Abstract
A motor-driven film winder for use with a camera includes an exposure inhibit signal generator for generating an exposure inhibit signal when the number of frames to be exposed which is set by an exposure setting unit coincides with the number of exposed frames counted by a counter. The motor-driven film winder also has an unexposed frame indicator for indicating the difference between the number of frames set by the exposure setting unit and the count of the counter as the number of remaining unexposed frames when a shutter release operation of the camera is interrupted before the count of the counter reaches the preset number of frames to be exposed, and an intermittent exposure canceling signal generator for issuing an intermittent exposure cancelling signal to an intermittent exposure signal generator when the preset number of frames to be exposed coincides with the counter of the counter.
