One-way physical-isolation disc conveying device

The invention relates to the field of information safety and discloses a one-way physical-isolation disc conveying device. The one-way physical-isolation disc conveying device comprises a manipulator, a source area disc arranging device, a target area disc arranging device and a one-way door. When moving at unload in front of the source area disc arranging device and the target area disc arranging device, the manipulator avoids contact with the one-way door; the one-way door is provided with a closing resetting device for closing an open door, and a limiting device for limiting the one-way door from being opened towards the side where the source area disc arranging device is positioned; when controlling the manipulator to load discs from the source area disc arranging device, a controller can open the one-way door to enable the carried discs to reach the side where the target area disc arranging device is positioned. The one-way physical-isolation disc conveying device can effectively convey the discs in one way to avoid information leakage due to outbound of security-level discs.
