摘要： A portable personal computer has a display screen movable between a substantially vertical position when a keyboard is in a substantially horizontal position and exposed for use and a substantially horizontal position in which the keyboard is not accessible or viewable but the display screen is accessible and viewable. In its substantially horizontal position, the display screen can be used as a book reading device or a pen based personal computer, for example. When the display screen is in its substantially horizontal position, function control buttons are accessible.

摘要： Disclosed is a mechanism for shifting the rack of a selection mechanism for a single element printer from one position to another in timed relationship to the translation of a barrel cam which provides the necessary mechanical input to control the amount of rotation of the typehead. The control of the rack shift mechanism is a cam arrangement operated in timed relationship with the translating barrel cam to provide for the shifting of the rack at the beginning of each print cycle, if necessary, and the retaining of the rack in its shifted position at the completion of the cycle, thereby eliminating the necessity to provide for the time required to shift the rack back to its home position at the end of the cycle. The elimination of the restore operation of the rack provides more time during the cycle to operate the selection mechanism and accomplish printing or conversely provides for a smaller amount of time being required for the necessary functions thereby providing the capability of operating the remainder of the mechanism at a faster rate.

摘要： A long keybutton is stablized with a pair of arms and an interconnecting shaft. The ends of the arms are connected to the keybutton using a thin serpentine section which distributes stress and forces to improve life of the part, and permits integral molded keybuttons. The integral molded part with the stability of the portions of the keybutton permits the automated assembly of the stabilized keybutton with the keyboard frame.
