ABSTRACT:
An electro-optical display panel is disposed within a finder in order to provide an alarm display and/or a display of camera operation state. If lens barriers are closed or a proper exposure control or focal adjustment is not possible, the electro-optical display panel is made in a light intercepting state, and the optical path of the finder is closed. According to a preferred embodiment, the electro-optical display panel is constructed of a plurality of display segments. The display segments are selectively driven to change their light transmitting state and display the shutter operation and/or film transportation state.
