When and when did the keyboard invent?

When and when did the keyboard invent?

When was the first keyboard invented?

With many inventions, many different inventions, including typewriters, teleprinters, and key pin, which help us to move up to the modern computer keyboard used by us today. The first writing device was prepared in the beginning of the 1700s and was first patented in 1714 by Henry Mill in London England.

Invention of typewriter

In the early 1700s and early 1800s, many typing and writing devices were created around the world. However, the first practical typewriter and term "typewriter" was first developed and patented by Christopher Sholes in 1868 and is considered as the first typewriter. In addition, the type-writer introduced the QWERTY layout, which is still used on almost all-American keyboards. Below is a picture of a typewriter created by Christopher Sholes, Carlos Glidden and Samuel W. Soule.

In 1878 Remington was the first keyboard to hold a Shift key on the No.2 typewriter, with a shift key on the left side of the keyboard.

The first successful modern typewriter is considered underwood typewriter, which sold five million typewriters until 1939. The first underwood typewriter was invented by Franz Xavier Wagner, who patented the typewriter on U.S. patent 523,698 on April 27, 1893. The biggest improvement for this typewriter was the ability to see the writing because it was typed. Later with the help of John Underwood, he created Underwood Company in 1895 and released his first typewriter in 1896.

In the early 1900s, the typewriters of all manufacturers began to become alike, as long as IBM did not present their IBM Sequence typewriter on July 27, 1961. Unlike other typewriters, it used a typewril, which had a small ball that would kill an ink ribbon. In it typeballs were removable, which allowed the user to clean them when needed and even improves the change or font in other typeballs for replaces. By 1986, more than 13 million typewriters were sold.

The invention of telegraph, keychain and teleprinter

During the second half of the 1700s, Joseph Marie Jacquard developed the Jacquard loom, which later expanded in the late 1800s and early 1900s with Harman Holrith with his keypunch invention.
The invention of the electric telegraph was first invented by Pavel Schilling in 1832 and was allowed to use the single key to send Morse code messages in one row. Later, the Royal Earl House patented a printing telegraph in 1846, in which 28 piano-style keys were used. The keys were used to represent each letter of the alphabet and to make everyone easier to send messages.
In 1874, Emile Baudot invented the bodote code, which was later led by Donald Murray, who invented the telegraphic typewriter, which later became a teleprinter. Charles Krum continued the work of Frank Pearne to help in the invention of the developed teleprinters from 1902 to 1918. During this time, in August 1907, he patented the U.S. Patent 862,402, patent 8,88,335 in May 1908, and in May 1910 issued 1,286,351 patents.

First computing device with teletype machines
The first digital computer is known as ENIAC, which was completed in 1946 and used a teletype machine to input data into the computer. Although today's computer is very different than the keyboard, the teletype machine punched the pores in the punch card and then showed in the card reader.

Later in 1948, BINAC computers took electromagnetic control of teletype close to today's computers, which allowed the computer to input data and print results.

Early computer with keyboard

Several years after the introduction of MULTICS in 1964 and Video Display Terminals (VDT) allowed users to see what they were typing on the screen.

In 1969, Computer Terminal Corporation started shipping Datapoint 3300, the first computer terminal to replace the teleprinter. Also, being sold as Datapoint 3300, other versions of this terminal were sold as DEC VT06 and HP 2600A. Datapoint 3300 used the screen display typed text and was able to move the cursor using the arrow keys. It can also clear all the text till the end of the screen.

In the early 1970s, the keyboard began to use similar to today, which were heavy mechanical keyboards and electric typewriters were changed from IBM's companies. However, first personal computers such as Altair still used to switch off the switch on input data in front of the computer.

In the late 1970s, Apple Radio Shack and Commodore released all versions of their computer with the keyboard, which was included with the computer. In August 1981, IBM released IBM PC and a model known as Model F

In 1986, IBM released the Model M keyboard, which looks like most keyboards look like with today's function keys at the top of the keyboard. Model M is still a high keyboard, because it features a 101-key standard US layout which is used today for full size keyboards. It has also been optimized for the 104-key layout for the Windows keyboard with the Windows key and menu key.

Since the release of the IBM Model M keyboard, there are many changes in the keyboard that we use today. A membrane manufacturer makes computer keyboard very easy and cheap. The membrane keyboard makes the keyboard lightweight and slim than the first mechanical keyboard.
