A device for loading and unloading a machine-tool with tools, the tools being mounted in a tool store and being transportable via a manipulation device, which is particularly movable along multiple axes to a transfer position on the machine tool or in the machine tool and, after use in the machine tool, being removable therefrom, and the manipulation device having a gripper device for receiving the tools. To save weight and increase the access speed of the manipulation device, the manipulation device has at least one displacement arm movable in a preferably horizontal first movement direction, which is mounted so it is displaceable on a guide element, and the gripper device is mounted so it is displaceable on the displacement arm in this first movement direction.
