Printer cartridge with side plates to support an internally accommodated rotating unit

摘要

A printer cartridge including a cartridge casing to accommodate a plurality of rotating units rotating in parallel with each other, the cartridge casing being formed with a support opening on at least one side thereof in the axial direction of the rotating units, and a side plate, at least a part of which is welded to the cartridge casing, to cover the support opening, the side plate including support parts to support axial ends of the rotating units. Since the side plate is not easily disconnected from the cartridge casing, damage of rotating bodies accommodated within the cartridge casing, leakage of the toner, and insertion of foreign matters may be prevented.
