ABSTRACT:
Apparatus for fixing a flash unit to a camera is disclosed. The apparatus includes mounting magnets and a structure for shielding the fields produced by the mounting magnets in a first undocked position and for exposing the fields produced by the mounting magnets in a second docked position. The apparatus further includes a mounting structure effective in the first undocked position for causing the flash unit to be moveably mounted to the camera and for leaving the shielding structure in the first undocked position and effective when the flash unit is moved to the second docked position for causing the shielding structure to be in the second docked position whereby the exposed fields produced by the mounting magnets cause the flash unit to be fixed to the camera.
