<p>PROBLEM TO BE SOLVED: To incorporate a palm rest part without increasing the size of a device in order to improve operability at the time of key input at a portable information processor such as a note-type personal computer. SOLUTION: This system is composed of a keyboard part 2, a main body 1 with the palm rest part 11 and a lid part 3 supported to the main body 1 in the state of being openable and closable. In addition the part 2 is supported to the main body 1 in the state of being slidably to allow the part 2 to take a first position exposing the part 11 at its front part when the part 3 is opened and to allow the part 2 to take a second position overlapping the part 11 at its lower part when the part 3 is closed.</p> |
