发明名称 Recording device and projecting device for motion picture film
摘要 A device for recording a motion picture film and a device for projecting a motion picture film susceptible to generation of low noise due to film feed are provided. A motion picture film 10 is fed on the frame basis so that the film is fed as it is clamped between an idler 45 and a rotary drum 48 and so that the film feed is stopped as a voice coil 43 is driven for displacing the idler 45 away from the rotary drum 48. A recording unit 30 records a frame image of the motion picture film each time the film feed is halted. Recording may be made in this manner under the state of extremely low noise level due to film feed. Film feed is made in a similar manner during projection of each frame image, and each frame image is also projected by a projection unit 70 each time the film feed is halted. Projection may also be made in this manner under the state of extremely low noise level due to film feed.
