Abstract: The invention pertains to developments for manipulating and referencing a magnetic tape cassette in a magnetic tape device involving loading, read/write and tape drive operation, and unloading. To load and unload the tape cassette, a tape drive bridge on which the magnetic head is mounted is disposed in a standby position out of the way of the path of movement of the tape cassette into and out of the recorder housing. A gripper disposed for longitudinal movement on a gear rack in the recorder housing, is arranged to bite the cassette to automatically carry the cassette inwardly to its fully loaded position and then again move the cassette outwardly to its unloaded position. A lever arm arrangement is provided to appropriately open the dust cover door on the tape cassette, to expose the cassette tape for operational engagement by the magnetic head, as the tape cassette approaches its fully loaded position within the recorder housing. The gear rack serves to activate this lever arm for opening the dust cover. The tape cassette is preferably loaded endwise into the recorder housing, and when the cassette has been fully loaded in the recorder housing, the tape drive bridge carrying the magnetic head is rotated in all three axes from its standby position to its running position. In its running position, the tape drive bridge locks the tape cassette to it, by gripping the cassette at three reference areas on the bridge. A manual eject mechanism utilizes an exposed button on the recorder housing which is manipulated by the operator to causing unloading of a stranded tape cassette, should the electrical system not work.

Abstract translation: 本发明涉及用于操作和参考包括加载，读/写和磁带驱动操作和卸载的磁带装置中的磁带盒的开发。 为了装载和卸载磁带盒，安装有磁头的磁带驱动器桥被布置在待机位置，使磁带进入和离开记录器壳体的路径移动。 布置成用于在记录器壳体中的齿条上纵向移动的夹持器布置成咬合盒子以将盒自动地向内运送到其完全装载的位置，然后再次将盒子向外移动到其卸载位置。 提供了一个杠杆臂布置，以适当地打开带盒上的防尘盖门，以便当磁带盒接近其在记录器壳体内的完全装载位置时，使磁带露出磁带以进行与磁头的操作接合。 齿条用于启动该杠杆臂以打开防尘罩。 磁带盒最好是以端向方式装入记录器外壳，当磁带盒已经完全装入记录器外壳时，承载磁头的磁带驱动桥在所有三个轴线上都从其待机位置转到其运行位置。 在其运行位置，磁带驱动器桥将磁带盒锁定到其上，通过在桥上的三个参考区域抓住磁带。 如果电气系统不起作用，手动弹出机构使用操作者操纵的记录器外壳上的暴露按钮来使绞合的磁带盒卸载。
