    • When an auto-reverse is designated in the state of the magnetic tape of a cassette being transferred in a first direction with a planetary gear meshing with a first reel gear, a motor reverses, and also a central gear reverses such that the planetary gear starts revolving around the central gear away from the first reel gear. The planetary gear meshes with a mode changing gear, and rotate the mode changing gear, a projection and a switching member. In accordance with the rotation of the switching member, a head base moves horizontally and a magnetic head separates from the magnetic tape. Further, a bent piece on the head base abuts against a stopper, due to which the revolution of the planetary gear stops, and the planetary gear stays to assuredly transmit the revolution of the central gear to the mode changing gear. Moreover, the projection while in rotation presses a slider. As the slider slides, the magnetic head turns 180.degree.. When the mode changing gear further rotates, the head base horizontally moves again in accordance with the rotation of the switching member, and the magnetic head comes into contact with the magnetic head. The bent piece also moves horizontally, as a result of which the bent piece and the stopper disengage from each other, and the planetary gear becomes revolvable and starts revolving around the central gear toward a second reel gear. The planetary gear meshes with the second reel gear, and drives the second reel gear to transfer the magnetic tape in the reverse direction. Thus, using the driving force generated by the motor, the reversal of the transfer direction of the magnetic tape, the rotation of the magnetic head and the movement of the head base are performed.
    • 当以与第一卷轴齿轮啮合的行星齿轮沿第一方向转移的盒的磁带的状态指定自动反转时,电动机反转,并且中心齿轮反转,使得行星齿轮起动 围绕中央齿轮转动离开第一卷轴齿轮。 行星齿轮与变速齿轮啮合,并且转动换档齿轮,突起和切换构件。 根据切换构件的旋转,头座水平移动并且磁头与磁带分离。 此外,头部基座上的弯曲件与止动器抵接,由此行星齿轮的转动停止,并且行星齿轮保持将中心齿轮的旋转确保地传递到换档齿轮。 而且,旋转时的突出部分按压滑块。 当滑块滑动时,磁头转动180°。 当模式改变齿轮进一步旋转时,头座基于切换构件的旋转而水平移动,并且磁头与磁头接触。 弯曲部件也水平移动,结果弯曲部件和止动器彼此脱离,行星齿轮转动并开始围绕中心齿轮朝向第二卷轴齿轮旋转。 行星齿轮与第二卷轴齿轮啮合,驱动第二卷轴齿轮沿相反方向传送磁带。 因此,使用由电动机产生的驱动力,执行磁带的传送方向的反转,磁头的旋转和磁头基座的移动。

    • A cooling structure for an electronic equipment rack which comprises a plurality of shelf units stacked one upon another and arranged in a cabinet, each shelf unit accommodating a plurality of printed circuit boards and having vent holes formed on upper and lower surfaces thereof respectively. A fan unit having at least one fan is disposed on top of each shelf unit to constitute a separate cooling block. The fan unit of each cooling block generates a cooling wind which is passed linearly through the shelf unit from the bottom to the top of the shelf unit as well as introducing atmosphere through vent holes formed on side face portions of each fan unit to mix the atmosphere with the cooling wind. As a result, the flow rate of the cooling wind will be gradually increased as the cooling wind proceeds to the upper cooling blocks due to the addition of an upward blowing force caused by the fans of the fan units.
