PURPOSE:To perform dialing automatically only by inputting a telephone number, by connecting a dial driving device and a controller for controlling the angle and speed of rotation of the dial driving device to a rotary dial telephone set. CONSTITUTION:To a telephone set 1, a driving device 2 for dialing the dial is fixed with a band 3. When a telephone number or some telephone number stored corresponding to one of about 30 keys is inputted on a keyboard 6, a controller 5 outputs a control signal to the driving device 2, and a pulse motor 11 turns the dial 12 at an optional angle through a disk 13 and then turns the disk 13 synchronously with a returning speed by a spring incorporated in the dial 12, thereby sending a dial signal to a telephone circuit. |
