1. An amusement device for producing one of a plurality of possible output indications selected by chance including in combination counter circuit means operable to be switched through a predetermined recurring sequence of operating states by triggering pulses applied at the input thereto, and operable to remain in an operating state in the absence of triggering pulses;

  • pulse generating means connected to the input of the counter circuit means and operable to produce triggering pulses during the occurrence of an energizing signal at a control connection;

    manually-operated switch means connected to the control connection of the pulse generating means and operable to produce said energizing signal when actuated; and

    output means connected to the counter circuit means and operable to provide an indication of the operating state of the counter circuit means;

    said pulse generating means including Schmitt trigger circuit means operable to produce a continuous train of pulses at its output in response to a first voltage condition being preseNt at its input and operable to cease producing said continuous train of pulses at its output in response to a second voltage condition being present at its input, resistance-capacitance delay means coupled to the Schmitt trigger circuit means and operable to cause a delay in the operation of the Schmitt trigger circuit means in producing said pulses at its output in response to the occurrence of said first voltage condition at its input, and inverting gate means having a first input connection connected to the output of the Schmitt trigger circuit means and a second input connection constituted by said control connection, and an output connection connected to the input of said Schmitt trigger circuit means, said inverting gate means being operable while said energizing signal is present at its control connection as a result of said switch means actuation to produce the first voltage condition at its output connection, said inverting gate means being operable while said energizing signal is absent at its control connection as a result of said switch means deactuation to produce the second voltage condition at its output;

    whereby actuation of the manually-operated switch means causes the counter circuit means to be switched continuously through the predetermined recurring sequence of operating states by triggering pulses from the pulse generating means, and termination of actuation of the manually-operated switch means causes the counter circuit means to stop switching and the output means to provide an indication of the particular operating state of the counter circuit means upon termination of actuation of the manually-operated switch means.
