Abstract

An information processing device includes: a case; a base member that includes an attachment hole and a positioning hole, and that is provided inside the case; a switch that is fixed to the base member; a button member that includes an operation button that moves toward and away from the switch; an anchor member that is provided at the button member, and that includes an insertion tab that is inserted into the attachment hole and a claw that projects out from a leading end side of the insertion tab and that is hooked onto an edge portion of the attachment hole; and a positioning protrusion that is provided at the button member, and that is inserted into the positioning hole, the positioning hole being formed in an elongated hole shape extending along a projection direction of the claw.

First claim

What is claimed is:

1. An information processing device, comprising:
a case;
a base member that includes an attachment hole and a positioning hole, and that is provided inside the case;
a switch that is fixed to the base member;
a button member that includes an operation button that moves toward and away from the switch;
an anchor member that is provided at the button member, and that includes an insertion tab that is inserted into the attachment hole and a claw that projects out from a leading end side of the insertion tab in a projection direction and that is hooked onto an edge portion of the attachment hole; and
a positioning protrusion that is provided at the button member, and that is inserted into the positioning hole, the positioning hole being formed in an elongated hole shape, the longest dimension of the elongated hole extending along the projection direction of the claw.

2. The information processing device of claim 1 , wherein, in an inserted state of the positioning protrusion into the positioning hole, the positioning protrusion positions the button member with respect to the base member in a direction intersecting the projection direction of the claw.

3. The information processing device of claim 1 , wherein the positioning protrusion is disposed at an opposite side of the anchor member from the claw.

4. The information processing device of claim 1 , wherein:
the author member comprises a pair of anchor members disposed at an interval along a length direction of the button member;
the positioning protrusion comprises a pair of positioning protrusions disposed between the pair of author members;
the pair of anchor members are disposed in a state in which the respective claws face toward opposite sides from each other; and
the pair of positioning protrusions are respectively inserted into a pair of the positioning holes formed in the base member.

5. The information processing device of claim 4 , wherein the pair of positioning holes are formed in elongated hole shapes extending along a length direction of the button member.

6. The information processing device of claim 4 , wherein the pair of anchor members are provided at end portions at respective length direction sides of the button member.

7. An information processing device, comprising:
a case;
a base member that includes attachment holes, a pair of first positioning holes and a second positioning hole, and that is provided inside the case;
a switch that is fixed to the base member;
a button member that includes an operation button that moves toward and away from the switch;
a pair of first anchor members and a second anchor member that are each provided at the button member, and that each includes an insertion tab that is inserted into one of the attachment holes and a claw that projects out from a leading end side of the insertion tab in a projection direction and that is hooked onto an edge portion of one of the attachment holes; and
a pair of first positioning protrusions and a second positioning protrusion that are each provided at the button member; and that are respectively inserted into the pair of first positioning holes and the second positioning hole, wherein:
the pair of first anchor members are disposed at an interval along a length direction of the button member and are disposed in a state in which the respective claws face toward opposite sides from each other,
the pair of first positioning protrusions are disposed between the pair of first anchor members and are respectively disposed in the vicinity of the pair of first anchor members,
the claw of the second anchor member projects out in a direction intersecting a projection direction of the claws of the pair of first anchor members as viewed along a thickness direction of the button member,
the second positioning protrusion is disposed in the vicinity of the second anchor member, and
the pair of first positioning holes are each formed in an elongated hole shape the longest dimension of the elongated hole extending along the projection direction of the claw of the first anchor member, and
the second positioning hole formed in an elongated hole shape, the longest dimension of the elongated hole extending along a direction perpendicular to the projection direction of the claw of the first anchor member.

8. The information processing device of claim 7 , wherein the pair of first positioning protrusions and the second positioning protrusion are disposed along a straight line.

9. The information processing device of claim 7 , wherein the second positioning hole is formed in an elongated hole shape extending along a transverse direction of the button member.

10. The information processing device of claim 7 , wherein:
in a state in which the first positioning protrusions are inserted into the first positioning holes, the first positioning protrusions position the button member with respect to the base member in a transverse direction of the button member, and
in a state in which the second positioning protrusion is inserted into the second positioning hole, the second positioning protrusion positions the button member with respect to the base member in the length direction of the button member.

11. The information processing device of claim 7 , wherein the second anchor member and the second positioning protrusion are disposed in a row along a transverse direction of the button member at a central portion in the length direction of the button member.

12. The information processing device of claim 11 , wherein the second anchor member is provided at an end portion at the central portion of the button member.

13. The information processing device of claim 1 , wherein:
the button member includes a button base, and a connector arm that connects the button base and the operation button together and that moves the operation button toward and away from the switch in conjunction with elastic deformation of the connector arm; and
the anchor member and the positioning protrusion are provided at the button base.

14. The information processing device of claim 1 , wherein:
the switch comprises a pair of switches that are disposed at an interval along a length direction of the base member and are fixed to the base member; and
the operation button comprises a pair of operation buttons that respectively move toward and away from the pair of switches.

15. The information processing device of claim 1 , further comprising a switch substrate that is fixed to the base member, wherein the switch is mounted to the switch substrate.

16. The information processing device of claim 1 , wherein the operation button comprises a click button.

17. The information processing device of claim 1 , wherein the switch comprises a tactile switch.

18. The information processing device of claim 1 , further comprising:
a main body device that includes the case; and
a display device that is coupled to the main body device so as to be capable of swinging.

19. A button unit, comprising:
a base member that includes an attachment hole and a positioning hole;
a switch that is fixed to the base member;
a button member that includes an operation button that moves toward and away from the switch;
an anchor member that is provided at the button member, and that includes an insertion tab that is inserted into the attachment hole and a claw that projects out from a leading end side of the insertion tab in a projection direction and that is hooked onto an edge portion of the attachment hole; and
a positioning protrus
