Cine-projector
摘要:
The present invention relates to a cine-projector so designed as to carry out the motion picture projection, the still picture projection, the quick film feeding as well as winding up by simultaneously controling the first clutch mechanism for selectively interrupting the engagement of the driving ower transmission mechanism with the feeding shaft rotated by means of the driving power of a motor rotating along a single direction through the driving power transmission mechanism by means of the translation mechanism to be translated at least into three positions in functional engagement with the operation mode change over mechanism for changing over the operation mode of the cine-projector, the second clutch mechanism for selectively interrupting the engagement of the driving power transmission mechanism with the winding up shaft rotated along the inversed direction as that of the above mentioned feeding shaft by means of the driving power of the above mentioned motor through the driving power transmission mechanism, the first control mechanism for controling the efficiency of the mechanism for intermittently feeding the film at the projection part and the second control mechanism for controling the binding mechanism for semi-compulsorily binding the film at the projecton part.
