In the measuring device 1, a simple operation is performed by a tap operation, and various settings and detailed operations of the measuring device 1 are performed by an external device via wireless communication. With this configuration, the measuring device 1 eliminates the need for buttons and switches for operation. The signal from the acceleration sensor can also be used in the body motion noise suppression process that is superimposed on the pulse wave signal when detecting biological information.

  The measuring device 1 is a device intended to measure biological information in the daily life of the wearer not only when the wearer exercises such as walking or running, but always wearing it. Therefore, even if the measuring device 1 is worn for a long time, the burden on the wearer (for example, the weight, size, shape of the device, discomfort caused by the tightening force) is small, and the posture of the wearer It is required that biological information can be measured in a stable state regardless of the operation. The measuring device 1 eliminates the monitor unit (display), buttons, and switches, thereby enabling a reduction in size and weight and a longer battery life as compared with general measuring devices. Further, when the wearer measures the pulse rate during exercise, body motion noise caused by exercise is superimposed on the pulse wave detected by the detection unit. In order to extract only the pulse wave component from the pulse wave signal on which the body motion noise is superimposed, an acceleration signal output from the acceleration sensor of the tap operation sensor unit may be used. As a result, the acceleration sensor for detecting the tap operation and the acceleration sensor for extracting the pulse wave component can be shared by one acceleration sensor, so that cost reduction, size reduction, and battery life extension can be realized.

As a material of the annular portion 31 and the sandwiching portion 32, stainless steel is mainly used as a preferred example. The material is not limited to this, and may be any material that has good corrosion resistance, satisfies the durability, and is lightweight. For example, titanium may be used. The annular portion 31 is formed with higher rigidity than the sandwiching portion 32. The sandwiching portion 32 has elasticity, and is formed to have higher elasticity and lower rigidity than the annular portion 31 at least in a contact portion with the annular portion 31. In this embodiment, it has the elastic deformation part 35 which contacts the cyclic | annular part 31 and elastically deforms when the 2nd band part 24 penetrated by the cyclic | annular part 31 is inserted | pinched by the clamping part 32. FIG.
The annular portion 31 and the sandwiching portion 32 of the fixing portion 30 may be made of resin instead of metal as long as the durability is satisfied and the above-described rigidity level is the same. Thereby, since the unity feeling of the band 20 and the fixing | fixed part 30 increases, it looks good.

  After inserting the second band part 24 through the opening of the annular part 31, the tip part 25 side of the second band part 24 is pulled out from the annular part 31, and when the mounting state of the band 20 is in a good tightening state, As shown in FIG. 5, the sandwiching portion 32 is rotated to sandwich and fix the second band portion 24 inserted through the annular portion 31.

The sandwiching portion 32 is held with respect to the portion 31.

  As described above, the distal end portion 25 of the second band portion 24 fixed at a desired position by the fixing portion 30 is held by the first band portion 22 by the locking portion 33. The locking portion 33 is formed of an elastic material such as an elastomer, for example, and is held in a state of being fitted into the first band portion 22 due to the elasticity of the locking portion 33. Thereby, the front end 25 side of the second band portion 24 remaining from the fixing portion 30 in the mounted state of the band 20 can be prevented from causing troubles such as getting in contact with clothes or surrounding objects and getting in the way. The appearance of the mounting state of the case portion 10 which is the device body of the measuring device 1 can be improved.

Here, since the 1st band part 22 of this embodiment has the recessed part 26 matched with the shape of the latching | locking part 33 in the both ends along the extending direction of the 1st band part 22, attachment of the band 20 is carried out. In this state, when the distal end 25 side of the second band portion 24 remaining from the fixing portion 30 is held by the locking portion 33, the portion of the locking portion 33 that protrudes from the first band portion 22 can be kept small. . Thereby, while the locking part 33 becomes difficult to become obstructive in the mounting state of the band 20, the appearance can be improved.
In addition, the recessed part 26 provided in the both ends along the extending | stretching direction of the 1st band part 22 may be a notch matched with the shape of the latching | locking part 33. FIG.

  FIG. 6 is an explanatory view showing an overlapping state of the first band portion 22 and the second band portion 24 in the mounting state of the band 20, and shows the mounting state of the band 20 by the fixing portion 30. As shown in FIG. 6, in a state where the band 20 is worn on the body of a wearer (user), for example, a wrist, by the fixing portion 30, the width of the first band portion 22 is d1, and the width of the second band portion 24 is d2. In this case, at least in the region where the first band portion 22 and the second band portion 24 overlap, the relationship of d1 ≦ d2 is established. Thereby, in the mounting state of the band 20 by the fixing unit 30, the first band unit 22 can be hidden and hidden under the second band unit 24 located in front of the wearer's line of sight. A band having a good appearance can be obtained.
