Description

本考案は電子画像生成装置に関し、詳しくは電子画像生成装置のトナーカートリッジを装着するための連結部材に関するものである。   The present invention relates to an electronic image generation apparatus, and more particularly to a connecting member for mounting a toner cartridge of the electronic image generation apparatus.

一般の電子画像生成装置、例えばコピー機またはプリンターなどは内部に交換可能なトナーカートリッジを有する。
トナーカートリッジはハウジングの内部に感光体ドラムや現像ドラムなどのローラーを有する。ローラーはトナーカートリッジのハウジングの内部に位置するローラー本体と、ローラー本体の一端に配置される連結部材と、連結部材に接続される回転力受け部材とを有する。連結部材はローラー本体に連結されてローラー本体とともに回転する。回転力受け部材はハウジングに突出し、電子画像生成装置内の駆動ヘッドに嵌まり込む。駆動ヘッドが回転すると、ローラー本体は回転力受け部材および連結部材によってハウジングに対して回転し、感光または現像作業を行う。 A general electronic image generation apparatus, such as a copier or a printer, has a replaceable toner cartridge inside.
The toner cartridge has rollers such as a photosensitive drum and a developing drum inside a housing. The roller has a roller main body located inside the housing of the toner cartridge, a connecting member disposed at one end of the roller main body, and a rotational force receiving member connected to the connecting member. The connecting member is connected to the roller body and rotates together with the roller body. The rotational force receiving member protrudes from the housing and fits into a driving head in the electronic image generating apparatus. When the drive head rotates, the roller body rotates with respect to the housing by the rotational force receiving member and the connecting member, and performs a photosensitive or developing operation.

電子画像生成装置にトナーカートリッジの着脱を行うには、自由に旋転できる方式で回転力受け部材と連結部材を組み合わせなければならない。従って、回転力受け部材と連結部材とを組み合わせ、一定範囲内に回転力受け部材を自由に回転させることができる、回転力受け部材を連結部材から逸脱させない方法を探ることはそれに関連する業者が解決したい技術問題である。   In order to attach / detach the toner cartridge to / from the electronic image generating apparatus, the rotational force receiving member and the connecting member must be combined in a manner that allows free rotation. Therefore, it is possible to combine a rotational force receiving member and a connecting member, and to search for a method that allows the rotational force receiving member to freely rotate within a certain range without causing the rotational force receiving member to deviate from the connecting member. The technical problem you want to solve.

これに対する解決案は次の通りである。連結部材を本体およびキャップに分け、回転力受け部材のピンを本体に差し込み、続いて本体にキャップを被せれば、ピンを本体およびキャップの間に安定させ、回転力受け部材を自由に回転させるように連結部材に装着することができる。
しかしながら、連結部材を装着するには本体およびキャップを組み合わせることが必要であるため、構造が複雑で装着にかかる時間がかかるだけでなく、製造コストが削減できない。 The solution to this is as follows. If the connecting member is divided into the main body and the cap, the pin of the rotational force receiving member is inserted into the main body, and then the cap is put on the main body, the pin is stabilized between the main body and the cap, and the rotational force receiving member is freely rotated. Can be attached to the connecting member.
However, since it is necessary to combine the main body and the cap in order to mount the connecting member, the structure is complicated and it takes time to mount, and the manufacturing cost cannot be reduced.

本考案は、回転力受け部材の連結に用い、回転力受け部材を逸脱させず一定範囲内に自由に回転させることができる連結部材を提供することを主な目的とする。   The main object of the present invention is to provide a connecting member that is used for connecting a rotational force receiving member and can be freely rotated within a certain range without departing from the rotational force receiving member.

本考案は、構造の簡単化および製造工程の迅速化を実現させ、回転受け部材の装着にかかる時間を短縮することができる連結部材を提供することをもう一つの目的とする。   Another object of the present invention is to provide a connecting member that can simplify the structure and speed up the manufacturing process and reduce the time required for mounting the rotation receiving member.

上述した課題を解決するための連結部材は、円筒部、底部、開口部、二つの弾性アームおよび二つのピン穴を備える。
円筒部は第一仮想軸線に位置する。底部は円筒部の一端に形成される。開口部は円筒部の別の一端に形成される。二つの弾性アームは相互に間隔を置いて底部から開口部へ伸びて形成され、それぞれ円筒部の内壁と一定距離を保つ。二つのピン穴は二つの弾性アームに別々に形成され、第二仮想軸線に沿って伸びていく。第二仮想軸線は第一仮想軸線に平行ではない。 A connecting member for solving the above-described problem includes a cylindrical portion, a bottom portion, an opening, two elastic arms, and two pin holes.
The cylindrical portion is located on the first virtual axis. The bottom part is formed at one end of the cylindrical part. The opening is formed at another end of the cylindrical portion. The two elastic arms are formed to extend from the bottom part to the opening part at a distance from each other, and maintain a certain distance from the inner wall of the cylindrical part. The two pin holes are separately formed in the two elastic arms and extend along the second imaginary axis. The second virtual axis is not parallel to the first virtual axis.

上述した特徴により、連結部材は回転力接続部との連結に用いられ、かつ回転力受け部材を逸脱させず一定範囲内に自由に回転させることができる。
上述したとおり、本考案は連結部材の構造が簡単であり、製造工程が迅速であるため、回転力受け部材の装着にかかる時間を短縮することができる。 Due to the above-described features, the connecting member is used for connection with the rotational force connecting portion, and can be freely rotated within a certain range without departing from the rotational force receiving member.
As described above, according to the present invention, the structure of the connecting member is simple and the manufacturing process is quick, so that the time required for mounting the rotational force receiving member can be shortened.

以下、本考案による連結部材を図面に基づいて説明する。   Hereinafter, a connecting member according to the present invention will be described with reference to the drawings.

（第１実施形態）
図１に示すように、本考案の第１実施形態による連結部材１０は電子画像生成装置１に装着される。よく見掛けられる電子画像生成装置１はコピー機またはプリンターなどである。
電子画像生成装置１はトナーカートリッジ５および駆動ヘッド４を備える。トナーカートリッジ５は電子画像生成装置１の内部の格納空間２に装着され、内部にローラー６を有する。駆動ヘッド４は電子画像生成装置１の側壁３に装着され、かつ電子画像生成装置１の格納空間２に差し込まれてトナーカートリッジ５の内部のローラー６に嵌まり込む。ローラー６は駆動ヘッド４の駆動力によって回転する。 (First embodiment)
As shown in FIG. 1, the connecting member 10 according to the first embodiment of the present invention is attached to the electronic image generating apparatus 1. A commonly seen electronic image generating apparatus 1 is a copier or a printer.
The electronic image generation apparatus 1 includes a toner cartridge 5 and a drive head 4. The toner cartridge 5 is mounted in the storage space 2 inside the electronic image generating apparatus 1 and has a roller 6 inside. The drive head 4 is mounted on the side wall 3 of the electronic image generation apparatus 1 and is inserted into the storage space 2 of the electronic image generation apparatus 1 so as to fit into the roller 6 inside the toner cartridge 5. The roller 6 is rotated by the driving force of the driving head 4.

図２に示すように、ローラー６はローラー本体７、回転力受け部材８および連結部材１０を有する。
ローラー６は長い円管状を呈する感光体ドラムや現像ドラムや別の機能を有するローラーなどから構成される。連結部材１０はローラー本体７および回転力受け部材８を連結し、所定角度範囲内に回転力受け部材８を自由に回転させることができる。回転力受け部材８は駆動ヘッド４に接続される。駆動ヘッド４が回転する際、ローラー７本体は回転力受け部材８および連結部材１０によって駆動され、感光または現像作業を行う。 As shown in FIG. 2, the roller 6 includes a roller body 7, a rotational force receiving member 8, and a connecting member 10.
The roller 6 is composed of a photosensitive drum, a developing drum, a roller having another function, or the like having a long circular tube shape. The connecting member 10 connects the roller main body 7 and the rotational force receiving member 8 and can freely rotate the rotational force receiving member 8 within a predetermined angle range. The rotational force receiving member 8 is connected to the drive head 4. When the drive head 4 rotates, the roller 7 body is driven by the rotational force receiving member 8 and the connecting member 10 to perform a photosensitive or developing operation.

図３に示すように、本考案の第１実施形態による連結部材１０は円筒部２０、底部３０、開口部３２、二つの弾性アーム４０および二つのピン穴５０を備える。
回転力受け部材８および連結部材１０はピン９によって結合する。 As shown in FIG. 3, the connecting member 10 according to the first embodiment of the present invention includes a cylindrical part 20, a bottom part 30, an opening part 32, two elastic arms 40, and two pin holes 50.
The rotational force receiving member 8 and the connecting member 10 are coupled by a pin 9.

円筒部２０は、第一仮想軸線２２上に位置し、外側に差込部位２４および環状ギア２６を有する。差込部位２４の直径は環状ギア２６の直径より小さい。差込部材２４はローラー本体７に差し込まれることで連結部材１０とローラー本体７とを結合させ、一緒に回転させることができる。
環状ギア２６は電子画像生成装置１の歯車（図中未表示）と噛み合うことによって回転力を別の部材に伝達する。円筒部２０の環状ギア２６は上述に限らず、別の実施形態においては削除されてもよい。 The cylindrical portion 20 is located on the first virtual axis 22 and has an insertion portion 24 and an annular gear 26 on the outside. The diameter of the insertion part 24 is smaller than the diameter of the annular gear 26. By inserting the insertion member 24 into the roller body 7, the connecting member 10 and the roller body 7 can be coupled and rotated together.
The annular gear 26 is engaged with a gear (not shown in the drawing) of the electronic image generating device 1 to transmit a rotational force to another member. The annular gear 26 of the cylindrical portion 20 is not limited to the above, and may be deleted in another embodiment.

図４に示すように、底部３０は円筒部２０の一端（即ち底部側）に形成される。開口部３２は円筒部２０の別の一端（即ち先端側）に形成される。本文において、「一端」は「別の一端」と相対的であり、狭義の「末端部」に限定されない。つまり、底部３０は狭義の概念によって円筒部２０の最も底部側に至らず、広義の概念によって開口部３２に相対する側に位置する。底部３０は第一仮想軸線２２に沿って伸びる内管３１を有する。
図６および図７に示すように、回転力受け部材８の底部は内管３１に格納される。内管３１は必ず必要な部分であるとは限らず、別の実施形態においては削除されてもよい。 As shown in FIG. 4, the bottom portion 30 is formed at one end (that is, the bottom portion side) of the cylindrical portion 20. The opening 32 is formed at another end (that is, the front end side) of the cylindrical portion 20. In the present text, “one end” is relative to “another end” and is not limited to a “terminal portion” in a narrow sense. That is, the bottom 30 is not located on the most bottom side of the cylindrical portion 20 due to a narrow concept, but is positioned on the side facing the opening 32 according to a broad concept. The bottom 30 has an inner tube 31 that extends along the first virtual axis 22.
As shown in FIGS. 6 and 7, the bottom of the rotational force receiving member 8 is stored in the inner tube 31. The inner pipe 31 is not necessarily a necessary part, and may be deleted in another embodiment.

図３および図４に示すように、二つの弾性アーム４０は相互に間隔を置いて底部３０から開口部３２へ伸びて形成され、それぞれ円筒部２０の内壁と所定距離Ｇを保つ。本実施形態において、二つの弾性アーム４０は第一仮想軸線２２に平行であるが、必ず主要な特徴であるとは限らない。
二つのピン穴５０は二つの弾性アーム４０に別々に形成され、第二仮想軸線５２に沿って伸びていく。第二仮想軸線５２は第一仮想軸線２２に垂直である。二つの弾性アーム４０はそれぞれ開口部３２に向かう先端面４２、相対する内側面４４および相互に背を向けた外側面４６を有する。
二つのピン穴５０は先端面４２に繋がらず二つの弾性アーム４０の内側面４４に凹んで形成される。また二つのピン穴５０は二つの弾性アーム４０を貫通せず第一仮想軸線２２に沿う方向の部位が封じられる。二つの弾性アーム４０の先端面４２は内側面４４に近いガイド部外側４７を有する。二つのピン穴５０はそれぞれ開口部３２に近い一側にガイド部内側４８を有する。別の実施形態において、ガイド部外側４７およびガイド部内側４８は削除されてもよい。 As shown in FIGS. 3 and 4, the two elastic arms 40 are formed to extend from the bottom 30 to the opening 32 at a distance from each other, and maintain a predetermined distance G from the inner wall of the cylindrical portion 20. In the present embodiment, the two elastic arms 40 are parallel to the first imaginary axis 22, but are not necessarily main features.
The two pin holes 50 are separately formed in the two elastic arms 40 and extend along the second virtual axis 52. The second virtual axis 52 is perpendicular to the first virtual axis 22. Each of the two elastic arms 40 has a tip surface 42 facing the opening 32, an opposite inner surface 44, and an outer surface 46 facing away from each other.
The two pin holes 50 are not connected to the front end surface 42 and are formed to be recessed in the inner side surfaces 44 of the two elastic arms 40. The two pin holes 50 do not penetrate the two elastic arms 40 and are sealed in the direction along the first imaginary axis 22. The distal end surfaces 42 of the two elastic arms 40 have a guide portion outer side 47 close to the inner side surface 44. Each of the two pin holes 50 has a guide portion inner side 48 on one side close to the opening portion 32. In another embodiment, the guide part outer side 47 and the guide part inner side 48 may be deleted.

組み立て作業を行う際、回転力受け部材８の貫通溝８１にピン９を差し込んで連結部材１０の弾性アーム４０を弾性的に変形させる。
図４に示すように、二つの弾性アーム４０が外力を受けていない場合、二つの弾性アーム４０の自由端（即ち先端部）は相互に間隔Ｄ１を保つ。
図５に示すように、二つの弾性アーム４０が外力に耐える場合、二つの弾性アーム４０は弾性的に変形し、二つの自由端（即ち先端部）の間に間隔Ｄ２を置くため、ピン９の両端を二つのピン穴５０に差し込む利便性をはかることができる。続いてピン９の両端を二つのガイド部外側４７に当接させながら下へ移動させれば、二つの弾性アーム４０の自由端の間の間隔を広げ、二つのピン穴５０にピン９をスムーズに差し込むことができる。外力が解除された場合、復元した二つの弾性アーム４０は二つのガイド部内側４８によってピン９の両端を二つのピン穴５０へ確実に導くことができる。 When performing assembly work, the pin 9 is inserted into the through groove 81 of the rotational force receiving member 8 to elastically deform the elastic arm 40 of the connecting member 10.
As shown in FIG. 4, when the two elastic arms 40 are not receiving external force, the free ends (that is, the tip portions) of the two elastic arms 40 maintain a distance D1 from each other.
As shown in FIG. 5, when the two elastic arms 40 withstand an external force, the two elastic arms 40 are elastically deformed, and a distance D2 is placed between the two free ends (ie, the tip portions). The convenience of inserting both ends into the two pin holes 50 can be achieved. Subsequently, if the both ends of the pin 9 are moved downward while abutting the two guide portions outside 47, the space between the free ends of the two elastic arms 40 is widened, and the pin 9 is smoothly inserted into the two pin holes 50. Can be plugged into. When the external force is released, the restored two elastic arms 40 can reliably guide both ends of the pin 9 to the two pin holes 50 by the two guide portion inner sides 48.

回転力受け部材８および連結部材１０がピン９によって結合した後、ピン９は固定される。このとき回転力受け部材８は直径がピン９よりかなり大きい貫通溝８１を有するため、連結部材１０から逸脱することなく、ピン９に平行または垂直する方向または任意方向、または所定角度範囲内に自由に回転することができる。
図６および図７に示すように、本体とキャップとを結合させてピンを固定する従来の技術に対し、連結部材１０は一体成型された単一部材であるため、製造作業において部材の数が少なく、本体とキャップとを結合させるステップが必要ない。つまり、本考案は連結部材および回転力受け部材の製作および装着にかかる時間を大幅に短縮することができる。 After the rotational force receiving member 8 and the connecting member 10 are coupled by the pin 9, the pin 9 is fixed. At this time, since the rotational force receiving member 8 has a through groove 81 whose diameter is considerably larger than that of the pin 9, the rotational force receiving member 8 can freely move in a direction parallel to or perpendicular to the pin 9 or in an arbitrary direction, or within a predetermined angle range without departing from the connecting member 10. Can be rotated.
As shown in FIG. 6 and FIG. 7, the connecting member 10 is a single member integrally formed with respect to the conventional technique in which the main body and the cap are joined to fix the pin. There are few steps to join the main body and the cap. In other words, the present invention can greatly reduce the time required for manufacturing and mounting the connecting member and the rotational force receiving member.

（第２実施形態）
本考案は上述に限定されず、考案の精神に基づいて連結部材１０の構造を変えることができる。
図８に示したのは本考案の第２実施形態による連結部材６０である。第１実施形態との違いは次のとおりである。第２実施形態において、二つのピン穴６２、即ち左側のピン穴６２ａおよび右側のピン穴６２ｂは二つの弾性アーム６４を貫通する。左側のピン穴６２ａは内側が漏斗状を呈する。右側のピン穴６２ｂは内側が階段状を呈する。二つのピン穴６２、即ち左側のピン穴６２ａおよび右側のピン穴６２ｂは相対する外側の孔径がピン６６の直径より小さいため、ピン６６は二つのピン穴６２に入り込んで固定されることができる。つまり同様に本考案の目的を達成することができる。 (Second Embodiment)
The present invention is not limited to the above, and the structure of the connecting member 10 can be changed based on the spirit of the invention.
FIG. 8 shows a connecting member 60 according to the second embodiment of the present invention. Differences from the first embodiment are as follows. In the second embodiment, the two pin holes 62, that is, the left pin hole 62 a and the right pin hole 62 b penetrate the two elastic arms 64. The inner side of the left pin hole 62a has a funnel shape. The inner side of the right pin hole 62b is stepped. The two pin holes 62, that is, the left pin hole 62a and the right pin hole 62b have opposite outer diameters smaller than the diameter of the pin 66, so that the pin 66 can enter and be fixed to the two pin holes 62. . That is, the object of the present invention can be achieved similarly.

第１実施形態において、第二仮想軸線５２は第一仮想軸線２２に垂直である。別の実施形態において、第二仮想軸線５２は必ず第一仮想軸線２２に垂直であると限らない。回転力受け部材８の貫通溝８１の形が変われば第二仮想軸線５２が別の方向に沿って伸びてもよい。つまり、第二仮想軸線５２が第一仮想軸線２２に平行でなければよい。   In the first embodiment, the second virtual axis 52 is perpendicular to the first virtual axis 22. In another embodiment, the second virtual axis 52 is not necessarily perpendicular to the first virtual axis 22. If the shape of the through groove 81 of the rotational force receiving member 8 changes, the second virtual axis 52 may extend along another direction. That is, the second virtual axis 52 may not be parallel to the first virtual axis 22.
