FIG. 11 is a schematic explanatory view of a method of integrally forming the power feeding member, FIG. 11A is an explanatory view when the frame is attached to the first mold, and FIG. 11B is a view illustrating the second mold from the state of FIG. 11A.

In Example 1, when the charging power supply member 61 is integrally formed on the frame body 41 by two-color molding, first, the frame body 41 with the peeling holes 48a and 49a formed by a conventionally known molding method is used. Mold.

次に、図11A、図11Bにおいて、成形された剥離孔48a,49a付の枠体41を第1金型71に装着する。図11Bにおいて、このとき、第1金型71と枠体41との間には、給電部材61に対応する給電部材形成空間71aが形成される。
次に、図11B、図11Cにおいて、第1金型71と対向する第2金型72で、枠体41を挟み込む。このとき、第2金型72には、樹脂射出用の射出口72aが形成されており、前記射出口72aは、枠体41の剥離孔48aに嵌った状態となるように設定されている。

図12は給電部材を剥離する際のたわみの説明図であり、図12Aは最大たわみの説明図、図12Bは撓んでいない状態に対するズレの大きさの説明図である。
実施例1の可視像形成装置UKにおいて、使用終了や故障等で回収された可視像形成装置UKを再利用、いわゆる、リサイクルする場合、枠体41とは材料の異なる給電部材61を枠体41から剥離することで効率的なリサイクルが可能となる。図10B、図12において、実施例1の給電部材61は、前記剥離孔48a,49aから棒状の治具76を挿入して押すことで、給電部材61を容易に剥離することができる。このとき、図12Aに示すように、給電部材61の変形量、すなわち、たわみは、中央集中荷重を受ける両端支持はりと、同等とみなすことができる(近似できる)。したがって、治具76による荷重をWとし、縦弾性係数(ヤング率)をEとし、給電部材の長さ(X軸方向の長さ)をL、給電部材の幅(Z軸方向の幅)をbとし、断面二次モーメントをI(=bh/12)とし、長さLに沿った方向(X軸方向)の変位をx、治具76に押される方向(Y軸方向)の変位(たわみ)をyとした場合に、中央集中荷重を受ける両端支持はりにおけるたわみの式より、以下の式(1)が得られる。
y=−W・x/(12・E・I)+W・L・x/(16・E・I) …式(1)
この式から、中央部(x=L/2の位置)で発生する最大のたわみymaxは、式(2)で表現される。
max=W・L/(48・E・I) …式(2)
(Description of peeling method)
FIG. 12 is an explanatory diagram of the deflection when the power supply member is peeled, FIG. 12A is an explanatory diagram of the maximum deflection, and FIG. 12B is an explanatory diagram of the magnitude of the deviation with respect to the unbent state.
In the visible image forming apparatus UK according to the first embodiment, when the visible image forming apparatus UK collected due to the end of use or failure is reused, that is, when it is recycled, the power feeding member 61 made of a material different from that of the frame body 41 is framed. By separating from the body 41, efficient recycling becomes possible. 10B and 12, the power supply member 61 of the first embodiment can easily peel the power supply member 61 by inserting and pushing the rod-shaped jig 76 from the peeling holes 48a and 49a. At this time, as shown in FIG. 12A, the deformation amount of the power supply member 61, that is, the deflection, can be regarded as equivalent (can be approximated) to the both-end support beam that receives the central concentrated load. Therefore, the load by the jig 76 is W, the longitudinal elastic modulus (Young's modulus) is E, the length of the power supply member (length in the X-axis direction) is L, and the width of the power supply member (width in the Z-axis direction) is and is b, second moment and I (= bh 3/12) , the displacement direction of the (Y axis direction) is pushed the displacement direction (X axis direction) along the length L x, the jig 76 ( When the deflection is y, the following equation (1) is obtained from the equation of deflection in the both-end support beam that receives the central concentrated load.
y = −W · x 3 / (12 · E · I) + W · L 2 · x / (16 · E · I) (1)
From this equation, the maximum deflection y max occurring at the center (the position of x = L / 2) is expressed by equation (2).
y max = W · L 3 / (48 · E · I) (2)

ここで、図12Bにおいて、給電部材61を撓ませた場合に、撓んでいない状態に対する両端部の位置のX軸方向のズレ(長さ)をΔLとし、たわみの中心に対するなす角をθ、たわみの中心から中立面までの半径をrとした場合に、以下の式(3)〜式(5)が得られる。
r・θ=L …式(3)
(r+h/2)・cos(θ/2)=(r−ymax+h/2) …式(4)
ΔL=L/2−(r−ymax+h/2)tan(θ/2) …式(5)
式(3)、式(4)からrを消去して整理すると、式(6)が得られる。
max=(L/θ+h/2){1−cos(θ/2)} …式(6)
また、式(5)において、θを微小として、tan(θ/2)=θ/2と近似し、式(3)を適用して整理すると、式(7)が得られる。
ΔL=(θ/2)・(ymax−h/2) …式(7)
したがって、ΔLが給電部材脱落防止部50の長さになると給電部材61が枠体41から取り外せるので、式(2)、式(6)から、荷重Wを、ある程度の衝撃でも外れず、且つ人が治具76を使用した場合に簡単に外れるような荷重とした場合のθを導出でき、導出されたθと式(7)から、ΔLを導出できる。この結果、荷重Wがある程度の衝撃でも外れず、且つ人が治具76を使用した場合に簡単に外れるように、脱落防止用の爪の長さΔLを設定することができる。
Here, in FIG. 12B, when the power feeding member 61 is bent, the deviation (length) in the X-axis direction between the positions of both ends with respect to the unbent state is ΔL, and the angle formed with respect to the center of the deflection is θ. When the radius from the center to the neutral plane is r, the following equations (3) to (5) are obtained.
r · θ = L (3)
(R + h / 2) · cos (θ / 2) = (r−y max + h / 2) Equation (4)
ΔL = L / 2− (ry max + h / 2) tan (θ / 2) Equation (5)
When r is deleted from the equations (3) and (4) and rearranged, the equation (6) is obtained.
y max = (L / θ + h / 2) {1-cos (θ / 2)} (6)
Further, in equation (5), θ is minute, approximated as tan (θ / 2) = θ / 2, and arranged by applying equation (3), equation (7) is obtained.
ΔL = (θ / 2) · (y max −h / 2) (7)
Therefore, when ΔL becomes the length of the power supply member drop prevention portion 50, the power supply member 61 can be removed from the frame body 41. Therefore, the load W cannot be removed even by a certain degree of impact from the formulas (2) and (6). Can be derived when the load is easily removed when the jig 76 is used, and ΔL can be derived from the derived θ and Equation (7). As a result, the claw length ΔL for preventing the drop can be set so that the load W does not come off even with a certain degree of impact and can be easily removed when a person uses the jig 76.

(実施例1の作用)
前記構成を備えた実施例1の画像形成装置Uでは、給電部材61が枠体41に二色成形により一体的に形成されており、前記従来技術に比べて、給電部材61をプレスしたり、折り曲げたり、湾曲させたり、枠体に取付けるための取付け部や穴等を形成する加工をする必要が無くなる。すなわち、加工や加工後の取付け作業が省略され、コストが低減され、取付け誤差等の発生も低減できる。
また、実施例1の画像形成装置Uでは、リサイクル等で、給電部材61を枠体41から取り外す場合、剥離孔48a,49aに治具76を挿入することで、給電部材61が枠体41から少ない力で容易に取り外される。また、実施例1では、前記給電部材脱落防止部50により、通常の使用状態では、二色成形されて固定されて剥がれにくい給電部材61が仮に剥がれても脱落することが防止される。さらに、実施例1の画像形成装置Uでは、給電部材61を二色成形する際に、剥離孔48aを通じて樹脂が射出されて成形され、剥離孔48aが確実に形成される。また、前記剥離孔48aの形成により環境に対する配慮を視覚的に訴えられる。
(Operation of Example 1)
In the image forming apparatus U according to the first embodiment having the above-described configuration, the power supply member 61 is integrally formed on the frame body 41 by two-color molding. There is no need to bend, curve, or form a mounting portion or hole for mounting on the frame. That is, machining and post-machining attachment work are omitted, costs are reduced, and attachment errors and the like can be reduced.
In the image forming apparatus U according to the first embodiment, when the power supply member 61 is removed from the frame body 41 by recycling or the like, the power supply member 61 is removed from the frame body 41 by inserting a jig 76 into the peeling holes 48a and 49a. It can be easily removed with little force. In the first embodiment, the power supply member drop prevention unit 50 prevents the power supply member 61 that is molded and fixed in two colors and is not easily peeled off even if the power supply member 61 is peeled off in a normal use state. Furthermore, in the image forming apparatus U according to the first embodiment, when the power feeding member 61 is two-color molded, the resin is injected and molded through the peeling hole 48a, so that the peeling hole 48a is reliably formed. Further, due to the formation of the peeling hole 48a, environmental consideration can be visually appealed.

図13において、従来の可視像形成装置01では、枠体02に取付けられた板金等で構成された給電部材03は、被取付け部03aと、被取付け部03aに形成された一対のカシメ部03bとを有し、図14Aに示すように、カシメ部03bが枠体02に形成された突起02aにカシメられることで、給電部材03が枠体02に取付けられていた。
これに対して、図9に示すように、実施例1の可視像形成装置UKでは、枠体41に給電部材61が一体的に形成されている。すなわち、従来技術のように被取付け部03aやカシメ部03bを形成したり、剛性を高めるためのリブを形成するために折り曲げたりする必要が無くなり、被取付け部03aの省略による小型化や、カシメ部03b形成時の廃材の省略による省資源化がされ、さらに、被取付け部03aやカシメ部03bを折り曲げたりして加工する加工作業や廃材処理の省略による低コスト化もされる。
FIG. 13 is an explanatory diagram of an example of a conventional power supply member, and corresponds to FIG. 9 of the first embodiment.
14 is an enlarged explanatory view of the main part of the caulking portion of the conventional power supply member shown in FIG. 13, FIG. 14A is an explanatory view of the attached state, and FIG. 14B is an explanatory view of removing the power supply member.
In FIG. 13, in the conventional visible image forming apparatus 01, the power feeding member 03 composed of a sheet metal attached to the frame body 02 includes an attached portion 03a and a pair of caulking portions formed on the attached portion 03a. 14b, and the crimping portion 03b is crimped to the protrusion 02a formed on the frame body 02, so that the power feeding member 03 is attached to the frame body 02.
On the other hand, as shown in FIG. 9, in the visible image forming apparatus UK according to the first embodiment, a power feeding member 61 is integrally formed on the frame body 41. That is, it is not necessary to form the attachment portion 03a and the crimping portion 03b as in the prior art, or to bend to form a rib for increasing the rigidity. Resource saving is achieved by omitting the waste material at the time of forming the portion 03b, and further, the cost is reduced by omitting the processing operation and the waste material processing for bending the attached portion 03a and the caulking portion 03b.

また、実施例1の給電部材61では、カシメる作業を省略でき、取付けが容易になり、可視像形成装置UKを製造装置により自動的に組み立てることが可能となる。
さらに、リサイクル等で、従来のカシメられた給電部材03を取り外そうとしても、図14Bに示すようにカシメ部03bが引っ掛かり、取外しを妨げる方向の力を作用させる。このため、給電部材03を取り外すためには、矢印に示すようにカシメ部03bをピンセット等の治具で外側に折り曲げる必要があり、取外しに手間がかかり、ピンセット等の治具も必要となり、リサイクルに手間とコストがかかっていた。これに対して、実施例1の給電部材61では、剥離孔48a,49aと治具76で容易に剥離され、速やかにリサイクル作業が実行される。
また、従来のように板金製の給電部材03では、組み付ける際に、手を切ったりして負傷する恐れがあったが、実施例1の給電部材61では、組付け作業時の負傷を防止できる。
Further, in the power supply member 61 according to the first embodiment, the caulking work can be omitted, the attachment becomes easy, and the visible image forming apparatus UK can be automatically assembled by the manufacturing apparatus.
Further, even if the conventional caulking power supply member 03 is removed by recycling or the like, the caulking portion 03b is caught as shown in FIG. 14B, and a force in a direction that prevents the removal is applied. For this reason, in order to remove the power supply member 03, it is necessary to bend the caulking portion 03b outward with a jig such as tweezers as shown by the arrow, and it takes time and effort to remove the jig such as tweezers. It took time and money. On the other hand, in the power supply member 61 of the first embodiment, the peeling holes 48a and 49a and the jig 76 are easily peeled off, and the recycling operation is quickly performed.
In addition, the sheet metal power supply member 03 as in the prior art has a risk of injury when the hand is cut when assembled, but the power supply member 61 of Example 1 can prevent injury during the assembly operation. .
