<p>PURPOSE:To realize digital indication with a simple constitution, by using a rotary disc whose circumferential edge section is provided with knotches at equal intervals, and by detecting the knotches. CONSTITUTION:When a load-applying object is placed on a load-receiving plate 2, Roberbel mechanism consisting of a plate-receiving metallic fitting 4 and a load spring 10 is actuated, and at the same time, an enlarging lever 11 is rotated in anticlock-wise direction. By the anticlock-wise rotation of the enlarging lever 12, a rack 16 is driven away from front surface of a housing 1. By horizontal shifting of the rack 16, a rotary disc 17 is rotated through a pinion 18, knotches 19 of the rotary disc 17 are detected by a detecting device 20, and digitalized figures from a decoder and an indication circuit are indicated on a digital indication unit 3.</p> |
