As described above, in FIG. 3, the living body information detection apparatus 400 is reduced in size by notifying a user of necessary minimum information by light emission of the light emitting unit 72 without providing a display unit such as an LCD. In addition, since the display unit is not provided in the biological information detection apparatus 400, the appearance of the biological information detection apparatus 400 can be improved.

  FIG. 4 shows a functional block diagram of the biological information detection apparatus of this embodiment. In FIG. 4, the biological information detection apparatus includes a sensor unit 40, a body motion sensor unit 170, a vibration generation unit 180, a processing unit 200, a storage unit 240, a communication unit 250, an antenna 252, and a notification unit 260. Note that the biological information detection apparatus of the present embodiment is not limited to the configuration of FIG. 4, and various modifications such as omitting some of the components, replacing with other components, and adding other components. Implementation is possible.

  The sensor unit 40 detects biological information such as a pulse wave, and includes a light receiving unit 42 and a light emitting unit 44. A pulse wave sensor (photoelectric sensor) is realized by the light receiving unit 42, the light emitting unit 44, and the like. The sensor unit 40 outputs a signal detected by the pulse wave sensor as a pulse wave detection signal.

  The body motion sensor unit 170 outputs a body motion detection signal that is a signal that changes according to body motion, based on sensor information of various sensors. The body motion sensor unit 170 includes, for example, an acceleration sensor 172 as a body motion sensor. The body motion sensor unit 170 may include a pressure sensor, a gyro sensor, or the like as the body motion sensor.

  The processing unit 200 performs various signal processing and control processing using the storage unit 240 as a work area, for example, and can be realized by a processor such as a CPU or a logic circuit such as an ASIC. The processing unit 200 includes a signal processing unit 210, a pulsation information calculation unit 220, and a notification control unit 230.

Do. For example, the signal processing unit 210 includes a body movement noise reduction unit 212. Based on the body motion detection signal from the body motion sensor unit 170, the body motion noise reduction unit 212 performs a process of reducing (removing) body motion noise that is noise caused by body motion from the pulse wave detection signal. Specifically, for example, noise reduction processing using an adaptive filter or the like is performed.

  The pulsation information calculation unit 220 performs pulsation information calculation processing based on the signal from the signal processing unit 210 and the like. The pulsation information is information such as the pulse rate. Specifically, the pulsation information calculation unit 220 obtains a spectrum by performing frequency analysis processing such as FFT on the pulse wave detection signal after the noise reduction processing in the body motion noise reduction unit 212, and obtains the spectrum. In FIG. 5, processing is performed in which a representative frequency is a heartbeat frequency. A value obtained by multiplying the obtained frequency by 60 is a commonly used pulse rate (heart rate). Note that the pulsation information is not limited to the pulse rate itself, and may be other various information (for example, the frequency or cycle of the heartbeat) representing the pulse rate, for example. Moreover, the information which represents the state of pulsation may be sufficient, for example, it is good also considering the value showing the blood volume itself as pulsation information.

  The notification control unit 230 controls the notification unit 260. The notification unit 260 (notification device) notifies the user of various types of information under the control of the notification control unit 230. As the notification unit 260, for example, a light emitting unit 72 such as an LED of FIG. 7 can be used. In this case, the notification control unit 230 controls lighting, blinking, and the like of the light emitting unit 72 by controlling the current flowing through the LED. Note that the notification unit 260 may be a display unit such as an LCD, a buzzer, or the like.

  The notification control unit 230 controls the vibration generation unit 180. The vibration generator 180 notifies the user of various types of information by vibration. The vibration generator 180 can be realized by a vibration motor (vibrator), for example. For example, the vibration motor generates vibration by rotating an eccentric weight. Specifically, eccentric weights are attached to both ends of the drive shaft (rotor shaft) so that the motor itself swings. The vibration of the vibration generator 180 is controlled by the notification controller 230. The vibration generator 180 is not limited to such a vibration motor, and various modifications can be made. For example, the vibration generating unit 180 may be realized by a piezo element or the like.

  For example, a start-up notification when the power is turned on, a notification of the success of the first pulse wave detection, a warning when a pulse wave cannot be detected continues for a certain period of time, and a notification when the fat burning zone is moved In addition, a warning at the time of battery voltage drop, a notification of a wake-up alarm, or a notification such as an email or a telephone from a terminal device such as a smartphone can be performed. Such information may be notified by the light emitting unit 720 or may be notified by both the vibration generating unit 230 and the light emitting unit 720.

  The communication unit 250 performs communication processing with the external terminal device 420 as described with reference to FIG. For example, a wireless communication process is performed according to a standard such as Bluetooth (registered trademark). Specifically, the communication unit 250 performs a signal reception process from the antenna 252 and a signal transmission process to the antenna 252. The function of the communication unit 250 can be realized by a logic circuit such as a communication processor or ASIC.

2. Sensor Unit FIG. 5A shows a detailed configuration example of the sensor unit 40. The sensor unit 40 includes a light receiving unit 42 and a light emitting unit 44. The light receiving unit 42 and the light emitting unit 44 are mounted on the sensor substrate 45. The light receiving unit 42 receives light (reflected light, transmitted light, etc.) from the subject. The light emitting unit 44 emits light to the subject. For example, when the light emitting unit 44 emits light to the subject and the light is reflected by the subject (blood vessel), the light receiving unit 42 receives and detects the reflected light. The light receiving unit 42 can be realized by a light receiving element such as a photodiode. The light emitting unit 44 can be realized by a light emitting element such as LED. For example, the light receiving unit 42 can be realized by a PN junction diode element or the like formed on a semiconductor substrate. In this case, an angle limiting filter for narrowing the light receiving angle and a wavelength limiting filter for limiting the wavelength of light incident on the light receiving element may be formed on the diode element.

  Taking a pulse meter as an example, the light from the light emitting unit 44 travels inside the subject and diffuses or scatters in the epidermis, dermis, subcutaneous tissue, and the like. Thereafter, this light reaches the blood vessel (detected site) and is reflected. At this time, part of the light is absorbed by the blood vessels. Then, the light absorption rate in the blood vessel changes due to the influence of the pulse, and the amount of reflected light also changes. Therefore, the light receiving unit 42 receives this reflected light and detects the change in the amount of biological information. It becomes possible to detect the pulse rate and the like.

  A light shielding part 46 (light shielding wall) is provided between the light receiving part 42 and the light emitting part 44. For example, the light shielding unit 46 shields light from the light emitting unit 44 from directly entering the light receiving unit 42.

  The sensor unit 40 is provided with apertures 47 and 48. The diaphragm units 47 and 48 squeeze light from the subject or light from the light emitting unit 44 in the optical path between the subject and the sensor unit 40. In FIG. 5A, the diaphragm portions 47 and 48 are provided between the translucent member 50 and the sensor portion 40. However, the diaphragms 47 and 48 may be provided between the translucent member 50 and the subject or in the translucent member 50. Further, the light shielding part 46 and the diaphragm parts 47 and 48 may be integrally formed by, for example, processing a metal sheet metal.

  The translucent member 50 is provided on the surface of the biological information detection apparatus that is in contact with the subject, and transmits light from the subject. The translucent member 50 contacts the subject when measuring the biological information of the subject. For example, the convex part 52 (detection window) of the translucent member 50 contacts the subject. The surface shape of the convex portion 52 is desirably a curved surface shape (spherical shape), but is not limited to this, and various shapes can be adopted. Moreover, the translucent member 50 should just be transparent with respect to the wavelength of the light from a subject, and may use a transparent material and may use a colored material.

  Around the convex portion 52 of the translucent member 50, a groove portion 54 is provided for suppressing pressure fluctuation and the like. Further, when the surface on the side where the convex portion 52 is provided in the translucent member 50 is the first surface, the translucent member 50 corresponds to the convex portion 52 on the second surface on the back side of the first surface. A recessed portion 56 is provided at a position to be used. In the space of the concave portion 56, a light receiving portion 42, a light emitting portion 44, a light shielding portion 46, and aperture portions 47 and 48 are provided.

  Further, on the surface on the subject side of the biological information detecting device, a pressure suppressing portion 58 that suppresses the pressure applied by the convex portion 52 to the subject (the wrist skin) is provided. In FIG. 5A, the pressing suppression portion 58 is provided so as to surround the convex portion 52 of the translucent member 50.

  In FIG. 5A, the height of the convex portion 52 in the direction orthogonal to the surface on the subject side of the biological information detecting device is HA (for example, the height of the apex of the curved surface shape of the convex portion 52), and the pressure is suppressed. When the height of the portion 58 is HB (for example, the height at the highest place) and the value obtained by subtracting the height HB from the height HA (difference between the heights HA and HB) is Δh, Δh = HA− The relationship of HB> 0 is established. For example, the convex part 52 protrudes from the pressing suppression part 58 to the subject side so that Δh> 0. That is, the convex portion 52 protrudes toward the subject side by Δh from the pressure suppression portion (pressure suppression surface) 58.

  Thus, by providing the convex part 52 that satisfies Δh> 0, for example, it is possible to apply an initial pressure to the subject to exceed the venous vanishing point, for example. In addition, by providing the pressure suppression unit 58 for suppressing the pressure applied to the subject by the convex portion 52, it is possible to minimize the pressure fluctuation in the usage range in which the biological information is measured by the biological information detection device. Therefore, noise components and the like can be reduced. Further, if the convex portion 52 protrudes from the pressing suppression portion 58 so as to satisfy Δh> 0, the pressing suppression portion 58 contacts the subject after the convex portion 52 contacts the subject and gives an initial pressure. Thus, the pressure applied to the subject by the convex portion 52 can be suppressed. Here, the vein vanishing point is reduced to such an extent that the signal caused by the vein superimposed on the pulse wave signal disappears or does not affect the pulse wave measurement when the convex portion 52 is brought into contact with the subject and the pressure is gradually increased. It is a point.

  For example, in FIG. 5B, the horizontal axis represents the load generated by the load mechanism (mechanism composed of a band part, a buckle part, etc.) of the biological information detection device, and the vertical axis represents the convex part 52 covered. It represents the pressure applied to the specimen (pressure applied to the blood vessel). Then, it is assumed that the amount of change in the pressing of the convex portion 52 with respect to the load by the load mechanism that generates the pressing of the convex portion 52 is a pressing change amount. This amount of change in pressure corresponds to the inclination of the change characteristic of pressure against the load.

  In this case, the pressure suppression unit 58 has a second load range in which the load of the load mechanism is greater than FL1 with respect to the pressure change amount VF1 in the first load range RF1 in which the load of the load mechanism is 0 to FL1. The pressure applied to the subject by the convex portion 52 is suppressed so that the pressure change amount VF2 at RF2 is reduced. That is, in the first load range RF1 that is the initial pressing range, the pressing change amount VF1 is increased, while in the second load range RF2 that is the usage range of the biological information detecting device, the pressing change amount VF2 is decreased.

  That is, in the first load range RF1, the pressure change amount VF1 is increased to increase the inclination of the pressure change characteristic with respect to the load. Such a pressing with a large gradient of the change characteristic is realized by Δh corresponding to the protruding amount of the convex portion 52. That is, by providing the convex portion 52 that satisfies Δh> 0, even when the load by the load mechanism is small, it is possible to give the subject an initial pressure necessary and sufficient to exceed the venous vanishing point. become.

  On the other hand, in the second load range RF2, the pressure change amount VF2 is reduced to reduce the inclination of the pressure change characteristic with respect to the load. Such a pressing with a small inclination of the change characteristic is realized by pressing suppression by the pressing suppressing unit 58. In other words, the pressure suppression unit 58 suppresses the pressure applied to the subject by the convex portion 52, so that the variation in the pressure is minimized even when there is a load variation or the like in the usage range of the biological information detection device. It becomes possible to suppress. As a result, noise components can be reduced.

  In this way, it is possible to obtain a pulse wave detection signal having a higher M / N ratio (S / N ratio) by applying an optimized pressure (for example, about 16 kPa) to the subject. . That is, the signal component of the pulse wave sensor can be increased and the noise component can be reduced. Here, M represents the signal level of the pulse wave detection signal, and N represents the noise level.

  In addition, by setting the pressure range used for pulse wave measurement to a range corresponding to the second load range RF2, it is possible to suppress a minimum pressure fluctuation (for example, about ± 4 kPa), and a noise component Can be reduced.

3. Detailed Structure Example 3.1 Band Unit and Case Unit As described above, the biological information detection apparatus of the present embodiment includes the band unit 10, the case unit 30 attached to the band unit 10, and the sensor unit provided in the case unit 30 40 and a processing unit 200 that is provided in the case unit 30 and detects biological information based on a detection signal from the sensor unit 40.

  As shown in FIG. 6, the band unit 10 has a first curved inner surface 11 on the side facing the subject when worn, and the case unit 30 (top case 34) is formed on the inner surface 11 of the band unit 10. It has the outer surface 31 of the 2nd curved surface shape which opposes.

  For example, in FIG. 6, DR1 that is a downward direction is an inner direction that faces toward the subject, and DR2 that is an upward direction is an outer direction that faces outward from the subject. The inner surface 11 of the band portion 10 is a surface facing the direction DR1 that is the inner direction, and the outer surface 31 of the case portion 30 is a surface facing the direction DR2 that is the outer direction. Both the inner surface 11 of the band portion 10 and the outer surface 31 of the case portion 30 are curved shapes, for example, curved surfaces having the same curvature (curved shapes having substantially the same curvature). That is, the inner surface 11 of the central portion of the band portion 10 has a first curved surface shape with a curvature corresponding to the curvature of the wrist so as to fit when the band portion 10 is attached to the wrist. The outer surface 31 of the case portion 30 that is in close contact with the inner surface 11 has a second curved surface shape with a curvature corresponding to the curvature of the first curved surface shape of the inner surface 11.

  With the structure as shown in FIG. 6, when the biological information detection device is attached to the wrist, the thickness of the case part 30 in the direction DR1 can be reduced, and the volume occupied by the case part 30 can be reduced. Therefore, the biological information detection device can be reduced in size and weight, and the burden on the user when worn for a long time can be reduced. In addition, since the burden on the user when worn for a long time can be reduced in this way, it is possible to continuously measure biological information and provide a biological information detection device suitable for taking a life log of biological information Is possible.

  That is, in order to take a life log of biological information, the user must always wear the biological information detection device. However, if the biological information detection device is large or heavy, the burden on the user is increased. Therefore, there is a risk that the life log measurement of the biological information due to the constant wearing may be hindered.

  In this regard, in FIG. 6, the inner surface 11 of the band portion 10 and the outer surface 31 of the case portion 30 have curved surfaces with the same curvature, for example, thereby minimizing the volume occupied by the case portion 30 and increasing the thickness in the direction DR1. Can be thin. This facilitates the realization of a small and lightweight biological information detection device, and realizes a biological information detection device suitable for life log measurement.

  In addition, when the user uses the biological information detection device on a daily basis, the design (aesthetic appearance) of the biological information detection device is also an important factor. In this regard, by adopting the structure as shown in FIG. 6, it is possible to realize a living body information detecting apparatus having a simple, compact and stylish impression. Therefore, the motivation etc. about a user always wearing a living body information detecting device can be heightened, and a living body information detecting device suitable for life log measurement can be realized.

  In addition, the same curved surface shape may be sufficient as the 1st curved surface shape of the inner surface 11 of the band part 10, and the 2nd curved surface shape of the outer surface 31 of the case part 30, and a different curved surface shape may be sufficient as it. For example, the curvature of the first curved surface shape and the curvature of the second curved surface shape may be the same or different. For example, if the first curved surface shape and the second curved surface shape are the same curved surface shape (for example, a curved surface shape having the same curvature), the band portion 10 and the case portion 30 are fixed without a gap, and thus are not easily displaced. There is an advantage of becoming. On the other hand, if the first curved surface shape and the second curved surface shape are different curved surface shapes (for example, curved surface shapes having different curvatures), there is an advantage that the degree of freedom of design and design can be increased.

  Moreover, in this embodiment, the case part 30 has the top case 34 and the bottom case 36, and at least the top case 34 and the band part 10 are insert-molded. For example, the top case 34 (at least a part of the case part 30) and the band part 10 are integrally formed by insert molding.

  By performing insert molding, members of different materials can be integrally formed. For example, the band portion 10 is formed of a first material, and the top case 34 (case portion 30) is formed of a second material that is harder than the first material. That is, the band portion 10 is formed of a soft first material such as silicon resin, for example, in order to increase the fit to the wrist when worn. On the other hand, the top case 34 is formed of a hard second material such as plastic in order to prevent damage or failure of the built-in components. In addition, the material which forms the band part 10 and the top case 34 is not limited to this, For example, the band part 10 is formed with soft materials (for example, urethane) other than a silicone resin, or the top case 34 (case part 30) is formed. Various modifications such as formation with a material (for example, metal) other than plastic (polycarbonate) are possible.

  By performing the insert molding, the band portion 10 and the top case 34 of different materials can be easily formed integrally as described above. For example, such an integral formation is possible by performing insert molding in which a silicon resin or the like to be the band portion 10 is poured into the top case 34 set in a mold (mold for integral formation).

  By adopting such an insert molding technique, the band portion 10 and the top case 34 can be formed of materials suitable for each. For example, by forming the band portion 10 with a soft material, it is possible to increase the fit when worn on the wrist. Further, by forming the top case 34 and the bottom case 36 from a hard material, damage or failure of the built-in parts of the case portion 30 can be suppressed. And according to insert molding, since the process of adhering and attaching the top case 34 to the band part 10 becomes unnecessary and the manufacturing process can be simplified, the cost of the biological information detecting device can be reduced. Become.

  As shown in FIG. 6, in a state where the band portion 10 and the top case 34 are integrally formed, a part of the outer surface 31 of the top case 34 is exposed in the outer direction DR2, and the light emission window portion is exposed to the exposed portion. 32 is provided. The light from the light emitting part 72 is emitted in the outer direction DR2 through the light emitting window part 32 provided in the exposed part, and various information can be notified to the user.

  In this way, various information can be notified to the user using the light emitting unit 72 without providing a display unit such as an LCD. By not providing a display unit such as an LCD in the case unit 30, the biological information detection device can be reduced in size and weight, and the aesthetic appearance can be improved, thereby realizing a biological information detection device suitable for life log measurement.

  Moreover, the hole part 18 which accommodates the top case 34 (at least one part of the case part 30) is provided in the band part 10 (inner surface side of the band part 10). Specifically, a hole 18 having a shape corresponding to the shape of the outer surface side of the top case 34 is formed on the inner surface side of the central portion of the band portion 10.

  In this way, the top case 34 is stored in the hole 18 so as to cover the top case 34 with the band part 10, and the band part 10 and the top case 34 can be formed integrally. Further, by providing such a hole portion 18, the thickness in the direction DR1 can be minimized, and the biological information detecting apparatus can be downsized.

The decorative cover 60 is bonded to the outer surface of the top case 34 with a double-sided tape 62. By providing such a decorative cover 60, it is possible to improve the beauty of the biological information detecting device.

  70 is a flexible substrate, and 74 is a double-sided tape. A light emitting unit 72 such as an LED is mounted on the flexible substrate 70. The flexible substrate 70 is provided with the antenna 252 shown in FIG. Specifically, a metal pattern (not shown) of the antenna 252 is formed on the flexible substrate 70.

  Reference numeral 80 is a secondary battery (battery), 82 is a double-sided tape, and 84 is a holder for the secondary battery 80. The secondary battery 80 is bonded to the holder 84 with a double-sided tape.

  Reference numeral 160 denotes a circuit board (main board), 170 denotes a body motion sensor unit, 180 denotes a vibration generation unit (vibration motor), and 200 denotes a processing unit. The body motion sensor unit 170 and the processing unit 200 are mounted on the circuit board 160.

  Reference numeral 45 is a sensor substrate, and 49 is a connection cable. As shown in FIG. 5A, a light receiving unit 42, a light emitting unit 44, and the like are mounted on the sensor substrate 45. The sensor board 45 and the circuit board 160 are electrically connected by a connection cable 49. Reference numerals 90, 92 and 96 are buffer members.

  36 is a bottom case, and 97 and 98 are screws. The top case 34 and the bottom case 36 are fixed with screws 97 and 98.

3.3 Light Emitting Unit, Flexible Substrate As shown in FIGS. 7 and 8, in the biological information detection apparatus of the present embodiment, a flexible substrate 70 in which a light emitting unit 72 is disposed is provided on the back side of the outer surface 31 of the case unit 30. It has been. Specifically, the flexible substrate 70 is provided on the DR1 direction side (directly below the top case 34) of the top case 34 constituting the case unit 30. For example, the flexible substrate 70 is provided between the top case 34 and the secondary battery 80. The flexible substrate 70 is bonded to the inner surface of the top case 34 (the back surface of the outer surface 31) with a double-sided tape 74. A plurality of light emitting units 72 (LEDs) are mounted on the flexible substrate 70, and light from the light emitting units 72 is irradiated to the outside through the light emitting window unit 32.

  In this way, it is possible to notify the user of various types of information by turning on or flashing the light of the light emitting unit 72. And since this light emission part 72 is mounted in the thin flexible substrate 70, it can contribute to thickness reduction of the thickness of the case part 30. FIG. As described with reference to FIG. 6, the outer surface 31 of the case portion 30 has a curved surface shape corresponding to the curved surface of the inner surface 11 of the band portion 10, and the back surface of the outer surface 31 also has a curved surface shape. Therefore, if the flexible substrate 70 is used, the flexible substrate 70 is bent and arranged in a curved shape so as to match the curved shape of the back surface of the outer surface 31, and the light emitting unit 72 can be mounted on the flexible substrate 70.

  7 and 8, the top case 34 has a light emission window 32 of the light emission part 72, and the top case 34 and the light emission window 32 are insert-molded. For example, the top case 34 and the light emitting window 32 are integrally formed by insert molding. For example, by performing insert molding in which a translucent resin or the like is poured into a portion of the light emitting window 32 of the top case 34 set in a mold, such integral formation becomes possible.

  For example, the light emitting window 32 is formed of a light transmissive material, and the top case 34 is formed of a non-light transmissive material. Specifically, the top case 34 (case portion 30) is made of plastic (polycarbonate) colored black or the like, and the light emitting window portion 32 is made of translucent plastic (polycarbonate) or the like. The “translucency” may be transparent to the wavelength of light from the subject and may be colored (for example, milky white). Further, “non-translucent” means that light having a wavelength that can be detected by the biological information detection apparatus is not transmitted.

  As described above, when the top case 34 and the light emitting window 32 are integrally formed by insert molding, the top case 34 formed of a non-translucent material and the light emitting window 32 formed of a translucent material are provided. It can be formed in a simple and less manufacturing process. Therefore, the cost of the biological information detection device can be reduced.

  In the manufacture by insert molding, first, the top case 34 and the light emitting window 32 are integrally formed by insert molding. Next, the top case 34 in which the light emitting window portion 32 is insert-molded and the band portion 10 are integrally formed by insert molding.

  In addition, the flexible substrate 70 disposed on the back surface side of the outer surface 31 of the case portion 30 is provided with an antenna 252 (see FIG. 4) for communication (for close proximity wireless communication). Specifically, a metal pattern constituting the antenna 252 is formed on the flexible substrate 70. As the metal pattern in this case, various patterns such as a ring shape and a zigzag shape can be assumed.

  If the antenna 252 is formed on the flexible substrate 70 in this way, the antenna 252 can be disposed at a position close to the outer surface 31 of the case portion 30, so that the receiving sensitivity of the antenna 252 can be improved. Further, by sharing the flexible substrate 70 for the arrangement of the light emitting portion 72 and the formation of the antenna 252, the number of components can be reduced, and the size of the apparatus can be reduced.

3.4 Circuit Board, Secondary Battery, Vibration Generation Unit, Buffer Member As shown in FIGS. 7 and 8, the case unit 30 is provided with a circuit board 160 on which the processing unit 200 is mounted. The circuit board 160 is, for example, a rigid board. As shown in the schematic cross-sectional view of the biological information detection apparatus in FIG. 9, the secondary battery 80 is disposed between the circuit board 160 and the top case 34 (the outer surface of the case unit 30). Specifically, the secondary battery 80 is provided between the back surface 33 of the top case 34 and the circuit board 160, and the back surface 33 of the top case 34 has a curved surface.

  The secondary battery 80 supplies power to the circuit board 160 (processing unit 200, body motion sensor unit 170), vibration generation unit 180, sensor unit 40, and the like. For example, by attaching the biological information detection device to the cradle, the terminal part of the cradle and the case terminal part 35 are electrically connected, and the secondary battery 80 is charged by the power from the cradle. As the secondary battery 80, for example, a lithium ion polymer battery or the like can be employed.

  In the present embodiment, the secondary battery 80 is disposed between the circuit board 160 and the top case 34. Therefore, the secondary battery 80 can be arranged by effectively utilizing the empty space on the DR2 direction side of the circuit board 160. For example, since the inner surface 33 of the top case 34 is a curved surface, a relatively wide empty space can be secured on the DR2 direction side of the circuit board 160. In the present embodiment, the secondary battery 80 having a large volume is disposed in this empty space. As a result, it is possible to place components that effectively use the space in the case portion 30, and the case portion 30 can be reduced in thickness and size.

  Further, the secondary battery 80 is repeatedly charged and the center of the secondary battery 80 swells as indicated by F1 in FIG. That is, the central portion expands in the DR2 direction side. As described above, the thickness of the sensor unit 30 is kept to a minimum, but if the secondary battery 80 expands due to such charging, there is a possibility that the clearance between the components cannot be obtained.

  In this regard, in this embodiment, the secondary battery 80 is provided between the back surface 33 of the top case 34 and the circuit board 160, and the back surface 33 of the top case 34 has a curved surface as shown in FIG. Therefore, an empty space on the DR2 direction side of the secondary battery 80 can be secured. For example, since a space of about 1 mm (about 30% in terms of battery volume ratio) can be secured in the central portion, this can be dealt with even when the central portion of the secondary battery 80 expands in the DR2 direction side.

  In the present embodiment, the case unit 30 is provided with a circuit board 160 on which the processing unit 200 is mounted and a vibration generating unit 180. As shown in FIGS. 7 and 8, the vibration generator 180 is provided on the first side SD1 side of the first side SD1 and the second side SD2 facing the circuit board 160. Specifically, the vibration generating unit 180 is disposed in the vicinity of the first side SD1 of the circuit board 160. The first and second sides SD1 and SD2 are sides corresponding to, for example, the short side of the circuit board 160. For example, it is considered that it is easy to secure a space on the short side of the circuit board 160 because of the structure. Therefore, if the vibration generating unit 180 is arranged on the first side SD1 side, which is the short side of the circuit board 160, a space is left. There is an advantage that space can be used effectively. However, the first side SD1 where the vibration generating unit 180 is disposed may be the long side of the circuit board 160.

  If the vibration generating unit 180 is provided in this manner, the vibration generating unit 180 can be arranged by effectively utilizing the empty space at the end of the circuit board 160. For example, in FIG. 9, there is an empty space at the end of the circuit board 160 on the DR4 direction side (end on the side SD1 side of the circuit board 160), and the vibration generator 180 is disposed in this empty space. For example, the vibration generating unit 180 is disposed between the back surface 33 of the top case 34 and the bottom case 36 at the end portion (right end portion) of the case portion 30 on the DR4 direction side. The direction DR3 is a direction orthogonal to the direction DR1, and the direction DR4 is a direction opposite to the direction DR3.

  In this way, by arranging the vibration generating unit 180 having a relatively large volume in the empty space on the DR4 direction side of the case unit 30, it is possible to arrange components using the space in the case unit 30 effectively. 30 can be reduced in thickness and size.

  In this embodiment, a body motion sensor unit 170 is mounted on the circuit board 160 in addition to the processing unit 200 (chip of the processing unit). By providing the body motion sensor unit 170, the body motion noise reduction processing described with reference to FIG. 4 can be performed.

  As shown in FIG. 9, when the distance between the vibration generating unit 180 and the body motion sensor unit 170 is LA and the distance between the vibration generating unit 180 and the processing unit 200 is LB, LA> LB. . Here, the distance LA is a distance between the representative position (center position) of the vibration generating unit 180 and the representative position (center position) of the body motion sensor unit 170. The distance LB is a distance between the representative position (center position) of the vibration generating unit 180 and the representative position (center position) of the processing unit 200. For example, the vibration unit 180 and the processing unit 200 are arranged on the first side SD1 side of the circuit board 160. On the other hand, the body motion sensor unit 170 is disposed on the second side SD2 side of the circuit board 160. That is, the vibration generating unit 180 is arranged at a distance away from the body motion sensor unit 170 as compared with the processing unit 200.

  By doing so, the distance between the vibration generating unit 180 and the body motion sensor unit 170 can be increased, and the adverse effect of the vibration generated by the vibration generating unit 180 can be reduced from reaching the body motion sensor unit 170. For example, as described above, when the vibration generating unit 180 is arranged on the first side SD1 side of the circuit board 160 in order to effectively use the space of the case unit 30, the body motion sensor unit 170 has the first side SD1. Is provided on the second side SD <b> 2 side opposite to. Therefore, the vibration generating unit 180 gives the body motion sensor unit 170 by separating the distance between the vibration generating unit 180 and the body motion sensor unit 170 while reducing the size of the case unit 30 by appropriately arranging the vibration generating unit 180. Adverse effects can be reduced.

  The case unit 30 is provided with a vibration generating unit 180, and a buffer member 90 is provided between the vibration generating unit 180 and the bottom case 36. That is, the buffer member 90 is provided on the DR1 direction side of the vibration generating unit 180.

  By providing the buffer member 90 in this way, it is possible to suppress a situation where a so-called chatter noise or the like is generated when the vibration generating unit 180 vibrates. Various types of information can be notified to the user with appropriate vibrations from which unpleasant vibrations are removed. Further, by providing the buffer member 90 and disposing the vibration generating portion 180 thereon, the vibration generating portion 180 can be stably supported in the case portion 30, and the occurrence of rattling or the like of parts can be prevented. Can be suppressed.

  The case unit 30 is provided with a circuit board 160 and a sensor board 45 on which the sensor unit 40 is mounted, and a buffer member 92 is provided between the circuit board 160 and the sensor board 45.

  By providing such a buffer member 92, it becomes possible to stably support the circuit board 160 and the sensor board 45 in the case portion 30, and it is possible to suppress the occurrence of rattling of components. For example, when the sensor substrate 45 is press-fit into the bottom case 36 and attached, the buffer member 92 is disposed above the sensor substrate 45, so that the attachment state by the press-fitting can be stabilized. In addition, as the buffer members 90 and 92, members, such as a urethane material, are employable, for example.

  5A, the sensor unit 40 includes a light receiving unit 42, a light emitting unit 44, and a translucent member 50 that transmits light emitted from the light emitting unit 44 and light incident on the light receiving unit 42. Have. The translucent member 50 is used as a cover part of the sensor part 40. In the present embodiment, the bottom case 36 and the translucent member 50 of the sensor unit 40 are also insert-molded. For example, the bottom case 36 and the translucent member 50 are integrally formed by insert molding. For example, by performing insert molding in which the material of the bottom case 36 is poured into the translucent member 50 (cover portion) set in the mold, such integral formation becomes possible.

  For example, the translucent member 50 is formed of a translucent material, and the bottom case 36 is formed of a non-translucent material. Specifically, the bottom case 36 is formed of non-translucent plastic (polycarbonate) colored in black or the like, like the top case 34. On the other hand, the translucent member 50 is formed of translucent plastic (polycarbonate) or the like.

  Thus, if the bottom case 36 and the translucent member 50 of the sensor unit 40 are integrally formed by insert molding, the bottom case 36 formed of a non-translucent material and the translucent formed of the translucent material. The optical member 50 can be integrally formed by a simple and less manufacturing process. Therefore, the cost of the biological information detection device can be reduced.

  Although the present embodiment has been described in detail as described above, it will be easily understood by those skilled in the art that many modifications can be made without departing from the novel matters and effects of the present invention. Accordingly, all such modifications are intended to be included in the scope of the present invention. For example, a term described at least once together with a different term having a broader meaning or the same meaning in the specification or the drawings can be replaced with the different term in any part of the specification or the drawings. Further, the configuration and operation of the biological information detection apparatus are not limited to those described in the present embodiment, and various modifications can be made.
