Pulse wave detecting device, biological information measuring device, pulse wave detecting device control method, and pulse wave detecting device control program

摘要

The present invention provides a pulse wave detecting device capable of improving pulse wave detection accuracy by flexibly changing a pressing state, toward a body surface, of a sensor section pressed against the body surface for use, a vital information measuring device, a method for controlling a pulse wave detecting device, and a control program for a pulse wave detecting device. A sensor section 6 is rotatable about a first axis X and is rotatable about a second axis Y. A control unit 12 determines a rotation angle about the first axis X (an optimal pitch angle), and determines a rotation angle about the second axis Y (an optimal roll angle) in a state where a pitch angle of the sensor section 6 is controlled to the optimal pitch angle. Then, in a state where the sensor section 6 is controlled to the optimal roll angle and the optimal pitch angle, the sensor section 6 is pressed against the body surface, and a pulse wave is detected in this state based on pressure signals detected by pressure detecting elements 6a and 7a, and vital information is calculated based on the detected pulse wave.
