Definitions
- positions of the sheet identify alphanumeric characters, and the manual input of a character is made by causing an impact at the appropriate position. This may be done simply by tapping the sheet with the finger, but preferably some form of mechani'sm is provided for better accuracy and uniformity.
- Such mechanism may comprise typewriter- style keys, or 'a bubble film.
- the sheet is preferably glass, but other materials of low acoustic absorption and good mechanical stability may be used.
- the reference signal means may suitably comprise a continuous conductive coating on one side of the sheet, and means carried by the keys or the like for closing an electrical circuit at the same time as causing an impact on the sheet. A metal of suitable acoustic properties may be used, in which case no conductive coating will be required.
- the timing reference signal could be generated acoustically rather than electrically, by forming an acoustic transducer over the whole of the undersurface of
