Abstract: A computer controlled microfilm camera system and method for microfilming data onto pre-cut individual microfiche film sheets in one of a plurality of formats selected by a system user. The camera system includes a reusable cartridge which permits the single microfiche film sheet to be substantially withdrawn and exposed, and then reinserted into the cartridge for processing in a daylight loading processor. The cartridge is supported on a movable carriage assembly which is connected to a first drive system and stepping motor so as to provide for translation of the film sheet in a column direction. The carriage assembly supports a second drive system and stepping motor which is connected so as to provide for translation of the film sheet in a row direction. A pre-programmed microprocessor controls the incremental stepping of the film sheet in directions determined in response to format selection data input to the microprocessor by a system user, identifying one of a plurality of format tables stored in the microprocessor. The microprocessor additionally controls the order of movement of the film sheet in order to expose the film in either a row mode or a column mode as specified by the user.

Abstract: A step-and-repeat camera wherein the multiple exposure frame format can be varied and preset by the operator. Thus, the number of exposure frames per column and the number of columns per fiche can be varied as desired so as to accommodate the sizes of different sets of materials to be photographed, for example. Means are provided for blanking out specific areas in fiche to accommodate title placement or other identification, spacing between successive sets of materials, and so forth. Visual means are provided for identifying a particular frame about to be exposed, and also for separately identifying successive exposures on the fiche film itself. Other improvements herein include an improved vacuum platen that accurately positions the film for proper exposure at a desirably reduced plan area. Film spool and film take-up cartridges with associated equipment are supplied in improved structural design. The camera carriage itself, by a pair of stepping motors, is advanced so that successive frames in each column and successive columns can be accommodated. Various exposure formats are likewise made possible through the design of the equipment.

Abstract translation: 一种步进重复照相机，其中多个曝光帧格式可以由操作者改变和预设。 因此，例如，每列的曝光帧数和每个图像的列数可以根据需要而变化，以适应不同组的要拍摄的材料的尺寸。 提供的手段用于消除文件中的特定区域以适应标题放置或其他识别，连续的材料组之间的间隔等。 提供视觉手段用于识别要暴露的特定框架，并且还用于单独识别胶片本身上的连续曝光。 这里的其它改进包括改进的真空压板，其精确地定位胶片以在期望的减少的平面区域适当曝光。 具有相关设备的薄膜卷轴和薄膜卷取盒具有改进的结构设计。 相机托架本身通过一对步进马达前进，使得可以容纳每列和连续列中的连续的框架。 通过设计设计，也可以实现各种曝光格式。
