Abstract
A photographing apparatus detects whether a film winding assembly mounted utilizes an automatic or a manual film winding mechanism. The apparatus includes detecting means in the form of a diode across which a voltage is developed in response to a current flow through a film winding motor of the automatic film winding mechanism. The voltage developed across the diode permits a discrimination whether the film winding assembly mounted utilizes an automatic or a manual film winding mechanism.
