Abstract
management device for managing the expiration date of food and drink arranged on a plate and including a camera for capturing a two-dimensional code on a cylindrical base of the plate, a barcode scanner for analyzing the two-dimensional code captured by the camera and extracting a plate number, a management main body for receiving the plate number output from the barcode scanner and collectively managing the traveling plates, and a DIO (Digital Input/Output) module. The DIO module is connected to a detection switch disposed on a downstream position of the camera and a discharge mechanism disposed on a downstream side of the detection switch to perform a bidirectional communication with the management main body. A separation distance between the camera and the detection switch is shorter than a diameter of the plate.
