ABSTRACT:
A microfilm camera for photographing a plurality of originals on a microfilm is disclosed. The improved microfilm camera is provided with a display lamp for indicating that an original is left in a non-photographed state and a buzzer for issuing an alarm on that occasion. If the original non-photographed is left as it is, the display lamp turns on and the buzzer sounds. Accordingly, the original to be photographed is not left in the non-photographed state for a long period.
