<p>PURPOSE:To provide the system effective for photographing by photographing the data display devices of speed violating cars and running speeds on the same film and storing the speed signals with a data recorder which is actuated by warning signals. CONSTITUTION:The speeds of a running car 1 are counted in a counting circuit 6 by the Doppler signals of a transmission-reception circuit 4, and are displayed in a data display device 13. These are then compared to the warning speed from a warning speed setting switch 8 with a comparator 10 and when the warning speed is exceeded, the shutter 14 of the camera is actuated to photograph the running car 1 and data display device 13 on the same film, at which time the a data recorder 15 is operated by the warning signal 11 so as to perform the storage of the speed signal. Hence, the data conerning the speeds are subsequently stored in the recorder 15 simultaneously with photographing and therefore these ae processed with an electronic computer, etc., whereby the system effective for photographing may be provided.</p> |
