A coin entering from a depositing port of a coin selector is identified by a denomination while passing through a coin passage. A coin of a predetermined denomination is stored, and a coin of a denomination other than the predetermined denomination is discharged to the outside. Provided is a coin selector including a removal mechanism that suitably removes a coin clogged in a coin passage. The coin selector includes a first pushing portion and a second pushing portion that push a coin in a moving direction of the coin and a direction intersecting with the moving direction in the coin passage from a depositing port for depositing the coin to a dispensing port for discharging the coin. When the coin is clogged, the coin is pushed by a pushing unit to eliminate the coin clogging, and the clogged coin is discharged to the dispensing port.

A coin dispenser is disclosed to use a dialing rod of a dialing device of a coin dispensing unit to push one side of the peripheral edge of one metal coin so that the other side of the peripheral edge of the metal coin will push two coin-stopping columns of one spring plate of the coin dispensing unit, causing the two coin-stopping columns to slide along the peripheral edge of the metal coin, and thus, when the metal coin crosses two coin-stopping columns, the metal coin is sent out of the coin outlet, achieving the effect of dispensing one metal coin at one time.

An electronically actuated coin slider provides an appearance and operation similar to a conventional coin-activated slider without the use of coins. A card reader activates the coin slider and allows a user to push the slide bar to actuate a game, machine, or device in a manner similar to that of a convention slider. A servo motor engages or disengages latching hooks to prevent or allow operation of the slide bar.

A coin detection antenna includes a substrate and a plurality of air core coils of track shape including a wiring pattern provided on the substrate. The plurality of air core coils is disposed along short-side directions of air cores of the plurality of air core coils such that a smallest coin of coins to be detected crosses at least one of centerlines of the air cores even when the smallest coin is located at any location in a detection range.

Systems, apparatus, and methods for tracking or monitoring utilization of a coin-operated device without opening the device. The device can be designed, retrofitted, to have an electronic counting system, generally including a small circuit board with a controller, counter, and transceiver. The counting system is also connected to the coin-operated apparatus to detect use, such as by detecting the passage of a coin. The counter is then incremented. The current count can be queried by a mobile device or other computer via the wireless transceiver, and other instructions can be sent, such as to reset the count to zero.

A coin placement unit is equipped with: a coin spread portion having two perpendicular wall surfaces and a recessed surface comprising a gutter-shaped recessed portion extending in the direction orthogonal to the perpendicular wall surfaces between the two perpendicular wall surfaces; a coin slot portion having a coin slot; and a ridge line portion provided between the coin spread portion and the coin slot portion so as to partition the coin spread portion and the coin slot portion. The coin spread portion, the ridge line portion, and the coin slot portion have the same width and are continuous in the direction toward a depth side.
