[0032] Hereinafter, the present invention will first be briefly described.
[0033] In order to solve the above-mentioned problems, the image reading device involved in the first embodiment of the present invention is characterized in that it comprises: a scanner unit, which reads an original document; a document conveying unit, which is arranged above the scanner unit, and the document conveying unit conveys the original document and can read the original document; a first substrate, which controls the movement of the scanner unit; and a second substrate, which controls the movement of the document conveying unit, and the first substrate and the second substrate are arranged in a substrate configuration part of the document conveying unit.
[0034] According to this method, the first substrate and the second substrate are arranged in the substrate arrangement portion of the document conveying unit. Thus, since the first substrate for the scanner unit and the second substrate for the document conveying unit are both arranged in the document conveying unit, it is not necessary to ensure the arrangement space for arranging each control substrate on the scanner unit and the document conveying unit, respectively, and the enlargement of the device can be suppressed.
[0035] Furthermore, when it is necessary to replace one or both of the first substrate and the second substrate, it is only necessary to perform work for replacement on the document transport unit, so the work is easy.
[0036] An image reading device according to a second aspect of the present invention is characterized in that, in the first aspect, the first substrate is arranged to extend in a first direction intersecting the horizontal direction.
[0037] According to this aspect, by orienting the first substrate in a direction intersecting the horizontal direction, for example, in a vertical direction, it is possible to suppress the dimension in the horizontal direction, that is, the dimension in the front-rear direction or the left-right direction.
[0038] An image reading device according to a third aspect of the present invention is characterized in that, in the first aspect or the second aspect, the second substrate is arranged to extend in a first direction intersecting with the horizontal direction.
[0039] According to this aspect, by orienting the second substrate in a direction intersecting the horizontal direction, for example, in a vertical direction, it is possible to suppress the dimension in the horizontal direction, that is, the dimension in the front-rear direction or the left-right direction.
[0040] 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 intersecting a horizontal direction, and the first substrate and the second substrate overlap when viewed from the horizontal direction.
[0041] According to this aspect, by placing both the first substrate and the second substrate in a direction intersecting the horizontal direction, for example, vertically, it is possible to more effectively suppress an increase in the size of the device in the horizontal direction, for example, in the front-rear direction.
[0042] In addition, by overlapping the first substrate and the second substrate when viewed in the horizontal direction, the size of the device in the horizontal direction, for example, the left-right direction, can be suppressed.
[0043] An image reading device according to a fifth aspect of the present invention is characterized in that, in the fourth aspect, the first substrate is arranged on an outer side of the document feeding unit than the second substrate.
[0044] According to this aspect, when only the first substrate is removed for maintenance or the like, it is not necessary to remove the second substrate or wiring connected to the second substrate, so the work is simplified.
[0045] The image reading device involved in the sixth aspect of the present invention is characterized in that, in the fourth aspect or the fifth aspect, it has a wiring connecting the first substrate and the second substrate, and the area of the first substrate and the second substrate that does not overlap when viewed from the horizontal direction overlaps with the wiring when viewed from the horizontal direction.
[0046] Here, the “overlapping with the wiring when viewed from the horizontal direction” in “the non-overlapping area of the first substrate and the second substrate when viewed from the horizontal direction overlaps with the wiring when viewed from the horizontal direction” means that the wiring connecting the first substrate and the second substrate is arranged through the non-overlapping area.
[0047] According to this aspect, by using the non-overlapping area between the first substrate and the second substrate as the installation space for the wiring, it is possible to suppress the increase in device size due to the protrusion of the wiring. In addition, by passing the wiring through the non-overlapping area, its length can be shortened.
[0048] In addition, if the wiring is concentrated around the substrate configuration portion at the rear of the device, the wiring can be shortened and made simple. In addition, since the wiring operation can be performed at one place, the operation becomes easy.
[0049] The image reading device according to the 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 the area of the substrate in the first direction.
[0050] 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. Thus, since the wiring does not protrude vertically relative to the substrate, the height dimension of the device can be reduced.
[0051] The image reading device involved in the eighth aspect of the present invention is characterized in that, in any one of the first aspect to the seventh aspect, the image reading device has a first holding portion and a second holding portion for rotatably holding the original feeding unit relative to the scanner unit, and the substrate configuration portion is arranged between the first holding portion and the second holding portion.
[0052] Here, the phrase “the substrate configuration portion is disposed between the first holding portion and the second holding portion”, “is disposed between the first holding portion and the second holding portion”, means that it may not be completely accommodated therebetween, for example, it only needs to be disposed between the respective outer ends of the first holding portion and the second holding portion in the left-right direction.
[0053] According to this aspect, since the first substrate and the second substrate provided in the substrate placement portion are provided between the first holding portion and the second holding portion, the dimension in the left-right direction can be suppressed.
[0054] The image reading device involved in the ninth aspect of the present invention is characterized in that, in any one of the first aspect to the seventh aspect, the image reading device has a holding portion that rotatably holds the document conveying unit relative to the scanner unit, the document conveying unit has a conveying portion that conveys the document and a driving portion that drives the conveying portion, and the substrate configuration portion is arranged between the holding portion and the driving portion.
[0055] Here, the phrase “between the holding portion and the driving portion” in “the substrate configuration portion is disposed between the holding portion and the driving portion” means that the substrate configuration portion may not be completely accommodated therebetween, for example, it only needs to be disposed between the respective outer ends of the holding portion and the driving portion in the left-right direction and the front-back direction.
[0056] According to this aspect, since the first substrate and the second substrate provided in the substrate placement portion are provided between the holding portion and the driving portion, the dimensions in the left-right direction and the front-back direction can be suppressed.
[0057] In any one of the first to ninth aspects, the scanner unit may include a cable for transmitting data obtained by reading the document to the first substrate, and the substrate placement portion may be arranged to overlap the cable when viewed in a horizontal direction.
[0058] According to this arrangement, a cable such as an FFC for receiving data obtained by reading the second surface overlaps with the substrate arrangement portion, so that an increase in size of the device due to the cable can be suppressed.
[0059] In addition, if the cables and the wiring are concentrated at the rear of the device, the length of the cables or the wiring can be shortened, resulting in a simple structure. In addition, since the wiring work can be performed at one place, the work becomes easy.
[0060] The image reading device involved in the tenth aspect of the present invention is characterized in that, in any one of the first aspect to the ninth aspect, at least one of the first substrate and the second substrate is freely and detachably mounted on the substrate configuration portion by a mounting component, and the mounting component is inserted and removed along a first direction intersecting the horizontal direction.
[0061] According to this aspect, by making the mounting direction of at least one of the first substrate and the second substrate via the mounting member the same as the insertion and removal direction of the mounting member, the attachment and detachment work can be easily performed and the work space can be easily ensured.
[0062] The recording device according to the eleventh aspect of the present invention is characterized in that the recording device comprises: the image reading device of 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.
[0063] According to this aspect, in the recording device that records the reading result of the image reading device on a medium, it is possible to suppress an increase in size.
[0064] The recording device according to the twelfth aspect of the present invention is characterized in that, in the eleventh aspect, the recording unit has a control substrate for controlling the entire device, and the control substrate is connected to the first substrate or the second substrate via wiring.
[0065] According to this aspect, the recording unit includes a control substrate for controlling the entire device, and the control substrate is connected to the first substrate or the second substrate via wiring. Thus, information can be exchanged between the image reading device and the recording unit.
[0066] A recording device according to a thirteenth aspect of the present invention is characterized in that, in the twelfth aspect, the wiring is guided by a guide portion, and the guide portion is provided to be rotatable relative to the document feeding unit.
[0067] According to this aspect, the wiring is guided by the guide portion, and the guide portion is provided to be rotatable relative to the document feeding unit. Thus, the wiring can be guided with a simple structure, and the appearance can also be improved.
[0068] The recording device involved in the fourteenth aspect of the present invention is characterized in that, in the eleventh aspect, the recording unit has a control substrate for controlling the entire device, and when viewed from a first direction intersecting the horizontal direction, the control substrate overlaps with the substrate configuration portion.
[0069] According to this embodiment, the recording unit has a control substrate for controlling the entire device, and when viewed from a first direction intersecting the horizontal direction, the control substrate overlaps the substrate arrangement portion. Thus, the control substrate overlaps the substrate arrangement portion, so the size of the device can be effectively reduced.
[0070] [Implementation Method]
[0071] The following is based on Figures 1 to 12 An image reading device according to an embodiment of the present invention and a recording device including the image reading device will be described in detail.
[0072] In the following description, as shown in each figure, three mutually orthogonal axes are respectively set as X-axis, Y-axis, and Z-axis. The Z-axis direction is equivalent to the vertical direction (the direction in which gravity acts). The X-axis direction and the Y-axis direction are equivalent to the horizontal direction.
[0073] like Figure 5 As shown, the recording device 100 of the present embodiment includes an image reading device 1 and a recording unit 3 capable of performing recording based on data read by the image reading device 1 .
[0074] In this embodiment, the recording unit 3 is an inkjet printer, which uses a conveying roller to convey a medium such as printing paper (not shown) contained in a medium box to a recording execution unit composed of a recording head, etc., and then records by ejecting ink. The recording unit 3 can perform recording based on data read by the image reading device 1.
[0075] like Figure 5 As shown, the image reading device 1 includes a scanner unit 9 for reading a document 5 and an ADF unit 13 provided above the scanner unit 9 and capable of feeding and reading the document 5. The ADF unit 13 is an automatic document feeder, which is an example of a document feeder.
[0076] In addition, if Figure 2 and Figure 4 As shown, the ADF unit 13 includes a first substrate 15 for controlling the operation of the scanner unit 9 and a second substrate 17 for controlling the operation of the ADF unit 13. The first substrate 15 and the second substrate 17 are both disposed on a substrate placement portion 19 of the ADF unit 13. The substrate placement portion 19 is located at the rear portion 14 of the ADF unit 13 in the front-rear direction.
[0077] like Figure 1 and Figure 2 As shown, the ADF unit 13 is rotatably mounted on the scanner unit 9 located below through a pair of left and right hinges located at the rear portion 14, namely the first holding portion 2 and the second holding portion 4. That is, the front portion 16 of the ADF unit 13 is mounted on the scanner unit 9 as a free end so as to be openable and closable.
[0078] Hereinafter, each component will be described in detail.
[0079] <Scanner unit>
[0080] In the present embodiment, the scanner unit 9 places the document 5 on a transparent document placement plate (not shown) by making the ADF unit 13 "open" relative to the scanner unit 9, so that a scanner reading unit (not shown) such as a line imaging sensor located below the document placement plate reads the document 5. The scanner reading unit moves along the reading surface of the document 5 in the device width direction (X-axis direction) when performing the reading.
[0081] Note that, the illustration of the state in which the document 5 is placed on the document placement plate and the document is read by the reading section on the scanner side is omitted because it is a well-known range.
[0082] <ADF unit>
[0083] like Figure 1 and Figure 5 As shown in FIG. 1 , the ADF unit 13 is in a “closed” state relative to the scanner unit 9, and uses a conveying unit to convey the original document 5 placed on the supply tray 6 along the conveying path. The conveying unit is composed of a known pickup roller (not shown) and a conveying roller 8 ( Figure 4 ) etc. The conveying path has a U-shaped inverting portion 10, and the document 5 conveyed along the conveying path is discharged onto a discharge tray 12. The discharge tray 12 is located above the document placement plate of the scanner unit 9.
[0084] When the document 5 is conveyed through the U-shaped reversing section 10 , the document 5 is read by an ADF reading section (not shown) such as a line imaging sensor. The ADF reading section is configured to read an image of the second surface 11 of the document 5 placed on the supply tray 6 and in contact with the supply tray 6 .
[0085] Note that the illustration of the state in which the document 5 transported by the transport roller 8 is read by the ADF reading section is omitted because it is a well-known range.
[0086] In this embodiment, the ADF unit 13 is provided with a back cover 22 detachably at its rear portion 14. When the back cover 22 is removed, an upper surface cover 24 ( Figure 3 ) covers the substrate arrangement portion 19 from above. The upper surface cover 24 is also detachable, and by removing the upper surface cover 24, the substrate arrangement portion 19 is exposed, and the first substrate 15 and the second substrate 17 can be replaced.
[0087] from Figure 1 The state of removing the back cover 22 is Figure 3 status, from Figure 3 The state in which the upper surface cover 24 is removed is Figure 2 status.
[0088] The upper surface cover 24 is detachably mounted on the mounted portion of the ADF unit 13 by two screws 30. The rear surface cover 22 is also detachably mounted on the mounted portion of the ADF unit 13 by a plurality of screws (not shown).
[0089] 《When images are formed on both sides of the original》
[0090] The image reading device 1 of this embodiment is configured so that, when images are formed on both sides of the original document 5, the images on both sides can be read at once. That is, when the original document 5 set on the supply tray 6 is conveyed on the conveying path having the U-shaped reversing portion 10 by the conveying mechanism, the original document 5 passes between the ADF reading portion and the scanner reading portion. When passing through, the scanner reading portion does not move but is in a stopped state. Thus, the images on both sides of the original document 5 can be read at once using the ADF reading portion and the scanner reading portion.
[0091] Specifically, in Figure 5 In the embodiment, the second side 11 of the document 5 placed on the feeding tray 6 is read by the ADF reading unit, and the first side 7 opposite to the second side 11 of the document 5 is read by the scanner reading unit in a stopped state.
[0092] <Substrate placement portion, first substrate, second substrate>
[0093] In the present embodiment, as described above, the substrate arrangement portion 19 is located at the rear portion 14 of the ADF unit 13. Furthermore, the first substrate 15 is arranged to extend in a direction intersecting the horizontal direction. In addition, the second substrate 17 is also arranged to extend in a direction intersecting the horizontal direction. That is, both the first substrate 15 and the second substrate 17 are arranged in the substrate arrangement portion 19 in a manner extending in a first direction intersecting the horizontal direction.
[0094] Specifically, if Figure 2 and Figure 4 As shown in FIG. 1 , the first substrate 15 and the second substrate 17 are arranged vertically in the substrate arrangement portion 19. The first substrate 15 and the second substrate 17 are arranged in a mutually parallel state so as to overlap when viewed from the horizontal direction. Here, the substrate arrangement portion 19 is a region where the first region 18 occupied by arranging the first substrate 15 there and the second region 20 occupied by arranging the second substrate 17 there are combined.
[0095] It should be noted that the "longitudinal" does not need to be vertical in the strict sense, but can be inclined within the scope of the effect of the present invention. In addition, the "parallel" does not need to be parallel in the strict sense, but can deviate from parallel within the scope of the effect of the present invention.
[0096] In addition, in this embodiment, Figure 2 and Figure 4 It is understood that the first substrate 15 is arranged outside the second substrate 17. Here, by placing the first substrate 15 right above the wiring outlet 28 of the scanner unit 9, it is possible to suppress the wiring path of the scanner unit 9 from becoming complicated.
[0097] <Wiring>
[0098] In addition, if Figure 6 and Figure 7 As shown, in this embodiment, there is a wiring 21 connecting the first substrate 15 and the second substrate 17. In addition, the area 23 of the first substrate 15 and the second substrate 17 that does not overlap when viewed from the horizontal direction is arranged to overlap with the wiring 21 when viewed from the horizontal direction. Figure 6 and Figure 7 It can be understood that the “non-overlapping region 23 viewed from the horizontal direction” refers to a region produced by the first substrate 15 and the second substrate 17 being arranged offset in the width direction (X-axis direction) of the device.
[0099] The wiring 21 enables signal exchange between the first substrate 15 and the second substrate 17. For example, when the ADF reading unit and the scanner reading unit are used to read images of both sides of the original 5 at once, the data read by the scanner reading unit is sent from the first substrate 15 to the second substrate 17 via the wiring 21. It should be noted that the scanner reading unit and the second substrate 17 may be directly connected by wiring, and the read data may be directly sent to the second substrate 17.
[0100] Here, “overlapping with the wiring 21 when viewed in the horizontal direction” means that the wiring 21 connecting the first substrate 15 and the second substrate 17 is arranged through the non-overlapping region 23 .
[0101] The wiring 21 is a wiring that connects the first substrate 15 and the second substrate 17 , but is not limited thereto.
[0102] That is, in Figure 6 In the embodiment, the wiring 21 extends so as to intersect with an extension line of the first substrate 15 provided on the outer side of the second substrate 17 .
[0103] Therefore, when the first substrate 15 and the second substrate 17 do not have a “region that does not overlap when viewed in the horizontal direction”, the wiring is routed outside the substrate arrangement portion, and there is a possibility that the size of the device will increase due to the wiring space.
[0104] In contrast, in this embodiment, the wiring 21 extending in a manner intersecting the extension line of the first substrate 15 is arranged to overlap with the "non-overlapping area viewed from the horizontal direction" of the first substrate 15 and the second substrate 17, thereby suppressing the enlargement of the device due to the wiring space.
[0105] In addition, if Figure 6 and Figure 7 As shown, in addition to the wiring 21, there are also wirings 25, 27, 29 connected to the first substrate 15 or the second substrate 17. The wirings 25, 27, 29 are connected to various sensors or actuators such as motors. The wiring 21 and the wirings 25, 27, 29 are arranged to be included in the first direction of the first substrate 15 and the second substrate 17, that is, the "longitudinal" area. In other words, the wiring 21 and the wirings 25, 27, 29 are arranged to be routed in the left-right direction (X-axis direction) and the depth direction (Y-axis direction) so that they do not protrude in the up-down direction (Z-axis direction) of the first substrate 15 and the second substrate 17.
[0106] The wiring 21 and the wirings 25, 27, and 29 that connect the first substrate 15 and the second substrate 17 have a connector that can route the wiring 21 and the wirings 25, 27, and 29 in the horizontal direction (X-axis direction) and the depth direction (Y-axis direction). In addition, by removing the wiring 21 and the wirings 25, 27, and 29 from the connector, the first substrate 15 and the second substrate 17 are separated from each wiring and become free, and can be easily removed from the ADF unit 13.
[0107] In addition, the wiring 21 and the wirings 25 , 27 , and 29 are gathered at the rear portion of the ADF unit 13 .
[0108] It should be noted that in this figure, although part of the wirings 25, 27, and 29 are omitted from the illustration to avoid complicating the illustration, these wirings are also configured in the same way as the illustrated wirings so as not to protrude in the vertical direction (Z-axis direction) between the first substrate 15 and the second substrate 17.
[0109] Here, the wiring 25 is drawn out from the first substrate 15 and connected to a driving mechanism (not shown) of the scanner unit 9. The wiring 25 is introduced into the scanner unit 9 from the ADF unit 13 through the wiring outlet 26.
[0110] The wiring 27 is drawn from the second substrate 17 and connected to the drive unit 31 ( Figure 2 The second substrate 17 is located on the right side of the driving unit 31.
[0111] The wiring 29 is shown as being led out from the first substrate 15 and connected to the main substrate 35 ( Figure 5 The main board 35 is an example of a control board that controls the entire device. The wiring 29 is introduced from the ADF unit 13 into the recording unit 3 through the wiring outlet 28.
[0112] like Figure 5 As shown, 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. Thus, the recording unit 3 can perform recording based on the data read by the image reading device 1.
[0113] In the present embodiment, the main substrate 35 is arranged so as to overlap with the substrate arrangement portion 19 when viewed from the first direction, that is, when viewed from the longitudinal direction.
[0114] Specifically, the main substrate 35 is arranged at the rear portion in the front-rear direction of the recording unit 3. In addition, the main substrate 35 is arranged in the "vertical direction" at a position that is substantially the same rear portion as the first substrate 15 in the area below the wiring outlet 28. In other words, the surface formed by the main substrate 35 and the surface formed by the first substrate 15 are arranged in a state that is regarded as substantially one surface. Here, "a state that is regarded as substantially one surface" means that as long as the above-mentioned overlap is achieved, either one may extend.
[0115] <Scanner unit cable>
[0116] like Figure 7 As shown in the figure, in this embodiment, the scanner unit 9 is provided with a cable 37, and the cable 37 transmits the data obtained by reading the original 5 by the reading part (not shown) to the first substrate 15. The cable 37 is composed of FFC (flexible flat cable). In addition, the substrate arrangement part 19 is arranged so as to overlap with the cable 37 when viewed from the horizontal direction. Thus, since the cable 37 is arranged at a position in the width direction of the board arrangement part, the necessary length of the cable 37 can be shortened.
[0117] Furthermore, since the cable 37 can be connected by being pulled out directly upward without being routed to the left and right, the length can be more effectively reduced.
[0118] The cable 37 is 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 free from the cable 37 and can be easily detached from the ADF unit 13.
[0119] like Figure 7 As shown, in this embodiment, the first substrate 15 and the second substrate 17 are detachably mounted on the substrate arrangement portion 19 by mounting components 39 and 41, respectively. In addition, the mounting components 39 and 41 are configured to be pluggable and removable along a first direction intersecting the horizontal direction, that is, the up-down direction. Here, the mounting components 39 and 41 are configured by shielding plates made of metal plates, and have a shape and structure that can hold the respective substrates 15 and 17 to be held.
[0120] Specifically, the mounting member 39 is mounted on the mounted portion of the ADF unit 13 by two screws 32, and the mounting member 41 is mounted on the mounted portion of the ADF unit 13 by three screws 34. By removing these screws 32 and 34, the mounting members 39 and 41 can be pulled out upward.
[0121] In addition, if Figure 8 As shown, the first substrate 15 is detachably mounted on the mounting member 39 by six screws 36. The first substrate 15 can be removed from the mounting member 39 by removing all the screws 36.
[0122] In addition, if Fig. 9 As shown, the second substrate 17 is detachably mounted on the mounting member 41 by means of six screws 38. By removing all the screws 38, the second substrate 17 can be removed from the mounting member 41. It should be noted that Fig. 9 is from Figure 8 This is a diagram showing the entire second substrate 17 after the first substrate 15 is removed.
[0123] like Figure 2 As shown, as described above, the first holding part 2 and the second holding part 4 are provided on both sides of the rear part 14 for rotatably holding the ADF unit 13 relative to the scanner unit 9. The substrate arrangement part 19 is provided between the first holding part 2 and the second holding part 4 in the left-right direction (X-axis direction).
[0124] The ADF unit 13 includes a conveying section including conveying rollers 8 and the like for conveying the document 5 and a driving section 31 for driving the conveying section. The substrate placement section 19 is provided between the holding sections 2 and 4 and the driving section 31 in the depth direction (Y-axis direction).
[0125] In addition, if Figure 6 , Figure 7 and Fig.10As shown, the wiring 29 is guided by the guide portion 43, and the guide portion 43 is provided to be rotatable relative to the ADF unit 13. The wiring 29 passes through the guide portion 43 and is guided from the inside of the ADF unit 13 to the outside.
[0126] The guide portion 43 is rotatably mounted on the mounted portion 42 of the ADF unit 13 via the shaft 40. In this state, the guide portion 43 is inserted into the mounted portion 44 ( Figure 7 ). Thus, the ADF unit 13 can rotate around the axis 40 relative to the scanner unit 9.
[0127] <Replacement of the first and second substrates>
[0128] First, remove the back cover 22 ( Figure 1 ), then remove the upper surface cover 24 ( Figure 3 ). As a result, the substrate arrangement portion 19 is exposed, and the first substrate 15 and the second substrate 17 can be replaced. ( Figure 2 , Figure 7 ).
[0129] Next, by removing the two screws 32, the mounting member 39 to which the first substrate 15 located outside the rear portion 14 is mounted can be pulled out upward. By removing the six screws 36 ( Figure 8 ), the first substrate 15 can be removed from the mounting member 39. At this time, by removing the wiring 21 and the wirings 25, 27, and 29 from the connection portion with the first substrate 15, the first substrate 15 becomes free.
[0130] Then, the first substrate 15 to be replaced is removed and replaced with a new first substrate 15 , and the replacement operation is completed in the reverse order of the above.
[0131] The replacement operation of the second substrate 17 is performed by Figure 7 By removing the three screws 34 in the state, the mounting member 41 on which the second substrate 17 is mounted can be pulled out upward. By removing the six screws 38 ( Fig. 9 ), the second substrate 17 can be removed from the mounting member 41. At this time, by removing the wiring 21 and the wirings 25, 27, and 29 from the connection portion with the second substrate 17, the second substrate 17 becomes free.
[0132] Then, the second substrate 17 to be replaced is removed and replaced with a new second substrate 17, and the replacement operation is completed in the reverse order of the above.
[0133] <Description of Effects of Embodiment>
[0134] (1) According to the present embodiment, the first substrate 15 and the second substrate 17 are disposed on the substrate placement portion 19 of the ADF unit 13. Thus, since the first substrate 15 for the scanner unit 9 and the second substrate 17 for the ADF unit 13 are both disposed in the ADF unit 13, it is not necessary to separately ensure installation spaces for arranging the control substrates in the scanner unit 9 and the ADF unit 13, thereby suppressing the enlargement of the device.
[0135] Furthermore, when it is necessary to replace one or both of the first substrate 15 and the second substrate 17 , it is only necessary to perform work for replacing the ADF unit 13 , so the work is easy.
[0136] (2) According to the present embodiment, by arranging the first substrate 15 in a direction intersecting the horizontal direction, for example, in a vertical direction, the dimension in the horizontal direction, that is, the dimension in the front-rear direction or the left-right direction can be suppressed.
[0137] (3) According to the present embodiment, the second substrate 17 is disposed in a direction intersecting the horizontal direction, for example, vertically, so that the dimension in the horizontal direction, that is, the dimension in the front-rear direction or the left-right direction can be suppressed.
[0138] (4) According to the present embodiment, by placing both the first substrate 15 and the second substrate 17 in a direction intersecting the horizontal direction, for example, vertically, it is possible to more effectively suppress an increase in the size of the device in the horizontal direction, for example, in the front-rear direction.
[0139] Furthermore, by overlapping the first substrate 15 and the second substrate 17 when viewed in the horizontal direction, it is possible to suppress the size of the device in the horizontal direction, for example, in the left-right direction.
[0140] (5) According to the present embodiment, since the first substrate 15 is disposed outside the second substrate 17, when only the first substrate 15 is removed for maintenance, the second substrate 17 or the wirings 25, 27, 29 connected to the second substrate do not need to be removed. Therefore, the operation is simplified.
[0141] Furthermore, by providing the first substrate 15 right above the wiring outlets 26 and 28 of the scanner unit 9 , it is possible to suppress the wiring path of the scanner unit 9 from becoming complicated.
[0142] (6) According to the present embodiment, the region 23 where the first substrate 15 and the second substrate do not overlap when viewed in the horizontal direction is used as a space for installing the wiring 21 connecting the first substrate 15 and the second substrate 17, thereby preventing the device from being enlarged due to the protrusion of the wiring 21.
[0143] Furthermore, if the wirings 21, 25, 27, and 29 are concentrated in the rear portion 14, which is the rear of the device, these wirings can be shortened and simplified. In addition, since the wiring work can be performed in one place, the work becomes easy.
[0144] (7) In addition, according to the present embodiment, the wirings 21, 25, 27, 29 connected to the first substrate 15 or the second substrate 17 are included in the region in the first direction (Z-axis direction) of the substrates 15 and 17. Thus, the wirings 21, 25, 27, 29 do not protrude vertically relative to the substrates 15 and 17, so that the height dimension of the device can be suppressed.
[0145] (8) According to the present embodiment, since the first substrate 15 and the second substrate 17 provided in the substrate placement portion 19 are provided between the first holding portion 2 and the second holding portion 4 , the dimension in the left-right direction can be suppressed.
[0146] (9) According to the present embodiment, since the first substrate 15 and the second substrate 17 provided in the substrate placement portion 19 are provided between the holding portions 2 and 4 and the driving portion 31 , the dimensions in the left-right direction and the front-back direction can be suppressed.
[0147] (10) According to the present embodiment, the cable 37 such as an FFC for receiving data obtained by reading the second surface 11 overlaps with the board placement portion 19 , thereby suppressing an increase in the size of the device due to the cable 37 .
[0148] Furthermore, if the cables 37 and the wirings 21, 25, 27, 29 are gathered at the rear portion 14 of the device, the lengths of the cables 37 and the wirings 21, 25, 27, 29 can be shortened, resulting in a simple structure. Furthermore, since the wiring work can be performed at one place, the work becomes easy.
[0149] (11) In addition, according to the present embodiment, the first substrate 15 and the second substrate 17 are detachably mounted on the substrate arrangement portion 19 via the mounting members 39 and 41, and the mounting members 39 and 41 are inserted and removed along a first direction intersecting the horizontal direction. Thus, the mounting direction of the first substrate 15 and the second substrate 17 via the mounting members 39 and 41 is the same as the insertion and removal direction of the mounting members 39 and 41, so that the operation for the above-mentioned mounting and removal is easy to perform, and it is easy to ensure the working space.
[0150] (12) In addition, the recording device 100 according to the present embodiment includes the image reading device 1 and the recording unit 3 capable of performing recording based on the data read by the image reading device 1. Thus, in the recording device 100 that records the reading result of the image reading device 1 on a medium, it is possible to suppress an increase in size.
[0151] (13) According to this embodiment, the recording unit 3 includes a main substrate 35 for controlling the entire device, and the main substrate 35 is connected to the first substrate 15 or the second substrate 17 via the wiring 29. This allows information to be exchanged between the image reading device 1 and the recording unit 3.
[0152] (14) According to the present embodiment, the wiring 29 is guided by the guide portion 43, and the guide portion 43 is provided rotatably with respect to the ADF unit 13. Thus, the wiring 29 can be guided with a simple structure, and the appearance can be improved.
[0153] (15) In addition, according to the present embodiment, the recording unit 3 has a main substrate 35 for controlling the entire device, and when viewed from the first direction (Z-axis direction) intersecting the horizontal direction, the main substrate 35 overlaps with the substrate arrangement portion 19. In this way, since the main substrate 35 overlaps with the substrate arrangement portion 19, the size of the device can be effectively suppressed.
[0154] <Mounting structure of the decorative line of the scanner unit; Fig.11 and Fig.12 >
[0155] like Fig.11 As shown in FIG. 1 , a decorative line 51 is sometimes provided on a part of an upper housing 50 constituting a part of the housing of the scanner unit 9. A lower housing 52 is attached to the lower portion of the upper housing 50 by a plurality of screws 57. Since the decorative line 51 is provided from the viewpoint of design, a decorative line of a different color from that of the upper housing 50 and the lower housing 52 is used. For example, the upper housing 50 is white, the decorative line 51 is blue, and the lower housing 52 is black.
[0156] like Fig.12 As shown, a groove 53 is formed along the edge of the upper surface of the upper housing 50. The interior of the groove 53 is isolated from the interior of the scanner unit 9, and liquid such as water or small foreign matter entering the groove 53 does not enter the interior of the scanner unit 9.
[0157] On the other hand, in the decorative line 51, a convex portion 54 protruding downward is provided on the upper portion of the main body 56. The decorative line 51 is assembled to the upper case 50 by fitting its convex portion 54 into the groove 53. In addition, at the lower portion of the main body 56 of the decorative line 51, as shown in FIG. Fig.12 As shown in FIG. 1 , an L-shaped piece 55 is protrudingly provided on the inner surface thereof. A plurality of L-shaped pieces 55 are provided at intervals in the longitudinal direction of the decorative line 51 .
[0158] The lower case 52 is provided with an insertion portion 58 that is inserted into a U-shaped recess 59 between the L-shaped piece 55 and the main body 56 of the decorative line 51 .
[0159] With the convex portion 54 of the decorative line 51 inserted into the groove 53 of the upper shell 50, the insertion portion 58 of the lower shell 52 is inserted into the U-shaped recess 59 of the decorative line 51, thereby completing the assembly of the upper shell 50, the decorative line 51, and the lower shell 52. In this state, the decorative line 51 is fixed with screws 57. Although the decorative line 51 is not directly fixed with screws 57, it will not fall off accidentally by installing it as described above.
[0160] <Frame structure constituting the ADF unit conveying path; Fig.13 and Fig.14 >
[0161] like Fig.13 As shown, the main frame 60 of the ADF unit 13 forming the conveying path for conveying the original document 5 is formed of a resin material. The main frame 60 has a conveying support surface 61 for supporting the original document 5 and side surfaces 62 and 63 located on both sides, and is generally in an H shape. The main frame 60 formed entirely of a resin material has a lower resistance to deformation by external forces than a main frame made of a metal plate, for example, it is easy to twist. Therefore, here, metal plate reinforcement frames 64 and 65 are integrally joined to the side surfaces 62 and 63 to improve the resistance to deformation.
[0162] Specifically, the reinforcing frame 64 is fixed to the side surface portion 62 by a plurality of screws 66 in a surface contact state.
[0163] On the other 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. Fig.14 As shown in the partially enlarged cross-sectional view in FIG, there is a gap 69 between the reinforcing frame 65 and the side portion 63. Since a driving part such as a motor is installed on the side portion 63, vibration is generated. The buffer material 67 and the gap 69 suppress the transmission of the vibration to the main frame 60. On the other hand, since a driving part such as a motor is not installed on the side portion 62, no buffer material is provided as described above.
[0164] <Structure for maintaining the open state of the ADF cover; Figures 15 to 17 >
[0165] When the ADF unit 13 conveys the document 5, a paper jam may occur. In order to clear the paper jam, the ADF cover 70 is configured to be openable and closable by rotating in the vertical direction. Fig.15 The ADF cover 70 is closed. Fig.16 This is a state where the ADF cover 70 is opened.
[0166] like Fig.15As shown, the ADF cover 70 has a locking crimper 71 on the side below the rotation fulcrum (not shown). The locking crimper 71 is provided on one side of the ADF cover 70. It should be noted that one can also be provided on each side. In this case, it is preferred that the two on both sides have the same structure. The locking crimper 71 is configured to apply elastic force to the direction in which the semi-protruding spherical surface 72 protrudes outward, and stops at the position with a predetermined protruding amount.
[0167] When the ADF cover 70 is closed, Fig.15 As shown in FIG. 1 , the semi-spherical surface 72 of the locking crimping device 71 is located at an outer position not opposite to the side surface 63 of the main frame 60. Fig.16 As shown, when the ADF cover 70 rotates about the rotation fulcrum and transitions to the open state, the portion of the locking crimper 71 moves to an inner position opposite to the side surface portion 63 of the main frame 60 and cannot be seen from the outside.
[0168] like Fig.16 As shown in the partially enlarged sectional stereoscopic diagram in FIG, when the ADF cover 70 reaches the final opening position, the semi-spherical surface 72 of the locking crimper 71 enters the hole 73 provided at the corresponding position of the side surface 63 by the elastic force and becomes locked. Thus, the ADF cover 70 maintains its open state. When the ADF cover 70 is rotated in the closing direction, the semi-spherical surface 72 resists the elastic force and is pushed back, sliding on the surface of the opposite side surface 63 to reach the final closing position ( Fig.15 ). In the figure, reference numeral 74 denotes the locking crimping device 71, and reference numeral 75 denotes a spring for applying the elastic force.
[0169] Fig.17 This is another example of a structure for maintaining the open state of the ADF cover. In this example, a curved long groove 80 is formed on the side of the ADF cover 70, and a boss 81 is protrudingly provided on the corresponding side portion 63. The boss 81 can slide in the long groove 80 along the length direction. The long groove 80 and the boss 81 are respectively provided on both sides of the ADF cover 70, but since the two have the same structure, only one part is described here.
[0170] One end 82 of the long groove 80 engages with the boss 81 to keep the ADF cover 70 open, while the other end 83 of the long groove 80 engages with the boss 81 to keep the ADF cover 70 closed.
