Title: Camera with automatic film advance

Abstract: A camera which is capable of being operated, at the option of the operator, either continuously to make a series of exposures in an automatic manner or in a single-exposure manner according to which the operator may make a single-exposure. In the continuous operating mode, the camera is capable of making exposures either with a preselected time interval from one exposure to the next or in a manner according to which the exposures are made as rapidly as possible taking into consideration the exposure time required for each exposure. Also, the camera is capable of being operated to make bulb exposures. Irrespective of the type of operation selected for the camera, the camera cannot stop operating until the film has been advanced in preparation for making the next exposure and the shutter is in a cocked condition, so that in this way no time is lost as, for example, when the operator decides to make a single exposure after the camera has been operated in a continuous mode.
