Abstract

PROBLEM TO BE SOLVED: To simplify insertion/draw out of a board by providing protrusions to be inserted into the holes in an insertion/draw out chassis and in the vicinity of the upper or lower end of the board and using a card plaunit as an inserting/ drawing tool. SOLUTION: When a board 102 is inserted into the housing of an electronic apparatus, the protrusion 106a of a card plaunit 106 is inserted into a hole 102b in the vicinity of the upper end of the board and turned. Consequently, the face 106b of the card plaunit 106 abuts against the face 105c of an upper chassis 105a and, at the same time, the protrusion 106a of another card plaunit 106 is inserted into a hole in the vicinity of the lower end of the board 102 and turned. The board 2 can thereby be inserted into the housing of an electronic apparatus by abutting the face 106b of the card plaunit 106 against the face of a lower chassis. Consequently, the structure of chassis can be simplified and the board can be inserted/drawn out extremely easily without causing any burden on an operator.
