is a Japanese multinational
electronics manufacturing company headquartered in Shibuya
. Its products include calculator
s, mobile phone
s, digital camera
s, electronic musical instrument
s, and analogue
and digital watch
es. It was founded in 1946, and in 1957 introduced the world's first entirely electric compact calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the world's first mass-produced digital watches.
Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio (樫尾忠雄
1917–1993), 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 (Toshio, Kazuo, and Yukio) used their profits from the yubiwa pipe to develop their calculators. Most of the calculators at that time worked using gears and could be operated by hand using a crank or using a motor (see adding machine
Toshio possessed some knowledge of electronics and set out to make a calculator using solenoid
s. The desk-sized calculator was finished in 1954 and was Japan's first electro-mechanical calculator. One of the central and more important 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 distinguishing 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.
Casio Computer Co., Ltd. was formed in June 1957.
That year, 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.
In the 1980s, Casio's budget electronic instruments and its line of affordable home electronic musical keyboard instruments
became popular. The company also became well known for the wide variety and innovation of its wristwatch
es. It was one of the earliest manufacturers of quartz watch
es, both digital and analog. It also began selling calculator watches during this time. Casio also introduced one of the first watches that could display the time in many different time zone
s of the world and with features like recording temperature, atmospheric-pressure and altitude. In the later years, Casio's wristwatches were fitted with receivers to synchronise with radio towers around the world and Global Positioning System
for timekeeping accuracy.
A number of notable digital camera innovations have also been made by Casio, including the QV-10, the first consumer digital camera with a liquid-crystal display
(LCD) on the back
(developed by a team led by Hiroyuki Suetaka in 1995), the first consumer three-megapixel camera, the first true ultra-compact model, and the first digital camera to incorporate ceramic lens technology, using Lumicera
In July 2019, the company's UK arm, Casio Electronics Co. Ltd, was fined £3.7 million after admitting resale price maintenance
(a form of price-fixing
) between 2013 and 2018, in breach of the United Kingdom's Competition Act 1998
Casio's products include watch
s, electronic keyboard
s and other digital products such as digital camera
series), film camera
s, cash register
s and sub-notebook
computers, mobile phone
(E-Data Bank), electronic dictionaries
, digital diaries
(early PDAs), electronic games
, computer printer
s, and portable televisions
In the 1970s and 80s, Casio was best known for its electronic (including scientific) calculators, electronic musical instruments and affordable digital watches incorporating innovative technology. Today, Casio is most commonly known for making durable and reliable electronic products.
/ref> The G-Shock range of shock-resistant watches is also very popular, with the original 1983 G-Shock DW-5000C being highly sought-after by collectors. The scientific calculators made by Casio especially the CLASSWIZ series of calculators are known for being affordable while incorporating a host of functions as compared to their competitors.
Casio also makes products for local markets, including "Prayer Compass" watch series designed to help Muslims pray on time and in the right direction.
