Abstract

PURPOSE:To open and close a mirror box with a weak force and to achieve fine adjustment of an open angle, by locating the mirror box freely capable for opening and closing by taking a shaft as a fulcrum and containing a control rod from a long hole provided at a side wall of a main body to a hollow part at the inside. CONSTITUTION:A screen 2 is fitted to a main body 1 where a projective tube is contained, and a mirror box 4 having a mirror is installed freely capable for opening and closing by taking a shaft 5 as a fulcrum. A control rod 8 is contained from a long hole 23 provided at the side wall of a main body 1 into an internal hollow section 24, and another end of the control rod 8 is put in a recess 24 of the box 4. When the box 4 is folded, since a spring 11 is energized, the box 4 can be opened with a weak force. As the box 4 is opened, since a spring stand 12 shifts left and a spring 13 is shrinked, the box 4 can be opened smoothly without being rapidly opened by the weight of itself. Simiarly, the box can be closed with a weak force and the open angle of the box can be maintained to a suitable state by the adjustment of a bolt 17.
