はりコスト高となる欠点があつた。 Conventionally, this type of device includes a long mounting member or a printed circuit board on both sides of which a fixed contact is provided at a position opposite to the movable contact of each movable contact member that is pressed and driven by the actuator of each keyboard. For example, it has been proposed to attach the keyboard to a keyboard support board via multiple attachment members, but the method using long attachment members requires a large amount of material, resulting in high costs, and requires multiple attachments. Although the material cost of the keyboard using components is low, it takes time and effort to attach the printed circuit board to the keyboard support board, which also increases the cost.

決定する。 In the drawing, the movable contact member 3 is made of a flexible material such as rubber or synthetic resin, and has a tubular upper part and a bowl-shaped lower part, and the bottom of the bowl-shaped part is made of conductive rubber or other conductive material. A movable contact 3a is provided integrally with the movable contact member 3 or by adhesive. This movable member 3 has a plurality of keyboards integrally formed through a common plate 8, and this common plate 8 is fixed to the printed circuit board 5. When a plurality of pieces 6b are molded by injecting a material such as synthetic resin or aluminum into one mold, the mounting member 6 is filled into a runner that connects the spaces between the pieces 6b of the mold. synthetic resin etc., i.e. runner 6
A is left as is without cutting it out. Therefore, the length of the runner between the cavities for the mold parts 6b is set to a length suitable for attaching the printed circuit board 5 to, for example, a board 7 for supporting a keyboard, as shown in FIGS. 1 and 2. Manufacture the molds so that they are L and L'. The number of members 6b connected by the runners 6a is determined in consideration of ease of handling and mechanical strength.

て材料費を低減できる効果がある。 When attaching the printed circuit board 5 to the circuit board 7 via the mounting member 6 by screwing the mounting screw 9 into the hole 7a of the circuit board 7 through the hole 5a of the printed circuit board 5 and the hole 6b-1 of the piece 6b. To facilitate this, a protrusion 6b-2 is provided on the upper surface of the piece 6b of the mounting member 6 as shown in the third diagram, and the mounting screw hole 7a of the board 7 and the mounting screw insertion hole of the piece 6b are provided on the board 7. 6b
-1 are aligned, holes 7b, 7b are made at a position where the projection 6b-2 can be inserted, and the projection 6b-2
The mounting member 6 can be temporarily fixed to the substrate 7 by fitting the piece 6 into the hole 7b, or vice versa.
A protrusion 6b-2 is provided on the lower surface of the printed circuit board 5.
Then, with the hole 6b-1 of the piece 6b and the mounting screw hole 5a of the printed circuit board 5 aligned, the projection 6b is
Holes 5b, 5b are made at positions where the parts 6b-2 and 6b can be fitted into the holes 5b, 5b, and the protrusions 6b-2, 6b of the piece 6b are inserted into the holes 5b, 5b.
-2, the mounting member 6 is temporarily fixed to the printed circuit board 5, or the mounting member 6 is adhered to the board 7 or the printed circuit board 5, and then the printed circuit board 5 or the mounting member 6 and the printed circuit board 5 are attached to the board. Attach to the side using mounting screws 9. In this way, according to the present invention, a plurality of pieces connected to each other by a runner during molding are used as a mounting member for attaching a printed circuit board provided with fixed contacts to a board for supporting a keyboard, etc. Therefore, there is no need to install multiple separated parts one by one between the board and the printed circuit board, and there is no need to remove the runner during molding, which reduces man-hours and costs. This also has the effect of reducing material costs compared to a long rod-shaped mounting member.
