What it is Filled

A mechanical, electromechanical or electronic machine that prints characters one at a time onto paper, usually by striking a type element against an inked ribbon, operated from a keyboard.

Why it exists Filled

Let an agent identify a typewriter by type, maker era and mechanism, describe its care, and handle questions about typewritten documents.

Distinguishing features Filled

  • Prints onto paper itself; manual and most electric models print on each keystroke, electronic models may buffer text first.
  • Memory depends on the model: none, a correction buffer, or stored phrases and documents.
  • Differs from a teleprinter, which sends and receives text over a line.

What robots and AI may and may not do Filled

Must not

  • advise opening electric models while connected to mains
  • claim authorship of a typed document from typeface alone
  • give a valuation as definitive

Only with a human decision

  • forensic attribution of a typed document

May

  • help identify and date a machine
  • explain care and ribbon replacement

Moral aspects Filled

  • privacy of typed documents and letters
  • fair forensic attribution

Who is affected

  • authors of typed documents
  • collectors and owners

Owners Filled

Steward

the person who owns the machine

Master systems

  • maker serial number records and collector databases

Links to other meta-models Filled

parent

  • Q11019 - registry parent class

related

  • machine - a writing machine
  • typewriter ribbon - consumable of most impact typewriters
  • teleprinter - networked typing machine
  • computer keyboard - layout heritage such as QWERTY

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.typewriter
  • Wikidata: Q46335 (https://www.wikidata.org/wiki/Q46335)
  • serial number: maker-specific pattern used to date a machine with maker serial lists

Direct properties required Filled

  • mass: 3-20 kg - portables at the low end, office standards at the high end
  • line spacing: single to triple - commonly 6 lines per inch at single spacing
  • pitch: 10-12 characters per inch - pica and elite

Recognition required Filled

  • Platen roller with paper bail
  • Fan of typebars or a single type ball or daisy wheel
  • Carriage return lever on manual machines
  • A keyboard machine with a platen roller holding paper, typebars or a single type element and usually a ribbon; either the paper carriage or the typing element moves across the line. Portables fit in carrying cases.

Capabilities and actions required Filled

  • identify the type and approximate date of a machine
  • explain how the mechanism works
  • advise on ribbon replacement and basic care
  • describe forensic examination of typed documents in general terms

Hazards and failure modes required Filled

  • Seized mechanism from old lubricant and dust
  • Dried ribbons
  • Pinched fingers in typebar baskets
  • Mains wiring faults in old electric models

Standards and interfaces required Filled

  • Keyboard layouts such as QWERTY descend from typewriters; ISO/IEC 9995 standardises keyboard layouts for computers

Context of use required Filled

  • Producing legible typed text on paper without handwriting or a printing press.
  • manual typebar typewriter
  • portable typewriter
  • electric typewriter
  • typeball typewriter
  • daisy-wheel electronic typewriter
  • braille writer

  2. Typewriter - general description of the subject
  3. Typewriter ribbons and carbon paper, Circular 431 - ribbons, pica and elite pitch
  4. Forensic Database Questioned Documents Table - typewriter comparison in document examination

Open questions

  • Should braille writers and stenotype machines be kinds here or separate entries?
  • Maker and model belong to the individual machine; how should brand records link?
