Abstract

PURPOSE:To obtain electronic equipment having commerical product value suitable for the cost of solar battery by providing a function as data input means in a sloar battery for charging a secondary battery disposed in electronic equipment. CONSTITUTION:When light is received on the solar battery 3a, 3b, the electromotive force is generated to charge the sencondary battey 6. The output voltage of the secondary battery 6 is impressed as an working voltage with respect to LSI 9 and display device 2. When operating the external operating switch 4, the output of flip flop 14 is reversed, and open AND circuit 15, 16. Under this condition, when the light strength signal is applied to the solar battery 3a, 3b, for the time correction, the correcting time data writing command signal is given to the counting circuit 12 and time is corrected. As the data externally given, alarm time data, telephone number, time table data, melody data etc. are empolyed.
