<p>A pen computer (1) includes an elongated pen barrel (10) having a writing end provided with a rotatable ball bearing (15) that serves as a ballpoint writing tip (16). The pen barrel (10) is adapted to be held on one hand for forming characters on a writing surface via the ball bearing (15). First and second encoding assemblies (2, 2') are mounted on the writing end of the pen barrel (10), encode movement of the ball bearing (15) along X and Y directions, and generate X-axis and Y-axis drive signals corresponding to encoded movement of the ball bearing (15) along the X and Y directions. A processor (33) is configured to operate as a character recognition unit (331) . The processor (33) is disposed in the pen barrel (10), and is connected electrically to the first and second encoding assemblies (2, 2') to receive the X-axis and Y-axis drive signals therefrom. The processor (33) identifies the characters formed on the writing surface via the ball bearing (15) from the X-axis and Y-axis drive signals, and generates computer codes that are assigned to the characters identified thereby. <IMAGE></p> |
