Abstract: A picking cart and a picking system capable of improving sorting precision and operating efficiency. The picking cart comprises a plurality of storage shelves at least one of which has a container placed thereon in a drawable manner, a display unit for displaying at least an article to be picked and one of the storage shelves to which the article is to be delivered, a sensor unit for detecting whether or not the container placed thereon has been drawn from each of the storage shelves, and a determination unit for determining whether or not one of the storage shelves from which the container placed thereon has been drawn is identical to the storage shelf displayed on the display unit, based on the detection result of the sensor unit. Before an article is placed in a container, that is, when a container is drawn, it is possible to know whether or not sorting has been carried out just as displayed.

Abstract: A work progress display device and method capable of maintaining work efficiency of a worker by encouraging the worker to work. The work progress display device comprises a storage unit for storing a capability value indicating work capability of a worker, a calculation unit for calculating, in accordance with the capability value, a standard value serving as a work standard of the worker, and a display unit for displaying actual work progress of the worker as an actual performance value, and the display unit displays the standard value so as to be able to be compared with the actual performance value. By looking at this device, a worker can compare actual work progress with his or her work standard determined by his or her capability and check a difference.

Abstract: A novel steering mode switching carriage is disclosed. A plurality of such carriages, if coupled to each other, can follow a single path without developing any discrepancy in turning radius between front and rear inner wheels when traveling on a curve. The carriage is used as a conventional cart if the front wheels are made to pivot freely and the rear wheels are fixedly aligned longitudinally. According to the present invention, a pair of pivotal shafts of the front wheels and a pair of pivotal shafts of the rear wheels are coupled by right and left parts of a reversing mechanism respectively. Each pivotal shaft is provided with an engaging member, which has a slider and a link lever extending therefrom. The front wheel is caused to pivot by the slider, and the reversing mechanism and the slider are coupled to each other by the link lever.
