PURPOSE:To simply and quickly correct a number at every digit by displaying a telephone number designated by a ten-key onto a display device and depressing a switch corresponding to a digit number to be corrected. CONSTITUTION:In operating a ten-key of a telephone set 2 to dial an opposite telephone number, a controller 1 stores a signal from the telephone set 2 in response to the operation of the ten-key into a memory 4 and displays the number based on the stored signal onto a display device 6. If the ten-key is depressed in error and the 3rd digit of the telephone number differes between the opposite telephone number and the display number, a switch 5-3 corresponding to the 3rd digit of the display device 6 is depressed, then the ten-key of the telephone set 2 is operated to output a signal corresponding to the correct number from the telephone set 2. Thus, said dialing controller can confirm the ten-key operation in error by the display device and can correct the number at every required digit.
