PCT No. PCT/US84/00095 Sec. 371 Date Feb. 17, 1984 Sec. 102(e) Date Feb. 17, 1984 PCT Filed Jan. 20, 1984 PCT Pub. No. WO85/03255 PCT Pub. Date Aug. 1, 1985.A print disk positioning system is disclosed herein which provides rotational and lateral movement of a print disk (20) having raised or depressed characters thereon with the objective of locating the appropriate character within the jaws of a printing station (22). The positioner includes a fixed rail (44) which is driven by the rotation of a motor (38) having a pinion gear (42) which drives a rack gear (82) connected to a rack arm (80) which in turn slides a second motor (54) mounted on bearings (56) on rail (44). Motor (54) provides the rotational movement to the disk and motor (38) provides the lateral movement. Each motor is controlled electrically to cause an appropriate sequence of movements to bring the disk into proper alignment in the printing station at the appropriate time.
