Keyboard type of input control system for an analytical instrument
First Claim
1. An input control system for an analytical instrument that includes a spectroanalysis system having an emission source optically coupled to an analysis unit, comprising a controller that provides outputs to control an analysis sequence of said emission source and said analysis unit, an input control unit coupled to said controller, said input control unit having first and second arrays of keys, said first array of keys including a first set of keys that provides a first group of input control functions that permit an operator to run an analysis sequence provided by said controller for said emission source and said analysis unit, and a second set of keys that provides a second group of input control functions that permit an operator to vary the analysis sequence provided by said controller for said emission source and said analysis unit, said second array of keys providing the same input control functions as said first group of input control functions but not said second group of input control functions such that an operator is permitted to run, but not to vary, an analysis sequence provided by said controller for said emission source and said analysis unit, said second array including a set of keys that duplicate said first set of keys in said first array, and movable means having a first condition in which only said first array of keys is operator accessible and a second condition in which only said second array of keys is operator accessible.

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.
