Claims (1)

[Scope of Claim for Utility Model Registration] A case body having a top wall and a bottom wall and forming an opening in the front, and an inner door piece each rotatably connected to the case body via a shaft. and an outer door piece connected to the inner door piece so as to be foldable inward, a pair of door bodies capable of opening and closing the front opening of the case body, and one end of which can be rotated onto the outer door piece. a pair of operating means, the other end of which is rotatably connected to the top wall or bottom wall of the case body via a rotation shaft; A pair of guide grooves are formed in the wall to receive the rotation shaft and guide the rotation shaft so that the rotation shaft moves in accordance with the opening and closing movement of the pair of door bodies. , further comprising a biasing means for biasing the rotation shaft to move from one end side of the guide groove toward the other end side, and a biasing means formed on a top wall or a bottom wall of the case body,
a guide wall that comes into contact with the tip end edge of the outer door piece in a predetermined range of the opening/closing operation of the pair of door bodies and guides movement of the tip edge; and a guide wall connected to the pair of door bodies. and an electric motor for opening and closing the pair of door bodies, and the pair of operating rod means, the guide groove, and the guide wall are configured to achieve the following operations, namely: In the closed state of the door, The rotation shaft is located at one end of the guide groove, and the leading edge of the outer door piece is in contact with the guide wall, and in an intermediate state on the way from the closed door state to the open door state, the rotation The shaft is located at the other end of the guide groove, and the tip side edge of the outer door piece is in contact with the guide wall, and from the closed door state to the intermediate state,
The rotation shaft moves from one end of the guide groove toward the other end, and the leading end edge of the outer door piece moves linearly while abutting the guide wall, so that the intermediate state changes from the intermediate state to the open state. Until then,
The rotating shaft remains located at the other end of the guide groove, and the outer door piece rotates while increasing the angle formed between the outer door piece and the inner door piece.
