The invention is embodied, for example, as an electronic cash register (ECR). The ECR is at least provided with numerical keys and a buzzer. When data relating to the prices of goods to be registered is entered with use of the numerical keys, the total sum payable by the customer is calculated and stored in a memory. When a sum received is entered with use of the numerial keys, the sum is similarly stored in the memory. The ECR has a CPU which compares the received sum keyed in with a pattern predetermined based on data relating to the kinds of money in circulation and checks whether the received sum is acceptable relative to the total sum. The buzzer goes on when the received sum is not acceptable.

An electronic cash register for printing designated data includes a keyboard having a plurality of keys. The keyboard has a switch for designating a write-in mode and a read-out mode and a plurality of keys including ten keys, function keys, etc. The data coupled by the operation of these keys are stored in the journal memory. The data to be read out in the read mode are stored in a register included in a CPU. The CPU performs a comparison of the data from the journal memory and the designated data read out from the register in the CPU in its calculating section and, when the compared data coincide, the read-out designated data are output for display in a display section or printing in a printing section.

An electronic cash register comprises a memory having a plurality of registering regions each allotted for each of the commodity departments, and a keyboard including numeral keys, whereby any of the registering regions of the memory are set to be utilizable by means of the keyboard.

The registering regions corresponding to the respective commodity department codes between the first commodity department code and the last commodity department code are in succession designated by an address counter, and the restricted number of digits of the unit prices is loaded in the designated registering regions, whereby the series of the consecutive registering regions are set to be utilizable.

A cash accounting system which includes a cash register for registering transactions of money and a cash dispenser coupled with the cash register for dispensing an amount of money required to be paid out during the respective transactions.
