Abstract:
(EN) This drum unit includes a photoreceptor drum and a coupling member. The coupling member has an engaging member, and the engaging member has a driving force receiving part configured to enter a recess in a driving shaft, thereby receiving the drive force for rotating the photoreceptor drum. The coupling member includes a holding member configured to hold the engaging member slidably at least in a radial direction of the drum unit, and a biasing member configured to bias the engaging member.
(FR) Cette invention concerne une unité de tambour comprenant un tambour de photorécepteur et un élément d'accouplement. L'élément d'accouplement comprend un élément de mise en prise, et l'élément de mise en prise comprend une partie de réception de force d'entraînement configurée pour pénétrer dans un évidement dans un arbre d'entraînement, de façon à recevoir la force d'entraînement nécessaire à entraîner en rotation le tambour de photorécepteur. L'élément d'accouplement comprend un élément de retenue configuré pour retenir l'élément de mise en prise de manière coulissante au moins dans une direction radiale de l'unité de tambour, et un élément de sollicitation configuré pour solliciter l'élément de mise en prise.
(JA) ドラムユニットは、感光体ドラムと、カップリング部材を有する。カップリング部材は係合部材を有し、係合部材は駆動軸の凹部へ進入することで感光体ドラムを回転させるための駆動力を受けるように構成された駆動力受け部を有する。また、カップリング部材は、係合部材を少なくともドラムユニットの径方向にスライド可能に保持するように構成された保持部材と、係合部材を付勢するように構成された付勢部材とを有する。
