lever and pulley
A typewriter contains many levers, as well as other simple machines. Electric typewriters contain fewer than manual versions.
The enter key has an analogous function to the return lever on a typewriter.
There should be a margin-set lever that can be slid further in or out to alter the travel of the carriage. The margin-set lever is often located next to the larger carriage release lever.
A lever that is third in line waiting to be lifted!
Open the cover, push the red lever on the right hand side of the ribbon towards the front of the typewriter, and lift the old ribbon off, replace with new ribbon, pull the lever back towards the keyboard and close the lid.

Typewriter
Assuming you mean a manual typewriter, here's what I can think of: 1) Keys (alphanumeric, symbol and function - could count as several "parts") 2) Spacebar 3) Carriage return / line space lever 4) Action bars 5) Typebars (known collectively as the typebasket) 6) Typeslugs (top of the typebars, with text dies on them) 7) Escapement mechanism 8) Carriage return spring 9) Draw-band 10) Carriage support (a separate item on some designs like the Olympia SG1) 11) Carriage 12) Frame 13) Shell 14) Feet 15) Carriage shift mechanism, or typebasket shift mechanism (depends on design) 16) Platen 17) Platen rollers 18) Paper table 19) Paper guide & guide plate 20) Paper bail & bail rollers 21) Platen knob(s) - usually two, sometimes just one on compact portables 22) Line space selector / indicator 23) Line space ratchet release 24) Carriage release 25) Margin indicators 26) Right margin bell 27) Margin release 28) Tab set key (if equipped) 29) Tab release (clears all tabs) and/or tab clear (one tab only) 30) Ribbon trays 31) Ribbon vibrator 32) Aligning scale 33) Card holder ...And I could go on. Pick the ones that seem most important to you. :-)
TYPEWRITER.
A Brother typewriter could do the lettering on business labels, envelopes, and letters. There are several functions on this. It could type underlined letters, superscripts, subscripts, bold letters, and other characters on the electronic Brother typewriter. This typewriter could also erase mistakes or whole line.
There are actually 47 keys including the space bar.
