Japanese Patent Application Publication No. 2016-133708

However, in the above-mentioned conventional lock mechanism, because the guide surface is provided at the tip of the engaged member, the stroke amount (that is, the amount of stroke as the guide surface) is sufficient to guide the rotation of the cover from a relatively early stage. length) required for the inclined surface. Therefore, the engaged member provided with this inclined surface must be designed to be large. When the engaged member is placed close to the paper feed path in order to downsize the main body of the apparatus, if the engaged member is large as described above, the engaged member may be disposed in the ejection head provided in the paper feed path. There is a risk of interference. Therefore, it has been difficult to downsize the device body.

In the following description, an inkjet printer will be used as an example of the image recording apparatus, but the image recording apparatus is not limited to this, and may be other printers such as a laser printer or a thermal printer.

As shown in FIG. 1, an image recording device 10 to which a conveyance device 1 of the present embodiment is applied includes a housing 2 in the shape of, for example, a rectangular parallelepiped. Some of the components of the transport device 1 and the printing unit are provided within the housing 2, and other parts are provided to be exposed to the outside. Further, a manual feed tray 60 is provided, which is positioned above the cover 16 when the cover 16 is in the closed position P1, which will be described in detail later. The manual feed tray 60 is configured to be rotatable between a paper feeding position, which is an open position, and a closed position, about a rotation axis (not shown) extending in the main scanning direction Ds in the main body of the image recording device 10. There is. Note that a scanner unit may be provided on the housing 2 described above.

As shown in FIG. 2, the conveyance device 1 of the present embodiment includes a storage section (sheet feed tray) 11 that stores a sheet K, which is an example of a recording medium, a sheet feed roller 12, a conveyance roller 13, and a discharge roller 13. The roller 14, the discharge tray 15, the conveyance path H formed from the storage section 11 to the discharge tray 15 and curved backward and upward from the storage section 11, and the cover main body 25, which is formed in a roughly plate shape, for example. A cover 16 is provided. Note that the cover 16 may also be referred to as a back cover or a chute cover.

The conveyance roller 13 is arranged downstream of the cover 16 in the conveyance direction. The accommodating portion 11 is arranged in the lower part of the housing 2 . The sheet K stored in the storage section 11 is conveyed by the paper feed roller 12 toward the conveyance roller 13 via the inner surface of the cover 16 . Further, the sheet K is conveyed by a conveyance roller 13 toward a platen 20, which will be described later, and after being subjected to printing processing, is conveyed toward a discharge roller 14. Furthermore, the sheet K is conveyed toward the discharge tray 15 by the discharge roller 14.

A platen 20 is provided below the portion of the above-described transport path H between the transport roller 13 and the discharge roller 14, and an ejection head 22 that ejects ink from nozzles is attached above the platen 20. A carriage 21 is provided. The carriage 21 is movably supported by a guide frame 21a extending in the main scanning direction (horizontal direction) Ds.

In such a configuration, the sheet K fed from the storage section 11 is conveyed by the sheet feeding roller 12 toward the conveying roller 13 via the inner surface of the cover 16 . Thereafter, the sheet K is transported below the ejection head 22 by the transport roller 13. After an image is printed on the sheet K by the ejection head 22, the printed sheet K is ejected onto the ejection tray 15 by the ejection roller 14. In this way, the sheet K is conveyed along the conveyance path H formed from the storage section 11 to the discharge tray 15. Note that in addition to the above-described transport roller 13, one or more other transport rollers may be provided on the transport path H.

The cover 16 is provided on the back side (rear side) of the housing 2. The cover 16 has a pair of rotation shafts 16a located at the base end of the cover body 25. The cover 16 has a closed position P1 that partitions the transport path H (that is, a position where the cover 16 is in a closed state) and an open position that is behind the closed position P1 and opens the transport path H (that is, a position where the cover 16 is fully open). It is possible to displace (rotatable in this embodiment) between the position P2 and the state P2. In addition, in FIG. 2, the cover 16 in the open position P2 is illustrated by a two-dot chain line.

The configuration for rotating the cover 16 in the image recording apparatus 10 of this embodiment will be described below. Of the configurations for rotating the cover 16, the configuration on the cover 16 side will be explained first, and then the configuration on the transport device 1 side will be explained.

As shown in FIGS. 3 and 4, the cover 16 has a generally plate-shaped cover body 25 as described above. This cover body 25 extends along the main scanning direction Ds. The lower part of the cover main body 25 has a shorter length in the main scanning direction Ds than the remaining part thereof, and connecting parts 16b are provided at both ends of the lower part. Each connecting portion 16b includes a portion that extends vertically when the cover 16 is in the closed position P1, and a portion that extends diagonally downward and forward. Each rotation shaft 16a is provided at a corresponding connection portion 16b.

Further, a guide flap 28 is provided at the top of the cover 16. The guide flap 28, like the cover 16, is a member that partitions a part of the conveyance path H. The guide flap 28 has a curved surface portion formed in a curved shape on the side of the conveyance roller 13 . After being guided by the cover body 25, the sheet K is conveyed toward the conveyance roller 13 by sliding on the curved surface of the guide flap 28.

Further, the cover 16 is provided with a handle 27 that is operated by the user. The handle 27 is formed, for example, in a rectangular shape when viewed from the front, and is also formed in a flat plate shape except for its upper part, and is accommodated in a recess 25a formed in the upper part of the rear (outside part) of the cover main body 25. At the top of the handle 27, an operating section 27a is provided on which a user's finger is placed or held by the user's finger. The handle 27 is normally biased forward. The handle 27 is configured to rotate in conjunction with the rotation of a lever member 40, which will be described in detail later.

Here, as shown in FIG. 4, the cover 16 is provided with a defining portion 70 that comes into contact with the lever member 40 and defines the amount of deflection of the lever member 40 in the main scanning direction Ds. Specifically, each lever member 40 is provided with a defined portion 40a that is, for example, L-shaped when viewed from the front (viewed from the front) on the inner surface of the lever member 40 in the main scanning direction Ds. . The defining portion 70 has one side wall and the other side wall that are spaced apart from each other in the main scanning direction Ds, and the upper and lower portions of the L-shaped defined portion 40a are located in the area between the one side wall and the other side wall. It has been inserted. With such a configuration, the movement of each defined portion 40a in the main scanning direction Ds is regulated by each regulating portion 70, so that the amount of deflection of the lever member 40 in the main scanning direction Ds can be defined. Thereby, it is possible to ensure the flexibility of the displacement of the lever member 40 in the main scanning direction Ds, and to avoid unnecessarily bending the lever member 40 from occurring.

As shown in FIGS. 5A and 5B, a pair of lever members 40 are provided on the cover body 25 of the cover 16. As shown in FIGS. Each of the pair of lever members 40 is arranged at the upper part of the front part of the cover main body 25 at a distance from each other in the main scanning direction Ds. The handle 27 is provided with a link member 43 having a protrusion 43a held in the front portion of the handle 27, and this link member 43 is connected to a lever rotation shaft 44 extending in the main scanning direction Ds. There is. A rear end portion of the lever member 40 is connected to each of both ends of the lever rotation shaft 44 . Here, in a normal state, each lever member 40 is biased upward by a biasing member 47 (FIG. 8), which is a coil spring, for example. Therefore, the handle 27 receives force from the lever member 40 which is urged upward, and is urged forward via the lever rotation shaft 44 and the link member 43 as described above.

In the above configuration, the lever member 40 is provided at the rear portion of the cover body 25 so that its base end is rotatable about the rotation center CP. A rotation center CP of the lever member 40 is positioned below an engagement member 50, which will be described later. Further, the lever member 40 has, for example, a claw-shaped engaged portion 41 at a distal end located in front of its base end, and a guided portion 42 at a portion rearward of the distal end. The guided portion 42 is provided at the rear of the engaged portion 41 . The engaged portion 41 is engaged with each engaging member 50 when the cover 16 is in the closed position P1. In this case, the engagement between the engaging member 50 and the engaged portion 41 restricts the rotation of the cover 16 unless the handle 27 is operated by the user. The shape of each guided portion 42 is, for example, a protrusion. Further, each guided portion 42 projects outward from the lever member 40 in the main scanning direction Ds. Furthermore, each guided portion 42 is positioned below the rotation center CP of the lever member 40.

Further, an inner member 45 extending in the main scanning direction Ds is attached to the front part (inner part) of the cover main body 25. A roller support section 45a that rotatably supports a plurality of rollers 46 arranged in parallel in the main scanning direction Ds is provided at the upper part of the inner member 45.

The cover 16 can be rotated from the closed position P1 to the open position P2 as follows. As shown in FIGS. 6(a) and 6(b), when the handle 27 is rotated backward by the user (rotated clockwise in the plan view of FIG. 6(b)), the link member 43 is displaced to rotate the lever rotation shaft 44 counterclockwise in the plan view of FIG. 6(b). Accordingly, the lever member 40 rotates counterclockwise in the plan view of FIG. 6(b). This releases the engagement between the engaging member 50 and the engaged portion 41, which will be described later, so that the cover 16 can rotate from the closed position P1 to the open position P2. In this manner, the rotation direction of the handle 27 when the cover 16 is rotated from the closed position P1 to the open position P2 is the same direction as the rotation direction of the cover 16. Note that illustration of the inner member 45 and the roller support portion 45a is omitted in FIGS. 5(a), (b) and FIGS. 6(a), (b).

Here, as shown in FIG. 7, positioning of the cover body 25 in the main scanning direction Ds is performed at the center of the roller support portion 45a of the inner member 45 attached to the front part of the cover body 25 in the main scanning direction Ds. A positioning section 45b is provided. This positioning portion 45b is, for example, a recess formed in the roller support portion 45a.

On the other hand, as shown in FIG. 8, path forming members 30 and 32 are provided in front of the inner member 45 to define the transport path H together with the cover 16. The path forming member 30 is arranged between two path forming members 32 arranged along the main scanning direction Ds. The path forming members 30 and 32 are inclined downward to the right from the rear to the front in order to form the conveyance path H as described above. Note that the path forming members 30 and 32 may be formed integrally, rather than as separate members.

At the center of the upper part of the path forming member 30, a positioned portion 30a having a shape that projects upward, for example, is provided. The positioned portion 30a engages with the positioning portion 45b by fitting into the positioning portion 45b. In such a configuration, the positioning portion 45b engages with the positioned portion 30a while the cover 16 is rotating from the open position P2 toward the closed position P1.

The path forming member 30 has a plurality of protrusions 31 that protrude on its slope and are arranged in parallel in the conveying direction. In such a configuration, when a plurality of sheets K are overlapped and conveyed to the path forming member 30, the lower sheet K is caught by the protrusion 31 and separated from the upper sheet K. This can prevent a plurality of sheets K from being conveyed to the downstream side of the path forming member 30 in an overlapping state.

Next, the configuration on the transport device 1 side of the configuration for rotating the cover 16 will be described.

As shown in FIG. 9, within the housing 2, fixed chutes 51 are provided on both sides of the main scanning direction Ds. The fixed chute 51 is, for example, a member extending in the vertical direction. The fixed chute 51 is, for example, a plate-shaped member. Further, as shown in FIG. 11, when the cover 16 is in the closed position P1, the fixed chute 51 is provided so that a portion thereof is located at a position lower than the uppermost end of the cover 16.

Each fixed chute 51 is provided with an engaging member 50 that is engaged with the guided portion 42 of the lever member 40 when the cover 16 is rotating and when the cover 16 is in the closed position P1. Each engaging member 50 has a shape that projects inward in the main scanning direction Ds. Furthermore, each engaging member 50 has a tapered downstream guide surface 50a that comes into contact with the engaged portion 41 of the lever member 40 and presses the lever member 40 inward in the main scanning direction. One downstream guide surface 50a is a tapered surface that is inclined so that the distance from the other downstream guide surface 50a that forms a pair gradually narrows from the rear to the front.

Further, as shown in the figure, on each side wall 53 on both sides in the main scanning direction Ds of the opening at the rear of the housing 2, that is, the opening that is closed by the cover 16 when the cover 16 is in the closed position P1, Guide members 52 that engage with the guided portions 42 of the lever members 40 are provided, respectively .

Each guide member 52 has a tapered upstream guide surface 52a that comes into contact with the guided portion 42 of the lever member 40 and presses the lever member 40 inward in the main scanning direction Ds. One upstream guide surface 52a is a tapered surface that is inclined so that the distance from the other upstream guide surface 52a that forms a pair gradually narrows from the rear to the front.

Moreover, each guide member 52 has a push-down surface 52b and a horizontal transition surface 52c that continues in front of the push-down surface 52b. The push-down surface 52b is a surface that slopes downward from the rear toward the front, and the horizontal transition surface 52c is a substantially horizontal surface.

In the configuration in which the cover 16 is rotated as described above (the configuration on the cover 16 side and the configuration on the transport device 1 side), when the handle 27 or the cover main body 25 is pushed from the back to the front by the user, the cover 16 opens. Rotates from position P2 toward closed position P1. When the cover 16 is rotated, the guided portion 42 of the lever member 40 engages with the push-down surface 52b, and then engages with the horizontal transition surface 52c as shown in FIG. 10. In this case, each guided portion 42 engages with the push-down surface 52b while the cover 16 is rotating, so that the lever member 40 is pushed down against the upward biasing force. Then, when the cover 16 continues to be rotated, each guided portion 42 engages with the horizontal transition surface 52c, so that the lever member 40 is maintained in a depressed state, that is, the lever member 40 is pushed upward by the biasing force. Move forward while being restricted from moving forward.

Then, when the cover 16 is further rotated, the guided portion 42 is disengaged from the horizontal transition surface 52c. At this time, the engaged portion 41 of the lever member 40 moves to a position where it has already passed below the engaging member 50. As a result, when the guided portion 42 is disengaged from the horizontal transition surface 52c as described above, a biasing force is applied to the lever member 40, so that the engaged portion 41 moves upward. Rotate. As a result, as shown in FIGS. 11 and 12, when the cover 16 is located at the closed position P1, the engaged portion 41 engages with the engagement member 50 without being caught. In order to prevent such a catch, in this embodiment, the position of the engaging member 50 with respect to the guide member 52 (the relative position of the engaging member 50 and the guide member 52) is set so that the horizontal transition surface 52c of the guided portion 42 The engaged portion 41 is set at a position where the engaged portion 41 has already passed below the engagement member 50 when the engagement with the engagement member 50 is released.

As explained above, according to the conveying device 1 of the present embodiment, the guided portion 42 that engages with the guide member 52 is provided in the rear portion of the lever member 40, so that the lever The tip end portion of the lever member 40 can be made more compact than the conventional configuration in which a guided portion is provided at the tip end portion of the lever member 40. Thereby, it is possible to reduce the possibility of interference with ejection heads and the like provided in the paper feeding path in the image recording apparatus 10. Thereby, there is no need to increase the size of the device main body in order to avoid the above-mentioned interference, and the device can be made smaller than before.

Further , in this embodiment, the guide member 52 is arranged such that the guided portion 42 of the lever member 40 overlaps the guide member 52 in the main scanning direction Ds. Thereby, when the cover 16 rotates, the guided portion 42 can be guided by the guide member 52.

Further, in this embodiment, the guide member 52 has a tapered upstream guide surface 52a that comes into contact with the guided portion 42 of the lever member 40 and presses the lever member 40 inward in the main scanning direction Ds. Thereby, the cover body 25 can be moved widthwise in the main scanning direction Ds via the lever member 40, so the cover 16 can be closed with high precision.

Furthermore, in this embodiment, the engaging member 50 has a tapered downstream guide surface 50a that comes into contact with the engaged portion 41 of the lever member 40 and presses the lever member 40 inward in the main scanning direction Ds. . As a result, the cover body 25 can be moved widthwise in the main scanning direction Ds via the lever member 40, so that the cover 16 can be positioned at the closed position P1 with positional displacement in the main scanning direction Ds being suppressed or prevented. I can do it.

Further, in this embodiment, when the cover 16 rotates from the open position P2 toward the closed position P1, when the guided portion 42 of the lever member 40 and the guide member 52 are disengaged, the lever member 40 is released, and the engaged portion 41 of the lever member 40 engages with the engagement member 50. With such a configuration, it is possible to avoid an event in which the engaged portion 41 is caught on the engaging member 50 before it is engaged with the engaging member 50.

Further, in this embodiment, the guided portion 42 protrudes outward from the lever member 40 in the main scanning direction Ds. In this case, if the guided portion 42 is provided inside the lever member 40 in the main scanning direction Ds, it will be difficult to arrange the lever member 40 at a position close to the paper feed path, but this aspect can avoid such a problem. There is no.

Furthermore, in this embodiment, the guided portion 42 of the lever member 40 is positioned below the rotation center CP of the lever member 40, so if the guided portion 42 is located above the rotation center CP, Compared to this, the operational load required by the user when closing the cover 16 can be reduced.

Furthermore, in this embodiment, since the rotation center CP of the lever member 40 is positioned below the engagement member 50, the user The operational load when closing the cover 16 can be reduced.

Further, in this embodiment, while the cover 16 is rotating with the guided portion 42 of the lever member 40 engaged with the guide member 52, the positioning portion 45b engages with the positioned portion 30a. As a result, the positional deviation of the cover 16 in the main scanning direction Ds is corrected immediately before the cover 16 is positioned at the closed position P1, and the cover 16 is moved to the closed position P1 with the positional deviation in the main scanning direction Ds suppressed or prevented. It can be positioned in

Further, in this embodiment, the cover 16 is provided with a defining portion 70 that comes into contact with the lever member 40 and defines the amount of deflection of the lever member 40 in the main scanning direction Ds. With such a configuration, the movement of each defined portion 40a in the main scanning direction Ds is regulated by each regulating portion 70, so that the amount of deflection of the lever member 40 in the main scanning direction Ds can be defined. Thereby, it is possible to ensure the flexibility of the displacement of the lever member 40 in the main scanning direction Ds, and to avoid unnecessarily bending the lever member 40 from occurring. Thereby, damage to the lever member 40 can be prevented.

Furthermore, in this embodiment, the rotation direction of the handle 27 when the cover 16 is rotated from the closed position P1 to the open position P2 is the same direction as the rotation direction of the cover. Thereby, the operability when the user opens the cover 16 can be improved.
