In one embodiment the substrate is placed in contact with a larger heat sink which is heated by a carbon-type internal resistor, a printed circuit contacting resistor, or a conventional heater. A thermal sensor detects the temperature of the heat sink and is fed to controls for controlling the overall application of heat. In another embodiment the substrate is placed in contact with a Peltier effect device which controls heat generation and absorption.

摘要： In an image recording apparatus capable of recording a halftone image, a gradation to bit-train converting table converts gradation data representing a gradation of tone at a picture element of an image into bit-train data whose bit pattern is based on the gradation data. For the gradation data representing a gradation in excess of a threshold gradation, the table converts the gradation data into such bit-train data that bits of the bit-train data corresponding to the gradation data are intermittently omitted after a train of bits corresponding to the threshold gradation is outputted. A bit-train to pulse-train converting section converts the bit-train derived from the gradiation to bit-train converting table into pulse-train signal of a pulse pattern analogous to that of the bit-train data. The pulse signal of such a discontinuous pulse pattern is applied to a heating element of a thermal head, which is provided corresponding to the picture element whose gradation data is under process. A heating temperature of the heating element is controlled below a predetermined temperature.

摘要： A stepping motor exciting system in which the excitation current is set at one of four stepwise values. When the motor is to be driven in a stepwise manner, the excitation current is in the form of a pseudo-trapezoidal wave which is derived in terms of two of possible four values. When the motor is to be driven in a linear manner, the excitation current is in the form of a pseudo-sinusoidal wave which is derived in terms of all four possible values. A ROM stores these sequences of excitation currents and controls the exciting system in accordance with the driving mode desired.

摘要： An apparatus for exciting a step motor such as a step motor employed as a drive source for conveying original documents in a reading device such as a facsimile system. To vary the feed pitch in the auxiliary scanning direction of the original, staircase waveform exciting currents are applied through A-phase and B-phase exciting coils of the step motor. The apparatus of the invention provides for equal step sizes of the two waveforms and waveforms which are precise complements of one another. Currents flowing in the two exciting coils are sensed and voltages representing the sensed currents are divided in ratios determined by division ratio control signals read from a ROM. The divided signals are compared with a reference signal to provide pulse drive signals of constant currents during each step.

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.
