Unit attaching/detaching structure and image forming system
A unit attaching detaching structure includes: a unit that is attachable to and detachable from an apparatus main body; a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side; a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side; a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion; a movement portion that is provided on the unit and displaces the displacement portion by moving the connecting portion when the unit is attached to the apparatus main body; and a returning unit that returns the displacement portion when the unit is detached from the apparatus main body.
1. A unit attaching/detaching structure, comprising:
a unit that is attachable to and detachable from an apparatus main body;
a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side;
a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side;
a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion to be moved;
a movement portion that is provided on the unit and displaces the displacement portion from the another side to the one side by moving the connecting portion when the unit is attached to the apparatus main body; and
the connection portion comprising a returning unit that returns the displacement portion from the one side to the another side when the unit is detached from the apparatus main body,
wherein the displacement portion is displaced toward the detection unit when the unit is attached to the apparatus main body.
2. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
the unit that is attachable to and detachable from a main body of the image forming apparatus by the unit attaching/detaching structure according to claim 1 and to which the recording medium is output from the apparatus main body while the unit is attached to the apparatus main body.
3. A unit attaching/detaching structure, comprising:
a unit that is attachable to and detachable from an apparatus main body;
a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side;
a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side;
a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion to be moved;
a movement portion that is provided on the unit and displaces the displacement portion from the another side to the one side by moving the connecting portion when the unit is attached to the apparatus main body; and
the connection portion comprising a returning unit that returns the displacement portion from the one side to the another side when the unit is detached from the apparatus main body, wherein
the connecting portion is formed of a plate spring as the returning unit, comes into contact with the movement portion and elastically deformed by being pressed against the movement portion when the unit is attached to the apparatus main body, and is separated from the movement portion and elastically returned when the unit is detached from the apparatus main body.
4. The unit attaching/detaching structure according to claim 3 , wherein
the connecting portion is in a cantilever state, and
a free end side of the connecting portion is connected to the displacement portion.
5. A unit attaching/detaching structure, comprising:
a unit that is attachable to and detachable from an apparatus main body;
a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side;
a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side;
a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion to be moved;
a movement portion that is provided on the unit and displaces the displacement portion from the another side to the one side by moving the connecting portion when the unit is attached to the apparatus main body; and
the connection portion comprising a returning unit that returns the displacement portion from the one side to the another side when the unit is detached from the apparatus main body,
wherein when the movement portion and the connecting portion come into contact with each other, the connecting portion is electrically connected to the apparatus main body.
6. The unit attaching/detaching structure according to claim 5 , wherein
the apparatus main body is a main body of an image forming apparatus that forms an image on a recording medium,
the unit is a unit to which the recording medium is output from the apparatus main body, and includes a transport unit that transports the recording medium while rotating, and
when the movement portion and the connecting portion come into contact with each other, the transport unit is grounded.
