Typebars are mechanical components found in traditional typewriters. They are metal arms that strike the inked ribbon against paper to create letters and symbols. Each typebar corresponds to a specific character, and when a key is pressed, the associated typebar moves forward to print the character on the page. In a typewriter, multiple typebars are arranged in a way that allows them to move independently. This design enables the user to type quickly, but it can also lead to jamming if two typebars collide. Despite their simplicity, typebars were essential for the functionality of early mechanical writing devices.
