As shown in FIGS. 1 and 2, the electronic device 1 includes a main body 2 and a band 3.
The main body 2 includes support portions 2a that support the band 3 at the upper end position and the lower end position in the front view of FIG.

3 is an exploded view showing the configuration of the main body 2, FIG. 3 (A) is a perspective view from the front side, and FIG. 3 (B) is a perspective view from the back side.
4 is a diagram showing the structure of the main body 2, FIG. 4 (A) is a front view of the main body 2, FIG. 4 (B) is a cross-sectional view of the main body 2 taken along the line CC ′, and FIG. It is DD 'sectional drawing of the main body 2. FIG.
As shown in FIGS. 3 and 4, the main body 2 includes an outer case 10, an inner case 20, and a rotator 30, and the inner case 20 and the rotator 30 are assembled to the outer case 10. It has become.

The outer case 10 is a substantially cylindrical member that forms a frame of the main body 2, and has support portions 2 a that support the band 3 at two locations on the outer peripheral surface that are 180 degrees away from the central axis.
The inner peripheral surface of the outer case 10 is provided with a first boss receiving groove 10a and an outer case guide 10b.
The first boss receiving groove 10a has a width corresponding to a diameter of a first boss 21a to be described later, and extends in a direction along the generatrix from an end on the back surface side on the inner peripheral surface. As will be described later, the length of the first boss receiving groove 10a in the generatrix direction is such that the rotation of the rotating body 30 causes the inner case 20 to move in the axial direction with respect to the outer case 10 (the vertical direction when the back side is the gravity direction). In the direction). The first boss receiving groove 10a is provided at two positions 180 degrees apart from the center axis of the outer case 10.

  The outer case guide 10b protrudes in a claw shape from the inner peripheral surface of the outer case 10, and engages with a rotating body guide groove 31a described later to rotatably support the rotating body 30. Two external case guides 10b are provided at positions 180 degrees apart from the center axis of the external case 10. In the present embodiment, the outer case guide 10b is installed at the front end of the position where the first boss receiving groove 10a is provided.

  The internal case 20 includes a processor for controlling the electronic device 1, a storage device such as a ROM (Read Only Memory) or a RAM (Random Access Memory), a battery, and the like. A display 20a for displaying information is provided on the front side of the inner case 20, and a sensor 20b for detecting biological information (pulse, blood pressure, body temperature, etc.) is provided on the back side of the inner case 20. . The inner case 20 is a substantially columnar member, and has a large-diameter portion 21 having a diameter corresponding to the inner peripheral surface of the outer case 10, a smaller diameter than the large-diameter portion 21, and an inner peripheral surface of the rotating body 30. A small diameter portion 22 having a corresponding diameter.

  The large-diameter portion 21 has first bosses 21a that engage with the first boss receiving grooves 10a at two locations on the outer peripheral surface that are 180 degrees apart from the central axis. The first boss 21a is a columnar projection that projects from the outer peripheral surface of the large diameter portion 21. Since the first boss 21a is movable in the generatrix direction in the first boss receiving groove 10a, the rotation of the rotating body 30 allows the inner case 20 to move in the axial direction with respect to the outer case 10 as described later. Has become. A sensor 20b for detecting biological information is provided on the back side of the large-diameter portion 21. When detecting the biological information, the sensor 20b can perform more accurate detection by being closely attached to the living body.

  The small diameter portion 22 is provided with a second boss 22a that engages with the second boss receiving groove 31b at two places on the outer peripheral surface that is 180 degrees away from the central axis. The second boss 22a is a column-shaped projection protruding from the outer peripheral surface of the small diameter portion 22. The radius from the central axis of the inner case 20 to the tip of the second boss 22a is set so as not to exceed the radius of the outer peripheral surface of the large diameter portion 21. Since the second boss 22a is movable along the second boss receiving groove 31b installed obliquely to the generating line, the rotation of the rotating body 30 causes the inner case 20 to move with respect to the rotating body 30 as described later. To move in the axial direction. In the present embodiment, the first boss 21a and the second boss 22a are installed at positions shifted by 90 degrees from the center axis. Further, a display 20a for displaying various information such as a detection result of the sensor 20b and time is provided on the front side of the small diameter portion 22.

  The rotating body 30 is installed on the front side of the outer case 10 and forms a frame surrounding the display 20a when the inner case 20 is installed in the outer case 10. In addition, the rotating body 30 is rotatable about a central axis, and rotates without moving in the axial direction with respect to the outer case 10, and moves the inner case 20 in the axial direction according to the rotation. Specifically, the rotating body 30 includes an inner cylindrical portion 31 inserted into the outer case 10 and an annular frame portion 32 arranged on the front side of the outer case 10.

FIG. 5 is a perspective view showing the configuration of the rotating body 30. FIG. 5 shows a perspective view from the back side.
As shown in FIG. 5, the inner cylindrical portion 31 has a substantially cylindrical structure having an outer peripheral surface corresponding to the inner peripheral surface of the outer case 10. A rotating body guide groove 31a that engages with the outer case guide 10b is provided at a location. The two rotating body guide grooves 31a are provided along a circle where the outer peripheral surface of the inner cylindrical portion 31 intersects a plane perpendicular to the central axis (that is, along the circumferential direction of the outer peripheral surface). That is, even when the rotating body 30 rotates, the rotating body guide groove 31a engages without moving the outer case guide 10b in the axial direction. In the present embodiment, each rotating body guide groove 31a is installed in a range of 90 degrees with respect to the central axis. The range in which the rotating body guide groove 31a is set is set in accordance with the length of a second boss receiving groove 31b described later.

In addition, the inner cylindrical portion 31 has second boss receiving grooves 31b that engage with the second bosses 22a at two locations on the inner peripheral surface that are 180 degrees apart from the central axis. The second boss receiving groove 31b, on the inner peripheral surface of the inner cylindrical portion 31, is a straight portion 311b extending from the rear end to the bending point in the generatrix direction, and is bent from the straight portion 311b and is located in the middle of the inner circumferential surface. The oblique portion 312b extends in the circumferential direction (that is, obliquely intersects with the bus) while approaching the front end portion to the end position. Therefore, when the second boss 22a is engaged with the second boss receiving groove 31b, the rotating body 30 is rotated after the second boss 22a passes through the rectilinear portion 311b and abuts on the position of the bending point. Thereby, the second boss 22a can move in the range from the bending point of the oblique portion 312b in the second boss receiving groove 31b to the end position. Thereby, in conjunction with the rotation of the rotating body 30, the inner case 20 moves to the front side or the back side along the central axis.
The length of the linear portion 311b and the oblique portion 312b (that is, the second boss receiving groove 31b) of the rotating body 30 in the central axis direction (the distance the second boss 22a moves in the central axis direction) is equal to the first length of the outer case 10. This length corresponds to the length of the one boss receiving groove 10a in the central axis direction (the distance the first boss 21a moves in the central axis direction). Therefore, when the rotating body 30 is rotated from the state in which the second boss 22a is engaged at the position of the bending point, the second boss 22a moves from the rectilinear portion 311b (the bending point) to the oblique portion 312b, The first boss 21a can move in the first boss receiving groove 10a, and in conjunction with the rotation of the rotating body 30, the inner case 20 moves to the front side or the back side along the central axis.

  The frame portion 32 is provided on the front side of the inner cylindrical portion 31 and is configured as an annular member having a predetermined width in a direction in which the radius increases from an inner circumferential surface integrally connected to the inner circumferential surface of the inner cylindrical portion 31. Is done. The radius of the frame 32 is set such that the outer circumference of the frame 32 matches the radius of the outer peripheral surface of the outer case 10. On the front side of the frame 32, an index 32a indicating the rotational position of the frame 32 is provided at a position 180 degrees away from the center axis.

Next, a description will be given of a change in the relationship between the members when the rotating body 30 is rotated.
FIG. 6 is a schematic diagram showing a change in the positional relationship between the inner peripheral surface of the rotating body 30 and the inner case 20 including the second boss 22a, and FIG. 6A shows that the second boss 22a has the second boss receiving portion. FIG. 6B shows the case where the second boss 22a is at the bending point of the second boss receiving groove 31b when the groove 31b is at the end position.
FIG. 7 is a partial sectional view schematically showing a change in the engagement relationship between members. Specifically, in FIG. 7, when the inner case 20 is on the front side and on the back side, a part of the AA ′ sectional view and a part of the BB ′ sectional view of FIG. It is schematically shown on an enlarged scale.

As described above, in the electronic device 1, the first boss 21 a of the inner case 20 and the first boss receiving groove 10 a of the outer case 10 are engaged, and the second boss 22 a of the inner case 20 and the The two boss receiving grooves 31b are engaged, and the outer case guide 10b of the outer case 10 and the rotating body guide groove 31a of the rotating body 30 are engaged.
When the rotating body 30 is rotated left in a front view, the rotating body guide groove 31a of the rotating body 30 is engaged with the outer case guide 10b of the outer case 10, as shown in FIG. Therefore, the rotating body 30 rotates without moving in the axial direction with respect to the outer case 10. At this time, in the inner case 20, the movement of the first boss 21a in the rotation direction is restricted by the first boss receiving groove 10a of the outer case 10, and the second boss 22a is moved as shown in FIG. The rotary body 30 is engaged with the second boss receiving groove 31b and moves to the terminal position. That is, the inner case 20 is moved to the front side by the rotating body 30, and becomes the state of FIG.

In addition, when the rotating body 30 is rotated to the right in front view, the rotating body guide groove 31a of the rotating body 30 is engaged with the outer case guide 10b of the outer case 10, as shown in FIG. Therefore, the rotating body 30 rotates without moving in the axial direction with respect to the outer case 10. At this time, in the inner case 20, the movement of the first boss 21a in the rotation direction is restricted by the first boss receiving groove 10a of the outer case 10, and as shown in FIG. The rotating body 30 is engaged with the second boss receiving groove 31b and moves to the bending point. That is, the inner case 20 is moved to the rear surface side by the rotating body 30 to be in the state of FIG.
By switching between the states shown in FIGS. 6A and 6B, the amount of protrusion of the inner case 20 changes as shown in FIG. By rotating the rotating body 30, the inner case 20 can be moved up and down on the front side and the back side.

[Action]
Next, the operation of the electronic device 1 will be described.
FIGS. 8A and 8B are diagrams showing states before and after the rotation position of the rotating body 30 in the electronic device 1 is changed. FIGS. 8A and 8B show the rotating body 30 rotated to the left in front view. 8 (C) and FIG. 8 (D) show a case where the rotating body 30 is rotated right in a front view.
The electronic device 1 includes a sensor 20b on the back surface side, and the sensor 20b is in close contact with a living body when detecting biological information. On the other hand, when the sensor 20b is always kept in close contact with the living body, the user wearing the electronic device 1 is given a feeling of oppression. Therefore, the sensor 20b is worn with a certain margin except when detecting biological information.
Specifically, in the electronic device 1, except when the biological information is detected, as shown in FIGS. 8A and 8B, the rotating body 30 is rotated left in a front view, and the second boss is rotated. By locating 22a at the end position of second boss receiving groove 31b, inner case 20 is moved to the front side with respect to outer case 10.
As a result, the inner case 20 is pulled into the outer case 10, and the user can mount the electronic device 1 with a sufficient margin between the inner case 20 and the wrist.

On the other hand, in the electronic device 1, when the biological information is detected, as shown in FIGS. 8C and 8D, the rotating body 30 is rotated to the right in front view, and the second boss 22a is received by the second boss receiving portion. The inner case 20 is moved to the back side with respect to the outer case 10 by being positioned at the bending point of the groove 31b.
Accordingly, the inner case 20 projects from the outer case 10 to the back side, and the electronic device 1 can be mounted with the sensor 20b in close contact with the user's wrist.
At this time, the amount of protrusion of the inner case 20 from the outer case 10 can be adjusted by the amount of rotation of the rotating body 30.

As described above, in the electronic device 1 according to the present embodiment, the inner case 20 that engages with the outer case 10 and the rotating body 30 projects from the outer case 10 in conjunction with the rotation of the rotating body 30 with respect to the outer case 10. Or it is drawn into the outer case 10.
Therefore, the sensor 20b installed on the back surface of the inner case 20 (the surface facing the living body at the time of mounting) can be brought into close contact with the living body or released from the close contact by a simple operation.
Therefore, in a wearable electronic device that measures biological information, convenience can be improved.

Further, by rotating the rotating body 30 without touching the inner case 20 including the sensor 20b, the sensor 20b can be brought into close contact with the living body.
Further, it is possible to operate the rotating body 30 while visually recognizing the display 20a installed on the front side of the inner case 20.
In addition, by setting the shape of the second boss receiving groove 31b of the rotating body 30, the amount of rotation of the rotating body 30 and the amount of protrusion of the inner case 20 can be flexibly set. The configuration can be adapted to the user of the device 1.
In addition, since the rotation position of the rotating body 30 can be stopped at an arbitrary position, the protrusion amount of the inner case 20 can be appropriately adjusted with respect to the variation in the mounting state of the electronic device 1 among the users.

[Modification 1]
In the above-described embodiment, as shown in FIG. 6, the second boss receiving groove 31 b is bent at the bending point on the inner peripheral surface of the inner cylindrical portion 31 after extending in the generatrix direction from the end on the back surface side. The description has been given assuming that the terminal extends in the circumferential direction while approaching the front end to the end position in the middle of the peripheral surface. On the other hand, the configuration of the second boss receiving groove 31b may be another configuration as long as the inner case 20 is moved in the axial direction in conjunction with the rotation of the rotating body 30.
FIG. 9 is a schematic diagram illustrating another configuration example of the second boss receiving groove 31b.
As shown in FIG. 9, the configuration of the second boss receiving groove 31 b includes, on the inner peripheral surface of the inner cylindrical portion 31, a straight portion 311 b extending from the rear end to a bending point in the generatrix direction, and a bent portion from the straight portion 311 b. In addition, a configuration including an oblique portion 313b extending in the circumferential direction while approaching the end portion on the back surface side up to the terminal position in the middle of the inner peripheral surface can be adopted.

In the case of such a configuration, contrary to the configuration of FIG. 6, when the rotating body 30 is rotated to the left in front view, the inner case 20 is moved to the back side, and the rotating body 30 is moved to the right in front view. When rotated, the inner case 20 is moved to the front side.
Even in the case of such a configuration, the sensor 20b installed on the back surface of the inner case 20 (the surface facing the living body at the time of mounting) can be brought into close contact with the living body or released from the close contact by a simple operation. it can.
Therefore, in a wearable electronic device that measures biological information, convenience can be improved.

[Modification 2]
In the above-described embodiment, the second boss receiving groove 31b has been described as having a configuration in which the second boss 22a can be continuously moved from the bending point to the end position. On the other hand, the configuration of the second boss receiving groove 31b can increase the resistance at a predetermined position against the movement of the second boss 22a.
FIG. 10 is a schematic diagram showing a configuration example in which a step S for increasing resistance to the movement of the second boss 22a is provided at a predetermined position of the second boss receiving groove 31b.
In the configuration shown in FIG. 10, a predetermined number of steps S are provided on the side surface of the second boss receiving groove 31b. The height of the step S is set to be smaller than the radius of the second boss 22a, and when the second boss 22a is pressed against the step S by rotating the rotating body 30, the second boss 22a removes the step S. It is configured to get over.

With such a configuration, when the second boss 22a moves in the second boss receiving groove 31b, a certain resistance is given to the step S, and the rotation of the rotating body 30 at the position of the step S is easily stopped. can do.
That is, at the position corresponding to the step S of the second boss receiving groove 31b, the movement of the inner case 20 in the axial direction can be easily stopped, and the steps can be set to the extent that the electronic device 1 is brought into close contact with the living body. It becomes possible.
Although FIG. 10 illustrates the case where the step S is provided on one side surface of the second boss receiving groove 31b, the step S is provided on both side surfaces of the second boss receiving groove 31b. Is also good.
In this case, even when the rotating body 30 is rotated in any rotation direction, the rotation of the rotating body 30 can be easily stopped at the position of the step S.

[Modification 3]
In the above-described embodiment, the second boss 22a directly contacts the side surface of the second boss receiving groove 31b, and the second boss 22a can slide continuously from the bending point to the end position. It has been described as having a configuration. On the other hand, a configuration in which a bearing and an elastic body (such as a coil spring) are interposed between the second boss 22a and the second boss receiving groove 31b, and the elastic body biases the bearing toward the second boss receiving groove 31b. It can be. Then, by providing a concave portion in which a part of the bearing is fitted at a predetermined position on the side surface of the second boss receiving groove 31b, the resistance to the movement of the second boss 22a at a predetermined position can be increased. it can.

FIG. 11 is a schematic diagram showing a configuration in which a bearing B and an elastic body C are interposed between the second boss 22a and the second boss receiving groove 31b, and a concave portion is provided on a side surface of the second boss receiving groove 31b. .
In the configuration shown in FIG. 11, a bearing B is rotatably held by the second boss 22a, and the bearing B is urged toward the second boss receiving groove 31b. Further, a predetermined number of recesses H that fit into a part of the bearing B are provided on the side surface of the second boss receiving groove 31b.
In such a configuration, when the second boss 22a moves in the second boss receiving groove 31b, a fixed resistance is given by fitting the bearing B into the concave portion H, and the second boss 22a rotates at the position of the concave portion H. The rotation of the body 30 can be easily stopped.

[Modification 4]
In the above-described embodiment, a protrusion may be provided on the side surface on the end position side adjacent to the bending point of the second boss receiving groove 31b so as to resist the movement of the second boss 22a toward the bending point.
FIG. 12 is a schematic diagram illustrating a configuration example in which a projection P is provided on a side surface on the end position side adjacent to the bending point of the second boss receiving groove 31b.
In such a configuration, when the inner case 20 is assembled to the rotating body 30, after the second boss 22a is engaged with the second boss receiving groove 31b, the rotation of the rotating body 30 causes the second boss 22a to rotate. Even when the second boss 22a moves to the bending point, the second boss 22a can be prevented from returning to the bending point by contacting the projection P.
Therefore, it is possible to prevent the second boss 22a from coming off the second boss receiving groove 31b.

The electronic device 1 configured as described above includes the outer case 10, the inner case 20, and the rotating body 30.
The outer case 10 has an inner peripheral surface.
The inner case 20 is inserted into the outer case 10.
The rotator 30 engages with the inner case 20 and is provided rotatably with respect to the outer case 10. The rotator 30 moves the inner case 20 vertically along the inner peripheral surface of the outer case 10 in conjunction with the rotation. You.
As a result, the inner case 20 engaged with the rotating body 30 projects from the outer case 10 or is drawn into the outer case 10 in conjunction with the rotation of the rotating body 30 with respect to the outer case 10.
Therefore, the sensor 20b for measuring biological information installed on the back surface (mounting surface) or the like of the inner case 20 can be brought into close contact with the living body or released from the close contact by a simple operation.
Therefore, in a wearable electronic device that measures biological information, convenience can be improved.

The rotating body 30 and the inner case 20 are provided on the second boss receiving groove 31b provided on the inner circumferential surface of the rotating body 30 and on the outer circumferential surface of the inner case 20 corresponding to the inner circumferential surface of the rotating body 30. And the second boss 22a.
One of the second boss receiving groove 31b and the second boss 22a is a convex portion, and the other of the second boss receiving groove 31b and the second boss 22a includes a first groove portion extending obliquely.
Accordingly, the second boss 22a moves in the first groove (the second boss receiving groove 31b) in conjunction with the rotation of the rotating body 30, and the inner case 20 is moved along the central axis to the front side or It can be moved to the back side.

[Constitution]
FIG. 13 is a schematic diagram for explaining the back surface of the electronic device 1 according to the second embodiment.
The electronic device 1 of the present embodiment is configured as, for example, a wrist-type electronic device mounted on a wrist, similarly to the electronic device 1 of the above-described first embodiment. It has.
In the electronic device 1 of the present embodiment, light is irradiated to a blood vessel whose light reflectance and absorptivity repeatedly change periodically with the heartbeat and pulse periodicity, and the light is reflected from the blood vessel. A method of detecting a change in light and measuring a pulse waveform (pulse wave) (hereinafter, referred to as a “photoelectric artery method”) is employed.

  When the electronic device 1 of the present embodiment is viewed from the rear of the main body 2, as shown in FIG. 13A, a sensor mechanism 100 is provided at a central portion, and a holding mechanism 200 is provided around the sensor mechanism 100.

The sensor mechanism 100 is a mechanism that senses a blood flow state of a blood vessel in a wrist of a human body to be worn.
The sensor mechanism 100 includes a light receiving sensor unit 100A at the center and four LED (Light Emitting Diode) light emitting units 100B arranged concentrically so as to surround the light receiving sensor unit 100A.

The light receiving sensor unit 100A is configured to be able to receive light emitted from the LED light emitting unit 100B and reflected.
As shown in FIG. 13B, a light receiving glass 100C made of transparent glass and a lens 100D behind the light receiving glass 100C are provided on the human body contact surface side (front surface side) of the light receiving sensor unit 100A.

Further, a cover glass 100E made of transparent glass is provided on the human body contact surface side (front surface side) of the LED light emitting unit 100B.

Here, a sensing method in the sensor mechanism 100 will be described.
FIG. 14 is a schematic diagram for explaining a sensing method in the sensor mechanism 100.
As shown in FIG. 14, the sensing method in the sensor mechanism 100 is such that in a state of being pressed against the skin, the LED light emitting unit 100B emits light, irradiates the light to the surface of the skin to be measured, and reflects the light hitting the capillary. Is received as an optical signal by the light receiving sensor unit 100A receiving the light via a lens. The acquired optical signal is measured / recorded as a state of blood flow from a capillary by replacing the optical signal with an electrical signal corresponding to a pulse waveform.
In the sensor mechanism 100, a predetermined time (120 seconds in the present embodiment) is set as a measurement time in order to measure a pulse waveform.
The measurement result of the state of blood flow from the capillaries is output by analyzing the measurement result, for example, as a heart rate or pulse rate, stress / relaxation, drowsiness, sleep depth, arterial blood oxygen saturation, and the like.

  The holding mechanism 200 is protruded toward the wrist and pressed against the skin between the band 3 so as to prevent displacement (prevention of slippage) from the measurement site when the wrist is worn and to maintain pressure on the skin on the back surface of the main body 2. This is a mechanism for maintaining the pressed state during measurement. That is, the holding mechanism 200 has a holding function that operates so that the sensor mechanism 100 and the user's body change between the non-pressed state and the pressed state by moving the sensor mechanism 100 in the main body 2. As shown in FIG. 13A, the holding mechanism 200 is formed over the entire periphery outside the sensor mechanism 100 in order to uniformly press the back surface of the main body 2.

  Further, as shown in FIG. 13B, the holding mechanism 200 includes a pressing form 200A, a displacement device 200B located behind the pressing form 200A, and a compliance cover 200C located on the front surface of the pressing form 200A. Consists of

  The pressurizing form 200A is a ring body having a rounded tip, and by displacing the position, the pressurization of the main body 2 to the skin and the release of the pressurized state are enabled. In the present embodiment, the pressure foam 200A is formed of a material such as hard rubber or hard plastic.

  The displacement device 200B is a device that moves the pressurized form 200A in the crimping direction and causes the pressurized form to protrude. In the present embodiment, the eight displacement devices 200B are constituted by piezo-type actuators composed of stacked piezo structures, and are arranged concentrically at equal intervals. Note that the number of the displacement devices 200B may be increased or decreased.

  The compliance cover 200C is formed so as to cover the pressing foam 200A from the front side, is capable of coping with a bulge due to a displacement of the position of the pressing foam 200A, and is configured to be elastically deformable so as to reduce the burden on the skin. In the present embodiment, the compliance cover 200C is formed of a material having excellent elasticity such as a polymer material such as flexible rubber or resin, or a fiber material such as fabric.

Here, a method of pressing the skin to the holding mechanism 200 will be described.
FIG. 15 is a schematic diagram for explaining a method of crimping the skin to the holding mechanism 200.
As shown in FIG. 15 (A), the pressure applying method to the skin by the holding mechanism 200 applies a voltage to the displacement device 200B at the time of measurement so that the displacement device 200B expands to the skin side, and the pressure form 200A is pressed. The position is displaced so as to be pushed down to the skin side. With the displacement of the position of the pressure form 200A, the compliance cover 200C is deformed, pressed against the skin side, and brought into a state of being pressed against the skin.
Further, by stopping the application of the voltage of the displacement device 200B upon completion of the measurement, the displacement device 200B expands and contracts in the opposite direction to the skin side as shown in FIG. The position is displaced so that the compliance cover 200C is pushed up in the opposite direction, the pressing of the compliance cover 200C against the skin is released, and the crimped state on the skin is released.
In the present embodiment, the application of the voltage by the displacement device 200B is performed 10 seconds before the predetermined time so that the crimping state is obtained at the timing of the measurement.
In addition, the sensor mechanism 100 may be configured to be movable up and down with respect to the holding mechanism 200, so that the displacement device 200B is installed on the back surface, and the sensor mechanism 100 is displaced and pressed against the user's skin. good.

  In the electronic device 1, the friction between the compliance cover 200C and the skin is increased by being pressed against the skin, and even when a large vibration is applied, the sensor mechanism 100 (the light receiving sensor unit 100A and the LED light emitting unit 100B) and the skin may be in contact with each other. Is always maintained, thereby improving the measurement accuracy.

In addition, in the electronic device 1 of the present embodiment, a single measurement can be performed, but the measurement is performed at predetermined intervals.
Specifically, the measurement is performed at intervals of, for example, once every 30 minutes over time. In this case, the application of the voltage by the displacement device 200B is started 10 seconds before the measurement timing arrives, and the measurement is completed after a measurement time of 120 seconds. That is, when the measurement is performed once every 30 minutes, the measurement start time (the voltage at the displacement device 200B) is 30 minutes after the measurement start time (10 seconds after the application of the voltage at the displacement device 200B). 10 seconds after the application of is applied.

[Operation flow]
FIG. 18 is a flowchart illustrating a flow of a measurement process performed by the electronic device 1 in FIG. 16 having the functional configuration in FIG. 17.
The measurement process is started by a user's operation on the input unit 56 to start the measurement process. The measurement management unit 81 manages the measurement timing with reference to the measurement management information stored in the measurement management information storage unit 91. In the present embodiment, management is performed such that measurement is performed at 30-minute intervals for a predetermined period.

  In step S11, the measurement management unit 81 operates a measurement timer.

In step S12, the measurement management unit 81 determines whether or not the measurement time is 10 seconds before the voltage is applied to the displacement device 200B.
If the measurement time is before 10 seconds, YES is determined in step S12, and the process proceeds to step S13.
On the other hand, if the measurement time is not 10 seconds before, NO is determined in step S12, and the process returns to step S11.

  In step S13, the measurement management unit 81 starts up the system.

  In step S14, the displacement control unit 82 controls so as to apply a voltage to the displacement device 200B. As a result, the displacement device 200B is deformed, the pressure form 200A and the like are raised, and the main body 2 is pressed against the skin.

In step S15, the measurement management unit 81 determines whether the measurement start time has come.
If the measurement start time has not been reached, NO is determined in step S15, and the process enters a standby state in step S15.
On the other hand, when the measurement start time has come, YES is determined in step S15, and the process proceeds to step S16.

  In step S16, the measurement control unit 83 controls the LED light emitting unit 100B to start light emission.

  In step S17, the measurement control unit 83 controls the light receiving sensor unit 100A so as to start receiving light.

  In step S18, the measurement control unit 83 controls the light receiving sensor unit 100A to execute various signal processing such as light receiving signal conversion. As a result, the optical signal is converted into an electrical signal, and the measurement result of the pulse waveform is stored in the measurement result storage unit 92.

In step S19, the measurement management unit 81 determines whether it is time to complete the measurement.
If it is time to complete the measurement, YES is determined in step S19, and the process proceeds to step S20.
On the other hand, if it is not time to complete the measurement, NO is determined in step S19, and the process returns to step S18.

As a result, the displacement device 200B is deformed, the bulge due to the pressurized foam 200A or the like is released, and the pressure bonding of the main body 2 to the skin is released.

In step S23, the measurement management unit 81 determines whether to stop the continuous measurement.
If the continuous measurement is not stopped, NO is determined in step S23, and the process returns to step S11.
On the other hand, if the continuous measurement is to be stopped, YES is determined in step S23, and the measurement process ends.

In such an electronic device 1, a timing at which a pulse waveform (or a heartbeat waveform) is to be measured is identified and operated. The measurement may be automatically performed by a predetermined trigger, or may be manually performed by instructing the measurement by a user.
In the electronic device 1 of the present embodiment, when the measurement timing comes, pressure is automatically applied to the skin to be measured, and the holding mechanism 200 that presses the skin so that the positional relationship between the sensor mechanism 100 and the skin is stable and does not move easily. It has. The holding mechanism 200 enables stable measurement of the pulse waveform.
For this reason, in the electronic device 1, since the crimping is released outside of the measurement time period, the user does not have any discomfort during wearing out of the measurement time period, and the risk of stuffiness and rash is reduced. Will also have. Therefore, in the electronic device 1, convenience can be improved.

[Modification 1]
In the embodiment described above, the position of the holding mechanism 200 can be changed to the vicinity of the light receiving sensor unit 100A and the LED light emitting unit 100B.
FIG. 19 is a schematic diagram for explaining the electronic device 1 according to the first modification of the second embodiment.
In this example, as shown in FIG. 19, the holding mechanism 200 (the pressurizing form 200A, the displacement device 200B, and the compliance cover 200C) is arranged near the light receiving sensor unit 100A inside (inner circumference) of the LED light emitting unit 100B. .
Since the holding mechanism 200, which is a structure for preventing slippage by performing pressure bonding to the skin, is located closer to the light receiving sensor unit 100A and the LED light emitting unit 100B, the influence of vibration may be further eliminated.
Also, by arranging the LED light emitting unit 100B inside (inner circumference) near the light receiving sensor unit 100A, light leaks from the LED light emitting unit 100B to the light receiving sensor unit 100A from the space without passing through the skin and enters the light receiving sensor unit 100A. The effect of shutting down the leaked light beam and suppressing the noise component of the signal can be expected.

[Modification 2]
In the above-described embodiment, the pressure at the time of pressure bonding can be sensed, and an optimum measurement can be performed according to the pressure bonding level.

  In the present example, a pressure sensor (not shown) such as a piezo sensor is provided on the back surface of the pressure form 200A. The pressure applied to the pressurized foam 200A makes it possible to estimate the degree of adhesion to the skin. It is determined whether appropriate measurement can be performed based on the degree of adhesion to the skin, and the displacement of the displacement device 200B is controlled, the light emission intensity of the LED light emitting unit 100B is controlled, or the user cannot perform appropriate measurement. Notification to the effect that the change of the measurement position is urged.

FIG. 20 is a schematic diagram for explaining a method of determining a pressure level.
As shown in FIG. 20A, when the output of the pressure sensor is high and a high pressure is detected, it is determined that the pressure bonding level is sufficiently strong, and the measurement is performed with the light emission intensity of the LED light emitting unit 100B as the standard intensity. Do.
Further, as shown in FIG. 20B, when the output of the pressure sensor is low and a low pressure is detected, the pressure is determined to be slightly weak, and the light emission intensity of the LED light emitting unit 100B is increased. Thereby, measurement accuracy can be ensured.
Further, as shown in FIG. 20C, when there is no output (or very low) of the pressure sensor and no pressure is detected (or a very low pressure is detected), it is determined that the pressure bonding is quite weak. Then, the measurement is stopped, a warning as shown in FIG. 20 (D) is displayed, and the user is prompted to confirm whether to perform the measurement again. The user can change the position or adjust the band 3 in response to the warning.

[Operation flow]
FIGS. 21 and 22 are flowcharts illustrating the flow of the measurement process in the second modification. Note that processing similar to that of the first embodiment in FIG. 18 is omitted. That is, steps S11 to S23 (except step S16) are the same as steps S41 to S44, step S52, and steps S54 to S60, and a description thereof will be omitted.

  In step S45, the measurement control unit 83 controls the pressure sensor so as to detect the pressure.

In step S46, the measurement control unit 83 determines the pressure bonding level from the detection result of the pressure sensor.
If the pressure bonding level is sufficiently strong, it is determined in step S46 that the pressure is sufficiently strong, and the process proceeds to step S47.

  In step S47, the measurement control unit 83 sets the LED light emission intensity of the LED light emitting unit 100B to “standard”. Thereafter, the process proceeds to step S52.

  On the other hand, if the pressure bonding level is slightly weak, it is determined to be "slightly weak" in step S46, and the process proceeds to step S48.

  In step S48, the measurement control unit 83 sets the LED light emission intensity of the LED light emitting unit 100B to “strong”. Thereafter, the process proceeds to step S52.

  On the other hand, if the pressure bonding level is quite weak, it is determined in step S46 that it is [very weak], and the process proceeds to step S49.

  In step S49, the measurement control unit 83 performs control to cancel the application of the voltage to the displacement device 200B. As a result, the displacement device 200B is deformed, the bulge due to the pressurized foam 200A or the like is released, and the pressure bonding of the main body 2 to the skin is released.

  In step S50, the measurement management unit 81 controls the output unit 57 to display a warning and a mounting guidance. As a result, a display as shown in FIG.

In step S51, the measurement management unit 81 determines a confirmation operation.
If the confirmation operation is OK, it is determined to be "OK" in step S51, and the process returns to step S44.
On the other hand, if the confirmation operation is canceled, it is determined to be [Cancel] in step S51, and the measurement process ends.

  In step S53, the measurement control unit 83 starts the LED light emitting unit 100B to emit light at the set intensity.

In such an electronic device 1, the higher the irradiation intensity is, the more advantageous for stable measurement, but the consumption of the battery becomes intense. Only when is small, the pulse intensity is measured by increasing the light emission intensity.
Therefore, the electronic device 1 can automatically perform an operation according to the crimping state while suppressing power consumption, and can perform measurement in an optimal state.

[Modification 3]
In the embodiment described above, the holding mechanism 200 (displacement device 200B) is assumed to be a device such as a piezo-type actuator as a mechanism for holding the skin, and is configured from the main body 2 side. A piezo pump that inflates and compresses the bag body disposed on the band 3 side is configured to be crimped as the holding mechanism 200 ′.

FIG. 23 is a schematic diagram for explaining the holding mechanism of the third modification.
As shown in FIG. 23, the holding mechanism 200 ′ includes a micropump main body 200′A, a pipe body 200′B, and a shrinkable bag 200′C.
In the holding mechanism 200 ′ configured as described above, when the measurement start time comes, the micropump main body 200′A is operated, and the pipe is inserted into the shrink bag 200′C provided on the band 3 side opposite to the main body 2. The fluid (or air) is sent through the body 200'B, and the deflation bag 200'C is inflated, so that the sensor mechanism 100 (the light receiving sensor unit 100A and the LED light emitting unit 100B) can be pressed against the skin.

Since the electronic device 1 of the present embodiment employs the photoelectric artery method, it is extremely vulnerable to vibration and misalignment, and if the optical axis is displaced by slight vibration, even if it is not a violent movement, Each time, the alignment (positional relationship) between the capillaries and the light emitting element / light receiving element is lost, and as a result, the waveform is greatly disturbed. Also, a signal that has been disturbed once has several seconds before it shifts to stable periodicity determination and returns. For this reason, when the photoelectric artery method is used, there are restrictions on use, such as a premise that the band 3 is worn tightly, and a premise that the band 3 is at rest during measurement. For example, in the case of a band-type product, measurement is generally stabilized by tightening the wearing. However, wearing it tightly on a daily basis is unpleasant for the user, and there is another problem such as stuffiness and rash.
However, in the electronic device 1 according to the present embodiment, stable measurement is realized by increasing the degree of pressure between the mechanical sensor and the skin only during the “time period for performing measurement”. At the same time, loosening during the non-measurement time period improves the user's feeling of wearing. Then, a pressure sensor is used to measure the degree of contact between the sensor and the skin relating to the stability of the measurement by using a pressure sensor, and the measuring means is varied thereby to improve the measurement stability when the degree of contact is insufficient.

In the above-described embodiment, the pressing mechanism with the user's body is configured to be changed by the holding mechanism 200. However, without using the holding mechanism 200, the sensor mechanism 100 (the light receiving sensor unit 100A and / or the LED light emitting unit) is used. The part 100B) itself may be provided with a mechanism similar to the holding mechanism 200 to be able to protrude and have a holding function.
Further, it may be configured to include the holding mechanism 200 and the sensor mechanism 100 having the holding function (the light receiving sensor unit 100A and / or the LED light emitting unit 100B).
