<p>PURPOSE:To obtain a data transmitter which is easily mounted on a small-sized electronic apparatus, by inputting characters, numbers, etc. by a hand-written character input means using touch switches. CONSTITUTION:Each time a 16Hz signal is inputted to an address part 9 from a frequency divider 11, a general flow is started; and first, the time counting processing is executed, and an operating part 7 reads out time count data till then from a RAM6 and adds a prescribed value and stores the addition result in the RAM6 again, and it is displayed on a display part 3 if the clock mode is set. In case of the transmission mode, character data from a touch switch 2 is inputted to the RAM6, and data in the RAM6 is sent to a data converting part 14 and is transmitted to another electronic clock from a transmitting part 15. In case of the reception mode, transmission data from another electronic clock is received by a receiving part 12 and is converted to parallel data by a data converting part 13 and is written in the RAM6. Data in each mode is set to a register in the RAM6, and individual processings are executed by a microprogram in a ROM5.</p> |
