摘要： A tray for inserting a memory card into a portable computer is described. The tray facilitates complete insertion of the memory card into the computer and optimum electrical interconnection between the memory card and the computer interior. The tray is dimensioned such that it creates a tight seal with the computer housing and provides a coplanar fit with the exterior of the computer housing. No portions of the tray or memory card protrude beyond the computer housing, thereby improving the durability, maneuverability, and compactness of the portable computer. A stop mechanism restrains the tray within the housing when the tray is opened. A memory card can easily be placed thereinto or removed therefrom when the tray is opened and yet the tray does not become separated from the computer and lost.

摘要： A pocket-type computer encompassed by a two-part hinged casing has a hinge structure in which a lower housing containing a computer keyboard has a pair of spaced hinge elements pin-connected to an elongated hinge element of an upper housing containing a computer display panel. An elongated small leaf spring is captured within a slot on an exterior surface of a rear wall of the lower housing so that the bowed medial portion of the spring rides on a curved cam surface at the rear bottom edge of the upper housing during opening and closing of the respective housings forming the casing. Sufficient spring force is provided by the leaf spring so that the upper housing can be rotated with respect to the lower housing to an infinite number of angular positions and when the rotation is stopped allows the housings to stay in the then fixed angular position with the compressive force and friction of the leaf spring being sufficient to overcome the force of gravity tending to close the upper housing onto the lower housing. In a preferred embodiment the frictional force is constant since the cam surface is of a constant radius of curvature.
摘要翻译：由两部分铰链外壳包围的袖珍式计算机具有铰链结构，其中包含计算机键盘的下壳体具有一对间隔开的铰链元件，该铰链元件与上壳体的细长铰链元件销连接，该铰链元件包含计算机显示面板。细长的小板弹簧被捕获在下壳体的后壁的外表面上的槽内，使得弹簧的弓形中间部分在打开和关闭期间在上壳体的后底边缘处的弯曲的凸轮表面上骑形成壳体的各个壳体。板簧提供足够的弹簧力，使得上壳体能够相对于下壳体旋转至无限数量的角位置，并且当旋转停止时，允许壳体保持在然后固定的角位置，压缩板簧的力和摩擦力足以克服倾向于将上壳体关闭到下壳体上的重力。在优选实施例中，摩擦力是恒定的，因为凸轮表面具有恒定的曲率半径。

摘要： A pocket-type computer encompassed by a two-part casing has the entire latch mechanism contained in sidewalls of upper and lower hinged casings. The sidewalls have a thickness of only about two millimeters. A latch plate is integrally molded in a sidewall interior recess or formed as a molded part and fixedly adhered in the recess. One end of an elongated latch is fixed in an interior recess in the upper casing sidewall and depends therefrom so that a centilevered end having locking tooth slides on an inclined surface on the latch plate as the casings are closed until the latch tooth springs into a recess and keeper in the latch plate. An integral push button extends outwardly from the latch at a medial position into a matching aperture in the upper casing sidewall. The push button is accessed from the casing exterior and when pushed inwardly, the latch is pivoted inwardly releasing the latch tooth from the latch keeper to allow opening of the two casings. After opening, a user can then operate the computer, more particularly a keyboard in the lower casing and view a display screen provided in the interior of the upper casing.
