Abstract:
1. A communication system comprising a first communication device and a second communication device, the first and the second communication devices being disposed in a predetermined distance range and positional relationship and performing communication between each of them, the first and the second communication devices comprising: a first transmission unit and a second transmission unit that are disposed respectively on bodies of the first and the second communication devices and wirelessly transmit predetermined information to each other, and the first communication device further comprising: a first reception unit that is disposed in a position where the first reception unit is capable of communicating with the second transmission unit and receives second information that has been transmitted from the second transmission unit; and a first control unit that controls the first communication device such that, when communication becomes possible between the first reception unit and the second transmission unit, the first reception unit receives the second information, and such that, when communication becomes possible between the first transmission unit and the second reception unit, the first transmission unit transmits first information, wherein the first communication device and the second communication device are independently movable, wherein communication becomes possible between the first reception unit and the second transmission unit when the second communication device receives a transmission permission signal that is sent by the first communication device in response to a transmission request signal that is sent by the second communication device, and wherein communication becomes possible between the first transmission unit and the second reception unit when the first communication device receives a transmission permission signal that is sent by the second communication device in response to a transmission request signal that is sent by the first communication device, a first acceleration detection unit which detects acceleration of a movement, wherein when the acceleration comprises a predetermined state, information that corresponds to the predetermined state is transmitted, when registering the predetermined state, a first receiving unit which receives a designation of a type of information that is to be transmitted a first storage unit which correlates and stores the predetermined state of the detected acceleration and the type of the information wherein the first control unit controls the first communication device such that, when the predetermined state of the acceleration and the type of the information are correlated and stored in the first storage unit and acceleration is detected by the first acceleration detection unit and the predetermined state of the acceleration corresponds to a state of acceleration that is stored in the first storage unit, the type of the information that corresponds to the state of the acceleration is read from the first storage unit and the type of the information is transmitted with respect to the second communication device.
