A device, which is especially useful in color scanning equipment and the like, for supporting a photograhic transparency on a scanning cylinder, in which the cylinder surface is provided with a window and a layer of magnetic rubber surrounding the window, and a trimming mask made of magnetic material held in position by the rubber magnet layer, thereby enabling the support of the photographic transparency to be scanned between the trimming mask and the magnet layer so that the transparency covers the window.

Photographic transparency supporting device

A motor-driven shutter mechanism comprising two shutter members adapted to open and close an exposure aperture for the passage of the incoming light therethrough. These shutter members are operatively coupled to each other and to the drive shafts of two motors through a motion translator for translating a rotary motion into a linear movement. Electric drive circuits for operating the motors are also disclosed.

Motor-driven shutter mechanism

Conventionally, color films must be used with the light source or illumination for which it was designed, such as for natural daylight, fluorescent-light or tungsten-light or, if used with another light source, a suitable conversion filter must be placed over the camera lens. However, an improvement in the emulsion of the film provide an improved type of film with which good printed images are available through a mere correction during printing of the film. The present invention provides a method and a device for detecting and recording the type of illumination through detection of their spectral properties and detection of existence of a flickering noise due to an alternating voltage of the commercial power supply, and a system for an automatic film development.

Illumination detecting and recording method and device therefor

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.

Process for producing microfilm copies and apparatus therefor

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. The apparatus also includes blower means which blows air from the exposure compartment and into and through the development processing compartment, and to the exterior of the apparatus, whereby the exposure compartment is sealed against corrosive vapors produced in the development processing compartment.
