In steps S2 and S3, reception of the vehicle code from the setting device 2 is on standby (N in steps S2 and S3).

On the other hand, in steps T1A and T1B showing the setting device-side processing operation, the fee-based data and the vehicle code are input using the keyboard 23 and the like. Then, the input fee system data and vehicle code are temporarily stored in the RAM 202.

N in step T4).

When the taxi meter 1 in the communication mode and waiting for the reception of the vehicle code receives the vehicle code, the taxi meter 1 proceeds to step S4 to detect the coincidence (Y in steps S2 and S3). In step S4, the vehicle code stored in the EEPROM 11 is compared with the vehicle code received via the communication device 15, and if the codes are detected as coincident, the process proceeds to step S5 (step S4). Y), otherwise
Returning to step S1, the state of the switch 14 is detected. If it is determined in step S1 that the mode is not the setting mode from the state of the switch 14, a series of processing ends there (N in step S1). This step S4 corresponds to a vehicle code coincidence detecting means in the claims. In step S5, a fee system data request signal is transmitted via the communication device 15 in order to acquire the fee system data from the setting device 2, and the taxi meter 1 waits for the fee system data reception in steps S6 and S7. The state is entered (N in step S6 and step S7). Step S5
Corresponds to the charge data requesting means in the claims.

When receiving the charge data request signal, the setting device 2 in the charge data request signal waiting state shifts the processing to step T5 to transmit the charge data (step T3, Y in step T4). In step T5, the fee-based data stored in the RAM 202 is read and transmitted to the taxi meter 1 via the communication device 22. After the transmission of the charge system data, the setting device 2 performs steps T6 and T7.
In the setting end signal waiting state (step T

When the taxi meter 1 in the charge data reception waiting state receives the charge data via the communication device 15, the taxi meter 1 shifts the processing to step S8 to write the received charge data (steps S6 and S7). Y). Then, in step S8, the received fee-based data is written into the EEPROM 11, and
In step S9, the write operation in step S8 is performed until a predetermined switching operation indicating the release of the setting mode is performed by the mode switch 14 (step S8).
6, Y of step S7, step S8 and step S9
N). Step S8 corresponds to a charge data writing unit in the claims. And the mode changeover switch 1
When a predetermined switching operation indicating the release of the setting mode is performed by Y (Y in step S9), the communication mode is released, and a setting end signal is transmitted to the setting device 2 via the communication device 15 in step S10. Is done.

The setting device 2 in the setting end signal waiting state
When this setting end signal is received, a series of fee-based data transmission processing ends (Y in step T6 and step T7).

As described with reference to FIG. 4, since the fee-based data transmitted from the setting device 2 by radio is received and written into the EEPROM 11, the conventional method is used when rewriting the fee-based data. This eliminates the need for cumbersome work, and allows flexible handling of fee revisions and the like. Therefore, the data renewal delivery time and man-hours are reduced, so that the fee-based revision cost can be significantly reduced.
In addition, since the operation of writing the initial data is simplified by using the wireless communication, the number of steps for manufacturing a new taxi meter is also reduced. Note that writing of the fee-based data by wireless requires setting the communication mode by the normally-sealed mode changeover switch 14.
Safety is also ensured. Further, based on the detection of a match between the vehicle code wirelessly transmitted from the setting device 2 and the own vehicle code in step S4 prior to the transmission of the fee system data, the setting device 2 is requested to transmit the fee system data. Therefore, erroneous writing of the fee-based data is prevented. As a result, the safety at the time of writing the fee-based data is further improved due to a synergistic effect with the mode changeover switch 14.

FIG. 5 is a flowchart showing another example of the processing operation performed between the taxi meter and the setting device related to the setting of the fee system data according to the present invention. The flowchart shown in FIG. 5 is based on the setting device 25 automatically responding to the insertion of the setting card 25 in which the vehicle code and the fee system data are recorded in advance into the card reader 24, based on the vehicle code and the fee system data. 2 shows an example in which communication between the taxi meter 1 and the taxi meter 1 is performed. However, when the card is mounted, the taxi meter 1 must be in the communication mode.

Be able to respond flexibly to revisions.

According to the fourth aspect of the present invention, the present invention is effective not only when rewriting the fee-based data but also when newly writing into the fee-based data storage means 11B. That is, since the wireless system is used to write the fee-based data, the writing operation is simplified, and the production delivery date of the taxi meter 1 is shortened.

According to the fifth aspect of the present invention, since the mode setting means 14A is the mode changeover switch 14 which is sealed to prevent unauthorized rewriting by a third party, the security of the charge system data is further improved. .

According to the sixth aspect of the present invention, since the fee-based data is input on the setting device 2 side and transmitted by radio, the complicated work conventionally performed when rewriting the fee-based data is unnecessary. In other words, it becomes possible to flexibly respond to a fee revision or the like. Therefore, the data renewal delivery time and man-hours are reduced, so that the fee-based revision cost can be significantly reduced. Further, since the operation of writing the initial data is simplified by using the wireless communication, the number of steps for manufacturing a new taxi meter is also reduced.

According to the seventh aspect of the present invention, since the setting device 2 has the vehicle code input means 23B, the input vehicle code is wirelessly transmitted prior to the transmission of the fee-based data. The taxi meter 1 can detect the coincidence with the vehicle code, thereby preventing erroneous writing of the toll system data. As a result, the security when writing the fee-based data is improved.

According to the eighth aspect of the present invention, the charge data input means 23A and the vehicle code input means 23B.
