Abstract

PURPOSE: To photograph accurately and clearly even very rapid development, by controlling the number of rotations of a variable speed motor which rotates the rotary disc having a slit and by providing a device which detects and displays the number of rotations of the rotary disc in the umbrella.
CONSTITUTION: Optical lens 1, camera main body 2, and umbrella 3 between them are provided, and the rotary disc having slit 5 is stored in concave 4 of camera 3. Disc 6 is rotated by variable speed motor 7, and the number of rotations is controlled by controller 8. The number of rotations of the disc is detected by detector 9 and is displayed on display equipment 10. Detected object 11 is fixed in the position symmetrical to slit 5 of disc 6 and is detected by position detector 12. The output signal of detector 12 and the signal of the X contact of camera main body 2 are input to measuring equipment 13. Detected object 11 reaches the position nearest to detector 12 when slit 5 gets across the optical axis, and therefore, a signal is output from detector 12.
