When there is an available function for inputting the number and the character, an input button for using the available function is displayed in the input result display area or in an adjacent area of the input result display area, while when there is no available function, the button is not displayed in the input result display area or in the adjacent area of the input result display area.
1. A display device for a data transmission apparatus that is configured to save a transmission history of data transmissions made thereby, said display device comprising:
an input unit that receives operation inputs;
a display unit that displays screens according to the operation inputs, the display unity displaying a destination input screen and a fax transmission destination input screen as screens provided with an input result display area reflecting an input of a transmission destination to the input unit by a user, the input result display area displaying an input result including at least a number and a character; and
a display control unit determining, at a time when the display unit starts display of the destination input screen and the fax transmission destination input screen, to cause the display unit to display a re-addressing button, in the input result display area or in an area adjacent to the input result display area, if the data transmission apparatus has saved the transmission history, and to cause the display unit to not display the re-addressing button if the data transmission apparatus has not saved the transmission history, the re-addressing button calling up an address of a previous data transmission within the transmission history.
2. A display device according to claim 1 , wherein when the re-addressing button is not displayed, the display unit displays other information about input instead of the re-addressing button.
3. An image forming apparatus comprising the display device according to claim 1 , the image forming apparatus being the data transmission apparatus and transmitting image data.
4. A method of displaying for a data transmission apparatus that is configured to save a transmission history of data transmissions made thereby, said display method comprising:
receiving operation inputs at an input unit;
displaying, by a display unit, screens according to the operation inputs, said displaying including displaying a destination input screen and a fax transmission destination input screen as screens provided with an input result display area reflecting an input of a transmission destination to the input unit by a user, the input result display area displaying an input result including at least a number and a character; and
controlling, by a display control unit, at a time when the display unit starts display of the destination input screen and the fax transmission destination input screen, the display unit to display a re-addressing button, in the input result display area or in an area adjacent to the input result display area, if the data transmission apparatus has saved the transmission history, and not to display the re-addressing button if the data transmission apparatus has not saved the transmission history, the re-addressing button calling up an address of a previous data transmission within the transmission history.
5. A displaying method according to claim 4 , wherein when the re-addressing button is not displayed, information about other input is displayed instead of the re-addressing button.
