Description

  The present invention relates to a coin deposit / withdrawal apparatus used by being connected to an electronic device such as a POS (Point Of Sales) terminal or an ECR (Electronic Cash Registrar).

  Some coin deposit / withdrawal devices employ a method in which coins inserted into a coin slot are sorted and dropped according to denomination by a coin sorting hole and stored in denomination in a coin storage unit (for example, Patent Documents). 1). When a coin that has been deformed, a scratched coin, or a coin with a foreign object is inserted into such a coin depositing / dispensing device, a so-called coin jam may occur in which the coins stay inside the device. . As a technique for eliminating the coin jam, Patent Document 1 proposes to repeatedly reversely drive the payout belt in both forward and reverse directions. However, as described in Patent Document 1, if the coin stagnation is not eliminated by the above-described method, an error notification is made to notify that the coin stagnation has occurred, such as sounding an error sound, It is necessary to take measures such as removing the coins that have accumulated by hand.

  In the coin deposit / withdrawal apparatus as shown in Patent Document 1, when the cashier recognizes that a coin jam has occurred in the apparatus by an error notification, the coin that has been pulled out of the main unit of the apparatus and stays inside the apparatus Will be removed. At this time, the staying coins may be in a state where they are likely to fall into the coin sorting hole in the vicinity of the coin sorting hole. In this case, the staying coins may fall into the coin drop hole due to the vibration of the apparatus when the main unit is pulled out. When you pull out the main unit, it is necessary to put the equipment in a stopped state. If a coin falls into the coin drop hole, the dropped coin is stored as the number of coins stored in the coin storage unit. This is not counted and causes an error (counting error) between the stock information stored in the memory of the device and the actual number of coins in the coin storage unit. Also, if the coins that are staying fall due to vibration when pulling out the main unit, the coin will be stored in the coin storage part where the coin of a denomination different from the denomination of the coin is stored, This may cause a miscalculation.

The coin deposit device of the present embodiment includes a coin slot, a transport mechanism that transports coins inserted into the coin slot, a denomination determining unit that determines the denomination of coins transported by the transport mechanism, A hole in which the coin whose type has been determined by the denomination determining unit falls into a denomination, a detection unit that detects a coin falling from the hole as a denomination, and a coin detected by the detection unit as gold A coin storage portion that is stored in a type, a first position that allows the coin to reach the coin storage portion from the hole portion, and a second that prevents the coin from reaching the coin storage portion from the hole portion. The receiving member that is displaced between the position and the denomination determining unit determines the denomination of the coin, and when the detection unit does not detect the coin of the denomination within a predetermined time, Control means for positioning from the first position to the second position .
