Information processing device

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.

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 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.
