ている。2. Description of the Related Art In order to eliminate erroneous reading and erroneous recording when reading a numerical display device of an integrating meter such as a measuring instrument, an integrating meter in which a bar code code is attached to a numerical display portion to enable machine reading is used. It is disclosed in JP-A-7-13097.
【０００３】この従来技術では数値表示部（数字車又は
表示車とも言う）のバーコード表示部分を非接続、非接
触で数値を機械的に読み取ることで迅速且つ正確な記録
ができる。In this prior art, a bar code display portion of a numerical value display unit (also referred to as a numeral wheel or a display wheel) is disconnected and non-contact mechanical reading of a numerical value enables quick and accurate recording.

最上位桁の数字車（表示車）に所定のバーコードの他に
その左端にスタートコードを付すとともに、最下位桁の
数字車に所定のバーコードの他にその右端にストップコ
ードを付して、それぞれ専用の数字車を製作していた。
そのため、管理が煩雑で高価になるという問題点があっ
た。In the above prior art,
In addition to the predetermined barcode, a start code is added to the left end of the most significant digit car (display car), and a stop code is attached to the right end of the least significant digit car in addition to the predetermined barcode. , Each had its own numeric car.
Therefore, there is a problem that management is complicated and expensive.
【０００５】また、各数字車には、数字とバーコードと
を円周方向に離して独立した位置に並記する方法をとる
ため、それ以前の目視に用いる数字だけを表記したもの
に比較して、数字車の直径を同じにすると数字の大きさ
が半分程度に小さくなって数字を目視で読み取りにくい
という問題点があった。[0005] In addition, in order to adopt a method in which each numeral wheel has a numeral and a barcode which are separated from each other in a circumferential direction and are arranged at independent positions, a comparison is made between the numeral wheel and the numeral used only for visual observation. Therefore, when the diameter of the numeral wheel is made the same, the size of the numeral is reduced to about half and there is a problem that the numeral is difficult to read visually.
【０００６】また、水道メータのような直読式の数字車

いると、バーコードに不連続なブランク（空白）が生
じ、機械的に読み取るときに誤読を招き易いという問題
点があった。Further, in a direct-reading type numeral wheel such as a water meter, there is a gap between adjacent numeral wheels for fitting a transmission pinion. Therefore, a bar code system disclosed in Japanese Utility Model Laid-Open No. 7-13097 is disclosed. When used in such a water meter, there is a problem that a discontinuous blank (blank) is generated in a barcode, and erroneous reading is likely to occur when reading mechanically.
【０００７】更にまた、バーコードはその並び方向に走

とする。Furthermore, a bar code is not scanned in the direction in which it is arranged, and a reading error occurs. Therefore, there is a problem that the operation of the reader cannot be easily handled by anyone. Therefore, an object of the present invention is to provide a water meter display device and a reading method thereof that can solve these problems.
