APPARATUS FOR DECTING THE AMOUNT OF COIN-CHARGING AND DECTING SYSTEM OF FILING A COIN HAVING THE SAME

摘要

PURPOSE: A supplement coin amount detecting apparatus, a coin charging system including the same, and a method for detecting supplement coin amounts are provided to accurately detect the number of coin supplement amounts of a coin feeder by measuring the number of coins which are actually used. CONSTITUTION: A coin feeder is attached and detached inside a housing(110). An elevating unit(120) is combined with the housing which can be slid. The elevating unit ascends and descends from a start point to a finish point. One end of a measuring bar(130) is loaded on the elevating unit and connected to the elevating unit at the start point. The measuring bar is touched with the uppermost coin of the coin feeder and stops the falling with the elevating unit at the same time or stops the falling earlier than the elevating unit. A falling distance detection unit(140) measures falling distance of the measuring bar. A supplement coin output unit(150) calculates the number of coin supplement amounts based on correlation of the falling distance and the number of coins which are actually used.
