Abstract

PROBLEM TO BE SOLVED: To prevent the shape of a back board from being affected by the number of interfaces by providing a housing slot which shares a pin of a slot at both sides on the rear surface of the back board, to enable a sub-board mounted with an interface to be inserted into and drawn from the housing slot. SOLUTION: A backboard comprises a back board substrate, a slot 212, a housing slot 213, and an instrument 214 for fixing an interface sub-board, and has a slot connector pin 215 which is shared with the slot 212 and the housing slot 213. By pin assignments of a connector 222 on an interface board substrate 221 and a connector 232 on a sub-board substrate 231, prescribed pins of an interface IC 233a on the interface board are connected to the prescribed pins of an interface connector 234a on the sub-board. Also, prescribed pins of an interface connector 234b on the interface board are connected and can be made to function as an interface connector on the sub-board.
