Description

本発明は、複写機、印刷機、ファクシミリ、スキャナー等の事務機器に用いて好適な原稿圧着板開閉保持装置及びこれを備えた事務機器に関するものである。   The present invention relates to a manuscript crimping plate opening / closing device suitable for use in office equipment such as a copying machine, a printing machine, a facsimile machine, and a scanner, and office equipment provided with the same.

複写機、印刷機、ファクシミリ、スキャナー等の事務機器の装置本体には、その装置本体の上面に対して原稿圧着板が開閉装置を介して回動可能に取り付けられている。この原稿圧着板の開閉装置は、当該原稿圧着板の後部を回動可能に支持して、装置本体の上面のコンタクトガラス上を原稿圧着板で覆うことができると共に、原稿圧着板の前部を持ち上げることにより、そのコンタクトガラスを露出させることができるようになっている。原稿圧着板は、事務機器を使用しないときには、通常、装置本体の上面のコンタクトガラス上に密着して閉じられている。   A document crimping plate is attached to an apparatus main body of an office machine such as a copying machine, a printing machine, a facsimile machine, and a scanner via an opening / closing device so as to be rotatable with respect to the upper surface of the apparatus main body. The document crimping plate opening / closing device can pivotally support the rear portion of the document crimping plate so as to cover the contact glass on the upper surface of the apparatus main body with the document crimping plate, and to cover the front portion of the document crimping plate. The contact glass can be exposed by lifting. When the office equipment is not used, the document crimping plate is normally closed in close contact with the contact glass on the upper surface of the apparatus main body.

近年の、複写機などの事務機器などにおいては、原稿圧着板には自動原稿送り装置（ＡＤＦ）が備えられた重量のあるものが多く用いられている。その場合、自動原稿送り装置を用いないで原稿をコンタクトガラス上にセットするには、原稿圧着板を開いてコンタクトガラスを露出（開放）させる必要があり、露出させたコンタクトガラスの面上に原稿を載置した後、原稿圧着板を閉じて、当該原稿圧着板で原稿をコンタクトガラス上に圧着させるものである。   2. Description of the Related Art In recent office equipment such as a copying machine, a heavy document crimping plate equipped with an automatic document feeder (ADF) is often used. In that case, in order to set the document on the contact glass without using the automatic document feeder, it is necessary to open (open) the contact glass by opening the document pressing plate, and the document is placed on the exposed surface of the contact glass. Then, the original cover is closed and the original is pressed onto the contact glass with the original cover.

これらの原稿圧着板は、従来、例えば下記特許文献１に示されているように、その後部を装置本体に対して一対の原稿圧着板開閉装置により回動可能に取り付けると共に、当該原稿圧着板開閉装置に内蔵された強力なコイルスプリングから成る弾性手段によって原稿圧着板を開成方向へ付勢するようになっており、開いた原稿圧着板は、スプリングの弾力によって開成状態で保持される構成となっている。したがって、装置本体の修理時やメンテナンス時において原稿圧着板を開成状態で保持できることから、修理作業やメンテナンス作業が行い易くなっている。   Conventionally, as shown in Patent Document 1 below, for example, these document crimping plates are rotatably attached to the apparatus main body by a pair of document crimping plate opening / closing devices, and the document crimping plate opening / closing is also performed. The document pressing plate is urged in the opening direction by elastic means comprising a powerful coil spring built in the apparatus, and the opened document pressing plate is held in the open state by the elasticity of the spring. ing. Accordingly, since the original pressing plate can be held in an open state during repair or maintenance of the apparatus main body, repair work and maintenance work are facilitated.

然しながら、安価な事務機器においては、下記特許文献１に示したような構成の原稿圧着板開閉装置ではなく、もっと簡単な構成の原稿圧着板開閉装置が用いられており、かかる構成簡単で安価な原稿圧着板開閉装置は、原稿圧着板を全開させた状態での修理作業やメンテナンス作業時に、当該原稿圧着板を開成状態で保持させることができないことから、装置本体の修理作業やメンテナンス作業がしにくいといった問題があった。   However, in inexpensive office equipment, a document crimping plate opening / closing device having a simpler configuration is used instead of the document crimping plate opening / closing device having the configuration shown in Patent Document 1 below, and such a configuration is simple and inexpensive. The document crimping plate opening / closing device does not allow the document crimping plate to be held open when it is repaired or maintained with the document crimping plate fully open. There was a problem that it was difficult.

以下、本発明に係る原稿圧着板開閉保持装置の一実施例、及びこれを備えた事務機器を添付図面に基づいて説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a document crimping plate opening and closing device according to the present invention and office equipment provided with the same will be described below with reference to the accompanying drawings.

以下の説明では、本発明に係る原稿圧着板開閉保持装置を備えた事務機器として複写機を例に挙げて説明するが、本発明に係る原稿圧着板開閉保持装置を取り付け可能な事務機器としては、複写機に限らず、前記の如く、印刷機、ファクシミリ、スキャナー、その他の事務機器が広く含まれるものである。   In the following description, a copying machine will be described as an example of office equipment provided with a document crimping plate opening / closing holding device according to the present invention. In addition to copying machines, as mentioned above, printing machines, facsimiles, scanners, and other office equipment are widely included.

本発明に係る原稿圧着板開閉保持装置Ａは、図１〜図３に示したように、複写機等の事務機器１の装置本体１１に対して原稿圧着板１２をその後部において開閉可能に保持する第１開閉装置２と、原稿圧着板１２の左右いずれか一方又は双方の側辺部の前後方向の中間位置を、開閉可能に支持する第２開閉装置３と、を備えている。図１に示した実施例においては、原稿圧着板１２の左側の側辺部の中間位置が第２開閉装置３によって保持されているが、同様の構成の第２開閉装置、或は他の図示してない構成の第３開閉装置によって右側の側辺部も保持するようにしてもよい。また、原稿圧着板１２は、図示のものは原稿自動送り装置１２ａ付のものを示してあるが、原稿自動送り装置付でないものも当然に含まれる。   As shown in FIGS. 1 to 3, the document crimping plate open / close holding device A according to the present invention holds the document crimping plate 12 at its rear portion so as to be openable / closable with respect to the apparatus body 11 of the office machine 1 such as a copying machine. And a second opening / closing device 3 that supports an intermediate position in the front-rear direction of either one or both of the left and right sides of the original cover 12 so as to be openable and closable. In the embodiment shown in FIG. 1, the intermediate position of the left side portion of the original cover 12 is held by the second opening / closing device 3, but the second opening / closing device having the same configuration, or another figure. You may make it also hold | maintain the right side part by the 3rd switchgear of the structure which is not shown. Further, the document pressing plate 12 shown in the drawing is provided with an automatic document feeder 12a, but naturally, a plate not provided with an automatic document feeder is also included.

各第２開閉装置３には、後述する如く、コンプレッションスプリング３０７のような弾性手段が内蔵され、原稿圧着板１２の閉成時にこの弾性手段に蓄えられた応力が原稿圧着板１２を開成方向へ付勢するよう作用することによって、原稿圧着板１２の開成操作時に軽い力で持ち上げることができるようになっている。   As will be described later, each second opening / closing device 3 incorporates elastic means such as a compression spring 307, and the stress accumulated in the elastic means when the original cover 12 is closed causes the original cover 12 to open. By acting so as to be urged, the document crimping plate 12 can be lifted with a light force during the opening operation.

このような本発明に係る原稿圧着板開閉保持装置Ａの特徴とするところは、前記の如く、原稿圧着板１２の後部を第１開閉装置２により回動自在に保持すると共に、原稿圧着板１２の左右の側辺部の少なくとも一方の前後方向の中間位置を、原稿圧着板１２を開成方向へ付勢する第２開閉装置３によって支持するように構成したことにある。   As described above, the document crimping plate opening / closing holding device A according to the present invention is characterized in that the rear portion of the document crimping plate 12 is rotatably held by the first opening / closing device 2 and the document crimping plate 12 is also rotated. The intermediate position in the front-rear direction of at least one of the left and right side portions is supported by the second opening / closing device 3 that urges the original cover 12 in the opening direction.

本発明における第１開閉装置２は、従来の如く原稿圧着板の後部を回動可能に保持すると同時に原稿圧着板を開成方向に付勢するスプリング等による付勢機構を備えたものである必要はなく、単に原稿圧着板の後部を回動可能に保持する機能を有するもので足りる。図１〜図３に示した実施例のものは、装置本体１１側に固定される第１ブラケット２１と、原稿圧着板１２側に固定される第２ブラケット２２とがヒンジピン２３によって互いに回動可能に連結された構造のものである。   The first opening / closing device 2 according to the present invention needs to be provided with an urging mechanism by a spring or the like that urges the document crimping plate in the opening direction while simultaneously holding the rear portion of the document crimping plate rotatably. However, it is sufficient to simply have a function of holding the rear portion of the document pressing plate in a rotatable manner. In the embodiment shown in FIGS. 1 to 3, the first bracket 21 fixed to the apparatus main body 11 side and the second bracket 22 fixed to the document pressing plate 12 side can be rotated with respect to each other by the hinge pin 23. It is of a structure linked to.

但し、第１開閉装置２の構成はこれに限定されるものではなく、原稿圧着板１２を開成方向へ押し上げる付勢力の主体となる第２開閉装置３を補助する程度の付勢力を発揮するトーションスプリングやコンプレッションスプリングのような弾性手段を備えた図示してない第１開閉装置を用いるようにし、この第１開閉装置と第２開閉装置３の両方の付勢力で原稿圧着板１２を開成方向に回動させるように構成してもよい。   However, the configuration of the first opening / closing device 2 is not limited to this, and the torsion that exerts an urging force that assists the second opening / closing device 3 that is the main force of the urging force that pushes up the document pressing plate 12 in the opening direction. A first opening / closing device (not shown) provided with elastic means such as a spring or a compression spring is used, and the original pressing plate 12 is moved in the opening direction by the urging force of both the first opening / closing device and the second opening / closing device 3. You may comprise so that it may rotate.

また、本などの厚手の原稿に対応するよう原稿圧着時に原稿圧着板の後部が持ち上がるように構成した各種公知のリフト機構を有する第２開閉装置を第１開閉装置２として用いることも可能である。その場合であっても、本発明においては、原稿圧着板１２を開成方向へ持ち上げる力は、第２開閉装置３のコンプレッションスプリングのような弾性手段による付勢力を主体とし、原稿圧着板１２の後部の第１開閉装置２による付勢はあくまで補助的なものとするものである。   Further, it is also possible to use as the first opening / closing device 2 a second opening / closing device having various known lift mechanisms configured such that the rear portion of the document pressing plate is lifted when the document is pressed so as to correspond to a thick document such as a book. . Even in such a case, in the present invention, the force for lifting the document crimping plate 12 in the opening direction is mainly a biasing force by an elastic means such as a compression spring of the second opening / closing device 3, and the rear portion of the document crimping plate 12. The biasing by the first opening / closing device 2 is only auxiliary.

一方、原稿圧着板１２の左右いずれかの側辺部の中間位置を開成状態で保持する第２開閉装置３は、原稿圧着板１２を開成方向に付勢するコンプレッションスプリングやトーションスプリング等の弾性手段による付勢機構を備えていることが必要であり、その付勢力により、原稿圧着板１２の開閉操作を容易とするものである。ただ、そのような機能を備えたものであれば、この第２開閉装置３の形態は図示した実施例のものに何ら限定されず、弾性手段による付勢機構も任意である。   On the other hand, the second opening / closing device 3 that holds the intermediate position of the left or right side portion of the original cover 12 in an open state is an elastic means such as a compression spring or a torsion spring that biases the original cover 12 in the opening direction. It is necessary to provide an urging mechanism according to the above, and the urging force facilitates opening / closing operation of the original cover 12. However, as long as it has such a function, the form of the second opening / closing device 3 is not limited to that of the illustrated embodiment, and an urging mechanism using elastic means is also arbitrary.

尚、上記第２開閉装置３による原稿圧着板１２の支持位置は、原稿圧着板１２の重量によって第２開閉装置３に加わる回転モーメントを低減させる観点からすれば、なるべく原稿圧着板１２の重心に近い位置とすることが望ましいが、そうすることにより第２開閉装置３の長さが過大となる場合には、両者の関連を考慮した上で最良な位置を選定するようにする。   From the viewpoint of reducing the rotational moment applied to the second opening / closing device 3 by the weight of the document pressing plate 12, the support position of the document pressing plate 12 by the second opening / closing device 3 is as close to the center of gravity of the document pressing plate 12 as possible. Although it is desirable that the position be close, if the length of the second opening / closing device 3 becomes excessive by doing so, the best position is selected in consideration of the relationship between the two.

また、本発明における第２開閉装置３の装置本体１１に対する取付け位置においては、第２開閉装置３を装置本体１１の側面に取り付けたり、装置本体１１の上面や側面に設けた取付凹部１１ａ内に取り付けたりして、原稿圧着板１２の開閉操作の障害とならないように構成する。   Moreover, in the attachment position with respect to the apparatus main body 11 of the 2nd opening / closing apparatus 3 in this invention, the 2nd opening / closing apparatus 3 is attached to the side surface of the apparatus main body 11, or in the attachment recessed part 11a provided in the upper surface or side surface of the apparatus main body 11. It is configured so as not to obstruct the opening / closing operation of the original cover 12 by being attached.

本発明において原稿圧着板１２の側辺部の前後方向の中間位置を支持する第２開閉装置３としては、原稿圧着板１２を事務機器１の装置本体１１に対して開閉可能に支持すると共に、原稿圧着板１２の開成操作時に原稿圧着板を押し上げるよう付勢する弾性手段を備えたものであれば、各種構成のものを広く採用し得る。図４〜図６にその具体的な一実施例が示されているので、以下、これらの図を参照しつつ説明する。   In the present invention, as the second opening / closing device 3 for supporting the intermediate position in the front-rear direction of the side portion of the original cover 12, the original cover 12 is supported to be openable / closable with respect to the apparatus main body 11 of the office equipment 1. A variety of configurations can be widely used as long as they have elastic means for urging the document crimping plate to be pushed up during the opening operation of the document crimping plate 12. FIG. 4 to FIG. 6 show specific examples thereof, which will be described below with reference to these drawings.

図示した第２開閉装置３の取付部材３０１は、例えばＳＵＳのような金属プレート製の部材であり、前記事務機器１の装置本体１１上に取り付けられる。この取付部材３０１の底板３０１ｂの両側から立ち上げた両側板３０１ａ、３０１ａにヒンジシャフト３０３を介して、同じくＳＵＳのような金属プレート製の支持部材３０２の背板３０２ｂより下方へ折り曲げた両側板３０２ａ、３０２ａが回動可能に軸支されている。尚、ヒンジシャフト３０３を軸受けする取付部材３０１の図示してない軸受孔には、これも図示してないが、軸受部材が取り付けられることが好ましい。   The attachment member 301 of the illustrated second opening / closing device 3 is a member made of a metal plate such as SUS, for example, and attached to the device main body 11 of the office equipment 1.

In addition, although this is not illustrated in the bearing hole which is not illustrated of the attachment member 301 which bears the hinge shaft 303, it is preferable that a bearing member is attached.

取付部材３０１の両側板３０１ａ、３０１ａにはさらに、ヒンジシャフト３０３を取り付けた位置とは異なる位置に固定シャフト３０４が取り付けられ、この固定シャフト３０４とヒンジシャフト３０３とが挿通された形で、受圧部材３０５が取付部材３０１の両側板３０１ａ、３０１ａの間に固定されるようになっている。尚、この受圧部材３０５は固定シャフト３０４のみとしても良いし、回転するローラーとしても良い。   A fixed shaft 304 is further attached to both side plates 301a and 301a of the attachment member 301 at a position different from the position where the hinge shaft 303 is attached, and the pressure receiving member is inserted into the fixed shaft 304 and the hinge shaft 303. 305 is fixed between the side plates 301a and 301a of the mounting member 301. The pressure receiving member 305 may be only the fixed shaft 304 or a rotating roller.

支持部材３０２は、前記両側板３０２ａ、３０２ａの他に、上記したように背板３０２ｂと、頂板部３０２ｃと、抱持部３０２ｄ、３０２ｄと、前記両側板３０２ａ、３０２ａから前記頂板部３０２ｃを超えて伸張させた支持板部３０２ｉ、３０２ｉとを有している。支持板部３０２ｉ、３０２ｉの先端部側には、当該支持板部３０２ｉ、３０２ｉの間に軸架させた支持ピン３１２ａと、この支持ピン３１２ａを貫通させて回転自在に設けたローラー３１２ｂから成る支持部３１２が設けられ、この支持部３１２を原稿圧着板１２の下面側に接して取り付けたガイド部材３１３とスライド可能に係合させている。さらに支持部材３０２内部にカムスライダー３０６を摺動可能に収容し、当該カムスライダー３０６のカム面３０６ａは前記受圧部材３０５の受圧面３０５ａと当接している。 In addition to the side plates 302a and 302a, the support member 302 includes the back plate 302b, the top plate portion 302c, the holding portions 302d and 302d, and the top plate portion 302c from the side plates 302a and 302a as described above. And extended support plate portions 302i and 302i. A support pin 312a that is pivoted between the support plate portions 302i and 302i and a roller 312b that is rotatably provided through the support pin 312a are provided on the tip side of the support plate portions 302i and 302i. A portion 312 is provided, and the support portion 312 is slidably engaged with a guide member 313 attached in contact with the lower surface side of the original cover 12. Further , a cam slider 306 is slidably accommodated in the support member 302, and the cam surface 306 a of the cam slider 306 is in contact with the pressure receiving surface 305 a of the pressure receiving member 305.

カムスライダー３０６と、ショックアブソーバー３１０のフランジ部３１０ａとの間には、当該ショックアブソーバー３１０を内部に収容させてコンプレッションスプリング３０７が弾設され、カムスライダー３０６を受圧部材３０５側へ圧接させると共に、カムスライダー３０６を介して支持部材３０２を原稿圧着板１２の開成方向へ付勢させ、或は所定の閉成角度からは開成方向へ付勢させるように構成されている。   A compression spring 307 is provided between the cam slider 306 and the flange portion 310a of the shock absorber 310 so that the shock absorber 310 is accommodated therein, and the cam slider 306 is pressed against the pressure receiving member 305 side. The support member 302 is urged in the opening direction of the original cover 12 through the slider 306, or is urged in the opening direction from a predetermined closing angle.

ショックアブソーバー（流体ダンパー）３１０は、例えば公知構成のピストン式の粘性流体を用いた公知構成のものであり、そのフランジ部３１０ａは、支持部材３０２の頂板部３０２ｃに取り付けられた当接プレート３０８に当接している。当接プレート３０８の外面下方は、ストッパーピン３０９に当接せしめられ、弾性手段であるコンプレッションスプリング３０７の弾力を安定的に受ける構成である。   The shock absorber (fluid damper) 310 has a known configuration using, for example, a piston-type viscous fluid having a known configuration, and its flange portion 310 a is attached to the contact plate 308 attached to the top plate portion 302 c of the support member 302. It is in contact. The lower surface of the abutting plate 308 is configured to abut against the stopper pin 309 and stably receive the elastic force of the compression spring 307 as elastic means.

即ち、当接プレート３０８は、とくに図８に示したように、下部側を断面Ｌ字形状に折り曲げたもので、上部側に一対の係止孔３０８ａ、３０８ａと、取付孔３０８ｂが設けられ、さらに中央部に大径の挿通孔３０８ｃが設けられており、支持部材３０２の頂板部３０２ｃに設けた一対のボス部３０２ｅ、３０２ｅと係止孔３０８ａ、３０８ａを係合させた上で、取付孔３０８ｂへ挿通させたリベット３１１で頂板部３０２ｃの取付孔３０２ｇへ取り付けられると共に、当接プレート３０８の下部側はストッパーピン３０９に当接している。とくに図５と図６に示したように、支持部材３０２内のカムスライダー３０６と当接プレート３０８との間に収装されたショックアブソーバー３１０は、そのピストン杆３１０ｂの先端をカムスライダー３０６の内部に設けたボス部３０６ｂに当接させると共に、そのシリンダー部３１０ｃの端部のフランジ部３１０ａに設けたボス部３１０ｄを当接プレート３０８の挿通孔３０８ｃへ嵌入させている。尚、指示記号３０２ｈは係止孔であり、この係止孔３０２ｈは、第２開閉装置３の組立時に図示してないピンを差し込んで、カムスライダー３０６の突出を防止して、ヒンジシャフト３０３による支持部材３０２と取付部材３０１の各両側板３０２ａ、３０２ａと両側板３０１ａ、３０１ａの連結作業を容易にするためのものである。また、図９において、カムスライダー３０６の図面に指示記号３０６ｄで示した長い凹状のものはオイル溜めである。 Specifically, as shown in FIG. 8, the abutting plate 308 is formed by bending the lower side into an L-shaped cross section, and is provided with a pair of locking holes 308a and 308a and a mounting hole 308b on the upper side. Further, a large-diameter insertion hole 308c is provided at the center portion, and a pair of boss portions 302e, 302e provided on the top plate portion 302c of the support member 302 and the locking holes 308a, 308a are engaged with each other, A rivet 311 inserted into 308b is attached to the attachment hole 302g of the top plate portion 302c, and the lower side of the contact plate 308 is in contact with the stopper pin 309. In particular, as shown in FIGS. 5 and 6, the shock absorber 310 housed between the cam slider 306 and the abutting plate 308 in the support member 302 has a piston rod 310 b at the tip of the cam slider 306. The boss part 306b provided on the flange part 310a at the end of the cylinder part 310c is fitted into the insertion hole 308c of the contact plate 308. The indication symbol 302h is a locking hole. The locking hole 302h is inserted with a pin (not shown) when the second opening / closing device 3 is assembled to prevent the cam slider 306 from protruding, and the hinge shaft 303 This is for facilitating the connecting work between the side plates 302a and 302a of the support member 302 and the mounting member 301 and the side plates 301a and 301a. Also, in FIG. 9, the long concave shape indicated by the instruction symbol 306d in the drawing of the cam slider 306 is an oil sump.

さらに、本発明に係る第２開閉装置３は、とくに図７と図９に示したように、支持部材３０２の背板３０２ｂの下面に一対の凸状部３０２ｆ、３０２ｆを設けると共に、カムスライダー３０６の上面側に凸状部３０２ｆ、３０２ｆと嵌合する凹状部３０６ｃ、３０６ｃが設けられており、支持部材３０２のヒンジシャフト３０３を支点とする回動時、しかして原稿圧着板１２のとくに閉成直前にフリクション動作をすることによりブレーキ機能を営むように構成されている。 Further, the second opening / closing device 3 according to the present invention is provided with a pair of convex portions 302f and 302f on the lower surface of the back plate 302b of the support member 302, as shown in FIGS. On the upper surface side, concave portions 306c and 306c that are fitted to the convex portions 302f and 302f are provided, and when the hinge shaft 303 of the support member 302 is rotated about the fulcrum, the original cover 12 is particularly closed. It is configured to perform a brake function by performing a friction operation immediately before.

次に、本発明に係る原稿圧着板開閉保持装置Ａの作用について説明する。今、図５に示したように、原稿圧着板１２を閉じた状態においては、当該原稿圧着板１２の重量はコンプレッションスプリング３０７が原稿圧着板１２を押し上げようとする弾力よりも勝っているため、原稿圧着板１２は自己の重量で安定した閉成状態を保っている。そして、ショックアブソーバー３１０のピストン杆３１０ｂは、カムスライダー３０６のボス部３０６ｂと当接した状態にある。尚、コンプレッションスプリング３０７の作用線を受圧部材３０５の受圧面３０５ａの軸芯よりも下方へ移動させたり、或はカムスライダー３０６のカム面３０６ａの形状を変えることにより、原稿圧着板１２の開成方向へ付勢させておくことも可能である。   Next, the operation of the document crimping plate opening / closing device A according to the present invention will be described. As shown in FIG. 5, when the original cover 12 is closed, the weight of the original cover 12 is greater than the elasticity of the compression spring 307 trying to push up the original cover 12. The original cover 12 is kept in a stable closed state by its own weight. The piston rod 310b of the shock absorber 310 is in contact with the boss portion 306b of the cam slider 306. It is to be noted that the direction in which the original cover 12 is opened by moving the action line of the compression spring 307 below the axis of the pressure receiving surface 305a of the pressure receiving member 305 or changing the shape of the cam surface 306a of the cam slider 306. It is also possible to leave it energized.

図５に示した状態から原稿圧着板１２を開いて行くと、支持部材３０２はヒンジシャフト３０３を中心に回動し、コンプレッションスプリング３０７の作用線は、受圧部材３０５の受圧面３０５ａの軸芯より下方へ移動し、受圧部材３０５の受圧面３０５ａがカムスライダー３０６のカム面３０６ａと当接する箇所も、カム面３０６ａの高い方から低い方へ移動することから、コンプレッションスプリング３０７の弾力により支持部材３０２は原稿圧着板１２の開成方向へ付勢され、原稿圧着板１２はその本来の重量を減殺された状態で開かれる。   When the original cover 12 is opened from the state shown in FIG. 5, the support member 302 rotates about the hinge shaft 303, and the action line of the compression spring 307 is from the axis of the pressure receiving surface 305 a of the pressure receiving member 305. The portion that moves downward and the pressure receiving surface 305a of the pressure receiving member 305 contacts the cam surface 306a of the cam slider 306 also moves from the higher side to the lower side of the cam surface 306a, so that the support member 302 is supported by the elasticity of the compression spring 307. Is urged in the opening direction of the original cover 12 and the original cover 12 is opened with its original weight reduced.

この時、原稿圧着板１２から第２開閉装置３に掛かる回転モーメントは、「第２開閉装置３による原稿圧着板１２の支持部３１２から原稿圧着板１２の重心までの距離×原稿圧着板１２の重量」となり、これは、従来の如く原稿圧着板の後部を第２開閉装置で軸支した場合に当該第２開閉装置に掛かる原稿圧着板の回転モーメントに比べて格段に少ない値となるものである。原稿圧着板１２を開いて行くと、ショックアブソーバー３１０のピストン杆３１０ｂの先端はカムスライダー３０６のボス部３０６ｂから離脱する。   At this time, the rotational moment applied to the second opening / closing device 3 from the document crimping plate 12 is “the distance from the support 312 of the document crimping plate 12 to the center of gravity of the document crimping plate 12 by the second opening / closing device 3 × the document crimping plate 12 This is a value that is much smaller than the rotational moment of the original pressure plate applied to the second opening / closing device when the rear portion of the original pressure plate is pivotally supported by the second opening / closing device as in the prior art. is there. When the original cover 12 is opened, the tip of the piston rod 310b of the shock absorber 310 is detached from the boss 306b of the cam slider 306.

原稿圧着板１２を開いて行く過程で、第２開閉装置３による原稿圧着板１２の支持部３１２は原稿圧着板１２の側辺部の下面に沿ってスライドするが（図５、６参照）、図示した実施例のように、板金や樹脂製のガイド部材３１３を原稿圧着板１２の側辺部の下面に取り付けておくことにより、開角度規制が可能となると共に、とくに開成操作時などに第２開閉装置３の支持部３１２が原稿圧着板１２から外れたり離れたりしないようにして円滑な開閉操作をすることが可能となる。但し、このガイド部材３１３を設けることは必ずしも必須ではない。 In the process of opening the original cover 12, the support 312 of the original cover 12 by the second opening / closing device 3 slides along the lower surface of the side of the original cover 12 (see FIGS. 5 and 6 ). As shown in the illustrated embodiment, by attaching a sheet metal or resin guide member 313 to the lower surface of the side portion of the original cover 12, the opening angle can be restricted, and in particular during the opening operation. It is possible to perform a smooth opening / closing operation so that the support portion 312 of the two-opening / closing device 3 is not detached from or separated from the original cover 12. However, the provision of the guide member 313 is not always essential.

図示した実施例においては、第２開閉装置３の起立角度は約８０°となるように構成されている。   In the illustrated embodiment, the standing angle of the second opening / closing device 3 is configured to be about 80 °.

尚、第２開閉装置３の前記支持部３１２を、支持ピン３１２ａと、その外周に回転可能なように装着したローラー３１２ｂとで構成し、このローラー３１２ｂが原稿圧着板の下面と接して転動することにより、原稿圧着板１２の一層円滑な開閉動作が確保されるようにすることも推奨される。   The support portion 312 of the second opening / closing device 3 includes a support pin 312a and a roller 312b that is rotatably mounted on the outer periphery of the support pin 312a. The roller 312b rolls in contact with the lower surface of the original pressure plate. By doing so, it is also recommended that a smoother opening / closing operation of the original cover 12 is ensured.

原稿圧着板１２を閉じる際には、所定の閉成角度に近づくと、ショックアブソーバー３１０のピストン杆３１０ｂの先端がカムスライダー３０６の内頂部に当接し始め、ダンパーが効き始めることにより、支持部材３０２の回転を制御し、原稿圧着板１２が急激に閉じられるのを防止するものである。   When closing the original cover 12, when the predetermined closing angle is approached, the tip of the piston rod 310 b of the shock absorber 310 begins to abut on the inner top of the cam slider 306, and the damper begins to work, thereby supporting member 302. Is controlled to prevent the original cover 12 from being suddenly closed.

尚、上記第２開閉装置３の構成は、前記の如く、原稿圧着板１２を事務機器１の装置本体１１に対して開閉可能に支持すると共に、原稿圧着板１２の開成操作時に当該原稿圧着板１２を押し上げるよう付勢する弾性手段を備えたものであれば、各種構成のものを広く採用し得るものである。   As described above, the second opening / closing device 3 is configured such that the document crimping plate 12 is supported to be openable / closable with respect to the apparatus main body 11 of the office equipment 1 and the document crimping plate 12 is opened during the opening operation. As long as it has an elastic means for urging to push up 12, various configurations can be widely adopted.

また、本発明に係る事務機器（例えば、複写機、印刷機、ファクシミリ、スキャナー、その他の事務機器を含む。）１は、本発明に係る上記の如き原稿圧着板開閉保持装置Ａを備えてなるものであり、本発明に係る原稿圧着板開閉保持装置Ａの前記の如き利点を生かした事務機器となるものである。   Further, office equipment (for example, a copier, a printing machine, a facsimile, a scanner, and other office equipment) 1 according to the present invention includes the above-described document crimping plate opening and closing device A according to the present invention. Therefore, it is an office machine that takes advantage of the above-described advantages of the document crimping plate opening / closing device A according to the present invention.

さらにまた、前記の如く構成される本発明に係る原稿圧着板開閉保持装置Ａは、事務機器１等のメンテナンス時に、装置本体１１と原稿圧着板１２との間にアタッチメントとして一時的に取り付けて、原稿圧着板１２を開閉可能に保持する開閉装置として好適に使用することができる。その場合においても、前記第２開閉装置３が小型で低価格のもので済むので、好都合である。   Furthermore, the document crimping plate opening and closing device A according to the present invention configured as described above is temporarily attached as an attachment between the apparatus main body 11 and the document crimping plate 12 during maintenance of the office equipment 1 or the like. It can be suitably used as an opening / closing device that holds the original cover 12 in an openable / closable manner. Even in this case, the second opening / closing device 3 is convenient because it is small and inexpensive.

以上は、第１開閉装置２と第２開閉装置３を共動させて原稿圧着板１２を開閉させる場合について説明したが、第２開閉装置３を装置本体１１の修理時やメンテナンス時に使用する場合について説明する。この場合には、ガイド部材３１３を廃し、支持部材３０２の支持部３１２は原稿圧着板１２に対しフリーな状態にした上で、原稿圧着板１２を閉じた状態において、図示してない係止ピン或は係止部材を用いて支持部材３０２を取付部材３０１に係止させるか、支持部材３０２を装置本体１１へ係止させておき、使用時に係止ピン或は係止部材による支持部材３０２に対する係止を解いて当該支持部材３０２の先端側のローラー３１２ｂで原稿圧着板１２の下面と接するようにして、開いた原稿圧着板１２を開成状態で自然落下しないように保持するものである。   Although the case where the first opening / closing device 2 and the second opening / closing device 3 are moved together to open / close the original cover 12 has been described above, the second opening / closing device 3 is used for repairing or maintaining the apparatus body 11. Will be described. In this case, the guide member 313 is eliminated, and the support portion 312 of the support member 302 is free from the original cover 12 and the original cover 12 is closed. Alternatively, the support member 302 is locked to the mounting member 301 by using a locking member, or the support member 302 is locked to the apparatus main body 11, and the locking pin or the locking member is used for the support member 302 during use. Unlocking is performed so that the roller 312b on the front end side of the support member 302 is in contact with the lower surface of the original cover 12 and the open original cover 12 is held in an open state so as not to fall naturally.

上述の如き構成を有する本発明は、第１開閉装置の構成を簡単なものにしても、第２開閉装置によって、原稿圧着板を開成状態で安定的に保持できることから、原稿圧着板を開いた状態での事務機器の装置本体の修理作業やメンテナンス作業を支障なく行うことができることから、比較的小型で安価な機種の事務機器の原稿圧着板開閉保持装置として好適に用いられるものである。   In the present invention having the above-described configuration, even if the configuration of the first opening / closing device is simplified, the document pressing plate can be stably held in the open state by the second opening / closing device. Since the repair work and maintenance work of the apparatus main body of the office equipment in the state can be performed without hindrance, the apparatus is suitably used as a document crimping plate opening and closing holding apparatus of a relatively small and inexpensive model of office equipment.
