Question

What is the basic sequence of operation of the key /bar type writer?
A. The typist strikes the key on the keyboard
B. The ribbon transfers the impression to the sheet of paper behind it and the platen absorbs the force of the strike
C. As the key bar falls back into place, the carriage usually moves one unit to the next typing space and ribbon advances
D. The type block strikes the ribbon
E. Through mechanical linkage or electric triggering, a type bar is thrown up from the type basket towards the platen

• A. A, E, D, B, C
• B. C, A, D, E, B
• C. A, B, C, D, E
• D. C, E, A, B, D

Hint:

Think of the typewriter as a chain reaction. The typist's finger press is the trigger, leading to the type bar's movement, the strike through the ribbon, and finally the carriage advancing. Each step logically follows the previous one.

Answer 1

The Correct Option is A

The operation of a mechanical typewriter follows a precise mechanical sequence.
Step 1: The process begins with the user's action.
A. The typist strikes the key on the keyboard.

Step 2: This action initiates a series of linked movements.
E. Through mechanical linkage, the key press causes the corresponding type bar to be thrown from the basket towards the platen (the roller holding the paper).

Step 3: The type bar makes contact to create the impression.
D. The type block (the character head on the bar) strikes the ink ribbon.

Step 4: The character is transferred to the paper.
B. The ribbon, now pressed by the type block, transfers its ink to the paper. The platen provides a hard surface for the impression.

Step 5: The machine resets for the next character.
C. As the type bar returns to the basket, a mechanism engages to move the carriage one space over and advance the ribbon slightly to present a fresh ink surface.
This logical flow matches the sequence A, E, D, B, C.
