History
A global innovator in the field of calculation
In 1965, CASIO released the Model 001, the company's first desktop electronic calculator and the world's first desktop calculator with a memory function.
CASIO went on to pioneer easy access to electronic calculation.
The evolution of microprocessors from transistors to integrated circuits to large-scale integrated circuits sparked worldwide competition to develop smaller, more accessible calculators.
CASIO created a sensation in 1972 with the introduction of the CASIO Mini, a product born out of creative ideas and highly advanced technologies that transformed the calculator from a tool for business use into an essential household item.
In step with technological evolution, CASIO calculators became increasingly smaller, lighter, multifunctional, and sophisticated.
CASIO went on to create a series of groundbreaking models that have left an indelible mark in the history of calculators.
One example is the SL-800, a credit card size calculator released in 1983 that has been archived at the Museum of Modern Art, New York.
At only 0.8 mm thick thanks to ultra-thin technology, the SL-800 was the world’s thinnest calculator*.
This handy product made it a common practice to carry around a calculator.
CASIO has also continuously driven evolution in the field of scientific calculators that require even more advanced technologies, supporting countless students, engineers, and researchers.
CASIO's long history of innovation in calculation has played an essential role in the history of science.
