Abstract
PURPOSE: To make possible the imprinting of always fresh data by digitally displaying film sensitivity on the back cover and changing over LED light emission time.
CONSTITUTION: A liquid crystal display body 7 and switch block 8 are provided on the front of a back cover 4 and a circuit block for letting LED 5 emit light by the shutter trigger signal is mounted in its inside. When a sensitivity select switch 11 is operated, a sensitivity state is maintained by an n-system counter 12 and the contents thereof are decoded 13 to become time width selection signal 14 which is then inputted to a gate for setting the LED lighting time width of a time setting circuit 15. Also, the signal 14 is sent to a display change-over circuit 16, by which the sensitivity state is selectively displayed 18. On the other hand, when the camera trigger signal 19 is inputted to the circuit 15, an LED 21 is lighted for the time having been set by the signal 14, whereby the data are imprinted on film.
