2. Description of the Related Art Conventionally, a so-called electronic taximeter equipped with an electronic internal unit that performs various functions as a taximeter such as calculation and display of a taxi charge has been known.

FIG. 11 shows a conventional taxi meter of this kind. The front panel of the meter body 1 has a tariff switch 4 for inputting information indicating the status of the taxi vehicle, for example, empty vehicle, fare, etc. There is provided a display unit 3 for displaying a taxi fee and the like, and a name plate 5 for displaying the fee system at that time. Further, a ROM pack (not shown) in which charge information at that time is stored is housed on the back surface of the name plate 5, and the taximeter is located at a position operable from the front surface of the meter body 1. A dip switch 6 is provided for performing a distance correction work for setting and operating distance correction information specific to the vehicle to which is attached.

Here, the above-mentioned distance correction work means that when a new taxi meter is attached to a vehicle, a constant value peculiar to the vehicle, for example, a distance correction value which is the number of revolutions of the transmission per kilometer is set in the meter body 1. It is to be.

Further, inside the meter body 1, the traveling distance is measured based on a distance signal from a traveling sensor (not shown), and the traveling distance measured based on the distance correction information is corrected and corrected. Based on mileage
An electronic circuit 2 is provided for performing tasks such as updating the charge display on the display unit 3.

In such a taxi meter, when a driver carries a passenger and operates the tariff switch 4 to input information indicating a fare, the electronic circuit 2 firstly stores a fare information in the ROM pack. A basic fare, which is a fare for a basic distance of, for example, 2 km, is read out and displayed on the display unit 3, and then the traveling distance of the vehicle is measured based on the distance signal. Then, when the traveling distance reaches the basic distance, the subsequent charge, which is a boarding charge for a subsequent distance of, for example, 500 m, is read from the ROM pack and is changed to a charge added to the charge currently displayed on the display unit 3 It is supposed to update. It should be noted that the update of the charge display takes into account not only the travel distance but also the travel time.

Further, since the taximeter is a measuring instrument, a seal is attached to its mounting portion so that the taximeter cannot be removed from the vehicle, and the nameplate 5 is mounted so as not to be easily tampered with. The parts are also sealed so that the ROM pack housed on the back side cannot be easily replaced.

In such a taxi meter, when it is necessary to replace the taxi meter due to price revision or the like, the taxi meter is removed from the vehicle and collected, and a ROM pack storing new charge information and a new charge system are displayed. The nameplate 5 and the nameplate 5 are exchanged at a factory or the like and then attached to the vehicle. When the modified meter is attached to the vehicle, the distance correction work is performed by the dip switch 6.

Since the taximeter removed from the vehicle is not always attached to the original vehicle, it is essential to correct the distance when the modified meter is attached to the vehicle.

[0010]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional taximeter, a large number of taximeters are collected from the market at one time at every price revision, etc., and remodeling work is carried out in a factory or the like. Is attached to each vehicle, and since such work must be performed in an extremely short time, the distance correction work for each vehicle when installing the above-mentioned modified meter becomes extremely complicated, and in some cases There was an inconvenience such as forgetting the correction work.

The present invention has been made in view of the above-mentioned points, and it is possible to save the labor of remodeling work when exchanging a taximeter at the time of revision of a charge, and to perform a reliable work in a short time. It is intended to provide.

In order to achieve the above object, a taximeter according to the present invention is mounted on a mounting plate which is fixed to a vehicle side and receives various traveling signals based on a distance signal in the traveling signals. In addition to measuring the mileage, correcting the measured mileage based on the distance correction information, attaching a meter body that displays the fare based on the corrected mileage, and sealing the taxi meter, the mounting plate In addition, a storage means for storing the distance correction information is provided.

The storage means is a mechanical storage means for mechanically holding distance correction information.

Further, the storage means is an electrically writable storage means, and the meter body is provided with a writing means for writing the distance correction information in the storage means.

[0015]

According to the present invention, the storage means for storing the distance correction information is provided on the mounting plate to which the meter body fixed to the vehicle is mounted. Therefore, when a new taxi meter is mounted on the vehicle, If the distance correction information, which is a unique constant, is stored only once in the storage means of the mounting plate, it is not necessary to perform the distance correction work each time the meter body is detached or attached, and the charge revision is omitted by omitting the correction work. It is possible to save labor for remodeling work when removing the taxi meter.

[0016]

In this case, since the mounting plate 11 is not removed from the vehicle as described above, the distance correction work by the dip switch 6 of the mounting plate 11 which is already performed when a new meter is mounted is required to be corrected at this rate. You don't have to do it.

Therefore, in the present embodiment, each time the charge is revised, only the meter body 1 modified according to the new charge needs to be attached to and detached from the mounting plate 11 fixed to the vehicle. The distance correction work performed on the side need only be performed once when the mounting plate 11 is newly fixed to the vehicle when the mounting plate 11 is fixed to the vehicle, and it is not necessary to perform it every time the meter body 1 is attached or detached thereafter. By omitting such distance correction work, it is possible to save labor in remodeling work at the time of price revision, and also to prevent forgetting the correction work that occurs because distance correction work is performed each time remodeling work is done as in the past. As a result, reliable remodeling work can be performed in an extremely short period of time.

FIGS. 4 to 8 show a second embodiment of the taximeter according to the present invention. In the case of this embodiment, the mounting plate is provided so as to project from the lower edge of the front panel of the meter body 1. A changeover switch 19 for changing over the function of the meter main body 1 is formed on a portion of the sealing bolt 9 for performing the traveling sealing 18 in cooperation with the sealing bolt 7 of 11. In addition, the distance correction information, which is electrically writable and stored without a backup power source, is stored in the storage portion 11a of the mounting plate 11 fixed to the vehicle side that can be brought into contact with and separated from the back surface of the meter body 1. Non-volatile memory that can be used 2

The electronic component 1 is the meter body 1 via the connector 13
It is designed to be connected to the CPU 21.

Next, a modification work when the above-mentioned taximeter needs to be replaced will be described. First, as a precondition for remodeling work, when a meter is newly installed in a vehicle, it is necessary to perform distance correction work according to the vehicle. The procedure will be described below with reference to FIG.

The ROM main body 22 storing predetermined charge information and the nameplate 5 displaying the charge system are attached to the meter body 1 with the head seal 16 attached to the attachment plate 11 fixed to the vehicle side. Then, when the changeover switch 19 is turned on (step S1), the function of the meter body 1 is switched from the original charge calculation function to the distance correction information input function for writing predetermined distance correction information, and the memory 2
The content of 0 is read, and a predetermined numerical value (if the predetermined distance correction information is already stored, that numerical value) is displayed on the display unit 3 (step S2). If the changeover switch 19 is not turned on here, the CP of the meter body 1
The U21 calculates the charge, which is the original function, and displays the charge and the like on the display unit 3 (step S3).

When the empty wheel button 4a as the tariff switch 4 arranged on the right side of the upper edge of the front panel of the meter body 1 is turned on with the distance correction information input function switched (step S4), the initial value of n is 0. Therefore, the value of n becomes 1 (step S5), and the numerical value of the least significant first digit of the display on the display unit 3 starts blinking (step S5).
6). In step S4, the empty button 4
When a is not turned on, it waits until the empty button 4a is turned on.

When the cumulative value button 4b on the left side of the front upper edge of the meter body 1 is turned on while the first digit of the display section 3 is blinking (step S7), the digit of the blinking digit is 1 Will be added (step S
8) The display of the digit is updated. In addition, in step S7, when the cumulative button 4b is not turned on,
It is determined whether or not the empty vehicle button 4a is turned on (step S9). When the empty vehicle button 4a is not turned on, the process returns to step S7 again, and waits until the cumulative button 4b is turned on. Further, in step S9, when the empty button 4a is turned on, the process returns to step S5, the value of n becomes 2, and the lower second digit of the display unit 3 blinks.

If the initial value displayed on the display unit 3 is, for example, 4 digits, it is determined whether or not the digit of the numerical value which is currently blinking is the 4th digit of the highest digit (step S1).
0) If it is determined that it is not the highest digit, it is determined again whether or not the empty button 4a is turned on (step S1).
1) Further, it is determined whether or not the cumulative total button 4b is turned on (step S12). When the cumulative button 4b is turned on in step S12, the process returns to step S8 in order to add 1 to the blinking numerical value.

When the empty button 4a is turned on in step S11, the process returns to step S5, the value of n becomes 2, and the lower 2nd digit starts blinking.
The operations of steps S7 to S12 described above are performed again,
The display of the second lower digit is updated.

In this way, when it is determined that the display of all the digits of the initial value of, for example, four digits displayed on the display unit 3 has been updated (step S10), the blinking of the display of the fourth digit ends. Then, the numerical value of the newly input distance correction information is displayed on the display unit 3 (step S13). In this state, it is judged whether or not the changeover switch 19 is ON (step S14), and when the changeover switch 19 is turned off, new distance correction information is stored in the memory 20 (step S15), and the meter is attached. The distance correction work will be completed.

When the distance correction work is completed, as shown in FIG. 8, the changeover switch 19 portion is covered with the blind plate 26, and the mounting plate 1 protruding from the front surface of the meter body 1 is attached.
The running seal 18 is provided through the seal line 17 between the seal bolt 7 of No. 1 and the seal bolt 9 provided on the blind plate 26.

In such a state, when the fare is revised, the running seal 18 is cut and only the meter body 1 is removed from each vehicle and collected as in the first embodiment.
The ROM pack 22 storing the new charge information and the nameplate 5 displaying the new charge system are collectively replaced at a factory or the like. After the head seal 16 is made on the factory side, the modified meter body 1 is attached to the mounting plate 11 of each vehicle, and the running seal 1
It is supposed to do 8. In this case, as described above, since the distance correction information peculiar to the vehicle has already been input and stored in the memory 20 in the mounting plate 11 that is not removed from the vehicle, the distance correction is performed each time the charge is revised. Eliminates the need to do work.

Therefore, also in the present embodiment, the distance correction work need not be performed each time the meter body 1 is attached or detached thereafter, if it is performed only once when a new meter is attached to the vehicle. By omitting the correction work, it is possible to save labor for the remodeling work when the charge is revised.

6 and 8 to 10 show a third embodiment of the taximeter according to the present invention. In this embodiment, the sealing bolt 7 at the lower edge of the front panel of the meter body 1 is used. On the side of the insertion hole 8 through which is inserted, there is formed a setting portion 29 in which a dip switch 27 and a transfer switch 28 for performing a predetermined distance correction work are arranged, and a front opening portion of the setting portion 29 is formed. Is covered with a blind plate 26 provided with a sealing bolt 9 which cooperates with the sealing bolt 7. In the internal circuit configuration of the meter main body 1, the dip switch 27 and the transfer switch 28 are connected to the CPU 21 instead of the changeover switch 19 of the second embodiment shown in FIG. It has the same configuration as that of the embodiment.

In such a taxi meter, the procedure of the distance correction work to be performed when the meter is newly installed in the vehicle is as follows.
First, with the meter body 1 attached to the mounting plate 11, the dip switch 27 is operated to set the distance correction information to be input. In this state, as shown in FIG. 10, when the transfer switch 28 is turned on (step S
1), the set value of the DIP switch 27 is transferred and read into the memory 20 in the mounting plate 11 (step S2). Here, if the transfer switch 28 is not turned on, the CPU 21 of the meter main body 1 performs a charge calculation and the like to display the charge and other indications on the display unit 3 (step S3). Then, when the reading into the memory 20 is completed and the transfer switch 28 is turned off (step S
4) The CPU 21 is adapted to display charges and other displays as the original function on the display unit 3. In addition,
In step S4, the transfer switch 28 is turned off.
If not, it waits until it is turned off.

When the distance correction work is completed, the setting unit 29 is set as in the second embodiment shown in FIG.
Is covered with a blind plate 26 so that the running seal 18 is provided.

Therefore, when there is a price revision, the above first
Also, similarly to the second embodiment, only the meter body 1 needs to be modified, and the memory 20 in the mounting plate 11 fixed to the vehicle side.
Since the predetermined distance correction information has already been stored in,
When the modified meter body 1 is attached, it is not necessary to perform the distance correction work, and the modification work at the time of price revision can be saved.

The present invention is not limited to the above embodiments, but can be modified in various ways.
For example, only in the first embodiment, the running seal 18 may be performed only by the seal bolt 7 of the mounting plate 11 protruding from the front surface of the meter.

As described above, in the taximeter according to the present invention, the mounting plate to which the meter main body fixed to the vehicle is mounted is provided with the storage means for storing the distance correction information. When the taximeter is mounted, if the distance correction information, which is a constant peculiar to the vehicle, is stored only once in the storage means of the mounting plate, it is not necessary to perform the distance correction work each time the meter body is detached or attached thereafter. By omitting such correction work, it is possible to save labor for remodeling work when removing the taxi meter at the time of rate revision, and also for the correction work that occurs because distance correction work is performed every time remodeling work is done as in the past. It is possible to prevent forgetting, and it is possible to perform a reliable modification work in an extremely short period of time.
