<p>The kiosk incorporates, screens, television monitors or viewers which permit automatic closed circuit broadcasting of black and white colour films, in one or several languages transmitted or recorded by a videocassette, videodisc or other modern technique. The kiosk permits transmission of the audio visual medium on all of its faces from 1 metre above ground level to 5 metres or more. A supply of electrical current is all that is required for fully automatic operation and diffusion of the audio visual systems. The screens which are situated at the highest levels are tilted downwards to permit better viewing. Heat generated in the kiosk from the electrical and audio visual equipment is removed by a ventilating or air conditioning system which maintains the temp. inside the kiosk at the optimum for efficient working of the audio visual systems.</p> |
