DETAILED DESCRIPTION OF THE INVENTION

[0009] <Embodiment> Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0010] <Overview of Image Reading Apparatus According to an Embodiment> First, an overview of the image reading apparatus according to the embodiment will be described.

[0011] An image reading device according to an embodiment is attached to a printing device and reads an image from a medium from which the image is to be read. The image reading device includes a feed tray, a transport unit, an image reading unit, a discharge tray, and a housing. The feed tray is a tray on which a medium is placed. The transport unit transports the medium placed on the feed tray from the feed tray. The image reading unit reads an image from the medium transported by the transport unit. The discharge tray is where the medium is discharged after the image has been read by the image reading unit. The housing houses the transport unit and the image reading unit. Here, the feed tray and the discharge tray are removable in a pull-out direction. In this image reading device, when one of the feed tray and the discharge tray moves in the pull-out direction, the other of the feed tray and the discharge tray moves in the pull-out direction. This reduces the user's effort in pulling out the feed tray and the discharge tray separately, thereby improving user convenience.

[0012] The configuration of the image reading apparatus according to the embodiment will be described in detail below.

[0013] <Configuration of image reading device according to embodiment> The configuration of the image reading device according to the embodiment will be described below by taking the image reading device 1 as an example.

[0014] In the following embodiments, for ease of explanation, a user of the image reading device 1 will be referred to simply as a user. In this specification, the three-dimensional coordinate system TC is a three-dimensional Cartesian coordinate system that indicates directions in a drawing in which the three-dimensional coordinate system TC is depicted. In the following, for ease of explanation, the X-axis in the three-dimensional coordinate system TC will be referred to simply as the X-axis. In the following, for ease of explanation, the Y-axis in the three-dimensional coordinate system TC will be referred to simply as the Y-axis. In the following, for ease of explanation, the Z-axis in the three-dimensional coordinate system TC will be referred to simply as the Z-axis. In the following, as an example, a case will be described in which the negative direction of the Z-axis coincides with the direction of gravity. Therefore, in the following, for ease of explanation, the positive direction of the Z-axis will be referred to as the upward direction or simply "up," and the negative direction of the Z-axis will be referred to as the downward direction or simply "down." In the following, for ease of explanation, the positive direction of the X-axis will be referred to as the forward direction or simply "forward," and the negative direction of the X-axis will be referred to as the backward direction or simply "rear."

[0015] For ease of explanation, the surface of an object on the positive side of the X axis will be referred to as the front surface of the object, and the surface of the object on the negative side of the X axis will be referred to as the rear surface of the object. Also, the case where an object is viewed from a certain direction will be referred to as the case where the object is viewed from that direction.

[0016] FIG. 1 is a perspective view showing an example of the appearance including the front surface of an image reading device 1 according to an embodiment.

[0017] As shown in FIG. 1, image reading device 1 is attached to printing device 2 and reads an image from medium CP1, which is the target of image reading. Note that image reading device 1 may or may not be included in printing device 2. Furthermore, printing device 2 is, for example, an inkjet printer, but may instead be another type of printer. In the example shown in FIG. 1, when printing device 2 is viewed vertically, printing medium CP1 is transported parallel to the X-axis and prints an image on the transported printing medium. Medium CP1 is, for example, a printing medium on which an image is printed, but is not limited to this. Below, as an example, a case will be described in which medium CP1 is A4-sized printing paper on which an image is printed.

[0018] 2 is a side cross-sectional view showing an example of the configuration of the image reading device 1 attached to the printing device 2. In FIG. 2, a side cross-sectional view showing an example of the configuration of the printing device 2 is shown together with a side cross-sectional view of the image reading device 1.

[0019] 2, the image reading device 1 includes a housing BX, a feed-side mounting unit PM1, a conveying unit R1, a feed tray DS, an image reading unit SC, a discharge-side mounting unit PM2, and a discharge tray ST. Note that the image reading device 1 may include other members in addition to the housing BX, the feed-side mounting unit PM1, the conveying unit R1, the feed tray DS, the image reading unit SC, the discharge-side mounting unit PM2, and the discharge tray ST.

[0020] The housing BX has a generally rectangular parallelepiped shape overall and houses the various components of the image reading device 1. Therefore, the housing BX houses the feed-side placement unit PM1, the transport unit R1, the feed tray DS, the image reading unit SC, the discharge-side placement unit PM2, and the discharge tray ST. The housing BX may have other shapes. Furthermore, the housing BX may be configured not to house some or all of the feed-side placement unit PM1, the feed tray DS, the discharge-side placement unit PM2, and the discharge tray ST.

[0021] The feeding-side mounting part PM1 is a member having a feeding-side mounting surface PMM1 on which one or more media CP1 are placed.

[0022] The transport unit R1 is a member that transports the medium CP1 in a predetermined transport direction. In the example shown in FIG. 1, the transport unit R1 has two rollers. Of these two rollers, the roller located upstream in the transport direction is a pickup roller. Of these two rollers, the roller located upstream in the transport direction is a separation roller. The transport unit R1 transports the medium CP1 placed on the feed-side mounting surface PMM1 of the feed-side mounting unit PM1 one by one in the transport direction using these two rollers. Note that instead of the pickup roller and separation roller, the transport unit R1 may be configured to include other members that can transport the medium CP1 placed on the feed-side mounting surface PMM1 of the feed-side mounting unit PM1 one by one in the transport direction. Also, for convenience of explanation, the downstream end of an object in the transport direction will be referred to as the downstream end of the object, and the upstream end of the object in the transport direction will be referred to as the upstream end of the object. The downstream end of the object is the end of the object that is on the downstream side in the conveying direction, and the upstream end of the object is the end of the object that is on the upstream side in the conveying direction.

[0023] Here, when the image reading device 1 is viewed from a direction perpendicular to the feed-side mounting surface PMM1, the transport direction is parallel to the direction in which the printing device 2 transports the print medium. In the example shown in FIG. 2, this direction is, for example, the vertical direction. Therefore, in this case, the direction in which the printing device 2 transports the print medium is parallel to the X-axis, as described above. Therefore, in this case, the transport direction is also parallel to the X-axis. The dotted line PT shown in FIG. 2 indicates a portion of the path through which the medium CP1 transported by the transport unit R1 passes. The transport direction may also be a direction along the X-axis. Furthermore, the transport direction may be expressed as a direction along the negative direction of the X-axis. In this case, the transport direction is the direction in which the medium CP1 transported by the transport unit R1 transports the medium CP1 along the negative direction of the X-axis on the path through which the medium CP1 passes. In this case, the direction in which the medium CP1 transports in the positive direction of the X-axis after passing through a portion of the path where the medium CP1 curves and changes direction may be expressed as the direction opposite to the transport direction.

[0024] The feed tray DS is a member that supports the medium CP1 together with the feed-side mount part PM1. The feed tray DS is located above the discharge tray ST. The feed tray DS is a tray that can be pulled out in a predetermined pull-out direction. By pulling out the feed tray DS in the pull-out direction, the surface that supports the medium CP1 can be expanded together with the feed-side mount surface PMM1 of the feed-side mount part PM1. Therefore, the pull-out direction is parallel to the transport direction. Here, in the example shown in Figures 1 and 2, the medium CP1 is transported from the feed-side mount part PM1 toward the negative side of the X axis. In this case, the pull-out direction coincides with the positive side of the X axis. In other words, the pull-out direction is the direction opposite to the direction in which the medium CP1 is transported from the feed-side mount part PM1. In other words, in this case, the pull-out direction is the direction from the rear surface of the housing BX toward the front surface of the housing BX. This means that the pull-out direction intersects with the front surface of the housing BX and extends in a direction from the rear surface of the housing BX toward the front surface of the housing BX.

[0025] More specifically, the feed tray DS can be moved from a first state to a second state by being pulled out in the pull-out direction. Here, the first state refers to a state in which the feed tray DS is located at a predetermined first position above the feed-side mounting surface PMM1 and accommodated in the housing BX. Meanwhile, the second state refers to a state in which the feed tray DS is located at a predetermined second position where the feed tray DS supports the medium CP1 together with the feed-side mounting part PM1. The state of the feed tray DS shown in FIG. 2 is the second state. That is, the position of the feed tray DS shown in FIG. 2 is an example of the second position. Therefore, in the example shown in FIG. 2, the feed tray DS is connected to the feed-side mounting surface PMM1 of the feed-side mounting part PM1 and supports the medium CP1 together with the feed-side mounting part PM1. The feed tray DS may also be referred to as a document support. The joint between the upper surface of the feed tray DS and the feed-side mounting surface PMM1 may or may not have a step. Furthermore, if the joint between the upper surface of the feed tray DS and the feed-side mounting surface PMM1 has a step, the downstream end of the upper surface of the feed tray DS may be located above the upstream end of the feed-side mounting surface PMM1, or may be located below the upstream end of the feed-side mounting surface PMM1.

[0026] The image reading unit SC reads an image from the medium CP1 transported by the transport unit R1. In other words, the image reading unit SC is a scanner. More specifically, the image reading unit SC has a glass surface and reads an image from the medium CP1 passing over the glass surface. When the image reading unit SC is used as a flatbed scanner, the components of the image reading unit SC that are located on the glass surface are opened to expose the glass surface, and the medium CP1 is set on the exposed glass surface. This allows the image reading unit SC to read an image from the medium CP1 set on the glass surface.

[0027] The discharge-side mounting part PM2 is a tray onto which the medium CP1 is discharged after the image has been read by the image reading unit SC. More specifically, the discharge-side mounting part PM2 is a member having a discharge-side mounting surface PMM2 on which one or more sheets of medium CP1 are placed.

[0028] The discharge tray ST is a member that supports the medium CP1 together with the discharge-side mounting part PM2. The discharge tray ST is a tray that can be pulled out in the aforementioned pull-out direction, and by pulling it out in the pull-out direction, the surface that supports the medium CP1 can be expanded together with the discharge-side mounting surface PMM2 of the discharge-side mounting part PM2.

[0029] More specifically, the discharge tray ST can be moved from the third state to the fourth state by being pulled out in the pull-out direction. Here, the third state refers to a state in which the discharge tray ST is located at a predetermined third position above the discharge-side placement surface PMM2, where the discharge tray ST is accommodated in the housing BX. Meanwhile, the fourth state refers to a state in which the discharge tray ST is located at a predetermined fourth position, where the discharge tray ST supports the medium CP1 together with the discharge-side placement surface PMM2. The state of the discharge tray ST shown in FIG. 2 is the fourth state. That is, the position of the discharge tray ST shown in FIG. 2 is an example of the fourth position. Therefore, in the example shown in FIG. 2, the discharge tray ST is connected to the discharge-side placement surface PMM2 of the discharge-side placement unit PM2 and supports the medium CP1 together with the discharge-side placement unit PM2. The discharge tray ST may also be referred to as a stacker. Furthermore, the positional relationship between the feed tray DS and the discharge tray ST is not limited to the positional relationship between the feed tray DS and the discharge tray ST shown in FIG. 2. Therefore, the discharge tray ST may be configured to be located above the feed tray DS, which means that the image reading device 1 is configured to feed paper from below and discharge paper from above.

[0030] Meanwhile, the printing device 2 includes a paper feed tray TR, a transport unit R2, a printing unit C, a discharge tray ET, an operation unit, and ink tanks. The operation unit may also be referred to as an operation panel. In the printing device 2, the operation unit, ink tanks, and discharge tray ET are each located on the surface of the printing device 2 that receives operations from the user, i.e., on the front side of the printing device 2. This allows the user to operate the printing device 2 from the front side of the printing device 2. This means that the user does not need to go around to the side or back of the printing device 2 when operating the printing device 2, which is useful and leads to improved usability.

[0031] The paper feed tray TR is a tray on which the print medium CP2 is placed. The medium CP2 is, for example, A4-sized printing paper, but may instead be other media on which images can be printed, such as a sticker mount. The discharge tray ET can be pulled out in a pull-out direction, which is the direction from the rear surface of the housing BX toward the front surface of the housing BX. In other words, the discharge tray ET can be pulled out in the same direction as the discharge tray ST and the feed tray DS provided in the image reading device 1.

[0032] The transport unit R2 transports the medium CP2 placed on the paper feed tray TR to the printing unit C. At this time, when the printing device 2 is viewed vertically, the transport unit R2 transports the medium CP2 to the printing unit C parallel to the X axis.

[0033] The printing unit C prints an image on the medium CP2 transported by the transport unit R2. The printing unit C includes, for example, a carriage C1, a print head C2, and a platen C3.

[0034] The carriage C1 carries the print head C2 and moves the print head C2 back and forth along a predetermined scanning direction. The scanning direction is a direction that intersects with the transport direction when the image reading device 1 is viewed from a direction perpendicular to the feed-side mounting surface PMM1. In the example shown in Figure 2, the scanning direction is a direction perpendicular to the transport direction in this case, i.e., a direction parallel to the Y axis.

[0035] The print head C2 prints an image onto a medium CP2 passing between the print head C2 and a platen C3. In this example, the print head C2 is, for example, an inkjet print head, but is not limited to this.

[0036] The platen C3 supports the medium CP2 transported by the transport unit R2 below the path along which the print head C2 moves.

[0037] The discharge tray ET is a tray onto which the medium CP2 is discharged after an image is printed by the printing unit C. The discharge tray ET can be pulled out in a pull-out direction, which is the direction from the rear of the housing BX toward the front of the housing BX. That is, the discharge tray ST and feed tray DS provided in the image reading device 1 and the discharge tray ET and feed tray TR on the printing device 2 side can be pulled out in the same direction. As a result, in the printing device 2 to which the image reading device 1 is attached, the user can operate each of the discharge tray ST, feed tray DS, discharge tray ET, and feed tray TR from the front side of the printing device 2, i.e., the front side of the image reading device 1. This means that whether the user is operating the image reading device 1 or the printing device 2, there is no need to go around to the side or back of the printing device 1 or the image reading device 1, which is useful and leads to improved usability.

[0038] In the image reading device 1 attached to the printing device 2 configured as described above, when one of the feed tray DS and the discharge tray ST moves in the pull-out direction, the other of the feed tray DS and the discharge tray ST also moves in the pull-out direction. This reduces the user's effort to pull out the feed tray DS and the discharge tray ST individually, thereby improving user convenience. The following describes the peripheral configuration of the feed tray DS and the discharge tray ST. For ease of explanation, the one tray will be referred to as the operation tray and the other tray will be referred to as the driven tray. In this case, for example, if the operation tray is the feed tray DS, the driven tray is the discharge tray ST. On the other hand, in this case, for example, if the operation tray is the discharge tray ST, the driven tray is the feed tray DS.

[0039] <Configuration of the feed tray and output tray> The following describes the configuration around the feed tray DS and discharge tray ST. Fig. 3 is a side view showing an example of the configuration of the feed tray DS and discharge tray ST. Fig. 3 shows the feed tray DS and discharge tray ST when viewed in the positive direction of the Y axis. In the example shown in Fig. 3, the operation tray is the discharge tray ST. In the example, the driven tray is the feed tray DS. For convenience of explanation, the case where the state of the feed tray DS is the first state and the state of the discharge tray ST is the third state will be described as the case where the state of the feed tray DS is the first state.

[0040] When viewed from a direction perpendicular to the feed-side placement surface PMM1, the feed tray DS can be displaced between a first state and a second state by sliding relative to the feed-side placement part PM1 in the direction parallel to the conveyance direction. Therefore, as described above, the feed tray DS can be displaced from the first state to the second state by pulling it out in the pull-out direction. This allows the user to displace the feed tray DS between the first state and the second state even when there is no free space above the image reading device 1. That is, the feed tray DS is provided in the housing BX so as to be slidable between the first position and the second position. To achieve this, the feed tray DS has, for example, a positioning target part EG2 that is positioned by a positioning part EG1 provided in the housing BX. Note that the feed tray DS may be configured to have a single positioning target part EG2 or two or more positioning target parts EG2. However, the number of positioning parts EG1 that position the positioning target parts EG2 is the same as the number of positioning target parts EG2.

[0041] In the example shown in FIG. 3, the feed tray DS has two positioned portions EG2. That is, in this example, a positioned portion EG2 is provided at each of the ends of the feed tray DS in the direction parallel to the Y axis. These two positioned portions EG2 face each other in the direction parallel to the Y axis and have the same configuration. Therefore, hereinafter, the configuration of the positioned portion EG2 on the negative side of the Y axis will be described as an example of the configuration of these two positioned portions EG2.

[0042] The positioned portion EG2 has a first engaged portion EG21 and a second engaged portion EG22 that are aligned parallel to the pull-out direction when the feed tray DS is in the first state. In the example shown in FIG. 3, the first engaged portion EG21 is located downstream of the second engaged portion EG22 in the pull-out direction when viewed from a direction perpendicular to the feed-side placement surface PMM1. The first engaged portion EG21 and the second engaged portion EG22 are cylindrical protrusions that protrude from the feed tray DS in a direction perpendicular to the pull-out direction. In other words, the first engaged portion EG21 and the second engaged portion EG22 are cylindrical protrusions that protrude from the feed tray DS in the negative direction of the Y axis. In this example, the first engaged portion EG21 is spaced apart from the second engaged portion EG22. However, the first engaged portion EG21 may be connected to the second engaged portion EG22. In FIG. 3, the positioned portion EG2 on the positive side of the Y axis among the positioned portions EG2 of the feed tray DS is hidden behind the main body of the feed tray DS and is not visible.

[0043] FIG. 4 is a side cross-sectional view of the image reading device 1 shown in FIG. 3, cut away so as to show the appearance of the positioning unit EG1. However, in FIG. 4, the feed tray DS is omitted to clearly show the configuration of the positioning unit EG1. In the example shown in FIG. 4, a positioning unit EG1 is provided on each of two of the inner walls of the housing BX that intersect with the Y-axis. That is, in this example, the housing BX has two positioning units EG1. This is because, as described above, the feed tray DS has two positioned units EG2. These two positioning units EG1 face each other in a direction parallel to the Y-axis and have the same configuration. Therefore, the configuration of the positioning unit EG1 on the positive side of the Y-axis will be described below as an example of the configuration of these two positioning units EG1.

[0044] When the positioned portion EG2 has a first engaged portion EG21 and a second engaged portion EG22, the positioning portion EG1 has, for example, a first engaging portion EG11 and a second engaging portion EG12. In the example shown in FIG. 4, the first engaging portion EG11 is located above the feeding-side mounting surface PMM1 and extends in a direction parallel to the drawing direction. In this example, the downstream end of the first engaging portion EG11 engages with the first engaged portion EG21 of the feeding tray DS in the first state. In this example, the second engaging portion EG12 is the upstream end of the first engaging portion EG11 and engages with the second engaged portion EG22 of the feeding tray DS in the second state. In this example, the positioning member EG1 includes a first engaging member EG11 and a second engaging member EG12, as well as a third engaging member EG13 that engages with the first engaged member EG21 when the second engaging member EG12 and the second engaged member EG22 are engaged. The third engaging member EG13 is located below the second engaging member and downstream of the second engaging member EG12 in the conveyance direction. More specifically, the third engaging member EG13 is a recess formed downward from the first engaging member EG11. Therefore, when the third engaging member EG13 and the first engaged member EG21 engage with each other, the first engaged member EG21 is caught by the third engaging member EG13, preventing the feed tray DS from sliding in the conveyance direction due to gravity. In other words, the image reading device 1 can fix the position of the feed tray DS even when the feed tray DS is tilted.

[0045] FIG. 5 is a side cross-sectional view showing the feed tray DS when the first engagement portion EG21 and the third engagement portion EG13 are engaged. In the example shown in FIG. 5, the first engagement portion EG21 is engaged with the third engagement portion EG13. Also, in this example, the second engagement portion EG22 is engaged with the second engagement portion EG12. This allows the image reading device 1 to tilt the top surface of the feed tray DS. For example, a user can slide the feed tray DS in the pull-out direction to engage the second engagement portion EG22 with the second engagement portion EG12, thereby putting the feed tray DS in the second state, and then lift the upstream end of the feed tray DS to engage the first engagement portion EG21 with the third engagement portion EG13. This is useful because it allows the medium CP1 to slide downstream in the transport direction due to gravity.

[0046] Here, the feed tray DS has a feed-side flat portion DS11 having a flat surface on which the medium CP1 is placed, and a feed-side protrusion DS12 that protrudes vertically from the upstream end of the feed-side flat portion DS11 when the feed tray DS is in the first state. In the example shown in Fig. 3, the feed-side protrusion DS12 is a flat member that, in this state, forms part of the front surface of the image reading device 1. On the other hand, the discharge tray ST has a discharge-side flat portion ST11 having a flat surface on which the medium CP1 is placed, and a discharge-side protrusion ST12 that protrudes in the opposite direction to the vertical from the upstream end of the discharge-side flat portion ST11 in this state.

[0047] As shown in FIG. 3, at least a portion of the feed-side protrusion DS12 overlaps with the discharge-side protrusion ST12 in the pull-out direction. Specifically, the feed-side protrusion DS12 and the discharge-side protrusion ST12 are arranged in the order of discharge-side protrusion ST12, feed-side protrusion DS12, in the pull-out direction. In the example shown in FIG. 3, when the feed tray DS is in the first state, the feed-side protrusion DS12 is in contact with the discharge-side protrusion ST12. Therefore, as the discharge tray ST moves in the pull-out direction, the discharge-side protrusion ST12 pushes the feed-side protrusion DS12, thereby moving the feed tray DS in the pull-out direction. Therefore, in the image reading device 1 shown in FIG. 3, a user can pull out the feed tray DS together with the discharge tray ST by pulling out the discharge tray ST in the pull-out direction. As a result, the image reading device 1 can reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience. In this case, the feed-side protrusion DS12 may be configured to be separated from the discharge-side protrusion ST12. Even in this case, as long as at least a portion of the feed-side protrusion DS12 overlaps with the discharge-side protrusion ST12 in the pulling direction, the discharge-side protrusion ST12 can move the feed tray DS in the pulling direction in response to movement of the discharge tray ST in the pulling direction. However, when the feed tray DS is in the first state and the feed-side protrusion DS12 is in contact with the discharge-side protrusion ST12, the user can always coordinate the movement of the discharge tray ST and the movement of the feed tray DS when pulling out the discharge tray ST in the pulling direction. As a result, the image reading device 1 can reduce the user's operational burden.

[0048] Fig. 6 is a perspective view showing an example of a feed tray DS that is pulled out in the pull-out direction together with the discharge tray ST by pulling out the discharge tray ST in the pull-out direction. As shown in Fig. 6, when the discharge tray ST is pulled out in the pull-out direction, the feed tray DS is also pushed by the discharge tray ST and pulled out in the pull-out direction. This allows the image reading device 1 to reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience.

[0049] In the example shown in FIG. 6, the surface of the feed tray DS facing the drawing direction has an opening HL. The opening HL does not overlap with the discharge-side protrusion ST12 in the drawing direction. Therefore, when pulling out the discharge-side protrusion ST12 in the drawing direction, the user can hook their finger on the discharge tray ST through the opening HL. As a result, the image reading device 1 makes it easy for the user to pull out the discharge tray ST. Furthermore, when lifting the feed tray DS in the second state, the user can hook their finger on the feed tray DS through the opening HL. As a result, the image reading device 1 makes it easy for the user to lift the feed tray DS. FIG. 7 is a perspective view showing an example of the upstream end of the feed tray DS in the second state lifted upward. In the feed tray DS shown in FIG. 7, the first engagement portion EG21 is engaged with the third engagement portion EG13 described above. Therefore, in the example shown in FIG. 7, the feed tray DS is held with its upper surface tilted.

[0050] 6, the feed-side protrusion DS12 also functions as an operation unit that allows the user to operate the feed tray DS when pushing the feed tray DS in the push-in direction, which is opposite to the pull-out direction. In this case, the user can push the feed tray DS and the discharge tray ST in the push-in direction by pushing the feed-side protrusion DS12 in the push-in direction. As a result, the image reading device 1 can reduce the user's effort to push the feed tray DS and the discharge tray ST separately, thereby further improving user convenience. Note that the operation unit may be separate from the feed-side protrusion DS12.

[0051] As shown in FIG. 3, the image reading device 1 further includes a biasing member SP1 that biases the discharge tray ST in the pull-out direction, and a restricting portion LM1 that restricts the movement of the discharge tray ST.

[0052] The restricting unit LM1 restricts the movement of the discharge tray ST in the pull-out direction when the state of the feed tray DS is in the first state. The restricting unit LM1 releases the restriction on the movement of the discharge tray ST by the restricting unit LM1 in response to an operation received from the user. The restricting unit LM1 may have any configuration as long as it is capable of restricting the movement of the discharge tray ST in this case and releasing the restriction in response to the operation. For this reason, FIG. 3 illustrates the restricting unit LM1 as a rectangular object. Here, the user's operation received by the restricting unit LM1 includes, for example, applying a force of a predetermined magnitude or greater in the pull-out direction, receiving an instruction from the user to read an image from the medium CP1, etc., but is not limited to these. Note that when the user's operation received by the restricting unit LM1 is receiving an instruction from the user to read an image from the medium CP1, the restricting unit LM1 may be configured to at least one of restricting the movement of the discharge tray ST and releasing the restriction by a driving unit such as an actuator.

[0053] The biasing member SP1 may be any member capable of biasing the discharge tray ST in the pull-out direction when the feed tray DS is in the first state. The biasing member SP1 is, for example, a coil spring that biases the downstream end of the discharge tray ST in the pull-out direction. The biasing member SP1 is provided in the housing BX, and when the restriction on the movement of the discharge tray ST by the restricting member LM1 is released, moves the discharge tray ST in the pull-out direction relative to the housing BX. This allows the image reading device 1 to assist the user in pulling out the discharge tray ST in the pull-out direction. In other words, the image reading device 1 can reduce the force that the user applies to the discharge tray ST in order to pull out the feed tray DS together with the discharge tray ST in the pull-out direction.

[0054] The restricting portion LM1 may be configured to restrict movement of the feed tray DS in the pull-out direction when the feed tray DS is in the first state. In this case, the restricting portion LM1 releases the restriction on movement of the feed tray DS by the restricting portion LM1 in response to an operation received from the user. This also allows the image reading device 1 to assist the user in pulling out the discharge tray ST in the pull-out direction. This is because the restriction restricts movement of the discharge tray ST in the pull-out direction as well as movement of the feed tray DS in the pull-out direction. This is because the discharge-side protrusion ST12 and the feed-side protrusion DS12 overlap in the pull-out direction and are in contact with each other when the feed tray DS is in the first state. The biasing member SP1 may be configured to bias the feed tray DS in the pull-out direction when the feed tray DS is in the first state. Even in this case, the biasing member SP1 is provided on the housing BX, and when the restriction on movement of the discharge tray ST or the feed tray DS by the restricting member LM1 is released, the biasing member SP1 moves the feed tray DS in the pull-out direction relative to the housing BX. This allows the image reading device 1 to assist the user in pulling out the discharge tray ST in the pull-out direction. In other words, the image reading device 1 can reduce the force that the user applies to the feed tray DS in order to pull out the discharge tray ST together with the feed tray DS in the pull-out direction.

[0055] As described above, in the image reading device 1, the feed tray DS moves in the pull-out direction in response to the movement of the discharge tray ST in the pull-out direction. This allows the image reading device 1 to reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience.

[0056] <First Modification of the Embodiment> A first modification of the embodiment will be described below. In the image reading device 1 according to the first modification of the embodiment, the discharge tray ST moves in the pull-out direction in response to the movement of the feed tray DS in the pull-out direction. That is, in the first modification of the embodiment, the operation tray is the feed tray DS. Also, in the first modification of the embodiment, the driven tray is the discharge tray ST.

[0057] Fig. 8 is a side view showing another example of the configuration of the feed tray DS and the discharge tray ST. In the example shown in Fig. 8, the feed tray DS has a feed-side protrusion DS13 instead of the feed-side protrusion DS12.

[0058] As shown in FIG. 8, at least a portion of the feed-side protrusion DS13 overlaps with the discharge-side protrusion ST12 in the pull-out direction. Specifically, the feed-side protrusion DS13 and the discharge-side protrusion ST12 are arranged in this order in the pull-out direction. In the example shown in FIG. 8, when the feed tray DS is in the first state, the feed-side protrusion DS13 contacts the discharge-side protrusion ST12. Therefore, as the feed tray DS moves in the pull-out direction, the feed-side protrusion DS13 pushes the discharge-side protrusion ST12, thereby moving the discharge tray ST in the pull-out direction. Therefore, in the image reading device 1 shown in FIG. 8, a user can pull out the feed tray DS in the pull-out direction and then pull out the discharge tray ST together. As a result, the image reading device 1 can reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience. In this case, the discharge-side protrusion ST12 may be configured to be separated from the feed-side protrusion DS13. Even in this case, as long as at least a portion of the feed-side protrusion DS13 overlaps with the discharge-side protrusion ST12 in the pull-out direction, the feed-side protrusion DS13 can move the discharge tray ST in the pull-out direction in response to movement of the feed tray DS in the pull-out direction. However, when the feed tray DS is in the first state and the feed-side protrusion DS13 is in contact with the discharge-side protrusion ST12, the user can always coordinate the movement of the discharge tray ST and the movement of the feed tray DS when pulling out the feed tray DS in the pull-out direction. As a result, the image reading device 1 can reduce the user's operational burden.

[0059] FIG. 9 is a perspective view showing an example of a state in which the feed tray DS in the image reading device 1 according to the first modification of the embodiment is in the first state. As shown in FIG. 9, the feed-side protrusion DS13 has a recess DP. The discharge-side protrusion ST12 fits into the recess DP in response to movement in the pushing direction. The state of the discharge-side protrusion ST12 shown in FIG. 9 is a state in which it is fitted into the recess DP. In addition, in the example shown in FIG. 9, the surface of the discharge-side protrusion ST12 that fits into the recess DP on the drawing direction side is included in a virtual plane that includes the surface of the feed-side protrusion DS12 on the drawing direction side. In other words, in this example, the surface of the discharge-side protrusion ST12 that fits into the recess DP on the drawing direction side is flush with the surface of the feed-side protrusion DS12 on the drawing direction side. This prevents unnecessary irregularities from appearing on the exterior of the image reading device 1 when the state of the feed tray DS is in the first state, and as a result, prevents the image reading device 1 from getting caught on other objects such as the user's finger. This is also useful as it leads to a reduction in the size of the image reading device 1.

[0060] In the example shown in FIG. 9 , the upper surface of the feed tray DS, i.e., the upper surface of the feed-side flat surface DS11, is provided with a gripping portion HL2 that can be gripped to move the feed tray DS in the pull-out direction. This allows the image reading device 1 to easily pull the feed tray DS in the pull-out direction by a user. The gripping portion HL2 may have any configuration as long as it can be gripped to move the feed tray DS in the pull-out direction. In this example, the gripping portion HL2 is an opening on the upper surface of the feed tray DS, i.e., the upper surface of the feed-side flat surface DS11. In this case, the image reading device 1 allows the user to pull the feed tray DS in the pull-out direction by hooking their finger, thereby improving the usability of the image reading device 1. Furthermore, when the gripping portion HL2 is an opening, the image reading device 1 does not need to have the gripping portion HL2 protrude outward from the housing BX, thereby preventing the image reading device 1 from becoming larger due to the gripping portion HL2. The gripping portion HL2 may be provided at another location on the feed tray DS instead of on the top surface of the feed tray DS.

[0061] 10 is a diagram showing an example of the discharge tray ST being pulled out in the pull-out direction together with the feed tray DS by pulling out the feed tray DS in the pull-out direction. As shown in FIG. 10, when the feed tray DS is pulled out in the pull-out direction, the discharge tray ST is also pushed by the feed tray DS and pulled out in the pull-out direction. This allows the image reading device 1 to reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience.

[0062] Furthermore, when lifting the feed tray DS in the second state upward, the user can hook their fingers on the feed tray DS through the grip portion HL2. As a result, the image reading device 1 makes it easy for the user to lift the feed tray DS. FIG. 11 is a perspective view showing another example of the state in which the upstream end of the feed tray DS in the second state is lifted upward. In the feed tray DS shown in FIG. 11, the first engaged portion EG21 is engaged with the third engaging portion EG13 described above. Therefore, in the example shown in FIG. 11, the feed tray DS is held with its upper surface tilted.

[0063] 10, the discharge-side protrusion ST12 also functions as an operation unit that allows the user to operate the discharge tray ST when pushing the discharge tray ST in the push-in direction. In this case, the user can push the discharge tray ST together with the feed tray DS in the push-in direction by pushing the discharge tray ST in the push-in direction. As a result, the image reading device 1 can reduce the user's effort to push the feed tray DS and the discharge tray ST separately, thereby more reliably improving user convenience. Note that the operation unit may be separate from the discharge-side protrusion ST12.

[0064] 8, the image reading device 1 also includes a biasing member SP1 that biases the discharge tray ST in the pull-out direction and a restricting portion LM1 that restricts movement of the discharge tray ST. This allows the image reading device 1 to assist the user in pulling out the feed tray DS in the pull-out direction. In other words, the image reading device 1 can reduce the force that the user applies to the feed tray DS in order to pull out the discharge tray ST together with the feed tray DS in the pull-out direction.

[0065] The restricting portion LM1 may be configured to restrict movement of the feed tray DS in the pull-out direction when the feed tray DS is in the first state. In this case, the restricting portion LM1 releases the restriction on movement of the feed tray DS by the restricting portion LM1 in response to an operation received from the user. This also allows the image reading device 1 to assist the user in pulling out the feed tray DS in the pull-out direction. This is because the restriction restricts movement of the discharge tray ST in the pull-out direction as well as movement of the feed tray DS in the pull-out direction. This is because the discharge-side protrusion ST12 and the feed-side protrusion DS13 overlap in the pull-out direction and are in contact with each other when the feed tray DS is in the first state.

[0066] Furthermore, the biasing member SP1 may be configured to bias the feed tray DS in the pull-out direction when the feed tray DS is in the first state. Even in this case, the biasing member SP1 is provided on the housing BX, and moves the feed tray DS in the pull-out direction relative to the housing BX when the restriction on the movement of the discharge tray ST or the feed tray DS by the restricting member LM1 is released. This allows the image reading device 1 to assist the user in pulling out the feed tray DS in the pull-out direction. In other words, the image reading device 1 can reduce the force that the user applies to the feed tray DS in order to pull out the discharge tray ST together with the feed tray DS in the pull-out direction.

[0067] As described above, in the image reading device 1 according to the first modified example of the embodiment, the discharge tray ST moves in the pull-out direction in response to the movement of the feed tray DS in the pull-out direction. This allows the image reading device 1 to reduce the user's effort of pulling out the feed tray DS and the discharge tray ST separately, thereby improving user convenience.

[0068] <Modification 2 of the embodiment> A second variation of the embodiment will be described below. The second variation of the embodiment is a combination of the first variation of the embodiment and the first variation of the embodiment. Specifically, in the second variation of the embodiment, the image reading device 1 has a portion where the feed tray DS and the discharge tray ST overlap in the order of the feed tray DS and the discharge tray ST in the pull-out direction, and a portion where the feed tray DS and the discharge tray ST overlap in the order of the discharge tray ST and the feed tray DS in the pull-out direction. This allows the image reading device 1 to pull out the feed tray DS and the discharge tray ST in the pull-out direction by pulling out the feed tray DS in the pull-out direction, and also allows the feed tray DS and the discharge tray ST to be pulled out in the pull-out direction by pulling out the discharge tray ST in the pull-out direction. As a result, the image reading device 1 can more reliably improve user convenience.

[0069] <Modification 3 of the embodiment> A third variation of the embodiment will be described below. The third variation of the embodiment includes a movement mechanism MV that moves the driven tray in the pull-out direction in response to movement of the operation tray in the pull-out direction. As a result, the image reading device 1 moves both the supply tray DS and the discharge tray ST in the pull-out direction regardless of whether the supply tray DS or the discharge tray ST is treated as the operation tray. Therefore, the image reading device 1 can reduce the user's effort in pulling out the supply tray and the discharge tray separately, thereby improving user convenience.

[0070] Fig. 12 is a side view showing yet another example of the configuration of the supply tray DS and the discharge tray ST. In the example shown in Fig. 12, the supply tray DS has a first interlocking portion RK1 that extends in the pull-out direction when the supply tray DS is in the first state. In addition, in this example, the discharge tray ST has a second interlocking portion RK2 that extends in the pull-out direction in this state. In addition, in this example, the second interlocking portion RK2 is provided at a position opposite to the first interlocking portion RK1.

[0071] Here, the moving mechanism MV is a mechanism that meshes with the first meshing portion RK1 and the second meshing portion RK2, respectively, and moves the driven tray in the pull-out direction in response to movement of the manipulation tray in the pull-out direction. The moving mechanism MV may be any mechanism that meshes with the first meshing portion RK1 and the second meshing portion RK2, respectively, and is capable of moving the driven tray in the pull-out direction in response to movement of the manipulation tray in the pull-out direction. In the example shown in FIG. 12, the moving mechanism MV has a gear train of two gears: a first gear G1 and a second gear G2 that meshes with the first gear G1. The first gear G1 meshes with the first meshing portion RK1. The second gear G2 meshes with the second meshing portion RK2. Therefore, when a user pulls out the manipulation tray in the pull-out direction, the driven tray is also pulled out in the pull-out direction by the drive of the gear train. This allows the image reading device 1 to more reliably reduce the user's operational burden. Furthermore, when the image reading device 1 is equipped with the movement mechanism MV, the movement distance of the operation tray and the driven tray can be adjusted by changing the specifications of the first meshing portion RK1, the second meshing portion RK2, the first gear G1, and the second gear G2. As a result, the image reading device 1 can change the sizes of the feed tray DS and the discharge tray ST according to the application, adjust the amount of protrusion of the feed tray DS and the discharge tray ST from the housing BX, and so on. This is useful because it improves the design flexibility of the image reading device 1.

[0072] In such a moving mechanism MV, at least a portion of the first gear G1 and at least a portion of the second gear G2 are housed in a housing BX, as shown in Fig. 13. Fig. 13 is a perspective view showing an example of how the first gear G1 and second gear G2 of the moving mechanism MV are housed in the housing BX. However, in Fig. 13, part of the housing BX and part of the feed tray DS are omitted in order to clearly show the first gear G1 and second gear G2 housed in the housing BX.

[0073] 13, the entire first gear G1 and the entire second gear G2 are housed in the housing BX. In this case, the image reading device 1 can prevent interference between the first gear G1 and the second gear G2 and other objects such as the medium CP1. Note that the image reading device 1 may be configured such that part or all of the first gear G1 is not housed in the housing BX. Also, the image reading device 1 may be configured such that part or all of the second gear G2 is not housed in the housing BX.

[0074] The items described above may be combined in any manner. For example, the feed tray DS according to the second modification of the embodiment may have the above-mentioned positioned portion EG2. In this case, the housing BX according to the second modification of the embodiment has a positioning portion EG1. This prevents the user from accidentally pushing the feed tray DS and the discharge tray ST in the push-in direction during printing when the feed tray DS in the second state is tilted and fixed in position. Furthermore, the image reading device 1 may be configured such that the discharge tray ST has the discharge-side protrusion ST12, and the feed tray DS does not have the feed-side protrusion DS12 or the feed-side protrusion DS13. In this case, at least a portion of the discharge-side protrusion ST12 overlaps with the feed tray DS in the pull-out direction. Furthermore, the image reading device 1 may be configured such that the feed tray DS has the feed-side protrusion DS12 or the feed-side protrusion DS13, and the discharge tray ST does not have the discharge-side protrusion ST12. In this case, at least a portion of the feed-side protrusion DS12 or the feed-side protrusion DS13 overlaps with the discharge tray ST in the pull-out direction. Furthermore, each of the feeding tray DS, conveying section R1, discharge tray ST, and housing BX described above may constitute a media conveying device that conveys the medium CP within the image reading device 1, or may constitute a media conveying device that conveys the medium to be conveyed independently of the image reading device 1.
