A data processing device includes a chassis defining a card slot opening and a card received within the chassis. The card slot is operable to receive a peripheral card in a functional position in which a portion of the peripheral card is external to the chassis and the peripheral card is electrically connected to the system. The card slot is further operable to receive the peripheral card in a housed position wherein the peripheral card is entirely enclosed within the chassis. An embodiment of the card slot further includes means, such as a push button, for transitioning the peripheral card from the housed position to the functional position. In one embodiment, the peripheral is disconnected from the system and from electrical power when in the housed positioned.
A card type peripheral apparatus is disclosed which can be removably inserted not only into a slot of an electronic apparatus of a small size but also into a slot of an external apparatus readily and with certainty. The apparatus includes a first case, an electronic part accommodated in the first case, and a connector provided at a first end in the lengthwise direction of the first case for electrically connecting an external apparatus to the electronic part. The attachment includes a second case. Mounting portions are provided at a second end in the lengthwise direction of the first case and a first end in the lengthwise direction of the second case such that the first and second cases are removably attached to each other at the mounting portions thereof while the lengthwise directions thereof are juxtaposed with each other.
