  Since the measurement unit 50 and the display unit 114 have been described above, description thereof will be omitted.

  Next, the band 20 of the pulse measuring device 1 will be described with reference to FIGS.

  FIG. 5A is a plan view (corresponding to the outer peripheral side at the time of mounting) when the band 20 is unfolded, and a rear view (corresponding to the inner peripheral side at the time of mounting) opposite to (A). As shown in FIG. 5B, the band 20 is originally an elongated band-like body extending in the longitudinal direction on the right side of FIG. The band 20 that restricts the main body 10 from being separated from the measurement site 3 is flexible so that it can freely bend and surround the measurement site 3, and stretchable at least in the longitudinal direction. And, it is comprised from the dough which has. The fabric of the band 20 is made of a material such as polyester, polyurethane, polyamide-based synthetic fiber (nylon: registered trademark), or rubber. The band 20 is composed of a single fabric or a laminate in which a plurality of fabrics are laminated.

  The band 20 includes a main body holding part 23 that holds the main body 10 so that the main body 10 is not separated from the measured part 3, and a surrounding part 25 that is connected to the right side from the main body holding part 23 and surrounds the measured part 3.

  An opening 24 is formed in the main body holding part 23. The opening 24 is formed at a position corresponding to the display unit 114 and functions as a window unit that allows the display unit 114 to be seen from the outside of the main body 10 so as to receive the head 13 and the neck 12 of the main body 10. Open to As described above, since the head portion 13 and the neck portion 12 of the main body 10 have a substantially rectangular shape with rounded corner portions, the opening 24 of the band 20 also corresponds to the rectangular shape of the main body 10. With respect to the surface direction of the band 20, the corner portion has a substantially rectangular shape with roundness. The opening size of the opening 24 is configured to substantially match the outer size of the constricted neck 12. In the pulse measuring device 1 in which the main body 10 is attached to the band 20, the outer shape of the neck 12 and the substantially rectangular opening 24 are engaged. Therefore, the part which protrudes toward the opposite side to the lower surface 15 from the upper surface of the base part 11 of the main body 10, that is, the four side surface parts 12a, 12b, 12c and 12d of the neck part 12 of the main body 10 (see FIG. 2A). )) And the four opening sides 24a, 24b, 24c, and 24d constituting the substantially rectangular opening 24 of the band 20, the main body 10 and the band 20 are relatively relative to each other in the plane direction along the lower surface 15 of the main body 10. A restricting portion that restricts movement is formed.

  A long female side surface fastener 26 extending in the longitudinal direction and a short male side surface fastener 28 extending in the longitudinal direction are respectively attached to the winding portion 25 and the upper surface 22a of the terminal portion 27 located on the right side of the winding portion 25. . The female side fastener 26 and the male side fastener 28 form a hook-and-loop fastener engaging structure that is detachably engaged with each other. In addition, you may make the attachment place and length of the female side fastener 26 and the male side fastener 28 reverse to what was shown to FIG. 5 (A). Further, the female side fastener 26 and the male side fastener 28 may be attached to the lower surface 22 b side of the winding portion 25.

  A buckle member 30 refracted into a substantially rectangular shape is attached to the left end portion 29 of the main body holding portion 23. Between the left end portion 29 and the buckle member 30, an attachment hole 32 having a gap through which the winding portion 25 can be inserted is formed.

  As shown in FIGS. 1, 3, and 4, in the normal usage pattern of the pulse measuring device 1, the neck portion 12 of the main body 10 is fitted into the opening portion 24 of the band 20. Since the size of the base portion 11 of the main body 10 is larger than the size of the neck portion 12 of the main body 10, the base portion 11 of the main body 10 is supported by the peripheral portion of the opening 24 of the band 20. Therefore, the fitting support structure prevents the main body 10 from inadvertently falling off the band 20.

  With reference to FIG. 4, a method of mounting the pulse measuring device 1 on the measurement site 3 will be described.

  In the pulse measuring device 1 wrapped around the outer peripheral surface of the measurement site 3, the inner periphery of the main body 10 and the band 20 with the end portion 27 of the band 20 inserted into the attachment hole 32 formed in the buckle member 30. The length of the band 20 is adjusted so that the surface length is longer than the outer peripheral surface length of the measurement site 3. At this time, the end portion 27 of the band 20 is inserted from the inside of the buckle member 30 toward the outside, and the inserted end portion 27 is folded back by the buckle member 30. Since the female side fastener 26 faces in the direction opposite to the measured site 3 and the male side fastener 28 faces in the measured site 3, the female side fastener 26 and the male side fastener 28 are mutually connected. It is a face-to-face arrangement.

  After positioning the measurement unit 50 with respect to the measurement site 3, the band 20 can be tightened by pulling out the end portion 27 of the band 20. The tightening degree of the band 20 can be adjusted according to the amount by which the end portion 27 is pulled out. Measurement of the measurement site 3 is performed by engaging the male side surface fastener 28 with the female side surface fastener 26 after appropriately adjusting the tightening degree of the band 20 so that the lower surface 15 of the main body 10 is not separated from the measurement site 3. Accurate positioning of the part 50 and regulation so that the lower surface 15 of the main body 10 is not separated from the measurement site 3 are achieved. When the measurement of the biological information is completed, the engagement between the male side surface fastener 28 and the female side surface fastener 26 is released, so that the tightening of the band 20 is loosened, and the pulse measuring device 1 is removed from the measurement site 3. Can be removed.

  As described in the section “Problems to be Solved by the Invention”, the pulse rate display device according to the prior art has insufficient adhesion to the measurement site. For this reason, in the pulse rate display device according to the prior art, when the arm is shaken greatly or quickly during jogging or other exercise, the sensor is likely to be displaced with respect to the measurement site. There was a risk of noise. In addition, if the pulse rate display device is worn on a wrist or the like during an exercise such as jogging, the pulse rate display device may be soiled by sweat, fat or dust.

  On the other hand, in this pulse measuring device 1, the neck portion that is spaced apart from the lower surface 15 in contact with the measurement site 3 in the upward direction (that is, the band longitudinal orthogonal direction) by the upward distance (that is, the thickness of the base portion 11). 12, a band 20 is attached. In the configuration in which the band 20 is attached to the neck portion 12 of the main body 10, when the band 20 attached to the main body 10 is wrapped around the measurement site 3 as shown in FIG. 3), tension F is applied. Accordingly, an orthogonal component force Fv that is perpendicular to the contact surface with the measurement site 3 and goes toward the center of the measurement site 3 according to the upward distance of the base 11 (that is, the thickness of the base 11). Act. The orthogonal component force Fv acts as an adhesion force that presses the main body 10 toward the measurement site 3 to bring the main body 10 into close contact with the measurement site 3. Therefore, in this pulse measurement device 1, the body component 10 having the measurement unit 50 is in close contact with the measurement site 3 with sufficient adhesion by the action of the component force Fv in the orthogonal direction toward the center of the measurement site 3. Therefore, it is possible to accurately measure the biological information of the measurement subject. Further, when the pulse rate display device 1 is soiled by sweat or the like, the band 20 can be removed from the main body 10 and the band 20 can be used for washing.

  Moreover, in this pulse measuring device 1, since the display part 114 is arrange | positioned in the upper surface 16 side, ie, the head 13, the user (a to-be-measured person is included) displays the display content displayed on the display part 114. It can be seen from the outside of the main body 10.

  Next, a modification of the band 20 shown in FIG. 5 will be described with reference to FIGS. 6, 7 and 8 show a first modification, a second modification and a third modification of the band 20 shown in FIG. 5, respectively. The basic configuration of the bands 20A, 20B, and 20C according to each modification is the same as that of the band 20 shown in FIG. 5, and will be described below with a focus on differences from the band 20 shown in FIG. .

  6A, 6B, and 6C are respectively a plan view when the band 20A according to the first modification is developed (corresponding to the outer peripheral side at the time of mounting), and the opposite side of FIG. FIG. 4 is a rear view (corresponding to the inner peripheral side at the time of mounting), and a partial cross-sectional view taken along line AA of the band 20A shown in FIG. The band 20A according to the first modification is characterized in that a reinforcing sheet 40 for reinforcing the band 20A is attached to the main body holding portion 23 of the band 20A. A reinforcing sheet 40 configured to surround the opening 24 of the main body holding portion 23 is attached to a peripheral portion of the opening 24 of the band 20A by an adhering method such as adhesion, sewing, and heat fusion. The reinforcing sheet 40 has a substantially rectangular shape corresponding to the substantially rectangular opening 24. The reinforcing sheet 40 is made of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyamide synthetic fiber (nylon: registered trademark), and polyurethane.
