    • A disk drive motor (5) for driving and rotating a recording medium (disk), a head (57) for recording or playing back information to/from this disk, and a head drive mechanism for driving the head, are disposed inside a case body (15, 16) of the magnetic recording unit. A lid body (17) to close the cartridge insertion slot (18) is disposed the case body (15, 16) at a position facing the cartridge insertion slot (18). When the lid body (17) falls down the front side and the cartridge insertion slot (18) is opened, the top face of the lid body (17) becomes substantially on the same plane as the top face of the frame plate where the disk drive motor (5) and the head (17) drive mechanism are mounted.

    • A card-type electronic device comprises a casing (4) composed of a rectangular frame (5) and two covers (6, 7) individually covering the upper and lower surfaces of the frame (5). Substantially U-shaped retaining pieces (11a, 11b) are formed by bending tongues (10), which partially protrude from the long side edge portions of the covers (6, 7), so that their distal ends are directed toward the other covers (6, 7) and further bending the distal ends on the inner peripheral side. On the other hand, the side faces of the frame (5) are formed with recesses (19a, 19b) for vertically guiding the retaining pieces (11a, 11b) and retaining portions (20a, 20b) adapted individually to engage the retaining pieces (11a, 11b) fitted in the recesses when the retaining pieces slide in the longitudinal direction of the casing (4).
    • 卡式电子设备包括由矩形框架(5)组成的壳体(4)和分别覆盖框架(5)的上表面和下表面的两个盖子(6,7)。 基本上U形的保持件(11a,11b)通过弯曲的舌片(10)形成,舌片部分地从盖子(6,7)的长边缘部分突出,使得它们的远端指向另一个盖子 6,7),并进一步弯曲内周侧的末端。 另一方面,框架(5)的侧面形成有用于垂直引导保持片(11a,11b)的凹部(19a,19b)和分别适于接合保持片的保持部(20a,20b) 11a,11b),当所述保持片沿着所述壳体(4)的长度方向滑动时嵌合在所述凹部中。

    • In a disc drive unit, a notch or opening is provided in a part of a lower case body, out of upper and lower case bodies containing therein a functional member, such as a spindle motor, whereby a part of the functional member, of which the vertical dimension cannot be reduced with ease, is exposed. Thus, a clearance dimension that is required when there are no holes, as well as the thickness dimension of the lower case body, is supposed to be a part of the vertical dimension that the functional member can utilize, whereby the overall vertical dimension of the unit is reduced without lowering the performance of the functional member.
    • 在盘驱动单元中,在下壳体的一部分中设置有凹口或开口,其中包含诸如主轴电动机的功能构件的上壳体和下壳体,其中功能构件的一部分 垂直尺寸不能轻易降低,暴露。 因此,当没有孔时所需的间隙尺寸以及下壳体的厚度尺寸被认为是功能构件可以利用的垂直尺寸的一部分,由此,整体垂直尺寸 在不降低功能元件的性能的情况下减小单元。

    • A disk drive device (1) comprises a body chassis (2) and a tray (3) movable relative to the body chassis (2). The body chassis (2) is provided with a stage (6) at one side thereof, which is higher than the central bottom face. On the other hand, a part of the disk protective portion (11) of the tray (3), which overlaps the stage (6), is cut out at its rear end (20a) in an arc shape. As a result, the disk protective portion (11) covers the whole area of a disk (14) and, at the same time, forms a large space between it and the front end (6a) of the stage (6).
    • 磁盘驱动装置(1)包括主体机架(2)和相对于主体机架(2)可移动的托架(3)。 主体底架(2)在其一侧设置有比中心底面高的台(6)。 另一方面,托盘(3)的与托架(6)重叠的盘保护部(11)的一部分在其后端(20a)处被切割成弧形。 结果,盘保护部(11)覆盖盘(14)的整个区域,并且同时在其与台(6)的前端(6a)之间形成较大的空间。
