Abstract: In a turn management system (1000), whether or not input to an input device (115) is not performed for a predetermined period of time is determined, and a standby screen is displayed when it is determined that the input to the input device (115) is not performed for the predetermined period of time. At the time, a first standby screen is displayed when there is turn waiting in a waiting list, and a second standby screen is displayed when there is no turn waiting in the waiting list. Thus, unneeded issuance of a numbered ticket can be suppressed, and operation interruptions of a worker or the like can be reduced.

Abstract: By a scroll operation, at a lower part of a waiting list L1, customers of reception numbers “9”-“11” not displayed in FIG. 4A are displayed. At an upper part of the waiting list L1, an arousing alert AT1 (“there are customers waiting above” or the like) is displayed such that it is recognized that there are customers (specifically, the customers of reception numbers “1”-“3”) who are hidden outside the screen and are invisible.
