ELECTRONIC PEN WITH RETRACTION MECHANISM AND FORCE SENSOR
First Claim
1. An electronic pen for interacting with a substrate having coded data disposed thereon, the pen comprising:
- an image sensor for sensing at least some of the coded data when the pen is used to interact with the surface;
a cartridge having a nib for contacting said surface;
a retraction mechanism for slidably moving said cartridge between a retracted position wherein said nib is retracted within a body of said pen and an extended position wherein said nib protrudes from said body;
a force sensor cooperating with said retraction mechanism, said force sensor being configured to sense a force applied to said surface by said nib when said nib is in said extended position;
a processor configured to generate, using at least some of the sensed coded data, indicating data indicative of the interaction with the substrate; and
communication means for communicating the indicating data to a computer system, wherein said image sensor is configured to sense said coded data only when said force sensor detects that said nib is in contact with said substrate.

Abstract
An electronic pen for interacting with a substrate having coded data disposed thereon. The pen comprises: an image sensor for sensing the coded data when the pen is used to interact with the surface; a cartridge having a nib for contacting the surface; a retraction mechanism for slidably moving the cartridge between a retracted position and an extended position; a force sensor cooperating with the retraction mechanism; a processor configured to generate indicating data indicative of the interaction with the substrate; and communication means for communicating the indicating data to a computer system. The image sensor is configured to sense the coded data only when the force sensor detects that the nib is in contact with the substrate.
