Abstract
A film applying and removing device in a drum type picture scanning recording apparatus is adapted that a photosensitive film is wound onto a rotary drum to be scanned by an exposing head, and comprises a first tray for accommodating a plurality of unexposed films, a film ascending and descending means for ascending the tip end of the film in the tray to contact it with the surface of the drum, a vacuum suctioning means to hold the tip end on the surface of the drum, an inversely rotatable driving means to rotate the drum and guide means for introducing a second tray for receiving exposed films.
Claims9
A film applying and removing device in a drum type picture scanning recording apparatus in which a photosensitive film is wound onto a rotational drum to be scanned and exposed by an exposing head, characterized by the following:
- a frame,
- a first tray on said frame for supporting a plurality of unexposed photosensitive films in overlapped manner, with each film having a tip end,
- a scanning drum on said frame positioned substantially over the tip ends of said films in spaced relation thereto,
- conveying means on said frame for raising and lowering the tip ends of said films with respect to said drum, and being adapted to raise selectively the tip ends of said film into contact with said drum,
- a vacuum suctioning means attached to the body of said drum to hold only the tip end of one of said films in contact with the surface of said drum,
- a drive means secured to said drum for selectively rotating said drum in opposite directions, and
- a second tray on said frame for receiving exposed films for said drum, and
- guide means on said frame for guiding said exposed films into said second tray.
