Abstract
PURPOSE:To execute checking efficiently by installing checking display tube(s) on the upper or lower position(s) of a calculation value display tube in a single row or plural rows, or on the upper or lower positions of the calculation value display tube in plural rows. CONSTITUTION:A calculation value display tube 2 is provided with checking display tube(s) 1 (in case of plural rows, the primary row is 1A and the secondary row is 1B) on its upper or lower position in a single low or plural rows or on its upper or lower position in plural rows and the number displayed on the calculation display tube 2 is transfered to the checking tube(s) by checking pushbutton(s) 3 (in case of plural checking display tubes, the primary pushbotton is 3A and the secondary is 3B) so as to be compared and checked with the subsequent checking value. The reason why plural checking display tubes are to be installed is that when the initial calculation value or the 2nd is incorrect, the 3rd calculation is required for checking which one is correct. Thus, the calculated results can be checked efficiently.
