  • Patent number: 4192594
    Abstract: A camera portion and a processor portion are combined so that the film exposed in the camera portion is processed in the processor portion. The camera portion is provided with a roll film take-up magazine and a cutter for cutting a roll film into sheet film. When roll processing is desired, the exposed roll film is taken up in the roll film take-up magazine and the magazine is put into the processing portion. When sheet processing is desired, the exposed roll film is cut into sheet film in the camera portion and fed into the processor portion. The processor portion is provided with a first film passage for guiding the sheet film into the processor and a second film passage for guiding the roll film into the processor. The processor portion has a roll film magazine holding device for holding the roll film take-up magazine so that the roll film taken out thereof is guided into the processor through the second film passage.

  • Patent number: 4119952
    Abstract: An apparatus for monitoring photographic processing liquid composed of a timer to determine the length of time which has passed after the renewal of the processing liquid, a counter to determine the amount of the photographic film which has been already processed and an alarm light which is responsive to either timer or counter when having reached the respective predetermined position for lighting to indicate that the photographic processing liquid must be renewed. Thanks to the monitoring in terms of the "effective length of time" of the processing liquid and of the total amount of the photographic film already processed, it is assured that the processing liquid is renewed before it has been exhausted and has lost the processing capability.

  • Patent number: 4076412
    Abstract: Process for producing microfilm copies and apparatus therefor employing silver halide emulsion film which is provided in roll form, wherein subsequent to exposure of the frames of the image-carrier portion the film is advanced a set length without being exposed this unexposed portion constituting the tab portion of the succeeding microfilm unit, and then the exposed image-carrier portion of the film, also preceded by a tab portion, is detached by cutter means from the remainder of the film and processed independently in the same apparatus, and moved to the exterior of the apparatus. An identification code may be written manually on the tab portion of each microfilm unit or may be produced automatically thereon by supplementary film exposure means upon exposure of the first frame of the image-carrier portion of each microfilm unit.

  • Patent number: 4066354
    Abstract: Microfilm apparatus suited to use in a small establishment and employing standard microfilm in roll form. Successive microfilm units each comprising an image-carrier portion constituted by a set number of frames which have been exposed in an exposure compartment in the upper portion of the apparatus to image-wise light reflected from documents to be microfilmed and a tab portion for carrying an identification code indicative of the content of documents recorded on the image-carrier portion are detached from the remainder of the film and immediately processed in a development processing compartment in the lower portion of the apparatus, remaining film being available for production of subsequent microfilm units, and processed microfilm units being moved to the exterior of the apparatus.

  • Patent number: 4064677
    Abstract: A microfilm inserter having a table for retaining a microfilm jacket in a fixed position is provided with a pair of feed rolls at either end of the table, a detecting means for detecting the trailing end of a microfilm strip to be inserted into said jacket, and a cutter for cutting off the leader of said microfilm strip. A film strip having a leader is fed through the feed rolls at one end and into the insertion slot of the jacket. When the leader exits from the far end of the jacket, it passes between the other pair of rolls and the film strip continues to be transported even after the trailing end thereof has passed through the feed rolls at said one end. When it is detected that the trailing end of the film strip has arrived at a predetermined position, the film strip is stopped and the leader is cut off along the far end of the jacket.
