Casio Computer Co., Ltd. is a multinational electronic devices manufacturing company founded in 1946, with its headquarters inShibuya, Tokyo, Japan. Casio is best known for its calculators, audio equipment, PDAs, cameras,musical instruments, and watches.
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.
In 1957 Casio released the Model 14-A the world’s first all-electric compact calculator, which was based on relay technology. 1957 also marked the establishment of Casio Computer Co. Ltd.

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.
