Cassette storage device

Abstract

A cassette storage device is disclosed, which is capable of storing a cassette having a first connector. The cassette storage device comprises: a housing having an opening and a second connector; a tray coupled to the housing and being moveable through the opening; a first shaft positioned between the housing and the tray; a second shaft positioned between the housing and the tray; a driving end coupled to the first shaft and the second shaft; and a releasing switch positioned on the housing and coupled to the first shaft. Therefore, when the first connector of the cassette is going to be ejected from the second connector of the housing, the releasing switch is only required to be pushed slightly, then the first shaft, along with the driving end will subsequently make the second shaft rotate and thus push the cassette out from the cassette storage device.

1 . A cassette storage device for storing an element with a first connector, the cassette storage device comprising:
 a housing having an opening, and a second connector corresponding to the first connector;   a tray coupled to the housing and capable of moving at the opening;   a first shaft positioned between the housing and the tray;   a second shaft positioned between the housing and the tray, the second shaft pivoted to the housing through a fulcrum for pushing the tray, while the first connector separates from the second connector;   a driving end coupled to the first shaft and the second shaft; and   a releasing switch positioned on the housing and coupled to the first shaft.   
   
   
       2 . The cassette storage device as claimed in  claim 1 , wherein the tray comprises a holding area and at least one side surface. 
   
   
       3 . The cassette storage device as claimed in  claim 1 , wherein the cassette storage device further comprises a tray locating unit for securing the tray to a stored position in an inner space of the housing. 
   
   
       4 . The cassette storage device as claimed in  claim 1 , wherein the cassette storage device further comprises a spring connected with the tray and the housing. 
   
   
       5 . The cassette storage device as claimed in  claim 1 , wherein the element is a hot-plug element. 
   
   
       6 . The cassette storage device as claimed in  claim 5 , wherein the hot-plug element is a hard disk drive. 
   
   
       7 . The cassette storage device as claimed in  claim 1 , wherein the second connector is a hot-plug connector. 
   
   
       8 . The cassette storage device as claimed in  claim 1 , wherein the material of the tray is plastic. 
   
   
       9 . The cassette storage device as claimed in  claim 1 , wherein the second shaft is a lever element having a first end connected with the driving end, a second end and a pivot. 
   
   
       10 . The cassette storage device as claimed in  claim 9 , wherein a distance between the first end and the fulcrum is smaller than a distance between the fulcrum and the second end. 
   
   
       11 . The cassette storage device as claimed in  claim 3 , wherein the tray locating unit is an elastic shifter. 
   
   
       12 . The cassette storage device as claimed in  claim 4 , wherein the quantity of the spring ranges from 1 to 4. 
   
   
       13 . The cassette storage device as claimed in  claim 1 , wherein the driving end is a universal joint. 
   
   
       14 . The cassette storage device as claimed in  claim 2 , wherein as the element separates from the cassette storage device, the second end of the second shaft contacts with the side surface of the tray. 
   
   
       15 . The cassette storage device as claimed in  claim 1 , wherein the cassette storage device further comprises a compression spring, the compression spring encompassing a part of the first shaft. 
   
   
       16 . The cassette storage device as claimed in  claim 15 , wherein the first shaft further comprises at least one protruding piece positioned on the surface of the first shaft and contacting with one end of the compression spring. 
   
   
       17 . A cassette storage device for fixing on a computer case to store a cassette therein, the cassette storage device comprising:
 a lower cover;   an upper cover;   a plurality of side plates connected with the lower cover and the upper cover;   a front plate having at least one opening;   a rear plate having an outer surface and at least one plug;   a button positioned on the front plate;   a lever element positioned at an outer surface of the rear plate, the lever element comprising a first end, a second end and a fulcrum positioned between the first end and the second end; and   a pushing rod positioned at the inner side of one of the side plates, two ends of the pushing rod connected with the button and the lever element, respectively;   wherein, as the cassette separates from the cassette storage device, the second end of the lever element contacts with the side surface of the cassette.
