PURPOSE:To obtain small size unit which can perform various complicated control for other unit, by organically coupling the timing function of electronic type timing unit with various operation functions of electronic desk top calculator. CONSTITUTION:The input means 1 inputting required information for the calculation of calculator, reference time generator 3 generating the reference time, and operation state selector 2 selecting the clock operation and various calculation operation, are provided, and the timing generator 4 producing various timing pulses required for the entire operation is provided. Based on the information from this means 1 and the generator 3, in the operation circuit 10, the arithmetic operation and time operation of input information is respectively made, the result of timing operation is stored to the timing information 13 of the main memory unit 5 with the indication of the operation control section 8, the information 13 is renewed when the pulse from the pulse generation circuit 9 is present, and it is stored to the timing information 13 of the main memory unit 6. Further, by selecting the control section 8, the result of operation of the input information is stored to the numeric information 14 of the unit 5, and the result of operation is displayed on the display circuit 12. |
