[0031] Here, "the front side of the base unit" refers to the front side of the image reading device. Furthermore, "established" in "established when the opening and closing unit is closed relative to the base unit, a conveying path for conveying the medium in a conveying direction" means that when the opening and closing unit is closed relative to the base unit, the conveying path is in a state where the medium can be conveyed.

[0032] According to this embodiment, the display panel is arranged on the front side of the base unit, and is arranged to overlap with the opening and closing unit in the closed state in the width direction of the conveying path when viewed from the front. Thus, by increasing the size of the display panel in the overlapping direction in the width direction, even when the display panel is enlarged in the width direction for mounting, the enlargement of the image reading device in the width direction can be suppressed.

[0033] The second mode of the image reading device involved in the present invention is a mode subordinate to the first mode, and is characterized in that it comprises: a feeding section that feeds the medium placed on the medium setting section along the conveying direction; and a discharge section that discharges the medium conveyed in the conveying path and passing through the reading section to a discharge receiving section, wherein the discharge receiving section is provided in the opening and closing unit.

[0034] According to this aspect, in the image reading device having the delivery section, the discharge section, and the discharge receiving section, wherein the discharge receiving section is provided in the opening and closing unit, the same effects as those of the first aspect can be obtained.

[0035] A third aspect of the image reading device according to the present invention is an aspect subordinate to the first aspect, and is characterized in that the display panel overlaps the opening and closing unit in the closed state in the height direction when viewed from the front. In addition, this aspect can also be subordinate to the second aspect.

[0036] According to this embodiment, the display panel overlaps the opening and closing unit in the closed state in the height direction when viewed from the front. That is, by setting the display panel to a size that does not exceed the area in the height direction of the opening and closing unit when viewed from the front, it is possible to suppress enlargement in the height direction in addition to the width direction.

[0037] A fourth aspect of the image reading device according to the present invention is an aspect dependent on the third aspect, and is characterized in that the opening and closing unit has a recessed portion formed in a portion overlapping with the display panel, and the display panel can be accommodated in the recessed portion.

[0038] According to this embodiment, the opening and closing unit is provided with a recessed portion at a portion overlapping with the display panel, and the display panel can be accommodated in the recessed portion. Thus, in addition to the width and height directions, the image reading device can also be prevented from being enlarged in the depth direction.

[0039] The fifth mode of the image reading device of the present invention is a mode subordinate to the first mode, characterized in that the height position of the display panel when the opening and closing unit is in the open state is the same as the height position of the display panel when the opening and closing unit is in the closed state. In addition, this mode can also be subordinate to any one of the second to fourth modes.

[0040] According to this embodiment, the height position of the display panel when the opening and closing unit is in the open state is the same as the height position of the display panel when the opening and closing unit is in the closed state. That is, the height position of the display panel does not change due to the opening and closing state of the opening and closing unit, so it is easy to confirm the display information on the display panel.

[0041] The sixth mode of the image reading device of the present invention is a mode subordinate to the first mode, characterized in that the medium setting portion can rotate with the base end as a rotation fulcrum, and can be displaced to an expanded state and a stored state by rotating, and in the stored state of the medium setting portion, the display panel is covered by the medium setting portion. In addition, this mode can also be subordinate to any one of the second mode to the fifth mode.

[0042] According to this embodiment, the medium setting portion can be displaced to an expanded state and a stored state by rotating with the base end as a rotation fulcrum, and in the stored state of the medium setting portion, the display panel is covered by the medium setting portion. Thus, the display panel can be protected when the image reading device is not in use.

[0043] When this aspect is subordinate to the third aspect, the gap in the depth direction when the medium setting portion is in the stored state is reduced.

[0044] A seventh aspect of the image reading device according to the present invention is an aspect dependent on the sixth aspect, and is characterized in that at least a part of a region of the medium setting portion that covers the display panel is a light-transmitting member.

[0045] According to this aspect, at least a portion of the area of ​​the medium setting portion covering the display panel is a light-transmitting member. Thus, even when the display panel is covered by the medium setting portion, information displayed on the display panel can be confirmed, which improves user convenience.

[0046] An eighth aspect of the image reading device according to the present invention is an aspect dependent on the first aspect, and is characterized in that the display panel can change the position of the free end from a default position by rotating with the base end as a rotation fulcrum.

[0047] According to this embodiment, the display panel is rotated with the base end as a rotation fulcrum, so that the position of the free end can be changed from the default position. As a result, the display panel can be easily changed to a direction that is easy for the user to observe. In addition, when the display panel becomes an obstacle during maintenance work such as cleaning of the base unit or replacement of parts, the maintenance work can be easily performed by performing the rotation.

[0048] The ninth mode of the image reading device involved in the present invention is a mode subordinate to the eighth mode, and is characterized in that the medium setting portion can rotate with the base end as a rotation fulcrum, and can be displaced into an expanded state and a stored state by rotating, and when the position of the free end of the display panel is changed from the default position, if the medium setting portion is changed from the expanded state to the stored state, the display panel is pressed to return the display panel to the default position.

[0049] According to this aspect, when the position of the free end of the display panel is changed from the default position, if the medium setting portion is changed from the expanded state to the stored state, the display panel is pressed to return the position of the free end to the default position. This improves user convenience.

[0050] The tenth mode of the image reading device involved in the present invention is a mode subordinate to the ninth mode, and is characterized in that it comprises: a driving mechanism that moves the medium setting part in the storage state upward; and a first imparting mechanism, the medium setting part is moved upward by the driving mechanism, so that the first imparting mechanism imparts a force to the medium setting part to change the medium setting part from the position of the storage state to the position of the expanded state.

[0051] According to this mode, the medium setting part is moved upward by the driving mechanism, so that the first imparting mechanism imparts a force to the medium setting part to change the medium setting part from the position of the storage state to the position of the unfolded state. Thus, for example, when the driving mechanism is driven by power being turned on, the medium setting part starts to move upward, and then the first imparting mechanism acts on the medium setting part to automatically change the medium setting part from the position of the storage state to the position of the unfolded state, which is convenient for users.

[0052] The eleventh aspect of the image reading device of the present invention is an aspect subordinate to the first aspect, characterized in that the medium setting portion can rotate with the base end as a rotation fulcrum, and can be displaced to an unfolded state and a stored state by rotating, and the medium setting portion further has a cutout portion, and when the medium setting portion is in the stored state, the display panel is stored in the cutout portion. In addition, this aspect can also be subordinate to any one of the second to fifth and eighth aspects.

[0053] According to this embodiment, the medium setting portion can be displaced to the unfolded state and the stored state by rotating, and further comprises a cutout portion, and when the medium setting portion is in the stored state, the display panel is stored in the cutout portion. Thus, even when the medium setting portion is in the stored state, the information displayed on the display panel can be confirmed, and the user's convenience is good.

[0054] The twelfth mode of the image reading device involved in the present invention is a mode subordinate to the eleventh mode, and is characterized in that the display panel is rotated with the base end as a rotation fulcrum so that the position of the free end can be changed from a default position, and the image reading device comprises: a driving mechanism, which moves the medium setting part in the storage state upward; a second imparting mechanism, the medium setting part is moved upward by the driving mechanism, so that the second imparting mechanism imparts a force to the display panel to change the display panel from the default position; and a first imparting mechanism, the medium setting part is moved further upward by the driving mechanism, so that the first imparting mechanism imparts a force to the medium setting part to change the medium setting part from the position of the storage state to the position of the expanded state.

[0055] According to this embodiment, when the medium setting portion is moved upward by the driving mechanism, the second imparting mechanism imparts a force to the display panel to change the display panel from the default position. Next, the first imparting mechanism imparts a force to the medium setting portion to change the medium setting portion from the position of the stored state to the position of the expanded state. Thus, for example, if the driving mechanism is driven by power being turned on, the medium setting portion starts to move upward, the second imparting mechanism acts on the display panel to rotate the display panel, and then the first imparting mechanism acts on the medium setting portion to automatically change the medium setting portion from the position of the stored state to the position of the expanded state. That is, the display panel can be changed from the default position to the use position, and the medium setting portion can be changed to the expanded state continuously and automatically, which is convenient for users.

[0061] like Figure 1 As shown, the image reading device 1 of this embodiment includes a first reading unit 51 and a second reading unit 52 as two reading units for reading an image of a medium 3. The image reading device 1 further includes: a first conveying roller 4 that conveys the medium 3 in a conveying direction F along a conveying path 2 and is disposed upstream of the first reading unit 51 in the conveying direction F; a second conveying roller 6 that is disposed upstream of the second reading unit 52 that is located downstream of the first reading unit 51; and a third conveying roller 8 that is disposed downstream of the second reading unit 52.

[0062] A roller pair of a feed roller 10 and a separation roller 7 is arranged upstream of the first feed roller 4 in the feed direction F. The feed roller 10 is a drive roller that rotates by the power of the third drive unit 15 and feeds the medium 3 in the feed direction F. The separation roller 7 is a drive roller that rotates by the power of a driving source (not shown) and is a roller that separates one medium from a plurality of mediums 3.

[0063] Here, the separation roller 7 rotates in a direction to send the medium 3 to the upstream side (+Y direction) of the conveying direction F by the power of the driving source. The separation roller 7 is provided with a torque limiter (not shown), and when a torque exceeding a set value is applied to the torque limiter, the separation roller 7 is driven to rotate in a direction to send the medium 3 to the downstream side (-Y direction) of the conveying direction F.

[0064] A pickup roller 12 (using the same reference numeral) as the delivery unit 12 is disposed upstream of the separation roller 7. The pickup roller 12 is a drive roller that rotates by the power of the third drive unit 15 similarly to the feed roller 10, and delivers the medium 3 in the conveying direction F. The first conveying roller 4, the second conveying roller 6, and the third conveying roller 8 constitute the conveying unit 5 that conveys the medium 3 in the conveying direction F, and each of them includes a drive roller that rotates by the power of the third drive unit 15.

[0065] like Figure 1 As shown, in this embodiment, a curved reversing path 18 is provided downstream of the straight path 68 from the feed roller 10 to the third conveying roller 8, that is, downstream of the third conveying roller 8. The fourth conveying roller 20, the fifth conveying roller 22, and the discharge roller pair 24 as the discharge unit 24 (using the same reference numerals) are arranged in this order along the conveying direction F on the curved reversing path 18.

[0066] The discharge receiving portion 16 that receives the medium 3 discharged from the curved inverting path 18 is disposed above the straight path 68 to achieve compactness.

[0067] exist Figure 1 In the figure, reference numeral 71 denotes a control unit. The control unit 71 controls the driving of the third driving unit 15 and the driving of the fourth driving unit 27 described later according to the conveyance of the medium 3. The third driving unit 15 and the fourth driving unit 27 are constituted by motors.

[0068] The control unit 71 includes a CPU, a flash ROM, and a RAM. The CPU performs various calculations according to the program stored in the flash ROM to control the overall operation of the image reading device 1. The flash ROM, as an example of a storage unit, is a non-volatile memory that can be read and written. Various information is temporarily stored in the RAM, as an example of a storage unit.

[0069] exist Figure 1 In the figure, reference numeral 14 denotes a medium setting portion for setting a medium 3 to be read. The medium 3 on the medium setting portion 14 is conveyed in the conveyance path 2 and finally discharged to the discharge receiving portion 16.

[0070] The medium setting part 14 is configured to move up and down. When the medium 3 set in the medium setting part 14 is conveyed in the conveying direction F, the medium setting part 14 is firstly transmitted with power from a driving source (not shown) and moves upward (in the +Z direction), and stops when the uppermost medium 3 among the set media 3 contacts the pickup roller 12. In this state, the pickup roller 12 rotates, thereby conveying the medium 3 in the conveying direction F, and the front end of the medium 3 reaches the roller gap position of the roller pair of the feed roller 10 and the separation roller 7.

[0071] When the medium 3 is in a multi-feed state where multiple sheets are fed, one sheet is separated by the separation roller 7, and this sheet is conveyed along the conveying direction F by the first conveying roller 4, and the image of the first side of the medium 3 is read by the first reading unit 51. Furthermore, the medium 3 that has been read by the first reading unit 51 is conveyed by the second conveying roller 6, and the image of the second side of the medium 3 opposite to the first side is read by the second reading unit 52.

[0072] The medium 3 scanned by the second scanning unit 52 is sent to the curved reversing path 18 by the third conveying roller 8 , conveyed by the fourth conveying roller 20 and the fifth conveying roller 22 , and discharged to the discharge receiving unit 16 by the discharge roller pair 24 .

[0073] like Figure 1 As shown, in this embodiment, the first reading unit 51 and the second reading unit 52 for reading an image of the medium 3 transported in the transport direction F include the light-transmitting member 43 disposed between the transport path 2 , namely, the first light-transmitting member 431 and the second light-transmitting member 432 .

[0074] like Figure 1 As shown in the figure, the first rotating member 131 and the second rotating member 32 as rotating members are arranged on the side of the first light-transmitting member 431 and the second light-transmitting member 432 opposite to the first reading section 51 and the second reading section 52. The first rotating member 131 and the second rotating member 32 are rotating members arranged opposite to the first reading section 51 and the second reading section 52 and rotatable around the shaft 11. The first rotating member 131 and the second rotating member 32 are substantially cylindrical in shape and are formed to have a length that can cover the reading range (X-axis direction) of the first reading section 51 and the second reading section 52.

[0075] And, if Figure 1 As shown, the first rotating member 131 and the second rotating member 32 rotate around the shaft 11 by the power of the fourth driving unit 27 as a common driving source. The rotation of the first rotating member 131 and the second rotating member 32 is controlled by the control unit 71.

[0076] In addition, the first rotating member 131 and the second rotating member 32 may be configured to rotate by the power of their respective motors instead of by the common fourth driving unit 27 .

[0077] The first reading unit 51, the first light-transmitting member 431, and the second rotating member 32 are arranged above the conveying path 2. The second reading unit 52, the second light-transmitting member 432, and the first rotating member 131 are arranged below the conveying path 2.

[0078] like Figure 1As shown, in this embodiment, the image reading device 1 includes a base unit 55 and an opening and closing unit 56. The opening and closing unit 56 is configured to be able to be opened and closed by rotating in the vertical direction relative to the base unit 55 by an opening and closing mechanism (not shown).

[0079] The base unit 55 has a second reading unit 52, a second light-transmitting member 432, and a first rotating member 131. The opening and closing unit 56 has a first reading unit 51, a first light-transmitting member 431, and a second rotating member 32. When the opening and closing unit 56 is closed relative to the base unit 55, Figure 1 In the configuration shown, the second light-transmitting member 432 is opposite to the second rotating member 32 , and the first light-transmitting member 431 is opposite to the first rotating member 131 .

[0080] When the opening and closing unit 56 is opened relative to the base unit 55, which is not shown in the figure, the second light-transmitting member 432 is not opposite to the second rotating member 32, and the first light-transmitting member 431 is not opposite to the first rotating member 131. That is, the opposing surfaces of the base unit 55 and the opening and closing unit 56 are exposed and accessible to the user.

[0081] And, if Figure 1 As shown, in this embodiment, a first conveyance assisting portion 61 and a second conveyance assisting portion 62 are provided as conveyance assisting portions, and the first conveyance assisting portion 61 and the second conveyance assisting portion 62 are opposed to the first light-transmitting member 431 and the second light-transmitting member 432, and are arranged upstream of the first rotating member 131 and the second rotating member 32 to assist the conveyance of the medium 3. Here, the first conveyance assisting portion 61 and the second conveyance assisting portion 62 are composed of a driving roller 26 called a pressure roller 26, and the pressure roller 26 is rotated by the power transmitted from the third driving portion 15.

[0082] Implementation Method 1

[0083] Following the above description of the overall structure of the image reading device 1 , a first embodiment of the image reading device 1 will be described below, with some parts being repeated.

[0084] like Figure 1 to Figure 7 As shown, the image reading device 1 of this embodiment includes: a base unit 55; an opening and closing unit 56 that can be opened and closed relative to the base unit 55; a medium setting portion 14 that is arranged on the front side 40 of the base unit 55 and is used to place the medium 3; and a conveying path 2 that is opened when the opening and closing unit 56 is closed relative to the base unit 55 ( Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 ) is established, and the medium 3 is transported along the transport direction F. The base unit 55 includes a right cover 57, a left cover 58, and a rear cover 59 as a housing. Figure 3 In the figure, reference numerals 41 and 42 denote edge guides. Figure 6 and Figure 5 In the figure, reference numeral 65 denotes a hinge. The opening and closing unit 56 can be closed by rotating with the hinge 65 as a rotation fulcrum. Figure 5 The state and open state are Figure 6 state switching.

[0085] Here, the front side 40 of the base unit 55 refers to the front side 40 of the image reading device 1 (the same reference numerals are given). Furthermore, the “established” in the conveying path 2 that is established in the state where the opening and closing unit 56 is closed relative to the base unit 55 and conveys the medium 3 in the conveying direction F refers to a state where the medium 3 can be conveyed as the conveying path 2 in the state where the opening and closing unit 56 is closed relative to the base unit 55.

[0086] In addition, in this embodiment, a first reading unit 51 and a second reading unit 52 ( Figure 1 ), arranged along the conveying path 2, for reading an image of the medium 3; and a display panel 19 ( Figures 3 to 6 ), which displays the information required when using the image reading device 1.

[0087] The display panel 19 is disposed on the front side 40 of the base unit 55 and is disposed so as to overlap the closed opening and closing unit 56 in the width direction (X-axis direction) of the conveyance path 2 when viewed from the front. Reference numeral 17 denotes a screen of the display panel 19 .

[0088] like Figure 7 As shown, in this embodiment, the display panel 19 is configured to rotate with the base end 28 as a rotation fulcrum, so that the position of the free end 29 can be changed from the default position ( Figure 3 ) change. The default position refers to a state in which the display panel faces the +Y direction and is located along the Z axis, and the free end is located in the -Z direction relative to the base end. Here, the display panel 19 is configured so that the base end 28 is above the free end 29 and rotates in the up and down direction. Specifically, the display panel 19 is installed on the inner surface of the right cover 57 through a hinge (not shown) so that the free end 29 rotates with the base end 28 as a rotation fulcrum and can change the direction of the screen 17. In this embodiment, the display panel 19 is rotated manually.

[0089] Here, the display panel 19 is arranged so that a portion of the right side (+X side) also overlaps with a portion of the front side 40 of the right cover 57. Furthermore, the display panel 19 is arranged so as not to protrude from the right cover 57 to the right side (+X side).

[0090] In other words, the display panel 19 is not mounted on the side of the opening and closing unit 56 that is displaced by the opening and closing action, but is mounted on the side of the base unit 55 that does not displace. Even when the opening and closing unit 56 is displaced by the opening and closing action, the display panel 19 does not displace.
