PURPOSE:To make the form of a mirror fixture compact and to reduce transport cost and package cost by packaging, transporting the device while vertically raising a mirror when the device is sent out, and fixing the mirror while being inclined after the device is picked up. CONSTITUTION:A picture is outputted from a cathode ray tube 2 and reflected on a mirror 1 by a projector lens 3 and the picture is back projected on a screen 4. In such the case, rotary shafts 5a are provided at the mirror 1 and at a central part between the both ends of a fixing member 5 for the mirror 1, and at the fixing part 5, a cover 8 is provided with a flange for sealing the inside of a housing 7 when vertically raising and inclining the mirror 1, and turn shafts 8a parallel to the rotary shafts 5a. At the time of transportation, by vertically raising the mirror 1 and fixing the turn of the mirror 1 to the housing 7 by the cover 8 and screws 9, the external dimension of the device in the packed state can be reduced. Thus, the transport cost and the package cost can be reduced. |
