Claim of US Patent No. 11,032,909

1. An electronic apparatus comprising:a first wiring board that has a first front surface and a first rear surface opposite the first front surface;
a second wiring board which differs from the first wiring board;
a biosensor that is mounted on the first front surface of the first wiring board and is to detect biological information;
an A/D converter unit that is mounted on the first rear surface of the first wiring board and converts an analog signal corresponding to the biological information detected by the biosensor to a digital signal;
a signal processing unit that is mounted on the second wiring board and takes input of the digital signal which has been output from the A/D converter unit and processes that signal;
a wireless communication unit that is mounted on the second wiring board and is electrically coupled to the signal processing unit; and
an antenna that is mounted on the second wiring board and is electrically coupled to the wireless communication unit,
wherein the biosensor is a pulse wave sensor,
wherein a temperature sensor is mounted on the first front surface of the first wiring board and detects bodily temperature of a living body, and
wherein the height of the pulse wave sensor from the first front surface is higher than the height of the temperature sensor from the first front surface to allow the pulse wave sensor to be in contact with the living body,
wherein the electronic apparatus is configured to be attached to an eyeglass frame,
wherein the eyeglass frame is disposed between the first rear surface of the first wiring board and the second wiring board,
wherein a rechargeable battery is disposed between the eyeglass frame and the second wiring board,
wherein the second wiring board includes a second front surface and a second rear surface opposite the second front surface,
wherein the second front surface includes a first area and a second area,
wherein the antenna is mounted in the first area, and
wherein the rechargeable battery is disposed so as not to overlap with the first area of the second front surface.
