Abstract

Abstract The talking device has an ordinary handset (1) as well as an input / output panel (10) which is constituted by placing a flat plate-like liquid crystal display unit (200) on a two-dimensional semiconductor optical position detector (100). In response to operation for designating a position upon the input/output panel (10) through a light pen (20), the device attains such functions as registering the names and telephone numbers of other persons, dialing or automatic dialing, image data communication accompanying the voice data, timepiece setting, and similar functions.
