First Claim
Patent Images
1. A pulse wave sensor device comprising:
- a device body having a contoured shape grippable by a hand of a user;
a measurement sensor having;
a light emitter configured to emit light to a measurement location on the hand when the user grips the device body, anda light receiver configured to detect light reflected by the measurement location; and
a protruding member extending from the device body that contacts a blood-flow blockage reducing location of the hand when the user grips the device body, such that the protruding member reduces blockage of blood flow in the hand at the measurement location.

Abstract
A light emitter and a light receiver are provided at a side surface of a lever. When a user grips the lever with his hand, the light emitter and the light receiver are positioned close to bases of the middle finger, a ring finger, and a little finger, as a measurement portion of a palm. A blood-flow blockage reducing component protrudes to contact a portion between the index finger and the middle finger, and a thumb, as a contact portion of the palm.
