PURPOSE:To improve the identification characteristic and the operability of line wire incoming keys and dial keys. CONSTITUTION:The line wire incoming keys 2 are arranged on the external surface of an upper case 1, and a user sets the direction of the arranging surface of the line wire incoming keys 2 in a direction where the keys can always be recognized. When a line wire call arrives, the user captures a line wire by depressing the line wire incoming keys 2 which are set in the direction where they can be recognized so as to make the call. The keys (ten keys) 4 except for the line wire incoming keys are arranged on the external surface of a lower case 3. The direction of the arranging surface of the keys 4 is set in the direction where the user can recognize them and the call is made by depressing the keys 4 when the user makes the call. Since an area for arranging the keys and the intervals of the keys are larger compared to conventional ones in the same external size, the identification characteristic and the operability of the respective keys improve. |
