PURPOSE:To give a warm feeling and familiarity to a person to be photographed by so constituting a titled device that melodies are produced during self-timer photographing. CONSTITUTION:When a user operates a self-timer switch SW1 and sets switches SW2-SW4 by depressing a release button, both inputs of an AND circuit 11 goes to a logic 1, thereby setting an FF13. Then, the Q output of the FF13 goes to a logic 1, and a decoder 14 generates the signal corresponding to a self-timer photographing mode to its outputs CC1, CC2. As a result, the output of the output CC1 goes to a logic 1 and melody sounds are produced from a melody producing circuit 25. On the other hand, the output of the circuit 11 sets an FF22 via a NOR circuit 23, and the Q output thereof initially sets a counter 18. When the outputs Q24, Q26 of the counter 18 go both to a logic 1 after a prescribed time, an FF15 is set, and a decoder 14 is set in shutter start mode. Then, the output CC2 goes to a logic 1, and a shutter start circuit 28 operates. |
