DETAILED DESCRIPTION OF THE INVENTION

[0008] The present invention will now be briefly described. In order to solve the above problem, an image reading device according to a first aspect of the present invention comprises a scanner unit that reads a document, an ADF unit that is provided above the scanner unit and that transports and can read the document, a first board that controls the operation of the scanner unit, and a second board that controls the operation of the ADF unit, and is characterized in that the first board and the second board are provided in a board placement section of the ADF unit.

[0009] According to this aspect, the first board and the second board are provided in a board placement section of the ADF unit. As a result, the first board for the scanner unit and the second board for the ADF unit are both provided within the ADF unit, eliminating the need to ensure installation space for placing each control board in the scanner unit and the ADF unit, and preventing the device from becoming larger. Furthermore, when it becomes necessary to replace either or both of the first and second substrates, the replacement work only needs to be performed on the ADF unit, making the work easier.

[0010] The image reading device according to a second aspect of the present invention is the image reading device of the first aspect, characterized in that the first substrate is arranged to extend in a direction intersecting the horizontal direction.

[0011] According to this aspect, by placing the first substrate in a direction intersecting the horizontal direction, for example, vertically, it is possible to reduce the size in the horizontal direction, that is, the size in the front-rear or left-right direction.

[0012] An image reading device according to a third aspect of the present invention is the image reading device according to the first or second aspect, characterized in that the second substrate is arranged to extend in a direction intersecting the horizontal direction.

[0013] According to this aspect, by placing the second substrate in a direction intersecting the horizontal direction, for example, vertically, it is possible to reduce the size in the horizontal direction, that is, the size in the front-rear or left-right direction.

[0014] An image reading device according to a fourth aspect of the present invention is characterized in that, in the first aspect, the first substrate and the second substrate are arranged to extend in a first direction that intersects the horizontal direction, and overlap when viewed in the horizontal direction.

[0015] According to this aspect, by placing both the first and second substrates in a direction that intersects the horizontal direction, for example, vertically, it is possible to more effectively prevent the size of the device in the horizontal direction, for example, the front-to-back direction, from increasing. Furthermore, by overlapping the first and second substrates when viewed in the horizontal direction, the size of the device in the horizontal direction, for example, the left-right direction, can be reduced.

[0016] The image reading device according to a fifth aspect of the present invention is the image reading device of the fourth aspect, characterized in that the first board is disposed on the outer side of the second board.

[0017] According to this aspect, when only the first board is removed for maintenance or the like, there is no need to disconnect the second board or the wiring connected to the second board, which simplifies the work.

[0018] An image reading device according to a sixth aspect of the present invention is characterized in that, in the fourth or fifth aspect, it has wiring connecting the first substrate and the second substrate, and the area of ​​the first substrate and the second substrate that do not overlap when viewed horizontally overlaps with the wiring when viewed horizontally. Here, "the non-overlapping areas between the first substrate and the second substrate when viewed horizontally overlap with the wiring when viewed horizontally" means that the wiring connecting the first substrate and the second substrate is arranged through the non-overlapping areas.

[0019] According to this aspect, the area where the first and second substrates do not overlap in the horizontal direction can be used as a wiring installation space, thereby preventing the wiring from protruding and increasing the device size. Furthermore, by passing the wiring through the non-overlapping area, the length of the wiring can be shortened. Furthermore, by consolidating the wiring around the area where the circuit board is placed at the rear of the device, the wiring can be made shorter and simpler. In addition, the wiring work can be done in one place, making the work easier.

[0020] An image reading device according to a seventh aspect of the present invention is characterized in that, in any one of the fourth to sixth aspects, it has wiring connected to the first substrate or the second substrate, and the wiring is included in an area of ​​the substrate in the first direction.

[0021] According to this aspect, the wiring connected to the first substrate or the second substrate is included in the region of the substrate in the first direction, so that the wiring does not protrude upward or downward relative to the substrate, thereby reducing the height dimension of the device.

[0022] An image reading device according to an eighth aspect of the present invention is characterized in that, in any one of the first to seventh aspects, it has a first holding portion and a second holding portion that hold the ADF unit rotatably relative to the scanner unit, and the board placement portion is provided between the first holding portion and the second holding portion. Here, "between the first holding portion and the second holding portion" in "the substrate placement portion is provided between the first holding portion and the second holding portion" does not mean that the substrate placement portion does not have to be completely contained therebetween, but rather that it may be arranged, for example, between the outer ends of the first holding portion and the second holding portion in the left-right direction.

[0023] According to this aspect, the first and second substrates provided in the substrate placement section are provided between the first holding section and the second holding section, thereby making it possible to reduce the size in the left-right direction.

[0024] An image reading device according to a ninth aspect of the present invention is characterized in that, in any one of the first to seventh aspects, it has a holding section that holds the ADF unit rotatably relative to the scanner unit, the ADF unit includes a transport section that transports the document and a drive section that drives the transport section, and the board placement section is provided between the holding section and the drive section. Here, "between the holding part and the driving part" in "the substrate placement part is provided between the holding part and the driving part" does not mean that it does not have to be completely contained therebetween, but rather that it may be arranged between the outer ends of the holding part and the driving part in the left-right and front-back directions, for example.

[0025] According to this aspect, the first and second substrates provided in the substrate placement section are provided between the holding section and the drive section, so that the size in the left-right and front-rear directions can be reduced.

[0026] In addition, in any one of the first to ninth aspects, the scanner unit may be provided with a cable that sends data obtained by reading the original to the first board, and the board placement section may be arranged so as to overlap the cable when viewed horizontally.

[0027] With this arrangement, the cable such as FFC used to receive the data read from the second surface and the board placement section overlap, so it is possible to prevent the device from becoming larger due to the cable. Furthermore, by consolidating the cables and wiring at the rear of the device, the length of the cables and wiring can be shortened, resulting in a simple structure. In addition, wiring work can be done in one place, making the work easier.

[0028] An image reading device according to a tenth aspect of the present invention is characterized in that, in any one of the first to ninth aspects, at least one of the first board and the second board is detachably attached to the board placement section by an attachment member, and the attachment member is inserted and removed along a first direction that intersects with the horizontal direction.

[0029] According to this aspect, by making the mounting direction via the mounting member of at least one of the first and second substrates the same as the insertion / removal direction of the mounting member, the work of attachment and detachment becomes easier to perform and it becomes easier to secure working space.

[0030] A recording device according to an eleventh aspect of the present invention is characterized by comprising an image reading device according to any one of the first to tenth aspects, and a recording unit capable of performing recording based on data read by the image reading device.

[0031] According to this aspect, it is possible to prevent an increase in size of a recording device that records the results of reading by the image reading device on a medium.

[0032] A recording device according to a twelfth aspect of the present invention is characterized in that, in the eleventh aspect, the recording unit has a main board that controls the entire device, and the main board is connected to the first board or the second board by wiring.

[0033] According to this aspect, the recording unit has a main board that controls the entire device, and the main board is connected to the first board or the second board by wiring, which enables information to be exchanged between the image reading device and the recording unit.

[0034] A thirteenth aspect of the present invention is directed to the recording apparatus of the twelfth aspect, characterized in that the wiring is guided by a guide portion, and the guide portion is provided rotatably with respect to the ADF unit.

[0035] According to this aspect, the wiring is guided by a guide portion, and the guide portion is provided rotatably relative to the ADF unit, thereby enabling the wiring to be guided with a simple configuration and improving the appearance.

[0036] A recording device according to a 14th aspect of the present invention is characterized in that, in the 11th aspect, the recording unit has a main board that controls the entire device, and the main board overlaps with the board placement section when viewed in a first direction that intersects the horizontal direction.

[0037] According to this aspect, the recording unit has a main board that controls the entire device, and the main board overlaps with the board placement section when viewed in a first direction that intersects with the horizontal direction, thereby effectively reducing the size of the device.

[0038] [Embodiment] An image reading device according to an embodiment of the present invention and a recording device including the image reading device will be specifically described below with reference to FIGS. In the following explanation, the three mutually orthogonal axes are referred to as the X-axis, Y-axis, and Z-axis, as shown in each figure. The Z-axis direction corresponds to the vertical direction (the direction in which gravity acts). The X-axis and Y-axis directions correspond to the horizontal direction.

[0039] As shown in FIG. 5, the recording device 100 of this embodiment includes an image reading device 1 and a recording unit 3 that can perform recording based on data read by the image reading device 1. In this embodiment, the recording unit 3 is an inkjet printer that transports a medium (not shown) such as printing paper stored in a media cassette or the like to a recording execution section using a recording head or the like using a transport roller, and performs recording by ejecting ink there, and is able to perform recording based on data read by the image reading device 1.

[0040] As shown in FIG. 5, the image reading device 1 includes a scanner unit 9 that reads the original 5, and an ADF unit 13 that is provided above the scanner unit 9 and is capable of transporting and reading the original 5. 2 and 4, the device further includes a first board 15 that controls the operation of the scanner unit 9 and a second board 17 that controls the operation of the ADF unit 13. The first board 15 and the second board 17 are both provided in a board placement section 19 of the ADF unit 13. The board placement section 19 is located in a rear section 14 of the ADF unit 13 in the front-to-rear direction. 1 and 2, the ADF unit 13 is attached to the scanner unit 9 located below so as to be rotatable by a pair of left and right hinges, i.e., a first holding portion 2 and a second holding portion 4, located at the rear portion 14. In other words, the front portion 16 of the ADF unit 13 is attached as a free end so as to be able to open and close relative to the scanner unit 9. Each component will be described in detail below.

[0041] <Scanner unit> In this embodiment, the scanner unit 9 places the original 5 on a transparent document placing plate (not shown) with the ADF unit 13 in the "open" position relative to the scanner unit 9, and the original 5 is read by a scanner reading section (not shown) such as a line image sensor located below the document placing plate. When reading, the scanner reading section moves along the reading surface of the original 5 in the device width direction (X-axis direction). Incidentally, the state in which the document 5 is placed on the document placement plate and is read by the scanner-side reading unit is not shown in the figure, as this is well known.

[0042] <ADFユニット> As shown in FIGS. 1 and 5, when the ADF unit 13 is in the "closed" state relative to the scanner unit 9, the document 5 set in the feed tray 6 is transported along a transport path by a transport unit. The transport unit is composed of a known pickup roller (not shown) and transport rollers 8 (FIG. 4), etc. The transport path has a U-shaped reversing unit 10, and the document 5 transported along the transport path is discharged onto a discharge tray 12. The discharge tray 12 is located above the document placement plate of the scanner unit 9. When the original 5 is transported through the U-shaped reversing unit 10, the original 5 is read by an ADF reading unit (not shown) such as a line image sensor. The ADF reading unit is arranged to read an image on a second side 11 of the original 5 set on the feed tray 6, which is the side that contacts the feed tray 6. The state in which the document 5 conveyed by the conveying section 8 is read by the ADF reading section is omitted from the illustration, as this is well known.

[0043] In this embodiment, the ADF unit 13 has a removable rear cover 22 provided at its rear portion 14. Removing the rear cover 22 reveals the board placement section 19, which is covered from above with a top cover 24 (FIG. 3) made of a flame-retardant material. The top cover 24 is also removable, and by removing this top cover 24, the board placement section 19 is exposed, allowing for work such as replacing the first board 15 and the second board 17. The state in FIG. 3 is the state in FIG. 1 with the rear cover 22 removed, and the state in FIG. 2 is the state in FIG. 3 with the top cover 24 removed. The top cover 24 is removably attached to the attachment portion of the ADF unit 13 with two screws 30. The rear cover 22 is also removably attached to the attachment portion of the ADF unit 13 with a plurality of screws (not shown).

[0044] <When images are printed on both sides of the document> The image reading device 1 of this embodiment is configured so that when images are formed on both the front and back sides of the document 5, both sides of the image can be read at once. That is, when the document 5 set in the feed tray 6 is transported by the transport mechanism along a transport path having a U-shaped reversing section 10, the document 5 passes between the ADF reading unit and the scanner reading unit. During this passage, the scanner reading unit does not move and is kept stationary. This allows images on both sides of the document 5 to be read at once using the ADF reading unit and the scanner reading unit. Specifically, in Figure 5, the second side 11 of the document 5 set in the feed tray 6 is read by the ADF reading unit, and the first side 7, which is opposite to the second side 11 of the document 5, is read by the scanner reading unit, which is in a stopped state.

[0045] <Board placement section, first board, second board> In this embodiment, as described above, the board placement section 19 is located in the rear section 14 of the ADF unit 13. The first board 15 is arranged to extend in a direction intersecting the horizontal direction. The second board 17 is also arranged to extend in a direction intersecting the horizontal direction. That is, the first board 15 and the second board 17 are both arranged in the board placement section 19 to extend in a first direction intersecting the horizontal direction. 2 and 4, the first substrate 15 and the second substrate 17 are arranged vertically in the substrate arrangement section 19. The first substrate 15 and the second substrate 17 are arranged parallel to each other and overlap when viewed horizontally. Here, the substrate arrangement section 19 is the combined area of ​​a first region 18 occupied by the first substrate 15 arranged therein and a second region 20 occupied by the second substrate 17 arranged therein. The term "vertical" does not necessarily mean vertical in the strict sense, but may be tilted as long as the effects of the present invention are obtained. The term "parallel" does not necessarily mean parallel in the strict sense, but may be deviated from parallel as long as the effects of the present invention are obtained. 2 and 4, in this embodiment, the first board 15 is disposed on the outer side of the second board 17. By placing the first board 15 directly above the wiring outlet 28 of the scanner unit 9, it is possible to prevent the wiring route of the scanner unit 9 from becoming complicated.

[0046] <Wiring> 6 and 7, this embodiment has wiring 21 connecting first substrate 15 and second substrate 17. The non-overlapping region 23 between first substrate 15 and second substrate 17 in the horizontal direction is provided so as to overlap with wiring 21 in the horizontal direction. As can be seen from FIGS. 6 and 7, "non-overlapping region 23 in the horizontal direction" refers to a region that occurs when first substrate 15 and second substrate 17 are arranged to be offset in the width direction (X-axis direction) of the device. This wiring 21 allows signals to be exchanged between the first board 15 and the second board 17. For example, when images on both sides of the document 5 are read at once using the ADF reading unit and the scanner reading unit, the data read by the scanner reading unit is sent from the first board 15 to the second board 7 via the wiring 21. It is also possible to configure the scanner reading unit and the second board 17 to be directly connected by wiring so that the read data is sent directly to the second board 17. Here, "overlapping with wiring 21 when viewed in the horizontal direction" means that wiring 21 connecting first substrate 15 and second substrate 17 is arranged through non-overlapping region 23. The wiring 21 is a wiring that connects the first substrate 15 and the second substrate 17, but is not limited to this. That is, in FIG. 6, the wiring 21 extends so as to intersect with an extension line of the first substrate 15 provided outside the second substrate 17. Therefore, if there is no "area where the first substrate 15 and the second substrate 17 do not overlap when viewed in the horizontal direction," the wiring will have to detour around the outside of the substrate placement area, which could result in the device becoming larger due to the wiring space. In contrast to this, in this embodiment, the wiring 21 extending to intersect with the extension line of the first substrate 15 is arranged to overlap with the "non-overlapping area when viewed in the horizontal direction" between the first substrate 15 and the second substrate 17, thereby preventing the device from becoming larger due to wiring space.

[0047] 6 and 7, in addition to the wiring 21, the first substrate 15 or the second substrate 17 has wiring 25, 27, and 29 connected thereto. The wiring 25, 27, and 29 are connected to various sensors, motors, and other actuators. The wiring 21 and the wiring 25, 27, and 29 are provided so as to be included in the first direction of the first substrate 15 and the second substrate 17, i.e., the region in the "vertical orientation" described above. In other words, the wiring 21 and the wiring 25, 27, and 29 are arranged so as to be routed in the left-right direction (X-axis direction) and the depth direction (Y-axis direction) so as not to protrude in the up-down direction (Z-axis direction) of the first substrate 15 and the second substrate 17. The portions of first substrate 15 and second substrate 17 where wiring 21 and wiring 25, 27, and 29 are connected have connectors that enable wiring 21 and wiring 25, 27, and 29 to be routed in the left-right direction (X-axis direction) and depth direction (Y-axis direction). Furthermore, by removing wiring 21 and wiring 25, 27, and 29 from the connectors, first substrate 15 and second substrate 17 are separated from the respective wirings and become free, and can be easily removed from ADF unit 13. The wire 21 and the wires 25 , 27 , and 29 are collected at the rear of the ADF unit 13 . In the same figure, some of the wiring 25, 27, and 29 are omitted from the illustration in order to avoid complicating the drawing, but these wirings are also arranged so as not to protrude in the vertical direction (Z-axis direction) of the first substrate 15 and the second substrate 7, just like those shown in the figure.

[0048] Here, the wiring 25 indicates wiring that comes out from the first substrate 15 and is connected to a drive mechanism (not shown) of the scanner unit 9. The wiring 25 passes through a wiring outlet 26 and is introduced from inside the ADF unit 13 into the scanner unit 9. The wiring 27 is shown extending from the second substrate 17 and connected to the drive section 31 (FIG. 2) of the ADF unit 13. The second substrate 17 is located immediately to the right of the drive mechanism section 31. The wiring 29 is shown as coming out from the first substrate 15 and connected to the main substrate 35 (FIG. 5) of the recording unit 3. The wiring 29 passes through the wiring outlet 28 and is introduced from inside the ADF unit 13 into the recording unit 3.

[0049] 5, the wiring 29 introduced into the recording unit 3 is connected to a main board 35 that controls the entire device of the recording unit 3. This allows the recording unit 3 to perform recording based on the data read by the image reading device 1. In this embodiment, the main board 35 is arranged so as to overlap the board placement portion 19 when viewed in the first direction, that is, the vertical direction. Specifically, the main board 35 is disposed at the rear in the front-to-rear direction of the recording unit 3. The main board 35 is disposed "vertically" at a position that is approximately the same rear as the first board 15 in the area below the wiring outlet 28. In other words, the surface formed by the main board 35 and the surface formed by the first board 15 are disposed in a state in which they can be regarded as approximately one surface. Here, "a state in which they can be regarded as approximately one surface" means that either one may protrude as long as they overlap.

[0050] <Scanner unit cable> 7, in this embodiment, the scanner unit 9 includes a cable 37 that transmits data obtained by reading the document 5 using a reading section (not shown) to the first board 15. The cable 37 is made of an FFC. The board placement section 19 is arranged so as to overlap the cable 37 when viewed horizontally. This allows the cable 37 to be positioned within the width direction of the board placement section, thereby shortening the required length of the cable 37. Furthermore, since the cable 37 can be connected by pulling it straight up instead of pulling it around to the left and right, the length can be reduced more effectively. The cable 37 is configured so as to be detachable from the connection portion with the first substrate 15. By detaching the cable 37 from the connection portion with the first substrate 15, the first substrate 15 is separated from the cable 37 and becomes free, and can be easily removed from the ADF unit 13.

[0051] 7, in this embodiment, the first substrate 15 and the second substrate 17 are detachably attached to the substrate placement section 19 by attachment members 39 and 41, respectively. The attachment members 39 and 41 are configured so that they can be inserted and removed along a first direction that intersects with the horizontal direction, that is, in the vertical direction. Here, the attachment members 39 and 41 are made of sheet metal shielding plates, and have a shape and structure that allows them to hold the substrates 15 and 17 to be held. Specifically, the attachment member 39 is attached to the attachment portion of the ADF unit 13 with two screws 32, and the attachment member 41 is attached to the attachment portion of the ADF unit 13 with three screws 34. By removing these screws 34 and 36, the attachment members 39 and 41 can be pulled out upward.

[0052] 8, the first substrate 15 is detachably attached to a mounting member 39 with six screws 36. By removing all of the screws 36, the first substrate 15 can be removed from the holding member 39. 9, the second substrate 17 is detachably attached to a mounting member 39 with six screws 38. By removing all of the screws 38, the second substrate 17 can be removed from the holding member 41. Note that FIG. 9 is a view in which the first substrate 15 has been removed from FIG. 8 so that the entire second substrate 17 can be seen.

[0053] 2, as described above, the first holding section 2 and the second holding section 4 that hold the ADF unit 13 rotatably relative to the scanner unit 9 are provided on both the left and right sides of the rear section 14 of the device. The board placement section 19 is provided between the first holding section 2 and the second holding section 4 in the left-right direction (X-axis direction). Furthermore, the ADF unit 13 includes a transport section including transport rollers 8 that transport the document 5, and a drive section 31 that drives the transport section. The board placement section 19 is provided between the holders 2, 4 and the drive section 31 in the depth direction (Y-axis direction).

[0054] 6, 7, and 10, the wiring 29 is guided by a guide portion 43, and the guide portion 43 is provided so as to be rotatable with respect to the ADF unit 13. The wiring 29 passes through the guide portion 43 and is guided from the inside to the outside of the ADF unit 13. Guide portion 43 is rotatably attached to mounting portion 42 of ADF unit 13 by shaft 40. In this state, guide portion 43 is inserted into mounting portion 44 (FIG. 7) of scanner unit 9. This allows ADF unit 13 to rotate around shaft 40 relative to scanner unit 9.

[0055] <Replacing the first and second boards> First, remove the rear cover 22 (FIG. 1) located at the rear 14 of the ADF unit 13, and then remove the top cover 24 (FIG. 3). This exposes the board placement section 19, allowing for work such as replacing the first board 15 and the second board 17 (FIGS. 2 and 7). Next, by removing two screws 32, it becomes possible to pull upward the mounting member 39 to which the first board 15 located on the outside of the rear portion 14 is attached. With this removed, by removing six screws 36 (FIG. 8), it becomes possible to remove the first board 15 from the mounting member 39. At this time, by removing the wiring 21 and the wiring 25, 27, and 29 from the connection portion with the first board 15, the first board 15 becomes free. Then, the first substrate 15 to be replaced is removed, replaced with a new first substrate 15, and the above-described procedure is repeated in reverse to complete the replacement work.

[0056] To replace second board 17, removing three screws 34 in the state shown in Fig. 7 makes it possible to pull out mounting member 41 to which second board 17 is attached in the upward direction. With this removed, removing six screws 38 (Fig. 9) makes it possible to remove second board 17 from mounting member 41. At this time, by removing wire 21 and wires 25, 27, and 29 from the connection portion with second board 17, second board 17 becomes free. Then, the second substrate 17 to be replaced is removed, replaced with a new second substrate 17, and the replacement work is completed by following the above steps in reverse.

[0057] <Explanation of Effects of the Embodiment> (1) According to this embodiment, first board 15 and second board 17 are provided in board placement section 19 of ADF unit 13. As a result, first board 15 for scanner unit 9 and second board 17 for ADF unit 13 are both provided within ADF unit 17, eliminating the need to ensure installation space for placing each control board in each of scanner unit 9 and ADF unit 13, thereby preventing the device from becoming larger. Furthermore, when it becomes necessary to replace either or both of the first substrate 15 and the second substrate 17, the replacement work only needs to be performed on the ADF unit 13, making the work easier.

[0058] (2) Furthermore, according to this embodiment, by placing the first substrate 15 in a direction intersecting the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-back or left-right direction, can be reduced. (3) Furthermore, according to this embodiment, by placing the second substrate 17 in a direction intersecting the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-back or left-right direction, can be reduced. (4) Furthermore, according to this embodiment, by placing both the first substrate 15 and the second substrate 17 in a direction that intersects the horizontal direction, for example, vertically, it is possible to more effectively prevent the size of the device in the horizontal direction, for example, the front-to-back direction, from increasing. Furthermore, first substrate 15 and second substrate 17 overlap when viewed in the horizontal direction, so that the size of the device in the horizontal direction, for example, the left-right direction, can be reduced.

[0059] (5) Furthermore, according to this embodiment, first board 15 is disposed on the outer side of second board 17. Therefore, when removing only first board 15 for maintenance or the like, there is no need to remove second board 17 or wiring 25, 27, 29 connected to second board 17. This simplifies the removal process. Furthermore, by placing the first board 15 directly above the wiring outlets 26 and 28 of the scanner unit 9, the wiring route of the scanner unit 9 can be prevented from becoming complicated. (6) Furthermore, according to this embodiment, the area 23 where the first substrate 15 and the second substrate do not overlap when viewed horizontally is used as installation space for the wiring 21 connecting the first substrate 15 and the second substrate 17, thereby preventing the device size from increasing due to the wiring 21 protruding. Furthermore, by concentrating the wiring 21, 25, 27, and 29 in the rear portion 14 at the rear of the device, these wirings can be made short and simple. Furthermore, since the wiring work can be done in one place, the work becomes easier. (7) Furthermore, according to this embodiment, the wiring 21, 25, 27, and 29 connected to the first substrate 15 or the second substrate 17 are included in the region of the substrates 15 and 17 in the first direction (Z-axis direction). As a result, the wiring 21, 25, 27, and 29 do not protrude upward or downward relative to the substrates 15 and 17, thereby reducing the height dimension of the device.

[0060] (8) Furthermore, according to this embodiment, the first substrate 15 and the second substrate 17 provided in the substrate placement section 19 are provided between the first holding section 2 and the second holding section 4, thereby reducing the size in the left-right direction. (9) Furthermore, according to this embodiment, the first substrate 15 and the second substrate 17 provided in the substrate placement section 29 are provided between the holding sections 2, 4 and the drive section 31, so that the size in the left-right and front-back directions can be reduced.

[0061] (10) Furthermore, according to this embodiment, the cable 37 such as an FFC used to receive data read from the second surface 11 overlaps with the board placement section 19, thereby preventing the device from becoming larger due to the cable 37. Furthermore, by consolidating the cable 37 and the wires 21, 25, 27, and 29 at the rear 14 of the device, the length of the cable 37 and the wires 21, 25, 27, and 29 can be shortened, resulting in a simple structure. Furthermore, since the wiring work can be done in one place, the work becomes easier. (11) Furthermore, according to this embodiment, the first board 15 and the second board 17 are detachably attached to the board placement section 19 by the attachment members 39 and 41, and the attachment members 39 and 41 are inserted and removed along a first direction that intersects with the horizontal direction. As a result, the attachment direction of the first board 15 and the second board 17 via the attachment members 39 and 41 is the same as the insertion and removal direction of the attachment members 39 and 41, which makes it easier to perform the attachment and removal work and also makes it easier to ensure work space.

[0062] (12) Furthermore, the recording device 100 according to this embodiment includes the image reading device 1 and the recording unit 3 that can perform recording based on data read by the image reading device 1. This prevents the recording device 100, which records the results of reading by the image reading device 1 on a medium, from becoming larger in size. (13) Furthermore, according to this embodiment, the recording unit 3 has a main board 35 that controls the entire device, and the main board 35 is connected to the first board 15 or the second board 17 by wiring 29. This enables information to be exchanged between the image reading device 1 and the recording unit 3. (14) Furthermore, according to this embodiment, the wiring 29 is guided by the guide portion 43, and the guide portion 43 is provided rotatably relative to the ADF unit 13. This allows the wiring 29 to be guided with a simple configuration, and also improves the appearance. (15) Furthermore, according to this embodiment, the recording unit 3 has a main board 35 that controls the entire device, and the main board 35 overlaps with the board placement section 19 when viewed in a first direction (Z-axis direction) that intersects with the horizontal direction. Because the main board 35 overlaps with the board placement section 19 in this way, the size of the device can be effectively reduced.

[0063] <Scanner unit cosmetic line mounting structure; Figures 11 and 12> As shown in Figure 11, a decorative line 51 may be provided on a part of an upper case 50 that forms part of the case of the scanner unit 9. A lower case 52 is attached to the bottom of the upper case 50 with a plurality of screws 57. The decorative line 51 is provided from the perspective of design, etc., and therefore is a different color from the upper case 50 and the lower case 52. For example, the upper case 50 is white, the decorative line 51 is blue, and the lower case 52 is black. 12, a groove 53 is formed along the edge of the top surface of upper case 50. The inside of groove 53 is isolated from the inside of scanner unit 9, and is configured to prevent liquids such as water or small foreign objects that enter groove 53 from entering the inside of scanner unit 9. On one side, the cosmetic line 51 is provided with a convex portion 54 that protrudes downward at the upper part of the main body 56. The cosmetic line 51 is assembled to the upper case 50 by fitting the convex portion 54 into the groove 53. Further, at the lower part of the main body 56 of the cosmetic line 51, L-shaped pieces 55 protrude from the inner surface thereof as shown in FIG. 12. A plurality of these L-shaped pieces 55 are provided at intervals in the longitudinal direction of the cosmetic line 51. The lower case 52 is provided with an insertion portion 58 that is inserted into a U-shaped concave portion 59 between the L-shaped piece 55 and the main body 56 of the cosmetic line 51. With the convex portion 54 of the cosmetic line 51 fitted into the groove 53 of the upper case 50, the insertion portion 58 of the lower case 52 is inserted into the U-shaped concave portion 59 of the cosmetic line 51, thereby completing the assembly of the upper case 50, the cosmetic line 51, and the lower case 52. In this state, it is fixed with screws 57. Although the cosmetic line 51 is not directly fixed with screws 57, it is attached as described above so that it does not accidentally come off.

[0064] <Frame structure forming the conveyance path of the ADF unit; FIGS. 13 and 14> As shown in FIG. 13, the main frame 60 that forms the conveyance path for conveying the document 5 of the ADF unit 13 is formed of a resin material. The main frame 60 has a conveyance support surface portion 61 that supports the document 5 and side surface portions 62, 63 located on both sides, and generally forms a substantially H shape. The main frame 60, which is entirely formed of a resin material, has lower resistance to deformation against external forces compared to those made of sheet metal, for example, it is easily twisted. Therefore, here, sheet-metal reinforcing frames 64, 65 are integrally joined to the side surface portions 62, 63 to enhance the resistance to deformation. Specifically, the reinforcing frame 64 is fixed to the side surface portion 62 by a plurality of screws 66 in a surface-contact state. On one hand, the reinforcing frame 65 is fixed to the side surface portion 63 by screws 68 via a cushioning material 67 such as a rubber material. As shown in the partially enlarged cross-sectional view in Fig. 14, the reinforcing frame 65 has a gap 69 between it and the side surface portion 63. Since a driving part such as a motor is attached to the side surface portion 63, vibration occurs. The cushioning material 67 and the gap 69 suppress the transmission of the vibration to the main frame 60. On the other hand, since no driving part such as a motor is attached to the side surface portion 62, no cushioning material is provided as described above.

[0065] <Holding Structure for Open State of ADF Cover; Figs. 15 to 17> When the ADF unit 13 conveys the document 5, paper jams, i.e., jams may occur. The ADF cover 70 is configured to be rotatable in the vertical direction to open and close so that a process for eliminating the jam can be performed. Fig. 15 shows the state where the ADF cover 70 is closed, and Fig. 16 shows the state where the ADF cover 70 is open. As shown in Fig. 15, the ADF cover 70 has a lock stacker 71 on the side surface below the rotation fulcrum (not shown). This lock stacker 71 is provided one on one side of the ADF cover 70. Incidentally, it may be provided one on each side. In that case, it is desirable that both on both sides have the same structure. The lock stacker 71 is configured such that a spring force is applied in the direction in which the semi-protruding spherical surface portion 72 protrudes outward, and it stops at that position with a predetermined protrusion amount. When the ADF cover 70 is in the closed state, as shown in Fig. 15, the semi-protruding spherical surface portion 72 of the lock stacker 71 is at an external position where it does not face the side surface portion 63 of the main frame 60. On the other hand, as shown in Fig. 16, when the ADF cover 70 rotates around the rotation fulcrum and shifts to the open state, the part of the lock stacker 71 moves to an internal position facing the side surface portion 63 of the main frame 60 and becomes invisible from the outside. As shown in the partially enlarged cross-sectional perspective view in Figure 16, when the ADF cover 70 reaches the end position of its open state, the semi-spherical convex portion 72 of the lock stacker 71 enters a hole 73 provided at a corresponding position on the side surface 63 due to the spring force, and the ADF cover 70 is locked. This maintains the open state of the ADF cover 70. When the ADF cover 70 is rotated in the closing direction, the semi-spherical convex portion 72 is pushed back against the spring force, sliding along the surface of the opposing side surface 63, and reaches the end position of its closed state (Figure 15). In the figure, reference numeral 74 denotes the lock stacker 71, and reference numeral 75 denotes a spring that applies the spring force. 17 shows another example of the structure for holding the ADF cover in the open state. In this example, a curved long groove 80 is formed in the side of the ADF cover 70, and a boss 81 is provided to protrude from the corresponding side surface portion 63. The boss 81 is capable of sliding longitudinally within the long groove 80. The long groove 80 and boss 81 are provided on both sides of the ADF cover 70, but because they have the same structure, only one of them will be described here. One end 82 of the long groove 80 is engaged with the boss 81 to hold the ADF cover 70 in the open position, and the other end 83 of the long groove 80 is engaged with the boss 81 to hold the ADF cover 70 in the closed position.

In the above embodiment, both the first substrate 15 and the second substrate 17 are arranged vertically, but only one of them may be arranged vertically. Furthermore, although the "portrait orientation" is preferably vertical, it is not limited to being vertical and may be arranged at an angle. In the above embodiment, the first board 15 is disposed outside the second board 17, but the second board 17 may be disposed outside the first board 15. In this case, the main board 35 is connected to the second board 17. [Explanation of symbols]
