Coin-operated machines have a long history. They were used in ancient temples to dispense holy water. The first pay phones rang a bell when you inserted a coin. And pinball machines were simple machines that had holes in the center and wires to catch things. Coin acceptors have come a long way, from these crude beginnings to the more advanced and convenient versions of today.
If you have a business where you accept coins, you may want to consider purchasing a stainless steel coin acceptor. This type of acceptor is designed to withstand the wear and tear of normal circulation. These units typically accept quarters and feature a coin acceptor switch that sends a pulse to a digital control gauge when a coin is inserted. This type of acceptor is compatible with SC05-SS (Pre-2020) and SC09-SS & SC12-SS coin machines.
Multi-coin acceptors are another type of coin acceptor. These types can handle up to six different types of coins and can even accept X-Mark(r) encoded security tokens. These units have a built-in LED for diagnostics and operation status, and they are designed to handle as many types of coins and tokens as possible.
A Fully programmable coin acceptor is a piece of equipment that can identify up to six different types of coins. These machines can be used for a variety of applications, from arcade cabinets to charging admission at a house. They are programmable and easy to use. Besides coin types, they can also detect the coins’ values and output binary bytes on a display.
Fully programmable coin acceptors are based on sensors that detect the diameter, thickness and fall time of coins. The sensors are fully programmable and the user can designate the value to be assigned to each coin. The coin acceptor will then display the value to the user on a serial output. Users can also select the baud rate on the unit.
Coin acceptors have an interesting history, going back to the days when ancient temples would use them to dispense holy water. The coin acceptor evolved quite a bit over the years, and there are now several different types available. For example, one can find a coin acceptor for a locker-sized vending machine that features an LCD display. Other uses for these coin acceptors include an arcade machine or coin kiosk.
A coin acceptor works by detecting a specific coin type. The device has built-in sensors that measure the thickness, diameter, and fall time of different coins. It is also fully programmable, and has a display that shows a variety of coin profiles. Users insert a sample coin into the coin acceptor to determine which types it recognizes and which coins it rejects.
The bill and coin acceptor consists of two housings, a first housing that houses the bill-receiving module 20 and a second housing for the coin-return module 30. These two housings are coupled with each other and fastened to the face panel. This allows the bill and coin acceptor to be a compact device.
In general, the bill-receiving module 20 consists of a bill-recognition module and a power drive mechanism. The bill-recognition module 22 is in communication with an optical recognition device. A bill-receiving module 30 includes a coin-receiving module that includes a coin sensor and an optical recognition device. The coin-receiving module 30 also has a driven gear set 34, arranged at the top and bottom sides relative to coin passage 301. A gate 35 is also included in the coin-receiving module 30.
Coupling between coils
A coin acceptor uses a transformer-like configuration composed of two coils. When a coin moves between the coils, it changes their coupling depending on its material. A coin’s diameter, for example, can determine how the coils will react to it. If the coin is recognized, a solenoid-driven flap will move out of the way to store it. If the flap doesn’t move, the coin will fall out of the coin return slot.
The coin acceptor also has a sensor that allows it to discriminate between different denominations. This feature is described in GB-A-2 169 429. The sensing station comprises coils that perform inductive tests on the major surfaces of a coin. These signals, which indicate the material content of a coin, are digitised by a microprocessor.
The sensing coil in the coin acceptor is connected to the accept solenoid L3 via a resistor. In order to detect the coin, materials that pass through the sensing coil affect the field effect transistor’s value. The resistor (R3) in the circuit is connected in series with the field effect transistor, which functions as a current-to-voltage converter. In addition to this, the accept solenoid is activated by two pairs of comparators, opto-isolators, and a triac.
A coin-sensing station consists of two coil units: a detection coil and an excitation coil. The detection coil detects eddy currents from the coins and produces a differential voltage across its windings. The detection coil is located on the same side as the excitation coil. The excitation coil is wound around an axis that is substantially perpendicular to the plane of the coins being sensed. The detection coil’s windings are concentric with the excitation coil’s windings.
A coin thickness detector is an electronic device that detects coins by detecting the thickness of the coin. This device may be calibrated for temperature or other environmental conditions. The detector transports the coin to a measurement position and aligns the coin with its sensor electrode. It then generates an output signal fVCO and a reference signal fref from VCO 13.
The coin detection system analyses the physical properties of the coin to determine its value. It can use a range of methods including infrared (IR) detection, electromagnetic detection, and mechanical detection. Depending on the coin type, detection can also be done through advanced image processing. The detection method will depend on the coin size and composition, but the basic principle is the same.
Coin acceptors use a sensor to determine the diameter, thickness, and fall time of coins. These units are fully programmable, and users can select a coin profile to insert into the machine. They also assign values to coins based on the profile that is selected. Once they have completed the process, a serial output shows the value of coins and reports it in binary values. Some units allow users to choose the baud rate that they would like to read from the unit.
A capacitive-type thickness detector is another type of coin detector. This device can detect the thickness of the coins by measuring the distance between the upper surface of the coin and the sensor electrode. Depending on the model, the device may also use other types of sensors to detect the diameter of coins.
If a coin is too large or too small for the coin acceptor, the device can reject the coin and return it to the user. In some cases, the coin can be impounded or locked so that other people cannot use it. The present invention overcomes these problems by using a mechanism that prevents oversize coins from passing through the accept outlet.
