Abstract
There is provided an electronic cash register comprising a keyboard including a plurality of entry keys and a plurality of transaction keys; a data-storing circuit; a printer; and a data-processing circuit for supplying the data-storing circuit and printer with information represented by operation of keys on the keyboard. The electronic cash register further includes a switch provided to set the operation of the data-processing circuit at the "registration" mode and "tax set" mode. When entry keys are operated with the switch positioned for the "tax set" mode of the data-processing circuit, then desired tax information is stored in a tax memory, and when a tax key included in the transaction keys is depressed after the entry keys are operated with the switch positioned for the "registration" mode of the data-processing circuit, then tax information on a taxable amount stored in the data-storing circuit by operation of the entry keys is read out of the tax memory.
