PROBLEM TO BE SOLVED: To provide a hand-held device and a vibration cancel method which improve a tremor inhibition device.SOLUTION: A hand-held device comprises: a base which includes a handle and catches a vibration operation； a grip element combined with the base to detachably connect the hand-held device with an object； at least one inertial sensor which detects the acceleration of the vibration operation and generates an acceleration signal； a processing unit which determines that a cancel determination is to be generated in accordance with the acceleration signal； and an actuator which controls the operation of the grip element in accordance with the cancel determination and weakens the acceleration. The hand-held device 10 does not apply a comparatively large force to user's affected limbs, which prevents a user from feeling a discomfort, a pain, or other troubles. The hand-held device 10 detects the acceleration of a vibration operation VR and weakens the acceleration in response to it, so that a tremor does not trouble the user. Furthermore, a shape memory alloy (SMA) is not used for the hand-held device 10, so that the user does not need to worry about a failure due to a metal fatigue of the hand-held device 10.SELECTED DRAWING: Figure 1【課題】振戦抑制装置を改良する手持ち式機器および振動取消方法を提供する。【解決手段】手持ち式機器は、持ち手を含み、振動動作を受け止めるベースと、手持ち式機器を物体に着脱可能に接続するためにベースに連結されるグリップ要素と、振動動作の加速度を検知して加速度信号を生成する少なくとも１つの慣性センサと、加速度信号に従い取消決定を生成することを判断する処理ユニットと、取消決定に従いグリップ要素の動作を制御し、加速度を弱める少なくとも１つのアクチュエータとを備える。手持ち式機器１０は、ユーザの罹患した四肢に比較的大きな力を付与せず、ユーザは不快感や痛みに悩まされ無い。手持ち式機器１０は、振動動作ＶＲの加速度を検知し、それに従い加速度を弱め、振戦に悩まされない。さらに、形状記憶合金（ＳＭＡ）が手持ち式機器１０に使用されず、手持ち式機器１０の金属疲労による故障をユーザが心配する必要が無い。【選択図】図１
