Sanyo Electronics Company (Japan) entered end of 1970 with the ICC-0081 (Integrated Circuit Calculator) the market of portable, electronic calculators. This "Mini Calculator" with rechargable NiCd batteries and an integrated AC-adapter lists in one line with:

Busicom LE-120 
Canon Pocketronic
Sharp QT-8D

Two later, somewhat smaller Sanyo calculators were manufactured for Dictaphone (USA) and known as Dictaphone 1680 (ICC-82D) and Dictaphone 1681 (ICC-804D).
