ABSTRACT:
An electronic apparatus having an optical communication capability of the present invention has a casing 10 and optical filters 12 and 13 for screening an infrared beam emitting/receiving device 25. The optical filters 12 and 13 each has a particular screening characteristic. The filters 12 and 13 are selectively removably fitted in a beam input/output window 11 formed in the casing 10. With these filters 12 and 13, it is possible to use one of the filters 12 and 13 matching the varying environment, and therefore to intercept optical noise lying in a broad wavelength range.
