ABSTRACT:
In a portable measuring instrument using as a power source a group of solar batteries in which a plurality of solar batteries are series-connected on the same plane, respective light receiving windows are made to be substantially equal in area to one another, and each of the light receiving windows surrounds the outer periphery of other light receiving windows adjacent thereto, whereby, even if part of the light which irradiates the light receiving windows of the solar batteries is screened by a hand or other holding means for operating and holding the portable measuring instrument, it is avoided that only a specific light receiving window is screened, so that a current of the group of solar batteries can be efficiently produced.
