There was also a problem that the business mileage was counted. As a result, the drivers either had to pay for the subcommittee, or each time they made a request via radio to the headquarters asking for exemption. In addition, there were other inconveniences in operation management, such as forgetting to switch to rental mode after a passenger boarded the vehicle and driving in empty mode.

An object of the present invention is to provide a taxi meter that can reliably switch from payment mode to empty mode after fare settlement is completed, thereby solving the problems in operation management. is to provide.

Connected to F22 and the output terminal of the first JKFF27,
When H level signals are output from both circuits 22 and 27, an H level signal is output to the transistor 41. The transistor 41 is made conductive by the H level output signal from the AND circuit 23, and its collector current causes the buzzer 15 to emit a warning sound.

Next, the operation of the taximeter constructed as described above will be explained.

Now, when this taximeter is running in the empty car mode by pressing the empty car key 5, the second JKFF28 outputs an H level signal, so the first JKFF27 and R
The output signal of 8FF22 becomes L level, and AND circuit 2
The output signal of No. 3 also becomes L level.

When a passenger is on board and the vehicle is traveling in the rental mode by pressing the rental traveling key 4, the output signal of the third JKFF 29 becomes H level, the rental traveling lamp is lit, and the fare calculation circuit 36 is activated. Calculation of tolls based on distance traveled will begin. At the same time, the output signals of the first and second JKFFs 27 and 28 become L level based on the output signal of the same JKFF 29, so the empty car lamp 11 is turned off and the A
The output signal of the ND circuit 23 also becomes L level.

When the car arrives at the destination in this state and the payment key 2 is pressed, the output signal of the first JKFF 27 becomes H level and the payment lamp 8 is turned on.

Then, when the payment is completed and the passenger gets out of the car, and the photoelectric switch 19 is closed or the seat switch 16 is opened, the output signal of the OR circuit 17 becomes H level, so the transmission circuit 20 transmits the H level signal for a prescribed period of time. As the output signal of the transfer circuit 20 falls from the H level to the L level, the output signal of the R3FF 22 also goes to the H level.

Therefore, when a passenger gets out of the car with the payment mode set by pressing the payment key 2, the output signals of the R3FF 22 and the first JKFF 27 both become H level after a predetermined time, and in this state, the H level output signal from the AND circuit 23 As a result, the transistor 31 becomes conductive and the buzzer 15 emits a warning sound.

Based on this warning sound, when the driver presses, for example, the empty car key 5, the output signal of the second JKFF 28 becomes H level and the empty car lamp 11 is lit, and at the same time, the second JKFF 28 turns on the empty car lamp 11.
Since the output signal of the first JKFF 27 becomes L level based on the output signal of the KFF 28, the payment lamp 8 is turned off and the warning sound by the buzzer 15 is stopped.

Also, when the driver presses the extra key 3 based on the warning sound, the output signal of the fourth JKFF 30 becomes l-level.
Even when the output signal of the first JKFF27 becomes L level and the warning sound is stopped and the pick-up key 6 is pressed, the fifth JKFF27
Due to the H level output signal of KFF31, OR circuit 26
The output signal of R8FF22 becomes H level, the output signal of R8FF22 becomes L level, and the warning sound is stopped.

When driving in empty vehicle mode with a passenger on board, if you press the rental travel key 4 or the premium key 3 to drive, one of the corresponding lamps 3 and 4 will light up and the fare calculation circuit 36 will start. Calculation of the predetermined fares will start, but if you forget to operate the rental travel key 4 or the premium key 3 and start in the empty vehicle mode, an H level will appear at the input terminal T18 of the AND circuit 38 when there are passengers on board. When the signal is input, the traveling pulse detection circuit 39
outputs an H level signal a predetermined time after starting, so the AND circuit 38 outputs an H level signal after a predetermined time after starting.
1. : Outputs an H level signal.

Based on the output signal, the clock circuit 40 determines whether or not the current time is within the charge surcharge time. If it is outside the surcharge time, the clock circuit 40 sends an H level signal to the J terminal of the third JKFF 29 at the output terminal T20. If it is within the extra time, an H level signal is output from the output terminal T21 to the J terminal of the fourth JKFF 30.

Therefore, even if you forget to operate the fare running key 4 or the premium key 3 after loading a passenger, the fare calculation circuit 36 will switch to the fare running mode or the premium mode after a predetermined time depending on the time. A predetermined fee is accumulated.

As described above, when a passenger gets off the taxi meter with the payment mode set by pressing the payment key 2, the buzzer 15 emits a warning sound after a predetermined time to prompt the driver to switch from the payment mode to another mode. As a result, it is possible to prevent the driver from driving in payment mode after dropping off a passenger, and even if the driver forgets to switch from empty mode to rental mode or premium mode when loading a passenger and starting the vehicle. It is possible to automatically switch to a predetermined mode at that time.

Further, in the embodiment described above, the presence or absence of a passenger in the payment mode was detected in order to sound the buzzer 15, but a configuration may also be adopted in which a running signal in the payment mode is detected.

Furthermore, a lamp may be flashed as a warning device instead of the buzzer 15.

Effects of the Invention As detailed above, the present invention can prevent inconveniences in operation management, since it is possible to prevent the vehicle from traveling in the payment mode after dropping off a passenger, and from traveling in the empty mode after picking up a passenger. It exhibits excellent effects that can eliminate problems.
