PURPOSE:To improve unit cost setting operation by installing a multiplying part, which multiplies unit cost information from a unit cost setting part by K times, between a unit cost information input and unit cost setting parts, detecting the completion of keying-in of the stated number of digits and changing magnification K of the multiplying part automatically. CONSTITUTION:Signals from input terminals K1, K2 and K4 and output terminals R0-R3 are converted into a registered value in encoder 7. Unit cost register 8 shifts one digit out of the stored contents upwards in every time when any one of switches SW0-SW9 is depressed and stores the newest register value out of the output from encoder 7. Multiplying part 9 multiplies the contents of unit cost register 8 by K times and outputs the value. Price operation part 10 calculates the price of the object to be measured from unit cost information Da and weighting information Dg outputted from unit cost register 8 through multiplying part 9. When the completion of keying-in of the stated number of digits is detected, magnification controlling part 11 changes magnification K. Thus, the unit cost setting operation can be extremely improved. |
