Patent

CA 2540651

The invention relates to a writing instrument, comprising a body (2), a lateral button (7) with a first cam (11) and a forwarding mechanism, having a movable member (20) with a first inclined plane (23). The lateral button (7) remains in a release position, in which the first cam faces the first inclined plane and can perform a first tilting movement, during which the first cam cooperates with the first inclined plane. Said button (7) comprises a second cam (12) which is longitudinally displaced from the first cam and the movable member has a bearing (25) which is adjacent to the second inclined plane (26). The second cam (12) is supported on the bearing during the first tilting movement and faces the second ramp at the end of said movement. The button can then perform a second tilting movement, during which the second cam cooperates with the second inclined plane.
