Abstract: A carrier transfer for automatically transferring a substrate carrier includes a gripper detachably coupled to the substrate carrier, the substrate carrier including a plurality of substrates and at least one open gate through which the plurality of substrates are loaded into or unloaded from the substrate carrier. The gripper includes a gate blocking unit secured to the gripper and configured to shift to a blocking position, the blocking position being a position of the gate blocking unit that partially blocks the gate to prevent the plurality of substrates from being separated from the substrate carrier during the automatic transferring of the substrate carrier.

Abstract: Disclosed is an automated-guided vehicle having a driver, comprising an emergency stop switch for selecting an emergency stop and a release of the emergency stop of the driver; a state detector part for detecting a selection state of the emergency stop switch; and an emergency stop driving circuit for stopping in emergency an operation of the driver or releasing the emergency stop thereof according to a detection signal from the state detector part. With this configuration, where an emergency situation such as stoppage of the CPU occurs, the driver of the AVG can be stopped by the emergency stop switch, and therefore, the AGV can be more safely stopped.
