Description

本発明は画像形成装置の下部に増設されるオプション装置に関し、詳しくはオプション装置に設けられた画像形成装置の転倒防止機構に関する。   The present invention relates to an optional device added to the lower part of an image forming apparatus, and more particularly to a fall prevention mechanism for an image forming apparatus provided in the optional device.

従来、複写機やプリンタ等の本体装置の下部に反転装置や給紙装置等のオプション装置が付設された構成が知られている。このようにオプション装置の上部に本体装置を設置して結合する場合、オプション装置の上面に長い２本の位置決めピンを突出させてこれらを本体装置の底面に形成された位置決め孔に嵌合させることにより、本体装置を位置決めすると共に本体装置の転倒防止を図っている。   2. Description of the Related Art Conventionally, a configuration is known in which optional devices such as a reversing device and a paper feeding device are attached to the lower part of a main body device such as a copying machine or a printer. When the main unit is installed and coupled to the upper part of the optional device in this way, two long positioning pins protrude from the upper surface of the optional device and are fitted in positioning holes formed on the bottom surface of the main unit. Thus, the main unit is positioned and the main unit is prevented from falling.

しかし、本体装置の転倒を防止する高さや太さに位置決めピンを構成することは製品構成上難しい場合があり、また上面に本体装置を載置していない状態ではピンが突出した状態で露出しており危険であるという問題点がある。そこで、本体装置を載置するとこの載置動作に連動してロックが解除されてオプション装置から転倒防止部材が突出し、画像形成装置の底面に形成された凹部に嵌合する技術が、例えば「特許文献１」に開示されている。   However, it may be difficult in terms of product configuration to configure the positioning pin at a height or thickness that prevents the main unit from toppling over, and when the main unit is not placed on the top surface, the pin protrudes and is exposed. There is a problem that it is dangerous. Accordingly, when the main body device is placed, the lock is released in conjunction with the placement operation, the fall prevention member protrudes from the optional device, and the technology for fitting into the recess formed on the bottom surface of the image forming apparatus is, for example, “patent Reference 1 ”.

しかし上述の技術では、オプション装置への本体装置の載置動作に連動して転倒防止部材が必ず突出するため、オプション装置の取り外しを行いたいユーザに対しても転倒防止部材が突出してオプション装置と本体装置とが連結されていることから、オプション装置の取り外しが容易に行えずに作業性が悪いという問題点がある。
本発明は上述の問題点を解決し、必要なときに転倒防止機能を発現させることが可能なオプション装置及びこれを備えた画像形成システムの提供を目的とする。 However, in the above-described technique, the fall prevention member always protrudes in conjunction with the mounting operation of the main body device on the option device. Since the main unit is connected, there is a problem that the optional device cannot be easily removed and the workability is poor.
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems, and to provide an optional device capable of exhibiting a fall prevention function when necessary and an image forming system provided with the optional device.

請求項１記載の発明は、本体装置の下方に配置されその上面上に前記本体装置が載置されるオプション装置であって、前記上面より上方に突出する突出位置と前記上面より下方に格納される格納位置とを選択的に占め前記突出位置において前記本体装置と係合する係合部材と、前記係合部材を前記突出位置に向けて付勢する付勢部材と、前記係合部材が前記突出位置を占めることを規制する規制部材とを有し、前記規制部材による前記係合部材の突出規制を解除することにより前記係合部材が前記突出位置を占めることを特徴とする。   The invention according to claim 1 is an optional device that is arranged below the main body device and on which the main body device is placed, and is stored below the upper surface and a protruding position that protrudes above the upper surface. An engagement member that selectively occupies the retracted position and engages the main body device at the protruding position, a biasing member that biases the engaging member toward the protruding position, and And a restricting member for restricting occupying the protruding position, and the engaging member occupies the protruding position by releasing the protrusion restriction of the engaging member by the restricting member.

本発明によれば、転倒防止機能をユーザの要望に合わせて発現させることができ、本体装置とオプション装置とを早急に取り外したい場合には転倒防止機構を作動させずに両者を結合させ、本体装置とオプション装置とを取り外す必要がない場合には転倒防止機構を作動させて両者を結合させることができ、作業性の向上を図ることができると共に本体装置の転倒防止を図ることができる。   According to the present invention, the fall prevention function can be developed according to the user's request, and when it is desired to quickly remove the main body device and the optional device, the main body device and the optional device are combined without operating the fall prevention mechanism. When it is not necessary to remove the device and the optional device, the overturn prevention mechanism can be operated to couple them together, so that workability can be improved and the main body device can be prevented from overturning.

The recording paper is discharged from an opening (not shown) provided on the upper surface of the paper feeding device 2 and sent to the paper feeding path inside the printer 1 from the opening of the printer 1 communicating therewith.

さらに給紙装置２の上面には、プリンタ１と給紙装置２との位置決めを行う位置決めピン３、プリンタ１の転倒を防止する転倒防止機構４が配設されている。位置決めピン３は給紙装置２の左右に１本ずつ計２本設けられており、プリンタ１の底面には各ピン３が嵌合する図示しない嵌合孔が２箇所穿設されている。転倒防止機構４は給紙装置２の左右に計３箇所設けられており、プリンタ１の側面内部には後述する係合部材と係合する穴部を有する連結部材８が、係合部材と対応してそれぞれ設けられている。   Further, a positioning pin 3 for positioning the printer 1 and the paper feeding device 2 and a tipping prevention mechanism 4 for preventing the printer 1 from tipping over are provided on the upper surface of the paper feeding device 2. Two positioning pins 3 are provided on the left and right sides of the sheet feeding device 2 in total, and two fitting holes (not shown) into which the pins 3 are fitted are formed on the bottom surface of the printer 1. The fall prevention mechanism 4 is provided at a total of three locations on the left and right sides of the paper feeding device 2, and a connecting member 8 having a hole portion that engages with an engaging member described later corresponds to the engaging member inside the side surface of the printer 1. And each is provided.

転倒防止機構４は、図３及び図４に示すように、規制部材としてのスライド板５と係合部材６とを有している。スライド板５は、図３に示す矢印方向に移動自在となるように給紙装置２の上面に設けられており、図３に示す閉塞位置とここから図３において左方へと移動した開放位置とを占める。スライド板５には、図４に示すように一端を給紙装置２の装置本体に固定された圧縮ばね９の他端が取り付けられており、スライド板５は常時閉塞位置へと付勢されている。   As shown in FIGS. 3 and 4, the overturn prevention mechanism 4 includes a slide plate 5 and an engagement member 6 as regulating members. The slide plate 5 is provided on the upper surface of the sheet feeding device 2 so as to be movable in the direction of the arrow shown in FIG. 3, and is in the closed position shown in FIG. 3 and the open position moved to the left in FIG. And occupy. As shown in FIG. 4, the slide plate 5 is attached with the other end of a compression spring 9 having one end fixed to the main body of the paper feeding device 2, and the slide plate 5 is always urged to the closed position. Yes.

スライド板５の下方に位置する給紙装置２の内部には係合部材６が配設されている。側面視Ｌ字形状の板材からなる係合部材６は給紙装置２の内部に設けられたガイド軸１１に沿って上下動自在に設けられており、その下方に設けられた付勢部材としての圧縮ばね７によって上方に向けて付勢されている。係合部材６は、スライド板５が閉塞位置を占めているときにはその上端をスライド板５に当接させていて図４に示す格納位置を占めている。   An engaging member 6 is disposed inside the paper feeding device 2 located below the slide plate 5. The engaging member 6 made of a plate material having an L-shape when viewed from the side is provided so as to be movable up and down along a guide shaft 11 provided inside the sheet feeding device 2 and serves as an urging member provided below the engaging shaft 6. It is biased upward by the compression spring 7. When the slide plate 5 occupies the closed position, the engaging member 6 has its upper end in contact with the slide plate 5 and occupies the storage position shown in FIG.

図４に示した状態からスライド板５が圧縮ばね９の付勢力に抗して図３の矢印方向に移動されると、圧縮ばね７によって付勢された係合部材６がガイド軸１１に沿って上方へと移動して図５及び図６に示す突出位置を占める。図４及び図６における符号１２は、係合部材６が上方へと移動してガイド軸１１より外れてしまうことを防止するためのストッパである。ストッパ１２は給紙装置２の図示しない装置本体に固設されており、ストッパ１２の上面に沿ってスライド板５が移動可能となるように構成されている。係合部材６には、突出位置を占めた際に連結部材８に設けられた穴部と対応する位置に穴部が設けられている。   When the slide plate 5 is moved in the direction of the arrow in FIG. 3 against the urging force of the compression spring 9 from the state shown in FIG. 4, the engaging member 6 urged by the compression spring 7 moves along the guide shaft 11. It moves upward and occupies the protruding position shown in FIGS. Reference numeral 12 in FIGS. 4 and 6 is a stopper for preventing the engaging member 6 from moving upward and coming off the guide shaft 11. The stopper 12 is fixed to a main body (not shown) of the paper feeding device 2, and is configured such that the slide plate 5 can move along the upper surface of the stopper 12. The engaging member 6 is provided with a hole at a position corresponding to the hole provided in the connecting member 8 when the protruding position is occupied.

上述した係合部材６の格納位置から突出位置への移動時において、スライド板５が閉塞位置から移動されて係合部材６の上端とスライド板５との係合が解除されると圧縮ばね７によって付勢された係合部材６が上方へと突出するが、このときスライド板５は圧縮ばね９によって閉塞位置に向けて付勢されているために突出する係合部材６はスライド板５の自由端部と接触することとなり、係合部材６が突出位置を占める際にスライド板５がガイドとして機能する。また、係合部材６が突出位置を占めた後も係合部材６はスライド板５の自由端部と接触しているため、スライド板５は係合部材６が図６において左方へと倒れることを抑制して突出位置を保持するように機能する。   When the slide plate 5 is moved from the closed position and the engagement between the upper end of the engagement member 6 and the slide plate 5 is released during the movement of the engagement member 6 from the retracted position to the protruding position, the compression spring 7. The engaging member 6 urged by the projection protrudes upward. At this time, since the slide plate 5 is urged toward the closed position by the compression spring 9, the projecting engagement member 6 of the slide plate 5 is When the engaging member 6 occupies the protruding position, the slide plate 5 functions as a guide. Further, since the engaging member 6 is in contact with the free end portion of the slide plate 5 even after the engaging member 6 occupies the protruding position, the slide plate 5 is tilted to the left in FIG. It functions to suppress this and hold the protruding position.

上述の構成を画像形成システム１０として見ると、スライド板５が閉塞位置を占めて係合部材６が格納位置を占めている状態は図７に示すようであり、この状態からスライド板５が移動されて係合部材６が突出位置を占めると図８に示す状態となる。図８に示した状態では、突出した係合部材６が連結部材８と係合（本実施形態では互いに重なり合った状態をいう）してそれぞれの穴部が重なり合って（装置外側に係合部材６が位置している）いる。この状態で、例えば連結部材８の裏側（装置内側）にナットを固定しておき、画像形成装置１の外装上から係合部材６及び連結部材８を介してナットにねじを螺合させることによりプリンタ１と給紙装置２とが完全に連結され、プリンタ１のみを持ち上げてもプリンタ１と給紙装置２との連結（係合）状態が解除されない。   When the above-described configuration is viewed as the image forming system 10, the state where the slide plate 5 occupies the closed position and the engaging member 6 occupies the storage position is as shown in FIG. 7, and the slide plate 5 moves from this state. When the engaging member 6 occupies the protruding position, the state shown in FIG. 8 is obtained. In the state shown in FIG. 8, the protruding engaging member 6 engages with the connecting member 8 (in the present embodiment, it refers to a state where they overlap each other), and the respective hole portions overlap (the engaging member 6 on the outside of the apparatus). Is located). In this state, for example, a nut is fixed to the back side (inside the apparatus) of the connecting member 8, and a screw is screwed onto the nut from the exterior of the image forming apparatus 1 via the engaging member 6 and the connecting member 8. The printer 1 and the paper feeding device 2 are completely connected. Even if only the printer 1 is lifted, the connected (engaged) state between the printer 1 and the paper feeding device 2 is not released.

上述の構成ではスライド板５の閉塞位置からの移動手段について具体的な構成を挙げなかったが、移動手段は手動でも自動でもよい。手動で移動させる場合には、プリンタ１の載置前においては単にスライド板５を開放させ、プリンタ１の載置後にはピン等を用いてプリンタ１の外装に設けられた図示しない穴部よりピンを挿入させてスライド板５の切欠部にこれを係合させて開放させる。自動で移動させる場合には、モータやシリンダ等のアクチュエータをスライド板５に接続させておき、プリンタ１または給紙装置２に設けられたスイッチによってこのアクチュエータを作動させる。   In the above-described configuration, no specific configuration is given for the moving means from the closed position of the slide plate 5, but the moving means may be manual or automatic. When the printer 1 is moved manually, the slide plate 5 is simply opened before the printer 1 is placed, and after the printer 1 is placed, a pin or the like is used to insert a pin from a hole (not shown) provided in the exterior of the printer 1. Is inserted into the notch of the slide plate 5 and released. In the case of automatic movement, an actuator such as a motor or a cylinder is connected to the slide plate 5, and this actuator is operated by a switch provided in the printer 1 or the paper feeder 2.

上述の構成によれば、転倒防止機構４をユーザの要望に合わせて機能させることができ、プリンタ１と給紙装置２とを早急に取り外したい場合には転倒防止機構４を作動させずに両者を結合させ、プリンタ１と給紙装置２とを取り外す必要がない場合には転倒防止機構４を作動させて両者を結合させることができ、作業性の向上を図ることができると共にプリンタ１の転倒防止を図ることができる。   According to the above-described configuration, the fall prevention mechanism 4 can be made to function in accordance with the user's request, and both the printer 1 and the paper feeding device 2 can be removed without activating the fall prevention mechanism 4 when it is desired to remove them immediately. When the printer 1 and the paper feeding device 2 do not need to be detached, the overturn prevention mechanism 4 can be operated to couple the two, so that the workability can be improved and the printer 1 can be overturned. Prevention can be achieved.

さらに上述の構成において、突出位置を占めている係合部材６を格納位置へと埋没させる埋没手段を設けてもよい。埋没手段としては、例えば係合部材６に、側方へと延出してプリンタ１及び給紙装置２の外装を介して突出したレバーを設け、このレバーを把持して圧縮ばね７の付勢力に抗して係合部材６を格納位置へと埋没させる構成が挙げられる。この埋没手段を設けることにより、上述した実施形態の作用効果に加え、プリンタ１と給紙装置２との転倒防止機構４による連結を、プリンタ１を持ち上げることなく簡単に解除することができ、作業性を向上させることができる。   Furthermore, in the above-described configuration, a burying means for burying the engaging member 6 occupying the protruding position into the retracted position may be provided. As the burying means, for example, a lever that extends laterally and protrudes through the exterior of the printer 1 and the paper feeding device 2 is provided on the engaging member 6, and this lever is gripped to apply the biasing force of the compression spring 7. There is a configuration in which the engaging member 6 is buried in the retracted position. By providing this burying means, in addition to the effects of the above-described embodiment, the connection between the printer 1 and the paper feeding device 2 by the fall prevention mechanism 4 can be easily released without lifting the printer 1. Can be improved.
