Claims

[Claims for Utility Model Registration] In an operation detection circuit that detects the energization state of a circuit including a drive element that becomes conductive when a drive signal is applied to an input terminal and enables energization of a driven element, A detection unit that outputs a continuity detection signal at one of two levels depending on whether the element is conductive or not, and compares this continuity detection signal with the above drive signal and outputs an operation detection signal only when they match. a control section that generates synchronized first and second check pulses immediately after the leading edge and immediately after the trailing edge of the drive signal, and applies these as detection timing pulses to the comparing section. A motion detection circuit characterized by comprising:
