Abstract
A character shielding-preventive pointer instrument for automotive gauges includes a polarizer film having permeability or non-permeability characteristics selectively depending on whether power is supplied thereto. The polarizer film is attached on a lower surface of a front end portion of a pointer needle positioned just above characters of a character plate. Whether or not power is supplied to the polarizer film is controlled depending on the current position of the pointer needle by a micro computer such that the polarizer film is permeable to light when the pointer needle is located above a character of the character plate so that light emitted from the character plate passes through the pointer needle through the polarizer film to prevent the pointer needle from shielding the character.
