Printer, provided with an impact device comprising a transducer

A printer comprising an impact device including an impact member displaceable from a rest position in the direction of a record carrier by means of an electro-mechanical drive, the impact device further comprising a transducer which, during a displacement performed by the impact member, supplies a signal indicative of the speed of the impact member, means connecting a signal output of said transducer to a first signal input of a comparator which includes a second signal input and a signal output terminal for deriving a stop signal, means connecting a reference signal device to said second signal input of the comparator, means connecting said comparator signal output terminal to a signal input terminal of an electrical actuation device coupled to said electromechanical drive of the impact member, means responsive to a start signal for actuating said electromechanical drive via said actuation device, the actuation of the electromechanical drive being terminated only after the appearance of the stop signal at the signal output terminal of the comparator, and calculating means coupled to the transducer output for deriving a control signal determined by the speed and position of the impact member, and means coupling an output terminal of the calculating means to a control input of the actuation device so that said control signal controls the amplitude of an actuation current supplied to the electromechanical drive of the impact device.
