Abstract
Letter input rate of a conventional cell phone is low because only thumb is used for inputting a letter. When the inventive cell phone provided with one joystick, two shift keys and twenty six keys on the opposite side faces is grasped by both hands and ten fingers are used, any one of twenty six alphabetical letters can be inputted by single push operation without switching the shift key and letters can be inputted at super-high rate by touch typing. A novel and epoch-making field as the communication means of a cell phone is developed and convenience of user can be enhanced significantly.
