PURPOSE: A shield box for testing a mobile phone is provided to minimize an occupancy space of a device and effectively shield an internal space. CONSTITUTION: In an initial stage, a door(30) of a shield box is opened. When a mobile phone is mounted on a mounting stand by a robot, the door(30) is closed in the following manner. A pneumatic cylinder(40) is driven and moved to a certain direction on a rod(41), and a cam block(43) is horizontally moved along with the pneumatic cylinder(40). At this time, a cam follower(32) inserted at a guide groove(43a) is moved. The cam follower(32) converts a linear motion of the cam block(43) into a rotational motion, and rotated along the guide groove(43a). Then, the door(30) is gradually rotated toward a mounting unit(21) by the cam follower(32) and mounted at an upper surface of the mounting unit(21), closing an upper opening. When a mobile testing is completed, the pneumatic cylinder(40) is driven to linearly moved in a direction 'B' along the rod(41), and at this time, the cam block(43) is moved together. The linear motion of the cam block(43) is converted into a rotational motion by the cam follower(32). Therefore, as the cam follower(32) is rotatively moved along the guide groove(43a), the door(30) is opened.
