CORRECTION APPARATUS OF TOUCH SWITCH, AND CORRECTION METHOD OF TOUCH SWITCH

PROBLEM TO BE SOLVED: To provide a correction apparatus of touch switch, along with a correction method of a touch switch, wherein even if a discharge time of a touch switch is varied owing to disc tray movement or motor driving, contact with a human body is always detected with reliability for sufficient practical use. SOLUTION: A touch switch (17) which determines whether an operation has been performed based on a difference in discharge time between a case in contact with a human body and a case not in contact with a human body, is provided with control means (36 and 36d). The control means makes control so that, when a corrective process is periodically applied so that a difference between a discharge time at contact with a human body and a discharge time is a threshold value for discriminating contact with a human body is always constant, the corrective process is executed when driving a motor (21) is stopped and no process is executed while the motor (21) is driven.
