Abstract
A roller ball pen (2) that permits a user to adjust the bias force that biases a roller ball cartridge (4) out of the pen (2) to suit the user's particular writing style. The pen (2) has a body (8) having distal and proximal ends, a roller ball cartridge (4) disposed in the body (8), a cap (10) removably disposed on the proximal end of the body (8), a control member (14) slidingly disposed in the cap (10), a spring (18) attached to the distal side of the control member (14) and abutting the roller ball cartridge (4), and a drive rod (16) engaged with the control member (14). Rotation of the drive rod (16) moves the control member (14) distally or proximally, thereby adjusting the bias force applied by the spring (18) to the roller ball cartridge (14).
