Casio was established in April 1946 by Tadao Kashio, an engineer
specializing in fabrication technology. Kashio's first major product
was the yubiwa pipe, a finger ring that would hold a cigarette,
allowing the wearer to smoke the cigarette down to its nub while also
leaving the wearer's hands free. Japan was impoverished immediately
following World War II so cigarettes were valuable, and the invention
was a success.
After seeing the electric calculators at the first Business Show in
Ginza,
Tokyo in 1949, Kashio and his younger brothers used their profits from
the yubiwa pipe to develop their own calculators. Most of the
calculators at that time worked using gears and could be operated by
hand using a crank or using a motor. Kashio had some knowledge of
electronics, and set out to make a calculator using solenoids.
The desk-sized calculator was finished in 1954 and was Japan's first
electro-mechanical calculator. One of the central innovations of the
calculator was its adoption of the 10-key number pad; at that time
other calculators were using a "full keypad", which meant that each
place in the number (1s, 10s, 100s, etc...) had nine keys.

Another
innovation was the use of a single display window instead of the three
display windows (one for each argument and one for the answer) used in
other calculators.
In 1957 Casio released the Model 14-A, sold for 485,000 yen, the
world's first all-electric compact calculator, which was based on
relay technology. 1957 also marked the establishment of Casio Computer
Co. Ltd.
In the 1980s, its budget electronic instruments and home keyboards
gained huge popularity.
The company also became well known for the wide variety and innovation of its wristwatches. It is one of the early manufacturers of quartz crystal
watches, both digital and analog. It also began selling calculator
watches during this time. It was one of the first manufacturers of
watches that could display the time in many different time zones and of
watches with temperature, atmospheric-pressure, altitude, and even GPS
position displays. Today, Casio is most commonly known for durable,
large sized watches.
Especially popular are its dual function (LCD and analog) watches, some of which, called Wave Ceptors, receive radio signals daily from an atomic clock
to keep accurate time. These watches come with lengthy manuals(50 pages
each in English and Spanish, each the size of a business card): those
users who master all the intricate features will be able to tell time
in many time zones, use alarms and timers, and even follow
Daylight-Saving Time; those who ignore or misunderstand the manual can
expect many surprises.
A number a notable digital cameras firsts have been made by Casio,
including the first consumer digital camera with an LCD screen, the
first consumer 3 megapixel camera, the first true ultra-compact model,
and the first digital camera to incorporate ceramic lens technology.
