Abstract

1,252,850. Selective printing. NATIONAL CASH REGISTER CO. 19 Oct., 1970 [23 Oct., 1969], No. 49454/70. Heading B6F. A carriage drive mechanism for printing apparatus comprises a rotatable shaft 18 formed with an endless groove including a first helical portion 37 and a second helical portion 39 of opposite sense, and a follower 36 movable towards and away from the axis of the shaft 18 and mounted on the carriage 26 to engage the groove so that the first portion 37 drives the carriage in letter spacing direction, the second portion 39 then returning the carriage. The pitch of the second portion may be greater than, e.g. four times, the pitch of the first portion. The groove also includes an annular idling portion 35. The first portion 37 is deeper than the portion 39, and the idling portion 35 increases in depth in the direction of rotation of the shaft 18 and at its deepest point communicates with an accelerating portion 38 leading into the first portion 36, so that urging the follower 36 toward the shaft by an electromagnet 46 causes the follower to enter accelerating portion 38 and thus initiates letter spacing drive of the carriage. The carriage may carry type bars (28, Fig. 3) or an impression hammer for coaction with a typewheel (not shown).
