Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
245 words
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.
Claim 2
Dependent Claim
245 words
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.
Claim 3
Dependent Claim
63 words
The input control system of claim 1 wherein said first and second arrays of keys include first and second keyboard assemblies mounted in fixed position relative to one another on a common structural unit, an encoder on said unit, and a plurality of output conductors connected to said encoder for transmitting a binary coded signal to said controller when a key is actuated.
Claim 4
Dependent Claim
43 words
The input control system of claim 2 wherein said structural unit is mounted for movement between a first position in which only said first keyboard assembly is operator accessible and a second position in which only said second keyboard assembly is operator accessible.
Claim 5
Dependent Claim
62 words
The input control system of claim 2 wherein said structural unit is mounted for movement between a first position in which only said first keyboard assembly is operator accessible and a second position in which only said second keyboard assembly is operator accessible, and further including latch means for locking said structural unit in both said first position and said second position.
Claim 6
Dependent Claim
79 words
The input control system of claim 4 wherein said instrument includes support structure that has an opening therein, and said structural unit is mounted for rotational movement in said opening between a first (upright) position in which only said first keyboard assembly is operator accessible and a second (inverted) position in which only said second keyboard assembly is operator accessible, said latch means cooperating with said support structure for locking said structural unit in said first and second positions.
Claim 7
Dependent Claim
49 words
The input control system of claim 5 or 1 wherein said emission source is of the plasma type and both of said key arrays permit an operator to ignite said source for excitation of sample materials to spectroemissive condition and to run spectrochemical analysis sequences with said analysis unit.
