Each of the exposure devices 32 irradiates the outer peripheral surface of the photoconductor 28 charged by the charging device 30 with exposure light corresponding to the image data of each color, and irradiates the outer peripheral surface of each photoconductor 28 with the image data of each color. Latent image is formed.

  Further, the latent images formed on the outer peripheral surface of each photoconductor 28 are developed by each developing device 34 as toner images of each color. That is, each developing device 34 develops the latent image formed on the outer peripheral surface of each photoconductor 28 as a toner image, and each photoconductor 28 holds the toner image developed by the developing device 34 on its outer peripheral surface. It has become.

<Connector holding member>
Next, the connector holding member 50 provided in the apparatus main body 11 of the image forming apparatus 10 configured as described above will be described in detail.

  As shown in FIG. 1, the connector holding member 50 is disposed, for example, on the back side and below the inside of the apparatus main body 11. The relay connector 64 on the apparatus side (for example, wiring extending from a motor or the like for driving the manual feed tray) is held, and their positions are determined.

  That is, as shown in FIG. 6, for example, the connector holding member 50 holds the relay connector 62 on the power supply side and the relay connector 64 on the device side in a state where they are connected to each other. 4 and 5 show a part of the relay connector 62 on the power supply side and the relay connector 64 on the device side.

  Further, in the following, the relay connector 64 inserted into one of the openings (extending in the vertical direction) of the common opening 54 described later is referred to as a first connector 66 (see FIG. 4), and the other (in the vertical and horizontal directions). The relay connector 64 inserted into the opening 58 (which extends obliquely to the direction) is a second connector 68 (see FIG. 5).

  Further, the relay connector 64 inserted into an independent opening 60 described later (see FIGS. 2 and 3) is referred to as an independent connector 70. Further, the image forming apparatus 10 described with reference to FIGS. 1 to 5 and 7 includes one of the first connector 66 and the second connector 68 and the independent connector 70. That is, the image forming apparatus 10 described with reference to FIGS. 1 to 5 and 7 is provided with two relay connectors 62 and 64 on the power supply side and the apparatus side, respectively.

  As shown in FIGS. 4 and 5, the independent connector 70, the first connector 66, and the second connector 68 each have step portions 70A, 66A, 68A on one long side at both ends in the longitudinal direction. It is formed in a rectangular shape. The longitudinal lengths of the independent connector 70, the first connector 66, and the second connector 68 are different from each other. For example, the first connector 66, the second connector 68, and the independent connector 70 are arranged in this order. It is formed so that the length becomes short.

  As shown in FIGS. 2 and 3, the connector holding member 50 has a metal main body 52 having an “L” shape in a side view. That is, the main body 52 has, for example, a bottom plate 52A fixed to the lower surface inside the apparatus main body 11, and a front plate 52B erected upward from one end in the depth direction of the bottom plate 52A. I have.

  The front plate 52B of the main body 52 has only a part of the two openings 56 and 58 that match the shape of the first connector 66 and the shape of the second connector 68 (at least differ in length in the longitudinal direction). Are formed, and an independent opening 60 (having a shape in which a plurality of openings are not overlapped) conforming to the shape of the independent connector 70 is formed.

  Specifically, when the longer one of the two openings 56 and 58 constituting the common opening 54 is the first opening 56 and the shorter one is the second opening 58, the first opening 56 The second opening 58 is formed such that the oblique direction with respect to the vertical and horizontal directions is the longitudinal direction.

  The independent opening 60 is formed so that the vertical direction is the longitudinal direction (so as to be parallel to the first opening 56). In addition, the independent opening 60, the first opening 56, and the second opening 58 are provided on one long side at both ends in the longitudinal direction, respectively, with steps 60A, 56A, 58A corresponding to the steps 70A, 66A, 68A. It is formed in a substantially rectangular shape having

  Therefore, the relay connector 62 (the first connector 66 or the second connector 68 and the independent connector 70) on the power supply side and the relay connector 64 (the first connector 66 or the second connector 68 and the independent connector 70) on the device side are respectively common. The insertion direction is fixed and inserted into the opening 54 and the independent opening 60 so that they are connected to each other.

  Thus, the relay connector 62 on the power supply side and the relay connector 64 on the device side are held by the connector holding member 50 in a state where their positions are determined. Note that only the first connector 66 corresponding to the first opening 56 or the second connector 68 corresponding to the second opening 58 is inserted into the common opening 54, and both the first connector 66 and the second connector 68 are inserted. Are not inserted at the same time (see FIGS. 4 and 5).

  That is, the common opening 54 has a prohibition function of prohibiting the insertion of the other one of the first connector 66 and the second connector 68 when one of the first connector 66 and the second connector 68 is inserted. It has a configuration to have.

  Further, as shown in FIG. 3, at least a part of each of the four edges of the first opening 56 and the second opening 58 is formed in the common opening 54. More specifically, the first opening 56 of the common opening 54 has a part of a long side 56B and a part of a long side 56C facing each other, and a part of a short side 56D and a part of a short side 56D facing each other. A part of the side portion 56E is formed.

  Similarly, the second opening 58 of the common opening 54 has a part of the long side 58B and a part of the long side 58C facing each other, and a part of the short side 58D and the short side facing each other. 58E are respectively formed.

  As shown in FIGS. 2 and 3, the first opening 56 and the second opening 58 do not overlap at an angle perpendicular to each other. In other words, the first opening 56 and the second opening 58 are configured to overlap at an acute angle (or an obtuse angle) θ (see FIG. 7A).

  Further, the first opening 56 and the second opening 58 are not overlapped so as to extend in the longitudinal direction. In other words, the first opening 56 and the second opening 58 intersect with each other at a middle part in the longitudinal direction. The second opening 58 is formed at a position that does not protrude above the first opening 56.

  In addition, the second opening 58 is such that the upper corner 58F and the lower corner 58G (see FIG. 3), which are one diagonal, are located on opposite sides of the first opening 56. Is formed. The first opening 56 and the second opening 58 are formed in a direction in which the step portions 56A and 58A are opposed to each other, but the present invention is not limited to this, and the step portions 56A and 58A are not limited to this. May be formed so as not to face each other.

  When viewed from a direction perpendicular to the thickness direction of the front plate 52 </ b> B constituting the main body 52, the independent opening 60 has a position where at least a part thereof, preferably the whole thereof, overlaps with the common opening 54. Is formed. That is, the independent opening 60 is formed, for example, on the obtuse angle side of the common opening 54 in the main body 52 (the front plate 52B) and below the second opening 58.

  More specifically, as shown in FIG. 3, the independent opening 60 has at least a central portion 60 </ b> C in the width direction (indicated by a phantom line) on the upper side where the step portion 58 </ b> A of the second opening 58 is not formed. The lower short side 60D does not protrude outward in the width direction than the corner 58F, and is formed at a position where the lower short side 60D does not protrude below the lower short side 56E of the first opening 56.

  That is, the whole of the independent opening 60 in the up-down direction overlaps with the common opening 54, and more than half (in part) in the width direction of the independent opening 60 overlaps with the common opening 54. In addition, the independent opening 60 shown in FIG. 3 is located at a position where the long side 60B outside the width direction in which the step portion 60A is formed does not protrude outward in the width direction from the corner 58F of the second opening 58. It may be formed, and that is more preferable.

  Next, the operation of the connector holding member 50 configured as described above will be described.

  As shown in FIG. 6, the image forming apparatus 10 is provided with a relay connector 62 on the power supply side and a relay connector 64 on the apparatus side. At least the length in the longitudinal direction is different. For example, in one image forming apparatus 10, an independent connector 70 and a first connector 66 are provided, and in another image forming apparatus 10, an independent connector 70 and a second connector 68 are provided.

  Therefore, conventionally, a connector holding member (not shown) having an opening in which the independent connector 70 can be inserted and an opening in which the first connector 66 can be inserted, and an opening in which the independent connector 70 can be inserted and the second connector 68 can be inserted. It is necessary to prepare two types of connector holding members, a connector holding member (not shown) having an opening having an opening.

  However, since the connector holding member 50 according to the present embodiment has the independent opening 60 into which the independent connector 70 can be inserted and the common opening 54 into which the first connector 66 or the second connector 68 can be inserted, Only one type is required. That is, the connector holding member 50 can be shared by the two types of image forming apparatuses 10. Therefore, the manufacturing cost of the connector holding member 50 is reduced as compared with the related art (compared to the case where two types of connector holding members must be manufactured), and as a result, the manufacturing cost of the image forming apparatus 10 is reduced.

  Further, as shown in FIG. 3, at least a part of each of the four edges of the first opening 56 and the second opening 58 is formed in the common opening 54. Therefore, the first connector 66 of the connector holding member 50 is different from the case where only three of the four edges of the first opening 56 and the second opening 58 are formed in the common opening 54. Alternatively, poor holding of the second connector 68 is suppressed or prevented. That is, even in the common opening 54 in which a part of the first opening 56 and a part of the second opening 58 are overlapped, the first connector 66 or the second connector 68 rattles on the connector holding member 50. Will be kept without.

  Also, as shown in FIG. 7A, the first opening 56 and the second opening 58 do not overlap at an angle orthogonal to each other. In other words, the first opening 56 and the second opening 58 are overlapped at an angle θ that forms an acute angle (or an obtuse angle) with each other. Therefore, as shown in FIG. 7B, the connector holding member 50 is compared with the connector holding member 150 according to the comparative example in which the first opening 156 and the second opening 158 are overlapped at an angle orthogonal to each other. The length of at least the width direction (the left-right direction) of the (main body 52) is reduced (reduced by the length L shown in FIG. 7A).

  Further, as shown in FIG. 7A, the first opening 56 and the second opening 58 are not overlapped so as to extend in the longitudinal direction. In other words, the first opening 56 and the second opening 58 intersect with each other at a middle part in the longitudinal direction. Therefore, as compared with the case where the first opening 56 and the second opening 58 are overlapped so as to extend in the longitudinal direction (they are overlapped at the ends in the longitudinal direction), the connector holding member 50 (the main body 52). ) Is reduced at least in the height direction (vertical direction).

  As shown in FIG. 3, at least a part of the independent opening 60 overlaps with the common opening 54 when viewed from a direction orthogonal to the thickness direction of the front plate 52 </ b> B in the main body 52. I have. Therefore, when viewed from a direction orthogonal to the thickness direction of the front plate 52 </ b> B in the main body 52, the connector holding member 50 (body The length of at least the width direction (left-right direction) and the height direction (vertical direction) of the portion 52) is reduced.

  It is preferable that the entirety of the independent opening 60 overlap the common opening 54 when viewed from a direction orthogonal to the thickness direction of the front plate 52 </ b> B in the main body 52. According to this, when viewed from a direction perpendicular to the thickness direction of the front plate 52 </ b> B in the main body 52, compared with the case where only a part of the independent opening 60 overlaps the common opening 54, the connector holding The length of at least the width direction (left-right direction) and the height direction (vertical direction) of the member 50 (the main body 52) is further reduced.

  In addition, there is an image forming apparatus 10 including a first connector 66 and a second connector 68 that cannot be used at the same time, as shown in FIG. 6, instead of one of the first connector 66 and the second connector 68. That is, there is also an image forming apparatus 10 in which three relay connectors 62 and 64 are provided on the power supply side and the apparatus side, respectively. In this case, the connector holding member 50 according to the present embodiment can be used particularly effectively.

  More specifically, when the independent connector 70, the first connector 66, and the second connector 68 on the power supply side are connected to the independent connector 70, the first connector 66, and the second connector 68 on the device side, the first connector 66 is used. In some cases, it is not necessary to connect both the first and second connectors 68 at the same time. For example, the first connectors 66 may be connected to each other, but the second connectors 68 may not be connected to each other.

  In this case, only one of the first connector 66 and the second connector 68 can be inserted into the common opening 54 of the connector holding member 50, so that both the first connector 66 and the second connector 68 can be connected simultaneously. Physically disabled. That is, when the first connectors 66 are connected to each other, it is physically impossible to connect the second connectors 68 to each other (as shown in FIG. 6, the second connector 68 is in a surplus state). .

  Therefore, an erroneous connection in which both the first connector 66 and the second connector 68 are simultaneously connected is automatically prevented. The fact that the first connector 66 and the second connector 68 cannot be used at the same time is generally described in a manual of the image forming apparatus 10 or the like. Thus, it can be said that the independent connector 70 is a connector that can be used simultaneously with the first connector 66 or the second connector 68.

  Further, in the present embodiment, the number of openings constituting the common opening 54 is two, that is, the first opening 56 and the second opening 58. However, the number of openings may be any number as long as it is plural. It is not limited. For example, as shown in FIG. 8, a part of the first opening 56, a part of the second opening 58, and a part of the third opening 57 may be formed as a common opening 54 that is overlapped with each other. Good. That is, three openings constituting the common opening 54 may be provided.

  The first opening 56, the second opening 58, and the third opening 57 are formed to have at least different lengths in the longitudinal direction. For example, the first opening 56, the second opening 58, and the third opening 57 are formed so that their lengths are reduced in this order. In FIG. 8, the independent opening 60 is omitted, but the length of the independent opening 60 is different from the length of the first opening 56, the second opening 58, and the third opening 57. I have.

  A step 57A is formed on one long side of both ends in the longitudinal direction of the third opening 57. In addition to the first opening 56 and the second opening 58 in the common opening 54, the third opening 57 also has a part of the long side 57B and a part of the long side 57C facing each other, and A part of the opposing short side 57D and a part of the short side 57E are respectively formed.

  In the present embodiment, one common opening 54 is formed in one main body 52, but the present invention is not limited to this. For example, when there are two connectors that can be used simultaneously other than the independent connector 70, as shown in FIG. 9, the configuration is such that two common openings 54 are formed in one main body 52 (front plate 52B). You may.

  That is, the image forming apparatus 10 is provided with a third connector (not shown) having at least a different longitudinal length from the independent connector 70, the first connector 66, and the second connector 68. When both the second connector and the third connector are connected, or when both the second connector 68 and the third connector are connected, the first common opening 54A and the second common opening are formed in one main body 52 (the front plate 52B). The configuration may be such that the portion 54B is formed. In this way, even if the number of connectors that can be used simultaneously increases, only one connector holding member 50 is required.

  Further, in this case, at least the length of the first opening 56 and the second opening 58 forming the first common opening 54A and the third opening 57 and the fourth opening 59 forming the second common opening 54B. Preferably, the lengths in the directions are all different lengths. For example, it is preferable that the first opening 56, the third opening 57, the second opening 58, and the fourth opening 59 are formed so that their lengths become shorter in this order. This prevents an erroneous connection in which unusable connectors are connected at the same time.

  More specifically, for example, when the length of the second opening 58 and the length of the third opening 57 are the same, the first connector 66 is inserted into the first opening 56 and the third opening 57 is inserted into the third opening 57. It becomes possible to insert the second connector 68, and at the same time, it becomes possible to connect the unusable first connector 66 and second connector 68. If the lengths of the first opening 56, the second opening 58, the third opening 57, and the fourth opening 59 are all different, such erroneous connection is prevented.

  Although the independent opening 60 is omitted in FIG. 9, the length of the independent opening 60 is also different from the first opening 56, the second opening 58, the third opening 57, and the fourth opening 59. Are of different lengths. A step 57A is formed on one long side at both ends in the longitudinal direction of the third opening 57, and a step is formed on one long side at both ends in the longitudinal direction of the fourth opening 59. A portion 59A is formed.

  Further, not only the first opening 56 and the second opening 58 in the first common opening 54A but also the third opening 57 in the second common opening 54B have a part and a length of the long side 57B opposed to each other. A part of the side 57C, a part of the short side 57D and a part of the short side 57E facing each other are formed. The fourth opening 59 in the second common opening 54B also has a part of the long side 59B and a part of the long side 59C facing each other, and a part of the short side 59D and the short side facing each other. And a part of the portion 59E.

  Although not shown, at least a part of the second common opening 54B overlaps the first common opening 54A when viewed from a direction orthogonal to the thickness direction of the front plate 52B constituting the main body 52. It may be formed at a wrapping position. Specifically, the second common opening 54B is formed, for example, at an obtuse angle side of the first common opening 54A and below the second opening 58 in the main body 52 (the front plate 52B), and in the vertical direction. May overlap with the first common opening 54A, and at least a part of its width may overlap with the first common opening 54A.

  As described above, the connector holding member 50 according to the present embodiment has been described with reference to the drawings. However, the connector holding member 50 according to the present embodiment is not limited to the illustrated one and does not depart from the gist of the present invention. The design can be appropriately changed within the range. For example, the main body 52 is not limited to metal (sheet metal) but may be made of resin.

  Further, the shape of the main body 52 is not limited to the illustrated shape, and may be, for example, a shape that is extended in the width direction (left-right direction) of the apparatus main body 11. Further, the shape of the common opening 54 is not limited to the illustrated shape. For example, the first opening 56 and the second opening 58 may be formed not only in the longitudinal direction but also in shapes having different lengths (widths) in a direction orthogonal to the longitudinal direction.
