Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fare meter installed in a vehicle by a taxi agent or a driving agency agent.

[0002]

2. Description of the Related Art For example, in a taxi meter, a traveling pulse from a traveling sensor is processed by fare data for calculating a fare, and a fare is calculated and displayed. This tariff data is generally obtained from the E ² PROM (Electrically Erasable Programmab) stored in the taximeter.
le Read-Only Memory), this E ² P
Each time the fee system is revised, the ROM will be replaced with a new E ² PROM storing the revised fee system data. Actually, the revised tariff data is stored in E
² Prepare a taximeter with a built-in PROM before revision, and replace it with a new taximeter before and after the revision date.

However, since it is not possible to replace all taximeters all at once, in practice, the taximeters should be replaced little by little from the time when the tariff revision date is as close as possible. It is usually started. For this reason, in the past, even after the revision of the fee system, E ² PROM
In some cases, the taxi meter that corresponds to the old tariff system before the exchange will be installed, and in that case, the old tariff displayed on the taxi meter will be converted to the new tariff based on the revised tariff system using the conversion table. Then, the fare was collected from the passengers. However, if you use the conversion table to collect tolls, you may forget to use the conversion table or make a mistake and collect the wrong amount of money, which may cause unnecessary trouble with passengers. Was there.

In order to eliminate the above-mentioned problems, it is possible to automatically switch between different fare calculation methods before and after the revision of the fare system without replacing the taximeter or the E ² PROM mounted therein. As a conventional technique for performing such automatic switching, it is possible to automatically switch between a fare tariff with a different tariff and a late night early morning surcharge tariff, for example, Japanese Patent Laid-Open No. 47-3493. There is a taximeter disclosed in JP-A-5-324962.

Specifically, in the taximeter of Japanese Patent Laid-Open No. 47-3493, at the time of switching rates at night or on weekends, a switching signal is transmitted by a relay operation of a time circuit of a central control unit arranged in a business office or the like. It is sent out wirelessly, and each taximeter receives this switching signal to change the connection state of the internal switching contact, and due to this change in the connection state, the rate applicable to the normal time zone and the day of the week and, for example, midnight It is configured to switch the rate applied to the time of day and the day of the week. On the other hand, in Japanese Unexamined Patent Publication No. 5-324962, the tariff button is not operated when the time period during which the rate different from the rate applied up to now is applied as the time elapses during business travel. Also, the fare rate applied to the calculation of the boarding fare is automatically switched to the fare rate according to the time based on the current time of the clock means.

[0006]

As described above, both of the taximeters described above are intended to deal with a plurality of tariffs that differ depending on the time of day, the day of the week, and the like.
When changing the applied rate depending on the time of the day, the day of the week, etc., it is usual to add or discount the normal rate at a predetermined rate, as in the current late night and early morning premium rate system. And, in the case of surcharge or discount of the normal fare, the boarding fare is calculated once at the normal fare rate, and this boarding fare is surcharged, or the discount is calculated and the fare is increased or discounted. Or the traveling pulse from the traveling sensor that is the basis of the calculation of the boarding fare is modulated to raise or lower the frequency, and then the extra charge or discounted fare according to the normal fare Is calculated. Therefore, if the revised tariff system is simply a premium or a discount to the pre-revision tariff system, both taxi meters described above are applied to apply the tariff system from before the revision. There is a possibility that it can respond to the revision of.

However, neither of the taxi meters described above is intended to deal with the revision of the fare system as described above. Therefore, for example, the basic distance traveled with the basic fare as the boarding fare, the number of distances after that to which the fare is added, or the amount of the intercepting fare, the application conditions for the combined time-distance system (speed, unit time, etc.) In the case of a revision of the fare system that changes, the fare after the revision is calculated based on the fare calculated by the fare system before the revision, and the travel pulse from the travel sensor is modulated as described above. Therefore, it is impossible to calculate the revised boarding fare. That is, there is a problem in that it is impossible to apply the above-mentioned taxi meters to the revision of the tariff system even before the revision of the tariff system.

Further, in both taximeters of JP-A-47-3493 and JP-A-5-324962,
There is room to deliberately shift the current time of the time circuit and clock means to shift the rate switching timing so that the boarding fee is collected at a higher amount than the original boarding fee,
There was a problem that it was hard to say completely in preventing fraud and the disadvantage of passengers. The problem of changing the tariff system data due to the revision of the tariff system described above may also occur in a tariff meter installed by a driving agency on a vehicle for parallel driving and used for calculating a driving agency fee. Is.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to change the charge system data accompanying the revision of the charge system from the stage before the revision. It is to provide a fare calculation meter, and further to provide a fare calculation meter for a vehicle that enables switching between the old and new fare systems applied to calculate the fare at an accurate time. To do.

[0010]

In order to achieve the above object, the present invention, as shown in the basic configuration diagram of FIG. 1, calculates a boarding fare for a vehicle in which the fare varies according to the business operation of the vehicle. A meter for calculation, which is a clock means 123 for managing the current date and time, and a revised date and time data holding means 117A for retaining the revised date and time of the fare system which is the basis for calculating the boarding fare.
And a pre-revision fare system applied to the calculation of the boarding fare before the revision date and time and a post-revision fare system applied to the calculation of the boarding fare after the revision date and time. 117B, the before / after revision determining means 119A that refers to the current date and time of the clock means 123 at the start of the business operation of the vehicle, and determines whether the current date and time is before or after the revised date and time, and the before / after revision determining means 119.
Based on the determination result of A, the pre-revision fee system is selected when the business travel of the vehicle is before the revised date and time, and the post-revision is selected when the business travel of the vehicle is after the revised date and time. And a selection unit 119B for selecting a fare system, and calculates the boarding fare by applying the fare system selected by the selection unit 119B between the pre-revision and post-revision fare systems when the vehicle is in business travel. It is characterized by doing so.

Further, the present invention further comprises a non-volatile charge revision data storage means 117C, and when the before / after revision discriminating means 119B first discriminates that the present date and time is after the revision date and time, the revision is made. The charge-revision data indicating the application of the post-charge system is converted into the charge-revision data storage means 117.
It is supposed to be stored in C. Furthermore, according to the present invention, when the before / after revision discriminating means 119B first discriminates that the current date and time is after the amended date and time, the alarm output means 121 for outputting an alarm notifying the application of the post-revision fee system is provided. I decided to prepare more.

Further, according to the present invention, the date and time correction means 125 and 129 for correcting the current date and time managed by the clock means 123.
~ 137, and the date / time adjusting means 125, 129 ~ while the selecting means 119B selects the pre-revision fee system.
A date / time correction prohibiting means 119C for prohibiting the correction of the current date / time by 137 is further provided. further,
According to the present invention, cumulative data including the number of times the vehicle has been operated, the total amount of money calculated when calculating the boarding fare, and the number of times thereafter is used as long as the selecting unit 119B selects the pre-revision fare system. The pre-revision cumulative data holding unit 119ba which holds while sequentially updating the data and the cumulative data,
A revised cumulative total data holding unit 119bb which is sequentially updated and retained while the selecting unit 119B is selecting the revised fare system, and a display for displaying the boarding fare and cumulative data before and after the revision. And means 103.

[0013]

According to the present invention, at the start of business operation of the vehicle,
If the current date and time managed by the clock means 123 is before the revision date and time of the fee system held by the revised date and time data holding means 117A, the pre-revision fee in the fee system data holding means 117B selected by the selecting means 119B. If the current date and time is before the revision date and time of the fare system, the data of the pre-revision fare system in the fare system data holding unit 117B selected by the selection unit 119B is applied. Since the boarding fare is calculated by changing the fare system data, it is not necessary to change the fare system data due to the revision of the fare system once the use of the meter is stopped immediately before the date and time of the revision. That is, it is possible to sequentially perform the steps well before the revision date and time.

Accordingly, the vehicle is operated with the vehicle equipped with the meter corresponding to the pre-revision fare system, and the boarding fee is settled according to the fare system after the revision based on the conversion table. There is no need to carry out work that would cause unnecessary troubles with passengers, such as conversion to a new fare, and collection of a wrong amount due to misuse or misconception of the conversion table.

Further, at the start of the business operation of the vehicle, the nonvolatile charge is determined when the before / after revision determining means 119B first determines that the current date and time managed by the clock means 123 is after the revision date / time of the charge system. By storing the fare revised data indicating the application of the revised fare system in the revised data storage means 117C, when the power supply to the fare calculation meter from the battery is cut off, the fare system will be set at that time. It is possible to retain as data whether the revision date and time has passed or not. Therefore, if the power supply from the battery is cut off after the charge revision date and time, the same revised tariff system as before the power supply cutoff can be reliably applied after the power supply is restarted. It is possible to reliably prevent the occurrence of the trouble that the pre-revision fee system will be applied again later.

Also, when the vehicle before and after the start of business operation, the before / after revision discriminating means 119B first discriminates that the current date and time managed by the clock means 123 is after the revised date and time of the charge system, the alarm output means 121. By outputting an alarm notifying that the post-revision toll system is applied, it becomes possible to thoroughly inform the crew members and passengers of the vehicle that the toll system has been switched. Furthermore, the date and time correction means 125,129
~ 137 management of the clock means 123, the correction of the current date and time, by the date and time correction inhibiting means 119C, the selection means 11
By prohibiting 9B while selecting the pre-revision fee system,
By modifying the current date and time before the revision of the fare system, the change from the pre-revision fare system to the post-revision fare system applied to the calculation of the fare will be changed before and after the actual revision date and time, and the original boarding fare It is possible to prevent the fraud and the disadvantage of passengers from occurring by eliminating the room for collecting the fare at a higher price.

In addition, among the accumulated data including the number of times the vehicle has been operated, the accumulated amount of money calculated when calculating the boarding fare, and the number of times thereafter, the accumulated amount only while the selecting unit 119B selects the pre-revision fee system. The data is held while being sequentially updated by the pre-revision cumulative data holding unit 119ba, and the post-revision cumulative data is retained only for the cumulative data while the selecting unit 119B is selecting the post-revision fee system. The means 119bb sequentially updates and retains the accumulated data before and after the revision of the charge system after the revision of the fee system, and the accumulated data before revision 11 holding means 11
Retained data of 9 ba and the revised accumulated data holding means 11
It is possible to confirm individually on the display means 103 for displaying the boarding fare by using the held data of 9 bb.

The E ² PROM 117 and the RAM 11 are
Flags FA and Fa in each charge revision flag area of 9b are
If the tariff revision date and time is reached in the empty tariff state, it will be "1" at that time, while the tariff revision will be made in the operating tariff (rental rate, 30% increase, and each tariff of the intercepting vehicle). When it reaches the daytime, it becomes "1" in the state in which it shifts from the business tariff state to the empty tariff, and becomes "0" until then. Also, the subsequent flag F
b is "0" while the boarding fare is the basic fare, and is "1" after the first and subsequent fare is added to the boarding fare.

Further, the flag F in the payment flag area
c is "1" when the taxi meter 1 is in the payment tariff, and other business tariffs (wage, 30% increase,
In addition, it is “0” in a state in which each tariff of an intercepting vehicle or an empty vehicle tariff is present. Further, the flag Fd in the 30% increase flag area becomes "1" when the taxi meter 1 is in the 30% increase tariff, and other business tariffs (rental, 30% increase, and tariffs of the intercepting vehicle) and empty tariffs. It becomes "0" in the state. Further, the count value C of the travel pulse counter is input from the travel sensor to the CPU 119a after the fare is added to the boarding fare during the business tariff and before the next fare is added to the boarding fare. It shows the number of pulses.

When the above-mentioned initial setting is completed, the E ² PROM

As is clear from the above description, in this embodiment, the before / after revision discriminating means 119A in the claims is composed of step S69 in the flowchart of FIG. 7 and step S91 in the flowchart of FIG.
Further, in this embodiment, the selecting means 119B in the claims is composed of step S71 in FIG. 7 and step S93 in FIG. 8, and the date and time correction inhibiting means 119C is composed of step S49 in FIG. .

Next, the operation (action) of the taximeter 1 of the present embodiment having the above-mentioned structure will be described. First,
At the time of pricing of the revised is determined, at the time of the well before than the revised date and time, and remove the taxi meter 1 from the taxi by the number of degree that there is no hindrance to business, bring to the manufacturing plant or the like, old and new E ² Replace the PROM 117. Here, in the old E ² PROM 117, as the pre-revision rate system data, the data of the previous past rate system used before the change to the current rate system is written, and the revised rate system data. As the current fee system data is written. Further, as the date and time of the revision, the date and time at which the above-mentioned immediately previous charge system is changed to the current charge system are written. Further, the flag FA in the charge revision flag area is "1" because the previous charge system immediately before has been already changed to the current charge system.

On the other hand, in the new E ² PROM 117,
As the charge system data before the revision, the current charge system data is written, and as the revised charge system data, the new charge system data to be revised later is written. Further, as the date and time of revision, the date and time at which the above-mentioned current charge system is changed to the new charge system are written. Furthermore, the flag F in the charge revision flag area
A is “0” because the current fee system is still used and the transition to the new fee system has not been completed.

Then, when a taxi equipped with the taxi meter 1 that has been replaced with the new E ² PROM 117 is operating, when the total button 115 is operated in the empty tariff state, the sub display area of the charge display section 103 is displayed. 103b
In the index data before price revision stored in the index data area before revision, the indexes of item numbers 3 to 10 in the system data corresponding to the number of times the cumulative button 115 is operated are displayed.

When the total button 115 is continuously operated for 5 seconds or longer, the index displayed in the sub display area 103b is revised from the index in the index data before the price revision stored in the index data area before revision. Switch to the index of the same item number in the post-revision index data stored in the post-index data area, and with the index in the post-revision index data displayed, press the cumulative button 115 for 5 seconds or longer. When the operation is continued, the index of the next item number in the index data after the price revision is once displayed in the sub display area 103b, and then the index of the same item number in the index data before the price revision is displayed in the sub display area 103b. The display switches. It should be noted that, when 15 seconds have passed since the last operation of the cumulative total button 115 was finished, the index display in the sub display area 103b is automatically cleared, that is, erased.

Next, when the intercepting car tariff button 111 is operated, the intercepting car charge is displayed in the sub display area 103b of the charge display unit 103, and thereafter, before the fare tariff button 107 or the 30% increase tariff button 109 is operated. Then, when the empty vehicle tariff button 105 is operated, the display of the oncoming vehicle charge in the sub display area 103b is cleared, that is, erased. Also, when the fare tariff button 107 and the 30% increase tariff button 109 are operated, the basic fare is displayed as a boarding fare in the main display area 103a of the fare display unit 103, and at this time, the intercepting fare is previously displayed in the sub display area 103b. If it is displayed, the intercepting fare is continuously displayed in the sub display area 103b.

In the present embodiment, the displayed amounts of the intercepting fare and the boarding fare are displayed at the time when the first one of the intercepting tariff button 111, the fare tariff button 107, and the 30% increase tariff button 109 is operated. If the current date and time managed by 123 has not reached the revised date and time of the fee system stored in the revised date and time data area, the amount based on the pre-revision fee system will be applied, while the clock device 123 will manage it. When the present date and time has reached the revision date and time of the fee system stored in the revision date and time data area, the amount is based on the revised fee system.

Then, after displaying the pick-up charge and the boarding charge in the amount based on the pre-revision fee system, the empty car tariff button 105 is operated in the middle of the cancellation of the pick-up vehicle or when the business run is officially completed. If the current date and time managed by the clock device 123 reaches the revised date and time of the toll system stored in the revised date and time data area in the middle of the process, the intercepting fare displayed at that time is revised. It does not change to a later price, and the displayed amount of fare after that point does not change due to the revised fare system. Therefore, if the date and time of revision of the fare system is reached during a vehicle pick-up or during business travel, the vehicle will be canceled midway, or it will enter the regular business travel as it is and after the business travel ends. At that time
The charge system before the revision will be switched to the charge system after the revision. When the pre-revision fare system is switched to the post-reform fare system, the alarm buzzer 121 sounds for a predetermined period of time to notify the crew member that the fare system has been switched.

Further, in the taximeter 1 of this embodiment,
In the state of the empty vehicle tariff or the intercepting vehicle tariff, the correction instruction button 129, the numerical value change button 131, the feed button 133,
Also, by operating the set button 135, the current date and time managed by the clock device 123 is corrected. However, when the current date and time managed by the clock device 123 before the correction has not reached the revision date and time of the charge system stored in the revision date and time data area, the correction instruction button 129 and the numerical value change button 131, send button 133,
In addition, the operation of the set button 135 is invalidated, and therefore, the current date and time of the clock device 123 can be corrected only after the date and time when the fee system is revised.

This is intended to eliminate unnecessary or fraudulent correction of the current date and time by the taxi crew. For example, a taxi meter with the E ² PROM 117 replaced can be used for taxi operations. It does not prevent even a regular time adjustment operation performed by a taxi company administrator who is authorized in advance when installing the taxi at a place. Therefore, as explained above, if these managers connect a dedicated external device such as a time adjuster to the taxi meter, the taxi meter 1 which has not reached the date and time of the revision of the tariff system can be installed in the taxi. Even at the time, the current date and time of the clock device 123 can be corrected by operating the external device.

As described above, according to the present embodiment, the buttons 107 for the fare tariff, the 30% increase tariff, and the intercepting tariff.
When the taxi starts operating by operating ~ 111, the current date and time managed by the clock device 123 is E ² P.
If it is before the revision date / time of the charge system stored in the revision date / time data area of the RAM 119b read from the ROM 117, the RAM 1 is also read from the E ² PROM 117.
The pre-revision fare system stored in the pre-revision fare system data area of 19b is applied to calculate the boarding fare, and if the current date and time is before the fare system revision date and time, the post-revision fare system data of the RAM 119b is calculated. The revised fare system stored in the area is applied to calculate the fare.

Therefore, it is not necessary to intensively replace the E ² PROM 117 immediately before the date and time of revision of the charge system, and therefore, after the date and time of revision, the pre-revision charge system is stored.
² Equipped with the taximeter 1 with the PROM 117 built-in, the taxi does business and eliminates the need to collect the fare using the conversion table, etc., eliminating the possibility of causing unnecessary trouble with passengers. be able to.

Although the alarm buzzer 121 and the structure for ringing the alarm buzzer 121 in this embodiment may be omitted, the fare system applied to calculate the boarding fare is revised from the fare system before revision. The alarm buzzer 121 sounds for a predetermined length of time at the time of switching to the later toll system, thereby informing and recognizing to the crew members and passengers that the revised toll system will be applied thereafter. It becomes possible.

In addition, the cumulative data before and after the revision of the charge system in this embodiment is displayed in the sub-display area 1 of the charge display unit 103.
The configuration for individually displaying on 03b may be omitted similarly to the alarm buzzer 121 and the like. However, with the provision of these as in the example, at the time when the fare system applied to calculate the fare is switched from the pre-revision fare system to the post-revision fare system, various types of pre-revision fare systems are being applied. R for accumulated data and various accumulated data while applying the revised tariff system
If stored individually in each index data area before and after the amendment of AM 119b, the cumulative data before and after the revision of the charge system can be individually displayed on the sub-display area 103b of the charge display unit 103, and sales information can be displayed. Will be collected separately before and after the revision of the tariff system.

Further, in the present embodiment, the flag FA is switched from "0" to "1" after the change of the charge system from the pre-revision charge system to the post-revision charge system is completed.
The charge revision flag area similar to 9b is set to E ² PROM 11
Although the configuration provided in No. 7 may be omitted, if this configuration is provided, the following further effects can be obtained. That is, for example, the power supply from the battery is cut off after the date and time of the revision of the charge system, and the contents of the charge revision flag area of the RAM 119b, which is in the state of "1" indicating the post-revision, disappears. , Even if it is reset to zero after the power supply is restarted, by checking the status of the flag FA of the E ² PROM 117, the pre-revision fee system is applied again after the revision date and time. Can be reliably prevented.

The configuration for backing up the state of the flag Fa in the charge revision flag area of the RAM 117b is not limited to the charge revision flag area of the E ² PROM 117 shown in the embodiment, but may be past the revision date of the charge system, for example. When the transition from the pre-revision to the post-revision fee system is completed, E
^{2 It is} possible to delete the data of the date and time of revision of the charge system in the PROM 117 and confirm whether or not the change of the charge system before and after the revision has been completed by the presence or absence of the data of the date and time of revision. Further, the charge revision flag area similar to the charge revision flag area of the RAM 117b is the E ² P
In addition to the ROM 117, a non-volatile memory (NVM) other than the ROM 117 may be provided and provided in the ROM 117. In any case, as long as the stored contents can be retained even when the power supply is cut off, It may be something like this.

Further, the timepiece device 12 in the present embodiment.
The configuration for prohibiting the correction of the current date and time managed by 3 during the application of the pre-revision fee system can be omitted as in the above configuration. However, if this configuration is provided, the current date and time managed by the clock device 123 becomes earlier than, for example, the actual date and time, and the revision date and time of the fee system appears to come earlier. This is advantageous because it is possible to prevent situations in which the difference from the later fee system is illegally or accidentally collected, which causes unnecessary troubles with passengers. .

In this embodiment, the case where the timepiece device 123 manages the current "year", "month", "day", "hour", and "minute" has been described. 123
Management is limited to "day" at the minimum, or if the revision of the fee system is at the end of the month, the beginning of the month, or the year-end and New Year holidays, or E
^{2 The} timepiece device 1 depends on how far back the revised fee system data of PROM 117 is rewritten from the date of revision.
Whether or not to sequentially add “year”, “month”, “hour”, and “minute” to the management contents of 23 is arbitrary. Furthermore, in the present embodiment, the taxi meter 1 mounted in a taxi has been described as an example, but the present invention is a fare calculation device in which a driving agency is installed in a vehicle for companion driving and calculates a fare for driving agency. Needless to say, it can be widely applied to various meters for calculating a boarding fare that fluctuates as the vehicle travels.

[0076]

As described above, according to the present invention, a vehicle fare calculation meter for calculating a fare whose amount of money fluctuates as the vehicle is operating, and a clock means for managing the current date and time. And a revision date and time data holding means for holding the revision date and time of the fare system that is the calculation standard for the boarding fare, a pre-revision fare system applied to the calculation of the fare before the revision date and time, and after the revision date and time A charge rate data holding means for holding each data of the revised charge rate applied to the calculation of the boarding charge, and the current date and time of the clock means at the start of the business operation of the vehicle are referred to, and the current date and time is the revised date and time. Based on the before-and-after revision discriminating means for discriminating between before and after and the discrimination result of the before-and-after revision discriminating means, when the business travel start of the vehicle is before the amended date and time, the pre-amendment charge system is selected, and And selecting means for selecting the post-revision fee system when the start of both business trips is after the revised date and time, and when the vehicle is in business travel, the selection is made from both the pre-revision and post-revision fee systems. The fare system selected by the means is applied to calculate the boarding fare.

Therefore, it is not necessary to temporarily stop the use of the meter immediately before the date and time of revision to change the fee system data due to the revision of the fee system, and the stage after the revised fee system is decided,
In other words, it will be possible to carry out sequentially from the stage well before the revision date and time, and by doing this, we will operate with the vehicle equipped with the meter compatible with the pre-revision fee system and settle the boarding fee before the revision. The amount calculated by the fee system is converted into a new fee by the revised fee system using the conversion table.
It is possible to eliminate the need to perform work that causes unnecessary troubles with passengers by collecting the wrong amount of money due to forgetting to use the conversion table or making a mistake.

In addition, the discrimination before and after the revision of the fee system is
The clock means and the before / after revision discriminating means can be used inside the meter, and all signals related to the switching of the fare system applied to calculate the fare can be exchanged inside the meter. As much as there is no transmission / reception, we eliminate the factors that cause incorrect switching of the applicable charge system, such as control errors related to signal input from the outside and signal output to the outside, and noise mixing in the transmission / reception signal. Thus, it is possible to perform a reliable charge system switching at an accurate time.

Further, according to the present invention, a non-volatile charge revised data storage means is further provided, and when the before / after revision determining means first determines that the current date and time is after the revised date and time, the revision is performed. Since the charge-revision data indicating the application of the post-charge system is stored in the charge-revision data storage means, for example, when the power supply from the battery is cut off after the charge revision date and time, It is possible to reliably apply the same revised charge system as before the power supply was cut off after the restart, and it is possible to reliably prevent the occurrence of troubles in which the pre-revision charge system is applied again after the date and time of revision.

Further, according to the present invention, when the before / after revision discriminating means first discriminates that the current date and time is after the amendment date and time, an alarm for outputting an alarm notifying the application of the post-revision fee system is issued. Since the output means is further provided, the warning output from the warning output means can inform the crew members and passengers of the vehicle that the revised toll system has begun to be applied.

Further, according to the present embodiment, the date and time adjusting means for adjusting the current date and time managed by the clock means, and the date and time adjusting means by the date and time adjusting means while the selecting means selects the pre-revision fee system. Since it is configured to further include a date and time correction prohibiting means for prohibiting the correction of the current date and time, management of the clock means by the date and time correcting means, the selecting means selects the pre-revision fee system by the date and time correction inhibiting means. It is prohibited during this period and the current date and time before the revision of the fare system is revised, so that the change from the pre-revision fare system to the post-revision fare system of the fare system applied for calculating the fare will be made before and after the actual revision date and time. It is possible to prevent the fraud and the disadvantage of passengers from occurring by eliminating the room for making the trip crazy and collecting the boarding fare at a higher amount than the original boarding fare.

Further, according to the present invention, the selecting means selects the pre-revision fee system from cumulative data including the number of times the vehicle has been operated, the cumulative amount of money calculated when calculating the boarding fare, and the number of times thereafter. And the cumulative total data holding means for updating and holding while sequentially updating and holding the cumulative data while sequentially updating and holding only while the selecting means selects the post-revision fee system. It is configured to further include cumulative data holding means and display means for displaying the boarding fare and the cumulative data before and after the revision. Therefore, the accumulated data before and after the revision is individually confirmed on the display means for displaying the fare by using the retained data in the pre-revision cumulative data holding means and the retained data in the post-revision cumulative data holding means. can do.
