<p>PROBLEM TO BE SOLVED: To provide a device for displaying the situation of bidding so that applicants for bidding can always perform confirmation easily. SOLUTION: In the bidding situation display part 13 provided on the control panel of a coordinator, an LED having at least two light sources whose emission colors are different is adopted as a pixel 61 and the part 13 is constituted by arranging pixels by 1024 pieces of them in total in 32 rows and 32 columns. When the number of applicants (the number of sets of control panels of buying shops which are being used) transmitted from a bidding controller is larger than a quarter of the maximum number of persons (1024 persons) which can be displayed by the display part 13, the control part of the control panel makes the number of pixels which are to be allotted to one bidding person to be 1. When the control part receives data which indicates the control panel of a buying shop being used for the bidding by a bidder from the bidding controller, the part lights up a pixel 61 corresponding to the control panel and, also, lights up pixels 61 surrounding the lighted pixel 61.</p> |
