Abstract

In microfilming a plurality of documents, it is necessary to lay out the documents in a format so that they can be photographed on a frame of microfilm in the proper sequence. If the data is carried on both sides of the documents, it also is necessary to photograph one side of the document, turn the documents over, and photograph the other side.

Document Composing Device

In microfilming a plurality of documents, it is necessary to lay out the documents in a format so that they can be photographed on a frame of microfilm in the proper sequence. If the data is carried on both sides of the documents, it also is necessary to photograph one side of the document, turn the documents over, and photograph the other side.

Because this formatting is time-consuming, it is desirable not only to do the formatting separate from the microfilming or off-line but it is also to be able to quickly flip the documents from one side to the other without having to reposition them. This is accomplished by employing this composing device. The device comprises baseboard 1 covered with black felt or other light absorbing material. Optically clear transparent carriers 2 are fastened to board 1 such that they can be flipped from one side to the other. In operation, the documents are inserted in carriers 2 of the device off-line from the camera.

After documents 3 are loaded in carriers 2, the composing device is positioned beneath the camera and a frame of microfilm is exposed to one side of the documents. Only this portion of the microfilm frame is exposed because no light is reflected back to the other portions due to the light absorbing black felt. Next, carriers 2 are flipped over and the same frame of microfilm is exposed to the other side of the documents. Thus double exposure of the film results in both sides of the documents b...
