Abstract

PURPOSE:To realize a mass production of a large-size projection type TV, by forming two projectors independently of each other to facilitate easy handling and to ensure a free assembly for both the lateral and longitudinal constitutions in terms of the design. CONSTITUTION:A projector consists of a projector cabinet transmission type screen 2, reflective mirror 3, speaker net part 8 for speaker 7, a back cover 4 of cabinet, etc. At the same time, another projector is formed with a control panel 11 attached to a projector cabinet, covers 12 and 13 of the lateral and longitudinal aperture parts respectively, a projection chassis 18 incorporating a projecting CRT, a lens, etc., a reflective mirror 14 which is used in case the projector is used as a lateral type, a reflective mirror storing mobile groove 15 which is used in case the projector is used as a longitudinal type, etc. Then a free assembly is secured for both the lateral and longitudinal types of the projector in terms of design. Thus the constitution is simplified for a large-size projection type TV to realize a mass production.
