紙幣収容部（８１）を有する引き出し（７０）と、キャッシュドロワ本体（２０）とを備えている。キャッシュドロワ本体（２０）は、引き出し収容部（２１）と、正面開口部（２２）と、引き出し収容部（２１）の天面を画定する天面部（４１）を含む天面部材（４０）と、正面開口部（２２）の縁部を画定する正面枠部（５１）を含む正面部材（５０）とを有している。引き出し収容部（２１）の天面に直交する方向から見た場合に、引き出し収容部（２１）の天面のうち引き出し（７０）を出し入れする際に紙幣収容部（８１）が通る領域において、引き出し収容部（２１）の天面に平行で第１方向（Ｘ）に交差する方向に延びる継ぎ目を正面部材（５０）と天面部材（４０）との間に形成することなく、正面部材（５０）と天面部材（４０）とが連結されている。

An intelligent cash drawer unit or cash register is operable to process signals from load cells beneath note/coin cups when the drawer is open. It then determines the weight/value of cash in the cups, in order to either (a) detect an accurate weight in a cup comprising a poorly placed note, or (b) allow a float to be added, or a lift to be made, stepwise, whilst the drawer remains open. An intelligent cash drawer unit or cash register is also described which can detect a poorly placed note, by either (a) comparing signals from the load cells when the drawer is open, and when the drawer is closed or (b) monitoring stable readings, over a predetermined period when the drawer is closed and comparing the monitored values and where the apparent weight determined by the transducer appears to reduce by more than a predetermined amount, determining that a note is poorly placed.
