PURPOSE:To constitute a titled clock so that a holder can select freely, displaying the priority order of an output sound, by constituting an electronic clock which is capable of outputting plural output sounds, by containing a sound output priority order indicator and a priority order controlling circuit. CONSTITUTION:A signal of each state sound to be outputted from the first, the second and the third sound output state generating circuits 1, 2 and 3 is sent to a priority order controlling circuit 4. A signal of a priority order selected from a switch input controlling circuit 11 for selecting and inputting to which sound the priority should be given is inputted to priority order flags 7, 8 and 9, an output from the flag is sent to a priority order indicator 10 and the priority order of an output sound is displayed. In accordance with a signal from the flag, in case when states to be outputted of the first sound, the second sound and the third sound are superposed, the priority order controlling circuit 4 sends out a sond output state signal whose priority order is the highest to a sound output generating circuit 5. |
