Title: Tabulation control for printing head transverse movement - switches from rapid drive to path-dependent control close to required printing position
Inventor: STOECKLER KURT
IPC: G05B19/23
Filed: 1980-02-23
Abstract: The tabulation control uses the difference between the actual and required positions to select the drive rate for the printing head drive (4). When the difference between the two positions is large the drive rate is controlled by an oscillator with a preselected constant frequency. When a specific difference between the two position values is reached the drive (4) is switched to a position dependent control using a position indicator (6) running along the line of travel of the print head (2). Pref. a second oscillator providing a train of leading or lagging pulses is used between drive control via the fixed frequency oscillator and that via the head position. The required position is held in a store with pulses from the position indicator fed to a counter, while a second counter receives pulses from the oscillators, so that the position difference is given by the stored value and the count values of the two counters.
