PURPOSE: To enable the supplying of necessary food trays automatically by a method wherein the type and the number of food trays on a crescent chain are measured and points with no food tray from a food tray conveying mechanism are sensed with a sensor to halt the food tray temporarily with a stopper to supply. ;CONSTITUTION: Sushi 44 is placed on an empty tray 22 on a conveyor 16 of food tray conveying mechanisms 20 as indicated by A-D. The type and number of food trays 24 being conveyed in circulation on one cycle of a crescent chain 14 are measured with a measuring sensor 34 and for example, the food tray conveying mechanisms 20 having the food trays absent placed thereon as indicated by A and C are selected. Then, points with no food tray 24 on the crescent chain 14 are sensed with a sensor 32 and a stopper 30 is lifted from below the crescent chain 14 to halt the conveying of the food trays 24 temporality so that a space enough for the number of food trays 24 to supply is formed. During the period, the food tray conveying mechanisms 20 as indicated by A and C are driven to supply the food trays 24 then found absent.;COPYRIGHT: (C)1996,JPO
