CA 2675489

An ink cartridge includes a case, an ink supply portion positioned at a front face of the case, a movable member configured to move relative to the case, and at least one resilient member coupled to a rear face of the case and the movable member. The at least one resilient member is configured to expand in an expansion direction and to contract in a contraction direction to move the movable member relative to the case, and a shape of the case in the expansion and contraction directions is unaltered. The entire moveable member is configured to substantially simultaneously move relative to the case when the at least one resilient member expands and contracts.

La cartouche d'encre selon l'invention comprend un carter, une partie de fourniture d'encre positionnée sur une face avant du carter, un élément mobile configuré pour se déplacer par rapport au carter, et au moins un élément élastique couplé à une face arrière du carter et à l'élément mobile. Le ou les éléments élastiques sont configurés pour se dilater dans une direction d'expansion et pour se contracter dans une direction de contraction pour déplacer l'élément mobile par rapport au carter, et une forme du carter dans les directions d'expansion et de contraction n'est pas modifiée. L'élément mobile entier est configuré pour sensiblement simultanément se déplacer par rapport au carter lorsque le ou les éléments élastiques se dilatent et se contractent.
