Abstract
A roller device may include a main body, a first roller configured to rotate around an first axis line extending in a predetermined axial direction, the first roller including an end portion in the axial direction, and a supporting member including a first supporting portion configured to rotatably support the end portion of the first roller and an engaging portion configured to engage the main body. Further, the main body including a regulating portion disposed inside the movable range when the supporting member is located at a third position and disposed outside the movable range when the supporting member is located at a fourth position.
Claims33
A roller device comprising:
- a main body;
- a first roller configured to rotate around a first axis line extending in a predetermined axial direction, the first roller including an end portion in the axial direction;
- and
- a supporting member including a first supporting portion configured to rotatably support the end portion of the first roller and an engaging portion configured to engage the main body,
- wherein the first supporting portion is movable within a movable range between a first position and a second position, the first supporting member supporting the end portion of the first roller at the first position, and the first supporting member being disengaged from and disposed outside of and adjacent to the end portion of the first roller at the second position,
- wherein the supporting member is movable between a third position and a fourth position, the engaging portion engaging the main body when the supporting member is located at the third position, and the engaging portion being disengaged from the main body when the supporting member is located at the fourth position, and
- wherein the main body including a regulating portion disposed inside the movable range when the supporting member is located at the third position and disposed outside the movable range when the supporting member is located at the fourth position.
A roller device comprising:
- a roller having an engaging portion;
- a first supporting portion configured to rotatably support the engaging portion of the roller, wherein the first supporting portion is configured to be movable in a moving range between a first position in which the engaging portion is supported by the first supporting portion and a second position at which the engaging portion initially becomes disengaged from the first supporting portion;
- and
- a regulating portion positioned within the moving range of the first supporting portion between the first position and the second position.
A roller device comprising:
- a roller having a shaft;
- a supporting portion having a bearing configured to receive and rotatably support the shaft, wherein the supporting portion is configured to move within a range between a first position in which the shaft is received in the bearing and a second position in which a surface of the bearing facing the roller, in an axial direction of the roller, is located at an axial end surface of the shaft;
- and
- a regulating portion located within the moving range of the supporting portion.
A roller device comprising:
- a roller having a recess;
- a supporting portion having a shaft configured to be received within the recess of the roller, wherein the supporting portion is configured to move within a range between a first position in which the shaft is received in the recess and a second position in which an axial surface of the roller adjacent to the recess is located at a same axial position as an end surface of the shaft;
- and
- a regulating portion located within the moving range of the supporting portion.
