An article shipment system 100 includes an automated warehouse 1, a picking area 2, a consolidation area 4, and a control system 5. The control system 5 alternately provides, to the automated warehouse 1, a transfer command to transfer a target mount with a higher picking workload from the automated warehouse 1 and a transfer command to transfer a target mount with a lower picking workload from the automated warehouse 1 to transport multiple first mounts to the picking area 2. The target mount is a first mount, among the first mounts, loaded with articles of a specified type included in a target article-specific order information group. The target article-specific order information group is a group of pieces of article-specific order information included in part of multiple pieces of order information among pieces of article-specific order information included in the multiple pieces of order information.

Disclosed are an anthracene derivative with a specific structure and an organic electroluminescent device including the anthracene derivative. The organic electroluminescent device includes a light emitting layer employing the anthracene derivative as a host compound and a polycyclic aromatic derivative with a specific structure as a dopant compound. The use of the host and dopant compounds allows the organic electroluminescent device to have a long lifetime and significantly improved low-voltage characteristics.

A polycyclic aromatic compound or a condensed multimer thereof, according to the present invention, is employed in an organic layer in an organoelectroluminescent device, thereby enabling the implementation of an organoelectroluminescent device having high efficiency and a long lifespan, and thus the present invention may be industrially useful in various display devices such as a flat panel display device, a flexible display device, a monochromatic or white flat panel lighting device, and a monochromatic or white flexible lighting device.

The endless path 4 includes: a first region 41 extending linearly in the transport direction X and constituting a transport surface 4F on which the object to be transported 9 is placeable, turn-back regions 43 in which the endless path 4 is turned back downward from respective end portions of the first region 41 in the transport direction X; and a second region 42 continuous with the turn-back regions 43 and extending in the transport direction X below the first region 41, and the second region 42 has, between the two support legs 31 in the transport direction X, a specific zone 42S that is parallel with the first region 41 and in which a spacing from the first region 41 in an up-down direction is smaller than a smallest turn-back dimension Lmin corresponding to twice a smallest bending radius Rmin of the endless member 5.
