An automatic apparatus for controlling injection amount comprises an injection speed control means reference injection amount control means and injection amount control means. An oscillator(1) is coupled to an OR gate(6); the other(2) which is operation faster than the oscillator to an AND gate(5) through a one-shot multivibrator(3) which is controlled by a conderser(C1) and a variable resistor(R1). The other one-shot multivibrator is also coupled to the AND gate(5) with a switch connected. The injection amount is controlled with an ON/OFF operation of the switch.
