Portable electronic apparatus and wrist apparatus

Abstract

A wrist apparatus as a portable electronic apparatus includes a case, a solar battery that is provided in the case and has an outer circumference along the outer edge of the case and an inner circumference the perimeter of which is shorter than that of the outer circumference, and an acceleration sensor that is provided in the case and disposed in a position where the acceleration sensor overlaps with the solar battery in a plan view of light receiving surface of the solar battery.

What is claimed is: 
     
         1 . A portable electronic apparatus comprising:
 a case that has an opening at a first side of the case;   a glass plate that is arranged at the opening;   a display panel that is provided in the case and has a display area;   an annular solar battery that is provided among the glass plate and the display panel in the case, and is provided around the display area;   a circuit substrate having an outer circumference that is supported by the case;   an acceleration sensor mounted on the circuit substrate and disposed in a position where the acceleration sensor overlaps with the annular solar battery in the plan view;   a pulse wave sensor that includes a light emitter and a light receiver, and is provided on a sensor substrate, the circuit substrate is provided among the annular solar batter and the sensor substrate; and   a secondary battery provided among the circuit substrate and the sensor substrate and electrically connected to the annular solar battery,   wherein the acceleration sensor is disposed outside an outer edge of the pulse sensor.   
     
     
         2 . The portable electronic apparatus according to  claim 1 , further comprising:
 a measurement window that is provided at a second side opposite the first side; and   a transparent cover that is provided at the measurement window, wherein   the pulse wave sensor is provided among the sensor substrate and the transparent cover.   
     
     
         3 . The portable electronic apparatus according to  claim 1 , wherein
 the acceleration sensor is mounted on the circuit substrate and disposed in a portion facing the outer circumference of the circuit substrate.   
     
     
         4 . The portable electronic apparatus according to  claim 1 , wherein
 the circuit substrate has a first surface and a second surface so related to the first surface that the first and second surfaces are front and rear surfaces of the circuit substrate,   the acceleration sensor is provided on the first surface, and   a biological information measuring section that measures biological information is provided on the second surface.   
     
     
         5 . The portable electronic apparatus according to  claim 1 , wherein
 the second battery does not overlap with the acceleration sensor.   
     
     
         6 . The portable electronic apparatus according to  claim 1 , wherein
 the second battery does not overlap with the annular solar battery.   
     
     
         7 . The portable electronic apparatus according to  claim 5 , wherein
 the second battery does not overlap with the annular solar battery.
