PROBLEM TO BE SOLVED: To reduce manufacturing cost or maintenance cost by dispensing with setting of data depending on the machine model or the like. SOLUTION: A visual line position detection part 225 detects a visual line position at which a customer's visual lines intersects with the casing outer surface of a commodity sales device 1 based on an image acquired from a camera 11, and accumulates visual line data containing the position data in a visual line data storage part 32. Meanwhile, when a sales management center device 5 holds data in which identification data of sample display parts are associated with arrangement position data thereof in a mesh definition data storage part 77, and a data collection part 61 collects visual line data accumulated in the visual line data storage part 32 of the commodity sales device 1 at predetermined time intervals through a network 4, a gazed object detection processing part 62 refers to the mesh definition data storage part 77 and determines in which of sample display parts 20 the customer's visual line position in the collected visual line data is contained, and detects the sample display part 20 the customer gazes.
