The sound volume controlling apparatus comprises UP and DOWN keys (42, 43) depressed manually; a time period detecting circuit (39h, 39d) for detecting time period from when the duration of UP or DOWN key depression reaches a predetermined value (e.g. 0.5 sec) to when the continuous key depression ends; a sound volume value deciding circuit (39e, 39f, 37a) for changing the sound volume value during the time duration detected by the time period detecting circuit; and sound volume changing circuit (37b, 45) for changing the sound volume in accordance with the value decided by the sound volume value deciding circuit. Since the sound volume is changed only after the key is kept depressed for a predetermined time period (e.g. 0.5 sec), it is possible to prevent the sound volume from being changed erroneously due to a short time touch to the keys.
