Device for automatic access to virgin photographic media

摘要

The subject of the present invention is an automatic control in dark conditions or in inactinic light for access to an enclosed space via an opening controlled by a motor which opens and closes it. It is characterised in that the supply to the motor M is governed by a relay R1 turned on when a photoelectronic sensor C does not receive actinic light. It relates to a device for automatic access to enclosed areas for virgin photographic media. <IMAGE>
