- the operation panel 40 includes, for example, an operation reception unit that receives operations from a user, and an information output unit that displays information for the user on a screen or outputs audio.
- the operation reception unit includes physical buttons for receiving operations from the user, a touch screen, a microphone for voice input, and the like.
- the information output unit includes, for example, a display device and a speaker.
- the reception device 50 receives an operation for warehousing an article received from the user by the operation panel 40 or an operation for taking out an article from the user, and performs various controls.
- the reception device 50 has a window 42 for warehousing or delivery of goods. Articles that have been stored by the user at window 42 can be transported to the storage area by an automatic transport device. In addition, articles stored in the storage area can be transported to the window 42 by an automatic transport device.
