Abstract
Abstract A mode selecting device for use in a camera having at least two modes, namely, a consecutive picture taking mode and a single picture taking mode. In the consecutive picture taking mode, the camera operates to take pictures consecutively so long as the exposure release button is depressed. In the single picture taking mode, the camera operates to take a single picture no matter how long the release button is continuously depressed. The selected mode is displayed on a display. The camera returns to the single picture taking mode when the back lid is opened, when the back lid is closed, when the film is rewound, or when the film undergoes preliminary winding so that the camera is not inadvertently left in the consecutive picture taking mode.
