Abstract

This indicator provides a method for effecting a rapid changeover of keyboard character designations, to correspond with various types of ball type elements used on typewriters. With IBM's Selectric Typewriters the type can be changed by merely interchanging the ball type element. This interchangeability concept can be further extended by providing a ball element having type characters other than the alphabet, or to at least include different type characters in addition to the alphabet characters.

Interchangeable Keyboard Character Indicator

This indicator provides a method for effecting a rapid changeover of keyboard character designations, to correspond with various types of ball type elements used on typewriters. With IBM's Selectric Typewriters the type can be changed by merely interchanging the ball type element. This interchangeability concept can be further extended by providing a ball element having type characters other than the alphabet, or to at least include different type characters in addition to the alphabet characters.

This interchangeable keyboard character indicator consists of frame 10 surrounding the keyboard and of a height equal to the height of the keys. Frame 10 is attached to the keyboard by screws. Character template 12, which can be polyethylene to insure flexibility, is provided with key designations 14 corresponding to a given ball type. Template 12 is supported on frame 10 and held in place by second frame 16. The assembly is secured together by suitable means. Template 12 must be sufficiently flexible so that only the key depressed will respond and not the adjacent keys. The indicator provides a solution to the problem of converting keyboards to conform with the typing element used, thus increasing the versatility of existing typewriters.
