[0029] The present invention will now be described in summary.

[0031] According to this method, the head control unit is mounted on the frame. Thus, by mounting the head control unit on the frame, the cable wiring within the device can be shortened. Therefore, noise generation can be suppressed, and cost increases can be mitigated.

[0032] The recording device according to the second aspect of the present invention is a subordinate aspect of the first aspect, characterized in that the surfaces of the first substrate and the second substrate extend in a direction intersecting the frame.

[0033] According to this method, the surfaces of the first substrate and the second substrate extend in a direction intersecting the frame. By configuring it in this way, both surfaces of the first substrate and the second substrate are easily visible and become easily accessible to the user.

[0034] The recording device involved in the third aspect of the present invention is a method subordinate to the first or second aspect, characterized in that the first substrate and the second substrate are connected by a substrate-to-substrate connector.

[0035] According to this method, the first substrate and the second substrate are connected via a substrate-to-substrate connector. This structure allows for easy connection of the first and second substrates, and enables communication or power supply between them. Furthermore, it suppresses the distance between the first and second substrates and prevents the device from becoming too large.

[0036] The recording apparatus according to the fourth aspect of the present invention is a subordinate aspect of the third aspect, characterized in that the length of the electrical component disposed between the first substrate and the second substrate and mounted on the first substrate or the second substrate in the opposing direction is less than the length of the substrate-to-substrate connector in the opposing direction.

[0037] According to this method, the length of the electrical component disposed between the first substrate and the second substrate in the opposing direction is less than the length of the substrate-to-substrate connector in the opposing direction. By configuring the structure in this way, the length between the first substrate and the second substrate can be suppressed even when the electrical component is disposed between the first substrate and the second substrate.

[0038] The recording device involved in the fifth aspect of the present invention is a method belonging to any one of the first to fourth aspects, characterized in that the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, and a connector is provided in the first region.

[0039] According to this method, the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, and a connector is provided in the first region. Thus, by providing the connector in the region on the first substrate that does not overlap with the second substrate, connecting the cable to the connector is facilitated.

[0040] The recording apparatus according to the sixth aspect of the present invention is a subordinate aspect of the fifth aspect, characterized in that the first substrate has the first region at an end along a first direction of the first substrate, and at least a portion of the ends of the first substrate and the second substrate in a second direction opposite to the first direction are aligned.

[0041] According to this method, the first substrate has a first region at its end in a first direction, and at least a portion of the ends of the first substrate and the second substrate in a second direction are aligned. By configuring it in this way, the area occupied by the first substrate and the second substrate within the device can be suppressed, thereby suppressing the enlargement of the device.

[0042] The recording device according to the seventh aspect of the present invention is any one of the first to third aspects, characterized in that the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, the second substrate has a second region that does not overlap with the first substrate when viewed along the opposing direction, and connectors are provided in the first region and the second region.

[0043] According to this method, the first substrate has a first region that does not overlap with the second substrate when viewed in the opposing direction, and the second substrate has a second region that does not overlap with the first substrate when viewed in the opposing direction. Connectors are provided in both the first and second regions. Thus, by providing connectors in the regions on the first substrate that do not overlap with the second substrate, connecting cables to connectors is facilitated.

[0044] The recording device according to the eighth aspect of the present invention is any one of the first to seventh aspects, characterized in that the first substrate and the second substrate each have a first surface on which an electrical component is mounted and a second surface opposite to the first surface, the second surface of the first substrate faces the first surface of the second substrate, the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, and a connector for connecting the first cable is provided on the second surface of the first region.

[0045] According to this method, both the first substrate and the second substrate have a first surface and a second surface on which electrical components are mounted. The second surface of the first substrate faces the first surface of the second substrate. The first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction. A connector for connecting a first cable is provided on the second surface of the first region. By configuring it in this way, the first substrate of the recording unit and the head control unit can be connected. Furthermore, by providing the connector in the region where the first substrate and the second substrate do not overlap (face each other), the connection of the cable to the connector is facilitated.

[0046] The recording device according to the ninth aspect of the present invention is a type subordinate to the eighth aspect, characterized in that the second substrate has a second region that overlaps with the first substrate when viewed along the opposing direction, and a connector for connecting the first cable is provided on the second surface of the second region.

[0047] According to this method, the second substrate has a second region that overlaps with the first substrate when viewed in an opposing direction, and a connector for connecting a first cable is provided on the second surface of the second region. This structure allows for the connection of the second substrate to the recording unit and the head control unit. Since the connector is provided on the second surface of the second substrate facing the side opposite to the first substrate, connecting the first cable is easy even if the connector is provided in the second region of the second substrate that overlaps with the first substrate.

[0048] The recording device involved in the tenth aspect of the present invention is a type subordinate to the eighth or ninth aspect, characterized in that the first cable is a flexible flat cable.

[0049] According to this method, the first cable is a flexible flat cable. Although the information transmission between the recording unit and the head control unit has a significant impact on recording accuracy, using a flexible flat cable to connect the two provides strong noise resistance. Furthermore, this structure shortens the first cable, thereby further enhancing noise resistance.

[0050] The recording device according to the eleventh aspect of the present invention is a type subordinate to the eighth or ninth aspect, characterized in that the first cable has a connecting substrate connected to the first substrate, and the first substrate and the connecting substrate are connected by a substrate-to-substrate connector.

[0051] According to this method, the first cable has a connecting substrate connected to the first substrate, and the first substrate and the connecting substrate are connected by a substrate-to-substrate connector. This structure improves maintainability.

[0052] The recording apparatus according to the twelfth aspect of the present invention is a type belonging to any one of the first to eleventh aspects, characterized in that it comprises: a main body control unit that controls the main body of the apparatus; a second cable that electrically connects the head control unit and the main body control unit; both the first substrate and the second substrate have a first surface on which an electrical component is mounted and a second surface that is opposite to the first surface; the second surface of the first substrate faces the first surface of the second substrate; the second substrate has a third region that does not overlap with the first substrate when viewed along the opposing direction; and a connector for the second cable is provided on the first surface of the third region.

[0053] According to this method, the second surface of the first substrate faces the first surface of the second substrate. The second substrate has a third region that does not overlap with the first substrate when viewed along the opposing direction. A connector for connecting a second cable is provided on the first surface of the third region, and the second cable is electrically connected to the head control unit and the main body control unit. This structure allows the second substrate and the main body control unit to be connected together. Furthermore, by providing the connector in the region on the second substrate that does not overlap with the first substrate, connecting the second cable to the connector is facilitated.

[0054] The recording device involved in the thirteenth aspect of the present invention is a subordinate aspect to the twelfth aspect, characterized in that the second cable is a USB (Universal Serial Bus) communication cable.

[0055] According to this method, the second cable is a USB communication cable. Although the information transmission between the second substrate and the recording unit has a significant impact on recording accuracy, the communication between the first substrate and the second substrate has a smaller impact on recording accuracy. Therefore, by using a USB communication cable to connect the first substrate and the second substrate, costs can be suppressed without reducing recording accuracy.

[0056] The recording device according to the fourteenth aspect of the present invention is any one of the first to thirteenth aspects, characterized in that it includes a third cable that supplies power to the head control unit, the first substrate and the second substrate each have a first surface on which an electrical component is mounted and a second surface opposite to the first surface, the second surface of the first substrate faces the first surface of the second substrate, the second substrate has a second region that overlaps with the first substrate when viewed along the opposing direction, and a connector for connecting to the third cable is provided on the second surface of the second region.

[0057] According to this method, the second substrate has a second region that overlaps with the first substrate when viewed in an opposing direction. A connector for connecting to a third cable is provided on the second surface of the second region, and the third cable supplies power to the head control unit. This structure enables power supply. Furthermore, since the connector is provided on the second surface of the second substrate facing the side opposite to the first substrate, connecting the third cable is easy even if the connector is provided in the area overlapping with the first substrate.

[0058] The recording apparatus according to the fifteenth aspect of the present invention is a method belonging to any one of the first to fourteenth aspects, characterized in that both the first substrate and the second substrate have a first surface on which an electrical component is mounted and a second surface as a surface opposite to the first surface, and the second surface of the first substrate faces the second surface of the second substrate.

[0059] According to this method, both the first substrate and the second substrate have a first surface and a second surface on which electrical components are mounted, with the second surface of the first substrate facing each other. Thus, by positioning the first surface on both the first and second substrates so that it is the outermost surface, the possibility of the distance between the first and second substrates increasing can be suppressed.

[0060] The recording apparatus according to the sixteenth aspect of the present invention is a type belonging to any one of the first to fifteenth aspects, characterized in that it includes a substrate mounting part, which is mounted on the frame and has the first substrate and the second substrate mounted thereon, and a third substrate can be mounted on the substrate mounting part in place of the first substrate.

[0061] According to this method, a substrate assembly section is provided, which is mounted on a frame and has a first substrate and a second substrate mounted thereon. A third substrate can be mounted on the substrate assembly section in place of the first substrate. By providing such a structure, substrate replacement becomes easy.

[0062] The recording apparatus according to the seventeenth aspect of the present invention is a type belonging to any one of the first to sixteenth aspects, characterized in that it includes a cooling section, which is mounted on the frame and cools the head control section. The head control section has a housing section for housing the first substrate and the second substrate, and the cooling section cools the interior of the housing section.

[0063] According to this method, a cooling section is provided that is mounted on a frame and cools the head control unit. The head control unit has a housing section that houses the first substrate and the second substrate, and the cooling section cools the interior of the housing section. By providing such a structure, the head control unit can be cooled. Furthermore, since the cooling section and the head control unit are mounted on the same frame, the cooling efficiency can be improved compared to the case where the cooling section and the head control unit are in separate positions.

[0064] The recording device according to the eighteenth aspect of the present invention is a subordinate aspect of the seventeenth aspect, characterized in that the cooling section has: an air inlet section; an exhaust section; and a pipe for gas to flow between the air inlet section and the exhaust section, wherein the air inlet section is located below the receiving section and the exhaust section is located above the receiving section.

[0065] According to this method, the air inlet of the cooling unit is located lower than the housing, and the exhaust unit is located higher than the housing. By setting the structure in this way, and by inletting air from below and exhausting it from above, the gas can be circulated while utilizing the rising airflow, thus enabling efficient cooling of the head control unit.

[0066] The recording apparatus according to the nineteenth aspect of the present invention is a type subordinate to the sixth aspect, characterized in that it includes a cooling section mounted on the frame and used to cool the head control section. The head control section has a housing section for housing the first substrate and the second substrate. The cooling section includes: an air inlet section; an air outlet section; and a conduit for supplying gas to flow from the air inlet section through the housing section to the air outlet section. The conduit allows gas to flow into the housing section from the end of the housing section in the second direction and to flow out from the end of the housing section in the first direction.

[0067] According to this aspect, the cooling section's conduit allows gas to flow into the receiving section from its second-direction end and exit from its first-direction end. By configuring the structure such that gas flows in from the second direction aligned with the first and second substrates, the substrates can be cooled more effectively.

[0068] The present invention will now be described in detail. First, referring to... Figures 1 to 3Hereinafter, a summary of a recording apparatus according to an embodiment of the present invention will be described. As an example of the recording apparatus of this embodiment, an inkjet printer 10 (hereinafter, sometimes simply referred to as printer 10) will be used. In addition, in the XYZ coordinate system shown in the figures, the X-axis direction represents the width direction of the medium P on the transport path within the recording apparatus, the Y-axis direction represents the length direction of the medium P that is recorded by the recording section described later, and the Z-axis direction represents the height direction of the apparatus.

[0069] like Figure 1 as well as Figure 3 As shown, the printer 10 is configured as a multifunction printer comprising a main body 12 and a scanning unit 14. The main body 12 includes multiple media storage boxes 16 for storing media P. Each media storage box 16 is detachably mounted from the -X-axis direction side, which is the front side of the main body 12. In this specification, media P, as an example, refers to plain paper, thick paper, photographic paper, or similar paper.

[0070] Furthermore, in the device height direction within the device body 12, between the scanning unit 14 and the media receiving box 16, the media P is recorded in the recording unit 18. After recording, the media P is discharged from the outlet 23a of the discharge unit 23. Additionally, a media holding unit 20 is provided to receive the media P discharged from the outlet 23a.

[0071] like Figure 2 As shown, the printer 10 has a media transport path 21 inside the housing 13. The media transport path 21 includes a straight path 22, a downward discharge path 28, and a feed path 30 connecting the media collection box 16 to the straight path 22. Furthermore, the media transport path 21 includes a turning path 24 and a flipping path 26, thus configuring it for so-called double-sided recording, where recording is performed on the first side of the media P followed by recording on the second side. Additionally, as... Figure 3 As shown, a removable cover 80 is provided on the +X direction side of the frame 13 of the printer 10.

[0072] Along the feeding path 30, a feeding roller 32, a separating roller pair 33, and a conveying roller pair 34 are arranged sequentially in the direction of medium P's transport. The feeding roller 32 is driven to rotate by a drive source (not shown). The separating roller pair 33 separates medium P by clamping it between a driving roller 33a and a driven roller 33b.

[0073] The conveyor roller pair 34 consists of a drive roller and a driven roller. Each drive roller is controlled by a main control unit 100 located within the main body 12 and via a drive source (not shown). Furthermore, although details will be described later, the printer 10 includes a head control unit 90 that controls the line head 48, and the head control unit 90 is mounted on... Figure 3 The frame 101 shown is located on the -X direction side of the cover portion 80. In the printer 10 of this embodiment, it is configured in such a way that the control required to perform the recording operation can be performed using the main body control unit 100 and the head control unit 90.

[0074] In the following description, the structure will be described as follows: in each pair of conveyor rollers mentioned in this specification, one roller is configured as a driven roller, and the other roller is configured as a drive roller that is rotated by a drive source (not shown). Furthermore, in this embodiment, unless otherwise specified, one roller is configured as a paper-pressing gear having multiple teeth on its outer periphery, and as an example, the other roller, i.e., the drive roller, is configured as a rubber roller.

[0075] The medium P stored in the medium storage box 16 is supported on the hopper 17 provided inside the medium storage box 16. The hopper 17 rotates about the rotating shaft 17a provided on the hopper 17 as a fulcrum, lifting the medium P upward. At this time, the feed roller 32 comes into contact with the uppermost medium P supported by the hopper 17 and conveys the medium P downstream in the conveying direction. At this time, although sometimes the next sheet and subsequent sheets of medium P are also conveyed together with the uppermost medium P, the uppermost medium P is separated from the next sheet and subsequent sheets of medium P by the separating roller pair 33, so that only the uppermost medium P is conveyed downstream in the conveying direction.

[0076] A conveyor roller pair 36 is provided downstream of the conveyor roller pair 34 in the conveying direction. In this embodiment, at the position of the conveyor roller pair 36, the feed path 30 is connected to the straight path 22. That is, the feed path 30 is set as a path from the medium receiving box 16 to the conveyor roller pair 36.

[0077] The straight path 22 is configured as a path extending in a straight line, and along the conveying direction, a pair of conveying rollers 36, a conveying mechanism 40 consisting of a drive roller 38, a driven roller 42, and a seamless belt 41, a recording unit 18, and a first baffle 46 are arranged sequentially. In this embodiment, the straight path 22 is set as a path from the pair of conveying rollers 36 to the first baffle 46.

[0078] The recording unit 18 includes a line head 48. A transport mechanism 40 is provided below the line head 48. In this embodiment, the line head 48 is configured to spray ink onto the recording surface of the medium P to perform recording when the medium P is transported to a position on the transport mechanism 40 opposite to the line head 48. The line head 48 is a recording head provided in such a way that the nozzles that spray ink cover the entire width of the medium P, and is configured as a recording head that can record the entire width of the medium without accompanying movement in the width direction of the medium. Although the printer 10 of this embodiment includes a line head 48, it may also include a serial recording head that is mounted on a carriage and moves back and forth in a direction intersecting the medium transport direction while spraying liquid onto the medium to perform recording.

[0079] A conveying mechanism 40, consisting of a drive roller 38, a driven roller 42, and a seamless belt 41, is provided at a position opposite to the conveying head 48. A first baffle 46 is located downstream in this conveying direction. The first baffle 46 is configured such that it can be switched, either by connecting the straight path 22 to the deflection path 24 or by connecting the straight path 22 to the downward discharge path 28, via a drive mechanism (not shown).

[0080] A second baffle 50 is provided above the first baffle 46 in the height direction (Z-axis direction) of the device. Moreover, the second baffle 50 is driven in a manner that is linked to the movement of the first baffle 46 via a linkage mechanism (not shown). The first baffle 46 and the second baffle 50 are subjected to changes in posture under the control of the main control unit 100.

[0081] The downward discharge path 28 extends upward from the straight path 22 in the height direction of the device while curving and reversing. Furthermore, the downward discharge path 28 includes a pair of conveying rollers 52, 54, 56, 58, and 60, and a pair of conveying rollers 62 that constitutes the discharge section 23. The downward discharge path 28 extends from the first baffle 46 to the outlet 23a located downstream of the conveying roller pair 62 in the conveying direction. In other words, the downward discharge path 28 is a media conveying path 21 connected to the straight path 22, and is a path that flips the recording surface of the medium P that has passed through the recording section 18 between the recording section 18 and the discharge section 23 before feeding it into the discharge section 23.

[0082] The medium P, which has been recorded on the recording surface by the recording unit 18, is sequentially held in the downward discharge path 28 from the first baffle 46 along the conveying direction by the conveying roller pair 52, conveying roller pair 54, conveying roller pair 56, conveying roller pair 58, conveying roller pair 60, and conveying roller pair 62, thereby being conveyed on the downward discharge path 28. Then, the medium P is discharged from the outlet 23a toward the medium loading unit 20.

[0083] The flipping path 26 is a path for flipping the medium P, and includes a pair of transport rollers 70, a pair of transport rollers 72, and a pair of transport rollers 74. The medium P, which has previously passed along the straight path 22 of the medium transport path 21 opposite to the recording unit 18, passes through the flipping path 26, causing the surface opposite to the recording unit 18 to flip, and then passes again along the straight path 22 of the medium transport path 21 opposite to the recording unit 18. By having the medium P pass through the flipping path 26, recording can be performed on both surfaces of the medium P.

[0084] Here, refer to Figures 4 to 14 The specific structure of the head control unit 90, which is a main part of the printer 10 in this embodiment, will now be described. As described above, the printer 10 in this embodiment includes: a recording unit 18 having a line head 48 that ejects liquid ink and records media P; and a head control unit 90 that controls the recording unit 18.

[0085] Here, as Figures 9 to 14 As shown, the printer 10 of this embodiment includes a frame 101. The frame 101 is located between the recording unit 18 and the head control unit 90 in the X-axis direction, and divides the arrangement area of ​​the recording unit 18 and the arrangement area of ​​the head control unit 90. Specifically, the +X direction side surface 101a of the frame 101 is the surface on which the head control unit 90 is mounted, and the frame 101b is the -X direction side surface opposite to the surface 101a, and is the surface facing the recording unit 18.

[0086] Moreover, such as Figure 4 As shown, the printer 10 of this embodiment includes a head communication FFC 111 as a first cable. The head communication FFC 111 electrically connects the recording unit 18 and the head control unit 90. By mounting the head control unit 90 on the frame 101, it is possible to... Figures 9 to 12 As shown, there is no need to further wind the flat cable (FFC) within the device after it has been wound to, for example, near the rotating shaft of a door. Therefore, the cable wiring within the device can be shortened.

[0087] Here, as Figures 4 to 8 As shown, the head control unit 90 includes a head driving substrate 91 as a first substrate and a head main substrate 92 as a second substrate. Furthermore, the first substrate and the second substrate are not particularly limited; the head driving substrate 91 can be considered as the second substrate, and the head main substrate 92 as the first substrate. Moreover, as... Figures 4 to 8 As shown, the surfaces 93 of the head drive substrate 91 and the head main substrate 92 are opposed to each other in the opposite direction corresponding to the Z-axis direction.

[0088] As with the printer 10 of this embodiment, by configuring the head control unit 90 to be mounted on the frame 101, the cable wiring within the device can be shortened. Therefore, noise generation can be suppressed, and cost increases can be mitigated. Furthermore, as with the printer 10 of this embodiment, it is preferable that the head control unit 90 has a first substrate and a second substrate, wherein at least a portion of the surfaces of the first substrate and the second substrate are opposed in an opposing direction. Thus, by constructing the head control unit 90 from multiple substrates and overlapping these substrates, the area occupied by the head control unit 90 can be reduced. Moreover, by constructing the head control unit 90 from multiple substrates, for example, only the first substrate can be replaced, simplifying partial replacement of the head control unit 90.

[0089] Furthermore, in the printer 10 of this embodiment, such as Figure 9 , Figures 11 to 14 As shown, the surface 93 of the head drive substrate 91 and the surface 93 of the head main substrate 92 extend in a horizontal direction (a planar direction extending in the X-axis and Y-axis directions) that intersects with the frame 101. This structure makes both surfaces of the first and second substrates easily visible and accessible to the user. Furthermore, although the first and second substrates are arranged in a horizontal direction (the direction intersecting with the frame 101) in this embodiment, they are not limited to this structure. The first and second substrates may also be arranged in a vertical direction (along the direction of the frame).

[0090] Furthermore, in the printer 10 of this embodiment, such as Figure 7 As shown, the head drive board 91 and the head main board 92 are connected via a board-to-board connector 94. This structure allows for easy connection between the first and second boards, and enables communication or power supply between them. Furthermore, it suppresses the distance between the first and second boards and prevents the device from becoming too large.

[0091] Furthermore, in the printer 10 of this embodiment, such as Figure 7As shown, each electrical component of the head main substrate 92, located in the region opposite the head drive substrate 91, is positioned in the gap between the head drive substrate 91 and the head main substrate 92, which are connected via a substrate-to-substrate connector 94, in the Z-axis direction. Alternatively, in this embodiment of the printer 10, the length (for example, L1) in the Z-axis direction of the electrical component disposed between the first substrate and the second substrate and mounted on either the first or second substrate is less than the length L2 in the Z-axis direction of the substrate-to-substrate connector 94. Furthermore, the length L2 in the Z-axis direction of the substrate-to-substrate connector 94 can also be expressed as the distance between the head drive substrate 91 and the head main substrate 92. With this structure, even when electrical components are disposed between the first and second substrates, the length between the first and second substrates in their opposing direction can be suppressed. Other electrical components include, for example, capacitors, memory, and system-on-chip (SoC).

[0092] Furthermore, in the printer 10 of this embodiment, such as Figure 8 As shown, the head drive substrate 91 has a region S1 that does not overlap with the head main substrate 92 when viewed along the Z-axis direction, and a head communication FFC connector 112A, which serves as a head communication FFC connector 112, is provided in the region S1. The head information FFC connector 112 is a connector for a cable (head communication FFC 111) connected to the recording unit 18. If the head drive substrate 91 is regarded as a first substrate and the head main substrate 92 is regarded as a second substrate, it can be seen that the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, and a connector is provided in the first region.

[0093] On the other hand, in the printer 10 of this embodiment, such as Figure 4 , Figure 5 as well as Figure 7 As shown, the head main substrate 92 has a region S2 that does not overlap with the head drive substrate 91 when viewed along the Z-axis direction, and a USB communication cable connector 114, which serves as a connector for a USB communication cable 113 connected to the main control unit 100, is provided in region S2. If the head main substrate 92 is regarded as the first substrate and the head drive substrate 91 as the second substrate, it can be seen that the first substrate has a first region that does not overlap with the second substrate when viewed along the opposing direction, and a connector is provided in the first region.

[0094] Thus, by providing a connector in a region on the first substrate that does not overlap with the second substrate, connecting the cable to the connector becomes easy. Furthermore, the cable connected to the connector in the region on the first substrate that does not overlap with the second substrate is not particularly limited. Cables different from those in this embodiment can also be connected. Additionally, other connectors can be provided in regions other than the region on the first substrate that does not overlap with the second substrate. Moreover, the connector can be provided on any of the surfaces 93 of both the first and second substrates.

[0095] If the above content is expressed differently, then in the printer 10 of this embodiment, the first substrate has a first region (e.g., region S1 and region S2) that does not overlap with the second substrate when viewed along the Z-axis direction, and the second substrate has a second region that does not overlap with the first substrate when viewed along the Z-axis direction. Figure 5 as well as Figure 8 The area S3 shown is provided, and a connector is provided in at least one of the first area and the second area. In this way, by providing a connector in an area on the first substrate that does not overlap with the second substrate, it is easy to connect the cable to the connector.

[0096] If the above content is expressed differently, then in the printer 10 of this embodiment, the first substrate has a first region (e.g., region S1 and region S2) that does not overlap with the second substrate when viewed along the Z-axis direction, and the second substrate has a second region that does not overlap with the first substrate when viewed along the Z-axis direction. Figure 5 as well as Figure 8 As shown in region S3), connectors are provided in both the first and second regions. Thus, by providing connectors in regions on the first substrate that do not overlap with the second substrate, connecting cables to connectors becomes easy.

[0097] Furthermore, in the printer 10 of this embodiment, such as Figure 4 , Figure 5 , Figure 7 as well as Figure 8As shown, the head drive substrate 91 and the head main substrate 92 are aligned in the -Y direction. Alternatively, in the printer 10 of this embodiment, the head main substrate 92, which is the first substrate, has a region S2 as a first region at its end in a first direction corresponding to the +Y direction, and the ends of the head drive substrate 91 and the head main substrate 92 are aligned in a second direction corresponding to the -Y direction. Thus, by setting a structure where the first substrate has a first region at its end in the first direction, and at least a portion of the ends of the first substrate and the second substrate in the second direction are aligned, the area occupied by the first substrate and the second substrate within the device can be suppressed, and the enlargement of the device can be prevented. Furthermore, although in this embodiment the ends are aligned in the -Y direction, it is also possible to set a structure where the ends are aligned in the +Y direction, or a structure where the ends are aligned in the X-axis direction, etc. Moreover, while a structure where the entire edge of the end in the second direction is aligned is preferred, a structure where only a portion of the end in the second direction is aligned is also possible.

[0098] In addition, such as Figures 4 to 8 As shown, both the head drive substrate 91 and the head main substrate 92 have a first surface 93A on which electrical components are mounted, and a second surface 93B opposite to the first surface 93A, serving as surface 93. Here, the second surface 93B of the head drive substrate 91 faces the first surface 93A of the head main substrate 92. Moreover, when the head drive substrate 91 is considered as the first substrate and the head main substrate 92 is considered as the second substrate, as... Figure 8 As shown, the head drive substrate 91, which serves as the first substrate, has a first region (region S1) that does not overlap with the head main substrate 92 when viewed along the Z-axis direction. A head communication FFC connector 112A, serving as a first cable, is provided on the second surface 93B of region S1. By providing this structure, the printer 10 of this embodiment can connect the first substrate (head drive substrate 91) of the recording unit 18 and the head control unit 90. Furthermore, by providing the connector (head communication FFC connector 112A) in region S1 where the first and second substrates do not overlap (oppose), connecting the cable to the connector becomes easier.

[0099] Furthermore, in the printer 10 of this embodiment, such as Figure 5 as well as Figure 8As shown, the second substrate (head main substrate 92) has a second region (region S3) that overlaps with the first substrate (head drive substrate 91) when viewed along the Z-axis direction, and a connector (head communication FFC connector 112B) for connecting a head communication FFC 111B as a first cable is provided on the second surface 93B of region S3. By configuring the printer 10 of this embodiment with such a structure, the second substrate (head main substrate 92) of the recording unit 18 and the head control unit 90 can be connected. Since the connector (head communication FFC connector 112B) is provided on the second surface 93B of the second substrate (head main substrate 92) facing the side opposite to the first substrate (head drive substrate 91), the connection of the first cable (head communication FFC 111B) is easy even if the connector (head communication FFC connector 112B) is provided in the region S3 of the second substrate that overlaps with the first substrate.

[0100] Furthermore, in the printer 10 of this embodiment, the head communication FFC111, namely head communication FFC111A and head communication FFC111B, which serve as the first cable, are both flexible flat cables. Although the information transmission between the recording unit 18 and the head control unit 90 has a significant impact on recording accuracy, noise resistance can be achieved by using flexible flat cables to connect the two. In addition, by adopting such a structure, the first cable can be shortened, thereby providing particularly strong noise resistance.

[0101] In addition, such as Figure 9 , Figure 11 as well as Figure 12 As shown, in this embodiment, when the head main substrate 92 is regarded as the first substrate, the head communication FFC 111A, which is the first cable, has a connection substrate 150 that is connected to the head main substrate 92, which is the first substrate. Moreover, the head main substrate 92 and the connection substrate 150 are connected by a head communication FFC connector 112A, which is also a substrate-to-substrate connector.

[0102] Thus, by configuring the first cable to have a connecting substrate that connects to the first substrate, and the first substrate and the connecting substrate being connected by a substrate-to-substrate connector, maintainability can be improved. Furthermore, it can, for example, prevent the insertion of cables such as FFC at an angle. This is particularly effective when the connector is positioned on the downward-facing side.

[0103] Furthermore, as described above, the printer 10 of this embodiment includes a main control unit 100 for controlling the main body of the device, and a USB communication cable 113 serving as a second cable for electrically connecting the head control unit 90 to the main control unit 100. Moreover, as... Figure 4 as well as Figure 7As shown, a USB communication cable connector 114 is provided in region S2 of the head main substrate 92. That is, both the head drive substrate 91 and the head main substrate 92 have a first surface 93A on which electrical components are mounted, and a second surface 93B opposite to the first surface 93A. The second surface 93B of the head drive substrate 91 faces the first surface 93A of the head main substrate 92. Furthermore, the head main substrate 92 has a third region S2 that does not overlap with the head drive substrate 91 when viewed along the Z-axis. A connector (USB communication cable connector 114) for connecting to the USB communication cable 113 is provided on the first surface 93A of region S2. This structure allows for connection between the second substrate and the main control unit 100. Furthermore, by providing the connector in a region on the second substrate that does not overlap with the first substrate, connecting the second cable to the connector becomes easier. Alternatively, the connector can also be provided in a region on the second substrate that overlaps with the first substrate.

[0104] Here, the information transmission between the second substrate and the recording unit 18 has a greater impact on recording accuracy, while the communication between the first substrate and the second substrate has a smaller impact on recording accuracy. Therefore, by using a low-cost USB communication cable 113 as the second cable and connecting the first substrate and the second substrate using the USB communication cable 113, costs can be suppressed without reducing recording accuracy.

[0105] Moreover, such as Figure 4 As shown, the printer 10 of this embodiment includes a power cable 115, which serves as a third cable, supplying power to the head control unit 90. Furthermore, as... Figure 4 as well as Figure 8 As shown, a power cable connector 116 for connecting to the power cable 115 is provided on the second surface 93B of region S3 of the head main substrate 92. The printer 10 of this embodiment is configured in this way to supply power. Furthermore, since the power cable connector 116 is provided on the second surface 93B of the head main substrate 92 facing the side opposite to the head drive substrate 91, even if the power cable connector 116 is provided in a region overlapping with the head drive substrate 91, connecting the power cable 115 becomes easy.

[0106] Here, as Figures 4 to 8As shown, the printer 10 of this embodiment has a structure in which the second surface 93B of the head drive board 91 and the first surface 93A of the head main board 92 face each other in region S3. Alternatively, it could be a structure in which the first surface 93A of the first board on which the electrical components are mounted faces each other, and the second surface 93B of the second board faces each other. However, it is not limited to this structure. That is, both the first and second boards can be configured such that they each have a first surface 93A on which the electrical components are mounted and a second surface 93B as the opposite side of the first surface 93A, and the second surface 93B of the first board faces each other. In this way, by making the first surface 93A on which the electrical components are mounted the outermost side of both the first and second boards, the possibility of the distance between the first and second boards increasing can be suppressed. Furthermore, although the surface on which the main electrical components are mounted is designated as the first surface 93A, the electrical components can also be mounted on the second surface. In this case, the surface on which the taller components are mounted can be considered the first surface. Alternatively, the side with a larger number of installed electrical components can be considered the first side. The side with the main electrical components installed can also be considered the first side.

[0107] In addition, such as Figure 13 As shown, the printer 10 of this embodiment includes a substrate mounting plate 121 as a substrate assembly part. The substrate mounting plate 121 is mounted on a frame 101 and houses a head drive substrate 91 (serving as a first substrate) and a head main substrate 92 (serving as a second substrate). Furthermore, a new third substrate, the head drive substrate 91 and head main substrate 92, can be installed on the substrate mounting plate 121, replacing the previously mounted head drive substrate 91 and head main substrate 92. For example, if the first substrate is the head drive substrate 91, replacing the head drive substrate 91 allows for changes to the control of the line head 48. Moreover, this structure reduces the need for new components. The printer 10 of this embodiment facilitates substrate replacement through this structure. Additionally, a connector capable of connecting the same cable as the previous substrate needs to be provided on the replaceable substrate. In this case, the third substrate can also be a substrate with installed electrical components different from the first and second substrates.

[0108] In addition, such as Figure 13 As shown, the head drive substrate 91 and the head main substrate 92, which serve as the first substrate and the second substrate, are fixed to the substrate mounting plate 121 using screws 122. Furthermore, the substrate mounting plate 121 is fixed to the frame 101 using screws 123. However, the method of fixing the first substrate and the second substrate relative to the frame 101 is not particularly limited.

[0109] Moreover, such as Figure 14As shown, the printer 10 of this embodiment includes a cooling section 130, which is mounted on the frame 101 and cools the head control section 90. Furthermore, the head control section 90 has a housing section 131 that houses the head drive board 91 and the head main board 92. Alternatively, the housing section 131 may not completely surround the head drive board 91 and the head main board 92. Moreover, the cooling section 130 is configured to cool the interior of the housing section 131. By providing this structure, the printer 10 of this embodiment can cool the head control section 90. Furthermore, since the cooling section 130 and the head control section 90 are mounted on the same frame 101, the cooling efficiency is improved compared to a situation where the cooling section 130 and the head control section 90 are in separate positions.

[0110] In detail, such as Figure 14 As shown, the cooling section 130 includes an air inlet 132, an exhaust section 133, and a conduit 134 for gas to flow between the air inlet 132 and the exhaust section 133. Furthermore, the air inlet 132 is located below the housing section 131, and the exhaust section 133 is located above the housing section 131. By configuring the printer 10 of this embodiment with such a structure, air is inlet from below and exhaust from above, thereby enabling gas flow while utilizing the rising airflow generated by the warmed gas. Therefore, the head control section 90 can be cooled efficiently.

[0111] If we explain the above content from another perspective, then as follows: Figure 14 As shown, the conduit 134 is structured such that gas flows into the receiving portion 131 from its end in the second direction corresponding to the -Y direction, and flows out from its end in the first direction corresponding to the +Y direction. Specifically, it has an inlet on the second direction side relative to the receiving portion 131 and an outlet on the first direction side. By providing this structure and allowing gas to flow in from the second direction aligned with the first and second substrates, the printer 10 of this embodiment can more effectively cool these substrates. In other words, this structure shortens the distance between the inlet for supplying cooler gas and the first and second substrates, thereby enabling more effective cooling of the substrates. Furthermore, the surface on the frame 13, where the inlet and outlet are provided, is not limited to the side surface; it can also be the upper or lower surface.

[0112] Moreover, in the following text, refer to Figures 15 to 23 Features other than the head control unit 90 related to the printer 10 of this embodiment will be described. The printer 10 of this embodiment... Figure 15The region S4 includes a media storage box 16 and multiple wire harnesses 151. Although the media storage box 16 is configured such that its foot 16A can move along the X-axis in the region S4, when the media storage box 16 is close to the wire harnesses 151, the media storage box 16 and the wire harnesses 151 may get caught together when the media storage box 16 is moved.

[0113] Therefore, as Figure 16 as well as Figure 17 As shown, the printer 10 of this embodiment includes a sheet component 161 made of PET (polyethylene terephthalate) to prevent the media storage box 16 from snagging with the cable harness 151 when the media storage box 16 is moved. The sheet component 161 is attached to the fixing sheet metal 163 using double-sided tape 164 and simultaneously attached to the back panel metal 166 along with the fixing sheet metal 163 using a screw 165. Furthermore, the sheet component 161 is held in contact with a plurality of clamps 162 in the Z-axis direction. The cable harness 151 is located below the upper surface portion 162A of the clamps 162.

[0114] In detail, the sheet component 161 is fixed in a tensioned state on the lower surface side of the upper surface portion 162A of the plurality of clamps 162. Therefore, the sheet component 161 and the wire harness 151 do not protrude above the upper surface portion 162A of the clamping member 162. Therefore, the media storage box 16 and the sheet component 161 do not interfere with each other.

[0115] Furthermore, since the sheet component 161 is held together by the screw 165, the fixing sheet metal 163, the back panel metal 166, and the clamp 162, the sheet component 161 will not move inside the printer 10 even if the double-sided tape 164 is peeled off. Additionally, the sheet component 161 is preferably made of a transparent component. This is because, with such a structure, the wiring status can be visually checked even without removing the sheet component 161.

[0116] like Figures 18 to 20 As shown, the method of joint engagement achieved by screws 165 is achieved by providing a clearance and snap-fit ​​structure 166A on the back panel metal part 166 to prevent the thin sheet component 161 from being clamped in unintended locations. As a result, the screws 165 will not loosen due to torque caused by the crushing of the thin sheet component 161. That is, the printer 10 of this embodiment is provided with a structure that uses a thin sheet component 161 made of PET to press the wire harness 151, and the following optimization design is performed: by pressing the wire harness 151 in a space-saving manner while bending the two ends of the thinner material, the necessary rigidity is ensured.

[0117] Furthermore, the printer 10 in this embodiment is capable of... Figure 15 A unit with an ink cartridge 170 is installed in area S5. Furthermore, in area S5... Figure 21 A hole 171A is formed in region S51, specifically at the lower part 171 of the flow channel of ink cartridge 170. By forming the hole 171A, the unit having ink cartridge 170 can be threadedly fixed in region S5. Furthermore, although a motor or gear 173 (not shown) is provided in region S5, the presence of the hole 171A creates a possibility of ink leakage from the hole 171A to the gear 173. While absorbing material 172 could be placed at the lower part 171 of the flow channel of ink cartridge 170 to block the hole 171A, the hole 171A is relatively close to the gear 173 in the Z-axis direction, and the absorbing material 172 is relatively thick. Therefore, it is difficult to place the absorbing material 172 near the gear 173 to block the hole 171A.

[0118] Therefore, in the printer 10 of this embodiment, as Figure 21 As shown, a thin PET sheet 174 is pasted at the position of the hole 171A to replace the absorbent material 172. Although in the printer 10 of this embodiment, the sheet 174 is pasted onto the sheet metal 175, the method of mounting the sheet 174 is not particularly limited. That is, the printer 10 of this embodiment can arrange the absorbent material 172 to avoid the motor, gear 173, etc., and paste the PET sheet 174 on the hole 171A to prevent ink leakage. In addition, absorbent material 172 is arranged on the outside of the sheet 174 to absorb the ink accumulated in the hole 171A.

[0119] Furthermore, when replacing the line head 48, there are instances where the pipe 181, which serves as the ink flow path, and the head communication FFC111 become obstructed. For example... Figure 22 As shown, a pipe 181 and a header communication FFC 111, which are connected to the line header 48, are arranged on the side 101b of the frame 101. For example, when replacing the line header 48, the pipe 181 and the header communication FFC 111 may become obstacles, making it difficult to communicate with the header. Figure 10 as well as Figure 22 The screw 183 shown is close to the target. Therefore, in the printer 10 of this embodiment, as... Figure 22 as well as Figure 23 As shown, multiple clamps 182 are provided for temporarily holding the tube 181 and the head communication FFC111. Additionally, in Figure 22 In the middle, the line header 48 is in a state where it has been removed, thus showing the state where the header communication FFC111 has been removed from the connector (not shown) on the side of the line header 48.

[0120] Furthermore, the printer 10 of this embodiment includes a cover 184 that covers the surface 101b of the frame 101. The cover 184 covers the surface 101b of the frame 101 except when the line head 48 is being replaced, and is concealed by various external components on the surface 101b of the frame 101. Moreover, although the cover 184 is removed when the line head 48 is being replaced, the work required for using the fixing clamp 182 is not increased. In other words, the printer 10 of this embodiment has a structure that allows for easy replacement of the line head 48.

[0121] The present invention is not limited to the embodiments described above, but various modifications can be made within the scope of the invention as set forth in the claims, and these modifications are obviously also included within the scope of the present invention.
