PURPOSE:To enable recognition of even the condition of the change of past weights by a method wherein weight data are converted into graph data by using a micro-processor, memorized in a memory, called out and displayed by a digital annunciator. CONSTITUTION:The signal of a load cell 27 is inputted to an A/D converter 30 through an amplifier 28 and count data are obtained from a control circuit 53, weight value is calculated by the micro-processor 33 on the basis of the data while being held for a fixed time in an RAM in the micro-processor, and the value is converted into predetermined graph data and memorized to the memory. The data are called, and displayed to the digital annunciator 3, to which a plural digit of day type segment display elements are arranged, through the operation of an operating section 2. Accordingly, not only weight being weighed at present but also the conditions of changes in past weight can easily be grasped, and only one annunciator 3 may be used and practicality can largely be improved. |
