摘要： In a reel hub releasing mechanism, a seesaw type release lever is arranged so as to be turnable with its central part as a fulcrum, and it includes first and second flat members extending onto both sides from the fulcrum. The first flat member has an engaging protrusion at its distal end, while the second flat member has at its distal end a lever manipulating protrusion which protrudes upwards in order to manipulate a lock lever. A tape cartridge is formed with a window for snugly inserting the lever manipulating protrusion. When the lever manipulating protrusion abuts against the lock lever through the window, the operation of releasing reel hub lock is effected, and the tape cartridge is positioned so that the position of the window in the direction of inserting the tape cartridge into the slot of a tape drive may become substantially equal to the position of the lever manipulating protrusion in the inserting direction. It is accordingly possible to provide that reel hub lock mechanism of the tape drive which can position the tape cartridge simultaneously with the release of the reel hub lock, without separately forming any positioning part, and the tape drive which comprises the reel hub lock mechanism.
摘要翻译：在卷盘释放机构中，跷跷板型释放杆配置成以其中心部为支点的方式旋转，并且其包括从支点延伸到两侧的第一和第二扁平构件。第一扁平构件在其远端处具有接合突起，而第二平坦构件在其远端处具有向上突出的操纵杆操纵突起，以便操纵锁定杆。带盒形成有用于紧密地插入杠杆操纵突起的窗口。当杠杆操纵突起通过窗口抵靠锁定杆时，释放卷盘毂锁的操作被实现，并且带盒被定位成使得窗口在将带盒插入到槽的方向上的位置带驱动器可以变得基本上等于杠杆操纵突起在插入方向上的位置。因此，可以提供带驱动器的卷轴毂锁定机构，其可以在不分开形成任何定位部件的同时释放带盘毂锁，并且包括卷轴毂锁定机构的带驱动器同时定位带盒。

摘要： In a tape drive (10) comprising a conductive chassis (20) having a front bezel (21) formed on its front side and circuit components mounted on the front bezel, such as a switch (22) for an eject button (251) and light-emitting diodes (23), the front bezel (21) is provided with a projection (211) formed thereon to project forward in the vicinity of the switch (22). Thus, the projection (211) has a function as a lightning rod. The front bezel (21) is covered with a front panel (25). The chassis (20) has a lower surface (20L) covered with a circuit board (90). The circuit board and the above-mentioned circuit components are electrically connected with each other through a flexible printed circuit (27).

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 large-capacity flexible disk having a case accommodating a magnetic disk medium, the case is provided with a single large-capacity identifier hole formed in the vicinity of a write protection hole to discriminate the large-capacity flexible disk from a small-capacity flexible disk. The large-capacity flexible disk is one of a plurality of types having storage capacities different from one another. The case is further provided with type identifier holes selectively formed to identify the type of the large-capacity flexible disk so that the type of the large-capacity flexible disk can be identified with reference to the number and the position of the type identifier holes. In a high-density type flexible disk drive capable of accessing a large-capacity flexible disk having a case accommodating a magnetic disk medium, the case being provided with a single large-capacity identifier hole formed in the vicinity of a write protection hole to discriminate the large-capacity flexible disk from a small-capacity or a medium-capacity flexible disk, a large-capacity detecting switch is provided at a position corresponding to the large-capacity identifier hole.

摘要： In the engaging structure of a lead screw (51) with a head lift body (52), for simplification of a feeding side mechanism and improvement of feeding accuracy, the head lift body has only one fingernail shaped protrusion (551) as a member engaging with an external thread of the lead screw (51). The protrusion (551) is provided on an internal wall surface of a bearing portion (55) formed in an integral structure with the head lift body (52). Accordingly, the engagement of the external thread of the lead screw and the single protrusion converts the rotation movement of the lead screw (51) to the linear movement of the head lift body (52). As a result, a feeding accuracy in the linear movement converted from the rotation movement is only determined by a feeding accuracy of only the lead screw (51). In an example, the protrusion is a half-moon shaped plate.

摘要： In a take-up reel for use in taking up a tape, a pair of flanges are connected to opposite ends of a cylindrical reel hub in an axial direction thereof, respectively. A take-up region is defined between the flanges as a region where the tape is taken up. Each of the flanges comprises a plurality of vanes extending outward from the reel hub in directions different from one another. Each vane has an inner peripheral portion and an outer peripheral portion smaller in mass than the inner peripheral portion.
