Abstract

PURPOSE:To prevent the coincidence of outputs of all FFs at the application of power supply, by setting the output of at least one FF out of a plurality of delayed type FFs to a different output from other FFs compulsively. CONSTITUTION:Outputs X1-X5 are at L when channel buttons 7-11 are depressed, and the signal at L level becomes an address designation signal of a preset memory to select corresponding channels. In this case, all delayed type FFs 1-5 are at L at the application of power supply, then no selected channel can be determined. Thus, a control circuit 6 makes H only for the output X5 of the channel 5 even if the outputs X1-X5 are all at L at the application of power supply, allowing to prevent the coincidence of the outputs X1-X5of the FFs.
