摘要： In a magnetic disk driver for driving a magnetic disk inserted thereinto, a pair of locating members locates both ends of a guide bar to mount the guide bar on a main surface of a main frame in cooperation with a guide bar cramp. Disposed in the vicinity of a magnetic head, one of the locating members includes a projecting portion which projects on the main surface of the main frame. The projecting portion may be a projection squeezed out of the main frame by half blanking. Disposed over the main surface of the main frame and apart from the main frame, a head carriage holds a magnetic head movably along a predetermined radial direction to the magnetic disk. The head carriage comprises a head carriage body and a supporting frame for supporting the head carriage body. The supporting frame projects into the main surface of the main frame and is fitted on the guide bar. The main frame comprises a safe portion, which is opposed to the guide bar, for preventing contact of the supporting frame of the head carriage with the main surface of the main frame when the head carriage slides along the guide bar. The safe portion includes a concave portion. The concave portion may be dented by half blanking.

摘要： A disk holder table has a bottom surface to which a holder ring for holding a drive roller is assembled. The holder ring is made of metal and has a generally rectangular shape. The holder ring is engaged by hooks formed on the bottom surface of the disk holder table. The disk holder table has guide portions formed on the bottom surface thereof to restrict the range of rotation of the holder ring in parallel to the bottom surface. The holder ring is urged in a predetermined direction by a rod spring formed on the bottom surface.

摘要： In a disk drive having a frame unit (63) in which a rear wall (81) is integrally formed with a bottom plate (63a) by press work such as bending, punching or the like, opening portions (53, 55, 57, 59) are inevitably formed as a designing requirement to form fixing members for fixing a circuit board or to prevent contact owing to the retreat of a carriage assembly (67) at the time of punching or press work of the rear wall (81) of the frame unit (63). To provide a disk drive having high reliability by preventing dust from entering into the disk drive from the opening portions (53, 55, 57, 59) and by preventing destruction of data on a disk owing to pressing of dust onto the disk by a recording and reproducing head, rear cover (83) is mounted on the rear wall (81) for closing the opening portions (53, 55, 57, 59).

摘要： A floppy disk drive includes a frame having a bottom portion and left and right walls and a casing for covering the frame. The casing includes an upper cover for covering an upper side of the frame and a lower cover for covering a lower side of the frame, in which the upper cover has a top plate and left and right side plates, and the lower cover has a bottom plate and left and right plates. Each of the side walls of the frame is designed so as to have size and height that are partially overlapped with the side plate of the upper cover and the side plate of the lower cover, respectively, at each side of the casing, thereby providing a triplex structure for reinforcing each side of the casing.

摘要： A front shutter (13′) comprises arm portions (132, 133) formed at both ends of an upper side of a door member (131). While one shaft portion (136) is formed on one of the arm portions (132) through a positioning portion (134), the other shaft portion (137) is formed on the other of the arm portions (133). The shaft portions (136, 137′) are inserted into holes formed on a cut and raised piece (111) and a side wall (112) respectively. The cut and raised piece (111) and the side wall (112) rotatably supports the shaft portions (136, 137′). A gap between the arm portion (133) and the side wall (112) is wider because of no positioning portion between the arm portion (133) and the side wall (112). The shutter spring (14′) not only gives force to the front shutter (13′) in a closing direction but also presses the front shutter toward the cut and raised piece (111) to prevent the shutter from moving along a pivot defined by the shaft portions (136, 137′).
