Abstract

PURPOSE: To prevent the blur of photographing screen and to reduce the power consumption by switching the damping method in accordance with the continuous photographic mode and the single photographic mode.
CONSTITUTION: In case of a continuous photographing, a switch SW 2 is kept turned on, and the short-circuit of a motor M is not released even after the completion of film winding, and therefore, the short-circuit of the motor M2 is not released during film exposure to prevent the blur of the screen, due to slight movement of the film. When it is detected that the extent of movement of the film is slightly smaller than a value corresponding to one photographed frame, the driving current of the winding motor M2 is interrupted to reduce the speed of the motor M2; and when the extent of movement of the film corresponds to one photographed frame, both ends of the motor M2 are short- circuited to damp the motor M2. The short-circuit of the motor M2 is not released in case of the continuous photographic mode, and the short-circuit of the motor M2 is released a prescribed time after in case of the single photographic mode. Thus, the blur of photographing screen is prevented and the power consumption for damping is reduced.
