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 an outer edge of the case and an inner circumference of which a circumferential length is shorter than a circumferential length of the outer circumference, and an acceleration sensor that is provided in the case, in which the solar battery is disposed outside an outer edge of the acceleration sensor 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 that has an opening at a first side of the case;   a transparent plate that is provided at the opening;   a display that is provided in the case and has a display region;   a plurality of solar cells that are provided between the transparent plate and the display and along the display region in a plan view from a normal direction to the display region;   a sensor substrate that is provided in the case and supports a pulse wave sensor, wherein the pulse wave sensor measures a pulse rate and does not overlap the plurality of solar cells in the plan view, and the display is provided among the plurality of solar cells and the sensor substrate;   a measurement window that is provided at a second side of the case, opposite the first side, wherein a transparent cover is provided at the measurement window, and the pulse wave sensor is provided between the sensor substrate and the transparent cover;   a circuit board that supports an acceleration sensor, an azimuth sensor, and a processor, and is provided between the display and the sensor substrate in the plan view, the acceleration sensor overlapping the display in the plan view; and   a secondary battery that is electrically connected to the solar battery and is provided between the sensor substrate and the circuit board and overlaps the acceleration sensor and the pulse wave sensor in the plan view.   
     
     
         2 . The portable electronic apparatus according to  claim 1 , wherein
 the circuit board has a first surface and a second surface opposite the first surface, and the first surface supports the acceleration sensor, the azimuth sensor, and the processor, and   a distance among the plurality of solar panels and the first surface is shorter than a distance from the sensor substrate to the second surface.   
     
     
         3 . The portable electronic apparatus according to  claim 1 , wherein
 each of the plurality of solar cells has an annular shape.   
     
     
         4 . The portable electronic apparatus according to  claim 2 , wherein
 each of the plurality of solar cells has an annular shape.   
     
     
         5 . The portable electronic apparatus according to  claim 1 , further comprising
 a circuit case that supports the circuit board and is provided between the case and an edge of the circuit board in a sectional view.   
     
     
         6 . The portable electronic apparatus according to  claim 3 , further comprising
 a circuit case that supports the circuit board and is provided between the case and an edge of the circuit board in a sectional view.   
     
     
         7 . The portable electronic apparatus according to  claim 5 , wherein
 the circuit case contacts with and guides the secondary battery.   
     
     
         8 . The portable electronic apparatus according to  claim 6 , wherein
 the circuit case contacts with and guides the secondary battery.
