A hand held device presenting a first head and a second head that are movable axially between a position for use and a retracted position, and a single side button configured to bring the first head and the second head, independently of each other, from the retracted position to the position for use and vice versa, the side button cooperating with a first ratchet mechanism in order to cause the first head to pass from the retracted position to the position for use and vice versa, and with a second ratchet mechanism in order to cause the second head to pass from the retracted position to the position for use and vice versa.

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.

A hand-held device, in particular a writing instrument, comprising a body, a single carriage carrying a first head and a second head, or a first carriage and a second carriage carrying respectively the first head and the second head, and a blocking device including a cavity and a ball, the ball) blocking the single carriage or the first carriage when the first end is below the second end, such that the first head is blocked and projecting while the second head is retracted, and the ball blocking the single carriage or the second carriage when the first end is above the second end, such that the second head is blocked and projecting while the second first head is retracted.

A feeding pencil includes a body, a leading tube, a middle tube, a pipe member including drawing materials, a movable body, a holding member, and a sliding part. The drawing material moves forward in the leading tube when the pipe member engages with the leading tube in a rotating direction by moving the sliding part forward by a predetermined amount, when the leading tube and the body are rotated relatively in one direction while the pipe member is engaged with the leading tube in the rotating direction. The sliding part includes a stick-like part with a spring, and the stick-like part is inserted into an opening of a housing, and the sliding part is urged rearward by the spring when one end of the spring abuts the housing, and the other end of the spring abuts a face protruding radially outwardly from the stick-like part.

A feeding pencil includes a pipe member, a leading tube, a tubular main body, a movable body, and a holding member. The pipe member is disposed inside the leading tube and loads a drawing material. The movable body extends in an axial direction includes a male screw formed across an entire outer periphery thereof in the axial direction. The holding member holds the movable body. The pipe member includes a female screw on an inner surface thereof. The female screw screws with the male screw. A relative rotation between the leading tube and the main body relatively rotates the pipe member and the holding member and acts a screwing action between the male screw and the female screw. The screwing action moves the movable body forward to extrude the drawing material from the pipe member.
