Claims (1)

[Claims for Utility Model Registration] (1) A sensor circuit that outputs a detection signal according to a measured value, and a sensor circuit that digitizes and performs arithmetic processing on the detection signal, thereby generating the first digit of the ones based on the detection signal. Signal A0~A
an arithmetic processing circuit that outputs second digit signals B1 to B9 of 9 and 10 digits; a cumulative display circuit that outputs cumulative display signals C1 to C19 representing the sum of the value of the first digit signal and the value of the second digit signal; and the first digit signals A0 to A9 and the second digit signals B1 to
B9 is inputted, and a multi-digit display circuit outputs multi-digit display signals E1 to E19 made up of the first digit signal and the second digit signal;
1 to E19 are input, and when the arithmetic processing circuit does not output a specific second digit signal corresponding to a preset value or more, the cumulative display signals C1 to C19 are input, and when a specific second digit signal is output, the cumulative display signals C1 to C19 are Display signal E
1 to E19 as display signals S1 to S19, and at least the same number of display elements as the total number of cumulative display signals C1 to C10 are arranged in parallel, and display signals S1 to S19 from the display switching circuit are arranged in parallel. A bar display device comprising: a display circuit unit that lights up a corresponding display element; (2) By setting the number of display elements to 19 and setting the preset value to 20, the display of less than 20 becomes a cumulative display, and the display based on the multi-position display signals E1 to E19 that displays a value of 20 or more is made. In doing so,
As the multiple digit display signals E1 to E19, the number of display switching circuits is N (N≦9) corresponding to the value of the second digit signal.
An H level lighting signal is output from the 1st output terminal to the Nth output terminal, and at the same time, the lighting signal is output from the N+2nd output terminal to the N+M+1th output terminal, which is M number (M≦9) corresponding to the value of the 1st digit signal. 2. The bar display device according to claim 1, wherein the bar display device outputs an H-level lighting signal to the number output terminal.
