A portable electronic apparatus includes an electronic main unit having a front surface, a rear surface, side surfaces, and a first electrical connector. The electronic main unit is served to perform arithmetic operation. The apparatus further includes a cover member provided on one of the side surfaces of the electronic main unit, for openably covering the front surface of the electronic main unit. The apparatus also includes an electronic sub-unit capable of being coupled with the electronic main unit. This electronic sub-unit has a support portion to be located behind the electronic main unit to support the rear surface, a handle portion projected from side of the electronic sub-unit for supporting the cover member when the cover member is opened, a second electrical connector capable of being connected to the first electrical connector, and an auxiliary electrical device capable of being cooperated with the electronic main unit.

Portable electronic apparatus

A flat and foldable electronic appliance which comprises a generally rectangular first flat casing having a pocket defined therein for accommodating a card for expansion of functions; a generally rectangular second flat casing similar in shape to the first flat casing and having a plurality of operating keys; a bridge member including at least two hinge joints for pivotably connecting the first and second flat casings together, one of the first and second flat casing being pivotable between folded and unfolded positions relative to the other of the first and second flat casings; and a generally cylindrical battery chamber provided on a portion of the bridge means other than the hinge joints. The generally cylindrical battery chamber is of a volume sufficient to accommodate therein at least one AA-size battery for powering electric and electronic circuits in the appliance and has a peripheral wall which is so curved as to follow the path of movement of such one of the first and second flat casings relative to the other of the first and second flat casings.

Flat and foldable electric appliance

An electronic card reading device for reading the data stored in an electronic card by electrically bringing the electronic card into contact with the reading device and for displaying the data that is read on a display thereof comprising; a main unit in the form of a thin plate having card contacts which are electrically brought into contact with an electronic card, an integrated circuit, and a display on which to display the data which is read from the electronic card, a power source in the form of a thin plate which is electrically connected to the main unit to supply power thereto, the power source being constructed so as to be separate from the main unit, and a soft cover having a housing portion for the main unit and another housing portion for the power source, in which the main unit and the power source are separately housed, and having an electronic card pocket which is so disposed that an electronic card can be inserted therein and the electronic card thus inserted is brought into contact with the card contacts of the main unit which is housed in the main unit housing portion.

A compact electronic apparatus comprises a main unit having at least a power supplying section and a display, at least one of several processing units having a key input section and a memory adapted to be removably attached to the main unit and a connecting section for connecting one of said processing units to the main unit. Each one of said processing units to the main unit. Each of the processing units has a different function.

A connector for a thin electronic appliance, for example, an IC card reader for electrically connecting the thin electronic appliance with its receiving member, for example, an IC card reader/writer, which comprises a detector switch key body of insulation rubber having a connector base rigidly secured to the receiving member, a plurality of contact electrodes of electrically conductive rubber securely held by the connector base, and a push button portion having a plurality of openings through which the contact electrodes extend. The key body is further provided with a plurality of resilient leg portions extending from the connector base and a key top portion carrying the push button portion and supported by the leg portions. The connector is combined with a detector switch having a plurality of stationary contacts rigidly secured to the receiving member and a movable contact rigidly secured to the lower surface of the key top portion. When the thin electronic appliance is properly set in the receiving member, its connection terminals are electrically connected to the contact electrodes upon depression of the key top portion of the key body and upon deformation of the leg portions. In this event, the detector switch detects that the thin electronic appliance has been properly set in its receiving member. When the thin electronic appliance is not in use, the contact electrodes are hidden inside the openings of the push button portion by virtue of the resiliency of the leg portions.
