Transmitter device having means for automatically transmitting data remaining therein upon its re-activation

A transmitter device comprising:

• a power source for activating the transmitter device;
• input means for inputting a request signal;
• first control means formulating data to be transmitted based on the request signal, the first control means including a memory device which is able to memorize the request signal therein as a backup request signal even when a power source becomes unable to activate the transmitter device, the first control means eliminating the backup signal from the memory device upon completion of transmission of the data;
• second control means for formulating the data to be transmitted based on the backup request signal upon reactivation of the transmitter device if the backup request signal is still memorized in the memory device;
• and
• means for transmitting the data formulated in the first control means and in the second control means.
