<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus which specifies a broken part caused by a load, when the load such as a shock is applied and which securely detects breakage of a substrate. <P>SOLUTION: By having a recess 11g formed inside a hole for inserting a screw fixing a slot unit 4 to the substrate 11, cracks are made to occurs preferentially in the recess 11g than for a hole, when a load such as the shock is applied to the slot unit 4 from the outside. Namely, the occurrence part of the crack can be specified. Thus, occurrence of the crack can be detected, without fail, and protection processing can be performed by forming a conductive pattern 12 in the vicinity of the recess 11g. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
