[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-167889 Summary of the Invention [Problem to be solved by the invention]

[0005] In an image reading device such as that described in Patent Document 1, the support unit is displaceable between a first state in which it is housed in a housing and a second state in which it supports a medium. In this image reading device, the support unit in the second state is connected to the mounting surface of the mounting unit. However, in this image reading device, when attempting to place a medium on the mounting surface by sliding it over the support unit in the second state, the edge of the mounting surface may come into contact with the medium, causing deformation of the medium. This is undesirable because it may cause the image reading device to malfunction. [Means for solving the problem]

[0006] In order to solve the above problem, one aspect of the present disclosure is to an image reading device that is attached to a printing device and reads an image from a medium from which an image is to be read, the image reading device comprising: a housing; a mounting section having a mounting surface on which the medium is placed; a transport section that transports the medium in a transport direction; a first guide section that is movable between a first state in which the mounting section is located in a storage position housed in the housing above the mounting section and a second state in which the first guide section is located in a support position that supports the medium together with the mounting section; and an image reading section that reads an image from the medium transported by the transport section, wherein the transport direction is parallel to the direction in which the printing device transports the print medium when viewed from a direction perpendicular to the mounting surface, and the first guide section in the second state slopes downward from upstream to downstream in the transport direction, and guides the medium transported by the transport section to a height that is higher than the upstream end of the mounting section in the transport direction, or to the same height as the upstream end of the mounting section in the transport direction.

[0008] <Embodiment> Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0009] <Overview of Image Reading Apparatus According to an Embodiment> First, an overview of the image reading apparatus according to the embodiment will be described.

[0010] 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 housing, a mounting unit, a transport unit, a first guide unit, and an image reading unit. The mounting unit has a mounting surface on which the medium is placed. The transport unit transports the medium in a transport direction. The first guide unit is a member that can be displaced between a first state in which it is located in a storage position above the mounting unit and housed in the housing, and a second state in which it is located in a support position in which it supports the medium together with the mounting unit. The image reading unit reads an image from the medium transported by the transport unit. Here, the transport direction is a direction parallel to the direction in which the printing device transports the print medium when viewed from a direction perpendicular to the mounting surface. In addition, in the second state, the first guide unit is inclined downward from upstream to downstream in the transport direction, and guides the medium transported by the transport unit to a height higher than the upstream end of the mounting unit in the transport direction, or to the same height as the upstream end of the mounting unit in the transport direction. This allows the image reading device to suppress deformation of the medium due to contact between the medium and the placement surface.

[0011] The configuration of the image reading apparatus according to the embodiment will be described in detail below.

[0012] <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.

[0013] 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."

[0014] For ease of explanation, the surface of image reading device 1 on the positive side of the X axis will be referred to as the front surface of image reading device 1, and the surface of image reading device 1 on the negative side of the X axis will be referred to as the rear surface of image reading device 1. In addition, the case where an object is viewed in a certain direction will be referred to as the case where the object is viewed in that direction.

[0015] 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.

[0016] 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 object of image reading. Printing device 2 is, for example, an inkjet printer, but may alternatively be another type of printer. In the example shown in FIG. 1, when printing device 2 is viewed vertically, printing device 2 transports the printing medium 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 has been 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 has been printed.

[0017] 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.

[0018] 2, the image reading device 1 includes a housing BX, a placement unit PM, a transport unit R1, a first guide unit GD1, an image reading unit SC, and an output tray ET1. Note that the image reading device 1 may include other members in addition to the housing BX, placement unit PM, transport unit R1, first guide unit GD1, image reading unit SC, and output tray ET1.

[0019] The housing BX has a generally rectangular parallelepiped shape overall and houses the components of the image reading device 1. Therefore, the housing BX houses the placement unit PM, the transport unit R1, the first guide unit GD1, the image reading unit SC, and the discharge tray ET1. However, the housing BX may have other shapes.

[0020] The receiver PM is a member having a receiver surface PMM on which one or more media CP1 are placed.

[0021] 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 separation rollers, and these two separation rollers transport the medium CP1 placed on the placement surface PMM of the receiver PM one by one in the transport direction. Note that instead of these two separation rollers, the transport unit R1 may be configured to have another member that can transport the medium CP1 placed on the placement surface PMM of the receiver PM 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 refers to the end of the object that is downstream in the transport direction. The upstream end of the object refers to the end of the object that is upstream in the transport direction.

[0022] Here, the transport direction is parallel to the direction in which the printing device 2 transports the print medium when viewed from a direction perpendicular to the placement surface PMM. 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 transports along the negative direction of the X-axis on the path through which the medium CP1 transported by the transport unit R1 passes. In this case, the direction in which the medium CP1 is transported 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.

[0023] The first guide part GD1 is a member that supports the medium CP1 together with the receiver part PM. The first guide part GD1 is also a member that can be displaced between a first state in which it is located at a predetermined storage position above the receiver surface PMM as a position where it is stored in the housing BX, and a second state in which it is located at a predetermined support position as a position where it supports the medium CP1 together with the receiver part PM. The state of the first guide part GD1 shown in FIG. 2 is the second state. Therefore, in the example shown in FIG. 2, the first guide part GD1 is connected to the receiver surface PMM of the receiver part PM and supports the medium CP1 together with the receiver part PM.

[0024] The image reading unit SC reads an image from the medium CP1 transported by the transport unit R1, that is, the image reading unit SC is a scanner.

[0025] The discharge tray ET1 is a tray onto which the medium CP1 is discharged after the image has been read by the image reading unit SC.

[0026] On the other hand, the printing device 2 includes a paper feed tray TR, a transport unit R2, a printing unit C, and a discharge tray ET2.

[0027] The paper feed tray TR is a tray on which the medium CP2 is placed as a print medium.

[0028] 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.

[0029] 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.

[0030] 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 viewed from a direction perpendicular to the mounting surface PMM. 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.

[0031] 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.

[0032] The platen C3 supports the medium CP2 transported by the transport unit R2 below the path along which the print head C2 moves.

[0033] The discharge tray ET2 is a tray onto which the medium CP2 is discharged after an image has been printed by the printing unit C.

[0034] In the image reading device 1 attached to the printing device 2 configured as described above, the first guide unit GD1 slopes downward from upstream to downstream in the transport direction, and guides the medium CP1 transported by the transport unit R1 to a height above the upstream end of the mounting unit PM or to the same height as the upstream end of the mounting unit PM. This allows the image reading device 1 to suppress deformation of the medium CP1 due to contact between the medium CP1 and the mounting surface PMM. The following describes the first guide unit GD1 and the configuration around the first guide unit GD1.

[0035] <Configuration of the first guide section and its surroundings> FIG. 3 is an enlarged view of the image reading device 1 shown in FIG. 1. In the example shown in FIG. 3, the first guide unit GD1 is accommodated in the housing BX. That is, the state of the first guide unit GD1 shown in FIG. 3 is the first state. In other words, the position of the first guide unit GD1 shown in FIG. 3 is an example of a accommodated position. Furthermore, when viewed from a direction perpendicular to the placement surface PMM, the first guide unit GD1 can be displaced between the first state and the second state by sliding relative to the placement surface PM in parallel with the conveyance direction. This allows the user to change the state of the first guide unit GD1 between the first state and the second state even if there is no free space above the image reading device 1. Because the first guide unit GD1 can be displaced between the first state and the second state, the housing BX has an engagement unit EG1 that engages with the first guide unit GD1. The first guide part GD1 has an engaged part EG2 that engages with the engaging part EG1, and can be pulled out from the housing BX in a predetermined pulling direction. In the example shown in FIG. 3, the pulling direction is the direction in which the first guide part GD1 in the first state slides relative to the housing BX. Below, as an example, a case will be described in which the pulling direction coincides with the positive direction of the X-axis. Furthermore, the housing BX may be configured to have a single engaging part EG1, or may be configured to have two or more engaging parts EG1. Note that the number of engaged parts EG2 that engage with the engaging part EG1 matches the number of engaging parts EG1.

[0036] FIG. 4 is a cross-sectional view of the image reading device 1 shown in FIG. 3, showing the appearance of the engaging portion EG1 and the engaged portion EG2. In the example shown in FIG. 4, an engaging portion EG1 is provided on each of two inner walls of the housing BX that intersect with the Y-axis. That is, in this example, the housing BX has two engaging portions EG1. These two engaging portions EG1 face each other in a direction parallel to the Y-axis and have the same configuration. Therefore, hereinafter, the configuration of the engaging portion EG1 on the positive side of the Y-axis will be described as an example of the configuration of these two engaging portions EG1. Note that when the housing BX has these two engaging portions EG1, engaged portions EG2 that engage with the engaging portion EG1 are provided on both ends of the first guide portion GD1 in a direction parallel to the Y-axis. That is, in this case, the first guide portion GD1 has two engaged portions EG2.

[0037] The engaging portion EG1 has a first engaging portion EG11 that engages with the engaged portion EG2 of the first guiding portion GD1 in the first state, and a second engaging portion EG12 that engages with the engaged portion EG2 of the first guiding portion GD1 in the second state. As described above, in this example, the drawing direction coincides with the positive direction of the X-axis. Therefore, the first engaging portion EG11 is located above the placement surface PMM and extends in a direction parallel to the drawing direction. In the example shown in FIG. 4, the engaged portion EG2 engages with the first engaging portion EG11 at the downstream end of the first engaging portion EG11. Also, in the example shown in FIG. 4, the second engaging portion EG12 extends from the upstream end of the first engaging portion EG11 downward and downstream in the conveying direction from the first engaging portion EG11. In other words, the second engagement portion EG12 is inclined downward from the upstream end of the first engagement portion EG11 toward a position downstream of the first engagement portion EG11 in the conveying direction.

[0038] 4 relative to the housing BX in the pull-out direction to engage the engaged portion EG2 with the second engaging portion EG12, thereby displacing the first guide portion GD1 from the first state to the second state. This allows the image reading device 1 to be shortened in both the length in the pull-out direction and the length in the width direction perpendicular to both the pull-out direction and the vertical direction, thereby achieving a more compact size.

[0039] FIG. 5 is a side cross-sectional view showing an example of the image reading device 1 when the first guide unit GD1 is in the second state. In FIG. 5, the engaged portion EG2 on the negative side of the Y axis of the engaged portion EG2 of the first guide unit GD1 is visible. In FIG. 5, the engaged portion EG2 on the positive side of the Y axis of the engaged portion EG2 of the first guide unit GD1 is hidden behind the main body of the first guide unit GD1 and is not visible. The engaged portion EG2 is engaged with the second engaging portion EG12 on the positive side of the Y axis of the second engaging portion EG12 of the housing BX. The engaged portion EG2 is located at the downstream end of the second engaging portion EG12. In this case, the engaged portion EG2 on the negative side of the Y axis of the engaged portion EG2 of the first guide unit GD1 is engaged with the second engaging portion EG12 on the negative side of the Y axis of the second engaging portion EG12 of the housing BX. Therefore, the state of the first guide portion GD1 shown in FIG. 5 is the second state.

[0040] In the example shown in FIG. 5 , a portion of the second engagement portion EG12 overlaps with the placement surface PMM when the second engagement portion EG12 is viewed in a direction parallel to the drawing direction. This allows the image reading device 1 to have a shorter vertical length of the housing BX compared to when the entire second engagement portion EG12 does not overlap with the placement surface PMM, thereby achieving a more compact size. The image reading device 1 may also be configured such that the entire second engagement portion EG12 overlaps with the placement surface PMM when viewed in a direction parallel to the drawing direction. In this case, the image reading device 1 can more reliably have a shorter vertical length of the housing BX compared to when the entire second engagement portion EG12 does not overlap with the placement surface PMM. The image reading device 1 may also be configured such that the entire second engagement portion EG12 does not overlap with the placement surface PMM when viewed in a direction parallel to the drawing direction. In this case, although it is not possible to reduce the size of the image reading device 1, it is possible to make the inclination of the upper surface of the first guide part GD1 in the second state steeper, which is useful because it leads to shortening the length of the image reading device 1 in the front-to-rear direction when the first guide part GD1 is in the second state.

[0041] Furthermore, the height of the downstream end of the first guide section GD1 in the second state is the height of a position located higher than the upstream end of the receiver PM, or the same height as the upstream end of the receiver PM. In the example shown in FIG. 5, the height of the downstream end of the first guide section GD1 in the second state is the height of a position located higher than the upstream end of the receiver PM. This allows the image reading device 1 to suppress deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM. This is because the medium CP1, which slides down the upper surface of the first guide section GD1 from a height equal to or higher than the height of the upstream end of the receiver PM and is placed on the receiver surface PMM, does not come into contact with the upstream end of the receiver PM in a direction parallel to the upper surface of the first guide section GD1.

[0042] 5, the distance X1 in the transport direction between the downstream end of the engaged portion EG2 and the downstream end of the first guide portion GD1 is equal to or greater than the distance X2 in the transport direction between the downstream end of the second engagement portion EG12 and the upstream end of the receiver PM. This allows the image reading device 1 to prevent a gap from forming between the downstream end of the first guide portion GD1 in the second state and the upstream end of the receiver PM. This is useful because it prevents the medium CP1 from getting into the gap between the downstream end of the first guide portion GD1 in the second state and the upstream end of the receiver PM. This also allows the image reading device 1 to more reliably prevent deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM.

[0043] The first guide portion GD1 may have a protrusion TH1 as shown in Fig. 6. Fig. 6 is a side cross-sectional view showing another example of the image reading device 1 when the first guide portion GD1 is in the second state.

[0044] The protrusion TH1 is located downstream of the center of the first guide section GD1 in the conveying direction and protrudes upward from the first guide section GD1. The protrusion TH1 guides the medium CP1 conveyed by the conveying section R1 to a height higher than the upstream end of the receiver PM or the same height as the upstream end of the receiver PM. In the example shown in FIG. 6, the height of the top of the protrusion TH1 is higher than the downstream end of the first guide section GD1, which is located higher than the upstream end of the receiver PM. Therefore, in this example, the image reading device 1 more reliably guides the medium CP1 conveyed by the conveying section R1 to a height higher than the upstream end of the receiver PM. As a result, the image reading device 1 can more reliably suppress deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM. Furthermore, when the first guide unit GD1 has the protrusion TH1, the image reading device 1 can guide the medium CP1 being conveyed by the conveying unit R1 to a height higher than the upstream end of the mounting unit PM or to the same height as the upstream end of the mounting unit PM, regardless of the inclination angle of the upper surface of the first guide unit GD1 in the second state and regardless of the height of the downstream end of the first guide unit GD1. As a result, the image reading device 1 can prevent problems such as poor conveyance of the medium CP1 and errors in reading the image from the medium CP1.

[0045] As described above, the image reading device 1 uses the first guide unit GD1 in the second state to guide the medium CP1 transported by the transport unit R1 to a height higher than the upstream end of the mounting unit PM or to the same height as the upstream end of the mounting unit PM, thereby enabling the image reading device 1 to suppress deformation of the medium CP1 due to contact between the mounting surface PMM and the medium CP1.

[0046] <First Modification of the Embodiment> A first modification of the embodiment will be described below. In the first modification of the embodiment, the engaged portion EG2 of the first guide portion GD1 has a first engaged portion EG21 and a second engaged portion EG22 that are aligned parallel to the conveying direction when the first guide portion GD1 is in the first state. FIG. 7 is a diagram showing another example of the configuration of the first guide portion GD1. In the example shown in FIG. 7, the first engaged portion EG21 is located downstream of the second engaged portion EG22 in the conveying direction when viewed from a direction perpendicular to the placement surface PMM. The first engaged portion EG21 and the second engaged portion EG22 are cylindrical protrusions that protrude from the first guide portion GD1 in a direction perpendicular to the conveying direction. 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. 7, the engaged portion EG2 on the positive side of the Y axis among the engaged portions EG2 of the first guide portion GD1 is hidden behind the main body of the first guide portion GD1 and cannot be seen.

[0047] When the engaged portion EG2 has a first engaged portion EG21 and a second engaged portion EG22, the first engaging portion EG11 and the second engaging portion EG12 are configured, for example, as shown in FIG. 8. FIG. 8 is a diagram showing another example of the engaging portion EG1 in the housing BX. As shown in FIG. 8, in Modification 1 of the embodiment, the first engaging portion EG11 is located above the placement surface PMM and extends in a direction parallel to the pull-out direction. Also, in Modification 1 of the embodiment, 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 first guiding portion GD1 in the second state. In Modification 1 of the embodiment, the engaging portion EG1 has, in addition to the first engaging portion EG11 and the second engaging portion EG12, a third engaging portion EG13 that engages with the first engaged portion EG21 when the second engaging portion EG12 and the second engaged portion EG22 are engaged. The third engagement portion EG13 is located below the second engagement portion and downstream of the second engagement portion EG12 in the conveying direction. More specifically, the third engagement portion EG13 is a recess formed downward from the first engagement portion EG11. Therefore, when the third engagement portion EG13 and the first engaged portion EG21 engage with each other, the first guiding portion GD1 does not slide out in the conveying direction due to gravity because the first engaged portion EG21 is caught on the third engagement portion EG13.

[0048] FIG. 9 is a diagram illustrating the first guide portion GD1 when the first engaged portion EG21 and the third engaging portion EG13 are engaged. In the example illustrated in FIG. 9, the first engaged portion EG21 is engaged with the third engaging portion EG13. Also, in this example, the second engaged portion EG22 is engaged with the second engaging portion EG12. As a result, the upper surface of the first guide portion GD1 is inclined similarly to the upper surface of the first guide portion GD1 illustrated in FIG. 5. Even in this case, the height of the downstream end of the first guide portion GD1 in the second state can be set to a height above the upstream end of the receiver PM or the same height as the upstream end of the receiver PM. In the example illustrated in FIG. 9, the height of the downstream end of the first guide portion GD1 in the second state is set to a height above the upstream end of the receiver PM. Therefore, even in the first modification of the embodiment, the image reading device 1 can suppress deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM.

[0049] In the embodiment and the first modified example of the embodiment, the user can set the first guide portion GD1 to the second state simply by pulling it substantially in the pull-out direction. Therefore, in the first modified example of the embodiment, even if there is no free space above the image reading device 1, the first guide portion GD1 can be displaced from the first state to the second state. Furthermore, in the first modified example of the embodiment, the difference in height between the first engagement portion EG11 and the second engagement portion EG12 and the third engagement portion EG13 can be reduced, so that the vertical length of the image reading device 1 can be shortened, and as a result, the image reading device 1 can be made more compact.

[0050] <Modification 2 of the embodiment> A second modification of the embodiment will be described below. In the second modification of the embodiment, a second guide section GD2 is provided at the downstream end of the first guide section GD1 to guide the medium CP1 guided by the first guide section GD1 in the second state toward a position downstream in the transport direction above the receiver PM from the downstream end of the first guide section GD1. Fig. 10 is a diagram showing yet another example of the configuration of the first guide section GD1. Fig. 11 is an enlarged view of the first guide section GD1 shown in Fig. 10.

[0051] The first guide portion GD1 shown in Figures 10 and 11 has a protrusion TH1, similar to the first guide portion GD1 shown in Figure 6. Here, when the first guide portion GD1 is in the second state, the uppermost end of the protrusion TH1 is at a height higher than the uppermost end of the second guide portion GD2 or at the same height as the uppermost end of the second guide portion GD2. In the example shown in Figures 10 and 11, when the first guide portion GD1 is in the second state, the uppermost end of the protrusion TH1 is at a height higher than the uppermost end of the second guide portion GD2.

[0052] 10 and 11, the first guide portion GD1 is located downstream of the protrusion TH1 in the transport direction and includes a third guide portion GD3 extending in the same direction as the first guide portion GD1. The downstream end of the third guide portion GD3 is located at a height higher than the upstream end of the receiver PM or at the same height as the upstream end of the receiver PM. In the example shown in FIGS. 10 and 11, the downstream end of the third guide portion GD3 is located at the same height as the upstream end of the receiver PM. Because the first guide portion GD1 includes the protrusion TH1 and the third guide portion GD3, the image reading device 1 can prevent contact between the upstream end of the receiver PM and the medium CP1, even if the leading edge of the medium CP1 guided by the protrusion TH1 falls between the receiver PM and the protrusion TH1 for some reason. As a result, the image reading device 1 can more reliably prevent deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM.

[0053] 10 and 11, a second guide section GD2 is provided at the downstream end of the first guide section GD1. The second guide section GD2 guides the medium CP1, guided by the first guide section GD1 in the second state, toward a downstream position in the transport direction from the downstream end of the first guide section GD1 above the receiver PM. More specifically, the second guide section GD2 is a substantially flat-plate-shaped member extending parallel to the upper surface of the third guide section GD3 toward the downstream side in the transport direction. Therefore, when the first guide section GD1 is in the second state, the second guide section GD2 covers the upstream end of the receiver PM. In other words, when the first guide section GD1 is in the second state, at least a portion of the second guide section GD2 is located on the receiver surface PMM. This allows the image reading device 1 to prevent contact between the upstream end of the receiver PM and the medium CP1. As a result, the image reading device 1 can more reliably prevent deformation of the medium CP1 due to contact between the medium CP1 and the placement surface PMM. This is useful because it prevents problems such as poor transport of the medium CP1 by the image reading device 1 and errors in reading images from the medium CP1 by the image reading device 1. Furthermore, because at least a portion of the second guide unit GD2 covers the upper end of the placement unit PM, the image reading device 1 can improve the design freedom for the shape of the upper end of the placement unit PM. This is because, regardless of the shape of the upper end of the placement unit PM below the second guide unit GD2, the leading edge of the medium CP1 guided by the first guide unit GD1 in the second state does not come into contact with the upper end of the placement unit PM.

[0054] 12 is a diagram showing another example of the first guide portion GD1 in the first state. As shown in FIG. 12, when the first guide portion GD1 is in the first state, at least a portion of the second guide portion GD2 is located on the upper surface of the housing BX. Therefore, in this case, the height of the upper surface of the second guide portion GD2 is higher than the height of the upper surface of the first guide portion GD1. This allows the image reading device 1 to prevent dust and the like from accumulating on the placement surface PMM when the first guide portion GD1 is in the first state.

[0055] As described above, the image reading device 1 can suppress deformation of the medium CP1 due to contact between the medium CP1 and the placement surface PMM by providing the first guide portion GD1 with the second guide portion GD2.

[0056] <Modification 3 of the embodiment> The following describes a third modification of the embodiment. In the third modification of the embodiment, instead of the first guide part GD1 being configured to be displaced between the first state and the second state by sliding relative to the casing BX, the first guide part GD1 is configured to be displaced between the first state and the second state by rotating relative to the casing BX. Fig. 13 is a diagram showing yet another example of the configuration of the first guide part GD1.

[0057] The first guide unit GD1 is mounted on the housing BX and is rotatable about a predetermined rotation axis AX relative to the placement surface PMM. The rotation about the rotation axis AX causes the first guide unit GD1 to move between a first state and a second state. The rotation axis AX intersects with the conveyance direction. In the example shown in FIG. 13, the rotation axis AX is perpendicular to the conveyance direction and is therefore parallel to the Y-axis. A user can manually pull the first guide unit GD1 from the first state upward and toward the user, thereby rotating the first guide unit GD1 relative to the placement surface BX and thereby moving the first guide unit GD1 from the first state to the second state. This prevents dust, dirt, and the like that accumulates on the top surface of the first guide unit GD1 from falling onto the placement surface PMM while the image reading device 1 is not in use.

[0058] The first guide unit GD1 also has one or more second protrusions TH2 that protrude upward from the rotation axis AX. In the example shown in FIG. 13, the first guide unit GD1 has three second protrusions TH2. Each of these three second protrusions TH2 guides the medium CP1 guided by the first guide unit GD1 in the second state above the receiver PM, toward downstream in the transport direction from the downstream end of the first guide unit GD1. This allows the image reading device 1 to guide the medium CP1 transported by the transport unit R1 to a height above the upstream end of the receiver unit PM or to the same height as the upstream end of the receiver unit PM, regardless of the position of the rotation axis AX. As a result, the image reading device 1 can more reliably suppress deformation of the medium CP1 due to contact between the medium CP1 and the receiver surface PMM.

[0059] As described above, even if the image reading device 1 is configured so that the first guide part GD1 rotates relative to the housing BX to move between the first state and the second state, deformation of the medium CP1 due to contact between the medium CP1 and the loading surface PMM can be suppressed.

[0060] <Fourth Modification of the Embodiment> A fourth modification of the embodiment will be described below. In the fourth modification of the embodiment, the discharge tray ET1 of the image reading device 1 is positioned above the placement surface PMM. Fig. 14 is a side cross-sectional view showing another example of the configuration of the image reading device 1 attached to the printing device 2. Fig. 14 shows a side cross-sectional view of the image reading device 1 as well as a side cross-sectional view showing an example of the configuration of the printing device 2.

[0061] The dotted line PT2 in FIG. 14 indicates a portion of the path along which the medium CP1 transported by the transport unit R1 passes. The transport unit R1 transports the medium CP1, which is supported by the first guide unit GD1 and the placement surface PMM in the second state below the discharge tray ET1, along the dotted line PT2. The image reading unit SC reads the image from the medium CP1 transported by the transport unit R1 in this manner. After the image has been read by the image reading unit SC, the medium CP1 is discharged to the discharge tray ET1 located above the placement surface PMM. In this case, the entire first guide unit GD1 is located above the placement surface PMM in both the first and second states. This allows the image reading device 1 to more reliably suppress deformation of the medium CP1 due to contact between the medium CP1 and the placement surface PMM. Furthermore, in this case, when the image reading device 1 is viewed from the direction of gravity, the medium CP1 on the discharge tray ET1 is easy to see, making it easier for the user to visually determine whether the reading of the image from the medium CP1 has been completed.

[0062] Here, when the discharge tray ET1 is positioned above the placement surface PMM, the discharge tray ET1 may have a canopy-like structure as shown in Fig. 15. Fig. 15 is a diagram showing an example of the configuration of the discharge tray ET1 in Modification 4 of the embodiment. In Fig. 15, the state of the first guide portion GD1 is the second state. Also, Fig. 16 is an enlarged view of the discharge tray ET1 in Modification 4 of the embodiment.

[0063] 15 and 16, the discharge tray ET1 has a first medium support member ET11 and a second medium support member ET12 that is separate from the first medium support member ET11. The first medium support member ET11 and the second medium support member ET12 are spaced apart so that the distance between them in the intersecting direction is a predetermined distance. In this example, the intersecting direction is a direction perpendicular to the transport direction, i.e., a direction parallel to the Y-axis. The predetermined distance is, for example, about 10 centimeters, but is not limited to this.

[0064] The first medium support part ET11 has an eleventh part E11 that extends upward from the end of the placing surface PMM that is on the negative side of the Y axis, and a flat twelfth part E12 that extends from the eleventh part E11 in the positive direction of the Y axis at a position a predetermined height higher than the placing surface PMM. Therefore, the first medium support part ET11 is a canopy-shaped member that covers part of the placing surface PMM when the image reading device 1 is viewed in the direction of gravity, and has a gap between the twelfth part E12 and the placing surface PMM.

[0065] On the other hand, the second medium support part ET12 has a 21st part E21 that extends upward from the end of the placing surface PMM that is on the positive side of the Y axis, and a flat 22nd part E22 that extends from the 21st part E21 in the negative direction of the Y axis at a position a predetermined height higher than the placing surface PMM. Therefore, the second medium support part ET12 is a canopy-shaped member that covers part of the placing surface PMM when the image reading device 1 is viewed in the direction of gravity, and has a gap between the 22nd part E22 and the placing surface PMM.

[0066] In this way, when the discharge tray ET1 has the first medium support member ET11 and the second medium support member ET12, the upper surface of the discharge tray ET1 is made up of the upper surface of the twelfth portion E12 and the upper surface of the 22nd portion E22. Therefore, the image reading device 1 discharges the medium CP1, whose image has been read by the image reading unit SC, onto the upper surface of the discharge tray ET1, which is made up of the upper surface of the twelfth portion E12 and the upper surface of the 22nd portion E22. In this case, the user can insert their finger through at least one of the gap between the placement surface PMM and the twelfth portion E12 and the gap between the placement surface PMM and the 22nd portion E22 to lift the medium CP1, thereby improving the usability of the image reading device 1.

[0067] Here, when the discharge tray ET1 has a first medium support member ET11 and a second medium support member ET12, the engagement member EG1 of the housing BX is located above the first medium support member ET11 and the second medium support member ET12, as shown in Figures 15 and 16. This is because the first guide member GD1 in the first state is located above the discharge tray ET1. This allows the image reading device 1 to prevent the placement surface PMM, the discharge tray ET1, etc. from being deformed by fallen objects, etc., while the image reading device 1 is not in use.

[0068] In the image reading device 1 described above, when the first guide GD1 is in the first state, the top surface of the first guide GD1 may be configured to be included in a virtual plane that includes the top surface of the housing BX. In this case, when the space above the image reading device 1 is small and narrow, the image reading device 1 can prevent the user from hitting their finger on a step between the first guide GD1 and the housing BX when operating the first guide GD1. Furthermore, in this case, the image reading device 1 does not have such a step. Therefore, the image reading device 1 can prevent the step from detracting from the aesthetic appearance of the device.

[0069] Furthermore, the items described above may be combined in any manner.
