Abstract
A pulse wave measuring device includes: a connector that is disposed on a main unit; an external sensor that includes an external light-emitting module radiating light to a human body to be measured and an external light-receiving module receiving at least one of reflected light and transmitted light originating from the external light-emitting module and the human body so as to measure a pulse wave; an first controller that switches the external light-emitting module ON and OFF; an second controller that switches the external light-receiving module ON and OFF; and an external sensor connection determination section that determines a connection between the external sensor and the connector in accordance with a transient response of the external light-receiving module, wherein, after the external sensor connection determination section determines that the external sensor is connected to the connector, a measurement of the pulse wave by using the external sensor is started.

5. A pulse wave measuring device comprising:
-
an external sensor that includes an external light-emitting module emitting light to a human body to be measured and an external light-receiving module receiving at least one of reflected light and transmitted light originating from the external light-emitting module so as to measure a pulse wave; a first controller that controls the external light-emitting module; a second controller that controls the external light-receiving module; and the external sensor attachment determination section that determines the external sensor is properly put on the human body according to whether or not an output from the external light-receiving module produced by activation of the external light-receiving module remains continually smaller or larger than a given threshold level for a given period of time or longer than the given period of time. - View Dependent Claims (6)
