A laboratory sample distribution system comprising sample container carriers, a central controller having a network interface, and transport modules is presented. Each transport module comprises a transport surface, wherein the transport surfaces form a transport plane, a controllable driver arranged below the transport surface and configured to move sample container carriers on the transport surface, and a control unit for controlling the driver. The control unit comprises a network interface. The central controller and the control units of the transport modules are connected by their corresponding network interfaces. Each control unit comprises first and second addressing terminals. The addressing terminals are connected sequentially in a daisy chain topology. The first addressing terminal is the first control unit in the sequence and is connected to a first reference potential and the second addressing terminal is the last control unit in the sequence and is connected to a second reference potential.

In order to easily identify a specimen to be extracted because, for example, an item remains uninspected, from a rack 31 collected in a storage part 13 or the rack 31 taken out from the storage part, a camera of a smart device takes an image of the rack; and a calculation unit included in the smart device provides a mark, by AR technology, at the position of a specimen to be extracted. For example, the item that remains uninspected is identified on the basis of information about a combination of a rack ID and an identifier and information, which is received from an operation unit about specimens at respective positions. Thus, irrespective of a place or whether the specimen to be extracted is inside or outside of the device, the specimen to be extracted can be reliably specified from a plurality of specimen containers provided on a holder.
