A semi automatic swing hinge module is provided to open a front case with respect to a rear case by using an operation of a cam formed on a circumference of a rotating member and an elastic restitution force of a tensile spring. A semi automatic swing hinge module comprises a fixed member(4), a rotating member(5), a sliding member(6), an elastic member(7), and a guide member(8). The fixed member(4) forms a cylindrical protrusion with a certain height vertically on its one face. The rotating member(5), inserted around a circumference of the protrusion of the fixed member(4), forms a cam with a certain shape on its circumference. The sliding member(6), positioned between the rotating member(5) and the fixed member(4), is guided to the cam of the rotating member(5) and performs a linear motion according as the rotating member(5) rotates. The elastic member(7), whose one end is fixed at the fixed member(4) and the other end is fixed at the sliding member(6), offers an elastic force such that the rotating member(5) rotates a certain angle and then automatically 180 degrees from an initial position. The guide member(8), combined with one face of the fixed member(4), guides the sliding member(6) and the elastic member(7) while the guide member(8) is hooked at the sliding member(6) and the elastic member(7).
