Abstract: A multifunction writing instrument comprising a body extending along an axis and receiving at least two writing elements, each writing element comprising a writing tip and being movable between a protruded position in which the writing tip extends out of the body and a retracted position in which the writing tip is retracted within the body, and an actuating mechanism comprising a spinner configured to move one of the writing elements at a time, one after the other, from the retracted position to the protruded position, a ratchet receiving the spinner, and a single button configured to actuate the actuating mechanism.

Abstract: A writing instrument, in particular a pen, comprises a housing comprising a front barrel and a rear barrel, the front barrel having a front opening, two or more cartridges for storing colorants or inks, each cartridge having a writing tip, at least one actuator for selectively moving one of the cartridges within the housing so that the writing tip of a selected cartridge extends through the front opening of the front barrel, and a cartridge guide member which is designed to guide the movement of the cartridges within the housing. The front barrel and the cartridge guide member are designed to be removed from the rear barrel for replacing one or more of the cartridges. In particular, the front barrel and the cartridge guide member may be removed from the rear barrel while the cartridge guide member may remain mounted to the front member at the same time.

Abstract: Writing instrument having a body, a clip, and a retractable eraser device movable between a first position and a second position, the clip forming a housing that is designed to receive all or part of a gripping portion of the eraser device in the first position.

Abstract: A multi-function writing instrument comprises a body extending in an axial direction, at least two writing elements arranged inside the body, each writing element comprising a writing head able to take up a retracted position in which the writing head is stowed in the body and a writing position in which the writing head protrudes from the body, one of the writing elements being a lead-holder system comprising a lead-holder mechanism and a lead container, the lead container comprising a side opening for inserting leads.

Abstract: Multifunction writing instrument comprising a body extending in an axial direction and housing at least two retractable writing elements and a ring portion movable in rotation. The ring portion having at least as many pairs of guide surfaces as retractable writing elements. The writing elements include buttons. Each button is configured to cooperate with a respective one of the pair of guide surfaces of the ring portion. Actuation of the button of a writing element facilitates movement of the writing element from the retracted position to the writing position and returns any of the other writing elements in the writing position to the retracted position, whereby at most, one writing element is in the writing position.

Abstract: A multifunction writing instrument comprising a body extending along an axial direction and housing at least two writing elements, each writing element comprising a writing tip, a selector device configured to select one writing element from among the at least two writing elements, a retraction device configured to move a selected writing element between a writing position in which the writing tip of the selected writing element projects from the body and a retracted position in which the writing tip of the selected writing element is retracted, and a return device configured to bring a writing element from the writing position to the retracted position when the selector device is activated while a writing element is in the writing position.
