Abstract

PURPOSE: To perform photographing of various modes with simple mechanism operation by controlling a counter which performs changing over of various photographic modes by means of a mode setting member and a pulse generating means.
CONSTITUTION: A program card inputting part 12 and a pulse generating circuit 40 are connected to a photographic mode changeover counter 14. Then, if one of the cards for setting various photographic modes is selected and inserted into the program card inputting part 12, the potentials having been set are inputted from terminals m1 thru m3 to terminals A thru C and the photographic mode having been selected is set and is displayed in the display circuit 43. At the same time, the pulse inputting to terminal T is inhibited and further the photographing in the mode having been set via the decoder 44 is automatically accomplished. When there are no setting cards, the switches S5, S1 of a switch group 18 are turned ON, then a pulse generating circuit 40 is operated and the pulses are inputted to the terminal T, by which the counter 14 is operated to subsequently set the various photographic modes which are then displayed in the display circuit 43, thus the selection of arbitrary photographic modes becomes feasilbe.
