    摘要： A weighing scale is provided in which a horizontally disposed weighing platform contains a weighing scale dial on a side of said platform so that it can be read both from directly above and from the side, and means for transmitting weight response from a weighing mechanism mounted beneath said platform to said dial.

    摘要： A low cost, light weight drum type optical encoder for producing a digital manifestation of the position of a shaft, such as the indicator needle shaft of a gauge or a weighing scale, comprises a small light weight dish with a strip of material, such as plastic or metal having coded optical transmissivity or reflectivity thereon, held to the flanged rim of the dish by a shrunken ring retainer. Light passing through a slit is transmitted by or reflected from the code drum in a coded fashion to be sensed by appropriately disposed photodetectors, the signals from which are used in any digital fashion.
