    • A miniature magnetic disk device or a miniature optical disk device has a recording disk having a diameter less than or equal to 0.7 inches. The disk device also includes a spindle motor which rotates the recording disk, a read/write head for recording or reproducing information on and from the recording disk, a support member which holds the read/write head, and a support shaft which is coupled to the support member. A voice coil motor, which is coupled to the support member and the support shaft, sets the read/write head in a desired position over the disk. A resistor which has a value of at least 2.5.OMEGA. is connected in series with a coil of the voice coil motor, and the resistor makes it possible to reduce power consumption of the voice coil motor. The resistor may be a variable resistor, and a conductor of the coil may have a cross-sectional area less than 2.55.times.10.sup.-3 mm.sup.2. A ratio h/t of a thickness h of the coil to a thickness t of a magnetic circuit of the voice coil motor have be at least 0.25. Moreover, by mounting several of these disks on a board which is standardized as PCMCIA type 3, a miniature array disk device is formed.

    • A thermal transfer printer including a thermal head for generating heat in accordance with a desired print pattern, a platen having a surface for supporting an ink-sheet and paper, the ink-sheet and paper being pressed by the thermal head on the platen surface so that ink from the ink-sheet is transferred to the paper, a paper supply for storing and supplying paper, an ink-sheet supply and drive for storing and supplying an ink-sheet, the ink-sheet supply and drive driving the ink-sheet to move in accordance with the movement of the paper, a paper drive arranged between the platen and the paper supply, the paper drive driving the paper by the required length according to the position of the paper relative to the position of the platen, and a paper tension device for applying suitable tension to the paper at least between the platen and the paper drive so that the length by which the paper drive drives the paper is identical with the length by which the paper moves on the platen. Since the length by which the paper moves on the platen corresponds only to the length by which the paper drive drives the paper, the length by which the paper moves on the platen can be correctly controlled through the paper drive.
    • 一种热转印打印机,其包括根据期望的印刷图案产生热量的热敏头,具有用于支撑油墨纸和纸张的表面的压板,所述油墨纸和纸被热压头压在压板表面上,因此 来自油墨纸的油墨被转印到纸张上,用于存储和供给纸张的供纸件,用于存储和供应油墨纸的油墨供给和驱动器,驱动油墨纸的油墨供给和驱动 根据纸张的移动移动,布置在压板和纸供应器之间的纸驱动器,纸驱动器根据纸张相对于压板位置的位置将纸张驱动所需的长度,并且 纸张张力装置,用于至少在压板和纸张驱动器之间向纸张施加合适的张力,使得纸驱动器驱动纸张的长度与纸张在纸盘上移动的长度相同。 由于纸张在压纸板上移动的长度只相当于纸张驱动器驱动纸张的长度,纸张在纸盘上移动的长度可以通过纸张驱动器正确控制。

    • A magazine detachably installed in a main body of a disc changer is divided into sections by partitions for storing a large number of optical discs. The magazine is provided with a belt set around rollers, which carries the optical disc in contact with the belt. In the disc changer, the belt is rotated by a gear of the roller, which is engaged with an external drive gear for taking the optical disc through rotating movement. Among the optical discs which have been taken, a target optical disc opposite the slit of the disc control plate passes through the slit, and the other optical discs stop while abutting against the disc control plate. The optical disc which has passed through the slit is inserted into disc carriage rollers, and further carried to the drive for recording/reproducing.
