Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a guide rail for holding a logic card used in an electronic device.

[Conventional technology]

Conventionally, as a guide rail 1 for holding a logic card used in an electronic device, there is one as shown in FIG. 3, for example.

The guide rail 1 for holding the logic card shown in FIG.
Has a width corresponding to the width of the logic card 2 and one groove 3 matching the thickness of the logic card 2.

[Problems to be solved by the device]

However, when a plurality of logic cards having different board thicknesses are mixed as the logic cards used in the electronic device, in order to use the conventional guardrail 1 described above, the logic card having the plurality of board thicknesses is adjusted to the respective board thicknesses. It was necessary to prepare a guide rail having a groove for each logical card, and determine and use a guide rail to be used for each logical card.

Also, after mounting the logic card on the electronic device once and then changing the mounting of the logic card to mount a logic card with a different thickness, the guide rails should be grooved according to the thickness of the logic card to be changed. There was a problem that it had to be replaced with a different width one by one.

The present invention has been made in view of the above-mentioned conventional problems,
To provide a guide rail for holding a logic card, which has a groove for holding a logic card used in an electronic device, and which can handle logic cards having a large number of types of board thicknesses. With the goal.

[Means for Solving the Problems]

A guide rail for holding a logic card having a groove for holding a logic card used in an electronic device according to the present invention is a cylinder having a plurality of grooves having different widths in a longitudinal direction in order to achieve the above-mentioned object. It is characterized in that it has a rotor of a shape and a support for rotatably supporting the rotor.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG.

The guide rail for holding the logic card of this embodiment includes a support base 10 fixed to the device and a rotor 11 pivotally supported by the support base 10.

The support bases 10 are a pair for attaching to an electronic device and each have an inverted L-shaped cross section, and grooves 12 for holding the logic card 2 are formed at the beginning of each tail.

The rotor 11 attached to the support 10 is rotatable about an attachment shaft 13 attached to the support 10. The rotor 11 has a plurality of grooves 14 to 17 around the outer peripheral surface thereof, and the grooves 14 to 17 have different widths. Of course, the depths of the grooves 14 to 17 are the same as the depths of the grooves 12 of the support base 10, and if the groove bottoms of the grooves 14 to 17 are aligned with the groove bottoms of the groove 12 of the support base 10, then The center lines of the groove 14 and the groove 12 of the support base 10 coincide with each other so that the logic card 2 can be smoothly received and held.

That is, when a plurality of logic cards with different thicknesses are mixed as the logic cards used in the electronic device, or when the logic card is mounted once in the electronic device and the logic card is changed in mounting, the logic cards having different thicknesses are mounted. In that case, the rotor 11 is rotated according to the thickness of the logic card to be mounted, and any one of the grooves 14 to 17 is selected to make the optimum groove correspond to the logic card.

[Effect of device]

As described above, the present invention provides a guide rail for holding a logic card, which has a groove for holding a logic card used in an electronic device, and a cylindrical rotor having a plurality of grooves having different widths in the longitudinal direction. Since the rotor is rotatably supported, the rotor having a plurality of different grooves in the longitudinal direction is rotationally moved around the axis of the support to match the width of the logic card. There is an effect that the optimum groove width can be freely selected and the guide rail can be provided without replacing the guide rail itself.
