Abstract

Most typewriters are equipped with a visual device, which indicates how close the typed information is to the bottom of the page. However, these types of devices require frequent monitoring by the operator to ensure that the bottom margin of the typed page is not encroached by the typed material. This is an interruptive procedure, which requires constant shifting of the eyes of the operator from the work being typed to the indicator device and then back again to the work, etc.

Most typewriters are equipped with a visual device, which indicates how close the typed information is to the bottom of the page. However, these types of devices require frequent monitoring by the operator to ensure that the bottom margin of the typed page is not encroached by the typed material. This is an interruptive procedure, which requires constant shifting of the eyes of the operator from the work being typed to the indicator device and then back again to the work, etc.

A concept for allowing the operator to type a complete page without visually monitoring the position of the typed material on the page is disclosed whereby a bottom margin indicator is provided, which emits an audible signal to the operator when the typed material reaches the position on the paper where the bottom margin is desired. The operator depress a switch, which activates the circuitry of the bottom margin indicator. The paper length dimension and/or the desired bottom margin dimension could be inserted into the system via two dials located on the typewriter. The operator then inserts the paper in the typewriter and adjust the paper for the-desired top margin in the normal fashion. The operator then types the page in the normal fashion. The bottom margin indicator monitors the position of the typed material on the paper and/or the bottom edge of t...
