Claim Text:
1. An extraction mechanism, comprising: a slider configured to release an engagement between a cage and a device inserted into the cage and engaged and latched to the cage, the slider being slidable in an insertion direction and an extraction direction of the device; an ejection part including an ejector that is slidable in the insertion direction and the extraction direction of the device, the ejection part being configured to eject the device out of the cage; a release lever configured to activate the slider and the ejection part; and a coil spring located between the slider and the ejector, the coil spring extending parallel to a longitudinal direction of the device and configured to energize the slider to the extraction direction and to energize the ejector to the insertion direction, wherein the ejector is configured to contact with the cage and to catch an energization force of the coil spring when the device is latched to the cage, by the release lever being moved to a release direction, the slider is configured to slide to the insertion direction, thereby compressing the coil spring to charge energy in the coil spring, and releasing the engagement between the cage and the device, by release of the engagement between the cage and the device, the energy charged in the coil spring is released to push the slider to the extraction direction, thereby ejecting the device out of the cage, and the extraction mechanism is provided to the device.
