本発明の掘り込み式取っ手においては、前記外装の取っ手部の裏面側上部に対向する位置に配設され前記筐体のフレームに固定される補強材を設けるとともに、前記取っ手部の裏面側上部に前記補強材に掛合されるリブを設けたことにより、前記リブが前記補強材に掛合して横方向の荷重を補強材で受けることができる。より具体的には、前記補強材は、前記外装の取っ手部の上部にかかる上方向の荷重を受けるとともに、前記取っ手部のリブとの掛合により前記取っ手部にかかる横方向の荷重を受けることにより、上方向と横方向にかかる荷重をフレーム側の補強材で受けることができ、外装面の破損等の問題を解消することができる。 In the digging type handle of the present invention, a reinforcing material is provided at a position facing the upper part on the back side of the handle part of the exterior and is fixed to the frame of the casing, and on the upper part on the back side of the handle part. By providing the rib to be hooked to the reinforcing material, the rib can be hooked to the reinforcing material and a lateral load can be received by the reinforcing material. More specifically, the reinforcing material receives an upward load applied to the upper portion of the handle portion of the exterior and receives a lateral load applied to the handle portion by engaging with the rib of the handle portion. The load applied in the upward and lateral directions can be received by the reinforcing material on the frame side, and problems such as damage to the exterior surface can be solved.

また、本発明の掘り込み式取っ手においては、前記取っ手部の裏面側上部と前記補強材との間に若干の隙間（０．５ｍｍ〜１．５ｍｍ程度）を設けておき、装置を移動させるときには、前記取っ手部がたわんで該取っ手部の裏面側上部が前記補強材に当接するとともに前記リブが補強材に掛合し、該補強材で前記取っ手部にかかる上方向及び横方向の荷重を受けることにより、取っ手部の裏面側上部と補強材との間に若干の隙間を設けても、上方向と横方向にかかる荷重をフレーム側の補強材で受けることができ、外装面の破損等の問題を解消することができる。なお、このように取っ手部の裏面側上部と補強材との間に若干の隙間を設けておくことにより、取っ手部を設けた外装を筐体に組み付ける際に位置決めの自由度が増し、位置決めしやすくなり、組み付け性が向上する。 In the digging type handle according to the present invention, when a slight gap (about 0.5 mm to 1.5 mm) is provided between the upper portion on the back side of the handle portion and the reinforcing material, and the apparatus is moved. The handle portion bends and the upper part on the back side of the handle portion comes into contact with the reinforcing material and the rib engages with the reinforcing material, and receives the upward and lateral loads applied to the handle portion by the reinforcing material. Therefore, even if a slight gap is provided between the upper part on the back side of the handle part and the reinforcing material, the load applied in the upward and lateral directions can be received by the reinforcing material on the frame side, which causes problems such as damage to the exterior surface. Can be eliminated. In addition, by providing a slight gap between the upper part on the back side of the handle part and the reinforcing material in this way, the degree of freedom in positioning increases when the exterior provided with the handle part is assembled to the housing. This makes it easier to assemble.

本発明の外装部材においては、前記取っ手部の裏面側上部に、前記筐体のフレーム側に固定した補強材と掛合されるリブを有するとともに、前記取っ手部の上方の裏面側に、前記筐体のフレーム側に設けた掛止孔に掛合される位置決め用の引っ掛け突起を有することにより、前記引っ掛け突起を前記筐体のフレーム側に設けた掛止孔に掛合することにより、外装部材の位置決めと仮止めを行うことができ、組み付け性が向上する。
より具体的には、外装部材を筐体に取り付ける際には、前記筐体のフレーム側に固定した補強材に前記取っ手部の裏面側上部のリブを掛合した後、外装面のたわみを利用して前記位置決め用の引っ掛け突起を前記筐体のフレーム側に設けた掛止孔に掛合することにより、外装部材の位置決めと仮止めを行うことができ、組み付け性が向上する。
すなわち、掘り込み式取っ手の取っ手部の裏面側上部に補強材と掛合するリブを設けた場合には、該リブをフレーム側の補強材に掛合する際に、位置決め用の引っ掛け突起をフレーム側の掛止孔に引っ掛ける前に外装部材の取っ手部を補強材の下側に入れるように組み付ける必要があるが、このときに外装のたわみを利用することにより、外装の取っ手部をフレームの補強材の下側に容易に組み付けることができるようになり、取っ手部の組み付けの後、外装部材のたわみを戻すようにして引っ掛け突起を筐体のフレーム側に設けた掛止孔に掛合することにより、外装部材の位置決めと仮止めを容易に行うことができる。 In the exterior member according to the present invention, the upper surface of the handle portion includes a rib that is engaged with a reinforcing member fixed to the frame side of the housing, and the housing is disposed on the back surface above the handle portion. Positioning the exterior member by engaging the hooking protrusion with the hooking hole provided on the frame side of the housing. Temporary fixing can be performed, and assemblability is improved.
More specifically, when the exterior member is attached to the casing, after the rib on the back side of the handle portion is engaged with the reinforcing material fixed to the frame side of the casing, the deflection of the exterior surface is used. By engaging the positioning hooking projection with the latching hole provided on the frame side of the housing, the exterior member can be positioned and temporarily fixed, and the assembling property is improved.
That is, when a rib that engages with the reinforcing material is provided on the upper surface of the back side of the handle portion of the digging type handle, when the rib is engaged with the reinforcing material on the frame side, the hooking protrusion for positioning is arranged on the frame side. It is necessary to assemble the handle of the exterior member so that it is placed under the reinforcement before it is hooked into the retaining hole. At this time, the exterior handle can be attached to the frame reinforcement by using the deflection of the exterior. It can be easily assembled to the lower side, and after assembling the handle part, the exterior projection is engaged with the latching hole provided on the frame side of the housing so as to return the deflection of the exterior member. The member can be easily positioned and temporarily fixed.

なお、本発明の外装部材では、位置決め用の引っ掛け突起をフレーム側の掛止孔に入れる際に、外装部材をたわませた状態で入れるため、掘り込み式取っ手の持ち上げ方向（上方向）に補強材を当接するように設計すると、持ち上げ方向（上方向）の位置決め位置が取っ手部と引っ掛け突起の二箇所となり、位置決めの自由度が無くなり、外装部材の位置決めがしづらいという問題があるが、前述したように、外装部材の取っ手部の裏面側上部と補強材との間に若干の隙間（０．５ｍｍ〜１．５ｍｍ程度）を設けておくことにより、取っ手部を設けた外装部材を筐体に組み付ける際に位置決めの自由度が増し、持ち上げ方向（上方向）の位置決め位置が前記引っ掛け突起側のみになるので、外装部材の位置決めがしやすくなる。
また、このように外装部材の取っ手部の裏面側上部と補強材との間に若干の隙間を設けても、取っ手部に荷重がかかった際に取っ手部がたわんで該取っ手部の裏面側上部が前記補強材に当接するとともに前記リブが補強材に掛合し、該補強材で前記取っ手部にかかる上方向及び横方向の荷重を受けるので、取っ手部の安全性を損なうことがなく、外装面の破損等の問題も解消することができる。 In addition, in the exterior member of the present invention, when placing the hooking protrusion for positioning into the retaining hole on the frame side, the exterior member is inserted in a bent state. If the reinforcing material is designed to abut, the positioning position in the lifting direction (upward) becomes two places, the handle part and the hooking projection, and there is a problem that positioning freedom is lost and positioning of the exterior member is difficult. As described above, by providing a slight gap (about 0.5 mm to 1.5 mm) between the upper portion on the back surface side of the handle portion of the exterior member and the reinforcing material, the exterior member provided with the handle portion is enclosed by the housing. The degree of freedom of positioning increases when assembling to the body, and the positioning position in the lifting direction (upward direction) is only on the hooking projection side, so that the exterior member can be easily positioned.
In addition, even if a slight gap is provided between the upper part of the back surface of the handle part of the exterior member and the reinforcing material in this way, the handle part bends when a load is applied to the handle part, and the upper part of the back side of the handle part. Abuts against the reinforcing material and the rib engages with the reinforcing material and receives the upward and lateral loads on the handle with the reinforcing material, so that the safety of the handle is not impaired. Problems such as damage can be solved.

本発明の筐体においては、外装の少なくとも二箇所に第１乃至第４のいずれか一つの手段の掘り込み式取っ手を有することにより、外装の少なくとも二箇所の取っ手部は持ち上げ方向（上方向）と引張り方向（横方向）の両方の荷重に対して補強がなされているので、取っ手部や外装の破損を防止した構造の筐体を実現することができる。
また、本発明の筐体においては、外装の少なくとも二箇所に第５または第６の手段の外装部材を用いたことにより、掘り込み式の取っ手部を設けた外装部材の位置決めや組み付け性を向上することができる。また、少なくとも二箇所の外装部材の取っ手部は持ち上げ方向（上方向）と引張り方向（横方向）の両方の荷重に対して補強がなされているので、取っ手部や外装部材の破損を防止した構造の筐体を実現することができる。
さらに本発明の画像形成装置においては、筐体として第７または第８の手段の筐体を備えたことにより、運搬や移動がしやすく、運搬や移動時の安全性の高い画像形成装置を実現することができる。 In the housing of the present invention, at least two handle portions of the exterior have the digging type handle of any one of the first to fourth means at at least two locations on the exterior, so that the at least two handle portions of the exterior are in the lifting direction (upward direction). Since the reinforcement is made with respect to both loads in the pulling direction (lateral direction), it is possible to realize a housing having a structure that prevents damage to the handle and the exterior.
Further, in the case of the present invention, the use of the exterior member of the fifth or sixth means in at least two places on the exterior improves the positioning and assembling performance of the exterior member provided with the digging type handle portion. can do. In addition, since the handle parts of at least two exterior members are reinforced against loads in both the lifting direction (upward direction) and the pulling direction (lateral direction), the structure prevents damage to the handle part and the exterior member Can be realized.
Furthermore, in the image forming apparatus of the present invention, by providing the casing of the seventh or eighth means as the casing, an image forming apparatus that is easy to transport and move and has high safety during transportation and movement is realized. can do.

さて、図１に示す画像形成装置１では、画像形成部４と給紙部５が設置される筐体は、例えば図４に示すような骨格構造からなる構造体６と、その構造体の外周を覆う図１に示すような外観の外装１１から構成されている。この筐体の構造体６は、金属製のベースやフレーム、パネル、ブラケット、締結部材（ネジ、ボルト、ナット、等）等で構成されている。また、外装１１は、複数の外装部材（外装カバー、開閉扉等）で構成され、外装カバー等の外装部材は、プラスチックを用いた樹脂一体成型によって形成されている。
なお、図１、図４において、図中の矢印Ａ方向が装置前方（正面側）、矢印Ｂ方向が装置後方（背面側）、矢印Ｃ方向が装置左側方（左側面側）、矢印Ｄ方向が装置右側方（右側面側）である。 In the image forming apparatus 1 shown in FIG. 1, the housing in which the image forming unit 4 and the paper feeding unit 5 are installed includes, for example, a structure 6 having a skeleton structure as shown in FIG. 4 and an outer periphery of the structure. It is comprised from the exterior 11 of the external appearance as shown in FIG. The structural body 6 of the housing is composed of a metal base, frame, panel, bracket, fastening member (screw, bolt, nut, etc.) and the like. The exterior 11 is composed of a plurality of exterior members (exterior cover, open / close door, etc.), and the exterior members such as the exterior cover are formed by resin integral molding using plastic.
1 and 4, the direction of arrow A in the figure is the front of the apparatus (front side), the direction of arrow B is the rear of the apparatus (rear side), the direction of arrow C is the left side of the apparatus (left side), and the direction of arrow D Is the right side (right side).

図１に示す画像形成装置１では、装置の筐体の外装１１の一部に、外装面を装置内側に窪ませた形状の取っ手部１５を有する運搬用の掘り込み式取っ手が設けられている。図１では、掘り込み式取っ手（取っ手部）１５は、外装１１の右側面の後方下部に設けられているが、この他、図示しない左側面の前方下部や後方下部、あるいは装置背面等、少なくとも外装１１の二箇所以上に設けられている。
また、この掘り込み式取っ手の取っ手部１５は、外装１１の一部を構成する外装部材１１ａ（図１の例では、右側面後方の外装カバー）を製造する際に、プラスチックを用いた樹脂一体成型によって外装部材１１ａに形成される。 In the image forming apparatus 1 shown in FIG. 1, a digging handle for transportation having a handle portion 15 having a shape in which an exterior surface is recessed toward the inside of the apparatus is provided in a part of the exterior 11 of the casing of the apparatus. . In FIG. 1, the digging type handle (handle part) 15 is provided at the rear lower part of the right side surface of the exterior 11. It is provided at two or more locations on the exterior 11.
Further, the digging type handle portion 15 is formed of a resin integrated body using plastic when manufacturing an exterior member 11a (in the example of FIG. 1, an exterior cover on the right side rear surface) constituting a part of the exterior 11. The outer member 11a is formed by molding.

この掘り込み式取っ手は、通常、運搬時に手を掛けて装置を持ち上げることを目的として設けられているので、取っ手部１５の裏面側上部には、筐体の骨格を構成する構造体６のフレームに固定した補強材１４が当接して、フレーム側で荷重を受けるようにし、持ち上げ方向（上方向）の補強を行うことがなされている。
ここで、図５は図１に示す画像形成装置１の筐体の掘り込み式取っ手が設けられた部分の断面を装置背面側から見た要部断面図であり、本発明に係る掘り込み式取っ手では、図４及び図５に示すように、外装部材１１ａの取っ手部１５の裏面側上部に対向する位置に断面コの字形の補強材１４を配設し、この補強材１４を筐体の構造体６のフレームに締結部材等で固定している。なお、図６は構造体６の補強材１４が固定された部分を斜め後方から見た要部斜視図、図７は構造体６の補強材１４が固定された部分を右側方から見た要部斜視図である。図５〜７に示す例では、補強材１４の両端側が、構造体６のフレームに締結部材（例えばボルトとナット）で固定されているので、補強材１４が取っ手部１５から受ける上方向の荷重を構造体６のフレームで受けることができる。 Since this digging type handle is normally provided for the purpose of lifting the device by placing a hand during transportation, the frame of the structure 6 constituting the skeleton of the casing is formed on the upper part on the back side of the handle part 15. The reinforcement member 14 fixed to the frame is brought into contact with the frame so as to receive a load on the frame side, and reinforcement in the lifting direction (upward direction) is performed.
Here, FIG. 5 is a cross-sectional view of the main part of the section of the housing of the image forming apparatus 1 shown in FIG. 1 provided with the digging type handle, as viewed from the rear side of the apparatus, and the digging type according to the present invention. In the handle, as shown in FIGS. 4 and 5, a U-shaped reinforcing material 14 is disposed at a position facing the upper part on the back side of the handle portion 15 of the exterior member 11a, and this reinforcing material 14 is attached to the casing. It is fixed to the frame of the structure 6 with a fastening member or the like. 6 is a perspective view of the main part of the structure 6 where the reinforcing member 14 is fixed obliquely viewed from the rear, and FIG. 7 is a main part of the structure 6 where the reinforcing member 14 is fixed viewed from the right side. FIG. In the example shown in FIGS. 5 to 7, since both ends of the reinforcing member 14 are fixed to the frame of the structure 6 with fastening members (for example, bolts and nuts), the upward load that the reinforcing member 14 receives from the handle portion 15. Can be received by the frame of the structure 6.

ところで、画像形成装置１の外装１１の一部に設けられた掘り込み式取っ手は、前述したように運搬時に手を掛けて装置を持ち上げることを目的として設けられているが、装置を移動する際に、ユーザが装置を引きずるようにして移動する場合がある。このような場合に、取っ手部１５に引きずり方向（横方向）の補強がなされていないと、横方向に荷重を受けた場合に、外装面がたわみ、破損するという虞があった。 Incidentally, the digging type handle provided in a part of the exterior 11 of the image forming apparatus 1 is provided for the purpose of lifting the apparatus by placing a hand during transportation as described above. In addition, the user may move by dragging the device. In such a case, if the handle portion 15 is not reinforced in the drag direction (lateral direction), the exterior surface may bend and be damaged when a load is applied in the horizontal direction.

そこで本発明では、図５に示すように、外装部材１１ａの取っ手部１５の裏面側上部１５ａに対向する位置に配設され筐体の構造体６のフレームに固定される補強材１４を設けるとともに、取っ手部１５の裏面側上部１５ａに補強材１４に掛合されるリブ１３を設けている。このように取っ手部１５の裏面側上部１５ａに補強材１４に掛合されるリブ１３を設けることにより、リブ１３が補強材１４に掛合して横方向の荷重を補強材１４で受けることができる。より具体的には、補強材１４は、外装１１の取っ手部１５の上部にかかる上方向の荷重を受けるとともに、取っ手部１５のリブ１３との掛合により取っ手部１５にかかる横方向の荷重を受けることにより、上方向と横方向にかかる荷重を構造体６のフレーム側の補強材１４で受けることができ、外装面の破損等の問題を解消することができる。 Therefore, in the present invention, as shown in FIG. 5, a reinforcing member 14 is provided that is disposed at a position facing the back side upper portion 15a of the handle portion 15 of the exterior member 11a and is fixed to the frame of the structural body 6 of the housing. The rib 13 that is engaged with the reinforcing member 14 is provided on the back side 15a of the handle portion 15. Thus, by providing the rib 13 engaged with the reinforcing material 14 on the back surface side upper portion 15a of the handle portion 15, the rib 13 can be engaged with the reinforcing material 14 and the lateral load can be received by the reinforcing material 14. More specifically, the reinforcing member 14 receives an upward load applied to the upper portion of the handle portion 15 of the exterior 11 and receives a lateral load applied to the handle portion 15 by engaging with the rib 13 of the handle portion 15. As a result, the load applied in the upward and lateral directions can be received by the reinforcing member 14 on the frame side of the structure 6, and problems such as damage to the exterior surface can be solved.

ここで、本発明の掘り込み式取っ手においては、図２に示す概略断面図のように、取っ手部１５の裏面側上部１５ａと補強材１４との間に若干の隙間ｄ、例えば０．５ｍｍ〜１．５ｍｍ程度の隙間ｄを設けておき、装置を移動させるときには、取っ手部１５がたわんで該取っ手部の裏面側上部１５ａが補強材１４の下面に当接するとともにリブ１３が補強材１４に掛合し、該補強材１４で取っ手部１５にかかる上方向及び横方向の荷重を受けるようにしている。これにより、取っ手部１５の裏面側上部１５ａと補強材１４との間に若干の隙間ｄを設けても、上方向と横方向にかかる荷重をフレーム側の補強材１４で受けることができ、外装面の破損等の問題を解消することができる。なお、このように取っ手部１５の裏面側上部１５ａと補強材１４との間に若干の隙間ｄを設けておくことにより、取っ手部１５を設けた外装部材１１ａを筐体に組み付ける際に位置決めの自由度が増し、位置決めしやすくなり、組み付け性が向上する。 Here, in the digging type handle of the present invention, as shown in the schematic cross-sectional view shown in FIG. 2, a slight gap d between the back side upper portion 15 a of the handle portion 15 and the reinforcing material 14, for example, 0.5 mm to When the gap d of about 1.5 mm is provided and the apparatus is moved, the handle portion 15 bends and the back side upper portion 15a of the handle portion comes into contact with the lower surface of the reinforcing member 14 and the rib 13 engages with the reinforcing member 14. The reinforcing material 14 receives the upward and lateral loads on the handle portion 15. As a result, even if a slight gap d is provided between the back side upper portion 15a of the handle portion 15 and the reinforcing member 14, the load applied in the upward and lateral directions can be received by the reinforcing member 14 on the frame side. Problems such as surface breakage can be solved. In addition, by providing a slight gap d between the back side upper portion 15a of the handle portion 15 and the reinforcing member 14 in this way, positioning is performed when the exterior member 11a provided with the handle portion 15 is assembled to the housing. The degree of freedom increases, positioning becomes easier, and assembling improves.

次に図３は、上記掘り込み式取っ手の取っ手部１５が設けられる外装部材１１ａの裏面側の要部斜視図である。図２、図３に示すように、本発明に係る取っ手部１５を有する外装部材１１ａでは、取っ手部１５の裏面側上部１５ａに、筐体のフレーム側に固定した補強材１４と掛合されるリブ１３を設けるとともに、取っ手部１５の上方の裏面側に、図４に示すような筐体のフレーム側に設けた掛止孔１８，１９に掛合される位置決め用の引っ掛け突起１２を設けている。これにより、引っ掛け突起１２を筐体のフレーム側に設けた掛止孔１８，１９に掛合することにより、外装部材１１ａの位置決めと仮止めを行うことができ、組み付け性が向上する。より具体的には、外装部材１１ａを筐体に取り付ける際には、筐体の構造体６のフレーム側に固定した補強材１４に、取っ手部１５の裏面側上部１５ａのリブ１３を掛合した後、外装面のたわみを利用して位置決め用の引っ掛け突起１２を構造体６のフレーム側に設けた掛止孔１８，１９に掛合することにより、外装部材１１ａの位置決めと仮止めを行うことができ、組み付け性が向上する。 Next, FIG. 3 is a perspective view of a main part on the back surface side of the exterior member 11a provided with the handle portion 15 of the digging type handle. As shown in FIGS. 2 and 3, in the exterior member 11 a having the handle portion 15 according to the present invention, a rib that is engaged with the reinforcing member 14 fixed to the frame side of the housing on the back side 15 a of the handle portion 15. 13 and a positioning projection 12 for engaging with retaining holes 18 and 19 provided on the frame side of the housing as shown in FIG. 4 is provided on the back side above the handle portion 15. As a result, by engaging the hooking protrusions 12 with the hooking holes 18 and 19 provided on the frame side of the housing, the exterior member 11a can be positioned and temporarily fixed, and the assembling property is improved. More specifically, when the exterior member 11a is attached to the housing, after the rib 13 of the upper surface 15a on the back surface side of the handle portion 15 is engaged with the reinforcing member 14 fixed to the frame side of the structural body 6 of the housing. The positioning member 11a can be positioned and temporarily fixed by engaging the hooking protrusions 12 and 19 provided on the frame side of the structure 6 with the hooking protrusions 12 for positioning using the deflection of the outer surface. Assembling performance is improved.

さらに詳しく述べると、掘り込み式取っ手の取っ手部１５の裏面側上部１５ａに補強材１４と掛合するリブ１３を設けた場合には、該リブ１３をフレーム側の補強材１４に掛合する際に、位置決め用の引っ掛け突起１２をフレーム側の掛止孔１８，１９に引っ掛ける前に外装部材１１ａの取っ手部１５を補強材の下側に入れるように組み付ける必要があるが、このときに外装部材１１ａのたわみを利用することにより、外装部材１１ａの取っ手部１５をフレームの補強材１４の下側に容易に組み付けることができるようになる。具体的には、外装部材１１ａを筐体の構造体６に組み付ける際には、まず外装部材１１ａの取っ手部１５を補強材１４の下側に入れ、取っ手部１５の裏面側上部１５ａに設けたリブ１３をフレーム側の補強材１４に引っ掛けるようにして組み付けるが、このとき外装部材１１ａの位置決め用の引っ掛け突起１２は構造体６のフレームに当たっているので、外装部材１１ａのたわみを利用して、引っ掛け突起１２の付近がたわみ方向（図２に示す符号１６の矢印の方向）にたわむようにしておけば、リブ１３をフレーム側の補強材１４に容易に掛合することができ、取っ手部１５を容易に組み付けることができる。そして、取っ手部１５の組み付けの後、外装部材１１ａを上方向に持ち上げながら外装部材１１ａのたわみを戻すようにして引っ掛け突起１２と構造体６のフレーム側に設けた掛止孔１８，１９との位置決めを行い、引っ掛け突起１２を掛止孔１８，１９に掛合することにより、外装部材１１ａの位置決めと仮止めを容易に行うことができる。このようにして外装部材１１ａの位置決めと仮止めを行えば、外装部材１１ａは引っ掛け突起１２で構造体６側に仮止めされているので、外装部材１１ａから手を離すことができ、ネジ止め等で外装部材１１ａを構造体６に固定する作業を容易に行うことができる。なお、図８は図４に示す構造体６の補強材１４が固定された部分に、取っ手部１５を有する外装部材１１ａを組み付けた状態を示している。 More specifically, when the rib 13 that engages with the reinforcing member 14 is provided on the back side 15a of the handle portion 15 of the digging type handle, when the rib 13 is engaged with the reinforcing member 14 on the frame side, It is necessary to assemble the handle 15 of the exterior member 11a so that the handle 15 of the exterior member 11a is placed under the reinforcing member before the positioning projection 12 is hooked on the retaining holes 18 and 19 on the frame side. By utilizing the deflection, the handle portion 15 of the exterior member 11a can be easily assembled to the lower side of the reinforcing member 14 of the frame. Specifically, when assembling the exterior member 11 a to the housing structure 6, first, the handle portion 15 of the exterior member 11 a is placed below the reinforcing material 14 and provided on the back side upper portion 15 a of the handle portion 15. The rib 13 is assembled so as to be hooked on the frame-side reinforcing member 14. At this time, the hooking protrusion 12 for positioning the exterior member 11 a is in contact with the frame of the structure 6. If the vicinity of the protrusion 12 is bent in the bending direction (the direction of the arrow 16 shown in FIG. 2), the rib 13 can be easily engaged with the reinforcing member 14 on the frame side, and the handle portion 15 can be easily moved. Can be assembled. Then, after assembling the handle portion 15, the lifting projection 12 and the retaining holes 18, 19 provided on the frame side of the structural body 6 so as to return the deflection of the exterior member 11 a while lifting the exterior member 11 a upward. By positioning and engaging the hooking protrusions 12 with the hooking holes 18 and 19, the exterior member 11a can be easily positioned and temporarily fixed. If the exterior member 11a is positioned and temporarily fixed in this manner, the exterior member 11a is temporarily fixed to the structure 6 side by the hooking projection 12, so that the hand can be released from the exterior member 11a, screwing, etc. Thus, the work of fixing the exterior member 11a to the structure 6 can be easily performed. 8 shows a state in which the exterior member 11a having the handle portion 15 is assembled to the portion of the structure 6 shown in FIG. 4 to which the reinforcing member 14 is fixed.

ところで、図１，２，３，８に示すような形状の外装部材１１ａでは、位置決め用の引っ掛け突起１２をフレーム側の掛止孔１８，１９に入れる際に、外装部材１１ａがたわんだ状態で入れるため、掘り込み式取っ手の持ち上げ方向（上方向）に補強材１４が常に当接しているように設計すると、持ち上げ方向（上方向）の位置決め位置が取っ手部１５の上部と引っ掛け突起１２の二箇所となり、位置決めの自由度が無くなり、外装部材１１ａの位置決めがしづらいという問題がある。そこで前述したように、外装部材１１ａの取っ手部１５の裏面側上部１５ａと補強材１４との間に若干の隙間ｄ（０．５ｍｍ〜１．５ｍｍ程度）を設けるようにしておけば、取っ手部１５を設けた外装部材１１ａを筐体に組み付ける際に、上方向に０．５ｍｍ〜１．５ｍｍ程度の遊びができ、位置決めの自由度が増し、持ち上げ方向（上方向）の位置決め位置が引っ掛け突起１２側のみになるので、外装部材１１ａの位置決めがしやすくなる。
また、このように外装部材１１ａの取っ手部１５の裏面側上部１５ａと補強材１４との間に若干の隙間ｄを設けても、その隙間ｄは０．５ｍｍ〜１．５ｍｍ程度であるので、取っ手部１５に荷重がかかった際に、取っ手部１５が図２の矢印１７で示す向きにたわんで、隙間ｄの０．５ｍｍ〜１．５ｍｍ程度の距離を吸収し、取っ手部１５の裏面側上部１５ａが補強材１４に当接するとともに、リブ１３が補強材１４に掛合し、補強材１４で取っ手部１５にかかる上方向及び横方向の荷重を受けることができる。これにより、装置の運搬や移動時に取っ手部１５の安全性を損なうことがなく、外装面の破損等の問題も解消することができる。 By the way, in the exterior member 11a having the shape as shown in FIGS. 1, 2, 3 and 8, the exterior member 11a is bent when the hooking protrusion 12 for positioning is inserted into the retaining holes 18 and 19 on the frame side. Therefore, if the reinforcing member 14 is designed to always contact in the lifting direction (upward direction) of the digging type handle, the positioning position in the lifting direction (upward direction) is the upper part of the handle portion 15 and the hooking protrusion 12. There is a problem that the degree of freedom of positioning is lost, and positioning of the exterior member 11a is difficult. Therefore, as described above, if a slight gap d (about 0.5 mm to 1.5 mm) is provided between the back surface side upper portion 15a of the handle portion 15 of the exterior member 11a and the reinforcing member 14, the handle portion is obtained. When the exterior member 11a provided with 15 is assembled to the casing, play of about 0.5 mm to 1.5 mm can be performed in the upward direction, the degree of freedom in positioning is increased, and the positioning position in the lifting direction (upward direction) is a hooking projection. Since it becomes only 12 side, it becomes easy to position the exterior member 11a.
Even if a slight gap d is provided between the back surface side upper portion 15a of the handle portion 15 of the exterior member 11a and the reinforcing member 14 in this way, the gap d is about 0.5 mm to 1.5 mm. When a load is applied to the handle portion 15, the handle portion 15 bends in the direction indicated by the arrow 17 in FIG. 2 to absorb a distance of about 0.5 mm to 1.5 mm of the gap d, and the back side of the handle portion 15. The upper portion 15a abuts on the reinforcing member 14, and the rib 13 engages with the reinforcing member 14 so that the reinforcing member 14 can receive the upward and lateral loads applied to the handle portion 15. Thereby, the safety | security of the handle part 15 is not impaired at the time of conveyance and movement of an apparatus, and problems, such as damage of an exterior surface, can also be eliminated.

なお、以上に説明した本発明に係る筐体においては、外装の少なくとも二箇所に上記の掘り込み式取っ手を有する外装部材１１ａを用いることにより、掘り込み式の取っ手部１５を設けた外装部材１１ａの位置決めや組み付け性を向上することができる。また、少なくとも二箇所の外装部材の取っ手部１５は持ち上げ方向（上方向）と引張り方向（横方向）の両方の荷重に対して補強がなされているので、取っ手部１５や外装部材１１ａの破損を防止した構造の筐体を実現することができる。
さらに本発明の画像形成装置１においては、外装の少なくとも二箇所に上記の掘り込み式取っ手を有する筐体を備えたことにより、運搬や移動がしやすく、運搬や移動時の安全性の高い画像形成装置を実現することができる。 In addition, in the housing | casing which concerns on this invention demonstrated above, the exterior member 11a which provided the digging type handle part 15 by using the exterior member 11a which has said digging type handle in at least two places of an exterior. Positioning and assembling can be improved. In addition, since the handle portions 15 of at least two exterior members are reinforced against loads in both the lifting direction (upward direction) and the pulling direction (lateral direction), damage to the handle portion 15 and the exterior member 11a is prevented. A housing having a prevented structure can be realized.
Furthermore, in the image forming apparatus 1 according to the present invention, the housing having the above-described digging type handle is provided in at least two places of the exterior, so that the image can be easily transported and moved, and the image is highly safe during transport and movement. A forming apparatus can be realized.
