本発明によれば、画像形成装置の操作部のハーネスを効率良くはいまわすことができる。 According to the present invention, the harness of the operation unit of the image forming apparatus can be efficiently handled.
本発明は、画像形成装置の操作部保持機構、具体的な例で言えば画像形成装置の操作部チルト機構における、ハーネスの這い回しに際して、操作部の回動中心上にハーネスをはいまわすようにして、操作部を回動させた際にもハーネス経路長を変化させることなくハーネスをはいまわすことができるようにするものである。 According to the present invention, the harness is wound around the rotation center of the operation unit when the harness is wound in the operation unit holding mechanism of the image forming apparatus, specifically, the operation unit tilt mechanism of the image forming apparatus. Thus, the harness can be operated without changing the harness path length even when the operation unit is rotated.
以下、本発明の実施例について説明する。
図１は、画像形成装置１（どのようなものでも本発明を適用できるので、具体的な図示は省略する）に回動可能に設ける操作部２の二軸チルトのヒンジ機構について説明する斜視図である。
Examples of the present invention will be described below.
FIG. 1 is a perspective view for explaining a biaxial tilt hinge mechanism of an operation unit 2 that is rotatably provided in an image forming apparatus 1 (anything is applicable to the present invention, and a specific illustration is omitted). It is.
図中３は画像形成装置本体４側に設けた板状の保持部材で、操作部２を設ける側に向く先端側に、操作部２を回動可能に保持するための切り欠き開口５を備えている。切り欠き開口５には図１（Ａ）で示すように外ネジ付きの貫通軸６を設けてある。 In the figure, reference numeral 3 denotes a plate-like holding member provided on the image forming apparatus main body 4 side, and a notch opening 5 for rotatably holding the operation unit 2 is provided on the tip side facing the side where the operation unit 2 is provided. ing. The notch opening 5 is provided with a through shaft 6 with an external thread as shown in FIG.
また操作部２と保持部材３の間に介在する中間ヒンジ７は、保持部材３に対して取り付けるためのベロ状の突片部７ａを備え、該部分に切り欠き開口８を形成してある。
さらに中間ヒンジ７は、チャンネル状に曲折した部分７ｂを有し、両端のフランジ部７ｃには、操作部７に設けた一対のヒンジへ回転可能に取り付けるための中空軸部９ａ、９ｂが同一の向き（図示の例では左側に）向けて設けてある。中空軸部９ａはフランジ部７ｃの外側に突出し、図中右側の中空軸部９ｂはフランジ部７ｃの内側に突出している。
Further, the intermediate hinge 7 interposed between the operation portion 2 and the holding member 3 is provided with a tongue-like projecting piece portion 7a to be attached to the holding member 3, and a notch opening 8 is formed in this portion.
Further, the intermediate hinge 7 has a portion 7b bent in a channel shape, and the hollow shaft portions 9a and 9b for rotatably attaching to the pair of hinges provided on the operation portion 7 are the same on the flange portions 7c at both ends. It is provided facing (to the left in the example shown). The hollow shaft portion 9a protrudes outside the flange portion 7c, and the right hollow shaft portion 9b protrudes inside the flange portion 7c in the drawing.
また操作部２には、中間ヒンジ７を受け入れるためのヒンジ１０、１０がそれぞれ中空穴１０ａを備えて一対形成してあり、中空穴１０ａに中間ヒンジ７の中空軸部９ａ、９ｂを受け入れて貫通させるようにしてある。 Further, the operation unit 2 is formed with a pair of hinges 10 and 10 for receiving the intermediate hinge 7 with hollow holes 10a, and the hollow shafts 9a and 9b of the intermediate hinge 7 are received through the hollow hole 10a. I am trying to make it.
なお図中１２はボルト、１３はワッシャで、中間ヒンジ７の中空軸部９ａや、保持部材３の外ネジ付きの貫通軸６を固定するように設けてある。 In the figure, 12 is a bolt and 13 is a washer, which is provided so as to fix the hollow shaft portion 9 a of the intermediate hinge 7 and the through shaft 6 with the external thread of the holding member 3.
この装置における操作部２のチルト機構としては、装置本体４側に設けられ、回動中心となる軸により中間ヒンジ７が回動可能に保持され、操作部２に設けられたヒンジ１０、１０と中間ヒンジ７の中空軸部９ａ、９ｂの嵌合により中間ヒンジ７も回動可能に保持され、全体として画像形成装置１に対して操作部２は上下方向、左右方向に自由に回動できるようになっており、さらに回動中心となる軸が中空になっていて、操作部２の信号伝達用のハーネス２０を通すことができるようになっている。そして、構造が一定になることで、操作部２のハーネス２０を前記のように通すとハーネス２０の経路長を一定にすることが可能になっている。 The tilt mechanism of the operation unit 2 in this apparatus is provided on the apparatus body 4 side, the intermediate hinge 7 is rotatably held by an axis serving as a rotation center, and the hinges 10 and 10 provided in the operation unit 2 The intermediate hinge 7 is also rotatably held by fitting the hollow shaft portions 9a and 9b of the intermediate hinge 7, so that the operation unit 2 can freely rotate in the vertical and horizontal directions with respect to the image forming apparatus 1 as a whole. Furthermore, the shaft serving as the center of rotation is hollow, so that the signal transmission harness 20 of the operation unit 2 can be passed therethrough. And since the structure becomes constant, when the harness 20 of the operation unit 2 is passed as described above, the path length of the harness 20 can be made constant.
図１（Ｂ）は、ヒンジ部の切りかき形状について説明する図である。図１（Ｂ）は図１（Ａ）の画像形成装置本体４側と保持部材３の中間ヒンジ部の嵌合部を拡大して示している。 FIG. 1B is a diagram for explaining the notch shape of the hinge portion. FIG. 1B shows an enlarged view of the fitting portion between the image forming apparatus main body 4 side and the intermediate hinge portion of the holding member 3 in FIG.
保持部材３の切り欠き開口５の切り欠き５ａと、中間ヒンジ７の突片部７ａに設けた切り欠き開口８とは、切り欠き５ａ、８ａ同士の位置が通常の中間ヒンジ７の回動領域では一致することのないように配置してある。 The notch 5a of the notch opening 5 of the holding member 3 and the notch opening 8 provided in the projecting piece 7a of the intermediate hinge 7 are such that the positions of the notches 5a and 8a are normal rotation regions of the intermediate hinge 7. Then, they are arranged so that they do not match.
図示の例では、組み合わせる際は、切り欠き５ａ、８ａがそれぞれの切り欠き開口５、８の径方向で反対側に位置するように形成してある。切り欠き開口５の切り欠き５ａには、中間ヒンジ７を回動可能に保持するために切り欠き開口８の縁を引っ掛けける突起５ｂ、５ｂが一対設けててあり、いったん取り付けた中間ヒンジ７の突片部７ａが容易に外れないようにしてある。なお図１（Ｂ）は、外ネジ付きの貫通軸６の図示は省略してある。またなお、装置本体４側の切りかきと、中間ヒンジの切り欠きは通常回動領域では一致することのない様に配置するとハーネス２０がはさまったりし難く、装置本体４側での引っ掛けと、中間ヒンジ７側の切り欠き５は操作部２を装置本体４に組付けた状態においての通常の回動領域外に設けると円滑に回動しやすい。 In the illustrated example, when combining, the notches 5a and 8a are formed so as to be located on the opposite sides in the radial direction of the notch openings 5 and 8, respectively. The notch 5a of the notch opening 5 is provided with a pair of protrusions 5b and 5b for hooking the edge of the notch opening 8 in order to hold the intermediate hinge 7 in a rotatable manner. The protruding piece 7a is not easily detached. In FIG. 1B, illustration of the through shaft 6 with an external screw is omitted. In addition, if the notch on the apparatus main body 4 side and the notch of the intermediate hinge are arranged so as not to coincide with each other in the normal rotation region, the harness 20 is difficult to be caught. If the notch 5 on the intermediate hinge 7 side is provided outside the normal rotation region in a state in which the operation unit 2 is assembled to the apparatus main body 4, it is easy to rotate smoothly.
このような状態で、図１（Ａ）に示すように、操作部２から導出された信号伝達用のハーネス２０を、
・操作部２のヒンジ１０の中空穴１０ａに取り付ける操作部２のボルト１２の穴、ワッシャ１３の穴、ヒンジ１０の中空穴１０ａを通し、
・ついで中間ヒンジ７の中空軸部９ａの穴、ボルト１２の穴、ワッシャ１３の穴、中間ヒンジ７の突片部７ａの切り欠き開口８を通し、
・最後に、保持部材３の切り欠き開口５を通してコネクタ２１に接続する。
In such a state, as shown in FIG. 1A, the signal transmission harness 20 derived from the operation unit 2 is
-Through the hole of the bolt 12 of the operation unit 2 to be attached to the hollow hole 10a of the hinge 10 of the operation unit 2, the hole of the washer 13, and the hollow hole 10a of the hinge 10,
Next, through the hole of the hollow shaft portion 9a of the intermediate hinge 7, the hole of the bolt 12, the hole of the washer 13, and the notch opening 8 of the protruding piece portion 7a of the intermediate hinge 7,
-Finally, it connects to the connector 21 through the notch opening 5 of the holding member 3.
なお、各部のネジによる嵌合などはハーネス２０を通した後のほうがやりやすいことはもちろんであるが、本発明の実施に当たってはこれに限定されず、途中まで組み立てた状態で通したり、完全に組み立てた後に通したりすることもできなくはない。 It should be noted that fitting with screws of each part is easier to do after passing through the harness 20, but is not limited to this in the practice of the present invention, and it can be passed in an assembled state completely or completely. It can not be passed through after assembly.
