Abstract

PURPOSE:To display an ambient humidity on an electronic desktop calculator, by converting the humidity value to an electric signal to display it on a display equipment. CONSTITUTION:The light from an irradiation lamp 16 has the quantity limited in accordance with the humidity detected in a humidity sensing part 14 and is detected by a photodetector 23. The output of the photodetector 23 is amplified by a voltage amplifier 31 and is converted to a digital signal by an A//D converter 32. This digital signal is decoded by a decoder 33 and is inputted to a key signal converting circuit 34. The key signal converting circuit 34 converts the signal outputted from the decoder 33 to a signal corresponding to the key signal outputted from a key input part 35 for desk calculator, and this converted signal is inputted to a desktop calculator input circuit part 36. When a changeover switch 24 is set to the position of HYGRO, the humidity of the outside is displayed on a display part 5; and when this switch 24 is set to the position of COMP, numeric information as a desk top calculator is displayed on the display part 5.
