An electronic device includes: a first housing; a covercapable of covering a portion of the first housingto be covered; and a waterproofing memberplaced around the portion to be covered. The coveris displaceable between a closed position at which the cover covers the portion to be covered and an open position at which the cover opens the portion to be covered. The coveris in contact with the waterproofing memberwhen it is at the closed position. Even if the number of terminals increases, since the waterproofing memberis provided on the first housing, the single waterproofing member can render all of the terminals waterproof. Thus, it is possible to reduce the number of components and to reduce the number of assembling steps.

Electronic device provided with cover

A casing, a lid componentfor covering a terminaldisposed in an opening of the casing, and a water sealing componentdisposed around the terminal, are provided. The lid componentis structured such that a support portionof a fixing portionis rotatably fixed to the casing, and a slidable portionslides relative to a lid portion. Thus, a projectionis engaged with a recess, and a pair of engagement portionsengages with a pair of fixed projections. Thus, the lid componentengages with the casingin three directions, and is held by being pressed against the water sealing component. With this structure, an electronic device having a lid component which can be assuredly locked is obtained.

Electronic device

A casing, a terminal platethat is exchangeably mountable in an openingformed in the casing; and a water sealing componentdisposed around a terminalformed on the terminal plate, are provided. A flangeis formed inside the openingso as to surround a center of the opening and project toward the center of the opening. When the terminal plateis mounted on the flange, an outer side surface of the terminal plateis flush with a surfaceof the casing in a portion where the opening is formed. With this structure, an electronic device can be obtained that is reliably waterproof and/or dustproof in a connection terminal portion that is exchangeable so as to enhance an expandability.

A main device includes fixing portions that fix a holding device to one principal surface thereof and project from the one principal surface. An extension device includes a placement portion on which the main device is placed and a wall portion on which the placement portion is provided in a standing manner. The wall portion that faces the one principal surface, to which the holding device is fixed, in a parallel relation, has such a shape as to not interfere with the fixing portions that fix the holding device of the main device, when the main device is placed on the placement portion. The main device can be mounted on the extension device with the holding device mounted thereon, and time and effort to remove the holding device can be saved when the main device is mounted on the extension device.
