ELECTRONIC PEN WITH RETRACTABLE NIB AND FORCE SENSOR
First Claim
1. An electronic pen having a retractable nib for interacting with a surface, said pen comprising:
- a slidably movable cartridge having a nib at a first end for contacting the surface, said cartridge being configurable in an extended position, wherein said nib protrudes from a body of said pen, and a retracted position wherein said nib is retracted in said body;
a retraction mechanism comprising;
a barrel for receiving an opposite second end of said cartridge, said barrel being adapted for seating said cartridge in either said extended position or said retracted position, whereby a longitudinal axial force from said cartridge is transmitted to said barrel in said extended position; and
a biasing mechanism for biasing said cartridge towards said extended or retracted positions;
an actuator coupled to said retraction mechanism, said actuator enabling a user to move said cartridge between said extended and retracted positions;
a force sensor coupled to said barrel, said force sensor providing a reaction to said axial force transmitted to said barrel from said cartridge; and
a processor configured for generating force data indicative of a force detected by said force sensor.

Abstract
An electronic pen having a retractable nib for interacting with a surface. The pen comprises a slidably movable cartridge having a nib for contacting the surface, a retraction mechanism for retracting the cartridge, an actuator coupled to the retraction mechanism, a force sensor providing a reaction to an axial force transmitted from the cartridge, and a processor configured for generating force data indicative of a force detected by the force sensor. The retraction mechanism comprises a barrel for receiving the cartridge, which is adapted for seating the cartridge in either an extended position or a retracted position, whereby the axial force from the cartridge is transmitted to the barrel in the extended position. A biasing mechanism biases the cartridge towards the extended or retracted positions.
