Abstract
A cartridge which may include a housing, a driving input member provided at the housing wherein the driving input member is configured to be rotated by an externally supplied rotation driving force, and a rotational member configured to receive the rotation driving force, which is transmitted from the driving input member, and be rotated thereby. 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.
Claims14
A cartridge comprising:
- a housing;
- a driving input member provided at the housing, the driving input member configured to be rotated by an externally supplied rotation driving force;
- a rotational member configured to receive the rotation driving force, which is transmitted from the driving input member, and be rotated thereby;
- and
- a detection protrusion provided at a position away from a rotational center of the rotational member, the detection protrusion including:
- a main body protruding from the rotational member away from the housing;
- and
- a pivot part configured to pivot relative to the main body,
- wherein the detection protrusion is configured to be changeable between an extended state and a collapsed state with respect to the rotational member, and
- wherein an end portion of the pivot part is located closer to the rotational member when the detection protrusion is in the collapsed state than when the detection protrusion is in the extended state.
A cartridge comprising:
- a housing;
- a driving input member provided in the housing, the driving input member configured to be rotated by an externally supplied rotation driving force;
- a rotational member configured to receive the rotation driving force, transmitted from the driving input member, and be rotated thereby;
- a cover attached to the housing, the cover having an opposite part that faces the rotational member;
- and
- a detection protrusion provided at a position away from a rotational center of the rotational member, the detection protrusion including:
- a main body which protrudes from a face of the rotational member;
- and
- a pivot part configured to pivot relative to the main body in at least a direction orthogonal to a rotational plane in which the rotational member is configured to move,
- wherein the detection protrusion is configured to be changeable between an extended state and a collapsed state;
- and
- wherein, at an initial position, corresponding to a position before the rotational member is rotated, and at a terminal position, corresponding to a position after the rotational member has performed a complete rotation, the opposite part of the cover is configured to contact the detection protrusion and change the detection protrusion from the collapsed state to the extended state,
- wherein, at a point between the initial position and the terminal position, the detection protrusion is configured to extend through a hole in the opposite part of the cover and to assume the extended state, wherein the hole extends in the direction orthogonal to the rotational plane.
A cartridge comprising:
- a housing;
- a driving input member provided of the housing, the driving input member configured to be rotated by an externally supplied rotation driving force;
- a rotational member configured to receive the rotation driving force, which is transmitted from the driving input member, and be rotated thereby;
- a cover attached to the housing, the cover having an opposite part that faces the rotational member;
- and
- a detection protrusion provided at a position away from a rotational center of the rotational member,
- wherein the detection protrusion is configured to be changeable between:
- an extended state in which a pivot part of the detection protrusion is positioned at first orientation relative to a main body of the detection protrusion, and
- a collapsed state in which the pivot part is positioned at second orientation relative to the main body, which is different than the first orientation,
- wherein, at least a portion of the detection protrusion is configured to pivot about a pivot axis that is substantially parallel to a face of the rotational member that faces the cover in order to assume each of the extended state and the collapsed state.
