    • The magnetic recording/reproduction apparatus of this invention records/reproduces information on/from a magnetic tape by drawing out the magnetic tape from a tape cassette and allowing the magnetic tape to pass around a rotary head cylinder having a rotary head for a predetermined arc. The apparatus includes: a capstan shaft for driving the magnetic tape; a pinch roller for pressing the magnetic tape against the capstan shaft; a first reel base rotatably attached to a shaft, the first reel base engaging with a first reel for holding the magnetic tape wound onto the first reel located in the tape cassette; a second reel base rotatably attached to a shaft, the second reel base engaging with a second reel for holding the magnetic tape wound onto the second reel located in the tape cassette; and an idler supported swingably to swing to the second reel base when the capstan shaft is rotated in a first direction and to the first reel base when the capstan shaft is rotated in a second direction, wherein the idler includes a gear portion which rotates in association with the rotation of the capstan shaft, when the running of the magnetic tape is to be shifted from the first direction to the second direction, the rotation of the capstan shaft in the first direction stops, the pinch roller moves away from the capstan shaft, the capstan shaft is rotated in the second direction by a predetermined amount so that the idler swings to the first reel base, the capstan shaft stops again, the pinch roller presses the magnetic tape against the capstan shaft, and the capstan shaft is rotated again in the second direction to allow the magnetic tape to run in the second direction and the gear portion to be coupled with the first reel base, the gear portion rotating the first reel base in a direction in which the magnetic tape is wound onto the first reel.

    • A tape loading device of a magnetic recording/reproducing apparatus, is characterized by including: first and second tape guide posts (9,11) for taking a tape (14), extending between a supply side reel (3) and a winding side reel (4) of a tape cassette (2), from the tape cassette and travelling the tape to a predetermined position located outside the tape cassette; first and second loading guides (19,20) for respectively guiding travels of the first and second tape guide posts to take out the tape from the tape cassette to the predetermined position; a common guide (22) for joining a part of the first loading guide and a part of second loading guide into the same path so as to guide the first and second loading guides in order; and a branch pointer arm (24,25) for switching between the common guide and the first and second loading guides, the branch pointer arm being urged to open one loading guide of the loading guides and close the other loading guide thereof, and pressed by one tape guide post of the tape guide posts when the tape guide post, moving along the common guide in precedence to the other tape guide post, has guided by the one loading guide which has been opened, whereby the one loading guide is closed and the other loading guide is opened to guide the other tape guide post of the tape guide posts.
    • 磁记录/再现装置的磁带装载装置的特征在于包括:第一和第二磁带引导柱(9,11),用于拍摄磁带(14),其在供给侧卷轴(3)和卷绕侧卷轴 (2)的磁带盒(4),并且将磁带移动到位于盒式磁带外部的预定位置; 第一和第二装载引导件(19,20),用于分别引导第一和第二带引导件的行进,以将带从带盒取出到预定位置; 用于将第一装载引导件的一部分和第二装载引导件的一部分连接到同一路径中以便依次引导第一和第二加载引导件的公共引导件(22) 以及用于在公共引导件和第一和第二加载引导件之间切换的分支指针臂(24,25),分支指针臂被推动以打开装载引导件的一个装载引导件并且关闭其他加载引导件,并且被按下 当沿着公共导轨优先移动到另一带导向柱的带引导柱的一个装载引导件已经被打开的一个装载引导件引导时,带引导件的一个带导向柱,由此一个装载引导件关闭,并且 打开其他装载导向件以引导导带柱的另一带导向柱。

    • The invention relates to a loading mechanism for a magnetic recording/playback apparatus and is directed to provide a positioning mechanism which can reliably and fixedly position a loading boat with a quite simple structure when completing an operation of withdrawing a magnetic tape. The invention is also directed to provide a loading post driving and pressing device which can eliminate the need of using a two-staged gear fitted with a spring, position two loading posts under pressing by one urging means, and realize reduction of the size, weight and thickness. The invention is further directed to provide a loading post driving device in which a gear serving as a prime mover part has the two-stages structure to realize reduction of the size, weight and height, and driving force can be directly transmitted from the gear serving as a prime mover part of a large loading gear by using no geneva gear.
    • 本发明涉及一种用于磁记录/重放装置的装载机构,并且旨在提供一种定位机构,该定位机构在完成取出磁带的操作时能够以相当简单的结构可靠地并且固定地定位装载舟。 本发明的目的还在于提供一种加载柱驱动和加压装置,其可以消除使用装有弹簧的两级齿轮的需要,通过一个推动装置按压两个装载柱,并实现尺寸,重量的减小 和厚度。 本发明进一步涉及提供一种装载柱驱动装置,其中用作原动机部件的齿轮具有两级结构,以实现尺寸,重量和高度的减小,并且驱动力可以直接从齿轮传动 作为大型装载机的原动机部分,不使用日内瓦齿轮。
