Count on Casio calculators, now and forever.
For 60 years, Casio calculators have been easy to read, simple to use and durable. Yet today, we're reimagining their core identity from the ground up for a new future of the calculator. Designed with the spirit of Japanese manufacturing, the Casio calculator of the future will exceed modern expectations as a truly essential item. Casio calculators respond to individual user's needs, and make computation correctly. Casio calculators don't just make computation convenient. Just by owning one, they deliver joy.
History of Casio Calculators
Casio Computer Co., Ltd. was founded by the four Kashio brothers (Tadao, Toshio, Kazuo, and Yukio) in 1957. That same year, the company, in efforts led by the second-eldest brother Toshio, developed the “14-A,” which was the world’s first compact all-electric calculator, meaning that it ran only on electric circuits rather than using gears or motors.
Thereafter, the four brothers combined their respective strengths to grow the business while putting into the practice their ideals of “creativity and contribution.” Counting from the year 1965, the year 2025 marks the 60th anniversary of when the company launched the “001,” the first electronic desktop calculator with memory functions. Let’s look back on this long and storied history.
001
World’s First: Onboard Memory Functions
This model was the beginning of Casio’s electronic desktop calculator line. Its memory functions made a wide variety of calculations more efficient. The 001 marked the beginning of a new era of calculators.
101P
World’s First Onboard Recordkeeping (Printer) Functions
The 101P was capable of printing values and the results of calculations onto a roll of paper, allowing users to check the information later or keep records. This contributed greatly to more efficient work operations and accounting.
"fx-1"
The First “Scientific Calculator”
This model supported the calculation of 16 types of functions, including trigonometry, logarithms, and cube roots, all accessible from one-touch key operations. The fx-1 was the first in Casio’s revolutionary scientific calculator line.
CASIO Mini
World's First: Personal, Compact Calculator
The Casio Mini is notable for changing the concept of a calculator from a piece of office equipment to an everyday household item. It shocked the industry when it debuted at just one-fourth the size and one-third the price (at ¥12,800 [JPY]) of the mainstream models of the time.
JS-20
Origin of the Standard Business Calculator Series
The JS-20 was a solar-powered model at the perfect size for use either on a desktop or in the hands. Its design focused extensively on ease of use and practicality, and contained a wide variety of calculator functions required for business.
SL-800
World’s Thinnest Calculator in a Credit Card Size
Using a film-like approach to the electronic components, the SL-800 achieved a thickness of just 0.8 mm and a weight of 12 grams. This model combined the imagination and technical skills of Japan and was considered to be the ultimate in portable calculators.
fx-7000G
World’s First: Calculator with Onboard Graphing Functions
The fx-7000G made it easy to display graphs merely by entering a formula, where graphs previously had to be drawn by hand. This model contributed to mathematics education in the United States.
gx-CG1020
High-Resolution Color Display
This model sought to build interest in mathematics through, for example, analyzing a photo showing the lines drawn by water in a fountain and then generating a function to describe the phenomenon. It was helpful in supporting learning by reinforcing visual understanding through the use of colors for numerical values and graphs.
Origin of the ClassWiz − EX Series −
Country-Specific and Language-Related Functionality
The ClassWiz Series aligned with the school curricula in various countries via changes in functionality and language according to the country of use. This series is a collection of standard scientific calculators.
S100X
Reliability That Comes from Being Made in Japan
The S100X was designed as the flagship Casio calculator, favorably combining technology and the company’s reputation in a high-quality and easy-to-use model. It has been a popular option as a gift.
Ergonomic Calculators
Pursuit of Ergonomics in Calculator Design
The Ergonomic Calculators were created in consideration of ergonomic principles for the vertical pressing of the keys, with the calculator’s operable surface slanting at an incline of three degrees to align with the shape of the hand. With this design, the Ergonomic Calculators indeed offer a new “angle” in its approach to the pressing of keys.
These Calculators Are Actually Real!
