ABSTRACT:
An electronic cash register has first and second total memories for storing data of accumulated sales amounts, and which is capable of two different types of settlement operations. It checks whether the first total memory has been reset before commencing the operation of resetting the second total memory, and resets the second total memory if the first total memory has been reset. A flag memory is provided for storing flag data such that when no flag data is stored in the flag memory upon actuation of the second settlement designation key, the total sales data in the first total memory is cumulatively stored in the corresponding memory areas of the second total memory and thereafter the data in the second total memory is supplied to the printing means.
