a first function control circuit configured to execute a first function; and
a processor;
wherein the processor is configured to:
establish a wireless connection with a terminal device upon request for the wireless connection from one of the wireless communication device and the terminal device,
query, upon establishment of the wireless connection with the terminal device, the terminal device with which the wireless connection is established to check whether a first application program for causing the wireless communication device to execute the first function is in a state of being executed or run by the terminal device,
maintain or cut off the wireless connection with the terminal device based on a response from the terminal device to the query,
after a predetermined period has elapsed since a time at which the wireless connection with the terminal device is maintained based on the response from the terminal device to the query, re-query the terminal device with which the wireless connection is maintained, and cut off or continue to maintain the maintained wireless connection based on a response from the terminal device to the re-query, and
identify, as a connection-prohibited terminal device, a terminal device not responding to at least a predetermined number of queries, cut off the wireless connection with the connection-prohibited terminal device, and prohibit the connection-prohibited terminal device from reconnecting to the wireless communication device within a connection prohibition period, the connection prohibition period being updated in accordance with a number of times that the wireless connection has been cut off.
