摘要： An image recording method and apparatus employing a thermal head capable of making a sublimation type thermal transfer recording and a fusion type thermal transfer recording by means of the same thermal head. This apparatus sets its vertical printing pitch at different values in the sublimation type recording mode and the fusion type recording mode. In the sublimation type recording mode, after making a first printing, this apparatus feeds a recording paper by a distance which is an integral multiple of the vertical printing pitch and makes a second printing using the same printing data as the first printing. In the fusion type recording mode, after making a 1-line printing, this apparatus feeds the recording paper by a 1-line spacing and makes a printing by means of printing data of the next line.

摘要： A recording unit has an illuminating device for projecting light on an original to form an original image, and an optical device which focuses the original image formed by the illuminating device. A light control plate has a slit for allowing a portion of the original image focused by the optical device to pass through. The light which passes through the slit of the light control plate is guided onto a print head which ejects ink on a recording medium when exposed to the light.

摘要： A laser beam scanning device is comprised of a laser beam source for emitting a laser beam, a polygon mirror rotatable for reflecting the laser beam to deflect the same linearly in primary scanning direction and a main motor for rotating the polygon mirror. An optically converging system converges the laser beam reflected from the polygon mirror onto a photosensitive medium. A secondary scanning system includes a driving source having a pulse motor for shifting the laser beam relative to the photosensitive medium in secondary scanning direction substantially perpendicular to the primary scanning direction to thereby scan the laser beam two-dimensionally on the photosensitive medium. A controlling circuit produces a common clock signal for controlling and driving the main motor and the pulse motor according to the common clock signal.

摘要： A double sleeve type dynamic bearing comprises a fixed shaft having at least one end fixedly mountable to an apparatus in which the bearing is utilized, a rotary sleeve arranged coaxially with the fixed shaft so that a first fine gap is formed therebetween, a fixed sleeve arranged coaxially with the rotary sleeve so that a second fine gap is formed therebetween, and a lubrication oil filled in the fine gaps. The first fine gap and the second fine gap each have an open end exposed to air outside the bearing and an opposite end that is not exposed to the air, the opposite ends being in communication with each other. A holding member holds the fixed shaft and the fixed sleeve and is disposed adjacent to a lower end surface of the rotary sleeve to form a third fine gap between the holding member and the lower end surface of the rotary sleeve. The third fine gap is formed with a thrust dynamic pressure producing groove, and opposite ends of the first and second fine gaps meet each other through the third fine gap. A peripheral surface of at least one of the fixed shaft, the rotary sleeve and the fixed sleeve forming at least one of the first and second fine gaps has a dynamic pressure producing groove formed therein.
