    Abstract: A device (10) adding apparatus as a keyboard input to a handheld computer (12) lacking such input (such as pen computers and personal digital assistants) includes a keyboard (11) and a planar motion pivot mechanism (30). Planar motion pivot mechanism (30) includes a body (31) formed as a boot that encloses an end of the handheld computer (12), and a pivot pin (32). The user simply rotates keyboard (11) from a nonoperational position substantially covering the handheld computer display (14), to an operational position at substantially a right angle to the display (14).

    Abstract translation: 将装置（10）作为键盘输入添加到缺少这种输入的手持式计算机（12）（诸如笔式计算机和个人数字助理）中的装置包括键盘（11）和平面运动枢转机构（30）。 平面运动枢转机构（30）包括形成为围绕手持式计算机（12）的端部的引导件的主体（31）和枢轴销（32）。 用户简单地将键盘（11）从基本覆盖手持式计算机显示器（14）的非操作位置旋转到与显示器（14）基本成直角的操作位置。
