ABSTRACT:
A device for use in conjunction with a copying machine to allow the owner of the copy machine to ascertain instantly each copy made on a particular machine, the date the copy was made and time of the day. The device includes a camera mounted optically in communication with the copy holder, a camera lens adjustment to accommodate standard and legal size microfilm photographs, a display for date, time, and frame member optically positioned in the camera field, and a switching circuitry for driving the camera one frame at a time relative to the print actuation of the copy machine. The camera is connected to be activated only when the initial print button is selected on the copy machine. Once a photograph has been taken, the camera will move to the next frame and await the next pressing of the copy machine print button. The device may be used to simultaneously make copies of a particular file while at the same time providing a storage copy on microfilm. More importantly, the device allows the copy machine owner to preserve a dated and chronologically numbered microfilm record of each copy made on the machine. The camera unit is hidden within the copy machine and may be locked to require a key for removal of the camera. An instant print film in a cassette may be utilized so that at any given moment the film would be available for determining a particular copy.
