Title (EN) DEVELOPMENT CARTRIDGE
(FR) CARTOUCHE DE DÉVELOPPEMENT
(JA) 現像カートリッジ
Abstract:
(EN) The purpose of the present invention is to prevent a coupling from rotating in a second rotational direction opposite a first rotational direction. A development cartridge 10 comprises: a development roller 12 rotatable about a first axis 12X that extends in an axial direction; a coupling 22 rotatable about a second axis 22X that extends in the axial direction, the coupling 22 serving to rotate the development roller 12; a shaft 27B that supports the coupling 22 rotatably; and a clutch 40 that is rotatable about the shaft 27B together with the coupling 22 when the coupling 22 is rotated in a first rotational direction D1, and that engages with a portion of the shaft 27B when the coupling 22 is rotated in a second rotational direction D2 opposite the first rotational direction D1 so that the clutch 40 and the coupling 22 do not to rotate in the second rotational direction D2.
(FR) Le but de la présente invention est d'empêcher un accouplement de tourner dans une seconde direction de rotation opposée à une première direction de rotation. Une cartouche de développement (10) comprend : un rouleau de développement (12) pouvant tourner autour d'un premier axe (12X) qui s'étend dans une direction axiale ; un accouplement (22) pouvant tourner autour d'un second axe (22X) qui s'étend dans la direction axiale, l'accouplement (22) servant à faire tourner le rouleau de développement (12) ; un arbre (27B) qui supporte l'accouplement (22) de manière rotative ; et un embrayage (40) qui peut tourner autour de l'arbre (27B) conjointement avec l'accouplement (22) lorsque l'accouplement (22) est mis en rotation dans une première direction de rotation (D1) et qui vient en prise avec une partie de l'arbre (27B) lorsque l'accouplement (22) est mis en rotation dans une seconde direction de rotation (D2) opposée à la première direction de rotation (D1) de telle sorte que l'embrayage (40) et l'accouplement (22) ne tournent pas dans la seconde direction de rotation (D2).
(JA) カップリングが第1回転方向とは逆方向の第2回転方向に回転するのを抑えることを目的とする。 現像カートリッジ10は、軸方向に延びる第1軸12Xについて回転可能な現像ローラ12と、軸方向に延びる第2軸22Xについて回転可能なカップリング22であって、現像ローラ12を回転させるためのカップリング22と、カップリング22を回転可能に支持するシャフト27Bと、カップリング22が第1回転方向D1に回転する場合に、カップリング22とともにシャフト27Bについて回転可能なクラッチ40であって、カップリング22が第1回転方向D1と反対の第2回転方向D2に回転する場合には、クラッチ40とシャフト27Bの一部とが係合し、カップリング22とともに第2回転方向D2へ回転しないクラッチ40を備える。
