INPUT/OUTPUT SWITCHING DEVICE

摘要

PURPOSE:To arrange the input/output terminal to a front panel without increase in the circuit scale and cost by arranging the input/output terminal to a rear panel and a front panel respectively and providing a switching means switching each input signal. CONSTITUTION:Input terminals 1-4 and output terminals 11-14 are provided on the rear panel 6 and an input terminal 5 and an output terminal 15 are arranged respectively to the front panel 7. Input select switches 21-24 are switched by a switch control signal generated from a switch controller 25 by the operation of a panel switch 8. Thus, a signal from terminals 1-4, 4 or 5 of the switches 21-24 is outputted selectively. The output of the switches 21-23 is outputted from output terminals 11-13 respectively via output switches 31-33. The output of the switch 24 is taken out from the output terminal 14 via the output switch 34 and the buffer 35 and from the output terminal 15 via the buffer 36 respectively.
