Patent

CA 2271211

A pen computer includes an elongated pen barrel having a writing end provided with a rotatable ball bearing that serves as a ballpoint writing tip. The pen barrel is adapted to be held on one hand for forming characters on a writing surface via the ball bearing. First and second encoding assemblies are mounted on the writing end of the pen barrel, encode movement of the ball bearing along X and Y directions, and generate X-axis and Y-axis drive signals corresponding to encoded movement of the ball bearing along the X and Y directions. A processor is configured to operate as a character recognition unit. The processor is disposed in the pen barrel, and is connected electrically to the first and second encoding assemblies to receive the X-axis and Y-axis drive signals therefrom. The processor identifies the characters formed on the writing surface via the ball bearing from the X-axis and Y-axis drive signals, and generates computer codes that are assigned to the characters identified thereby.
