In a notifying device comprising a notifying unithaving incorporated therein a vibrator to be resonated by a drive signal fed thereto, and a signal preparing circuitfor feeding the drive signal to the notifying unit, the signal preparing circuitprepares a drive signal Dv varying in frequency within a predetermined range including the resonance frequency of the vibrator of the unitand feeds the signal to the notifying unit. The variation of frequency of the drive signal is determined in correspond relation with a variation in the resonance frequency of the vibrator due to tolerances for specifications which govern the resonance frequency. The drive signal has an alternating waveform of rectangular waves or sine waves, and the frequency thereof varies periodically from 1.37 to 2.98 Hz. The notifying device achieves a satisfactory notifying effect despite the variation of the resonance frequency of the vibrator.

A question as to the physical condition and a question as to the feeling are asked, answers are accepted by voice, acoustic features are extracted from the answer to the question as to the physical condition, and character string information is extracted from the answer to the question as to the feeling. A correlation between the acoustic features and the character string information is set, and character string information is identified from a newly accepted acoustic feature, thereby performing feeling presumption. Feeling is presumed from the voice in response to the subject's severalty and changes in the subject's age and physical condition. A medical examination by interview on the mental condition is performed on the subject by voice output and voice input, and the subject's mental condition is diagnosed based on the contents of the subject's answer and analysis of the answer by voice.

A method of controlling printed density in thermal transfer printing includes the steps of: forming a density table representing relation between input energy and actual printed density when there is no temperature gradient in a thermal head; determining a temperature gradient coefficient for estimating a temperature gradient between a heating element and a temperature detector in the thermal head for the nth line; and calculating density correcting amount based on a ratio of the temperature gradient coefficient of the nth line to the temperature gradient coefficient when the thermal head is at a steady temperature gradient state. Apparatus is also provided for carrying out the method.

A printer wherein a piece of recording paper housed in a cassette is picked up and sent to a platen roller which is made to rotate in the direction of leading the sent recording paper to the printing position, hereupon one piece of recording paper to be sent to the printing position is separated from the other pieces, the latter pieces being sent back in the reverse direction to the printing position, by rotating a separation roller positioned against the platen roller in the same direction as that of the platen roller rotation.

Printer

A thermal transfer recording apparatus, such as a thermal transfer printer, which winds up at constant speed an ink sheet having ink to be transferred while applying a constant tension to the ink sheet by a DC motor through a speed reduction mechanism, so that the respective rotation speed and torques, when a wind-up roll is of a minimum diameter or a maximum diameter, are computed from the feed speed and tension of the ink sheet to thereby obtain a desired gradient in a chart of the relationship between the torque and the rotation speed of the DC motor, the gradient deciding a reduction ratio of the deceleration mechanism and the driviing voltage of the DC motor being decided. Hence, even though the wind-up roll varies in an external form, variation in tension applied to the ink sheet and that in the feed speed can be restricted.

The thermal transfer printer of the present invention prevents slackening of recording paper by exerting a braking force upon a recording paper roll to give a back tension to the recording paper when one of the colors of an ink sheet coated with inks of a plurality of colors is thermal-transfer-printed. The recording paper is unwound from the roll thereof in the forward direction and by rotating the recording paper roll in the backward direction the recording paper is rewound. A roller for carrying the recording paper is stopped or braked at the downstream side of the platen when the recording paper is carried in the backward direction for the thermal transfer printing by the next color.
