Abstract
The selector device for a character-carrying element of a printing machine comprises a d.c. electric motor whose rotor is capable of selectively rotating in both rotational directions a coupling arrangement comprising a pinion on the motor shaft and a gear on the shaft which carries the hub for mounting a daisywheel printing element and a strobe disc which provides the position signals used to control character selection. A device for taking up clearances minimizes the radial clearances between the pinion and the gear. Thus the motor is mounted on trunnions and urged by a spring to tilt in the sense urging the pinion into the gear.
