Abstract

PURPOSE: To finely adjust the interval of a video display part by providing a mechanism which freely connects and disconnects two hollow feed screws and an adjusting knob and moving two video display modules integrally or individually. CONSTITUTION: Hollow shafts 2L and 2R which have a counterclockwise male screw and a clockwise male screw are supported rotatably by one guide shaft 3. Further, a friction driving part consisting of two sleeves 5 which are pressed against the end surfaces of the hollow shafts 2L and 2R to rotate together with the guide shafts, a compression coil spring which is arranged between the sleeves 5, and the adjusting screw 4 which is fitted onto the outer peripheral part so as to rotate the sleeves 5 is provided between the hollow shafts 2L and 2R. When the adjusting knob 4 is rotated, its turning force is transmitted to the respective right and left sleeves 5, whose turning forces are transmitted to the hollow shafts 2L and 2R. The video display modules 1, therefore, move by the same distance in the mutually opposite directions through the rotations of the counterclockwise and clockwise male screws cut in the outer peripheral parts of the hollow shafts 2L and 2R.
