PROBLEM TO BE SOLVED: To reduce user's operation mistakes by making the shapes of keys used at the time of moving a cursor the shapes representing a direction in which the cursor is moved. SOLUTION: In the shapes of keys, a key (2) 202 has a shape showing an upward direction, a key (4) 204 has a shape showing a left direction, a key (6) 206 has a shape showing a right direction and a key (8) 208 has a shape showing a downward direction and they show the four vertical and horizontal directions and left and right directions of a telephone display screen 200 when the number input keys of an inputting part and keys that move a cursor are the same keys. An input switching controlling part discriminates whether it is a number inputting mode of a cursor inputting mode. In the case of the number inputting mode, a number corresponding to the number specified on each key is shown on the screen 200. In the case of the cursor inputting mode, the cursor is moved by the keys (2) 202, (4) 204, (6) 206 and (8) 208. Also, a key (5) 205 decides the current position of the cursor, acquires a character corresponding to the cursor position and shows an acquired character on the screen 200.
