Description

この発明は、装置本体に開閉自在に支持された第１扉及び第２扉を備える扉解除装置及びこれを備えたシート搬送装置に関する。   The present invention relates to a door release device including a first door and a second door that are supported by an apparatus main body so as to be freely opened and closed, and a sheet conveying device including the door release device.

複写機、プリンタ、ファクシミリ装置、及びこれらの複合機のようにシートに処理を施す画像形成装置は、シート搬送装置を備えている。シート搬送装置の中には、シート搬送路の互いに異なる箇所に設けられる第１扉及び第２扉を含む扉解除装置を備えるものがある。第１扉及び第２扉は、扉解除装置の装置本体に開閉自在に支持される。第１扉及び第２扉のそれぞれが装置本体の外装部材の一部を構成する位置に保持された閉鎖状態において、第１扉及び第２扉のそれぞれと装置本体との間にシート搬送路が構成される。また、第１扉及び第２扉が閉鎖状態から解除されて開放自在にされた解除状態において、各扉を開放することで、その扉の設置箇所のシート搬送路が露出され、シート詰まりを解消するジャム処理が容易になる。このような複数の扉を含む扉解除装置では、複数の扉を閉鎖状態から解除状態にすることを１個の操作部材で行うことができれば、操作性が向上する。   Image forming apparatuses that process sheets, such as copiers, printers, facsimile machines, and multi-function machines, include a sheet conveying device. Some sheet conveying apparatuses include a door releasing device including a first door and a second door provided at different locations on the sheet conveying path. The first door and the second door are supported by the device body of the door release device so as to be opened and closed. In the closed state in which each of the first door and the second door is held at a position constituting a part of the exterior member of the apparatus main body, a sheet conveyance path is provided between each of the first door and the second door and the apparatus main body. Composed. In addition, in the released state where the first door and the second door are released from the closed state and opened freely, the sheet conveyance path at the location where the door is installed is exposed and the sheet jam is eliminated. Jam processing is easy. In such a door release device including a plurality of doors, if the plurality of doors can be changed from the closed state to the released state with a single operation member, the operability is improved.

そこで、装置本体からの扉の固定解除と扉からの搬送路ユニットの固定解除とを１個の操作部材で行うことができるように構成された画像形成装置が知られている（例えば、特許文献１参照。）。   Therefore, an image forming apparatus configured to be able to perform unlocking of the door from the apparatus main body and unlocking of the conveyance path unit from the door with a single operation member is known (for example, Patent Document 1). 1).

特開２００９−２２３２０３号公報JP 2009-223203 A

しかし、特許文献１に記載の従来技術では、扉の開閉軸と搬送路ユニットの開閉軸とが平行であり、それぞれの開閉軸が互いに異なる方向に配置された第１扉及び第２扉を含む扉解除装置に従来技術を適用することは不可能又はどのようにして適用できるのか不明である。このため、従来技術では、第１扉及び第２扉の設置方向が、開閉軸が平行になる方向に限定されてしまう。よって、扉の設置箇所に応じて作業がしやすい方向に開閉するように各扉を設置することができず、各扉の開放後の作業性が低下する。   However, in the prior art described in Patent Document 1, the opening / closing axis of the door and the opening / closing axis of the transport path unit are parallel, and each opening / closing axis includes a first door and a second door arranged in different directions. It is not possible or impossible to apply the prior art to the door release device. For this reason, in the related art, the installation direction of the first door and the second door is limited to a direction in which the opening / closing axis is parallel. Therefore, each door cannot be installed so that it can be opened and closed in a direction in which it is easy to work according to the installation location of the door, and workability after opening each door is reduced.

この発明の目的は、第１扉及び第２扉を閉鎖状態から解除状態にする操作性及び各扉の開放後の作業性を向上できる扉解除装置及びこれを備えたシート搬送装置を提供することにある。   An object of the present invention is to provide a door release device that can improve the operability of bringing the first door and the second door from the closed state to the released state and the workability after opening the doors, and a sheet conveying device including the door release device. It is in.

この発明の扉解除装置は、装置本体、第１扉及び第２扉、操作部材、並びに解除機構部を備える。第１扉及び第２扉は、装置本体に開閉自在に支持される。第１扉の開閉軸と第２扉の開閉軸とは互いに異なる方向に配置される。操作部材は、基準位置、第１解除位置、及び第２解除位置に変位自在に装置本体に取り付けられる。解除機構部は、第１扉及び第２扉のそれぞれを装置本体の外装部材の一部を構成する位置に保持された閉鎖状態と閉鎖状態から解除されて開放自在にされた解除状態とに移行させる。解除機構部は、操作部材が基準位置にある状態では第１扉及び第２扉の両方を閉鎖状態にし、操作部材が基準位置から第１解除位置へ操作されると第１扉のみを解除状態にし、操作部材が第１解除位置から第２解除位置へ操作されると第１扉に加えてさらに第２扉も解除状態にする。   The door release device of the present invention includes an apparatus main body, a first door and a second door, an operation member, and a release mechanism. The first door and the second door are supported by the apparatus main body so as to be freely opened and closed. The opening / closing axis of the first door and the opening / closing axis of the second door are arranged in different directions. The operation member is attached to the apparatus main body so as to be displaceable to a reference position, a first release position, and a second release position. The release mechanism portion shifts between a closed state in which each of the first door and the second door is held at a position constituting a part of the exterior member of the apparatus main body and a release state in which the release is released from the closed state and freely opened. Let The release mechanism part closes both the first door and the second door when the operation member is at the reference position, and releases the first door only when the operation member is operated from the reference position to the first release position. When the operating member is operated from the first release position to the second release position, the second door is also released in addition to the first door.

この構成では、それぞれの開閉軸が互いに異なる方向に配置された第１扉と第２扉とが、１個の操作部材を操作することで、個別に閉鎖状態から解除状態に移行される。即ち、１個の操作部材を操作することで、第１扉のみの解除と、第１扉及び第２扉の両方の解除とを、ユーザが任意に行うことができる。また、第１扉及び第２扉の設置箇所に応じて第１扉及び第２扉のそれぞれの開放後の作業性がよくなる方向に第１扉及び第２扉が開くように、第１扉及び第２扉を設置することができる。   In this configuration, the first door and the second door in which the respective opening and closing shafts are arranged in different directions are individually shifted from the closed state to the released state by operating one operation member. That is, by operating one operation member, the user can arbitrarily release only the first door and release both the first door and the second door. In addition, the first door and the second door are opened in a direction in which the workability after opening the first door and the second door is improved according to the installation location of the first door and the second door. A second door can be installed.

上述の構成において、解除機構部は、装置本体に配置され、操作部が基準位置から第１解除位置へ、及び第１解除位置から第２解除位置へ操作されるのにともなって、第１軸方向を中心に第１周方向へ回転する第１軸部材と、装置本体に第１軸部材とは異なる方向に配置され、第２軸方向を中心に回転自在に構成された第２軸部材と、第１軸部材と第２軸部材とに設けられた一対の傾斜カムであって第１軸部材の第１周方向への回転にともなって第２軸部材を第２周方向へ回転させる一対の傾斜カムとを有するように構成することができる。   In the above-described configuration, the release mechanism unit is disposed in the apparatus main body, and the first shaft is operated as the operation unit is operated from the reference position to the first release position and from the first release position to the second release position. A first shaft member that rotates in the first circumferential direction about the direction, and a second shaft member that is disposed in the apparatus main body in a direction different from the first shaft member and is configured to be rotatable about the second axis direction. A pair of inclined cams provided on the first shaft member and the second shaft member, wherein the second shaft member rotates in the second circumferential direction as the first shaft member rotates in the first circumferential direction. It can comprise so that it may have an inclination cam.

この構成では、第１軸部材と第２軸部材とは互いに異なる方向に配置されるが、第１軸部材の第１周方向への回転が、第２軸部材の第２周方向への回転に、一対の傾斜カムによって回転軸方向を変換されて伝達される。このため、第１軸部材で第１扉を閉鎖状態から解除状態にし、第２軸部材で第２扉を閉鎖状態から解除状態にするように構成することで、開閉軸が互いに異なる方向に配置される２個の扉を、第１軸部材を回転させるように操作するだけで閉鎖状態から解除状態にすることができる。   In this configuration, the first shaft member and the second shaft member are arranged in different directions, but the rotation of the first shaft member in the first circumferential direction is the rotation of the second shaft member in the second circumferential direction. In addition, the rotation axis direction is converted by the pair of inclined cams and transmitted. For this reason, the first door is opened from the closed state by the first shaft member, and the second door is released from the closed state by the second shaft member, so that the opening and closing shafts are arranged in different directions. The two doors can be changed from the closed state to the released state simply by operating the first shaft member to rotate.

また、解除機構部は、第１基端部及び第１係止部を有し、第１基端部は第１軸部材に固定され、第１係止部は、操作部材が基準位置にある状態では閉鎖状態の第１扉に係止し、操作部材が第１解除位置に配置されると第１扉との係止が解除されるように構成された第１係止部材と、第２基端部及び第２係止部を有し、第２基端部は第２軸部材に固定され、第２係止部は、操作部材が基準位置及び第１解除位置にある状態では閉鎖状態の第２扉に係止し、操作部材が第２解除位置に配置されると第２扉との係止が解除されるように構成された第２係止部材とをさらに有するように構成することができる。   Further, the release mechanism portion has a first base end portion and a first locking portion, the first base end portion is fixed to the first shaft member, and the operation member is at the reference position of the first locking portion. A first locking member configured to be locked to the closed first door in the state, and to be unlocked from the first door when the operation member is disposed at the first release position; A second end portion is fixed to the second shaft member, and the second end portion is closed when the operation member is in the reference position and the first release position. And a second locking member configured to be unlocked when the operating member is disposed at the second release position. be able to.

この構成では、操作部材を基準位置、第１解除位置、第２解除位置へと操作することで、第１軸部材が回転し、まず第１扉のみが閉鎖状態から解除状態になり、その後、第２扉も閉鎖状態から解除状態になる。このように、１個の操作部材を操作することで、２個の扉を閉鎖状態から解除状態にすることができる。   In this configuration, by operating the operation member to the reference position, the first release position, and the second release position, the first shaft member rotates, and only the first door is changed from the closed state to the released state, and then The second door is also released from the closed state. In this way, by operating one operating member, the two doors can be released from the closed state.

さらに、一対の傾斜カムは、操作部材が基準位置にある状態では互いに離間し、操作部材が第１解除位置から第２解除位置へ操作されると一方が他方を押圧して第２軸部材を第２周方向へ回転させるように構成することができる。   Further, the pair of inclined cams are separated from each other when the operation member is at the reference position, and when the operation member is operated from the first release position to the second release position, one of the two cams presses the other to push the second shaft member. It can be configured to rotate in the second circumferential direction.

この構成では、操作部材を基準位置から第１解除位置へ操作する間は、第１軸部材は回転するが第１軸部材の回転が第２軸部材へ伝達されず、操作部材が第１解除位置に配置されると一対の傾斜カムが互いに接触し、操作部材を第１解除位置から第２解除位置へ操作するときに第１軸部材の回転が第２軸部材へ伝達される。このため、操作部材を基準位置、第１解除位置、第２解除位置へと変位させる一連の操作をすることで、第２軸部材の回転開始タイミングを第１軸部材の回転開始タイミングから遅らせることができる。これによって、第１扉が閉鎖状態から解除状態にされるタイミングから、第２扉が閉鎖状態から解除状態にされるタイミングを、遅らせることができる。   In this configuration, while the operation member is operated from the reference position to the first release position, the first shaft member rotates, but the rotation of the first shaft member is not transmitted to the second shaft member, and the operation member is first released. When arranged at the position, the pair of inclined cams come into contact with each other, and the rotation of the first shaft member is transmitted to the second shaft member when the operation member is operated from the first release position to the second release position. For this reason, the rotation start timing of the second shaft member is delayed from the rotation start timing of the first shaft member by performing a series of operations to displace the operation member to the reference position, the first release position, and the second release position. Can do. Accordingly, the timing at which the second door is changed from the closed state to the released state can be delayed from the timing at which the first door is changed from the closed state to the released state.

また、一対の傾斜カムは、操作部材が基準位置にある状態で互いに接触し、操作部材が基準位置にある状態から第２扉との係止が解除されるまでの第２係止部の変位長さは、操作部材が基準位置にある状態から第１扉との係止が解除されるまでの第１係止部の変位長さよりも長いように構成することができる。   The pair of inclined cams contact each other with the operating member in the reference position, and the second locking portion is displaced from the state in which the operating member is in the reference position until the locking with the second door is released. The length can be configured to be longer than the displacement length of the first locking portion from when the operating member is in the reference position to when the locking with the first door is released.

この構成では、第１軸部材の回転開始タイミングと第２軸部材の回転開始タイミングとは同じであるが、第１軸部材及び第２軸部材の回転開始タイミングから、第１係止部と第１扉との係止が解除されるまでの時間よりも、第２係止部と第２扉との係止が解除されるまでの時間の方が、長くなる。これによって、第１扉が閉鎖状態から解除状態にされるタイミングから、第２扉が閉鎖状態から解除状態にされるタイミングを、遅らせることができる。   In this configuration, the rotation start timing of the first shaft member and the rotation start timing of the second shaft member are the same, but from the rotation start timing of the first shaft member and the second shaft member, The time until the locking between the second locking portion and the second door is released is longer than the time until the locking with the one door is released. Accordingly, the timing at which the second door is changed from the closed state to the released state can be delayed from the timing at which the first door is changed from the closed state to the released state.

さらに、操作部材は、装置本体の内部へ向けて押し込まれるように構成することができる。   Furthermore, the operation member can be configured to be pushed toward the inside of the apparatus main body.

この構成では、操作部材を押し込んでいない位置が基準位置、少し押し込んだ位置が第１解除位置、さらに押し込んだ位置が第２解除位置に設定される。このように、１個の操作部材を一方向に操作することで、２個の扉を個別に閉鎖状態から解除状態へ移行させることができ、操作性がよい。   In this configuration, a position where the operation member is not pushed in is set as a reference position, a position where the operation member is pushed slightly is set as a first release position, and a position where the operation member is pushed further is set as a second release position. In this way, by operating one operating member in one direction, the two doors can be individually shifted from the closed state to the released state, and the operability is good.

また、操作部材は、外装部材に沿ってスライドするように構成することができる。   The operation member can be configured to slide along the exterior member.

この構成では、操作部材を外装部材に沿ってスライドさせた各位置に、基準位置、第１解除位置、及び第２解除位置が設定され、操作部材を外装部材に沿ってスライドさせることで、第１軸部材が回転するように構成される。この構成においても、１個の操作部材を一方向に操作することで、２個の扉を個別に閉鎖状態から解除状態へ移行させることができ、操作性がよい。   In this configuration, the reference position, the first release position, and the second release position are set at each position where the operation member is slid along the exterior member, and the operation member is slid along the exterior member, The uniaxial member is configured to rotate. Also in this configuration, by operating one operation member in one direction, the two doors can be individually shifted from the closed state to the released state, and operability is good.

この発明のシート搬送装置は、上述のいずれかの構成の扉解除装置と、閉鎖状態における第１扉及び第２扉のそれぞれと装置本体との間でシートを搬送するように構成されたシート搬送路とを備える。   A sheet conveying apparatus according to the present invention is configured to convey a sheet between the door releasing device having any one of the above-described configurations, and each of the first door and the second door in the closed state and the apparatus main body. Road.

この構成では、それぞれの開閉軸が互いに異なる方向に配置された第１扉と第２扉とが、１個の操作部材を操作することで、個別に閉鎖状態から解除状態に移行される。即ち、１個の操作部材を操作することで、第１扉のみの解除と、第１扉及び第２扉の両方の解除とを、ユーザが任意に行うことができる。また、第１扉及び第２扉の設置箇所に応じて第１扉及び第２扉のそれぞれの開放後の作業性がよくなる方向に第１扉及び第２扉が開くように、第１扉及び第２扉を設置することができる。   In this configuration, the first door and the second door in which the respective opening and closing shafts are arranged in different directions are individually shifted from the closed state to the released state by operating one operation member. That is, by operating one operation member, the user can arbitrarily release only the first door and release both the first door and the second door. In addition, the first door and the second door are opened in a direction in which the workability after opening the first door and the second door is improved according to the installation location of the first door and the second door. A second door can be installed.

この発明によれば、第１扉及び第２扉を閉鎖状態から解除状態にする操作性及び各扉の開放後の作業性を向上させることができる。   According to this invention, the operativity which makes a 1st door and a 2nd door a release state from a closed state, and the workability | operativity after each door open | release can be improved.

The upper surfaces of the first door 30 and the second door 40 constitute a paper discharge tray 112. Further, a relay paper conveyance path 116 is formed between the first door 30 and the second door 40 in the closed state and the upper surface of the apparatus main body 20.

伝達部材５０は操作ボタン５１を有し、操作ボタン５１は、装置本体２０の上面の正面側端部に、装置本体２０の内部へ向けて押し込むことができるように構成されている。操作ボタン５１は、この発明の操作部材に相当する。   The transmission member 50 includes an operation button 51, and the operation button 51 is configured to be able to be pushed into the front end portion of the upper surface of the apparatus body 20 toward the inside of the apparatus body 20. The operation button 51 corresponds to the operation member of the present invention.

図５、図６、及び図７に示すように、解除機構部６０は、第１軸部材６１、第２軸部材６２、一対の傾斜カム６３，６４、第１係止部材６５，６６、第２係止部材６７を備えている。   As shown in FIGS. 5, 6, and 7, the release mechanism 60 includes a first shaft member 61, a second shaft member 62, a pair of inclined cams 63 and 64, first locking members 65 and 66, Two locking members 67 are provided.

第１軸部材６１は、第１軸方向が用紙搬送方向Ｘに平行になるように装置本体２０の正面側端部に配置され、第１軸方向を中心に回転自在に装置本体２０に支持されている。   The first shaft member 61 is disposed at the front side end of the apparatus main body 20 so that the first axis direction is parallel to the paper transport direction X, and is supported by the apparatus main body 20 so as to be rotatable about the first axis direction. ing.

第２軸部材６２は、第２軸方向が奥行き方向Ｙに平行になるように装置本体２０の用紙搬送方向の上流側端部に配置され、第２軸方向を中心に回転自在に装置本体２０に支持されている。   The second shaft member 62 is arranged at the upstream end of the apparatus main body 20 in the sheet conveyance direction so that the second axis direction is parallel to the depth direction Y, and is rotatable about the second axis direction. It is supported by.

伝達部材５０は、長手方向の中心部を第１軸部材６１に固定され、長手方向の上端部に操作ボタン５１を有している。操作ボタン５１は、第１軸部材６１よりも正面側に配置されている。伝達部材５０の長手方向の下端部５２の背面側には、弾性部材の一例であるスプリング５３が配置されている。スプリング５３は、下端部５２を正面側へ付勢している。また、下端部５２の正面側にストッパ５４が配置され、下端部５２の正面側への変位を所定位置で規制している。   The transmission member 50 has a central portion in the longitudinal direction fixed to the first shaft member 61 and has an operation button 51 at the upper end in the longitudinal direction. The operation button 51 is disposed on the front side of the first shaft member 61. A spring 53, which is an example of an elastic member, is disposed on the back side of the lower end portion 52 in the longitudinal direction of the transmission member 50. The spring 53 urges the lower end 52 to the front side. Moreover, the stopper 54 is arrange | positioned at the front side of the lower end part 52, and the displacement to the front side of the lower end part 52 is controlled in the predetermined position.

これによって、操作ボタン５１は、ユーザによって操作されていない状態では基準位置に配置される。また、ユーザによって操作ボタン５１がスプリング５３の弾性力に抗して下方へ押し込まれるのに伴って、下端部５２がストッパ５４に当たるまでの間、操作ボタン５１を押し込む力が第１軸部材６１へ伝達され、第１軸部材６１が第１周方向Ａ即ち正面側へ回転する。操作ボタン５１を押し込む力が解除されると、操作ボタン５１は、スプリング５３の弾性力によって基準位置へ戻される。   Accordingly, the operation button 51 is arranged at the reference position when not operated by the user. Further, as the operation button 51 is pushed downward against the elastic force of the spring 53 by the user, the force pushing the operation button 51 to the first shaft member 61 until the lower end 52 hits the stopper 54. As a result, the first shaft member 61 rotates in the first circumferential direction A, that is, the front side. When the force for pushing the operation button 51 is released, the operation button 51 is returned to the reference position by the elastic force of the spring 53.

操作ボタン５１は、基準位置、少し押し込まれた第１解除位置、さらに押し込まれた第２解除位置に変位自在に構成されている。操作ボタン５１は、基準位置、第１解除位置、第２解除位置へと変位させるときに、各位置で一旦止まりやすいように、各位置での動摩擦力が操作ボタン５１の変位範囲内の他の位置よりも大きくなるように構成されることが好ましい。また、基準位置から第１解除位置までの動摩擦力よりも、第１解除位置から第２解除位置までの動摩擦力の方が大きくなるように構成することもできる。   The operation button 51 is configured to be freely displaceable to a reference position, a first release position that is slightly depressed, and a second release position that is further depressed. When the operation button 51 is displaced to the reference position, the first release position, and the second release position, the dynamic frictional force at each position is different from that within the displacement range of the operation button 51 so that the operation button 51 is easily stopped at each position. It is preferable to be configured to be larger than the position. In addition, the dynamic friction force from the first release position to the second release position can be configured to be larger than the dynamic friction force from the reference position to the first release position.

第１係止部材６５，６６は、第１軸部材６１の両端部に取り付けられている。第１係止部材６６は、第１係止部材６５と実質的に同様に構成されている。第１係止部材６５は、第１基端部６５１及び第１係止部６５２を有している。第１基端部６５１は、第１軸部材６１に固定されている。第１係止部６５２は、第１扉３０の正面側端部即ち開放端部に係止自在なように構成されている。   The first locking members 65 and 66 are attached to both ends of the first shaft member 61. The first locking member 66 is configured in substantially the same manner as the first locking member 65. The first locking member 65 has a first base end portion 651 and a first locking portion 652. The first base end portion 651 is fixed to the first shaft member 61. The 1st latching | locking part 652 is comprised so that it can latch to the front side edge part of the 1st door 30, ie, an open end part.

第１係止部材６５，６６の第１係止部６５２が第１扉３０の開放端部に係止することで、第１扉３０は、装置本体２０の外装部材の一部を構成する位置に保持された閉鎖状態となる。第１軸部材６１が第１周方向Ａに回転することで、第１係止部６５２と第１扉３０の開放端部との係止が解除される。第１係止部６５２と第１扉３０の開放端部との係止が解除されることで、第１扉３０は閉鎖状態から解除されて開放自在にされた解除状態となる。   The position where the first door 30 constitutes a part of the exterior member of the apparatus main body 20 by the first locking portion 652 of the first locking members 65 and 66 being locked to the open end of the first door 30. It will be in the closed state held by. When the first shaft member 61 rotates in the first circumferential direction A, the locking between the first locking portion 652 and the open end of the first door 30 is released. By releasing the engagement between the first locking portion 652 and the open end portion of the first door 30, the first door 30 is released from the closed state and is in a released state that is freely opened.

第２係止部材６７は、第２軸部材６２の両端部に取り付けられている。第２係止部材６７は、第２基端部６７１及び第２係止部６７２を有している。第２基端部６７１は、第２軸部材６２に固定されている。第２係止部６７２は、第２扉４０の用紙搬送方向Ｘの下流側端部即ち開放端部に係止自在なように構成されている。   The second locking member 67 is attached to both ends of the second shaft member 62. The second locking member 67 has a second base end portion 671 and a second locking portion 672. The second base end 671 is fixed to the second shaft member 62. The second locking portion 672 is configured so as to be freely locked to the downstream end of the second door 40 in the paper transport direction X, that is, the open end.

第２係止部材６７の第２係止部６７２が第２扉４０の開放端部に係止することで、第２扉４０は、装置本体２０の外装部材の一部を構成する位置に保持された閉鎖状態となる。第２軸部材６２が第２周方向Ｂ即ち正面視で反時計方向に回転することで、第２係止部６７２と第２扉４０の開放端部との係止が解除される。第２係止部６７２と第２扉４０の開放端部との係止が解除されることで、第２扉４０は閉鎖状態から解除されて開放自在にされた解除状態となる。   When the second locking portion 672 of the second locking member 67 is locked to the open end of the second door 40, the second door 40 is held at a position that constitutes a part of the exterior member of the apparatus main body 20. Closed state. When the second shaft member 62 rotates in the second circumferential direction B, that is, counterclockwise when viewed from the front, the engagement between the second locking portion 672 and the open end of the second door 40 is released. By releasing the locking between the second locking portion 672 and the open end of the second door 40, the second door 40 is released from the closed state and is in a released state in which it can be freely opened.

一対の傾斜カム６３，６４のうち、一方の傾斜カム６３は、第１軸部材６１の用紙搬送方向Ｘの上流側端部に固定され、他方の傾斜カム６４は、第２軸部材６２の正面側端部に固定されている。傾斜カム６３と傾斜カム６４とは、互いに対向するように配置されている。   Of the pair of inclined cams 63, 64, one inclined cam 63 is fixed to the upstream end of the first shaft member 61 in the sheet conveyance direction X, and the other inclined cam 64 is the front of the second shaft member 62. It is fixed to the side edge. The inclined cam 63 and the inclined cam 64 are disposed so as to face each other.

図８に示すように、傾斜カム６３は、用紙搬送方向Ｘの上流側ほど背面側へ傾斜する傾斜面６３１を有している。傾斜カム６４は、傾斜面６３１に平行な傾斜面６４１を有している。傾斜面６３１と傾斜面６４１とは、互いに対向している。   As shown in FIG. 8, the inclined cam 63 has an inclined surface 631 that is inclined toward the back side toward the upstream side in the paper transport direction X. The inclined cam 64 has an inclined surface 641 parallel to the inclined surface 631. The inclined surface 631 and the inclined surface 641 are opposed to each other.

操作ボタン５１が押し込まれて第１軸部材６１が第１周方向Ａに回転すると、傾斜カム６３の傾斜面６３１が傾斜面６４１を押圧することで、第２軸部材６２が第２周方向Ｂに回転する。即ち、操作ボタン５１を操作することで第１軸部材６１が第１周方向Ａに回転し、第１軸部材６１の第１周方向Ａへの回転力は、一対の傾斜カム６３，６４によって、第２軸部材６２の第２周方向Ｂへの回転力に変換され伝達される。   When the operation button 51 is pushed and the first shaft member 61 rotates in the first circumferential direction A, the inclined surface 631 of the inclined cam 63 presses the inclined surface 641, so that the second shaft member 62 moves in the second circumferential direction B. Rotate to. That is, by operating the operation button 51, the first shaft member 61 rotates in the first circumferential direction A, and the rotational force of the first shaft member 61 in the first circumferential direction A is caused by the pair of inclined cams 63 and 64. The second shaft member 62 is converted into a rotational force in the second circumferential direction B and transmitted.

図９に示すように、この第１実施形態では、操作ボタン５１が基準位置にある状態では、一対の傾斜カム６３，６４は互いに所定間隔をあけて離間しており、第１係止部６５２は第１扉３０に係止し、第２係止部６７２は第２扉４０に係止している。これによって、第１扉３０及び第２扉４０は、閉鎖状態に保持される。   As shown in FIG. 9, in the first embodiment, when the operation button 51 is in the reference position, the pair of inclined cams 63 and 64 are spaced apart from each other by a predetermined distance, and the first locking portion 652. Is locked to the first door 30, and the second locking portion 672 is locked to the second door 40. As a result, the first door 30 and the second door 40 are held in a closed state.

操作ボタン５１が基準位置から第１解除位置へ操作されると、これに伴って第１軸部材６１が第１周方向Ａに回転し、第１係止部６５２と第１扉３０との係止は解除され、第１扉３０は解除状態となる。一方、操作ボタン５１が基準位置から第１解除位置へ操作される間の第１軸部材６１の回転によって、傾斜カム６３が傾斜カム６４に近付き接触するが、第２軸部材６２を回転させるまでには至らず、第２係止部６７２と第２扉４０との係止は解除されず、第２扉４０は閉鎖状態に維持される。   When the operation button 51 is operated from the reference position to the first release position, the first shaft member 61 is rotated in the first circumferential direction A accordingly, and the engagement between the first locking portion 652 and the first door 30 is performed. The stop is released, and the first door 30 is released. On the other hand, the rotation of the first shaft member 61 while the operation button 51 is operated from the reference position to the first release position causes the inclined cam 63 to approach and contact the inclined cam 64 until the second shaft member 62 is rotated. Therefore, the engagement between the second locking portion 672 and the second door 40 is not released, and the second door 40 is maintained in the closed state.

操作ボタン５１が第１解除位置から第２解除位置へ操作されると、これに伴って第１軸部材６１はさらに第１周方向Ａに回転し、傾斜カム６３が傾斜カム６４を押圧して第２軸部材６２が第２周方向Ｂに回転し、第２係止部６７２と第２扉４０との係止が解除され、第２扉４０も解除状態となる。なお、勿論、第１扉３０は解除状態のままである。   When the operation button 51 is operated from the first release position to the second release position, the first shaft member 61 further rotates in the first circumferential direction A and the inclined cam 63 presses the inclined cam 64 accordingly. The second shaft member 62 rotates in the second circumferential direction B, the locking between the second locking portion 672 and the second door 40 is released, and the second door 40 is also released. Of course, the first door 30 remains in the released state.

第１扉３０及び第２扉４０は、図示しないスプリングによって開放する方向に付勢されていることが好ましい。これによって、第１扉３０及び第２扉４０のそれぞれは、閉鎖状態から解除状態になったときに、自ら開放する。第１扉３０及び第２扉４０が開放することで、それぞれの設置箇所における用紙詰まりに対するＪＡＭ処理が容易になる。   It is preferable that the 1st door 30 and the 2nd door 40 are urged | biased in the direction opened by the spring which is not shown in figure. Thereby, each of the 1st door 30 and the 2nd door 40 opens itself, when it will be in a cancellation | release state from a closed state. Opening the first door 30 and the second door 40 facilitates JAM processing for paper jams at the respective installation locations.

上述のように構成されることで、それぞれの開閉軸３１，４１が互いに異なる方向に配置された第１扉３０と第２扉４０とは、１個の操作ボタン５１を操作することで、個別に閉鎖状態から解除状態に移行される。即ち、１個の操作ボタン５１を操作することで、第１扉３０のみの解除と、第１扉３０及び第２扉４０の両方の解除とを、ユーザが任意に行うことができる。したがって、第１扉３０及び第２扉４０を閉鎖状態から解除状態にする操作性を向上させることができる。   By being configured as described above, the first door 30 and the second door 40 in which the respective opening and closing shafts 31 and 41 are arranged in different directions are individually operated by operating one operation button 51. From the closed state to the released state. That is, by operating one operation button 51, the user can arbitrarily release only the first door 30 and release both the first door 30 and the second door 40. Therefore, the operativity which makes the 1st door 30 and the 2nd door 40 a cancellation | release state from a closed state can be improved.

また、比較的広い領域に配置された第１扉３０は正面側へ開放し、柱状部１１７に隣接して配置された第２扉４０は柱状部１１７の反対側へ開放するように構成されることで、第１扉３０及び第２扉４０が開放した後のＪＡＭ処理の作業性が向上する。さらに、このように第１扉３０及び第２扉４０の開放後の作業性が良くなる方向に開放するように第１扉３０及び第２扉４０が設置された場合でも、第１扉３０及び第２扉４０を１個の操作ボタン５１で個別に閉鎖状態から解除状態へ移行させることができる。   The first door 30 arranged in a relatively wide area opens to the front side, and the second door 40 arranged adjacent to the columnar part 117 is configured to open to the opposite side of the columnar part 117. Thus, the workability of the JAM processing after the first door 30 and the second door 40 are opened is improved. Further, even when the first door 30 and the second door 40 are installed in such a way that the workability after opening the first door 30 and the second door 40 is improved, the first door 30 and The second door 40 can be individually shifted from the closed state to the released state by one operation button 51.

この第１実施形態では、第１扉３０及び第２扉４０は、用紙搬送方向Ｘの下流側に配置された第１扉３０が第２扉４０よりも先に開放するように構成されている。中継搬送ユニット１０では、第１扉３０を開放すれば、ほとんどの場合は用紙詰まりを解消できるからである。   In the first embodiment, the first door 30 and the second door 40 are configured such that the first door 30 disposed on the downstream side in the paper transport direction X opens before the second door 40. . This is because, in the relay transport unit 10, the paper jam can be resolved in most cases by opening the first door 30.

なお、中継搬送ユニット１０は、第１扉３０及び第２扉４０を開放させる方向に付勢する弾性部材を備えることが好ましい。これによって、第１扉３０及び第２扉４０のそれぞれは、解除状態にされると、弾性部材の弾性力によって自動的に開放するので、より作業性が良くなる。   In addition, it is preferable that the relay conveyance unit 10 is provided with the elastic member urged | biased in the direction which opens the 1st door 30 and the 2nd door 40. As shown in FIG. Thereby, since each of the 1st door 30 and the 2nd door 40 will be automatically open | released by the elastic force of an elastic member, if it will be in a cancellation | release state, workability | operativity will become better.

［第２実施形態］
つぎに、図１０を参照して、第２実施形態に係る扉解除装置１Ａが適用された中継搬送ユニット１０Ａについて説明する。中継搬送ユニット１０Ａは、以下に記載する特徴以外の点は、中継搬送ユニット１０と実質的に同様に構成される。 [Second Embodiment]
Next, with reference to FIG. 10, a relay conveyance unit 10A to which the door release device 1A according to the second embodiment is applied will be described. The relay conveyance unit 10A is configured substantially in the same manner as the relay conveyance unit 10 except for the features described below.

中継搬送ユニット１０Ａでは、第２係止部材６７Ａの第２係止部６７２が、第１係止部６５２よりも変位方向に長く形成されている。また、一対の傾斜カム６３，６４は、操作ボタン５１が基準位置にある状態で互いに接触している。より詳細には、操作ボタン５１が基準位置にある状態から第２扉４０との係止が解除されるまでの第２係止部６７２Ａの変位長さは、操作ボタン５１が基準位置にある状態から第１扉３０との係止が解除されるまでの第１係止部６５２の変位長さよりも、長い。   In the relay conveyance unit 10 </ b> A, the second locking portion 672 of the second locking member 67 </ b> A is formed longer in the displacement direction than the first locking portion 652. The pair of inclined cams 63 and 64 are in contact with each other with the operation button 51 in the reference position. More specifically, the displacement length of the second locking portion 672A from when the operation button 51 is at the reference position to when the lock with the second door 40 is released is when the operation button 51 is at the reference position. Is longer than the displacement length of the first locking portion 652 until the locking with the first door 30 is released.

操作ボタン５１が基準位置にある状態では、第１係止部６５２は第１扉３０に係止し、第２係止部６７２Ａは第２扉４０に係止している。これによって、第１扉３０及び第２扉４０は、閉鎖状態に保持される。   In a state where the operation button 51 is at the reference position, the first locking portion 652 is locked to the first door 30 and the second locking portion 672A is locked to the second door 40. As a result, the first door 30 and the second door 40 are held in a closed state.

操作ボタン５１が基準位置から第１解除位置へ操作されると、これに伴って第１軸部材６１が第１周方向Ａに回転し、第１係止部６５２と第１扉３０との係止は解除され、第１扉３０は解除状態となる。また、第１軸部材６１の回転に伴って第２軸部材６２も第２周方向Ｂに回転するが、第２係止部６７２Ａが第１係止部６５２よりも変位方向に長いので、第１係止部６５２と第１扉３０との係止が解除された状態であっても第２係止部６７２と第２扉４０との係止は解除されず、第２扉４０は閉鎖状態に維持される。   When the operation button 51 is operated from the reference position to the first release position, the first shaft member 61 is rotated in the first circumferential direction A accordingly, and the engagement between the first locking portion 652 and the first door 30 is performed. The stop is released, and the first door 30 is released. Further, as the first shaft member 61 rotates, the second shaft member 62 also rotates in the second circumferential direction B. However, since the second locking portion 672A is longer than the first locking portion 652 in the displacement direction, Even when the locking between the first locking portion 652 and the first door 30 is released, the locking between the second locking portion 672 and the second door 40 is not released, and the second door 40 is closed. Maintained.

操作ボタン５１が第１解除位置から第２解除位置へ操作されると、これに伴って第１軸部材６１はさらに第１周方向Ａに回転し、第２軸部材６２もさらに第２周方向Ｂに回転する。これによって、第２係止部６７２Ａと第２扉４０との係止も解除され、第２扉４０も解除状態となる。なお、勿論、第１扉３０は解除状態のままである。   When the operation button 51 is operated from the first release position to the second release position, the first shaft member 61 is further rotated in the first circumferential direction A and the second shaft member 62 is further moved in the second circumferential direction. Rotate to B. As a result, the locking between the second locking portion 672A and the second door 40 is also released, and the second door 40 is also released. Of course, the first door 30 remains in the released state.

この第２実施形態では、第１軸部材６１の回転開始タイミングと第２軸部材６２の回転開始タイミングとは同じであるが、第１軸部材６１及び第２軸部材６２の回転開始タイミングから、第１係止部６５２と第１扉３０との係止が解除されるまでの時間よりも、第２係止部６７２Ａと第２扉４０との係止が解除されるまでの時間の方が、長くなる。これによって、操作ボタン５１が押し込まれる過程で、第１扉３０が閉鎖状態から解除状態にされるタイミングから、第２扉４０が閉鎖状態から解除状態にされるタイミングを、遅らせることができる。   In the second embodiment, the rotation start timing of the first shaft member 61 and the rotation start timing of the second shaft member 62 are the same, but from the rotation start timing of the first shaft member 61 and the second shaft member 62, The time until the locking between the second locking portion 672A and the second door 40 is released is longer than the time until the locking between the first locking portion 652 and the first door 30 is released. ,become longer. Thereby, in the process in which the operation button 51 is pushed, the timing at which the second door 40 is changed from the closed state to the released state can be delayed from the timing at which the first door 30 is changed from the closed state to the released state.

［第３実施形態］
つぎに、図１１を参照して、第３実施形態に係る扉解除装置１Ｂが適用された中継搬送ユニット１０Ｂについて説明する。中継搬送ユニット１０Ｂは、以下に記載する特徴以外の点は、中継搬送ユニット１０と実質的に同様に構成される。 [Third Embodiment]

The relay transport unit 10B is configured substantially in the same manner as the relay transport unit 10 except for the features described below.

中継搬送ユニット１０Ｂでは、操作ボタン５１Ｂは、伝達部材５０Ｂとは別体に構成され、外装部材に支持されつつ略水平面上をスライド移動するように構成されている。   In the relay conveyance unit 10B, the operation button 51B is configured separately from the transmission member 50B, and is configured to slide and move on a substantially horizontal plane while being supported by the exterior member.

伝達部材５０Ｂは、長手方向の中心部を第１軸部材６１に固定され、長手方向の上端部に作用部５３Ｂを有している。作用部５３Ｂは、第１軸部材６１よりも正面側に配置されている。   The transmission member 50B has a central portion in the longitudinal direction fixed to the first shaft member 61, and has an action portion 53B at the upper end portion in the longitudinal direction. The action part 53 </ b> B is disposed on the front side of the first shaft member 61.

作用部５３Ｂの上面は、少なくとも３段階に高さが異なるように形成されている。一例として、作用部５３Ｂの上面は、用紙搬送方向Ｘの上流側ほど段階的に高くなるように形成されている。このため、操作ボタン５１Ｂが、変位可能範囲内における用紙搬送方向Ｘの下流側端部即ち基準位置に配置されると、操作ボタン５１Ｂが作用部５３Ｂの最も低い面に当接し、第１軸部材６１は回転しない。操作ボタン５１Ｂが少し用紙搬送方向Ｘの上流側の位置即ち第１解除位置へ操作されると、操作ボタン５１Ｂが作用面５３Ｂの中段面に当たることで、操作ボタン５１Ｂが作用部５３Ｂを少し下方へ押し、第１軸部材６１が少し回転する。操作ボタン５１Ｂが変位可能範囲内における用紙搬送方向Ｘの上流側端部即ち第２解除位置に配置されると、操作ボタン５１Ｂが作用部５３Ｂの最も高い面に当たることで、操作ボタン５１Ｂが作用部５３Ｂをさらに押し、第１軸部材６１がさらに回転する。中段面と最も高い面との間は、操作ボタン５１Ｂを操作しやすいように、傾斜面で繋がれている。   The upper surface of the action part 53B is formed so that the height differs in at least three stages. As an example, the upper surface of the action portion 53B is formed so as to increase stepwise toward the upstream side in the paper transport direction X. For this reason, when the operation button 51B is arranged at the downstream end in the paper transport direction X within the displaceable range, that is, at the reference position, the operation button 51B comes into contact with the lowest surface of the action portion 53B, and the first shaft member 61 does not rotate. When the operation button 51B is slightly moved to the upstream position in the sheet transport direction X, that is, the first release position, the operation button 51B hits the middle surface of the action surface 53B, so that the operation button 51B moves the action portion 53B slightly downward. The first shaft member 61 is slightly rotated. When the operation button 51B is disposed at the upstream end in the sheet transport direction X within the displaceable range, that is, at the second release position, the operation button 51B hits the highest surface of the action portion 53B, so that the operation button 51B becomes the action portion. 53B is further pushed, and the first shaft member 61 further rotates. The middle surface and the highest surface are connected by an inclined surface so that the operation button 51B can be easily operated.

この構成においても、１個の操作ボタン５１Ｂを一方向に操作することで、２個の扉３０，４０を個別に閉鎖状態から解除状態へ移行させることができ、操作性がよい。   Also in this configuration, by operating one operation button 51B in one direction, the two doors 30 and 40 can be individually shifted from the closed state to the released state, and the operability is good.

なお、第１係止部材６５と第１扉３０との係止構造は、図９に示すように第１扉３０の孔部に第１係止部６５２が引っ掛かる構造に限定されず、図１２（Ａ）及び図１２（Ｂ）に示すように、第１係止部材６５の凹部６５３に、第１扉３０の突起部３２が引っ掛かるように構成することもできる。第１係止部材６６、第２係止部材６７についても同様である。   The locking structure between the first locking member 65 and the first door 30 is not limited to the structure in which the first locking portion 652 is caught in the hole of the first door 30 as shown in FIG. As shown in FIG. 12A and FIG. 12B, the protrusion 32 of the first door 30 can be configured to be caught in the recess 653 of the first locking member 65. The same applies to the first locking member 66 and the second locking member 67.
