[0072] [Arrangement method of the first harness 61] 6, the female connector 61A of the first harness 61 is placed on the upper end side of the inclined portion 32. When the female connector 61A is placed on the upper end side of the inclined portion 32, the female connector 61A slides down the inclined portion 32 due to its own weight, passes under the protrusion 43, and hits the tapered portion 42A of the third rib 42. The female connector 61A that hits the tapered portion 42A of the third rib 42 is guided into the through hole 32A, passes through the through hole 32A, and protrudes from the cylindrical body 32B to the bottom of the device.
[0073] Then, the female connector 61A protruding from the cylindrical body 32B toward the bottom of the device is connected to the male connector 26A.
[0074] Furthermore, when the middle portion of the first harness 61 is placed on the upper end side of the inclined portion 32, the middle portion of the first harness 61 slides down the inclined portion 32 due to its own weight and comes into contact with the first rib 41. At this time, the middle portion of the first harness 61 slides below the device of the first pressing portion 44. As a result, the first harness 61 is disposed on the inclined portion 32 as shown in FIG.
[0075] [Effect] In the image forming apparatus 10 of the embodiment, a guide part 30 is provided between the image reading unit 12 and a board box 24 disposed below the image reading unit 12 and housing a control board 26, and supports a harness 60, the guide part 30 having an inclined portion 32 on its upper surface that inclines downward, and a first harness 61 is disposed on the inclined portion 32 and connects the image reading unit 12 and the control board 26 (see FIG. 3).
[0076] The guide component 30 is provided between the image reading unit 12 and the board box 24 that is provided below the image reading unit 12 and that houses the control board 26, and supports the harness 60, and has an inclined portion 32 on its upper surface that inclines downward. When the first harness 61 is placed on the upper end side of the inclined portion 32, the first harness 61 slides down the inclined portion 32 and is positioned on the lower end side of the inclined portion 32. Therefore, it is easier for the user to position the first harness 61, compared to when the entire guide component 30 that supports the first harness 61 located between the image reading unit 12 and the board box 24 is a horizontal surface.
[0077] In the image forming apparatus 10 of the embodiment, the inclined portion 32 is inclined downward toward the inside of the apparatus (see FIG. 4).
[0078] The inclined portion 32 is inclined downward toward the inside of the device, so that the first harness 61 is disposed inside the device. Therefore, damage to the first harness 61 is suppressed compared to a case in which the inclined portion 32 is inclined downward toward the outside of the device. Also, since the first harness 61 is disposed inside the device, the effect of noise on the first harness 61 is reduced compared to a case in which the first harness 61 is disposed outside the device.
[0079] In the embodiment of the image forming apparatus 10, a counterbalance 22 is provided that applies an opening force to a pressing means provided on the image reading unit 12, and the guide part 30 is disposed between the counterbalance 22 and the base box 24 (see FIG. 2).
[0080] The guide part 30 is arranged between the counterbalance 22 and the circuit board box 24, and therefore, compared to a case in which the inclined part 32 is arranged offset from the counterbalance 22, it is easier to arrange the first harness 61 at a desired position through between the counterbalance 22 and the circuit board box 24.
[0081] The image forming apparatus 10 of the embodiment includes a plurality of harnesses 60, each of which is disposed along a different surface of the guide component 30 (see FIG. 2).
[0082] The multiple harnesses 60 are arranged along different faces of the guide component 30, so that one harness 60 and another harness 60 are arranged separately on different faces. Therefore, the influence of radio waves between the harnesses 60 is reduced compared to when the multiple harnesses 60 are arranged on the same face of the guide component 30.
[0083] In the image forming apparatus 10 of the embodiment, the second harness 62 and the first harness 61 are disposed along orthogonal surfaces of the guide component 30 (see FIG. 2).
[0084] The second harness 62 and the first harness 61 are disposed along perpendicular faces of the guide component 30, so that the second harness 62 and the first harness 61 are disposed perpendicular to each other. Therefore, the influence of radio waves between the harnesses is reduced compared to when the second harness 62 and the first harness 61 are disposed in parallel.
[0085] In the image forming apparatus 10 of the embodiment, a first rib 41 that protrudes upward and supports a first harness 61 is formed on the lower end side of the inclined portion 32 (see FIG. 4).
[0086] A first rib 41 that protrudes upward and supports the first harness 61 is formed on the lower end side of the inclined portion 32, so that the first harness 61 comes into contact with the first rib 41 when sliding down the inclined portion 32. Therefore, the first harness 61 can be positioned at a desired position on the inclined portion 32.
[0087] In the image forming apparatus 10 of the embodiment, a second rib 47 is formed on the upper end side of the inclined portion 32, protruding upward and partitioning the arrangement space of the first harness 61 (see FIG. 4).
[0088] A second rib 47 that protrudes upward and separates the arrangement space of the first harness 61 is formed on the upper end side of the inclined portion 32, thereby allowing the first harness 61 arranged on the inclined portion 32 to be positioned.
[0089] In the image forming apparatus 10 of the embodiment, a through hole 32A is formed on the lower end side of the inclined portion 32, penetrating in the up-down direction and through which the first harness 61 passes (see FIG. 6).
[0090] A through hole 32A that penetrates in the up-down direction and through which the first harness 61 passes is formed on the lower end side of the inclined portion 32, so that the first harness 61 is connected to the target component through the through hole 32A provided on the lower end side of the inclined portion 32. Therefore, damage to the first harness 61 is suppressed compared to the case where an opening is provided on the upper end side of the inclined portion 32.
[0091] In the embodiment of the image forming device 10, a third rib 42 is formed above the through hole 32A, protruding toward the upper end side of the inclined portion 32 and having a tapered portion that is inclined in a direction approaching the through hole 32A (see Figure 6).
[0092] Since the third rib 42 is formed above the through hole 32A and has a tapered portion that protrudes toward the upper end side of the inclined portion 32 and inclines in a direction approaching the through hole 32A, when the tip of the first harness 61 slides down the inclined portion 32, the tip of the first harness 61 is guided into the through hole 32A using the third rib 42 as a guide. Therefore, compared to a harness having a third rib 42 that extends horizontally, the workability of inserting the tip of the first harness 61 into the through hole 32A is improved.
[0093] In the embodiment of the image forming apparatus 10, the through hole 32A is formed in a cylindrical body 32B that protrudes downward from the lower surface of the guide component 30, and the cylindrical body 32B penetrates the sheet metal that constitutes the upper surface of the substrate box 24 (see FIG. 6).
[0094] The cylindrical body 32B penetrates the metal plate constituting the upper surface of the board box 24, so that when the first harness 61 is inserted into the through hole 32A, the periphery of the first harness 61 is covered with the cylindrical body 32B. Therefore, the first harness 61 can be connected to the control board 26 without contacting the metal plate.
[0095] In the image forming apparatus 10 of the embodiment, the guide component 30 is formed with a first pressing portion 44 that extends toward the upper end side of the inclined portion 32 and presses the first harness 61 so as to cover the inclined portion 32 (see FIG. 5).
[0096] In the guide component 30, the first pressing portion 44 that extends toward the upper end side of the inclined portion 32 and presses the first harness 61 is formed so as to cover the inclined portion 32, so that the first harness 61 arranged on the inclined portion 32 is sandwiched between the first pressing portion 44 and the inclined portion 32. Therefore, compared to the case where the first harness 61 is bonded to the guide component 30, workability is improved.
[0097] In the image forming apparatus 10 of the embodiment, the inclined portion 32 is provided with a clamp seat 50 that protrudes upward and to which the third harness 63 is clamped (see FIG. 8).
[0098] The inclined portion 32 is provided with a clamp seat 50 that protrudes upward and to which the third harness 63 is attached, so that the first harness 61 placed on the inclined portion 32 is positioned by the clamp seat 50, and the third harness 63 is clamped to the clamp seat 50. Therefore, compared to a case in which a base is placed on the inclined portion 32, the third harness 63 can be placed at a position where the influence of radio waves from the first harness 61 placed on the inclined portion 32 is suppressed.
[0099] As described above, a specific embodiment of the present invention has been described, however, the present invention is not limited to the above embodiment, and various modifications, changes, and improvements are possible within the scope of the technical concept of the present invention.
[0100] In the embodiment, the inclined portion 32 is inclined downward from the outside to the inside of the apparatus. However, the inclined portion may be inclined downward from the right to the left in the apparatus width direction, or may be inclined downward from the left to the right in the apparatus width direction.
[0101] In the embodiment, an example has been shown in which the guide part 30 is provided between the counterbalance 22 and the board box 24 in the vertical direction of the apparatus. However, the guide part may be provided in another location.
[0102] In the embodiment, an example has been shown in which the second harness 62 is arranged along a surface different from the surface of the guide component 30 on which the first harness 61 is arranged. However, the second harness may be arranged along the same surface as the surface of the guide component on which the first harness is arranged.
[0103] In the embodiment, an example has been shown in which the second harness 62 and the first harness 61 are arranged along orthogonal surfaces of the guide component 30. However, the second harness and the first harness may be arranged along non-orthogonal surfaces of the guide component.
[0104] In the embodiment, an example has been shown in which the first rib 41 that protrudes upward and supports the first harness 61 is formed on the lower end side of the inclined portion 32. However, the first rib 41 does not necessarily have to be formed on the lower end side of the inclined portion.
[0105] In the embodiment, an example has been shown in which the second rib 47 that protrudes upward and separates the arrangement space of the first harness 61 is formed on the upper end side of the inclined portion 32. However, the second rib 47 does not necessarily have to be formed on the upper end side of the inclined portion.
[0106] In the embodiment, an example has been shown in which the through hole 32A, which penetrates in the up-down direction and through which the first harness 61 passes, is formed on the lower end side of the inclined portion 32. However, the through hole 32A through which the first harness 61 passes does not necessarily have to be formed on the lower end side of the inclined portion.
[0107] In the embodiment, an example has been shown in which the third rib 42 is formed above the through hole 32A, protruding toward the upper end side of the inclined portion 32 and having a tapered portion inclined in a direction approaching the through hole 32A. However, the third rib 42 does not necessarily have to be formed above the through hole 32A.
[0108] In the embodiment, an example has been shown in which the through hole 32A is formed in the cylindrical body 32B protruding downward from the lower surface of the guide component 30, and the cylindrical body 32B penetrates the metal sheet constituting the upper surface of the board box 24. However, the through hole does not necessarily have to be formed in the cylindrical body 32 protruding downward from the lower surface of the guide component.
[0109] In the embodiment, an example has been shown in which the guide component 30 is formed with the first pressing portion 44 that extends toward the upper end side of the inclined portion 32 and presses the first harness 61 so as to cover the inclined portion 32. However, the guide component does not necessarily have to be formed with the first pressing portion 44.
[0110] In the embodiment, an example has been shown in which the inclined portion 32 is provided with the clamp seat 50 that protrudes upward and clamps the third harness 63. However, the clamp seat 50 does not necessarily have to be formed on the inclined portion.

[0112] According to the image forming apparatus of (((1))), a guide part for supporting a harness is provided between an image reading unit and a board box that is provided below the image reading unit and contains a board, and the guide part has an inclined part that inclines downward on its upper surface, so that when the harness is placed on the upper end side of the inclined part, the harness slides down the inclined part and is placed on the lower end side of the inclined part. Therefore, it is easier for the user to place the harness compared to when the entire guide part that supports the harness and is located between the image reading unit and the board box is a horizontal plane.
[0113] According to the image forming device of (((2))), the inclined portion is inclined downward toward the inside of the device, so that the harness is disposed inside the device. Therefore, damage to the harness is suppressed compared to when the inclined portion is inclined downward toward the outside of the device. Also, since the harness is disposed inside the device, the effect of noise on the harness is reduced compared to when the harness is disposed outside the device.
[0114] According to the image forming apparatus of (((3))), the guide component is disposed between the counterbalance and the board box, Compared to a case in which the inclined portion is positioned offset from the counterbalance, it is easier to position the harness at the desired location by passing it between the counterbalance and the board box.
[0115] According to the image forming device of (((4))), the multiple harnesses are arranged along different faces of the guide component, so that one harness and another harness are arranged separately on different faces. Therefore, the influence of radio waves between the harnesses is reduced compared to when the multiple harnesses are arranged on the same face of the guide component.
[0116] According to the image forming device of (((5))), the one harness and the other harness are arranged along the orthogonal faces of the guide component, so that the one harness and the other harness are arranged perpendicular to each other. Therefore, the influence of radio waves between the harnesses is reduced compared to when the one harness and the other harness are arranged in parallel.
[0117] According to the image forming device of (((6))), a first rib that protrudes upward and supports the harness is formed on the lower end side of the inclined portion, so that the harness comes into contact with the first rib when sliding down the inclined portion. Therefore, the harness can be positioned at a desired position on the inclined portion.
[0118] According to the image forming device of (((7))), a second rib that protrudes upward and divides the space in which the harness is arranged is formed on the upper end side of the inclined portion, making it possible to position the harness arranged on the inclined portion.
[0119] According to the image forming device of (((8))), a through hole that penetrates in the vertical direction and through which the harness passes is formed at the lower end side of the inclined portion, so that the harness passes through the through hole provided at the lower end side of the inclined portion and is connected to the target component. Therefore, damage to the harness is suppressed compared to the case where an opening is provided at the upper end side of the inclined portion.
[0120] According to the image forming device of (((9))), a third rib is formed above the through hole, protruding toward the upper end side of the inclined portion and having a tapered portion inclined toward the through hole, so that when the end of the harness slides down the inclined portion, the end of the harness is guided into the through hole using the third rib as a guide. Therefore, compared to an image forming device having a horizontally extending third rib, the workability of inserting the end of the harness into the through hole is improved.
[0121] According to the image forming apparatus of (((10))), the cylindrical body penetrates the metal sheet that constitutes the upper surface of the base box, so that when the harness is inserted into the through hole, the harness is covered by the cylindrical body. Therefore, the harness can be connected to the board without contacting the metal plate.
[0122] According to the image forming apparatus of (((11))), the guide part has a pressing part that extends toward the upper end side of the inclined part and presses the harness so as to cover the inclined part, so that the harness placed on the inclined part is sandwiched between the pressing part and the inclined part. Therefore, workability is improved compared to when the harness is bonded to the guide part.
[0123] According to the image forming device of (((12))), the inclined portion is provided with a clamp seat that protrudes upward and to which another harness is clamped, so that the harness placed on the inclined portion is positioned by the clamp seat, and the other harness is clamped to the clamp seat. Therefore, compared to a case in which a base is placed on the inclined portion, the other harness can be placed in a position where the influence of radio waves from the harness placed on the inclined portion is suppressed.
