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： An exciting circuit for a stepper motor requiring only a single decoder device yet being capable of controlling the speed of the stepper motor using plural different modes of excitation. A memory stores digital data representing a predetermined sequence of activation of the exciting coils. A counter drives the address input port of the memory in accordance with its output count. A clock signal generator supplies clock pulses to the counter in one of two patterns, representative of high and low speeds. The first of the patterns contains clock pulses spaced at equal intervals with a frequency such that the stepper motor can follow the corresponding changes in activation of the exciting coils of the motor. In the second pattern, the clock signals are supplied in bursts, the internal frequency of which is higher than the stepper motor can follow. In this latter case, portions of the normal excitation sequence are effectively omitted, thereby driving the motor at a different speed.

摘要： In a transfer type heat sensitive recording device a recording section is provided in which the thermal transfer of data is effected by applying thermal pulses to an ink donor sheet having a recording sheet superimposed thereon. Upon leaving the recording section, the recording sheet is separated from the ink donor sheet and upon completion of the separation, the drive for the ink donor sheet is terminated. A recording sheet discharge device is operatively driven from the ink donor sheet conveying device through a drive force accumulating mechanism so that upon stopping of the ink donor sheet conveying device, the torque accumulated by the drive force accumulating mechanism will be sufficient to continue the operation of the recording sheet discharging device until the recording sheet is fully discharged.
