ABSTRACT:
The invention consists of an apparatus for recording accidental events relating to movable devices such as automotive vehicles, which events can be sensed by optical observation, and comprises: detecting means for receiving the images of the event and transforming them into electric signals; a signal storing circuit comprising one or more analog memories, wherein the recording of successive events is carried out by automatically erasing the oldest image; and sensor means for assuring automatic interruption of the incoming signal flow from the image detecting means to the memories to achieve the automatic nonerasable storage of images corresponding to a predetermined period immediately preceding and contemporary to the accidental event.
