摘要： A disk drive motor (5) for driving and rotating a recording medium (disk), a head (57) for recording or playing back information to/from this disk, and a head drive mechanism for driving the head, are disposed inside a case body (15, 16) of the magnetic recording unit. A lid body (17) to close the cartridge insertion slot (18) is disposed the case body (15, 16) at a position facing the cartridge insertion slot (18). When the lid body (17) falls down the front side and the cartridge insertion slot (18) is opened, the top face of the lid body (17) becomes substantially on the same plane as the top face of the frame plate where the disk drive motor (5) and the head (17) drive mechanism are mounted.

摘要： A disk drive device (1) comprises a body chassis (2) and a tray (3) movable relative to the body chassis (2). The body chassis (2) is provided with a stage (6) at one side thereof, which is higher than the central bottom face. On the other hand, a part of the disk protective portion (11) of the tray (3), which overlaps the stage (6), is cut out at its rear end (20a) in an arc shape. As a result, the disk protective portion (11) covers the whole area of a disk (14) and, at the same time, forms a large space between it and the front end (6a) of the stage (6).

摘要： Tilt adjustment for a guide member with respect to a rotational reference surface of a rotary table is made on the basis of an external reference in which an inner peripheral side end of a disc is vertically adjusted by setting an outer peripheral side end as a reference. A given vertical fluctuation amount range of the outer periphery of the disc in rotation and a necessary tilt adjustment amount range for the adjustment of the tilt of an optical axis associated with a head are made to overlap each other. The uppermost end position of the head is situated within the given fluctuation amount of the outer periphery of the disc-shaped recording medium below the rotational reference surface of the disc rotary table.

摘要： In a card-type magnetic recording device (1), a motor (10) for driving a magnetic disk stored therein is mounted in a recess (9) that is formed in a frame plate (8). In order to form the recess (9) in the frame plate (8), backward extrusion molding is effected by means of a die (35) having a slope (39) and a punch (37) having a slope (40). A region between the slope (39) and the slope (40) is crushed by means of the die (35) and the punch (37) that relatively move up and down, and extends backward as well as forward with respect to the moving direction of the punch.

摘要： A data storage device has a disk-drive motor, a head-drive motor, read/write heads, and an integrated circuit board, all mounted on a single-piece integral frame and enclosed by a casing. Each motor is mounted within a surface recess on the frame via an attachment lip integrally formed into each recess. Additionally, a bend is formed across the width of the frame. The single-piece frame, frame bend, and surface recesses provide the data storage device with significant structural rigidity and thus enhance the ability of the device to withstand the application of externally-applied forces.

摘要： A shutter locking mechanism for a FDD capable of securely keeping the shutter in opened state against any external impact. This mechanism comprises a pivot secured to the carrier for axially and rotatably supporting the shutter opening lever, and a projecting portion formed at the distal end of the shutter opening lever and fit to an aperture existing at the shutter opening lever contact side of the shutter in the loading position. The projecting portion enters the aperture at the right corner of the shutter in the loaded position while at the left corner claw portions of the stopper hold the shutter for preventing the distal end of the shutter opening lever from separating from the shutter.

摘要： A guide member (20) is disposed between a body chassis (2) of a disk driving apparatus (1) and an electric connection wire (15). The guide member (20) moves together with a tray (3) to prevent the body chassis (2) and the electric connection wire (15) from coming into contact with each other and moving. In a state in which the tray (3) is sufficiently pulled out from the body chassis (2), the guide member (20) projects from the tray (3) to prevent the electric connection wire (15) from coming into contact with the body chassis (2).

摘要： In a disc drive unit, a notch or opening is provided in a part of a lower case body, out of upper and lower case bodies containing therein a functional member, such as a spindle motor, whereby a part of the functional member, of which the vertical dimension cannot be reduced with ease, is exposed. Thus, a clearance dimension that is required when there are no holes, as well as the thickness dimension of the lower case body, is supposed to be a part of the vertical dimension that the functional member can utilize, whereby the overall vertical dimension of the unit is reduced without lowering the performance of the functional member.

摘要： A card-type electronic device comprises a casing (4) composed of a rectangular frame (5) and two covers (6, 7) individually covering the upper and lower surfaces of the frame (5). Substantially U-shaped retaining pieces (11a, 11b) are formed by bending tongues (10), which partially protrude from the long side edge portions of the covers (6, 7), so that their distal ends are directed toward the other covers (6, 7) and further bending the distal ends on the inner peripheral side. On the other hand, the side faces of the frame (5) are formed with recesses (19a, 19b) for vertically guiding the retaining pieces (11a, 11b) and retaining portions (20a, 20b) adapted individually to engage the retaining pieces (11a, 11b) fitted in the recesses when the retaining pieces slide in the longitudinal direction of the casing (4).
