A peripheral device adapted to be releasably secured to a host computer of the type having a standardized card slot. The peripheral device includes a card shaped portion attached to a module portion which houses an/input/output device. In one embodiment, the input/output device is an item identification reader, and the card shaped portion and module portion are integrally connected. Further, the card shaped portion is fitted into the card slot in the host computer to secure the peripheral device within the card slot to permit one handed operation of the host computer/peripheral device combination. The first embodiment also provides an electronic interface between the host computer and the peripheral device. In a second embodiment, the card shaped portion does not provide an electronic card interface. The card shaped portion and card slot merely engage to secure the peripheral device within the card slot. In this embodiment, the electronic interface is provided via a separate serial port connection. In a third embodiment of the invention, the card shaped portion and module portion are releasably attached to provide both one handed and two handed operation. A zigzag ribbon cable is utilized to maintain electrical connection between the module portion and card shaped portion when the respective portions are not attached to one another. A second and third embodiment may be combined to provide a card shaped portion releasably attached to a module portion wherein the electronic interface is provided via a separate serial port connection. |
