Photoelectric sphygmograph measurement device

A photoelectric sphygmograph measurement device comprising:

• a light emitting part configured to emit light pulses;
• a light receiving part configured to have a light receiving element that receives the light pulses emitted by the light emitting part and to produce an output signal corresponding to the light pulses received by the light receiving element;
• and
• a control part configured to drive the light emitting part to emit the light pulses and perform a pulse wave measurement on the basis of the output signal of the light receiving part,
• the control part driving the light emitting part so that a charge accumulated in the light emitting element converges on a predetermined amount in a case where the charge accumulated in the light receiving element decreases to the predetermined amount or less during a time when driving of the light emitting part is stopped and/or in a case where the light receiving element changes to a first state in which the light receiving element is capable of receiving the light pulses from a second state in which the light receiving element is not capable of receiving the light pulses.
