<p>PURPOSE:To correctly transfer operation information without loading/unloading, transportation, or other work. CONSTITUTION:A management device 6 installed at a taxi service office conducts information processing, such as summing up, based on mileage, a fare, and other operation information, and a communication control device 5 transmits an instruction radio wave 7 equipped with transmission instruction information in order to receive the operation information and transmits a question radio wave 1 at the same time. A communication device 3, when it receives the question radio wave 1 and the instruction radio wave 7, reads the operation information stored in the internal memory of a fare meter 2 and, at the same time, modulates the question radio wave 1 according to the operation information to transmit it as a response radio wave 4. Then, the communication control device 5 receives the response radio wave 4 to regenerate the operation information and substitute each information of an operation device for a specified discriminant to discriminate correctly regenerated operation information from incorrectly regenerated operation information. The regenerated operation information, when it is correct, is outputted to a management device 6, and when it is incorrect, the communication device 3 is made to transmit the response radio wave again.</p> |
