PROBLEM TO BE SOLVED: To provide a personal computer with protrusions for hand correction, which is quick and easy of operation, and that prevents slippage of hands so as to continue hitting keys, while setting viewpoint on a screen at all times, when using the personal computer, and also utilizes a tactile sense without depending on a visual sense for restoring a hand position, after hitting the keys at the edges. SOLUTION: By arranging small protrusions on a keyboard space 6 where the thickness parts of thumb bases of both palms contact, the small protrusions are always brought into contact with the same points of the palms, when the hands are in the correct positions, thereby storing the points with the tactile sense, after hitting the keys for a while. By means of this memory, slippage of hand will not be caused, and the hands can quickly be restored to the correct positions by the tactile sense, without moving the viewpoint from the screen, after having moved the hands.
