The present invention relates to a mapping module with higher precision, and a door assembly of a load port including the same. Since a mapping arm is directly combined with a power generating unit without an extra relay unit such as a gear, precision is excellent and durability is significantly improved. Since the mapping arm rotates at a preset rotation angle but includes a hooking unit, touching the mapping arm, in a position forming an allowable maximum rotation angle, an error by rotation angle is efficiently prevented. A latchkey module installed on a door plate is included, and power, generated through one power operating part, is delivered to a latchkey through a shaft without an extra relay unit, and therefore, the number of relay units to deliver the power is minimized to increase the precision of control. The latchkey module controls a rotatable range of the latchkey and a movable range of the shaft according to the length of a support rod insertion hole, and therefore, the rotation of the latchkey is precisely controlled. |
