Abstract

A foldable type portable telephone capable of making a dial lock function effective with simple operations is provided. In the case where auto dial lock is set, when a control unit of the foldable type portable telephone determines that the telephone is in a wait state and furthermore when an opened state of an upper case and a lower case is detected by a case open/close detection mechanism, the control unit executes activation processing of an auto dial lock unit. When a timer detects that a setting time entered in auto dial lock setting has elapsed, the control unit controls the auto dial lock unit so that it activates dial lock processing for invalidating key entries except at least an entry of personal identification codes used for unlocking in the key operation unit. After this processing, the key operation unit in the foldable type portable telephone accepts only the key entry of personal identification codes.
