Photographic camera with auxiliary control attachment

摘要

A multifunction camera has a main assembly in which a CPU controls the usual operating parameters represented by e.g. light metering, range finding, objective control and film transport in response to hand-set instructions and/or stored programme data with parameter setting confirmation via the LCD display. An axially control attachment having its own CPU parameter-setting keys and LCD display has a housing matched to the camera contour to enable its connection to the camera base such that the combination provides an extended range of photographic functions. Data is transferred in both directions between the two units via an optical link comprising the light emitting elements and receivers.
