【考案の詳細な説明】本考案は秤量内風袋消去機能だけでなく秤量外
風袋消去の機能をも有する電子式計重機に関す
る。[Detailed Description of the Invention] The present invention relates to an electronic weighing machine having not only an internal tare erasing function but also an external tare erasing function.

従来、風袋消去の方法としては、上述のように
秤量内風袋消去と秤量外風袋消去がある。秤量を
Ａ〔Kg〕、消去する風袋量をＢ〔Kg〕とした場合、
秤量内風袋消去は風袋消去後の有効秤量が（Ａ−
Ｂ）〔Kg〕に減少するもので、消去風袋量の大き
さに応じて有効秤量が減少するため、計重に際し
ては被計量物の重量をＣ〔Kg〕とすると、（Ｂ＋
Ｃ）＞（Ａ−Ｂ）にならないように注意しなければ
ならないという欠点がある反面、秤量Ａ〔Kg〕を
風袋用と計重用とに使用できるため、秤量が後述
の秤量外風袋消去に比べて小さくて済む。秤量外
風袋消去は風袋消去後も依然として有効秤量がＡ
〔Kg〕のものである。すなわち、秤量外風袋消去
とは、実際の秤量Aoが表示秤量〔上述の秤量Ａ〕
よりも大きいものを使用して、消去風袋量の大き
さに応じて秤量が変化しないようにしたものであ
る。しかし、この実際の秤量Aoもコストなどの
関係上、表示秤量Ａに比べてさほど大きく取れな
いため、秤量外風袋消去の場合、消去できる最大
風袋量が（Ao−Ａ）に制限される。また、前述
の秤量内風袋消去においても、秤量の数パーセン
トから数十パーセントに消去できる最大風袋量が
制限されている。このように、何れの風袋消去方
法でも最大風袋量が制限されるため、秤量内風袋
消去だけでなく秤量外風袋消去を併せて使用し
て、最大風袋量を拡大したものがある。しかし、
現在、この種の電子式計重機では、風袋の消去が
「秤量外」で消去されたのか、あるいは「秤量外」
だけで消去しきれずに「秤量内」にも喰い込んで
消去されたのかの区別が何ら表示されないため、
有効秤量が幾らであるかわかりにくいものであ
る。これを具体的な数値を挙げて説明すると次の
ようになる。 Conventionally, methods for tare erasure include intra-weighing tare erasure and off-weighing tare erasure, as described above. When the weighing weight is A [Kg] and the amount of tare to be erased is B [Kg],
The tare within the weighing area is erased if the effective weight after erasing the tare is (A-
B) [Kg], and the effective weight decreases according to the size of the erased tare amount, so when weighing, if the weight of the object to be weighed is C [Kg], then (B +
Although there is a drawback that you have to be careful not to get C) It's small enough. The effective weight is still A even after the tare is erased outside the weighing scale.
It is [Kg]. In other words, off-weighing tare deletion means that the actual weight Ao is the displayed weight [the above-mentioned weighing amount A]
A larger one is used so that the weighing weight does not change depending on the size of the erased tare amount. However, this actual weighing amount Ao cannot be much larger than the displayed weighing amount A due to cost and other reasons, and therefore, in the case of off-weighing tare erasure, the maximum amount of tare that can be erased is limited to (Ao - A). Furthermore, even in the above-mentioned intra-weighing tare erasure, the maximum amount of tare that can be erased is limited to several percent to several tens of percent of the weighing weight. In this way, the maximum tare amount is limited in any of the tare elimination methods, so some methods use not only intra-weighing tare elimination but also extra-weighing tare elimination to expand the maximum tare amount. but,
Currently, in this type of electronic weighing machine, the tare is erased "outside of weighing" or "outside of weighing".
There is no indication of whether the data was not erased completely and was erased by entering into the "weighing area".
It is difficult to understand what the effective weight is. This can be explained using specific numerical values as follows.

秤量Ａ＝５〔Kg〕、秤量外最大風袋量T_O Weighing amount A = 5 [Kg], maximum tare amount outside of weighing T _O

Claims

[Claims for Utility Model Registration] 1. The weight value at the time when tare erasure is instructed is written in the tare memory, and based on the contents, tare erasure of the weight value outside of the weighing and inside the weighing is executed from time to time. and a comparator that determines whether the content written in the tare memory is less than or greater than the maximum value of the tare amount outside of weighing, and outputs the determination result of this comparator. An electronic weighing machine equipped with an alarm means. 2. The electronic weighing machine as set forth in claim 1 of the utility model registration claim, characterized in that the alarm means is a display section consisting of an outside-weighing tare erasure display lamp and an inside-weighing tare erasure display lamp. 3. The electronic meter according to claim 1 of the utility model registration claim, characterized in that the alarm means is a sounding section that generates a specific sound when the erased tare amount exceeds the maximum value of the non-weighing tare amount. Heavy machinery. 4. Practical use characterized in that the alarm means is configured to flash the display of the weight display device that displays the weighed value after the tare has been erased when the erased tare amount exceeds the maximum value of the off-weighing tare amount. An electronic weighing machine according to claim 1 of the patent registration claim.
