<p>PURPOSE:To prevent malfunction by putting a sounding body which produces sounds when the output signal of a remote controller is received into the state being ready to operate. CONSTITUTION:When a recorder body 11 receives the constant speed system signal of a remote control unit 12, a sounding body 26 is made ready to operate via a decoder part 20. An oscillating part 23 is oscillated by the single shot pulse of the part 20, and said output signal forces said piezoelectric buzzer 26 to produce a single shot sound. A high level signal is supplied to an intermittent signal part 29 by the high speed system signal of the remote controller for the same time as the operation time of a mechanism part 22 separately from the driving signal from a logic part 21. The oscillating part 23 is oscillated intermittently by the signal of the part 29, and intermittent sounds are produced from the buzzer 26. The intermittent sounds are produced during the operation of the high speed system. Generation of said single sound and intermittent sounds are inhibited by an inhibition circuit 32 while an electric power source turns on and off.</p> |
