Unit attaching/detaching structure and image forming system

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.
