A food and drink managing device with a circulation type path allows
standardizing while adding food and drink onto the carrying path,
simplifying management, holding down cost, and achieving precise
identification information reading. The food and drink managing device
with a circulation type carrying path has containers with identification
information, an identification information reading means provided near
said path, a sign part circularly moving as linked with said circulating
carrying path, passage detection means for detecting passage of said sign
parts, a registering means which recognizes an interval between passing
sign parts as one zone, and registers the identification information of
the containers read by said reading means, as foods and drinks being
supplied, in relation to a zone in which the containers exist, and a
container throwing-in prohibited area of a given length provided in the
upstream side of the circulating carrying path from a position of the
reading means.
