<p>PROBLEM TO BE SOLVED: To efficiently input numerals by a ten key by incorporating the ten key into a keyboard part. SOLUTION: A keyboard part 1a is provided with a keyboard 2 on the side of a display part 1b. Further, a slide pad (mouse) 3 composed of a pad 3a and a click button 3b and a ten key 4 are laterally parallelly provided in front of this display part 1b. Besides, the ten key 4 is provided with a slide cover 5. Namely, when using the ten key 4, the slide cover 5 is opened and the ten key 4 is exposed but when not using the ten key 4, the slide cover 5 can be closed. It is preferable for space efficiency that the ten key 4 is arranged at a position parallel to the side of the slide pad 3. Thus, operation for inputting numerals through the ten key 4 can be performed simultaneously with operation for inputting sentences through the keyboard 2.</p> |
