(a) Field of the Invention
The present invention relates a peripheral with expansion connector attachable to a host, and more particularly, to one provided with input for dedicated interface circuit to couple to the host and an selection switch to switch between input contact and output connector.
(b) Description of the Prior Art
The prior art of a peripheral attachable to a computer host must be removed when connection to any other interface is required. To improve computer use convenience, the present invention of a peripheral is provided with additional expansion connector and a selection switch so to make connection with other interface for the host possible without removing the peripheral using the expansion connector.
The present invention relates to a peripheral provided with expansion connector attachable to a host and contains an interface connector (or a plug-socket unit) P1 to be connected to an interface connector (or a plug-socket unit) P0 from the host, a subsidiary I/O interface connector (or plug-socket unit) P2; a dedicated interface circuit C100 and an selection switch SL100 to conduct through said interface connector (or plug-socket unit) P1 either to said dedicated interface circuit C100 or the subsidiary I/O interface connector (or the plug-socket unit)P2.
