Abstract: A media buffer capable of buffering two lengths of media, is fed a first length of media from an imagesetter at a first speed, and releases the media to a processor at a second speed. An input media sensor senses the media entering the buffer. Drive rollers take up the leading edge of the media at the imagesetter speed. Shortly thereafter a signal from an output media sensor located between the drive rollers and the processor, opens an input door to an input bin and stops the drive rollers. The incoming media continues to be fed by the imagesetter forming a first slack loop within the input bin. The imagesetter signals the buffer that the media has been cut, thereby actuating drive rollers to advance the media at the processor speed to a pair of rollers in the processor. A signal from the processor sensor opens an output door to an output bin. The drive rollers increase speed to transport the first piece of media from the input bin to the output bin thereby forming a second slack loop.

Abstract: A paper transporting device for a photographic printer. A pulse motor starts rotating during a magazine setting operation. The rotation of the pulse motor is transmitted to a pair of feed rollers through a pin-clutch mechanism and a paper feed gear train. Immediately before a paper magazine is completely attached to the photographic printer, the feed rollers nip the leading end of photographic paper and pull the photographic paper out of the paper magazine. When changing the paper magazine, a solenoid is turned on to change over the pin-clutch mechanism from the paper feed gear train to a paper rewind gear train. Thereafter, the pulse motor is rotated in reverse, so as to rotate a winding shaft of the paper magazine through the pin-clutch mechanism and the paper rewind gear train. An unexposed portion of the photographic paper remaining in the photographic printer is thus wound back into the paper magazine.

In addition, the band is sensed at a predetermined location of its path in order to ascertain the length of the band travelling by the predetermined location. The density and length data are sent to a microprocessor which uses the data to assign a position coordinate to each detected edge and its corresponding image. The position coordinates represent the positions of the images longitudinally of the band.

When the leading end of the photographic paper is returned back near the tip rollers, the epicyclic gear clutch mechanism is coupled to the nip rollers. In a second paper winding operation, the nip rollers are rotated reversely until the photographic paper detaches from the nip rollers.

Abstract: A method and apparatus for determining whether a predetermined cut position lies within an unexposed portion of a roll of film is provided. A first density sensor 20 senses film density of a roll of film (10) and produces film density data. The film density data is stored in a first data storage device (50).
