Texto 1:

Como não tinha teclado, você tinha primeiro que escolher a letra com o ponteiro e, depois, apertar o botão para a letra ser impressa. Devia ser trabalhoso e demorado. Texto do blog.

Texto 2:

The index typewriter came into the market in the early 1880s. The index typewriter uses a pointer or stylus to choose a letter from an index. The pointer is mechanically linked so that the letter chosen could then be printed, most often by the activation of a lever.

The index typewriter was briefly popular in niche markets. Although they were slower than keyboard type machines, they were mechanically simpler and lighter. They were therefore marketed as being suitable for travellers and, because they could be produced more cheaply than keyboard machines, as budget machines for users who needed to produce small quantities of typed correspondence. For example, the Simplex Typewriter Company made index typewriters for 1/40 the price of a Remington typewriter.

The index typewriter's niche appeal however soon disappeared as, on the one hand new keyboard typewriters became lighter and more portable, and on the other refurbished second-hand machines began to become available. The last widely available western index machine was the Mignon typewriter produced by AEG which was produced until 1934. Considered one of the very best of the index typewriters, part of the Mignon's popularity was that it featured interchangeable indexes as well as type, fonts and character sets. This is something very few keyboard machines were capable of, and only at considerable added cost.

Although they were pushed out of the market in most of the world by keyboard machines, successful japanese and chinese typewriters are of the index type, albeit with a very much larger index and number of type elements.

Embossing tape label makers are the most common index typewriters today, and perhaps the most common typewriters of any type still being manufactured.

The platen was mounted on a carriage that moved horizontally to the left, automatically advancing the typing position, after each character was typed. The carriage-return lever at the far left was then pressed to the right to return the carriage to its starting position and rotating the platen to advance the paper vertically. A small bell was struck a few characters before the right hand margin was reached to warn the operator to complete the word and then use the carriage-return lever. Trecho de texto da Wikipédia.
