Satolex Calcu-pen
The Satolex Calcu-pen is an arithmetic calculator with algebraic logic. It has 4 functions, 5 keys, and an LED (light-emitting diode) display typical of calculators of this era. The power source is 1.5V LR1 mercury cell. The calculator was manufactured in Japan.
The original 1975 LED Calcu-pen must have seemed like something out of a science fiction film when it first became available. Each key is in fact a rocker that has four different functions to save space. The Calcu-pen was packaged in the same way as a quality fountain pen or ball-point pen and supplied in a plastic case with a spare ink refill.

Replacements:
If you have a Satolex Calcu-pen that is no longer working, you can first try replacing the 1.5V LR1 mercury cell. If that doesn't solve the problem, then you can consider replacing the calculator with a modern equivalent.
