摘要 PURPOSE:To store information on a film loading date by outputting a film loading date signal to a memory means when the tip of a film is detected to be wound by a spool. CONSTITUTION:When a switch S4 is pressed, a film loading date display deciding circuit 47 outputs display switching signals CHA to transmission gates 16-18, whose outputs are switched to a piece of information on date, month and year information memory circuits 19-21 from a piece of information of data, month and year counters 13-15, and transmitted to multiplexers 22-24. At this time a display mode selecting circuit 25 has inputted display mode signals M1-M7, and the multiplexers 22-24 select information corresponding to the signal. The selected information is led to decoders 26-28, and displayed on displays 32-34 through driver circuits 29-31, whereby the film loading date corresponding to the selected display mode is displayed. Thus the information on the film loading date is properly stored.
