This is a SHARP electronic dictionary. It's a calculator from the Showa era. It represents the pinnacle of SHARP's technological prowess at the time of its release. For those tired of today's overly convenient searches, this is a supreme device that allows you to savor the inconvenience. ＜Functions include the following three＞ Calculation, English-Japanese, Japanese-English... Please do not compare it to Google search. Operation has been confirmed. New batteries are also included. ※For battery replacement, please prepare three button batteries (LR-44). The characters will appear faint if all three batteries are not new (this is the original specification, not a deterioration). The cover's body fixing part (transparent vinyl part) and the instruction manual are deteriorated as shown in the photos, but are included. The main body is clean. Thank you.
