Abstract: A writing implement has a writing tip extending from the barrel for writing and a rubbing element that surrounds the writing tip that is selectively extendable from a housing to erase or change color of the writing and retractable into the housing for storage.

Abstract: A writing instrument comprising a body extending along an axial direction and an erasing device comprising an eraser, the erasing device being disposed at an axial end of the body of the writing instrument, the eraser being able to assume a use position and a protection position, the eraser being configured to switch from the use position to the protection position by a displacement of the eraser by means of an actuation device of the erasing device, the actuation device being configured to be actuated along a axis perpendicular to the axial direction.

Abstract: 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.

Abstract: The pocket video player comprises a screen 1 and a keypad 2. The keypad 2 is composed of rocking keys each controlling two antinomic functions which cannot be activated simultaneously. Three of the adjacent keys (4c, 4d, 4e) constitute a navigator with rocking keys. The central key (4d) controls two opposite directions and the two side keys (4c, 4e) each control one of the two other directions respectively. Useful for increasing the size of the screen, reducing the size of the keypad, and making the actuation of the functions easier and more reliable.
