  • Patent number: 8229594
    Abstract: This method controls an automatic finishing machine using a robot with a tool through a model storage step, a data acquisition step, a calculation step, an error derivation step, a correction step and a machining step. In the model storage step, shape data of an unfinished work or data of a three-dimensional model is stored in a memory. In the data acquisition step, the tool is brought into contact with the unfinished work W, thereby obtaining measurement data. Then, in the calculation step, actual-position data on a comparative object point is calculated based on the measurement data. Subsequently, in the error derivation step, a data difference between the calculated actual-position data and position data on the comparative object point in the three-dimensional model is obtained. Thereafter, in the correction step, teaching data indicative of the position of the tool corresponding to the shape data of the three-dimensional model is corrected, based on the data difference.

  • Publication number: 20090235287
    Abstract: A disc unit includes a push arm for providing a predetermined clearance between a periphery of a large-diameter disc and a guide lever used for guiding insertion and ejection of the large-diameter disc. The clearance is formed by moving the guide lever toward a left wall when the large-diameter disc is clamped on a turntable. With this arrangement, when the large-diameter disc is mounted on the turntable, the rotation of the large-diameter disc is not hindered.

  • Publication number: 20090133043
    Abstract: A disc unit includes: a slide stopper adapted to switch a state of the unit between an initial state, a guide-restricted state and a movement-unrestricted state by sliding in right or left direction; and a first plate spring and a second plate spring for biasing the slide stopper in the guide-restricted state or the movement-unrestricted state in a direction to return to an initial position. With this arrangement, the slide stopper can be constantly returned to the initial position unless in the guide-restricted state and the movement-restricted state. Thus, with a simplified arrangement, the disc unit can be switched between the initial state, the guide-restricted state and the movement-unrestricted state.

  • Patent number: 7519978
    Abstract: On the inner surface of a guide rail (411) having a concave groove, which extends in the vertical direction along a motion path of a disc drive (200) moved by a mover unit (300), a biasing cam (412) having thickened swelling parts (412a) at both ends is so provided as to have the groove width narrowed at both the upper and lower ends. A plate spring (420) which is pressed into contact with a guide surface of the surface of the biasing cam (412) by elastic biasing force is attached integrally to the disc drive (200). At the home position where the disc drive (200) operates and at the position where the disc drive (200) is lifted up, the plate spring (420) is strongly pressed into contact by the swelling parts (412a), and the disc drive (200) can be prevented from being moved by impact or the like from outside during operation. While moving, the pressing force is weakened so that load applied by the mover unit (300) can be reduced.

  • Patent number: 7302872
    Abstract: At least one shift gate includes a stabilizing range for stabilizing an engagement between the engaging portion and the at least one shift gate. The system stops movement of the movable member by driving the actuator and determines a portion at the movable member as a shift gate reference position at a time when the movement of the movable member stops. The system moves the movable member by driving the actuator, stabilizes the engaging portion in the stabilizing range, and determines the stabilizing position of the engaging portion as a position of the at least one shift gate.

  • Publication number: 20050188385
    Abstract: A disc drive (200), which has a disc tray (210) that carries an optical disc (10) and can be moved back and forth, is adapted to be moved out of and back into a case body (110) through an opening (111) by a mover unit. When the disc drive (200) is being moved, the drive operation of the spindle motor of the disc drive (200) is suspended to prevent the optical disc from rotating. The disc drive (200) is allowed to read information from and/or record information on the optical disc (10) only at the home position where it is housed in the case body (110) through the opening (111). Thus, the disc drive (200) is prevented from damaging the optical disc and other components by impact when it is being moved.
