2. Description of the Related Art Conventionally, the amount of electricity, gas, water, etc. used is measured by an integrating meter, and the output display value is metered at regular intervals. By the way, the output display value of the meter is represented by a numerical value or a symbol as a digital scale.The meter reader reads the numerical value or symbol and writes it in a notebook, or the key input (data It is common to enter).

On the other hand, there is one in which a bar code is individually attached to identify the meter from which the numerical value / symbol is read, and the bar code is attached around the meter. When the meter is identified by the bar code as described above, the meter reader reads the numerical value / symbol, and the bar code is stored in the meter using the reader.

[0004]

However, in such a conventional method of reading the output display value of a meter, since the numerical value of the meter and the identification of each meter are separately performed, when the values are aggregated later, each There is a problem that the numerical value of the meter does not always match the bar code, and the numerical value of another meter may be input as the value of the corresponding meter.

In view of such conventional problems, the present invention displays the meter output display value and the identification symbol of each meter on the same screen and reads them by the same reader to read the meter. It is an object of the present invention to provide a method for reading the output value of a meter that can reliably prevent the error of

[0006]

In order to achieve the above object, the present invention provides an identification symbol to each meter of electricity, gas, water, etc., and the identification symbol and the output display value of the meter are
A method of displaying on the same screen using a liquid crystal display or a light emitting diode, and reading both the identification symbol and the output display value from this display screen using the same reader.

Further, in such a method, it is desirable to simultaneously display the identification symbol and the output display value on the display screen.

Further, it is possible to switch the identification symbol and the output display value respectively and display them separately on the display screen.

Furthermore, it is desirable to display the identification symbol as a bar code.

[0010]

According to the method for reading the output value of the meter of the present invention having the above construction, the identification mark of each meter and the output value of the meter displayed on the same screen are read using the same reader. Therefore, the identification symbol of each of these meters and the output display value can be input to the reader as a unit. Therefore, it is possible to surely prevent the mistaken identification of the meter with respect to the output display value of the specific meter, and simply press the reader against the screen to display the identification symbol and the output display value. Since it can be read, the meter reading work of the meter can be greatly simplified.

By simultaneously displaying the identification symbol and the output display value on the display screen in such a method, the input work by the reader can be performed only once.

Further, by switching between the identification symbol and the output display value and separately displaying them on the display screen, the identification symbol and the output display value can be displayed on the full screen, and the display screen can be made compact. Can be achieved.

Furthermore, by displaying the identification symbol as a bar code, a huge number of meters can be accurately identified with a small screen.
