Abstract
PURPOSE: To simplify the processing after operation restart, by discriminating whether the operation of calculator is made by the power off by the operator or automatic power off, and by determining whether the data before power interruption is cleared or stored with the result of discrimination.
CONSTITUTION: The data performing various operations is stored in the RAM 4 having entry registers, and the halt of operation performed by the opeation section 3 is constituted that it is by the interruption of the power switch SW or by the automatic power off signal APO of the ROM address section 8 for discrimination. Further, the state control unit 6 having the buffer register 16 connected to the key input section 1 and operated with the key input of the input section 1 and FF 25 operated with the output at the address section 8 and controlling the pulse generator 9, is provided, and it is discriminated whether the power suply is interrupted with the power switch SW or automatic power off depeding on the state of the unit 6 to determine whether the data before power interruption is cleared or stored to control the ROM 7.
