を特徴とする音量調整装置。[Scope of Claim for Utility Model Registration] A volume control unit that controls the volume based on the volume control data, including a volume control data storage unit that stores volume control data that is changed according to the operation of the operation unit and retains it even after the power is turned off. A volume adjustment device having: a prescribed volume data storage section that stores predetermined prescribed volume data; and a volume adjustment device that determines the magnitude of the elapsed time from when the power is turned off to when the power is turned on and a predetermined reference time. and a power-off elapsed time determining section, wherein the volume control section stores information in the volume control data storage section when the power-off elapsed time determining section determines that the elapsed time is smaller than the reference time when the power is turned on. The volume is controlled based on the stored volume control data, and conversely, when the power off elapsed time determining unit determines that the elapsed time is greater than the reference time, the volume is controlled based on the specified volume data read from the specified volume data storage unit. A volume adjustment device characterized in that it is configured to perform control.
