  • Publication number: 20090190972
    Abstract: A belt drive control unit controls a rotation of belt supported by first and second rollers. Each of rotations of the first and second rollers are detected as first and second results. A rotation of the first roller is controlled in connection with thickness fluctuation in the belt using the first and second results. The belt drive control unit includes a sampling data acquisition unit, a correction value generator, a correction value storage, and a correction value reading controller. The sampling data acquisition unit obtains sampling data by sampling a difference value between the first and second results. The correction value generator generates correction value data for the belt based on the sampling data. The correction value storage stores the correction value data. The correction value reading controller reads the correction value data based on a rotation number of the belt to control a rotation of the first roller.

  • Publication number: 20090017953
    Abstract: A rotary drive device includes a motor including a rotary shaft, a planetary gear mechanism, and a rotation position detector. The planetary gear mechanism decelerates a rotation output of the motor at a reference reduction ratio and includes an outer gear, multistage gears, and an output shaft. The outer gear is fixed to a housing of the motor. The multistage gears are provided inside the outer gear. The output shaft transmits the decelerated rotation output of the motor to an outside of the rotary drive device. The rotation position detector detects a rotation position of the output shaft to control rotation of the motor. The motor, the planetary gear mechanism, and the rotation position detector are combined into a single integrated unit and aligned in an axial direction of the rotary shaft of the motor.

    Abstract: The invention provides a liquid crystal device including: a pair of substrates; a liquid crystal layer having a negative dielectric anisotropy; a pixel electrode; a counter electrode, the counter electrode being opposed to the pixel electrode; a vertical alignment film that aligns liquid crystal molecules of the liquid crystal layer in a direction in which the long axes of the liquid crystal molecules are oriented perpendicular to the pair of substrates. The pixel electrode is made up of island-pattern sub pixel elements each two adjacent ones of which are connected to each other via a connection portion having a width narrower than that of the sub pixel element. In addition, the light shielding film is formed, on one of the pair of substrates, in each region not corresponding to the connection portion between each two of the sub pixel elements that are adjacent to each other.

  • Publication number: 20080211176
    Abstract: A common driving source transmits a drive force to a driving unit that drives a feeding unit and a conveying unit. The driving source is a motor that rotates in either of a normal direction and a reverse direction. The feeding unit includes a mechanical drive-blocking mechanism in its driving sequence. The conveying unit includes a two-system driving sequence and a mechanical drive-blocking mechanism in the driving sequence so as to rotate in one direction regardless of a rotating direction of the driving source. A reduction ratio of each driving sequence in the conveying unit is identical.

  • Publication number: 20060238481
    Abstract: In an LCD device, a driver circuit board for outputting signals to source driver ICs and gate driver ICs is placed at a position on a cover panel distant from a position on the cover panel at which an inverter control board for cathode ray tubes is placed. The driver board is connected by first FFCs to a source bus board having the source ICs mounted thereon, and is further connected by a second FFC to a gate bus board having the gate ICs mounted thereon. The second FFC extends via a ridgeline formed between a top surface and a side surface of a liquid crystal panel. The signals from the driver board to the gate ICs are provided via the first FFCs, the source board, the second FFC and the gate board. This LCD device has improved layout flexibility and facilitates a change of placement of e.g. a backlight.
