摘要： An electronic cash register includes thirty department keys for identifying the department of the commodity purchased by the customer. A department memory has ninety memory sections each of which stores the unit cost information and the total amount of the transaction related to the commodity of a specific department. Three department level keys are provided to divide the department memory into three groups. When the first department level key is selected, the thirty department keys correspond to the first through thirtieth memory sections in the department memory. When the second department level key is selected, the thirty department keys correspond to thirty-first through sixtieth memory sections. When the third department level key is selected, the sixty-first through ninetieth memory sections correspond to the thirty department keys.
