【考案の詳細な説明】 本考案は被計量物の計量値と予め設定された単価との積
によって前記被計量物の価格を演算してこれをデジタル
表示する電子式料金はかりに関する。
[Detailed Description of the Invention] The present invention relates to an electronic price scale that calculates the price of the object to be weighed by multiplying the measured value of the object by a preset unit price and digitally displays the price.

従来、計量値は一般使用状態において、完全に一点で静
止し難く、周囲の条件により被計量物の重量値近傍で振
動するものである。
Conventionally, in general use, the measured value is difficult to remain completely stationary at one point, and oscillates around the weight value of the object to be measured depending on the surrounding conditions.

その為前記料金はかりの表示する被計量物の価格は一つ
の価格を固定的に表示し難く、計量値の変化に伴って変
動するものであった。
Therefore, the price of the object to be weighed displayed by the price scale is difficult to display in a fixed manner, and changes as the measured value changes.

そこで客との金銭的トラブルを避けるためにタイマ回路
をもった記憶回路を設け、計量値が安定状態に達したも
のと操作者が判断すると、前記タイマ回路を動作させ、
その時刻の金額値を一定時間保持して表示させるもので
あった。
Therefore, in order to avoid financial troubles with customers, a memory circuit with a timer circuit is provided, and when the operator determines that the measured value has reached a stable state, the timer circuit is activated.
The monetary value at that time was held and displayed for a certain period of time.

しかし、該記憶された金額値はタイマ設定時間内であれ
ば、表示されている金額値が不必要となったにも係わら
ず金額値は前記設定時間まで継続して表示されるもので
あり、また一方計量が完了しておらず表示されている金

達すると、前記記憶は解除されてしまうものであった。
However, as long as the stored monetary value is within the timer setting time, the monetary value will continue to be displayed until the set time, even though the displayed monetary value is no longer necessary. On the other hand, even though the metering has not been completed and the displayed monetary value is still needed, when the timer setting time is reached, the above-mentioned storage is canceled.

従って操作性が悪く、操作者が計量値の安定状態を判別
するため正確なものではなかった。
Therefore, the operability was poor, and it was not accurate because the operator had to judge whether the measured value was in a stable state.

そこで本考案は上記欠点を解消し、正確で且つ確実な電
子式料金はかりを提供するものである。
