Abstract

PURPOSE: To make possible photographing in various kinds of modes without entailing complexing and larger size of mechanism by making various kinds of photograhic modes changeable according to the count balues of a counter.
CONSTITUTION: A display circuit 43 and further a decoder 44 are connected via mode changeover counter 14 and decoder driver 42 to a program card inputting part 12 and a switch group 18 is connected via NOR gate 20 and NAND gate 13 to the mode changeover counter 14. Then, if one of the cards for setting various photographic modes is selected and is inserted into the program card inputting part 12, the potentials of terminals ml thru m3 become set ones which are then preset at the input terminals A thru C of the counter 14 and the mode selected by the output of the counter 14 is displayed in the display circuit 43. At the same time, photographing is automatically accomplished in the selected mode by way of the decoder 44. When there are no cards for setting the photographic modes, the switches S5, S1 are turned ON, then the counter 14 is operated by the pulses from a pulse generating circuit 40, whereby the various photographic modes are subsequently changed over and becomes selectable.
