Abstract
1,188,637. Selective printing. ING C. OLIVETTI & C S.p.A. 1 Jan., 1969 [29 Jan., 1968], No. 141/69. Heading B6F. A selective printer comprises a flat or dishedtype disc 14 of elastically flexible material such as steel, slotted as at 18 to provide a plurality of type-bearing sectors 17, the disc 14 being continuously rotated by a motor (not shown), driving a belt 9 through a pulley 10, a print hammer 20, and a photo-electric sensing device providing signals indicative of the angular position of the disc to determine the instant of impact of the hammer, the disc 14 being removably mounted on a disc support carriage 3 so as to be interchangeable with other type discs. The sensing device comprises a light source 44 which transmits light through the slots 18 to a photo-electric cell (45), Figs. 2, 3 (not shown), coupled to a counter, the counter being zeroized by a second photo-electric cell (46) when a larger slot 19 passes the source 44. Hammer impression arrangements.-The hammer 20 is pivotally mounted on a post 21 fixed to the carriage 3 and is urged by a spring 22 to engage a stop 23. The stop 23 is fixed to an armature 26 of an electromagnet 27 which when energized impels the hammer towards the disc 14, the hammer arm striking a post 62 so that the arm completes its travel under its own momentum. The hammer head 29 is pivoted to the arm 28 at 30 and coupled to the arm by a spring 31, to prevent the head from fouling sectors 17 of the disc 14 after an impression operation. Letter spacing.-A motor (not shown), which may also drive the disc 14, continuously drives gears 39, 37, the gear 37 frictionally engaging a ratchet wheel 35 owing to a spring 38. A pawl 36 normally prevents rotation of the ratchet wheel 35 but may be disengaged therefrom by an electromagnet 43 which may be energized in response to a pulse from the second photo-electric cell (46). Rotation of the ratchet wheel 35 by one tooth steps the carriage 3 one letter space through a screw 6 and nut 34. Type wheels; case shift mechanism.-The sectors 17 may each bear two type characters, the disc 14 being lifted as a whole for case shift. In a modification, the type-bearing disc may be dished (Fig. 4, not shown), so that the sectors (48) bearing the type are parallel to the rotational axis (54) of the disc, case shift being effected by axial movement of the disc by an electromagnet (61). The type disc is removable to permit a variety of input codes to be used. Carriage guides and races.-The carriage 3 runs on a guide 4 by means of rollers 5 mounted on ball-bearings.
