Travel devices for a transport vehicle are arranged in a longitudinal direction and a width direction of a loading platform to allow traveling of the loading platform. In this travel device, an arm includes an upper end turnably supported at a lower portion of the loading platform. The arm includes a lower end where an axle box is supported swingably in up and down directions. A wheel has a mid-plane that intersects with a swing plane of an axle shaft disposed at the axle box, and is supported at the axle shaft. Accordingly, this ensures a small vehicle width L2 of the transport vehicle.

In an oscillating apparatus, a detection unit detects a frequency offset between an input signal and a reference signal. A code generation unit specifies a relationship among a code having a predetermined number of bits, the frequency offset, and a voltage to be applied to a voltage-controlled oscillator by a DAC, in accordance with a frequency offset detection state of the detection unit. The code generation unit also generates a frequency offset correction code having a predetermined number of bits in accordance with the specified relationship. The DAC applies the voltage to the voltage-controlled oscillator, in accordance with the relationship described above and the code generated by the code generation unit. The voltage controlled oscillator outputs an oscillator signal having an oscillation frequency corresponding to the voltage applied by the DAC.

A memory device for recording, playback, and erasure of data through the application of an optical head along a memory medium includes a head carriage and a carriage lock. The head carriage moves the optical head along the surface of the memory medium, and the carriage lock prevents movement of the head carriage in response to a specific shock force. The carriage lock utilizes mechanical energy received from the shock force itself to prevent the movement of the head carriage.

An oscillating circuit includes an oscillating transistor in which the collector or the base is grounded in a high-frequency manner, and a bias resistor connects the emitter of the oscillating transistor to a ground in a direct-current manner. In the oscillating circuit, a resonance unit, having maximum impedance at the oscillation frequency, is interposed between the bias resistor and the ground. Thus, an oscillation signal is obtained from the connection point between the bias resistor and the resonance unit.

An optical information storage apparatus incorporates a medium storage section that stores multiple optical storage media. An information reproducing section individually reproduces information from the optical storage media, and a medium moving section moves the optical storage medium between the medium storage section and the information reproducing section. A cleaning section is placed on a path along which the moving section moves the optical storage media. The cleaning section removes unwanted matter from the optical storage media as they are moved from the medium storage section to the information reproducing section. This prevents unwanted matter from entering the information reproducing section.

Magnets for seeking provided for the base and magnets for focusing provided for a carriage are so arranged that they are shifted perpendicularly relative to each other. With this arrangement, since the attractive force or the repulsive force, which includes a perpendicular element, is generated between the magnets for seeking and the magnets for focusing, the urging force to the carriage against guide rails can be adjusted.
