PROBLEM TO BE SOLVED: To prevent visual recognition of a change performance by a specific performance from being interrupted.SOLUTION: A change performance (e.g., a performance in which a reservation change pattern performance is executed and a mode of a reservation display is changed from a normal display mode to a special display mode) in which a display mode of the reservation display is changed to a mode (e.g., a special display mode (a red round-shape display)) different from a normal mode (e.g., a normal display mode (a blue round-shape display)) can be executed, and a specific performance (e.g., a step-up notice performance) can be executed. Also, when the change performance is executed in a variable display of identification information in which a variable display period is shortened, execution of the specific performance is restricted. In addition, even when the change performance is not executed, the display mode of the reservation display can be changed to a mode different from the normal mode. |
