Abstract
(EN)
The purpose of the present invention is to disengage a drive gear and a gear other than a rotating gear from each other. A developer cartridge 1, provided with: a casing 11 capable of containing a toner in the interior; a developing roller 12 extending in the axial direction; a developing electrode 20 electrically connected to the developing roller 12; a rack gear 50 that engages with a gear (agitator gear 31), the rack gear 50 having a protrusion (53, 54); and a cam 70 capable of moving from a first position to a second position set further away from the casing 11 than the first position in the axial direction. The cam 70 has: a first cam surface 73A, which comes into contact with the protrusion at the first position; and a second cam surface 76A, which moves while being in contact with the developing electrode 20 when the cam 70 moves from the first position to the second position, and thereby moves the developing electrode 20 away from the cam 70.

Le but de la présente invention est de libérer l'un de l'autre un engrenage d'entraînement et un engrenage autre qu'un engrenage rotatif. L’invention concerne une cartouche de révélateur (1) qui est pourvue : d'un intérieur de boîtier (11) pouvant contenir une encre en poudre ; d'un rouleau de développement (12) s'étendant dans la direction axiale ; d'une électrode de développement (20) connectée au rouleau de développement (12) ; d'un engrenage à crémaillère (50) qui vient en prise avec un engrenage (engrenage d'agitateur 31), l'engrenage à crémaillère (50) ayant une saillie (53, 54) ; d'une came (70) pouvant se déplacer d'une première position à une seconde position située plus loin du boîtier (11) que la première position dans la direction axiale. La came possède : une première surface de came (73A) qui vient en contact avec la saillie au niveau de la première position ; une seconde surface de came (76A) qui se déplace tout en étant en contact avec l'électrode de développement (20) lorsque la came (70) se déplace de la première position à la seconde position, et qui déplace ainsi l'électrode de développement (20) en l’éloignant de la came (70).
