Embodiment 1 FIG.
FIG. 1 is an exploded view of a sensor unit 10 according to the first embodiment. The sensor unit 10 includes a case body 12. The case main body 12 includes a control board mounting part 14, a base part 15, and a sensor board mounting part 20. The base portion 15 includes a convex portion used for fitting with other members in addition to a substantially plate-shaped portion. A control board mounting portion 14 is provided on the base portion 15. An opening 16 is formed in the control board mounting portion 14. A sensor board mounting portion 20 is provided on a part of the control board mounting portion 14. The sensor board mounting portion 20 is a structure that stands upright with respect to the base portion 15 and the control board mounting portion 14. The sensor board mounting portion 20 has a cut portion 18 at the base portion. The length in the y direction of the sensor board mounting portion 20 is shortened in the portion where the cut portion 18 is present. The sensor board mounting portion 20 includes a support portion 20a. The support portion 20 a is a surface inclined with respect to the base portion 15.

  The control board 30 is a part that performs signal processing of the sensor unit 10 and the like. The control board 30 can include an arithmetic circuit that enables such signal processing. The control board 30 can be connected to the sensor board 50 by the harness assembly 40.

  The sensor substrate 50 includes a sensor used for external observation. The type of sensor is not particularly limited, and examples thereof include an infrared sensor for detecting a human body that detects a change in the amount of infrared energy, a human sensor such as a heat ray sensor or a radio wave sensor, a brightness sensor, or an image sensor.

  The cover 60 covers the contents of the sensor unit 10. The cover 60 has a protruding sensor cover portion 62. The sensor cover 62 is hollow.

  FIG. 2 is another exploded view of the sensor unit 10 according to the first embodiment. As shown in FIG. 2, the control board mounting portion 14 may be a quadrangular or annular frame, for example. The sensor board mounting part 20 can be provided on one side or a part of the control board mounting part 14. In other words, the sensor board mounting portion 20 can be provided at a position in the positive z direction of the control board mounting portion 14.

  The cover 60 has a facing surface 62 a that faces the sensor substrate 50. In the state after assembly, the facing surface 62a and the sensor substrate 50 can be substantially parallel. Thereby, a sensor detection range similar to that of the sensor substrate 50 alone is obtained.

  FIG. 3 is a perspective view of the case body 12 to which the control board 30 and the sensor board 50 are attached. The control board 30 is attached to the control board attachment portion described above. The control board 30 can be attached to the control board attachment portion 14 so as to cover the opening 16 of FIG.

The sensor substrate 50 is disposed obliquely with respect to the control substrate 30 above the control substrate 30. Specifically, the normal vector of the control board 30 extends in the positive z direction, but the normal vector of the sensor board 50 has a z component and a y component. Thus, the sensor surface of the sensor substrate 50 is not parallel to the control substrate 30 but is inclined. In this example, such an oblique arrangement is realized by the sensor substrate mounting portion 20 having a support portion 20a that is inclined with respect to the control substrate 30, and the sensor substrate 50 being attached to the support portion 20a. And the support part 20a supports the outer edge part along the outer edge of the sensor board | substrate 50, and exposes the center part of the sensor board | substrate 50, without supporting.

FIG. 5 is a perspective view of the sensor unit 10 after assembly when viewed from a different angle from that in FIG. 4. FIG. 6 is a front view, a side view, a plan view, and a bottom view of the sensor unit 10. From the front view, it can be seen that the sensor cover portion 62 does not protrude from the case body 12 and is provided in a form that avoids an increase in the area of the sensor unit 10.

  7 is a cross-sectional view taken along the alternate long and short dash line in FIG. It is illustrated that the sensor board 50 is disposed obliquely with respect to the control board 30 in the upper part of the control board 30 or in the positive z direction.

  In the sensor unit 10 according to the first embodiment, the control board 30 and the sensor board 50 can be easily fixed and stored in the case body 12. Further, by providing the sensor board mounting portion 20, the sensor board 50 can be held above the control board 30 at an angle with respect to the control board 30. Such a configuration enables the sensor substrate 50 to be stably fixed at a desired position, so that suitable sensing by the sensor can be realized.

For example, the sensor substrate 50 provided in the sensor unit 10 is attached obliquely to the decorative plate 72 parallel to the xy plane. FIG. 10 is a front view of FIG.

  FIG. 11 is a perspective view of an electronic device to which the cover 74 is attached. Since the cover 74 is attached on the sensor unit 10, it does not cover the sensor unit 10. 12 is a front view, a side view, a plan view, and a bottom view of the electronic apparatus of FIG. FIG. 13 is a side view of an electronic device whose inside is visualized. 14 is a cross-sectional view taken along one-dot chain line in FIG.
