Abstract
A coin-operated message display system used by the public under the control or censorship of a system operator. Typical uses are in skating rinks, convention halls, stadiums and other public gathering places. The user inserts a coin, dollar bill or combination thereof to activate the message insertion process. A joy stick controls movement of a cursor to position it over a letter or symbol to be selected in forming the message. An input button is depressed to make an individual selection so as to fill spaces on a matrix in sequential fashion. A delete button and a backspace button facilitate changes and corrections. When the desired message is completed, the user has the option of selecting how the message will enter and exit the display board. The user then presses the transmit button. This signals the system operator at the main central processing unit who reads the message and either approves or disapproves the message. If approved, the message is stored in a memory unit for display in time sequence. If disapproved, the message is deleted from the memory. The system operator can also enter messages and fixed advertising messages are also interspersed on the display panel.
