ABSTRACT:
An apparatus that dispenses disposable sanitary keyboard covers of a flexible transparent plastic film that is drawn across a key array and provides a sanitary cover that allows full use of the keyboard. When a subsequent user uses the keyboard, a new length of plastic film is drawn, and the old length of film is discarded. The apparatus includes a frame having a first tray holding a dispensing reel of plastic film at one end, and at the other end a second tray holding a take-up reel in a first embodiment, or rollers that direct the film to a slot in the outer wall of the tray with a cutting blade adjacent to the slot in a second embodiment.
