[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-195971 Summary of the Invention [Problem to be solved by the invention]

[0004] When assembling two flexible flat cables to a control board, there was a problem in that the distance between the two flexible flat cables changed, which could increase the noise emitted from the flexible flat cables.

[0005] The present disclosure aims to suppress the generation of noise radiated from a flexible flat cable. [Means for solving the problem]

[0006] One aspect of the present disclosure is a control device that controls a preset control target, and includes a first substrate, a second substrate, a first flexible flat cable, and a second flexible flat cable.

[0007] The first substrate includes a first connection portion and a second connection portion for inputting and outputting electrical signals. The second substrate includes a third connection portion and a fourth connection portion for inputting and outputting electrical signals. The first flexible flat cable has one end connected to the first connection portion of the first substrate and the other end connected to the third connection portion of the second substrate.

[0008] The second flexible flat cable has one end connected to the second connection portion of the first substrate and the other end connected to the fourth connection portion of the second substrate. The first flexible flat cable has a first curved portion that curves between the first substrate and the second substrate, and extends from the first curved portion to the second substrate toward a first support portion that supports the first flexible flat cable on the main body of the control device.

[0009] The second flexible flat cable has a second curved portion that curves between the first substrate and the second substrate, and extends from the second curved portion to the second substrate toward a second support portion that supports the second flexible flat cable on the main body of the control device.

[0010] The direction in which the first bending portion and the second bending portion face inward is defined as a first direction, and the first connecting portion and the first supporting portion are disposed in the first direction of the first bending portion. The second connection portion and the second support portion are disposed in the first direction of the second bending portion.

[0011] The second curved portion is disposed between the first curved portion and the second connection portion in the first direction. The second flexible flat cable includes an extension member that extends from a position between the second connection portion and the second curved portion of the first substrate toward the first flexible flat cable.

[0012] The control device of the present disclosure configured in this manner has an extension member arranged between the first flexible flat cable and the second flexible flat cable that regulates the position of the first flexible flat cable so that the first flexible flat cable does not get close to the second flexible flat cable, making it easier to maintain a constant distance between the first and second flexible flat cables and suppressing the generation of noise radiated from the flexible flat cables.

[0014] [First embodiment] A first embodiment of the present disclosure will be described below with reference to the drawings. (1) Overall structure As shown in Fig. 1, the image forming apparatus 1 of this embodiment includes a housing 2 having a substantially rectangular parallelepiped shape. In the following description, in order to simply explain the relative positions of the components of the image forming apparatus 1, when the image forming apparatus 1 is installed on a horizontal surface, the direction perpendicular to the horizontal surface is defined as the up-down direction, the direction toward which the operation surface of an operation panel 5 (described later) faces is defined as the front, and the direction opposite to the front is defined as the rear. The left-right direction is the left-right direction when the image forming apparatus 1 is viewed from the front.

[0015] Image forming apparatus 1 includes a main unit 3 and a reading unit 4 that reads an image. Inside main unit 3, there is provided a control unit 11 that is configured to be able to control each unit of image forming apparatus 1, and an image forming unit 12 that is configured to be able to record an image on a recording medium. Note that control unit 11 and image forming unit 12 are not shown in Fig. 1 but are shown in Fig. 2.

[0016] The reading unit 4 is connected to the main unit 3 via a hinge, and is configured to be rotatable relative to the main unit 3 around an axis extending in the left-right direction near the rear end of the reading unit 4. This allows the reading unit 4 to be displaced between a closed position where it closes an opening formed on the top surface of the main unit 3, and an open position where it opens this opening.

[0017] An operation panel 5 operated by a user is provided on the front surface of the image forming apparatus 1. The operation panel 5 includes input devices (for example, a touch panel, various buttons, and switches) that the user operates to give various commands to the image forming apparatus 1, and output devices (for example, a liquid crystal display device and various lamps) that notify the user of the operating status of the image forming apparatus 1, etc.

[0018] Below the operation panel 5, there is provided an outlet 6 for removing the recording medium on which an image has been formed in the image forming unit 12. Below the outlet 6, there is attached a medium supply cassette 7 that stores the recording medium to be supplied to the image forming unit 12.

[0019] The image forming apparatus 1 is an inkjet printer, and the image forming unit 12 includes, as shown in FIG. 2, a recording head 31, a carriage 32, a carriage motor 33, a line feed motor 34, a head driver IC 35, a carriage motor driver IC 36, and a line feed motor driver IC 37.

[0020] The recording head 31 is an ejection head configured to eject ink droplets, and is a so-called inkjet head. The recording head 31 ejects ink droplets to form an image on the recording medium as the carriage 32 moves across the recording medium in the main scanning direction. The carriage motor 33 is a DC motor and functions as a drive source for reciprocating the carriage 32. The line feed motor 34 is also a DC motor and functions as a drive source for rotating a transport roller that transports paper in the sub-scanning direction.

[0021] Based on a head control signal from the control unit 11, the head driver IC 35 outputs a head drive signal to the recording head 31 for ejecting ink droplets. The carriage motor driver IC 36 outputs a carriage motor drive signal to the carriage motor 33 based on a carriage motor control signal from the control unit 11 to drive the carriage motor 33 to rotate.

[0022] Based on a line feed motor control signal from the control unit 11, the line feed motor driver IC 37 outputs a line feed motor drive signal to the line feed motor 34 for driving the line feed motor 34 to rotate.

[0023] The control unit 11 includes a CPU 21, a ROM 22, a RAM 23, and an ASIC 24. ASIC stands for Application Specific Integrated Circuit. The CPU 21, ROM 22, RAM 23, and ASIC 24 are connected via a bus 25 so as to be able to input and output data to and from one another.

[0024] The CPU 21 is configured to comprehensively control each unit of the image forming apparatus 1. The ROM 22 stores computer programs executed by the CPU 21. The RAM 23 is used as a work area when the CPU 21 executes the computer programs.

[0025] When the CPU 21 receives an image formation job, the CPU 21 executes an image formation program stored in the ROM 22 to output an image formation command to the ASIC 24 . Based on an image formation command from the CPU 21, the ASIC 24 outputs the head control signal, carriage motor control signal, and line feed motor control signal to the head driver IC 35, carriage motor driver IC 36, and line feed motor driver IC 37, respectively.

[0026] (2) Connection via flexible flat cable 3, the ASIC 24 is mounted on a printed circuit board 41. Hereinafter, the printed circuit board 41 will be referred to as a main board 41.

[0027] The recording head 31 includes a printed circuit board 42 and a flexible printed circuit board 43. Hereinafter, the printed circuit board 42 will be referred to as a carriage board 42, and the flexible printed circuit board 43 will be referred to as an FPC 43.

[0028] The carriage board 42 and the FPC 43 are connected so as to be able to input and output electrical signals to and from each other. The head driver IC 35 is mounted on the FPC 43. The main board 41 and the carriage board 42 are connected by flexible flat cables 51 and 52 (hereinafter referred to as FFCs 51 and 52) so as to be able to input and output electrical signals to and from each other.

[0029] On the first surface 41a of the main board 41, a board-side connector 61 for connecting the FFC 51 and a board-side connector 62 for connecting the FFC 52 are mounted. The board-side connectors 61 and 62 are each configured with a plurality of terminals for connecting to the plurality of conductors of the FFCs 51 and 52, which are arranged at equal intervals along a preset terminal arrangement direction.

[0030] On the first surface 42a of the carriage board 42, a board-side connecting portion 63 for connecting the FFC 51 and a board-side connecting portion 64 for connecting the FFC 52 are mounted. Each of the board-side connection portions 63 and 64 is configured with a plurality of terminals arranged at equal intervals along a predetermined terminal arrangement direction for connecting to each of the plurality of conductors of the FFCs 51 and 52. The plurality of terminals of the board-side connection portions 63 and 64 are connected to the plurality of conductors of the FFCs 51 and 52 by welding.

[0031] The ASIC 24 outputs the pattern signal FIRE, the selection signal SIN, and the clock signal CLK as the head drive signals to the head driver IC 35 via the FFC 51. The pattern signal FIRE is a signal that indicates a plurality of ejection patterns in which the recording head 31 ejects ink droplets.

[0032] The selection signal SIN is a signal for selecting one ejection pattern from among a plurality of ejection patterns. The clock signal CLK is a signal for synchronizing the pattern signal FIRE and the selection signal SIN.

[0033] The pattern signal FIRE, the selection signal SIN, and the clock signal CLK are, for example, differential signals of the LVDS system, where LVDS stands for Low Voltage Differential Signaling. Furthermore, a power supply line and a ground line (not shown) connect the main board 41 and the carriage board 42 via the FFC 52, thereby supplying driving power to the recording head 31.

[0034] (3) Flexible flat cable configuration As shown in FIG. 4, the main board 41 is installed in the housing 2 so that the first surface 41a faces the left side of the image forming apparatus 1, for example.

[0035] Furthermore, the board-side connectors 61 and 62 are installed on the first surface 41a of the main board 41 so that the terminal arrangement direction of the board-side connectors 61 and 62 coincides with the front-rear direction of the image forming apparatus 1, for example.

[0036] The board-side connector 61 and the board-side connector 62 are arranged such that the board-side connector 62 is arranged above the board-side connector 61 and the board-side connector 61 and the board-side connector 62 face each other.

[0037] The FFC 51 includes a cable main body 71, a cable-side connector 72, and a reinforcing plate 73. The FFC 52 includes a cable main body 81, a cable-side connector 82, a reinforcing plate 83, and an extending member 84.

[0038] The cable main body 71, 81 includes a plurality of linear conductors and two insulating films that cover the conductors. The cable main body 71, 81 is formed into a flexible band shape by sandwiching the plurality of conductors, which are arranged parallel to each other, between the two insulating films.

[0039] The connectors 72 and 82 are attached to one end of the long, strip-shaped cable main bodies 71 and 81, respectively. The connectors 72 and 82 include a plurality of terminals that are connected to the plurality of conductors of the cable main bodies 71 and 81, respectively.

[0040] The reinforcing plates 73, 83 are plate-like members attached to the cable main bodies 71, 81 so as to extend from the connectors 72, 82 along the longitudinal direction of the cable main bodies 71, 81, which are formed in the shape of a long strip. The reinforcing plates 73, 83 are made of, for example, polyimide, and can increase the strength of the cable main bodies 71, 81 in the vicinity of the connectors 72, 82.

[0041] By connecting FFC 51 and FFC 52 to board-side connector 61 and board-side connector 62 of main board 41, cable mains 71 and 81 are arranged so that the surfaces of cable main 71 and cable main 81 face each other.

[0042] The reinforcing plate 83 is attached to the cable main body 81 so that the reinforcing plate 83 is positioned between the cable main body 71 and the cable main body 81 when the FFC 51 and the FFC 52 are connected to the board-side connector 61 and the board-side connector 62 of the main board 41, respectively.

[0043] The cable main bodies 71 and 81 extend from the connectors 72 and 82, respectively, toward the left of the image forming apparatus 1, and curve upward as they extend toward the left, forming curved portions 71a and 81a. The cable main bodies 71 and 81 then extend further toward the right of the image forming apparatus 1 from the curved portions 71a and 81a, respectively. Therefore, the curved portion 81a is disposed inside the curved portion 71a.

[0044] As the cable bodies 71 and 81 extend toward the right of the image forming device 1, they are positioned so that the surfaces of the cable bodies 71 and 81 are close to each other and facing each other by a regulating member 92 installed on a frame 91 supported by the housing 2.

[0045] Then, as the cable main bodies 71 and 81 extend further from the restricting member 92 toward the right of the image forming apparatus 1, tape 93 is wound around the cable main bodies 71 and 81 with the surfaces of the cable main body 71 and the cable main body 81 in contact with each other. As a result, the cable main bodies 71 and 81 are maintained in an overlapping state while extending from the tape 93 to the recording head 31.

[0046] The cable main bodies 71 and 81 are fixed by a fixing member 94 while extending from the tape 93 to the recording head 31. As a result, the cable main bodies 71 and 81 move in accordance with the movement of the recording head 31 between the fixing member 94 and the recording head 31.

[0047] The cable main bodies 71 and 81 are bent multiple times while extending from the tape 93 to the recording head 31. As a result, the cable main bodies 71 and 81 are connected to the recording head 31 such that the arrangement direction of the multiple conductors in the cable main bodies 71 and 81 coincides with the vertical direction of the image forming apparatus 1.

[0048] The extending member 84 of the FFC 52 is a plate-like member that extends upward from the reinforcing plate 83 toward the curved portion 71a. The extending member 84 is made of, for example, polyimide. That is, the reinforcing plate 83 and the extending member 84 are integrally molded from a resin material.

[0049] 4 and 5, the extension member 84 has a notch 84a formed by cutting the extension member 84 along a direction perpendicular to the extension direction of the extension member 84. A part of the cable main 71 is housed in the notch 84a.

[0050] (4) Effects The image forming apparatus 1 configured as above controls the recording head 31, and includes a main board 41, a carriage board 42, an FFC 51, and an FFC 52.

[0051] The main board 41 includes a board-side connector 61 and a board-side connector 62 for inputting and outputting electrical signals. The carriage board 42 includes a board-side connection portion 63 and a board-side connection portion 64 for inputting and outputting electrical signals.

[0052] One end of the FFC 51 is connected to a board-side connector 61 of the main board 41, and the other end is connected to a board-side connection portion 63 of the carriage board . One end of the FFC 52 is connected to a board-side connector 62 of the main board 41, and the other end is connected to a board-side connection portion 64 of the carriage board .

[0053] The FFC 51 has a curved portion 71a that curves between the main board 41 and the carriage board 42, and extends from the curved portion 71a to the carriage board 42 toward a regulating member 92 that supports the FFC 51 on the housing 2 of the image forming apparatus 1.

[0054] The FFC 52 has a curved portion 81a that curves between the main board 41 and the carriage board 42, and extends from the curved portion 81a to the carriage board 42 toward a regulating member 92 that supports the FFC 52 on the housing 2 of the image forming apparatus 1.

[0055] As shown in Figure 4, the direction facing inward of the curved portion 71a and the curved portion 81a is defined as a first direction DI, and the direction facing outward of the curved portion 71a and the curved portion 81a (i.e., the opposite direction to the first direction DI) is defined as a second direction DO, and the board side connector 61 and the regulating member 92 are arranged in the first direction DI of the curved portion 71a.

[0056] The board-side connector 62 and the restricting member 92 are arranged in the first direction DI of the curved portion 81a. The curved portion 81a is disposed between the curved portion 71a and the board-side connector 62 in the first direction DI.

[0057] The FFC 52 includes an extension member 84 that extends from a position between the board-side connector 62 of the main board 41 and the curved portion 81a toward the FFC 51. In such an image forming apparatus 1, the extension member 84 arranged between the FFC51 and the FFC52 regulates the position of the FFC51 so that the FFC51 does not come close to the FFC52, making it easier to maintain a constant distance between the FFC51 and the FFC52 and suppressing the generation of noise emitted from the FFC51 and the FFC52.

[0058] Further, extension member 84 is formed of the same material as reinforcing plate 83, which is disposed near the end of FFC 52 that is connected to board-side connector 62 and reinforces FFC 52. Extension member 84 extends from reinforcing plate 83 toward FFC 51. In image forming apparatus 1, by using the same material for reinforcing plate 83 and extension member 84, reinforcing plate 83 and extension member 84 can be manufactured by integral molding, and the work of connecting extension member 84 to reinforcing plate 83 can be omitted.

[0059] Furthermore, the extension member 84 extends toward the FFC 51 while being positioned on the opposite side of the board-side connector 62 from the board-side connector 61 (i.e., above the board-side connector 62 in this embodiment). This type of image forming apparatus 1 makes it easier to maintain a constant distance between the FFC 51 and the FFC 52 than when the extension member 84 extends toward the FFC 51 while being positioned on the same side of the board-side connector 62 as the board-side connector 61 (i.e., below the board-side connector 62 in this embodiment).

[0060] Further, the extending member 84 is formed with a notch 84a that accommodates a portion of the FFC 51. In this image forming apparatus 1, the position of the FFC 51 can be further restricted by the notch 84a, and the distance between the FFC 51 and the FFC 52 can be more easily maintained constant.

[0061] In the embodiment described above, the recording head 31 corresponds to the object to be controlled, the image forming device 1 corresponds to the control device, the main board 41 corresponds to the first board, the carriage board 42 corresponds to the second board, the FFC 51 corresponds to the first flexible flat cable, and the FFC 52 corresponds to the second flexible flat cable.

[0062] Furthermore, the board side connector 61 corresponds to the first connection portion, the board side connector 62 corresponds to the second connection portion, the board side connection portion 63 corresponds to the third connection portion, and the board side connection portion 64 corresponds to the fourth connection portion.

[0063] Furthermore, the curved portion 71a corresponds to the first curved portion, the curved portion 81a corresponds to the second curved portion, the housing 2 corresponds to the main body, the regulating member 92 corresponds to the first support portion and the second support portion, and the cutout portion 84a corresponds to the cable accommodating portion.

[0064] [Second embodiment] A second embodiment of the present disclosure will be described below with reference to the drawings. In the second embodiment, only the parts that are different from the first embodiment will be described. The same reference numerals will be used to designate common components.

[0065] The image forming apparatus 1 of the second embodiment differs from the first embodiment in that the shape of the extension member 84 is changed. As shown in FIG. 6, the extension member 84 of the second embodiment includes a first plate-shaped member 84b and a second plate-shaped member 84c.

[0066] The first plate-shaped member 84b extends upward from the reinforcing plate 83 toward the curved portion 71a. The second plate-shaped member 84c extends upward from the first plate-shaped member 84b along a second extending direction ED2 that is different from the first extending direction ED1 in which the first plate-shaped member 84b extends.

[0067] In the image forming apparatus 1 configured in this manner, the extension member 84 includes a first plate-shaped member 84b extending from a position between the board-side connector 62 and the curved portion 81a, and a second plate-shaped member 84c extending from the first plate-shaped member 84b along a second extension direction ED2 that is different from the first extension direction ED1 in which the first plate-shaped member 84b extends. In this type of image forming apparatus 1, the second plate-shaped member 84c can further restrict the position of the FFC 51, making it easier to maintain a constant distance between the FFC 51 and the FFC 52.

[0068] In the embodiment described above, the first plate-shaped member 84b corresponds to the first member, and the second plate-shaped member 84c corresponds to the second member. Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment and can be implemented in various modifications.

[0069] [Variation 1] In the above embodiment, the extension member 84 extends upward from the reinforcing plate 83 toward the curved portion 71a. However, the extension member 84 may extend downward from the reinforcing plate 83 toward the curved portion 71a.

[0070] [Variation 2] In the above embodiment, the cable main bodies 71 and 81 are supported by the restricting member 92. However, the cable main body 71 and the cable main body 81 may be supported by separate restricting members.

[0071] [Variation 3] In the above embodiment, the reinforcing plate 83 and the extending member 84 are formed of the same material, but the reinforcing plate 83 and the extending member 84 may be formed of different materials.

[0072] In the above embodiments, multiple functions of one component may be realized by multiple components, or one function of one component may be realized by multiple components. Furthermore, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Furthermore, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
