A Coin acceptor is an electronic device that enables you to detect coins by sending pulses to the receiver. There are different pulses for different coins. For example, a 50 cent piece sends two pulses while a dollar coin sends four pulses. A quarter, on the other hand, sends one pulse. So, a quarter is worth one credit in a game. However, a half dollar will send four pulses while a quarter is worth one credit in a game.
Guide plate 32
The electronic coin acceptor comprises a main frame plate and two side plates, which extend perpendicularly from the main frame plate. The opening lever, which is pivotally attached to one of the plates, produces a gate actuating signal. The casing, which is made of plastic, is also integral. A slot or recess in the front of the acceptor is provided for the coin lip. The coin acceptor is made of several parts, which are described below.
The guide plate 41 and jam plate 44 are connected to each other through two pins. When a coin 5 drops into the slot 42, it hits the inclined surface 442 and drops into the distinguishing device 2. The second torsion spring 43 is mounted to the other pin. The coin slot 42 and jam plate are positioned at the distal ends of the coin acceptor. They are connected to each other via a spring hinge 45.
The coin passage wires are pushed by the spring to the opening 8c. The connector 12 receives information signals about the coin. The plate 13 has a slot 16.
The outer plate assembly includes an outer plate 30. The cover plate holds the sensor assembly. Inner and outer coin guides 90 and 92 can be adjusted to different heights. The cover is locked in place by screws. The plate also contains a visual position indicator feature, which reflects the coins guides in the slots. This indicator feature consists of position holes and a slot, and a hole in which to view their position.
The coin reject bar can be programmed to reject all coins or a few types. The machine recognizes a particular coin type based on its diameter, thickness, and metal content. The user can adjust the sensitivity of the sensors. The machine also has switches for normal open and close, VR tuning, and Counter Meter connections. Ultimately, the coin acceptor can monetize your next project. There is no better time than the present to begin making your next project.
At least one sensor
A coin acceptor is a device that detects coins. This machine typically has a number of sensors on its front end, and at least one of these sensors is responsible for detecting coins. The sensors are usually located near the coin acceptor’s ejector drum, so that they can easily be spotted. The sensors are used in combination with a coin detection circuitry that is part of the machine.
The sensors measure the signature signals from a variety of frequencies. Moreover, the output signals can be analyzed to determine the alloy content of a coin. The present invention is particularly useful when trying to discriminate between coins of similar alloy contents and sizes, as many of the coins sold in the European market come from different countries. A sensor that can detect these differences is useful in determining the origin of coins and avoiding counterfeits.
Another useful sensor for a coin acceptor is a lag sensor. Lag sensors are used downstream of the air valves for coin ejection, so that they can confirm that the coin has been ejected correctly. In addition, separate calibration values are acquired for each location of the counterbore, which helps offset the effects of differences in the circuitry or slight mechanical irregularities. Moreover, the sensors can be easily programmable so that they can be programmed to be used with the appropriate coin denomination.
The Oscillating Circuit for Coin Acceptor is a device for accepting and rejecting coins. It consists of a sensing coil and an oscillator circuit. The coils are placed substantially parallel to the coin path. The coin passes through the field when it is placed within the sensing coil. The device detects the presence of coins and then moves the flapper out of the slot.
The Oscillating Circuit for Coin Acceptor includes two transistors with interconnected emitters. One transistor serves as a base decoupling capacitor and the other as an output coupling capacitor. The transistors’ collectors are connected to an AC ground. The combined resistance of the two components is 10KO. A current source (C1) provides the voltage across the transistors. The resulting voltage controls the solenoid.
A valid coin has a diameter between 20 and 60 mm and a depth of between 1.5 and 2.5 mm. The coin must pass through a predetermined path to be accepted. The Oscillating Circuit for Coin Acceptor has a programmable frequency, which allows it to automatically detect and reject specific types of coins. The Oscillating Circuit is a highly flexible and programmable device, and the Oscillating Circuit provides a stable and dependable signal.
The Oscillating Circuit for Coin Acceptor begins with a voltage comparator. The voltage of this circuit changes with the presence of a coin. If the coin is present, the voltage of comparator 41 changes state. Otherwise, the coin does not enter the circuit. Once the coin is present, the circuit switches to case (d).
The circuit for a Coin Acceptor may include one or more spiral coils. The coils are connected along the coin’s travel path. The coils receive a voltage from the coin and adjust their amplitude. The coils also contain a capacitor. The second circuit means detects a particular amplitude detection band. When the coin is placed, the coil changes its resonance frequency. This means that the coin will be detected if the coils are in the correct position.
Gate actuating signal
A coin acceptor is a component of a vending machine. The coin acceptor receives coins and checks the validity of each coin before accepting it for use in the vending machine. The coin acceptor is a low-cost device, and is not very complicated to install. It validates each coin by analyzing its metallic content and material. The value of the input signal is compared to the value of the transaction to ensure that it is valid and can be used for payment.
A comparator circuit includes a first branch and a means for sensing a first parameter, such as the voltage. The second branch, which is coupled across an active element (FET1) and separated from the first branch, detects a change in frequency in an oscillator circuit. When the first and second parameters coincide, the solenoid (L3) is energized. If the first and second parameters coincide, the coin acceptor will be actuated.
The present invention provides an apparatus for accepting and rejecting a single type of coin. It is designed to accept genuine coins of a particular value and reject spurious coins and slugs. It further provides an auxiliary coin acceptor-rejector component that can be readily fitted to an existing coin-operated device. The auxiliary coin acceptor-rejector component can discriminate between genuine and spurious coins.
While Mars’ 903 Patent does not contain a structure for a “means to inhibit” the gate actuating signal, it does include an accumulator that signals that the accumulator has received sufficient money for a transaction to continue. Whether the user actuates the product selection switch, he or she will be unaware of the “means to inhibit” feature. This enables the vender to continue operating until the user activates the product selection switch.
