Publication number: 20060241571Abstract: In an energy irradiation device, individual identification information provided to an energy transmitting and irradiating section is acquired, and a date and time when the individual identification information has been acquired is recorded. Next, the acquired individual identification information is associated with at least one of an output signal of an output operating section and a date and time when the information has been recorded to store the information. When new individual identification information is acquired, the new individual identification information is searched from the individual identification information stored in the memory.
