ABSTRACT:
A door actuated message device includes a quick attach-detach mounting bracket for installation of a self-contained message unit adjacent a door of a business establishment or the like for actuation of an adjustable lever arm connected to a microswitch unit. The microswitch unit is mounted on a rotatable disc set into the bottom of the integral unit. This permits the position of the trigger arm of the microswitch to be adjusted relative to the door by which it is actuated. The switch will initiate a cycle of the tape containing the recorded message thereon for broadcast to desired persons coming through the door. A notch provided on the magnet record tape together with a second microswitch having a feeler arm thereon stops the action of the player mechanism after a single cycle of the tape.
