ABSTRACT:
A printing timing correction device in a shuttle type dot line printer wherein a shuttle is reciprocated in directions perpendicularly intersecting a direction of feeding printing paper, printing needles regularly arranged on the shuttle are projected to recording paper to thereby conduct desirable printing operations and the shuttle performs non-constant velocity motion for which the rotation of a driving motor is transmitted by a crank mechanism.
The printing timings are varied against the printing needles performing non-constant velocity motion in accordance with the speed of the printing needles, whereby the printings are performed at equal interval positions on the printing paper. This correction is performed by varying the delay time periods of signals fed to the printing needle driving device.
