Abstract

PURPOSE: To display the count value of electric pulses, and also to display its unit by changing units by a numeral registered by a key of an electronic desk calculator and also by changing the exponent part of a display register.
CONSTITUTION: This calculator is provided with keyboard 1, registration and arithmetic instruction circuit 2, control circuit 3, arithmetic register 4 and display circuit 6 connected to addend part 5 and exponent part 5-1 of the display register; the output of detection part 7 generating a binary electric signal and that of 1st FF9 are inputted when both the output signal disagree, dissidence detection circuit 8 generates a pulse to invert FF9. Further, 2nd FF10 is provided which resets by a signal from keyboard 1 and set on the arrival of an execution instruction to the circuit which registers "1" in addend part 5 of the register and when a pulse from circuit 8 arrives. FF10 is set to add "1" to the content of addend part 5. Then, while FF10 is in a reset state, the output of change-over switch 15 is applied to exponent part 5-1 of the register, thereby changing units.
