  • Keyboard type of input control system for an analytical instrument
    Patent number: 4330776
    Abstract: An input control includes first and second keyboard assemblies mounted on a common structural unit, an encoder on the unit, and a plurality of output conductors connected to the encoder for transmitting a binary coded signal when a key is actuated. The first keyboard assembly includes a set of keys that generate the same input control function signals as do the keys in the second keyboard assembly. The structural unit is mounted for rotation between an upright position in which only the first keyboard assembly is operator accessible and an inverted position in which only the second keyboard assembly is operator accessible. A latch is provided for locking the structural unit in either position.
