The cartridge may also include a detection protrusion provided at a position away from a rotational center of the rotational member. The detection protrusion may include a main body protruding from the rotational member away from the housing and a pivot part configured to pivot relative to the main body. The detection protrusion may be configured to be changeable between an extended state and a collapsed state with respect to the rotational member. |
