Abstract

PURPOSE: To deliver the error signal when the detector is not operating for the left or right page and then to supply the data according to the key operation only when the page is set correctly to the right or left side.
CONSTITUTION: Key switches P1WP11 are provided at the left side, and each output is connected to the encoder circuit to deliver the page data. Each output of the other side of switches P1WP11 is connected to the corresponding output each as well as to the positive power terminal to form 11 pairs of the wired OR circuit of the negative logic. Each of these OR circuits is connected to the input terminal of the negative logic diode AND circuit, and the output is delivered in the form of the error signal. As a result, the data input is given according to the key operation only when the pages are set correctly to the right and left sides respectively.
