Description

  The present invention relates to a band and a biological information measuring apparatus including the band.

  In recent years, many wristwatch-type activity meters (biological information measuring devices) have been commercialized by various companies due to improvements in sensing technology. In addition, a band used for fixing such an activity meter, a watch (clock), etc., for example, to the arm of a subject has been invented. As such a conventional technique, for example, a technique described in Patent Document 1 is disclosed.

  In the invention described in Patent Document 1, as shown in FIG. 1 of the same document, the band is stretchable and has a shape that can easily cope with a change in arm diameter. Specifically, since the shape is easy to extend in the longitudinal direction of the band, the sensor unit provided on the back surface of the activity meter can be brought into close contact with the skin surface with a predetermined pressure.

  However, in recent years, it is necessary to sense biological information not only in a conventional activity meter (for example, a pulse meter) but also in sports equipment used for intense movement such as a running watch equipped with a GPS (Global Positioning System). It is growing. In addition, even with the use of an activity meter, there are models that wear and measure all day long, and the same situation as sports equipment can occur. When the band disclosed in Patent Document 1 is used in a device used for such intense movement, a large gravitational acceleration is applied to the device main body due to a strong arm swing or the like, and the expansion / contraction part provided in the band is extended in the extension direction. Forces in different directions may be applied. As a result, the device body shakes, twists, or tilts according to the movement of the arm. In this case, the sensor unit disposed on the back cover of the device main body cannot be kept in close contact with the skin surface, which may cause erroneous detection of sensor signals.

  Such a stretchable part 21 (22) can be extended along the first direction DR1 by this bellows structure when a tensile force is applied in the first direction DR1, but the extension direction It is difficult to move in a direction different from the direction (second direction DR2). Therefore, the stretchable part 21 (22) extends in the direction of extension (first direction DR1) of the stretchable part 21 (22) of the band part 31 (32), but in a direction (second direction) different from the stretched direction. It is possible to restrict movement in the direction DR2).
