Abstract: A rotary camera for photographing a plurality of original documents on microfilm and for recording information relating to the photographed original documents together with data concerning the conditions for photographing additional necessary data. The rotary camera has an exposure roller on which images of the original documents are focused to be photographed and unidimensionally arranged light emitting elements opposed to the exposure roller. The light emitting elements are selectively energized so that the microfilm is exposed to the data-writing lights forming any desired images of the data in the form of letters, numerals or marks while moving in contact with the exposure roller. The data to be recorded is designated and is put into the control system through a keyboard. A jam-mark may be recorded on the microfilm as the data in response to an output from a jamming detector.

Abstract: A rotary camera for photographing an original image on a document sheet so that a photographed image is formed on a frame of a microfilm roll. The document sheet is fed from a document feed port onto a rotary drum which comprises a hollow cylinder having an outer periphery provided with multiple small through-holes and suction means for sucking air through the multiple through-holes so that at least a zone of the document sheet exposed to photographing light is closely fitted over the outer periphery of the hollow cylinder. The photographed document sheet is stripped from the hollow cylinder by document stripping means disposed downstream of the suction means and then discharged through a document discharge port. Preferably, a buffer zone is provided between the suction means and the document stripping means to facilitate smooth stripping and preventing folding of the document sheet.

Abstract: A microfilm retrieval includes first and second motors for respectively conveying at a high speed a winding section and rewinding section. The winding section and rewinding section are provided with a pair of nip rollers therebetween so as to hold the microfilm. A rotary shaft is axially mounted to the nip rollers and is connected to a low speed motor via an electromagnetic clutch in order to convey the microfilm in both directions at a low speed. First through fourth controllers are respectively provided for controlling the first and second motors, the electromagnetic clutch, and low speed motor. Additionally, a fifth controller is provided for driving the first and second controllers, and a detector is provided for detecting image frames on the microfilm.

Abstract: A film storage device, such as may be used for temporarily storing microfilm between a photographing section and a processing section in a unitary photographing/processing apparatus, in which the cut end of the film is prevented from being wound up onto take-up reel after cutting. First and second reels are rotatably mounted along an axis which is perpendicular to a rotatable shaft bearing the two reels. A rotary plate is connected to the shaft having a plane which is also perpendicular to the axis of the shaft. A drive belt is selectively engageable with the take-up reel or the rotary plate. The position of the drive belt is synchronized with a cutting mechanism. A stretchable elastic drive belt is laid between the take-up reel and a film guide roller. When the film is cut, elastic force accumulated in the drive belt is released, causing the take-up reel to rotate reversely, and thereby preventing the cut end of the film from being wound onto the take-up reel.
