The apparatus for three dimension movie comprises a semicircle rotary plate (18) and moving rods (2)(2') which feed films (1)(1') projected by two lens (27)(27') alternatively. The rods the end of which can be inserted into a feeding groove (10) of films are fixed to a bracket (6) by shafts (3)(3'). The semicircle rotary plate driven by a rotary plate (18') and a motor (17) is rotated in a phase detecting sensor (19) which includes a phase detecting part (20) and a polar detecting part (21) to transmit signal, and an optical part (22) to receive the signal. The optical part includes an elastic rod (24) provided at a shafts (24) so that cover plates (25)(25') of the shafts vibrats up and down by an electro-magnet.
