<p>PURPOSE:To eliminate difficulty to see at the time of key input due to the both display of the alphanumerics/KANA characters (Japanese syllabary) of a keyboard. CONSTITUTION:Characters displayed on the keys of a keyboard 2 are displayed on a keyboard protective cover 1 having a color which makes the characters of the keys to be unseen. The protective cover 1 is formed so that the upper face of the keyboard and the all keys can be covered, and either one of the KANA characters or the alphanumerics, are largely displayed on a display part 1a so that easiness to see can be improved.</p> |
