PROBLEM TO BE SOLVED: To provide a system to enable effective utilization of a chamber picture of a food preservation chamber to a user and effective utilization of it for economical procurement for an insufficient food and a necessary food. SOLUTION: By photographing a chamber picture by a camera 201 situated in a refrigerator 100, the picture is held in a data base 110. When a call of the chamber picture from a portable terminal 300 of a user through an information network 7 is effected, the recorded chamber picture is transmitted to the portable terminal. The chamber picture is displayed at the portable terminal. When there is a feed material insufficient to a user, a food information data base 2 is retrieved by making access to an at-home server 1, and a shop to provide the food is abstracted at a low cost to display it at the portable terminal.
