And setting the substrate storage width by inserting the substrate into the substrate storage magazine.

[0010]

In order to set and adjust the substrate storage width by using the jig for determining the width of the substrate storage magazine according to the above configuration, the side of the width plate portion is held at one side of the substrate storage magazine by holding the column. It is to be inserted into each storage groove of the side plate (5).
Then, the side plate 7 is fixed to the top plate 3 and the bottom plate 1 at a position where the other side of the width plate portion is settled in the corresponding storage groove of the other side plate (7) and abuts against the bottom of each storage groove. It is fixed by screws 19a, 19b and 21a and 21b. Thereafter, the setting adjustment of the substrate storage width is completed by pulling out the width determining jig from the magazine.

In such a jig for determining the width of the board storage magazine, since a plurality of width plate portions are fixed in parallel to each other by the support portions, the side of each width plate portion is inserted into the board storage groove of the magazine. It can be easily inserted and fixed, and the work of setting the storage width is performed very easily. Further, since the width plate portion has a width obtained by adding a predetermined margin to the width of the accommodated substrate, it is possible to set and adjust the desired accommodation width accurately and accurately.
That is, even if the operator is not particularly skilled, it is possible to very easily and accurately set and adjust the board storage width.
