摘要： The thickness of a disk device is determined by the sum of the thickness of a cartridge, the thickness of a space, formed as a result of movement of the cartridge, the thickness of a mechanism chassis and the thickness of a vibration-insulating space, and therefore it is difficult to achieve the thin design of the disk device. When the cartridge is to be loaded into a predetermined position, the cartridge is moved toward the mechanism chassis while the mechanism chassis is moved toward the cartridge, thereby providing vibration-insulating spaces, and with this construction, there can be provided the disk device of a thin design.
摘要翻译：盘装置的厚度由筒的厚度，由盒的移动形成的空间的厚度，机构底盘的厚度和隔振空间的厚度之和决定，因此难以实现盘装置的薄型化设计。当盒被装载到预定位置时，盒机构朝向机架底座移动，同时机架底盘向盒移动，从而提供隔振空间，并且通过这种结构，可以提供盘装置薄的设计。

摘要： A front shutter (13null) 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, 137null) 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, 137null). 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 (14null) not only gives force to the front shutter (13null) 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, 137null).
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 high-density flexible disk drive, a color of at least a surface of a cover (22) (in addition, a color of at least a surface of an eject button (30)) is different from that of at least a surface of a body of a front panel (20). A user can visually distinguish the high-density flexible disk drive from a normal-density dedicated flexible disk drive in which a color of a surface of a cover is identical with that of a surface of a body of a front panel. Thus, a large-capacity flexible disk can be correctly inserted into the high-density flexible disk drive without being erroneously inserted into the normal-density dedicated flexible disk drive.

摘要： In a floppy disk drive having a main frame in which a floppy disk is inserted and a DD motor for rotatably driving the floppy disk inserted in the main frame, the floppy disk drive has a motor frame for mounting the DD motor thereon that is constituted by one piece integrated by the main frame. Preferably, the motor frame part may have a drawn-shape obtained by drawing the main frame. In addition, the floppy disk drive has an electronic processing arrangement for a frequency generation pattern. The electronic processing arrangement gives play to a function equivalent to the frequency generation pattern required to control the DD motor.

摘要： A projecting portion is formed on an edge, which provides a notch for an eject button, of a front shutter of an FDD. The projecting portion projects toward the eject button. The eject button provides a cavity for canceling interference between the projecting portion and the eject button in a state without external force. Upon receiving external force, the eject button is pressed to the projecting portion. In this state, the front shutter is forced to rotate in a closing direction thereof. Because the front shutter keeps a closed state, the force given to the projecting portion has a direction parallel to a main surface of a door member of the front shutter. Therefore, the door member is not bent by the external force and the front shutter does not come off from a main frame of the FDD.
摘要翻译：突出部分形成在FDD的前快门上的为弹出按钮提供凹口的边缘上。突出部朝向弹出按钮突出。弹出按钮提供用于在没有外力的状态下消除突出部分和弹出按钮之间的干涉的空腔。当接收到外力时，弹出按钮被按压到突出部分。在这种状态下，前挡板被迫沿其关闭方向旋转。由于前挡板保持关闭状态，因此施加到突出部的力具有平行于前挡板的门构件的主表面的方向。因此，门构件不被外力弯曲，并且前挡板不从FDD的主框架脱落。

摘要： The present invention provides a cartridge accommodating a disk therein which is inserted into a cartridge holder, the cartridge holder being provided with a mis-insertion protection member. The mis-insertion protection member is located within an insertion path along which the cartridge is inserted into the cartridge holder. The cartridge has a substantially rectangular shape. The cartridge has a corner portion at each of four corners of the substantially rectangular shape, the corner portion being shaped so as to abut on the mis-insertion protection member to move the mis-insertion protection member out of the insertion path. The cartridge has at least two mis-insertion protection mechanisms for engaging with the mis-insertion protection member so as to prevent the cartridge from being mis-inserted. The cartridge has two side surfaces which are substantially perpendicular to a surface of the disk and extend along a direction substantially parallel to a direction in which the cartridge is inserted into the cartridge holder. A mis-insertion protection mechanism of the at least two mis-insertion protection mechanisms is provided on each of the side surfaces.
