例句與造句
- The keyboard layout was designed partly to insure that typebars would not jam if the operator typed too quickly.
- It mechanically locked the typebars in the shifted position, causing the upper character to be typed upon pressing any key.
- As with most other early typewriters, because the typebars strike upwards, the typist could not see the characters as they were typed.
- In mechanical typewriters, the shift key functions by mechanically shifting some component so an alternate row of characters on typebars hits the paper.
- The size and usability implications of adding additional keys and thus, more typebars, precluded the addition of a fourth keyboard row dedicated to numbers.

- The name " Carriage Return " comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary.

- Typewriter eraser brushes were necessary for clearing eraser crumbs and paper dust, and using the brush properly was an important element of typewriting skill; if erasure detritus fell into the typewriter, a small buildup could cause the typebars to jam in their narrow supporting grooves.
- The typeball design had many advantages, especially the elimination of " jams " ( when more than one key was struck at once and the typebars became entangled ) and in the ability to change the typeball, allowing multiple fonts to be used in a single document.
- Due to their speed ( 14.8 characters per second ), immunity to clashing typebars, trouble-free paper path, high quality printed output, and reliability, Selectric-based mechanisms were also widely used as terminals for computers, replacing both Teletypes and older typebar-based output devices.
- Instead of the " basket " of individual typebars that swung up to strike the ribbon and page in a traditional typewriter, the Selectric had a type element ( frequently called a " typeball ", or more informally, a " golf ball " ) that rotated and pivoted to the correct position before striking.
