Portable electronic apparatus

Abstract

A wrist apparatus includes a case, a solar battery that is provided in the case, and an optical sensor unit as a biological information measurement unit that is provided in the case, measures biological information, and is disposed at a position overlapping the solar battery in a plan view of a light reception surface of the solar battery.

What is claimed is: 
     
         1 . A portable electronic apparatus comprising:
 a case having an opening;   a plate covering the opening;   a display panel disposed in the case;   a solar battery disposed between the plate and the display panel in the case and around the display panel in a plan view;   a biological information measurement unit that is disposed in the case on an opposite side of the display panel from the solar battery, measures biological information, and is disposed at a position overlapping the solar battery in the plan view; and   a circuit board that is provided in the case, and is electrically connected with the display panel, the solar battery, and the biological information measurement unit,   wherein a distance between the circuit board and the solar battery is shorter than a distance between the circuit board and the biological information measurement unit in a sectional view from a direction which is orthogonal to a normal direction to a light reception surface of the solar battery.   
     
     
         2 . The portable electronic apparatus according to  claim 1 , further comprising:
 a secondary battery disposed between the display panel and the biological information measurement unit in the case, and that is electrically connected to the solar battery.   
     
     
         3 . The portable electronic apparatus according to  claim 1 , wherein the portable electronic apparatus has a region in which the solar battery, the display panel, and the biological information measurement unit overlap each other in the plan view. 
     
     
         4 . The portable electronic apparatus according to  claim 1 ,
 wherein the biological information measurement unit includes a measurement window portion provided in the case, and   the measurement window portion is disposed at a position overlapping the solar battery in the plan view.   
     
     
         5 . The portable electronic apparatus according to  claim 1 ,
 wherein the circuit board has a first surface and a second surface which is different from the first surface, and   the solar battery is connected to the first surface, and the biological information measurement unit is connected to the second surface.   
     
     
         6 . The portable electronic apparatus according to  claim 5 , further comprising:
 an illumination unit that illuminates the display panel,   wherein the illumination unit is connected to the first surface of the circuit board.   
     
     
         7 . The portable electronic apparatus according to  claim 1 ,
 wherein the biological information measurement unit includes a light emitting portion, a light receiving portion, and a sensor substrate that supports light emitting portion and the light receiving portion, and   the sensor substrate overlaps with the solar battery.
