PURPOSE:To form an image on a predetermined position of a paper by printing or copying in such a manner that the position of the head of the conveyed paper comes to a feed completing position assuredly CONSTITUTION:A paper fed to a paper feed cassette is conveyed to a reference position A sending quantity of the paper to a paper feed completing position after the head of the paper is detected by a paper detecting sensor is decided based on a length conveyed from the reference position to a position where the head of the paper is detected by the paper detecting sensor

Paper feeding device

Provided is a machine tool which is equipped with a floating mechanism, and the whole of which can be miniaturized and lightened, said floating mechanism being equipped with carriers of loads generated in both radial and thrust directions, resulting in deformation of the floating mechanism being reduced. The floating section (4) of the machine tool is provided with a hollow circular-plate-shaped inner ring (9) comprising an outer peripheral surface section (9a), an upper surface section (9b), and a bottom surface section (9c); and an outer ring (8) comprising an inner peripheral section (8a) and an inner ring receiving section (8b). The outer ring (8) is fixed to a robot arm. The inner ring (9) is fixed to a tool driving section. Furthermore, the outer peripheral surface of the inner ring (9) is formed by a spherical surface which is equidistant from the center point (14) of a hollow circular plate．The hollow circular-plate-shaped inner ring (9) is pressed down by a hollow piston.

The tubing segment is designed adjacent to a transverse gallery for on-directional drilling of drilling rods, and has an inverse cassette in which an inner panel (2) is arranged. The inner panel is arranged at stiffening sheets (3) inside a tunnel. An outer panel is provided for replacement of a tubing element. The inverse cassette is designed to be larger than the adjacent normal cassettes. The tubing segment is made of steel.
