A method for detecting a size of an optical disk loaded in an optical disk drive is disclosed. The optical disk drive has an optical pickup head, and the initial position of the optical pickup head is located on the outer side of a track. The steps of the method are described as follows. First, the optical disk is loaded. Then, the optical pickup head is moved from the initial position to a first position, and a laser beam is irradiated simultaneously. The laser beam reflected by the optical disk is received by the optical pickup head. According to the condition of the reflected laser beam received by the optical pickup head, the size of the disk can be determined.

Method for detecting size of the optical disk and ejecting optical disk

A sheet-by-sheet paper feeding structure includes a sheets separating plate and a pressure plate. When a pile of paper is fed into the paper feeding structure, a front end of the pile urges against the sheets separating plate, which is in turn pressed by a press leg of the press plate above so that the sheets of paper are checked from displacing forwardly. The press plate further includes elastic plates having elastic plate press legs that help keep the sheets of paper flat and stable during feeding. A lowermost sheet of the pile is in direct contact with a roller of a facsimile machine or printer or the like. When the roller rolls forwardly, it will only bring the lowermost sheet to advance forwardly while the rest of the pile is being checked by the sheets separating plate.
