Kind Code:
B2
Abstract:
A pulse wave detecting apparatus having a housing (18) which is placed on a body surface (10) of a subject such that the housing is aligned with an artery (12) of the subject via the body surface, a pulse wave sensor (20) accommodated in the housing, the pulse wave sensor being pressed against the body surface for detecting pulse wave produced from the artery, and a pressing device (22) supported by the housing, the pressing means pressing the pulse wave sensor against the body surface with an optimum pressing force, the optimum pressing force being determined based on pulse wave signal (SM) generated by the pulse wave sensor while the pressing force of the pressing means is varied, the apparatus includinga a detecting device (24, 48, 60, 68) for detecting whether or not the housing (18) has been placed on the body surface (10) of the subject.
