ABSTRACT:
A stationary display member is mounted on a display apparatus and provided with a plurality of slots which communicate between front and rear faces of the stationary display member and which are disposed in parallel to and equally spaced a given interval from each other. A movable display member is mounted on the rear face of the stationary display member and comprised of a plurality of segments successively disposed on one another in a partially overlapped relation. Each segment has a width more than twice the slot interval such that about a half portion thereof is covered by the adjacent segment. The uncovered remaining segment portions are slidably inserted into the respective ones of the slots. A linear motor drives the movable display member to project the uncovered segment portions from the slots to change display.
