Abstract
A roller ball pen ( ) that permits a user to adjust the bias force that biases a roller ball cartridge ( ) out of the pen ( ) to suit the user's particular writing style. The pen ( ) has a body ( ) having distal and proximal ends, a roller ball cartridge ( ) disposed in the body ( ), a cap ( ) removably disposed on the proximal end of the body ( ), a control member ( ) slidingly disposed in the cap ( ), a spring ( ) attached to the distal side of the control member ( ) and abutting the roller ball cartridge ( ), and a drive rod ( ) engaged with the control member ( ). Rotation of the drive rod ( ) moves the control member ( ) distally or proximally, thereby adjusting the bias force applied by the spring ( ) to the roller ball cartridge ( ).
