[Solution] The device comprises a recording unit for recording on a sheet, a sheet discharge unit for discharging the recorded sheet, a discharge tray for stacking the discharged sheet, an upper housing positioned above the discharge tray, and sheet guide ribs positioned along the bottom surface of the upper housing to guide the discharged sheet, wherein the discharge tray has a recess located directly below the sheet guide ribs.

Description

Technical Field

[0001] The present invention relates to a recording apparatus.

Background Art

[0002] In a recording apparatus such as an inkjet printer, in order to save space, reduce size, and make it thinner, there is an in-body paper discharge configuration that discharges paper below an image reading unit (scanner unit). When narrowing the paper discharge space in consideration of the size of the recording apparatus, a sheet guide rib is arranged to prevent paper jams (paper jams) on the bottom surface of the scanner unit. The sheet guide rib is a member for suppressing the curling of the paper.

[0003] However, in order to suppress the curling of the paper, it is necessary to narrow the distance between the sheet guide rib and the discharge tray to a certain extent. Therefore, there is a problem that the paper discharge extraction space becomes narrow. Therefore, Patent Document 1 proposes not to extend the length of the sheet guide rib to the most downstream (front surface of the recording apparatus) in order to secure the paper discharge extraction space.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in Patent Document 1, when the curled sheet always comes along the upper surface, the curling of the paper cannot be suppressed using a short sheet guide rib. In particular, in an inkjet recording apparatus, the curling of the paper immediately after printing is very large, and jams may occur.

[0006] Therefore, an object of the present invention is to suppress the occurrence of jams and improve the paper discharge extraction property.

Means for Solving the Problems

[0007] To achieve the object of the present invention, a recording device according to one embodiment has the following configuration: a recording unit for recording on a sheet, a sheet discharge unit for discharging the recorded sheet, a discharge tray for stacking the discharged sheet, an upper housing disposed above the discharge tray, and a sheet guide rib disposed along the bottom surface of the upper housing to guide the discharged sheet, wherein the discharge tray has a recess located directly below the sheet guide rib. [Effects of the Invention]

[0008] According to the present invention, jamming can be suppressed and paper ejection can be improved. [Brief explanation of the drawing]

[0010] The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims. While the embodiments describe multiple features, not all of these features are essential to the invention, and the features may be combined in any way. Furthermore, in the attached drawings, identical or similar configurations are given the same reference numerals, and redundant descriptions are omitted.

[0011] (First Embodiment) Figure 1(a) is an overall perspective view of the recording device 1 according to the first embodiment.

[0012] (Regarding the overall configuration of recording device 1) The recording device 1 is an inkjet printer. The recording device 1 comprises a main unit 100, a cassette 2, an output tray 17, and an output tray 120 (see Figure 1(c)). The main unit 100 is defined by a housing 101. The cassette 2, output tray 17, and output tray 120 are attached to the main unit 100. A scanner unit 900 is provided above the housing 101 as an upper housing, but is not limited to this. A cover member 300 (see Figure 6(a)) may also be provided above the housing 101 as an upper housing. In this specification, "upper housing" refers to the scanner unit 900 or the cover member 300.

[0013] Here, the same definitions can be applied to other figures other than FIGS. 1(a) to 1(c). However, for ease of understanding of the structure, the X, Y, and Z directions that intersect (substantially orthogonal) to each other are shown in the figures. The X direction corresponds to the left-right direction or the width direction. The Y direction corresponds to the front-back direction or the depth direction. The Z direction corresponds to the up-down direction or the height direction. Note that the -X side is the left side, and the +X side is the right side. The -Y side is the front side, and the +Y side is the back side. The -Z side is the bottom side, and the +Z side is the top side. However, in the following description, when the distinction between one side or the other side is unnecessary, it is simply indicated as the X, Y, or Z direction. Also, both the X and Y directions may be expressed as the horizontal direction. The Z direction may be expressed as the vertical direction.

[0014] FIG. 1(b) is a diagram for explaining the internal configuration of the recording apparatus 1 according to the first embodiment. FIG. 1(c) is a diagram for explaining the discharge tray 17 and the discharge tray 120 according to the first embodiment.

[0015] The scanner unit 900 is installed in the housing 101 so as to rotate in the Y direction with the shaft portion 901 as the rotation axis. In this specification, the upper housing (scanner unit 900) is configured to rotate in the depth direction (Y direction) of the recording apparatus 1. Also, a sheet guide rib 200 is disposed along the bottom surface of the scanner unit 900 (upper housing) so as to guide the discharged sheet to the foremost side (-Y side) of the scanner unit 900 (upper housing). In this specification, the scanner unit 900 is a device for reading an image. The image is at least one of the image recorded by the recording apparatus 1 on the paper and the image previously recorded on the paper.

[0016] The front surface 101a of the main body 100 is provided with a slot 111 for slidably housing the cassette 2 shown in Figure 1(a) in the Y direction. The cassette 2 can be inserted into and removed from the slot 111. One or more sheets SH (see Figure 2) are loaded and housed in the cassette 2. The sheets SH can be any sheet-shaped recording medium made of paper. Cut sheets conforming to a predetermined standard size (for example, A4 size) are used as sheets SH. The cassette 2 may also be referred to as a sheet cassette or a storage cassette.

[0017] The output trays 17 and 120 are provided between the upper surface 101b of the main body 100 and the lower part of the scanner unit 900. Recorded sheets SH that have been ejected outside the main body 100 are placed on the output trays 17 and 120. The output trays 17 and 120 are each provided to seal the inside of the main body 100 in an openable and closable manner. When the main body 100 is closed, the output tray 17 is located on the -Y side relative to the output tray 120 (see Figure 1(c)).

[0018] The discharge tray 17 includes a plate-shaped member 17a and a shaft portion 17b (see Figure 1(b)). The plate-shaped member 17a is pivotally supported by the shaft portion 17b at the +Y end of the housing 101. The discharge tray 17 is rotatable about the X direction as the pivot axis. This allows the opening 70 at the top of the housing 101 to be in an open state (see Figure 1(b)) or a closed state (see Figure 1(a)).

[0019] Here, with the opening 70 closed (see Figure 1(a)), the plate-like member 17a forms a substantially horizontal surface on the -Y side and an inclined surface on the +Y side. The inclined surface of the plate-like member 17a is inclined such that the +Y side is lower and the -Y side is higher.

[0020] The discharge tray 120 includes a plate-shaped member 120a and a shaft portion 120b (see Figure 1(c)). The shaft portion 120b is provided at both ends (side portions) of the plate-shaped member 120a in the X direction. A guide rail 121 extends from the wall portion of the housing 101 facing the shaft portion 120b, along the inclined surface of the closed plate-shaped member 17a. The shaft portion 120b is slidably engaged with the guide rail 121.

[0021] As a result, the discharge tray 120 can slide up to the top of the inclined surface of the closed discharge tray 17. The opening 130 at the top of the housing 101 can be set to an open state (see Figure 1(c)) or a closed state (see Figure 1(a)).

[0022] The openings 70 and 130 may be integrally formed in the upper part of the housing 101. For ease of understanding, the portion opened by the rotation of the discharge tray 17 is referred to as opening 70. The portion opened by the sliding of the discharge tray 120 is referred to as opening 130.

[0023] After opening the scanner unit 900, the user can relatively easily expose the inside of the main body 100 by rotating the output tray 17 or sliding the output tray 120. This allows the user to view and access the inside of the main body 100 through the opening 70 or the opening 130.

[0024] Thus, the discharge trays 17 and 120 function as mounting sections on which recorded sheets SH discharged outside the main body 100 are placed, and also function as cover sections that can be opened and closed to seal the inside of the main body 100. Therefore, both the discharge trays 17 and 120 may be referred to as discharge tray covers. Alternatively, to distinguish between the two discharge trays, the discharge tray 17 may be referred to as a rotating cover, and the discharge tray 120 may be referred to as a sliding cover.

[0025] (Regarding the internal structure of recording device 1) Figure 2 is a cross-sectional view showing the internal structure of the recording device 1 according to the first embodiment.

[0026] The recording device 1 further comprises a recording unit 10, a drive unit 14, a platen 15, a plurality of transport units 3 to 9, a plurality of sensors 32 to 34, and a flapper 180 within the main body 100.

[0027] The recording unit 10 includes a carriage 11 and a recording head 12. In this specification, the recording unit 10 is a unit that records images onto a sheet SH. The carriage 11 is configured to mount the recording head 12 and to be reciprocally movable in the X direction. As a result, the recording head 12 is scannable in the X direction. Multiple nozzles are arranged on the surface of the recording head 12 facing the platen 15. Each nozzle ejects ink supplied from an ink tank (not shown) via an ink tube.

[0028] The drive unit 14 drives the recording unit 10. The drive unit 14 includes a travel track for moving the carriage 11 back and forth, a pulley for traveling on the travel track, and an electric motor for driving the pulley.

[0029] As a result, the drive unit 14 moves the carriage 11 back and forth to scan the recording head 12 while the sheet SH passes between the recording head 12 and the platen 15. The drive unit 14 then drives the recording head 12 to eject ink from each nozzle. This records the sheet SH.

[0030] Here, "recording" refers to forming an image by ejecting ink onto sheet SH. The concept of an image includes letters, numbers, symbols, figures, and photographs, regardless of their legibility. The ink is typically a liquid containing dyes and pigments, but it may also be a colorless, transparent reaction solution, and both can be collectively referred to as a liquid. From this perspective, recording device 1 may be referred to as a liquid ejection device. Similarly, recording head 12 may be referred to as a liquid ejection head.

[0031] In this embodiment, recording on the sheet SH is achieved by alternating between an operation that transports the sheet SH a predetermined distance and then suppresses the transport (intermittent transport) and an operation in which the recording head 12 scans and records while the transport is suppressed (recording scan). Such a recording head 12 is also referred to as a serial head. In another embodiment, the recording head 12 may be a line head capable of recording the entire width of the sheet SH at once.

[0032] Each of the transport units 3 to 9 is positioned at a corresponding location along the transport path of the sheet SH (shown by dashed arrows). The sheet SH is transported by the drive roller rotating while gripping the sheet SH together with the driven roller or driven spur. The driven roller is positioned on the side of the sheet SH before recording to be recorded. The driven spur is positioned on the side of the sheet SH after recording to which the recording has been made. Each of the driven rollers and driven spurs is positioned so as to be rotatable and in contact with the corresponding drive roller, biased against the drive roller by a biasing means (not shown).

[0033] The conveying unit 3 includes a drive roller and a driven roller that are in contact with each other. The conveying unit 3 conveys the sheet SH picked up from the cassette 2 (see arrow A1). The conveying unit 4, like the conveying unit 3, also includes a drive roller and a driven roller that are in contact with each other, and further conveys the sheet SH conveyed by the conveying unit 3 (see arrow A2).

[0034] Furthermore, the transport unit 4 can receive and transport sheets SH from the external paper feed unit 19, which is additionally attached to the lower part of the main body 100 (see arrow A3).

[0035] The transport units 5 and 6 are capable of intermittent transport and constant-speed transport. Transport unit 5 is positioned upstream of the recording unit 10 in the transport direction. Transport unit 5 includes drive rollers and driven rollers that are in contact with each other. Transport unit 5 intermittently transports the sheet SH toward the recording unit 10.

[0036] Furthermore, the transport unit 6 is positioned downstream of the recording unit 10 in the transport direction. The transport unit 6 includes drive rollers and driven spurs that are in contact with each other. The transport unit 6 intermittently transports the recorded sheet SH further downstream by the recording unit 10 (see arrow A4).

[0037] Each of the transport units 7 to 9 includes a drive roller and a driven spur that are in contact with each other. The transport units 7 to 9 are arranged along a discharge path (or discharge transport path) for discharging the recorded sheet SH transported from transport unit 6 to the outside of the main body 100. That is, the discharge path refers to the path through which the sheet SH can pass from transport unit 6 to transport unit 9, as shown by arrow A1, etc., within the transport path of the sheet SH.

[0038] This discharge path has a curved path from the lower rear to the upper rear within the main body 100 (see arrow A5). The recorded side of the sheet SH is ejected into the discharge tray 17 and discharge tray 120 inverted so that the recorded side faces downwards. This type of discharge is called "face-down paper output".

[0039] In the curved discharge path described above, transport unit 7 is located at the bottom, transport unit 8 is located at the rearmost position, and transport unit 9 is located at the top. Thus, transport units 7 through 9 can be distinguished from each other.

[0040] In the transport units 6 to 9 located downstream of the recording unit 10, the driven spur is positioned on the side of the sheet SH that has been recorded, and the drive roller is positioned on the opposite side of the sheet SH that has been recorded.

[0041] Note that transport units 3 to 9 may be referred to by other names depending on their purpose, use, and placement, in order to distinguish them from one another. For example, transport units 3 and 4 may be referred to as paper feeding units. Transport units 7 to 9 may be referred to as paper discharge units. In this specification, the sheet discharge section is a component that discharges the sheets recorded by the recording unit 10, and refers to transport units 7 to 9.

[0042] Sensors 32-34 are configured to detect the presence or absence of sheet SH. Sensors 32-34 detect, for example, the passage of the front end (downstream end) and rear end (upstream end) of sheet SH. Typically, known optical sensors are used as sensors 32-34.

[0043] The sensor 32 is positioned upstream of the recording unit 10 (in this embodiment, upstream of the transport unit 5).

[0044] The sensor 33 is positioned downstream of the recording unit 10 (in this embodiment, downstream of the transport unit 6 and near the transport unit 7).

[0045] The sensor 34 is positioned downstream of the curved discharge path (in this embodiment, near the transport unit 9). This allows the position of the sheet SH to be transported to be identified.

[0046] The case described above involves recording only one side of sheet SH, but recording device 1 can also record on the opposite side of sheet SH (so-called double-sided printing is possible). Sheet SH, with only one side recorded, is transported partway along a curved discharge path. Then, sheet SH is returned to transport unit 4 by transport units 5-9, passing through recording unit 10, and is flipped over when it returns to transport unit 4 (see arrow A6). Sheet SH is then transported back to recording unit 10, where recording is performed on the other side of sheet SH.

[0047] (Regarding the relationship between the discharge tray and the sheet guide ribs) Figure 3(a) is a diagram illustrating the paper output and stacking section according to the first embodiment. Figure 3(b) is a view of the paper output and stacking section from the front of the main body. Figure 3(c) is a cross-sectional view taken along the BB line in Figure 3(b). As described above, the output tray 17 and the output tray 120 are located at the bottom of the scanner unit 900. Sheet guide ribs 200 are located on the bottom surface of the scanner unit 900.

[0048] The sheet guide ribs 200 can suppress curling of the ejected sheets SH2. If the sheet guide ribs 200 are not installed, the curled sheets SH2 will collide with the bottom surface of the scanner unit 900, making sheet jams more likely. It is desirable that the sheet guide ribs 200 be parallel to the output trays 17 and 120 when viewed in the YZ cross-section.

[0049] Furthermore, the front portion of the output tray 17 includes an inclined surface 17c parallel to the sheet guide rib 200 and a substantially horizontal surface 17d with a small angle to the XY horizontal plane. In this specification, the output tray 17 has at least an inclined surface 17c parallel to the sheet guide rib 200 and a substantially horizontal surface 17d. This configuration of the output tray 17 results in a greater distance between the scanner unit 900 and the paper output stacking surface compared to a configuration where the inclined surface 17c extends to the very front of the output tray 17. As a result, the ease of removing the stacked paper output sheets is improved.

[0050] In addition, the front surface of the discharge tray 17 directly below the sheet guide rib 200 in the Z direction has a shape that curves from the substantially horizontal plane 17d to the surface 17e below in the Z direction. This ensures that even if the sheet guide rib 200 extends to the front surface of the discharge tray 17, a space can be secured between the sheet guide rib 200 and the discharge tray 17. As a result, the ease of removing the stacked paper is improved.

[0051] Figure 4(a) is a perspective view showing the housing of the first embodiment in an open state. Figure 4(b) is a side view showing the housing of the first embodiment in an open state. In Figures 4(a) and 4(b), the scanner unit 900 rotates in the Y direction around the shaft portion 901, and the output tray 17 rotates around the shaft portion 17b. In this specification, the scanner unit 900 (upper housing) is configured to rotate in the Y direction (depth direction of the recording device 1). The output tray 17 is configured to rotate in the same direction (Y direction) as the scanner unit 900 (upper housing). As a result, the housing 101 takes an open state (a state in which the opening 70 is visible).

[0052] At this time, the sheet guide rib 200 and the output tray 17 overlap in the X direction (see Figure 4(b)). In this specification, when the output tray 17 and the scanner unit 900 (upper housing) are rotated to a predetermined position in the Y direction (depth direction of the recording device 1), the sheet guide rib 200 and the output tray 17 overlap in the X direction (width direction of the recording device 1). In other words, the sheet guide rib 200 and the output tray 17 are aligned linearly in the Z direction (height direction of the recording device 1). This makes it possible to reduce the opening angle of the scanner unit 900 when opening the opening 70. Therefore, even if the recording device 1 is installed in a narrow installation area (a space or location with low height in the Z direction), the user can perform maintenance on the recording device 1.

[0053] Furthermore, when the scanner unit 900 is closed, the sheet guide rib 200 comes into contact with the surface 17e of the output tray 17. In this specification, after the sheet guide rib 200 comes into contact with the surface 17e (recess) of the output tray 17 at a predetermined position in the Y direction (depth direction of the recording device 1), the output tray 17 rotates in conjunction with the rotation of the scanner unit 900 (upper housing) to close. Therefore, the user can close the scanner unit 900 and the output tray 17 simultaneously with a single operation of closing the scanner unit 900. This improves user convenience.

[0054] Figure 5(a) is a diagram illustrating the positional relationship between the sheet guide rib 200 and the discharge tray 17 according to Embodiment A. Figure 5(a) is a front view of the recording device 1.

[0055] Example A shows the optimal arrangement of the sheet guide ribs 200 and the output tray 17 when the sheet SH3 has a downward convex shape and curls. For example, Example A can be applied when the recording method is an inkjet method and face-down output is used, where the printed surface is located downward in the Z direction. Sheet guide ribs 200 are placed at both ends of the sheet SH3 in the width direction. Here, in order to distinguish between the two sheet guide ribs 200, the sheet guide rib 200 on the left in Figure 5(a) is called the "sheet guide rib," and the sheet guide rib 200 on the right is called the "other sheet guide rib." In this specification, the right sheet guide rib 200 (other sheet guide rib) is placed parallel to the left sheet guide rib 200 (sheet guide rib) on the bottom surface of the scanner unit 900 (upper housing). The left sheet guide rib 200 (sheet guide rib) guides the left portion of the sheet SH3 in the width direction (X direction). On the other hand, the right-side sheet guide rib 200 (the other sheet guide rib) guides the right-side portion of the sheet SH3 in the width direction (X direction) of the sheet SH3. In this specification, the distance between the left-side sheet guide rib 200 and the right-side sheet guide rib 200 (referred to as the other sheet guide rib) in Figure 5(a) is preferably 100 mm or more. The substantially horizontal surface 17d of the discharge tray 17 is located in the center of the width of the sheet SH3. The two surfaces 17e are located directly below the sheet guide ribs 200 at both ends of the width of the sheet SH3 in the Z direction. Here, in order to distinguish between the two surfaces 17e, the left-side surface 17e in Figure 5(a) is referred to as the "recess," and the right-side surface 17e is referred to as the "other recess." In this specification, the surface 17e is referred to as the "recess" located directly below the sheet guide rib 200 that is located on the front side of the scanner unit 900 (upper housing) among the sheet guide ribs 200. Here, the substantially horizontal surface 17d relative to the "recess" may be called the "convex portion." The XZ cross-sectional shape of the sheet guide rib 200 is preferably V-shaped to match the curl shape of the sheet SH3, but is not limited to this. In this specification, the cross-sectional shape (XZ cross-sectional shape) of the sheet guide rib 200 in the width direction (X direction) of the sheet SH3 is tapered towards the tip, and is preferably V-shaped.

[0056] Figure 5(b) is a diagram illustrating the positional relationship between the sheet guide rib 200 and the discharge tray 17 according to Embodiment B. Figure 5(b) is a front view of the recording device 1.

[0057] Example B shows the optimal arrangement of the sheet guide ribs 200 and the output tray 17 when the sheet SH4 is curled in an upward convex shape. For example, Example B can be applied when the recording method is an inkjet method and face-up output is used, where the printed surface is located above in the Z direction. The sheet guide ribs 200 are positioned in the center of the width direction of the sheet SH4. In this specification, the sheet guide ribs 200 guide the central portion of the sheet SH4 in the width direction (X direction). The cross-sectional shape (XZ cross-sectional shape) of the sheet guide ribs 200 in the width direction (X direction) of the sheet SH4 is rectangular, but it may be a tapered shape or a V-shape, similar to Example A. The substantially horizontal surface 17d of the output tray 17 is located at both ends of the width of the sheet SH4. Surface 17e is positioned directly below the sheet guide ribs 200 in the Z direction in the center of the width of the sheet SH4. In this specification, surface 17e is referred to as a "recess" located directly below the sheet guide rib 200 that is on the frontmost side of the scanner unit 900 (upper housing) among the sheet guide ribs 200. Here, the substantially horizontal surface 17d relative to the "recess" may be referred to as a "convex portion".

Figure 6(b) is a diagram illustrating the internal configuration of the recording device 1 according to the second embodiment. In Figures 6(a) and 6(b), the same reference numerals are used for components similar to those in the first embodiment, so their descriptions are omitted.

[0059] (Regarding the overall configuration of the second embodiment) In the first embodiment, the scanner unit 900 is provided above the housing 101, but this is not the only embodiment. For example, in the second embodiment, a cover member 300 is arranged above the housing 101 as an upper housing.
