ROTATABLE POINTER DRIVEN AND INDEXED BY THE ROTOR OF AN ELECTRONICALLY CONTROLLED MOTOR HAVING PERMANENT MAGNET POLES |
摘要 |
An electronic game which includes a motor with its output shaft connected to a non-integral gear train for driving a pointer and in which the pointer may randomly stop at any of a number of discrete positions. The motor is energized in response to contact made by the user between a pair of terminals and the motor rotates the pointer such that it stops in a random manner after the circuit has been interrupted with the indexing depending unpon the permanent magnets of the motor stopping the rotor of the motor at discrete positions.
