Abstract
According to the present invention, a data transmission device that can transmit data to a destination contained in pre-stored destination information, the data transmission device comprises a determining section that, when the device is instructed to transmit data, determines whether or not destination information contained in the transmission instruction was updated after the last data transmission carried out with reference to the destination information; and a notifying section that, if the determining section determines that the destination information was updated after the last data transmission to the destination, notifies a user having given the transmission instruction that the destination information has been updated.
Claims12
A data transmission device that can transmit data to a destination contained in prestored destination information, the data transmission device comprising:
- a determining section that, when the device is instructed to transmit data, determines whether or not destination information contained in the transmission instruction was updated after the last data transmission carried out with reference to the destination information;
- and
- a notifying section that, if the determining section determines that the destination information was updated after the last data transmission to the destination, notifies a user having given the transmission instruction that the destination information has been updated.
A method for controlling data transmission using a data transmission device that stores, in a memory, destination information indicating a data destination, update time information indicating the last time when the destination information was updated, and transmission time information indicating the last time when data was transmitted to the destination, the pieces of information being associated with one another, the method comprising:
- a determining step of, when the data transmission device is instructed to transmit data, referring to the transmission time information and the update time information to determine whether or not destination information contained in the transmission instruction was updated after the last data transmission carried out with reference to the destination information;
- and
- a notifying step of, if the determining step determines that the destination information was updated after the last data transmission to the destination, notifying a user having given the transmission instruction that the destination information has been updated.
A data transmission device comprising:
- an address book database that stores destination information in association with destination identifiers;
- a determining section that, if any destination identifier is specified as a destination for data, determines whether or not destination information associated with the destination identifier was updated after the last data transmission with the destination identifier specified;
- and
- a notifying section that, if the determining section determines that the destination information was updated after the last data transmission with the destination identifier specified, notifies a user having specified the destination identifier that the destination information has been updated.
A program, stored on a computer readable medium, executable by a computer that stores, in a memory, destination information indicating a data destination, update time information indicating the last time when the destination information was updated, and transmission time information indicating the last time when data was transmitted to the destination, the pieces of information being associated with one another, the program allowing the computer to function as:
- a determining section that, when the computer is instructed to transmit data, refers to the transmission time information and the update time information to determine whether or not destination information contained in the transmission instruction was updated after the last data transmission carried out with reference to the destination information;
- and
- a notifying section that, if the determining section determines that the destination information was updated after the last data transmission to the destination, notifies a user having given the transmission instruction that the destination information has been updated.
