Abstract
A computer input device sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises a horizontal or vertical container dimensioned to fit over computer input devices such as keyboards, mice, trackballs, touchpads and the like. An ultraviolet source within the container irradiates the computer input device with UV light which, in one embodiment generates ozone gas, thereby killing any microorganisms that might reside on the computer input devices. Ultraviolet radiation below 200 nm can also be used thereby creating ozone gas having germicidal characteristics. The ozone gas is circulated in and around the input device thereby providing further sterilization together with the ultraviolet radiation. A sterilization switch turns the UV source off when the container is opened. A timer/power circuit provides the times application of power to the UV lamps to provide UV illumination consistent with the substantial sterilization of the input device in question.
