Characterized in that it comprises a fixing means for releasing the fixing of the lid when it is.

  According to the first aspect, since the space for the second arm portion to slide is not required between the case main body and the case lid, the space occupied by the second arm portion can be minimized. it can. Thereby, space saving between a case main body and a case cover can be achieved, and the storage case can be reduced in size.

  The storage case according to a second aspect of the present invention is characterized in that, in the first aspect, the through hole has an elongated hole shape extending substantially parallel to a sliding direction in which the lid slides.

  The storage case according to a third aspect of the present invention is characterized in that, in the second aspect, the end of the second arm portion is bent substantially perpendicular to the longitudinal direction of the through hole. And

  An electronic device according to a fourth aspect of the present invention further includes a storage case according to the first to third aspects, and a ground member provided outside the case body and grounded, The end of the arm is in contact with the ground member.

  According to the fourth aspect, the countermeasure against static electricity is implemented by bringing the second arm portion into contact with the conductive ground member (shield member) normally provided in the interior of the casing of the electronic device. As a result, countermeasures against static electricity can be implemented without adding new parts. Thereby, further miniaturization of a storage case can be achieved.

  A storage case according to a fifth aspect of the present invention includes a case body including a storage portion for storing storage items, and an opening for taking the storage items in and out of the storage portion, and a predetermined rotation. A lid that is pivotably attached around an axis, is slidably attached to the case body, a standing wall formed at the periphery of the opening, and the lid is in a first position.
