To improve the working efficiency by operating two processes at the same time and to increase the attention of the picking worker and prevent a misoperation by processing picking command information through different aural and visual senses of the worker.

A dolly 10 of this cart for object picking work includes a speaker 13 for outputting picking command information by voice and voice input/output control means 15 for voice synthesizing and outputting next picking command information while previous command information is being displayed on a liquid crystal display screen 14. Then a picking worker picks a necessary item while recognizing visually one piece of picking command information on the screen 14 at the same time can determine the next destination by recognizing aurally the next picking command information that is output from the speaker 13.
