Optical card drive with adaptive receiving tray and focusing adaptor

摘要

An optical card or disc drive having a card or disc adaptive receiving carrying tray. A compound pivot mechanism engages a spindle hub with a card or disc inserted and carried on the tray. The spindle and hub is supported by a base chassis, which pivots with respect to a main frame. A sub-chassis is pivot connected with the mainframe and elastically coupled with the base chassis. A cam member on the main frame engages the sub-chassis to pivot the sub-chassis coincident with the tray being level positioned or lowered relative to card spindle hub. The sub-chassis in turn pivots the base chassis to engage or disengage the disc with the spindle hub. The movement of the tray also activates a motor and roller combination to receive or eject the card into or from the tray. The tray accommodates card or discs and comprises mechanisms for securing the card or disc while the card disc is retracted into and ejected from the main frame. A card guide member acts to reposition the card into tray slot after the card disengaging from the spinning spindle hub for ejection out of mainframe. A focusing adapter member works to meet the optical pick unit focusing distance requirement for difference thickness of optical card or disc.
