Toner case for image forming apparatus

摘要

An image forming apparatus includes a toner container. The toner container includes an opening/closing portion and an operation portion. The image forming apparatus includes a drive transmission portion and a detection portion. When the lever of the operation portion is swingingly operated, the operation driving force of the operation is transmitted to the opening/closing portion via a first rotation portion and a second rotation portion. This allows a shutter cylinder to move from a closing position to an opening position. In addition, when the second rotation portion is rotated, a detected bar of the detection portion moves from a second position to a first position. The detection portion detects that a toner discharge outlet is opened, by detecting that the detected bar has moved to the first position.

主权项

1. An image forming apparatus comprising:
an apparatus main body; and a toner case configured to be attached to the apparatus main body, wherein the toner case includes:
a housing configured to store toner;a toner discharge outlet formed in the housing;an opening/closing portion provided in the housing and configured to open and close the toner discharge outlet; andan operation portion provided in the housing, the apparatus main body includes:
a drive transmission portion including: an input portion configured to receive a driving force input from the operation portion; and an output portion configured to output, to the opening/closing portion, the driving force transmitted from the input portion; anda detection portion configured to detect an opening/closing state of the toner discharge outlet, the operation portion includes
a first coupling portion configured to be coupled with the input portion of the drive transmission portion in a state where the toner case is attached to the apparatus main body, and transmit the driving force to the input portion, the opening/closing portion includes:
a second coupling portion configured to be coupled with the output portion of the drive transmission portion in the state where the toner case is attached to the apparatus main body, and receive the driving force from the output portion; anda displacement member configured to be displaced, by the driving force transmitted to the second coupling portion, between an opening position for opening the toner discharge outlet and a closing position for closing the toner discharge outlet, and the detection portion includes:
a detected member configured to be moved upon receiving the driving force from the output portion of the drive transmission portion and displaced between a first position corresponding to the opening position of the displacement member and a second position corresponding to the closing position of the displacement member; anda sensor configured to detect at what position the detected member is.
