 31 from above the accommodating portion 31 through the opening 40. The opening 40 is a portion of the accommodating portion 31 that is open upward and in which no other member (feeding portion 33 in the present embodiment) is arranged. Specifically, in FIG. 2, of the portion of the accommodating portion 31 opened upward, the portion behind the front and rear positions P1 indicated by the broken line.

As shown in FIG. 2, when the opening / closing wall 82 is in the covering position, the accommodation space 89 and the opening 40 are covered with the opening / closing wall 82 from above and are closed to the outside of the housing 14. That is, the opening / closing wall 82 can open / close the opening 40.

As shown in FIG. 5, when the opening / closing wall 87 is in the inverted position, the accommodation space 89 is exposed to the outside of the housing 14 through the opening 42 (an example of the second opening) formed in the rear surface 72. As a result, the accommodating portion 31 can support only the front portion of the paper 15 which is longer in the front-rear direction than the bottom surface 77 by the bottom surface 77, and can position the rear portion of the paper 15 outside the housing 14. As a result, the paper 15 longer in the front-rear direction than the bottom surface 77 can be fed from the accommodating portion 31 to the transport path 38, and an image can be recorded on the paper 15.

In the present embodiment, when the opening / closing wall 87 is in the upright position, the rear surface of the opening / closing wall 87 corresponds to the rear surface 72 of the housing 14. When the opening / closing wall 87 is in the inverted position, the surface that divides the opening 42 when the housing 14 is viewed from the rear corresponds to the rear surface 72 of the housing 14.

As shown in FIG. 2, when the opening / closing wall 87 is in the upright position, the accommodation space 89 and the opening 42 are covered with the opening / closing wall 87 from the rear and are closed to the outside of the housing 14.

As shown in FIG. 6, when the opening / closing wall 82 is in the exposed position and the opening / closing wall 87 is in the inverted position, the opening 40 is continuous with the opening 42. The opening 40 does not have to be continuous with the opening 42.

As shown in FIG. 2, the inclined wall 32 is located at the front end of the accommodating portion 31. In other words, the inclined wall 32 is located at the boundary between the accommodating portion 31 and the transport path 38. The inclined wall 32 projects upward from the bottom surface 77. The inclined wall 32 extends forward as it goes upward. That is, the inclined wall 32 is inclined with respect to the vertical direction 7.

The inclined wall 32 is provided with a separating portion. In the present embodiment, the separating portion is a separating piece 91 protruding from the central portion in the left-right direction 9 on the rear surface 90 of the inclined wall 32. A plurality of separation pieces 91 are provided at intervals above and below. The separation unit is not limited to the above-described configuration. For example, instead of the plurality of separating pieces 91, a member (for example, cork) having a friction coefficient higher than that of the rear surface 90 may be arranged.

The feeding unit 33 is located in a predetermined space 41 above the bottom surface 77. The predetermined space 41 is a space that is located in front of the opening 40 and is continuous with the opening 40 when the multifunction device 10 is viewed from above. That is, the predetermined space 41 is located between the opening 40 and the discharge port 21 in the front-rear direction 8. The predetermined space 41 extends in front of the feeding unit 33 (downstream in the feeding direction in which the paper 15 is fed). That is, the entire feeding unit 33 is located in the predetermined space 41. As shown in FIG. 3, when the opening / closing wall 82 is in the exposed position, the predetermined space 41 is exposed to the outside of the housing 14 in addition to the opening 40. At this time, since the space in front of the feeding unit 33 is exposed, the user can access the space in front of the feeding unit 33 in the predetermined space 41 from above.

The rear portion of the reading unit 37 is also located in the predetermined space 41.

When the opening / closing wall 82 is in the exposed position, only a part of the feeding unit 33 may be exposed to the outside of the housing 14, not the whole, as in the reading unit 37. For example, when the opening / closing wall 82 is in the exposed position, the surface of the feeding section 33 facing the rear of the feeding roller 25 is exposed to the outside of the housing 14, while the feeding roller 25 of the feeding section 33 is exposed. The front-facing surface does not have to be exposed to the outside of the housing 14. That is, the front-facing surface of the feeding roller 25 may be covered by the housing 14 regardless of the position of the opening / closing wall 82. Further, for example, regardless of the position of the opening / closing wall 82, the entire feeding unit 33 may be covered with the housing 14.

Further, the entire reading unit 37 may be located in the predetermined space 41. Further, members other than the feeding unit 33 and the reading unit 37 may be located in the predetermined space 41.

As shown in FIG. 2, the feeding unit 33 includes a feeding roller 25, a feeding arm 26, and a shaft 28. The feeding roller 25 is rotatably supported by the tip of the feeding arm 26. The feeding arm 26 rotates about a shaft 28 provided at the base end portion. As a result, the feeding roller 25 can come into contact with and separate from the bottom surface 77 or the paper 15 supported by the bottom surface 77.

The feeding roller 25 rotates by transmitting the driving force of the feeding motor (not shown). As a result, the plurality of sheets 15 supported by the bottom surface 77 are fed forward. The plurality of sheets 15 fed forward come into contact with the separation piece 91. As a result, the topmost paper 15 of the plurality of papers 15 is separated from the other papers 15 and fed to the transport path 38 along the rear surface 90 of the inclined wall 32.

The transport path 38 is a space partitioned by a guide member (not shown), a transport roller pair 34, a discharge roller pair 35, a recording unit 36, and a platen 27 arranged in the internal space 16 of the housing 14. The transport path 38 is a path through which the paper 15 fed by the feeding section 33 passes. The transport path 38 extends forward from the front end of the accommodating portion 31 (in other words, the upper end of the inclined wall 32) without being inverted, and reaches the discharge port 21.

The transport path 38 may extend without being inverted. That is, the transport path 38 is not limited to the path extending straight forward as shown in FIG. For example, the transport path 38 may extend upward as it goes forward. In this case, the discharge port 21 may be provided on the upper surface 73 instead of the front surface 71. That is, the position where the discharge port 21 is provided is not limited to the front surface 71. Further, for example, the transport path 38 may have a portion that curves upward or downward.

The transport path 39 is a space partitioned by a guide member (not shown) arranged in the internal space 16 of the housing 14 and a reading unit 37. The transport path 39 is a path through which the paper 17 (see FIG. 4) inserted through the opening 84 passes. The transport path 39 extends forward (that is, toward the discharge port 21) from the opening 84 downward. That is, the transport path 39 extends diagonally forward and downward from the opening 84. The transport path 39 may extend from the opening 84 in a direction other than diagonally forward and downward.

One end of the transport path 39 merges with the transport path 38 at the confluence position P2. The other end of the transport path 39 communicates with the opening 84. That is, the paper 17 inserted through the opening 84 passes through the transport path 39 and then passes through the transport path 38. That is, the transport path 38 is a path through which the paper 15 fed by the feeding unit 33 passes, and also a path through which the paper 17 inserted through the opening 84 passes.

The transport roller pair 34 is arranged in the transport path 38. The transfer roller pair 34 includes a transfer roller 61 and a pinch roller 62. The pinch roller 62 is pressed against the transport roller 61 by an elastic member (not shown) such as a spring. As a result, the transfer rollers vs. 34 can hold the papers 15 and 17.

The discharge roller pair 35 is arranged in front of the transport roller pair 34 in the transport path 38 (downstream in the transport direction of the papers 15 and 17). The discharge roller pair 35 includes a discharge roller 64 and a spur 65. The spur 65 is pressed against the discharge roller 64 by an elastic member (not shown) such as a spring. As a result, the discharge roller pair 35 can hold the papers 15 and 17.

The transfer roller 61 and the discharge roller 64 are driven by transmitting the driving force of a transfer motor (not shown). The transfer roller 61 to which the driving force is transmitted conveys the papers 15 and 17 forward (in the transfer direction) while sandwiching the papers 15 and 17 with the pinch roller 62. The discharge roller 64 to which the driving force is transmitted conveys the papers 15 and 17 forward (in the conveying direction) while sandwiching the papers 15 and 17 with the spur 65.

The recording unit 36 is located in the internal space 16. The recording unit 36 is located between the transport roller pair 34 and the discharge roller pair 35 in the transport path 38. The recording unit 36 is located in front of the accommodating unit 31. In other words, the recording unit 36 is at a position offset forward (in the direction along the upper surface 73) with respect to the accommodating unit 31. The recording unit 36 is located above the accommodating unit 31 and the inclined wall 32.

In the present embodiment, the recording unit 36 records an image on the paper 15 transported along the transport path 38 by an inkjet method. The method in which the recording unit 36 records an image on the paper 15 is not limited to the inkjet method, and may be another method such as an electrophotographic method.

The platen 27 is provided below the recording unit 36 so as to face the recording unit 36. The platen 27 supports the papers 15 and 17 transported along the transport path 38.

The reading unit 37 is located in the transport path 39 of the internal space 16. The reading unit 37 is located behind the recording unit 36. The reading unit 37 is located in front of the opening 84. That is, the reading unit 37 is located on the discharge port 21 side of the opening 84 and between the opening 84 and the recording unit 36 in the front-rear direction 8. The reading unit 37 is located above the accommodating unit 31 and the inclined wall 32. In the present embodiment, the reading unit 37 is located directly above the accommodating unit 31. The reading unit 37 acquires image data by reading the image inserted through the opening 84 and recorded on the paper 17 located on the transport path 39 by the image sensor.

[Effect of Embodiment]
Since the accommodating unit 31 and the recording unit 36 are provided at positions offset from each other in the horizontal direction (in the front-rear direction in this embodiment), the multifunction device 10 has a configuration in which the recording unit 36 is located on the accommodating unit 31. The height can be suppressed.

By moving the opening / closing wall 82 to the exposed position, the paper 15 accommodated in the accommodating portion 31 can be taken in and out through the opening 40. Therefore, since it is not necessary to provide the multifunction device 10 with a mechanism for moving the accommodating portion 31, it is possible to suppress an increase in the number of parts of the multifunction device 10.

By moving the opening / closing wall 87 to the inverted position, the multifunction device 10 can be made to correspond to the image recording on the large-sized paper 15 protruding from the accommodating portion 31.

When the opening / closing wall 82 is moved to the exposed position and the paper 15 stored in the accommodating portion 31 is taken in and out through the opening 40, the opening / closing wall 87 is moved to the inverted position to form a large opening consisting of the continuous opening 40 and the opening 42. Can be formed. As a result, the paper 15 can be easily taken in and out of the accommodating portion 31.

Since the accommodating portion 31 is fixed to the housing 14 and the accommodating portion 31 does not move, no parts for the movement are required.

Since the predetermined space 41 is exposed in addition to the opening 40 when the opening / closing wall 82 is in the exposed position, the visibility of the accommodating portion 31 can be improved when the paper 15 accommodated in the accommodating portion 31 is taken in and out.

The predetermined space 41 extends to the front of the feeding unit 33. Therefore, when the opening / closing wall 82 is in the exposed position, the portion of the paper 15 that has passed through the feeding portion 33 can be visually recognized, and the user can access the portion. As a result, it is easy to take out the jammed paper 15 with a part of the paper passing through the feeding unit 33.

In the configuration including the inclined wall 32 and the separation piece 91 as in the present embodiment, the paper 15 can be separated without causing back tension (tension in the direction opposite to the transport direction of the paper 15) with respect to the paper 15. is there. Therefore, even when a part of the paper 15 on which the image is recorded by the recording unit 36 is located on the inclined wall 32, the image recording on the paper 15 is not affected by the back tension.

The length of the housing 14 in the front-rear direction 8 is shorter than the length of the housing 14 in the left-right direction 9. Therefore, it is possible to suppress an increase in the size of the multifunction device 10 in the front-rear direction 8. Further, when the multifunction device 10 is made to correspond to the image recording on the large size paper 15 protruding from the accommodating portion 31 by providing the opening / closing wall 87, it is easy to make the multifunction device 10 correspond to the larger size paper 15.

The opening / closing wall 82 extends from the right end to the left end of the housing 14. Therefore, it is easy to access the opening / closing wall 82 from both sides in the left-right direction 9 to open / close the opening / closing wall 82. Further, by improving the sense of unity between the opening / closing wall 82 and the housing 14, the aesthetic appearance of the multifunction device 10 can be enhanced.

[Modification example]
In the above embodiment, the reading unit 37 is located in the transport path 39 and is located directly above the accommodating unit 31, but the position of the reading unit 37 is not limited to such a position. For example, the reading unit 37 may be located in the transport path 38. In this case, the reading unit 37 may be located behind the recording unit 36 (between the merging position P2 and the recording unit 36) or in front of the recording unit 36 (between the recording unit 36 and the discharge port 21). It may be located. In this case, since the reading unit 37 is located in front of the accommodating unit 31, it is not located directly above the accommodating unit 31.

In the above embodiment, the opening / closing wall 82 has moved to the covering position and the exposed position by rotation, but may move to the covering position and the exposed position by other than rotation.

For example, as shown in FIG. 7, the opening / closing wall 82 may be detachable from the housing 14. In this case, the opening / closing wall 82 is the covering position when it is attached to the housing 14 as shown by the broken line in FIG. 7, and is exposed when it is removed from the housing 14 as shown by the solid line in FIG. The position.

In the configuration shown in FIG. 7, since the opening / closing wall 82 is removed from the housing 14, the paper 15 housed in the housing section 31 can be easily taken in and out.

Further, for example, as shown in FIG. 8, the opening / closing wall 82 may be supported by the housing 14 so as to be slidable back and forth. In this case, the opening / closing wall 82 is the covering position at the position shown by the broken line in FIG. 8, and the exposed position at the position shown by the solid line in FIG. 8 (the position slid rearward from the covering position). The sliding direction of the opening / closing wall 82 is not limited to the front-rear direction. For example, the opening / closing wall 82 may be slidably supported by the housing 14 in the left-right, up-down, diagonally upward, and the like.

In the configuration shown in FIG. 8, since the opening / closing wall 82 does not move upward, the height of the multifunction device 10 can be suppressed.

Further, for example, as shown in FIG. 9, the opening / closing wall 82 may be connected to another portion of the housing 14 (in FIG. 9, the side wall 93 of the housing 14) via the connecting member 92.

Two connecting members 92 are provided at each of the upper right end portion and the upper left end portion of the housing 14 at intervals of front and rear. The number of connecting members 92 is not limited to the above.

One end of the connecting member 92 is connected to the side wall 93. The other end of the connecting member 92 is connected to the opening / closing wall 82. The connecting member 92 is rotatable about a shaft 94 extending in the left-right direction 9 with respect to the side wall 93, and is rotatable about a shaft 95 extending in the left-right direction 9 with respect to the opening / closing wall 82.

The opening / closing wall 82 is a covering position at the position shown by the broken line in FIG. At this time, the connecting member 92 extends back and forth. When the connecting member 92 rotates in the direction of the arrow 96, the opening / closing wall 82 is lifted with respect to the other portion of the housing 14, and the exposed position shown by the solid line in FIG. 9 is obtained. The opening / closing wall 82 at the exposed position is at a position offset forward and upward with respect to the opening / closing wall 82 at the covering position.

In the configuration shown in FIG. 9, since the connecting member 92 is configured to rotate around an axis extending in the left-right direction, the opening / closing wall 82 at the exposed position becomes the opening / closing wall 82 at the covering position. It was in a position offset forward and upward, but it is not limited to this. For example, the connecting member 92 is configured to rotate about an axis extending in the front-rear direction, and the opening / closing wall 82 at the exposed position is offset in the left-right direction and upward with respect to the opening / closing wall 82 at the covering position. It may be in position.

In the configuration shown in FIG. 9, the opening / closing wall 82 at the exposed position is at a position offset in two directions, the horizontal direction and the upward direction, with respect to the opening / closing wall 82 at the covering position. Therefore, the opening 40 is opened while reducing the amount of offset in each of the two directions as compared with the configuration in which the opening / closing wall 82 at the exposed position is offset in only one direction (horizontal direction or upward direction) with respect to the opening / closing wall 82 at the covering position. It can be greatly exposed.

Like the opening / closing wall 82, the cover 85 may be moved to the closed position and the open position by other than rotation, and the opening / closing wall 87 may be moved to the upright position and the lying position by other than rotation.

In the above embodiment, as shown in FIG. 1, the upper surface 73 of the housing 14 is composed of the upper surface of the upper wall 81 of the housing 14 and the upper surface of the opening / closing wall 82 of the housing 14.

However, the upper surface 73 of the housing 14 may be composed of only the upper surface of the opening / closing wall 82. That is, the housing 14 does not have to include the upper wall 81. That is, the opening / closing wall 82 constitutes at least a part of the upper surface 73 of the housing 14.

A cover may be provided to cover at least a part of the member located in the predetermined space 41. For example, as shown in FIG. 10, a cover 97 that covers the feeding unit 33 and the reading unit 37 from above may be provided. The cover 97 is provided at a position capable of preventing the user from directly touching the members (feeding unit 33 and reading unit 37 in FIG. 10) located in the predetermined space 41 when the opening / closing wall 82 is in the exposed position. On the other hand, the cover 97 is not provided at a position that hinders the function of the member. For example, the cover 97 does not cover the downward-facing surface of the feeding roller 25 because the downward-facing surface needs to come into contact with the paper 15.

By providing the cover 97, it is possible to prevent the user from touching the member arranged in the predetermined space 41.

As shown in FIG. 11, the multifunction device 10 may include a tray 98 rotatably supported by the housing 14. The tray 98 is located behind the opening 84. The tray 98 can be rotated around a shaft 99 provided at the front end thereof in the left-right direction 9 to a first position shown by a broken line in FIG. 11 and a second position shown by a solid line in FIG. is there.

When the tray 98 is in the first position, the upper surface 981 of the tray 98 is flush with the upper surface 73 of the housing 14. When the tray 98 is in the second position, the upper surface 981 of the tray 98 extends rearward (that is, away from the discharge port 21 in the front-rear direction 8) from the upper surface 73 upward. When the tray 98 is in the second position, the upper surface 981 of the tray 98 can support the paper 17 inserted into the opening 84.

In FIG. 11, the shaft 83 of the opening / closing wall 82 is provided at the front end portion of the opening / closing wall 82, but the shaft 83 may be provided at the rear end portion of the opening / closing wall 82 as in FIG. Further, in FIG. 11, the tray 98 is provided in place of the opening / closing wall 82, and the tray 98 has a function of the opening / closing wall 82 (a function of exposing the accommodating portion 31 to the outside). However, the tray 98 may be provided in addition to the opening / closing wall 82. For example, the tray 98 may be rotatably supported by an opening / closing wall 82.

In the above embodiment, the accommodating portion 31 is fixed to the housing 14, but the accommodating portion 31 may not be fixed to the housing 14.

In the above embodiment, the feeding unit 33 includes a feeding arm 26 and a feeding roller 25 rotatably supported at the tip of the feeding arm 26. Then, the paper 15 housed in the storage unit 31 was fed along the inclined wall 32, and the uppermost paper 15 was separated from the other paper 15 by the separation piece 91. However, the configuration in which the paper 15 is fed is not limited to the configuration including the feeding arm 26, the feeding roller 25, the inclined wall 32, and the separating piece 91. For example, a feeding roller may be provided at the upper end of the front end of the accommodating portion 31 (the boundary between the accommodating portion 31 and the transport path 38), and the bottom surface 77 may be urged upward by a spring or the like. In this case, the top 15 of the paper 15 supported on the bottom surface 77 comes into contact with the feeding roller from below, and the top 15 is fed by the feeding roller.

In the above embodiment, as an example of the image recording device, the multifunction device 10 having the functions of a printer and a scanner has been described. However, the image recording device is not limited to the multifunction device 10. For example, the image recording device may be a printer that does not have a scanner function.
