Embodiments for Carrying Out the Invention

[0016] The image forming apparatus 1 according to an embodiment of the present disclosure and the operation panel device 10 as an electronic device included in the image forming apparatus 1 will be described with reference to the drawings.

[0017] (Image forming apparatus) FIG. 1 is an explanatory diagram showing a schematic configuration of an image forming apparatus 1 according to an embodiment. The image forming apparatus 1 has a copying function of reading a document and printing it on paper.

[0018] The image forming apparatus 1 includes an image reading unit 12, a document conveyance unit 13, an image forming unit 14, etc. in the apparatus main body 11. The image reading unit 12 and the document conveyance unit 13 are mounted on the upper part of the apparatus main body 11.

[0019] The document conveyance unit 13 conveys the document to the image reading unit 12. In the image reading unit 12, light is irradiated onto the document, and image data corresponding to the image of the document is generated from the reflected light. The image reading unit 12 has a scanner optical system accommodated below a document table provided with a transparent glass. In the scanner optical system, light is irradiated onto the document on the document table, and an electrical signal corresponding to the reflected light from the document is generated as an image signal.

[0020] The image forming unit 14 includes a primary transfer unit 15, a secondary transfer unit 16, a belt cleaning unit 17, a fixing unit 18, etc., forms a visible image based on image data, and forms an image on a sheet such as a predetermined recording sheet. The image data processed in the image forming apparatus 1 corresponds to a color image using each color of black (K), cyan (C), magenta (M), and yellow (Y), or a monochrome image using a single color (for example, black). The image forming unit 14 is provided with four photosensitive drums 21 that act as image carriers, and each is equipped with a charging device, an exposure device, a developing device, and a photosensitive cleaning device (not shown) to form four types of toner images corresponding to each color of black, cyan, magenta, and yellow.

[0021] The primary transfer unit 15 has four photosensitive drums 21 and an intermediate transfer belt 22 that abuts against the photosensitive drums 21. The intermediate transfer belt 22 is an image carrier on which a toner image is formed, and is stretched between a transfer driving roller 23 and a transfer driven roller 24 and moves in a circular motion. By transferring and overlapping the toner images of each color formed on the surface of the photosensitive drum 21, a color toner image is formed on the surface of the intermediate transfer belt 22.

[0022] The transfer roller 25 provided in the secondary transfer unit 16 forms a nip portion with the intermediate transfer belt 22, and sandwiches and conveys the sheet conveyed through the conveyance path 201 in the nip portion. When the sheet passes through the nip portion, the toner image on the surface of the intermediate transfer belt 22 is transferred to the sheet.

[0023] The toner and the like remaining on the intermediate transfer belt 22 are collected by the belt cleaning unit 17. In the fixing unit 18, the sheet with the unfixed toner image transferred thereon is sandwiched between a heating roller 26 and a pressure roller 27 and conveyed while being heated and pressurized to thermally fix the unfixed toner image on the sheet.

[0024] The paper feeding device 19 supplies sheets of paper one by one to the image forming unit 14 with either the paper cassette 29 or the manual feed tray 30 as the paper feeding source. The paper cassette 29 is provided below the image forming unit 14 and stores the paper used for image formation. The paper is pulled out from the paper cassette 29 by the pickup roller 41, conveyed through the conveyance path 201, and carried out to the discharge tray 28 via the secondary transfer unit 16 and the fixing unit 18.

[0025] The manual feed tray 30 is provided on the side surface of the apparatus main body 11 so as to be openable and closable, and is a tray on which the paper used for image formation can be placed. The paper placed on the manual feed tray 30 is pulled out by the paper feed roller 31, guided to the conveyance path 201 via the horizontal conveyance path 202, and conveyed to the image forming unit 14.

[0026] On the conveyance path 201, roller pairs such as the registration roller 42, the conveyance roller 43, and the paper discharge roller 44 are arranged. The registration roller 42 temporarily stops the paper, aligns the leading edges of the paper, and then starts the conveyance of the paper in accordance with the transfer timing at the nip portion between the intermediate transfer belt 22 and the transfer roller 25. The conveyance roller 43 and the paper discharge roller 44 promote the conveyance of the paper.

[0027] When performing image formation not only on the front surface but also on the back surface of the paper, the paper is conveyed from the paper discharge roller 44 to the reverse conveyance path 203, the front and back surfaces of the paper are reversed, and then guided to the registration roller 42, and image formation is performed on the back surface in the same manner as on the front surface.

[0028] (Electronic device) As an embodiment of the electronic device according to the present disclosure, the operation panel device 10 provided in the image forming apparatus 1 will be described in detail.

[0029] The electronic device according to the present disclosure includes an electrical member having a flat cable and a substrate to which the flat cable is connected. Between the electrical member and the substrate, a holder member is provided which is arranged to face the substrate and holds the electrical member, and the holder member includes a positioning portion that serves as a wiring path for the flat cable. The flat cable is configured to be connected to a connector provided on the substrate through the positioning portion.

[0030] In the image forming apparatus 1, an operation panel device 10 is provided to receive various image forming conditions from the user, such as the number of images to be formed and the size of the image or paper. In an exemplary form, the operation panel device 10 as an electronic device provided in the image forming apparatus 1 is provided adjacent to the image reading unit 12.

[0031] As shown in FIG. 1, the operation panel device 10 is provided on the front side of the apparatus main body 11, offset to one side in the left - right direction (the width direction of the image reading unit 12), in front of the image reading unit 12 provided on the upper surface of the apparatus main body 11. Note that the operation panel device 10 is provided on the front side of the apparatus main body 11 assuming that the user who operates it stands in front of the image reading unit 12, and is not limited to this arrangement.

[0032] (Embodiment 1) FIGS. 2 and 3 are cross - sectional views schematically showing the internal structure of the operation panel device 10, FIG. 2 is a cross - sectional view, and FIG. 3 is a longitudinal cross - sectional view.

[0033] The operation panel device 10 includes a touch panel 101, a display unit 102 having a flat cable 70 of a predetermined length, and a substrate 103. The flat cable 70 is connected to a connector 104 provided on the substrate 103, which will be described later. Note that as the flat cable 70, a flexible flat cable having a flat surface using a flexible film can be exemplified.

[0034] The touch panel 101, the display unit 102, and the substrate 103 are housed inside the housing 50 of the operation panel device 10. As shown in FIGS. 2 and 3, the operation panel device 10 according to the exemplary embodiment includes an upper cabinet 51 and a lower cabinet 52 as the housing 50, and the touch panel 101, the display unit 102, and the substrate 103 are housed in the internal space formed by fitting these together. The lower cabinet 52 may be coupled to a rotation axis (not shown) and rotatably fixed to the apparatus main body 11 of the image forming apparatus 1.

[0035] The upper cabinet 51 is provided with an opening that penetrates inside and outside. The edge of the opening is preferably surrounded by a filter. The touch panel 101 is arranged along the upper cabinet 51 and is provided so as to be exposed at the opening of the upper cabinet 51, enabling a touch operation on the touch panel 101.

[0036] The touch panel 101 is, for example, an analog resistive film type touch panel, which is provided on the display unit 102 and is used to detect an input with respect to the position displayed on the display unit 102. The display unit 102 is an electrical member that provides information to the user, and for example, a flat panel display device such as a liquid crystal display or an EL display is used. Note that the touch panel 101 is not limited to the analog resistive film method using voltage division, and may be a capacitance method that detects a change in capacitance with a finger, an infrared light blocking method that uses a blocked portion of irradiated infrared light, or a camera method that identifies a position by the shadow of the photographed finger.

[0037] These touch panel 101 and display unit 102 are arranged between the holder member 60 and the upper cabinet 51. When the side where the touch panel 101 is provided in the operation panel device 10 is defined as the front side X1, the display unit 102 is arranged on the front side X1 of the holder member 60. In addition, the operation panel device 10 may be provided with an operation area having various keys.

[0038] The substrate 103 is disposed on the back surface side X2, which is opposite to the front surface side X1 of the holder member 60, and includes a connector 104 to which one end of the flat cable 70 is connected. The other end of the flat cable 70 passes through the lower cabinet 52 and is electrically connected to a main body substrate (not shown) of the apparatus main body 11. The operation panel device 10 is configured to be able to transmit signals to and from the apparatus main body 11 via the flat cable 70.

[0039] A holder member 60 for holding the display unit 102 is provided between the display unit 102 as an electrical member and the substrate 103. The holder member 60 is disposed to face the substrate 103, and the display unit 102 is disposed on the side opposite to the substrate 103. The holder member 60 has a substantially rectangular planar shape. For example, an edge projects from the outer peripheral portion, and it is formed in a substantially box shape capable of accommodating the display unit 102 inside.

[0040] FIG. 4 is a plan view schematically showing the back surface side X2 of the holder member 60. As shown in the drawing, on the back surface of the holder member 60, the substrate 103 is disposed so as to face the back surface of the holder member 60. The substrate 103 is provided with a connector 104 and an LED mounting region 105. The flat cable 70 introduced into the operation panel device 10 takes a wiring path within the operation panel device 10 and is connected to the connector 104 of the substrate 103. The portion where the display unit 102 is held is formed to be convex (concave on the front surface side X1) on the back surface side X2 of the holder member 60.

[0041] A positioning portion 61 serving as a wiring path for the flat cable 70 is provided on the surface X1 of the holder member 60. The positioning portion 61 includes a plurality of wiring openings allowing insertion of the flat cable 70 and a groove-shaped recess 63 for arranging the flat cable 70. The flat cable 70 is wired through the positioning portion 61, and its wiring path is secured on the holder member 60.

[0042] In the example shown in FIG. 4, a first wiring port 621 and a second wiring port 622 are provided at positions separated from each other on the holder member 60. The first wiring port 621 and the second wiring port 622 penetrate and open on both the front and back surfaces of the holder member 60, and the flat cable 70 is inserted therethrough.

[0043] The first wiring port 621 is opened above the outer peripheral portion of the substrate 103, and the second wiring port 622 is opened on the side of the outer peripheral portion of the substrate 103, in the vicinity of the connector 104. The flat cable 70 is wired by being inserted from the back surface side X2 to the front surface side X1 through the first wiring port 621. Further, the flat cable 70 is drawn out from the front surface region 601 of the holder member 60, through the second wiring port 622, to the back surface region 602 of the holder member 60 and is connected to the connector 104.

[0044] FIG. 5 is a perspective view schematically showing the front surface region 601 on the front surface of the holder member 60 where the display unit 102 is disposed. In FIG. 5, only the front surface region 601 of the holder member 60 is shown, and illustration of other regions is omitted.

[0045] As shown in FIG. 4, the display unit 102 is disposed to face, abut on, or be close to the front surface region 601 provided on the opposite side of the back surface region 602 of the holder member 60. As shown in FIG. 5, the recess 63 of the holder member 60 is provided in the front surface region 601 which is the surface facing the display unit 102 in the holder member 60.

[0046] The recess 63 is provided in a groove shape along the planar direction of the front surface region 601, and the groove depth and the groove width correspond to the thickness of the flat cable 70 and are formed in a size capable of storing the flat cable 70. The first wiring port 621 is disposed at one end of the recess 63, and the second wiring port 622 is disposed at the other end of the recess 63.

[0047] In an exemplary embodiment, the recess 63 has a corner portion 64 for bending and wiring the flat cable 70. The corner portion 64 is formed corresponding to the shape when the flat cable 70 is bent, and is formed, for example, in a groove shape forming an angle of about 45° with respect to the recess 63.

[0048] The flat cable 70 disposed in the recess 63 of the positioning portion 61 through the first wiring port 621 is bent in a substantially right angle direction at the position of the corner portion 64 and disposed to form a substantially L shape. As shown in FIG. 4, it is drawn out to the back surface area 602 on the opposite side of the front surface area 601 through the second wiring port 622. The flat cable 70 guided to the back surface area 602 of the holder member 60 through the second wiring port 622 is folded in half and connected to a connector 104 provided on the substrate 103.

[0049] In this way, the flat cable 70 is disposed in the positioning portion 61 of the holder member 60, takes a wiring path between the front surface area 601 of the holder member 60 and the display portion 102, and is stored and protected in the recess 63. Therefore, it is not necessary to provide a separate cover member or protection member dedicated to the flat cable, and moreover, it is possible to suppress the generation of load on the flat cable 70. Note that the flat cable 70 may be fixed to the recess 63 of the positioning portion 61 with an adhesive tape or the like, and the load can be further suppressed.

[0050] (Embodiment 2) In addition to the configuration shown in Embodiment 1, the operation panel device 10 of the present disclosure can be implemented with various configurations. For example, the positioning portion 61 of the flat cable 70 provided on the holder member 60 of the operation panel device 10 is not limited to the above configuration, and can be configured in various ways as shown below.

[0051] FIG. 6 is a perspective view schematically showing the front surface area 601 of the holder member 60 in the operation panel device 10 according to Embodiment 2, and FIG. 7 is a cross-sectional view taken along line A-A in FIG. 6. FIG. 8 is a perspective view schematically showing another example of the front surface area 601 of the holder member 60 in the operation panel device 10 according to Embodiment 2.

[0052] As shown in FIG. 6, the positioning portion 61 provided in the holder member 60 may have a slit 65 formed in the recess 63. The slit 65 is provided in an elongated rectangular shape along the width direction of the recess 63 and is formed to penetrate the recess 63 in the front surface region 601 and the back surface region 602.

[0053] In the exemplary form, a first wiring port 621 is disposed at one end of the first recess 631, and a slit 65 is disposed at the other end of the recess 63. The first recess 631 is provided to be connected to the first wiring port 621. The recess 63 is provided on the extension line of the first recess 631 with the flat portion of the front surface region 601 interposed therebetween. The recess as the positioning portion 61 includes the first recess 631 and the recess 63. A slit 65 is also provided at one end of the recess 63, and a second wiring port 622 is disposed at the other end of the recess 63.

[0054] In this case, the flat cable 70 disposed in the positioning portion 61 through the first wiring port 621 is drawn out from the first recess 631 through the slit 65 into the back surface region 602 once, and then drawn out from the back surface region 602 through the slit 65 again and disposed in the recess 63. In the recess 63, it is bent in a substantially right angle direction at the position of the corner portion 64 and disposed so as to form a substantially L shape, and is drawn out to the back surface region 602 through the second wiring port 622 and connected to the connector 104 provided on the substrate 103.

[0055] As shown in FIG. 7, in the back surface region 602, a back surface recess 633, which is a groove-shaped recess, is provided in a portion located between one slit 65 and the other slit 65. On the back surface side of the holder member 60, the flat cable 70 is disposed through the back surface recess 633.

[0056] The overlapping distance D in the thickness direction (the direction along the X1 direction and the X2 direction) between the first concave portion 631 and the back surface concave portion 633 is preferably less than the thickness of the flat cable 70. For example, when the thickness of the flat cable 70 is 0.3 mm, the overlapping distance D is preferably set within a range less than 0.3 mm. Thereby, the flat cable 70 inserted through the slit 65 can be stably held. Note that the first concave portion 631 and the back surface concave portion 633 may be continuous in the thickness direction and communicate with each other at the groove bottom without having the overlapping distance D. The width W of the slit 65 may be equal to or greater than the thickness of the flat cable 70.

[0057] By arranging the flat cable 70 to pass through the two slits 65 in this way, the flat cable 70 can be stably arranged in the positioning portion 61. Since the flat cable 70 is held in a sandwiched state by being inserted into the slit 65, the movement of the flat cable 70 is restricted, and it is difficult to be pulled out even when a tensile force acts. Therefore, damage to the flat cable 70 and breakage of the connector 104 due to pulling out of the flat cable 70 can be prevented.

[0058] Also, as shown in FIG. 8, a pressing portion 66 may be provided between one slit 65 and the other slit 65. One end of the pressing portion 66 in the width direction is continuously provided to the surface region 601, and the other end is separated from the surface region 601 and formed in a cantilever shape. The pressing portion 66 functions to press the flat cable 70 inserted through the two slits 65 from the surface side X1, restricts the movement of the flat cable 70, and makes it difficult to be pulled out even when a tensile force acts.

[0059] (Embodiment 3) FIG. 9 is a plan view schematically showing the surface region 601 of the holder member 60 in the operation panel device 10 according to Embodiment 3, and FIG. 10 is a plan view schematically showing another example of the surface region 601 of the holder member 60 in the operation panel device 10 according to Embodiment 3.

[0060] As the positioning portion 61, the slit 65 provided to penetrate the concave portion 63 of the front surface region 601 and the back surface region 602 may be provided near the corner portion 64. In the example shown in FIG. 9, two slits 65 are disposed between the corner portion 64 and the second wiring port 622. As the groove-shaped concave portion, a first concave portion 631 provided between the first wiring port 621 and one slit 65 and a second concave portion 632 provided between the other slit 65 and the second wiring port 622 are provided.

[0061] In this case, the flat cable 70 disposed in the positioning portion 61 through the first wiring port 621 is disposed in the first concave portion 631, bent at the corner portion 64, and once drawn out to the back surface region 602 through the slit 65 provided at the end of the first concave portion 631. From the back surface region 602, the flat cable 70 is drawn out to the front surface region 601 again through the slit 65, disposed in the second concave portion 632, drawn out to the back surface region 602 through the second wiring port 622, and connected to the connector 104 provided on the substrate 103.

[0062] Even in this form, by arranging the flat cable 70 to pass through the two slits 65, the flat cable 70 can be stably arranged in the positioning portion 61. Since the flat cable 70 is sandwiched and held by being inserted into the slit 65, the movement of the flat cable 70 is restricted, and it is difficult to be pulled out even when a tensile force acts. Therefore, damage to the flat cable 70 and damage to the connector 104 due to pulling out of the flat cable 70 can be prevented.

[0063] Also, as shown in FIG. 10, in the second recess 632, a lid portion 67 may be provided to sandwich the flat cable 70 between the surface side X1 and the second recess 632. The lid portion 67 is a plate-like member having a shape that fits into the second recess 632. Since the flat cable 70 drawn out to the back surface region 602 through the second wiring opening 622 is folded back toward the substrate 103 side, it tends to bulge before and after the second wiring opening 622. Therefore, a lid portion 67 may be provided in the second recess 632 of the positioning portion 61 so as to hold down the flat cable 70 that tends to bulge. Thereby, the flat cable 70 can be arranged more stably, and damage and breakage can be suppressed.

[0064] (Embodiment 4) FIG. 11 is a perspective view schematically showing the back surface region 602 of the holder member 60 in the operation panel device 10 according to Embodiment 4, and FIG. 12 is a longitudinal sectional view of the operation panel device 10 according to Embodiment 4.

[0065] As shown in the drawing, the positioning portion 61 may be provided in the back surface region 602 which is the surface of the holder member 60 facing the substrate 103. Even when the positioning portion 61 is provided in the back surface region 602 of the holder member 60, it is preferable that the positioning portion 61 includes a first wiring opening 621, a recess 63, a corner portion 64, and a second wiring opening 622. Further, a slit 65 may be provided in the vicinity of the first wiring opening 621 in the recess 63, and another slit 65 may be provided in the vicinity of the second wiring opening 622.

[0066] The flat cable 70 is once led from the back surface region 602 through the first wiring opening 621 to the front surface region 601, inserted through the slit 65, and arranged in the recess 63. In the recess 63, it is bent at the corner portion 64, inserted through the slit 65 before reaching the second wiring opening 622, drawn out to the front surface region 601, led from the second wiring opening 622 to the back surface region 602, and connected to the connector 104 of the substrate 103.

[0067] As shown in FIG. 12, the flat cable 70 disposed in the positioning portion 61 is held between the substrate 103 and the holder member 60 on the back surface side X2 of the holder member 60. Also in this case, the flat cable 70 is disposed in the recess 63 by passing through a plurality of slits 65, so that the movement of the flat cable 70 is restricted and it is difficult to be pulled out even when a tensile force acts thereon. Therefore, damage to the flat cable 70 and breakage of the connector 104 due to pulling out of the flat cable 70 can be prevented.

[0068] (Embodiment 5) FIG. 13 is a longitudinal sectional view showing the operation panel device 10 according to Embodiment 5, and FIG. 14 is a longitudinal sectional view showing another example of the operation panel device 10 according to Embodiment 5.

[0069] In the operation panel device 10, the holder member 60 may be provided integrally with the upper cabinet of the housing 50. For example, as shown in FIG. 13, when a wiring path for the flat cable 70 is provided on the front surface side X1 of the holder member 60, a continuous portion 603 having the shape of an upper cabinet may be provided at the edge of the holder member 60 so as to fit into the lower cabinet 52. A filter 53 is provided on the outer peripheral portion of the touch panel 101. Also, as shown in FIG. 14, when a wiring path for the flat cable 70 is provided on the back surface side X2 of the holder member 60, a continuous portion 603 having the shape of an upper cabinet may be provided at the edge of the holder member 60 so as to fit into the lower cabinet 52. Thereby, the number of parts can be reduced, and the component parts can be provided in a more space-saving manner.

[0070] As described above, in any of the embodiments of the present disclosure, the flat cable 70 connected to the operation panel device 10 can be stably arranged, and it is possible to suppress the load on the flat cable 70 without providing a dedicated cover member or protection member for the flat cable 70. Thereby, the operation panel device 10 can be configured to be more compact, and the product reliability can also be enhanced.

[0071] In the embodiment of the present disclosure, an example in which the operation panel device 10 as an electronic device is provided in the image forming apparatus 1 has been described.
