A sheet holder removably attached to a hopper of a image reading apparatus. The sheet holder has a front bottom wall, a rear top wall, and an intermediate wall connecting the front bottom wall to the rear top wall. The front bottom wall provides a sheet placing area onto which small and thick sheets like business cards are placed and a holding member holds the sheets on the sheet placing area. A pick roller of the image reading apparatus can contact the sheet on the sheet placing area when the sheet holder is attached to the apparatus. The apparatus has a box-shaped a casing having a drawable hopper table providing a hopper for placing normal thin sheets thereon.

In a three-wavelength-compliant optical disk apparatus, the present invention enables to shorten time required for starting the apparatus such as discrimination of an optical disk and adjustment of a beam-expander. At the time of starting the apparatus, the operation of a tray driver which pulls a loaded optical disk within the apparatus is conducted in parallel with the operation of a beam-expander driver which allows a movable lens of the beam-expander to move to a predetermined position in accordance with the kind of optical disk. Further, at the time of discriminating the disk, the number of times an optical disk of a specific kind has continuously been loaded into the apparatus to date is stored in a memory, and a sequence of discriminating the kind of optical disk that is newly discriminated is switched by referring to the history information.
摘要:
Within an optical disk recording/reproducing apparatus, in which a beam spot is irradiated upon an optical disk loaded therein, to obtain a reflection light obtainable therewith, and thereby conducting recording or reproducing of information upon an information recording surface of the optical disk, a microcomputer (μ-computer) 9 for controlling the operation of the apparatus executes a predetermined process by considering the optical disk loaded into the apparatus to be an optical disk, which is loaded previously, executes a retry process when determined that the optical disk loaded into the apparatus is not the optical disk loaded into the apparatus previously, as a result of the process mentioned above, executes a process for recognizing kind of the optical disk inserted, and memorizes information of the kind of the optical disk inserted into said apparatus, which is obtained in the recognizing process mentioned above, thereby shortening the startup time of the apparatus, as a whole thereof.
摘要:
Within an optical disk apparatus for recording or reproducing information onto/from an optical disk 1, by irradiating one three (3) laser beams upon information recording surface RS thereof, each having wavelength different from each other, selectively, through a 3-wavelengths compatible objective lens 31, according to a method for discriminating a kind of optical disk loaded therein, focus sweep is conducted upon the optical disk loaded, in a descending order of distance between the position of the objective lens when it focus the laser beam upon the information recording surface and the disk surface DS, so as to detect a time between the disk surface DS and the information recording surface RS on the optical disk, from a reflection light obtained, and thereby discriminating the kind of the optical disk upon basis of the time between the reflections detected in the above.

A levitation system of a magnetically levitated train is provided wherein superconducting magnets are installed in a car body, and the first layer and the second layer of levitation coils are so arranged as to be in a shifted location relative to each other in the moving direction of the train. By making the levitation coils two layers and by arranging the two layers in the shifted location relative to each other in the moving direction, amplitude of higher harmonic waves is reduced to a very small level, substantially to zero.

A method of relieving residual stress in a metal pipe comprises the steps of applying, by using a pressure medium, a low pressure to an interior of the metal pipe placed in dies, and applying, while preventing the buckling, an axial compression load to the pipe so as to effect a uniform plastic deformation of the entire metal pipe while maintaining the desired shape of the pipe, thereby relieving the residual stress in the metal pipe.
