Abstract: A merchandise sales data processing apparatus includes a display device and a first display control unit. The first display control unit displays balance information and an input area simultaneously on the display device. The balance information is information regarding balance of each denomination in an automatic change dispenser which deposits or dispenses money. The balance information is generated by a balance information generating unit. The input area receives, through an input device, the input of change reserves information regarding change reserves that should be prepared in the automatic change dispenser.

Abstract: The invention provides a method of determining completion of coin insertion capable of easily and reliably determining whether or not a number of coins required for purchasing an article has been inserted. A coin holding portion (105) is constructed such that coins are retained in row in the coin holding portion (105) being electrically connected to each other in series. Further, a first electrode (121) that comes into contact with the coin located at one end side of the row is provided in the coin holding portion (105); and a second electrode (123) that comes into contact with the coin located at the other end side of the row is provided in the coin holding portion (105). The coin holding portion (105) is constructed to detect an electric current between the first electrode (121) and the second electrode (123) to determine whether or not the required number of coins has been inserted.

Abstract: An electronic coin counter for use with cash register drawers. Coins are poured from the cash register drawer through openings in the top of a housing into sleeves that correspond to the denomination of the coins. Internal sensor tips are then brought into contact with the resulting column of coins by forcing a bar outside the housing in toward the housing. This activates a switch to supply electrical power to internal electronics and to external digital displays. The sensor tips are oriented in staggered pairs to prevent counting errors due to the presence of worn thin coins. Mathematical addition and multiplication necessary to obtain the monetary value of each denomination of coin and the total value of all the coins is performed automatically by internal logic circuitry. The monetary totals are then sent to the external digital displays while the coins are automatically ejected through holes in the bottom of the housing underneath each sleeve.

Abstract: A coin box monitoring circuit for use in pay telephones, providing coin detection, coin volume totalization, and full coin box signaling to the telephone central office. An included coin chute assembly has three channels that cause nickels, dimes, and quarters to pass through specific locations within each channel. Light sources and light detectors detect the passage of coins. A microprocessor is utilized to control the light sources, monitor the detectors, and volumetrically count the coins passing through the coin chute. On reaching a full condition, a microprocessor then controls a relay to signal that the predetermined coin box level has been reached.

Abstract: A coin validating apparatus having a coin carriage for moving the coin along at least one coin track. The coin carriage has at least an electrically conductive portion in contact with the coin. The coin track has at least one cam at a predetermined location, the cam having at least a substantially non-conductive base portion attached to the coin track and an electrically conductive top portion. A component for detecting current is connected in series with the top portion in a first terminal of a voltage souorce. A second terminal of the voltage source is connected to the electrically conductive portion of the coin carriage. The coin completes an electrical connection between the electrically conductive portion of the coin carriage and the top portion of the cam when the coin carriage has positioned the coin over the cam and when the coin is electrically conductive. When the coin comnpletes the electrical connection, the component for detecting provides a signal indicative thereof.
