The cover is covered with the cover member 88102121. A cover plate is provided in a modified form, and the member and the cover member are engaged with the rotation. When the locking and guiding part of the elastically rotating locking mechanism is used, the lid is configured by the above-mentioned lock to float the locking member, and the closed end side of the lid is from the card, toward and will release the above When the cover structure is operated to make the state, the member releases the rotating body, and at the opening portion, the surface fixing member is usually provided with the rotating body with a rotating guide for opening the opening direction to open and close the opening.: Even member rotation member fixed member falling into the opening and closing operation of the opening member Solutions π rotation of the engagement portion engaging the guide member square 'also engages. The cover opening member of the piece and the engagement are turned along with the rotation of the axis of the rotating body and intersect with the axis of rotation and in the other direction, and will be guided relative to the above engagement at the upper position. The abutment is moved to the sliding surface that engages and slides to the position where the locking structure is opened, that is, the cover is closed to the cover plate of the closed structure, and the sliding guide cover is closed due to resistance. The “locking” is to lock the rotating body in a state where the direction of the cover is transduced to the direction of the axis of rotation, and the cover structure is locked to the above surface that will not be disengaged from the operation when the engagement is maintained, and the above-mentioned resistance against the opening is stored. Composition of potential elastic surface. The member resists the movement, thereby causing the surface of the moving body to fall and the engaging member to be closed from the axis of rotation of the member to the closing position of the resistive opening closing position < set to rotate in conjunction with the case, also 552231 case number 88102121. July + Revision V. Description of the invention (6) The cover member linked to the rotating body will not move with the engagement and disengagement operation, and even if the cover plate is pressed by mistake or an object is placed on the cover plate When the rotating body is rotated unexpectedly, the cover member can be prevented from being opened due to the position of the locking member that can be engaged with the engaging and guiding surface. The opening and closing structure of the cover member of the invention of claim 2 is in the opening and closing structure of the cover member of the invention of claim 1 in the above patent application. The cover member is rotated in conjunction with the rotation of the cover member provided with the cover to be opened. The rotating body is configured to include a contact portion that abuts against the stopper means at the open position of the cover. The opening and closing structure of the cover member thus constructed is to open the cover member from the closed position of the opening due to the accumulating elastic pressure #, and to abut the abutment portion of the rotating body connected to the cover member to the provided stopper. Keep it in the open state. The opening and closing structure of the cover member of the invention in the third scope of the patent application is the opening and closing structure of the cover member of the invention in the first or the second scope of the above patent application. The rotating form is assembled on both sides opposite to the opening, and at the same time, the opening is closed by closing the cover plate of the cover member, and the opening is opened by opening the cover plate. The opening and closing structure of the lid member thus constituted allows a pair of lid members to be assembled in the closed position of the opening without providing a gap between the respective front end sides. [Embodiment of the invention] Hereinafter, the opening and closing structure of the cover member according to the exemplary embodiment of the present invention will be described in detail.
