Abstract
PURPOSE:To give compatibility to an input state by outputting a signal equivalent to the output signal from a first input means to an electronic controller synchronously with the key scan signal outputted from the electronic controller by the output signal from a second input means. CONSTITUTION:An interface circuit 2 is provided to enable real-time conversion. That is, the interface circuit 2 converts data and synchronizes the output with the scan signal by only outputting the current input by means of an input device 1 state. When this operation is viewed from the side of the input device 1, the input device 1 outputs data to the interface circuit 2 with delay time after the input, but key inputs is not erroneously recognized if synchronization is acquired in the interface circuit level because the operation which changes the scan signal to scan all keys is repeated at intervals of a certain time to check the key input in case of the scan system.
