  • Recording medium device ejection structure and apparatus body or adapter used for the structure
    Patent number: 6272091
    Abstract: The present invention provides a recording medium device ejection structure which is useful to minimize the outside dimension of a recording medium device and to increase the mounting area of a printed circuit on an adapter to which the recording medium device is inserted. The recording medium device comprises a recording medium body and a case having a recess for accommodating the recording medium body, and is attached to the adapter detachably. The adapter is provided with a cover, the first lever provided on the cover, and the second lever which is in contact with the first lever at one end. The first lever gets in the recess provided on the recording medium device to resultantly push up the recording medium device, and the recording medium device is thereby ejected. A connector not shown in the drawing to which the recording medium device is inserted does not necessarily have a recording medium device ejection mechanism, and thus the product is made small-sized.
