    • A helical scanning type of magnetic recording/reproducing apparatus in which a first entrance-side tape height regulation guide is disposed in a level higher than a center of a plane of rotation of magnetic heads mounted on a rotary drum assembly when the magnetic tape is loaded on the rotary drum assembly, and a first exit-side tape height regulation guide is disposed in a level lower than the center of the plane of rotation of the magnetic heads. The rotary drum assembly is disposed in a higher position such that its upper end is in the same level as an upper end of a lid of a tape cassette. The cassette is disposed at a lever lower than that of the first exit-side tape height regulation guide. The first entrance-side and the first exit-side tape height regulation guides are driven by a loading ring inclined towards the cassette so as to move while engaging with the magnetic tape during loading or unloading. A capstan motor is accommodated in a space formed between the inclined loading ring and a main chassis. This construction enables reductions in the overall thickness and the weight of the apparatus.
    • 一种螺旋扫描型磁记录/再现装置,其中第一入口侧带高度调节引导件设置在高于安装在旋转鼓组件上的磁头的旋转平面的中心的高度,当磁带被装载时 并且第一出口侧带高度调节引导件设置在比磁头的旋转平面的中心更低的水平处。 旋转鼓组件设置在更高的位置,使得其上端与带盒的盖的上端处于相同的高度。 盒子设置在比第一出口侧带高度调节引导件低的杆处。 第一入口侧和第一出口侧带高度调节引导件由朝向盒倾斜的装载环驱动,以便在装载或卸载期间与磁带接合时移动。 主导轴马达容纳在形成在倾斜加载环和主底盘之间的空间中。 该结构能够减小装置的整体厚度和重量。

    • A disk cartridge is provided in which if the width of the disk cartridge is W1 and the outside diameter of the disk is D1, then W1 is about the same as D1. Inside the disk cartridge is a disk space in which the disk can rotate. A movement restricting portion restricts movement of the disk in the direction parallel with a disk surface. A cutout that extends through into the disk space is provided in part of a surface forming the width of the disk cartridge. A protrusion is provided in the surface adjacent to the surface in which the cutout is provided and at a position near the cutout.
    • 提供一种盘盒,如果盘盒的宽度为W1,盘的外径为D1,则W1与D1大致相同。 磁盘盒内部是磁盘空间,磁盘可以旋转。 移动限制部分限制盘在与盘表面平行的方向上的移动。 在形成盘盒的宽度的表面的一部分中设置有延伸穿过盘片空间的切口。 在与设置有切口的表面相邻的表面中设置有突起,并且位于靠近切口的位置处。

    • A magnetic tape recording and reproducing plug-in unit including a case with a front plate having an insertion opening through which a magnetic tape cassette is inserted, a bottom plate, a top plate, and a pair of side plates each formed with a pair of guide slots arranged for guiding the cassette to a loading position. The slide plates are attached to the side plates so as to be slidable within the case, each slide plate formed with a pair of cam slots arranged for moving the cassette to the loading position. A cassette holder is disposed inside the pair of slide plates for holding the cassette and has pins extending through the cam slots into the guide slots of the side plates. A recording and reproducing device is mounted on the bottom plate. A driving device drives the slide plates. An electronic circuit is disposed at the rear of the recording and reproducing device. Each of the guide slots has a horizontal guide slot portion extending depthwise and a vertical guide slot portion extending downward from the horizontal guide slot portion. Each of the cam slots has a horizontal cam slot portion extending depthwise and an oblique cam slot portion extending obliquely upwards from a rear end of the horizontal cam slot portion.
