An adapter, for a terminal unit, comprising a base housing having a mount surface for mounting of a terminal unit. A receptive space is defined by a plurality of walls on a part of the mount surface. A pair of guide rails are formed on the mount surface of the base housing, so as to be slidably engaged with the terminal unit. Overhanging guide plates extending from opposed side walls have edges facing to the mount surface, so as to be slidably engaged with the terminal unit. The guides rails and the edges serve to guide the terminal unit to introduce a part of the terminal unit into the receptive space. A pair of protrusions are formed on the mount surface, so as to be engaged with the terminal unit. The protrusions serve to detachably hold the terminal unit in a proper position on the mount surface to maintain the functional connection between the adapter and the terminal unit.

Adapter for terminal unit

A locking structure for releasably locking a covering element in a closed position on a unit housing. The locking structure includes a resiliently engaging member integrally formed on the covering element, and a supporting member pivotably connected to the covering element. The resiliently engaging member includes a pair of resilient first supports projecting from the covering element, a bar connecting the respective free ends of the resilient first supports with each other and a pair of projections formed on the bar to be releasably engaged with the housing. The supporting member includes a base plate pivotably connected to the covering element and a second support extending from the base plate to be releasably engaged with the resiliently engaging member. In a locked position of the locking structure, the bar is stably supported by the second support so that the projections are kept in engagement with the housing.

In an information processing system having a portable terminal unit, such as a hand-held computer, driven by a rechargeable battery and a data communication adaptor for enabling communication between the portable terminal unit and a host computer of the system, the terminal unit and the data communication adaptor are designed to minimize the size thereof in the following five ways. First, a memory card holding mechanism for connecting the memory card of the portable terminal unit is provided between a swinging back lid and a recess of the back casing. Second, a normal interface and a high-speed interface are both provided in the portable terminal unit and the the data communication adaptor respectively. Third, an auxiliary connector for an optional device to extend a function of the portable terminal Unit is provided in the opening of the casing of the portable terminal unit movable in three dimensions mounted on a printed circuit board. Fourth, a moisture resistant seal made of rubber or resin is molded integrally onto one of the joining edges of an upper casing and a lower casing. Fifth, an electric power source portion of the data communication adaptor is used not only for charging the battery of the portable terminal unit but also supplying a power adequate for enabling a data transmission operation thereof.
