Abstract: A printer capable of printing high-quality recording is provided. A driving force transmission gear mounted on a platen roller, driven rollers mounted on a pair of conveying rollers, respectively, and intermediate gears that always mesh with both the driving force transmission gear, and the driven rollers form a re-transmission mechanism that re-transmits the driving force transmitted to the platen roller from a driving motor to each of the one pair of conveying rollers. Also, gear supporting shafts that rotatably support intermediate gears are configured so as to be adjustable in position.

Abstract: The present invention provides a thermal printer in which, even if a pair of head supporting members for supporting a thermal head composed of a line head has a positional error, the thermal head can be automatically adjusted to uniformly pressure-contact with a platen roller. A rotation supporting portion of a head supporting member is formed in a hole shape elongated in a direction parallel to a direction where a thermal head contacts with or separates from a platen roller. One end of each of the head supporting members is supported by a main body case so as to be movable in a direction parallel to the direction where the thermal head contacts with or separates from the platen roller.

Abstract: A compact disc transporter has been described that includes a two-step printer. The printer uses an intermediate transfer sheet to receive a print image that is subsequently transferred to a compact disc. The transporter allows parallel processing of image data and content data. A significant time reduction can be achieved by pre-printing the image to a transfer sheet prior to transferring the image to a CD.

Abstract: The present invention provides a thermal printer in which, even if a pair of head supporting members for supporting a thermal head composed of a line head has a positional error, the thermal head can be automatically adjusted to uniformly pressure-contact with a platen roller. A rotation supporting portion 7b of a head supporting member 7 is formed in a hole shape elongated in a direction parallel to a direction where a thermal head 5 contacts with or separates from a platen roller 4. One end of each of the head supporting members 7 is supported by a main body case 2 so as to be movable in a direction parallel to the direction where the thermal head 5 contacts with or separates from the platen roller 4.

Abstract: The thermal transfer line printer is provided with tension roller position detection means having tension rollers, rotatable tension roller support frames that support the tension rollers rotatably and press the tension rollers toward an intermediate sheet, and a detector and a sensor for detecting a position of the tension rollers and is provided with a controller for controlling operation of an intermediate transfer sheet feeding motor that moves at least the intermediate transfer sheet, and the controller controls the intermediate transfer sheet feeding motor so as to position the detectors in a detection range of the sensors when the intermediate transfer sheet is moved.

Abstract: An air-bubble detection apparatus which detects the presence or absence of the occurrence of air bubbles in an ink passage by detecting if the voltage which develops across an electrostrictive vibrator by mechanical strain as a result of the ink in the ink passage of an ink jet recording head being moved, exceeds an excess voltage above a drive voltage. In addition, a method and apparatus for restoring the recording head to its operating condition, which prevents ink and energy from being wasted and makes efficient printing possible by restoring the recording head in which the occurrence of air bubbles is detected by using the above air-bubble detection apparatus.

Abstract: A method of detecting an ink residual quantity in an ink jet printer, which is capable of eliminating a possibility of blank printing even when effecting a print on the large-sized paper by detecting the ink residual quantity at a high frequency and of keeping a good printing efficiency. The ink residual quantity is detected in an equispeed motion area of the carriage. The ink residual quantity can be stably detected per line without stopping the carriage and providing a special liquid level oscillation preventive mechanism.

Abstract: The present invention relates to an angular initialization method for orientating a direction of a cutting edge portion in a cutting plotter which cuts out a cutting medium into a desired shape sheet, in which a cutter member is continuously shifted to cut out the cutting medium along two line segments from a first line segment to a second line segment which intersect with each other at a predetermined angle, and it is possible, when the cutter member is shifting on the second line segment, to change the direction of the cutting edge portion and to securely locate the direction of the cutting edge portion to coincide with the second line segment shortly before a cutting operation is commenced, even if the cutter member is not turned to a desired cutting direction while the cutter member has been shifting on the first line segment.

Abstract: A pen exchange mechanism is disclosed, by which a plurality of pen chuck mechanisms holding pens on a carriage are disposed, and a slider is engaged with the carriage at a position corresponding to a pen, which should print, among said pens, printing being effected while driving a pen chuck mechanism at a position corresponding to the slider together with the pen by means of a pen driving mechanism.

Abstract: In a pen pressure device including a carriage, a pen axially movably supported to the carriage in such a manner that a front end of the pen is opposed to a paper, a pen pressure spring for biasing the pen toward the paper, a return spring for biasing the pen in a direction apart from the paper; the improvement comprises a hammer mounted on the carriage and adapted to be biased by the pen pressure spring having a spring force greater than that of the return spring to thereby urge the pen, and a cam member for moving the hammer to a retracted position where the pen is not urged by the hammer.

Abstract: A multi-stage printer has an arithmetic section for calculating the next paper moving amount on the basis of a line position of a selected type stage of a plurality of type stages; printing is performed by a desired number of digits in a first line position by using first types selected from the groups of types; then, the distance from the printed first line position to a printed state-confirmable position away from the area opposed to the groups of types is calculated by the arithmetic section and the printing paper is moved by the paper moving means by an amount based on the result of the calculation thereby allowing the printed first line position to be moved up to the confirmable position; then, before printing in a second line position by using second types selected from the groups of types, the distance from the printed first line position now occupying the confirmable position to the second selected types is subtracted from a predetermined printing inter-line pitch in the arithmetic section and the pri
