Abstract

PURPOSE: To increase the effect of mass production for the parallel binary code sending circuit of a fixed digit of 2N (N: a positive integer), by providing two sets of the N type transmission coding circuits and then connecting the transmission terminals of the both circuits with the sequence reversed to each other.
CONSTITUTION: The 1stW8th digits of the transmission code are sent to the terminals C0WC7 of the coding circuit COD-A(#1) corresponding to the push-buttons PB00WPB24. And the 8thW1st digits of the transmission signal are sent to the terminals C0'WC7' of the coding circuit COD-A(#2) corresponding to the push- buttons PB25WPB49. In other words, the output terminals of the circuits #1 and #2 are connected with the sequence reversed to each other. Thus the arrangement of the diodes corresponding to the push-button PB25 is identical to the arrangement of the diode corresponding to the push-button PB00 (transmission code 11100000), but the transmission code becomes 00000111. So is with the subsequent push- buttons, and the PB24 has the same arrangement of diodes as the PB49 with the inversed digits of the transmission code to each other. As a result, just one type suffices for the coding circuit, thus increasing the effect of mass production.
