PROBLEM TO BE SOLVED: To provide an electronic device equipped with an impact detector for a motor capable of detecting impact more quickly and precisely.SOLUTION: An electronic device 1 includes an operation unit 5 capable of generating a signal representing a physical quantity. A motor 4 includes a rotor in a magnetic circuit and two terminals, positive and negative. The operation unit 5 controls a motor 4 via the two terminals and includes at least one impact detection circuit connected between the operation unit 5 and the motor terminals for detecting external impact acted on the motor 4. The operation unit 5 detects a rotation direction of the rotor by analyzing an induced voltage detected by the detection circuit after impact using an algorithm to transmit a blocking pulse having reverse polarity of the induced voltage.SELECTED DRAWING: Figure 1 【課題】より高速かつ正確に衝撃の検出を可能とする、モータ用の衝撃検出装置を設けた電子装置を提供する。【解決手段】物理量を表す信号を生成することが可能な演算ユニット５を備えた電子装置１であって、モータ４は、磁気回路内のロータと、正と負の２つの端子を介して演算ユニット５はモータ４を制御し、モータ４に作用した外部衝撃を検出するために、演算ユニット５とモータ端子との間に接続された少なくとも１つの衝撃検出回路を備える。演算ユニット５は、アルゴリズムを用いて、衝撃の後に、検出回路で検出された誘起電圧を分析することによりロータの回転方向を検出し、誘起電圧の極性とは逆極性のブロッキングパルスを伝送させる。【選択図】図１
