    摘要： A thermoelectric power generating timepiece (1) comprises a dial (30), a movement (40), and a heat conduction sheet (50), provided within an enclosed space, defined by a case (10) made of metal, with a glass (20) fixedly attached thereto, and a case back (70), and further comprises a thermoelectric element (60), housed in a gap between the heat conduction sheet (50) and the case back (70). The case back 70 is made of two kinds of materials each having a thermal conductivity differing from that of the other. The case back (70) is made up of a heat conducting part (71) made of material, such as metal, and the like, having a high thermal conductivity, and formed in a shape larger in outer size than the thermoelectric element (60), so as to be disposed opposite to the thermoelectric element (60), and a heat insulating part (72) made of material having a low thermal conductivity such as plastics, and the like, and formed so as to be disposed on the outside of the heat conducting part (71).

    摘要： A timing pulse generator for a serial printer, which generator outputs a print timing pulse at a timing necessary for accurately controlling movement of the print head. In this timing pulse generator, an edge detection circuit outputs a pulse signal each time it detects the rising edge of an encoder signal output in response to movement of the carriage. A timer circuit measures the pulse period between two succeeding pulse signals output from the edge detection circuit. A first storage circuit outputs the stored previous pulse period and overwrites the storage area with this new pulse period. A second storage circuit outputs the stored pulse period immediately before the previous pulse period and overwrites the storage area with the previous pulse period output from the first storage circuit. A subtraction circuit calculates the difference between the previous pulse period and the pulse period immediately before the previous pulse period, after which an addition circuit adds this difference to the previous pulse period to obtain an estimated value or a pulse period equivalent to the current velocity of the carriage. Finally, the estimated value is divided by a prescribed value based on the printing resolution to generate the print timing pulse that provides the print head drive timing.

    摘要： A reference pattern is printed on one of the printing regions as the printing head moves in one direction, and a comparison pattern, which is to become a pattern identical to the reference pattern, is printed on the other of the printing regions as the printing head moves in both directions. A judging process is provided in which the comparison pattern is compared with the reference pattern so as to judge whether the two patterns are identical or not. The relative positional relation is determined to be proper if the two patters have been judged to be identical.

    摘要： A waveform processing circuit for a pulse generator provided between the pulse generator and a motor control circuit, comprises a frequency dividing circuit and a control signal generation circuit. The frequency dividing circuit outputs, on the basis of an A-phase pulse signal and a B-phase pulse signal outputted from the pulse generator, a pulse signal having a duty ratio of 1:1 and being inverted in response to rise of the A-phase pulse signal and a pulse signal having a duty ratio of 1:1 and being inverted in response to fall of the A-phase pulse. The control signal generation circuit generates, on the basis of these two pulse signals, a traveling amount signal and a direction discrimination signal. Thus, the motor control circuit carries out, on the basis of the traveling amount signal and the direction discrimination signal, motor control without undergoing the influence of a duty ratio of the pulse generated from the pulse generator.

    摘要： A printer having a device for advancing and retracting a print head toward and away from a paper supporting platen, an automatic head gap adjusting device for controlling the head advancing and retracting device, to advance the print head until the print head comes into contact with a recording paper, and then retracting the print head by a predetermined distance, to thereby adjust a head gap between the paper and the print head, and an operator-controlled head gap adjusting device for manually operating said head advancing and retracting device, to thereby adjust the head gap. A mode selector is provided for selecting one of an automatic adjusting mode in which the head gap is adjusted by the automatic head gap adjusting device, and a manual adjusting mode in which the head gap is adjusted by the operator-controlled head gap adjusting device.
