Abstract

A small typewriter of simple construction which can be carried by one hand is illustrated in the drawing. Construction of the machine is unique. The operator never actually sees the writing line. A keyboard 1 and display 2 cover the complete machine, making possible the small size of approximately 10 inches by 12 inches overall. The display 2 will act as a writing line, and the operator may see typing on the various lines of the display. In this manner, it is possible to make correction before printing by use of the display, therefore eliminating the necessity for a correction ribbon.

Compact Flat Bed Display Typewriter

A small typewriter of simple construction which can be carried by one hand is illustrated in the drawing. Construction of the machine is unique. The operator never actually sees the writing line. A keyboard 1 and display 2 cover the complete machine, making possible the small size of approximately 10 inches by 12 inches overall. The display 2 will act as a writing line, and the operator may see typing on the various lines of the display. In this manner, it is possible to make correction before printing by use of the display, therefore eliminating the necessity for a correction ribbon.

A pair of bars 3 and 4 eliminate the need or requirement for a print carrier, escapement mechanism or index mechanism. The escapement bar 3 as well as the index bar 4 are driven by a stepper motor 5 by way of a single belt 6 which is wrapped upon pulleys and surrounds the perimeter of paper 7 upon Which the indicia, found on the display 2, will be imprinted. If the machine is escaping, a pair of magnetically actuated clamps 8 secure the escapement bar 3 to the belt 6, allowing the stepper motor to drive the escapement bar only. Magnetic clamps 9 at the same time will be free of the belt 6, and the index bar 4 is unable, therefore, to move. Alternatively, when it is desired to index, the magnets 9 will allow clamping of the index bar 4 to the belt 6 such that movement of the belt will effect movement of bar 4, while the magnets 8 will be disengaged...
