ELECTRIC TOOTHBRUSH

摘要

An electric toothbrush comprising: an electric toothbrush body provided with the drive source for the brush; an attitude sensor for detecting the attitude of the electric toothbrush body; and a control means for selecting the operation mode of the electric toothbrush according to the result of comparison between a previously determined threshold value and an attitude value (S) which is a value calculated from the output from the attitude sensor. The threshold value (A) used to determine the switching from an operation mode (1) to an operation mode (2) and the threshold value (A-a) used to determine the switching from the operation mode (2) to the operation mode (1) are set to different values.
