POSITIONING STRUCTURE OF ELECTRONIC CIRCUIT SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To prevent a parts mounting area from being narrowed and reduce a manufacturing cost by making positioning dowels which require to be screwed to each electronic circuit substrates unnecessary. SOLUTION: When the electronic circuit substrate 1 is laid and put on guiding and supporting members 4a, 4b to mount while inserting the same into a shelf 3, the connector 2 of the electronic circuit substrate 1 is engaged with the positioning hole 6 of a rear plate 5 to effect the positioning of the substrate 1 in the left-and-right direction of the same while the tip end side of the electronic circuit substrate 1 is engaged with the notch 8 of a positioning plate 7 to effect the positioning of the electronic circuit substrate 1 in the up-and-down direction of the same.
