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′).
摘要翻译： 前挡板（13'）包括形成在门构件（131）的上侧的两端的臂部（132,133）。 虽然一个轴部（136）通过定位部（134）形成在一个臂部（132）上，另一个轴部（137）形成在另一个臂部（133）上。 轴部分（136,137'）分别插入形成在切割和凸起部件（111）和侧壁（112）上的孔中。 切片（111）和侧壁（112）可旋转地支撑轴部（136,137'）。 由于臂部（133）和侧壁（112）之间没有定位部分，臂部（133）和侧壁（112）之间的间隙较宽。 快门弹簧（14'）不仅在关闭方向上向前挡板（13'）施加力，而且还将前挡板朝向切割和升高件（111）按压，以防止挡板沿着由 轴部分（136,137'）。

摘要： In a thin floppy disk drive comprises a disk shutter arm (26), rotatably mounted on a disk holder (22), for opening and closing a shutter (43) of a floppy disk (40) and an eject lever (25), rotatably mounted on a main frame (13), having an eject stop part (253) engaged with a plate stopper portion (212) of an eject plate (21), the eject lever (25) has an eject protrusion (252a). The disk shutter arm (26) has a shutter hook part (261a) engaged with the eject protrusion so as to control a rotation operation of the eject lever when the floppy disk (40) is not inserted in the thin floppy disk drive. It is therefore possible to prevent the elect lever (25) from rotating over a predetermined rotation angle as far as the floppy disk (40) is not inserted in the thin floppy disk drive.

摘要： A flexible disk drive includes a case and a disk holder provided in the case. A flexible disk is mounted on the disk holder. A part of the disk holder abuts against an inner face of the case. Preferably, the part of the disk holder is a tip end portion of the disk holder. The tip end portion of the disk holder is bent in a slanted direction so as to enlarge an inlet of the disk holder for the flexible disk to be inserted.

摘要： A cam plate member 24 is provided such that it is supported by a lower chassis 8 so as to rotate freely and rotates in accordance with the inserting/ejecting operation of a disk cartridge 5. The cam plate member 24 includes an elastic cam lever portion 24f and a cam convex portion 24g which are formed integrally. The elastic cam lever portion serves to push up the disk cartridge thereby to prevent hitting between the disk cartridge and a magnetic head 6 until the disk cartridge 5 that is inserted is loaded to a recording/reproducing portion 17 after the state where the disk cartridge moves onto a guide convex portion 14 formed at the lower chassis 8. The cam convex portion serves to push up and hold a portion 28 of a holder 10 which holds and loads the disk cartridge 5 from a portion 4 of the recording/reproducing portion 17 thereby to prevent the cartridge holder from being bent due to vibration.

摘要： In a flexible disk drive for a flexible disk, a main frame defines a receiving portion for receiving the flexible disk. The main frame has a principal surface which faces the receiving portion and extends in a first direction and a second direction perpendicular to the first direction. A carriage assembly is mounted on the main frame and has a magnetic head for accessing the flexible disk. The carriage assembly is movable to carry the magnetic head along the principal surface. An eject base is coupled to the main frame and has a main portion facing the principal surface and side plates opposite to each other in the first direction. Between the main frame and the eject base, an eject plate is placed movable in the second direction for ejecting the flexible disk from the receiving portion. The eject plate has side plates facing the side plates of the eject base in the first direction, respectively. A guiding mechanism is coupled to the side plates of the eject base and to the side plates of the eject plate and guides movement of the eject plate in the second direction.
