ABSTRACT:
The invention provides a wrist-worn pulse wave measuring device capable of outputting data measured by the wrist-worn pulse wave measuring device to an external data processing device without using a large device body. In the pulse information processing apparatus, a connector piece of a sensor unit is mounted to a connector of a wrist-worn pulse wave measuring device when measuring the pulse. A data transmission connector piece is mounted to the connector of the pulse wave measuring device when transmitting data with a data processor. Whether the operating mode is the pulse measurement mode or the data transmission mode is determined by a signal discriminator which discriminates the signal input from the connector of the pulse wave measuring device.
