<p>An integrated mouse/trackball 31 is coupled via a transmission wire 311 to a receiver coupling socket interface 14 incorporated within a relay keyboard 1 which is coupled to a computer unit 2 by a transmission wire 12. The keyboard includes notches 102 on both sides of a bottom chassis 101 thereof which retain the mouse transmission wire 311. The transmission wire is coupled via a plug 312 to the interface 14 in the keyboard. A relay wire 13 feeds from the plug and runs in parallel with the keyboard transmission wire 12 to the computer. Alternatively, the transmission between the mouse/trackball and keyboard may be executed in a wireless mode (Fig.3), wherein the transmission therebetween is by infra-red/ultrasonic waves emitted from the mouse/trackball which are received on the keyboard by a receiver R0. Both arrangements permit coupling of the mouse in a position suitable for a left or right-handed user. The wired arrangement also minimises the length of transmission wire in use. Numerous other wireless arrangements are disclosed (Figs.3-19), in particular the various forms of receivers and also the manner in which the receiver may be coupled to the keyboard. Additionally, the wireless mouse may be battery powered and may be recharged by a socket (107,Fig.20) on an edge wall of a mouse pad 106.</p> |
