  • Patent number: 8747194
    Abstract: A device for singularising coins of different sizes and thickness with a housing which comprises an obliquely inclined base plate is suggested. A catch element for catching and conveying coins to a further processing is rotatably arranged above the base plate. The coins are randomly present at least in the lower region of the base plate on which a collection container is fastened.

  • Publication number: 20100136894
    Abstract: A coin storage device, which can be inserted in a coin testing device or in a cash register system, is described. The coin storage device comprises at least two opposing walls, wherein between the walls a shaft having a width is configured, and a track disposed in the shaft is provided. Of the two opposing walls, at least one is at least partially displaceable, and the width of the shaft can thus be varied. The track is arranged displaceably, and at least one retaining rail is provided, wherein the retaining rail is displaceably disposed above the track in the shaft. Such a coin storage device can be used to sort out foreign objects based on gravity. A coin storage device is possible for a coin testing device, and congestion by coins or foreign objects can be eliminated due to the variable width of the shaft.

  • Patent number: 7614544
    Abstract: An intermediate cash box includes a flap assembly that is pivotally mounted in a housing, said assembly forming a receptacle for coins in its resting position. When the flap assembly is pivoted in a controlled manner, this releases the coins into a return channel or a cash box. The flap assembly comprises two V-shaped flaps, each flap being assigned to a pivotally mounted gate lever with a slide-gate track that guides the displacement of the flap. A rotatably mounted displacement transfer element, which is driven by a drive, is in contact with the gate levers and transfers the displacement of the drive to one of the respective gate levers in order to pivot the latter.

  • Publication number: 20090205928
    Abstract: An electronic coin checker is disclosed, comprising a coin insert, a coin running track, in the region of which at least one checking device, for checking the coins, is arranged and a deflector. According to the result from the checking device, the deflector may be placed in a withdrawn position, opening the acceptance channel, or in an extended position, in which the coin is deflected into a return channel which ends in a return opening in the front region of the coin checker. The deflector comprises means for clamping which clamp a false coin introduced through the return opening in the extended state of the deflector, by means of withdrawing the deflector.

  • Patent number: 7552811
    Abstract: Disclosed is a method and device for testing coins which are placed in a coin acceptor unit and which are displaced in front of an image sensor consisting of lines and columns, whereby said image sensor records an image of the coins that are to be tested. At least one of the front columns in the direction of movement of said coins and/or at least one line of the image sensor captures parameters, which in conjunction with the temporal detection information, are used to provide information on the movement of said coins. It is determined independently from said parameters when the coin will appear in a desired overlap area for recording, whereby the image sensor is shifted into an activation mode of the columns and lines of the overlap area and recording is triggered.

  • Publication number: 20080128243
    Abstract: A method for determining an exact centre of a coin introduced into a coin acceptor unit, the method comprising: determining a probable centre of the coin by means of a sensor arrangement; recording an image of the coin to be examined; and developing an edge region of the coin around the probable centre and beyond a probable edge thereof using the image of the coin, the edge region of the coin being imaged as an at least approximately sinusoidal line upon displacement of the probable centre to the exact centre, and the exact centre being determined from analysis of the at least approximately sinusoidal line using an amplitude and phase angle of a chosen starting point.

  • Patent number: 7032735
    Abstract: A coin slot for a mechanical coin-acceptor unit and a mechanical coin-acceptor unit having a coin slot aperture incorporated in a front plate, a coin slot chamber and a coin channel are proposed, the coin channel being offset relative to the coin slot aperture and the coin slot chamber having a shoulder behind the coin slot aperture in the insertion direction. The shoulder is configured so as to vibrate as a coin reflector or membrane in such a manner that an impacting inserted coin in the coin slot chamber is reflected by the shoulder elastically in the direction of the front plate and experiences, in the coin slot chamber, a renewed reversal of direction in the direction of the coin channel.

  • Patent number: 6615969
    Abstract: A mechanical coin checker is proposed having a coin channel which has a running rail for the coin to run down, in or at which channel checking arrangements are provided to check the properties of the coins, having a coin acceptance shaft and a return shaft, disposed below the running rail, to return coins which are not accepted. The running rail has in the running direction of the coin a recess into which coins which are too thin slide and possibly fall into the return shaft. In front of the coin acceptance shaft is disposed a detent pawl, which is rotatably mounted at a flap forming a part of the coin channel. A detent wire, which is pivotable about a portion of its longitudinal axis, co-operates with its one end region with the detent pawl and is disposed with its other end region below the recess, in such a way that when a coin slips through the recess, the detent wire pivots and takes the detent pawl with it into the coin channel to engage at least one integrally formed arm.
