What is claimed is: 1. An air conditioner for use in vehicles comprising: a compressor connected to an engine driving a vehicle and operated by a driving force provided by said engine during operation of said engine, wherein in response to stopping of said engine, a connection between said engine and said compressor is released, and an electric motor, which drives said compressor, is connected to said compressor; said electric motor, which drives said compressor, is connected to an inverter, and receives an electric power supply via said inverter, said compressor being operated by said electric motor during stopping of said engine; and a separately provided motor generator receives an electric power supply via said inverter from a DC power supply to start said engine, and is driven by said engine during operation of said engine to perform a power generation function. 2. The air conditioner according to claim 1, wherein said electric motor is controlled in rotational speed by velocity control means, and drives said compressor at a predetermined rotational speed controlled by said velocity control means upon stopping of said engine. 3. The air conditioner for use in vehicles according to claim 1, further comprising a one-way clutch providing a connection between said compressor and said electric motor driving said compressor; and said one-way clutch holds the connection between said compressor and electric motor when said compressor is driven by said electric motor, and releases the connection between said compressor and electric motor when said compressor is driven by said engine. 4. The air conditioner for use in vehicles according to claim 2, further comprising a one-way clutch providing a connection between said compressor and said electric motor driving said compressor; and said one-way clutch holds the connection between said compressor and electric motor when said compressor is driven by said electric motor, and releases the connection between said compressor and electric motor when said compressor is driven by said engine. 5. The air conditioner for use in vehicles according to claim 1, further comprising an electromagnetic clutch and a reduction mechanism connecting said compressor to said electric motor driving said compressor; and said compressor is driven by said electric motor via said electromagnetic clutch and reduction mechanism during stopping of said engine. 6. The air conditioner for use in vehicles according to claim 2, further comprising an electromagnetic clutch and a reduction mechanism connecting said compressor to said electric motor driving said compressor; and said compressor is driven by said electric motor via said electromagnetic clutch and reduction mechanism during stopping of said engine. 7. The air conditioner for use in vehicles according to claim 1, wherein said motor generator receives the electric power supply via the inverter from the DC power supply to start said engine, at the same time the motor generator is driven by said engine during operation of said engine to perform a power generation function; and said electric motor, which drives said compressor, is connected to said inverter in response to stopping of said engine, and receives an electric power supply via said inverter. 8. The air conditioner for use in vehicles according to claim 5, wherein said reduction mechanism reduces input rotational speed from the electric motor. 9. The air conditioner for use in vehicles according to claim 3, wherein said one-way clutch is located between the motor generator and the compressor. 10. The air conditioner for use in vehicles according to claim 1, further comprising a first electromagnetic clutch located between the compressor and the engine and a second electromagnetic clutch located between the compressor and the electric motor. 11. The air conditioner according to claim 1, further comprising a first electromagnetic clutch located between the compressor and the engine and a second electromagnetic clutch located between the compressor and a reduction mechanism. 12. The air conditioner according to claim 1, further comprising a first electromagnetic clutch located between the compressor and the motor generator and a second electromagnetic clutch located between the compressor and the electric motor. 13. An air conditioner for use in vehicles comprising: a compressor connected to an engine driving a vehicle and operated by a driving force provided by said engine during operation of said engine, wherein in response to stopping of said engine, a connection between said engine and said compressor is released, and at the same time, an electric motor, which drives said compressor, is connected to said compressor, and said electric motor, which drives said compressor, is connected to an inverter, and receives an electric power supply via said inverter, said compressor being operated by said electric motor during stopping of said engine; and a separately provided a motor generator that receives an electric power supply via an inverter from a DC power supply to start said engine, and is driven by said engine during operation of said engine to perform a power generation function. 14. An air conditioner for use in vehicle comprising: a compressor connected to an engine driving a vehicle and operated by a driving force provided by said engine during operation of said engine, wherein in response to stopping of said engine, a connection between said engine and said compressor is released in response to stopping of said engine, and an electric motor, which drives said compressor, is connected to said compressor, wherein said compressor is operated by said electric motor during stopping of said engine; a first electromagnetic clutch located between the compressor and the engine and a second electromagnetic clutch located between the compressor and the electric motor; wherein said electric motor, which drives said compressor, is connected to an inverter, and receives an electric power supply via said inverter. 15. An air conditioner according to claim 14, wherein said first electromagnetic clutch is in an on state during starting of the engine and the second electromagnetic clutch is in an off state during starting of the engine.
