Abstract

An automatic dialing apparatus stores in a RAM an area code number, a local code number and a plurality of subscribers' telephone numbers in the area of the local code number thereof with hyphens for separating these numbers and telephone numbers from each other. It further displays a series of telephone numbers on a display portion in the apparatus in response to operation of a search key. When a local key is operated, a local code mark is detected, a local code number of digits higher than the local code mark is cancelled, and thus the telephone numbers of digits lower than the local code mark are displayed. Each time the local key is operated, the hyphens in the telephone numbers are searched for to be displayed. If a dial out key is operated when a desired telephone number is displayed, a tone signal corresponding to the desired telephone number is generated. Therefore, an arbitrary number can be selected from a series of numbers.
