Abstract

PURPOSE: To simplify the display device, by displaying the display tube for alarm with flickering in a period delayed, at the production of error due to overflow and malfunction, through the slight change to a part of circuit in the shift register group of an electronic computer.
CONSTITUTION: The keyboard 1 and the display device 3 in 9-digit are connected to the main body 2 of electronic computer, and the main body 2 is provided with the control section 4 taking CPU as the major body, shift register group 5 consisting of shift registers and display control section 6. This register group 5 is constituted with the n-digit register of basic constitution, (n-1)-digit of registers inputting sectioned error signal, and AND circuit coupling the output of the registers, and the input of the segment decoder 8 of the section 6 and the two signals of different period inputting to the code control circuit 7 are output to the output of the register group, enabling to display the error display with the period delayed than the data display. The period of signal inputted to the AND circuit of error display is taken as m-digit's share, allowing to change the period of flickering.
