Abstract

A pedometer (100A) has a sensor unit (150) fixedly placed so as to detect a body motion in the direction of a predetermined detection axis and also has a body casing where the sensor unit (150) is received. The detection axis of the sensor unit (150) is placed with an inclination angle relative to an attachment surface (122) of the body casing which surface is attached to a human body. The inclination angle is within a detectable angle range of the sensor unit (150). A reduction in measurement accuracy caused by variation in conditions of attachment of the pedometer on users, which variation occurs due to the body shapes of a users, is prevented, and the pedometer is inexpensive and small sized.

Description

technical field [0001] The invention relates to a body motion detection device which is worn on the body to detect the body motion, in particular to a pedometer capable of counting the number of steps by detecting the body motion. Background technique [0002] Hitherto, there has been known a pedometer that is worn on the body to detect body motion, and measures the number of steps based on the detected body motion information. In this pedometer, a body motion detection unit for detecting body motion is provided inside the main body case. Various structures are used as the body motion detection unit, and one of the known structures is to use a sensor unit composed of a plate-shaped member having a cantilever beam structure and a piezoelectric element attached to the plate-shaped member as the body motion detection unit. . In the body motion detection unit having such a structure, the plate-shaped member bends with the body motion to deform the piezoelectric element, and de...
