LEAF SPRING WEIGHING SCALE WITH OPTICAL DETECTOR Abstract of the Disclosure A weighing scale having a tare structure carried by a pair of vertically spaced parallel leaf springs includes an optical detector having an apparatus for generating a moire fringe pattern and moving the pattern with scale tare deflection. One of a pair of ruled parallel grating sets is fixed while the other is mounted to the tare structure in movable, parallel alignment with the fixed set. A beam of light projects through both grating sets to project the pattern on a photodetector array carried by the scale frame. Upon placement of a load on the scale, deflection of the tare structure results in linear movement of successive fringes across the photodetectors and the sequential generation of weight indicative signals. The photodetectors are secured to a rotatable base for adjustment of the effective spacings between each photodetector with respect to fringe pattern image.
