To provide a loading and unloading machine that enables a person to safely and efficiently load and unload a cargo by himself or herself.

In a loading stroke, a front end of a moving type top plate 1 is drawn by a moving type top plate drawing device 4 to be moved up while sliding on a movable column 2, and the loading stroke is completed while a loading/unloading direction stabilization device 3 and an abrupt angle change suppression device 5 suppress right-left swings and abrupt changes in angle that may occur in the movable column 2. At the completion of the loading stroke, basic components 3, 4, 5, and 6 are stored in a stored state under the moving type top plate 1. In an unloading stroke, the movable column 2 and the moving type top plate 1 applied with a force in a push-out direction by an elastic body 6 are moved to angle change start positions by driving a moving type top plate pull-up device 4 in a pull-down direction, and then, the unloading stroke is completed with its own weight after the start of the angle change.
