FIG. 3 illustrates the storage device of the electronic device in FIG. 2 is pulled out from the host and the carriage is moved out from the storage device. Referring to FIG. 3, since, the storage device 120 is slidably disposed to be able to pull out a predetermined distance with respect to the host 110, the distance between the storage device 120 and the host 110 is increased. Thus, the electronic device 100 facilitates the compact disc to be conveniently taken or replaced from the carriage 130. Moreover, as shown in FIG. 3, the storage device 120 is slidably disposed in the host 110 along a sliding direction S, and the carriage 130 is slidably disposed in the storage device 120 along the sliding direction S. When the carriage 130 is pulled from the storage device 120 to an end position, the storage device 120 just can be slid in the host 110. Such configuration in this embodiment has the advantage that the compact disc can be easily taken out or replaced from the carriage 130. The slidable carriage 130 is used to be one embodiment of the movable carriage, but the sorts of the movable carriage are not limited in the present invention. The carriage 130 also can rotate relative to the storage device 120 to be moved out of the storage device 120 (not shown in figures).
In the embodiment, the electronic device 100 is an all-in-one computer and further includes a display 160 fixed on the host 110. The storage device 120 can be any sort of optical storage device, for example, an optical disc device. In the embodiment, the carriage 130 is to carry the compact disc.
FIG. 4 schematically illustrates the storage device of the electronic device in FIG. 2. Referring to FIG. 2 and FIG. 4, in the embodiment, the storage device 120 includes a sliding plate 122 and a main body 124. The sliding plate 122 is slidably disposed in the host 110. The main body 124 is fixed on the sliding plate 122, wherein the carriage 130 is slidably disposed in the main body 124. The main body 124 is fixed on the sliding plate 122 by means of screws in this embodiment, but the way of fixing the main body 124 to the sliding plate 122 is not limited thereto.
Referring to FIG. 2 and FIG. 4, in the embodiment, the host 110 includes a casing 112, a frame 114 and a fixed plate 116. The frame 114 is fixed in the casing 112 by means of screws in this embodiment. In other embodiments, the frame 114 can be integrally formed with the casing 112. In other words, the frame 114 can be a part of the casing 112. The fixed plate 116 is fixed on the frame 114, wherein the storage device 120 is slidably disposed on the fixed plate 116.
FIG. 5 is an exploded view of part of the electronic device in FIG. 2. Please refer to FIG. 5, screws and standoffs are used for fixing the fixed plate 116 in the frame 114. The electronic device 100 further includes at least one sliding element 140 fixed at the fixed plate 116 and slidably disposed at the sliding plate 122. The sliding plate 122 slides in the casing 112 by means of the sliding element 140. The number of sliding elements 140 is not limited hereby in present invention. Two sliding elements 140 are used as an example in this embodiment. As shown in FIG. 5, the two sliding elements 140 are respectively disposed at the two ends of the fixed plate 116. In this embodiment, the material of the sliding element 140 is plastic in order to improve the smoothness of the sliding action, and any other appropriate material can be used for the sliding element 140. The force that is used to pull the carriage 130 out of the storage device 120 is smaller than the force that is used to pull the storage device 120 out of the host 110. Therefore, the carriage 130 can be pulled to slide to the end of the position at first and then the storage device 120 just can be slid in the host 110. When a user wants to take out the compact disc (CD) from the optical disc drive (ODD) by using multi-phase mechanism of the present invention, he/she needs to pull the carriage 130 sliding to the end of the position in the first phase and then the storage device 120 just can be slid in the host 110 in the second phase when he/she continually pulls the carriage 130. When the carriage 130 is pulled out of the storage device 120 and the storage device 120 or a partial of the storage device 120 is pulled out of the host 110, he/she can take out the compact disc from the optical disc drive more easily. When the electronic device comprises the multi-phase mechanism of the present invention, a user can take the content out of the storage device more easily and smoothly, wherein the content is compact disc.
FIGS. 6A and 6B illustrate the movements between the storage device and the fixed plate in FIG. 4. Referring to FIG. 2, FIG. 4, FIG. 5, FIGS. 6A and 6B, the electronic device 100 further includes at least one elastic element 150. The elastic element 150 is fixed at the fixed plate 116 and connected between the fixed plate 116 and the sliding plate 122. The number of the elastic elements 150 is not limited hereby in present invention. Two elastic elements 150 are used as an example in this embodiment. As shown in FIG. 5, the two elastic elements 150 are respectively disposed at the two ends of the fixed plate 116. The storage device 120 can be pulled out and retracted from the host 110 through the disposing of the elastic element 150. In this embodiment, the elastic element 150 is a torsional spring.
In FIG. 4, the storage device 120 is in a first position P1 which is the storage position. In FIG. 6A, the storage device 120 is in a second position P2 which is the midway position during the pulling process. In FIG. 6B, the storage device 120 is in a third position P3 which is in a fully retracted position. Particularly, by properly disposing the elastic element 150, the following effect is achieved. Resisting the elastic force of the elastic element 150 is required to pull out the storage device 120 from the first position P1 to the second position P2, such that the storage device 120 is prevented from unexpectedly sliding out from the host 110. In addition, the storage device 120 is able to move from the second position P2 to the third position P3 by means of elastic force of the elastic element 150. In this way, disposing of the elastic element 150 further has the advantage that it is laboursaving while the storage device 120 is pulled out from the host 110. The actions described above in FIG. 4, FIGS. 6A and 6B are performed in reverse orientation to have the storage device 120 retracted back into the host 110. In other words, the user can resist elastic force of the elastic element 150 to retract the storage device 120 from the third position P3 to the second position P2. Then similarly, the storage device 120 moves from the second position P2 to the first position P1 by means of elastic force of the elastic element 150.
In summary, according to the embodiments of the present invention, through the storage device slidably disposing in the host and being adapted to be pulled out or retracted from the host, it facilitates the user to take or replace a compact disc from an optical disc notwithstanding the all-in-one computer is configured with a larger display. And thus, the encountering problem that the larger display units become the obstructions when taking out the compact disc from the optical disc drive in all-in-one personal computers can be solved by the improved structure of ODD provided in the present invention.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
