Abstract
An example toner cartridge includes a housing to contain toner and having a toner outlet, a conveying member, a shutter to open and close the toner outlet, a driven coupler to rotate the conveying member and having an extension that extends in an axial direction, and a protruding member including a rotational force receiver installed in the extension so as to move to a protruding position in which the rotational force receiver protrudes from the extension and a retracted position in which the rotational force receiver is received into the extension in conjunction with opening and closing operations of the shutter.
Claims13
A toner cartridge comprising:
- a housing to contain toner therein and having a toner outlet;
- a conveying member;
- a shutter to open and close the toner outlet;
- a driven coupler to rotate the conveying member and having an extension that extends in an axial direction;
- a protruding member including a rotational force receiver and installed in the extension to move between a protruding position in which the rotational force receiver protrudes from the extension and a retracted position in which the rotational force receiver is received into the extension in conjunction with an opening operation and a closing operation of the shutter;
- an interference portion provided in the protruding member;
- and
- a coupler cover, connected to the shutter, to interfere with the interference portion as the shutter moves from a closed position toward an open position to move the protruding member from the retracted position toward the protruding position, and to interfere with the rotational force receiver as the shutter is moved from the open position toward the closed position to move the protruding member from the protruding position toward the retracted position.
A toner cartridge comprising:
- a housing to contain toner therein and having a toner outlet;
- a conveying member;
- a shutter movable between a closed position for closing the toner outlet and an open position for opening the toner outlet;
- a driven coupler to rotate the conveying member and having an extension that extends in an axial direction;
- a protruding member provided with a rotational force receiver and installed in the extension to be moved between a protruding position in which the rotational force receiver protrudes from the extension and a retracted position in which the rotational force receiver is received into the extension;
- and
- a coupler cover, connected to the shutter, to move between a protective position to cover the rotational force receiver of the protruding member located at the retracted position and a conversion position to allow movement of the protruding member to the protruding position as the shutter moves between the closed position and the open position.
