Abstract

PURPOSE:To reduce the numbers of dividing of an element selecting the boosting ratio of a booster circuit and simplify the assembling of an electronic desk calculator by boosting the electric generating power of the element of a desk calculator provided with an electric power generation of an photoelectric conversion element as its energy source. CONSTITUTION:With electric generating power of a solar cell 21 consisting of an photoelectric conversion element as the energy source, a load circuit 24 of an electronic desk calculator is drived. A multivibrator in a booster circuit 22 is operated by the energy output from this cell, and the AC voltage generated by it is boosted by a transformer and rectified and supplied to the load circuit 24. And between the load circuit 24 and the booster circuit 22, a constant voltage element 23 is connected. Then, the numbers of dividing of the photoelectric element are reduced by selecting the boosting ratio of the booster circuit 22, the assembly of electric calculators is facilitated and application of the solar cell to a wrist watch etc. is simplified.
