Modular input device system

Claim 2

A plurality of peripheral units adapted for electrical and mechanical interconnection, each peripheral unit comprising: (a) a housing; (b) a set of lugs mounted on one lateral side of said housing, each of said lugs having a pair of vertically spaced apart "C" shaped sections; (c) a set of "T" shaped tongue portions secured to a slide mounted on the opposite lateral side of said housing for engaging lugs on an adjacent peripheral unit; (d) first and second electrical receptacles mounted on opposite lateral sides of said housing for electrically interconnecting with electrical receptacles of laterally adjacent peripheral units; and (e) pivotal support means for adjusting the elevation of the unit and means on opposite ends of said pivotal support means for nesting pivotal support means of adjacent peripheral units together when the units are electrically and mechanically interconnected.

Claim 3

A connection system for linking input devices to a computer terminal, comprising: (a) two or more computer terminal input devices positionable remote from the computer terminal, each input device being operable by a user for generating an input signal, each input device having a processor mounted thereto for receiving the input signal generated by the input device and for processing that signal into a coded input signal; (b) a bus segment mounted to each input device, each bus segment having an end receptacle formed on each end thereof for connecting the bus segment of one input device with the bus segment of another input device, each bus segment of a particular input device being connected to the processor that is mounted to that particular input device so that the connected bus segments receive and conduct therethrough the coded input signals of all the input devices to which the connected bus segments are mounted; (c) a cable receptacle attached to each bus segment between the end receptacles thereof; and (d) a single calbe interconnected between the computer terminal and one of the cable receptacles for transmitting to the terminal the coded input signals that are conducted through the connected bus segments.

Claim 4

A connection system for linking input devices to a computer terminal, comprising: (a) two or more computer terminal input devices positionable remote from the computer terminal, each input device being operable by a user for generating an input signal, each input device having a processor mounted thereto for receiving the input signal generated by the input device and for processing that signal into a coded input signal; (b) a bus segment mounted to each input device, each bus segment having an end receptacle formed on each end thereof for connecting the bus segment of one input device with the bus segment of another input device, each bus segment of a particular input device being connected to the processor that is mounted to that particular input device so that the connected bus segments receive and conduct therethrough the coded input signals of all the input devices to which the connected bus segments are mounted; (c) a cable receptacle attached to each bus segment between the end receptacles thereof; and (d) a single calbe interconnected between the computer terminal and one of the cable receptacles for transmitting to the terminal the coded input signals that are conducted through the connected bus segments.

Claim 5

The system of claim 2 further including device connect means for connecting two input devices, the device connect means comprising: (a) a set of lugs mounted on one side of each input device, each lug having a spaced-apart "C" shaped section; and (b) a set of "T" shaped tongue portions slidably mounted on the opposite side of each input device for engaging lugs on adjacent input devices whereby laterally adjacent input devices may be securely connected together.

Claim 6

The system of claim 2 wherein each bus segment includes a second cable receptacle attached thereto to permit connection between the bus segments of two input devices that are spaced apart from each other.

Claim 7

The system of claim 2 further including a controller connected to the computer terminal and programmed to receive the coded input signals and to control the sequence with which the coded input signals are conducted through the connected bus segments to the controller.
