ABSTRACT:
A coin operated elapsed time apparatus capable of receiving coins at any time, even while counting down, in order to increase the time remaining and therefore avoid the additional costs required to activate the system again if the service or use of apparatus required that more time be rented or purchased. The apparatus continuously displays the time remaining and gives a warning a predetermined period of time before the time runs out, thereby enabling the purchase of additional time and displaying the sum of the elapsed time remaining and the additional time purchased immediately after the insertion of an additional coin.
