    摘要: A digital printer of the print wheel controlling type comprising a timing signal generator for developing type selection controlling signals (.alpha.) for selecting a desired type mounted on the print wheel, and a wheel round detection signal (.beta.) for indicating a complete one round of the print wheel. A print control circuit is provided for detecting whether the wheel round detection signal (.beta.) is developed next after the development of the type selection controlling signals (.alpha.) by a predetermined number. If the wheel round detection signal (.beta.) is not developed at a preselected timing, the print control circuit learns an erroneous printing operation, and functions to conduct a corrected printing operation.

    摘要: An electronic cash register operates either in a one clerk operation mode or in a two clerk operation mode wherein a first clerk performs the normal registration operation and a second clerk performs the resetting (accountant) operation. The electronic cash register includes a timepiece for automatically placing the electronic cash register in the two clerk operation mode when the current time reaches a preselected time.
