Developer cartridge with counting mechanism

摘要

The invention provides a developer cartridge with a counting mechanism. The developer cartridge comprises a developer and the counting mechanism, wherein the counting mechanism is provided with protrusions which come in contact with a contact lever on an electronic photographing device so as to count the developer cartridge; and each protrusion has a first position and a second position in the direction perpendicular to a side wall of the developer cartridge, and is, in the first position, in contact with the contact lever, but is not, in the second position, in contact with the contact lever. The working principle of the developer cartridge adopting the counting mechanism is greatly different from the prior art. Therefore, the structure of the counting mechanism of the developer cartridge is simpler and more convenient and reliable; the production precision and the production cost are reduced; and the market competitiveness of the developer cartridge is improved.

主权项

1. A developer cartridge with a counting mechanism comprising:
a cartridge body for accommodating a developer, the counting mechanism and a counting mechanism driving member; wherein the counting mechanism comprising a protrusion moving under the driving action of the counting mechanism driving member from a second position in which the protrusion being not in contact with a contact lever on an electronic photographing device to a first position in which the protrusion being in contact with the contact lever on the electronic photographing device so as to count the developer cartridge; and wherein the counting mechanism driving member driving the protrusion to move away from a side wall of the cartridge body in a direction perpendicular to the side wall, the protrusion in the first position is farther away from the side wall than in the second position in the direction perpendicular to the side wall.
