Claims

[Claims for Utility Model Registration] Printed boards 10 having individual front plates 11 are inserted in parallel to the shelf 1, and the parallel individual front plates 11 allow air to flow through the opening of the shelf 1. In the printed board device configured to block the front panel, there is provided a main plate member 21 made of an elastic material that has substantially the same shape as the individual front plate 11 when viewed from the front, and a lower edge of the shelf front frame 2 on the back surface of the main plate member 21. A lower locking pawl 22 formed to face the shelf front frame 2; An individual front cover 20 is provided with a positioning protrusion 24 formed on the back surface of the main plate member 21 and an insertion hole 25 bored in the main plate member 21 so as to be inserted into the notches 3 parallel to the side edge. The lower locking claw 22 and the upper locking claw 23 engage with respective corresponding side edges of the shelf front frame 2, so that the opening of the shelf front frame 2 where the printed board is not mounted is closed. An air-blocking structure with a shelf opening, characterized in that the individual front covers 20 are installed in parallel on the front surface.
