Consequently, the account sheet 5 is carried forwards until lower sensors 10a, 10b detect the account sheet 5. By the detection, a pinch roller-stopping signal oscillator 18 and a timer 19 are actuated, so as to stop the operation of the pinch rollers 6, 7 and to release the pinching state by a magnet means 15. Consequently, the account sheet 5 is arranged on a stopper 9', orderly aligned at its front end. The roller 6, 7 are then driven by a signal from the timer 19, and the stopper 9' is also removed concurrently.

Filed: 1982-03-26
Abstract: PURPOSE:To improve the operation etc. of an internal-combustion engine which is supplied with a thin mixture in a prescribed range of operation, by stopping the recycling of exhaust gas throughout the operation of the engine in the prescribed range. CONSTITUTION:A controller 50 calculates the quantity Q/N of intake air per stroke of an engine from the outputs of an air flow meter 15 and a rotational frequency sensor 29. When the quantity Q/N is larger than a prescribed level A but smaller than another prescribed level B (B>A) and the rate of the change in the quantity is less than a prescribed value, the controller 50 judges that the engine is in a prescribed operation range which corresponds to normal operation under low or medium load. At that time, a basic fuel injection time is shortened at a predetermined ratio to determine an effective fuel injection time to control a fuel injection valve 20 so that a thin mixture with an air fuel ratio larger than a theoretical air fuel ratio is supplied to a combustion chamber 5 through an intake port 6. In said operation range, a solenoid valve 46 is opened to an atmosphere port 47 and an exhaust gas recycle valve 32 is closed to stop the recycling of exhaust gas.
