要約
(EN)
Provided is a process unit which enables simple and easy handling and easy mounting and dismounting of a photosensitive drum. A shaft portion (314) at one end of a photosensitive drum (31A) is fitted in a hole (4011) of one receiving portion (401), and the photosensitive drum is moved from the front of a mounting space into the mounting space (410). The photosensitive drum (31A) is temporarily supported by receiving the repulsive force of a cleaning blade (351) and positioned in a predetermined position of the mounting space (410). A lock member (500) is then withdrawn against biasing by a biasing member (600) in order to cause the lock member (500) to support a shaft portion (315) at the other end of the photosensitive drum (31A). Thereafter, the shaft portion (315) at the other end of the photosensitive drum (31A) is supported by the lock member (500) by the restoring force of the biasing member (600), and the photosensitive drum (31A) is locked in a mounted state.

La présente invention a trait à une unité de traitement qui permet le maniement simple et facile d'un tambour photosensible ainsi que le montage et le démontage faciles de ce tambour photosensible. Une partie tige (314) à une extrémité d'un tambour photosensible (31A) se loge dans un orifice (4011) d'une partie réceptrice (401), et le tambour photosensible se déplace depuis l'avant d'un espace de montage dans l'espace de montage (410). Ledit tambour photosensible (31A) est porté de manière temporaire grâce à la réception de la force de répulsion d'une racle de nettoyage (351) et occupe une position prédéfinie dans l'espace de montage (410). Puis, un élément de blocage (500) se rétracte du fait de la sollicitation exercée par un élément de sollicitation (600) afin que cet élément de blocage (500) puisse porter une partie tige (315) à l'autre extrémité du tambour photosensible (31A). Par la suite, ladite partie tige (315) à l'autre extrémité du tambour photosensible (31A) est portée par l'élément de blocage (500) grâce à la force de rétablissement de l'élément de sollicitation (600), et le tambour photosensible (31A) est bloqué à l'état monté.

 感光体ドラムの取り扱いが簡便で、着脱を容易に行えるプロセスユニットを提供する。感光体ドラム(31A)の一端の軸部(314)を一方の受け部(401)の孔(4011)に嵌合させておいて、感光体ドラムを装着空間の前方から装着空間(410)内に移動させる。感光体ドラム(31A)がクリーニングブレード(351)の反発力を受けて仮支持され、装着空間(410)の所定位置に位置決めされる。そして、感光体ドラム(31A)の他端の軸部(315)をロック部材(500)に支持させるべく、ロック部材(500)を付勢部材(600)による付勢に抗して退避させる。その後、付勢部材(600)による復元力で感光体ドラム(31A)の他端の軸部(315)がロック部材(500)に支持され、感光体ドラム(31A)は装着状態にロックされる。
