とを特徴とするフイルム給送制御装置。 In a film feeding control device having a film feeding mechanism that automatically winds the film for one screen by a motor after the photographing operation for one screen of the film is completed, the polarity of the drive power applied to the input terminal. A motor that rotates in the opposite direction by reversing the input terminal and continues to rotate for a short time even if electrical control is applied by cutting off the driving power supply and shorting the input terminal, and the input terminal of this motor. a motor drive means for switching and cutting off the polarity of the drive power applied to the drive power supply or short-circuiting the input terminal; a feed signal generating means for generating a predetermined number of pulse signals as the film is fed; After the operation is completed, the motor driving means is controlled to apply the driving power having the polarity to rotate the film in the winding direction to the input terminal of the motor, and then the pulse signal from the sending signal generating means is applied to the input terminal of the motor. After counting the pulse signals corresponding to one screen, the polarity of the drive power applied to the motor is reversed for a short period of time to apply a first braking, and then the drive power is cut off. and a control means for controlling the motor driving means so as to short-circuit an input terminal of the motor to apply a second braking.
