Image Number 2 for United States Patent #5862441.
An image-forming machine comprises a movable mounting plate disposed in said machine housing in a manner to be moved toward, and away from, a photosensitive material drum, and a push-operation mechanism for moving the developing device mounted on the movable mounting plate between a push position close to said photosensitive material drum and a push-release position. The push-operation mechanism is equipped with a push lever disposed on the front side of the machine housing. When the push lever is brought to the first position on the upper side of the mounting surface of the movable mounting plate, the push-operation mechanism brings the developing device to the push position and when the push lever is brought to the second position of nearly the same height as the mounting surface of the movable mounting plate, the push-operation mechanism brings the developing device to the push-release position.
