Abstract: A slot machine includes a plurality of rotary drums on the periphery of which plural frames of patterns are depicted. Detecting plates are connected to each rotary drum and the detecting plates are provided with pattern detecting elements whose number corresponds to the number of frames. Readers detect passage of the pattern detecting elements during drum rotation, and a control device counts the output of the readers and specifies the patterns positioned on a stop line based on the counted value after the drum stops. Each of the detecting plates provides for pattern confirmation which discriminates the pattern positioned on the stop line at least from the preceding and following frames of patterns when the drum is stopped, and the counted value is corrected in response to the pattern confirming device.

Abstract: Apparatus for measuring and analyzing the swing of a baseball player. The apparatus includes devices for emitting a plurality of spaced light beams projected in directions to be intersected by the swing plane of a bat and a corresponding plurality of light receiving elements arranged to receive light beams reflected from the bat. Signals received by the light receiving elements are collected and supplied to a processing apparatus and the results of this processing are displayed on a display unit which provides indication of angle, speed, level, etc. of the swing. The information may also be provided to a printer. The apparatus indicates whether the swing is performed normally and if it deviates from normal indicates the error involved.

Abstract: An automatic apparatus employed to simulate material conveying hardware and sensors to test control systems for factories and warehouses. The simulated conveying system is displayed on a color graphics CRT with the state of the input and output signals and a graphic representation of individual packages. Animation provided by the invention allows system operation to be observed. An attached operator's console has a command menu with functions to control the simulation. The simulated system may be started, stepped, stopped and the reaction of the control system observed on the color graphic CRT. Scenarios which represent the expected operation of the conveying system, may be set up to exercise the control system and determine system operation under stress or unusual operating conditions. The device may also be used to monitor an installed conveying system and provide diagnostic capabilities when actual operation does not meet expected operation.

Abstract: A game calculating apparatus includes a key unit consisting of a plurality of keys, a plurality of the display positions, and a complete game function processor operatively coupled to a random access memory and read only memory. A first symbol is variably displayed in each of said display positions either randomly or at specific cycle intervals during the game mode. To stop the movement of each said desired symbol a selected specific key must be actuated. The processor then determines the degree of exact matching of the signal representing the stopped first symbols and another signal representing a second set of symbols previously stored in the memory.

Abstract: There is disclosed a game apparatus employing a container having located therein an electronic circuit capable of emitting a repetitive audio signal of a controllable volume and repetition rate. The container includes a compartment in which a prize or award is placed by the players. The container is then hidden by one of the players who selects the repetition rate and volume to thereby cause audio signals to propagate. The participants then attempt to locate the container in response to the emitted signals and the first participant who finds the container has access to the prize. The degree of difficulty is determined by the volume and repetition rate of the signal as controlled by the player hiding the same.
