Abstract
The print head carriage for a printer has end-mounted toothed clutches secured thereto and engageable with mating toothed clutches mounted on the carriage support shaft for rotation thereof upon near end of travel of the carriage across the printer. The teeth of the carriage mounted clutches are one-half pitch length out of phase with the teeth of the mating clutches so that, at each end of carriage travel, the mating clutches are caused to be incrementally rotated to thereby rotate the carriage support shaft and the record media drive shaft for advancing the record media a predetermined distance.
Claims17
Means for advancing record media past a working station comprising:
- support means mounted for rotational movement,
- carriage means carried by said support means and movable therealong past said working station,
- first clutch means secured to said carriage means for travel therewith,
- second clutch means mounted on said support means for rotational movement of said second clutch means in response to engagement by said first clutch means, and
- means operably associated with said second clutch means for causing incremental movement of said record media upon engagement of said second clutch means by said first clutch means during traversal of said carriage means along said support means.
In a printer having a platen and a print head operable therewith, support means journaled on said printer for rotational movement, and means for advancing record media in a path between said platen and said print head including a print head carriage movable back and forth along said support means, clutch means on said printer and carried on said support means for rotational movement therewith, clutch means on said carriage engageable with said printer clutch means for incremental rotary movement thereof in response to movement of said carriage, and means operably associated with said printer clutch means for causing incremental movement of said record media along said path upon engagement of said printer clutch means by said carriage clutch means.
