The stud 12a is moved to a position in contact with 13A. Thereby, the through hole 120 of the stud 12a is positioned on the hole 14A. After the stud 12a is positioned, the fixing bracket 12c is tightened to fix the positions of the stud guiding instrument 12b and the stud 12a. Next, the half-size Mini PCI-e card 10A is inserted into the Mini PCI-e slot 11, and the card fixing screw 12d is screwed into the hole 14A via the fixing hole 10a and the through hole 120 of the stud 12a, so that the half-size The mounting of the half-size Mini PCI-e card 10A is completed by fixing the Mini PCI-e card 10A.

  Further, when the full-size Mini PCI-e card 10B is inserted into the Mini PCI-e slot 11, the fixing bracket 12c for fixing the stud guiding instrument 12b is loosened before the insertion, and the stud guiding instrument 12b is used as a positioning pin. The stud 12a is moved to a position in contact with 13B. Thereby, the stud 12a is positioned on the hole 14B. After the stud 12a is positioned, the fixing bracket 12c is tightened to fix the positions of the stud guiding device 12b and the stud 12a. Next, the full-size Mini PCI-e card 10B is inserted into the Mini PCI-e slot 11, and the card fixing screw 12d is screwed into the hole 14B through the fixing hole 10a and the through hole 120 of the stud 12a, so that the full-size The mounting of the full-size Mini PCI-e card 10B is completed by fixing the Mini PCI-e card 10B.

(Effects of the first embodiment)
According to the first embodiment described above, the stud 12a and the fixing bracket 12c are attached to the stud 12a so as to be rotatable around the fixing bracket 12c on the substrate 15 and fixed by the positioning pins 13A or 13B. The stud 12a is positioned so that the hole 10a or the fixing 10b, the through hole 120, and the hole 14A or 14B coincide with each other, and the position of the stud 12a is fixed by the fixing metal 12c, so that the arrangement of the stud 12a is inserted into the Mini PCI-e slot 11. It can be easily changed according to the size, full size or half size of the Mini PCI-e card. Further, since the Mini PCI-e card is fixed by the card fixing screw 12d via the stud 12a, a fixed strength that is above a certain level can be easily achieved as compared with the stud clamped and fixed to the substrate.

  Moreover, since the process of fixing the stud on the hole with the conventional solder can be omitted, the production efficiency increases.

  Note that the slots and cards are not limited to those of the Mini PCI-e standard, and slots and cards of any standard can be used. Further, the expansion card may be fixed by a method other than screw fixing, such as fitting with another member or engaging the expansion card.

  In addition, the size of the expansion card mounted on the board | substrate 15 is not limited to two types, You may make it respond | correspond to multiple types of size. For example, in the present embodiment, two types of sizes are assumed in the longitudinal direction of the expansion card. However, the expansion having a wide size in the short direction can be achieved by fixing the stud 12a at an intermediate position with respect to the holes 14A and 14B. It can correspond to the installation of the card.
