Description

【０００１】
【発明の属する技術分野】
本発明は、第１のユニット装置に対して第２のユニット装置を開閉自在に結合するヒンジ装置に関するものであり、詳しくはこのヒンジ装置を取り付ける取付構造に関する。
【０００２】
【従来の技術】
従来、ヒンジ装置においては、本体等のユニットに取り付けられるベ−ス部材と蓋体やカバー等のユニットを取り付けるア−ム部材とを回動ピンで連結し、この回動ピンを支点としてベ−ス部材とア−ム部材が相対的に回動するように構成されている。
【０００３】
これによって、本体等のユニットに対して蓋体や力バー等のユニットが回動されて本体等のユニットの一面を開閉することができるようになっている。
【０００４】
このようなヒンジ装置の採用された装置としては、例えば、原稿読取装置等があり、この原稿読取装置は、原稿の画像を読み取るＣＣＤ等の読取センサが設けられた原稿読取装置本体と、原稿読取装置の上面を覆うカバ−部材や原稿を読取位置に搬送する搬送機構が設けられた原稿送り装置とが別ユニットとして形成されている。
【０００５】
そして、画像読取装置本体に対して原稿搬送装置がヒンジ装置によって取り付けられるように構成されている。
【０００６】
このような原稿読取装置では、予め原稿送り装置に取り付けられたヒンジ装置のベース部材を取付ネジで原稿読取装置本体に固定することにより原稿送り装置を原稿読取装置本体に取り付けている。
【０００７】
つまり、ベース部材の取付位置が原稿読取装置本体に対する原稿送り装置の位置基準となっている。
【０００８】
ここで、ヒンジ装置のベース部材をネジで原稿読取装置本体に固定するためのヒンジ装置のベース部材のネジ孔は原稿読取装置のネジ孔に対して大きく形成されており、これにより、部品の誤差等による位置ズレを調整し、原稿読取装置に対する原稿送り装置が適正な位置に取り付けられている。
【０００９】
つまり、従来の取り付け方法では、原稿読取装置に対する原稿送り装置の位置の調整範囲が取付ネジのネジ部の直径とベース部材のネジ孔の直径によって決まることとなり、ネジ部の直径に対してベース部材のネジ孔の直径をより大きくすることによって、調整範囲は大きくなり調整や取り付けが容易となる。
【００１０】
また、上述したベース部材の取付位置が原稿読取装置本体に対する原稿送りを装置の位置基準となっているようなものでなく、例えば原稿読取装置本体に基準ピンを２本立て、この基準に対応して、原稿送り装置に孔を設け、この基準ピンを原稿送り装置の孔に嵌合させて読取装置本体に対する原稿搬送装置の位置が決められて、その後にヒンジ装置のベース部材を固定して原稿読取装置本体に原稿送り装置を取り付けるような、基準ピンとこの基準ピンに嵌合する原稿送り装置の孔を基準として、原稿読取装置本体に対する原稿送り装置の取り付けられるものもある。
【００１１】
【発明が解決しようとする課題】
しかし、実際には取付ネジのネジ頭部の直径は標準品の場合、取付ネジのネジ部の直径によって定められており、このネジ頭部の直径よりもベース部材のネジ孔は小さくなければならない。このため、調整範囲は狭くなり、その調整、及び取り付けに困難が生じるとの間題があった。
【００１２】
本願発明は、上記問題点に鑑みてなされたものであって、一方のユニットに対してのユニットの取り付け、及び位置調整が容易にできる装置を提供することを目的とする。
【００１３】
【発明の実施の形態】
図１、２は本発明のヒンジ装置にて適応される原稿読取装置を示しており、図１は原稿読取装置本体に原稿送り装置が取り付けられた状態を示す図であり、図２は原稿読取装置本体、及び原稿送り装置の断面図である。
【００１４】
図１に示すように原稿読取装置１の上面には原稿送り装置２がヒンジ３によって回動自在に取り付けられている。
【００１５】
また、原稿読取装置１は、光源１１、複数の反射ミラ−１２、レンズ１３、ＣＣＤ１４、及び制御基板１５からなる読取手段が設けられており、この読取手段によって厚紙やブック物を載置する第１のコンタクトガラス１０ａ上に載置された原稿や原稿送り手段にて搬送される原稿を読み取るための第２のコンタクトガラス１０ｂに搬送された原稿が読み取られるように構成されている。
【００１６】
原稿送り装置２は、原稿を載置する原稿トレイ２０、原稿を第２のコンタクトガラス１０ｂ上に給紙し、第２のコンタクトガラス１０ｂにて読み取られた原稿を排紙する原稿搬送機構２１、読み取られた原稿を収納する排紙トレイ２２、及び第１のコンタクトガラス１０ａを覆うカバー部材２３を備えている。
【００１７】
ヒンジ装置３は図３に示すように、原稿読取装置本体１の上面に取り付けられるベース部材３０と、原稿送り装置２を取り付けるアーム部材３１を備え、ベース部材３０及びアーム部材３１は略コ字形状に形成されている。
【００１８】
コの字形状に形成されたベ−ス部材３０の両側面部３０ａと同じくコの字形状に形成されたア−ム部材３１の両側面部３１ａとは軸ピン３２によって連結されており、この軸ピン３２を支点として、ア−ム部材３１がベ−ス部材３０に対して回動するように構成されている。
【００１９】
また、ベ−ス部材３０の両側面３０ａに軸着された第１の受部材３３ｂとア−ム部材３１の両側面３１ａに軸支された第２の受部材３３ａの間にはベ−ス部材３０に対してア−ム部材３１が開く方向に付勢するスプリング３３が設けられている。
【００２０】
このスプリング３３は、開閉角度が所定の角度以上においてはベース部材３０に対してアーム部材３１が開く方向、つまり原稿読取装置本体１に対して原稿送り装置２が開くように作用するが、所定以下の角度ではアーム部材３１に取り付けられた原稿送り装置の自重によるアーム部材３１の閉まり方向への力がスプリング３３の開き方向の力よりも大きくなり原稿送り装置２が原稿読取装置本体１に対して閉じることとなる。
【００２１】
ベース部材３０の底面部３０ｂの上には剛性の板部材３４が設けられている。この板部材３４は、原稿読取装置本体１の上面との間にベース部材３０の底面部３０ｂを挟んで保持する。つまり、取付ネジ３５、段付ネジ３６によって板部材３４を原稿読取装置本体１側に圧接してベース部材３０を原稿読み取り装置本体１上面の所定の位置に保持するように構成されている。
【００２２】
ベース部材３０の底面部３０ｂには、取付ネジ３５、段付ネジ３６が貫通させる貫通孔３０ｃが形成されており、この貫通孔３０ｃは原稿読取装置本体１の上面と板部材３４に挟まれたベース部材が移動可能なように取付ネジ３５、及び段付ネジ３６のネジ部の直径に対して大きく形成されている。これによって、原稿読取装置本体１に対してヒンジ装置３を移動して、原稿読取装置本体１と原稿送り装置２との位置決めをするようになっており、ここでは、ヒンジ装置３の取り付けが確実になされるようにベース部材３０の貫通孔３０ｃを少なくとも取付ネジ３５のネジ頭の直径よりも大きく形成している。
【００２３】
次に原稿送り装置２の原稿読み取り装置本体への取り付け方法、及び調整方法を述べる。
【００２４】
まず、原稿送り装置２に取り付けられたヒンジ装置３のベ−ス部材３０の低面部３０ｂの上に板部材３４を配置し、取付ネジ３５及び段付ネジ３６によって板部材３４と原稿読取装置本体１とを連結することにより原稿送り装置２の原稿読取装置本体１に対するある程度の位置が決められる。このとき、取付ネジ３５と段付ネジ３６は緩めており、ベ−ス部材３０は、貫通孔３３０ｃの範囲で移動が可能な状態にある。
【００２５】
次に、原稿読取装置本体１の上面に設けられた２本の基準ピン１６に原稿送り装置２の嵌合孔２４を嵌合するように原稿送り装置２を移動させながら、原稿読取装置本体１上に閉じ、原稿読取装置本体１に対して原稿送り装置２の位置を決める。
【００２６】
そして、再び原稿送り装置２を開状態として取付ネジ３５を締める。これによって、ヒンジ装置３のベース部材３０の底面部３０ｃを板部材３４が原稿読取装置本体１の上面との間で挟んで保持されて固定される。
【００２７】
以下に上述したヒンジ装置に係る変形例を以下に説明する。
【００２８】
変形例１では、図５に示すようにベース部材３０の底面部３０ｃをアーム部材３１の開方向に延設した延設部４２を形成し、この延設部４２上に第２の板部材４０を設け、この板部材４０と原稿読取装置本体１の上面との間にベース部材３０の延設部４２を取付ネジ４１によって挟んで保持するようになる。なお、ベース部材３０の延設部４２に形成された取付ネジ４１の貫通孔４３は、ベース部材３０の底面部４０ｃに形成された貫通孔３０ｃと同様にヒンジ装置３が板部材４１と原稿読取装置本体１上面との間で移動可能なように取付ヒンジ４１の頭部の直径よりも大きく形成されている。
【００２９】
これによって、取付ネジ４１はヒンジ装置３、すなわち原稿送り装置２の開閉状態に係らず締め付けることが可能となり、原稿読取装置本体１に対して原稿送り装置２の位置を決めた後に取付ネジ４１を締め付け、それから原稿送り装置２を開状態として取付ネジ３５を締めつけることで、原稿送り装置２の開状態にする際に位置決めされたヒンジ装置３がずれることがない。
【００３０】
なお、板部材３４と第２の板部材４０とを別々に設けたが、板部材３４と第２の板部材４０を一体の板部材で形成してもよい。
【００３１】
変形例２では、図６に示すように板部材５０をＬ字状に形成し、このＬ字状の板部材５０の折曲部５０ａとベース部材３０の背面部３０ｄとの間にベース部材３０を微小に移動させる調整手段としての調整ネジを設ける構成とする。
【００３２】
調整ネジ５１は図８で示すような板状部材５０の板厚に対応した間隔で設けられたフランジ５１ａが設けられており、このフランジ５１ａ間の凹部を板部材５０の折曲部５０ａに設けた切欠５１ｂに嵌め込むことにより板部材５０と連結している。これによって、調整ネジ５１は回転自在に板部材５０に保持され、調整ネジ５０をドライバ−等の工具で回転させるとベ−ス部材３０が移動する。
【００３３】
このように、ヒンジ装置３のベ−ス部材３０の位置を微小に調整する調整手段を設けることにより、原稿読み取り装置本体１に原稿送り装置２を取り付けた後に、実際に原稿を原稿搬送機構２１で原稿を第２のコンタクトガラス１０ｂに搬送して読取手段で読み取り、この読み取った画像が原稿に対して傾いて読み取られている場合に、原稿送り装置２を微小に調整できるので、良好な画像が確実に得ることができる。
【００３４】
なお、変形例２では、ベース部材のアーム部材３１の閉万向の一部に設けた板部材５０とベース部材３０との間に調整ネジ５１を設けたが、変形例１のような構成では図８に示すようにベース部材３０の底面部３０ｃを延設した延設部４２に配置された板部材６０をＬ字状に折り曲げ、この折り曲げられた板部材６０の折曲部６０ａとベース部材の背面部３０ｄとの間に調整ネジを設けてもよい。
【００３５】
上記実施の形態によれば、原稿読取装置本体上に位置決めされるヒンジ装置のベース部材を板状の保持部材にて挟み付けて決められた値置に保持する構成とで、ヒンジ装置のベース部材の移動できる範囲が大きくなり、原稿読取装置本体に原稿送り装置を取り付けることが容易になる。

BACKGROUND OF THE INVENTION
The present invention relates to a hinge device that couples a second unit device to a first unit device so as to be openable and closable. Specifically, the present invention relates to a mounting structure for attaching the hinge device.
[0002]
[Prior art]
Conventionally, in a hinge device, a base member attached to a unit such as a main body and an arm member to which a unit such as a lid or a cover is attached are connected by a rotation pin, and the rotation pin serves as a fulcrum. The sleeve member and the arm member are configured to rotate relatively.
[0003]
As a result, a unit such as a lid or a force bar is rotated with respect to the unit such as the main body so that one surface of the unit such as the main body can be opened and closed.
[0004]
As an apparatus employing such a hinge device, for example, there is a document reading device or the like. This document reading device includes a document reading device main body provided with a reading sensor such as a CCD for reading a document image, and a document reading device. A cover member that covers the upper surface of the apparatus and a document feeder provided with a transport mechanism for transporting a document to a reading position are formed as separate units.
[0005]
The document conveying apparatus is attached to the image reading apparatus main body by a hinge device.
[0006]
In such a document reading apparatus, the document feeding apparatus is attached to the document reading apparatus main body by fixing the base member of the hinge device previously attached to the document feeding apparatus to the document reading apparatus main body with an attaching screw.
[0007]
That is, the attachment position of the base member is the position reference of the document feeder with respect to the document reader main body.
[0008]
Here, the screw hole of the base member of the hinge device for fixing the base member of the hinge device to the main body of the document reading device with a screw is formed to be larger than the screw hole of the document reading device. The document feeding device with respect to the document reading device is attached at an appropriate position by adjusting the positional deviation due to the above.
[0009]
That is, in the conventional attachment method, the adjustment range of the position of the document feeder relative to the document reading device is determined by the diameter of the screw portion of the attachment screw and the diameter of the screw hole of the base member. By making the diameter of the screw hole larger, the adjustment range becomes larger and adjustment and attachment become easier.
[0010]
Further, the attachment position of the base member described above is not such that the document feeding with respect to the document reading apparatus main body is the position reference of the apparatus. For example, two reference pins are set up on the document reading apparatus main body, and this reference is supported. The document feeder is provided with a hole, the reference pin is fitted into the hole of the document feeder, the position of the document feeder relative to the reader body is determined, and then the base member of the hinge device is fixed to read the document. In some cases, the document feeder is attached to the document reader main body with reference to a reference pin and a hole of the document feeder fitted to the reference pin, such as a document feeder attached to the apparatus body.
[0011]
[Problems to be solved by the invention]
However, in reality, the diameter of the screw head of the mounting screw is determined by the diameter of the screw portion of the mounting screw in the case of a standard product, and the screw hole of the base member must be smaller than the diameter of this screw head. . For this reason, the adjustment range becomes narrow, and there is a problem that adjustment and attachment are difficult.
[0012]
This invention is made | formed in view of the said problem, Comprising: It aims at providing the apparatus which can attach the unit with respect to one unit, and can adjust position easily.
[0013]
