Claims (1)

[Scope of Claim for Utility Model Registration] An automatic exposure time timing circuit 3 that controls the shutter at a shutter time according to the brightness of the subject so as to obtain proper exposure; a film frame number counter 2 capable of generating a counting output when a second predetermined number of frames greater than the first predetermined number of frames is reached;
4, 7, 8, instead of the shutter time to obtain the appropriate exposure,
A timing forcing circuit (not shown) that forces the controlled shutter time to a constant second; and a timing forcing circuit (not shown) that performs photography at a shutter time of a constant second by the timing forcing circuit until the first predetermined number of frames is counted. After counting the first predetermined number of frames, there is a first state in which photography is performed at the shutter time by the automatic timing circuit, and a constant second state by the timing forcing circuit until the second predetermined number of frames is counted. After the second predetermined number of frames has been counted by taking pictures at the shutter time of An aerial photography device for a camera, comprising an aerial photography frame number changing means 5 which switches from a first state to a second state in conjunction with each other.
