Abstract: PURPOSE:To enable a mirror to be reliably reproduced in a memory position even if the frequency of an oscillator is changed due to a change in temperature environment, by a method wherein a relative relation between an oscillation frequency in a mirror position during memory and an oscillation frequency in a mirror position serving as reference is stored. CONSTITUTION:After a mirror 1 is set in an optimum position to a driver, a memory switch 12a is turned ON, and the oscillation frequency of a mirror memory position from a coil type oscillator 9 is measured by a control circuit 10. Thereafter, by means of an instruction signal, the mirror is displaced to a reference position, and the frequency in the reference position is measured in a similar manner. From said two oscillation frequencies, a frequency changing rate is calculated to store it. When a mirror position is reproduced, a reproduction switch 12b is turned ON, and by means of an instruction signal, the mirror is brought to a reference position. From a frequency in this position and said frequency changing rate, a given frequency is calculated. With a motor 4 run, the mirror is moved, and when the frequency of the coil type oscillator 9 coincides with said given frequency, the motor 4 is brought to a stop.

Abstract: PURPOSE:To achieve a high definition color halftone recording at a low power consumption and at a high speed by employing a heat generating resistor whose resistance value increases sharply above a certain temperature while the distance between electrodes changes gradually across the width of the heat generating resistance. CONSTITUTION:Given information existing on a signal electrode 28a, when DC voltage is applied between both electrodes the distance between which is not constant, current flows concentratedly to the smallest parts of the distance between the electrodes to heat the parts 30a and 30b up to a high temperature to perform a print recording with dots of the area corresponding to the parts 30a and 30b. With the further application of the voltage, the resistance R reaches a certain temperature, for example, 250 deg.C and begain to increase the resistance value sharply until the resistance values of circuits 32 and 33 equal, so that the same amount of current flows through the circuits 32 and 33. The heat generating part grows to the portions 31a and 31b enabling a print recording with dots of the area corresponding to 31a and 31b. The continued application of voltage makes the resistor of a circuit 34 higher in the temperature thereby enabling the print recording with dots of the are corresponding to one entire resistor.
