Disclosed is a slot-type concurrent output signal generator adapted to enable a minimum number of operators to concurrently inspect the screen quality of various display devices in a single process. The slot-type concurrent output signal generator can shorten processes regarding a signal inspection on the production line of various display devices (e.g. CRT, LCD, PDP). The slot-type concurrent output signal generator can be advantageously used for cell-line type or U- line type production so that a minimum number of operators constituting an independent line can concurrently inspect various output terminals on a desired inspection condition in a single process without having to modify the operation of the signal generator. This reduces the cost and improves the productivity.
