• wherein the hinge unit comprises,
• a connection portion projected from one end of the support body;
• a hinge rotatably coupled to the connection portion;
• a cylinder connected to the hinge and loaded in the electronic body;
• and
• a hinge spring having one end fixed to the cylinder and the other end supporting the electronic body to generate a restoring force for the electric bodies from the drawn-out state to the drawn-in state, and
• wherein the electronic body is caught to the connection portion in case of the drawn-into state such that the electronic body is restricted to rotate.
