<P>PROBLEM TO BE SOLVED: To absorb a shock a board unit receives when the board unit hits with a backboard on its insertion. <P>SOLUTION: A card lever 31 (an insertion boosting means) is engaged with a front frame 11a of a shelf 11 at a point in front of a complete insertion point for a line card 21 to form a fulcrum of the lever on the front frame 11a. A user applies a pressure to a lever arm 311 to transmit the pressure to the line card 21 through a point of load against the fulcrum, so that the line card 21 is inserted into the complete insertion point. A leaf spring member 41 (a shock-absorbing means) contacts with the front frame 11a of the self 11 at a point within a depth D of a front panel 213 of the line card 21, and the point is in front of an operation start point at which the card lever 31 is engaged with the front frame 11a of the shelf 11, so that a shock received by the line card 21 on its insertion is absorbed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
