Question

The common tension/s of a type writer?

• A. Rack tension
• B. Key tension
• C. Carriage tension
• D. All the above

Answer 1

Answer:

D. All the above

• Typebars: These are the metal arms that strike the ribbon to imprint characters on paper. Each typebar is attached to a pivot and is spring-loaded.

• Ribbon Vibrator: When a key is pressed, the corresponding typebar swings forward. Simultaneously, a mechanism lifts and vibrates the ink ribbon to ensure a clear impression.

• Carriage Return Lever: After a line is typed, this lever is used to move the carriage (the assembly holding the paper) back to the left margin and advance the paper to the next line. This action often involves a spring mechanism.

• Escapement Mechanism: This is a crucial part that controls the forward movement of the carriage. It releases the carriage one character space at a time as each key is struck, ensuring even spacing. It typically uses a spring-loaded pawl and ratchet system.

• Line Spacing Mechanism: This allows for adjusting the vertical space between lines (single, double, triple spacing). It's usually controlled by a dial or lever connected to the paper feed rollers, often utilizing a spring.
