TrackWrite

TrackWrite is a separatable keyboard which is used by ThinkPad 701 series. It was developed to solve problems that minimize size of footprint and supply full-sized keyboard.

The mechanism is complicated and the cost seems to be high. So TrackWrite is only used by ThinkPad 701 series.

Now I'll show you a movement of TrackWrite.

If a display is opened, a keyboard will expand little by little and full-sized keyboard will appear finally.
