摘要： PURPOSE:To prevent a tape from being wound irregularly or traveling unstably by performing feedback control over a tape-width directional moving device according to the quantity of displacement of the tape if a sensor detects the width directional position shift of the tape when the tape is sent out or taken up. CONSTITUTION:When the tape 56 is wound irregularly around a reel 55, the tape 56 shifts in position on a back tension post 57. In this case, the post 57 is irradiated with specific light centering on the reference travel position of the tape 56 and its reflected light is detected by a photodetecting element 64. The specularly finished white post 57 differs in reflection factor from the black tape 56, so the tape displacement is measured as variation in the quantity of reflected light from the post surface. Namely, when a detected distance is constant, the quantity of reflected light from the post 57 is reduced and the detected quantity decreases as the tape edge moves down from the reference travel position. Then when the post 57 stops while abutting on a stopper 60, the tape 56 is held at a constant distance to the sensor 61. Then a reel turntable 9 is moved so that the width directional displacement of the tape 56 is eliminated.

摘要： PURPOSE:To surely and easily control the shift of a tape in its width direction by moving two rotors which hold the running tape between them and revolve in the tape width direction in accordance with a sensor which detects the tape width direction. CONSTITUTION:A running tape 5 is held between a revolving guide roller 1 and a pinch roller 2. Then a sensor 3 detects the position of the tape 5 in its width direction, and the roller 2 is moved in the tape width direction by the detection output of the sensor 3. At the same time, the roller 1 also moves after the roller 2. Thus one of both rotors is pressed to the other and at the same time these rotors are supported so that they can move in the tape width direction. Then the shift of the tape 5 can be surely and easily controlled in its width direction with no sliding of the tape 5 on a post.

摘要： PURPOSE:To stabilize the traveling of a tape by making a supply reel base movable in the axial direction, providing a sensor for detecting a tape position in its widthwise direction in the vicinity of a tape traveling positioning post and correcting the position of a supply reel in its vertical direction. CONSTITUTION:The supply reel base 65 for rotating the supply reel 55 is made movable in rotation and also in the axial direction. And, with regard to the tape traveling positioning posts, one of the posts from the supply reel 55 to the 2nd one is assigned to be a rotary post 57. Furthermore, the sensor 61 for detecting the position of the tape 56 in the widthwise direction is provided in the vicinity of the position of the rotary post 57, and the widthwise position of the tape 56 to be fed is detected by an output of the sensor 61. Thus, at the time of feeding the tape, a variation in the tape widthwise position is detected, and by moving the reel base under rotation in the axial direction in accordance with this variation, the traveling of the tape can be stabilized.

摘要： PURPOSE:To improve a measuring accuracy by detecting the position in the width direction of the tape wound on a tape drawing post with the variation in the received light quantity of a light receiving sensor and keeping the distance between the sensor and post constant. CONSTITUTION:A back tension post 5 draws a tape 27 out of a cassette 1 so as to press the nonmagnetic face of the tape 7 by the revolving centering around the shaft 31 of a post support block 32. It is then moved until abutting to a stopper 30. When it is stopped in the state of its abutment on the stopper 30, the back tension post and tape 27 wound thereon are held in a constant distance to a sensor 21. A specific light is then radiated on the post 5 with the reference traveling position of the tape 27 as the center and the reflected light is detected on a photodetector 23. Due to the reflectivity differing with a specular finishing white post and black tape 27, the tape displacement is measured as the variation in the reflection light quantities of the post face.

摘要： PURPOSE:To control the running position of a tape in its width direction by providing a means which moves a tape guide in the tape width direction via a sensor which detects the position of the tape in its width direction and connecting these parts in one body at the tape running position. CONSTITUTION:A tape guide 5 is supported by a slider 4 so as to move up and down, and the position of a running tape 3 is detected by a sensor 38 in the tape width direction. Then a tape width direction shift means 12 is provided at a position near a stopper 10. Then a connection means 13 connects the guide 5 and the means 12 together in one body when the slider 4 is controlled by the stopper 10 in terms of its position. In such a constitution, the means 12 is controlled by the sensor 38 and then the tape 39 is controlled at a constant height by the guide 5.

摘要： PURPOSE:To prevent a random winding of tape by moving a reel base in the axial direction so that inclination and displacement are not caused on a tape between two sensors in accordance with the displacement of a tape when the positional fluctuation in the width direction of the tape is detected at the winding time. CONSTITUTION:It is detected as to whether a tape 56 comes in while descending to a reel 55 or comes in while ascending is detected from the outputs of sensors 60, 61 and a reel base device 65 is controlled so that the tape 56 is wound in parallel to the reel 55 in the case of its being in descending or ascending tendency. Namely, in the case of its coming in while descending, the reel 55 is lifted by the quantity corresponding to the inclination thereof with the electrification to the driving coil 35 of a voice coil motor 68, also in the case of its coming in while ascending to the reel 55, the reel 55 is descended by the quantity corresponding to the inclination by the voice coil motor 68 and the tape 56 is made to be wound in parallel at all times and also by passing through a reference traveling position.

摘要： PROBLEM TO BE SOLVED: To make it possible through a simple structure to secure easily and appropriately a lubricant fluid pouring volume and implement effectively and successfully a pouring process of the lubricant fluid and removing processes thereof. SOLUTION: An outer peripheral wall surface of a dynamic pressure bearing member 13 is formed in such a shape that an outside dimension decreases in a direction away from a fluid seal portion 24 to an axial direction. There is provided an edge portion 13d defining a surface bending discontinuously along the axial direction of the outer peripheral wall surface of the dynamic pressure bearing member 13 and thereby an opening portion of the fluid seal portion 24 is made visible along the outer peripheral wall surface of the dynamic pressure bearing member 13. A whole pouring lubricant fluid volume containing the fluid seal portion 24 including a thrust dynamic pressure bearing portion SB can be easily checked, and redundant lubricant fluid adhered to the outer peripheral wall surface of the dynamic pressure bearing member 13 is prevented from flowing into the fluid seal portion 24 by the shape effect of the edge portion 13d.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily and correctly laser-weld a fitting boundary part F, where a rotary body 6 and a rotary axis 2 are fitted to each other. SOLUTION: A plurality of positions on a fitting boundary part F, which are positioned approximately at equal intervals, are simultaneously welded with laser beams L1, L2 having approximately equal power. Thereby, deformation action at each welding position is compensated so that such a deformation as a rotary axis 2 is tilted to one direction is well prevented. Using a pair of beams, which are branched from an irradiating beam from a single beam source through an optical system as a plurality of the laser beams L1, L2, the powers of the laser beams at each welding part are made equal. Besides, the mutual positional relation of the laser beam L1, L2 is kept constant.
