A computing and recording register wherein integrating digital counters are driven by an input shaft to perform quantity, price and tax computations. The price and tax counters are driven by computer gearing coupled to the quantity counter drive gearing through a clutch. A two-stage advance mechanism rounds off the least significant digit of each of the counters and aligns the digits for printing quantity, price and tax data on a recording sheet at the conclusion of each transaction to be recorded. During the first stage, the quantity counter is advanced to align the digits while the clutch is engaged so that the price and tax counters are driven as the quantity counter advances. During the second stage, the clutch is disengaged and the price and tax counters advance independently of the quantity counter.
