Abstract: A sliding cover includes an outside plate, a structural member fixed to the rear face of the outside plate, a movable holding member disposed between the outside plate and the structural member, and a toggle disposed between the holding member and the outside plate or the structural member. The holding member includes two parallel racks and guiding portions disposed at both end portions and extending in the same direction as the racks. The holding member includes a holding plate; an even number of pinions meshed with each other and supported by the holding plate so as to be rotatable; and guiding components supported by the holding plate. The pinions, disposed between the guiding components, are meshed with the racks, and the guiding components are engaged with the guiding portions so as to be slidable. The biasing direction in which the toggle biases the holding member is reversed substantially at the midpoint of the movable range of the holding member.

Abstract: An electronic apparatus is provided. A component part containing chamber provided in the inside of a case constituting an armor of an electronic apparatus is so configured that a rectangular plate-like battery can be mounted and dismounted via a rectangular first opening opened in the lower surface of the case. One side wall in the vicinity of the first opening is provided with a second opening, and a component part containing space communicated with the second opening is provided in the inside of the case. A holder is provided which includes a first plate portion detachably attached to the second opening to shut off the second opening, and a second plate portion projecting from the first plate portion and extending in the component part containing space in the condition where the first plate portion shuts off the second opening, and a separable body is contained in the component containing space together with the holder.

Abstract: A sliding cover 30 includes an outside plate 70, a structural member 80 fixed to the rear face of the outside plate, a movable holding member 90 disposed in a space between the outside plate and the structural member, and toggling means 100 disposed between the holding member and the outside plate or the structural member. The holding member includes two parallel racks 82a and 82b, and guiding portions 81 disposed at both end portions and extending in the same direction as the racks. The holding member includes a holding plate 91; an even number of pinions 92a and 92b meshed with each other and supported by the holding plate so as to be rotatable; and guiding components 93 supported by the holding plate, the even number of pinions being disposed between the guiding components. The pinions located at both ends are meshed with the racks, and the guiding components are engaged with the guiding portions so as to be slidable.
