A microfiche camera suitable for use in a low cost microfiche system for exposing a plurality of image frame areas on a single card-like film unit, preferably of the self-developing type. The camera includes a lens mounted on a carriage for lateral movement relative to the film unit, a film advancing system for moving the film in increments longitudinally relative to the lens and an exposure system, operable in cooperation to record an orthogonal pattern of micro images on the film unit. A camera actuating system is operable to locate an image frame area in position for exposure in response to movement of an actuating button from a first position to a second position and then to effect exposure of that image frame area in response to return movement of the button to the first position. The film advancing system is also used to advance the film unit into engagement with film processing structure after exposure of the last image frame area. However, provisions are made for overriding the normal operation of the film advance system to allow the manual advance of the film unit for processing prior to exposure of the last image frame area. The camera also includes a reset system for returning the lens carriage to a predetermined starting position in response to advancing the film unit into engagement with the processing structure.
