Claim 9

A running control apparatus for a moving vehicle in accordance with claim 7 wherein said control means comprises means for determining whether further rotation of said vehicle is necessary in order to assume said attitude wherein said central axis of said vehicle corresponds to said direction, and for terminating rotation of said vehicle when peak signals from said reflectors are received by said photoelectric sensors.

Claim 10

A running control apparatus for a moving vehicle in accordance with claim 8 wherein said means for determining comprises means for detecting excessive turning of said vehicle with respect to said direction and for generating correction signals to correct said excessive turning.

Claim 11

A running control apparatus for a moving vehicle in accordance with claim 8 wherein said means for determining comprises means connected for receiving an output from said photoelectric sensors, means connected for receiving said output signals representative of rotation of said vehicle from said control means responsive to said wheel rotation signals and for generating control signals to activate driving means for the wheels moving said vehicle in order to attain said direction.

Claim 12

A running control apparatus for a moving vehicle in accordance with claim 1 further comprising rotation detecting means connected for detecting an amount of rotation of wheels moving said vehicle and for producing wheel rotation signals representative thereof.

Claim 13

A running control apparatus for a moving vehicle in accordance with claim 11 wherein said means for fixed point turning said moving object further comprises control means responsive to said wheel rotation signals for determining an amount of rotation of said vehicle and for producing an output signal representative of the rotation of said vehicle.

Claim 14

A running control apparatus for a self-propelled vehicle, comprising: photoelectric means including scanning means rotatably mounted on said vehicle, rotating means for rotating said scanning means, said photoelectric means including a pair of light receiving means, a pair of reflectors at predetermined target positions opposing said light receiving means, first means for stopping the vehicle when the light receiving means of said photoelectric means each substantially simultaneously receives light reflected by corresponding ones of said reflectors, means for fixed point turning said vehicle, first rotation detecting means connected for detecting an amount of rotation of wheels moving said vehicle and for producing wheel rotation signals representative thereof, said fixed point turning means comprising control means responsive to said wheel rotation signals for determining an amount of rotation of said vehicle and for producing a vehicle rotation signal representative of the rotation of said vehicle, means for activating said rotating means for said scanning means to rotate said scanning means until a predetermined signal is received from said light receiving means and for generating a scanning means rotation signal, and means responsive to said scanning means rotation signal to generate a control signal for activating driving means for the wheels moving said vehicle to rotate said vehicle in accordance with said scanning means rotation signal.
