PURPOSE:To make it possible to record the measured value and the date and time instantaneously, by providing a measuring circuit, which outputs an electric signal corresponding to the measured weight, a clock circuit with a calendar, a microcomputer, which operates these values and stores the results, and a printer. CONSTITUTION:In a unit A, electrodes 3 and 4 of a measuring capacitor C are fixed to a chassis case 1 and a case lid 2, on which a person to be measured rides. The case 1 and the lid 2 are linked through springs 5. A distance (t) between the electrodes 3 and 4 is changed to decrease with the increase with a load on the lid 2. A measuring circuit 8 comprises a CR oscillator 6 including the measuring capacitor C. A clock circuit 9 with a calendar outputs the measured date and time. A microcomputer 100 operates these values and stores the results. A printer 10 prints the measured values and the date and time. Thus the weight and the date and time can be grasped by the accurate numbers in detail.
