摘要：
PROBLEM TO BE SOLVED: To provide an electric toothbrush and an operation method for such an electric toothbrush capable of accurately detecting plaque, etc. on a site now being brushed with the toothbrush in real time.SOLUTION: The electric toothbrush includes a control part 50 performing a first drive and a second drive for a vibration unit on which a plurality of brushes 22, a light emitting part 23, and a light receiving part 24 are arranged: the first drive causing the vibration part to vibrate in a first direction which is a pressing direction of the plurality of brushes 22 and the second drive causing the vibration unit to vibrate in a second direction different from the first direction. The control part 50 performs control which causes the light emitting part 23 to emit light at least while the first drive is being performed. The control part also causes a plaque detection process to be performed using a signal corresponding to the light received by the light receiving part 24 while the first drive is being performed.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】歯磨きしている部位の歯垢等を歯磨き中にリアルタイムに精度よく検知することのできる電動歯ブラシ及びその作動方法を提供する。【解決手段】電動歯ブラシは、複数のブラシ22、光出射部23、及び受光部24が設けられた振動部を複数のブラシ22の押し当て方向である第一の方向に振動させる第一の駆動と、振動部を第一の方向とは異なる第二の方向に振動させる第二の駆動とを行う制御部50を備える。制御部50は、少なくとも、第一の駆動が行われている間に光出射部23から光を出射させる制御を行い、第一の駆動が行われている間に受光部24で受光された光に応じた信号を用いて歯垢検出処理を行う。【選択図】図2
