摘要:
An apparatus for producing scattering signatures from a coin (105) comprises a platform (107) configured to hold the coin (105) and an electromagnetic radiation source (103) configured to produce a beam directed toward a portion of at least one surface of the coin (105). The electromagnetic radiation source (103) is arranged to produce a far-field scattering signature upon interaction the at least one surface of the coin (105). A plurality of collection elements (R3) is configured to produce an electrical signal based upon collecting at least a portion of the far- field scattering signature.

Disclosed is a method for determining the exact center of a coin that is introduced into a coin acceptor unit. According to said method, the probable center is determined by means of a sensor array, and the image of the coin that is to be examined is recorded. The peripheral area of the coin around the probable center and the zone beyond the probable edge thereof are developed using said image of the coin, the edge of the coin being represented as an approximately sinusoidal line when the probable center shifts to the exact center. The exact center is determined by analyzing the at least sinusoidal line using the amplitude and the phase angle from a selected starting point.

Bei einem Verfahren zur Begrenzung der Benutzung eines münzbetätigten Unterhaltungsautomaten einer Münz- und/oder Geldscheinverarbeitungseinheit und Eingabeelementen, die mit einer eine Speichereinheit umfassenden Steuereinheit gekoppelt sind, erfasst die Steuereinheit Ist-Werte der Münz- und/oder Geldscheinverarbeitungseinheit und/oder der Beaufschlagung der Eingabeelemente, vergleicht die Ist-Werte mit zulässigen in der Speichereinheit hinterlegten Werten und bei einer Abweichung der Ist-Daten von den gespeicherten Daten wird die Benutzung des Unterhaltungsautomaten begrenzt.
摘要:
A coin distinguishing method capable of concurrently picking up the images of the surface and the side of a coin by using two light sources, downsizing a device, and providing high-accuracy coin distinguishing. The side of a coin (C) falling through a coin passage (101) in an advancing direction is irradiated with a first light (105) from a flash shooting first light source (104), and the outer periphery portion of the surface of the coin (C) is irradiated with a second light (107) from a flash shooting second light source (106). Then, a first reflection light (108) reflected off the side of the coin (C) and a second reflection light (109) reflected off the outer peripheral portion of the coin (C) are input to an image sensor (110) to concurrently obtain the images of the side and the surface of the coin (C). A mill direction distinguishing unit (113) detects the presence/absence of mills from the picked up images of the coin (C), and a projecting pattern distinguishing unit (114) detects projecting patterns to distinguish the coin (C) based on the detection results.

A token handling device for use with a game machine in which a token (104) inputted from an input port (102) is allowed to roll along a rolling rail (106) and drop into a predetermined position of a game machine. A selecting device (112) of the token is disposed in the midst of the rolling rail (106). The selecting device (112) iriciudes at least a material sensor (150) of the token, and a cancel device (144) that removes the token rolling based on the signal from the material sensor from the rolling rail is disposed in the downstream of the material sensor.
摘要:
A method of testing an article of money comprising taking at least two measurements of an unknown article and accepting the article as corresponding to a first article type if it lies, in the space defined by the measurement axes, on a first side of a discriminant comprising a surface or line which is not parallel to one of the axes, characterised by changing the shape of the discriminant on detection of possibly non-genuine articles.
