CONSTITUTION:A half surface of the top surface of the data card 10 is formed into a solar battery 12 for a power source and the data entry part 14 which is sectioned into four stages vertically and eight stages laterally is formed in the lower half of the top surface of the card 10. Necessary parts of many small sections of the data entry part 14 are painted out to generate time information, which is processed as the electric signal in the card 10 and then transmitted as the serial light signal to the timer main body from the light emitting element 36.</p> |
