Abstract
In a data communication apparatus having an abbreviated dialing function, data referred to when performing abbreviated dialing is prevented from vanishing in the event of a malfunction or power failure. This is achieved by providing the apparatus with an internal non-volatile storage device in addition to a memory which stores information referred to when communicating with another party. The information which has been stored in the memory is preserved in the non-volatile storage device. If the information in the memory vanishes, the preserved information is restored by being loaded into the memory from the non-volatile storage device.
Claims66
A communication apparatus comprising:
- a rewritable volatile memory for storing a plurality of addresses;
- manual selecting means for manually selecting one of the addresses stored in said volatile memory;
- transmitting means for transmitting data to the selected address;
- a non-volatile storage device for storing the data to be transmitted by said transmitting means;
- preserving means for preserving the plurality of addresses and the data which have been stored with a predetermined file name to be distinguishable from other data stored therein;
- and
- reading means for reading the plurality of addresses, which has been preserved by said preserving means, out of said non-volatile storage device and storing the plurality of addresses into said volatile memory.
