PURPOSE:To mount and fixing slide original pictures accurately, by changing freely simultaneously horizontal angles of respective reflective mirrors and mount tables of plural projecting units provided in parallel and making it possible to adjust angles of elevation of reflective mirrors. CONSTITUTION:Light sources 2 and 2' and condenser lenses 3 and 3' are installed in a light source casing 1 so as to face each other vertically and are arranged on the same axial lines as projection lenses 5 and 5', which are provided on the casing 1 through an attaching arm 4, to constitute parallel slide projecting units 6 and 6'. Turning cylinders 8 and 8' are fitted freely turnably to attaching cylinders 7 and 7' of projection lenses 5 and 5', and reflective mirrors 13 and 13' are attached on cylinders 8 and 8' so that angles of elevation are changed freely. Since mount tables 15 and 15', where slide original pictures should be mounted, and reflective mirrors 13 and 13' are turned as one body in the horizontal direction by turning of an operating shaft 16, pictures on a screen are moved horizontally, and further, they are moved vertically by adjusting angles of elevation of reflective mirrors. |
