Casio DE-12E-WE

Desktop calculator DE-12E-WE

Ergonomically designed for right-handed users: The keyboard is configured in an innovative staircase design with a 3° slope from right to left. Compared to conventional desktop calculators, this innovative keyboard design causes less torsion of the forearm and rotation of the wrist as it adapts to the natural finger and hand position. The stair-step key shape allows for perfect vertical keystrokes, making typing easier, reducing strain and helping to prevent repetitive strain injuries (RSI). This reduces the muscle activity of these 3 muscles: Musculus pronator teres, Musculus extensor carpi radialis and Musculus flexor carpi radialis.
