Abstract
Equipment for reading-out the setting of number wheels of a number barrel mechanism with switching pinions on an axle within the circumference of number wheels. Via the switching pinions the respective lower value number wheel in the last scale part of its revolution rotates the higher value number wheel forward by one scale part. With a respective opti-electronic element within the number wheels and peripheral optical elements, several radial light barriers are formed for each number wheel. The number wheels have translucent code segments and opaque code segments. During sequential reading-out, binary information data are formed in Gray code and the read-out data are processed further in a microprocessor.
