  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Outline of this embodiment A configuration example of the biological information detecting apparatus 100 of this embodiment will be described with reference to FIG. 1 (A) and FIG. 1 (B). 1A shows a perspective view of the upper surface (front surface) of the biological information detection device 100, and FIG. 1B shows a perspective view of the lower surface (back surface) of the biological information detection device 100.

  The biological information detection apparatus 100 is attached to a subject and includes a case unit 30 provided with a sensor unit 90 that detects biological information of the subject, a band unit 11 (12) attached to the case unit 30, and a regulating unit 210 ( 220). And the band part 11 (12) has the expansion | extension part 21 (22) extended | stretched along the 1st direction which is a longitudinal direction of the band part 11 (12). In the example of FIGS. 1A and 1B, the restricting portion 210 (220) shields a part of the extending portion 21 (22) so that it cannot be viewed directly from the outside. (22) is indicated by a dotted line.

  And the control part 210 (220) is provided in the position corresponding to the expansion | extension part 21 (22), and made the direction which goes to a 2nd side surface from the 1st side surface of the expansion | extension part 21 (22) into the 2nd direction. In this case (when the direction intersecting the first direction is the second direction), the movement of the extending portion 21 (22) in the second direction is restricted.

  Here, the position corresponding to the extension part 21 (22) is, for example, as shown in FIGS. 1A and 1B, the extension part 21 (22) at the time of non-extension in the first direction. (Omitted) The same position. That is, when the shape of the restricting portion 210 (220) is the shape as shown in FIGS. 1A and 1B, the restricting portion 210 (220) is not extended to the extended portion 21 ( 22) is provided so as to cover (shield).

  Further, the second direction is a direction from the first side surface of the extending portion 21 (22) toward the second side surface, and is a direction different from the first direction. In the example of FIG. 4A described later, the first direction is DR1 and the second direction is DR2. In the example of FIG. 4A described later, the second direction DR2 is a direction orthogonal to the first direction DR1, but the present embodiment is not limited to this, and the second direction is the first direction. Any direction that intersects the direction of

  The biological information detection apparatus 100 shown in FIGS. 1A and 1B will be described in more detail. The biological information detection apparatus 100 includes a first band unit 11, a second band unit 12, It includes a case portion 30, a fixing portion (free leather, fixed leather) 40, a connecting portion (beautiful tablet) 50, a display portion 70, an operation portion 80, and a sensor portion 90. However, the biological information detection apparatus 100 is not limited to the configuration shown in FIGS. 1A and 1B, and some of these components may be omitted or other components may be added. Various modifications are possible.

  The first band portion 11 is attached to one end of the case portion 30, and the second band portion 12 is attached to the other end of the case portion 30. Further, the first band portion 11 has a first extension portion 21 that can be extended, and the second band portion 12 has a second extension portion 22 that can be extended.

  The connecting portion (beautiful tablet) 50 connects the first band portion 11 and the second band portion 12. The fixing part (free leather, constant leather) 40 fixes the first band part 11 along the second band part 12 in a state where the first band part 11 and the second band part 12 are connected. .

  The display unit 70 displays various information. The operation unit 80 receives user operations. The sensor unit 90 is provided on the back cover (back surface) of the case unit and detects biological information of the subject while being pressed against the subject.

  On the other hand, Patent Document 1 described above exemplifies a biological information detection apparatus as shown in FIGS. 2 (A) and 2 (B). Unlike the biological information detection device 100 shown in FIGS. 1A and 1B, the biological information detection device shown in FIGS. 2A and 2B has a regulating unit 210 (220). Not.

  As described above, in the biological information detecting device having a band as shown in FIGS. 2A and 2B, a large gravitational acceleration is applied to the device main body due to a strong arm swing or the like, and the extending portion provided in the band. A force in a direction different from the extension direction may act on 21 (22). As a result, the device body shakes, twists, or tilts according to the movement of the arm.

  For example, an example thereof is shown in FIGS. FIG. 3A shows the band BD and the subject surface SF when not stretched. From this state, when the band BD extends in the extension direction DR1 (first direction described later) of the extension part, the state shown in FIG. 3B is obtained. In the state of FIG. 3B, as in FIG. 3A, since the sensor unit SE is in close contact with the subject surface SF, the sensor signal can be normally acquired. Therefore, there is no problem.

  On the other hand, as shown in FIG. 3C, when a force is applied in a direction DR2 different from the extension direction DR1 of the extension part, the sensor part SE is lifted as indicated by P1 from the subject surface SF. . Therefore, the sensor unit SE cannot normally acquire the sensor signal, which causes a problem.

  Therefore, in this embodiment, as shown in FIGS. 1 (A) and 1 (B), there are provided restricting portions (210 and 220) for restricting the movement of the elongated portions (21 and 22) of the band. Thereby, the movement to directions other than an extension direction (2nd direction) can be controlled, guiding the extension direction (21 and 22) movement to the extension direction (1st direction). Therefore, even when the subject moves, it is possible to maintain the state in which the sensor unit 90 is pressed against the subject with a given pressure. As a result, erroneous detection of sensor signals can be prevented.

2. Detailed Configuration Example of Biological Information Detection Device And the regulation unit 210 (220) regulates the movement of the extension unit 21 (22) in the second direction, while the first direction of the extension unit 21 (22). To guide the extension along.

  Accordingly, for example, the band portion 11 (12) can be extended in accordance with the circumference of the arm of the subject, and the sensor portion 90 can be pressed against the subject with a given pressure. Further, even when the subject wears the biological information detection device 100 and the circumference of the part around which the band part 11 (12) is wound changes, the extension part 21 (22) is automatically extended. Thus, it is possible to maintain a state in which the sensor unit 90 is pressed against the subject with a given pressure.

  The configuration of the biological information detection apparatus 100 shown in FIGS. 1A and 1B will be described more specifically. The biological information detection apparatus 100 includes a first band unit 11, a first band unit 11, and Have different second band portions 12. The first band portion 11 has a first extension portion 21, and the second band portion 12 has a second extension portion 22. Furthermore, the biological information detection device 100 is provided at a position corresponding to the first extension part 21 and a second extension part 22 provided at a position corresponding to the first extension part 21. Different from the second restricting portion 220.

  Accordingly, it is possible to restrict the movement of the first extension part 21 in the second direction and to restrict the movement of the second extension part 22 in the second direction.

  Further, as shown in FIG. 4A, the restricting portion 210 (220) includes an inner surface ISF1 and an inner surface 211 (221) opposite to the first side surface SS1 of the elongated portion 21 (22). The side surface ISF2 has a second wall surface 212 (222) facing the second side surface SS2 of the elongated portion 21 (22).

  In other words, the restricting portion 210 (220) includes a first wall surface 211 (221) and a second wall surface 212 (222) facing the first wall surface 211 (221). The extending portion 21 (22) intersects the second direction, intersects the first side surface SS1 facing the inner surface of the first wall surface 211 (221), the second direction, and the second direction. A second side surface SS2 facing the inner side surface of the wall surface 212 (222).

  Thereby, it becomes possible to restrict the movement of the extension part 21 (22) in the second direction.

  Further, as shown in FIG. 4B, the restricting portion 210 (220) has an inner surface ISF3 facing the bottom surface BS of the elongated portion 21 (22), and the outer surface OSF is covered when the biological information detecting device 100 is mounted. It has a bottom surface 213 (223) that faces the biological surface LF of the specimen.

  Therefore, when the sensor unit 90 is pressed against the subject and the band portion 11 (12) is wound, the bottom surface 213 (223) of the regulating unit 210 is also pressed against the living body surface LF of the subject, and the bottom surface 213 (223) and the subject are A frictional force acts between the living body surface LF of the specimen.

  As a result, it is possible to fix the band portion 11 (12) while being pressed against the living body surface LF of the subject. Further, by providing the bottom surface 213 (223), the gap between the first wall surface 211 (221) and the second wall surface 212 (222) of the restricting unit 210 and the living body surface LF of the subject is closed, and the band unit 11 It is possible to prevent (12) from passing through the gap and being displaced.

  Further, as shown in FIG. 4C, the restricting portion 210 (220) may have an upper surface 214 (224) in which the inner surface ISF4 faces the upper surface US of the extending portion 21 (22).

  In this case, the restricting portion 210 (220) has an appearance as shown in FIG. The restricting portion 210 (220) having such an appearance has high designability and makes it possible to prevent the extending portion 21 (22) from being seen from the outside. That is, it is possible to improve the design of the biological information detection apparatus 100. In addition, the regulation part 210 (220) of FIG. 5 has the attachment part 215 (225) which attaches the regulation part 210 (220) to the case part 30. FIG.

  Furthermore, since the restricting portion 210 (220) has the upper surface 214 (224), the upper side of the first wall surface 211 (221) and the second wall surface 212 (222) of the restricting portion 210 is connected to the band portion 11. It is possible to prevent (12) from jumping over and shifting.

  Moreover, the 1st extending | stretching part 21 has a 1st slit formation area | region in which 1 or a some slit is formed, and the 2nd extending | stretching part 22 is a 2nd slit in which a 1 or several slit is formed. It has a formation area. The first slit forming region or the second slit forming region is not limited to the shape shown in FIG. 1A and FIG. 1B described above, for example, FIG. 6A to FIG. (SL1-SL5) as shown in FIG.

  And when the biological information detection apparatus 100 has two extension parts of the 1st extension part 21 and the 2nd extension part 22, the length relationship of a slit formation area and an extension part is shown, for example in Drawing 7 (A). ) And the relationship shown in FIG. FIG. 7A illustrates the state of the first extension portion 21 (or the second extension portion 22) when it is not extended (or during the first extension), and FIG. The state at the time of the expansion | extension (or at the time of 2nd expansion | extension) of 1 expansion | extension part 21 (or 2nd expansion | extension part 22) is illustrated.

  Here, as shown in FIGS. 7A and 7B, the length of the first slit forming region in the first direction when the first extending portion 21 is not extended is L11, Let L21 be the length of the first restricting portion 210 in the first direction. Similarly, the length of the second slit forming region in the first direction when the second extending portion 21 is not extended is L12, and the length of the second restricting portion 210 in the first direction is L22. And Furthermore, the length of change in the wrist circumference due to the movement of the wrist when the case unit 30 is attached to the wrist of the subject is defined as LD.

  In this case, in the biological information detecting apparatus 100 of the present embodiment, L11 <L21 ≦ L11 + LD / 2 and L12 <L22 ≦ L12 + LD / 2 are satisfied. That is, when the first extending portion 21 is not extended, the length L11 of the slit forming region SL of the first extending portion 21 is equal to the length L21 of the first restricting portion 210 as shown in FIG. Becomes shorter (L11 <L21), and the slit forming region SL of the first extending portion 21 is hidden by the first restricting portion 210. On the other hand, when the first extending portion 21 is extended, the length of the slit forming region SL ′ of the first extending portion 21 becomes L11 + LD / 2 as shown in FIG. Is equal to or longer than L21 (L21 ≦ L11 + LD / 2), and a part of the slit forming region SL ′ of the first extending portion 21 protrudes from the first restricting portion 210. The same applies to the length relationship between the second restricting portion 220 and the second extending portion 22. When the change length of the circumference of the wrist of the subject is LD, the reason why the change length of the slit formation region is LD / 2 is that the slit formation region of the first extension portion 21 and the second extension This is because the slit forming region of the portion 22 changes by the same length.

  Thereby, the length of the restricting portion 210 (220) is set to a length that does not impair the design of the biological information detecting device 100 and can restrict the movement of the extending portion 21 (22) in the second direction. Is possible.

  In addition, as described with reference to FIGS. 1A to 7B, the biological information detection apparatus 100 according to the present embodiment does not necessarily include two sets of the extension unit and the regulation unit corresponding thereto. Instead, as shown in FIGS. 8A and 8B, only one set of the extending portion 21 and the restriction portion 210 corresponding thereto may be provided. In the example of FIGS. 8A and 8B, only the first band portion 11 has the extending portion 21 and the restricting portion 210, and the extending portion 21 is formed with one or more slits. It has a slit forming area. Other configurations are the same as the configurations in FIGS. 1A and 1B, and thus description thereof is omitted.

  In this case, when the length in the first direction of the slit forming region when the extension portion 21 is not extended is L1, and the length of the restriction portion 210 in the first direction is L2, It is desirable that L2> L1. That is, when the extending portion 21 is not extended, the length L1 of the slit forming region SL of the extending portion 21 is shorter than the length L2 of the restricting portion 210 (L1 <L2), as shown in FIG. 9A. The slit forming area SL of the extending part 21 is hidden by the restricting part 210.

  This makes it possible to improve the design of the biological information detecting device 100 by hiding the slit forming region of the extending part 21 behind the restricting part 210 when not extending.

  Further, when the change length of the wrist circumference due to the movement of the wrist when the case unit 30 is attached to the subject's wrist is LD, it is desirable that L1 <L2 ≦ L1 + LD. That is, at the time of extension of the extension part 21, as shown in FIG. 9B, the length of the slit formation region SL ′ of the extension part 21 is L1 + LD, which is not less than the length L2 of the regulation part 210 (L2 ≦ L1 + LD). In addition, a part of the slit forming region SL ′ of the extending part 21 protrudes from the restricting part 210. Unlike the examples of FIGS. 7A and 7B, when the change length of the circumference of the wrist of the subject is LD, the reason why the change length of the slit formation region is also LD is one reason. This is because only the slit forming region of the elongated portion 21 can cope with the change in the wrist circumference.

  Accordingly, similarly to the example described with reference to FIGS. 7A and 7B, the length of the restricting portion 210 can be reduced without impairing the design of the biological information detecting device 100 and the length of the extending portion 21. It is possible to make the length such that the movement in the direction 2 can be restricted.

  Further, as shown in FIG. 1A, FIG. 8A, and the like, the extending portion 21 (22) and the regulating portion 210 (220) are the same as the band portion 11 (12) and the case in the band portion 11 (12). It is provided on the attachment position side of the part 30.

  In other words, the extension part 21 (22) and the restricting part 210 (220) have one end of the band part 11 (12) close to the attachment position with the case part 30 and the other end of the band part 11 (12) far from the attachment position. And provided at one end.

  Thereby, for example, when the subject wears the biological information detection apparatus 100, the position of the extension unit 21 (22) and the regulation unit 210 (220) is more reliable than the configuration in which the position is opposed to the sensor unit 90. In addition, it is possible to suppress the floating of the sensor unit 90.

  Further, the restricting portion 210 (220) may be attached to the case portion 30 together with the elongated portion 21 (22) of the band portion 11 (12) at the attachment position of the band portion 11 (12) and the case portion 30.

  As a result, the positions of the restricting portion 210 (220) and the extending portion 21 (22) are relatively displaced, and the restricting portion 210 (220) cannot restrict the movement of the extending portion 21 (22) in the second direction. Can be prevented.

  As a specific example of attachment, there is a first attachment example as shown in FIGS. 10 (A) and 10 (B). The perspective view of FIG. 10A shows a state before the spring bar BB is inserted in the first attachment example. Moreover, the figure shown to FIG. 10 (B) has shown the attachment state in the 1st attachment example.

  For example, in the example of FIG. 10A and FIG. 10B, the hole portion HL1 and the hole portion HL5 are provided in the case portion 30, and the hole portion HL3 is provided in the extension portion 21 (22) of the band portion 11 (12). The hole HL2 and the hole HL4 are provided in the restriction part 210 (220). Then, by inserting a common bar member (spring bar) BB into these holes (HL1 to HL5), the restricting portion 210 (220) is an extended portion of the band portion 11 (12) at the mounting position. It is attached to the case part 30 together with 21 (22).

  However, this embodiment is not limited to the attachment method of FIG. 10 (A) and FIG. 10 (B). For example, the second attachment example shown in FIG. 11 may be employed.

  In the second attachment example, the shape of the attachment position of the case portion 30 is different from that of the first attachment example, and the case portion 30 has a hole portion HL3. And the shape of the attachment position of the expansion | extension part 21 (22) also changes according to it, and the expansion | extension part 21 (22) has the hole HL2 and the hole HL4. The restriction unit 210 (220) is the same as the example of FIG.

  Then, similarly to the example of FIG. 10B, the common bar member (spring bar) BB is inserted into these hole parts (HL1 to HL5), so that the restricting part 210 (220) at the mounting position. Is attached to the case portion 30 together with the elongated portion 21 (22) of the band portion 11 (12).

  Thereby, it becomes possible to prevent relative displacement of the case part 30, the restricting part 210 (220) and the extending part 21 (22).
