    摘要: 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.

    摘要: A thermal recording apparatus operates to efficiently utilize a smaller capacity power supply by the provision of a capacitor in parallel with the power supply source. The capacitor is discharged during printing cycles and is recharged in the interval between the end of one line printing operation and the beginning of the next. This interval is increased in proportion to the percentage of black bits printed in a given line, such that the capacitor may be sufficiently charged and the power supply efficiently used.

    摘要: A color copying machine includes a device separating the image information from each area of the original into colors corresponding to predetermined recording colors to thereby form corresponding video signals. A preferential selection circuit converts each video signal into a 2-level signal and performs an arithmetic operation on each 2-level signal to thereby key the image information from each area of the original to one of the recording colors or white. Black is selected as the recording color if a chromatic color competes with black in the same area.

    摘要: A multi-function copying machine having a reading section for reading picture data on an original by raster scanning. A recording section has a plurality of recording devices adapted to perform recording at different recording positions. The recording section applies to the recording devices a picture signal for each color for multi-color recording or a picture signal for each side of the original for two-side recording. Recording control is achieved by a control system for controlling the timing of delivery of the picture signal applied to the recording devices. An editing control circuit sets the timing of delivery of a part of the picture signal provided by the reading section to the recording section, for editing the picture data on the original. A memory delays the timing of delivery of a predetermined picture signal to the recording section according to the timing of delivery set by the control system.
