電装部６０の周辺の構成について詳述する。図２は、電装部６０を開いた場合の電装部付近を示す斜視図である。図３は、電装部６０を閉じた場合の電装部付近を示す斜視図である。   The configuration around the electrical unit 60 will be described in detail. FIG. 2 is a perspective view showing the vicinity of the electrical component when the electrical component 60 is opened. FIG. 3 is a perspective view showing the vicinity of the electrical component when the electrical component 60 is closed.

前述した画像形成装置本体１６には本体側フレーム６２が設けられている。一方、電装部６０は、配線基板６４と、この配線基板６４を保持する配線基板保持部６６とを有する。本体側フレーム６２と配線基板保持部６４とは支持部６８，６８を介して回転自在に連結され、これにより画像形成装置本体１６に対して電装部６０が回転自在となっている。この電装部６０の開閉は、画像形成装置のメンテナンスをする場合などに行われる。   The image forming apparatus main body 16 described above is provided with a main body side frame 62. On the other hand, the electrical unit 60 includes a wiring board 64 and a wiring board holding part 66 that holds the wiring board 64. The main body side frame 62 and the wiring board holding part 64 are rotatably connected via support parts 68, 68, whereby the electrical unit 60 is rotatable with respect to the image forming apparatus main body 16. The electrical component 60 is opened and closed when maintenance of the image forming apparatus is performed.

支持部６８，６８は、例えば、鉛直方向に２つ設けられたヒンジから構成されている。即ち、例えば本体側フレーム６２にヒンジ受け７０，７０が設けられ、基板保持部６６に挿入部７２，７２が設けられ、挿入部７２，７２がヒンジ受け７０，７０に回転自在であるように挿入されて構成されている。この支持部６８，６８の回転中心となる軸線がＬとして図２に表示されている。   The support parts 68 and 68 are comprised from the hinge provided in the perpendicular direction, for example. That is, for example, the body side frame 62 is provided with hinge receivers 70, 70, the board holding part 66 is provided with insertion parts 72, 72, and the insertion parts 72, 72 are inserted into the hinge receivers 70, 70 so as to be rotatable. Has been configured. An axis that becomes the rotation center of the support portions 68 and 68 is indicated as L in FIG.

複数の配線７４ａ，７４ｂ，７４ｃ，７４ｄ（任意の配線を表示する場合は配線７４とする。）は、本体側と電装部６０の配線基板６４とを電気的に接続する。例えば配線７４ａはユーザインターフェイス用で、前述した表示操作装置５８と配線基板６４とを接続する。例えば配線７４ｂは読取画像の伝送用で、前述した原稿読取装置１４と配線基板６４とを接続する。例えば配線７４ｃはＵＳＢ用で、図示しないＵＳＢ接続部と配線基板６４とを接続する。例えば配線７４ｄは画像読取装置制御信号伝送用で、原稿読取装置１４と配線基板６４とを接続する。   A plurality of wirings 74a, 74b, 74c, and 74d (in the case of displaying arbitrary wiring, the wiring 74 is used) electrically connects the main body side and the wiring board 64 of the electrical component 60. For example, the wiring 74 a is used for a user interface, and connects the display operation device 58 and the wiring board 64 described above. For example, the wiring 74b is for transmitting a read image, and connects the document reading device 14 and the wiring board 64 described above. For example, the wiring 74c is for USB, and a USB connection unit (not shown) and the wiring board 64 are connected. For example, the wiring 74d is for transmitting an image reading device control signal, and connects the document reading device 14 and the wiring board 64.

配線集合部材７６は、複数の配線７４を束ねて保持する。この配線集合部材７６は、配線基板保持部６６に固定され、電装部７０が開閉される場合は電装部７０と共に回転する。この配線集合部材７６は、上方に位置する支持部６８よりも上部に設けられている。さらにこの配線集合部材７６は、前述した支持部６８，６８の軸線Ｌ上に配置されている。ここで、軸線Ｌ上に配置されているとは、軸線Ｌが少なくとも配線集合部材７６の一部に当たることを意味する。電装部６０が開閉された場合、配線７４は、配線集合部材７６に保持された部分を中心として回転し、曲げられると共に軸方向に移動するが、配線集合部材７６が支持部６８，６８の軸線Ｌ上に配置されているので、配線７４の移動量が少なくなっている。   The wiring assembly member 76 holds a plurality of wirings 74 in a bundle. The wiring assembly member 76 is fixed to the wiring board holding unit 66 and rotates together with the electrical component 70 when the electrical component 70 is opened and closed. The wiring assembly member 76 is provided above the support portion 68 positioned above. Further, the wiring assembly member 76 is disposed on the axis L of the support portions 68 and 68 described above. Here, being disposed on the axis L means that the axis L hits at least a part of the wiring assembly member 76. When the electrical component 60 is opened and closed, the wiring 74 rotates around the portion held by the wiring assembly member 76, is bent, and moves in the axial direction. However, the wiring assembly member 76 is the axis of the support portions 68 and 68. Since it is arranged on L, the movement amount of the wiring 74 is reduced.

分岐部７８は、配線基板保持部６６にあって、配線集合部材７６と配線基板６４との間に設けられている。この分岐部７８は、配線集合部材７６により束ねられた各配線７４を分岐し、分岐された配線７４が配線基板６４に接続しやすくしてある。   The branch part 78 is provided in the wiring board holding part 66 and is provided between the wiring assembly member 76 and the wiring board 64. This branching portion 78 branches each wiring 74 bundled by the wiring assembly member 76 so that the branched wiring 74 can be easily connected to the wiring board 64.

配線７４は太さが異なる。即ち、この実施形態においては、ユーザインターフェイス用の配線７４ａが他の配線７４ｂ〜７４ｄと比較して最も太いが、この配線７４ａは、本体側では他の配線７４ｂ〜７４ｄよりも上方に位置し、分岐部７８では他の配線７４ｂ〜７４ｄよりも下方に位置する。このため、電装部６０が開閉された場合、配線７４ａの曲げ度合いが他の配線７４ｂ〜７４ｄよりも小さく、配線７４ａに対する負荷が少なくなるようにしてある。   The wiring 74 has a different thickness. That is, in this embodiment, the user interface wiring 74a is the thickest compared to the other wirings 74b to 74d, but the wiring 74a is positioned above the other wirings 74b to 74d on the main body side, The branch portion 78 is positioned below the other wirings 74b to 74d. For this reason, when the electrical component 60 is opened and closed, the degree of bending of the wiring 74a is smaller than that of the other wirings 74b to 74d, and the load on the wiring 74a is reduced.

なお、図３に示すように、電装部６０が閉じられている場合は、電装部６０の周囲はカバー（被覆部）８０に覆われている。このカバー８０は、本体側フレーム６２に着脱自在にはめ込まれる。   As shown in FIG. 3, when the electrical component 60 is closed, the periphery of the electrical component 60 is covered with a cover (covering portion) 80. The cover 80 is detachably fitted to the main body side frame 62.

次に配線集合部材７６について詳述する。
図４は、配線集合部材７６の平面図であり、図５は、図４のＡ方向から見た側面図であり、図６は、図５のＢ−Ｂ線断面図である。 Next, the wiring assembly member 76 will be described in detail.
4 is a plan view of the wiring assembly member 76, FIG. 5 is a side view seen from the direction A in FIG. 4, and FIG. 6 is a cross-sectional view taken along the line BB in FIG.

配線集合部材７６は、上下に対向する案内部８２，８２を有する。この案内部８２，８２の間の空間に配線７４が挿入され、配線７４の上下方向の移動を規制するようになっている。また、配線集合部材７６は、カバー側側面８４、本体側側面８６及び基板回路側側面８８を有する。カバー側側面８４は、案内部８２，８２間を閉鎖接続する接続壁９０を有する。このカバー側側面８４は、内側に凹むように曲面状に形成されており、図３に示すように、カバー８０の角部分が当たるのを防止するようにしてある。また、このカバー側側面８４の接続壁９０により案内部８２，８２間に挿入された配線７４のカバー側への移動が規制される。   The wiring assembly member 76 includes guide portions 82 and 82 that face each other vertically. A wiring 74 is inserted into the space between the guide portions 82 and 82 so as to restrict the vertical movement of the wiring 74. Further, the wiring assembly member 76 has a cover side surface 84, a main body side surface 86, and a substrate circuit side surface 88. The cover side surface 84 has a connection wall 90 that connects the guide portions 82 and 82 in a closed manner. The cover side surface 84 is formed in a curved shape so as to be recessed inward, and prevents the corner portion of the cover 80 from hitting as shown in FIG. Further, the movement of the wiring 74 inserted between the guide portions 82 and 82 toward the cover side is restricted by the connection wall 90 on the cover side surface 84.

本体側側面８６は本体側に向けて開放され、配線７４の入口となっている。この本体側側面８６は、外側へ突出するように曲面状に形成されており、図３に示すように、電装部６０の開閉に伴って本体側フレーム６２に当たるのを避けるようにしてある。基板回路側側面８８は分岐部７８に向けて開放され、配線７４の出口となっている。   The main body side surface 86 is opened toward the main body side and serves as an entrance of the wiring 74. The main body side surface 86 is formed in a curved shape so as to protrude outward, and as shown in FIG. 3, it avoids hitting the main body side frame 62 when the electrical component 60 is opened and closed. The substrate circuit side surface 88 is opened toward the branch portion 78 and serves as an outlet of the wiring 74.
