Abstract
An image forming apparatus controls a general-purpose numerical key unit so as to maintain a state in which a NumLock LED is turned on in the case where a connecting cable of the general-purpose numerical key unit including a NumLock key capable of selectively switching, in a case that the general-purpose numerical key unit is connected to an information processing device including a display screen, a condition when the information processing devices processes an inputted key signal, between a first processing condition in which the key signal is processed as information on a numerical value and a second processing condition in which the key signal is processed as information for moving a cursor displayed on the display screen, and the NumLock LED capable of notifying a user of that the first processing condition is set for the information processing device by being turned on is connected to a connecting portion (step S15).
