PROBLEM TO BE SOLVED: To provide a mechanism capable of detecting whether a print circuit board is properly inserted at the initial stage of insertion into a shelf.SOLUTION: The mechanism includes: a stopper component having a cut-out, which is attached to a print circuit board at the engagement connector side of a backboard; and a projection formed on the shelf. By determining whether the projection formed on the shelf passes through the cut-out formed on the stopper component attached to the print circuit board when inserting the print circuit board into the shelf, the mechanism detects whether a print circuit board is inserted properly at an initial stage of insertion of the print circuit board.SELECTED DRAWING: Figure 5 |
