PURPOSE:To make possible adequate object control by operating an automatic scanner at the necessary time and calculating and announcing article quantities by the respective unit weights while causing total weight signal scanning from the load detectors of respective shelves. CONSTITUTION:The fluctuations in the total weight of every shelf 28 are detected at all times by each load detector 16. Thereupon, when the timer having been set by an hour timer 35, the total weight of every shelf 28 is sequentially scanned at every specified time from the shelf number S11 up to SNn by the operation of an automatic scanner 32 and is stored in a memory circuit 43 through an amplifier 35 and A/D converter 36. At this time, article quantities are calculated in an arithmetic circuit 44 based on the unit weight at a certain article number, the tare weight of the shelf 28 where this article is placed and its total weight having been stored in the memory circuit 43 and the article quantity of each shelf 28 is subsequently calculated by the operation of the automatic scanner 32 and is stored in the memory circuit 43. These are then displayed together with items 46-50 in a display part 51. |
