Claim:
An information processing apparatus comprising: a chassis being shaped into a rectangular parallelepiped having six faces of a top face, a bottom face, a first pair of opposing side faces, and a second pair of opposing side faces and including an opening portion in a certain one of the first pair of opposing side faces; a first holder being arranged at a first accommodation position in the chassis and holding a predetermined electrical component that freely reciprocates on a first transfer pathway connecting the first accommodation position and the opening portion; a second holder including the first transfer pathway in the chassis, being arranged at a second accommodation position farther than the first accommodation position from the opening portion, and holding a predetermined electrical component that freely reciprocates on a second transfer pathway connecting the second accommodation position and the opening portion; a rotating member being rotatable around a certain point at an upper end portion of the opening portion in a plane parallel to a certain one of the second pair of opposing side faces from a first rotational position at which the entire rotating member is accommodated in the chassis to a second rotational position which the rotating member reaches when the rotating member is rotated by a certain angle of 90 degrees or more; a first-holder/rotating-member fixing unit fixing the first holder to the rotating member remaining stationary at the first rotational position, when the first holder is moved from the first accommodation position to a predetermined position that the first holder reaches before completely passing through the opening portion; and a releasing unit releasing, under a predetermined condition, the first holder and the rotating member secured by the first-holder/rotating-member fixing unit.
