Abstract: Coin handling apparatus operative to pay out selectively presettable numbers of coins and automatically substitute paper money when the number of coins called for exceeds some arbitrary limit whereby risk of depleting the supply of coins by a succession of large withdrawals is alleviated, or alternatively to dispense some predetermined number of coins or an equivalent or other denomination of paper money or tickets depending on the adjustment of a value-setting switch.

Abstract: A transport device for a game machine which allows a plurality of coins to be automatically accepted into the machine to actuate a credit switch so that the machine can be enabled for energization rapidly and automatically.

Abstract: A coin agitating attachment for use on rotary coin transport discs fed by a coin hopper for coin-dispensing and counting machines. The attachment can be made in several configurations of elastomeric materials each characterized by at least a superficial resiliency of limited stiffness such that any point of impact with or by a coin presents a yieldable contact surface which is nevertheless sufficiently rigid to repel and drive the coins while retaining the original shape or configuration.

Abstract: A pinball game has a playing field with ball directing lanes and targets and flipper elements for returning the ball. A programmed logic array is connected to the switches, response lamps, digit scoring lamps, and audible devices. A matrix circuit is connected to the switches and places information into a memory, the output of which is connected through to activate lamps and audible devices which produce a continuous output if energized. A scanning decoder coupled to the matrix circuit is driven from the programmed logic array.

Abstract: A system for use in monitoring a plurality of amusement game devices is disclosed wherein individually identifiable attending personnel are employed to verify a predetermined game condition. The system is adapted for use with a computer and includes an interface unit connected to the computer and to a plurality of coupler units which are individually mounted on and interconnected with game devices. Each of the coupler units is adapted to receive a portable device for identifying individually each of the attending personnel. In the system illustrated in the drawings, that device is a transponder that locks into the coupler unit and provides informational responses to interrogation by the interface unit which sequentially polls or addresses each of the transponders.

Abstract: A game device comprising a plurality of reels which are rotated and stopped at random and in which each reel has different symbols arranged on its circumference and wherein the reel is made of magnetic material and is formed with openings such that one or more magnets mounted ajacent the reel will detect and produce an output that can be supplied to a counter so as to indicate the position where the reels stop and thus energize an output circuit. A second magnet mounted adjacent each reel can detect and produce an indexing output so as to reset the counter for each rotation of the reel. Additionally, a magnetic operated locking device for the reels are provided.

Abstract: An amusement apparatus having a plurality of symbol displaying elements, such as rotatable reels, with some of said symbols on the display elements being "Win" symbols having potential score values and others being "Hold" symbols without score values and said display elements adapted to randomly index in a viewing area during a play cycle a combination of said symbols with or without other symbols or "Blanks" having no value, and control elements associated with the changeable symbol display elements which are adapted to modify the random indexing of the symbols by holding automatically in indexed position in the viewing area any "Win" symbols during the play cycle immediately following a play cycle in which the "Win" symbol and a "Hold" symbol have been simultaneously indexed in the viewing area of the apparatus so that a winning combination of symbols may be automatically built-up in a series of play cycles before all of the symbol display elements are again changed and randomly indexed.

Abstract: A pin ball-type game with at least one bingo-type matrix on which a winning combination can be formed during play having a matrix transformation means for changing the matrix arrangement to enable a player to obtain a winning combination of maximum score value, and having a score value altering means associated therewith which a player has the option of activating whenever a said winning combination is formed on said matrix in place of accepting the regular score value for the combination, with the score altering means adapted at random to either double the score value normally awarded for the particular winning combinaton or awarding no score for the winning combination.

Abstract: A coin operated music machine which permits persons purchasing musical selections on the machine the opportunity of making additional selections over and above the amount of records and playing time to which he would be entitled by the deposit of coins into the machine. After the initial coin has been deposited into the machine, the player is offered the opportunity to make an additional coin deposit for which he may receive additional plays in addition to those purchased by the two coins. The right to receive the "Bonus Play" will be indicated on the machine but the player need not exercise the right to such play and can reject it by merely selecting the recordings which have been purchased by the deposit of the first coin. If the player decides to utilize the "Bonus Play" he will always receive the normal number of selections for the second coin but may additionally receive extra plays above the normal number of selections for a coin.

Abstract: A coin acceptor to prevent a cheating operation known as "stringing" wherein a coin is dropped into such an acceptor with a string attached and manipulated in a manner to make it appear that several coins have passed through the acceptor. This coin acceptor uses a series of coin position detectors with a counting circuit for sensing the sequence in which the coin passes the detectors.

Abstract: In a pin ball game apparatus a Bingo-type score card having a shiftable mask plate associated therewith for changing the score value of a winning combination where the mask plate is reciprocably movable vertically in opposite directions from a center position relative to the score card by a rotatable cam connected to a lever arm supporting the mask plate, a locking mechanism associated with the lever arm which restrains the movement of the mask plate away from the center position in at least one direction, and a spring biased linkage interposed between the rotatable cam and the lever arm which permits the cam to be rotated 360.degree. while the locking mechanism restrains movement of the mask plate away from the center position in at least one direction.

Abstract: An auxiliary fraud-deterrent guard method and means for use with handle-operated reel-spinning mechanisms such as poker, fruit and slot machines which employ a trip lever requiring complete, non-retrogressive movement of the operating handle for initiation of a proper operating cycle, wherein retrogression is prevented by a blocking dog which enters behind the advancing trip lever and is automatically displaced to non-obstructing position by the decoupling action of a pawl which frees the trip lever from the handle at trip-out position. An additional feature provides a simple adaptor means mounting the dog for quick installation on existing equipment.
