DESCRIPTION OF EMBODIMENT

Hereinafter, the present disclosure will be schematically described first.

In order to solve the above problems, in an image reading apparatus according to a first aspect of the present disclosure includes a scanner unit configured to read a document, a document feed unit provided above the scanner unit and configured to feed the document and read the document, a first substrate configured to control an operation of the scanner unit, and a second substrate configured to control an operation of the document feed unit, wherein the first substrate and the second substrate are provided in a substrate placement section of the document feed unit.

According to this aspect, the first substrate and the second substrate are provided in the substrate placement section of the document feed unit. As a result, since both the first substrate for the scanner unit and the second substrate for the document feed unit are provided in the document feed unit, it is not necessary to secure a placement space for placing a control substrate in both of the scanner unit and the document feed unit, and it is possible to suppress an increase in the size of the apparatus.

In addition, when it becomes necessary to replace either or both of the first substrate and the second substrate, a replacement work may be performed only on the document feed unit, and thus the work is facilitated.

In the image reading apparatus according to a second aspect of the present disclosure is the image reading apparatus according to the first aspect wherein the first substrate is disposed so as to extend in a first direction, which intersects a horizontal direction.

According to this aspect, by disposing the first substrate in a direction, which intersects the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-rear direction or the left-right direction can be suppressed.

In the image reading apparatus according to a third aspect of the present disclosure is the image reading apparatus according to the first or second aspect wherein the second substrate is disposed so as to extend in a first direction, which intersects a horizontal direction.

According to this aspect, by disposing the second substrate in a direction, which intersects the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-rear direction or the left-right direction can be suppressed.

In the image reading apparatus according to a fourth aspect of the present disclosure is the image reading apparatus according to the first aspect wherein the first substrate and the second substrate are disposed so as to extend in a first direction, which intersects a horizontal direction, and overlap each other as viewed in the horizontal direction.

According to this aspect, by disposing both the first substrate and the second substrate in a direction, which intersects the horizontal direction, for example, vertically, it is possible to more effectively suppress an increase in the size of the apparatus in the horizontal direction, for example, the front-rear direction.

In addition, since the first substrate and the second substrate overlap each other as viewed in the horizontal direction, it is possible to suppress the size of the apparatus in the horizontal direction, for example, the left-right direction. In the image reading apparatus according to a fifth aspect of the present disclosure is the image reading apparatus according to the fourth aspect, wherein the first substrate is disposed in the document feed unit to outside with respect to the second substrate.

According to this aspect, when only the first substrate is to be removed for maintenance or the like, it is not necessary to remove the second substrate or a wiring connected to the second substrate, so that the work is easier.

In the image reading apparatus according to a sixth aspect of the present disclosure is the image reading apparatus according to the fourth aspect or the fifth aspect further include a wiring connecting the first substrate and the second substrate, wherein a non-overlapping region where the first substrate and the second substrate do not overlap each other as viewed in the horizontal direction overlaps the wiring as viewed in the horizontal direction.

Here, “overlaps with the wiring as viewed in the horizontal direction” in “non-overlapping region where the first substrate and the second substrate do not overlap each other as viewed in the horizontal direction overlaps the wiring as viewed in the horizontal direction” means that the wiring connecting the first substrate and the second substrate is disposed through the non-overlapping region.

According to this aspect, by using the non-overlapping region where the first substrate and the second substrate do not overlap each other as viewed in the horizontal direction as a placement space for the wiring, it is possible to suppress an increase in the size of the apparatus due to the protrusion of the wiring. Further, bypassing the wiring through the non-overlapping region, the length of the wiring can be shortened.

Further, if the wiring is concentrated around the substrate placement section at a rear of the apparatus, the wirings can be shortened and simplified. In addition, since a wiring work can be performed in one place, the work is facilitated.

In the image reading apparatus according to a seventh aspect of the present disclosure is the image reading apparatus according to any one of the fourth aspect to the sixth aspect further include a wiring connected to the first substrate or to the second substrate, whereinthe wiring is disposed in a region of the first substrate and the second substrate in the first direction.

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. Accordingly, since the wiring does not protrude upward or downward with respect to the substrate, the dimension in the height direction of the apparatus can be suppressed.

In the image reading apparatus according to an eighth aspect of the present disclosure is the image reading apparatus according to anyone of the first aspect to the seventh aspect further include a first holding section and a second holding section configured to hold the document feed unit so as to be pivotable with respect to the scanner unit, wherein the substrate placement section is provided between the first holding section and the second holding section.

Here, “between the first holding section and the second holding section” in “the substrate placement section is provided between the first holding section and the second holding section” does not need to be completely contained therebetween, for example, means that the substrate placement section may be disposed between respective outer end sections of the first holding section and the second holding section in the left-right direction.

According to this aspect, since the first substrate and the second substrate provided in the substrate placement section are provided between the first holding section and the second holding section, the size in the left-right direction can be suppressed.

Here, “between the holding section and the drive section” in “the substrate placement section is provided between the holding section and the drive section” does not needs to be completely contained therebetween, for example, means that the substrate placement section may be disposed between respective outer end sections of the holding section and the driving section in the left-right direction and the front-rear direction.

According to this aspect, since the first substrate and the second substrate provided in the substrate placement section are provided between the holding section and the drive section, the size in the left-right direction and the front-rear direction can be suppressed.

In addition, in any one of the first aspect to the ninth aspect, the scanner unit may include a cable configured to transmit data obtained by reading the document to the first substrate, and the substrate placement section may be disposed so as to overlap the cable as viewed in the horizontal direction.

With this arrangement, since the cable, which is, for example, an FFC or the like used for receiving data obtained by reading the second surface, and the substrate placement section overlap with each other, the size of the apparatus becoming large due to the cable can be suppressed.

Further, when the cable and the wiring are concentrated at the rear of the apparatus, the length of the cable and the wiring can be shortened, and the structure becomes simple. In addition, since the wiring work can be performed in one place, the work is facilitated.

In the image reading apparatus according to a tenth aspect of the present disclosure is the image reading apparatus according to any one of the first aspect to the ninth aspect wherein at least one of the first substrate and the second substrate is removably attached in the substrate placement section by an attachment member and the attachment member is inserted and extracted along a first direction, which intersects a horizontal direction.

According to this aspect, since the attachment direction of at least one of the first substrate and the second substrate via the attachment members is same as the insertion and extraction direction of the attachment member, it become easy to perform a work for attachment and detachment and it becomes easy to secure the work space.

In a recording apparatus according to an eleventh aspect of the present disclosure includes the image reading apparatus according to any one of the first aspect to the tenth aspect further include a recording unit configured to execute recording process based on data read by the image reading apparatus.

According to this aspect, the recording unit includes the control substrate configured to control the entire apparatus, and the control substrate overlaps with the substrate placement section as viewed in the first direction, which intersects the horizontal direction. Accordingly, since the control substrate overlaps with the substrate placement section, the size of the apparatus can be effectively suppressed.

Embodiment

Hereinafter, an image reading apparatus according to an embodiment of the present disclosure and a recording apparatus including the image reading apparatus will be specifically described with reference toFIGS.1to12.

In the following description, three axes orthogonal to each other are referred to as an X-axis, a Y-axis, and a Z-axis, as shown in the drawings. The Z-axis direction corresponds to the vertical direction (a direction in which gravity acts). The X-axis direction and the Y-axis direction correspond to a horizontal direction.

As shown inFIG.5, a recording apparatus100of the present embodiment includes an image reading apparatus1and a recording unit3capable of executing a recording process based on data read by the image reading apparatus1.

In the present embodiment, the recording unit3is an ink jet printer that performs recording by using a transport roller to transport a medium (not shown), such as printing paper or the like, accommodated in a medium cassette or the like to a recording execution section that performs recording by a recording head or the like and ejecting ink there, and that is capable of executing recording based on data read by the image reading apparatus1.

As shown inFIG.5, the image reading apparatus1includes a scanner unit9configured to read a document5, and an ADF unit13provided above the scanner unit9and configured to feed and read the document5. The ADF unit13is an auto document feeder, and is an example of a document feed unit.

Further, as shown inFIGS.2and4, a first substrate15configured to control the operation of the scanner unit9, and a second substrate17configured to control the operation of the ADF unit13are provided. Both the first substrate15and the second substrate17are provided in a substrate placement section19of the ADF unit13. The substrate placement section19is located at a rear section14in a front-rear direction of the ADF unit13.

As shown inFIGS.1and2, the ADF unit13is pivotably attached to the scanner unit9located below by a pair of left and right hinges, that is, a first holding section2and a second holding section4located in the rear section14. That is, the ADF unit13is attached to the scanner unit9, and can be opened and closed with a front section16thereof as a free end.

Hereinafter, each component will be described in detail.

Scanner Unit

In the scanner unit9according to the present embodiment, by placing the ADF unit13into an “open” state with respect to the scanner unit9, and placing a document5on a transparent document placing plate (not shown), reading is executed on the document5by a scanner reading section (not shown), such as a line image sensor disposed below the document placing plate. The scanner reading section moves along a reading surface of the document5in a width direction (X-axis direction) of the apparatus when executing reading.

It should be noted that illustration of a state in which the document5being read by the scanner reading section while the document5is placed on the document placing plate is omitted because it is within a scope of public knowledge.

ADF Unit

As shown inFIGS.1and5, in a state in which the ADF unit13is “closed” with respect to the scanner unit9, the document5set on the feed tray6is fed along a feed path by the feed section. The feed section includes a known pickup roller (not shown) and a feed roller8(FIG.4). The feed path has a U-shaped inversion section10, and the document5fed along the feed path is discharged onto a discharge tray12. The discharge tray12is positioned above the document placing plate of the scanner unit9.

While the document5is fed through the U-shaped inversion section10, the document5is read by an ADF reading section (not shown) such as the line image sensor. The ADF reading section is disposed so as to read an image of a second surface11, which is a surface of the document5set on the feed tray6and which is in contact with the feed tray6.

It should be noted that an illustration of a state in which the document5fed by the feed section is being read by the ADF reading section is omitted because it is within the scope of public knowledge.

In the present embodiment, the ADF unit13is removably provided to a rear cover22at the rear section14thereof. When the rear cover22is removed, the substrate placement section19covered from above by an upper cover24(FIG.3) made of a flame retardant material appears. The upper cover24is also removable, and by removing the upper cover24, the substrate placement section19is exposed, so that the replacement work or the like of the first substrate15and the second substrate17can be performed.

A state in which the rear cover22is removed from a state inFIG.1is a state inFIG.3, and a state in which the upper cover24is removed from the state inFIG.3is a state inFIG.2.

The upper cover24is removably attached to an attachment section of the ADF unit13by two screws30. The rear cover22is also removably attached to the attachment section of the ADF unit13by a plurality of screws (not shown).

When Images are Formed on Both Front and Back Surfaces of the Document

The image reading apparatus1of the present embodiment is configured such that, when images are formed on both front and back surfaces of the document5, images on both surfaces can be read at once. That is, while the document5set on the feed tray6is fed by a feed mechanism along the feed path having the U-shaped inversion section10, the document5passes between the ADF reading section and the scanner reading section. During this passing, the scanner reading section does not move and is maintained in a stopped state. Thus, images on both sides of the document5can be read at once by using the ADF reading section and the scanner reading section.

Specifically, inFIG.5, the second surface11of the document5set on the feed tray6is read by the ADF reading section, and a first surface7, which is the opposite of the document5from the second surface11, is read by the scanner reading section which is in the stopped state.

Substrate Placement Section, First Substrate, and Second Substrate

In this embodiment, as described above, the substrate placement section19is located in the rear section14of the ADF unit13. The first substrate15is disposed so as to extend in a direction, which intersects the horizontal direction. The second substrate17is also disposed so as to extend in a direction, which intersects the horizontal direction. That is, both the first substrate15and the second substrate17are disposed in the substrate placement section19so as to extend in a first direction, which intersects the horizontal direction.

Specifically, as shown inFIGS.2and4, the first substrate15and the second substrate17are disposed vertical in the substrate placement section19. The first substrate15and the second substrate17are disposed in a positional relationship in which they overlap each other as viewed in the horizontal direction. Here, the substrate placement section19is a region including both a region a first region18occupied by disposing the first substrate15there and a second region20occupied by disposing the second substrate17there.

It should be noted that “vertical” does not necessitate vertical, that is, straight upright in a strict sense, and may be inclined within a range in which an effect of the present disclosure can be obtained. In addition, “parallel” does not necessitate being parallel in a strict sense, that is, may be shifted from parallel within a range in which an effect of the present disclosure can be obtained.

Furthermore, in this embodiment, as can be understood fromFIGS.2and4, the first substrate15is disposed to the outside of the second substrate17. Here, by disposing the first substrate15directly above a wiring outlet28of the scanner unit9, it is possible to suppress the likelihood that the wiring route of the scanner unit9will become complicated.

Wiring

Further, as shown inFIGS.6and7, in the present embodiment, a wiring21for connecting the first substrate15and the second substrate17is provided. Then, a non-overlapping region23, in which the first substrate15and the second substrate17do not overlap each other as viewed in the horizontal direction, is provided so as to overlap the wiring21as viewed in the horizontal direction. Here, as can be understood fromFIGS.6and7, the “non-overlapping region23as viewed in the horizontal direction” is a region that occurs by the first substrate15and the second substrate17being shifted from each other in the width direction (X-axis direction) of the apparatus.

Signals can be exchanged between the first substrate15and the second substrate17by the wiring21. For example, when images on both sides of the document5are read at once using the ADF reading section and the scanner reading section, data read by the scanner reading section is transmitted from the first substrate15to the second substrate7via the wiring21. The scanner reading section and the second substrate17may be directly connected by wiring so that the read data is directly transmitted to the second substrate17.

Here, “overlap the wiring21as viewed in the horizontal direction” means that the wiring21connecting the first substrate15and the second substrate17is disposed through the non-overlapping region23.

The wiring21is a wiring that connects the first substrate15and the second substrate17, but is not limited thereto.

In other words, inFIG.6, the wiring21extends so as to intersect with a line extending from the first substrate15, which is provided to the outside of the second substrate17.

Therefore, when there is no “non-overlapping region as viewed in the horizontal direction” of the first substrate15and the second substrate17, the wiring21bypasses around the outside of the substrate placement section19, and there is a concern that the size of the device will increase because of wiring space.

On the other hand, in the present embodiment, since the wiring21, which extends so as to intersect with a line extending from the first substrate15, is provided so as to overlap the “non-overlapping region as viewed in the horizontal direction” of the first substrate15and the second substrate17, it is possible to suppress an increase in size of the device due to wiring space.

Further, as shown inFIGS.6and7, wirings25,27, and29connected to the first substrate15or the second substrate17are provided in addition to the wiring21. The wirings25,27, and29are connected to various sensors or to actuators or the like such as motors or the like. The wiring21and the wirings25,27, and29are provided so as to be disposed within a region in the first direction, that is, the described above “vertical” direction, within which the first substrate15and the second substrate17are located. In other words, the wiring21and the wirings25,27, and29are disposed so as to be routed in the left-right direction (X-axis direction) and the depth direction (Y-axis direction), but are not disposed vertically above or below the first substrate15and the second substrate7, that is, they do no project higher or lower in the vertical direction (Z-axis direction) than does the first substrate15or the second substrate7.

In the first substrate15and the second substrate17, portions where the wiring21and the wirings25,27, and29are connected have connectors that enable the wiring21and the wirings25,27, and29to be routed in the left-right direction (X-axis direction) and the depth direction (Y-axis direction). Further, by removing the wiring21and the wirings25,27, and29from the connectors, the first substrate15and the second substrate17are separated from the respective wirings to be in a free state, and can be easily removed from the ADF unit13.

Further, the wiring21and the wirings25,27, and29are concentrated in a rear section of the ADF unit13.

Although a part of the wirings25,27, and29are not shown in the drawing in order to avoid complication of the drawing, the wirings25,27, and29are also arranged so as not to project in the vertical direction (Z-axis direction) from the first substrate15and the second substrate7.

Here, the wiring25indicates a wiring that extends from the first substrate15and is connected to a drive mechanism section (not shown) of the scanner unit9. The wiring25passes through a wiring outlet26and is introduced from inside of the ADF unit13into inside of the scanner unit9.

The wiring27indicates a wiring that extends from the second substrate17and is connected to a drive section31(FIG.2) of the ADF unit13. The second substrate17is positioned on the right side of the drive section31.

The wiring29indicates a wiring that extends from the first substrate15and is connected to a main substrate35(FIG.5) of the recording unit3. The main substrate35is an example of a control substrate configured to control the entire apparatus. The wiring29passes through the wiring outlet28and is introduced from inside of the ADF unit13into the inside of recording unit3.

As shown inFIG.5, the wiring29introduced into the recording unit3is connected to the main substrate35, which controls the entire apparatus included in the recording unit3. By this, the recording unit3can execute recording based on the data read by the image reading apparatus1.

In the present embodiment, the main substrate35is disposed so as to overlap with the substrate placement section19as viewed in the first direction, that is, as viewed in the vertical direction.

Specifically, the main substrate35is disposed at a rear section of the recording unit3in the front-rear direction. The main substrate35is disposed “vertical” at a position in substantially the same rear section as the first substrate15in a region below the wiring outlet28. In other words, the plane formed by the main substrate35and the plane formed by the first substrate15are disposed in a state in which they can be regarded as substantially one plane. Here, “a state in which they can be regarded as substantially one plane” means that one of the planes may protrude as long as the planes overlap each other.

Cable of Scanner Unit

As shown inFIG.7, in the present embodiment, the scanner unit9includes a cable37for transmitting data obtained by reading the document5by the scanner reading section (not shown) to the first substrate15. The cable37is formed by an FFC. The substrate placement section19is disposed so as to overlap with the cable37as viewed in the horizontal direction. By this, since the cable37is disposed at a position within a width direction of the substrate placement section19, the required length of the cable37can be shortened.

In addition, since the cable37can be connected by being drawn out directly upward without being routed left or right, the length can be more effectively suppressed.

The cable37is configured to be removed from a connection portion of the first substrate15. By removing the cable37from the connection portion of the first substrate15, the first substrate15is separated from the cable37to be in a free state, and can be easily removed from the ADF unit13.

As shown inFIG.7, in the present embodiment, the first substrate15and the second substrate17are removably attached to the substrate placement section19by an attachment member39and an attachment member41, respectively. The attachment members39and41are configured to be inserted and extracted along the first direction, which intersects the horizontal direction, that is, in the vertical direction. Here, the attachment members39and41are configured by shield plates made from sheet metal, and have a shape and a structure capable of holding the first substrate15and the second substrate17, which are the targets to be held.

More specifically, the attachment member39is attached to the attachment section of the ADF unit13by two screws32, and the attachment member41is attached to the attachment section of the ADF unit13by three screws34. By removing these screws32and34, the attachment members39and41can be drawn upward.

Further, as shown inFIG.8, the first substrate15is removably attached to the attachment member39by six screws36. By removing all of the screws36, the first substrate15can be removed from the attachment member39.

As shown inFIG.9, the second substrate17is removably attached to an attachment member41by six screws38. By removing all of the screws38, the second substrate17can be removed from the attachment member41.FIG.9is a view in which the first substrate15is removed fromFIG.8so that entire of the second substrate17can be seen.

As shown inFIG.2, the first holding section2and the second holding section4, which pivotably hold the ADF unit13with respect to the scanner unit9, are provided on left and right sides of the rear section14of the apparatus as described above. The substrate placement section19is provided between the first holding section2and the second holding section4in the left-right direction (X-axis direction).

Further, the ADF unit13includes a feed section constituted by feed roller8or the like for feed of the document5, and the drive section31for drive of the feed section. The substrate placement section19is provided between the holding sections2and4and the drive section31in the depth direction (Y-axis direction).

As shown inFIGS.6,7, and10, the wiring29is guided by a guide section43, and the guide section43is provided so as to be pivotably with respect to the ADF unit13. The wiring29is guided from the inside to the outside of the ADF unit13through the inside of the guide section43.

The guide section43is pivotably attached to an attachment section42of the ADF unit13by a shaft40. In this state, the guide section43is inserted into an attachment section44(FIG.7) of the scanner unit9. As a result, the ADF unit13is able to pivot about the shaft40relative to the scanner unit9.

Replacement Work of First Substrate and Second Substrate

First, the rear cover22(FIG.1) located at the rear section14of the ADF unit13is removed, and then the upper cover24(FIG.3) is also removed. As a result, the substrate placement section19is exposed, and replacement work or the like of the first substrate15and the second substrate17can be performed (FIGS.2and7).

Subsequently, by removing the two screws32, the attachment member39, to which is attached the first substrate15located outside the rear section14, can be pulled out upward. The first substrate15can be removed from the attachment member39by removing the six screws36(FIG.8) in a state in which the attachment member39is pulled out. At this time, the first substrate15is brought into a free state by removing the wiring21and the wirings25,27, and29from the connection portions of the first substrate15.

Then, the first substrate15, which is the target of exchange, is removed and replaced with a new first substrate15, and the procedure in the reverse order from that of the above is performed to complete the replacement work.

In the replacement work of the second substrate17, by removing the three screws34in the state ofFIG.7, the attachment member41, to which the second substrate17is attached, can be pulled out upward. The second substrate17can be removed from the attachment member41by removing the six screws38(FIG.9) in a state in which the attachment member41is pulled out. At this time, the second substrate17is brought into a free state by removing the wiring21and the wirings25,27, and29from the connection portions of the second substrate17.

Then, the second substrate17, which is the target of exchange, is removed and replaced with a new second substrate17, and the procedure is the reverse order from that of the above is performed to complete the replacement work.

Description of Effects of Embodiment

(1) According to the present embodiment, the first substrate15and the second substrate17are provided in the substrate placement section19of the ADF unit13. Thus, since both the first substrate15for the scanner unit9and the second substrate17for the ADF unit13are provided in the ADF unit13, it is not necessary to secure a placement space for placing a control substrate in both of the scanner unit9and the ADF unit13, and it is possible to suppress an increase in the size of the apparatus.

Further, when it becomes necessary to replace either or both of the first substrate15and the second substrate17, the replacement work may be performed only on the ADF unit13, and thus the work is facilitated.

(2) In addition, according to the present embodiment, by disposing the first substrate15in a direction, which intersects the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-rear direction or the left-right direction can be suppressed.

(3) In addition, according to the present embodiment, by disposing the second substrate17in a direction, which intersects the horizontal direction, for example, vertically, the size in the horizontal direction, that is, the size in the front-rear direction or the left-right direction can be suppressed.

(4) Further, according to the present embodiment, by arranging both the first substrate15and the second substrate17in a direction, which intersects the horizontal direction, for example, vertically, it is possible to more effectively suppress an increase in the size of the apparatus in the horizontal direction, for example, the front-rear direction.

Furthermore, since the first substrate15and the second substrate17overlap each other as viewed in the horizontal direction, it is possible to suppress the size of the apparatus in the horizontal direction, for example, the left-right direction.

(5) In addition, according to this embodiment, since the first substrate15is disposed to be outside with respect to the second substrate17, when only the first substrate15is to be removed for maintenance or the like, it is not necessary to remove the second substrate17or the wirings25,27, and29connected to the second substrate. Therefore, the work is easier.

Further, by disposing the first substrate15directly above the wiring outlets26and28of the scanner unit9, it is possible to suppress the wiring route of the scanner unit9from becoming complicated.

(6) In addition, according to the present embodiment, by using the non-overlapping region23, where the first substrate15and the second substrate17do not overlap each other as viewed in the horizontal direction, as a placement space for the wiring21that connects the first substrate15and the second substrate17, it is possible to suppress an increase in the size of the apparatus due to the protrusion of the wiring21.

If the wirings21,25,27, and29are concentrated in the rear section14, which is the rear section of the apparatus, these wirings can be shortened and simplified. In addition, since a wiring work can be performed in one place, the work is facilitated.

(7) According to the present embodiment, the wirings21,25,27, and29connected to the first substrate15or to the second substrate17are disposed in a region of the first substrates15and second substrates17in the first direction (Z-axis direction). As a result, since the wirings21,25,27, and29do not protrude upward or downward with respect to the first substrates15and second substrates17, the dimension in the height direction of the apparatus can be suppressed.

(8) According to the present embodiment, since the first substrate15and the second substrate17provided in the substrate placement section19are provided between the first holding section2and the second holding section4, the size in the left-right direction can be suppressed.

(9) According to the present embodiment, since the first substrate15and the second substrate17provided in the substrate placement section19are provided between the holding sections2and4and the drive section31, the size in the left-right direction and the front-rear direction can be suppressed.

(10) According to the present embodiment, since the cable37, which is, for example, an FFC or the like used for receiving data obtained by reading the second surface11, and the substrate placement section19overlap with each other, the size of the apparatus becoming large due to the cable37can be suppressed.

Further, when the cable37and the wirings21,25,27, and29are concentrated in the rear section14of the apparatus, the lengths of the cable37and the wirings21,25,27, and29can be shortened, and the structure becomes simple. In addition, since the wiring work can be performed in one place, the work is facilitated.

(11) According to the embodiment, the first substrate15and the second substrate17are removably attached in the substrate placement section19by the attachment members39and41, and the attachment members39and41are inserted and extracted along the first direction, which intersects the horizontal direction. As a result, since the attachment direction of the first substrate15and the second substrate17via the attachment members39and41is same as the insertion and extraction direction of the attachment members39and41, it become easy to perform the work for attachment and it becomes easy to secure the work space.

(12) The recording apparatus100according to the present embodiment includes the image reading apparatus1and the recording unit3configured to execute recording process based on data read by the image reading apparatus1. By this, it is possible to suppress an increase in size in the recording apparatus100configured to record a reading result of the image reading apparatus1on a medium.

(13) According to the embodiment, the recording unit3includes the main substrate35configured to control the entire apparatus, and the main substrate35is connected to the first substrate15or the second substrate17by the wiring29. Thus, information can be exchanged between the image reading apparatus1and the recording unit3.

(14) According to the present embodiment, the wiring29is guided by the guide section43, and the guide section43is provided so as to be pivotable with respect to the ADF unit13. Thus, the wiring29can be guided with a simple configuration, and the appearance can also be improved.

(15) In addition, according to the embodiment, the recording unit3includes the main substrate35configured to control the entire apparatus, and the main substrate35overlaps with the substrate placement section19as viewed in the first direction (the Z-axis direction), which intersects the horizontal direction. Since the main substrate35overlaps the substrate placement section19in this manner, the size of the apparatus can be effectively suppressed.

Attachment Structure of Cosmetic Line of Scanner Unit (FIGS.11and12)

As shown inFIG.11, sometimes a cosmetic line51is provided in a part of an upper case50forming a part of a case of the scanner unit9. A lower case52is attached to a lower section of the uppercase50by a plurality of screws57. Since the cosmetic line51is provided from the viewpoint of design or the like, a color different from that of the upper case50and the lower case52is used. For example, the upper case50is white, the cosmetic line51is blue, and the lower case52is black, or the like.

As shown inFIG.12, a groove53is formed along an edge of an upper surface of the upper case50. The inside of the groove53is isolated from the inside of the scanner unit9, so that liquid such as water or the like and small foreign matter entering the groove53do not enter the inside of the scanner unit9.

On the other hand, the cosmetic line51is provided with a downward-projecting convex section54at the upper section of a main body56. The cosmetic line51is assembled to the upper case50by fitting the convex section54into the groove53. As shown inFIG.12, an L-shaped piece55protrudes from the inner surface of the lower section of the main body56of the cosmetic line51. A plurality of the L-shaped pieces55are provided at intervals in the longitudinal direction of the cosmetic line51.

The lower case52is provided with an insertion section58to be inserted into a U-shaped recess section59between the L-shaped piece55of the cosmetic line51and the main body56.

By inserting the insertion section58of the lower case52into the U-shaped recess section59of the cosmetic line51in a state in which the convex section54of the cosmetic line51is fitted into the groove53of the upper case50, the assembly of the upper case50, the cosmetic line51, and the lower case52is completed. In this state, the upper case50and the lower case52are fixed to each other by the screws57. Although the cosmetic line51is not directly fixed by the screw57, the cosmetic line51is attached as described above so as not to be unintentionally removed.

Frame Structure Forming Feed Path of ADF Unit (FIGS.13and14)

As shown inFIG.13, a main frame60forming a feed path for feed of the document5in the ADF unit13is formed of a resin material. The main frame60includes a feed support surface section61configured to support the document5, and a side surface section62and a side surface section63that are located on both sides, and has a substantially H-shape as a whole. The main frame60, which is made entirely from a resin material, has a lower deformation resistance against external forces than would a main frame made by a sheet metal, and is easily twisted, for example. Therefore, here, a reinforcement frame64and a reinforcement frame65made from sheet metal are integrally joined to the side surface sections62and63to enhance deformation resistance.

Specifically, the reinforcement frame64is fixed to the side surface section62by a plurality of screws66in a surface contact state.

On the other hand, the reinforcement frame65is fixed to the side surface section63by screws68via a cushioning material67such as a rubber material or the like. As shown in the partially enlarged sectional view ofFIG.14, the reinforcement frame65has a gap69between the reinforcement frame65and the side surface section63. Since a driving section such as a motor or the like is attached to the side surface section63, vibration is generated. The cushioning material67and the gap69suppress vibration from being transmitted to the main frame60. On the other hand, since the drive section such as the motor or the like is not attached to the side surface section62, the above-described cushioning material is not provided.

Structure for Holding Open State of ADF Cover (FIGS.15to17)

In the ADF unit13, a paper stoppage, that is, a jam may occur when the document5is fed. In order to resolve the jam, the ADF cover70is configured to be opened and closed by pivoting in the vertical direction.FIG.15shows a state in which the ADF cover70is closed, andFIG.16shows a state in which the ADF cover70is opened.

As shown inFIG.15, the ADF cover70includes a lock stacker71on a side surface below a pivotal fulcrum (not shown). One lock stacker71is provided on one side of the ADF cover70. Note that one each may be provided on both sides. In this case, it is desirable that both on both sides have the same structure. The lock stacker71is configured such that a spring force is applied in a direction in which a semi-spherical section72protrudes outward, and stops at a position of a predetermined amount of protrusion.

In a state in which the ADF cover70is closed, as shown inFIG.15, the semi-spherical section72of the lock stacker71is located at an external position not facing the side surface section63of the main frame60. On the other hand, as shown inFIG.16, when the ADF cover70pivots about the pivotal fulcrum and shifts to the opened state, the portion of the lock stacker71moves to an internal position facing the side surface section63of the main frame60and cannot be seen from the outside.

As shown in the partially enlarged sectional perspective view inFIG.16, when the ADF cover70reaches the endpoint position of the opened state, the semi-spherical section72of the lock stacker71enters a hole73provided at a position corresponding to the side surface section63by the spring force and enters the locked state. As a result, the ADF cover70is held in the opened state. When the ADF cover70is pivoted in the closing direction, the semi-spherical section72is pushed back against the spring force, slides on the opposing surface of the side surface section63, and reaches the end point position of the closed state (FIG.15). In the drawings, reference numeral74denotes the lock stacker71, and reference numeral75denotes a spring that applies the spring force.

FIG.17is another example of the structure for holding open state of ADF cover. In this example, an elongate groove80having a curved shape is formed on a side surface of the ADF cover70, and a boss81protrudes from a corresponding side surface section63. The boss81is configured to slide in the elongate groove80in the longitudinal direction. The elongate groove80and the boss81are provided on both sides of the ADF cover70, but since those on both sides have the same structure, only those on one side will be described here.

One end section82of the elongate groove80locks with the boss81to hold the ADF cover70in the opened state. The other end section83of the elongate groove80locks with the boss81to hold the ADF cover70is closed state.

ANOTHER EMBODIMENT

The image reading apparatus1and the recording apparatus100according to the present disclosure basically have the configurations of the above-described embodiments, but it is needless to say that partial configuration changes, omissions, and the like can be made without departing from the scope of the present disclosure.

In the above embodiment, both of the first substrate15and the second substrate17are arranged vertical, but only one of the substrates may be disposed vertical.

Further, “vertical” is desirably straight upright, but it is not limited to straight upright, and may be inclined.

Although the case where the first substrate15is arranged to the outside with respect to the second substrate17was described in the above embodiment, the second substrate17may be arranged to the outside with respect to the first substrate15. In this case, the main substrate35is connected to the second substrate17.
