Patent number: 10016041Abstract: A hair removal tool is equipped with: a drive unit for driving a blade; a load detection unit for detecting the size of the load on the drive unit; and a control unit for changing the drive mode of the drive unit between a first drive mode for driving the drive unit at a first drive speed, a second drive mode for driving the drive unit at a second drive speed which is faster than the first drive speed, and a transition mode for driving the drive unit at a transition speed which is faster than the second drive speed. A first interval is set as the interval from when the drive mode is changed from the first drive mode to the transition mode until when the drive mode is changed from the transition mode to the second drive mode. A second interval is set as the interval from when the drive mode is changed from the transition mode to the second drive mode until when the drive mode is changed from the second drive mode to the first drive mode. The first interval is shorter than the second interval.Type: GrantFiled: January 23, 2014Date of Patent: July 10, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Takafumi Ohba, Koji Asakawa, Masanobu Yamasaki, Yoichi Takaoka
