DETAILED DESCRIPTION

[0064] Next, the present invention will be described in further detail below with reference to the drawings by way of embodiments and specific examples, but the present invention is not limited to these embodiments and specific examples.

[0065] In the following description using the drawings, it should be noted that the drawings are schematic, ratios of dimensions and the like are different from those in reality, and that components other than those necessary for the description are omitted as appropriate for ease of understanding.

[0066] (1) Overall Structure and Operation of Image Forming Apparatus

[0067] Figure 1 It is a schematic cross-sectional view showing an example of a schematic configuration of the image forming apparatus 1 according to the present embodiment.

[0068] An image forming apparatus 1 as an example of an electronic device is configured to include: an image forming unit 10; a paper feeding device 20 installed at the bottom of the image forming unit 10; a paper discharge unit 30 provided at one end of the image forming unit 10 and discharging printed paper; and an image processing unit 40 (not shown) that generates image information from print information sent from a host device.

[0069] The image forming unit 10 is configured to include: an exposure device 12, a photosensitive unit 13, a developing device 14, a transfer device 15, a paper conveying device 16a, and a fixing device 17, and forms the image information received from the image processing unit 40 as a toner image on the paper P fed from the paper feeding device 20.

[0070] A paper supply device 20 having paper trays 21 and 22 is provided at the bottom of the image forming unit 10 to supply paper to the image forming unit 10. That is, a plurality of paper loading sections for accommodating paper P of different types (e.g., material or thickness, paper size, paper grain) are provided, and the paper P drawn from any of the plurality of paper loading sections is supplied to the image forming unit 10. The paper trays 21 and 22 can be drawn out toward the operator side (-Y direction) and can be drawn out toward the operator side to replenish the paper P.

[0071] The paper discharge unit 30 discharges the paper P on which the image is outputted in the image forming unit 10. Therefore, the paper discharge unit 30 includes a paper discharge storage unit (not shown) into which the paper P after the image is outputted is discharged. In addition, the paper discharge unit 30 includes a paper conveying device 16c which reverses the front and back sides of the paper P and delivers the paper to the paper conveying device 16b when the image is outputted on both sides of the paper P.

[0072] In addition, the paper discharge unit 30 may have a function of performing post-processing such as cutting or stapling on a bundle of paper sheets discharged from the image forming unit 10 .

[0073] A draw-out unit 18 ( 18 ) as an example of a movable member is provided at the lower portion of the image forming unit 10 so as to be drawable relative to the apparatus main body 11 . Figure 1 Indicated by dotted line).

[0074] The lead-out unit 18 accommodates the paper supply section 26 that sends the arranged paper P toward the transfer device 15, the secondary transfer section 52 that secondary transfers the colorant image on the intermediate transfer belt 51 onto the paper P, the paper conveying device 16a that conveys the paper P toward the fixing device 17, the paper conveying device 16b that conveys the paper P reversed for double-sided printing toward the paper supply section 26, the fixing device 17, etc., and is capable of handling paper jams during image formation by leading it toward the operator side.

[0077] Hereinafter, the configuration and operation of the wire harness connection structure 100 according to the present embodiment will be described with reference to the drawings.

[0078] (2.1) Composition of wiring harness connection structure

[0079] The image forming apparatus 1 as an example of an electronic device includes a lead-out unit 18 as an example of a movable member. Figure 2 As shown, the lead-out unit 18 is provided in a manner that it can be led out via the rail RL relative to the device body 11, and is configured so that by leading the lead-out unit 18 toward the operator side, the paper supply unit 26 can pass through the transfer device 15, the paper conveying device 16a, and finally the fixing device 17 (refer to Figure 1) or regular maintenance or replacement of the secondary transfer unit 52 and the fixing device 17. In addition, the paper conveying path of the paper conveying device 16b for double-sided printing can be opened when the draw-out unit 18 is drawn out (see Figure 5 (b)).

[0080] It is stipulated by law that such a lead unit 18 should be reliably grounded in order to protect the operator from the danger of electric shock when AC power is used in the fixing device 17 or the like.

[0081] In the image forming apparatus 1 of the present embodiment, reliable grounding is achieved by connecting the lead-out unit 18 and the apparatus main body 11 by wires using the wire harness 130 .

[0082] like Figure 2 , Figure 3 (a) and Figure 3 As shown in (b) of FIG. 1 , the lead unit 18 and the device body 11 are connected by wires via a wire harness 130 (indicated by a thick line in the figure).

[0083] One end 130a of the wiring harness 130 is fixed to the front side (the most front side in the present embodiment) of the lead-out direction (-Y direction) of the lead-out unit 18 on a side of the device body 11, i.e., the bottom surface 11a, which is opposite to a side of the lead-out unit 18 with a gap, and the other end 130b is fixed to the inner surface 18b of the lead-out unit 18 in the lead-out direction (-Y direction) of the lead-out unit 18, and the device body 11 and the lead-out unit 18 are electrically connected.

[0084] In addition, as the wire harness 130 , the thickness can be selected from, for example, the AWG (American Wire Gauge) order according to the AC power supplied to the fixing device 17 and the like accommodated in the lead-out unit 18 .

[0085] Here, the front side refers to the lead-out direction side of the midpoint in the depth direction of the bottom surface 11a of the device body 11. It is not limited to the surface of the bottom surface 11a, and also includes a frame surface that descends in the vertical direction from the front side of the bottom surface 11a.

[0086] A first restricting portion 110 is disposed on the bottom surface 11 a of the device body 11 , and restricts movement of the wire harness 130 toward the lead-out side (−Y direction) of the lead-out unit 18 .

[0087] like Figure 2 As shown, the first restricting portion 110 is cylindrical, and the harness 130 having one end 130 a fixed to the bottom surface 11 a of the device body 11 is wound around the first restricting portion 110 and the other end 130 b is fixed to the inner surface 18 b of the lead-out unit 18 .

[0088] Here, the inner side refers to the side opposite to the lead-out side (-Y direction) of the lead-out unit 18 and the side opposite to the lead-out side relative to the midpoint in the depth direction of the lead-out unit 18. In addition, the location where the other end 130b is fixed is not limited to the surface 18b, but may be a location on the inner side corresponding to the lower surface 18a of the lead-out unit 18.

[0089] On the bottom surface 11 a of the device body 11 , a second restricting portion 120 which is a plate-like member is arranged so as to extend from above the first restricting portion 110 in the draw-out direction of the draw-out unit 18 .

[0090] The second limiting part 120 is fixed to the first limiting part 110 in a manner that the front side 120a in the lead-out direction of the lead-out unit 18 covers the first limiting part 110, and the other end side 120b is fixed in a manner that the other end side 120b is inserted into the frame 11b on the inner side of the device body 11. Figure 3 As shown in (b), the second limiting portion 120 is arranged in a gap G between the bottom surface 11a of the device body 11 and the lower surface 18a of the lead-out unit 18, and limits the movement of the wiring harness 130 in a direction approaching the lead-out unit 18 between one side of the lead-out unit 18, i.e., the lower surface 18a, and the bottom surface 11a of the device body 11.

[0091] like Figure 2 , Figure 3 (a) and Figure 3 As shown in (b), the first limiting portion 110 is provided in a moving range L (reference Figure 3 (b)) is divided into two equal parts in the middle.

[0092] Furthermore, when observing the configuration position of the first limiting portion 110 from the perspective of the length of the wire harness 130, the first limiting portion 110 is provided at an intermediate position between the accommodated position and the lead-out position so that the length from the first limiting portion 110 when the lead-out unit 18 is located at the accommodated position accommodated in the device body 11 to the fixed position where the other end 130b of the wire harness 130 is fixed on the lead-out unit 18 is approximately equal to the length of the wire harness 130 from the first limiting portion 110 to the fixed position when the lead-out unit 18 is located at the lead-out position where the lead-out unit 18 is led out from the device body 11.

[0093] Thus, when the lead unit 18 is led out or stored, the wire harness 130 does not protrude in a direction intersecting the lead-out direction, and can be prevented from coming into contact with other parts.

[0094] And, if Figure 3As shown in (a), when the first limiting portion 110 is viewed from above, the fixing position of one end 130a of the wire harness 130 to the device body 11 and the fixing position of the other end 130b of the wire harness 130 to the lead-out unit 18 are arranged at positions that do not overlap with the arrangement position of the first limiting portion 110 in a direction intersecting the lead-out direction of the lead-out unit 18 ( Figure 3 More specifically, when viewed from the lead-out direction of the lead-out unit 18, the first limiting portion 110 is located between a fixed position of one end 130a of the wire harness 130 to the device body 11 and a fixed position of the other end 130b of the wire harness 130 to the lead-out unit 18.

[0095] This can suppress damage to the wire harness 130 caused by bending at a steep angle due to inherent hardness, twisting, or distortion of the wire harness 130 , and can reliably restrict one side of the lead-out direction of the wire harness 130 by the first restriction portion 110 when the lead-out unit 18 is led out.

[0096] (2.2) Operation of the wiring harness connection structure

[0097] like Figure 4 (a) and Figure 4 As shown in (b), when the lead-out unit 18 is located in the accommodation position relative to the device body 11, the wiring harness 130 is in a state where one end 130a is fixed to the frontmost side of the lead-out direction (-Y direction) of the lead-out unit 18 on the bottom surface 11a of the device body 11 and the other end 130b is moved to the accommodation position together with the lead-out unit 18.

[0098] In this state, the wire harness 130 has a surplus length (L+α) between the one end 130 a and the other end 130 b in a state where the lead-out unit 18 is located at the storage position stored in the device body 11 .

[0099] This improves the durability of the wire harness 130. Furthermore, the wire harness 130 is restricted from moving toward the lead-out unit 18 by the second restriction portion 120, thereby preventing the lead-out unit 18 from contacting the wire harness 130 while moving with a narrow gap when the lead-out unit 18 moves from the lead-out position to the storage position.

[0100] like Figure 5 (a) and Figure 5As shown in (b), when the lead-out unit 18 is located at the lead-out position relative to the device body 11, the wire harness 130 is in a state where one end 130a is fixed to the frontmost side of the lead-out direction (-Y direction) of the lead-out unit 18 of the bottom surface 11a of the device body 11 and is wound around the first limiting portion 110, and the other end 130b moves to the lead-out position together with the lead-out unit 18. In addition, in the first limiting portion 110, the wire harness 130 does not detach from the first limiting portion 110 while being restricted from moving upward by the second limiting portion 120 and being wound around the first limiting portion 110.

[0101] In addition, the draw-out unit 18 opens the lower surface 18b at the draw-out position, thereby enabling paper jam removal in the paper conveying device 16b during double-sided printing (see FIG. 14 ). Figure 5 (b)).

[0102] Thus, the length of the wire harness 130 is substantially the same from the position of the first limiting portion 110 to the fixed position of the lead-out unit 18, regardless of whether the lead-out unit 18 is in the storage position or in the lead-out position (see FIG. Figure 4 L1 in (a), Figure 5 In (a) L2), when the lead-out unit 18 is led out or accommodated, the wire harness 130 does not extend in a direction intersecting the lead-out direction (loosen and greatly bulge) and is prevented from contacting other parts.

Figure 8 (b) is a schematic side view showing the wire harness connection structure according to the first modification in a state where the lead-out unit 18 is led out.

[0105] like Figure 6As shown, one end 120Aa of the second limiting portion 120A is fixed to one side end portion in the lead-out direction of the lead-out unit 18 in one side of the device body 11, i.e., the bottom surface 11a, and the other end 120Ab is fixed to the other side end portion on the opposite side to the lead-out direction of the one side end portion, and is arranged on the bottom surface 11a of the device body 11 as a plate-like component extending in the lead-out direction (Y direction) of the lead-out unit 18 to the accommodation position of the lead-out unit 18 of the device body 11.

[0106] like Figure 7 As shown in (b), the second limiting portion 120A is arranged in the gap G between the bottom surface 11a of the device body 11 and the lower surface 18b of the lead-out unit 18, and limits the movement of the wiring harness 130 in the direction approaching the lead-out unit 18 between one side of the lead-out unit 18, i.e., the lower surface 18b, and one side of the device body 11, i.e., the bottom surface 11a.

[0107] Regarding the first limiting portion 110A, the first limiting portion 110A is protrudingly formed on one side of the second limiting portion 120A facing the device body 11, that is, the bottom surface 11a, in a manner intersecting (orthogonal) with the extraction direction of the extraction unit 18, at a middle position that divides the length direction (Y direction) of the second limiting portion 120A into two equal parts in the extraction direction (Y direction) of the extraction unit 18. In this modified example, the first limiting portion 110A and the second limiting portion 120A may also be formed as one piece.

[0108] In this case, the other end 120Ab of the second limiting portion 120A is inserted into the frame 11b on the inner side of the device body 11, and one end 120Aa of the second limiting portion 120A is screwed to the frontmost side in the lead-out direction of the lead-out unit 18 on the bottom surface 11a of the device body 11, thereby improving the assembly performance compared to the second limiting portion 120 in the above-mentioned embodiment.

[0109] Thus, when the lead-out unit 18 is moved to the storage position while maintaining a narrow gap relative to the device body 11, the wire harness 130 is prevented from contacting the lead-out unit 18, and when the lead-out unit 18 is pulled out and when the lead-out unit 18 is stored, the wire harness 130 does not extend in a direction intersecting the lead-out direction, thereby preventing contact with other parts.

[0110] [Modifications]

[0111] Fig. 9 is a perspective view showing the wire harness connection structure according to the second modification in a state where the lead-out unit 18A is led out. Fig.10 (a) is a schematic top view showing the wiring harness connection structure in a state where the lead-out unit 18A is accommodated, Fig.10 (b) is a side view schematic diagram showing the wiring harness connection structure in a state where the lead-out unit 18A is accommodated, Fig.11 (a) is a schematic top view showing the wiring harness connection structure in a state where the lead-out unit 18A is led out, Fig.11 (b) is a side schematic diagram showing the wire harness connection structure in a state where the lead-out unit 18A is led out.

[0112] A first restriction portion 110B is disposed on the left side surface 11 c of the apparatus body 11 to restrict movement of the wire harness 130 to the lead-out side (−Y direction) of the lead-out unit 18A.

[0113] like Fig. 9 As shown, the first restricting portion 110 is cylindrical, and the harness 130 having one end 130a fixed to the left side 11c of the device body 11 is wound around the first restricting portion 110B and the other end 130b is fixed to the back side of the left side 18c of the lead-out unit 18A.

[0114] On the left side surface 11 c of the apparatus body 11 , a second restricting portion 120B is disposed as a plate-like member extending from above the first restricting portion 110 in the draw-out direction of the draw-out unit 18A.

[0115] The second limiting portion 120B is fixed to the first limiting portion 110B in such a manner that the front side of the lead-out unit 18A in the lead-out direction covers the first limiting portion 110B from the side, and the other end side is fixed in such a manner that it is inserted into the frame 11b on the inner side of the device body 11.

[0116] like Fig.10 As shown in (a), the second limiting portion 120B is arranged in a gap G between the left side surface 11c of the device body 11 and the left side surface 18c of the lead-out unit 18A, and limits the movement of the wiring harness 130 between one side of the lead-out unit 18A, i.e., the left side surface 18c, and one side of the device body 11, i.e., the left side surface 11c, toward the direction approaching the lead-out unit 18.

[0117] Thus, when the lead-out unit 18A is moved to the storage position while maintaining a narrow gap relative to the left side surface 11c of the device body 11, the wiring harness 130 is prevented from contacting the lead-out unit 18A, and when the lead-out unit 18A is pulled out and when the lead-out unit 18A is stored, the wiring harness 130 does not extend in a direction intersecting the lead-out direction, thereby preventing contact with other parts.

[0118] In this embodiment, as an example of a movable part, a wiring harness connection structure between the lead-out unit 18, 18A which accommodates the fixing device 17 and the like and the device body 11 is described, but the movable part is not limited to the lead-out unit 18, 18A, and may also be a paper tray 21, 22 of a paper feeding device 20 having a motor as a driving source of the paper feeding mechanism.

[0119] Furthermore, electronic devices to which the harness connection structure according to the present invention is applicable are not limited to image forming devices, and include electronic devices using electronic components utilizing AC power, such as image reading devices, image processing devices, and personal computers.
