Description

本発明は、本体開口を開閉するカバー本体と、前記本体開口に対して開閉のために前記カバー本体を回動させる回動軸と、を備えたカバー開閉構造及び画像形成装置に関する。   The present invention relates to a cover opening / closing structure and an image forming apparatus including a cover main body that opens and closes a main body opening, and a rotation shaft that rotates the cover main body to open and close the main body opening.

従来、例えば、画像形成装置等には、常時は閉成状態とされてトナーカートリッジの交換等のメンテナンス時には装置本体側面（又は正面）から傾斜状態で起立されるメンテナンスカバーや、常時は閉成状態とされて利用時には装置本体側面（又は正面）から傾斜状態で起立される手差トレイ等のように、本体開口を開閉するカバー本体を設けたものが周知である。   2. Description of the Related Art Conventionally, for example, in an image forming apparatus or the like, a maintenance cover that is normally closed and stands up from a side surface (or front surface) of the apparatus main body during maintenance such as replacement of a toner cartridge, or is normally closed. It is well known to provide a cover body that opens and closes the body opening, such as a manual feed tray that stands upright from the side surface (or front surface) of the apparatus body when used.

図９乃至図１１は、このような本体開口を開閉するカバー本体を備えたカバー開閉構造を示し、図９は要部の斜視図、図１０は要部の平面図、図１１は要部の拡大断面図である。   9 to 11 show a cover opening / closing structure having a cover body that opens and closes such a body opening. FIG. 9 is a perspective view of the main part, FIG. 10 is a plan view of the main part, and FIG. It is an expanded sectional view.

図において、２１は本体開口２２を開閉するカバー本体、２３は本体開口２２に対する開閉のためにカバー本体２１を回動させる回動軸である。   In the figure, 21 is a cover body that opens and closes the main body opening 22, and 23 is a rotation shaft that rotates the cover main body 21 to open and close the main body opening 22.

この際、本体開口２２は、例えば、回動軸２３の軸線と直交する開口端面２２ａはカバー本体２１のカバー開閉方向（図１１の矢印Ａ参照）と略同方向に形成され、カバー本体２１の開口端面２２ａと対向する周壁面２１ａもカバー本体２１のカバー開閉方向と同方向に形成されている。   At this time, the main body opening 22 is formed, for example, such that an opening end surface 22a orthogonal to the axis of the rotation shaft 23 is formed in substantially the same direction as the cover opening / closing direction of the cover main body 21 (see arrow A in FIG. 11). A peripheral wall surface 21 a facing the opening end surface 22 a is also formed in the same direction as the cover opening / closing direction of the cover body 21.

従って、周壁面２１ａと開口端面２２ａとは、カバー開閉方向と同方向と互いに平行状態で対向しているため、外部から周壁面２１ａと開口端面２２ａとの隙間２４を通して内部が見えて見栄えを損なうばかりでなく、カバー本体２１の左右の隙間２４の幅が異なり易く、この点からも見栄えを損ない易いうえ、カバー本体２１が開口端面２２ａに緩衝し易いという問題が生じていた。   Accordingly, since the peripheral wall surface 21a and the opening end surface 22a face each other in the same direction as the cover opening / closing direction, the inside can be seen from the outside through the gap 24 between the peripheral wall surface 21a and the opening end surface 22a, and the appearance is impaired. In addition, the widths of the left and right gaps 24 of the cover main body 21 are likely to be different. From this point of view, it is easy to impair the appearance, and the cover main body 21 is likely to buffer the opening end surface 22a.

尚、このような見栄えを向上させるため、開口端面２２ａに対するカバー本体２１の中心出しを容易に行うため、カバー本体２１の閉止時にカバー本体２１を本体開口２２にロックするロック機構を設けると共に、このロック機構にカバー本体２１を開口中心方向に付勢するバネを設けたものが知られている（例えば、特許文献１参照）。
特開２００４−３５４８４６号公報 In order to improve the appearance, the center of the cover body 21 with respect to the opening end surface 22a can be easily centered. Therefore, a lock mechanism is provided for locking the cover body 21 to the body opening 22 when the cover body 21 is closed. A lock mechanism provided with a spring that biases the cover main body 21 toward the center of the opening is known (see, for example, Patent Document 1).
JP 2004-354846 A

ところが、上記の如く構成されたカバー開閉構造にあっては、カバー本体２１の中心出しをするためにバネ等を配置しなければならず、カバー本体２１の開閉作業の際に大きな作業力を必要とするうえ、バネ等の付勢部材を配置するための設置スペースを確保しなければならないばかりでなく、組み付け作業コスト並びに部品コストが高騰するといった問題が生じていた。   However, in the cover opening / closing structure configured as described above, a spring or the like must be arranged to center the cover body 21, and a large working force is required when opening and closing the cover body 21. In addition, there is a problem that not only the installation space for arranging the biasing member such as a spring has to be secured, but also the assembling work cost and the part cost are increased.

そこで、本発明は、上記事情を考慮し、特別な部品を用いることなく、カバー本体と本体開口との見栄えを向上し得て、しかも、カバー本体と本体開口との隙間管理を容易に行うことができるカバー開閉構造を提供することを目的とする。   Therefore, in consideration of the above circumstances, the present invention can improve the appearance of the cover main body and the main body opening without using special parts, and can easily manage the gap between the cover main body and the main body opening. An object of the present invention is to provide a cover opening / closing structure that can be used.

本発明のカバー開閉構造は、本体開口を開閉するカバー本体と、前記本体開口に対して開閉のために前記カバー本体を回動させる回動軸と、を備えたカバー開閉構造において、 前記本体開口の少なくとも前記回動軸の軸線と直交する開口端面がその外側端縁よりも内側端縁の方が前記本体開口の開口中心寄りに位置するように傾斜され、前記本体開口を前記カバー本体で閉成している状態のときに前記開口端面と対向する前記カバー本体の周壁面がその外側端縁よりも内側端縁の方が前記本体開口の開口中心寄りに位置するように傾斜されていると共に、前記本体開口を前記カバー本体で閉成している状態のときに前記周壁面の前記外側端縁が前記開口端面の前記外側端縁と前記内側端縁とで形成される傾斜幅内に位置されていることを特徴とする。   The cover opening / closing structure of the present invention is a cover opening / closing structure comprising: a cover body that opens and closes a body opening; and a pivot shaft that rotates the cover body to open and close the body opening. The opening end surface orthogonal to the axis of the pivot shaft is inclined so that the inner end edge is located closer to the opening center of the main body opening than the outer end edge, and the main body opening is closed by the cover main body. In the state where it is formed, the peripheral wall surface of the cover main body facing the opening end surface is inclined so that the inner end edge is located closer to the opening center of the main body opening than the outer end edge. When the body opening is closed by the cover body, the outer edge of the peripheral wall surface is located within an inclined width formed by the outer edge and the inner edge of the opening edge. Specially that To.

この際、前記カバー本体の開閉方向に対する前記開口端面の傾斜角度をα、前記カバー本体の開閉方向に対する前記周壁面の傾斜角度をβとしたときに、α≒βとするのが好ましいが、α＞βとすればカバー本体の中心出しを一層容易とすることができ、α＜βとすれば外部から隙間を通して内部をより一層見難くすることができる。   At this time, when the inclination angle of the opening end surface with respect to the opening / closing direction of the cover body is α and the inclination angle of the peripheral wall surface with respect to the opening / closing direction of the cover body is β, α≈β is preferable, If it is> β, the centering of the cover body can be made easier, and if α <β, the inside can be made more difficult to see through the gap from the outside.

また、本発明は、請求項１乃至請求項４の何れかの構成からなるカバー開閉構造を採用した画像形成装置とすることができる。   In addition, the present invention can provide an image forming apparatus employing a cover opening / closing structure having any one of the first to fourth aspects.

この際、カバー本体としては、装置本体の正面又は側面に本体開口を形成したメンテナンスカバーとしても良いし、手差トレイとしても良い。   At this time, the cover main body may be a maintenance cover in which a main body opening is formed on the front or side of the apparatus main body, or a manual feed tray.

本発明のカバー開閉構造は、特別な部品を用いることなく、カバー本体と本体開口との見栄えを向上し得て、しかも、カバー本体と本体開口との隙間管理を容易に行うことができる。   The cover opening / closing structure of the present invention can improve the appearance of the cover main body and the main body opening without using any special parts, and can easily manage the gap between the cover main body and the main body opening.

次に、本発明の一実施形態に係るカバー開閉構造について、図面を参照して説明する。   Next, a cover opening / closing structure according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view schematically showing a cover opening / closing structure according to an embodiment of the present invention. FIG. 3 is a plan view schematically showing a cover opening / closing structure according to one embodiment of the present invention, FIG. 4 is an enlarged sectional view of a main part of the cover opening / closing structure according to one embodiment of the present invention, and FIG. FIG. 6 is an enlarged cross-sectional view of the main part of Modification 2 of the cover opening / closing structure according to one embodiment of the present invention, and FIG. FIG. 8 is a perspective view of a printer as another image forming apparatus adopting the cover opening / closing structure according to an embodiment of the present invention. It is.

図１に示すように、本発明の一実施形態に係る画像形成装置１は、装置本体２の正面から引き出し可能な給紙カセット３と、給紙カセット３の上方に配置されてトナー交換作業等を行う際に開放されるカバー本体としてのメンテナンスカバー４と、画像形成装置１を複写機・ファクシミリ等として用いる際にその原稿を読み取るための自動原稿送り装置（ＡＤＦ）５と、画像形成装置１の操作を行うための操作パネル部６とを備えている。   As shown in FIG. 1, an image forming apparatus 1 according to an embodiment of the present invention includes a paper feed cassette 3 that can be pulled out from the front of the apparatus main body 2 and a toner replacement operation that is disposed above the paper feed cassette 3. A maintenance cover 4 as a cover body that is opened when the image forming operation is performed, an automatic document feeder (ADF) 5 for reading the original when the image forming apparatus 1 is used as a copying machine or a facsimile, and the image forming apparatus 1. And an operation panel unit 6 for performing the above operations.

メンテナンスカバー４は、図２及び図３に示すように、装置本体２（一部を模式的に図示）に形成された本体開口７を常時は閉成しており、手動にて手前に引くことにより回動軸８を中心として開放方向に回動（図１の太矢印Ｂ参照）することで本体開口７を開放する。   As shown in FIGS. 2 and 3, the maintenance cover 4 always closes the main body opening 7 formed in the apparatus main body 2 (partially shown schematically), and is manually pulled forward. Thus, the main body opening 7 is opened by rotating in the opening direction around the rotation shaft 8 (see the thick arrow B in FIG. 1).

本体開口７の回動軸８の軸線と直交する開口端面７ａは、図４に示すように、その外側端縁７ｂよりも内側端縁７ｃの方が本体開口７の開口中心寄りに位置するように傾斜されている。また、本体開口７をメンテナンスカバー４で閉成している時に開口端面７ａと対向するメンテナンスカバー４の周壁面４ａにおいても、その外側端縁４ｂよりも内側端縁４ｃの方が本体開口７の開口中心寄りに位置するように傾斜されている。   As shown in FIG. 4, the opening end surface 7 a orthogonal to the axis of the rotation shaft 8 of the main body opening 7 is such that the inner end edge 7 c is positioned closer to the opening center of the main body opening 7 than the outer end edge 7 b. It is inclined to. Further, also on the peripheral wall surface 4a of the maintenance cover 4 that faces the opening end surface 7a when the main body opening 7 is closed by the maintenance cover 4, the inner end edge 4c is closer to the main body opening 7 than the outer end edge 4b. It is inclined so as to be located closer to the center of the opening.

この際、メンテナンスカバー４の開閉方向（図４の矢印Ａ参照）に対する開口端面７ａの傾斜角度をα（左右均等）、メンテナンスカバー４の開閉方向に対する周壁面４ａの傾斜角度をβ（左右均等）としたときに、α≒βに設定することにより、メンテナンスカバー４を組み付ける際やメンテナンスカバー４を開放状態から閉成状態とする際、周壁面４ａが開口端面７ａに案内され、本体開口７に対するメンテナンスカバー４の中心出しを容易に行うことができる。また、メンテナンスカバー４を開放状態から閉成状態とするときには、メンテナンスカバー４を本体開口７の奥側まで押し入れることで中心出しを容易に行うことができ、この状態から操作力を開放（手を離す）すれば、メンテナンスカバー４が開放方向に戻されつつ本体開口７とメンテナンスカバー４（開口端面７ａと周壁面４ａ）との隙間９をメンテナンスカバー４の左右で均一とすることができる。   At this time, the inclination angle of the opening end surface 7a with respect to the opening / closing direction of the maintenance cover 4 (see arrow A in FIG. 4) is α (equal to the left and right), and the inclination angle of the peripheral wall surface 4a with respect to the opening / closing direction of the maintenance cover 4 is β (equal to the left and right). When the maintenance cover 4 is assembled or the maintenance cover 4 is changed from the open state to the closed state by setting α≈β, the peripheral wall surface 4a is guided to the opening end surface 7a and The centering of the maintenance cover 4 can be easily performed. Further, when the maintenance cover 4 is changed from the open state to the closed state, the maintenance cover 4 can be easily centered by pushing the maintenance cover 4 to the back side of the main body opening 7, and the operating force is released from this state. , The clearance 9 between the main body opening 7 and the maintenance cover 4 (opening end surface 7a and peripheral wall surface 4a) can be made uniform on the left and right sides of the maintenance cover 4 while the maintenance cover 4 is returned in the opening direction.

尚、本実施の形態においては、隙間９の幅は２ｍｍ、本体開口７の奥行き寸法は２０ｍｍ、α，βの各角度は５．７°以上である。   In the present embodiment, the width of the gap 9 is 2 mm, the depth dimension of the main body opening 7 is 20 mm, and the angles α and β are 5.7 ° or more.

また、開口端面７ａの外側端縁７ｂと内側端縁７ｃ並びに周壁面４ａの外側端縁４ｂと内側端縁４ｃは、カバー閉成状態において、メンテナンスカバー４の開閉方向と直交する外側端縁７ｂと内側端縁７ｃとの傾斜幅Ｗの範囲内に外側端縁４ｂが位置することにより、実質的に外側端縁４ｂが開口端面７ａに正面方向でオーバーラップされることとなり、画像形成装置１の正面方向から隙間９を見た際、この隙間９が暗くない（影が無い）ように視認される。   Further, the outer edge 7b and the inner edge 7c of the opening end surface 7a and the outer edge 4b and the inner edge 4c of the peripheral wall surface 4a are the outer edge 7b orthogonal to the opening / closing direction of the maintenance cover 4 in the cover closed state. When the outer edge 4b is positioned within the range of the inclination width W between the inner edge 7c and the inner edge 7c, the outer edge 4b is substantially overlapped with the opening end surface 7a in the front direction. When the gap 9 is viewed from the front direction, the gap 9 is visually recognized as not dark (no shadow).

尚、周壁面４ａの内側端縁４ｃにおいても、カバー閉成状態の際には、傾斜幅Ｗの範囲内に位置しているのがより好ましい。   In addition, it is more preferable that the inner edge 4c of the peripheral wall surface 4a is located within the range of the inclined width W when the cover is closed.

ところで、傾斜角度αと傾斜角度βとは、例えば、図５に示すように、α＞βとすればメンテナンスカバー４の中心出しを一層容易とすることができ、図６に示すように、α＜βとすれば外部から隙間９を通して内部をより一層見難くすることができる。   Incidentally, the inclination angle α and the inclination angle β are, for example, as shown in FIG. 5, if α> β, the centering of the maintenance cover 4 can be further facilitated, and as shown in FIG. If <β, the inside can be made more difficult to see through the gap 9 from the outside.

さらに、メンテナンスカバー４の周壁面４ａは、その樹脂成形時（射出成形等）の際の成形金型の抜きを、スライドコア等を用いることなく離型させるために、奥行き方向に薄肉となるような肉厚構造が採用されているが、その厚肉部分でのヒケ等の発生を防止するため、図７に示すように、肉抜き部４ｄを形成しても良い。   Further, the peripheral wall surface 4a of the maintenance cover 4 is made thin in the depth direction in order to release the molding die during resin molding (such as injection molding) without using a slide core or the like. Although a thick wall structure is employed, as shown in FIG. 7, a thinned portion 4d may be formed in order to prevent the occurrence of sink marks or the like in the thick wall portion.

また、上記実施の形態では、画像形成装置１を複合機に適用し、そのメンテナンスカバー４をカバー本体として説明したが、例えば、図８に示すように、画像形成装置１１としてのプリンタ専用機に適用し、その装置本体１２の正面から引き出し可能な給紙カセット１３とは別に転写紙を供給することができる手差トレイ１４を本発明のカバー本体とすることも可能である。   In the above embodiment, the image forming apparatus 1 is applied to a multi-function peripheral and the maintenance cover 4 is described as a cover main body. However, for example, as shown in FIG. The manual feed tray 14 capable of supplying transfer paper separately from the paper feed cassette 13 that can be applied and pulled out from the front of the apparatus main body 12 can be used as the cover main body of the present invention.

尚、本発明のカバー開閉構造は、上述した画像形成装置１，１１に限定されるものではなく、回動式（縦開き・横開き・観音開きを問わない）のカバー開閉構造全般に適用することができる。   Note that the cover opening / closing structure of the present invention is not limited to the image forming apparatuses 1 and 11 described above, and is applicable to a general cover opening / closing structure of any type of rotation (regardless of vertical opening, horizontal opening, and double door opening). Can do.
