Abstract
A multicolor transfer heat-sensitive recording apparatus for thermally transfer-recording images onto a recording paper 1, comprises a first and a second thermal head for selectively heating ink donor sheets of different color, first and second drive feed units for drivingly feeding the recording paper and the ink donor sheets and a pulse generator for feeding pulses to the first and second drive feed units. The first and second drive feed units include first and second backing rollers, first and second stepping motors (such as synchronous inductor motors) drivingly connected to the backing rollers and first and second drivers for driving the stepping motors, respectively. The pulse generator simultaneously feeds for a predetermined duration a single pulse to the first driver for driving the first roller and a number of pulses to the second driver for driving the second roller. The number of pulses to the second driver being adjustable to possibly reduce a recording displacement due to dimensional differences of the rollers attendant to the first and the second thermal head.
