A shield door for an electromagnetic wave shield room is provided to restrict access to an electromagnetic wave shield room, to prevent noise occurrence by using a shield device as an actuator, and to minimize a space required for shielding. A shield door(10) for an electromagnetic wave shield room comprises a door main body(100), an operation part(200) and a fixation part(300). The door main body is fixed with a doorframe(110) fixed to a wall of a shield room by a hinge to be movable on the doorframe. The operation part is composed of a security module(210), which comprises a recognition part(212) approving the access of people entering and leaving a shield room and an indication part(214) indicating the opening and closing of a shield door, and a drive module(220) which comprises an actuator(224) operated by the approval of the security module, and a rack(221) and a pinion(222) operated by the actuator. The fixation part is composed of a fixing block(310) provided to the doorframe and provided with a fixing groove(311) and an insertion groove(312), and a movable shaft(320) provided to the door main body in the vertical direction to reciprocate by the drive module and provided with sensors(326a,326b) to detect the movement of a fixing pin(322). |
