A motion assist device includes a drive mechanism that applies a force to the body of a user through the intermediary of a first orthosis and a second orthosis, posture detectors that detect the posture of the user, and a control unit that controls the drive mechanism. A transmission mechanism of the drive mechanism is configured to be switchable between a transmission mode, in which a driving force based on a spring is transmitted to move a joint into a predetermined state, and a non-transmission mode, in which a joint can be freely moved without transmitting the driving force that has been accumulated. The control unit automatically switches the transmission mechanism to the non-transmission mode when a predetermined trigger event is recognized based on the posture of the user.

Motion assist device

A light emission reference signal, the timing of which is adjusted by a first delay time control circuit, is input as a timing adjustment signal to a light emitter driver. The light emission reference signal, which is delayed by a second delay time control circuit, is output as an offset signal. The offset signal and a light emission timing signal from the light emitter driver are input to a timing correction phase comparator, and a phase comparison result is output from the timing correction phase comparator. The phase comparison result is input to a timing correction control logic circuit, and a delay adjusting signal based on the phase comparison result is output from the timing correction control logic circuit. The delay adjusting signal is input to the first delay time control circuit, whereby the timing of the light emission reference signal is adjusted.
