PURPOSE:To effectively use a desk computer and an electronic cash register ECR by a simple operation, by constituting so that a result which has been operated as a computer can be inputted as registering information of an ECR directly, and using the information which has been registered as an ECR, as an electronic disk computer. CONSTITUTION:When a switch 11e is operated, an FF9 is set, and a flag is set to an area 31 in a CPU3. The CPU3 reads out a program for an electronic cash register ECR from an area 41 of an ROM4, and executes an operation of an ECR. In this case, when a transaction is arranged, quantity information and unit price information are inputted from a numerical key 1a of a keyboard, and a calculation of quantity and unit price is executed by the CPU3. When the transaction is finished, the CPU sums up a registration data, prints 6 it, and also displays 7 it. In this way, since a registration data or an arithmetic operation result can be utilized as an operation data or a registration data as it is, such a complicated operation as inputs a calculation result by a computer to an ECR over again is made unnecessary. |
