As shown in FIG. 3, the telephone number memory 7a has an area X for storing telephone numbers nl, n2, . . . designated by one-touch key operations or abbreviated dial key operations, and their related telephone numbers. Here, phone number n1. n2・
. . . is a multi-digit telephone number, which is stored from the first address xO, xl . . .

Conventionally, only telephone numbers are stored in the area starting from the first addresses xo, xi, etc., but in this embodiment, the telephone numbers nl, nl, nl, etc. are stored after each of the telephone numbers n1, n2, etc. (usually on the higher address side). Telephone numbers n1-1. associated with n2..., respectively. nl-2... are stored.

In area X, telephone numbers nl, n2... and related telephone numbers n1-1゜n1-2--
・and n2-1. n2-2- are areas each having a byte length ofst (address [AO]+ofst, [A
O]+2ofst...: [] indicates the contents of the pointer).

For example, phone number nl and its related numbers n1-1, nl
-2 is input continuously by an input process that assigns telephone numbers to known shortcut keys and one-touch keys, and
They are stored in order starting from address A within. At the end of the related telephone number storage area, an O indicating a data delimiter is stored between the next telephone numbers. It is assumed that the telephone number registration process is performed in the same manner as in the past, using the display as a monitor. In this case, the normal telephone number and the related telephone number shall be distinguished by a predetermined operation.
