<p>PROBLEM TO BE SOLVED: To prevent any malfunction of an electronic circuit even when a substrate is erroneously inserted by allowing a controller to refer to an inserted and extracted state storing means, and to operate control corresponding to the referred result at the time of detecting any failure in access to the substrate, or in a preliminarily specified timing. SOLUTION: A reset control circuit 16 on which a hard disk being an inserted and extracted state storing means for operating an initial program load connected with a male contact 17A of an ID2 is loaded monitors whether or not the ID2 being the ID of a substrate 13 side is made coincident with an ID1 being the ID of a connector 15 side. Then, when the ID2 is not made coincide with the ID1, the reset control circuit 16 refers to an inserted and extracted state stored in the hard disk, and judges that the insertion is erroneous insertion according to the referred result, and obtains a reset state for preventing any access from being performed to the substrate 13. Thus, the malfunction of the electronic circuit can be prevented.</p> |
