<p>TARGET DEVICE The invention provides a target device comprising a board-like target member and a housing of low height that serves as a stand for supporting the target member in an upright position of use and encloses it when it is in a horizontal protected position with its front face down and its lower end near a rear wall of the housing. An elongated guiding device near the bottom of the housing, extending from near its front wall to near its rear wall, confines the lower end of the target board to back and forth motion. The front face of the target board at all times engages a sliding support on the front of the housing, spaced above the front end portion of the guiding device, so that back and forth movement of the lower end of the target board is attended by swinging of its upper end as it moves between its positions.</p> |
