Title:
COUNTING ASSEMBLY AND DEVELOPING CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2023/056919
Kind Code:
A1
Abstract:
A counting assembly (5,E5) and a developing cartridge (C) having said counting assembly (5,E5). The counting assembly (5,E5) is provided at the longitudinal tail end of the developing cartridge (C), and a rotating member (2,E2) that extends along a first direction is rotatably mounted in a casing (1,E1) of the developing cartridge (C). The developing cartridge (C) is detachably mounted in an imaging device that is provided with a detection part (9). The counting assembly (5,E5) comprises a toggle member (51) and a driven body (52,E51) that are combined with one another. During a counting process of the counting assembly (5,E5), the driven body (52, E51) is driven to rotate around a rotation axis (L5) parallel to the first direction, and the toggle member (51) interacts with the detection part (9). The plane in which a motion track of the driven body (52, E51) is located is perpendicular to the first direction. A toggle protrusion (51b), in the toggle member (51), used to interact with the detection part (9) is configured as at least one movable member (E52) that may move in a direction intersecting with the rotation axis (L5). The driven body (52, E51) does not need to perform an extending and retracting movement relative to the casing (1,E1) along the rotation axis (L5) thereof. Thus, the structures of the counting assembly (5,E5) and the casing (1,E1) may be simplified. Correspondingly, the mounting of the counting assembly (5,E5) and the assembly of the developing cartridge (C) become simple.
