(A structure in which a light emitting element and a light receiving element are arranged above and below) are arranged, and the electric carriage 2 is configured to pass through the package sensor frame 1. That is, the electric trolley 2 is, for example, equipment installed around an article shelf in an automatic warehouse, and is configured to appropriately move the article (article 10) loaded on the electric trolley 2. The pallet on which the article 10 is placed is placed on the pallet placing portion 2 a on the support pillars erected at the four corners of the electric carriage 2, and the trolley 2 can travel on the rail 21. Then, when the electric trolley 2 passes below the package sensor frame 1, the package 10 is detected based on whether or not the article 10 on the pallet is detected by the optical sensor 4.

問題があった。[0006] This conventional method of detecting a package is based on a bulky package detecting device having a gate-shaped gantry.
The moving operation of the electric trolley 2 is required, and if there is an abnormality in the package by detection using the optical sensor 4, an error is determined and the system is stopped. In addition, this requires the movement of the carriage (movement passing under the gantry) for detection,
A large installation place is required, and moreover, machines and control devices are expensive. That is, in the conventional detection device, the mounting space is large, and the load (electric trolley or conveyor) is moved for detection. Therefore, when a package error occurs, the transport system stops, and the package is corrected. In addition, there were problems such as the need to restore the transport system.
