1,167,362. Duplicating machines; typewriters. G. RITZERFELD. 28 Sept., 1966 [30 Sept., 1965; 10 Dec., 1965], No. 43355/66. Headings B6C and B6F. Data processing apparatus comprises a printing cylinder 12 or counter pressure roller 15 so that one or more lines from a master sheet 5 are printed on a copy sheet 13, an original sheet 1 read by magnetic, electrical or optical reading devices 9, 9b, means for effecting movement between the devices 9, 9b corresponding to one or more line spacings of the master sheet 5 in accordance with the operation of the printing cylinder and recording means 17 for recording the data read from the original sheet 1 e.g. in the form of punched holes P on to the same copy sheet 13 as printed on by the cylinder 12. Typewriters.-A typewriter for producing the original sheet 1 and the master sheet 5 has typelevers 3, Fig. 2, and between them and the platen and between the original and master sheet 5 is a carbon sheet 4. A minor script is produced on the back of sheet 5 by a dye sheet 6. The characters may be of known CMC 7 script readable by magnetic heads or two machines coupled together may be used, one typing in ordinary characters and the other magnetic data. Duplicating machine.-The process employs known rotary duplicating machines in which the master sheet 5, Fig. 4, is attached to a printing cylinder 12 and a counter pressure roller 15 is selectively operated from a keyboard so that one, two or more lines are printed on to the copy sheet 13. The mechanism rotating the printing cylinder 12 also feeds the copy sheets 13 and also drives the sensing heads 9, 9a, 9b, in a reader unit which senses the machine readable data on the original sheet 1, which is, as shown, mounted on a flat plate 7. For accurately aligning the lines to be read, illuminated slots 10 are provided over which the original sheet 1 is clamped. A second readable sheet 1a may also be provided to control printing by a separate mechanism on the cylinder immediately in front of the printing master sheet 5. In a further embodiment, Fig. 15 (not shown), the original sheets 1, 1a are clamped on a cylinder (153) arranged adjacent to and driven in synchronism with the printing cylinder. In each of these embodiments the sensing heads are moved in letter-spacing direction by a helical groove and follower and stepped for line-spacing by racks and pawls. The sensing devices may be magnetic or optical readers. Selectable data on printing cylinder.-The printing cylinder 12 may have selectable matter controlled by magnetic sensing of marks on the original sheet 1a.
