Abstract

PURPOSE:To avoid a cut-off of a screen and an uncoincidence between the right and left focuses, by securing a switching structure for the supporting members that support the two projecting tubes located at both ends of the three different color tubes provided horizontally. CONSTITUTION:The hoods 5G, 5R and 5B are attached in front of the projecting tubes 3G, 3R and 3B of three different colors, respectively; and the magnifying lenses 2G, 2R and 2B are provided inside those three hoods in a movable way toward the optical axis. Thus the projecting tubes are unified to the magnifying lenses for each color. Then the tubes 3R and 3B are supported fixedly by the supporting members 6R and 6B, and these members 6R and 6B are constituted to have a free swing in the horizontal direction. Thus a free control is secured for the angles of the optical axes 4R and 4B of the tubes 3R and 3B at the both sides to the optical axis 4G of the center tube 3G in accordance with the sizes of the screens 1 and 11.
