摘要： A spindle motor has a rotor, a stator and a dynamic pressure bearing for supporting the rotor for rotation relative to the stator. The dynamic pressure bearing comprises a rotational shaft mounted for undergoing rotation and having a thrust bearing portion and a radial bearing portion. A bearing member rotatably supports the rotational shaft and has a closed end forming a small diameter cylinder portion for receiving the radial bearing portion of the rotational shaft and an open end forming a large diameter cylinder portion for receiving the thrust bearing portion of the rotational shaft such that first gaps for receiving a lubricating oil are formed between the rotational shaft and the bearing member. A thrust pressure member is connected to the bearing member to form a capillary seal between the rotational shaft and the open end of the bearing member and to form second gaps between the thrust pressure member and the rotational shaft for receiving a lubricating oil. An oil receiving groove is formed in at least one of the thrust pressure member and the rotational shaft for receiving a lubricating oil.

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： 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.
