PHOTOGRAPHIC APPARATUS WITH ELECTRONIC EXPOSURE CONTROL

摘要

The top portion of the housing in a still camera has an opening for insertion and withdrawal of a drawer-shaped insert which contains one or more removable batteries and is received in a socket of an insulating plate which is mounted in the housing and supports one or more potentiometers, transistors or other components of the electronic exposure control. Such components are accessible by way of the opening upon removal of the insert. A wheel on the insulating plate can be rotated by hand and serves to adjust the exposure control in accordance with the guide number of a flash unit and/or in accordance with the speed of film. The wheel also serves to partially expel the insert from the socket. Leaf springs are employed to clamp the insert in the socket and to connect the poles of the battery into the circuit of the exposure control.
