摘要:
A disk player has a disk cartridge for being loaded thereon, and accommodating a disk-type recording medium. The disk cartridge has a shutter arranged thereon, for performing slide-opening/closing in order to expose an information surface of the disk-type recording medium. The disk player is comprised of a carrier mechanism for carrying the disk cartridge to an information regenerating location and an information recording location, and a shutter sliding mechanism for slide-opening/closing the shutter. The shutter assumes an intermediate position of sliding when the disk cartridge is located at one of the information regenerating location and the information recording location, and assumes a terminal position of sliding when the shutter is located at the other one of the locations. The disk player also includes a. driving mechanism comprised of an engaging element and an engaged element which is separated from the engaging element when the information recording mechanism is not driven.

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.

A positioning system is provided for use in an information recording/reproducing apparatus for positioning a cartridge containing an information recording medium on a chassis mounting information recording and reproducing structure. Such positioning system comprises positioning holes formed on the cartridge containing an information recording medium; and positioning pins formed on the chassis mounting information recording and reading structure. In particular, when a cartridge containing an information recording medium is inserted into the recording/reproducing apparatus, one of the positioning pins is caused to insert into a corresponding positioning hole earlier than the insertion of other pin(s) into other corresponding positioning hole(s).

A semiconductor integrated circuit device has power source lines capable of supplying sufficient power to a cell string area without increasing the area of the device. The device has an I/O cell area arranged at the periphery of the device, to transmit and receive signals to and from the outside of the device. The cell string area contains cell strings each made of a sequence of logic gate cells and connected to the power source lines extending from the I/O cell area. The device further has a macro block between the I/O cell area and the cell string area, to provide at least one function. The power source lines extend from part of the I/O cell area, which is opposite to the cell string area across the macro block, to the cell string area by passing over the macro block. An insulation layer is formed between the macro block and the power source lines, to electrically isolate the macro block from the power source lines.

A cartridge of write and read type or a cartridge of read only type is selectively loaded to a recording and reproducing apparatus. The recording and reproducing apparatus is provided with: a magnetic head for applying a magnetic field; a head movement device for moving the magnetic head between a near position and a far position; a switching lever, which is movable between a non-regulating position to allow the magnetic head to move between the near position and the far position, and a regulating position to regulate the position of the magnetic head at the far position; and a slide plate disposed movably on a cartridge holder and having a protruded portion which is opposed to the cartridge stored in the cartridge holder. The protruded portion abuts to the loaded cartridge to move the slide plate, and the switching lever is positioned at the non-regulating position by abutting to the moved slide plate if the loaded cartridge is the write and read type. The protruded portion is engaged with a judgement recess of the cartridge, and the switching lever is positioned at the regulating position if the loaded cartridge is the read only type.

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. Finally, in the machining step, the finishing process is performed, while the robot (11) is controlled, based on the corrected teaching data.

A disc device includes. a case having an opening; and a tray that is movable to and retractable from the case and is provided on one surface thereof with an arc recess capable of holding an optical disc. The tray includes a cutout portion that is provided near a rear face of the arc recess and guides an inserted distal end of the optical disc toward a bottom side of the tray lower than an upper face of the arc recess.

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.
