<p>PURPOSE:To reduce an unpleasant feeling or a feeling of uneasiness due to the continuous ringing of an error sound by providing an information processor with a ringing time measuring timer and a sound adjusting device. CONSTITUTION:When an error is generated in the information processor, an error signal 15 is sent from the information processor body or the like to an acoustic output signal generating means 14. The means 14 outputs an acoustic output signal 12 and a speaker ringing signal 2 is outputted from a driver 1 receiving the signal 12. The signal 2 is amplified through an amplifier 3 to ring a speaker 4. At this point of time, a ringing time measuring signal 5 is outputted independently of the signal 2 and inputted to a timer 6. The timer 6 measures time T inputting the signal 5 and outputs a volume changing signal 16 after the lapse of the time T. The volume adjusting device 7 is driven by the signal 16 and sound volume is reduced to ease operator's or shopping customer's unpleasant feeling.</p> |
