The device according to any one of claims 1 to 4, wherein the movement history includes position information acquired by the communication unit. A plurality of the object files exist for each of the predetermined characters, and includes compatibility between the predetermined characters,
The device according to any one of claims 1 to 5, wherein the probability data varies in accordance with compatibility between the predetermined characters included in the object file.   The device according to any one of claims 1 to 6, wherein the device is installed in a publicly available place and communicates with an external device. Communication in which a predetermined character moves between the first device and the other device when the first device and another device different from the first device perform short-range communication using a radio signal A control method in a system,
The first device includes data of the predetermined character from the second device, and a movement history of the predetermined character moving through a plurality of devices until the predetermined character reaches the second device. An object file receiving step for receiving the object file;
A storage step in which the first device stores the object file received in the object file reception step in a first storage unit;
A first display control step for causing the first device to display the predetermined character on a first display means based on the object file stored in the storage step;
A first receiving step in which the first device receives a predetermined radio signal transmitted intermittently from the third device at regular intervals ;
When the predetermined character is displayed on the first display means and the predetermined wireless signal is received in the first receiving step, the first device determines whether the predetermined character can move. based on the probability data for determining a determining step of determining whether to move to the third device said object file from said first device,
When the first device determines to move the object file from the first device to the third device in the determining step, the predetermined character data and the predetermined character are A transmission step of transmitting to the third device an object file including a movement history obtained by adding a movement history in the first device to a movement history up to the second device;
A deletion step of deleting the object file stored in the first storage means after the first device has transmitted the object file in the transmission step;
A second receiving step in which the third device receives the object file from the first device;
A storage step in which the third device stores the object file received in the second reception step in a second storage unit;
A control method for a communication system, comprising: a second display control step in which the third device displays the predetermined character on a second display unit based on the object file stored in the second storage unit.
