A method of detecting an input of an input marking apparatus includes generating and outputting a number signal to be written to the input marking apparatus, detecting the input marking apparatus in which the number signal is written, by detecting a response signal output from the input marking apparatus, and detecting a position of the input of the input marking apparatus of which the response signal is detected.
