Abstract

An electronic device is an electronic device that measures biological information. The electronic device includes a biological-information sensor section configured to measure the biological information and an armor case configured to house the biological-information sensor section. The armor case includes a case main body section and a rear lid section. One surface of the case main body section is integrally molded with a windshield and the other surface of the case main body section is formed of a transparent member in which an opening section is formed. The rear lid section is attached to the case main body section to close the opening section and at least a part of the rear lid section is formed of a transparent member.

Claims

1. An electronic device that measures biological information, the electronic device comprising:

a biological-information sensor section configured to measure the biological information; and

an armor case configured to house the biological-information sensor section, wherein

the armor case includes;

a case main body section; and

a rear lid section,

one surface of the case main body section is integrally molded with a windshield and the other surface of the case main body section is formed of a transparent member in which an opening section is formed, and

the rear lid section is attached to the case main body section to close the opening section and at least a part of the rear lid section is formed of a transparent member.

2. The electronic device according to claim 1, wherein the armor case is provided with a protector for blocking light to cover the case main body section excluding at least the windshield.

3. The electronic device according to claim 2, wherein the protector includes a first engaging section and a second engaging section for engaging the armor case and a band section.

4. The electronic device according to claim 1, further comprising a panel cover having a light transmission area smaller than the windshield in a projection view in a direction from the case main body section to the rear lid section.

5. The electronic device according to claim 1, wherein

the rear lid section further includes a detection window, and

the electronic device further comprises a light-guide control section configured to extend from the rear lid section to the case main body section and block light formed around the detection window.

6. The electronic device according to claim 1, wherein the rear lid section is formed by two-color molding.

7. The electronic device according to claim 5, wherein at least a part of the detection window is formed to project in a direction from the case main body section to the rear lid section.

8. The electronic device according to claim 1, wherein the biological-information sensor section includes a photoelectric sensor.

9. The electronic device according to claim 3, wherein

the band section includes:

a first band member and a second band member attached to a device main body of the electronic device; and

a coupling member provided at an end on an opposite side of the device main body in the first band member and configured to couple the first band member and the second band member,

at least one of the first band member and the second band member includes an expandable section configured to expand and contract along a band extending direction, which is an extending direction from the device main body, and

the expandable section includes;

a first fitting member located on the device main body side;

a second fitting member provided to be displaceable with respect to the first fitting member along the band extending direction; and

an urging member housed in the first fitting member and the second fitting member and configured to urge the second fitting member in an opposite direction of the band extending direction.

10. The electronic device according to claim 9, wherein one of the first fitting member and the second fitting member includes a display section configured to display a displacement amount of the second fitting member.

11. The electronic device according to claim 9, wherein one of the first fitting member and the second fitting member includes a convex section formed along a displacement direction of the second fitting member.

12. The electronic device according to claim 9, wherein one of the first fitting member and the second fitting member is a male fitting member and the other is a female fitting member.

13. The electronic device according to claim 9, wherein the expandable section is configured to be pivotable around a fitting section between the device main body and the first fitting member.

14. The electronic device according to claim 9, wherein the expandable section includes a drawing spring.

15. The electronic device according to claim 9, wherein the device main body comes into contact with a human body and measures the biological information.

16. The electronic device according to claim 15, wherein the device main body includes a stopper configured to limit pivoting of the first fitting member with respect to the device main body.
