Abstract
PURPOSE: To perform effectively the operation for key operation input by providing a display means which can display the number of memories, which can be used newly, and displaying states of memories dependent upon key operation after key operation.
CONSTITUTION: Stacks for display, operation and mathematical expression are provided in the register or the data memory of memory part 3 of an electronic desk calculator having key input part 1, operation control part 2, data memory part 3 and display part 7, and data memory numbers are assigned to them respectively. The total number of data memories is stored in storage part 4 for the total number of data memories, and the number of using data memories is stored in storage part 5 for the number of using data memories, and respective outputs are applied to adder and subtractor 6. The number of memories which can be used newly is calculated by this adder and subtractor 6 and is displayed on display part 7 through control part 2, and the state of memory part 3 for key operation inputted to input part 1 after that and is displayed, thus executing effectively the operation dependent upon key operation.
