Problems solved by technology

While it may be desirable or necessary to have a portion of some PC cards exposed to the environment during operation, there are clear risks associated with a peripheral device that extends beyond the boundaries of the computer in which it is installed, especially in the context of mobile computing devices such as notebook computers.
Specifically, the exposed portion of a PC card is susceptible to mechanical stress or damage at any time, but especially during times when the computer is being packed or transported.
A solution to this problem is to remove the PC card whenever it is not in use, but this solution has obvious drawbacks including the increased risk of loss when the PC card is separated from the computer and the time required for the operating system to recognize the device when it is later reinserted (PC cards are designed for plug and play compatibility).

Embodiment Construction

[0017] Generally speaking, the present invention contemplates a PC card slot that employs at least two insertion positions including a “housed” position in which the PC card is fully enclosed within the host computer and a “functional” position in which a portion of the PC card is external to the host computer. In one embodiment, the PC card is electrically disconnected from the host computer when it is in the housed position and becomes electrically connected when the card is moved from the housed position to the functional position. The PC card slot of the host computer may employ a push rod that is extended to a first position (fully extended) when the PC card is in the housed position. By forcing the push rod from the first position to a second position (partially extended), the PC card is moved from the housed position to the functional position. Further depression of the push rod ejects the card from the host computer. In any of the positions, the push rod may be “folded” so t...

Abstract

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.

Description

BACKGROUND [0001] 1. Field of the Present Invention [0002] The present invention is in the field of computing devices and more particularly in the field of computing devices having PC card slots. [0003] 2. History of Related Art [0004] The Personal Computer Memory Card International Association (PCMCIA) develops standards for low-cost, credit card-sized, interchangeable computer peripheral devices called PC Cards. The published specification for these devices is called the PC Card Standard. The PC Card Standard specifies the electrical and mechanical interface between the PC Card device and the socket it is plugged into. The standard also defines the software support needed to configure and control the device. The PCMCIA software architecture enables PC Cards to be configured dynamically at the time of insertion, thus providing hot-plugging capability. Hot plugging allows users to add (or remove) peripheral devices to their computer system without rebooting it. [0005] A PC Card is a...
