[0011] [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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] (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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] (3) Flexible flat cable configuration As shown in FIG. 4, the FFC 51 includes a cable main body 71, a cable-side connector 72, and a reinforcing plate 73.
[0032] The FFC 52 includes a cable main body 81, a cable-side connector 82, and a reinforcing plate 83. 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.
[0033] 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.
[0034] The reinforcing plates 73, 83 are plate-like members that extend along the length of the cable main bodies 71, 81, which are formed in the shape of a long strip, and are attached to the cable main bodies 71, 81. 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 where the reinforcing plates 73, 83 are attached.
[0035] One end of the FFC 51 and one end of the FFC 52 are respectively connected to the board-side connector 61 and the board-side connector 62 of the main board 41, and the other ends of the FFC 51 and the FFC 52 are respectively welded to the board-side connecting portion 63 and the board-side connecting portion 64 of the carriage board 42. As a result, as shown in Fig. 5, the cable main bodies 71 and 81 are arranged with the surface of the cable main body 71 and the surface of the cable main body 81 facing each other and overlapping each other.
[0036] The reinforcing plates 73 and 83 are attached to the surfaces of the cable main body 71 and the cable main body 81, respectively, so that the reinforcing plates 73 and 83 are positioned opposite each other and overlap when the cable main body 71 and the cable main body 81 are overlapped as described above.
[0037] The reinforcing plates 73 and 83 are fixed in place by fixing members 92 attached to a frame 91 supported by the housing 2, with the reinforcing plates 73 and 83 overlapping each other. The fixing member 92 includes bending members 101 and 102 and cylindrical members 103 and 104 .
[0038] The bending member 101 is formed by joining one side of a rectangular plate-shaped member 101a and one side of a rectangular plate-shaped member 101b, and is bent at 90° at this joint.
[0039] The bending member 102 is formed by joining one side of a rectangular plate-shaped member 102a and one side of a rectangular plate-shaped member 102b, and is bent at 90° at this joint.
[0040] Bending member 101 is placed on the surface of frame 91 so that the surfaces of plate-like members 101a and 101b are perpendicular to the surface of frame 91. Bending member 102 is placed on the surface of frame 91 so that the surfaces of plate-like members 102a and 102b are perpendicular to the surface of frame 91.
[0041] The columnar members 103 and 104 are placed on the surface of the frame 91 so that their columnar axes are perpendicular to the surface of the frame 91 . The bending members 101 and 102 are installed on the surface of the frame 91 so that the surfaces of the plate-shaped members 101a and 102a are parallel to each other, the surfaces of the plate-shaped members 101b and 102b are parallel to each other, and the overlapping reinforcing plates 73 and 83 are housed between the bending members 101 and 102.
[0042] The columnar member 103 is installed near the plate-like member 101a so that the cable main bodies 71 and 81 can be disposed between the columnar member 103 and the plate-like member 101a. The columnar member 104 is installed near the plate-like member 102a so that the cable main bodies 71 and 81 can be disposed between the columnar member 104 and the plate-like member 102a.
[0043] As a result, the fixing member 92 fixes the reinforcing plate 73 and the reinforcing plate 83 in a state in which the reinforcing plate 73 and the reinforcing plate 83 overlap each other. (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, an FFC 52, a reinforcing plate 73, a reinforcing plate 83, and a fixing member 92.
[0044] 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.
[0045] 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 .
[0046] The reinforcing plate 73 is attached to the FFC 51. The reinforcing plate 83 is attached to the FFC 52. The fixing member 92 fixes the reinforcing plate 73 and the reinforcing plate 83 in a state where the reinforcing plate 73 and the reinforcing plate 83 overlap each other.
[0047] In such an image forming apparatus 1, by fixing the reinforcing plates 73 and 83 with the fixing member 92, it is possible to reduce misalignment along the length of the FFCs 51 and 52 when the FFCs 51 and 52 are stacked and assembled, thereby suppressing the generation of noise emitted from the FFCs 51 and 52.
[0048] 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.
[0049] In addition, 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, the board side connection portion 64 corresponds to the fourth connection portion, the reinforcing plate 73 corresponds to the first reinforcing plate, and the reinforcing plate 83 corresponds to the second reinforcing plate.
[0050] [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.
[0051] The image forming apparatus 1 of the second embodiment differs from the first embodiment in that the configuration of the FFCs 51 and 52 is changed and the shapes of the reinforcing plates 73 and 83 are changed. As shown in FIG. 6, the FFCs 51 and 52 of the second embodiment are connected to each other by connecting members 111 and 112.
[0052] The FFC51 and the FFC52 are arranged parallel to each other along their lengthwise direction, and are connected to each other by placing a connecting member 111 between the FFC51 and the FFC52 at one end side of the FFC51 and the FFC52, and by placing a connecting member 112 between the FFC51 and the FFC52 at the other end side of the FFC51 and the FFC52.
[0053] The connecting members 111 and 112 are made of a bendable material. The connecting members 111 and 112 may be made of the same material as the insulating film that forms the cable main bodies 71 and 81, for example.
[0054] As a result, by bending the connecting members 111 and 112 along the length direction of the FFCs 51 and 52, the surfaces of the cable main body 71 and the cable main body 81 are arranged so as to face each other.
[0055] Hereinafter, the FFCs 51 and 52 formed into a single strip shape by the connecting members 111 and 112 will be collectively referred to as a connected FFC 50. In the second embodiment, of the four sides of the reinforcing plate 73 formed in a rectangular shape, sides 73a and 73b that intersect with the length direction of the FFC 51 intersect non-perpendicularly with the length direction.
[0056] Similarly, in the reinforcing plate 83 of the second embodiment, of the four sides constituting the rectangular reinforcing plate 83, sides 83a and 83b that intersect with the length direction of the FFC 52 intersect non-perpendicularly with the length direction.
[0057] The reinforcing plates 73 and 83 are arranged such that, when the connecting members 111, 112 are not bent, the sides 73a and 83a are positioned on a straight line SL1, and the sides 73b and 83b are positioned on a straight line SL2.
[0058] In the image forming apparatus 1 configured as described above, the FFC 51 and the FFC 52 are connected to each other to form a single strip. The reinforcing plates 73 and 83 are arranged so that the reinforcing plates 73 and 83 face each other by bending the connected FFC 50 along the length direction of the connected FFC 50. In the image forming apparatus 1 configured as described above, because the FFC 51 and the FFC 52 are connected to each other, when the FFC 51 and the FFC 52 are superimposed and assembled, misalignment along the length direction of the FFCs 51 and 52 caused by welding the FFCs 51 and 52 can be suppressed, and noise emitted from the FFCs 51 and 52 can be suppressed.
[0059] Furthermore, sides 73a and 73b of reinforcing plate 73 and sides 83a and 83b of reinforcing plate 83 intersect non-perpendicularly with the longitudinal direction of FFCs 51 and 52. Reinforcing plates 73 and 83 are arranged such that sides 73a and 83a are aligned on a straight line SL1 and sides 73b and 83b are aligned on a straight line SL2 when connecting members 111 and 112 are not bent. In this image forming apparatus 1, when connecting members 111 and 112 are bent along the longitudinal direction of FFCs 51 and 52 so that the surfaces of cable main 71 and cable main 81 face each other, as shown in FIG. 6 , misalignment occurs due to the radius of curvature of the inner side of cable main 71 and cable main 81 being smaller than that of the outer side at the curved portion. This makes it easier for reinforcing plates 73 and 83 to overlap.
[0060] In the embodiment described above, the connecting FFC 50 corresponds to the connecting flexible flat cable, and the length direction of the connecting FFC 50 corresponds to the extending direction of the connecting flexible flat cable.
[0061] Moreover, the side 73a corresponds to the first side, the side 73b corresponds to the second side, the side 83a corresponds to the third side, the side 83b corresponds to the fourth side, and the straight lines SL1 and SL2 correspond to the same straight line. [Third embodiment] A third embodiment of the present disclosure will be described below with reference to the drawings. In the third embodiment, differences from the second embodiment will be described. The same reference numerals will be used to designate common components.
[0062] The image forming apparatus 1 of the third embodiment differs from the second embodiment in that the shapes of the reinforcing plates 73 and 83 are changed. As shown in Figure 7, the reinforcing plate 73 of the third embodiment is a rectangular plate-like member consisting of two sides parallel to the length direction of the cable main body 71 and two sides perpendicular to the length direction of the cable main body 71, and has a shape in which a recess 73c is formed on the side of the two sides perpendicular to the length direction that is closer to the cable main body 81.
[0063] The reinforcing plate 83 of the third embodiment is a rectangular plate-shaped member consisting of two sides parallel to the longitudinal direction of the cable main body 81 and two sides perpendicular to the longitudinal direction of the cable main body 71, and has a shape in which a convex portion 83c is formed on the side of the two sides perpendicular to the longitudinal direction that is farther from the cable main body 71.
[0064] The recessed portion 73c and the protruding portion 83c are formed in shapes that allow them to fit together. Therefore, when the connecting members 111, 112 are bent along the longitudinal direction of the FFCs 51, 52 so that the reinforcing plates 73, 83 are positioned inside the cable main bodies 71, 81, the reinforcing plates 73, 83 are overlapped with the recessed portions 73c and the protruding portions 83c fitted together.
[0065] In the image forming apparatus 1 configured as described above, the reinforcing plates 73 and 83 are formed in shapes that allow them to fit together. In the image forming apparatus 1 configured as described above, the FFCs 51 and 52 can be aligned at the positions where the reinforcing plates 73 and 83 fit together.
[0066] [Fourth embodiment] A fourth embodiment of the present disclosure will be described below with reference to the drawings. In the fourth embodiment, differences from the first embodiment will be described. The same reference numerals will be used to designate common components.
[0067] The image forming apparatus 1 of the fourth embodiment differs from the first embodiment in that the shapes of the reinforcing plates 73 and 83 are changed. As shown in FIG. 8, the reinforcing plate 73 of the fourth embodiment differs from the first embodiment in that the length along the direction perpendicular to the longitudinal direction of the FFC 51 (i.e., the width direction of the FFC 51) is greater than the width of the cable main body 71 (i.e., the length along the width direction of the FFC 51).
[0068] Similarly, the reinforcing plate 83 of the fourth embodiment differs from the first embodiment in that the length along a direction perpendicular to the longitudinal direction of the FFC 52 (i.e., the width direction of the FFC 52) is greater than the width of the cable main body 71 (i.e., the length along the width direction of the FFC 52).
[0069] Then, with the reinforcing plates 73 and 83 stacked on top of each other, the convex portions of the reinforcing plates 73 and 83 protruding from the cable main bodies 71 and 81 are fitted into the concave portions 94a formed in the frame 94 supported by the housing 2, thereby fixing the reinforcing plates 73 and 83 to the frame 94.
[0070] In such an image forming apparatus 1, by fixing the reinforcing plates 73 and 83 by the recesses 94a, it is possible to reduce misalignment along the length of the FFCs 51 and 52 when the FFCs 51 and 52 are stacked and assembled, thereby suppressing the generation of noise emitted from the FFCs 51 and 52.
[0071] In the embodiment described above, the recess 94a corresponds to the fixing 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.
[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. [Explanation of symbols]
